The present disclosure relates to an air conditioner system and a control method.
In an air conditioner system in which a plurality of indoor units are connected to one outdoor unit (hereinafter referred to as “air conditioner”), there is a technique in which each device communicates with an external server and an external terminal via a communication unit (for example, a network adapter) provided for each device in order to give operation instructions on operations of the indoor units and the outdoor unit and monitor operating states of the indoor units and the outdoor unit, using the external server and the external operation terminal (see, for example, Patent Document 1).
Further, in an air conditioner system in which a plurality of indoor units are connected to each of a plurality of outdoor units, there is a technique in which a predetermined one of the plurality of indoor units is connected to each outdoor unit, instead of a communication unit being provided for each indoor unit, and communicates with an external server and an external terminal via one communication unit to collectively manage information of each device (see, for example, Patent Document 2).
In the technique described in Patent Document 1, however, it is necessary to provide a communication unit for each device, thereby complicating communication processing and increasing costs. Further, in the technique described in Patent Document 2, although it is not necessary to provide a communication unit for each indoor unit, information of each of the plurality of outdoor units and the plurality of indoor units is sent via one communication unit, thereby requiring that a user register each device using an external terminal or the like in order to collectively manage the information of each device. Moreover, there have been cases where even if each device is registered, the user could not easily know which indoor unit is connected to which outdoor unit.
The present disclosure has been made in view of the above circumstances, and one object thereof is to provide an air conditioner system in which a plurality of indoor units are connected to one outdoor unit, and which makes it possible to collectively manage each device easily with a simple configuration.
The present disclosure has been made to solve the problems described above, an air conditioner system according to an aspect of the present disclosure is an air conditioner system in which an outdoor unit and a plurality of indoor units are connected via a communication line, and the an air conditioner system includes: a communication unit configured to communicate with an external device and one indoor unit of the plurality of indoor units; and a communication control unit configured to, as information for identifying each of the outdoor unit and the plurality of indoor units, associate first identification information uniquely set to each of the outdoor unit and the plurality of indoor units with second identification information uniquely set to the communication unit, and transmit from the one indoor unit the associated information to the external device via the communication unit.
A control method according to another aspect of the present disclosure is a control method for one indoor unit of a plurality of indoor units connected with an outdoor unit via a communication line in an air conditioner system. The control method includes: communicating with an external device via a communication unit; as information for identifying each of the outdoor unit and the plurality of indoor units, associating first identification information uniquely set to each of the outdoor unit and the plurality of indoor units with second identification information uniquely set to the communication unit; and transmitting the associated information from the one indoor unit to the external device via the communication unit.
According to the above aspect of the present disclosure, the air conditioner system in which the plurality of indoor units are connected to the one outdoor unit can collectively manage each device easily with a simple configuration.
Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
First, a first embodiment of the present disclosure will be described.
In the following description, the indoor units 20a, 20b, and 20c will be referred to as the indoor units 20 unless otherwise distinguished from one another. Similarly, the remote controllers 40a, 40b, and 40c will be referred to as remote controllers 40 unless otherwise distinguished from one another. Additionally, a quantity of indoor units 20 connected to one outdoor unit 10 is not limited to three, and may be arbitrary.
The outdoor unit 10 is a device that functions as an outdoor unit for each of the indoor units 20a, 20b, and 20c. Each of the indoor unit 20a, the indoor unit 20b, and the indoor unit 20c is communicatively connected to the outdoor unit 10 via a communication line 101. The communication line 101 is a wired communication line. For example, the communication line 101 to communicatively connect the outdoor unit 10 and the indoor unit 20a is wired along a piping route between the outdoor unit 10 and the indoor unit 20a. The communication line 101 to communicatively connect the outdoor unit 10 and the indoor unit 20b is wired along a piping route between the outdoor unit 10 and the indoor unit 20b. The communication line 101 to communicatively connect the outdoor unit 10 and the indoor unit 20c is wired along a piping route between the outdoor unit 10 and the indoor unit 20c.
The remote controller 40 is a remote controller that communicates with the indoor unit 20 using infrared rays. For example, the remote controller 40 outputs an operation instruction signal including operation details to the indoor unit 20 by infrared rays. The operation details given to the indoor unit 20 include, for example, operations to start and stop operation, an operation to switch among cooling operation, heating operation, and ventilating operation, an operation to set the set temperature, an operation to set an air volume, and the like. The indoor unit 20 receives an operation instruction signal output from the remote controller 40 and controls the operation based on the operation details included in the received operation instruction signal. In the illustrated example, the remote controllers 40a, 40b, and 40c are remote controllers for operating indoor units 20a, 20b, and 20c, respectively. Here, the remote controller 40 and the indoor unit 20 may communicate with each other via a communication line.
The antenna unit 30 is connected to the indoor unit 20a. The antenna unit 30 is an example of a communication unit for the indoor unit 20a and an external operation terminal 60 to communicate with each other via a repeater 50. For example, the antenna unit 30 is a communication device including an antenna for wirelessly connecting to a LAN (Local Area Network) provided in the building. The repeater 50 is, for example, a wireless LAN router that communicatively connects the LAN in the building and a public line, such as the Internet or a mobile phone communication network. The indoor unit 20a and the external operation terminal 60 can communicate with each other by connecting to the wireless LAN via the repeater 50.
The external operation terminal 60 is, for example, a terminal operated by a user, such as a smart phone or a tablet terminal. The external operation terminal 60 acquires information stored by each device of the outdoor unit 10 and the indoor units 20, and collectively manages the acquired information. The information stored by each device of the outdoor unit 10 and the indoor units 20 is, for example, information regarding an operating state of each device. The information regarding the operating state includes information indicating an operating state such as operating or stopped, information indicating an operating mode such as cooling, heating, or ventilating, setting information such as a set temperature and an air volume, detection information such as a room temperature, an outside temperature, or an internal temperature, and the like. The external operation terminal 60 periodically acquires information regarding an operating state from each device, and displays the operating state of each device.
