摘要

PURPOSE: A wireless opening/closing device for sensing trouble in an electric rail car door is provided to allow a worker to easily select an opening/closing mode of an electric rail car door with a simple button operation by operating a portable wireless RF transmitter. CONSTITUTION: A wireless opening/closing device for sensing trouble in an electric rail car door comprises a central control unit(101), a door control unit(103), and a data transceiver unit(102). The data transceiver unit transmits and receives data from the central control unit and the door control unit. The central control unit includes a microcomputer controller(110) equipped with an RF receiver(111) and an RF transmitter(120) for transmitting a door opening/closing signal to the RF receiver. The microcomputer controller comprises an input signal processor which processes received opening/closing signals, an output signal converter, a door opening/closing signal output part, and a switch operating part which control the on/off state of the microcomputer controller and the opening/closing mode of the door.
