<1. System Configuration>
[Overall Configuration]
This sensing system includes a plurality of IoT devices 100, a device management apparatus 200, a base station 300, and a server 500. The IoT devices 100 and the base station 300 are connected by wireless communication. The base station 300 and the server 500 are connected via a network 400.
Each of the IoT devices 100 is a sensing device having a wireless communication function and a sensor function. This IoT device 100 transmits a measurement result obtained by a sensor by wireless communication. Note that the IoT device 100 is an exemplary sensing device described in the claims.
The base station 300 is a base station that performs wireless communication with the IoT device 100. This base station 300 performs wireless communication with the IoT device 100 installed within a communication range 301. This base station 300 connects to the server 500 via the network 400, and transmits the measurement result from the IoT device 100 to the server 500.
The server 500 is a server that holds the measurement result from the IoT device 100. This server 500 connects the IoT device 100 via the network 400, and receives and holds the measurement result from the IoT device 100.
The device management apparatus 200 is a device that manages the IoT device 100. As will be described later, the device management apparatus 200 gives an instruction for selection or deselection of the IoT device 100, receives a notification from the IoT device 100, and creates a device list for managing the IoT device 100 on the basis of the notification.
[IoT Device]
This IoT device 100 includes a selection-acceptance-state changing unit 110, a selection-acceptance-state holding unit 120, a selection-state-information holding unit 130, a sensor 140, a selection control unit 150, an identification-information holding unit 160, and a notification unit 170.
The selection-acceptance-state holding unit 120 holds a selection-acceptance state indicating whether or not the IoT device 100 is in a state of accepting a change of the selection state. This selection-acceptance-state holding unit 120 holds a “selectable state” if the IoT device 100 is in the state of accepting a change of the selection state, or holds a “non-selectable state” if the IoT device 100 is in a state of not accepting a change of the selection state.
The selection-acceptance-state changing unit 110 changes the selection-acceptance state held in the selection-acceptance-state holding unit 120. The selection-acceptance state is a concept provided in terms of security, and in the case of changing the selection state, it is assumed that an authorized person sets in advance the selection-acceptance state to the “selectable state”. This setting can prevent a selection of the IoT device 100 against the intention of the authorized person. Therefore, under an environment where security is guaranteed by another approach, a secure mechanism by the selection-acceptance-state holding unit 120 and the selection-acceptance-state changing unit 110 may not be provided. Note that the function of this selection-acceptance-state changing unit 110 may be achieved with the sensor 140 and the selection control unit 150 as described later.
The selection-state-information holding unit 130 holds selection-state information indicating whether or not this IoT device 100 is in the selected state. The selection-state-information holding unit 130 holds the “selected state” if the IoT device 100 is in the selected state, or holds the “non-selected state” if not selected.
The sensor 140 measures the ambient environment by sensing operation to generate a measurement signal. This sensor 140 has a sensing function for measuring, for example, radio waves including visible light, infrared rays, and the like; sound waves; vibrations; and the like, and more specifically, an optical sensor, a vibration sensor, or the like is assumed.
In the present embodiment, the sensor 140 has a function as a selection accepting unit. That is, the selection of the IoT device 100 is accepted with the sensor 140 having a normal sensing function without separately providing a special mechanism for accepting the selection of the IoT device 100. This arrangement simplifies the configuration of the IoT device 100 and contributes to saving for power consumption. Note that this sensor 140 may accept not only an instruction for selection but also an instruction for deselection.
The selection control unit 150 controls the selection state of the IoT device 100. In a case where the measurement signal from the sensor 140 gives an instruction for selection of the IoT device 100, the selection control unit 150 causes the selection-state information held in the selection-state-information holding unit 130 to transition to the “selected state”. On the other hand, in a case where the measurement signal from the sensor 140 gives an instruction for deselection of the IoT device 100, the selection control unit 150 causes the selection-state information held in the selection-state-information holding unit 130 to transition to the “non-selected state”. However, in a case where the selection-acceptance state held in the selection-acceptance-state holding unit 120 indicates the “non-selectable state”, these pieces of selection-state information cannot be changed. Note that in a case where the same state is indicated before and after transition, the same state may be overwritten, or nothing may be written.
