Mining super high -density resistivity method appearance self -adaptation data acquisition system

The utility model provides a mining super high -density resistivity method appearance self -adaptation data acquisition system, the FPGA treater is electric connection PC machine and m sequencer respectively, M sequencer electric connection signal -radiation module, signal -radiation module electric connection current measuring module, signal processing module, FPGA treater, PC, m sequencer, signal -radiation module and the equal electric connection system power supply of current measuring module. The FPGA treater is then controlled m sequencer and is produced interference killing feature the longest strong pseudorandom code binary sequence, and then make emission current's width random variation, positive and negative square signal appears in the range cycle, therefore, it is poor to have overcome traditional high -density resistivity method appearance data acquisition system interference killing feature, measurement accuracy is low, resolution ratio is low, the unstable problem of system performance, can su
