Description

  The present invention relates to a technique for supporting program modification. In particular, the present invention relates to a technique for supporting program modification of inspection / repair work (inspection work) in a railway vehicle.

  In inspection work on railway vehicles, inspection results for specific inspections are used for other inspections, so the inspection work system has a program structure (link relationship) in which variables relating to inspection items are linked and linked in a complex manner. .

  Conventionally, techniques disclosed in Patent Documents 1 and 2 have been proposed as techniques for supporting modification of a program having such a complicated link relationship. Patent Document 1 discloses a technique for converting a data link relationship into a hierarchical structure and storing it in a storage device. Patent Document 2 discloses a technique for specifying a range in which a correction part affects when a program is corrected.

Japanese Patent Application No. 8-310544 Japanese Patent Application 5-121405

  However, Patent Document 1 discloses a technique for displaying a link relation of data stored in a storage device, but does not consider a technique for specifying an influence range associated with program correction.

  Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for specifying an influence range associated with program correction, but does not disclose a technique for specifying the order of program correction work.

  For example, in a business system for inspection work in a railway vehicle, inspection items for inspection work maintain a linked relationship according to a work flow (screen hierarchy). In this case, it is necessary to consider the modification order when modifying the business system program.

  Therefore, in the present invention, the interlocking relationship of the inspection items (data items) between the layers of each screen of the business system is stored, and the screen of the layer to be corrected is specified based on this interlocking relationship. When the setting information about the data item included in the screen of the predetermined hierarchy is corrected, the data item of the other hierarchy linked with the corrected data item is specified. If the identified data item is included across multiple levels of screens, the screen of the level closest to the corrected level is specified, and a screen that prompts a data item correction instruction is displayed.

  According to the present invention, it is possible to sequentially modify the affected part by identifying the affected part due to the partial correction of the program according to the business flow (the hierarchical structure of the screen), so the program is modified while maintaining data consistency. It is possible to provide a program modification support means for executing.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a system configuration diagram of a program modification support system according to the present embodiment. The program modification support system includes a server 10, a management terminal 20, a master DB 30, and an inspection performance DB 40. Each computer (server, terminal, DB) is connected to each other via a network. Each computer has a processing device such as a memory, a storage device including a hard disk, and a CPU, and the processing device executes information processing according to a program stored in the storage device.

  The system administrator operates the management terminal 20 connected to the server 10 to execute a program modification process in the railway vehicle inspection and repair business system. The master DB 30 provided in the server 10 stores program setting data for the inspection work system. The server 10 corrects the setting data of the master DB 30 based on the information transmitted from the management terminal 20, and generates a modified program using the corrected setting data.

  FIG. 2 is a conceptual diagram showing an example of screen transition of a business screen in a railway vehicle inspection and repair business system. The transition (link) relationship for each screen is shown in a hierarchical diagram, and indicates that the screen from level 1 to level 5 is displayed in order. For example, it is indicated that a transition (link) from the selection screen of layer 1 to any one of the three screens of the A report screen, the B report screen, and the C report screen of layer 2 is performed.

  FIG. 3 is a conceptual diagram illustrating an example of a display screen of a business flow in the railway vehicle inspection and repair system. Here, an example of a display screen in a series of screen transitions from the C report screen 510 in FIG. 2 to the FF inspection screen 520, the MM inspection screen 530, and the NN inspection result screen 540 is shown. In FIG. 3, data of the inspection result of each inspection item is input in the input column. For example, it is assumed that the measured value (wheel width) of the C device (wheel) on the C report screen 510 is input. In addition, some of the data (inspection item data) in the inspection item input field between the screens is linked. For example, in the inspection item data of the part C on the FF inspection screen 520, the condition (linkage condition) specified in advance by the system based on the value input as the inspection item data of the C device (1) on the C report screen 510 The result calculated according to) is output. Similarly, the inspection item data of the inspection result C on the NN inspection result screen 540 includes the result calculated based on the inspection item data of the C device (2) on the C report screen 510 and the part C on the FF inspection screen 520. Is output.

  FIG. 4 is a conceptual diagram showing the interlocking relationship of the inspection item data in FIG. 3 for each screen. For example, it indicates that the inspection item data on the screen of level 2 is linked with the inspection item data of levels 3 to 5.

