Description

  The present invention relates to a program and a vehicle production line management system.

  Conventionally, various techniques have been proposed for automatically eliminating an error that occurs in an information processing apparatus when an operator is absent. For example, in Patent Document 1, an application program failure is determined when a predetermined log message appearing in a process log file has an appearance frequency equal to or higher than a predetermined number of times, and the application program failure is associated with the determined application program failure in advance. A technique for executing the corresponding process is disclosed.

JP 2005-267434 A

  In the technique of Patent Document 1 described above, when a recovery process is performed after determining that an application program failure has occurred, when there is no process to be monitored related to the application program, a specific log message appears in the log file of the application program. In the case where the frequency exceeds a certain threshold, the case where the log file of the application program has not been updated for a predetermined time or more is illustrated.

  When the application program failure actually occurs, the above-described countermeasure is effective, but there are cases where the processing does not proceed even in a category that can be regarded as the normal processing of the application program. For example, an application program having a user interface executed in the information processing apparatus may wait for an operator's operation input while displaying an error message.

  There is no problem as long as the operator is monitoring the display unit near the information processing device to the point where the operation message can be input immediately at the time when the error message is displayed. It may be left for a long time with the message displayed. During this time, the application program that displayed the error message may not be able to execute other processing according to the request even if any request is input, and may fail to cooperate with other application programs or other information processing devices. is there.

  Such a failure of cooperation may cause a failure in information transmission between the system and the site in a system such as a vehicle production line that produces a single product through a flow operation performed in close cooperation between processes. Yes, necessary production instructions do not reach the site and may cause production failure. In addition, there is a possibility that the accumulation of necessary information to be acquired from the field or the like in the system database will fail, resulting in data omission or leakage.

  The present invention has been made in view of the above-described problems. An application program used in a system such as a vehicle production line can be regarded as a normal process of the application program, and any request is input in response to the request. Another object of the present invention is to eliminate the state where other processes are not executed and to facilitate the cooperation with other application programs and other information processing apparatuses.

  One aspect of the present invention is executed in a first information processing unit in which an application program for reading and writing data from and to a database storing vehicle information accessed by a plurality of terminals arranged in the vicinity of the vehicle production line is executed. A first function for finding an error output of the application program, and a second function for forcibly terminating and restarting the application program for which an error output has been found by the first function. A computer-readable program that is characterized.

  By using the program configured as described above, when an application program that reads / writes data to / from a database that stores vehicle information accessed by a plurality of information processing units arranged near the vehicle production line outputs an error, the application that has output the error Forcibly terminates and restarts automatically, so that application programs used on the vehicle production line can be regarded as normal processing of the application program. It is possible to automatically eliminate the state where the process is not executed, and to reduce the occurrence of a situation in which the application program cannot be linked to another application program or another information processing unit.

  One of the optional aspects of the present invention is that the first function outputs an error output of the application program based on the presence / absence of a popup error dialog box formed by the application program and the message content of the popup error dialog box. The second function is a computer-readable program characterized in that the application program is forcibly terminated by pseudo-clicking a button in the pop-up error dialog box.

  By using the program configured in this way, the application program automatically detects the occurrence of an error that is notified by forming a popup error dialog box, and executes the forced termination from the popup error dialog box. Since the application program is restarted after the program is terminated, the application program can be forcibly terminated and restarted while minimizing the influence on the application program and data handled by the application program.

  One of the optional aspects of the present invention is an inspection in which first identification information acquisition means installed along the vehicle production line retains vehicle identification information acquired from a work vehicle conveyed on the vehicle production line. A first application program that is one of the application programs executed in the first information processing unit acquires the vehicle identification information from the system, and the first application program is vehicle information corresponding to the vehicle identification information. Is acquired from the second information processing unit and registered in the database including the vehicle identification information, and at least one of the terminals accesses the database to access the database of the work vehicle conveyed on the vehicle production line. Information stored in association with vehicle identification information is acquired. A possible program.

