And outputs the count number together when the generated fault information is transmitted to the centralized monitoring device 1b. In the centralized monitoring device 1b, the fault information is printed out (the fault information of ATM 2A, 2B, ... Is investigated) and reset when the fault information stored in the fault information storage file 9a is cleared.

The interface circuit 23 is a centralized monitoring device 1b.
And the connection circuit for communication. The clock unit 3a has a clock function and outputs the time. The transaction mechanism unit 20 uses the ATM 2a (2

The CRT 21 displays a guidance screen, an operation screen, etc. necessary for transaction processing. Touch panel 22 is C
It is mounted on the display surface of the RT21 and the displayed operation screen is input by touch.

Next, each part of the centralized monitoring device 1b will be described.
The CPU 12 controls each unit according to the program stored in the ROM 13. The ROM 13 is a failure control unit (additional means) 8

And a control program for the communication control unit 133.

Although not shown, the fault control unit 8a has an error code name table for converting the received error code into an error name, and based on the fault occurrence notification signal sent from the ATM 2a (2b, ...). The error name is sent to the display control unit 130, the time from the clock unit 7a is added to the recovery signal and the failure information sent at the time of failure recovery, and they are cumulatively stored in the failure information storage file 9a. That is, the device name, the unit name, the command at the time of the occurrence of the primary (secondary and subsequent) failure, and the primary (secondary and subsequent) error name are accumulated and stored.

Although not shown, the display control unit 130 includes operation screen data (device-specific storage failure information calculation display instruction, device-specific unit storage failure information calculation-display instruction, device-specific unit pause time calculation display instruction, and printout. The operation screen is constantly displayed in a predetermined area (for example, the lower end) of the CRT 10b, and the error control unit 8a sends the operation screen. CRT with the error name and the device name and unit name

The print control unit 131 controls the printer unit 11a to print out the fault information read from the fault information storage file 9a. The input control unit 132 sends an input by operating the operation screen displayed on the CRT 10b on the touch panel 15 to the failure control unit 8a.

The communication control unit 133 controls the communication with the ATM 2a (2b, ...) And, regarding the failure, the notification signal of the failure occurrence from the ATM 2a (2b, ...), the recovery signal for the failure recovery and the failure information. To receive.

The RAM 14 is a fault information storage file (second
Memory unit) 9a and a calculation unit (calculation unit) 140. The failure information storage file 9a is, under the control of the failure control unit 8a, the failure information (device name, unit name, failure occurrence time, primary failure and secondary failure information) sent at the time of failure recovery as shown in FIG. Accumulate and store the failure information and transaction count with the recovery time added to the command and error name after the next failure.

The calculation unit 140 calculates a unit-specific pause time (a pause time ratio of a predetermined period, based on a calculation display instruction on the operation screen of the CRT 10b, according to a command from the failure control unit.
Ratio of unit downtime to transaction count, ratio of downtime by fault type (error code), etc.), storage failure information calculation by device (ratio to transaction count for a predetermined period, etc.), or storage failure information calculation by unit by device ( The ratio to the number of transactions in a given period, the ratio of failures per unit to total failures, etc.) are performed.

For example, in the case of calculating the downtime per month, each failure occurrence time and failure recovery for each device and each unit are excluded, except for failures that are not apparatus failures (that is, a command is used to determine whether to stop due to paper money near end or paper near end). The basic data for graphing can be obtained by obtaining the time difference and totaling it.

FIG. 3 (b) is a graph in which the device downtime (difference between failure occurrence time and failure recovery time) per month is calculated and aggregated for each unit, and the results are calculated and aggregated by the operation display instruction to the CRT 10b. Is displayed.

Under the control of the display control unit 130, the CRT 10b displays the units and error names of ATMs 2A, 2B, ... When a failure occurs, and informs them by flashing a part or all of them, and from the operation screen. When the calculation display is instructed, the calculation result calculated by the calculation unit 140 is displayed.

The touch panel 15 is mounted on the display surface of the CRT 10b, controlled by the input control unit 132, and touches the operation screen displayed on the CRT 10b to input an instruction. The clock unit 7a has a clock function and outputs the time.

The interface circuit 16 uses the ATM2A (2B,
...) and a communication connection circuit. It has such a configuration and function, and its operation will be described below with reference to the flowchart of FIG.

First, when transaction processing is performed in the ATM 2A (2B, ...) And some kind of failure occurs, an abnormality is detected by the error sensor and the transaction processing control section 180 and the failure information control section 181 are notified and the apparatus While the operation is "suspended", the error code is read from the error code table 4 and temporarily stored in the failure information file 5b together with the failure occurrence time, and the error code is controlled by the communication control unit 133 to the centralized monitoring device 1b. Send.

The ATM 2A (2B, ...) Has an automatic failure recovery function depending on the type of failure. For example, when a jam of a conveyed bill occurs, the jam bill is slightly returned in the reverse direction and conveyed again in the forward direction. Since it may be restored, this function is effective in the case of a slight banknote jam.

