摘　　要：介绍燃气泄漏报警器的高抗干扰性燃气模组、联动设备不联动的自检系统、防反接电源电路,以及燃气泄漏安全切断技术的功能结构设计与工作原理、燃气泄漏报警器状态提示功能。通过采用延时报警手段、联动设备不联动的自检系统以及防反接电源电路的设计,实现了燃气泄漏报警器的高抗干扰性,并且使联动设备不会因燃气泄漏报警器自检而误动作,还可以避免燃气泄漏报警器因电源线反接而造成的损坏。通过将燃气泄漏报警器技术与燃气表安全切断技术相融合,形成燃气泄漏安全切断技术,可以实现燃气泄漏的实时感知与安全切断。通过燃气泄漏报警器状态提示功能,进一步保障了燃气使用的安全管理。The high anti-interference gas module, self-checking system of linkage equipment not linked, anti-reverse connection power circuit of gas leakage alarm as well as the functional structure design and working principle of gas leakage safety cut-off technology, and the status prompting function of gas leakage alarm are introduced. The high anti-interfer- ence of gas leakage alarm is achieved by using the time delay alarm method, self- checking system of linkage equipment not linked and anti-reverse connection pow- er circuit design, and the linkage equipment will not malfunction due to self-checking of gas leakage alarm, and the damage of gas leakage alarm caused by power line reverse connection can be avoided. By combining the gas leakage alarm technology with the gas meter safety cut-off technology, the gas leakage safety cut-off technology is formed to realize the real-time sensing and safety cut-off of gas leakage. At the same time, the safety management of the gas use is further ensured through the status prompting function of gas leakage alarm.
