Abstract

본 발명은 전동차용 ATS/ATC 장치에 관한 것으로, 특히 중앙(지령실)에서 송신되어 오는 신호 즉 지령신호를 정확하에 수신토록 개선된 회로에 관한 것으로서, 종래에는 L-C 회로로 구성된 필터 및 디코더 회로를 사용하여 데이타 전달이상에 에러가 발생할 우려가 있었으나 본 발명은 IC 필터와 카운터회로 및 마이크로프로세서를 이용하여 지령속도의 전달을 정확하게 운행자에게 전달하므로서 열차의 안전운행을 도와주는 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ATS / ATC device for an electric vehicle, and more particularly, to a circuit improved to receive a signal transmitted from a center (command room), that is, a command signal accurately, and conventionally using a filter and decoder circuit composed of an LC circuit. There was a possibility that an error occurs in the data transmission error, but the present invention is characterized by helping the safe operation of the train by using the IC filter, the counter circuit and the microprocessor to deliver the command speed to the operator accurately.
