Abstract

The invention relates to the field of lightning monitoring and early warning, in particular to a multi-channel comprehensive lightning monitoring instrument. The multi-channel integrated lightning monitor includes multiple lightning pulse sensors, overvoltage / overcurrent protection circuits, amplitude conversion circuits, real-time numerical sampling modules, processors, data storage, clock circuits, monitoring and control systems, and power supply circuits. The signal output terminal of the lightning pulse sensor is connected in series with an overvoltage / overcurrent protection circuit, an amplitude conversion circuit, a real-time numerical sampling module, and a processor in sequence, and the processor is also respectively connected with a clock circuit, a data memory, and a monitoring and control system. The invention can accurately record the waveform, amplitude, frequency and occurrence time of the surge voltage generated by direct lightning strike induction in multiple areas, and can also monitor the working status of the remote lightning protection device with remote signaling function in real time And real-time monitoring of the voltage value between zero and ground, and detection of grounding resistance. Relevant data information can be displayed in real time through the local monitor, and the data can also be transmitted to the remote computer through the serial port line to realize computer viewing and computer monitoring.

Description

technical field [0001] The invention relates to the field of lightning monitoring and early warning, in particular to a multi-channel comprehensive lightning monitoring instrument. Background technique [0002] my country is a country with frequent lightning disasters. With the development of electronization and informatization, a large number of electronic equipment such as communications, computers, and switches are widely used in people's lives. These electronic equipment have low withstand voltage and are easily damaged by lightning current. With the improvement of people's requirements for surge protection, it is a basic work to do a good job in lightning protection by analyzing the characteristics and laws of surge voltage generated by lightning strikes on the line, and record the specific conditions of surge voltage generated on the line when lightning strikes occur It is the foundation. At present, the lightning recording devices on the market can only record the a...
