As shown, the financial automation device for checking the failure of the paper type recognition using a magnet according to an embodiment of the present invention, a plurality of cash cassettes (130, 140, 150, 160) is implemented in the form of a rectangular box of a size that can hold bills And a magnetic sensor unit 131 installed on one side of the cash cassettes 130, 140, 150, and 160, and configured by a plurality of magnetic sensors that sense the magnetic force generated from the magnet unit 132 and generate an identification signal for recognizing the paper type of the bill. And a magnet part 132 configured to have the same number as the number of the magnetic sensors and installed side by side to face each magnetic sensor so that the magnetic sensor generated by the magnet is sensed by the magnetic sensor part, and the magnetic sensor part ( Receiving the identification signal for the winding species generated in 131, and first determine whether the magnetic sensor failure, and Generating a predetermined binary code from a separate signal, extracting the winding type information of the pre-stored banknotes from the memory unit 120 below, the winding type recognition unit 110 for grasping the winding type of the banknotes, of the banknotes corresponding to the binary code It is characterized in that it comprises a memory unit 120 that is received and stored in advance the handpiece information from the administrator.

Cash cassettes (130, 140, 150, 160) is a bill storage device implemented in the form of a cuboid box to store the bills required for financial transactions of financial automation devices, and can store one or more bills of the same kind and are provided in a plurality of financial automation devices. do.

The magnetic sensor unit 131 is installed inside the main body so as to face a magnet of the magnet unit 132 provided on one side of the rectangular parallelepiped cash cassettes 130, 140, 150, and 160, and the number of magnetic sensors constituting the magnetic sensor unit is the magnet unit. Corresponds to the maximum value of the number of magnets. When magnetism occurs in a magnet designated by the magnet unit 132 so that a binary code identical to a binary code of a paper currency stored in the memory unit 120 may be generated, the magnetic sensors generate an identification signal by detecting the magnetism. To 110). The identification signal transmitted from each magnetic sensor is transmitted to the scoop recognition unit 110 to generate a binary code. When the magnetic signal is detected by the magnetic sensor, the identification signal is transmitted to the scoop recognition unit 110. The scoop type recognition unit 110 generates a binary code "1" from the identification signal, and transmits the identification signal generated when the magnetic sensor is not detected to the scoop type recognition unit 110, the identification signal From the winding type recognition unit 110 generates a binary code of "0". In the present embodiment, the magnetic sensor unit 131 is composed of four magnetic sensors for identifying the winding of the bill and one magnetic sensor for detecting the failure. The four magnetic sensors for identifying the paper types of the bills can recognize a total of 2 ⁴ types, that is, 16 types of bills. For example, when the third magnetic sensor of the sensor unit installed in the first cash cassette 130 and the identification signal generated by the magnetism generated only in the fourth magnetic sensor are transmitted to the scoop recognition unit 110, the scoop recognition unit 110 ) Generates a binary code of "0011" from the identification signal, thereby giving a banknote identification binary code of "0011" to the bill stored in the first cash cassette.

The magnet unit 132 is provided with the same number as the magnetic sensor of the magnetic sensor unit, including a normal magnet and one check magnet 133, in this embodiment four magnets for identifying the paper type of the bill, and detecting whether there is a failure It consists of one check magnet 133 for. Magnetism is generated only in a magnet at a predetermined position so as to correspond to a binary code for each kind of banknote previously stored in the memory unit 120, so that a corresponding magnetic sensor detects it and generates an identification signal. The magnet is preferably composed of a permanent magnet or an electromagnet.

The check magnet 133 is a member used to detect a failure of the magnetic sensor to prevent a financial accident that may occur in a financial automation device, and is disposed at the end of the arrangement of general magnets in the magnet part 132. Magnetic sensors can be easily worn due to frequent detachment or magnetism detection of magnets, and magnetic fields are weakened over time when using permanent magnets as magnets that generate magnetism in magnetic sensors. , In the case of electromagnets, an operation error may occur, and the magnetic sensor malfunctions due to frequent exposure of the cash cassettes 130, 140, 150, and 160 where the magnetic sensors are installed by the manager to the outside of the financial automation device. May result. For example, if the magnet of the magnet disposed at the position where the magnet should occur is weakened and cannot be detected by the magnetic sensor, the wrong identification signal is transmitted to the winding type recognition unit 110 and stored in the memory unit 120. The result is different from the first kind-specific binary code given to the bills of the corresponding cash cassettes, which may cause an accident in which the bills of the customer of the financial automation device are not released.

The check magnet 133 is used to detect a failure of the magnetic sensor, and when such a problem occurs, the check magnet 133 may be transmitted to the manager to prevent a financial accident.