  5 to 11 are diagrams showing examples of display screens in the program modification support system for modifying the program of the railway vehicle inspection and repair business system described in FIGS. 2 to 4 (changing the inspection work). . Each screen is displayed on the management terminal 20, and the system administrator operates according to these screens to cause the server 10 to execute a program modification process (an inspection work change process).

  FIG. 5 shows a first menu selection screen for the inspection work change process. In the present embodiment, the repair work change process indicates three types of processes: addition of a screen holding inspection item data (screen addition process), modification (screen modification process), and deletion (screen deletion process). The menu selection screen in FIG. 5 is a screen for selecting a menu to be executed from among these three types of processing.

  FIG. 6 is a screen for selecting the position of the screen to be added when the screen addition process is executed (an inspection work addition screen). On the inspection work addition screen, a list of screens constituting a specific business flow is displayed for each layer. The system administrator inputs the name and position of the screen to be added.

  FIG. 7 is a screen for selecting a screen to be corrected when executing screen correction processing (an inspection operation selection screen). The system administrator selects a screen including the inspection item to be corrected.

  FIG. 8 is a screen for selecting a screen to be deleted when the screen deletion process is executed (an inspection screen deletion screen). The system administrator selects a screen to be deleted.

  9 and 10 are screens for correcting the inspection items included in the screen after the screen to be corrected is selected when executing the screen correction processing. The system administrator changes the name, type, and number of digits of the inspection item on the inspection item correction screen in FIG. 9, and the maximum and minimum values that can be entered in the inspection item on the reference value correction screen in FIG. change.

  FIG. 11 is a screen for changing the inspection item interlocking relationship and interlocking conditions common to all processing of the screen addition processing, screen correction processing, and screen deletion processing. For example, the linkage destination “DS-004 inspection item 2” indicates a value obtained by calculating the linkage source 1 “DS-004 inspection item 1” and “DS-004 inspection item 2” with the linkage condition “AND”. The system administrator changes the inspection item and the interlocking condition of the interlocking source and the interlocking destination.

  FIG. 12 to FIG. 18 are diagrams showing configuration examples of the data table in the system of the present embodiment. The data table stores the setting information of the inspection work system program in the railway vehicle, and the program can be automatically generated based on the setting information. Therefore, when changing the program, the setting information is corrected, and a program based on the corrected setting information is generated.

  FIG. 12 is a diagram illustrating a configuration example of the screen hierarchy master table of the master DB. The screen hierarchy master table stores information indicating the screen hierarchy structure for each business flow. In this example, for example, information indicating that the business flow identified by the business flow ID “A” is composed of five screens from layer 1 to layer 5 is stored.

  FIG. 13 is a diagram illustrating a configuration example of the inspection item master table of the master DB. In the inspection item master table, information indicating inspection items included in each screen is stored. In this example, for example, the screen “FF inspection screen” specified by the screen ID “DS-003” stores information indicating that four examination items A to D are included.

  FIG. 14 is a diagram illustrating a configuration example of a reference value master table of the master DB. The reference value master table stores information indicating the maximum value and the minimum value that can be input to the inspection item for each screen. In this example, for example, information indicating the maximum value and the minimum value of four inspection items included in the screen specified by the screen ID “DS-003” is stored.

  FIG. 15 is a diagram illustrating a configuration example of a master master interlocking master table. The linkage master table stores information indicating the linkage relationship between the inspection items and the linkage conditions. In this example, for example, the linkage destination “DS-004 inspection item 2” is a value calculated from the linkage source 1 “DS-004 inspection item 1” and “DS-004 inspection item 2” according to the linkage condition “AND”. Is stored.

  FIG. 16 is a diagram illustrating a configuration example of a condition master table of the master DB. The condition master table stores information indicating the definition of the interlocking condition. In this example, for example, “MAX” stores information indicating that a value indicating the maximum value of a plurality of inspection items is calculated.

  FIG. 17 is a diagram illustrating a configuration example of the inspection performance table of the inspection performance DB. The past change history information is stored in the inspection result table.

  FIG. 18 is a diagram illustrating a configuration example of a data table temporarily stored in a storage device as a temporary storage table.

  FIG. 19 and FIG. 20 are flowcharts showing the procedure of the inspection work change process in the program modification system. Hereinafter, the procedure of the inspection work change process will be described with reference to FIGS. 19 and 20.