  By using the program configured as described above, the period during which the first application program is not operated can be shortened as much as possible, and the probability that the registration of the vehicle identification information in the database will fail in the vehicle production line is reduced. It is possible to reduce the probability of losing sight of the position of the work vehicle that is transported above, or to cause a shift in the inspection or work instruction that is issued based on the vehicle information stored in the database.

  One of the optional aspects of the present invention is an inspection in which second identification information acquisition means installed along the vehicle production line retains vehicle identification information acquired from a work vehicle conveyed on the vehicle production line. A second application program, which is one of the application programs executed in the first information processing unit, acquires the vehicle identification information from the system, and the second application program stores the vehicle identification information on the database. The position information included in the corresponding vehicle information is updated to a position corresponding to the second identification information acquisition unit, and at least one of the terminals accesses the database and is connected to the vehicle production line. Information stored in association with the vehicle identification information is acquired. A possible program.

  By using the program configured as described above, the period during which the second application program is not operated can be shortened as much as possible, and in the vehicle production line, the probability of failing to update the vehicle identification information to the database is reduced, and the vehicle production line It is possible to reduce the probability of losing sight of the position of the work vehicle that is transported above, or to cause a shift in the inspection or work instruction that is issued based on the vehicle information stored in the database.

  One of the optional aspects of the present invention is that at least one of the terminals is configured to input an operation input for registering a work vehicle to be withdrawn from the middle of the inspection process of the vehicle production line, and the vehicle production line. A third application which is one of the application programs executed in the first information processing unit, which receives an operation input for registering a work vehicle to be returned to the line in the middle of the inspection process and registers it in the database. The program creates work delay information corresponding to the information related to evacuation or return of the work vehicle and registers it in the database, and at least one of the terminals accesses the database to check the vehicle production line A computer characterized by acquiring work delay information relating to a vehicle being transported and displaying it on a display unit It is taken possible program.

  By using the program configured as described above, the period during which the third application program is not operated can be shortened as much as possible, and the situation where the work vehicle evacuated outside the line from the middle of the inspection process of the vehicle production line is not registered in the database. In the inspection process of the vehicle production line, avoiding the situation that the work vehicle returned to the line in the line is not registered in the database, the position of the work vehicle transported on the vehicle production line is lost or accumulated in the database It is possible to reduce the probability that a deviation in the inspection or work instruction issued based on the vehicle information will occur. In addition, it is possible to eliminate as much as possible the situation in which the worker or the work facility cannot grasp the work delay of the work vehicle.

  One of the optional aspects of the present invention is that a fourth application program, which is one of the application programs executed in the first information processing unit, is subjected to a predetermined inspection in a step before an inspection step in the vehicle production line. Information indicating whether or not the vehicle is a target of the vehicle is registered in the database as one of the vehicle information, and at least one of the terminals accesses the database to access the work vehicle. Is a computer-readable program characterized in that information indicating whether or not a subject has been subjected to the predetermined inspection is acquired and displayed on a display unit.

  By using the program configured as described above, the period during which the fourth application program is not operated can be shortened as much as possible, and whether or not the work vehicle is a target of a predetermined inspection executed by the fourth application program at a specific timing of the inspection process. The period during which such a determination cannot be made can be shortened as much as possible, and so-called sampling inspections that are performed only on some vehicles both in the process prior to the inspection process and in the inspection process should be performed as reliably as possible in the inspection process. Is possible.

  One of the selective aspects of the present invention is that a fifth application program, which is one of the application programs executed in the first information processing unit, is a change in inspection specification applied to inspection equipment in the inspection process. When the change of the inspection specification is found, the change content is registered in the database together with the change date and time.

  By using the program configured in this way, the period during which the fifth application program is not running can be shortened as much as possible, and changes in inspection specifications are reflected in the database as reliably as possible, causing problems when analyzing inspection results. The possibility can be reduced.

Hereinafter, the present invention will be described in the following order.
(A) First embodiment:
(B) Second embodiment:
(C) Third embodiment:
(D) Fourth embodiment:
(E) Fifth embodiment:

(A) First embodiment:
FIG. 1 is a diagram illustrating an overview of a vehicle production line according to the present embodiment, and FIG. 2 is a diagram illustrating an overview of a vehicle production line management system according to the present embodiment.

