The display of ordinary voltmeter is not clear enough, the measurement range is narrow and the anti-interference ability is weak. This paper studies the design and Simulation of voltage measurement system based on ADC0809. Combined with the actual production situation, using the function that ADC0809 has 8 analog inputs and can convert the analog input into digital display, this paper designs the circuit with single chip microcomputer chip AT89S51. Combined with the working principle of a / D converter and DC digital voltmeter composed of them, the voltage measurement of 0-10V is realized in this paper. The experimental results show that the measurement system has the advantages of accurate reading, wide measurement range and micro power consumption.
