Data collection and munication control using modular design, AT80C51 with the single chip processor as the core, and using the serial A/D conversion module TLC2543 for conversion module, and to realize the 8 signal collection, storage, display and with A PC munications, and other functions. Some applications software written in C language control software, for data acquisition systems, modulus conversion system, data display, data munication and other procedures to carry on the design.
