The Research And Design Based On The Single-chip Computer For The Rail-road Crossing Warning System

The traffic safety is one of the important elements for the rail traffic development, these days people want more and more fast training running speed, the traffic safety is becoming more important. Level road crossing is emphasis and weak point. So how to develop the security of the level road crossing is a very important problem..This article discusses the present situation of our rail level road crossing, use single-chip microcomputer system to design the coming vehicle automatic warning system for level road crossing. The core chip is 89C51 which has high reliability, low price and good universality. Most technicians can master it easily. The system gets the coming vehicles message, and gives notice to the crossing keeper and the people. So it can reduce the hidden dangers and provide the insurance for the rail traffic.Because of the bad running environment and working important, so we think much of the system running reliability, firmness of device and lightning-proof ability. Some measures also are taken in the software.Through the experience we can know that the system can realize the expected function well. It can provide the accurate message of the coming train in time for the crossing keeper. Especially in the rainy, smog, wind or sand days, the visibility is very bad, the importance of the system becomes higher. So the research and design of this system is very necessary.
