  As shown in FIG. 2, the display device external specification 6 input by the external specification input unit 11 includes a display device document 61, an input information specification 62, an inter-facility relation table 63, and an equipment screen specification 64. The The design information extracted from these document groups and stored in the equipment information DB 21 includes equipment symbol graphic information 211, equipment symbol change information 212, status display information 213, control response information 214, equipment related information 215, equipment symbols. The arrangement information 216 and the like.

  In the display device document 61, equipment symbols of each equipment type displayed on the display device screen (equipment type is a collection of equipment having the same specifications and the equipment symbols having the same display change). The figure pattern is displayed and how the figure pattern changes when data is received from the equipment. The display device document 61 is customer approval data. Here, in order to generate the equipment symbol graphic information 211 and the equipment symbol change information 212 stored in the equipment information DB 21, the all-point test apparatus 1 from a storage medium or the like. Shall be entered.

  In the input information specification 62, for each equipment symbol displayed on the display device screen, input data that triggers the display change of the equipment symbol is defined. There are two types of input data: status display information indicating the status of the equipment and control response information returned as a response to the control command for the equipment. . The input information specification 62 is customer presentation data. Here, in order to generate the status display information 213 stored in the facility information DB 21 and the control response information 214, the input information specification 62 is transferred from the storage medium to the all-point test apparatus 1. Shall be entered.

  The inter-facility relation table 63 defines other equipment whose equipment symbol is displayed and changed when the equipment symbol is changed in display by linking with the equipment for each equipment symbol displayed on the display device screen. Is done. The inter-facility relation table 63 is customer presentation data. Here, in order to generate the inter-facility relation information 215 stored in the equipment information DB 21, it is input to the all-point test apparatus 1 from a storage medium or the like. .

  In the equipment screen specification 64, it is defined where each equipment symbol displayed on the display device screen (equipment screen) is arranged and in what shape in the equipment screen. The equipment screen specification 64 is customer approval data. Here, in order to generate the equipment symbol arrangement information 216 stored in the equipment information DB 21, the equipment screen specification 64 is input to the all-point test apparatus 1 from a storage medium or the like. . Since similar internal data is generated in the display screen data 322 of the display device 3 based on the equipment screen specification 64, the internal data is referred to instead of inputting the equipment screen specification 64. It is good.

  The equipment symbol graphic information 211 is design information extracted from the display device document 61. As illustrated in the balloon, the equipment symbol graphic information is displayed on the display device screen by symbolizing the equipment for each type of equipment. It is determined. In this data example, two types of equipment graphic patterns of the traffic signal A and the track circuit B are defined. It should be noted that, for example, even with the same traffic signal, different equipment types and graphic patterns are assigned to each so that different specifications can be distinguished from each other.

  The equipment symbol change information 212 is design information extracted from the display device document 61. As illustrated in the balloon, the equipment symbol change information 212 is a graphic pattern display of equipment symbols when predetermined input data is received for each equipment type. It defines the content of the change. There are two types of input data, status display information and control response information, and the contents of display change for each input data are defined. In this data example, the change contents of the display color of the equipment symbol when the state change information corresponding to the two kinds of equipment of the traffic light A and the track circuit B are received are respectively defined. Here, for example, “line: white” represents a state in which the color of the line forming the equipment symbol graphic pattern (hereinafter referred to as “line color”) is “white”, for example, “surface: black”. Represents a state in which the color (hereinafter referred to as “surface color”) of a closed region (region surrounded by a line) included in the graphic pattern is “black”. Therefore, for traffic light A, the line color was “white” and the face color was “black” before the change (in the default state), but the line color after the change (when specific input data was received) It is specified that the face color changes to “blue” without changing with “white”.

