In order to accurately apply thermal imaging camera to capture the temperature of a truck brake in motion on the roadside, this paper investigates the factors affecting the collection of brake temperature measurement based on the principle of temperature capture by thermal imaging camera and the structural characteristics of truck brakes. Through real vehicle experiments in the static wheel idling braking conditions using thermal imaging cameras and thermocouples two ways to collect brake drum temperature data, thermocouple readings as true brake drum temperature, the study of the thermal imaging camera under different erection distance, erection height of the impact of the brake temperature detection of trucks, and based on the road conditions and the facilities along the road set up conditions gives a reasonable range of erection distance, height. On this basis, the brake temperatures of four different speeds were collected by using a 49t fully loaded truck on an actual long downhill section to analyze the influence of different vehicle operating speeds on brake temperature measurement. The results show that: (1) thermal imaging camera set up position from the wheel 1-8m, set up height from the ground 0-1.5m, the brake temperature measurement has no significant effect; (2) long downhill section of the vehicle driving speed in the 60km / h ~ 80km / h, the brake temperature measurement has no significant effect, the driving speed in the 80km / h ~ 90km / h, the brake temperature of the camera detection (3) The three factors of erection distance, height and vehicle traveling speed in the erection height is the main influencing factor, the influence of the three on the thermal imaging camera to detect the brake temperature is independent, that is, in the process of practical application can be free to adjust the erection position within the range of no influence.
