Description

  The present invention relates to a maintenance work mistake prevention program and a maintenance work mistake prevention method for checking permission during maintenance work of an apparatus.

  Conventionally, in the maintenance work of a computer system, the power of the maintenance target device or system is turned off or the maintenance panel is operated without obtaining the administrator's permission. Sometimes happened. Prior to maintenance to prevent such mistakes, maintenance personnel were thoroughly trained to receive approval from the administrator.

Further, there is a technique in which a maintenance / inspection work route is formed by a plurality of IC tags, and a robot moves along the maintenance / inspection work route to perform maintenance / inspection (Patent Document 1).
JP 2003-232881 A

  In the former technique described above, it is necessary to perform the predetermined maintenance inspection by turning off the power of the device or operating the operation panel after obtaining the approval of the administrator during the maintenance inspection of the computer system. There is a problem that it is difficult to prevent the great influence on the user work due to mistakes during the maintenance work, without failing to rely on the education of obtaining the approval of the administrator.

  Further, in the latter technique described above, only maintenance work is performed by forming a maintenance / inspection work route with a plurality of IC tags, and the maintenance worker's prior approval of the maintenance work is obtained from the administrator. Therefore, there is a problem that it is difficult to prevent the great influence on the user work due to mistakes during the maintenance work.

  In order to solve these problems, the present invention asks the administrator to write maintenance work permission information on the IC tag, and turns on the work permission flag when the permission information is read from the IC tag at the time of maintenance and inspection of the apparatus. Further, the object is to enable maintenance by setting a flag on when the apparatus is not in operation.

  Therefore, maintenance can be performed by turning on the work permission flag when permission information is read from the IC tag during maintenance inspection of the device, and enabling maintenance by turning on the flag when the device is not in operation. If the personnel do not have an IC tag in which maintenance work permission is written, maintenance work cannot be started, and maintenance work mistakes can be completely prevented.

  The present invention allows the administrator to write permission information for maintenance work on the IC tag, enables maintenance by turning on the work permission flag when permission information is read from the IC tag during maintenance inspection of the apparatus, Since the system is set to enable maintenance by turning on the flag when the system is not in operation, maintenance personnel cannot start maintenance work without an IC tag to which maintenance work permission is written, and complete maintenance work mistakes. Can be prevented.

  The present invention enables maintenance by turning on a work permission flag when permission information is read from an IC tag during maintenance inspection of the apparatus, and enables maintenance by turning on the flag when the apparatus is not in operation. Has been able to start maintenance work without an IC tag to which maintenance work permission has been written, and has completely prevented mistakes in maintenance work.

  FIG. 1 shows a system configuration diagram of the present invention.

  In FIG. 1, an IC tag 1 can write and store data wirelessly and read data, and stores data such as a maintenance permit 2 here (see FIG. 6). .

  The maintenance permit 2 is an example of information written in the IC tag 1 and is information for permitting maintenance of the system (computer system).

  The IC tag reading unit 3 is attached to the system, and reads data such as the maintenance permit 2 from the IC tag 1 wirelessly (or takes in the read data).

  The work permission setting unit 4 sets the work permission FF 5 to ON when the maintenance permit 2 is read by the IC tag reading unit 3 so that the power can be turned off and the maintenance panel can be operated.

  When set to ON, the work permission FF 5 enables the power key 6 to be pressed to turn off the power or to operate the maintenance panel 9.

  The AND circuits 7 and 10 are for enabling the operation of the power key 6 and the maintenance panel 9 when the work permission FF 5 is set to ON (work permission).

  The power source 8 is a power source that is supplied to the system 11 and is configured to be turned off when the power key 6 is pressed.

  The maintenance panel 9 is a panel for performing various instructions and operations for performing maintenance.

  The system 11 is a computer system, and various systems using computers such as servers and ATMs.

  Next, the operation of the configuration of FIG. 1 will be described in detail according to the order of the flowchart of FIG.

  FIG. 2 shows a flowchart for explaining the operation of the present invention.

  In FIG. 2, S1 reads IC tag information. The IC tag reading unit 3 provided in the system 11 of FIG. 1 reads IC tag information from the IC tag 1 held by maintenance personnel.

  In S2, it is determined whether there is a maintenance permit. This determines whether or not there is a maintenance permit in the IC tag information read from the IC tag 1 in S1. If YES, the work permission FF 5 is turned on in S 3, and the operation of the power key 6 and the maintenance panel 9 is validated. Then, maintenance work is started. On the other hand, in the case of NO in S2, since it has been found that there is no maintenance permit in the IC tag information read from the IC tag 1, the work permission FF5 is turned off in S4 and the power key 6 and the maintenance panel 9 are switched. The operation is invalidated so that maintenance work cannot be performed, and a great influence due to power interruption or the like is not exerted on the user of the system 11.

  As described above, if there is a maintenance permit in the IC tag information read by the IC tag reader 3 of the maintenance target system 1 for the IC tag held by the maintenance worker, the work permission FF5 is turned on. The power key 6 and the maintenance panel 9 can be operated, and maintenance personnel can operate the power key 6 and the maintenance panel 9 to perform maintenance work. At this time, if the IC tag 1 does not have a maintenance permit, the power key 6 and the maintenance panel 9 cannot be operated, and the IC tag 1 in which the maintenance permit is written is not received from the administrator of the system 11 (or brought with you). If the maintenance permit information is not written to the IC tag by the administrator, the maintenance work cannot be performed, and it is possible to prevent an unexpected power cut or system stoppage.

  FIG. 3 shows another system configuration diagram of the present invention. In addition to the system configuration diagram of FIG. 1, an operating setting unit 12 and a maintenance enable determination unit 16 are provided so that maintenance work cannot be performed while the system 11 is operating. 1 to 9 are the same as 1 to 9 in FIG.

  In FIG. 3, the operating setting unit 12 invalidates maintenance work while the system 11 is operating, and is configured from an operating setting processing unit 13, an operating FF 14, a NAND circuit 15, and the like. Is.

  The operating setting processing unit 13 sets the operating FF 14 to ON when it detects that the system 11 is operating, and sets the operating FF 14 to OFF when it detects that the system 11 is not operating.

  The operating FF 14 stores ON when the system 11 is operating and stores OFF when the system 11 is not operating.

  The NAND circuit 15 inverts the output of the operating FF 14 and is OFF when the operating FF 14 is ON (indicating that the system 11 is operating) (the system 11 is operating and maintenance work is not possible). State), or when the FF 14 in operation is OFF (indicating that the system 11 is not in operation) and ON (indicating a state in which the system 11 is not in operation and maintenance work is possible). is there.

  The maintainability determination unit 16 determines whether or not maintenance is possible. The AND circuit 17 performs a logical operation on the output from the NAND circuit 15 and the output from the work permission FF 5 (a logical operation that is turned on when both are ON). As a result, when work permission is set in the work permission FF5 and non-working is set in the operating FF14, the work permission is output. The work permission output is input to the AND circuit 7 and the AND circuit 10 so that the power key 6 and the maintenance panel 9 can be operated.

  Next, the operation of the configuration of FIG. 3 will be described in detail according to the order of the flowchart of FIG.
