<System configuration example>
FIG. 1 is an explanatory diagram of a system configuration example of the cooperation system according to the first embodiment. The cooperation system 100 includes a management device 101 and one or more collection devices 102. The management device 101 is a computer that manages one or more collection devices 102. The collection device 102 is a computer that collects data from a site. A field system 120 such as a factory or a power plant is arranged at the base. The collection device 102 collects data from this field system. The management device 101 and the collection device 102 are communicably connected via a network 103 such as a LAN (Local Area Network), a WAN (Wide Area Network), or the Internet.

In the first embodiment, when the management apparatus 101 wants to obtain desired data by using the data collected by the site system 120 at the site, the difference in specifications regarding data between the management apparatus 101 and the collection apparatus 102 is considered. The data is absorbed and the data desired by the management apparatus 101 is acquired. In particular, the collection device 102 generates desired data as if it were the management device 101, so that the data cooperation between the management device 101 and the collection device 102 is smoothly realized. Here, when the cooperation system 100 is installed in a certain company, the management device 101 is, for example, a computer used in the head office of the certain company, and the collection device 102 is a computer used in each base of the certain company. is there.

First, the collection device 102 will be described. The collection device 102 has a site DB 121, a data model 122, a service DB 123, and a first context CTX1. The site DB 121 stores the site data collected from the site system 120. The on-site data is data such as temperature, humidity, concentration, pressure, water level, and discharge amount observed by a sensor included in an on-site system at the site of the site.

The data model 122 is data that models the on-site system 120 serving as a base. Specifically, for example, the data model 122 includes the location and identification information of sensors provided in the field system 120. For example, “S1” and “S2” in the site DB 121 are identification information used by the collection device 102.

The service DB 123 stores service data. Service data is data converted from field data. For example, “D1” and “M1” in the service DB 123 are identification information used by the management apparatus 101.

The first context CTX1 is information (related information) related to the on-site data, and specifically, for example, descriptive information regarding the specifications of the on-site data (hereinafter, first descriptive information) and a storage location in the on-site DB 121. And position information indicating.

The first description information is, for example, identification information (for example, “S1”, “S2”,..., Hereinafter, first identification information) of the sensor that is the detection source of the site data and the detection of the site data. The name (for example, “GT-2X4Y”, “AT-1A”,...) In the on-site system 120 in which the type and attribute of the original sensor can be specified, and the unit of the on-site data output by the sensor that is the detection source (for example, , “K”, “°F”,..., Hereinafter, the first unit). The position information is, for example, a pointer indicating the position of the entry in the site DB 121 in which the site data is stored. Details of the first context CTX1 will be described later with reference to FIG.

Further, when the second context CTX2 is transmitted from the management device 101, the collection device 102 receives and holds the second context CTX2. The second context CTX2 is information (related information) related to the service data, and specifically, for example, description information (hereinafter referred to as second description information) regarding specifications of the service data, field data and service data. And the correspondence relationship.

The second explanation information is, for example, identification information (for example, “D1”, “D2”, “M1”,..., Hereinafter, second identification information) of the sensor that is the detection source of the site data in the management device 101, The name (for example, “Gas Temp”, “Air Temp”,...) In the management device 101 that can specify the type or attribute of the sensor that is the detection source of the site data, and the site data that the sensor that is the detection source outputs The corresponding service data unit (for example, “K”, “°C”,..., Hereinafter, second unit) is included.

The correspondence is, for example, a correspondence table of the first identification information and the second identification information specified as the same sensor on the data model 122. Thereby, the on-site data and the service data are associated with each other, and the collection device 102 converts the on-site data into the service data according to the conversion rule. For example, the collection device 102 performs unit conversion or granularity change of data according to the conversion rule. More specifically, for example, the collection device 102 converts the site data of the first unit into the service data of the second unit.

In addition, the collection device 102 converts the on-site data into the representative value required for the service data. For example, if the detection cycle, which is the granularity of the on-site data, is 1 second, the number of on-site data collected per minute will be 60 pieces. When the representative value required for the service data is the average value, the collecting apparatus 102 calculates the average value that is the representative value from the 60 pieces of site data, and uses the average value as the second unit of the service data, for example. Convert units.

Further, the second context CTX2 may include an arithmetic expression using service data or field data (for example, α1=av(M)). “Α1” on the left side of the arithmetic expression is target data requested by the management apparatus 101. The right side shows the average value of the service data including “M” in the second identification information. Details of the second context CTX2 will be described later with reference to FIG.

