Acquisition System difficultly adapts to the requirements of high-speed data acquisition, instead of using FPGA to replace SCM (Single Chip Micyoco). The data acquisition system by the interface circuits, ADC, FPGA, oscillator and mixed with EEPROM, SRAM, non-volatile memory components is composed. The use of FPGA's I / O port complete the acquisition of eight-way switch. Analog through the A / D converter and the final use of the FPGA I / O port completes the simulation of acquisition. The results show that the method is simple and practical, can improve the speed of data acquisition, but because of relatively large size of FPGA chips is not conducive to anti-shock, the data acquisition system remains to be further improved.
