It is necessary to visually check the situation where the problem occurred and important points. A capture control command for saving a captured image is added to the command command list for details (see details below with reference to “command command list”, “command command log” and flowcharts below).

・ Feature 4
It has a function for controlling the power supply of the display device 150. Thereby, it is possible to cope with a test item to be operated for the first time after turning on the power (for example, display of the initial appearance of the gaming machine when the power is turned on). In pursuit of reproducibility, it is possible to automatically test from power-on. An instruction for controlling the power is added to the instruction command list and processed via the instruction command transmission program. (Details will be described later with reference to the “command command list” and flowcharts below).

・ Feature 5
The feedback information generation and the mail delivery system are linked. The operation is performed according to the setting of the feedback information table (details will be described later with reference to the “feedback information table” and each flowchart below).

  First, with reference to FIG. 5, an overview of the functions of the modules constituting the display device test software 500 will be described.

  When the display device test software 500 is activated and the display device test system 100 is activated, the overall program module 502 downloads the command command list 520 and the feedback information table 524 from the file server 373 and activates each submodule. Each submodule is terminated when the system is terminated.

  The feedback information processing program module 516 instructs each sub-module to execute processing corresponding to the feedback information sent from the display device 150 (regardless of error or non-error). The processing corresponding to the feedback information is described in advance in the feedback information table 524 (described later with reference to FIGS. 6 and 7). The feedback information table is prepared for each type of test (aging test, automatic test, manual test) for display device software (project), and is stored in the file server 520 in advance. That is, a feedback information table of “multiple files per project” × “the number of projects” is prepared in advance.

  FIGS. 6A, 6B, 7A, and 7B are views illustrating feedback information tables. FIG. 6A is a diagram illustrating a feedback information table for the type “aging test” of the project name “display device A”. FIG. 6B illustrates a feedback information table for the type “aging test” of the project name “display device B”. FIG. 7A illustrates a feedback information table for the type “automatic test” of the project name “display device A”. FIG. 7B illustrates a feedback information table for the type “manual test” of the project name “display device A”. For example, in FIG. 6A, the left end of the table indicates a feedback information number. As an example, the number “2” indicates the feedback information of the “CPU zero division” error as shown in the “feedback information type name” in the table. As processing corresponding to the feedback information of each row of the table, each column of the table “reset at occurrence”, “moving image capture”... “Reset on occurrence” means that if feedback information registered in the table as “Yes” is sent, the display device 150 is reset (restarted) after sending the feedback information. This means that the display device 150 that has sent the feedback information registered in the table with “Reset when occurrence” is “Yes” resets after the feedback information). As described above, the “reset upon occurrence” setting in the feedback information table is matched in advance according to whether or not the display device 150 that sent the feedback information is reset. The processing of each column of the feedback information table will be described in detail in the description with reference to each flowchart described later, including “reset at occurrence” and others.

  Referring to FIG. 5 again, the command command transmission program module 518 performs manual and automatic operations based on the command command list 520. The command command sent from the command command transmission program module 518 to the display device 150 is recorded in the command command log file 510. Further, the command command transmission program module 518 performs a reproduction operation based on the reproduction command log file 508. The reproduction command log file 508 will be described in detail in the description with reference to the flowchart described later.

  FIG. 8 is a diagram illustrating an instruction command list 520. As list information, (0) in the figure is the project name (for example, display device A), and (1) is the software version number of the project name. In the figure, (2) is a group number, and the command commands defined in the command command list are defined by being divided into groups. For example, as shown in FIG. 8, “(1) Group (normal fluctuation 103 after power-on, normal change 103)” indicates the normal fluctuation 103 of the display symbol for the gaming machine of the display device 150, and “(2) Group (after power-on). 1 or more groups are defined in order such that the normal variation 203 of the display symbols for gaming machines is indicated by “Normal variation 203)”.

  (4) in FIG. 8 is a command to be sent, and commands in each row are sequentially transmitted from the top. Commands obtained by removing (3) and (5) from (4) are command commands to be sent to the display device 150. (3) is a power control command that instructs the power control program module 526 to turn off the power with "1000: POWER_OFF" and to turn on the power with "4000: POWER_ON". The first 4000 of “4000: POWER_ON” is an offset time from the transmission of the command “1000: POWER_OFF”, and its unit is msec. In the following, similarly, the number at the beginning of the following command is the offset time from the previous command transmission, and the unit is msec. However, the first 1000 in the first command command “1000: POWER_OFF” in FIG. 8 is the time from the start of command command transmission log, and the unit is msec. (5) is a capture control command for instructing start and end of moving image capture (CAPTURE_START and CAPTURE_STOP, respectively). A capture moving image file name is optionally given to the capture control command CAPTURE_STOP.

  FIG. 9 is a diagram illustrating an instruction command log file 510. In the figure, (0) to (5) are log information corresponding to (0) to (5) in the instruction command list shown in FIG. Here, (5) is an example in which the captured moving image file name created by the capture control command CAPTURE_STOP in the command command list shown in FIG. 8 is output. (6) is the start date and time of the log. (7) is feedback information from the display device 150 and is recorded by the command command transmission program module 518.

