互联网技术在燃气终端安全监控方面的应用

Application of Internet Technology in Safety Monitoring of Gas Terminals

随着天然气清洁能源的普及,燃气安全问题也日益凸显,而室内燃气安全更是得到广泛关注,虽然国家和地方政府为了减少室内燃气火灾爆炸事故的发生,出台了不少关于用气安全方面的法律法规,比如有燃气经营企业有义务每两年入户安检一次的规定,但是目前室内燃气安全依然停留在基本安全的层面。为了实现从基本安全向本质安全的转变,使得通过后台终端就可以轻松对每一位用户进行安全检查,我做了以下研究。通过在用户端安装可以自动启闭的电磁阀和微型压力变送器,并将电磁阀和微型压力变送器通过信号线与物联网智能燃气表相连接,再通过为燃气表添加安装特定的模块,使得可以通过NB-IoT网络进行双向传输,再通过云数据进行数据处理,最后以达到通过后台系统对燃气用户端气密性检测和监控的目的。通过该项技术可以实现居民用户每天进行一次安全检查的目的,实现燃气终端用户的本质安全。可以减少因入户安检到访不遇和安全隐患排查不及时而导致火灾爆炸的问题,也可以为燃气经营企业对用户端的安全检查和监控提供极大的便利。为燃气经营企业节约大量的人力成本的同时还可以有效的减少安全事故的发生。

With the popularization of natural gas clean energy,the problem of gas safety has become increasingly prominent,and indoor gas safety has received more and more attention.Although the national and local governments have issued many laws and regulations on gas safety in order to reduce the occurrence of indoor gas fire and explosion accidents,such as the provision that gas operating enterprises have the obligation to conduct household security inspection every two years.However,the safety of indoor gas is still at the level of basic safety.In order to realize the transformation from basic security to intrinsic security,and make it easy to check the security of each user through the background terminal,I have done the following research.By installing the solenoid valve and micro pressure transmitter that can be opened and closed automatically at the user end,and connecting the solenoid valve and micro pressure transmitter to the intelligent gas meter of the Internet of things through the signal line,and then adding and installing specific modules for the gas meter,the two-way transmission can be carried out through the NB-IoT network,and then the data processing can be carried out through the cloud data.Finally,in order to achieve the purpose of detecting and monitoring the gas tightness of gas users through the background system,this technology can realize the purpose of safety inspection for residential users once a day,and realize the intrinsic safety of gas end users.It can reduce the problems of fire and explosion caused by missing security inspection visits and untimely troubleshooting of potential safety hazards,and also provide great convenience for gas operating enterprises to conduct safety inspection and monitoring on users,which can not only save a lot of manpower costs for gas enterprises,but also effectively reduce the occurrence of safety accidents.
