Collecting a wide variety of types of data comprehensively and analyzing the wide variety of types of data enable more advanced control, a more accurate malfunction diagnosis, or the like. However, conventional techniques such as the aforementioned technique are not devised for efficiently collecting a wide variety of types of data.

The processor 11 includes a central processing unit (CPU). The processor 11 executes a program stored in the auxiliary storage 13, thereby achieving various functions of the data collection apparatus 100.
The main storage 12 includes a random access memory (RAM). The program is loaded from the auxiliary storage 13 into the main storage 12. The main storage 12 is used by the processor 11 as a work area.
The auxiliary storage 13 includes a nonvolatile memory such as an electrically erasable programmable read-only memory (EEPROM). The auxiliary storage 13 stores the program and various types of data used for processing by the processor 11.

The processor 21, the main storage 22, the auxiliary storage 23, the communicator 24, the inputter 25, the outputter 26, and the RTC 27 have respective functions that are similar to those of the processor 11, the main storage 12, the auxiliary storage 13, the communicator 14, the inputter 15, the outputter 16, and the RTC 17.
Next, functions of the data collection apparatus 100 and the control apparatus 200 are described with reference to
The collector 101 collects the operation data indicating an operation status of the air conditioning system 300. The collector 101 is achieved by cooperation between the processor 11 and the communicator 14. The collector 101 is an example of collection means.
The operation data is data indicating the operation status of the air conditioning system 300. The operation data includes dynamic data that changes over time and static data that remains static over time. The dynamic data is, for example, information relating to (i) a remote-controller set value such as a temperature setting, a wind direction, and a wind velocity, (ii) a value of the sensor included in the air conditioner 310, and (iii) an operating time, an operation mode, presence/absence of abnormality, and content of control of the air conditioner 310. The static data is, for example, information of a device model of the air conditioner 310 and information of a system scale of the air conditioning system 300. The information of the system scale is, for example, information of a number of the indoor units 311 included in the air conditioning system 300 and a number of the outdoor units 312 included in the air conditioning system 300. In the present embodiment, the dynamic data included in the operation data is taken to be time-series data at one-minute intervals.
The collector 101 collects the operation data from each of the air conditioning systems 300, for example, periodically at one-hour intervals. That is to say, the collector 101 collects, together every one hour, the operation data including the time-series data at one-minute intervals. The intervals at which the collection is performed are freely determined by a manager of the data collection apparatus 100. The static data included in the operation data is not necessarily collected periodically and may be collected just at predetermined timings. For example, the collector 101 may collect the static data at a time of startup of the air conditioner 310.
The collector 101 transmits the collected operation data to the control apparatus 200 that is described later. Further, the collector 101 registers the collected operation data in the operation data storage 102 after the evaluator 103 that is described later calculates the evaluation value for the collected operation data.
The operation data storage 102 stores the operation data of each of the air conditioning systems 300 to which a service of remote control is provided by the remote control system 1. The operation data storage 102 is achieved by the auxiliary storage 13. The operation data storage 102 is an example of storage means.
The temperature sensor value is, for example, an inlet temperature that is a temperature of air drawn through an inlet of the one or more the indoor units 311. The pressure sensor value is, for example, a value of a pressure of a refrigerant flowing through piping of the one or more outdoor units 312.
The used function is a function relating to control of the air conditioner 310 of the air conditioning system 300 and is a function that enables achievement of energy conservation. For example, “normal” indicates a control state in which no special control for achievement of energy conservation is performed. The “function A” indicates, for example, evaporation temperature control that is control of a temperature in an evaporator for suppressing electric power consumption in response to approach to a set temperature. The “function B” indicates, for example, rotation control that is control in which multiple indoor units 311 are regarded as one group and operations of the indoor units of the group are sequentially switched such that at least one indoor unit of the indoor units of the group operates to suppress electric power consumption by, for example, stopping operation or performing ventilation.
The abnormality code is a code associated with content of an abnormality that may possibly occur in the air conditioning system 300. Here “absent” as the abnormality code indicates that no abnormality occurs in the air conditioning system 300. The “code A” indicates, for example, leakage of refrigerant in the one or more outdoor units 312.
