For problems of incorrect ranging caused Sports Bra by interference and high cost of existing collision avoidance system of mine locomotive, a collision avoidance and ranging system of mine locomotive based on laser ranging was designed by use of STC90C516RD+ single chip microcomputer and TDC-GP1 timing chip with high precision.Ranging principle of the system and design schemes of software and hardware were introduced.Ranging test was done for the system Herbs in range of 20-100 m with the max original ranging error of 0.22 m.

After being linearly fitted and corrected in Matlab by use of the least square method, ranging errors were less than 0.03 m and satisfied ranging requirement at locomotive running.