  First, in step 201, the server 10 transmits the inspection work change menu screen information to the management terminal 20, and causes the display device 21 to display the inspection work change menu screen 100 shown in FIG. The system administrator selects the business flow ID from the displayed repair work change menu screen 100 and presses the correction button.

  In step 202, the server 10 receives the information 101 of the business flow ID selected on the inspection work change menu screen and button operation information. The operation information is information for selecting one of “screen addition processing”, “screen correction processing”, and “screen deletion processing”. In this example, it is assumed that the business flow ID “A” is received.

  In step 203, if the button operation information indicates "screen addition process", the process proceeds to step 204. If "button modification process" is indicated, the process proceeds to step 209. If "button deletion process" is indicated, the process proceeds to step 225. . First, the procedure when “screen correction processing” is shown will be described.

  In step 209, the server 10 searches and extracts information in the screen hierarchy master table 31 based on the received business flow ID. In this example, information “DS-001” to “DS-005” of five screens from the hierarchy 1 to the hierarchy 5 specified by the business flow ID “A” is extracted. Next, the server 10 transmits the inspection work selection screen 120 on which the extracted information is displayed to the management terminal 20 for display. The system administrator selects a screen including the inspection item to be changed from the inspection work selection screen 120 displayed. In this example, it is assumed that the inspection screen “(2)” is selected.

  In step 210, the server 10 receives the data of the inspection screen information “(2)” 121 selected in step 209 from the management terminal 20.

  In step 211, the hierarchy position “hierarchy 2” and the screen ID “DS” are obtained from the data 310 of the repair screen information “(2)” selected in step 209 and the business flow ID “A” of the screen hierarchy master table 31. -002 "is specified, and the value is stored in the hierarchical position 411 and the screen ID 412 of the temporary storage table [hierarchical position] 410.

  In step 212, the screen ID 412 stored in the temporary storage table [hierarchy position] 410 is compared with the screen ID 320 of the inspection item master, and the inspection item data 321 corresponding to “DS-002” is extracted.

  In step 213, the server 10 transmits the inspection item correction screen information and the data 321 extracted in step 212 to the management terminal 20, and causes the display device 21 to display the inspection item correction screen 140. The system administrator operates the inspection item correction screen 140, and the inspection item name 142, inspection item name 3, inspection item 5, inspection item name 142 corresponding to the inspection items 600, 610, and 620 on the inspection screen 510, and the number of types / digits. The change of 143 is performed from the input device 22.

  In step 214, the server 10 receives the data of the inspection item name 142 and the type / digit number 143 input from the contents of the inspection item correction screen 140 from the management terminal 20.

  In step 215, the data received in step 214 is stored in the temporary storage table [inspection item] 420 of the storage device 12.

  In step 216, the inspection item data 321 in the inspection item master table is updated with the data received in step 214.

  In step 217, the screen ID 412 stored in the temporary storage table [hierarchy position] 410 of the storage device 12 is compared with the screen ID 330 of the reference value master table, and the reference value data 331 corresponding to “DS-002” is extracted. To do.

  In step 218, the server 10 transmits the reference value correction screen information and the data 331 extracted in step 217 to the management terminal 20, and causes the display device 21 to display the reference value correction screen 150. The system administrator operates the reference value correction screen 150 and changes the inspection item 1, inspection item 3, inspection item 5, maximum value 151, and minimum value 152 corresponding to inspection item 600, 610, and 620 on the inspection screen 510. From the input device 22.

  In step 219, the server 10 receives data of the maximum value 151 and the minimum value 152 input from the content of the reference value correction screen 150 from the management terminal 20.

  In step 220, the data received in step 219 is updated to reference value data 331 in the reference value master table.

  In step 221, inspection item data 421 (all inspection items: DS-002-inspection item 1, DS-002-inspection item 3, DS-002-inspection item 5) stored in temporary storage table [inspection item] 420 ) Is used as a search key to search all linkage destinations 340 in the linkage master table and extract linkage conditions including the search key.

  In step 222, the server 10 transmits the interlocking condition change screen information and the data extracted in step 221 to the management terminal 20, and causes the display device 21 to display the interlocking condition change screen 160. The system administrator operates the change of the link condition from the link condition change screen 160.

