Abstract

The invention provides a motor vehicle tail gas remote sensing detection system calibrating device and a motor vehicle tail gas remote sensing detection system calibrating method applying the same. The motor vehicle tail gas remote sensing detection system calibrating device comprises a random gas inlet unit, a main gas chamber, a control unit and a display recording unit, wherein the random gas inlet unit comprises a plurality of gas inlet cylinders, common tail gas with different components is stored in each gas inlet cylinder, and the control unit can randomly select part of the gas inlet cylinders to inflate the main gas chamber so as to simulate different types of tail gas. According to the motor vehicle tail gas remote sensing detection system calibrating device and the calibrating method, through a random gas inlet mode, the situation that a motor vehicle tail gas remote sensing calibrating system manufacturer influences a calibration result through a technical means is avoided,and the calibration accuracy and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection verification equipment, in particular to a verification device and method for a motor vehicle exhaust remote sensing detection system. Background technique [0002] The remote sensing detector for exhaust gas detection is a measuring device that directly measures the concentration of automobile exhaust gas according to the long-distance photometric changes caused by automobile exhaust pollutants. It has the advantage of not affecting the normal driving of the car. Its basic working principle is: The host of the instrument emits a beam of infrared (ultraviolet) light across the road. When the car passes by, the spectral intensity and characteristics of the red (ultraviolet) light received by the receiving end will change. This change indicates the gas to be measured (such as : CO, CO2, HC, NO) concentration. [0003] Because the exhaust gas remote sensing detector has high require...
