Remote control for an electrical, locally activated point in rail-bound traffic system, comprises infrared transmitter and infrared receiver, with signal transmission between them taking place by coded infrared rays

摘要

The remote control comprises an infrared transmitter (1) and an infrared receiver (2). The signal transmission between the transmitter and receiver takes place by coded infrared rays. The signal evaluator (3) is connected to the receiver and is switched in such a way that upon receiving a correctly coded change-over signal, the assigned output to the microprocessor or the programmable logic controller (PLC) (4) can be controlled and the point is changed over.