  The vehicle production line L is provided with a plurality of processes from upstream to downstream of the line according to the assembly order and work order of the vehicle, and conveys the work vehicle W from upstream to downstream.

  In the vehicle production line L, for example, four processes of a vehicle body process L1, a painting process L2, an assembly process L3, and an inspection process L4 are arranged from upstream to downstream of the line.

  Each process is generally further divided into a plurality of work sections (process sections), and in each work section, devices, equipment, and personnel corresponding to the work contents of the section are arranged.

  In the vicinity along the vehicle production line L, a plurality of terminals 10 as information processing apparatuses are arranged. The terminal 10 is connected to the database 30 managed by the host computer 20 as the first information processing unit in a wireless or wired manner so that the information acquired from the database 30 is displayed on the display unit or the acquired information is displayed. Based on this, control processing for various facilities is executed.

  The host computer 20 is configured by one or a plurality of information processing apparatuses connected to be communicable with each other. When the host computer 20 is configured by a plurality of information processing apparatuses, the application program is a plurality of information processing apparatuses in units of processing functions. The monitoring program 22, which will be described later, may also be operated on an information processing apparatus different from the information processing apparatus on which the application program operates.

  The terminal 10 does not have to be in the form of a computer such as a personal computer as long as it has a communication function and an information processing function, and may be realized in the form of equipment, for example. Another system or the host computer 20 may be interposed between the terminal 10 and the database 30.

  The terminal 10 receives information input from various facilities and information input performed by an operator such as an operator via the operation unit. Information input to the terminal 10 is appropriately transmitted to the database 30 and stored in the database 30.

  The terminal 10 requests and acquires necessary information from the plurality of vehicle information 31 stored in the database 30 and displays it on the display unit, or executes control processing for various facilities based on the acquired information.

  The vehicle information 31 includes, for example, vehicle identification information 41, vehicle specification information 31a indicating various specifications relating to vehicle production, vehicle position information 31b indicating the position of the work vehicle W in the vehicle production line L, and inspection of the work vehicle W. The vehicle inspection condition information 31c indicating the contents of inspection performed in the process L4 and the like, vehicle delivery date information 31d, vehicle inspection result information 31e indicating various defects occurring on the vehicle production line L, and the like are configured.

  In the host computer 20, an application program 121 (AP 121) that performs various processes such as registration, update, change, analysis, and the like regarding the vehicle information 31 in the database 30 is executed.

  When a predetermined error occurs, the AP 121 pops up a dialog box that stops processing and notifies the error. During this pop-up display, the AP 121 is in a state where it cannot execute processing according to the request even if any request is input from another application program or another information processing unit.

The following four patterns are exemplified when the predetermined error occurs in the AP 121.
(1) When registration or update in the database 30 fails due to competition among a plurality of application programs executed on the host computer 20 (2) An application program executed on the host computer 20 fails to communicate due to a communication error (3) A plurality of application programs executed on the host computer 20 configured to exclusively access a specific file fail exclusive access timing control, and a plurality of application programs simultaneously access the specific file. As a result of rewriting or the like, when one or a plurality of application programs fail to process the specific file (4) When processing for referring to invalid data written for some reason in the database 30 is performed

  As an example of the case of (1) described above, a plurality of application programs that perform the same information on the database 30 as update targets are executed at regular intervals by a timer. Although the timer is set so that the processing is not executed at the same time, another application program may fail to update the same target information due to the processing time, and may stop with an error output.

  As an example of the case (2) described above, the terminal 10 disposed along the vehicle production line L and / or the terminal 10 and the database 30 are interposed during the operation of the application program of the host computer 20. If the other system is unexpectedly inactive or the application program is unexpectedly operated, the application program may output an error due to a communication error and stop. For example, when the terminal 10 and / or the other system described above is unexpectedly inactive or the application program is unexpectedly operated, for example, the terminal 10 and / or the above-mentioned other than the host computer 20 on the day before the holiday If the system is shut down, etc. An error output due to a communication error occurs during a period in which the application does not operate normally unless a return process for eliminating the error is performed before the line operation start timing on the next operating day.

