(Embodiment 1)
First, the configuration of a data providing system 1000 according to the first embodiment of the present invention will be briefly described with reference to FIG. The data providing system 1000 is a system that provides measurement data, which is data obtained by measurement, and reliability information, which is information indicating the reliability of the measurement data, to a data user. The data user is, for example, a service provider that provides a service to a service user using measurement data provided from the data providing system 1000.

  The service provider provides the service to the service user by using, for example, the application server 70 that provides an application using the measurement data. Since the data user is a service provider, it is sometimes called a servicer. In this embodiment, the data providing system 1000 provides the data user with the measurement data and the reliability of the measurement data by transmitting the measurement data and the reliability information to the application server 70. As shown in FIG. 1, the data providing system 1000 includes a terminal device 20, a terminal device 30, a connection device 40, a maker server 50, and a platform server 60. Note that the numbers of the terminal devices 20 and 30, the connection devices 40, the maker server 50, and the platform server 60 are not limited to those shown in FIG.

  The terminal device 20 and the terminal device 30 are IOT (Internet of Things) -compatible devices located at the terminal of the data providing system 1000, and are, for example, equipment devices arranged in a data provider's house. The terminal device 20 and the terminal device 30 generate measurement data indicating the physical quantity by measuring a predetermined physical quantity. That is, the terminal device 20 and the terminal device 30 are equipment having a function of measuring some physical quantity. In the present embodiment, the terminal device 20 and the terminal device 30 are air conditioners, and the measurement data is room temperature.

  The connection device 40 is a device for connecting the terminal device 20 and the terminal device 30 to the maker server 50, and is, for example, a communication device arranged in the house of the data provider. The connection device 40 has, for example, a function of converting a communication protocol, and a function of uploading measurement data generated by the terminal device 20 and measurement data generated by the terminal device 30 to the maker server 50. The connection device 40 is, for example, a gateway device that controls and monitors the terminal device 20 and the terminal device 30.

  The maker server 50 is a server included in the maker cloud owned by the maker of the terminal device 20 and the terminal device 30 or the facility operator. The maker server 50 has a function of collecting and accumulating the measurement data generated by the terminal device 20 and the measurement data generated by the terminal device 30. The maker server 50 may provide the measurement data to the application server 70 via the platform server 60, or may provide the measurement data to the application server 70 without passing through the platform server 60. When providing measurement data to the application server 70 without passing through the platform server 60, the maker server 50 has a function similar to the function of the platform server 60. That is, in this case, the maker server 50 executes processing such as shaping, sorting, and anonymization on the measurement data, for example.

  The platform server 60 is a server that provides measurement data to data users. The platform server 60 is a server owned by the platform. The platformer is, for example, an IT (Information Technology) provider that processes measurement data based on personal information into anonymized big data and provides it to data users. The platform server 60 executes processes such as shaping, sorting, and anonymization on the measurement data collected from the maker server 50.

  The application server 70 is a server owned by the data user. A data user is a service provider that purchases big data from a data provider and provides a unique service to the service user. The application server 70 is a server that provides an application based on measurement data provided from the maker server 50 or the platform server 60, for example. The application server 70 corresponds to a data use device 500 described later.

  Here, the application server 70 is provided with reliability information in addition to the measurement data. This reliability information is added to the measurement data by at least a device used in a process in which the generated measurement data is provided to the application server 70. That is, the reliability information is added to the measurement data by at least one of the terminal device 20, the terminal device 30, the connection device 40, the maker server 50, and the platform server 60.

  For example, the reliability information is provided in the terminal device 20 or the terminal device 30 automatically or according to an instruction from a maintenance contractor or a contractor. For example, the terminal device 20 or the terminal device 30 automatically generates reliability information based on operation information or information of a built-in sensor. Alternatively, a maintenance contractor or a contractor may generate reliability information based on the construction information or the maintenance information and supply the generated reliability information to the terminal device 20 or the terminal device 30.

  Alternatively, the reliability information is provided in the connection device 40 automatically or in accordance with an instruction from the installer of the connection device 40. For example, the connection device 40 automatically generates reliability information based on device information acquired from the terminal device 20 or the terminal device 30, or operation information or sensor information acquired from another device. Alternatively, the installer may generate reliability information based on the installation information and supply the reliability information to the connection device 40.

  Alternatively, the reliability information is provided in the maker server 50 automatically or in accordance with an instruction from a third party organization. The third party is, for example, a specialized organization that audits reliability information. For example, the maker server 50 automatically generates the reliability information based on the device information of the connection device 40, the registration information of the data provider, the maintenance information or the inspection information by the service of the company, and the like. Alternatively, a third party may generate reliability information based on the audit information of the maker server 50 and supply the reliability information to the maker server 50.