The electric power consumption amount indicates an amount of electric power consumed by the air conditioner 310 during a predetermined unit period. In the present embodiment, the unit period is one minute, and the electric power consumption amount in the present embodiment is an electric power amount measured in one minute immediately before the date and time of measurement of the operation data.
The record in the first line of the table of
The evaluator 103 of
The evaluation of the operation data is freely determined by the manager of the remote control system 1, for example, by the determination method “the evaluation of the operation data is higher as a degree to which the manager desires to acquire the operation data” is higher. In the present embodiment, (i) as rarity of operation data is higher, that is, as an amount of the operation data stored in the operation data storage 102 is smaller, a degree to which the manager desires to acquire operation data of the same type as the operation data is taken to be higher, and (ii) such operation data is taken to have a high evaluation. For example, a distribution of the operation data is obtained with respect to a predetermined evaluation item, and operation data belonging to the same class are regarded as being of the same type.
The evaluator 103 obtains a distribution of the stored operation data with respect to the predetermined evaluation item, and calculates for the collected operation data an evaluation value that is higher as an amount of the operation data included in the class of the obtained distribution to which the collected operation data belongs is smaller. The amount of the operation data is represented by, for example, a data amount such as a number of samples or bytes. Hereinafter, the amount of the stored operation data is called the “accumulation amount”, and the accumulation amount is represented by the number of samples.
A method performed by the evaluator 103 for calculating the evaluation value is specifically described. The evaluator 103 firstly obtains, for the collected operation data, values with respect to predetermined evaluation items. The evaluation items are, for example, the operating time, the device model, the system scale, the abnormality code, and the used function.
If the collector 101 is taken to have collected from the air conditioning system 300 corresponding to the air conditioning system ID “0001” the operation data from 8:00 to 9:00 on Mar. 7, 2020, the evaluator 103 obtains, with respect to the evaluation item “operating time”, an accumulated operating time from the date and time of construction of the air conditioning system 300 corresponding to the air conditioning system ID “0001” to 9:00 on Mar. 7, 2020. With respect to the evaluation item “device model”, the evaluator 103 obtains a device model number indicating a device model of the air conditioner 310 included in the air conditioning system 300 corresponding to the air conditioning system ID “0001”. With respect to the evaluation item “system scale”, the evaluator 103 obtains a number of the one or more indoor units 311 included in the air conditioning system 300 corresponding to the air conditioning system ID “0001” and a number of the one or more outdoor units 312 included in the air conditioning system 300 corresponding to the air conditioning system ID “0001”. With respect to the evaluation item “abnormality code”, the evaluator 103 obtains an abnormality code included in the operation data from 8:00 to 9:00 on Mar. 7, 2020. With respect to the evaluation item “used function”, the evaluator 103 obtains a value of a used function included in the operation data from 8:00 to 9:00 on Mar. 7, 2020.
Then the evaluator 103 obtains distributions of the operation data of the other air conditioning systems 300 stored in the operation data storage 102 with respect to the evaluation items. For example, with respect to the evaluation item “operating time”, the evaluator 103 obtains operating times of the other air conditioning systems 300 and obtains a histogram as illustrated in
Then the evaluator 103 calculates, for each of the evaluation items, an evaluation value i based on Formula 1 below.
Evaluation value i=1.0−Xi/Yi (Formula 1)
The evaluation value obtained by Formula 1 above is closer to 1 as the number of samples in the class to which the collected operation data belongs is smaller. That is to say, the evaluation value obtained for the collected operation data is higher as the accumulation amount of the operation data that can be deemed as being of the same type as the collected operation data is smaller.
The determiner 104 determines, based on the evaluation values, compensation for provision of the collected operation data. The determiner 104 is achieved by the processor 11. The determiner 104 is an example of determination means.
The compensation is a reward given for a provider of the collected operation data as a reward for the provision. The provider of the operation data is typically an owner of the air conditioning system 300 that receives a remote control service. In the explanation below, the compensation is taken to be an evaluation point that can be used to discount a service utilization charge for the remote control system. The evaluation point is, for example, an average value of the evaluation values i obtained for the evaluation items. Upon determining the evaluation point based on the average value of the evaluation values i, the determiner 104 registers the determined point in a table stored in a utilization data storage 202 of the control apparatus 200 that is described later.