  An example of the case of (3) described above is a case where a plurality of application programs are configured to exchange information via one work data. Specifically, the first application program In this case, information is acquired from an information processing unit other than the host computer 20 and stored in a predetermined file, and the second application program accesses the same predetermined file to acquire information and register it in the database. In such a case, while one application program accesses, the predetermined file is locked by the one application program, but in rare cases, both access to the predetermined file in the unlocked state may be established. There is a possibility that one of the application programs will output an error and stop.

  As an example of the case (4) described above, there is a case where illegal data is written in the information stored in the database 30 due to a human operation error or a program bug.

  In the host computer 20, a monitoring program 22 for monitoring the AP 121 (and / or an application program described in at least one of the embodiments described later) is executed. In the present embodiment, a case where the monitoring program 22 monitors the AP 121 will be described.

  FIG. 3 is a diagram for explaining the flow of processing of the monitoring program 22. The monitoring program 22 includes a first function 22a for finding an error output of the AP 121, and a second function 22b for forcibly terminating and restarting an application program for which the first function 22a has found an error output.

  The first function 22a periodically acquires a list of windows formed by the AP 121 (S1), and determines whether a predetermined pop-up error dialog box is included in the list (S2).

  If the list includes a predetermined pop-up error dialog box (S2: Yes), the second function 22b executes forced termination and restart of the application (S3 to S8), and the list includes a predetermined pop-up error dialog box. If not included (S2: No), monitoring of error output is continued (S1 to S2). Thereby, the first function 22a monitors the popup of a predetermined popup error dialog box by the AP 121.

  The monitoring program 22 associates the window name of the predetermined pop-up error dialog box displayed when the predetermined error described above is displayed when the AP 121 notifies the error in advance with the message content displayed in the pop-up error dialog box. keeping.

  The first function 22a includes a predetermined pop-up error dialog box for notifying a predetermined error in the list using the window name and the message content displayed in the pop-up error dialog box as a clue for the list of windows formed by the AP 121. Judge whether or not.

  When the first function 22a detects a pop-up of a predetermined pop-up error dialog box by the AP 121 (S2: Yes), the second function 22b outputs a command for performing a pseudo click operation on the operation button of the pop-up to force the AP 121 Termination is performed via a predetermined pop-up error dialog box (S3).

  Thereafter, the second function 22b sequentially determines whether or not the AP 121 has been stopped (S4) and whether or not the error of the AP 121 is due to incorrect data writing (S6), and stops the AP 121 completely. (S5), after deleting the illegal data causing the error (S7), the AP 121 is restarted (S8).

  That is, if the AP 121 is stopped (S4: Yes) and it is not an error due to the writing of illegal data (S6: No), a command to perform a pseudo click operation is output, and then the AP 121 is restarted (S8).

  If the AP 121 is not stopped by a pseudo click operation command (S4: No), the AP 121 is forcibly terminated (S5), and unauthorized data is searched and deleted as necessary (S6, S6). S7), the AP 121 is restarted (S8).

  When the restart of the AP 121 is completed, the monitoring program 22 repeatedly executes the processes of steps S1 to S2 for finding the error output by the first function 22a again.

  As described above, in the present embodiment, when the forced termination is performed, the AP 121 is first forcibly terminated through a predetermined pop-up error dialog box displayed by the function of the AP 121. Therefore, the influence on the data handled by the AP 121 and the AP 121 is affected. Can be minimized. In addition, only when the AP 121 is not terminated, the AP 121 is forcibly terminated by another method that can reliably terminate the AP 121, so that the AP 121 is forcibly terminated. In addition, since the configuration is such that the retrieval and deletion of illegal data is performed as necessary after the AP 121 has been securely terminated, a similar error does not occur after the AP 121 is restarted, and the AP 121 is reliably terminated. Since the deletion of illegal data is not executed before, the probability that a new error occurs or the deletion of illegal data ends unsuccessfully is reduced as much as possible.