Specifically, the external operation terminal 60 acquires information regarding an operating state of each device via the repeater 50 from the indoor unit 20a connected with the antenna unit 30. Here, each of the outdoor unit 10, the indoor units 20, and the antenna unit 30 is set with unique identification information. In the example shown in
The indoor unit 20a includes a control unit 230 configured to associate the identification information uniquely set to each of the outdoor unit 10 and the indoor units with the identification information uniquely set to the antenna unit 30 and transmit the associated information to the external operation terminal 60 via the antenna unit 30 and the repeater 50. For example, the control unit 230 associates information regarding an operating state of the indoor unit 20a with “ID21” and “ID31,” and transmits the associated information to the external operation terminal 60. Further, the control unit 230 acquires via the communication line 101 and the outdoor unit 10, information regarding an operating state of the indoor unit 20b which is associated with “ID22,” associates the acquired information regarding the operating state with “ID22” and “ID31,” and transmits the associated information to the external operation terminal 60. Further, the control unit 230 acquires via the communication line 101 and the outdoor unit 10, information regarding an operating state of the indoor unit 20c which is associated with “ID23,” associates the acquired information regarding the operating state with “ID23” and “ID31,” and transmits the associated information to the external operation terminal 60. Further, the control unit 230 acquires via the communication line 101, information regarding an operating state of the outdoor unit 10 which is associated with “ID11,” associates the acquired information regarding the operating state with “ID11” and “ID31,” and transmits the associated information to the external operation terminal 60. As a result, by communicating only with the indoor unit 20a, the external operation terminal 60 can acquire and monitor information regarding an operating state of each of the outdoor unit 10 and the plurality of indoor units 20 so that the information for each device is distinguishable from one another.
Setting of identification information in each device may be a hardware setting such as a setting by a slide switch provided in each device, or a software setting such that a setting is stored in a memory (storage unit) provided in each device by a setting operation or the like using the remote control 40. Further, the identification information can be arbitrarily changed by the above hardware setting or software setting.
Further, by using the identification information uniquely set to each of the outdoor unit 10 and the indoor units 20 and the identification information uniquely set to the antenna unit 30, the external operation terminal 60 can collectively give operation instructions on operations for the respective devices. Thus, the external operation terminal 60 can collectively manage each of the outdoor unit 10 and the plurality of indoor units 20 by communicating only with the indoor unit 20a.
Here, the external operation terminal 60 can be communicatively connected to the indoor unit 20a from outside the building. In that case, the repeater 50 includes a communication base station or the like for public lines, in addition to the wireless LAN router. In other words, the external operation terminal 60 can collectively manage each of the outdoor unit 10 and the plurality of indoor units 20 from outside the building as well as within a communicatively connectable range of the LAN inside the building.
Further, in lieu of, or in addition to, the external operation terminal 60, an external management server 70 can be communicatively connected to the indoor unit 20a via the repeater 50. For example, the external management server 70 may be a cloud server. By communicating only with the indoor unit 20a, the external management server 70 can acquire and monitor information regarding an operating state of each of the outdoor unit 10 and the plurality of indoor units 20 so that the information for each device is distinguishable from one another.
Further, by using the identification information uniquely set to each of the outdoor unit 10 and the indoor units 20 and the identification information uniquely set to the antenna unit 30, the external management server 70 may give operation instructions on operations for the respective devices and perform an automatic operation control or the like. Further, the external management server 70 may collectively manage not only the air conditioner system 1, but also electrical equipment other than the air conditioner system 1.
Next, a configuration of each device included in the air conditioner system 1 will be described in detail.
The outdoor unit 10 shown in
The wired communication unit 110 is configured to include a communication device for communicating with each indoor unit 20. The wired communication unit 110 is connected to each indoor unit 20 via the communication line 101. A storage unit 120 stores a control program for controlling operation of the outdoor unit 10, and the like. Further, the storage unit 120 stores the identification information (for example, “ID11”) and information regarding an operating state of the outdoor unit 10, information acquired from each indoor unit 20, and the like. The information acquired from each indoor unit includes the identification information and information regarding an operating state of each indoor unit 20, and the like.
An outdoor unit control unit 130 controls each unit included in the outdoor unit 10. For example, the outdoor unit control unit 130 includes a CPU (Central Processing Unit), a memory, and the like. The outdoor unit control unit 130 includes a communication control unit 131, an operation control unit 132, and a state detection unit 133, as functional configurations realized by executing the control program stored in the storage unit 120.
The communication control unit 131 controls communication with each of the indoor units 20a, 20b, and 20c via the wired communication unit 110 and the communication line 101. For example, the communication control unit 131 acquires from each of the indoor units 20a, 20b, and 20c, information regarding an operating state of a respective one of the indoor units 20a, 20b, and 20c. For example, the communication control unit 131 acquires information in which the identification information and information regarding an operating state of each of the indoor units 20a, 20b, and 20c are associated with each other, and causes the storage unit 120 to store the acquired information. Specifically, the communication control unit 131 periodically acquires the information in which the identification information and information regarding an operating state are associated with each other, and causes the storage unit 120 to store the acquired information.
Further, the communication control unit 131 transmits to the indoor unit 20a, the information in which the identification information and information regarding an operating state of each indoor unit 20 are associated with each other, which is stored in the storage unit 120. Further, the communication control unit 131 transmits to the indoor unit 20a, the information in which the identification information and information regarding an operating state of the outdoor unit 10 are associated with each other.
Here, the communication control unit 131 may acquire information in which the identification information and information regarding an operating state of each of at least the indoor units 20b and 20c are associated with each other, and cause the storage unit 120 to store the acquired information. Then, the communication control unit 131 may transmit to the indoor unit 20a, the information in which the identification information and information regarding an operating state of each of the indoor units 20b and 20c are associated with each other, which is stored in the storage unit 120. This is because the indoor unit 20a originally stores information in which the identification information and information regarding an operating state of the indoor unit 20a are associated with each other.