  The state display information 213 is design information extracted from the input information specification 62, and as illustrated in the balloon, input data serving as an opportunity to display a graphic pattern of equipment symbols representing the state of each equipment. It prescribes. In this data example, the bit position of the input data of the status display information for the two equipments of the traffic signal A having the equipment name “A1” and the track circuit B having the equipment name “B1” is defined. The corresponding input data is “1 (1)” (the first bit of the first byte is “1” and all other bits are “0”), and the input data corresponding to the latter is “5 (6)” ( The sixth bit of the fifth byte is “1” and all other bits are “0”). In this example, the input data is defined by 1 bit. However, the input data may be defined by any combination of 2 bits or more, or multiple types of input data may be defined for the same equipment. Good. However, when a plurality of types of input data are defined for the same facility, it is necessary to define the facility symbol change information 212 in association with the type of each input data.

  The control response information 214 is design information extracted from the input information specification 62 and corresponds to a control response returned from the equipment to the display device 3 when a control command is transmitted to the equipment. It defines input data. Although a data example is not shown, the bit position of the input data of the control response information returned from each facility is defined similarly to the state display information 213.

  The inter-facility relation information 215 is design information extracted from the inter-facility relation table 63. As illustrated in the balloon, other related equipment whose equipment symbol display changes in conjunction with the equipment symbol of a certain equipment. It prescribes. In this data example, two types of equipment, track circuit B and track circuit C, which are linked to two traffic lights A whose equipment names are “A1” and “A2”, are defined as related equipment and linked to the former. The related equipment names are “B1”, “C3”, and “B5”, and the related equipment names that are linked to the latter are “B2”, “C4”, and “B6”.

  The facility symbol arrangement information 216 is design information extracted from the facility screen specification 64. As illustrated in the balloon, the display position of the facility symbol representing the state of each facility in the facility screen, the deformation parameter, It prescribes. The display position in the screen is defined by, for example, an X coordinate that represents a horizontal position of an upper left vertex of a rectangle that contains equipment symbols and a Y coordinate that represents a vertical position. In addition, the deformation parameter defines the deformation display method of the equipment symbol. For example, “double horizontal” means that a standard equipment symbol is enlarged and displayed twice in the horizontal direction (horizontal direction). Represent. In addition, changing the display color or displaying a blink can also be specified by the deformation parameter. In this data example, for the equipment symbols corresponding to the two equipments of the traffic signal A with the equipment name “A1” and the track circuit B with the equipment name “B1”, the former is a standard size coordinate (200, 40). It is specified that the former should be displayed at coordinates (170, 60) in a size doubled in the horizontal direction.

  FIG. 3 is an explanatory diagram of the operation of the test specification generation unit of the all-point test apparatus. Here, an operation in which the test specification generation unit 12 of the all-point test apparatus 1 reads out necessary information from the facility information DB 21 to generate the test specification 221 and stores it in the test specification DB 22 will be described.

  The test specification generation unit 12 first reads the equipment symbol change information 212, the state display information 213, the control response information 214, and the inter-facility related information 215 from the equipment information DB 21. Next, from all the records stored in the status display information 213 and the control response information 214, the equipment name displayed on the equipment screen (for example, a yard map of a certain station) to be subjected to the all-point test is used. Extract the corresponding records in order. The extraction order follows the registration order of each record in the order of the status display information 213 and the control response information 214, and a record associated with the contents of the extracted record is generated using the serial number indicating the extraction order as a test number. Then, it is additionally registered in the test specification 221. As a result, a record including the test number, the input data type corresponding to the test number (discrimination between status display information and control response information), and the input data allocation bit is additionally registered in the test specification 221. . In the data example shown in the balloon of FIG. 3, first, the record in the first line of the status display information 213 is extracted, the test number column is “1”, the input data type column is “status display information”, and the allocation bit column is “ The record in the first line “1 (1)” is additionally registered in the test specification 221.

  Next, the test specification generation unit 12 acquires the equipment type and equipment name from the extracted record, searches for a record of the inter-facility related information 215 that matches the equipment type and equipment name, and uses the related equipment from the record. Get the name. In the above data example, the equipment type “signal A” and the equipment name “A1” are acquired, the record in the first line of the inter-facility related information 215 is searched, and the related equipment names “B1, C3, B5” are acquired. Is done.

