Accurate measurement of the drilling mud resistivity is very important to analysis of drilling parameters. Therefore, it is necessary to produce an accurate measurement system. The resistivity measurement system which is introduced in this paper adopts STM8s single chip microcomputer as the control center. It sends control commands via I2C technology and completes the measurement of resistivity using AD5933. Then data is sent to the MCU. When the MCU deals with the data, LCD screen displays measurement results. The system has so many advantages: low power, portable, real-time measurement etc. It provides a reliable basis for analyzing the parameters of drilling.

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.