(B) Second embodiment:
FIG. 4 is a diagram showing an outline of a vehicle production line management system according to the present embodiment. In the outline of the vehicle production line management system shown in FIG. 4, the same reference numerals are given to the same components as those in the second embodiment, and detailed description thereof will be omitted below.

  In the vehicle production line according to the present embodiment, a check device 40 as a first identification information acquisition unit and / or a second identification information acquisition unit that monitors the passage of the work vehicle W is provided at a necessary place along the vehicle production line L. It is arranged. The check device 40 is connected to a terminal 10 installed nearby in a wireless or wired manner so as to be communicable.

  The check device 40 acquires the vehicle identification information 41 from a vehicle passing through the vehicle production line L near the installation location, transmits the acquired vehicle identification information 41 to the terminal 10, and transmits the acquired vehicle identification information 41 to the inspection system 70 via the terminal 10. . The AP 221 operating on the host computer 20 periodically accesses the inspection system 70 and acquires the vehicle identification information 41 held by the inspection system 70.

  The vehicle identification information 41 is information unique to each vehicle transported on the vehicle production line L, and is vehicle identification information such as an ID tag attached to the work vehicle W, a QR code (registered trademark), a barcode, and an RFID. It is held by the work vehicle W by the holder 50.

  The host computer 20 is connected to another information processing unit via a communication line so as to be communicable wirelessly or by wire. For example, the host computer 20 functions as a production management system 60 as a second information processing unit that manages vehicle order information (including information such as vehicle type and specifications) and as a third information processing unit that holds vehicle inspection results. The inspection system 70 is connected to be communicable wirelessly or by wire.

  When the host computer 20 receives the vehicle identification information 41 from the inspection system 70, the host computer 20 acquires information related to the vehicle identification information 41 from other information processing units as necessary, and monitors the monitoring device 40 that is the transmission source. The information acquired from the vehicle identification information 41 and other information processing units is stored in a predetermined storage area of the database 30 together with the position information indicating “”.

  For example, the host computer 20 associates the vehicle information 31 received from the inspection system 70 and the vehicle information 31 acquired from another information processing unit in relation to the vehicle information 31 with the vehicle identification information 41 in the database 30. The vehicle information 31 registered or stored in the database 30 is updated.

  In the vehicle production line management system according to the present embodiment, in particular, the first application program that accesses the inspection system 70 to acquire the vehicle information 31 and registers and updates the vehicle information 31 in the database 30 and / or the second application program. The operation of the AP 221 as a second application program is monitored.

  When newly registering the vehicle identification information 41 acquired from the inspection system 70 in the database 30, the AP 221 identifies the vehicle identification to the production management system 60, which is an external information processing unit that stores the specification information of the ordered vehicle. The vehicle specification information 31a corresponding to the information 41 is inquired and acquired, and is created based on the vehicle identification information 41, the vehicle specification information 31a, and the position information corresponding to the monitoring location of the check device 40 that acquired the vehicle identification information 41. The vehicle position information 31b is associated and stored in a predetermined storage area of the database 30.

  The AP 221 periodically acquires vehicle information 31 registered in the database 30 and information acquired from other systems connected via a communication line, and generates new vehicle information 31 relating to each work vehicle W to generate a database. Register 30. For example, in the vehicle production line L, an automatic sticking device in which various automatic devices automatically stick labels to the work vehicle W, and an automatic inspection device that performs a predetermined inspection on the work vehicle W are arranged. . The vehicle production line L may mix a plurality of types of work vehicles W having different specifications. The automatic sticking device and the automatic inspection device stick the work vehicle W to be loaded next into the device based on the vehicle identification information 41 read by the same device as the check device 40 described above, the transport order, and the transport timing. Information on the specifications and inspection specifications is accessed by accessing the database 30.

