The present invention relates to a deburk card for error correction in each module constituting the automated teller machine in the manufacture of the automated teller machine, and more particularly, to be detachably mounted in the expansion slot of the main controller. The present invention relates to a debug card for an automated teller machine that codes and displays errors generated in each module.

In general, the automated teller machine is a device developed to provide a variety of services, including cash and check deposit and withdrawal, unattended, regardless of bank employee's working hours. Financial transactions are made possible through inquiry of password and password, Cash Dispenser with cash withdrawal function as main transaction function, Automated Teller Machine with financial withdrawal function with cash (with check) and financial transaction function There is a kiosk that provides a variety of content, including a variety of fields.

As shown in FIG. 1, the automatic teller machine includes a main controller 10 for controlling various input / output means to control the overall operation of the automated teller machine, and key input means for a user to input data necessary for using information. 11), the bankbook processing means 12 and the card processing means 13 for controlling the entry and withdrawal of the card for identification and transaction account confirmation, the cash withdrawal means 14 for depositing and withdrawing cash requested by the user, the deposit and withdrawal of checks Check and withdrawal means (15), a statement printing module (16) for printing and outputting a transaction result on a statement table, a display means (17) for outputting and providing a request result by a user on a screen, and online communication with a host computer of a financial institution It consists of various control devices and driving devices, such as communication module 18 to perform a financial transaction through. In addition, these various control devices and driving devices are formed in a module unit, and the control devices and driving devices are connected by data communication cables wired around the main controller 10.

In addition, various modules including the main controller 10 are equipped with software for controlling the operation of each module, and the main controller 10 checks the normal operation of each module while controlling the overall operation of each module. When an error occurs in the check process, an error code is generated so that it is possible to check where an error occurs.

However, in the related art, when a defect occurs in a main board constituting the main controller 10 and a defect such as no booting or no screen occurs, simply replace the main board constituting the main controller 10 or replace a memory. Likewise, there was an inconvenience to solve the problem through trial and error of several replacement work.

The present invention has been invented in view of the above circumstances, and is provided in the expansion slot of the main board constituting the main controller in the manufacturing process of the automatic teller machine debug code that can display the abnormal code when the main board is abnormal. It is an object of the invention to provide a debug card for the automated teller machine that can be easily checked and corrected by the production manager when a defect occurs through.

The present invention for realizing the above object,

A debug card main body equipped with an edge connector installed in the expansion slot of the main controller to support specific bus data communication.

A programmable logic device programmable to convert an error code from the main controller board received from the edge connector into a segment drive signal,

And a segment display portion connected to the programmable logic device to display the error code.

In the above, the programmable logic device is further characterized in that the buzzer that sounds an alarm when an error occurs.

In addition, when the error code is displayed on the segment display unit by the programmable logic device, the display state is stopped to maintain the display state of the error code on the display.

Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows a circuit diagram of a debug card according to an embodiment of the present invention, Figure 3 shows an application state diagram of the debug card according to the present invention.

As shown in the accompanying drawings, the debug card body 20 is provided with an edge connector 21 for supporting data communication of a specific bus system. The edge connector 21 may be formed in an arbitrary bus type such as, for example, PCI, ISA, etc., and is mounted on an expansion slot of a main board constituting the main controller to perform data communication.

Programmable logic device 22 is connected to the edge connector 21 in a PCB pattern, a signal that can be displayed as an error code on the segment display device after receiving and calculating the status signal from the main board of the main controller It can be converted to. The programmable logic device 22 preferably uses a programmable element that can be used for other purposes by changing the mounted program as needed.

The segment display unit 24 is connected to the output terminal of the programmable logic device 22 via the segment driver 23. The segment display section 24 is made up of segments capable of displaying digital characters, and displays the error codes output from the programmable logic device 22.

On the other hand, the buzzer 25 is connected to one end of the output of the programmable logic device 22, and when an error occurs, an error code is displayed through the segment display unit 24 and an alarm is sounded so that an administrator can easily recognize the error. I can do it.

The debug card main body 20 configured as described above is mounted on the expansion slot 10A of the main board constituting the main controller 10 of the automatic teller machine. The expansion slot 10A uses a connector of a type that supports the same communication method as the edge connector 21 installed in the debug card body 20.

When the main board 10 is configured to check whether an error occurs in the main board, the debug card main body 20 is mounted in the expansion slot 10A of the main controller 10 before booting the system. After booting the system, the progress signal of the main controller 10 is transmitted in real time through the edge connector 21 mounted in the expansion slot 10A.

Accordingly, the programmable logic device 22 calculates a received signal to determine whether there is an error, and then outputs a signal capable of displaying an error code and displays the signal through the segment display unit 24.

When the error code is displayed in this way, it is preferable to stop the display state so that the administrator can check.

The above error, since the automated teller machine is equipped with a board having a number of functions in the main board constituting the main controller 10, they often affect the booting. Therefore, in order to determine the failure of the main board, it is more accurate to separate the boards, install only the debug card on the main board, and then check the failure.

On the other hand, the non-described power supply unit 26 is for supplying the driving power of the elements driven in the debug card body 20, it is configured to receive after being received from the main controller 10 converted to a predetermined voltage level.

As described above, for the judgment and countermeasures of the failure of the main controller of the automatic teller machine, by using the debug card as described above, by checking the standardized code for the phenomenon of failure, the component providing the direct cause of the failure is immediately identified. The effect is that you can more easily approach the phenomenon and analyze the cause.