  Referring to FIG. 5 again, the mail transmission program module 514 transmits mail to the designated address to the mail server 375 in response to an instruction from the feedback information processing program module 516. The mail transmission program module 514 basically follows the function of a well-known mailer, and further transmits an edited mail based on a standard sentence prepared in advance in this embodiment. When no destination is set, the mail transmission program module 514 does not transmit mail.

  As described above, the mail server 375 manages a mailing list for each project, and when a mail addressed to a specific project is received from the PC 110, a copy of the received mail is sent to all mail users registered in the mailing list of the project. Broadcast. Thereby, in the case of an automatic check of the display device 150, it is used for confirmation at the destination, such as an error notification on a holiday. Further, by sending information to the mobile mail function or the like, the operator can immediately cope with the trouble that has occurred. Furthermore, even if the person in charge of the test does not go to the company, the operation status can be confirmed through the Internet.

  The backup program module 506 receives a bug information sheet (described later), a reproduction command log file 508 (or an instruction command log file 510), and a capture at the time of feedback as a result of a reproduction test in response to an instruction from the feedback information processing program module 516. The bug information file including the moving image file 511 and the like is transmitted to the file server 373, and the bug information is backed up.

  The moving image capture program module 512 starts and ends the capture of moving image data in response to an instruction from the command command transmission program module 518. That is, the moving image data that is the imaging result information of the capture device 160 that is always operating during the test is captured during the period from the start to the end of the moving image capture by the capture control command instructed from the command command transmission program module 518. The file 509 is stored in the HDD 341 (storage for one shot). The moving image capture program module 512 repeats saving for several new shots as long as the capacity of the HDD 341 allows. Similarly to the known video capture application, the video capture program module 512 has various settings for capturing moving image data, that is, frame rate, resolution, loop time (capture time in the ring buffer, for example, 1 min), captured video. An image file name or the like can be set.

  The power control program module 526 turns on / off the power switch 105 according to the power control command instructed from the command command transmission program module 518.

(Program processing explanation)
Processing related to the above-described operation of the display device test system of the present embodiment is performed according to the processing procedure shown in the flowcharts of FIGS. FIG. 10 shows the display device control contents executed by the CPU 403, which is performed by the CPU 403 reading and executing a display device control program stored in the ROM 404. FIGS. 11 to 18 show the display device test system control contents executed by the processor 320. The processor 320 loads the display device test software 500 stored in the HDD 341 into the RAM 332 and executes it. FIG. 19 shows the contents of file management processing executed by the processor of the file server 373. The processor of the file server 373 loads the file management program 528 stored in the HDD (not shown) into the RAM (not shown). It is done by executing.

  First, with reference to FIG. 10A, display control processing among the display device control contents executed by the CPU 403 will be described. It should be noted that a desired display instruction (command command) is transmitted from the PC 110 to the CPU 403 of the display device 150 and the CPU 403 displays a desired moving image on the variable display device according to the command command. / F and the control method of the CPU 403 itself (image processing, symbol variation time management, etc.) can be the same as when a conventional display device having a variable display device applied to a gaming machine is used. In the embodiment, only components related to the present invention and supplemental parts thereof will be described.

  In FIG. 10A, the CPU 403 performs initial setting processing of the CPU 403 after the power is turned on (step S1000), and displays the result of command command input detection from the PC 110 monitored by interrupt processing (not shown). Determination is made (step S1010). If there is no new command input, the process proceeds to step S1040 without doing anything.

  When a new instruction command is input, the input new instruction command is set in the set area on the RAM 405 (step S1020), data unique to the input instruction command is set in the RAM 405 (step S1030), and the process proceeds to step S1040. move on.

  Next, the CPU 403 performs image data set processing (step S1040). Specifically, the VDP control data in the program ROM 404 is written to the VDP output buffer on the RAM 405 based on the data unique to the input command set in the RAM 405. If the information in the VDP output buffer may be output to the VDP, the output permission flag is turned ON.

  The CPU 403 determines an output permission flag (step S1050), and if it is OFF, the process returns to step S1010.

  When the output permission flag is ON, the CPU 403 maps and writes the information of the VDP output buffer to the data register of the VDP 406 in the address space of the CPU 403, writes the address bus, the data bus, the write enable, the chip By issuing an instruction to the VDP 406 by selection, image data such as sprite / scroll read from the character ROM 407 is developed on the video RAM 408. Then, VDP data output processing is performed to instruct the VDP 406 to display the image data on the video RAM 408 in the display area window of the variable display device 409 (step S1060), and the process returns to step S1010.

  Next, feedback information transmission processing among the display device control contents executed by the CPU 403 will be described with reference to FIG. The process of FIG. 10B is a process for transmitting feedback information such as a parameter exception, a process failure, a checksum error, etc. in the process of the program of FIG. The software developer embeds the feedback information transmission process of FIG. 10B as a check code in advance at an appropriate location where the feedback information in the processing of the program of FIG. For example, in the processing of the program shown in FIG. 10A, in the illegal processing route when the processing failure occurs, the feedback information transmission shown in FIG. 10B in which “processing failure” is set as an argument of the routine. Embed the process.

