摘要To address the issue of insufficient channel capacity in single-signal acquisition systems at industrial sites,this paper designs a multi-channel data acquisition system based on embedded chips.The system adopts an architecture comprising an embedded controller and a host computer:the embedded controller handles signal conditioning,analog-to-digital conversion,filtering,and data transmission for multiple channels;while the host-computer software provides functions such as user login,data reception,real-time display,and storage.The modular architecture supports the conditioning and acquisition of voltage,current,temperature,and humidity signals.Test results showed that the relative errors of the voltage and current channels were below 1%,and that the system could acquire,transmit,display,and store the measured data.
