Design And Research Of Intelligent Gas Valve Control System Based On Internet Of Things

In recent years,with the development of low-carbon economy and the enhancement of people's awareness of environmental protection,more and more people use gas instead of wood,coal and other polluted conventional energy sources.However,due to the chaotic operation of the bottled gas market and serious violation of regulations,some gas fillers often do illegal things such as filling air,using scrap cylinders and stealing cylinders for personal benefit.At the same time,at present,most gas filling stations use inefficient and error-prone manual methods to track and manage cylinder information,which leads to the problems of cylinder loss and difficult to retrieve,as well as various scrap bottles and retrofitted bottles still circulating in large quantities,which greatly increases the potential safety hazards of people using gas.In order to reduce this potential safety hazard and ensure the safety of people's personal and property,this paper carries out the design and research work of intelligent gas valve control system.Firstly,the principle of traditional gas valve control system is deeply studied.Aiming at the defect that it does not have positioning,chip identification and information tracking management,this paper improves the software and hardware of the traditional gas valve control system based on the Internet of Things technology,determines the overall structure scheme of the intelligent gas valve control system and expounds the principle of its realization.The whole control system of intelligent gas valve designed in this paper consists of four parts: intelligent gas valve,intelligent gas filling gun,gas cylinder with positioning function and remote monitoring system.Secondly,under the guidance of the overall structure scheme,the overall hardware design of the control system is completed according to the modular design idea,and detailed hardware design and circuit analysis are made for the minimum control system,RFID radio frequency,GPS positioning,GPRS communication,WiFi wireless transmission,electromagnet and other modules.Then,on the basis of the designed hardware circuit,the software programs of each module are written in C language,and the remote monitoring system is written in C# on the server side.At thesame time,the functions of each module are tested.Then,the function of data analysis and path planning is added to the remote monitoring system,and the optimal scheme is designed for the location of the subsequent inflatable station and the convenience of retrieving when the cylinder is lost.On the one hand,this paper uses fuzzy C-means clustering(FCM)algorithm to analyze the location data,and uses MATLAB to simulate the clustering centers.On the other hand,the electronic map is created by using MapInfo,and uses MapBasic language for secondary development.According to Dijkstra algorithm,the optimal tracking path of cylinders is designed and simulated.Finally,the intelligent gas valve control system and remote monitoring system are tested.Tests show that the intelligent gas valve control system designed in this paper has the functions of anti-disassembly,anti-charging,positioning,chip identification and information tracking management,and can meet the expected requirements.