However, when the automatic restoration is not performed, restoration processing by a staff member is required. During such a failure automatic recovery operation, as shown in Fig. 3 (a), a secondary failure or tertiary failure may occur, and if the specified failure automatic recovery operation does not recover, the device will Stop. When a secondary failure or a tertiary failure occurs, the time and error code are temporarily stored in the failure information file 5b.

When the centralized monitoring device 1b receives the error code, the fault controller 8a converts the error code into an error name and sends it to the display controller 130, and the CRT 10b displays the device name (for example, A, B, ...) And the error. The name is displayed and at least a part of the blinking notifies the occurrence of a failure.

Therefore, the clerk recognizes the device name and the error name that has occurred, and performs a recovery process on the corresponding device. When the operation of the equipment is started up by an instruction operation when the fault is recovered by the staff processing, "Handling is stopped" (automatically when the fault is recovered by the fault automatic recovery operation above)
At the same time as the cancellation, the recovery signal and the failure information (primary failure and secondary failure and thereafter) read from the failure information file 5b are transmitted to the centralized monitoring device 1b.

In the centralized monitoring device 1b, the display of the failure notification of the CRT 10b disappears based on the recovery signal, and the received failure information contains the time of the clock unit 7a (= reception time = failure recovery time).
And is cumulatively stored in the failure information storage file 9a.

Thus, when a predetermined period (for example, three months) has passed since the transaction continued, and the failure information investigation time comes, the clerk can operate the touch panel 15 from the operation screen displayed on the CRT 10b of the centralized monitoring device 1b. To instruct the statistical processing of the failure information required by.

Then, the failure control unit 8a reads out the failure information accumulated and stored in the failure information storage file 9a, and the operation unit
Instruct 140 to perform predetermined calculation and display the result on CRT 10b. If necessary, the printer unit 11a prints out the calculation result by operating the operation screen of the printout instruction.

In this way, not only the percentage of the number of faults by ATM 2A, 2B, ..., By unit, by fault type, but also the percentage of downtime due to a fault can be automatically and numerically obtained. As a major failure, it is possible to understand not only the failure that occurs frequently, but also the degree of impact on the device operation of the time of failure (failure that takes time from failure to recovery) due to the failure. It is possible to take remedial measures and contribute to improving the performance of the device. Further, it is possible to easily confirm the effect of the ATM 2A, 2B, ...

Further, the time required for recovery from a failure can be regarded as a maintenance man-hour. From the ratio of the total maintenance man-hour to the total operating time of the device, not only the improvement of the design etc. but also the maintenance system (maintenance technology and maintenance Information can be obtained to help improve personnel.

According to the present invention, the ATM2
This is a method in which a recovery signal and failure information are transmitted from A, 2B, ... And the received time is added to the failure information by the received centralized monitoring device 1b. As an application example, each ATM 2A, 2B ,. A method of adding time and transmitting it to the centralized monitoring device 1b together with the restoration signal is also conceivable.

In the above example, the case of ATMs 2a, 2B, ... Has been described, but the present invention can be applied to not only other automatic transaction devices but also general terminal devices. In the above example,
The case where the fault information accumulated and stored in the fault information storage file 9a of the centralized monitoring device 1b is calculated and output according to the screen operation instruction from the touch panel 15 has been described, but when a predetermined period (for example, 3 months) has passed, It is also possible to use a method of automatically performing printout by performing a predetermined calculation.

Further, in the above example, the case where the counter 190 counts the number of transactions has been described. However, since the cumulative number of transaction banknotes (deposited number, withdrawn number) is actually counted, the transaction banknotes are counted. Using the count value of the number of coins, for example, a method of comparing a failure such as a banknote jam as an occurrence rate with respect to the number of banknotes in transaction may be used. Alternatively, a method may be used in which the actual working time of the device is cumulatively counted to obtain the failure rate with respect to the actual working time.

Further, in the above example, the case where the ATMs 2a, 2B, ... Used in the bank etc. are centrally monitored has been described, but the method according to the present invention is also applied to the continuous test such as the shipping test of the device. can do.

[0066]

As described above, according to the present invention, the failure information is collected in the monitoring device, and can be classified into terminal devices, units, etc., and output when necessary. Since the time of failure occurrence and the time of recovery are added, the time required for failure recovery can be known, and it is possible to appropriately judge not only the failure frequency but also the time taken for recovery, in order to judge the critical failure. Therefore, it is possible to contribute to the improvement of the reliability of the terminal device.

Furthermore, it is possible to easily confirm the effect of taking measures against troubles, and it is also possible to use it for quality confirmation in a continuous test before shipping the terminal device. Further, it is possible to obtain information that is useful not only for improving the design and the like, but also for improving the maintenance system such as the maintenance technique and the maintenance personnel from the ratio of the maintenance man-hour and the operation time of the device. This has the effect.
