Description
Technical field
It is the invention belongs to automobile emission gas analyzer technical field more particularly to a kind of motor-driven based on NDIR and diffusing reflection technology
Tail gas remote-measuring equipment.
Background technology
As China's vehicle emission standards are progressively upgraded, the various emission from vehicles levels travelled on road will
There is a big difference.Pollution of the automotive emission to ambient air quality is effectively reduced, the vehicle of maximum discharge is found and administer,
It is very important for improving urban air-quality situation.
The main behave of control automobile pollution at present is motor-vehicle tail-gas annual test and daily road inspection and patrols and examines, but reality
Many problems are still present in detection process：Traditional detection method is contact measurement, motor vehicle exhaust is sampled, then
Be analyzed with conventional instrument, waste time and energy, high cost, operation difficulty it is big, 4 staff can only detect more than 100 in one day
Car, the purpose of screening high pollution car is not reached much.
The Double idle state method detection method drawback for being used is more, its testing result can not comprehensively, to accurately reflect motor vehicle true
Real emission status.Artificial property is strong in detection process, and the chance of cheating is left to carburetor car.Testing index is single, can only
Measurement carbon monoxide (CO), the concentration of emission of hydrocarbon (HC), and the discharge that cannot measure nitrogen oxides (NOx) is dense
Degree；Operating condition method detection, it is necessary to tested vehicle is marched into the arena, detection efficiency is low, much can not meet the requirement of real-time detection.
The main method for using at present is to set up portal frame in runway, places light source and receiver, places anti-on road surface
Mirror is penetrated, reflective installation method is used to bicycle road, although this method can be realized to one-lane measurement, road reflection
Mirror is highly prone to the pollution of flue dust, rainwater and other pollutants, and measurement result authenticity is poor；Another method is using to penetrating
Method, light source and receiver are placed in both sides of the road respectively, but this kind of mode can only be directed to and accommodate the list that a motor vehicle passes through
Track road conditions are measured, and application is restricted.
The content of the invention
It is a primary object of the present invention to overcome the shortcomings of above-mentioned technology, and provide a kind of based on NDIR and diffusing reflection technology
Telemetering motor vehicle tail equipment, improve monitoring efficiency.
The present invention to achieve the above object, using following technical scheme：It is a kind of motor-driven based on NDIR and diffusing reflection technology
Tail gas remote-measuring equipment, including Tail gas measuring unit, candid photograph detection triggering system, arbitrary source；
The arbitrary source is used to launch the mid-infrared light after modulation, is made in spatial domain full of uniform using irreflexive form
Infrared light；
The Tail gas measuring unit, tail gas remote unit is converged at by the plano-concave lens of Tail gas measuring unit front end, when
The exhaust smoke group discharged by vehicle is appeared in when in light path, changes the light path intensity of infrared light, is realized to discharge gas
Detection；
It is described to capture detection triggering system, when vehicle snapshot detection triggering system detectio road has carrys out car, vehicle is believed
Breath is sent to tail gas remote unit by transmission line, and it is whole that the exhaust information and information of vehicles that remote unit will be detected carry out data
After closing superposition, through data transmission interface, center control platform is transferred to by transmission network.
Preferably, the Tail gas measuring unit and arbitrary source are installed at the crossbeam above road, using the shape shot downward
Formula.
Preferably, the Tail gas measuring unit and arbitrary source are installed on the both sides of runway, in the form of to penetrating.
The beneficial effects of the invention are as follows:Relative to prior art, on the premise of normal vehicle operation is not influenceed, to vehicle
Exhaust emissions situation make detection.Equipment overcomes current remote sensing equipment and cannot realize that the accurate detection in multilane section is asked
Topic so that the independent detection simultaneously of multilane is possibly realized.Because infrared light supply uses irreflexive form, Tail gas measuring equipment light
Road is in divergence form, and can be installed using formula of shooting downward can also be installed using correlation, at the same can real-time monitoring vehicle flowrate, it is and traditional
Easily there is Monitoring Data mistake and compares when vehicle increases in parallel light path, and accuracy of detection is not only increased simultaneously using diverging light path
Many parallel vehicles can be monitored, makes monitoring efficiency higher, equipment can be installed and used under the conditions of various roads, improve application
Popularity.

Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the invention in detail.
As shown in figure 1, being principle schematic of the invention.A kind of telemetering motor vehicle tail equipment includes 1 Tail gas measuring list
Unit and 2 arbitrary sources.Design principle is based on NDIR technologies, and using irreflexive form, installation and debugging are flexible, Tail gas measuring unit
At the crossbeam that can be installed on above road with arbitrary source, in the form of shooting downward, it is also possible to be installed on the both sides of runway,
In the form of to penetrating.Mid-infrared light after the transmitting modulation of 2 arbitrary sources, is made in spatial domain full of uniform using irreflexive form
Infrared light.When 11 vehicle snapshots detection triggering system detectio road has carrys out car, information of vehicles is sent by 13 transmission lines
Tail gas remote unit is given, after the Vehicular exhaust information superposition that remote unit will be detected to the information of vehicles captured, through 14 data
Coffret, center control platform is transferred to by 3 transmission networks.
As shown in Fig. 2 being detects schematic diagram of the invention.A kind of telemetering motor vehicle tail equipment, it is unrestrained due to using
The form of reflection, the infrared light launched by 2 arbitrary sources be spatially towards all directions, it is equally distributed, and
The light path in track is detected, 12 tail gas remote units are converged at by the plano-concave lens of 1 Tail gas measuring unit leading portion.When by car
The exhaust smoke group discharged is appeared in when in light path, light path intensity is changed, so as to realize the detection to discharge gas.And it is interior
Portion's design reference reference channel, can filter out the influence of environmental gas factor, make measurement data more accurate.
The present invention uses irreflexive form, has broken the constraint of traditional form, and light source and detector installation form are flexible,
Testing result is small by ectocine.By setting up tail gas remote-measuring equipment, the exhaust emissions situation of the current vehicle of monitoring identifies tail gas
Exceeded vehicle, between automobile industry development and environmental protection, seeks new balance, to solve asking for motor vehicle exhaust emission pollution
Topic seeks new countermeasure.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