  In step 223, the server 10 receives the data of the interlocking condition 163 and the interlocking source 164 input in the contents of the interlocking condition change screen 160 from the management terminal 20. In this example, there is no linkage to the inspection items (600, 610, 620), so no change is made.

  In step 224, the data received in step 223 is updated to the interlocking master table shown in FIG.

  In step 251, all of the interlocking sources 341 in the interlocking master table are searched using the inspection item 421 stored in the temporary storage table [inspection item] 420 as a search key, and it is determined whether there is data including the search key. When there is no data, since the upper level inspection screen (520, 530, 540) is not affected, the interlocking condition changing process ends.

  In step 252, the search is performed in step 251, and the corresponding interlocking data (700, 710, 730) is extracted and stored in the temporary storage table [interlocking condition] 430. In this example, the inspection item 422 corresponding to the inspection item 620 on the inspection screen 510 is not extracted because it is not included in the interlocking source 341 of the interlocking master table.

  In step 253, refer to the data 310 of the screen hierarchy master table using the screen ID included in the link destination 432 of the data (700, 710, 730) stored in the temporary storage table [link condition] 430 as the search key. The hierarchy position is stored in the previous hierarchy 431.

  In step 254, the server 10 transmits the link condition change screen information and the link data (700, 710, 730) extracted in step 252 to the management terminal 20, and displays the link condition change screen 160 on the display device 21. Display. The system administrator operates the interlocking condition change screen 160 to change the interlocking condition 710 from the input device 22.

  When looping from step 266 and returning to step 254, the server 10 transmits the interlocking condition change screen information and the interlocking data extracted in step 266 to the management terminal 20, and displays the interlocking condition change screen on the display device 21. 160 is displayed.

In step 255, the presence / absence of change is accepted and determined from the button operation information.
If not changed, the process proceeds to step 259. The interlocking condition 163 that can be entered on the interlocking condition change screen is selected from the condition table 350.

  In step 256, the server 10 receives from the management terminal 20 the interlocking condition data 161 changed to the contents of the interlocking condition change screen 160.

  In step 257, the data 161 received in step 256 is updated to the interlocking data 710 in the interlocking master table.

  In step 258, the information of the link destination 165 of the data 161 received in step 256 is stored in the temporary storage table [link destination (1)] 440 and the temporary save table [link destination (2)] 450 of the storage device 12 shown in FIG. To store.

  In step 259, the value “tier 2” 411 stored in the temporary storage table [hierarchy position] 410 is compared with the value 431 of the link destination hierarchy stored in the temporary storage table [hierarchy position] 430. , Update the value of the hierarchy position and the screen ID value with the smallest hierarchy difference. In this example, the value “tier 3” is stored in the layer position 411 and the value “DS-003” is stored in the screen ID 412 from the interlocking condition data 700 having the smallest layer difference.

  In step 260, the value “hierarchy 3” of hierarchy position 411 stored in temporary storage table [hierarchy position] 410 is compared with value 431 of the interlocking destination hierarchy stored in temporary storage table [interaction condition] 430. , Delete the linked data in the temporary storage table [linked condition] 430 with matching values. In this example, the interlocking condition of the interlocking condition data 700 whose values match is deleted from the temporary storage table [interlocking condition].

  In step 261, it is confirmed whether there is data stored in the temporary storage table [interlocking condition] 430. In this example, interlocking condition data (710, 730) exists. If not, go to step 267.

  In step 262, using the value “DS-004-inspection item 2” stored in the temporary storage table [link destination (1)] 440 as a key, the link source 341 of the link master table is extracted, and the temporary save table [ Linked condition] 430. In this example, the link source 720 of the link master table is extracted and added to the temporary storage table [link condition] of the storage device 12 and stored.

  In step 263, the data stored in temporary storage table [link destination (1)] 440 is deleted.

  In step 264, the linked data stored in the temporary storage table [linked condition] 430 is checked for duplication, and the linked data, linked condition, linked condition, and linked source conditions are all deleted. In this embodiment, there is no duplicate data in the temporary storage table [interlocking condition] 430.

