Plants are equipped with a variety of equipment, including motors. Large-scale plants can have more than 1,000 motors. Furthermore, when designing a plant, designers must review the equipment data sheets submitted by vendors for each of the motors and other equipment to be installed in the plant, to confirm that the vendor's equipment meets the requirements for the plant being designed. This process can be extremely cumbersome for designers.

The present invention solves these problems by providing an equipment data determination system that can reduce the time required to review equipment data sheets.

The equipment data determination system of the present invention includes: a data sheet acquisition device having a trained model that, in response to input of an equipment data sheet listing ratings for multiple items related to equipment installed in a plant, associates letters or numbers indicating the ratings for each item from the equipment data sheet with the corresponding item and outputs them as rating information; a memory unit that stores condition information indicating, for each of the multiple items, the conditions required by the plant in which the equipment is installed; and an equipment data determination device having a calculation unit that generates judgment information indicating whether the ratings listed in the equipment data sheet satisfy the conditions for each item. The calculation unit acquires the rating information output from the trained model and the condition information stored in the memory unit, generates judgment information indicating whether the ratings indicated by the rating information for each item satisfy the conditions indicated by the condition information, and executes processing to output the judgment information.

The equipment data determination system of the present invention can reduce the time required to review equipment data sheets.

(Configuration and Function of Device Data Determination System According to the Embodiment)
FIG. 1 is a configuration diagram of a device data determination system according to an embodiment.

The equipment data determination system 1 includes a data sheet acquisition device 2 and multiple equipment data determination devices 3, and determines whether the ratings listed in the equipment data sheets of equipment such as motors installed in a plant meet the conditions required by the plant. The data sheet acquisition device 2 is communicatively connected to each of the multiple equipment data determination devices 3 via a network 4 such as the Internet or an intranet. In this specification, an embodiment is described using a motor as an example of equipment, but this is merely an example, and the present invention can be applied to other equipment as well.

(Configuration and Functions of the Data Sheet Acquisition Device According to the First Embodiment)
FIG. 2 is a block diagram of the data sheet acquisition device according to the first embodiment.

The data sheet acquisition device 2 has a server communication unit 11, a server storage unit 12, a server input unit 13, a server display unit 14, and a server calculation unit 15, and is configured, for example, as a server-type computer or a cloud-based computer. The server communication unit 11 is configured to enable the data sheet acquisition device 2 to communicate with each of the multiple device data determination devices 3, and is equipped with a communication interface circuit. The communication interface circuit is, for example, a communication interface circuit for a wired LAN, a wireless LAN, LTE, or the like. The server communication unit 11 supplies data received from the multiple device data determination devices 3 to the server calculation unit 15, and transmits data supplied from the server calculation unit 15 to each of the multiple device data determination devices 3.

The server storage unit 12 is configured to store data and programs and includes, for example, semiconductor memory. The server storage unit 12 stores operating system programs, driver programs, application programs, data, etc. used in processing by the server calculation unit 15. The server storage unit 12 stores, for example, a rating information acquisition program that causes the server calculation unit 15 to execute a rating information acquisition process that acquires letters or numbers indicating the ratings of multiple items related to equipment listed on an equipment data sheet. The rating information acquisition program is installed into the server storage unit 12, for example, from a computer-readable, non-transitory, portable storage medium such as a CD-ROM or DVD-ROM, or from another server communicatively connected via the network 4. The server storage unit 12 also stores various data and information used when executing the rating information acquisition process. For example, the server storage unit 12 stores the trained model 120.

The trained model 120 is a learning model that is pre-trained through supervised learning, including machine learning by deep learning using neural networks and machine learning using support vector machines. In response to input of an equipment data sheet listing the ratings of multiple items related to equipment installed in a plant, the trained model 120 associates letters or numbers indicating the rating for each item from the equipment data sheet with the corresponding item and outputs them as rating information 121. The trained model 120 may also store data indicating the readout reliability of the read letters or numbers along with the read letters or numbers.

The trained model 120 is a trained model that has been trained using a general-purpose trained model generation application to read letters or numbers indicating the ratings for each item from an equipment data sheet. In response to input of an equipment data sheet listing multiple items related to a motor to be installed in a plant, the trained model 120 is trained to output letters or numbers indicating the ratings of multiple items related to the motor, associating them with the corresponding items.

