摘 要:随着我国经济的快速发展,铁路网络变得更加发达,铁路道口也随之增多。由于我国铁路采用客货混合运输模式,特别是近年来经过数次提速以后,线路上列车速度存在很大的差异,所以对这些大量存在的铁路道口的管理成为一项复杂而繁琐的工作。针对这种情况设计了一套基于ZigBee和GPRS技术的铁路无人看守道口无线预警系统,能实现列车接近检测并发出声光报警、列车到达撤销预警、预警系统故障自检测等功能,为铁路行车安全保障提供了一个低成本、高可靠性的解决方案。
关键词:铁路道口 ZigBee ieee802.15.4, GPRS 无线预警系统
Abstract: With the development of our economy, there are many different railway crossings which were bringing dangers to passerby without administrating in China. To provide a safe circumstance for passengers and drivers, it was given a useful design based on ZigBee and GPRS embedded technology. The system can warm the passengers and open the electric hooter and display the running of the train in the screen. The self-detection ability can also detect the system’s failure by itself. It provides a low cost and high reliability safeguard for railway system.