The presenter 105 presents the determined compensation to the provider of the collected operation data. The presenter 105 is achieved by the processor 11. The presenter 105 is an example of presentation means.
If, for example, the operation data from 8:00 to 9:00 on Mar. 7, 2020, is collected from the air conditioning system 300 corresponding to the air conditioning system ID “0001”, the presenter 105 sends, to the connection terminal 330 in the air conditioning system 300 corresponding to the air conditioning system ID “0001”, a message including a value of the evaluation point.
Next, functions of the control apparatus 200 are described with reference to
The controller 201 executes remote control of the air conditioning systems 300 based on the collected operation data. The controller 201 is achieved by cooperation between the processor 21 and the communicator 24. The controller 201 is an example of control means.
The controller 201 includes a control executor 211 that executes control of the air conditioners 310 of the air conditioning systems 300, and a malfunction diagnoser 212 that performs a malfunction diagnosis of the air conditioning systems 300. The control executor 211, for example, predicts a demand electric power of the next day based on the operation data stored in the operation data storage 102 and executes control for electric-load leveling based on the predicted demand electric power and the collected operation data. The malfunction diagnoser 212, for example, diagnoses that a sign of malfunction is found in response to a high similarity between (i) the collected operation data and (ii) the operation data that is from other real-estate properties in which a malfunction occurs previously and that is data before occurrence of the malfunction.
Further, the controller 201 registers, in the utilization data storage 202, information of a time at which the service of the remote control is provided.
The utilization data storage 202 stores utilization data relating to the service for the multiple air conditioning systems 300. The utilization data storage 202 is achieved by the auxiliary storage 23.
The utilization data is data indicating statuses of utilization of the service by the air conditioning systems 300. The utilization data includes, for example, a utilization time of the service, a utilization charge for the service, and the evaluation point.
The first line of the table of
The information relating to the remote control is, for example, information relating to the content of control executed by the control executor 211 and a result of the malfunction diagnosis. Further, the information relating to the remote control includes a value of cost that is required for execution of the remote control and that is obtained with reference to compensation for provision of data. The value of cost that is required for execution of the remote control and that is obtained with reference to compensation is, for example, a value of a billing amount obtained by deducting the evaluation point from the service utilization charge. The notifier 203 obtains the billing amount with reference to the items of the utilization charge and the evaluation point in the table of
Next, processing executed by the data collection apparatus 100 and the control apparatus 200 of the remote control system 1 according to the present embodiment is described with reference to flowcharts.
First, data collection processing executed by the data collection apparatus 100 is described with reference to the flowchart of
The collector 101 collects the operation data from the air conditioning system 300 (step S101). The evaluator 103 obtains a value of the collected operation data with respect to a predetermined evaluation item (step S102). Then the evaluator 103 obtains a distribution of the operation data of the air conditioning system 300 stored in the operation data storage 102 with respect to the evaluation item (step S103). Then the evaluator 103 calculates an evaluation value based on a class of the distribution of the stored operation data with respect to the evaluation item to which the value of the collected operation data with respect to the evaluation item belongs (step S104).
The determiner 104 determines an evaluation point based on the evaluation value (step S105). The presenter 105 presents the determined point to the provider of the collected operation data (step S106).
Next, control processing executed by the control apparatus 200 is described with reference to the flowchart of
The control executor 211 transmits, based on the collected operation data, to the air conditioning system 300, information indicating content of control in the next period (step S201). The malfunction diagnoser 212 performs a malfunction diagnosis of the collected operation data (step S202).
The notifier 203 obtains the billing amount per the utilization time based on the utilization data stored in the utilization data storage 202 (step S203). Then the notifier 203 sends, to the provider of the operation data, notification of the information relating to the remote control and including the billing amount (step S204).