  Subsequently, the test specification generation unit 12 acquires the equipment type acquired from the extracted record and the related equipment name acquired from the inter-facility related information 215 by searching the equipment symbol arrangement information 216 (FIG. 2). A record corresponding to each of the equipment types is searched from the equipment symbol change information 212, and information before and after the change of the equipment symbol corresponding to each equipment name is acquired from the record. Then, information to be registered in the screen change content column of the test specification 221 is generated from the acquired information before and after the change of each equipment symbol, and is registered in the record of the test specification 221. In the above data example, the record corresponding to the traffic signal A having the equipment name “A1”, the track circuit B having the equipment name “B1”, and the track circuit C having the equipment name “C3” is the equipment symbol change information 212. The surface color of the equipment symbol corresponding to the equipment name “A1” is changed from “black” to “blue”, and the line color of the equipment symbol corresponding to the equipment name “B1” is changed from “white” to “green”. “A1: surface (black → blue), B1: line (white → green),...”, Which indicates a change or the like, is registered in the screen change content column of the test specification 221.

  Similarly, test numbers are assigned sequentially to the input data for the equipment displayed on the equipment screen subject to the all-point test, and the contents of the screen change when the input data shown in the assigned bit field are entered are displayed on the screen. Records described in the change content column are registered in the test specification 221. Each record registered in the test specification 221 by the above processing corresponds to one test item, and input data defined by the data in the input data type field and the assigned bit field is input to the display device 3. It defines a test specification for confirming whether or not the change content of the display device screen matches the description content of the screen change content column.

  FIG. 4 is an explanatory diagram of the operation of the simulated input information generation unit of the all-point test apparatus. Here, an operation in which the simulated input information generation unit 131 of the all-point test apparatus 1 reads out necessary information from the test specification DB 22 to generate simulated input information 231 and stores it in the simulated input information DB 23 will be described.

  The simulated input information generation unit 131 reads the test specification 221 from the test specification DB 22, and generates simulated input information 231 by copying the data in three columns of the test number column, the input data type column, and the assigned bit column. And stored in the simulated input information DB 23.

  FIG. 5 is an explanatory diagram of the screen storage operation in the all-point test execution unit of the all-point test apparatus. Here, the all-point test execution unit 13 and the screen storage unit 132 of the all-point test apparatus 1 read the simulated input information 231 from the simulated input information DB 23, execute the all-point test, and store the image data of the execution result screen. An operation of storing the screen data 241 in the saved screen DB 24 will be described.

  The all-point test execution unit 13 receives an operation for selecting a target screen for the all-point test (not shown), and then first obtains screen data (initial screen) of the initial state of the equipment screen to be subjected to the all-point test from the display device 3. get. The acquired screen data is registered in the storage screen data 241 by the screen storage unit 132. At this time, as illustrated in the balloon of FIG. 5, for example, the storage screen data body of the initial screen is stored in a certain data block, and link information to the data block is set to the test number of the storage screen data 241 of “0”. ”In the record.

  Next, the all-point test execution unit 13 reads the simulated input information 231 corresponding to the equipment screen from the simulated input information DB 23, and sequentially applies the corresponding simulated input from the first record (record whose test number column is “1”). Data is generated and transmitted to the display device 3 one by one. The display device 3 is set in advance to operate in the all-point test mode. The simulated input data received by the display control unit 31 is transferred to the display program 321 and updated by the display program 321. (Test result screen) is returned to the all-point test execution unit 13. The all-point test execution unit 13 delivers the test result screen data transmitted from the display device 3 to the screen storage unit 132 together with the corresponding test number. The screen storage unit 132 additionally registers the transferred test result screen data in the storage screen data 241 in association with the designated test number. After completing the series of processes, the all-point test execution unit 13 transmits the next simulated input data to the display device 3 and repeats the same process. As a result, the test screen data for all input data related to the equipment screen is finally registered and stored in the storage screen data 241.