The operation control unit 132 controls operation of the outdoor unit 10. For example, the operation control unit 132 controls operation of the outdoor unit 10 based on the information regarding an operating state of each of the indoor units 20a, 20b, and 20c acquired from a respective one of the indoor units 20a, 20b, and 20c. Specifically, the operation control unit 132 controls operations of the compressor 141, the outdoor unit fan 143, and the like.
The state detection unit 133 detects a state of each unit of the outdoor unit 10. For example, the state detection unit 133 periodically detects an operating state (operating, stopped, or the like) of the outdoor unit 10 controlled by the operation control unit 132. Further, the state detection unit 133 periodically detects an internal temperature and an external air temperature based on sensor outputs of the internal temperature sensor 144 and the external air temperature sensor 145. The internal temperature sensor 144 is a temperature sensor provided inside the outdoor unit 10 to detect a temperature inside the outdoor unit 10. For example, the internal temperature sensor 144 detects a temperature of the heat exchanger 142 or the like. The external air temperature sensor 145 is a temperature sensor provided in the outdoor unit 10 to detect an external air temperature. The state detection unit 133 causes the storage unit 120 to store information such as the detected operating state, internal temperature, and external air temperature, as the information regarding an operating state.
Next, a configuration of the indoor unit 20 will be described. A basic configuration of each of the indoor units 20a, 20b, and 20c is the same, and the difference is that only the indoor unit 20a is connected to the antenna unit 30. In
The wired communication unit 210 is configured to include a communication device for communicating with the outdoor unit 10. The wired communication unit 210 is connected to the outdoor unit 10 via the communication line 101. The wired communication unit 210 of the indoor unit 20a is further connected to the antenna unit 30 via a communication line 102 and communicates with the antenna unit 30 as well.
The storage unit 220 stores a control program for controlling operation of the indoor unit 20, and the like. Further, the storage unit 220 stores the identification information and information regarding an operating state of the indoor unit 20.
For example, the storage unit 220 of the indoor unit 20a stores the identification information (“ID21”) and information regarding an operating state of the indoor unit 20a. Further, the storage unit 220 of the indoor unit 20a further stores the identification information (“ID11”) and information regarding an operating state of the outdoor unit 10, which are acquired from the outdoor unit 10, and the identification information (“ID22,” “ID23”) and information regarding operating states of the other indoor units 20b and 20c, which are acquired via the outdoor unit 10.
Similarly, the storage unit 220 of the indoor unit 20b stores the identification information (“ID22”) and information regarding an operating state of the indoor unit 20b, the identification information (“ID11”) and information regarding an operating state of the outdoor unit 10, and the identification information (“ID21,” “ID23”) and information regarding operating states of the other indoor units 20a and 20c. The storage unit 220 of the indoor unit 20c stores the identification information (“ID23”) and information regarding an operating state of the indoor unit 20c, the identification information (“ID11”) and information regarding an operating state of the outdoor unit 10, and the identification information (“ID21,” “ID22”) and information regarding operating states of the other indoor units 20a and 20b. In other words, the identification information and information regarding an operating state of the outdoor unit 10, and the identification information and information regarding an operating state of each indoor unit 20 are stored in, and shared by, each of the storage unit 120 of the outdoor unit 10 and the storage unit 220 of the indoor unit 20.
The indoor unit control unit 230 corresponds to the control unit 230 shown in
The communication control unit 231 controls communication with the outdoor unit 10 via the wired communication unit 210 and the communication line 101. For example, the communication control unit 231 of the indoor unit 20a associates the identification information (“ID21”) and information regarding an operating state of the indoor unit 20a with each other, and transmits the associated information to the outdoor unit 10. The communication control unit 231 of the indoor unit 20b associates the identification information (“ID22”) and information regarding an operating state of the indoor unit 20b with each other, and transmits the associated information to the outdoor unit 10. The communication control unit 231 of the indoor unit 20c associates the identification information (“ID23”) and information regarding an operating state of the indoor unit 20c with each other, and transmits the associated information to the outdoor unit 10.
Further, the communication control unit 231 of the indoor unit 20a acquires from the outdoor unit 10, the information in which the identification information and information regarding an operating state of each of the other indoor units 20b and 20c are associated with each other. Further, the communication control unit 231 acquires from the outdoor unit 10, the information in which the identification information and information regarding an operating state of the outdoor unit 10 are associated with each other. The communication control unit 231 causes the storage unit 220 to store each information acquired from the outdoor unit 10.
Further, the communication control unit 231 of the indoor unit 20a controls communication with the antenna unit 30 via the wired communication unit 210 and the communication line 102. The communication control unit 231 of the indoor unit 20a acquires the identification information (“ID31”) of the antenna unit 30 from the antenna unit 30 and causes the storage unit 220 to store the acquired identification information.
Further, the communication control unit 231 of the indoor unit 20a associates the information stored by each of the outdoor unit 10 and the indoor units 20a, 20b, and 20c with the identification information of a respective device and the identification information of the antenna unit 30, and transmits the associated information to the external operation terminal 60 via the antenna unit 30.
For example, the communication control unit 231 of the indoor unit 20a associates the identification information (“ID31”) of the antenna unit 30, the identification information (“ID11”) of the outdoor unit 10, and the information regarding an operating state of the outdoor unit 10 (operating, internal temperature, external air temperature, . . . ) with one another, and transmits the associated information as the operating state information of the outdoor unit 10 to the external operation terminal 60 via the antenna unit 30. Further, the communication control unit 231 of the indoor unit 20a associates the identification information (“ID31”) of the antenna unit 30, the identification information (“ID21”) of the indoor unit 20a, and the information regarding an operating state of the indoor unit 20a (operating, cooling, set temperature, internal temperature, room temperature, . . . ) with one another, and transmits the associated information as the operating state information of the indoor unit 20a to the external operation terminal 60 via the antenna unit 30. Further, the communication control unit 231 of the indoor unit 20a associates the identification information (“ID31”) of the antenna unit 30, the identification information (“ID22”) of the indoor unit 20b, and the information regarding an operating state of the indoor unit 20b (operating, cooling, set temperature, internal temperature, room temperature, . . . ) with one another, and transmits the associated information as the operating state information of the indoor unit 20b to the external operation terminal 60 via the antenna unit 30.

