中文摘要:
      针对城市公交车缺乏对易燃易爆品采取有效监测措施的问题,提出一种在公交车上使用便捷的可燃气体监测与无线报警系统. 该系统以STC12C5160S2单片机为控制核心,采用了对汽油、 柴油等挥发气体灵敏度高的可燃气体浓度检测传感器,实现对车上可燃气体浓度的实时监测. 为了减少系统误报警和漏报警,对公交车内气体浓度变化的状况进行研究,提出分级式报警方案. 最后,在公交车上配备系统并进行测试,实验结果表明,可燃气体,监测与无线报警系统具有良好的可行性和实用价值.
英文摘要:
      Aiming at the lack of effective detection measures for the inflammable and explosive materials in public transport,so the paper presents a kind of bus-mounted combustible gas detection and wireless alarm system. The system takes the MCU of STC12C5A60S2 as its core,using the combustible gas concentration sensor,which has high sensitivity to volatile gas such as gasoline and diesel,so that the system realizes real time detection of the concentration of combustible gas in the bus. In order to reduce the error alarm and leakage alarm,the status of the gas concentration in the bus is studied,and a hierarchical alarm scheme is put forward. the system is installed and tested on the bus. The experimental results show that the combustible gas detection and wireless alarm system has good feasibility and practical value.
