Design of real-time measurement system for lightning current parameters

In this paper,a real-time measurement system for lightning current parameters is designed.First,the principle for magnetic tape measure lightning current parameters is introduced.Then,single chip microprocessor technique is used to control the magnetic tape machine,which realize real-time measurement of lightning current,and GPRS wireless communication network and internet communication network is used for remote transmission of lightning current parameters.Finally,Visual C＋＋ is used to design the data monitor center,which will analyze the data transmitted from measure module and work out the parameters such as lightning current peak,lightning current steepness.Experiments show that the system can process long-range and regional acquisition of the lightning current parameters.What＇s more,it can quickly and accurately locating the lightning strike point,accurately figure out the regular pattern of the lightning activity,and effectively monitor and early warn the lightning.The system has some practical value.
