Design of multi-channel data acquisition and transmission system

Abstract

Aiming at a multi-channel data acquisition and transmission system based on FPGA, the design scheme, functional circuit and logic design method of the system are introduced in detail. The system uses FPGA as the control core to control TLC2543 analog-to-digital converter and complete the circulation acquisition of 11-channel analog data. The transmission end uses Ethernet chip RTL8201 to communicate with the upper computer, which can monitor the data changes of each channel. The correctness of each function module is verified by software simulation. The design can meet the requirements of multi-channel signal acquisition and transmission.
