摘要
分析居民用户因燃气泄漏引发的各类异常风险工况的特征,确定异常风险工况的判定条件。据此开发出基于物联网燃气表的户内燃气安全保护技术,物联网燃气表将检测到的计量数据与燃气表内置的判定条件进行比较,判定用气是否属于异常风险工况。如果属于异常风险工况,则及时进行预警或切断气源供应,保障安全。
The characteristics of various abnormal risk conditions caused by gas leakage in residential households are analyzed,and the judging conditions for abnormal risk conditions are determined. According to this,the indoor safety protection technology based on the Internet of Things gas meter is developed. The Internet of Things gas meter compares the detected measurement data with the built-in judgment conditions of the gas meter to identify whether the gas use is in an abnormal risk condition. If it is an abnormal risk condition,the meter will promptly warn or cut off the gas supply to ensure safety.
