Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a fault determination method for determining a fault in a device that has a banknote identification function and that identifies a plurality of banknotes one by one to deposit cash. [Prior art] Conventionally, devices for depositing cash, etc. have a banknote identification function, and perform tasks such as determining the denomination of deposited banknotes and determining authenticity. Since the banknotes in circulation are often manipulated, identification check errors such as authenticity verification occur continuously.

There are two types of identification check errors: one is due to the insertion of a defective banknote, and the other is due to a failure when the identification function of the device does not work properly. The disadvantage is that it is not possible to distinguish whether the device has been inserted or the device is malfunctioning. [Object of the invention] The present invention has been made to solve the above-mentioned drawbacks,
The purpose is to quickly determine whether a defective banknote has been inserted or whether there is a malfunction in the device.

[Structure of the invention]

In order to achieve the above-mentioned object, the present invention provides that when the number of bills V that are consecutively determined to be errors by the bill recognition section is less than the set number, the bill is determined to be defective and the entire device is removed. If the number of consecutively determined errors reaches the set number, it is considered a bad transaction, and the number of consecutive bad transactions is counted and the consecutive bad transactions are counted. If the number of transactions is less than a set number within a preset period, it is determined that the banknote is defective, and when the number of defective transactions reaches a set number, it is determined that the device is malfunctioning.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a flowchart showing an embodiment of the failure determination method according to the present invention. This shows the stage of detecting whether or not an identification check error has occurred in each banknote as a result of performing authenticity appraisal, denomination discrimination, etc. through the banknote recognition unit. The defective banknote counter indicates a step of counting the consecutive number of detected error banknotes and detecting whether the set number 711 has been reached.

"Is the bad transaction counter = +L2?" is a stage to know the relationship between the operating state of the device in the transaction currently being executed and the operating state of the device in the transaction before this transaction.If the number of bad transactions is less than L2, If it is 7L2, it is assumed that the identification check error occurred due to a defective banknote, and if it is 7L2, it is due to a failure of the device! Each process is performed assuming that an identification check error has occurred.

Finally, if the identification check error reaches the set number n1 for each transaction, it is possible that the device is malfunctioning, and at the stage of "Bad transaction counter + 1", it is determined that the error occurs within a certain period of time. It is calculated by dividing the frequency of occurrence of .

Therefore, if the inserted banknote is not defective and the device is operating normally, the system can pass through ``Bill suction'' - ``Is it an identification check error?'' ``Defective banknote counter reset'' - ``Normal processing.'' If there are no unprocessed banknotes, the process goes through route a and executes ``bill suction'' again, and when there are no unprocessed banknotes, the process goes through route b to ``go to the next transaction.''

Also, "inhalation of banknotes" = "identification check error" - "
Defective banknote counter +1" - "Defective banknote counter = n1.
J-r Unprocessed banknotes present - ``Proceed to next transaction'' step c) is a stage in which the device is operating normally and it is determined that there was a defective banknote during the transaction.

Furthermore, at the stage where the device is operating normally and the inserted banknote is judged to be defective, "Bill suction" - 0tlt separate check error? - "Defective banknote counter + 1j-r Defective banknote counter n1J -r Bad transaction counter +1”
- You can also get route d of "Defective Transaction Counter-2J-r Defective Banknote Counter Reset". That is, if the number of consecutive banknotes with identification check errors is n1 and the number of defective transactions is less than ■ times within a preset period, it is determined that the banknotes are defective.

If the inserted banknote is not a defective banknote and the device is malfunctioning, "Bill suction" - "Is it an identification check error?"
"Bad banknote counter + 1" - "Bad banknote counter = y
bI J-r Failure Handling' Route e is taken. That is, when the number of consecutive coins with an identification check error is n1 and the number of defective transactions reaches n2 within a preset period, it is determined that the device is malfunctioning.

FIG. 2 is a block diagram showing the main components of an embodiment of the failure determination method according to the present invention. In FIG. This part has a bill insertion slot and a function to display whether it is in operation or not.

Reference numeral 2 denotes a banknote identification unit, which has sensors required for conveyance of banknotes, authenticity appraisal, denomination determination, etc., and the banknotes inserted into the customer service unit 1 pass through a separation mechanism unit, a conveyance unit, etc. (not shown). By passing through the banknote identification section 2, information for identification check is transferred to the banknote identification control section 3.

The banknote identification control unit 3 is composed of a logic circuit such as an amplifier for the above-mentioned sensors and a micro-combiner, and receives identification check information from the banknote identification unit 2 to determine the authenticity and denomination of the banknote. Identification etc. are carried out sequentially for each banknote,
If the bill is normal, the defective bill counter 4 is reset; if the bill has a check error, the defective bill counter 4 is counted and the result of the identification check is transmitted to the main control section 5. When the defective banknote counter 4 reaches the set number of banknotes 1, it is transmitted to the main control section 5.

The main control section 5 is composed of a logic circuit such as a microcomputer, and controls the bill recognition section 2 via the customer service section 1 and the bill recognition control section 3, as well as controlling each part of the device. The information of the defective banknote counter 4 coming from the banknote identification control unit 3 is managed, and if the value of the defective banknote counter 4 is less than the set number of banknotes 7L1, the banknote is determined to be defective, and when the value of the defective banknote counter 4 reaches the set number of banknotes anx. counts the defective transaction counter 4, and when the defective transaction counter 4 reaches the set number n2 within a preset period, it instructs the customer service department 1 to display an inactive status as a failure of the device and performs trouble handling.

In this embodiment, the banknote identification control section 3 and the main control section 5 are provided with separate logic circuits such as microcomputers, but they may be integrated into one depending on the configuration of the device. be.

Therefore, one embodiment of the failure determination method according to the present invention shown in FIG. 1 can be realized using the configuration example shown in FIG. 2 described above.

〔Effect of the invention〕

As described above, according to the failure determination method according to the present invention, if the number of banknotes that are consecutively determined to be in error by the banknote recognition unit is less than the set number, the banknotes are determined to be defective and the entire device is shut down. is prepared for the next transaction, and if the number of consecutively judged errors reaches the set number, it is considered a bad transaction, the number of bad transactions is counted, and the number of bad transactions is within a preset period. If the number of defective transactions is less than the set number of times, the banknote is determined to be defective, and if the number of defective transactions reaches the set number within a preset period, it is determined that the device is malfunctioning, so if an identification check error occurs, the device This has a significant effect in that it can be quickly determined whether there is a defect in the banknote inserted into the machine or a failure in the device.

Further, since the present invention is a failure determination method using a banknote identification function, it has the advantage that it can be used in various cash processing devices having a banknote recognition function.