  FIG. 6 is an explanatory diagram of a test result determination operation in the all-point test execution unit of the all-point test apparatus. Here, the all-point test execution unit 13, the difference extraction unit 133, and the symbol change determination unit 134 of the all-point test apparatus 1 read the save screen data 241 from the save screen DB 24, and each test result screen and initial screen The operation of determining whether or not it matches the screen change contents of the test specification 221 read from the test specification DB 22 after extracting the difference and storing the determination result in the test result DB 25 as the test result 251 will be described.

  When the test result screen data for all the input data related to the target screen of the all-point test is stored in the storage screen DB 24, the all-point test execution unit 13 reads the storage screen data 241 from the storage screen DB 24, and sets each test number. Data of each test result screen is acquired and compared with the initial screen to determine whether or not the content of the display change matches the screen change content described in the test specification 221. As a result, if the content of the display change matches the content of the screen change described in the test specification 221, a record including the test number and the determination result “OK” is additionally registered in the test result 251, and the content of the display change Is not consistent with the screen change content described in the test specification 221, a record including the test number, the determination result “NG”, and detailed data related to the determination result is additionally registered in the test result 251, and the test result DB 25 To store. In this determination, the difference extraction unit 133 generates difference screen data that is bitmap data that represents, in binary, a portion that is different in display between each test result screen and the initial screen. By erasing the difference screen data, it is possible to detect whether or not there is a display change other than the expected display change on the test result screen.

  FIG. 7 is an explanatory diagram of the operation of the difference extraction unit of the all-point test apparatus. Here, an operation in which the difference extraction unit 133 of the all-point test apparatus 1 generates binary difference screen data from a certain test result screen and an initial screen will be described.

  As illustrated in FIG. 7, the difference extraction unit 133 uses binary data of “0” for pixels whose display colors match between the initial screen and the test result screen, and “1” for pixels with different display colors. Binary difference screen data is generated by generating bitmap data consisting of In the data example of FIG. 7, the upper left initial screen and the upper right test result screen are the color of the upper traffic light symbol and the color of the upper part of the track circuit symbols (shown in bold for convenience). Since the other parts are the same display, the pixels of part of the traffic light symbol (black circle part) and part of the track circuit symbol figure (thick line part) with different display colors are displayed. Binary difference screen data, which is “1” and others are “0”, is generated.

  FIG. 8 is an example of the display change contents of the equipment symbol and the difference screen data. Assuming that the column before change is a display image of the equipment symbol on the initial screen and the column after change is a corresponding display image on the test result screen, the difference screen data includes binary bits as shown in the difference column. Map data is generated. In FIG. 8, the hatched portion is a display color other than white or black for convenience.

  FIG. 9 is an explanatory diagram of the operation of the symbol change determination unit of the all-point test apparatus. Here, an operation will be described in which the symbol change determination unit 134 of the all-point test apparatus 1 determines whether a change from an initial screen of a certain test result screen matches an intended screen change content for a corresponding test item. To do.

  For each test item identified by the test number, the symbol change determination unit 134 determines whether the test result screen stored in the storage screen DB 24 matches the intended screen change content described in the test specification 221. It is determined using the difference screen data.

  As illustrated in FIG. 9, from the test result screen for the test item of the record whose test number is “1” registered in the test specification 221, the difference screen data before determination such as the lower left is the difference extraction unit 133. Is generated by

  At this time, the symbol change determination unit 134 first reads the data of the intended screen change content from the screen change content column of the record with the test number “1” from the test specification 221 so that the equipment name is “A1”. The color of the equipment symbol “” changes from “black” to “blue”, and the line color of the equipment symbol whose equipment name is “B1” should change from “white” to “green”.