Further, the communication control unit 231 acquires operation instruction information indicating operation instructions for each of the indoor units 20a, 20b, and 20c from the external operation terminal 60 via the antenna unit 30. In the operation instruction information, the identification information of the indoor unit 20 to be operated, the identification information of the antenna unit 30, and the information indicating operation details are associated with one another. The operation details refer to the details of operation for the indoor unit 20, such as an operation to start operation, an operation to stop operation, an operation to switch between cooling operation, heating operation, and ventilating operation, an operation to set a set temperature, an operation to set an air volume, and the like.
Returning to
Further, when the communication control unit 231 of the indoor unit 20a acquires the operation instruction information in which the identification information (“ID31”) of the antenna unit 30 and the identification information (“ID21”) of the indoor unit 20a are associated with each other, the operation control unit 232 of the indoor unit 20a controls operation of the indoor unit 20a based on the operation details included in the operation instruction information. When the communication control unit 231 of the indoor unit 20b acquires the operation instruction information in which the identification information (“ID31”) of the antenna unit 30 and the identification information (“ID22”) of the indoor unit 20b are associated with each other, the operation control unit 232 of the indoor unit 20b controls operation of the indoor unit 20b based on the operation details included in the operation instruction information. When the communication control unit 231 of the indoor unit 20c acquires the operation instruction information in which the identification information (“ID31”) of the antenna unit 30 and the identification information (“ID23”) of the indoor unit 20c are associated with each other, the operation control unit 232 of the indoor unit 20c controls operation of the indoor unit 20c based on the operation details included in the operation instruction information. In other words, each of the indoor units controls operation thereof based on the operation details included in the operation instruction information when it is identified to be the operation target by the identification information of the indoor unit 20 included in the operation instruction information acquired by the communication control unit 231.
The state detection unit 233 detects a state of each unit of the indoor unit 20. The state detection unit 233 periodically detects an operating state (operating, stopped, set temperature, or the like) of the indoor unit 20 controlled by the operation control unit 232. Further, the state detection unit 233 periodically detects an internal temperature and a room temperature based on sensor outputs of the internal temperature sensor 244 and the room temperature sensor 245. The internal temperature sensor 244 is a temperature sensor provided inside the indoor unit 20 to detect a temperature inside the indoor unit 20. For example, the internal temperature sensor 244 detects a temperature of the heat exchanger 242 or the like.

The wireless communication unit 320 is configured to include a communication device for wirelessly communicating with the repeater 50. For example, the repeater 50 is a wireless LAN router. The wireless communication unit 320 is configured to include a communication device such as an antenna for connecting to the repeater 50 via a wireless LAN.
The storage unit 330 stores the identification information (“ID31”) of the antenna unit 30, a control program for controlling operation of the antenna unit 30, and the like.
The communication control unit 340 is configured to include a CPU, a memory, and the like. The communication control unit 340 controls each unit of the antenna unit by executing the control program stored in the storage unit 330. Specifically, the communication control unit 340 controls communication with the indoor unit 20a via the wired communication unit 310. Further, the communication control unit 340 controls communication with the repeater 50 via the wireless communication unit 320.
When the antenna unit 30 is connected to the indoor unit 20a, the communication control unit 340 performs negotiation for a communication speed and a communication method, transmits the information of the antenna unit 30 to the indoor unit 20a via the wired communication unit 310, and also receives the information of the indoor unit 20a from the indoor unit 20a via the wired communication unit 310.

Further, the communication control unit 340 receives the identification information (“ID21”) of the indoor unit 20a from the indoor unit 20a.
After communication is established by the negotiation, the communication control unit 340 acquires various information transmitted from the indoor unit 20a via the wired communication unit 310, and transmits the acquired various information to the repeater 50 via the wireless communication unit 320. Further, the communication control unit 340 acquires various information transmitted from the repeater 50 via the wireless communication unit 320, and transmits the acquired various information to the indoor unit 20a via the wired communication unit 310.
Next, a flow of processing in the air conditioner system 1 will be described.
First, a flow of initialization processing for grouping the identification information of the devices connected to the air conditioner system 1 to make them recognizable by the external operation terminal 60 will be described.
(Step S101) When the antenna unit 30 is connected to the indoor unit 20a, the antenna unit 30 and the indoor unit 20a perform a negotiation process for communication. In the negotiation process, the antenna unit 30 transmits the identification information (“ID31”) of the antenna unit 30 to the indoor unit 20a. The indoor unit 20a acquires and stores the identification information (“ID31”) of the antenna unit 30 transmitted from the antenna unit 30.
(Step S103) The indoor unit 20a transmits the identification information (“ID21”) of the indoor unit 20a to the outdoor unit 10. The outdoor unit 10 acquires the identification information (“ID21”) of the indoor unit 20a transmitted from the indoor unit 20a and stores the acquired identification information in the storage unit 220.
(Step S105) The indoor unit 20b transmits the identification information (“ID22”) of the indoor unit 20b to the outdoor unit 10. The outdoor unit 10 acquires the identification information (“ID22”) of the indoor unit 20b transmitted from the indoor unit 20b and stores the acquired identification information in the storage unit 220.
(Step S107) The indoor unit 20c transmits the identification information (“ID23”) of the indoor unit 20c to the outdoor unit 10. The outdoor unit 10 acquires the identification information (“ID23”) of the indoor unit 20c transmitted from the indoor unit 20c and stores the acquired identification information in the storage unit 220.
(Step S109) The outdoor unit 10 associates the identification information (“ID21”) of the indoor unit 20a, the identification information (“ID22”) of the indoor unit 20b, and the identification information (“ID23”) of the indoor unit 20c with the identification information (“ID11”) of the outdoor unit 10 to group them into an identification information group of the devices included in the air conditioner system 1. Then, the outdoor unit 10 transmits the grouped identification information group to the indoor unit 20a. The indoor unit 20a acquires the identification information group transmitted from the outdoor unit 10 and stores the acquired identification information group in the storage unit 220 of the indoor unit 20a.