The trained model 120 is trained to read letters or numbers indicating the rating when they are written together with symbols indicating units, and to output the read letters or numbers. For example, when the motor's output is 1.2 kW, the output on the equipment data sheet may be written as "1.2," "1.2 kW," "1.2 kW," "1.2 kW," "1.2 (kW)," "1200 W," etc. The motor's voltage may also be written as "400 Volt," "0.4 kV," "400 v," etc. The trained model 120 is trained to read letters or numbers indicating the rating from a string of symbols containing letters and numbers written as the motor's output, voltage, etc. ratings, and to output the read letters or numbers in association with the item name indicating the motor's rating.

The trained model 120 is also trained to read the letters or numbers indicating the rating when they are surrounded by a circle, a square, or a cloud mark, and when a circle, a cross, or a check mark is placed near the numbers indicating the rating. The trained model 120 is trained to read the letters or numbers indicating the rating by removing lines placed around and near the letters or numbers indicating the rating as noise.

The trained model 120 is also trained to read letters or numbers indicating an item's rating in association with the item name indicating the item and the symbol indicating the unit of the item's rating. For example, when the item name indicating the motor's output is "Rated Output (kW)" and the rated unit of the motor's output is "kW," the trained model 120 reads the number written between "Rated Output (kW)" and "kW." By training the trained model 120 to read letters or numbers indicating the rating in association with the item name and the symbol indicating the unit, it is possible to read the number string associated with the item name and the symbol indicating the unit from multiple character strings or number strings written near the item name.

The trained model 120 is also trained to read the letters or numbers indicating the rating when there is a writing area, such as a "free entry field," where a string of characters or numbers may be placed near the letters or numbers indicating the rating, regardless of whether the string of characters is placed in the writing area. The trained model 120 is trained using equipment data sheets in which strings of characters are placed in the writing area and equipment data sheets in which strings of characters are not placed in the writing area as training data.

In addition, the trained model 120 is trained using equipment data sheets that simulate vendor modifications and equipment data sheets that simulate low-quality scans as training data.

The server storage unit 12 also stores the rating information 121 acquired by executing the rating information acquisition process. The server storage unit 12 categorizes and stores the rating information 121 for each target plant of the construction project and for each motor installed in each plant.

Figure 3 shows an example of a directory structure for storing rating information 121.

Rating information 121 is stored in multiple plant directories 1210 for each plant that is the target of the construction project. The plant directory 1210 has a motor directory that stores the rating information 121 for each motor installed in the plant. In the example shown in Figure 3, the plant directory 1210 has n directories, a first motor directory 1211 to an nth motor directory 121n, corresponding to each of the n motors installed in the plant.

Each of the first motor directory 1211 through the nth motor directory 121n stores rating information 121 corresponding to each version of the revised equipment data sheet. Equipment data sheets submitted by motor vendors list multiple items for each of the multiple motors installed in a plant, with letters or numbers indicating the rating along with the item name. If any of the multiple items do not meet the required conditions, a revised version of the equipment data sheet is created in which the item that does not meet the plant's required conditions is corrected. Therefore, the frequency and number of revisions created increases depending on the number of motors installed in the plant. In Figure 3, the first motor directory 1211 stores three pieces of rating information 121, first version information 1211a through third version information 1211c, as the first revised version through the third revised version. Furthermore, the nth motor directory 121n stores two pieces of rating information 121, first version information 121na and second version information 121nb, as the first revised version and the second revised version.

Figure 4 shows the table structure of the first version information 1211a stored in the first motor directory 1211. The rating information 121 stored in the server storage unit 12 has the same table structure as the first version information 1211a.

The first version information 1211a has an identifier column 121a, an item name column 121b, and a rating column 121c. The identifier column 121a contains identifiers E001 to E033 corresponding to items. The number of identifiers included in the identifier column 121a is determined appropriately depending on the number of items required for the plant.

The item name column 121b stores the item name, which is the name of the item, and the rating column 121c stores the item rating. The item names stored in the item name column 121b and the ratings stored in the rating column 121c are stored in association with identifiers E001 to E033, respectively.

(Rating Information Acquisition Process Executed by the Equipment Data Determination System According to the First Embodiment)
Fig. 7 is a sequence diagram of the rating information acquisition process executed by the equipment data determination system 1. The rating information acquisition process shown in Fig. 7 is executed mainly by the server calculation unit 15 and the terminal calculation unit 25 in cooperation with each element of the equipment data determination system 1, based on programs stored in advance in the server storage unit 12 and the terminal storage unit 22.