Next, the management device 101 will be described. The management apparatus 101 has a business application and a second context CTX2. The business application is an application program for transmitting a request for the target data α1 to the collection device 102, receiving and displaying the target data α1, and transmitting the second context CTX2 to the collection device 102. In addition, the management apparatus 101 newly creates or updates the second context CTX2 by the operation of the administrator.

Note that, in FIG. 1, the request and acquisition of the target data are executed with respect to a certain collecting apparatus 102, but the request and the acquisition of the target data can be simultaneously and repeatedly executed with respect to other collecting apparatuses 102 as well. .. Therefore, even when the request and acquisition of the target data are concentrated on each of the plurality of collecting devices 102, the management device 101 collects the service data for calculating each target data and calculates the target data itself. No need to do. Therefore, the load is not concentrated on the management apparatus 101, and the load is distributed.

<Computer hardware configuration example>
FIG. 2 is a block diagram showing an example of the hardware configuration of the computer (the management device 101 and the collection device 102). The computer 200 includes a processor 201, a storage device 202, an input device 203, an output device 204, and a communication interface (communication IF) 205. The processor 201, the storage device 202, the input device 203, the output device 204, and the communication IF 205 are connected by the bus 206. The processor 201 controls the computer 200.

The storage device 202 serves as a work area of the processor 201. The storage device 202 is a non-temporary or temporary recording medium that stores various programs and data. Examples of the storage device 202 include a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), and a flash memory. The input device 203 inputs data. Examples of the input device 203 include a keyboard, a mouse, a touch panel, a numeric keypad, and a scanner. The output device 204 outputs data. Examples of the output device 204 include a display and a printer. The communication IF 205 connects to a network and transmits/receives data.

<Various data>
FIG. 3 is an explanatory diagram showing an example of stored contents of the site DB 121 shown in FIG. The site DB 121 has a time 301 and a sensor ID 302. The value at time 301 indicates the observation time at the sensor. The value of the sensor ID 302 indicates the first identification information. In FIG. 3, for example, “s11” is the on-site data observed at the value t1 at time 301 by the sensor having the sensor ID 302 value of “S1” (hereinafter, sensor S1).

FIG. 4 is an explanatory diagram showing an example of stored contents of the first context CTX1. The first context CTX1 has a sensor ID 401, a sensor type 402, a unit 403, a detection cycle 404, a collection frequency 405, and a storage destination 406. The value of the sensor ID 401 indicates the first identification information. The value of the sensor type 402 indicates the type of sensor specified by the sensor ID 401. The value of the unit 403 indicates the unit of field data, that is, the first unit. The value of the detection cycle 404 indicates the cycle of detecting the on-site data by the sensor specified by the sensor ID 401. The value of the collection frequency 405 indicates the frequency with which the collection device 102 collects the site data from the site system 120. The value of the storage destination 406 indicates the above-mentioned position information (for example, pointer).

FIG. 5 is an explanatory diagram showing an example of stored contents of the second context CTX2. The second context CTX2 has a sensor ID 501, a corresponding sensor ID 502, a unit 503, a representative value 504, and an arithmetic expression F. The value of the sensor ID 501 indicates the second identification information. The value of the corresponding sensor ID 502 indicates the first identification information. That is, the sensor ID 501 and the corresponding sensor ID 502 are the above-mentioned corresponding information. Therefore, in the data model 122, for example, for the same sensor, the sensor that was specified as “S1” in the field is specified as “M201” in the management apparatus 101.

The value of the unit 503 indicates the unit of service data, that is, the second unit. The unit 503 is one of the conversion rules when converting site data to service data. The representative value 504 is a value representing a plurality of site data collected in the detection cycle 404. The conversion into the representative value 504 is also one of the conversion rules when converting the site data into the service data.

Examples of the representative value 504 include “average value”, “maximum value”, “minimum value”, “median value”, and “none”. For example, when the representative value 504 is the “average value”, if there are 10 spot data observed by the sensor S1 in a certain time zone, the average value of the 10 spot data is calculated as the representative value 504, and the spot value 504 is calculated. The average value of the data is converted in the unit 503 and becomes one service data.

Further, when the representative value 504 is “none”, if there are 10 spot data observed by the sensor S1 in a certain time zone, each of the 10 spot data is converted into a unit 503, and 10 spot data are obtained. It becomes service data.

The calculation formula F is a formula that outputs target data (for example, an average value) as a calculation result when service data (for example, T201 to T300) (may be on-site data) is substituted into the corresponding variable. The sensor ID 501, the unit 503, the representative value 504, and the arithmetic expression F become the second explanation information.