(Step S111) The indoor unit 20a associates the identification information group (“ID11”, “ID21”, “ID22”, “ID23”) acquired from the outdoor unit 10 with the identification information (“ID31”) of the antenna unit 30, and transmits the associated information to the external operation terminal 60. By associating the identification information (“ID31”) of the antenna unit 30, it is possible to distinguish the identification information group of the devices included in this air conditioner system 1 and an identification information group of devices included in another air conditioner system. The identification information group data transmitted from the indoor unit 20a to the external operation terminal 60 is first transmitted from the indoor unit 20a to the antenna unit 30 (step S111A), then is transmitted from the antenna unit 30 to the repeater 50 (step S111B), and then is transmitted from the repeater 50 to the external operation terminal 60 (step S111C). As a result, the external operation terminal 60 can identify the devices included in the air conditioner system 1 using the identification information of each device.
Next, a flow of processing for monitoring an operating state of each device of the air conditioner system 1 using the external operation terminal 60 will be described.
(Step S201) The indoor unit 20a detects information regarding an operating state of the indoor unit 20a, associates the detected information regarding the operating state with the identification information (“ID21”) of the indoor unit 20a, and stores the associated information in the storage unit 220 of the indoor unit 20a.
(Step S203) The indoor unit 20a transmits to the outdoor unit 10, the information in which the information regarding the operating state and the identification information (“ID21”) are associated with each other. The outdoor unit 10 acquires the information in which the information regarding the operating state and the identification information (“ID21”) are associated with each other, which is transmitted from the indoor unit 20a, and stores the acquired information in the storage unit 120.
(Step S205) The indoor unit 20b detects information regarding an operating state of the indoor unit 20b, associates the detected information regarding the operating state with the identification information (“ID22”) of the indoor unit 20b, and stores the associated information in the storage unit 220 of the indoor unit 20b.
(Step S207) The indoor unit 20b transmits to the outdoor unit 10, the information in which the information regarding the operating state and the identification information (“ID22”) are associated with each other. The outdoor unit 10 acquires the information transmitted from the indoor unit 20b in which the identification information (“ID22”) and information regarding the operating state are associated with each other, and stores the acquired information in the storage unit 120.
(Step S209) The outdoor unit 10 transmits to the indoor unit 20a, the information acquired from the indoor unit 20b in which the information regarding the operating state and the identification information (“ID22”) are associated with each other. The indoor unit 20a stores in the storage unit 220 of the indoor unit 20a, the information transmitted from the outdoor unit 10 in which the identification information (“ID22”) and information regarding the operating state of the indoor unit 20b are associated with each other.
(Step S211) The indoor unit 20c detects information regarding an operating state of the indoor unit 20c, associates the detected information regarding the operating state with the identification information (“ID23”) of the indoor unit 20c, and stores the associated information in the storage unit 220 of the indoor unit 20c.
(Step S213) The indoor unit 20c transmits to the outdoor unit 10, the information in which the information regarding the operating state the identification information (“ID23”) are associated with each other. The outdoor unit 10 acquires the information transmitted from the indoor unit 20c in which the identification information (“ID23”) and information regarding the operating state are associated with each other, and stores the acquired information in the storage unit 120.
(Step S215) The outdoor unit 10 transmits to the indoor unit 20a, the information acquired from the indoor unit 20c in which the information regarding the operating state and identification information (“ID23”) are associated with each other. The indoor unit 20a stores in the storage unit 220 of the indoor unit 20a, the information transmitted from the outdoor unit 10 in which the identification information (“ID23”) and information regarding the operating state of the indoor unit 20c are associated with each other.
(Step S217) The outdoor unit 10 detects information regarding an operating state of the outdoor unit 10, associates the detected information regarding the operating state with the identification information (“ID11”) of the outdoor unit 10, and stores the associated information in the storage unit 120.
(Step S219) The outdoor unit 10 transmits to the indoor unit 20a, the information in which the information regarding the operating state and the identification information (“ID11”) are associated with each other. The indoor unit 20a stores in the storage unit 220 of the indoor unit 20a, the information transmitted from the outdoor unit 10 in which the identification information (“ID11”) and information regarding the operating state of the outdoor unit 10 are associated with each other.
(Step S221) The indoor unit 20a generates operating state information of the outdoor unit 10 (see
(Step S223) The indoor unit 20a transmits to the external operation terminal 60, the operating state information of the outdoor unit 10, the operating state information of the indoor unit 20a, the operating state information of the indoor unit 20b, and the operating state information of the indoor unit 20c. Each operating state information transmitted from the indoor unit 20a to the external operation terminal 60 is first transmitted from the indoor unit 20a to the antenna unit 30 (step S223A), then is transmitted from the antenna unit 30 to the repeater 50 (step S223B), and then is transmitted from the repeater 50 to the external operation terminal 60 (step S223C). As a result, the external operation terminal 60 can monitor an operating state of each device included in the air conditioner system 1.
Here, the processing from step S201 to step S223 is repeatedly performed at a predetermined interval. Further, the order of processes in which the outdoor unit 10 and each indoor unit 20 detect and transmit an operating state may be changed. Further, the processes in which the outdoor unit 10 and each indoor unit 20 detect and transmit an operating state may be performed synchronously with a specific period.
Next, a flow of operation instruction processing when an operation instruction for the air conditioner system 1 is given from the external operation terminal 60 will be described. Using the external operation terminal 60, the user can collectively give operation instructions to the respective devices of the air conditioner system 1.
(Step S301) The external operation terminal 60 receives a user operation for the indoor unit 20 to be operated by the air conditioner system 1. For example, the external operation terminal 60 displays an operation screen for receiving respective operations for the indoor units 20a, 20b, and 20c, and receives user operations on the operation screen.