First, the server acquisition unit 151 sends a device data sheet transmission request to the device data determination device 3, indicating an instruction to transmit a device data sheet (S101). In response to the transmission of the device data sheet transmission request, the terminal acquisition unit 251 determines whether a new device data sheet is stored in a specified new data sheet storage directory. When the terminal acquisition unit 251 determines that a new device data sheet is not stored in the new data sheet storage directory, it sends a response to the data sheet acquisition device 2 indicating that a device data sheet is not stored. Thereafter, the processing of S101 is repeated until the terminal acquisition unit 251 determines that a new device data sheet is stored in the new data sheet storage directory.

When the terminal acquisition unit 251 determines that a new device data sheet is stored in the new data sheet storage directory, it transmits the newly stored device data sheet in the new data sheet storage directory to the data sheet acquisition device 2 (S102). The server acquisition unit 151 acquires the transmitted device data sheet and stores the acquired device data sheet in the server storage unit 12.

Next, the server reading unit 152 inputs the equipment data sheet stored in the server memory unit 12 by the server acquisition unit 151 into the trained model 120 and reads out the rating information 121 (S103). In response to the equipment data sheet being input by the server reading unit 152, the trained model 120 associates letters or numbers indicating the rating for each item from the equipment data sheet with the corresponding item and outputs them as the rating information 121.

Next, the server reading unit 152 acquires the rating information 121 output from the trained model 120 (S104) and stores the acquired rating information 121 in the server storage unit 12. The server reading unit 152 references the location within the plant stored in association with identifier E001 of the acquired rating information 121 and the version associated with identifier E003, and stores the rating information 121 in a specified directory with a name corresponding to the version.

Next, the server transmission unit 153 transmits the rating information 121 acquired in the processing of S104 to the equipment data determination device 3 that sent the equipment data sheet transmission request in the processing of S101 (S105). The server transmission unit 153 transmits the rating information 121 stored in the server memory unit 12 in the processing of S104 to the equipment data determination device 3.

Then, the terminal acquisition unit 251 acquires the rating information 121 transmitted in the processing of S105 (S106) and stores the acquired rating information 121 in the terminal storage unit 22. The terminal acquisition unit 251 references the location within the plant stored in association with identifier E001 of the acquired rating information 121 and the version associated with identifier E003, and stores the rating information 121 in a specified directory with a name corresponding to the version.

(Device Data Determination Process Executed by Device Data Determination Device According to First Embodiment)
Fig. 8 is a flowchart of the device data determination process executed by the device data determination device 3. The device data determination process shown in Fig. 8 is executed mainly by the terminal calculation unit 25 in cooperation with each element of the device data determination device 3, based on a program stored in advance in the terminal storage unit 22.

First, the terminal acquisition unit 251 acquires an equipment data determination instruction (S201). The equipment data determination instruction is input via the terminal input unit 23 by the designer operating the equipment data determination device 3. The equipment data determination instruction includes an execution instruction to execute the equipment data determination process, as well as a table generation instruction that specifies the table information to be generated. The table generation instruction includes a target equipment table instruction to generate target equipment table information that includes equipment data determination results for multiple target motors, and a revision history table instruction to generate revision history table information that includes equipment data for a single motor in revision order.

Next, the terminal acquisition unit 251 acquires the rating information 220 stored in the terminal storage unit 22 (S202). When the equipment data determination instruction acquired in the processing of S201 includes a target equipment table instruction, the terminal acquisition unit 251 acquires the latest version of the rating information 220 stored in the first motor directory. When the equipment data determination instruction acquired in the processing of S201 includes a revision history table instruction, the terminal acquisition unit 251 acquires all of the rating information 220 stored in the motor directory corresponding to the motor for which the revision history table is to be generated.

Next, the terminal acquisition unit 251 acquires the condition information 221 stored in the terminal storage unit 22 (S203).

Next, the terminal comparison unit 252 determines whether the rating indicated by the rating information 220 for each item satisfies the condition indicated by the condition information 221 (S204). The terminal comparison unit 252 compares the characters stored in the rating column in association with identifier E004 of the rating information 121 with the characters stored in the condition column 221c in association with identifier C001 of the condition information 221. When the terminal comparison unit 252 determines that the characters "outdoor" stored in association with identifier E004 match the characters "outdoor" stored in association with identifier C001 (S204-YES), it adds the code "0" (S205).

