Title:
METHOD FOR DETECTING BEARING TEMPERATURE OF RAILWAY PASSENGER TRAIN AND DIGITAL/ANALOG INTEGRATED TEMPERATURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/024185
Kind Code:
A1
Abstract:
A method for detecting a bearing temperature of a railway passenger train. Digital and analog temperature measuring chips are integrated inside a sensor probe (1); the two temperature measuring chips detect the temperature of an axle box at the same time and transmit temperature signals to a detection host by means of transmission lines; the detection host receives the two temperature signals sequentially and independently performs a determination on the two signals; then the two temperatures are selected according to a temperature selection condition, and a temperature is finally selected to be displayed and analyzed. The use of the method for axle temperature detection can yield more reliable and higher beneficial effects than a previous single sensor detection method. Also disclosed is a digital/analog integrated temperature sensor used for the method.
