Abstract

The invention provides a tail gas light obscuration remote-measuring system and a light path arranging structure. The tail gas light obscuration remote-measuring system comprises a controller and thelight path arranging structure; the light path arranging structure comprises a light source, a reflection device and a receiving detector; the reflection device comprises an emergent light reflectionstructure; the emergent light reflection structure comprises a first motor and a group of reflecting mirrors driven by the first motor; the first motor drives to adjust angles of the reflecting mirrors, so that a light path can be adjusted at will, and penetrates through a part near a vehicle exhaust port; tail gas is measured when just being discharged, so that measurement result accuracy is high; the light source and the receiving detector are arranged above a lane, so as not to occupy the lane, so that vehicle traffic cannot be affected, light obscuration of the tail gas can be monitored under the condition that car owners are not informed, cars are automatically detected, labor cost is reduced, multiple lanes can be monitored at the same time, and multiple cars are mutually unaffectedwhen passing through the multiple lanes at the same time.

Description

technical field [0001] The invention relates to the technical field of tail gas detection, in particular to a remote measurement system for tail gas opacity and an optical path setting structure. Background technique [0002] In the prior art, the remote measurement of the opacity of motor vehicle exhaust mainly includes three methods. 1. The portable smoke meter is the most accurate in measuring the opacity of exhaust gas, but its disadvantage is that it must be detected at a designated detection point, which affects the normal operation of the vehicle. Driving, the detection efficiency is low, and labor costs are required, and human intervention is inevitable; 2. The horizontal telemetry equipment is slightly accurate in positioning the exhaust pipe, but its disadvantages are only applicable to a single vehicle passing through, and two or more vehicles passing through at the same time , cannot be distinguished. ; 3. Vertical telemetry scheme. Currently, the existing verti...
