A Design of lightning detection instrument based on SOPC

Lightning detector is an application instrument,which can collect electromagnetic field on atmospheric to detect lightning signal and recode corresponding time information.Widely-used lightning detector in our country has some shortages,such as low integration,high power,poor detection performance,etc.In this paper,a novel lightning detector is presented.Using system on programmable chip(SOPC) technology,Nios Ⅱ CPU,lightning recognition and local clock modules are integrated in a single FPGA.Compared with the older generation instrument,our lightning detector has advantages of higher integration,lower power and improved detection performance.Through consistency test and network positioning experiment,this novel lightning detector has been employed by Chinese Lightning Monitoring Net.
