경화 판별장치 및 방법Curing Discrimination Device and Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1도는 본 발명의 경화 판별장치의 회로도, 제3도의 (가) - (라) 는 경화를 투입하였을 경우에 제1도의 각부의 파형도, 제5도의 (가) - (나) 는 본 발명의 경화 판별 방법에 의한 마이콤의 동작과정을 보인 신호 흐름도.1 is a circuit diagram of the coin discrimination apparatus of the present invention, (a) to (d) of FIG. 3 is a waveform diagram of each part of FIG. 1 when a coin is added, and (a) to (b) of FIG. Signal flow chart showing the operation of the microcomputer by the method of hardening determination.

Claims (3)

마이콤을 이용하여 투입된 경화의 종류를 판별하는 경화 판별 장치에 있어서, 투입된 경화의 재질에 따라 두 개의 이차코일로 유도되는 신호의 위상차를 변화시키는 트랜스와, 상기 두 개의 이차코일로 유도된 신호의 위상차를 코드신호로 변환하는 코드 변환부와, 상기 코드 변환부로부터 입력되는 코드신호와 피롬에 저장된 기본코드를 비교하여 투입된 경화의 종류를 판별하는 마이콤과, 경화의 수납을 검출하는 경화수납 검출부로 구성함을 특징으로 하는 경화 판별 장치.In the coin discrimination apparatus for discriminating the type of coin hardened by using a microcomputer, a phase shift between a transformer for changing the phase difference of a signal induced by two secondary coils according to the material of the coin hardened, and a phase difference of the signal induced by the two secondary coils A code conversion unit for converting a signal into a code signal, a microcomputer for determining the type of coin added by comparing the code signal input from the code converter with a basic code stored in a pyrom, and a coin storage detection unit for detecting the storage of the coin. Curing determination device, characterized in that. 제 1항에 있어서, 코드 변환부는 두 개의 이차코일로 유도된 신호로 위상차 검출신호를 출력함과 아울러 위상차 검출신호의 출력이 완료되는 시점에서 마이콤으로 인터럽트 요청신호를 입력시키는 위상차 검출부와, 위상차 검출신호에 따라 클럭신호를 선택 출력하는 멀티플렉서와, 상기 멀티플렉서가 출력한 클럭신호를 카운트하여 상기 마이콤에 입력시키는 카운터로 구성함을 특징으로 하는 경화 판별장치.The phase difference detection unit of claim 1, wherein the code converter outputs a phase difference detection signal as a signal induced by two secondary coils, and inputs an interrupt request signal to the microcomputer when the output of the phase difference detection signal is completed; And a counter for counting and outputting a clock signal output by the multiplexer to the microcomputer. 마이콤을 이용하여 투입된 경화의 종류를 판별하는 경화 판별 방법에 투입된 경화의 재질에 따라 두 신호의 위상을 변화시키고, 그 두 신호의 위상차를 검출하며, 위상차의 시간동안 클럭 신호를 카운트하여 경화의 코드신호를 만들며, 그 코드신호와 기억되어 있는 코드 신호를 비교하여 투입된 경화의 종류를 판별함을 특징으로 하는 경화 판별방법.In the coin determination method to determine the type of coin added using a microcomputer, the phase of the two signals is changed according to the material of the coin added, the phase difference between the two signals is detected, and the clock signal is counted for the time of the phase difference. A coin discrimination method, characterized in that for generating a signal and comparing the code signal with the stored code signal to determine the type of coin added. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