Figure 9 shows the first version of the information after steps S204 to S207 have been executed, Figure 10 shows the second version of the information after steps S204 to S207 have been executed, and Figure 11 shows the third version of the information after steps S204 to S207 have been executed.

As steps S204 to S207 are executed, a display change code field 121d is added to the first version information 1211a, second version information 1211b, and third version information 1211c. The display change code field 121d stores a one-bit code, either "0" indicating that the condition is met or "1" indicating that the condition is not met, associated with each of the identifiers E001 to E033.

In the first version information 1211a, the display change code associated with the identifiers "E012," "E021," and "E022" is "1," while the display change code associated with the other identifiers is "0." The item name "Locked Rotor current (%)" associated with identifier "E012" stores "750," which is greater than the "700" stored in the condition column 221c of the condition information 221, and therefore has a display change code of "1." The item name "No. of successive start in hot" associated with identifier "E021" stores "1," which is less than the "2" stored in the condition column 221c of the condition information 221, and therefore has a display change code of "1." The item name "No. of successive start in cool" associated with identifier "E022" stores "2," which is less than the "3" stored in the condition column 221c of the condition information 221, and therefore has a display change code of "1."

In the second version information 1211b, the display change code associated with the identifiers "E012" and "E025" is "1", and the display change code associated with the other identifiers is "0". The item name "Locked Rotor current (%)" associated with the identifier "E012" has a display change code of "1" because "750" is stored in the condition column 221c of the condition information 221, which is greater than the "700" stored in the condition column 221c. The item name "Noise (dB)" associated with the identifier "E025" has a display change code of "1" because "90" is stored in the condition column 221c of the condition information 221, which is greater than the "85" stored in the condition column 221c.

In the third version information 1211c, all items satisfy the conditions set forth in the condition information 221, so the display change code associated with all identifiers is "0".

When the terminal comparison unit 252 determines that the determination process of S204 has been performed for all items (S207-YES), the terminal generation unit 253 determines whether to display the revision history table (S208). When the device data determination instruction acquired in the process of S201 includes a revision history table instruction, the terminal generation unit 253 determines to display the revision history table (S208-YES). When the device data determination instruction acquired in the process of S201 includes a target device table instruction, the terminal generation unit 253 determines to display the target device table (S208-NO).

When the terminal generation unit 253 determines that the target device table should be displayed (S208-NO), it determines whether or not the processes of S202 to S206 have been executed for all target devices (S209). The processes of S202 to S208 are repeated until the terminal generation unit 253 determines that the processes of S202 to S206 have been executed for all target devices (S209-YES).

When the terminal generation unit 253 determines that the processes of S202 to S206 have been executed for all target devices (S209-YES), it generates target device table information indicating a target device table (S210) and stores the generated target device table information in the terminal storage unit 22. The target device table information is an example of determination information indicating whether the characters or numbers indicated by the rating information 220 satisfy the conditions indicated by the condition information 221. The terminal generation unit 253 generates the target device table information so that the display mode of characters or numbers that do not satisfy the conditions indicated by the condition information 221 differs from the display mode of characters or numbers that satisfy the conditions.

Next, the terminal output unit 254 outputs the target device table information generated in the processing of S210 to the terminal display unit 24 (S211). The terminal display unit 24 displays a target device table corresponding to the target device table information input from the terminal output unit 254.

Figure 12 shows an example of a target device table displayed on the terminal display unit 24.

The target equipment table 222 is an example of a judgment table, and has an item name column 2220, a condition column 2221, and first motor columns 2222 to sixth motor columns 2227. The item name column 2220 stores the item name, and the condition column 2221 stores the conditions for each item. The first motor column 2222 to sixth motor column 2227 store the ratings stored in the first motor directory to sixth motor directory, respectively.

In the target equipment table 222, the "Locked Rotor current (%)" ratings in the second motor column 2223 and fifth motor column 2226 do not satisfy the conditions stored in the condition column 2221. Furthermore, the "Degree of Protection" and "Starting Method" ratings in the fourth motor column 2225 and the "Insulation Class" rating in the sixth motor column 2227 do not satisfy the conditions stored in the condition column 2221. The display mode of ratings that do not satisfy the conditions stored in the condition column 2221 differs from the display mode of ratings that satisfy the conditions stored in the condition column 2221.

