In order to accurately determine the precise location and structure temperature of trackless rubber-tyred vehicle, the positioning system was designed according to the positioning principle of traffic vehicle. platinum resistance was selected as the temperature detection element, and the temperature detection circuit was optimized. After error evaluation, the appropriate temperature of trackless rubber-tyred vehicle structural parts was finally determined. The research of the positioning and temperature detection system of the machine, ensured the safe and stable operation of the underground trackless rubber-tyred vehicle.