<Example of functional configuration of cooperation system 100>
FIG. 6 is a block diagram showing a functional configuration example of the cooperation system 100. The collection device 102 includes an acquisition unit 601, an update unit 602, a conversion unit 603, a first calculation unit 605, and a transmission unit 604. The management device has a second calculation unit 606. These are specifically realized by causing the processor 201 to execute the program stored in the storage device 202 shown in FIG. 2, for example.

When the acquisition request for the second data from the management target is received, the acquisition unit 601 corresponds to the second data based on the correspondence relationship included in the second context CTX2 and the position information included in the first context CTX1. Obtain the first data from the database. Specifically, for example, when the acquisition request for service data from the field system 120, which is an example of the second data, is received from the management apparatus 101, the acquisition unit 601 includes the sensor ID 501 included in the second context CTX2 and the corresponding information. Based on the sensor ID 502 and the storage destination 406 included in the first context CTX1, the site data corresponding to the plurality of service data is acquired from the site DB 121. The site data is an example of first data.

Further, the acquisition unit 601 may acquire the acquired second context CTX2 in the collection device 102. Further, the acquisition unit 601 may acquire the second context CTX2 from the management device 101 together with the service data acquisition request. Further, when the acquisition unit 601 receives a service data acquisition request from the management apparatus 101, the acquisition unit 601 confirms whether the second context CTX2 has been acquired from the management apparatus 101. If it has not been acquired, the acquisition unit 601 acquires the second context CTX2 from the management apparatus 101.

When the second context CTX2 is stored in the collection device 102, the update unit 602 updates the latest second context CTX2 transmitted from the management device 101.

The conversion unit 603 converts the first data acquired by the acquisition unit 601 into second data based on the correspondence relationship and the second description information included in the second context CTX2. Specifically, for example, the conversion unit 603 is acquired by the acquisition unit 601 based on the sensor ID 501 and the corresponding sensor ID 502 included in the second context CTX2, the sensor ID 501, the unit 503, and the representative value 504. Convert site data to service data.

The transmission unit 604 transmits the second data converted by the conversion unit 603 to the management device 101. Specifically, for example, the transmission unit 604 transmits the service data, which is the data converted by the conversion unit 603, to the management apparatus 101.

When the first calculation unit 605 receives a request for acquiring the first calculation result when the second data is given to the first calculation formula from the management apparatus 101, the first calculation unit 605 converts the second data converted by the conversion unit 603 into the first data. By giving it to the arithmetic expression, the third data is calculated as the first arithmetic result. Specifically, for example, when the first calculation unit 605 receives from the management apparatus 101 a request to acquire the calculation result when the service data is given to the calculation formula F, the first calculation unit 605 calculates the service data after conversion by the conversion unit 603. By giving it to the calculation formula F, the target data is calculated as the calculation result. In this case, the transmission unit 604 transmits the target data calculated by the first calculation unit 605 to the management device 101. The second calculator 606 is a function used in the second embodiment and will be described later in the second embodiment.

<Example of sequence in cooperation system 100>
FIG. 7 is a sequence diagram illustrating a sequence example in the cooperation system 100 according to the first embodiment. The management device 101 transmits a target data acquisition request to the collection device 102 (step S701). Upon receiving the acquisition request, the collection device 102 executes the second context search process (step S702) and the target data calculation process (step S703). In the second context search process (step S702), the acquisition device 601 of the collection device 102 searches the collection device 102 for the second context CTX2. Details of the second context search process (step S702) will be described later with reference to FIG.

In the target data calculation process (step S703), the first calculation unit 605 calculates the target data. Details of the target data calculation process (step S703) will be described later with reference to FIG. When the target data is calculated by the target data calculation process (step S703), the collection device 102 transmits the calculated target data to the management device 101.

The management apparatus 101 receives the calculation result from the collection apparatus 102 (step S705). The management device 101 displays the target data on the display. As a result, the user of the management apparatus 101 can confirm the target data that is the calculation result, or can provide the data to any application.

When it is desired to update the second context CTX2, the management device 101 transmits the latest second context CTX2 to the collection device 102 (step S706). When the collection device 102 receives the latest second context CTX2 from the management device 101 (step S707), the updating unit 602 updates the second context CTX2 to the latest second context CTX2 (step S708). It should be noted that the processing after S706 may be arbitrarily performed before the processing of S701 is performed.

