ARM-Based Petroleum Fracturing Liquid Level Monitoring System

MA Ruifeng;ZHANG Pizhuang;Shanxi Key Laboratory of Information Detection and Processing,North University of China;  
Aiming at the engineering requirements of real-time monitoring of liquid level in oil exploration operation,a real-time liquid level monitoring system based on ARM was designed.The system consists of three parts:ultrasonic transmitting and receiving module,wireless communication module and host computer terminal.Using ultrasonic ranging technology and 433 M wireless networking technology,the liquid level measurement and wireless data transmission functions are realized;Using the fact that the arm costs lowest power consumption in standby mode,different working modes are designed with hardware circuit design to reduce power consumption.The low power goal is achieved.The experimental results show that in the environment with low temperature and high humidity,the liquid level measurement accuracy reaches 1 mm,which can work continuously for a long time,and the wireless communication is normal,which is successfully applied in engineering practice.