  Alternatively, the reliability information is provided in the platform server 60 automatically or in accordance with an instruction from a third party organization. For example, the platform server 60 automatically generates reliability information based on maker information of a plurality of manufacturers collected from the plurality of maker servers 50. Alternatively, a third party may generate reliability information based on the audit information of the platform server 60 and supply the reliability information to the platform server 60.

  Next, with reference to FIG. 4, provided information that is information provided to a data user will be described. The provided information is information including measurement data and reliability information associated with the measurement data. The provided information is information stored in the data storage unit 45 and also information transmitted by the data transmission unit 44.

  The measurement data may be any data as long as it is data obtained by measurement. That is, various types can be adopted as the type of the measurement data. For example, the types of measurement data include room temperature, outside air temperature, humidity, number of people in the room, operation time, power consumption, and the like. FIG. 4 shows an example in which the type of the measurement data is room temperature. As shown in FIG. 4, the measurement data includes, for example, a data identifier and a measurement value. The data identifier is an identifier uniquely assigned to one measurement value. The measurement value is a measured value. It should be noted that the measurement data may include information such as the region where the measurement data is generated and the date and time when the measurement data is generated, as long as the data is anonymized.

  The reliability information is information indicating the reliability of the measurement data, and is information that is a factor that affects the information value of the measurement data itself. The reliability information may be any information as long as the information indicates the reliability of the measurement data. That is, various types can be adopted as the type of the reliability information. For example, types of reliability information include accuracy, stability, device control state, operation time, measurement environment, failure history, abnormality history, presence / absence of maintenance, last maintenance date, and the like.

  The accuracy is, for example, the accuracy of measurement of the sensor 105 of the measuring device 100 that generates measurement data. The accuracy is specified, for example, from the device information held by the measuring device 100. The higher the accuracy, the higher the reliability of the measurement data can be considered. The stability is an index indicating how the measurement data is blurred. The higher the stability, the higher the reliability of the measurement data can be considered. The stability includes, for example, a first stability and a second stability.

  The first stability is a stability based on the maximum variation amount of the measurement data within a unit time on the assumption that the measurement conditions are not changed. The measurement condition is, for example, a set temperature. The unit time is, for example, 24 hours = 1 day. The first stability is represented by, for example, stability / day. The first stability is classified into, for example, rank A, rank B, rank C, rank D, and rank E in descending order of stability. Rank A is set, for example, when the measurement data fluctuates less than 1 ° C. during one day. Rank B is set, for example, when the measurement data fluctuates less than 5 ° C. during one day. Rank C is set, for example, when the measurement data fluctuates less than 10 ° C. during one day. Rank D is set, for example, when the measurement data fluctuates by 10 ° C. or more during one day. The rank E is set, for example, when the measurement data cannot be measured during one day for eight consecutive hours or more. In addition, when it is applied to a plurality of ranks, the highest rank is applied. It can be considered that the higher the first stability, the higher the reliability of the measurement data.

  The second stability is extracted when the measurement data is extracted at predetermined intervals while shifting the extraction position from the measurement data generated at a predetermined period on the assumption that the measurement conditions are not changed. This is the stability based on the ratio of extraction positions where the difference between the measured data to be measured falls within a predetermined range. The predetermined cycle is, for example, 1 minute, 10 minutes, 30 minutes, 60 minutes, and the like. The predetermined interval is, for example, 24 hours × N (where N is a natural number) = Y hours. The second stability is an index indicating the magnitude of the fluctuation amount of the measurement data at the same time arriving every Y hours, that is, every N days. The second stability is represented by, for example, Y (h) stability. The second stability is classified into, for example, rank A, rank B, rank C, rank D, and rank E in descending order of stability.

  Rank A is set, for example, when the time during which the difference between a plurality of measurement data acquired in the Y time cycle is 1 ° C. or more is less than 10% in total. Rank B is set, for example, when the time during which the difference between a plurality of measurement data acquired in the Y time cycle is 1 ° C. or more is less than 30% in total. The rank C is, for example, when the difference between a plurality of measurement data obtained in the Y time cycle is less than 50% in total when the temperature is 1 ° C. or more, or the difference between the plurality of measurement data obtained in the Y time cycle. Is set when the time during which the temperature is 3 ° C. or more is less than 30% in total. The rank D is set, for example, when the time during which the difference between the plurality of measurement data acquired in the Y time cycle is 3 ° C. or more is less than 50% in total. The rank E is set, for example, when the time during which the difference between the plurality of measurement data acquired in the Y time cycle is 3 ° C. or more is 50% or more in total. In addition, when it is applied to a plurality of ranks, the highest rank is applied. It can be considered that the higher the second stability, the higher the reliability of the measurement data.