FIG. 8 is a flowchart showing a detailed processing procedure example of the second context search processing (step S702) shown in FIG. The collection device 102 searches for the second context CTX2 in the collection device 102 (step S801). When the second context CTX2 exists (step S802: Yes), the process moves to the target data calculation process (step S703) and the second context search process (step S702) ends. When the second context CTX2 does not exist (step S802: No), the collection device 102 transmits an acquisition request for the second context CTX2 to the management device 101 (step S803).

The management apparatus 101 waits for the acquisition request of the second context CTX2 from the collection apparatus 102 (step S811: No), and when the acquisition request is received (step S811: Yes), the second context CTX2 is sent to the collection apparatus 102. It is transmitted (step S812).

When the collection device 102 waits for the reception of the second context CTX2 from the management device 101 (step S: No 804) and receives the second context CTX2 from the management device 101 within a predetermined time after transmitting the acquisition request (step S803). (Step S804: Yes), and returns to step S802. On the other hand, when the second context CTX2 is not received from the management apparatus 101 within the predetermined time (step S804: No), the second context CTX2 does not exist in the collection apparatus 102, and NG is transmitted as the calculation result ( Step S704).

FIG. 9 is a flowchart showing a detailed processing procedure example of the target data calculation processing (step S703) shown in FIG. The collection device 102 retrieves the first context CTX1 from the second context CTX2 (step S901). Specifically, for example, the collection device 102 searches for the first context CTX1 including the same sensor ID 401 as the corresponding sensor ID 502 of the second context CTX2 (step S901).

When the first context CTX1 does not exist (step S902: No), the collection device 102 ends the target data calculation process (step S703) and transmits NG as the calculation result (step S704).

On the other hand, when the first context CTX1 exists (step S902: Yes), the collection device 102 stores the site data from the sensor of the sensor ID of the first context CTX1 that is the same as the corresponding sensor ID 502 of the second context CTX2. Is specified (step S903).

Next, in the collection device 102, the acquisition unit 601 acquires the site data from the specified storage destination in the site DB 121 (step S904). Then, in the collection device 102, the conversion unit 603 converts the site data into service data (step S905), and the first calculation unit 605 calculates target data from the converted service data (step S906). Thereby, the collection device 102 ends the target data calculation process (step S703), and transmits the target data calculated in step S906 as the calculation result (step S704). As a result, the management apparatus 101 does not need to calculate the target data and can avoid load concentration.

Example 2 will be described. In the first embodiment, by providing a certain collection device 102 with the second context CTX2 of the management device 101, the collection device 102 is caused to perform conversion into service data and calculation of target data, thereby distributing the load on the management device 101. It was On the other hand, in the second embodiment, the second context CTX2 of the management device 101 is given to each of the plurality of collection devices 102 to cause each collection device 102 to execute conversion into service data and calculation of intermediate data. The management apparatus 101 calculates target data from a plurality of intermediate data. As a result, the collection apparatus 102 is caused to perform conversion into service data and calculation of intermediate data, and the management apparatus 101 executes processing that can only be performed by the management apparatus 101, thereby distributing the load on the management apparatus 101.

Further, the collection device 102a (hereinafter, the first collection device 102a) is the collection device 102 that has received the second context CTX2 from the management device 101 described in the first embodiment. Therefore, “a” is added to the end of the reference numerals of the configurations related to the collecting apparatus 102, and the description of those configurations may be applied or omitted from the first embodiment.

The calculation formula FC is a formula for calculating a weighted average of the intermediate data from the first collecting device 102a and the intermediate data from the second collecting device 102b as the target data. The weight depends on the number of pieces of site data from which each intermediate data is calculated. For example, it is assumed that the intermediate data from the first collecting apparatus 102a is calculated from 100 pieces of field data, and the intermediate data from the second collecting apparatus 102b is calculated from 60 pieces of field data. In this case, the weight given to the intermediate data from the first collecting apparatus 102a is 100/(100+60), and the weight given to the intermediate data from the second collecting apparatus 102b is 60/(100+60). ..

In addition, in FIG. 10, the request and acquisition of the intermediate data are executed with respect to the two collection devices 102 (the first collection device 102a and the second collection device 102b), but the three or more collection devices 102 are also executed. Similarly, it is possible to request and acquire intermediate data. Therefore, even when the requests and acquisitions of the intermediate data are concentrated on each of the plurality of collecting devices 102, the management device 101 collects the service data for calculating each intermediate data and calculates the target data itself. No need to do. Therefore, the management apparatus 101 can calculate the target data β without concentrating the load on the management apparatus 101, and the load distribution is realized.

