Abstract

PURPOSE:To easily find out the cause of noncoincidence in the tabulation of cash by providing a means to log transaction data in a prescribed period, faulty data, and retry data when a fault occurs, and a control means to perform the diagnosis of the occurrence of the fault with a prescribed diagnosing means. CONSTITUTION:The payment transaction of the cash is performed by inserting a card to a magnetic card handling mechanism MCU 6 and performing key input from an operating part 7 with a user. The transaction data, that is, a transaction date, a transactor, transaction amount, and the faulty data when the fault occurs, that is, a fault generating part and generating time are logged in an external storage. When a trouble occurs in the tabulation of the cash, developmental status is inputted to an automatic transaction device, and the cause is estimated with the device, and when a card error occurs, the data is collated with log data, thereby, it is estimated in which, a medium or the device, the trouble occurs, and also, when an automatic operation in a holiday is performed, the feasibility of the operation is judged with the device itself.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic teller machine, and particularly to an automatic machine with a fault diagnosis function.

(Prior art) As disclosed in Japanese Patent Laid-Open No. 61-276095, the above-mentioned conventional technology adds temporal information to the fault code and logs it, and when necessary, maintenance personnel can perform the following operations:
It is now possible to check for failures by printing them on a journal, etc.

(Problems to be Solved by the Invention) In the above conventional technology, raw fault data is output from the automatic teller machine, and information such as the occurrence location, cause, countermeasures, required part number, required equipment, etc. is sent to the on-site staff. Do you have an interview or
The problem was that the actual situation could not be ascertained unless one went to the site and grasped the situation firsthand.

The present invention enables the device itself to trace the thought process of maintenance experts, and from the fault data, considers how the device itself should respond to the fault, prints it on a CRT, slip, or line, and outputs it to quickly The purpose is to provide countermeasures for obstacles. In particular, it analyzes when there is a discrepancy in the tally and when there is a card error, and it also determines whether or not holiday operation is possible during automatic operation.

(Means for solving the problem) The above purpose is to provide a device for logging transaction data, failure data, and retry data when a failure occurs during a predetermined period, and a control means for diagnosing the occurrence of a failure using a predetermined diagnostic procedure. This is achieved by an automated cash transaction machine equipped with a fault diagnosis function.

(Function) With the above configuration, when a cash aggregation trouble occurs, the occurrence situation is input into the automatic transaction H field and the device estimates the cause.
When a card error occurs, it is compared with logging data to estimate whether the problem is with the medium or the device, and when implementing holiday operation by automatic operation, the device itself determines whether the operation is possible.

(Example) An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of the hardware of an automatic machine according to the present invention, in which a customer inserts a card into an MCU (magnetic card handling mechanism) 6 and manually presses a key from an operating section 7 to receive cash. A payment transaction is performed. Transaction data, ie, transaction date, transaction person, transaction amount, and failure data at the time of failure, ie, failure occurrence location and occurrence time, are cogged into external storage.

Below, we will describe how to determine the cause of discrepancy in totals using logging data, determine whether the cause of the card error is on the medium side or the device side, and determine whether operation is possible during holidays.

(a) Cash tally discrepancy failure When a cash discrepancy occurs, enter the details of the discrepancy.

Example 1: Discrepancy between center tally and terminal tally Example 2: Mismatch between banknotes in the cassette and terminal tally Next, from the CRT screen, information on when the discrepancy was discovered and at what transaction stage the discrepancy occurred. input. FIG. 2 shows an example of an error menu displayed on the CR7 screen.

FIG. 3 is a schematic diagram showing the timing of aggregation at the center and the aggregation with the automatic terminal machine, and shows the timing of the aggregation at the center and the automatic terminal machine. - In a transaction, after sending and receiving inquiries and response messages, feeding out banknotes, printing slips, reading cards, etc. In a system where the equipment side performs the operations of , and after the operation is completed, the operation reports the completion to the center. ! The tally on the side of the center that receives the completion report from the site shall be updated. If a response to the confirmation from the center is not received due to a failure, the center side will have updated the tally, but the H room side will not have updated it, and a discrepancy will occur.