Operation details for each of the indoor unit 20a, the indoor unit 20b, and the indoor unit 20c are received on this operation screen, where the operation details include operations to start and stop operation, an operation to switch among cooling operation, heating operation, and ventilating operation, an operation to set a set temperature, an operation to set an air volume, and the like.
(Step S303) The external operation terminal 60 generates operation instruction information based on the user operation received in step S301. The operation instruction information includes the identification information of the antenna unit 30 for specifying the air conditioner system 1 to be operated, the identification information of the indoor unit to be operated, and the operation details, which are associated with one another (see
(Step S305) The external operation terminal 60 transmits the operation instruction information to the air conditioner system 1. A timing of transmission is a timing according to the user operation in step S301 or a timing according to a preset operation plan. The operation instruction information transmitted from the external operation terminal 60 to the air conditioner system 1 is first transmitted from the external operation terminal 60 to the repeater 50 (step S305A), then is transmitted from the repeater 50 to the antenna unit 30 (step S305B), and then is transmitted from the antenna unit 30 to the indoor unit 20a (step S305C).
(Step S307) When the indoor unit 20a receives the operation instruction information transmitted from the external operation terminal 60, if the operation instruction information includes the identification information (“ID31”) of the antenna unit 30, the indoor unit 20a transmits the operation instruction information to the outdoor unit 10. Further, in this case, the indoor unit 20a proceeds to the process of step S313.
(Steps S309, S311) When receiving the operation instruction information transmitted from the indoor unit 20a, the outdoor unit 10 transmits the operation instruction information to the indoor unit 20b and the indoor unit 20c. The order of transmission to the indoor unit 20b and the indoor unit 20c may be either first or at the same time.
(Step S313) Based on the identification information of the indoor unit 20 included in the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20a determines whether or not the indoor unit 20a is an operation target.
When the identification information of the indoor unit 20 included in the operation instruction information is the identification information (“ID21”) of the indoor unit 20a, the indoor unit 20a determines that the indoor unit 20a is the operation target, and proceeds to the process of step S315. On the other hand, when the identification information of the indoor unit 20 included in the operation instruction information is not the identification information (“ID21”) of the indoor unit 20a, the indoor unit 20a determines that the indoor unit 20a is not the operation target, and does not perform the process of step S315.
(Step S315) When the indoor unit 20a is the operation target of the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20a controls operation based on the operation instruction information. Specifically, the indoor unit 20a performs control according to the operation details included in the operation instruction information.
(Step S317) Based on the identification information of the indoor unit 20 included in the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20b determines whether or not the indoor unit 20b is an operation target. When the identification information of the indoor unit 20 included in the operation instruction information is the identification information (“ID22”) of the indoor unit 20b, the indoor unit 20b determines that the indoor unit 20b is the operation target, and proceeds to the process of step S319. On the other hand, when the identification information of the indoor unit 20 included in the operation instruction information is not the identification information (“ID22”) of the indoor unit 20b, the indoor unit 20b determines that the indoor unit 20b is not the operation target, and does not perform the process of step S319.
(Step S319) When the indoor unit 20b is the operation target of the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20b controls operation based on the operation instruction information. Specifically, the indoor unit 20b performs control according to the operation details included in the operation instruction information.
(Step S321) Based on the identification information of the indoor unit 20 included in the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20c determines whether or not the indoor unit 20c is an operation target. When the identification information of the indoor unit 20 included in the operation instruction information is the identification information (“ID23”) of the indoor unit 20c, the indoor unit 20c determines that the indoor unit 20c is the operation target, and proceeds to the process of step S323. On the other hand, when the identification information of the indoor unit 20 included in the operation instruction information is not the identification information (“ID23”) of the indoor unit 20c, the indoor unit 20c determines that the indoor unit 20c is not the operation target, and does not perform the process of step S323.
(Step S323) When the indoor unit 20c is the operation target of the operation instruction information transmitted from the external operation terminal 60, the indoor unit 20c controls operation based on the operation instruction information. Specifically, the indoor unit 20c performs control according to the operation details included in the operation instruction information.
As described above, in the air conditioner system 1 according to the present embodiment, one outdoor unit 10 and the plurality of indoor units 20 are connected via the communication line 101. The air conditioner system 1 is configured to include the antenna unit 30 (an example of a communication unit) and the communication control unit 231. The antenna unit 30 communicates with the external operation terminal 60 (an example of an external device) and one of the outdoor unit 10 and the plurality of indoor units 20. The communication control unit 231 associates the identification information (first identification information) uniquely set to each of the outdoor unit 10 and the plurality of indoor units 20 with the identification information uniquely set to the antenna unit 30 (second identification information), and transmits the associated information to the external operation terminal 60 (the example of the external device) via the antenna unit 30.
As a result, the air conditioner system 1 can identify the air conditioner system 1 and each device using the identification information of the antenna unit 30 and the identification information of each device of the outdoor unit 10 and the plurality of indoor units 20. Therefore, it is possible to collectively manage each device from an external device (for example, the external operation terminal 60) easily with a simple configuration.
For example, the communication control unit 231 associates the information stored by each of the outdoor unit 10 and the plurality of indoor units 20 with the identification information (first identification information) of a respective one of the outdoor unit 10 and the plurality of indoor units 20 and the identification information (second identification information) of the antenna unit 30, and transmits the associated information to the external operation terminal 60 via the antenna unit 30.
As a result, the air conditioner system 1 can identify the information of the air conditioner system 1 and each device using the identification information of the antenna unit 30 and the identification information of each device of the outdoor unit 10 and the plurality of indoor units 20. Therefore, it is possible to collectively manage the information of each device from an external device (for example, the external operation terminal 60) easily with a simple configuration.
Here, the information stored by each of the outdoor unit 10 and the plurality of indoor units 20 includes information regarding a state of a respective one of the outdoor unit 10 and the plurality of indoor units 20.
