Design For Sferics Monitoring System Based On 4G Communication

Against the background of the rapid rise of China’s mobile communication network,4G communication,WiFi and various wireless communication technologies have been applied in all aspects of our lives.At the same time,in the field of lightning monitoring,the design of lightning detection system with high performance,compact and easy to install is becoming more and more significance.At the same time,the drawbacks of traditional lightning detection system become increasingly exposed,including the inconvenience of network cable laying and the high cost of construction.Nowadays,in order to solve this problem,it is significant to design a lightning detection system with small size and easy installation.At the same time,its hardware system design is compact,robust and highly integrated.It is also indispensable to facilitate outdoor installation and debugging.This issue has attracted extensive attention of scholars and engineers.Through the analysis of the drawbacks of the existing lightning monitoring system,the power control system and data transmission mode are upgraded.By this way,the daily operation of the whole base station can be more reliable and stable.The main contents of this paper are as follows:1.A mixed analog-digital data acquisition circuit board is designed,and the core development board TE0720-03-2IF,4G communication module and GPS module with ZYNQ chip are integrated in the board.The basis of data acquisition circuit design is introduced.The circuit board drawn by Altium Designer 6.9.Finally,the finished product is produced.2.Based on the test board named Zedboard with ZYNQ chip,high-performance transmission interface of ZYNQ is used to complete the interaction of high-speed data.The data is transmitted between PL and PS.The collected data is stored in DDR3,and the calculation task is reasonably assigned.Finally,the test of data transmission is completed on Zedboard,and the data collected by the astroelectric detector analyzed in real time in Linux system.The operation is simple,stable and efficient.3.A bipolar power supply system based on solar cells is used.First of all,we need to understand that solar energy output can not be directly used as the power supply system of the sky-magnetism lightning monitoring system.We need bipolar voltage output which is larger than±12V,so it can not be achieved by linear regulator alone.Here we think of the combination of linear regulator and switching power supply.This idea is also widely used in the current power management methods.In the design process,the ripple suppression of the input power supply and the voltage value measured on-load are analyzed.Finally,the circuit board is designed and welded,and the correctness of the theory is tested and verified.4.In this paper,a scheme of data transmission of sky-magnetism lightning based on 4G communication is proposed,and the development and design of the upper computer software of the system are completed.This paper expounds the design ideas of the upper computer software,the use of software controls,the design of software interface,and the peanut shell port mapping to penetrate the internal network for easy use in the main station server.Finally,it verifies whether the software can well complete the wireless transmission between the sky,magnetism,lightning data and the main station,and to the sky power.The data are analyzed simply,and the geographic position and waveform of celestial electricity are displayed intuitively.
