一种旅客列车的无线烟雾报警系统

A wireless smoke alarm system for passenger trains

硬件选用AVR单片机作为微控制单元,采用模块化的方式,设计出烟雾探测器、集中报警主机、报警分机和手持式的车号修改器等各模块硬件的电路;软件选用的是易模块化的且具有良好的可读性的C语言来设计嵌入式程序。在将设计好的旅客列车无线烟雾系统的每个功能在实验室测试完毕后,也在旅客列车实际的运作条件下对每个模块完成了综合全面性的测验。各种检测结果体现了本项目设计的无线烟雾监测报警防范系统不只是满足了旅客列车在火灾防范预警方面的要求,而且操作起来容易,性能也相对比较好。

AVR series monolithic integrated circuit is selected to work as MCU,functions modularly to carry on the smog detection,the warning main unit,the warning extension telephone and the hand held passenger car number revision. Various functional modules are designed for hardware circuit and the embedded software. The software uses the C language to develop,which is easily modulated,has a very good readability. After the systems prototype manufacture completed,various functional module accent test has been completed under the laboratory environment,and online test has been carried out for passenger train under actual operating condition. The results indicated that this project develops the wireless smog alarm system to fulfill the passenger train requirement of forewarns regarding the fire prevention,and it＇s easy to operate and stable to performance.