  In FIG. 10B, the CPU 403 sets the feedback information number corresponding to the number in the feedback information table of FIGS. 6 and 7 corresponding to the argument in step S1080 in the feedback information. For example, in the test of the software of the display device 150 (project name “display device A”), when the argument is “processing failure”, the CPU 403 provides feedback in FIGS. 6A, 7A, and 7B. The feedback information number “7” of “processing failure” defined in common in the information table is set in the feedback information. In step S1090, the CPU 403 transmits feedback information to the PC 110.

FIG. 11 is a flowchart showing the processing procedure of the overall program module 502.
As in the case of starting a general application, for example, when the icon of the display device test software 500 displayed on the screen of the monitor 120 is selected by the operation of the mouse 140 of the operator, the processor 320 displays via the OS. The device test software 500 is activated. When the display device test software 500 is activated, the processor 320 first activates the overall program module 502.

  In FIG. 11, the processor 320 displays a startup selection screen 2001 as shown in FIG. 20 on the monitor 120 (step S1100). When the operator inputs a project name (for example, display device A) on the startup selection screen and checks the selection of the test type (aging test, automatic test, manual test) (for example, aging), the processor 320 The name and type information is acquired and saved in the RAM 332 (step S1102).

  When the START button is selected by the operator on the startup selection screen of FIG. 20 (step S1104), the processor 320 transmits an instruction command list request in which the project name is set as an option to the file server 373. One or more command command list files (extension is .lst) corresponding to the project name are downloaded (step S1106). For example, a command command list 520 for the display device A as shown in FIG. 8 is downloaded.

  Next, the processor 320 displays the file list of the instruction command list downloaded from the file server 373 on the startup selection screen 2001 in FIG. 20 (reference numeral 2010 in FIG. 20), and selects a desired instruction from the file list 2010 in the instruction command list. The command command list file list 2010 is activated so that the command list can be selected. When a desired instruction command list (for example, zzz.lst) is selected from the instruction command list file list 2010 by the operator's operation of the mouse 140, the processor 320 makes the instruction command list file list 2010 inactive ( If the display turns gray), the process proceeds to step S1108.

  Further, the processor 320 transmits a feedback information table request in which the project name and type are set as options to the file server 373, and downloads a feedback information table file corresponding to the project name and type from the file server 373 (step S1107). ). For example, the feedback information table 524 for the aging test of the display device A as shown in FIG.

  Next, the processor 320 activates each submodule of the submodule group 504 by multitasking (step S1108), and determines whether or not the type is a manual test (step S1109).

  If it is not a manual test, the processor 320 sends an instruction command list execution instruction to the instruction command transmission program module 518 (step S1122), and the status on the select screen at startup in FIG. A message indicating that the test is in progress is displayed (step S1124). When the processor 320 receives the test end notification from the command command transmission program module 518 (step S1126), the processor 320 displays the test status related to the type, for example, the end of the aging test, in the status on the startup selection screen of FIG. (Step S1128), the process proceeds to step S1121.

  On the other hand, in the case of a manual test, the processor 320 displays a list of group names in the selected command command list on the startup selection screen 2001 in FIG. 20 (reference numeral 2030 in FIG. 20), and a list of group names 2030. The group name list 2030 is activated so that a desired group name can be selected from the list. When a desired command command list (for example, Group z) is selected from the group name list 2030 by operating the mouse 140 of the operator, the processor 320 makes the group name list 2030 inactive (display is grayed out). Etc.), and the process proceeds to step S1110.

  In step S1110, the processor 320 transmits an instruction command list execution instruction in which the group number of the selected group name in the selected instruction command list is set as an option to the instruction command transmission program module 518 (step S1110). For example, one group selected from the group numbers “(1) Group (normal variation 103 after power-on, normal variation 103)”, “(2) Group (normal variation 203 after power-on, etc.)” in the command command list 520 of FIG. The group number is set as an option. Next, the processor 320 displays a test status related to the type, that is, that a manual test is being performed, in the status on the startup selection screen of FIG. 20 (step S1112). When the processor 320 receives the test end notification from the command command transmission program module 518 (step S1114), the processor 320 advances the process to step S1150.

  In step S1150, the processor 320 displays the “Manual OK” and “Manual NG” buttons on the startup selection screen 2001 in FIG. 20 (reference numerals 2020 and 2022 in FIG. 20, respectively), and “Manual OK” and “Manual NG” Each button of “Manual NG” is activated to be selectable. If the test is successful and the “Manual OK” button is selected by operating the operator's mouse 140, or if the test fails and the “Manual NG” button is selected by operating the operator's mouse 140, the processor 320 , “Manual OK” and “Manual NG” buttons are made inactive (display becomes gray, etc.), and the process proceeds to step S1153.

  In step S1153, if the processor 320 determines that the “manual OK” button is selected, the process proceeds to step S1115. If the processor 320 determines that the “manual NG” button is selected, the process proceeds to step S1157.

