Research And Application Of Power Monitoring System Based On Data Relay And Emergency Communication

The application of wireless communication technology in power monitoring system has always been a particular area of attention,through the combination of wireless communication technology and data relay system,it can let the electric power monitoring system get rid of the shortcomings of the traditional cable communication mode,overcome the distance,weather,building block and other factors,so that the signal coverage without dead ends,the whole system has become more stable,More anti-interference ability,power transmission process has become more secure and reliable.The main points of the paper are summarized as follows:1.This paper introduces the history,current situation and development of power monitoring system and wireless communication technology,introduces and compares the current wireless communication methods,and then leads to the main contents of this paper.2.Through the characteristics and advantages of 4G network technology,the feasibility of 4G network technology in power monitoring system is analyzed,and then the networking scheme is determined and 4G DTU is introduced.At the same time,the advantages and disadvantages of several short-range wireless communication technologies are analyzed and analyzed.The feasibility of WiFi application in wireless emergency communication system is analyzed,and the ESP8266 module is introduced.3.This paper introduces the modules of the power monitoring system based on data relay,which is divided into the analysis of CDT protocol,the configuration and use of 4G DTU,the use of cloud server and the function of data relay program.4.Design and implementation of a power wireless emergency communication system,composed of two subsystems and the client subsystem.First introduced the framework of the power wireless emergency communication system.Then,the hardware design and hardware wiring of the system are introduced.Finally,the software design of the system is analyzed in detail.The software level of the system is divided into three parts:serial port program,client main program and main program of the server.Test results show that the system can achieve the client to connect to the server,and complete the hexadecimal data transparent transmission.Based on the wireless network technology,this paper not only involves the 4G wireless network,but also studies the way of transmitting data through the WiFi wireless network,which has strong engineering practice significance.The actual test proves that it has strong reliability and flexibility.
