Automatic Positioning Control System of Train
A type of automatic positioning control system of train has been introduced. The key element of system is based on induction radio communication technology. System is composed of four parts: ground control unit, communication unit, train control unit and external control part. The carrier of position produced by generator is amplified and sent to the coded flat cable. Then the signal is induced by antenna of train. Through control unit of train, the location of train will be gained. The location signal is sent out to PLC control part which will control some external equipment. It is especially for real-time address detecting online of subway or light rail trains during running. Several functions of automatic stop, positioning, opening, closing and others have been achieved in this control system.
