Design And Implementation Of Civil Air Defense Monitoring System Software Based On Visualization Technology Of Internet Of Things

Civil air defense project is related to the safety of the country,people's lives and property.It is a key project that can not be ignored.Civil air defense engineering has a large number of fans,valves,pumps and other equipment,as well as temperature and humidity monitoring,poison gas measurement,air pressure monitoring and other related sensors.The status of the equipment are related to whether the underground civil air defense engineering can meet the protection requirements,and the value of key data is an important reference for operational command.The reading and display of alarm status and key data are particularly critical.Aiming at the drawbacks of data access in the original air defense engineering monitoring system and adapting to the intelligent development of the underlying hardware equipment,and meeting the new functional requirements of the air defense engineering in the new era for the monitoring system,this paper designs a civil air defense engineering monitoring system based on the sub/pub mode of the Internet of Things and using the relevant visual components.Major innovations include:(1)Using sub/pub mode and MQTT protocol to access data to solve the problems caused by driver in the original system.(2)Aiming at the new communication protocol and data format,the corresponding parsing program is compiled,and the data is stored in different classes.The system software realizes the function of equipment status monitoring,key data monitoring and alarm management.(3)Use time series data.The key data historical values in a specific period of time are queried by setting query time,and displayed in a broken line chart,which provides data basis for accident cause tracing and alarm prediction.(4)Establish electronic files for field equipment,manage all information values in its whole life cycle,and provide information such as operation manual,maintenance manual,emergency handling methods to assist field personnel in solving equipment failure.The system is finally applied to an air defense project in Shijiazhuang.It realizes the functions of condition monitoring,remote control,issuance of three defense commands,storage and display of key data historical records,storage and display of equipment assets details,and meets the functional requirements of system requirements analysis.
