“四位一体”的家用燃气泄漏智能监控系统研究

Research on intelligent monitoring system of household gas leakage based on "four-in-one"

设计开发了家用燃气检测、报警、评估及控制"四位一体"的智能监控系统。该系统可以对家用燃气浓度、烟气浓度及环境温度进行实时检测,即使室内无人值守也能将燃气泄漏信号第一时间通过GPRS移动通信网络以短信方式通知用户及小区监控中心,并采取声光报警、自动打开排气扇/抽油烟机、自动切断燃气阀门等智能控制措施。同时还融合了燃气安全状况综合评估模块,对用户燃气安全状况进行准确评估,及时将评估结果反馈给用户。

Designed and developed the intelligent monitoring sys- tem of household gas leakage based on ＂four-in-one＂ including detection, alarm, assessment and control. The system can real- time detect household gas concentration, smoking gas concen- tration and environmental temperature and can use the GPRS mobile communication network to notify the user and communi- ty monitoring center even if no one is in. At the same time, it also can carry out intelligent control measures automatically such as sound and light alarming, opening the exhaust fan and lampblack machine and cutting off gas valve. And this system also has a comprehensive assessment of the gas safety situation which can assess gas safety status of the user accurately and feedback the results to the user in time.
