Vehicle wheel shaft multi-point temperature measuring device and method based on visible light and infrared multi-spectrum

Abstract

The invention provides a vehicle wheel shaft multi-point temperature measuring device and method based on visible lights and infrared multi-spectrum; the device comprises an infrared multi-spectrum sensor set, a linear array visible light sensor and a spectrum thermometric indicator; the linear array visible light sensor is used for scanning target areas to which to-be-tested temperature target points are located on a vehicle wheel shaft, thus obtaining visible light images of target areas; the infrared multi-spectrum sensor set comprises a plurality of infrared multi-spectrum sensors arrangedside by side; each infrared multi-spectrum sensor is used for locating a single to-be-tested temperature target point according to the target area visible light image, and gathering the infrared multi-spectrum radiation intensity data of said target point; the spectrum thermometric indicator is used for obtaining the temperature of each target point according to the infrared multi-spectrum radiation intensity data gathered by the infrared multi-spectrum sensor set. The method uses the visible light images under active light source irradiation to locate the wheel shaft temperature measurementpoint targets in real time, and uses the infrared multi-spectrum to realize multi-point target high speed non-contact temperature measurements.

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 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 transi...