As a result, the air conditioner system 1 can easily monitor a state of each device from an external device with a simple configuration. Here, the state of each device is, for example, information regarding an operating state of a respective one of the outdoor unit and the plurality of indoor units 20. As described above, the information regarding an operating state includes information indicating an operating state such as operating or stopped, information indicating an operating mode such as cooling, heating, or ventilating, set information such as a set temperature and an air volume, detection information such as a room temperature, an external air temperature, or an internal temperature, and the like. As a result, the air conditioner system 1 can easily monitor an operating state of each device from an external device (for example, the external operation terminal 60) with a simple configuration.
Among the outdoor unit 10 and the plurality of indoor units 20, a device (for example, the indoor unit 20a) configured to communicate with the external operation terminal 60 via the antenna unit 30 includes the communication control unit 231. The device (for example, the indoor unit 20a) configured to communicate with the external operation terminal 60 acquires from each of the other devices among the outdoor unit 10 and the plurality of indoor units 20, information stored by a respective one of the other devices. Then, the device (for example, the indoor unit 20a) configured to communicate with the external operation terminal 60 associates the information acquired from each of the other devices with the identification information (first identification information) of a respective one of the other devices, and stores the associated information.
As a result, in the air conditioner system 1, only one device (for example, the indoor unit 20a) among the outdoor unit 10 and the plurality of indoor units 20 communicates with the external operation terminal 60 via the antenna unit 30, so that an operating state of each of the outdoor unit 10 and the plurality of indoor units 20 can be monitored from an external device (for example, the external operation terminal 60).
The communication control unit 231 acquires from the external operation terminal 60 via the antenna unit 30, operation instruction information in which operation details and the identification information (first identification information) of an indoor unit 20 to be an operation target among the plurality of indoor units 20 are associated with the identification information (second identification information) of the antenna unit 30. Each of the plurality of indoor units 20 includes the operation control unit 232 configured to control operation based on the operation details included in the operation instruction information, when a respective one of the plurality of indoor units 20 is identified to be the operation target by the identification information (first identification information) included in the operation instruction information acquired by the communication control unit 231.
As a result, in the air conditioner system 1, it is possible to give an operation instruction from an external device (for example, the external operation terminal 60) individually to each of the indoor units 20 included in the air conditioner system 1. Here, the air conditioner system 1 may be configured to simultaneously give operation instructions each including the same operation details to the respective indoor units 20 included in the air conditioner system 1.
Further, the antenna unit 30 is configured to communicate with the external operation terminal 60 via the repeater 50 (an example of a communication relay device). As a result, the air conditioner system 1 can transmit and receive information to and from an external device (for example, the external operation terminal 60) communicatively connected via the repeater 50.
For example, when the repeater 50 is a wireless LAN router and the antenna unit is connected to the wireless LAN, in the air conditioner system 1, one device (for example, the indoor unit 20a) communicates with an external device (for example, the external operation terminal 60) via the wireless LAN. Therefore, it is not necessary to connect the plurality of indoor units 20 to an external device (for example, the external operation terminal 60) via communication lines, thereby achieving a simple configuration. Further, it is not necessary to connect the plurality of indoor units 20 to an external device (for example, the external operation terminal 60) via communication lines, thereby decreasing a risk of communication failure due to disconnection or the like.
In the above case, the air conditioner system 1 can communicate with an external device (for example, the external operation terminal 60) within a communication range of the wireless LAN. On the other hand, in lieu of, or in addition to, the wireless LAN router, a base station for public lines, such as mobile phone communication networks, may be included in the repeater 50. In this case, the air conditioner system 1 can also communicate with an external device (for example, the external operation terminal 60) outside the communication range of the wireless LAN (outdoors, or the like).
Here, the communication method described above is an example, and any communication method can be applied. For example, when the air conditioner system 1 communicates with an external device (for example, the external operation terminal 60) indoors, the communication may be performed using Bluetooth (registered trademark) or the like without using the repeater 50. Further, the communication unit, for which the antenna unit 30 has been described as an example, may be a LAN adapter connected to a wired LAN. In other words, one device (for example, the indoor unit 20a) in the air conditioner system 1 and an external device (for example, the external operation terminal 60) may be connected via a communication line (wired).
Further, in the air conditioner system 1, the quantity of antenna units 30 is less than the total quantity of the outdoor unit 10 and the plurality of indoor units 20. As a result, the air conditioner system 1 can communicate with an external device (for example, the external operation terminal 60) with a simple configuration.
Here, in the air conditioner system 1, an indoor unit 20 to be connected to the outdoor unit 10 can be added or deleted later. When an indoor unit 20 is added or deleted, the air conditioner system 1 can update the information of the indoor unit(s) 20 connected to the outdoor unit 10 by performing the initialization process shown in
Further, the configuration may be not only that each indoor unit 20 is connected to the outdoor unit 10 by a communication line, but also that each indoor unit 20 may be connected to each other by a communication line. As a result, each indoor unit 20 may directly acquire the information of the other indoor units 20 without using the outdoor unit 10.
Further, in the example of the present embodiment, the example in which the antenna unit 30 is externally connected to the indoor unit 20a has been illustrated, but the antenna unit 30 may be built in the indoor unit 20a. Further, in the example of the present embodiment, the example in which the antenna unit 30 is connected to the indoor unit 20a has been illustrated, but the device to be connected with the antenna unit 30 may be any of the indoor units 20, or may be the outdoor unit 10. In lieu of the indoor unit 20a described above, a device to be connected with the antenna unit 30 may perform the above-described communication with the external operation terminal 60 or the external management server 70. Further, the outdoor unit 10 and the plurality of indoor units 20 may include a device to be connected with a spare antenna unit 30, in addition to the device to be connected with the antenna unit 30. For example, when the antenna unit 30 is connected to the indoor unit 20a and a spare antenna unit 30 is connected to the indoor unit 20b, if a failure occurs in communication via the antenna unit 30 by the indoor unit 20a, the indoor device 20b may perform communication using the spare antenna unit 30. Alternatively, the configuration may be such that antenna units 30 are connected respectively to the outdoor unit 10 and the indoor units 20, and only one of the antenna units 30 functions.
