Researches On The Temporary Speed Restriction Warning And Control System Of Train

Railway is the backbone of domestic comprehensive transportation system, aswell as the main artery of national economy. With the rapid development of economy,railway has got a phenomenal acceleration---the running mileage is increasingprominently, the speed is being picked up remarkably. In order to make full use ofcarrying capacity and take possession of high transport efficiency, we should keep thetrain run with high-speed while ensure its safety. But we often need to take temporaryspeed restriction on some parts of the railway because of track construction or damage.However, the location and time are both unpredictable with heavy randomness andsuddenness, and the value of temporary limited speed vary frequently so as to adjustto the quality of railway line. And we can come to the conclusion that temporaryspeed restriction make extraordinary potential safe hazard to train operation.This project undertakes temporary speed restriction warning and control systemon the basis of RFID technology, accomplishes following jobs during the research:1. Research on the protection measures of temporary speed restriction area, andfigure out the comprehensive scheme of temporary speed restriction warning andcontrol system through the investigate in the fields.2. Choice appropriate RFID devices, develop vehicle-mounted host and displayand warning terminal independently, fulfill the software and hardware design of thesystem, realize this temporary speed restriction warning and control system.3. After the actual test of this temporary speed restriction warning and controlsystem at the rear of this project, we can come to the conclusion that the aforesaidsystem is able to adjust to train environment. And the system has high feasibility totransmit speed restriction information between the ground and train, notable stabilityof devices, as well as distinguished rationality of system architecture.This utility project work on temporary speed restriction warning-control system,realize the speed restriction information auto-transmission between the train andground, implement auto-warning and control when the train go through thesetemporary speed restriction area, fulfill the previous target.