In actual systems, the aggregation timing and the retry method in the event of a failure are devised to avoid discrepancies, but discrepancies may occur depending on the failure situation, and the present invention is effective in such cases. be.

FIG. 4 describes the possibility of mismatch between the banknotes in the cassette and the total. When operating for remote location monitoring, manual confirmation is hardly expected, so if a failure occurs during a transaction and the system is restarted without checking inside the device, in rare cases the sensor may not be detected. It is expected that the banknotes will be tied up in the area. If the system is operated as it is, a problem will arise if the banknotes that have been detained due to a problem during a transaction are released simultaneously, resulting in excessive release. In such a case, there was a possibility that there was a media remaining in the device when a failure occurred, or there was a history of the door being opened, a faulty unit set, a faulty cassette, a power cut, etc., which were subsequently checked manually, or the recovery process was performed without taking any countermeasures. The system traces the start-up process and points out transactions that are likely to result in aggregation discrepancies and events that are obstacles.

FIG. 5 is a flow diagram illustrating an embodiment of the diagnostic procedure, in which the apparatus is
Based on the discrepancy status data input from the RT screen, a factor considered to have caused the discrepancy is searched and displayed from among the fault data since the matching totals.

(b) Card error When a card read error or write error occurs, check the frequency of past occurrences, the degree of consecutive occurrences, etc. FIG. 6 shows the occurrence of errors within a certain period. Various patterns of failures occur, such as Type A, which is generally low in incidence, Type B, which increases rapidly after a certain day, and Type C, which conversely decreases. For example, in the case of type B, it is possible that an abnormality has occurred in the hardware since the day when the number suddenly increases. On the contrary, it is thought that maintenance was performed on the C type on the day when the number suddenly decreased.

As shown in Figure 7, the frequency of occurrence in the past month and week,
Check to see if there is a sudden increase in singular days and if they have occurred consecutively in the previous multi-take, and if there is a frequency hole or singular day, or if it has occurred consecutively in the previous multi-taker, Suppose that it is determined that it is a hardware error and the device goes down. In other cases, it is assumed that there is an error in the card medium, and the device waits for the next transaction without shutting down.

In addition, when checking for the last quantity taken, in order to exclude cases where the same card is inserted, it is necessary to wait at least 5 minutes or more during the transaction at least once. 8th
The diagram shows this. For example, there is a gap of 6 minutes between transaction 2 and transaction 3, so if the interval between transaction 1 and transaction 3 is less than 5 minutes, if it occurs 4 times in a row, you will not be seen. .

The above has described how to respond when a failure occurs, and the determination of whether or not the system can be operated during holidays will be described below with reference to FIG. 9. Data on failures that occur during operation is logged, and the failure down rate (number of downtimes/number of transactions x 100) and card error rate (number of errors occurring/number of transactions x 100) for a certain period in the past, for example, one week, are calculated.

If it is a holiday when the power is turned on, the failure down rate and card error rate are checked, and if the failure rate and card error rate are higher than the specified values, it is reported to the center that operation is not possible. When the system is determined to be inoperable, it is suspended and remains in that state until it receives operational instructions from the center. If it is determined to be operational, it will begin operation on the same day.

This feature is particularly useful for devices that operate automatically and without human intervention.

(Effects of the Invention) By implementing the present invention, when a cash tally does not match, it is possible to output the factors that cause the discrepancy and facilitate investigation of the cause. , the device can determine whether the cause is on the hardware side, and when the device is operated automatically and is operated on holidays, it can judge whether or not the device can be operated based on the degree of past failures, and if the device cannot be operated. By not operating
It is possible to avoid confusion caused by failures during operation.