  In step S1157, as an exception process, the processor 320 transmits feedback information from the overall program module 502 inside the display device test software 500, which is not feedback information from the display device 150. Specifically, the processor 320 sets the feedback information number “11” of “TESTER ERROR” defined in common in the feedback information tables of FIGS. 6A, 7 </ b> A, and 7 </ b> B as feedback information. The feedback information is transmitted to the feedback information processing program module 516.

  Then, the processor 320 determines whether or not there is a non-executed next group in the instruction command list (step S1115).

  When there is no unexecuted next group, the processor 320 displays the test status related to the type, that is, the end of the manual test in the status on the startup selection screen of FIG. 20 (step S1120), and the process is step S1121. Proceed to

  If there is an unexecuted next group in step S1115, the processor 320 displays the test status related to the type, that is, the end of manual test 1 group in the status on the startup selection screen of FIG. S1116), the process proceeds to step S1118. When the operator selects the manual group START button on the startup selection screen of FIG. 20 (step S1118), the processor 320 returns the process to step S1140.

  In step S1121, the processor 320 monitors an input event. Here, when the operator selects the Refresh button on the startup selection screen of FIG. 20, the processor 320 returns the process to step S1100. On the other hand, in step S1121, when the operator selects the end button (the x button on the upper right of the screen) on the startup selection screen in FIG. The test software 500 is terminated (step S1122).

  FIG. 12 is a flowchart showing the processing procedure of the command command transmission program module 518. The processor 320 determines the state in step S1200, and monitors the instruction command list execution instruction from the overall program module 502 when not testing (step S1202).

  Upon receiving the instruction command list execution instruction, the processor 320 causes the state to transition to testing in step S1204. Then, the processor 320 generates an instruction command log file having the name of the downloaded instruction command list with the extension .lst as .log, and obtains the same project name, version number, and OS from the instruction command list. The time stamp (log start date and time) edited based on the date and time information is recorded in the command command log file (step S1205). For example, the command command log file 510 of FIG. 9 is generated, and log information (0), (1), and (6) in FIG. 9 is recorded therein.

  In step S1260, the processor 320 takes the transmission timing of the unexecuted command to be executed next in the instruction command list. This processing is performed by using the number at the beginning of the command shown in FIGS. 8 and 9 (offset time from the previous command transmission) as the transmission timing interval of the current command from the previous command. Transmission timing is taken.

  In step S1206, the processor 320 determines whether or not the group number of one group is set as an option in the instruction command list execution instruction (that is, manual test). If it is not a manual test, the processor 320 analyzes an unexecuted command to be executed next in the instruction command list in step S1210. In the case of the manual test, in step S1208, the processor 320 analyzes an unexecuted command to be executed next in the designated group in the instruction command list of the group number set as an option in the instruction command list execution instruction.

  Next, the processor 320 branches the process according to the analyzed command (step S1212). If the unexecuted command to be executed is an instruction command, the processor 320 transmits the instruction command to the display device 150 (step S1214), and the process proceeds to step S1221. If the unexecuted command to be executed is a capture control command, the processor 320 advances the process to step S1216. If the capture control command is CAPTURE_STOP instead of CAPTURE_START, the capture moving image file name (extension is .movie) is defined. . Then, in step S1218, as described above with reference to FIG. 8, the processor 320 sets the captured video file name as an option when the capture control command is CAPTURE_START, or as an option when the capture control command is CAPTURE_STOP. The capture control command is transmitted to the moving image capture program module 512, and the process proceeds to step S1221. If the unexecuted command to be executed is a power control command, the processor 320 transmits the power control command (POWER_OFF or POWER_ON) to the power control program module 526 as described above with reference to FIG. 8 (step S1220). The process proceeds to step S1221.

  In step S1221, the processor 320 adds the executed command to the instruction command log file. For example, as shown in FIG. 9, one line (4) in FIG. 9 is added to the command command log file 510. However, if the executed command is the capture control command CAPTURE_STOP, the above-described captured moving image file name is added to the command command log file (for example, (5) in FIG. 9 described above).

  Next, the processor 320 determines whether there is an unexecuted next command in the instruction command list (step S1222), and if there is an unexecuted next command, the process returns to step S1200. If there is no unexecuted next command, the processor 320 transmits a test end notification to the overall program module 502 (step S1224), transitions the state to non-test in step S1226, and returns the process to step S1200.

  If it is determined in step S1200 that the state is being tested, the processor 320 determines whether or not the state has received an input event during the test (step S1228). If the input event is received during the test, the processor 320 determines the event. (Step S1232). When the input event is feedback information from the feedback information processing program module 516, the processor 320 refers to the feedback information number set in the feedback information, and records the feedback information in the instruction command log file. (Step S1238). For example, when the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A has been downloaded, the processor 320 sets the feedback information number “0” set in the feedback information. ”Is recognized, and the log information (BOOT) of (7) in FIG. 9 is recorded in the command command log file 510 of FIG. 9. Then, the processor 320 returns the process to step S1200.

