Abstract
The utility model relates to a device which can be positioned on both sides of roads and accurately test tail gas from motor vehicles. The utility model solves the problem that the utility model provides a smoke tester for tail gas from different motor vehicles applicable to various heights of exhaust pipes. The utility model is characterized in that a launcher and a receiver are both upright type cylinder-shaped. The launcher is uniformly distributed with more than two laser point light sources and collimating mirrors corresponding to the point light sources. The receiver is correspondingly provided with more than two collecting mirrors and detectors corresponding to the collecting mirrors. The utility model skillfully applies light sources in cylinder-shaped distribution, covers the majority of exhaust pipes for motor vehicles and enhances measuring accuracy.
Description
Technical field
The utility model relates to and places road two sides, accurately measures the device of passing vehicular emission exhaust gas smoke (penetrability).
Background technology
Traditional motor-vehicle tail-gas smoke measurement method has two kinds: a kind of is filter paper smoke intensity method; Another kind is to adopt a side to launch a light source beam, and opposite side receives this bundle and absorbed by flue dust and the light source that causes light intensity decreasing, i.e. penetrability mensuration, and the device of using this measuring method has two kinds, and a kind of is to adopt the static measurement method that flue gas suction air chamber is detected; Another kind is the telemetry that equipment is placed road two sides monitoring vehicular traffic discharging flue gas.
The measuring principle of filter paper smoke intensity method is to utilize a kind of device, from the diesel engine truck exhaust pipe, extract the exhaust of a constant volume out, make it by a white filter paper, the charcoal cigarette of waste gas remains on the filter paper, it is black that filter paper is dyed, with the blackness that dyes of detection means measure filter paper, promptly represent the exhaust smoke of diesel vehicle then.The blackness that dyes of filter paper is permitted unit representation with the 0-10 ripple, and the ripple unit of being permitted of regulation white filter paper is 0, and the ripple unit of being permitted of black filter paper is 10 entirely, from evenly distributing between the 0-10.Filter paper smoke intensity method is a kind of static measurement method, needs to stop to measure, and efficiency of measurement is very low.
The penetrability mensuration adopts a pair of photoelectric sensor light path, and a side is launched a light source beam, and opposite side receives this light source beam.The measurement of need stopping of static degassing method, efficiency of measurement is the same low with filter paper smoke intensity method.Existing telemetry can not adapt to the different vehicle of various gas outlet height owing to be the spot measurement that a light path is only arranged, poor practicability, and also existing instrument is to combine with the tail gas telegauge, sensor bulk is big, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is: provide a kind of multiple spot light path to measure, can adapt to the pick-up unit of the different motor-vehicle tail-gas smoke measurement of various gas outlet height.
The technical solution that realizes the foregoing invention purpose is as follows:
Motor-vehicle tail-gas smoke intensity pick-up unit comprises transmitter, receiver and computing machine, and described transmitter comprises LASER Light Source and the collimating mirror corresponding with light source, and described receiver comprises condenser and the detector corresponding with condenser, it is characterized in that:
Described transmitter, receiver are the vertical type column, and height is greater than 120mm; Uniform plural laser spots light source and the collimating mirror corresponding on the described transmitter with pointolite, corresponding plural condenser and the detector corresponding of being provided with on the described receiver with condenser.
Motor-vehicle tail-gas smoke intensity pick-up unit according to above-mentioned is characterized in that: described transmitter, receiver are the vertical type column, and height is greater than 120mm; Described transmitter is provided with the lasing area light source of a height more than 100 millimeters, corresponding plural collimating mirror, corresponding plural condenser and the detector corresponding with condenser of being provided with on the described receiver of being provided with area source.
The utility model has used a light source that becomes column to distribute cleverly, covered most motor vehicle exhaust height, can obtain the measurement result of a vertical profile distribution index of passing motor-vehicle tail-gas smoke emission, penetrability is divided into 100 grades, has improved measuring accuracy.The utility model is simultaneously speed, acceleration and the length of measuring machine motor-car also, realizes license plate for vehicle identification simultaneously.Have high precision, real-time, advantage that monitoring efficient is high.
