Reference numeral 1 denotes a maintenance support device, 2 denotes a host device connected to the maintenance support device 1 via a communication line, and 3a to 3n denote host devices. 2 are a plurality of ATMs to be maintained connected to the ATM. The host device 2 mediates data and control signals between the ATMs 3a to 3n and the maintenance support device 1. From each of the ATMs 3a to 3n, an operation evaluation data group (logging data) including an operation state, an operation amount, and a failure history is sent to the maintenance support device 1. In this embodiment, for the sake of convenience, a case will be described in which, as operation evaluation data, failure display data indicating the device ID of each of the ATMs 3a to 3n, the date of occurrence of the failure, and the event / factor of the failure.

The maintenance support device 1 includes a central processing unit 10 for preparing an inspection instruction for a maintenance person, a parameter input device 20 for inputting and modifying various coefficients and inspection instruction editing parameters, which will be described later, It has an output device 30 and a storage device 40 storing a data file 40a and a parameter file 40b. Parameter input device 20
Is a keyboard or a display device, for example, and the output device 30 is, for example, a printer.

The central processing unit 10 has a communication control unit 11 for acquiring the logging data, automatically classifies the acquired logging data and accumulates the acquired logging data in the data file 40a. A data classification unit 12 for quantifying a fault code for identification with a predetermined weighting coefficient, and an operation evaluation processing unit for performing an operation evaluation of each ATM based on the weighted quantified data and a predetermined evaluation reference value 13 and edits the operation evaluation result in accordance with the inspection instruction edit parameter and outputs the edited result to the output device 30.
And a main control unit 16 for controlling the processing operation of each unit.

When evaluating the failure codes collectively for each mechanism, the data classifying unit 12 replaces a single failure code or together with a single failure code, a card reading mechanism, a bill discrimination mechanism, and a bill transport mechanism. , And a mechanism such as a dispensing port carrying out mechanism. In this case, the classification is performed according to a preset failure code combination rule.

The parameter file 40b includes, in addition to the above-mentioned weighting coefficients, period coefficients, and inspection instruction parameters, inspection items such as replacement part names, lubricating locations, adjustment locations, checking locations, measuring locations, and the like for defective devices. Inspection instruction parameters such as an inspection execution allowable period for the operating device or the defective operating device are stored.

Next, the operation of the maintenance support device 1 having the above configuration will be described with reference to FIGS.

FIG. 2 is a flowchart showing a specific processing procedure. First, the communication control unit 11 is controlled to acquire logging data from each of the ATMs 3a to 3n. Device ID, fault code,
The additional information added to the specific fault code, and the fault information is automatically classified for each fault occurrence date and stored in the data file 40a (S (processing step; the same applies hereinafter) 101). FIG. 3 (a)
Is an example of classification data, and shows a case of a single failure code. At this time, if it is necessary to classify the failure events according to the mechanism, FIG.
As shown in (b), classification is performed by adding a group failure code name and a mechanism name (S103 to S105). Further, at the time of classification, as shown in FIG. 4A, each fault code name is associated with a weighting coefficient. Weighting coefficients W ₁ , W ₂ …
Are determined in advance. The values of these weights are determined by an expert, for example, based on past maintenance records.

After storing the data, the operation evaluation processing unit 13 reads the classification data from the data file 40a and the evaluation reference parameters shown in FIG. 4B from the parameter file 40b, and performs operation evaluation for each ATM (S10).
6, S107).

The details of the operation evaluation processing are as shown in FIG. 5. First, an evaluation period is specified (S201). This period is specified as a period unit determined in FIG. 4B, for example, one month, two months, and so on.

Next, data on the number of fault occurrences for each device ID is extracted from the data file 40a (S202), and the cumulative score for each device ID is obtained by multiplying the data on the number of fault occurrences by a weighting coefficient and a period coefficient (S203). ). And
This accumulated score is compared with the reference score (threshold value) of the period (S205). If the score is less than the reference score, the ATM is determined to be a well-operated device (S206), and the inspection execution period extension instruction data is output. (S207). On the other hand, if the number is equal to or more than the reference point, it is determined that the device is a malfunctioning device (S208), and inspection instruction items and inspection instruction period extraction instruction data necessary for the countermeasure are output (S209).

FIG. 6 shows a specific AT where the device ID is D1.
M is an operation evaluation result when 12 failures with a weighting coefficient of 0.5 occur in one month (period coefficient 1). In this case, the cumulative score is (0.5 × 12 = 6), which is equal to or greater than the reference score (5 points).
It becomes defective operation equipment. In addition, another ATM (device ID: D
In the case of 2), the cumulative score is (1.0 × 5 = 5) as an operation evaluation result when five failures with a weighting coefficient of 1.0 occur in one month (period coefficient 1). It will be working equipment. However, when the evaluation is performed in two months, 12 failures with a weighting coefficient of 1.0 occur, and the reference score (10
Point), the case where the device becomes a defective operation device is illustrated.

Returning to FIG. 2, the data editing unit 14 reads the inspection instruction sheet creation parameters from the parameter file 40b according to the operation evaluation result (S108), and edits the inspection instruction sheet (S109). For example, when the ATM is determined to be a malfunctioning device, a parameter for each fault code shown in FIG. 7A and / or a parameter for each device ID shown in FIG. 7B is read (S108).
The content of the inspection instruction is edited by adding the inspection execution item and its execution period for each fault code (group, single) name.
On the other hand, in the case of a well-operating device, a parameter for extending the inspection execution period is read out and edited.

After that, the editing result is output to the output device 30, where it is printed out, for example, to obtain an inspection instruction (S110). The inspection instruction is passed to the maintenance person, and the inspection is performed according to the instruction.

As described above, according to the maintenance support apparatus 1 of the present embodiment, it is possible to perform a detailed evaluation of the operating state of each of the ATMs 3a to 3n at any time based only on the remotely transmitted logging data. This makes it possible to reliably detect a sign of a failure.

For an ATM determined to be a defective operating device, fault data necessary for the countermeasures, specific work contents, shortening of a permissible execution period, and the like are instructed, and the ATM is determined to be a good operating device. For the ATM, it is possible to output an inspection instruction in accordance with the operating state of each ATM, such as instructing an extension of the conventional inspection execution interval, so that the contents and timing of preventive maintenance inspection by a maintenance person can be output. Optimization and efficiency.

In this embodiment, as the operation evaluation data included in the logging data, the device ID of each of the ATMs 3a to 3n, the date of occurrence of the failure, and the failure display data indicating the event / factor of the failure are used. Although the description has been given of the case where the failure code for specifying the content and the content is quantified by a predetermined weighting coefficient, the present invention performs the operation evaluation by the same processing using, for example, the actual operation time of each part of the ATM. Is also possible.

[0029]

As is apparent from the above description, according to the operation evaluation method of the present invention, it is easy to detect in advance signs of trouble in individual ATMs, and to perform uniform work at fixed time intervals. The effect of preventive maintenance of failures is much higher than the conventional method that has been used. As a result, it is possible to suppress the occurrence of trouble during business hours in the financial institution, and it is possible to solve the conventional problems.

Further, according to the maintenance support apparatus of the present invention, an appropriate inspection item and an inspection execution time are specified for an ATM determined as a defective operation device as a result of the operation evaluation. It is possible to suppress it before it happens. On the other hand, for an ATM determined to be a well-operated device, for example, the inspection execution timing is optimized, so that the non-operation time of the ATM due to the inspection and maintenance work is greatly reduced, and further, unnecessary parts replacement and the associated work amount Is unnecessary, which is advantageous in terms of cost.
