The utility model relates to an intelligent gas meter with gas leak alarm and control functions. 本实用新型涉及一种有燃气泄漏报警控制功能的智能燃气表。
The news of the radiation leak caused widespread public alarm. 辐射泄露的消息引起了公众的普遍恐慌。
The problem of use safety of the gas is mainly solved by installing a gas leak alarm device, a mechanical arm controlled by an alarm and an electromagnetic valve. 燃气使用安全问题主要靠安装燃气泄漏报警器、报警器控制的机械手、电磁阀来解决。
So far I've completed three inventions: Tap water leak self-closing valve, Wireless mobile monitor alarm and Dynamic measuring device for High-speed railway track horizontal and vertical displacement. 到目前为止,我已经完成了三项发明,“自来水失控泄漏自关阀”、“无线移动监控监听报警器”和“高速铁路轨道线路横向、垂向位移动态测量装置”。
This system detects, locates leak point within 3 minutes after its occurrence, geographical information is shown on the computer screen and alarm is running when a leak is detected; 泄漏发生后,该系统可以在2~3分钟内自动完成泄漏检测,给出泄漏点定位和声光报警,同时在主画面上弹出泄漏点附近的地理信息图;
Research of ADBS application to natural gas leak intelligent alarm system 主动数据库技术在天然气泄漏智能报警系统的应用研究
Moreover, the normal pattern or abnormal pattern is not perfect and the false alarm rate and leak alarm rate are very high. 另外,所建立的正常模式或异常模式也不够完善,容易造成误警或漏警,给网络系统造成损失。
As the most common anti-theft alarm, gas leak warning, fire alarm systems, their functions are too single and have a serious flaw-can not remote real-time automatic alarm, the guards on duty have to timely discovery of unusual circumstances. 而作为最常见的防盗报警、燃气泄漏警示、火灾报警系统,它们的功能单一并且有着严重的缺陷&不能远程实时自动地报警,并且需要值班人员的看守来及时地发现异常情况。
The Smart Home System contained five subsystems: temperature control system, lighting control system, gas leak alarm system, fire alarm system and smoke alarm system. 智能家居系统包含五个子系统:温度控制系统、湿度控制系统、煤气泄露控制系统、火灾报警系统和烟雾报警系统。
As a result, researching Kalman filter algorithm, in the premise of, reducing model uncertainty and signal disturbance on pipeline leak detection and location accuracy, and decreasing the leakage false alarm have significant theoretical significance and application value. 因此,研究Kalman滤波算法,减小模型的不确定性和信号扰动对管道泄漏检测与定位精度的影响,降低泄漏误报率,具有重要的理论意义和应用价值。
