| Abstract：A method for massive data acquisition system is introduced.This system solves the problem of multichannel,highspeed and realtime acquisition in the petroleum pipeline detection.FPGA is used to acquire 400 channels at the rate of 1 kHz per channel.The massive wires between sensors and FPGA controlling board can be simplifed by SPI bus.Real time in acquisition and miniaturization in design are also achieved.The data and waveform recorded in the experiments prove the feasibility of the system. |