  When the input event in step S1232 is a test stop instruction from the feedback information processing program module 516, the processor 320 transitions the state to the test stop (step S1234). Then, the processor 320 returns the process to step S1200.

  If the input event in step S1232 is a level N reproduction setting instruction from the feedback information processing program module 516, the processor 320 transitions the state to a reproduction test (step S1240). Next, in step S1242, the processor 320 analyzes an unexecuted command to be executed next in the level N reproduction command log file 508 corresponding to the level N reproduction setting instruction.

  Next, the processor 320 branches the process according to the analyzed command (step S1244). If the unexecuted command to be executed is an instruction command, the processor 320 transmits the instruction command to the display device 150 (step S1246), and the process proceeds to step S1250. If the unexecuted command to be executed is a power control command, the processor 320 transmits the power control command (POWER_OFF or POWER_ON) to the power control program module 526 as described above with reference to FIG. 8 (step S1248). The process proceeds to step S1250.

  In step S1250, the processor 320 determines whether or not there is an unexecuted next command in the level N reproduction command log file 508, and if there is an unexecuted next command, the process returns to step S1200. If there is no unexecuted next command, the processor 320 transmits a reproduction test end notification to the feedback information processing program module 516 (step S1252), causes the state to transition to test stop in step S1254, and the process to step S1200. return.

  If the input event in step S1232 is a test restart instruction from the feedback information processing program module 516, the processor 320 transitions the state to testing (step S1236). Then, the processor 320 returns the process to step S1200.

  If the processor 320 determines in step S1200 that the state is a test stop, the processor 320 waits for a state transition.

  If it is determined in step S1200 that the state is being tested, the processor 320 determines whether or not the state has received an input event during the test (step S1228). If the input event has not been received during the test, the processor 320 performs processing. The process proceeds to S1206 (steps S1228 → S1256 → S1260). On the other hand, when the processor 320 determines in step S1200 that the state is in the reproduction test, the processor 320 advances the process to step S1242 (step S1200 → S1228 → S1256 → S1242).

  FIG. 13 is a flowchart showing the processing procedure of the feedback information processing program module 516. The processor 320 monitors feedback information from the display device 150 (step S1300). When the feedback information is received in step S1300, the processor 320 sends the feedback information to the command command transmission program module 518 (step S1301). Next, the processor 320 sends a test stop instruction to the instruction command transmission program module 518 (step S1302).

  Then, the processor 320 refers to the feedback information table to determine whether the “reset at occurrence” corresponding to the feedback information is “Yes”, that is, whether the display device 150 is reset after transmitting the feedback information. (Step S1303). For example, when the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A has been downloaded and the feedback information is BOOT (feedback information number “0”), the processor 320 Refers to the column ““ Reset on occurrence ”in the row corresponding to the feedback information number“ 0 ”set in the feedback information in the table, and whether or not“ Reset on occurrence ”is“ Yes ”. Determine. If the “reset on occurrence” is not “Yes”, the processor 320 advances the process to step S1304.

  When “Reset when occurrence” is “Yes” in step S1303, the processor 320 advances the process to step S1305 to download the feedback bag for the aging test of the display device A as shown in FIG. With reference to the information table 524, the start time information (4000 ms) of the display device A in the header information is referred to, and the reset (restart) of the display device A is waited during the start time. After that, the processor 320 advances the process to step S1304.

  The processor 320 determines whether or not the feedback information number set in the feedback information is a BOOT number, that is, whether or not it is BOOT feedback information (step S1304). For example, when the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A has been downloaded, the processor 320 displays the feedback information number “0” of “BOOT” in the table. And the feedback information number set in the feedback information is also determined to be “0”. If not BOOT feedback information, the processor 320 advances the process to step S1306.

  In the case of BOOT feedback information in step S1304, the processor 320 determines whether or not the display device 150 is turned on by the power control command (POWER_ON) immediately before the BOOT feedback information has been received within the startup time of the display device 150. Is determined (step S1320). More specifically, the processor 320 confirms that the power control command (POWER_ON) is sent immediately before the log information (BOOT) of (7) in FIG. 9 in the instruction command log file 510 of FIG. recognize. In that case, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and refers to the activation time information (4000 ms) of the header information. To do. Then, the processor 320 compares the startup time information (4000 ms) with the offset time 250 ms of the log information (BOOT) in (7) in FIG. 9, and in this example, 4000 ms> 250 ms, so that the display device 150 It is determined that BOOT feedback information has come within the startup time. If BOOT feedback information comes within the startup time of the display device 150 (normal processing), the processor 320 advances the processing to step S1318.

  On the other hand, in spite of the feedback information of the BOOT, in step S1320, the display device 150 is not turned on by the power control command (POWER_ON) immediately before that, or the boot time of the display device 150 is exceeded. If it is determined that the feedback information has been received (abnormal process), the processor 320 advances the process to step S1322.

