A kind of real-time measurement system of mud flow- rate in underground mine is designed. The measurement system mainly includes ultrasonic sensor, hardware circuit and measurement software. The main control unit of the system adopts C8051F500 MCU.The measurement model of time-difference is the core of the system. In this model, the TDC-GP22 chip is used to measure time-difference of ultrasonic transmission in mud. Its accuracy is picosecond levelso that the system can improve the measurement accuracy of micro-velocity. The simulation experiments were carried out under indoor conditions. The experimental results show that the system works steadily and realizes the function of measuring mud flew velocity. The system can effectively measure the change of mud flew velocity. Through research and design, the technology application is explored.It lays a foundation for further research and application of this technology.
