Abstract

The invention provides a vehicle axle single point temperature measurement device and method based on visible light and infrared multi-spectrum. The device includes an infrared multi-spectral sensor,a linear array visible light sensor and a spectral thermometer. The linear array visible light sensor is used for scanning a target region of a target point whose temperature is to be measured on thesurface of a vehicle axle and obtaining a visible light image of the target region. The infrared multi-spectral sensor positions the target point whose temperature is to be measured based on the visible light image of the target region and collects infrared multi-spectral radiation intensity data of the target point. The spectral thermometer is used for processing the infrared multi-spectral radiation intensity data to obtain the temperature of the target point. The measurement way combining infrared multi-spectral measurement with visible light imaging measurement is adopted. Through the measurement of infrared multispectral radiation intensity of the target, the temperature of the target point on the surface of the axle is measured. The temperature measurement target point of the axle ispositioned in real time through visible light imaging under the illumination of an active light source.

Description

technical field [0001] The invention relates to the technical field of vehicle axle temperature measurement, and more particularly, to a single-point temperature measurement device and method for vehicle axles based on visible light and infrared multi-spectrum. Background technique [0002] Urban rail transit is the main line of urban public transportation and the lifeline project of the city. my country's urban rail transit is developing rapidly. As of 2016, a total of 30 cities across the country have opened rail transit lines. Urban rail transit has a large passenger flow and concentrated personnel, and the consequences and impacts of failures will be very serious. The operation safety of urban rail transit is an important part of urban public safety. The substantial increase in the operating mileage of rail transit and the increase in passenger flow have brought great pressure to the safety of rail transit operation, which will also affect the nature of urban rail trans...
