Light Rail Station Key Techniques Of Intelligent Door Control System

Light rail station intelligent door control system is to ensure the safety of train operation and improve the operation efficiency of important equipment。Its function is to realize the train operation safety control,as well as positioning the linkage of the train door and platform screen door when parking。It is a great significance,in order to get rid of in the related areas of foreign technology monopoly and promote the progress of the urban rail transit equipment, current situation of domestic gating technology, study and grasp the light rail station intelligent door control system of the key technology.Not only light rail station are analyzed in this paper the basic composition of intelligent door control system, but also we conducted in principle to the system design for control of key parts. In door control unit design, the paper puts forward a central controller to control both the security point of view, then implement two door started, at the same time closed at the same time. It is accurate, achieve the security, easy to control. We use the brushless dc motor as the system output, so that guarantee the stability of the system output torque and rotational speed, and power output under the same condition, the volume is small, the power consumption is also smaller.In the design of intelligent gateway, through CAN and MODBUS, we implemented the door control unit and the main controller of two-way communication. Power supply system adopted the advanced UPS and full digital processing. The technology makes the control circuit, parameter setting and operation management make more perfect. The introspection and the detection function become more powerful. After completing this topic, greatly ensure the light rail station intelligent door control system running stability and reliability.