  In step S1322, the processor 320 determines whether or not the reset feedback information has been received immediately before the BOOT feedback information (step S1322). More specifically, the processor 320 determines whether or not the reset feedback information is received immediately before the log information (BOOT) of (7) in FIG. 9 in the instruction command log file 510 of FIG. 9, for example. . If reset feedback information has been received immediately before (normal processing), the processor 320 advances the processing to step S1318. If the reset feedback information has not been received immediately before (abnormal process), the processor 320 advances the process to step S1306.

  In step S1306, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. The presence / absence of mail transmission is determined with reference to the column “mail transmission” in the row corresponding to the number. If there is no mail transmission, the processor 320 advances the process to step S1308. In the case of mail transmission, the processor 320 sets the feedback information number set in the feedback information as an option and transmits a mail instruction before reproduction test in which mail information before the reproduction test is edited to the mail transmission program module 514. (Step S1324), the process proceeds to Step S1308.

  FIG. 21A is a diagram illustrating an example of mail information before the reproduction test included in the mail instruction before the reproduction test. In FIG. 21A, (project name) and project name “?????” in the title are the project names (for example, display device A) saved in the RAM 332. YYYY, MM, DD, hh, mm, and ss are the date and time at this time acquired from the OS. (Bug) corresponds to the feedback information number set in the feedback information by referring to the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A. This is the column “e-mail transmission template” in the row. The network PC name “???” is a PC name acquired from the OS. “???. Lst” is the file name of the downloaded command command list 520. The feedback information type “BOOT” refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback bag set in the feedback information. This is an example in which a BOOT of a column “feedback information type name” in a row corresponding to the information number (0) is described. “No. nn: group name” is, for example, information (2) in the figure in which the BOOT of (7) in FIG. 9 is recorded in the command command log file 510 of FIG. “Level 3” refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and is set to the feedback information number set in the feedback information. The corresponding column “Reproducibility Test” in the row.

  In step S1308, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. The presence or absence of moving image capture is determined with reference to the column “moving image capture” in the row corresponding to the number. If there is no moving image capture, the processor 320 advances the process to step S1310. When there is a moving image capture, the processor 320 stores the captured moving image file (extension is .movie) 509 that is the current moving image in the HDD 341 as a captured moving image file (extension is .movie) 511 at the time of feedback. Therefore, a feedback moving image saving instruction is transmitted to the moving image capture program module 512 (step S1326), and the process proceeds to step S1310.

  In step S1310, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. The level is determined with reference to the column “Reproducibility Test” in the row corresponding to the number. In the case of level 1, the processor 320 advances the process to step S1312. If the level is 2 or higher, the processor 320 performs a reproduction test process (step S1328), and the process proceeds to step S1312.

  In step S1312, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. The presence or absence of bug information recording (whether or not bug information is generated) is determined with reference to the column “bug information recording” in the row corresponding to the number. If no bug information is recorded, the processor 320 advances the process to step S1314.

  If there is a bug information record, the processor 320 determines whether or not the feedback information number set in the feedback information is the “TESTER ERROR” number, that is, the “TESTER ERROR” feedback information ( Step S1340). For example, when the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A has been downloaded, the processor 320 displays the feedback information number “TESTER ERROR” in the table. 11 ”is determined, and it is determined whether the feedback information number set in the feedback information is also“ 11 ”. If it is not “TESTER ERROR” feedback information, the processor 320 advances the process to step S1330. In the case of feedback information of “TESTER ERROR” in step S1340, the processor 320 advances the process to step S1342.

  In step S1330, the processor 320 transmits the backup instruction in which the option is set to the backup program module 506, and the process proceeds to step S1314.

Here, the options set in the backup instruction are the following information.
"Reproduced level N and reproduction command log file name (extension .log)" or "no reproduction" which is return information of the reproduction test process (step S1328)
Project name “?????” (project name saved in RAM 332 (for example, display device A))
The software version number of the project name (for example, obtained from the command command list 520 in FIG. 8)
“YYYY, MM, DD, hh, mm, ss” (date and time at this time obtained from the OS)
-Network PC name (PC name obtained from the OS)
-File name of instruction command list 520 (extension is .lst)
“Nn number: group name” (for example, information in (2) in the figure in which the BOOT in (7) in FIG. 9 is recorded in the command command log file 510 in FIG. 9)
• Feedback information type (for example, the feedback information set in the feedback information with reference to the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A downloaded) Column in the row corresponding to the number (0) "Feedback information type name" BOOT)
Automatic test level (for example, the feedback information number set in the feedback information with reference to the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A downloaded) Column in the row corresponding to "Reproducibility test")
• File name of the moving image file captured at the time of feedback (extension is .movie) 511 (file name of the moving image file captured at the time of feedback stored in step S1326. If step S1326 is not processed, it is blank)

  On the other hand, in step S1342, the processor 320 transmits a backup instruction in which options are set to the backup program module 506, and the process proceeds to step S1314.

  The option set in the backup instruction in step S1342 is information obtained by adding the explanatory text input by the tester to the option information in step S1330. As a method for acquiring the explanatory text input by the tester in step S1342, a known method may be applied such that the processor 320 displays an input screen (not shown) on the monitor 120 and accepts text input.