  The device control state is, for example, a control state of the measurement device 100 when the measurement device 100 has a control function in addition to the measurement function. For example, when the measuring device 100 is an air conditioner, the device control state is an operation state of the air conditioner (during cooling, heating, dehumidifying, blowing, and stopping operation). The more stable the device control state, the higher the reliability of the measurement data can be considered. The operation time is, for example, the elapsed time from when the measurement device 100 starts operating when the measurement device 100 has a control function in addition to the measurement function. For example, when the operation time is short, it is a transition period of control, and it can be considered that the reliability of the measurement data is low.

  The measurement environment is, for example, an environment of the sensor 105 included in the measurement device 100 and configured to generate measurement data. The measurement environment is, for example, a measurement place where the sensor 105 is arranged, a weather at the time of measurement by the sensor 105, and the like. For example, the reliability of the measurement data can be considered to be lower as the temperature change at the measurement location is larger and the weather is rougher. The failure history is a history in which the measuring device 100 or the sensor 105 has failed. The abnormality history is a history in which the measuring device 100 or the sensor 105 has become abnormal. For example, if there is a history of failure or abnormality, it can be considered that the reliability of the measurement data is low. The presence or absence of the maintenance is the presence or absence of the maintenance of the measuring device 100 or the sensor 105. The last maintenance date is a date on which the measurement device 100 or the sensor 105 was last maintained. For example, when maintenance is not performed for a long period of time, the reliability of the measurement data can be regarded as low.

  The method for acquiring the reliability information can be adjusted as appropriate. For example, the first stability and the second stability can be acquired from the history of the measurement data generated by the measuring device 100 (hereinafter, referred to as “generation history” as appropriate). Further, for example, the accuracy, the device control state, the operation time, and the like can be specified from the device information provided in the measuring device 100. Further, for example, the failure history, the abnormality history, the presence / absence of maintenance, the last maintenance date, and the like can be specified from the maintenance information included in the relay device 300. The source of the reliability information may be a device such as the measuring device 100, the relay device 200, the relay device 300, the data providing device 400, or a person such as a contractor, a maintenance contractor, or a third party. There may be. If the source of the reliability information is a person, the reliability information is obtained via various devices.

  Here, it is preferable that the reliability information to be given to the measurement data differs for each measurement data. That is, it is preferable that the type of the reliability information to be given to the measurement data is a type corresponding to the type of the measurement data. Therefore, in the present embodiment, the device that gives the reliability information (hereinafter, appropriately referred to as “information giving device”) specifies the reliability information to be given to the measurement data with reference to the type information. Hereinafter, the type information will be described with reference to FIG.

  As shown in FIG. 5, the type information is information for associating the type of the measurement data with the type of the reliability information. As shown in FIG. 5, at least one type of reliability information is associated with the type of measurement data. For example, in the type information, the accuracy, the first stability, the number of occupants, the device control state, and the measurement location are associated with the type of the reliability information with respect to the type of the measurement data of room temperature. In other words, this type information means that the reliability of the room temperature is related to the accuracy, the first stability, the number of occupants, the device control state, and the measurement location.

  The information providing device only needs to hold the type information on the measurement data handled by the information providing device. That is, the type information to be held may be different for each information providing apparatus. For example, in FIG. 1, the terminal device 20 only needs to hold the type information on the measurement data generated by the terminal device 20. On the other hand, the terminal device 30 only needs to hold the type information on the measurement data generated by the terminal device 30. Further, the connected device 40 only needs to hold the type information on the measurement data generated by the terminal device 20 and the measurement data generated by the terminal device 30. The information adding device may add obtainable reliability information to the measurement data among the reliability information specified by the type information. However, it is preferable that the information adding apparatus adds as much reliability information as possible that can be obtained by itself to the measurement data.

  Next, a method of providing measurement data and reliability information will be described with reference to FIG. This providing method is basically a method in which the data providing device 400 provides the data using device 500 with the measurement data and the reliability information. There are three types of providing methods, for example, a providing method using a data schema, a providing method using attached documents, and a providing method using on-demand.

  In the providing method using the data schema, the measurement data is described in a body of a data file defined by a schema such as JSON (JavaScript (registered trademark) Object Notation) or XML (Extensible Markup Language) of big data. On the other hand, the reliability information is described in the header of this data file. Since the header and the body have a one-to-one correspondence, in the providing method using the data schema, the measurement data and the reliability information have a one-to-one correspondence.

  In the method provided by the attached document, the measurement data is described in a data file. On the other hand, the reliability information is described in a file different from the data file. This other file may be a certificate format file. The data file in which the measurement data is described and the other file in which the reliability information is described need not be one-to-one. For example, a plurality of data files each describing measurement data and another file describing a plurality of pieces of reliability information given to the plurality of measurement data may be prepared.

  In the on-demand providing method, the measurement data is described in a data file. On the other hand, the reliability information may be provided on demand as needed. In this case, for example, an inquiry address or a key for download is provided to the data user in advance. Then, the data user requests the data provider to provide the reliability information when necessary, using the inquiry address or the key only for the necessary part.

