The system used AT89C52 MCU and ADC0808 A/D chip, measured the electrical parameter of voltage, current and power with high speed and precision, and realized the process and memory of the sampled data. The whole system can be divided into data acquisition module and data display module. In data acquisition module, ADC0808 is working under the control of AT89C52, and the digital single can be got from ADC0808 output. In data display module, electrical parameters are displayed with LED. The system is simple, stable and reliable, also more easily to achieve the reasonable, accurate measurement and control, and the result can be intuitively read out on LED. This paper through the design of multi-channel electrical parameters acquisition system, improves the measurement precision and the real-time performance, so it can be extensively applied in practical production.
