Abstract
Description
技术领域technical field
本发明属于安全监测技术领域，涉及燃气报警、关断装置的控制方法。The invention belongs to the technical field of safety monitoring, and relates to a control method of a gas alarm and shut-off device.
背景技术Background technique
目前为了保障燃气安全，国内出台政策安装燃气安全智能检测装置，其功能实时对燃气使用和燃气管路进行检测。对燃气因使用或管路泄露进行智能判断并干扰将燃气表内气阀关闭，并将信息上传管理部门，提醒使用者和管理者提前预知并及时处理，避免燃气因泄露导致事故的发生。目前燃气报警关阀的方法:一是燃气报警器通过有线连接控制关闭管道燃气阀门。二是通过燃气报警器的触发NB-lot窄带物联通信控制燃气管道阀门关闭。三是通过燃气报警器触发蓝牙通信关闭燃气表内电控阀门。第一种燃气报警器端需接220V电源供电，有线传输数控，材料成本高，施工成本高，管道安装有源电控阀门存在安全隐患，不能上传信息。第二种燃气报警器端也需220V电源供电，无线NB-lot传输数控，材料成本更高，安装施工成本高，管道安装有源电控阀门存在安全隐患，可上传信息。第三种燃气报警器端也需接220V电源供电，无线蓝牙通信，接收端需独立电池供电，功耗高，材料成本较高，蓝牙模块如接燃气表中电池则不能长时期供电，以免影响燃气表正常工作，可通过燃气表内NB-lot上传信息。以上三种解决燃气报警关闭燃气阀门的方法都源于报警器端信息判断，没有增加补偿判断，而且解决方式材料成本高，施工成本高，管道安装阀门存在连接隐患，数据上传有限，不利于燃气经营与管理，不是最佳的解决方法。At present, in order to ensure gas safety, domestic policies have been introduced to install intelligent gas safety detection devices, which function to detect gas usage and gas pipelines in real time. Make intelligent judgment on gas usage or pipeline leakage and interfere with closing the gas valve in the gas meter, and upload the information to the management department to remind users and managers to predict in advance and deal with it in time to avoid accidents caused by gas leakage. The current gas alarm valve closing method: First, the gas alarm controls and closes the pipeline gas valve through a wired connection. The second is to control the closing of the gas pipeline valve through the NB-lot narrowband IoT communication triggered by the gas alarm. The third is to trigger the bluetooth communication through the gas alarm to close the electronically controlled valve in the gas meter. The first type of gas alarm needs to be connected to a 220V power supply, and the numerical control is transmitted by wire. The material cost is high, and the construction cost is high. The installation of active electronically controlled valves in the pipeline has potential safety hazards, and information cannot be uploaded. The second type of gas alarm also requires 220V power supply, wireless NB-lot transmission of numerical control, higher material costs, high installation and construction costs, and the installation of active electric control valves in pipelines has potential safety hazards, and information can be uploaded. The third type of gas alarm also needs to be connected to a 220V power supply. For wireless Bluetooth communication, the receiver needs to be powered by an independent battery, which has high power consumption and high material cost. If the Bluetooth module is connected to the battery in the gas meter, it cannot be powered for a long time, so as not to affect the The gas meter is working normally, and information can be uploaded through the NB-lot in the gas meter. The above three methods for solving the gas alarm and closing the gas valve are all derived from the information judgment of the alarm terminal, without adding compensation judgment, and the solution method has high material cost, high construction cost, hidden danger of connection of pipeline installation valves, limited data upload, which is not conducive to gas Operation and management is not the best solution.