  Here, if the AP 221 outputs a pop-up error dialog box and stops processing, the necessary vehicle information 31 of the new work vehicle is not registered in the database 30 or the vehicle position information 31b of the work vehicle is appropriately set. It may not be updated. In addition, if the vehicle information 31 required by the terminal 10 arranged along the vehicle production line L cannot be acquired from the database 30, the operation cannot be performed and the vehicle production line L stops.

  In the host computer 20, the monitoring program 22 monitors the AP 221. In the monitoring program 22, the first function 22a detects an error output of the AP 221 and the second function 22b forcibly terminates and restarts the AP 221 in the same flow as in the first embodiment described above.

  As described above, the monitoring program 22 according to the present embodiment monitors the output of the pop-up error dialog box of the AP 221 and appropriately terminates and restarts the AP 221 so that the position of the work vehicle conveyed on the line is related. Confusion caused by information not being registered or updated in the database 30 can be prevented, and the vehicle production line L can be prevented from stopping.

(C) Third embodiment:
FIG. 5 is a diagram showing an outline of a vehicle production line management system according to the present embodiment. In the outline of the vehicle production line shown in FIG. 5, the same reference numerals are given to the same components as those in the second embodiment, and detailed description thereof will be omitted below.

  In the vehicle production line L according to the present embodiment, a worker drives the work vehicle W in which a defect or the like has been found in the inspection process L4 to evacuate from the middle of the line, and the work vehicle is ejected as a terminal. The evacuation information 31g such as the vehicle identification information 41, the evacuation date and time, the evacuation reason, etc. is directly registered in the database 30 by the operation input to the ten operation units.

  When the trouble of the vehicle evacuated out of the line is resolved and the vehicle is returned to the line from the middle of the line, the operator falls under the list of evacuated vehicles displayed on the screen of the terminal 10 And the return information 31h such as the return position to the line and the return date and time is directly registered in the database 30 by an operation input to the operation unit of the terminal 10.

  In the vehicle production line management system according to the present embodiment, the host computer 20 executes an AP 321 as a third application program. The AP 321 periodically accesses the database 30, acquires vehicle position information 31 b, delivery date information 62, evacuation information 31 g and return information 31 h included in the vehicle information 31 accumulated in the database 30, and schedules the operation of the vehicle production line L Information 481 is acquired from the production management system 480, work delay information 423 for each vehicle is created based on these information, and the vehicle information 31 of the vehicle is registered in the database 30.

  The terminal 10 receives, for example, the work delay information 423 of the work vehicle in the work section (process section) corresponding to the terminal 10 from the database 30 and displays it on the display unit.

  In this embodiment, the monitoring program 22 executed on the host computer 20 monitors the AP 321. In the monitoring program 22, the first function 22a detects an error output of the AP 321 and the second function 22b performs the forced termination and restart of the AP 321 in the same flow as in the first embodiment described above.

  As described above, in this embodiment, the monitoring program 22 monitors the output of the pop-up error dialog box of the AP 321 and forcibly terminates the AP 321 as appropriate to restart it. Therefore, the work delay information 423 is not registered in the database 30 or updated. It is possible to prevent the vehicle production line from being disrupted or stopped due to the failure of the vehicle.

(E) Fourth embodiment:
FIG. 6 is a diagram showing an outline of a vehicle production line management system according to the present embodiment. In the outline of the vehicle production line shown in FIG. 6, the same reference numerals are given to the same components as those in the second embodiment, and detailed description thereof will be omitted below.

  In the vehicle production line management system according to the present embodiment, the host computer 20 executes an AP 421 as a fourth application program.

  When the AP 421 detects the introduction of a new work vehicle to the inspection process L4, the AP 421 registers in the database 30 the inspection necessity information 31j relating to the necessity of the predetermined inspection for the new work vehicle as the vehicle information 31 of the work vehicle.

  Detection of the introduction of a new work vehicle into the inspection process L4 can be performed based on, for example, periodically accessing the database 30 and registering the new work vehicle in the database 30. Registration of a new work vehicle in the database 30 is performed by, for example, the AP 221 described in the second embodiment.