The structure and operation of the check magnet 133 having the above function will be described in detail with reference to FIGS. 2 and 3 to be described later.

The paper type recognition unit 110 generates a binary code from the identification signal received from the magnetic sensor unit installed in the specific cash cassette, and extracts the paper type information of the bill corresponding to the binary code previously stored in the memory unit 120. Recognize about the paper currency of the bill included in the cash cassette. In addition, before receiving an identification signal from the magnetic sensor unit, it is determined in advance whether the number of magnetic sensors that detects the magnetic force, which is a criterion for determining whether there is an error, is even or odd. If so, a fault signal is generated for the failing cash cassette.

The memory unit 120 stores the book type information of the paper money stored in the financial automation device and a binary code corresponding to each book type information, and provides the information to the book type recognition unit 110. The binary code may be stored in advance by an administrator.

2 is a block diagram illustrating a state in which magnetism occurs in a magnet part including a check magnet according to an exemplary embodiment of the present invention.

As shown, FIG. 2 shows the operation of the magnet unit 132 installed in a total of four cash cassettes 130, 140, 150, and 160, each of which holds banknotes of different volumes. The number of magnets generating magnetism as a criterion for determining a failure in the magnet part 132 including a magnet in which magnetism is generated at different positions and numbers for each winding type, and a check magnet 133 for checking for failure. When the sum is set to an even number, if the number of magnets generating magnetism indicating an odd number is odd, the magnet is generated in the check magnet 133 so that the total number of magnets generating magnetism is an even number, and the magnet representing the winding type. When the number of generated magnets is even, the magnet is not generated in the check magnet 133 so that the total number of magnets in which the magnets are generated is even. At this time, it should be confirmed that the number of magnetic sensors that detect magnetism is an even number through the identification signal transmitted from the magnetic sensor unit 131 composed of magnetic sensors corresponding to the magnets of the magnet unit 132 to the winding type recognition unit 110. It is determined that the recognition of the swelling is performed normally, and there is an obstacle in the process of the recognition of the scoop of the magnetic sensor having an odd number of magnetic sensors.

Binary codes generated from the identification signal transmitted from the magnetic sensor unit of the first cash cassette 130 having the 100,000 won bill and the third cash cassette 150 having the 5,000 won bill to the paper type recognition unit 110 are each ". 11110 "and" 00110 ", since the number of magnetic sensors that detect the magnetism from the number of four and two to form an even number, respectively, it is not necessary to generate the magnetism of the check magnet 133 in the magnet portion, but to store the full circle The binary code generated from the identification signal transmitted from the magnetic sensor unit 131 of the second cash cassette 140 and the fourth cash cassette 160 holding the thousand won ticket to the paper type recognition unit 110 is "01110", respectively. Since the number of magnetic sensors that detect magnetism with and "00010" forms an odd number of three and one, respectively, the magnetic force of the check magnet 133 disposed at the end of the magnet is generated and the corresponding magnetic sensor generates the odd number. By detecting, by generating a binary code of "01111" and "00011", respectively, the number of magnetic sensors that detect the magnetism is configured to be an even number. For example, when the second magnet of the second cash cassette 140 fails and no magnetism is generated, the binary code generated from the identification signal from the identification signal becomes “00111” and becomes odd. 2 Detects the failure of the cash cassette and generates a failure occurrence signal. As another example, when the third magnet of the second cash cassette 140, in which magnetism should be generated, is not installed due to a mistake of the financial automation device manager, the binary code generated by the denomination recognition unit from the identification signal becomes “01011”. Since the odd number recognition unit detects an error of the second cash cassette, an error generation signal is generated.

As shown, in the first step (S210) of the failure detection method of the magnet unit and the magnetic sensor unit using the check magnet 133, the identification signal generated by sensing the magnetic force from a plurality of magnets corresponding to the magnetic sensor unit is wound. Pass it to the recognition unit. In a second step (S220), the winding type recognition unit generates a binary code from the identification signal of the first step (S210), extracts the number of magnetic sensors that detect the magnetic and determines whether the sum is an even or odd number. In a third step (S230), based on whether the odd number of the number of magnetic sensors that detect the magnetic, which is a criterion for determining whether or not the failure is determined in advance, whether or not the odd number is determined from the result of the second step (S220) do. For example, if the criterion for determining whether a disorder is an even number is determined that the sum of the number of magnetic sensors that detects magnetic is an even number, it is determined that an error has occurred. In a fourth step S240, as a result of the determination in the third step S230, when a failure occurs, a failure occurrence signal is generated in a corresponding cash cassette, and in a normal state, recognizing a denomination using the binary code. Will proceed.