In addition, in a case where the sensor 140 does not accept the selection of the IoT device 100 even after the elapse of a certain period of time since the selection-acceptance-state changing unit 110 has changed the selection-acceptance state to the “selectable state”, the selection-acceptance state may be caused to transition to the “non-selectable state” in view of security.
The identification-information holding unit 160 holds identification information for identifying the IoT device 100. As this identification information, a device-unique identifier uniquely assigned such that the IoT device 100 can be specified distinctively, a device-type identifier representing the type (device type) of the IoT device 100, and the like are assumed.
The notification unit 170 notifies the device management apparatus 200 that the IoT device 100 has been selected, in a case where the selection-state information held in the selection-state-information holding unit 130 is the “selected state”. This notification unit 170 has, for example, a wireless communication function, and transmits a notification to the device management apparatus 200 by wireless communication. When issuing the notification that the IoT device 100 has been selected, the notification unit 170 also issues a notification of the identification information for the IoT device 100. This notification allows the device management apparatus 200 to grasp the information regarding the selected IoT device 100.
[Device Management Apparatus]
This device management apparatus 200 includes a selection-acceptance-state changing instruction unit 210, a device-selection instruction unit 220, a device-selection-notification receiving unit 230, a device-list holding unit 240, and a management control unit 250.
The selection-acceptance-state changing instruction unit 210 instructs at least part of the plurality of IoT devices 100 of changing the corresponding selection-acceptance state. This instruction is received by the selection-acceptance-state changing unit 110 of the IoT device 100, and the selection-acceptance state held in the selection-acceptance-state holding unit 120 is changed in response to the notification.
Note that, as described above, the selection-acceptance state is provided in view of security, and thus under an environment where security is guaranteed by another approach, the secure mechanism by the selection-acceptance-state changing instruction unit 210 may not be provided. In addition, there will be described the example in which the device management apparatus 200 includes the selection-acceptance-state changing instruction unit 210; however, the selection-acceptance state may be changed by an apparatus different from the device management apparatus 200.
The device-selection instruction unit 220 instructs at least part of the plurality of IoT devices 100 to select the corresponding IoT device 100. This instruction is sensed by the sensor 140 of the IoT device 100, and the selection-state information held in the selection-state-information holding unit 130 is set by the selection control unit 150 in response to the measurement signal. Thus, it is assumed that as an instruction by the device-selection instruction unit 220, for example, radio waves including visible light, infrared rays, and the like; sound waves; vibrations; or the like can be used in accordance with the sensing function of the sensor 140. Note that the device-selection instruction unit 220 may instruct the IoT device 100 not only to make a selection but also to make a deselection.
The device-selection-notification receiving unit 230 receives a notification from the IoT device 100 in response to the selection instruction. This notification is a notification issued by the notification unit 170 of the IoT device 100 in a case where the selection-state information of the IoT device 100 is the “selected state”. This notification includes identification information for the IoT device 100, which allows the device management apparatus 200 to grasp the information regarding the selected IoT device 100.
The management control unit 250 controls each unit of the device management apparatus 200. That is, this management control unit 250 controls an instruction for changing the selection-acceptance state of the IoT device 100, an instruction for selecting the IoT device 100, and the like.
The device-list holding unit 240 holds a device list that is a list of IoT devices 100 each of which selection-state information is “selected state”. This device list is created by the management control unit 250 on the basis of the notification received by the device-selection-notification receiving unit 230.
This device list includes fields of a format identifier 241, a device-type identifier 242, a device-unique identifier 243, a belonging-group identifier 244, time information 245, and additional information 246.
The format identifier 241 is information with which the identification information transmitted by the IoT device 100 can be recognized.
The device-type identifier 242 is information indicating the device type of the IoT device 100.
The device-unique identifier 243 is information with which the IoT device 100 can be specified distinctively. As the device-unique identifier 243, for example, there can be used a media access control (MAC) address of a network interface card (NIC) or a Bluetooth device (BD) address of Bluetooth (registered trademark). Furthermore, values obtained by converting these addresses in accordance with a certain rule may be used.
The belonging-group identifier 244 is information indicating a group selected as the IoT device 100. That is, as described later, each IoT device 100 may be selected on a group basis, and in that case, the IoT device 100 may be selected across a plurality of groups. Thus, it is assumed that a bit field corresponding to each group is provided and that selection or non-selection is expressed in binary form for the group to which the IoT device 100 belongs.
