基于GPS和GPRS的铁路道口预警装置的研究

随着铁路网络的日益发达,铁路道口也随之增多,对大量的铁路道口管理逐渐成为一个复杂繁琐的问题.传统管理采用人员值守,将耗费大量的人力物力,而当前的无人值守道口由于缺少有效提示使得行车及行人安全得不到保障.针对该情况,设计出了一套基于GPS、GPRS、嵌入式电子技术和计算机软件的铁路道口预警装置.实现列车进入道口前自动提醒驾驶员、启动电子汽笛装置及地面道口电子警示牌、记录显示列车行驶状况等功能.通过PC机上的列车信息记录交换软件,交换更新列车行驶信息以便分析其运行情况.给出系统的硬、软件设计,为铁路行车安全保证提供一个较低成本的解决方案.

Research on early warming device for railway crossing based on GPS and GPRS

There were many railway crossings without administrating in China, which were bringing dangers to passersby. To avoid this phenomenon, and provide a safe circumstance for passengers and drivers, it was given a useful plan based on GPS (Global Position System), GPRS (General Packet Radio Service), embedded electronic technology and PC software. The device which designed according to the plan would warm the train driver, open the electric hooter and ground electronic display automatically, and record the running messages of the train. And this device could exchange messages with PC through the software for analysis and data update. Now, it was given the particular design of hardware and software, which provided a safeguard for railway system.