According to the present embodiment, compensation for provision of the collected operation data is determined based on an evaluation of the collected operation data, and the determined compensation is presented to the provider of the collected operation data. This enables prompting of the provision of the operation data, enabling prompt collection of a wide variety of types of data. Further, high compensation is determined for data that the manager of the remote control system desires to acquire whereas low compensation is determined for data for which acquisition is not as much desired by the manager, thereby enabling cost that is lower than in a case in which fixed compensation is given for any data collection. Thus, according to the present embodiment, collection of a wide variety of types of data that is efficient in view of time and cost can be performed.
For example, in a case in which data is evaluated to have an evaluation that is higher as the accumulation amount of the operation data in the remote control system is smaller, high compensation is paid for provision of data during a period shortly after the start of operation of the remote control system, since the amount of data accumulated in the remoted control system is small during this period. In contrast, after the amount of accumulated data is large through operation by the remote control system for a long period of time after the start of operation, low compensation is paid for provision of data. This configuration enables prompting a customer who enjoys a service of the remote control system to provide data during a period shortly after the start of operation of the remote control system, thus enabling prompt collection of data. Further, the customer who utilizes the remote control system can utilize the service at a low price during the period shortly after start of operation of the remote control system.
Furthermore, according to the aforementioned embodiment, in a case in which, for example, the manager of the remote control system desires to acquire the operation data of a particular device model, a formula is settable by which the evaluation value is calculated such that a high evaluation value is obtained for the operation data of this device model. For example, in a case in which acquisition of the operation data from an air conditioning system including an air conditioner of a device model for a cold weather region is desired, high compensation is given for provision of such operation data. Although an amount of data collectable from a cold weather region is small since a number of air conditioning systems in such a region is small due to sparse population, giving high compensation enables prompting a customer to provide data, enabling collecting a larger amount of data promptly.
Furthermore, according to the present embodiment, compensation for provision of data collected on a large scale can be automatically calculated and presented, thereby eliminating the need for analyzing the collected data by humans, and accordingly enabling low operational cost.
Furthermore, a wide variety of types of data is collectable in the remote control system according to the present embodiment, and thus using such types of data enables improving quality of service. Further, collecting a wide variety of types of data by using the data collection apparatus according to the present embodiment enables performing a high-accuracy market analysis based on the collected data, enabling development of a product having a high added value for customers.
A remote control system 1 according to Embodiment 2 is a system that collects additional data in addition to the operation data.
The remote control system 1 according to Embodiment 2 includes a data collection apparatus 100 and a control apparatus 200. The control apparatus 200 of Embodiment 2 has functions that are similar to those of the control apparatus 200 of Embodiment 1. The data collection apparatus 100 of Embodiment 2 has functions described below, in addition to the functions of the data collection apparatus 100 of Embodiment 1.
The functions of the data collection apparatus 100 of the present embodiment are described with reference to
The receiver 106 receives input of the additional data. The receiver 106 is achieved by cooperation between the processor 11 and the communicator 14. The receiver 106 is an example of receiving means.
The additional data is data to be associated with the operation data and is data that cannot be collected automatically from a facility device system as a remote control target, that is, cannot be collected in the manner of collecting the operation data. That is to say, the additional data is data that is unavailable without being input from the exterior. The input from the exterior may be performed manually or automatically. The additional data is, for example, an installation location of the air conditioner 310, building information of a building in which the air conditioning system 300 is constructed, and a use application of the air conditioning system 300. Examples of the installation location include an arrangement of indoor units within a floor, and an installation location of outdoor units. The installation location of the outdoor units is, for example, a location such as a roof, a veranda, and the ground. The building information includes an age, a size, an insulation performance, a piping length, a location and orientation of a window, or the like. The building information may be building information modeling (BIM) data. The use application is, for example, an item indicating an office, a shop, a hospital, or the like.
The receiver 106, upon receiving the input of the additional data, registers the additional data in the operation data storage 102 in association with the operation data. For example, in a case of receiving input of the building information of a real-estate property in which the air conditioning system 300 corresponding to the air conditioning system ID “0001” is constructed, the receiver 106 registers the inputted building information in the operation data storage 102 in association with the operation data of the air conditioning system 300 corresponding to the air conditioning system ID “0001”.
For example, the first line of the table of
The classifier 107 classifies the operation data stored in the operation data storage 102 into one or more groups based on the values the operation data stored in the operation data storage 102. The classifier 107 performs the classification upon the determiner 104 determining that the additional data is added to the collected operation data. The classifier 107 is achieved by the processor 11. The classifier 107 is an example of classification means.
