Problems solved by technology

[0003] The temperature test paper method needs to manually paste the temperature test paper on the axle box. After the train runs each time, the color of the test paper is manually observed one by one. Since there are many axle boxes on the train, this method makes the labor intensity of the inspectors very high, and the efficiency is very high. In addition, this method can only detect the temperature in the area where the temperature test paper is pasted, and the detection range is small

Abstract

The invention provides a following type subway train axle box temperature detection system and method. The axle box temperature is detected through arranging a main controller as well as a speed measurement device for measuring the marching speed of a train and a follow-up imaging device which are arranged in sequence in the marching direction of the train, and the following type subway train axlebox temperature detection system is arranged on a train operation line. According to the following type subway train axle box temperature detection system and method, the train axle box temperature is automatically detected when the train passes, manpower is liberated, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a system and method for detecting the temperature of an axle box of a follow-up subway train. Background technique [0002] During the operation of the subway train, when an abnormality occurs inside the axle box, the frictional resistance between the wheel and the axle will increase, and the temperature of the axle box will rise. If it is not handled in time, it will bring safety hazards to the train operation. At present, the commonly used method is to use the temperature test paper method to detect the temperature change of the axle box. This method pastes the temperature test paper on the axle box of the train. A series of squares or dots are arranged on the temperature test paper to represent different temperatures. When testing When the temperature of the point is greater than the temperature of the point, the color of the square or dot becomes irreversibl...
