Design of Multi-channel Data Acquisition and Transmission System Based on Ethernet
In order to meet the requirement of multi-channel analog signal data acquisition in the field of weapon equipment automatic testing,a multi-channel data acquisition system controlled by Ethernet is designed.The system uses FPGA as the main control,and completes the data acquisition and transmission of 32 analog signals through the Ethernet transmission protocol.After experimental verification,the Ethernet transmission rate can reach up to 580 Mbps,and the maximum error of multi-channel ana-log data acquisition is 0.43%,which meets the design index of acquisition accuracy better than 1%.Now it is applied to a certain type of editing equipment.
