Abstract: In view of problems of big error and easy to fall into danger that control of existing underground transportation locomotive adopted manual correction method by driver, a control system of underground unmanned transportation locomotive based on fuzzy control was designed. The system uses fuzzy control technology, adopts STM32F10 single-chip microcomputer as main control module, frequency converter as actuators, so as to control motor speed, and achieves the goal of rate control, brake and obstacle avoidance. Meanwhile, the system can use the upper monitoring system to real-timely monitor transportation locomotive, implements unmanned and intelligentialize for the underground transportation locomotive, and improves the safety of mine production.
