Thunder and lightning optical image collection system based on FPGA

The utility model is suitable for a thunder and lightning information monitoring facilities technical field provides a thunder and lightning optical image collection system based on FPGA, including the photoelectric conversion module, high pass filter module, the AD module of sampling, FPGA module and camera, the photoelectric conversion module is the signal of telecommunication with the photoirradiation signal conversion of thunder and lightning, high pass filter module carries out the high -pass filtering to the signal of telecommunication, the electric signal transition of AD sampling pair of module post -filter becomes data signal, after handling, exports the signal of FPGA pair of module AD sampling module output lightning triggering signal, the camera according to lightning triggering signal acquire trigger constantly around the image data and the output in 1-3 second give the FPGA module, FPGA pair of module image data save with compress after send. The utility model has the characteristics of not disturbed by the bias light, the degree of accuracy is high, simple structure, easy to assemble etc, can extensively be used for the thunder and lightning image of overhead line, building or other ground objects to shoot research.
