Research of Trains Arrive Early Warning System Based on WSN

摘要

With the rapid development of high-speed rail technology, the train speed is continually improve, which proposed a higher requirement for the many performance parameters of train arrived early warning. For the problem of domestic and international trains arrive early warning system functional limitations, combined with vibration detection sensor. The author proposed a train arrived early warning system based on ZigBee unlimited sensor network technology. The group testing results show that the system can achieve long-distance trains arrvive detection, cover a wide range of accurate early warning, high reliability and practicability, and meet the actual requirements of non-vehicle along the warning.
