In order to meet the strict requirements of precision, real-time and synchronization of data acquisition in the process of precision equipment monitoring, a multi-channel, real-time and high-speed data acquisition system based on FPGA is designed. This system uses the Spartan6 series FPGA of Xilinx as the core control device, which realizes functions such as data acquisition control, data buffering, data processing, data storage, data transmission and synchronous clock control. The test shows that the scheme has the advantages of high precision, fast speed, good reliability, strong real-time performance and low cost.
