  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 shows station equipment when the station equipment is an automatic ticket gate (corresponding to the ticket gate of the present invention) G and an automatic ticket vending machine (corresponding to the ticket issuing machine of the present invention) a. It is a schematic block diagram of a monitoring apparatus.

  The automatic ticket gate G has a CPU 2 that performs predetermined arithmetic processing for entry and exit based on data stored in a memory 1 including a known ECC memory. A ticket gate processing unit 4 and a display unit 5 are connected to the CPU 2 via an I / O unit 3. The ticket gate processing unit 4 includes a card handler and a reader / writer for reading data recorded on a boarding ticket or a non-contact ticket and writing new data, and a door driver for controlling the opening and closing of the door. It is configured to include. The display unit 5 is configured to include a display screen 5a as shown in FIG. 2, and when the automatic ticket gate G is in the entrance / exit processing mode, the user (passenger) has a predetermined content in characters. In the maintenance inspection of the automatic ticket gate G, predetermined contents can be displayed to maintenance personnel.

  The communication control unit 6 connected to the I / O unit 3 connects the automatic ticket gate G to the monitoring panel 7 installed in the attendant corner of the ticket gate corresponding to the host device of the automatic ticket gate G via the communication line L1. To connect. Although not shown, other automatic ticket gates are connected to the monitoring panel 7 via a communication line L1.

  The monitoring board 7 is configured with a CPU (not shown) as the center, similarly to a known monitoring board, and can monitor the operating state of the automatic ticket gate G and an automatic ticket gate (not shown) via a display screen. In addition, a specific automatic ticket gate can be remotely subjected to a predetermined process such as a reset process if necessary.

  The automatic ticket vending machine a has a CPU 11 that performs a predetermined calculation process for issuing a ticket based on data stored in a memory 10 including a known ECC memory. The CPU 11 is connected with a billing unit 13 and a display unit 14 via an I / O unit 12. The above-mentioned ticket processing unit 13 prints a predetermined content on an input unit consisting of an account button group, a ticket to be issued, and writes magnetic data of a predetermined content, and money inserted into the ticket issuing unit and the automatic ticket vending machine a. Is included, including a money processing unit that discharges change when necessary. In addition to the display screen, the display unit 14 displays the amount of money inserted into the automatic ticket vending machine a in addition to the display screen, and when the automatic vending machine a is set to the maintenance / inspection mode, its maintenance is performed. It is configured to include a display screen that displays predetermined contents to personnel.

  The communication control unit 15 connected to the I / O unit 12 turns the automatic ticket vending machine a into a so-called station system 20 installed in a station office where the automatic ticket vending machine a is a host device of the automatic ticket vending machine a. This is for connection via the communication line L2.

  The station system 20 is mainly composed of a microcomputer, and is also connected to the monitoring panel 7 via a communication line L2. This station system 20 is used for counting the number of entrances and exits of the automatic ticket gate G, sales of the automatic ticket gate G (sales when the SF card is used in the automatic ticket gate G), sales of the automatic ticket machine a, etc. It is configured so that it can be aggregated. The station system 20 is also connected to other ticketing machines such as an automatic settlement machine, an automatic commuter pass vending machine, or a card vending machine (not shown) via the communication line L2, and is installed at the station. It is configured so that the entire aggregation process can be performed.

  The monitoring control operation when the station service device is the automatic ticket gate G will be described below with reference to the flowcharts of FIGS. 3 (a) and 3 (b).

  Now, it is assumed that the automatic ticket gate G is turned on in accordance with the first train and the automatic ticket gate G is set in a state in which entry / exit processing is possible (Yes in Step 100; hereinafter, step is referred to as “S”). .