When the terminal generation unit 253 determines that the revision history table should be displayed (S208-YES), the terminal comparison unit 252 determines whether the item's rating has changed from the version before the revision (S212). The terminal comparison unit 252 determines that there have been no changes since the first version information 1211a is the first version (S213-NO) and adds a "0" to the code stored in the display change column associated with identifier E004 of the first version information 1211a, changing it to "00". Next, the terminal comparison unit 252 determines whether the determination shown in S212 has been performed for all versions (S215). If the terminal comparison unit 252 determines that the determination shown in S212 has not been performed for all versions (S215-NO), processing returns to S212. Next, the terminal comparison unit 252 compares the characters stored in the rating column in association with the identifier E004 of the first version information 1211a with the characters stored in the rating column in association with the identifier E004 of the second version information 1211b. If the terminal comparison unit 252 determines that the characters stored in association with the identifier E004 of the first version information 1211a match the characters stored in association with the identifier E004 of the second version information 1211b (YES in S212), it adds a code "0" to the change display column (S213). If the terminal comparison unit 252 determines that the characters stored in association with the identifier E004 of the first version information 1211a do not match the characters stored in association with the identifier E004 of the second version information 1211b (NO in S212), it adds a code "1" to the change display column (S214). Thereafter, steps S212 to S215 are repeated until the terminal comparison unit 252 determines that the determination shown in step S212 has been performed for all versions (YES in step S215).

When the terminal comparison unit 252 determines that the determination shown in S212 has been performed for all versions (S215-YES), it determines whether all items have been determined (S216). The processes of S212 to S216 are repeated until the terminal comparison unit 252 determines whether all items have been determined (S216-YES).

Figure 13 shows the first version of the information after steps S212 to S216 have been executed, Figure 14 shows the second version of the information after steps S212 to S216 have been executed, and Figure 15 shows the third version of the information after steps S212 to S216 have been executed.

As the processes of S212 to S216 are executed, 2-bit codes are stored in the display change code column 121d of the first version information 1211a, second version information 1211b, and third version information 1211c in association with each of the identifiers E001 to E033. The code "00" stored in the display change code column 121d indicates that the conditions are met and the rating has not been changed by the revision, the code "01" indicates that the conditions are not met and the rating has not been changed by the revision, the code "10" indicates that the conditions are met and the rating has been changed by the revision, and the code "11" indicates that the conditions are not met and the rating has been changed by the revision.

In the first version information 1211a, the display change code associated with the identifiers "E012," "E021," and "E022" is "01," and the display change code associated with the other identifiers is "00." Since the first version information 1211a is the first version, all of the second bit codes are "0."

In second version information 1211b, the display change code associated with identifier "E012" is "01", and the display change code associated with "E021" and "E022" is "10". The display change code associated with identifier "E025" is "11", and the display change code associated with the other identifiers is "00". The rating associated with identifier "E012" has not been modified and does not satisfy the conditions set forth in condition information 221, so the display change code is "01". The ratings associated with "E021" and "E022" have been modified to satisfy the conditions set forth in condition information 221, so the display change code is "10". The rating associated with "E025" has been modified to not satisfy the conditions set forth in condition information 221, so the display change code is "11".

In third edition information 1211c, the display change code associated with identifiers "E012" and "E025" is "10," and the display change code associated with other identifiers is "00." The ratings associated with identifiers "E012" and "E025" have been modified to satisfy the conditions set forth in condition information 221, so the display change code is "10."

When the terminal comparison unit 252 determines whether all items have been determined (S216-YES), the terminal generation unit 253 generates revision history table information indicating a revision history table (S217) and stores the generated revision history table information in the terminal storage unit 22. The revision history table information is another example of determination information indicating whether the characters or numbers indicated by the rating information 220 satisfy the conditions indicated by the condition information 221. The terminal generation unit 253 generates the revision history table information so that, in the revision history table information, the display mode of characters or numbers that do not satisfy the conditions indicated by the condition information 221 differs from the display mode of characters or numbers that satisfy the conditions. In addition, the terminal generation unit 253 generates the revision history table information so that, in the revision history table information, the display mode of the characters or numbers corresponding to items whose ratings have been changed by revision differs from the display mode of the characters or numbers corresponding to items whose ratings have not been changed by revision. Furthermore, the terminal generation unit 253 generates revision history table information so that when letters or numbers corresponding to items whose ratings have been changed due to revisions on the equipment data sheet do not satisfy the above conditions, the letters or numbers are displayed in a manner indicating that the conditions are not satisfied.