Here, the description has been made in the present embodiment with respect to the example in which the identification information and operating state information of the outdoor unit 10 and the identification information and operating state information of each indoor unit 20 are stored in, and shared by, the storage unit 120 of the outdoor unit 10 and the storage unit 220 of the indoor unit 20, but the example is not limited thereto. The identification information and operating state information of the outdoor unit 10 and the identification information and operating state information of each indoor unit 20 may be stored only in the device (for example, the indoor unit 20a) connected with the antenna unit 30.
Next, a second embodiment of the present disclosure will be described. In the first embodiment, the example in which the external operation terminal 60 collectively manages one air conditioner system 1 has been described, while in the present embodiment, an example in which a plurality of air conditioner systems are collectively managed will be described.
The air conditioner system 1A includes one outdoor unit 10 (10A), three indoor units 20 (20Aa, 20Ab, 20Ac), an antenna unit 30 (30A), and remote controllers 40 (40Aa, 40Ab, 40Ac) corresponding respectively to the three indoor units 20. A basic configuration of the air conditioner system 1A is the same as the configuration of the air conditioner system 1 shown in
The air conditioner system 1B includes one outdoor unit 10 (10B), two indoor units 20 (20Ba, 20Bb), an antenna unit 30 (30B), and remote controllers 40 (40Ba, 40Bb) corresponding respectively to the two indoor units 20. A basic configuration of the air conditioner system 1B is the same as the configuration of the air conditioner system 1 shown in
The air conditioner system 1G includes one outdoor unit 10 (10G), three indoor units 20 (20Ga, 20Gb, 20Gc), an antenna unit 30 (30G), and remote controllers 40 (40Ga, 40Gb, 40Gc) corresponding respectively to the three indoor units 20. A basic configuration of the air conditioner system 1G is the same as the configuration of the air conditioner system 1 shown in
Further, in the air conditioner system 1A, identification information of the outdoor unit 10A is set to “ID11,” identification information of the indoor units 20Aa, 20Ab, and 20Ac are set respectively to “ID21,” “ID22,” and “ID23,” and identification information of the antenna unit 30A is set to “ID31.” In the air conditioner system 1B, identification information of the outdoor unit 10B is set to “ID12,” identification information of the indoor units 20Ba and 20Bb are set respectively to “ID24” and “ID25,” and identification information of the antenna unit 30B is set to “ID32.” In the air conditioner system 1G, identification information of the outdoor unit 10G is set to “ID11,” identification information of the indoor units 20Ga, 20Gb, and 20Gc are set respectively to “ID21,” “ID22,” and “ID23,” and identification information of the antenna unit 30G is set to “ID33.”
Since the identification information of the antenna unit 30 of each of the air conditioner systems 1A, 1B, . . . , and 1G differs from one another, the external operation terminal 60 can distinguish each of the air conditioner systems 1A, 1B, . . . , and 1G. On the other hand, the identification information of the outdoor unit 10 and the indoor units differ between the air conditioner system 1A and the air conditioner system 1B, and are the same between the air conditioner system 1A and the air conditioner system 1G. Since the identification information of the antenna unit 30 for each air conditioner system differs from one another, the external operation terminal 60 can distinguish the outdoor unit 10 and the plurality of indoor units 20 of the air conditioning system 1A from the outdoor unit and the plurality of indoor units 20 of the air conditioning system 1G, even when the identification information of the outdoor unit 10 and the indoor units 20 are the same between the air conditioner system 1A and the air conditioner system 1G.
Therefore, in the present embodiment, the external operation terminal 60 can distinguish, monitor an operating state of, and give operation instructions to, each of the outdoor unit 10 and the plurality of indoor units 20 of each of the plurality of air conditioning systems 1A, 1B, . . . , and 1G.
Here, the quantity of indoor units 20 included in each of the air conditioner system 1A, the air conditioner system 1B, and the air conditioner system 1G shown in
Here, in the example of the monitoring screen shown in
As described above, an operating state of each device of the outdoor unit 10 and the indoor units 20 included in each of the plurality of air conditioning systems 1A, 1B, . . . , and 1G can be monitored from an external device (for example, the external operation terminal 60). Further, an external device (for example, the external operation terminal 60) can give an operation instruction to each device of the indoor units 20 included in each of the plurality of air conditioner systems 1A, 1B, . . . , and 1G. Therefore, each device of the outdoor unit 10 and the indoor units 20 of each of the plurality of air conditioning systems 1A, 1B, . . . , and 1G can be collectively managed from an external device (for example, the external operation terminal 60) easily with a simple configuration.
Here, a program for realizing the functions of the outdoor unit control unit 130, the indoor unit control unit 230, and the communication control unit 340 may be recorded in a computer-readable recording medium, so that a computer system can read and execute the program recorded in the recording medium to perform the processing of each control unit. Here, the “computer system” referred to here includes an OS and hardware such as peripheral devices.
Further, the “computer-readable recording medium” refers to portable media such as flexible disks, magneto-optical disks, ROMs and CD-ROMs, and storage devices such as hard disks built into computer systems. Further, the “computer-readable recording medium” includes: a medium that dynamically retains a program for a short period of time, like a communication line in a case where the program is transmitted via a network such as the Internet or a communication line such as a telephone line; and a medium that retains a program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or a client in the above case. Further, the program may be one for realizing part of the functions described above, or may be one capable of realizing the functions described above in combination with a program already recorded in the computer system. Further, the above program may be stored in a predetermined server, so that it will be distributed (downloaded, or the like) via a communication line in response to a request from another device.
Further, part or all of the functions of the outdoor unit control unit 130, the indoor unit control unit 230, and the communication control unit 340 may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each function may be individually processorized, and part or all of the functions may be integrated and processorized. Further, the integrated circuit is not limited to LSI, and may be realized as a dedicated circuit or a general-purpose processor. Further, when an integrated circuit technology that replaces LSI appears due to advances in semiconductor technology, an integrated circuit based on that technology may be used.
Although the embodiments of the present disclosure have been described in detail with reference to the drawings, the specific configurations are not limited to these embodiments, and includes designs and the like, which do not deviate from the gist of the present disclosure.