  While the automatic ticket gate G can be entered and exited, that is, while the automatic ticket gate G is set to the entrance / exit processing mode, a ticket (a ticket made up of a magnetic ticket or a ticket made up of a non-contact ticket) A predetermined entry / exit process using the above is performed (S102). If a minor error (1 bit error in the example shown in the figure) occurs in the meantime, predetermined error data such as the address, data content, date and time of occurrence is stored in a predetermined storage unit of the memory 1. (S106).

  Even if a minor error as described above occurs in the memory 1 of the automatic ticket gate G, since the memory 1 is composed of an ECC memory, the error is corrected and normal entry / exit processing is performed. Such collection and storage of error data is continued while the automatic ticket gate G is operating (No in S108). The error data can be stored in the monitor panel 7 or the station system 20 memory. Although not shown in the flowchart of FIG. 3A, when a serious error that cannot be corrected by the ECC memory, for example, a 2-bit error occurs, the automatic ticket gate G cannot perform normal entry / exit processing. The operation is stopped, the automatic ticket gate G is placed in a system down state, and an emergency restoration work is performed by maintenance personnel.

  The error data collection and storage described above is an example of the automatic ticket gate G, but is similarly performed in other automatic ticket gates. Similarly, error data is collected and stored in the automatic ticket vending machine a and other ticketing machines not shown.

  FIG. 3B is a flowchart at the time of periodic inspection of the automatic ticket gate G. Now, when the time for periodic inspection of the automatic ticket gate G comes, the automatic ticket gate G is set to the maintenance inspection mode via the clerk operation unit (Yes in S200, S202). When the inspection mode is set to the memory state in the inspection (Yes in S204), the display screen 5a displays the contents based on the error data stored in the memory 1 by the predetermined software (S206). . That is, if error data is stored in the memory 1, the contents are displayed, and the maintenance staff determines whether or not the memory 1 needs to be replaced based on the displayed contents, and if it is determined that the replacement is necessary The memory is exchanged (Yes at S208, S210). Of course, if no error data is stored in the memory 1 in the memory state check mode, the memory normal operation is displayed, and the memory check operation is terminated (omitted in the flowchart of FIG. 3B).

  The criterion for determining whether or not to replace the memory 1 can be arbitrarily determined, but it is also possible to replace the memory when an error occurs even once. Further, the memory can be replaced when the number of errors reaches a predetermined number (for example, 3 times or more), and further, it can be performed based on the frequency of occurrence of the error. In any case, if the error occurrence is left unattended, a severe error occurrence may occur in the near future, and it can be known that there is a high possibility that the system will go down. In other words, it is considered that a minor error has occurred before the system of the automatic ticket gate G is down due to a severe error. Therefore, it is possible to predict the occurrence of a severe error from the minor error and replace the memory. Done.

  When the inspection of other inspection items other than the memory inspection is also completed, the automatic ticket gate G is inspected and set to the entrance / exit processing mode (No in S204, S205, Yes in S212). The above-described periodic inspection is an example of the automatic ticket gate G, but an automatic ticket gate (not shown) is also checked in the same manner, and the memory is exchanged as necessary. In addition, the automatic ticket vending machine a and other ticketing machines (not shown) are also inspected, and the memory is exchanged as necessary.

  In the above example, the error data is displayed on the display screen provided in the station service equipment such as the automatic ticket gate G at the time of periodic inspection. It may be displayed on the display screen. Furthermore, when a data error occurs in the automatic ticket vending machine a and other ticketing machines not shown, or in the automatic ticket vending machine a and other ticketing machines (not shown), the number is specified and the display screen of the monitoring panel 7 or the station system 20 is displayed. You may make it possible to call attention by displaying it. The output in this case may be performed when the data error reaches a predetermined number of times (for example, twice or more) or when a predetermined occurrence frequency is reached. However, since the occurrence of the above-mentioned minor data error is a very rare phenomenon, it is preferable to output it every time it is generated to call attention.

It is a schematic block diagram of the station service equipment monitoring apparatus which concerns on one embodiment of this invention. It is a display example of a display screen. It is a flowchart which shows control operation.