For example, clustering that is an example of unsupervised learning is employed to perform the classification of the operation data. Hereinafter, classification by employment of k-means clustering is described. Clusters obtained through the classification are taken to be the aforementioned “groups”. First, the operation data stored in the operation data storage 102 is divided into data pieces that each are a data piece per unit time. Thereafter, evaluation items used for the classification are determined. In the present embodiment, the unit time is taken to be one hour, and the classification is performed based on the temperature sensor value and the pressure sensor value. Since the operation data is data measured every one minute, each of the data pieces obtained through the dividing by the unit time is representable by a multidimensional vector having dimensions of 60 (a number of pieces of measured data)×2 (the temperature sensor value and the pressure sensor value).
For example, in the case in which the operation data storage 102 stores the operation data of the air conditioning system 300 corresponding to the air conditioning system ID “0002” for 1,000 hours, the air conditioning system 300 corresponding to the air conditioning system ID “0002” has 1,000 multidimensional vectors. As described above, the air conditioning system 300 has multiple multidimensional vectors for the operation data. The classifier 107 performs clustering of all of multidimensional vectors that all of the air conditioning systems 300 have and that are stored in the operation data storage 102.
Then the determiner 104 determines, from among the one or more groups obtained through the classification, a group to which the collected operation data belongs.
For example, the determiner 104 (i) calculates a distance between each of vectors of centroids of k clusters obtained by the k-means method and a vector indicating the collected operation data and (ii) determines a cluster having a centroid of which vector defines the shortest distance from the vector indicating the collected operation data to be the cluster to which the collected operation data belongs.
The determiner 104 obtains, for the pieces of the operation data included in the cluster determined to be the cluster to which the collected operation data belongs, an appending rate that is a rate of appending of the additional data. The appending rate is a ratio, to all of the pieces of the operation data included in the determined cluster, of pieces of the operation data to which the additional data is appended.
Then the determiner 104 corrects the compensation based on the appending rate, more specifically, obtains a corrected evaluation point based on Formula 2 below.
Corrected evaluation point=1.0−Appending rate×(1.0−Evaluation point) (Formula 2)
The corrected evaluation point obtained by Formula 2 above is closer to the evaluation point determined based on the accumulation amount of the operation data as the appending rate is higher, that is, as a rate of appending of the additional data to the pieces of the operation data included in the cluster to which the collected operation data belongs is higher. In contrast, the corrected evaluation point is higher as the rate of appending of the additional data to the pieces of the operation data included in the cluster to which the collected operation data belongs is lower. For example, the evaluation point corrected by Formula (2) above is, in the case in which the appending rate is 100%, a value that is the same as the evaluation point determined based on the accumulation amount of the operation data. In contrast, in the case in which the appending rate is 0%, the evaluation point is 1.
The presenter 105 presents the corrected evaluation point to the provider of the collected operation data. For example, in a case in which (i) the operation data from 8:00 to 9:00 on Mar. 7, 2020, is collected from the air conditioning system 300 corresponding to the air conditioning system ID “0001” and (ii) the additional data is appended to the collected operation data, the presenter 105 sends, to the connection terminal 330 in the air conditioning system 300 corresponding to the air conditioning system ID “0001”, a message including a value of the corrected evaluation point.
Next, data collection processing executed by the data collection apparatus 100 of the present embodiment is described with reference to the flowchart of
The processing in steps S301-S305 is similar to the processing of steps S101-S105 in the flowchart of
The determiner 104 determines whether the additional data is appended to the collected operation data (step S306). Upon the determiner 104 determining that the additional data is appended to the collected operation data (YES in step S306), the classifier 107 classifies the operation data stored in the operation data storage 102 into multiple clusters based on the values of the operation data (step S307). Conversely, upon the determiner 104 determining that the additional data is not appended to the collected operation data (NO in step S306), the processing proceeds to step S310 and the presenter 105 presents the evaluation point obtained in step S305 (step S310).