  In step 265, the screen hierarchy master table is referenced using the screen ID included in the link destination 432 of the link data 720 extracted in step 262 and stored in the temporary storage table [link condition] 430 as the search key. The hierarchy position is stored in the link destination hierarchy 431.

  In step 266, the value 411 (hierarchy 3) of the hierarchy position stored in the temporary storage table [hierarchy position] 410 is compared with the value 431 of the interlocking destination hierarchy stored in the temporary storage table [hierarchy position] 430. Only the linked data 710 at the hierarchy position with the smallest hierarchy difference is extracted from the temporary storage table [link condition] 430. Step 254 is repeated until the data (720, 730) in the temporary storage table [interlocking condition] 430 is exhausted. By providing a means of interacting with an authorized system administrator in step 254, It is possible to cover all linkages with higher layers that are affected by the linkage conditions changed by the system administrator. The system administrator can reduce the burden of investigating the influence on the upper hierarchy, and can ensure the reliability of the inspection item data of all hierarchies.

  If there is no data in the temporary storage table [interlocking condition] 430 in step 261, the process proceeds to step 267.

  In step 267, the server 10 extracts the inspection item data 322 from the inspection item master table using the interlocking condition change screen information and the interlocking destination 451 stored in the temporary storage table [interaction destination (2)] 450 as a search key. The inspection item correction screen 140 is displayed on the display device 21. The system administrator operates the inspection item correction screen 140 to change the information of the inspection item name 142 and the type / digit number 143 from the input device 22.

  In step 268, the server 10 receives from the management terminal 20 the inspection item name 142 and the type / digit number 143 changed to the contents of the inspection item correction screen 140.

  In step 269, the data received in step 268 is updated to inspection item data 321 in the inspection item master table shown in FIG.

  In step 270, data 451 of temporary storage table [link destination (2)] 450 is deleted.

  In step 271, in order to protect the past inspection result data, a result input area 360 is added to the inspection result table.

  In step 272, a program is automatically generated using a common template grouped into functional units based on the changed inspection items and interlocking conditions.

  In this example, the change of the inspection item has been described as an example. However, the addition and deletion of the inspection item, and the change of the existing existing flow structure or hierarchical structure can be executed by the same processing.

  Next, the procedure when the process proceeds to step 204 when the button operation information indicates “screen addition processing” in step 203 will be described.

  In step 204, the server 10 transmits the inspection work addition screen information and the data of the screen hierarchy master table to the management terminal 20, and causes the display device 21 to display the inspection work addition screen 110.

  In step 205, the server 10 receives from the management terminal 20 the data of the additional inspection screen name 111 and the additional position information 112 input to the content of the inspection work addition screen 110.

  In step 206, the server 10 shifts all the business screens in the hierarchy lower than the hierarchical position where the new business screen is stored from the additional position information 112 received in step 206 to the lower hierarchy. Also, a new screen ID is issued and the hierarchical position of the new business screen is determined.

  In step 207, based on the storage information processed in step 206, it is stored and updated in the screen hierarchy master table.

  In step 208, when the business screen hierarchy position 411 and the screen ID 412 added to the temporary storage table [hierarchy position] 410 are stored, the process proceeds to step 212, and the processing of the subsequent steps is executed.

  Next, the procedure when the process proceeds to step 225 when the button operation information indicates “screen deletion process” in step 203 will be described.

  In step 225, the server 10 transmits the inspection work deletion screen information and the data of the screen hierarchy master table to the management terminal 20, and causes the display device 21 to display the inspection work deletion screen 130.

  In step 226, the server 10 receives from the management terminal 20 the deletion / repair screen information 131 input in the content of the repair work deletion screen 130.

  In step 227, the server 10 shifts all the business screens in the lower hierarchy than the hierarchy position of the business screen to be deleted from the deletion inspection screen information received in step 227 to determine the hierarchical position.

  In step 228, the storage information determined in step 228 is stored and updated in the screen hierarchy master table.

  In step 229, the business screen layer position 411 and screen ID 412 added to the temporary storage table [layer position] 410 are stored.

  When all the inspection items on the deleted business screen are stored in the temporary storage table [inspection item] 420 in step 230, the process proceeds to step 251 and the processing of the subsequent steps is executed.

  As mentioned above, although embodiment of this invention was described concretely based on the embodiment, it is not limited to this and can be changed in the range which does not deviate from the summary.
