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 this measurement data, to data users. A data user is, for example, a service provider that uses measurement data provided by the data providing system 1000 to provide services to service users.

The service provider provides services to service users using, for example, an application server 70 that provides applications using measurement data. Since data users are service providers, they are sometimes called servicers. 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 .

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 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 types of measurement data. For example, types of measurement data include room temperature, outside temperature, humidity, number of people in the room, operating time, and power consumption. FIG. 4 shows an example in which the type of measurement data is room temperature. As shown in FIG. 4, the measurement data includes, for example, data identifiers and measurement values. A data identifier is an identifier uniquely assigned to one measured value. A measured value is a measured value. Note that the measurement data may include information such as the area where it was generated and the date and time when it was generated, as long as it is anonymized data.

Reliability information is information representing the reliability of measurement data, and is information that determines the informational value of the measurement data itself. The reliability information may be any information as long as it represents the reliability of the measurement data. That is, various types can be adopted as the types of reliability information. For example, the types of reliability information include accuracy, stability, device control state, operating 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 that generates the measurement data and is included in the measuring device 100 . Accuracy is specified, for example, from device information held by the measuring device 100 . It can be considered that the higher the accuracy, the higher the reliability of the measurement data. Stability is an index that indicates how the measurement data blurs. It can be considered that the higher the stability, the higher the reliability of the measurement data. Stability includes, for example, first stability and second stability.

The first degree of stability is the degree of stability based on the maximum fluctuation amount of the measurement data within a unit time, on the premise that the measurement conditions have not changed. The measurement condition is, for example, the set temperature. A unit time is, for example, 24 hours=1 day. The first stability is expressed by, for example, stability/day. The first stability is classified into rank A, rank B, rank C, rank D, and rank E, for example, in descending order of stability. Rank A is set, for example, when the measurement data fluctuates by less than 1° C. during one day. Rank B is set, for example, when the measurement data fluctuates by less than 5°C during one day. Rank C is set, for example, when the measurement data fluctuates by 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. Rank E is set, for example, when the measurement data is not measurable for eight consecutive hours or more in one day. If multiple ranks apply, the highest rank will be 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 measuring data is extracted at predetermined intervals while shifting the extraction position from the measurement data generated at predetermined intervals on the premise that there is no change in the measurement conditions. It is the stability based on the ratio of the extraction positions where the difference in the measured data obtained is within a predetermined range. The predetermined period is, for example, 1 minute, 10 minutes, 30 minutes, 60 minutes, or 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 that indicates the amount of variation in the measurement data at the same time that arrives every Y hours, that is, every N days. The second stability is expressed by Y(h) stability, for example. The second stability is classified into rank A, rank B, rank C, rank D, and rank E, for example, in descending order of stability.

Rank A is set, for example, when a total of less than 10% of the time is 1° C. or more in the difference between a plurality of measurement data acquired in the Y time period. Rank B is set, for example, when a total of less than 30% of the time is less than 30% when the difference between a plurality of pieces of measurement data acquired in the Y time period is 1° C. or more. Rank C is, for example, when the difference between the plurality of measurement data obtained in the Y time period is 1 ° C or more in total less than 50% of the time, or when the difference in the plurality of measurement data obtained in the Y time period is 3°C or higher less than 30% of the total time. Rank D is set, for example, when a total of less than 50% of the time is less than 3° C. in the difference between a plurality of pieces of measurement data acquired in the Y time period. Rank E is set, for example, when a total of 50% or more of the time has a difference of 3° C. or more between a plurality of pieces of measurement data acquired in the Y time period. If multiple ranks apply, the highest rank will be 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, the control state of the measuring device 100 when the measuring device 100 has a control function in addition to the measuring function. For example, when the measuring device 100 is an air conditioner, the device control state is the operating state of the air conditioner (during cooling, heating, dehumidifying, blowing air, and not operating). It can be considered that the more stable the device control state, the higher the reliability of the measurement data. The operating time is, for example, the elapsed time from when the measuring device 100 starts operating when the measuring device 100 has a control function in addition to the measuring function. For example, if the operation time is short, it can be considered that the control is in a transition period and the reliability of the measurement data is low.

The measurement environment is, for example, the environment of the sensor 105 that generates measurement data and is provided in the measurement apparatus 100 . The measurement environment includes, for example, the measurement location where the sensor 105 is arranged, the weather at the time of measurement by the sensor 105, and the like. For example, it can be considered that the greater the temperature change at the measurement location or the rougher the weather, the lower the reliability of the measurement data. The failure history is a history of failures of the measuring device 100 or the sensor 105 . The abnormality history is a history of abnormalities in the measuring device 100 or the sensor 105 . For example, if there is a history of failures or abnormalities, it can be considered that the reliability of the measurement data is low. The presence/absence of maintenance is the presence/absence of maintenance of the measuring device 100 or the sensor 105 . The date of last maintenance is the date when the measuring device 100 or the sensor 105 was last maintained. For example, if it has not been maintained for a long period of time, it can be considered that the reliability of the measurement data is low.

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

Here, it is preferable that the reliability information to be added to the measurement data is different for each measurement data. That is, it is preferable that the type of reliability information to be added to the measurement data is a type corresponding to the type of the measurement data. Therefore, in the present embodiment, a device for adding reliability information (hereinafter referred to as an "information adding device" as appropriate) refers to the type information to specify reliability information to be added to the measurement data. The type information will be described below with reference to FIG.

As shown in FIG. 5, the type information is information that associates the type of measurement data with the type of reliability information. As shown in FIG. 5, at least one type of reliability information is associated with a type of measurement data. For example, in the type information, accuracy, first stability, number of people in the room, device control state, and measurement location are associated with the type of measurement data, room temperature, as types of reliability information. 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 people in the room, the device control state, and the measurement location.