Next, the terminal output unit 254 outputs the revision history table information generated in the processing of S217 to the terminal display unit 24 (S218). The terminal display unit 24 displays a revision history table corresponding to the revision history table information input from the terminal output unit 254.

Figure 16 shows an example of a revision history table displayed on the terminal display unit 24.

The revision history table 223 is another example of a judgment table, and has an item name column 2230, a condition column 2231, and first version columns 2232 to third version columns 2235. The item name column 2230 stores the item name, and the condition column 2231 stores the conditions for each item. The first version columns 2232 to third version columns 2234 each store the rating stored in the first motor directory.

The ratings of "Locked Rotor current (%)," "Number of successive starts in hot," and "Number of successive starts in cool" in the first version column 2232, and "Locked Rotor current (%)" and "Noise (dB)" in the second version column 2233, do not satisfy the conditions stored in the condition column 2221. In addition, the ratings of "Number of successive starts in hot," "Number of successive starts in cool," and "Noise (dB)" in the second version column 2233, and "Locked Rotor current (%)" and "Noise (dB)" in the third version column 2234 will be changed.

The display mode of a rating that does not satisfy the conditions stored in the condition column 2221 differs from the display mode of a rating that satisfies the conditions stored in the condition column 2221. The display mode of a rating whose rating will be changed by revision differs from the display mode of a rating whose rating will not be changed by revision. The display mode of the "Noise (dB)" rating in the second version column 2233, which does not satisfy the conditions stored in the condition column 2221 and whose rating will be changed by revision, is the same as the display mode of other ratings that do not satisfy the conditions stored in the condition column 2221.

(Data Conversion Process Executed by the Device Data Determination Device According to the First Embodiment)
Fig. 17 is a flowchart of the data conversion process executed by the device data determination device 3. The data conversion process shown in Fig. 17 is executed mainly by the terminal calculation unit 25 in cooperation with each element of the device data determination device 3, based on a program stored in advance in the terminal storage unit 22.

First, the terminal conversion unit 255 acquires the rating information 220 stored in the terminal storage unit 22 (S301). Next, the terminal conversion unit 255 converts the rating information 220 acquired in the process of S301 into a predetermined format (S302). For example, the terminal conversion unit 255 converts the rating information 220 into a format that can be read by a design tool such as Smart Plant Electrical (SPEL). Then, the terminal conversion unit 255 stores the rating information 220, whose format has been converted in the process of S302, in the terminal storage unit 22 (S303).

(Operational effects of the device data determination system according to the first embodiment)
The equipment data determination system 1 can reduce the time required to review equipment data sheets by making it possible to display determination information indicating whether the ratings indicated by the rating information 220 for each item satisfy the conditions indicated by the condition information 221. By using the equipment data determination system 1, the time required to review equipment data sheets can be reduced by 40%. The equipment data determination system 1 automatically determines whether the equipment data sheets of over 1,000 motors installed in a plant satisfy the conditions required by the plant, thereby significantly reducing the burden on designers.

In addition, the equipment data determination system 1 reads numbers from equipment data sheets using a trained model that has been trained using various equipment data sheets with different display modes for the numbers indicating the ratings as training data, allowing it to read numbers indicating the ratings with high accuracy. Furthermore, the numbers indicating the ratings read as rating information 221 by the equipment data determination system 1 can be used, for example, when setting the operating values of a protective relay that protects a motor. Because the equipment data determination system 1 can automatically read numbers that can be used when setting the operating values of a protective relay, the burden on designers can be reduced.

The equipment data determination system 1 also generates target equipment table information and revision history table information that can display letters or numbers that do not satisfy a condition in a different manner from letters or numbers that do satisfy the condition. The table information generated by the equipment data determination system 1 displays letters or numbers differently depending on whether the condition is satisfied, allowing designers to easily visually identify letters or numbers that do not satisfy the condition, reducing the time required to review equipment data sheets. Furthermore, the target equipment table 222 and revision history table 223 generated by the equipment data determination system 1 allow easy visual identification of letters or numbers that do not satisfy the condition, preventing designers from missing checks or forgetting to revise items.

