For the problem of safety accident such as the collision between equipment or between person and equipment beneath the coal mine, after analyzing the advantages and disadvantages of active safety technology now, a high precision ranging system based on UWB has been designed. This system uses Symmetric Double Sided Two-Way Ranging algorithm which can reduce the influence of clock drift, improve the ranging accuracy of the system and reduce the false alarm rate of the system. The device has the functions of personnel intrusion alarm, vehicle approach alarm, automatic shutdown of the vehicle, and so on. The results show that the maximum ranging error of the system within 20 m is ±0.13 m, which can fully meet the requirements of vehicle active safety collision avoidance. Through the research and application of preventing intrusion and proximity alarm devices, the collision accidents between vehicles and personnel as well as those between vehicles and vehicles are effectively avoided. The safety of underground personnel is improved, and the efficiency of underground auxiliary transportation is also improved.