The time information 245 is information indicating the time when the IoT device 100 has been selected or the time when the selection state has been changed.
The additional information 246 is a field for storing other information, and is information that can be appropriately used by an application.
<2. Operation>
[IoT Device]
First, the selection control unit 150 stands by until the sensor 140 receives a selection instruction from the device-selection instruction unit 220 of the device management apparatus 200 (step S911: No). In a case where the selection instruction has been received (step S911: Yes), the selection control unit 150 performs the following selection operation. However, even in the case of receiving the selection instruction, in a case where a deselection instruction has been further received (step S912: Yes), the selection-state information held in the selection-state-information holding unit 130 is set to the “non-selected state” (step S916).
In a case where no deselection instruction has been received (step S912: No), if the selection-acceptance state held in the selection-acceptance-state holding unit 120 indicates the “selectable state” (step S913: Yes), the selection-state information is set to the “selected state” (step S914). Then, the notification unit 170 notifies the device management apparatus 200 that the IoT device 100 has been selected (step S915). On the other hand, if the selection-acceptance state held in the selection-acceptance-state holding unit 120 indicates the “non-selectable state” (step S913: No), the processing ends without changing the selection-state information.
[Device Management Apparatus]
The device-selection instruction unit 220 instructs the selection target among the plurality of IoT devices 100 to select the corresponding IoT device 100 (step S921). Thereafter, the device-selection instruction unit 220 stands by until the notification that the selection has been made is received from the IoT device 100 to which the selection instruction has been given (step S922: No).
Then, after receiving the notification that the selection has been made from the IoT device 100 (step S922: Yes), the management control unit 250 creates a device list on the basis of the notification and records the device list in the device-list holding unit 240 (step S923).
[Overall Processing]
The selection-acceptance-state changing instruction unit 210 instructs the IoT device 100 to make a transition of its selection-acceptance state to the “selectable state” (811). The selection-acceptance-state changing unit 110 causes the selection-acceptance state held in the selection-acceptance-state holding unit 120 to transition to the “selectable state” (812).
Thereafter, the device-selection instruction unit 220 instructs the IoT device 100 to select the IoT device 100 (813). In response to sensing of the instruction by the sensor 140, the selection control unit 150 causes the selection-state information held in the selection-state-information holding unit 130 to transition to the “selected state” and instructs the notification unit 170 to issue a notification that the selection has been made (814). In response to the instruction, the notification unit 170 reads the identification information from the identification-information holding unit 160 (815) and notifies the device management apparatus 200 (816).
Thereafter, the selection-acceptance-state changing instruction unit 210 instructs the IoT device 100 to make a transition of its selection-acceptance state to the “non-selectable state” (821). The selection-acceptance-state changing unit 110 causes the selection-acceptance state held in the selection-acceptance-state holding unit 120 to transition to the “non-selectable state” (829).
[Modification]
In this modification, similarly to the above example, the selection-acceptance-state changing instruction unit 210 instructs an IoT device 100 to make a transition of its selection-acceptance state to the “selectable state” (811). Thereafter, the subsequent processing is performed similarly to the above example until the notification unit 170 reads the identification information from the identification-information holding unit 160 (815).
Thereafter, the selection-acceptance-state changing instruction unit 210 instructs the IoT device 100 to make a transition of its selection-acceptance state to the “non-selectable state” (821), and when the instruction for the transition is noticed to the selection control unit 150, a notification is issued at this timing (822). That is, the notification unit 170 notifies the device management apparatus 200 (823) of the identification information read from the identification-information holding unit 160 (815). Then, the selection-acceptance-state changing unit 110 causes the selection-acceptance state held in the selection-acceptance-state holding unit 120 to the “non-selectable state” (829).
<3. Selection Mode>
[Selection and Deselection]
This example illustrates that, as the device-selection instruction unit 220, a lighting that emits visible light is used with assumption that the sensor 140 of each IoT device 100 serves as an optical sensor. Even in a case where a large number of IoT devices 100 are installed scatteringly in an area, if visible light enables selection and deselection, an IoT device group depending on a purpose can be selected within a range of irradiation with the visible light. Note that in the following example, it is assumed that the selection-acceptance state of the IoT device 100 is the “selectable state”.