In addition, the equipment data determination system 1 stores rating information corresponding to the revised version each time an equipment data sheet is revised in a displayable manner, allowing designers to easily manage the revision history of equipment data sheets. The equipment data determination system 1 also generates revision history table information that enables the display of letters or numbers whose ratings have been changed due to revisions to be displayed differently from the display of letters or numbers whose ratings have not been changed due to revisions. The revision history table information generated by the equipment data determination system 1 displays differently depending on whether the rating has been changed due to revisions, allowing designers to easily visually identify letters or numbers whose ratings have been changed due to revisions, reducing the time required to review equipment data sheets.

In addition, the equipment data determination system 1 generates revision history table information that can be displayed so that when letters or numbers corresponding to an item whose rating has been changed due to a revision do not meet the conditions, the letters or numbers are displayed in a manner indicating that the conditions are not met. In the revision history table information generated by the equipment data determination system 1, letters or numbers whose rating has been changed due to a revision and that do not meet the conditions are displayed in a manner indicating that the conditions are not met, so that designers can easily visually recognize letters or numbers that do not meet the conditions.

In addition, the equipment data determination system 1 can convert rating information into a specified format, so the rating information 220 read from the equipment data sheet can be converted so that it can be read by specified tools such as design tools, and can be used in a variety of tools.

(Configuration and Functions of Datasheet Acquisition Apparatus According to Second Embodiment)
The data sheet acquisition device 2a differs from the data sheet acquisition device 2 in that it has a server storage unit 12a and a server calculation unit 15a instead of the server storage unit 12 and the server calculation unit 15. The configurations and functions of the components of the data sheet acquisition device 2a other than the server storage unit 12a and the server calculation unit 15a are the same as the configurations and functions of the components of the data sheet acquisition device 2 that are assigned the same reference numerals, and therefore detailed explanations thereof will be omitted here.

Server storage unit 12a differs from server storage unit 12 in that it has trained model 122 instead of trained model 120. The configuration and functions of server storage unit 12a other than trained model 122 are the same as those of server storage unit 12, so a detailed description will be omitted here.

The trained model 122 includes a vendor trained model 1220 and n first read trained models 1221 to nth read trained models 122n. The vendor trained model 1220 is a trained model that is pre-trained by supervised learning. The vendor trained model 1220 is a trained model that is trained using equipment data sheets submitted by multiple vendors as training data, and in response to input of an equipment data sheet, outputs vendor name information indicating the name of the vendor that submitted the input equipment data sheet. The vendor trained model 1220 is trained using equipment data sheets that include the vendor's trademark as training data.

Each of the first read-trained model 1221 to the nth read-trained model 122n is a training model that is pre-trained by supervised training, similar to trained model 120. In response to input of an equipment data sheet submitted by the corresponding vendor, each of the first read-trained model 1221 to the nth read-trained model 122n associates letters or numbers indicating the rating for each specified item with the corresponding item and outputs the rating information 121.

Server calculation unit 15a differs from server calculation unit 15 in that it has a server reading unit 152a instead of server reading unit 152. Server calculation unit 15a also differs from server calculation unit 15 in that it has a server estimation unit 154. The configurations and functions of the components of server calculation unit 15a other than server reading unit 152a and server estimation unit 154 are assigned the same reference numerals, but are the same as the configurations and functions of the components of server calculation unit 15, so detailed explanations will be omitted here.

(Rating Information Acquisition Process Executed by the Equipment Data Determination System According to the Second Embodiment)
Fig. 19 is a sequence diagram of the rating information acquisition process executed by the equipment data determination system according to the second embodiment. The rating information acquisition process shown in Fig. 19 is executed mainly by the server calculation unit 15 and the terminal calculation unit 25 in cooperation with the various elements of the equipment data determination system 1, based on programs stored in advance in the server storage unit 12 and the terminal storage unit 22. The processes of S401 and S402 are similar to the processes of S101 and S102, and therefore will not be described in detail here.

Following the processing of S402, the server estimation unit 154 inputs the equipment data sheet stored in the server memory unit 12 by the server acquisition unit 151 into the vendor trained model 1220 (S403). In response to the equipment data sheet being input by the server estimation unit 154, the vendor trained model 1220 outputs vendor name information indicating the name of the vendor that submitted the input equipment data sheet. The server estimation unit 154 stores the vendor name information output from the vendor trained model 1220 in the server memory unit 12a.