  Next, an effect obtained by the data providing system 1000 according to the present embodiment will be described with reference to FIG. In FIG. 7, the data use device 500 collects the outside temperature as measurement data from the house A and the house B existing in the village X, and determines whether to transmit the disaster prevention radio to the village X based on the collected outside temperature. An example is shown below. It is assumed that the measuring device 100A is installed in the house A, and the measuring device 100B is installed in the house B. The actual outside air temperature of the village X is 35 ° C., the measurement data generated by the measurement device 100A indicates 33 ° C., and the measurement data generated by the measurement device 100B indicates 38 ° C.

  The upper part of FIG. 7 shows an example in which an erroneous solution is developed when reliability information is not used. In this example, since the data use device 500 has acquired 33 ° C. and 38 ° C. as the outside temperature of the village X, it determines that 50% of the houses whose outside temperature is 38 ° C. exist in the village X, Should send a disaster prevention radio. "

  The lower part of FIG. 7 shows an example in which a correct solution is developed when reliability information is used. Also in this example, the data use device 500 acquires 33 ° C. and 38 ° C. as the outside temperature of the village X. However, in this example, reliability information indicating that the accuracy is 1 ° C. is added to the outside temperature of 33 ° C., and reliability indicating that the accuracy is 10 ° C. is added to the outside temperature of 38 ° C. Sex information is provided. For this reason, the data use device 500 determines that the outside air temperature of 38 ° C. is the measurement data measured with low accuracy, and correctly determines “warning is unnecessary”.

  As described above, in the present embodiment, the reliability of the measurement data is provided to the data user while the anonymity of the measurement data is maintained. Therefore, the data user can, for example, exclude measurement data with low reliability or weight the measurement data according to the reliability. Alternatively, the data user can, for example, extract and analyze low-reliability measurement data to pursue problems and solutions.

  In the provision method using the data schema, basically, reliability information is added to all measurement data. Therefore, this providing method is suitable for detailed analysis processing. In the providing method using the attached document, basically, the reliability information given to the plurality of measurement data is provided by, for example, one certificate. For this reason, in this providing method, the data user can acquire only the certificate in the range used for the analysis, or can analyze only the measurement data to which the certificate has been assigned. Even in the on-demand providing method, reliability information can be acquired as needed. That is, the providing method using the attached document and the providing method using on-demand are suitable for simple or comprehensive analysis.

  Data users who especially require such reliability information, for example, hope to accurately grasp the trends of local residents, such as financial institutions and insurance companies, in addition to medical institutions and local governments taking disaster prevention measures. There are private companies or infrastructure companies.

  Next, a data providing process executed by the data providing system 1000 will be described with reference to a flowchart shown in FIG. This data providing process is a process for realizing the data providing method.

  First, the measuring device 100 determines whether or not there is acquired measurement data (step S101). For example, the measuring device 100 determines whether or not the measurement data is generated by the sensor 105. When determining that there is no acquired measurement data (step S101: NO), measuring device 100 returns the process to step S101. When measuring device 100 determines that there is acquired measurement data (step S101: YES), measuring device 100 appropriately adds reliability information to the measurement data (step S102).

  When the process of step S102 is completed, the first relay device appropriately adds reliability information to the measurement data (step S103). When the processing in step S103 is completed, the second relay device appropriately adds reliability information to the measurement data (step S104). Note that the first relay device is the relay device 200, and the second relay device is the relay device 300. When the process of step S104 is completed, the reliability information is added to the measurement data by the data providing device 400 as appropriate (step S105).

  When the processing in step S105 is completed, the data providing apparatus 400 stores the measurement data and the reliability information in association with each other (step S106). When the processing in step S106 is completed, the data providing apparatus 400 determines whether there is a request for transmitting measurement data (step S107). For example, the data providing device 400 determines whether or not information indicating a request for transmitting measurement data has been received by the communication interface 403 from the data using device 500.

  If the data providing device 400 determines that there is no request for transmitting the measurement data (step S107: NO), the process returns to step S101. When determining that there is a request for transmitting the measurement data (step S107: YES), the data providing apparatus 400 transmits the measurement data and the reliability information to the data using apparatus 500 (step S108). Upon completion of the process in step S108, the data providing device 400 returns the process to step S101.

  In the present embodiment, the measurement data and the reliability information given to the measurement data are provided to the data user. This reliability information is information indicating a fair and clear index according to the type of the measurement data. Therefore, the data user can exclude low-reliability measurement data or weight measurement data according to reliability. Further, the data user can extract and analyze low-reliability measurement data, find a problem, and take measures. Thus, according to the present embodiment, effective use of the measurement data can be expected. It is not necessary to include information indicating the source of the measurement data in the reliability information for determining the reliability of the measurement data, so that the anonymity of the measurement data is maintained.
