Currency Count Value Verification System {COUNT NUMBER VERIFYING SYSTEM}

The present invention relates to a monitoring system for preventing disputes in financial transactions, and more particularly, to solve disputes caused by paying money by recording a count value at the same time as a video of counting and paying bills with a counter at a bank teller. The present invention relates to a currency count value confirmation system.

In general, video cameras are installed at the window of financial institutions such as banks to continuously record the transaction status of employees and customers to prevent financial accidents and to check when financial accidents occur. In the conventional financial transaction monitoring system, as shown in FIG. 1, the video cameras 10-1 to 10-N installed at the counters use the counters 20-1 to 20-K and customers. In addition to recording the state of the DVR (Digital Video Recorder: 30) and monitor through the monitor 40 or to play the recorded video to monitor the window activity.

Conventional systems for monitoring financial transactions using video recording have a problem in that it is difficult to grasp a monetary count value counted using a counter as an image, making it difficult to check the amount paid to a customer in the event of a dispute.

The present invention has been proposed to solve this problem, and when recording the financial window as a video to record the count value counted using a counter at the same time on-screen display (OSD) method to check the amount of money paid to the customer It is an object of the present invention to provide a system for checking currency count values.

In order to achieve the above object, the system of the present invention includes a video camera for photographing the financial transaction window; A counter for counting money; A communication module for transmitting a count value of the counter; A main block for combining the count value of the counter with the video signal input from the video camera in an on-screen display to output a synthesized video signal; Video recording means for recording a video signal of the main block; And a monitor for displaying an image or a reproduced image during recording of the video recording means.

The communication module includes a counter interface unit for interfacing a communication signal of the counter, a protocol selecting unit for setting an interface method of the counter, an ID setting unit for setting a unique number for identifying the counters, and the main unit. The main block communication unit for communicating with the block, and when receiving the count value of the counter by communicating with the counter according to the interface method set in the protocol selection unit, the count value with the unique number set in the ID setting unit to the predetermined communication protocol It is composed of a MCU to convert and transmit through the main block communication unit.

The main block communicates with each communication module to receive a unique number and count value, the MCU receives a unique number and count value through the communication unit and transmits to the corresponding on-screen display controller, and receives a video signal An on-screen display control unit which separates the synchronization of the input video signal and converts the count value received from the MCU into a character in accordance with the synchronization to synthesize the video signal input in the on-screen display method; Bypass section for bypassing the video output side as it is.

According to the present invention, when counting money using a counter while recording a window of a financial transaction institution as a video, when a dispute related to payment of money occurs at the window by simultaneously recording a unique number, a count value, and a time of the counter. Since the count value of the counter can be accurately confirmed, there is an effect that the dispute can be easily solved.

The technical problems achieved by the present invention and the practice of the present invention will be more clearly understood by the preferred embodiments of the present invention described below. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

The main block 100 for outputting the synthesized video signal by combining the values in an on-screen display method, the DVR 30 for recording the video signal of the main block 100, and a monitor for displaying the recorded or playback video ( 40).

2, the counters 20-1 to 20-K are installed at counters of each financial trading institution to count and display currency during financial transactions of customers and employees, and a separate indicator for the customer is connected and counted. The value can also be checked by the customer. And the interface method of connecting between the counter and the customer indicator may be different for each counter manufacturer, such as RS-232C, RS-422, RS-485, USB, communication module (200-1 ~ 200-K) according to the present invention is According to the interface method of the counters 20-1 to 20-K, the counter value is taken to the corresponding interface method and transferred to the main block 100 by RS-485 communication method. And when a large number of counters (20-1 ~ 20-K) is installed, the communication module (200-1 ~ 200-K) is provided with a dip switch for establishing a unique number (ID) to distinguish each counter. . The video cameras 10-1 to 10-N may shoot one window and one counter, but when shooting two or more windows and two or more counters, the video camera and the counters shot by the video camera are set as a group. It is. For example, when the first video camera 10-1 photographs the first counter 20-1 and the second counter 20-2 simultaneously, the count value of the first counter and the second counter count as the first counter. 1 must be coupled to the video signal of the video camera.

The main block 100 combines the count values of the counters that the video captures with the on-screen display (OSD) method and combines the video signal input from the video cameras 10-1 to 10-N. 30, the DVR 30 records each video signal so that it can be reproduced in case of dispute. The counters 20-1 to 20-K, the video cameras 10-1 to 10-N, the DVR 30, and the monitor 40 are the same as in the conventional configuration, and further description thereof will be omitted.