  Next, the symbol change determination unit 134 searches the equipment symbol arrangement information 216 for records having the equipment names, and uses the equipment type field, the X coordinate field, the Y coordinate field, and the deformation parameter field data of the record. By reading, the equipment type of the equipment symbol whose equipment name is “A1” is “Signal A”, the coordinates of the display position are (200, 40), the standard size is displayed, and the equipment name is “B1” The equipment type of the equipment symbol is “track circuit B”, the coordinates of its display position are (170, 60), and it is grasped that it should be displayed in a size doubled in the horizontal direction. .

  Subsequently, the symbol change determination unit 134 searches the equipment symbol graphic information 211 for records having those equipment types, and reads the data in the graphic pattern field and the standard size field of the record, thereby causing the traffic signal A and the track circuit. Obtain the graphic pattern and standard size of equipment symbols such as B.

  Based on the information acquired and acquired for each equipment name, the symbol change determination unit 134 then changes the image data before the change and the change for each equipment symbol whose display should change between the initial screen and the test result screen. For example, corresponding to the traffic light A1, the graphic pattern of the traffic light A whose surface color before change is “black” and the traffic light A whose surface color after change is “blue” are generated. Two image data of a graphic pattern are generated.

  Subsequently, the symbol change determination unit 134 generates the generated two pieces of image data, and the image data of the coordinates of the display position of the equipment symbol on the actual initial screen and the test result screen stored in the storage screen data 241. By comparing each of them, it is determined whether or not both are displayed correctly. If the display is correct, the difference screen data corresponding to the rectangular area where the corresponding equipment symbol is displayed is deleted. Thereby, if the display change of the equipment symbol corresponding to the traffic light A1 is correct, as illustrated in FIG. 9, the difference image data of the corresponding rectangular area a1 is deleted from the difference screen before the determination, and the difference screen after the determination It becomes like this.

  By performing the above processing for each equipment symbol whose display should be changed between the initial screen and the test result screen, the symbol change determination unit 134 sequentially corresponds to the rectangular areas a1, b1, and so on from the difference screen before the determination. The difference screen data of c3 and b5 are erased. And if all the difference screen data is deleted like the difference screen after the determination illustrated in FIG. 9 in the end, it can be understood that there is no other portion where the display is changed. Is determined to be normal (OK), and if any part of the difference screen data remains, it can be seen that there is another part of the display change, so the symbol change on the test result screen is abnormal ( NG).

  FIG. 10 is an explanatory diagram of the operation of the test result output unit of the all-point test apparatus. Here, the test result output unit 14 of the all-point test apparatus 1 outputs the all-point test result 7 from the test specification 221 read from the test specification DB 22 and the test result 251 read from the test result DB 25. Will be described.

  When the test result 251 is stored in the test result DB 25, the test result output unit 14 uses the creation date and time of the test result 251 as the test date and the header information describing the name of the selected test target screen, and each subsequent test An all-point test result 7 consisting of a list of the test content of the number and the test determination result is output to a printer, a display or the like.

  Of the output data of the all-point test result 7 exemplified in the balloon of FIG. 10, the simulated input information and the data of the screen change contents are the input data type column acquired from the corresponding record of the test specification 221 (FIG. 3), the allocation It is generated by editing each data in the bit column and the screen change content column. The determination result and detailed data are generated by acquiring the determination result column and the detail column data from the corresponding record of the test result 251 (FIG. 6).

  FIG. 11 is a flowchart showing an overall flow of the all-point test method according to the present invention. Hereinafter, the flow of processing in this all-point test method will be described with reference to this flowchart.

