Abstract

The invention provides a vehicle axle multi-point temperature measuring device and method based on infrared multiple spectrums. The device comprises an infrared multi-spectral sensor set and a spectral thermometer. The infrared multi-spectral sensor set comprises a plurality of distributed infrared multi-spectral sensors. Each infrared multi-spectral sensor is used for collecting infrared multi-spectral radiation intensity data of a single target point on the axle surface of a vehicle. The spectral thermometer is used for obtaining the temperature of each target point according to the multi-spectral radiation intensity data of each target point. Through the high-speed measurement of the infrared multiple spectrums and multiple target points, the device and method in the invention achievesthe high precision measurement of the axle temperature of a sports car, are suitable for the non-contact online measurement of the multi-point area temperature under axle surface emissivity unknown orvariable surface emissivity conditions, and overcome the problem that the existing axle radiation temperature measurement technology is limited by the unknown surface emissivity and the limitation problem of temperature distribution measurement.

Description

technical field [0001] The invention relates to the technical field of vehicle axle temperature measurement, and more particularly, to a multi-point temperature measurement device and method for vehicle axles based on 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 transit operating equipm...