  In step S1314, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. The presence / absence of mail transmission is determined with reference to the column “mail transmission” in the row corresponding to the number. If there is no mail transmission, the processor 320 advances the process to step S1316. In the case of mail transmission, the processor 320 sets the feedback information number set in the feedback information as an option, and transmits a mail instruction after reproduction test in which mail information after the reproduction test is edited to the mail transmission program module 514. (Step S1332), the process proceeds to Step S1316.

  FIG. 21B is a diagram illustrating an example of mail information after the reproduction test included in the mail instruction after the reproduction test. In FIG. 21B, (project name) in the title is the project name (for example, display device A) saved in the RAM 332. YYYY, MM, DD, hh, mm, and ss are the date and time at this time acquired from the OS. (Bug) corresponds to the feedback information number set in the feedback information by referring to the feedback information table 524 for the aging test of the display device A as shown in FIG. 6A. This is the column “e-mail transmission template” in the row. The reproducibility is “reproduced level N” or “no reproduction” information that is return information of the reproduction test process (step S1328). Whether or not the test is continued is determined by referring to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6 (a) and referring to the feedback information number set in the feedback information. Corresponding column “continuation test” in the row.

  In step S1316, the processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and the feedback information set in the feedback information. With reference to the column “continuation test” in the row corresponding to the number, it is determined whether or not there is a continuation test. If there is no continuation test, the processor 320 returns the process to step S1300. If there is a continuation test, the processor 320 transmits a test resumption instruction to the command command transmission program module 518 (step S1318), and returns the process to step S1300.

FIG. 14 is a flowchart showing the procedure of the reproduction test process (step S1328) of the feedback information processing program module 516. The processor 320 refers to the downloaded feedback information table 524 for the aging test of the display device A as shown in FIG. 6A, and corresponds to the feedback information number set in the feedback information. With reference to the level of the column “Reproducibility test” in the row (level 2 or higher), the reproduction command log files 508 (extension is .log) for the number of levels are generated from the instruction command log file 510 (step S1400) ). More specifically, when the level of the referred “reproducibility test” is level 4, for example, the processor 320 generates the following four reproduction command log files as the feature point 2 as described above.
Reproduction command log file of level 1; reproduction log of only the last group transmitted in the command command log file 510.
Reproduction command log file of level 2; reproduction log from the last group transmitted in the command command log file 510.
Level 3 replay command log file; replay log from 30 minutes before the last group sent in the command command log file 510.
Reproduction command log file of level 4; reproduction log from the beginning to the end in the instruction command log file 510 (reproduction test within 1 hour).

  Next, in step S1402, the processor 320 sends a level N reproduction setting instruction for reproducing and setting a reproduction command log file of level N with N (natural number) = 1 to the command command transmission program module 518.

  The processor 320 monitors the feedback information from the display device 150 and the reproduction test end notification from the command command transmission program module 518 (step S1406). When the processor 320 receives the feedback information or the reproduction test end notification, the processor 320 determines whether the feedback information is set to a feedback information number other than “TESTER ERROR” (step S1410).

  In the case of feedback information other than “TESTER ERROR”, the processor 320 generates the same feedback information generated in the same group as the instruction command log (the feedback information number set in the feedback information is received in step S1300). It is determined whether or not the same feedback information as the feedback information number set in the information has come (step S1412).

  When the same feedback occurs in the same group as the instruction command log, the processor 320 returns to the calling process with “reproduced level N and level N reproduction command log file name” as return information (step S1412 → return). ). If the same feedback is not generated in the same group as the command command log, the processor 320 makes a recursive call (recall) in step S1300 (step S1412 → S1418), and the process proceeds to step S1414.

  On the other hand, in step S1410, when the processor 320 receives the feedback information of “TESTER ERROR”, the process proceeds to step S1422 (steps S1410 → S1420 → S1422). In step S1422, the processor 320 accepts a selection as to whether or not reproduction has been performed by a tester. Specifically, the processor 320 opens a sub-window and accepts inputs of “reproduced” and “not reproduced”.

  Next, in step S <b> 1424, the processor 320 determines whether or not reproduction has been performed based on the “reproduced” and “not reproduced” inputs in the subwindow.

  If it is determined in step S1424 that reproduction has been performed, processor 320 advances the process to step S1416, and if not, advances processing to step S1414.

  On the other hand, when the processor 320 receives the reproduction test end notification in step S1410, the process proceeds to step S1414 (steps S1410 → S1420 → S1414). In step S1414, the processor 320 determines whether or not there is a level N reproduction command log file that has not yet been set for reproduction. When all the reproduction command log files of level N are set to be reproduced, the processor 320 sends a test stop instruction to the command command transmission program module 518 in step S1416, and returns to the calling source process with “no reproduction” as return information. (Step S1416 → Return).

  If it is determined in step S1414 that there is a level N reproduction command log file that has not been set for reproduction, the processor 320 sends a test resumption instruction to the instruction command transmission program module 518 in step S1404. In step S1408, the processor 320 sends a level N reproduction setting instruction for reproducing and setting a reproduction command log file of level N incremented (+1) to the command command transmission program module 518, and the process proceeds to step S1406. Proceed.