  First, in step S1, the all-point test device 1 (external specification input unit 11) inputs the external specification of the display device, extracts various design information necessary for the all-point test, and stores it in the facility information DB 21. (See FIG. 2). Next, in step S2, the all-point test apparatus 1 (test specification generation unit 12) reads the equipment information DB 21, creates a test specification 221 and stores it in the test specification DB 22 (see FIG. 3). Next, in step S3, the all-point test apparatus 1 (simulated input information generating unit 131) reads the test specification DB 22 to generate the simulated input information 231 necessary for performing the all-point test, and the simulated input information DB 23 (See FIG. 4). Next, in step S4, the all-point test apparatus 1 (all-point test execution unit 13) stores the initial screen of the all-point test target screen in the storage screen DB 24. Next, in step S5, the all-point test apparatus 1 (all-point test execution unit 13) executes the all-point test according to the test specification 221 and stores the test result screen for each test number in the storage screen DB 24. (See FIG. 5).

  Subsequently, the all-point test apparatus 1 (all-point test execution unit 13) determines whether the test result for each test number is normal (OK) or abnormal (NG) in step S6 and thereafter, and finally in step S12 The point test result 7 is output and the process is terminated (see FIG. 10).

  In determining the test result, the all-point test apparatus 1 (all-point test execution unit 13) first sets the test number to 1 in step S6, and the test result for the test number in steps S7 to S9. If all the determinations are not completed (“No” in step S10), the next test number is updated in step S11, the process returns to step S7, and the same determination process is repeated. If all the determinations are completed (“Yes” in step S10), the process proceeds to step S12.

  In determining the test results for the individual test numbers, the all-point test apparatus 1 (difference extraction unit 133) first initializes the target screen for all-point tests stored in the storage screen DB 24 in step S7. The difference between the screen and the test result screen (binary difference screen data) is extracted (see FIG. 7). Next, in step S8, it is determined whether or not the change contents of the equipment symbol match the screen change contents described in the test specification 221. In step S9, the determination result is registered in the test result DB 25. (See FIG. 6).

  FIG. 12 is a detailed flowchart of the process for determining the suitability of the symbol change content in step S8 of FIG. This process is executed by the symbol change determination unit 134 (see FIG. 9).

  First, in step S81, the expected screen change content for each equipment symbol is obtained from the record corresponding to the test number in the test specification 221. Next, in step S82, it is determined whether or not determination has been completed for all equipment symbols whose display changes. If all determinations have not been completed ("No" in step S82), the process proceeds to step S83. If all the determinations are completed (“Yes” in step S82), the process proceeds to step S87.

  In step S83, the equipment symbol coordinates of the equipment for which the validity of the display change is undetermined, that is, the coordinates of the display position of the equipment symbol are acquired, and in the subsequent step S84, both the initial screen and the test result screen By comparing the image data displayed in the coordinates with each other, the validity of the display change of the equipment symbol is determined. If the determination result is appropriate (“Yes” in step S85), in step S86, After deleting the difference data of the corresponding portion from the previously extracted difference screen, the process returns to step S82 and the same process is repeated. On the other hand, if the determination result is not valid (“No” in step S85), the determination result is set to NG in step S88, and the process ends.

  In step S87, it is determined whether or not there is difference data on the difference screen. If there is no difference data (“Yes” in step S87), the determination result is set to OK in step S89 and the process ends. . On the other hand, if there is difference data (“No” in step S87), the determination result is set to NG in step S88, and the process ends.

  As described above, according to the all-point test method according to the present invention, the external specifications of the display device are input to the all-point test apparatus 1 using a storage medium (for example, CD-ROM, DVD, portable memory, etc.). By selecting the target screen for all-point test and instructing the start of the test, the all-point test on the display device screen is automatically executed, and the validity of the screen change for the input data from each facility is automatically performed. The result of the all-point test is output. Therefore, it is possible to easily execute the all-point test on the display device screen without using a field equipment simulator or preparing a correct image.

  Although the description of the mode for carrying out the present invention has been described above, the mode of the present invention is not limited to the above mode, and various modifications can be made without departing from the gist of the present invention. Is possible. Moreover, although the form which made the display apparatus for operation management systems an example was demonstrated, the application object of this invention is not limited to an operation management system, The display of the various symbol figures arrange | positioned on a screen is from the outside. The present invention can also be applied to various systems including a display device that changes depending on data reception or operation.