Upon the operation data stored in the operation data storage 102 being classified into multiple clusters in step S307, the determiner 104 determines, based on a value of the collected operation data, from among the clusters obtained through the classification, a cluster to which the collected operation data belongs (step S308). The determiner 104 obtains the appending rate that is a rate of addition of the additional data to the operation data included in the determined cluster, and corrects the evaluation point based on the appending rate (step S309). Then the presenter 105 presents the corrected evaluation point (step S310).
According to the present embodiment, upon the collected operation data being operation data that belongs to a group in which a ratio of the operation data to which the additional data is appended is low and being operation data to which the additional data is appended, high compensation is determined for provision of the collected operation data. This configuration enables prompting appending of the additional data, enabling efficient collection of the additional data that is difficult to acquire automatically from the system.
Modified Examples
The aforementioned embodiments of the present disclosure may be modified and applied in various manners.
Although the data collection apparatus 100 and the control apparatus 200 of the aforementioned embodiments are taken to be connected via a network, this configuration is not limiting. One apparatus may double as the data collection apparatus 100 and the control apparatus 200. Further, a part or all of the elements included in the data collection apparatus 100 and the control apparatus 200 may be provided on a cloud server.
Although the evaluator 103 of the aforementioned embodiments obtains a distribution of the operation data with respect to each single evaluation item such as “operating time”, such a distribution may be obtained with respect to a combination of multiple evaluation items. For example, a histogram may be obtained in which classes are set based on an item that is a combination of the “device model” and the “abnormality code”. Further, for example, the accumulation amount of the operation data in an air conditioning system constructed in a general office is large whereas the accumulation amount of the operation data in an air conditioning system constructed in a general hospital ward is small. In such a case, creating a class representing a characteristic of hospital wards by combining multiple evaluation items enables efficiently collecting the operation data from hospital wards.
Furthermore, although the compensation is taken to be the evaluation point that can be used to discount a service utilization charge in the explanation in the aforementioned embodiments, the compensation is not limited thereto and may be, for example, cash, a ticket for a free on-site service in a case of malfunction, or a right to enjoy a more expensive remote control service.
Furthermore, although the evaluation point is corrected based only on the appending rate of the additional data only in the aforementioned embodiment, this configuration is not limiting, and a correction amount of the evaluation point may be changed according to a type of the additional data. For example, the correction amount is changed based on a utility value of the additional data, a degree of difficulty in acquiring the additional data, or the like. Specifically, for the operation data to which data that affects efficiency of an air conditioner, such as data relating to an insulation performance of a real-estate property, is appended, correction is performed such as heightening of the value of the evaluation point. Additionally, for the operation data to which data that changes depending on a status of use of a real-estate property, such as data of a number of residents in the real-estate property and a number of uses of the real-estate property, is appended, correction is performed such as heightening of the value of the evaluation point. This configuration enables defining the compensation according to a type of the additional data, enabling cost of compensation for the additional data that is lower than in a case in which fixed compensation is paid for any additional data.
Furthermore, although the data collection processing of
Furthermore, the order of steps in the control processing executed by the control apparatus 200 in the aforementioned embodiments is not limited to the order of
Furthermore, applying to an existing personal computer or to an existing information terminal device an operation program defining operations of the data collection apparatus 100 and the control apparatus 200 according to the aforementioned embodiments can allow the personal computer or the information terminal device to function as the data collection apparatus 100 and the control apparatus 200 according to the aforementioned embodiments.
Furthermore, such a program may be distributed by any method, for example, may be distributed by storing the program in a computer-readable recording medium, such as a compact disk read only memory (CD-ROM), a digital versatile disk (DVD) and a memory card, or may be distributed via a communication network such as the Internet.
The foregoing describes some example embodiments for explanatory purposes. Although the foregoing discussion has presented specific embodiments, persons skilled in the art will recognize that changes may be made in form and detail without departing from the broader spirit and scope of the invention. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. This detailed description, therefore, is not to be taken in a limiting sense, and the scope of the invention is defined only by the included claims, along with the full range of equivalents to which such claims are entitled.
According to the present disclosure, a data collection apparatus, a remote control system, a data collection method, and a program that enable efficiently collecting a wide variety of types of data from a facility device system can be provided.