The information providing device only needs to hold the type information related to the measurement data handled by the information providing device. That is, the type information to be held may be different for each information providing device. For example, in FIG. 1, the terminal device 20 may hold the type information regarding the measurement data generated by the terminal device 20 . On the other hand, the terminal device 30 only needs to hold the type information regarding the measurement data generated by the terminal device 30 . Also, the connection device 40 only needs to hold type information regarding 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 among the reliability information specified by the type information to the measurement data. However, it is preferable for the information adding device to add as much reliability information as it can acquire 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 utilization device 500 with measurement data and reliability information. There are three methods of provision, for example, a method of providing by data schema, a method of providing by attached documents, and a method of providing on demand.

In the data schema provision method, measurement data is described in the 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, reliability information is written in the header of this data file. Since there is a one-to-one correspondence between the header and the body, the measurement data and the reliability information correspond one-to-one in the data schema-based provision method.

In the attachment method, measurement data is described in a data file. On the other hand, reliability information is written in a file separate from this data file. This separate file may be in certificate format. The data file in which the measurement data is described and the separate file in which the reliability information is described may 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 assigned to the plurality of measurement data may be prepared.

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

Next, with reference to FIG. 7, effects obtained by the data providing system 1000 according to this embodiment will be described. In FIG. 7, the data utilization device 500 collects outside temperatures as measurement data from houses A and B in village X, and determines whether or not disaster prevention radio should be transmitted to village X based on the collected outside temperatures. Here is an example of 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. It is also assumed that the actual outside 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 of an incorrect solution being deployed without trust information. In this example, the data utilization device 500 acquires 33° C. and 38° C. as the outside temperatures of village X, and therefore determines that 50% of the houses with an outside temperature of 38° C. exist in village X. should broadcast the disaster prevention radio."

The lower part of FIG. 7 shows an example of how the correct solution is developed when using reliability information. In this example as well, the data utilization device 500 acquires 33° C. and 38° C. as the outside temperatures of the village X. FIG. However, in this example, an outside temperature of 33°C is given a confidence value indicating an accuracy of 1°C, and an outside temperature of 38°C is given a confidence value indicating an accuracy of 10°C. given sexual information. Therefore, the data utilization device 500 determines that the outside air temperature of 38° C. is measurement data measured with low accuracy, and correctly determines that "a warning is unnecessary."

Thus, in this embodiment, the reliability of the measurement data is provided to the data user while maintaining the anonymity of the measurement data. Therefore, data users can, for example, exclude measurement data with low reliability or weight measurement data according to reliability. Alternatively, data users can, for example, extract and analyze unreliable measurement data to pursue problems and solutions.

In the data schema providing method, reliability information is basically attached to all measurement data. Therefore, this provision method is suitable for detailed analysis processing. In the method of providing information using attached documents, reliability information attached to a plurality of pieces of measurement data is basically provided by, for example, one certificate. Therefore, in this provision method, the data user can acquire only the certificate for the range used for analysis, or can analyze only the measurement data to which the certificate is attached. Even in the on-demand provision method, reliability information can be obtained as needed. In other words, the method of providing by attachment and the method of providing on demand are suitable for simple or comprehensive analysis.

Data users who particularly need such reliability information include, for example, medical institutions, local governments that take disaster prevention measures, as well as financial companies and insurance companies. There are private companies and infrastructure companies.

Next, data provision processing executed by the data provision system 1000 will be described with reference to the 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 sensor 105 has generated measurement data. When determining that there is no acquired measurement data (step S101: NO), the measuring device 100 returns the process to step S101. When the measurement device 100 determines that there is acquired measurement data (step S101: YES), the measurement device 100 appropriately adds reliability information to the measurement data (step S102).

When the process of step S102 is completed, reliability information is appropriately added to the measurement data by the first relay device (step S103). When the process of step S103 is completed, reliability information is appropriately added to the measurement data by the second relay device (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 data providing device 400 appropriately adds reliability information to the measurement data (step S105).

When the process of step S105 is completed, the data providing device 400 associates the measurement data with the reliability information and stores them (step S106). When the process of step S106 is completed, the data providing device 400 determines whether or not there is a transmission request for measurement data (step S107). For example, the data providing device 400 determines whether or not the communication interface 403 has received information indicating a measurement data transmission request from the data utilization device 500 .

When the data providing device 400 determines that there is no measurement data transmission request (step S107: NO), the process returns to step S101. When the data providing device 400 determines that there is a transmission request for measurement data (step S107: YES), it transmits the measurement data and the reliability information to the data utilization device 500 (step S108). After completing the process of step S108, the data providing device 400 returns the process to step S101.

In this embodiment, the measurement data and the reliability information attached to the measurement data are provided to the data user. This reliability information is information that indicates a fair and clear index according to the type of measurement data. Therefore, the data user can exclude measurement data with low reliability or weight the measurement data according to reliability. Data users can also extract and analyze unreliable measurement data, discover problems, and take countermeasures. Thus, according to the present embodiment, effective use of measurement data can be expected. The reliability information for determining the reliability of the measurement data does not need to include information indicating the source of the measurement data, so the anonymity of the measurement data is maintained.

When the first reliability information is attached to the first measurement data, the data receiving section 21 receives the first reliability information from the measuring device 100A. The data receiving unit 21 receives the second measurement data generated by the measuring device 100B from the measuring device 100B. When the second reliability information is added to the second measurement data, the data receiving section 21 receives the second reliability information from the measuring device 100B.