Next, the server reading unit 152a selects a read-trained model to use for reading the equipment data sheet based on the vendor name information stored in the process of S203 (S404). Depending on the vendor estimated in the process of S403, one of multiple read-trained models, the first read-trained model 1221 to the nth read-trained model 122n, is selected. Specifically, the server reading unit 152a selects from the first read-trained model 1221 to the nth read-trained model 122n the read-trained model associated with the vendor name corresponding to the vendor name information stored in the process of S403.

The server reading unit 152a then inputs the equipment data sheet stored in the server storage unit 12 by the server acquisition unit 151 into the read-trained model selected in the process of S203 to read the rating information 121 (S405). In response to the equipment data sheet being input by the server reading unit 152a, the read-trained model selected in the process of S403 associates letters or numbers indicating the rating for each item from the equipment data sheet with the corresponding item and outputs them as rating information 121. Next, the server reading unit 152a uses the read-trained model selected in the process of S403, i.e., acquires the rating information 121 output from the read-trained model selected in the process of S403 (S406). The processes of S406 to S408 are similar to the processes of S104 to S106, and therefore will not be described in detail here.

(Operational effects of the device data determination system according to the second embodiment)
The equipment data determination system according to the second embodiment estimates the vendor that provided the equipment data sheet, making it possible to read rating information from equipment data sheets provided by various vendors. The equipment data determination system according to the second embodiment can read rating information in a single format from equipment data sheets provided by various vendors, preventing designers from missing checks and reducing review efficiency. Furthermore, the equipment data determination system according to the second embodiment can more accurately read rating information from equipment data sheets by using a different read-trained model for each vendor.

(Modification of the device data determination system according to the embodiment)
In the described equipment data determination system, target equipment table information and revision history table information showing tables are generated as determination information, but the equipment data determination system according to the embodiment may generate determination information that can be displayed in a display format other than a table. For example, in the equipment data determination system according to the embodiment, the determination information may display only letters or numbers indicating ratings that do not satisfy the conditions, in association with the corresponding items.

In addition, in the described equipment data determination system, the target equipment table information and revision history table information change the display mode of the character or number area, but the equipment data determination system according to the embodiment may change other display modes. For example, the equipment data determination system according to the embodiment may change the color, font, etc. of characters or numbers that do not meet the conditions or whose ratings have been changed due to revision, or may change the color or thickness of the line surrounding the area where characters or numbers that do not meet the conditions or whose ratings have been changed due to revision are located.

Furthermore, in the equipment data determination system described above, the target equipment table information and revision history table information are displayed as one-way tables that change the display format, but in the equipment data determination system according to the embodiment, a two-way table that can be input by the designer may also be displayed.

Figure 20 shows a revision history table corresponding to the revision history table information for the modified example.

The revision history table 224 has a comment field 2240 where the designer can enter comments. The comment field 2240 is stored in association with an identifier corresponding to the letters or numbers of the items that do not meet the conditions, and is displayed corresponding to the letters or numbers of the items that do not meet the conditions.

In response to the designer entering letters or numbers into the comment field 2240, the terminal computing unit 25 stores input information indicating the letters or numbers entered into the comment field 2240 in association with an identifier associated with the comment field 2240. In response to receiving a comment output instruction to output a comment, the terminal computing unit 25 outputs the letters or numbers corresponding to the input information as text data together with the corresponding item and letters or numbers. The terminal computing unit 25 may also output a tabular sheet containing the comments entered into the revision history table 224 as an electronic file.

In the modified example described with reference to Figure 20, the designer manually inputs comments, but the terminal calculation unit 25 may automatically generate and output text data indicating the rating that should be set according to the condition information for items that do not satisfy the conditions.

The equipment data determination device 2 also determines the vendor that provided the equipment data sheet by inputting the equipment data sheet into the vendor trained model 1220. However, the equipment data determination device 2 according to the embodiment may determine the vendor that provided the equipment data sheet without using the vendor trained model 1220. For example, the equipment data determination device 2 according to the embodiment may recognize the vendor's trademark listed on the equipment data sheet and determine the vendor that provided the equipment data sheet based on the recognized trademark.