  For example, the AP 421 accesses, for example, the production management system 480 as a third information processing unit that holds vehicle information related to the process prior to the inspection process L4, and whether the new work vehicle carried in is selected as a target for the predetermined inspection. Inspection necessity information 31j indicating whether or not is acquired.

  An example of the predetermined inspection is a so-called sampling inspection. By carrying out the sampling inspection appropriately, it is possible to efficiently carry out unnecessary inspections up to 100% inspection. Moreover, the change in the intermediate process can be managed by performing the same inspection several times before the selected work vehicle is completed. This leads to optimization and improvement of each process.

  The terminal 10 receives, for example, the inspection necessity information 31j of the sampling inspection of the work vehicle in the work section (process section) corresponding to the terminal 10 from the database 30, and displays it on the display unit.

  In the present embodiment, the monitoring program 22 executed on the host computer 20 monitors the AP 421.

  As described above, in this embodiment, the monitoring program 22 monitors the output of the popup error dialog box of the AP 421, and appropriately terminates the AP 421 and restarts it appropriately, so that the inspection necessity information 31j for the predetermined inspection is registered in the database 30. By not being performed or updated, a problem that a necessary inspection is not performed is avoided.

(F) Fifth embodiment:
FIG. 7 is a diagram showing an outline of a vehicle production line management system according to the present embodiment. In addition, in the outline | summary of the vehicle production line shown in FIG. 7, the same code | symbol is attached | subjected to the same structure as 2nd Embodiment, and detailed description is abbreviate | omitted below.

  In the vehicle production line management system according to the present embodiment, the host computer 20 executes an AP 521 as a fifth application program.

  The AP 521 periodically accesses one or a plurality of inspection facilities 690 provided in the vehicle production line L, and acquires the date and time of change of the inspection specification of the inspection performed by the inspection facility 690 and the content of the change of the inspection specification. And stored in the database 30.

  The inspection facility 690 changes the inspection specification regularly or irregularly, performs inspection with the changed inspection specification, and outputs inspection data. The inspection data includes information on the inspection date, vehicle type inspected, and inspection result.

  For example, the AP 521 periodically acquires the inspection specification definition data 691 as data to be referred to when the inspection facility 690 performs the inspection from the inspection facility 690 and registers it in the database 30. The inspection specification definition data 691 includes an inspection specification change date (or version information) and inspection specification change contents.

  The change contents of the inspection specification included in the inspection specification definition data 691 stored in the database 30 become master information when the inspection data is analyzed. The analysis of the inspection data needs to be performed by making the update date / time of the inspection specification definition data 691 and the creation date / time of the inspection data correspond to each other. The inspection data created by the inspection facility 690 before the update of the inspection specification is the inspection before the update. The specification definition data 691 is analyzed as master information, and the inspection data created by the inspection facility 690 after the inspection specification is updated needs to be analyzed using the updated inspection specification definition data 691 as master information.

  The AP 521 acquires the inspection result data 692 held by the inspection facility 690, and analyzes it by combining with the inspection specification definition data 691 registered in the database 30. Inspection result data 692 includes date and time, vehicle type, and inspection result. The AP 521 refers to the date and time included in the inspection result data 692, acquires the inspection specification definition data 691 corresponding to the date and time from the database 30, and analyzes the inspection result. Therefore, if there is a defect in the update of the inspection specification definition data 691 stored in the database 30, a mismatch occurs between the inspection specification used for the inspection and the inspection specification definition data 691 used as analysis master information. May fail or incorrect analysis results may be output.

  In the host computer 20, the monitoring program 22 monitors the AP 521. In the monitoring program 22, the first function 22a finds an error output of the AP 521 and the second function 22b performs forced termination and restart of the AP 521 in the same flow as in the first embodiment described above.

  As described above, the monitoring program 22 according to the present embodiment monitors the output of the pop-up error dialog box of the AP 521, and appropriately terminates the AP 521 and restarts it, so that the inspection specification definition follows the change of the inspection specification. The data 691 is appropriately stored in the database 30, and the probability that the analysis of the inspection result fails can be reduced as much as possible.
