| Abstract: | The paper presents a design which consists of a serial TLC2543 chip, high-speed 6N137 chips and some other peripheral auxiliary chips and builds up a data acquisition system of high cost performance which can work well in strong noises environment. It also discribes the block diagram of the main chip and interface circuit and software flow chart. The system has been proved in pratice to have the following merits. Such as low-cost, high precision and reliability and simple interface. It is good for practice in resisting process passage disturb. |
