The Research To Anti-Slip System Of Arrival-Departure Vehicles Base On PLC

Nowadays, with the high-speed development of the railway transport industry, Request to increase the automation level of the arrival-departure operations. Anti-slip operations of arrival-departure is an important part of transportation.Today, a lot of anti-creep devices in train control yards have also adopted traditional techniques such as brake shoes and the hand brake, however it is ineffective and has potential safety hazards. Though, the end of Hump operations started some new application of the system of anti-slip device in recent years, most of is hydraulic cylinder and air pressure, However, the technical surviving in this or that Inadequate. The overall level of automation is not high.It is basically blank in the vehicle anti-slip operationsin Intermediate station.Therefore,according to the ZT-1 type Hump End Car Stopper developed by southwest Jiao Tong University's research and development team, they have improved the basic, optimize configuration. The author have research and design a new anti-creep device. This device adopts the CPM2A system PLC of Omron Corporation. To achieve the brake control, status monitoring and fault protection of Anti-slip brakes in the arrival-departure.Communicated brake and track signal between lower computer and upper computer by net.The system, control track has adopted an excellent modular design. Each PLC controls 4 tracks. Between PLC and upper computer, they use HOST LINK network to communicate. And it can distinguish fault and alarm for disorder, and can also make system maintenance warning. At the same time it can check the train's location. This system will increase work efficiency greatly. And also decreases the worker's labour intensity and chances of accidents.