In this example, visible light that gives an instruction for selection is emitted from the device-selection instruction unit 220, and an area 221 including part of the plurality of IoT devices 100 is irradiated with the visible light. This irradiation causes the selection-state information of an IoT device 101 present in the area 221 to transition to the “selected state”.
In this example, visible light that gives an instruction for deselection is emitted from the device-selection instruction unit 220, and an area 222 including part of the plurality of IoT devices 100 is irradiated with the visible light. This irradiation causes the selection-state information of an IoT device 102 present in the area 222 to transition to the “non-selected state”.
As a result, the selection-state information of the IoT device 101 present in the area 221 and not present in the area 222 becomes the “selected state”, and a notification of the identification information is issued at a predetermined later timing.
[Group]
Each IoT device 100 may be selected on a group basis. In this case, the IoT device 100 may be selected across a plurality of groups.
In this example, visible light that gives an instruction for selection of the group A is emitted from the device-selection instruction unit 220, and an area 223 including part of the plurality of IoT devices 100 is irradiated with the visible light. This irradiation causes, as the group A, the selection-state information of an IoT device 103 present in the area 223 to transition to the “selected state”.
In this example, visible light that gives an instruction for selection of the group B is emitted from the device-selection instruction unit 220, and an area 224 including part of the plurality of IoT devices 100 is irradiated with the visible light. The visible light having given the instruction for the selection of the group B is different from the visible light having given the instruction for the selection of the group A. Thus, as the group B, the selection-state information of an IoT device 104 present in the area 224 transitions to the “selected state”. However, an IoT device 105 present in the area 224 and having already been selected as the group A has been selected across the group A and the group B.
A notification of the groups to which each of the IoT devices 103 to 105 belongs are issued by the corresponding notification unit 170. After receiving this notification, the management control unit 250 of the device management apparatus 200 stores each of the groups in the device-list holding unit 240 as a bit field corresponding to the group, in the belonging-group identifier 244 of the device list. As a result, the device management apparatus 200 can manage the IoT devices 100 for each group.
[Discrimination with Color]
In this example, an IoT device 106 that recognizes as having been selected by irradiation with red light and an IoT device 107 that recognizes as having been selected by irradiation with blue light are disposed mixedly. In this case, if visible light having different wavelengths enables selection, an IoT device group depending on a purpose can be selected.
In this example, the irradiation with the red light from the device-selection instruction unit 220 causes the IoT device 106 to recognize that the IoT device 106 itself has been selected. As a result, the selection-state information of the IoT device 106 transitions to the “selected state”.
In this example, the irradiation with the blue light from the device-selection instruction unit 220 causes the IoT device 107 to recognize that the IoT device 107 itself has been selected. As a result, the selection-state information of the IoT device 107 transitions to the “selected state”.
Note that in these examples, the operation of selection and deselection has been described assuming the optical sensor serving as the sensor 140; however, the sensor 140 may be another type of sensor. For example, in the case of an IoT device 100 having a vibration sensor that serves as the sensor 140, selection and deselection may be made in response to the sound of applause.
As described above, according to the embodiment of the present technology, the selection (and deselection) of an IoT device 100 can be accepted with the sensor 140 having a normal sensing function, without separately providing a special mechanism for accepting the selection of the IoT device 100. The selected IoT device 100 notifies the device management apparatus 200 of the identification information, with the notification unit 170. As a result, the device management apparatus 200 can generate a device list of the IoT device 100 in an installation state. That is, there is no need of creating and managing a management ledger for an individual IoT device 100 before operation, and even in a case where the disposition of the IoT device 100 is changed after the start of operation, flexible management can be performed in the latest installation state.

Similarly, the matters specifying the invention in the claims and the matters having the same names in the embodiment of the present technology have a correspondence relationship.

Furthermore, the processing procedures described in the above embodiment may be regarded as a method including these series of procedures, or as a program for causing a computer to execute the series of procedures or as a recording medium that stores the program. As this recording medium, there can be used, for example, a compact disc (CD), a mini disc (MD), a digital versatile disc (DVD), a memory card, a Blu-ray (registered trademark) disc, or the like.
