Abstract
With MCU STC89C52 as the controlling core, by simulating the multi-channel selector CD4067 and high precision A/D converter AD574A, a multi-channel high-precision data acquisition system is designed in this essay. Data communication, acquisition as well as management are carried out between computer and MCU through RS 232. This system can satisfy the requirement of data acquisition after site test, and it is can be widely used in all kinds of multi-channel data acquisition system with high-precision.
