在长大坡道设红外线探测点,因列车持续制动,车轮踏面及轮心的温度将高于轴箱温度,若仍按非制动区的一般要求来测轴温,则探测器无法区别车轮踏面、轮心和轴箱的温度,致使探测器无法使用。我们西安局的铁路区段大部分为长大坡道,为了让探测器在长大坡道区段也能使用,必须克服干 Infrared detection point in the growing up of the ramp, due to train continuous braking, wheel tread and wheel center temperature will be higher than the temperature of the axle box, if still according to the general requirements of non-brake zone to measure the shaft temperature, the detector can not be distinguished Wheel treads, wheel center and axlebox temperatures make the detector unusable. Most of the railway sections of our Xi’an Bureau are up-ramps, and in order to allow the detectors to be used in the up-ramp sections, we must overcome
