Abstract
The invention discloses a light path structure of a roadside air quality monitoring system, and relates to the field of environment protection technologies. The light path structure comprises a light source, a detector and retroreflectors, wherein the light source 1 emits a monitoring light beam to a first retroreflector 4 through a light path 5, then the first retroreflector 4 reflects the monitoring light beam back to a second retroreflector 3, the second retroreflector 3 reflects the light beam to the first retroreflector 4 again, and finally, the first retroreflector 4 reflects the monitoring light beam to the detector 2, so that an effect of multiple-light-path monitoring is achieved. When the light path structure is used, a host containing the light source 1 and the detector 2 is arranged at one side of a road, the first retroreflector 4 is arranged at the opposite side of the road, and after the light path 5 is adjusted to be aligned at the detector 2, the light path structure can be started to run.
Description
Technical field
The present invention relates to environmental protection technical field, particularly the light channel structure of limit, a kind of road air-quality monitoring system.
Background technology
In the middle of actual production, limit, road air-quality monitoring system normally point type, is pumped into device interior by limit, road air, is completed the detection of dusty gas by the detecting unit of inside, do not detect light path in instrument outside.
The feature of limit, point type road air-quality monitoring system is that structure is simple, inner light path adjustment is comparatively easy, shortcoming is the air owing to only extracting a some position, the pollution level of road can not be reflected comprehensively, particularly affect by meteorological condition, when wind direction blows to road by point type instrument, the truth of roadway pollution can not be reflected completely.
Summary of the invention
Technical matters to be solved by this invention is to provide the light channel structure of limit, a kind of road air-quality monitoring system, adopts open light channel structure, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: the light channel structure of limit, a kind of road air-quality monitoring system, comprise light source, it is characterized in that: the light channel structure of limit, described road air-quality monitoring system comprises the light source being arranged at monitoring system side, light source side is also provided with a detector side by side, this monitoring system also comprises the reflective mirror that two or more vertical ground is installed, No. two reflective mirrors are provided with in the light source side of this monitoring system, a reflective mirror is provided with at the opposite side of this monitoring system, and a reflective mirror is mutually corresponding with the minute surface of No. two reflective mirrors.
Preferably, described light source is for penetrating linear light source.
Preferably, described light source is less than 90 ° for the irradiating angle of a reflective mirror.
Preferably, the length of described No. two reflective mirrors is shorter than a reflective mirror.
Preferably, described detector is spectra collection detector.
The beneficial effect of above technical scheme is adopted to be: 1, the application of this limit, road air-quality monitoring system makes instrument monitoring result more meet the actual conditions of road air quality; 2, this limit, road air-quality monitoring system work is not by the impact of wind direction; 3, this limit, road air-quality monitoring system does not need to adopt the method for electronics can improve detectable signal amplitude, avoiding the shortcoming making electronically to improve signal enlargement range and Noise Synchronization can be brought to amplify, is a kind of effective means improving air quality monitoring signal Sensitivity.

Wherein, 1-light source, 2-detector, 3-No. bis-reflective mirrors, 4-reflective mirror, 5-light path.
Embodiment
The preferred implementation of the light channel structure of limit, a kind of road of the present invention air-quality monitoring system is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the embodiment of the light channel structure of limit, a kind of road of the present invention air-quality monitoring system: the light channel structure of this limit, road air-quality monitoring system, comprise light source 1, it is characterized in that: the light channel structure of limit, described road air-quality monitoring system comprises the light source 1 being arranged at monitoring system side, light source 1 side is also provided with a detector 2 side by side, this monitoring system also comprises the reflective mirror that two or more vertical ground is installed, No. two reflective mirrors 3 are provided with in the light source side of this monitoring system, a reflective mirror 4 is provided with at the opposite side of this monitoring system, and a reflective mirror 4 is mutually corresponding with the minute surface of No. two reflective mirrors 3, light source 1 sends monitoring light beam by light path 5 to number catoptron 4, No. two catoptrons 3 are gone back to through a catoptron 4, No. two catoptrons 3 again by beam reflection to a catoptron 4, finally by a catoptron 4, monitoring light beam is turned back to detector 2 to receive, achieve the monitoring of many light paths.
Composition graphs 1 and Fig. 2, light source 1 is for penetrating linear light source, detector 2 is spectra collection detector, light source 1 is less than 90 ° for the irradiating angle of a reflective mirror 4, the length of No. two reflective mirrors 3 is shorter than a reflective mirror 4, light source 1 passes through the light path 5 of mirror reflection through detector 2 position, and light source 1, detector 2 and No. two catoptrons 3 integrate, and a catoptron 4 is independently.In using, the main frame containing light source 1 and detector 2 is placed on the side of road, a catoptron 4 is placed on the side, opposite of road, and adjustment light path 5 alignment detector 2 just can have been started working.
Above is only the preferred embodiment of the present invention, and it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