  FIG. 15 is a flowchart showing the processing procedure of the moving image capture program module 512. When the processor 320 receives a capture control command (CAPTURE_START) from the command command transmission program module 518 (steps S1500 → S1502 → S1504), the processor 320 transmits a control signal to the capture device 160 that is constantly operating during the test, and The capture device 160 is instructed to transmit the moving image data, which is the screen shooting process and the result information, and the process of capturing a series of received moving image data in the ring buffer on the RAM 332 is started (step S1504). After starting the capture of the moving image, the processor 320 returns the process to step S1500.

  When the processor 320 receives the capture control command (CAPTURE_STOP) from the command command transmission program module 518 (steps S1500 → S1502 → S1506), the processor 320 stores the moving image data captured in the ring buffer in the captured moving image file 509 (step S1506). . Then, the processor 320 gives the capture moving image file 509 the capture moving image file name (extension is .movie) set in the capture control command (CAPTURE_STOP) option (step S1508), and returns the processing to step S1500. .

  When the processor 320 receives a feedback moving image saving instruction from the feedback information processing program module 516 (steps S1500 → S1502 → S1510 → S1512), the captured moving image file (extension is .movie) that is the current moving image. 509 is stored in the HDD 341 as a capture moving image file (extension is .movie) 511 at the time of feedback (step SS1512). Then, the processor 320 returns the process to step S1500.

  FIG. 16 is a flowchart showing the processing procedure of the mail transmission program module 514. When the processor 320 receives the pre-reproduction test e-mail instruction (steps S1600 → S1602 → S1604), the processor 320 sends an e-mail containing the pre-reproduction test e-mail information (see, for example, FIG. 21A) included in the pre-reproduction test e-mail instruction as a text. Create (step S1604). Then, the processor 320 advances the process to step S1606.

  When the processor 320 receives the mail instruction after the reproduction test (steps S1600 → S1602 → S1608 → S1610), the mail information after the reproduction test included in the mail instruction after the reproduction test (see, for example, FIG. 21B) The created email is created (step S1610). Then, the processor 320 advances the process to step S1606.

  In step S1606, the processor 320 uses the feedback information number set as an option in the pre-reproduction mail instruction or the post-reproduction mail instruction as an index to download the display device as shown in FIG. Referring to the feedback information table 524 for the aging test of A, the column “mail destination” in the row corresponding to the feedback information number is set to the created mail, and the mail is transmitted to the mail server 375. Then, the processor 320 returns the process to step S1600.

  FIG. 17 is a flowchart showing the processing procedure of the backup program module 506. Upon receiving the backup instruction (steps S1700 → S1702), the processor 320 edits the information on the bug information sheet as a result of the reproduction test based on the options set in the backup instruction.

  FIG. 22 is a diagram illustrating an example of a bug information sheet. In particular, when the option set in the backup instruction is “reproduced level N and reproduction command log file name (extension .log)” which is the return information of the reproduction test process (step S1328), the bug information sheet of FIG. In the reproducibility item, ““ Reproduced at level N ”Reproduction command log file name“ ???. Log ”” is edited.On the contrary, the option set in the backup instruction is the reproduction test processing In the case of “no reproduction” which is the return information of (Step S1328), the bug information sheet of FIG. 22 includes an instruction command log file name “???. Log” in the reproducibility item “not reproduced”. "Is edited.

  Next, the processor 320 generates a bug information file including information on the bug information sheet, the reproduction command log file 508 (or the command command log file 510), and the capture moving image file 511 at the time of feedback (step S1704). The file is transmitted to the file server 373, and the bug information is backed up (step S1706). Then, the processor 320 returns the process to step S1700.

  FIG. 18 is a flowchart showing the processing procedure of the power supply control program module 526. Upon receiving the power control command (step S1800 → S1802), the processor 320 turns on / off the power switch 105 based on the power control command (POWER_OFF or POWER_ON) (step S1802). Then, the processor 320 returns the process to step S1800.

  FIG. 19 is a flowchart showing the processing procedure of the file management program 528. When the processor of the file server 373 receives the instruction command list request (steps S1900 → S1902 → S1910), the processor of the command command list 520 corresponding to the project name (for example, display device A) set as an option in the instruction command list request. It transmits to PC110 (step S1910). Then, the processor 320 returns the process to step S1900.

  Further, when the processor of the file server 373 receives the feedback information table request (steps S1900 → S1902 → S1904 → S1912), the project name (for example, display device A) and the type (optional) set in the feedback information table request For example, the feedback information table 524 corresponding to aging is transmitted to the PC 110 (step S1912). Then, the processor 320 returns the process to step S1900.

  When the processor of the file server 373 receives the bug information file (steps S1900 → S1902 → S1904 → S1906 → S1914), the bug information file is stored in the HDD and the bug information is backed up (step S1914). Then, the processor 320 returns the process to step S1900.