FIG. 11 is an explanatory diagram showing an example of stored contents of the site DB 121b shown in FIG. In FIG. 11, for example, “r11” is the on-site data observed at time t1 by the sensor whose sensor ID is “R1”.

FIG. 12 is an explanatory diagram of an example of stored contents of the first context CTX 1b according to the second embodiment. When the field systems 120a and 120b have the same configuration, the content of the first context CTX1b may be the same as that of the first context CTX1a.

FIG. 13 is an explanatory diagram of an example of stored contents of the second context CTX 2b according to the second embodiment. The second context CTX2b has a sensor ID 501, a corresponding sensor ID 502, a unit 503, a representative value 504, and an arithmetic expression Fb. In the data model 122b, for example, for the same sensor, the sensor called “R1” in the field is called “W201” in the management apparatus 101. When the service data (for example, V301 to V360) is given, the arithmetic expression Fb outputs intermediate data (for example, an average value) as a calculation result.

Further, in FIG. 6, the management device 101 has a second calculation unit 606. The second calculation unit 606 calculates the target data β by the third context CTX3 using the intermediate data transmitted from each collection device 102. When the field systems 120a and 120b have the same configuration, the content of the second context CTX2b may be the same as that of the second context CTX2a.

<Example of sequence in cooperation system 100>
FIG. 14 is a sequence diagram illustrating a sequence example in the cooperation system 100 according to the second embodiment. The same steps as those in FIG. 7 are designated by the same step numbers and the description thereof is omitted. The management apparatus 101 transmits an acquisition request for intermediate data, which is a source of calculation of target data, to the first collection apparatus 102a and the second collection apparatus 102b (step S1401). Upon receiving the acquisition request, the first collection device 102a and the second collection device 102b execute the second context search process (step S702) and the intermediate data calculation process (step S1403).

In the intermediate data calculation process (step S1403), the first calculation unit 605 calculates the intermediate data. Details of the intermediate data calculation process (step S1403) will be described later with reference to FIG. When the intermediate data is calculated by the intermediate data calculation process (step S1403), the first collection device 102a and the second collection device 102b transmit the calculation result intermediate data to the management device 101.

The management apparatus 101 receives the calculation results from the first collecting apparatus 102a and the second collecting apparatus 102b (step S705). The management apparatus 101 uses the received intermediate data to calculate the target data β using the arithmetic expression Fc included in the third context CTX3 (step S1405). The management device 101 displays the target data on the display, whereby the user of the management device 101 can confirm the target data as the calculation result or can provide the data to any application.

When updating the second context CTX2, the management apparatus 101 transmits the latest second context CTX2 to the first collecting apparatus 102a and the second collecting apparatus 102b (step S706). When the first collection device 102a and the second collection device 102b receive the latest second context CTX2 from the management device 101 (step S707), the updating unit 602 updates the second context CTX2 to the latest second context CTX2. (Step S708). The processing after S706 may be performed at an arbitrary time such as before the processing of S1401.

FIG. 15 is a flowchart showing a detailed processing procedure example of the intermediate data calculation processing (step S1403) shown in FIG. The first collection device 102a and the second collection device 102b retrieve the first context CTX1 from the second context CTX2 (step S901). Specifically, for example, the collection device 102 searches for the first context CTX1 including the same sensor ID 401 as the corresponding sensor ID 502 of the second context CTX2 (step S901).

When the first context CTX1 does not exist (step S902: No), the first collection device 102a and the second collection device 102b end the intermediate data calculation process (step S1403) and transmit NG as the calculation result (step S704). ).

On the other hand, when the first context CTX1 exists (step S902: Yes), the first collection device 102a and the second collection device 102b have the same sensor ID 502 of the first context CTX1 as the corresponding sensor ID 502 of the second context CTX2. The storage location of the on-site data from the sensor is specified (step S903).

Next, the first collection device 102a and the second collection device 102b use the acquisition unit 601 to acquire the site data from the specified storage destinations in the site DBs 121a and 121b (step S904). Then, in the first collection device 102a and the second collection device 102b, the conversion unit 603 converts the site data into service data (step S905), and the first calculation unit 605 calculates intermediate data with the converted service data. (Step S1506). As a result, the first collection device 102a and the second collection device 102b end the intermediate data calculation process (step S1403), and transmit the intermediate data calculated in step S1506 as the calculation result (step S704). As a result, the management apparatus 101 does not need to calculate the intermediate data and can avoid load concentration.
