Description
Technical field
The present invention relates to detection field, but be specifically related to a kind of spectral detection rod of continuous coverage.
Background technology
All need gas, liquid isoconcentration composition are monitored and analyzed in many fields such as Chemical Manufacture, environmental monitoring, emission monitorings.Spectroscopic methodology is to carry out a kind of important method that gas concentration is supervised side continuously.In the spectroscopic methodology constituent concentration was analyzed, determinand was measured light then from an end incident of sample cell in sample cell, behind tested gas, go out from the other end transmission of sample cell, enters spectrometric instrument or enters fiber spectrometer by optical fiber.In this surveying instrument, how to arrange light path, make the structure of instrument simple and reliable as far as possible, reducing size and volume is very important for the instrument that is used for site environment, monitoring on the spot.There is following technical matters in prior art: (1) has measurement mechanism now, generally all be that desktop is made by system is desk-top, the medium that detects is placed in the vessel of fixing light path, then vessel are put into the light path intermediate detection, need sampling, be unfavorable for mobile and detection whenever and wherever possible, be difficult to really realize continuous coverage and actual accurate detection, (2) existing measurement mechanism, although the detection of reference light arranged but not do not do the measure of automatic on-line verification for light source intensity and wavelength, (3) since measurement light source work a period of time after, luminous intensity can decay owing to the aging of device, measure out of true so exist, especially can bring very large deviation for the concentration detection.
Summary of the invention
But the object of the invention provides a kind of spectral detection rod of continuous coverage, and this spectral detection rod can directly drop into the tested point of environment to be measured, real-time testing site environment; And increase the compensating action of Spectrum attenuation device, improved measuring accuracy.
For achieving the above object, the technical solution used in the present invention is: but a kind of spectral detection of continuous coverage is excellent, comprise body, be positioned at the glassware pond at body middle part, measurement light source and MMS optical inductor, described glassware pond has the first path channels of passing through for measure spectrum and the second path channels of passing through for reference spectrum, the glassware pond has the groove that can contain determinand in the first path channels, this body front portion forms the first annular seal space by the first bonnet and glassware pond one end, the body rear portion forms the second annular seal space by the second bonnet and the glassware pond other end, described measurement light source is positioned at the first annular seal space, the first convex lens are between measurement light source and glassware pond, described MMS optical inductor is positioned at the second annular seal space, the second convex lens are between MMS optical inductor and glassware pond, one Spectrum attenuation device is positioned at the first annular seal space, this Spectrum attenuation device drives and can switch in light path and two positions of non-light path between measurement light source and glassware pond through the first gear train, one light barrier is positioned at the second annular seal space, and this light barrier drives and can switch in the first path channels light path and two positions of the second path channels light path between described MMS optical inductor and glassware pond through the second gear train.
Further improvement project is as follows in the technique scheme:
1, in the such scheme, described Spectrum attenuation device is fixed proportion Spectrum attenuation device.
2, in the such scheme, described Spectrum attenuation device is between the first convex lens and xenon lamp light emitting source.
3, in the such scheme, described groove is positioned at middle part, glassware pond.
4, in the such scheme, described the first gear train and the second gear train drive and are motor.
5, in the such scheme, described measurement light source is xenon lamp light emitting source or Halogen lamp LED light emitting source.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, but the spectral detection of the present invention's continuous coverage rod can be carried, and detects anywhere or anytime, can directly drop into the tested point of environment to be measured, the real-time testing site environment, and its reliability of the data and authenticity have obtained further raising.
But 2, the spectral detection of the present invention's continuous coverage rod, utilized the demarcation of optical attenuator, the serviceable life in the lamp source that prolongs, reduced the cycle of duplication check, improved accuracy in detection, intensity and reference spectrum comparing calculation that measurement light source is accepted spectrum by detection zone by MMS spectrum inductor are finished the measurement on whole spectrum road, calculating thus projection light is passing through between detection zone by the element of Absorption of Medium, the spectrum rod, the compensating action of increase Spectrum attenuation device has improved measuring accuracy.
But 3, the spectral detection of the present invention's continuous coverage rod, increased the light source detection attenuator, because the kill mechanism of lamp source after long-term the use, generally all be to follow the lamp source of changing in the certain hour cycle, in fact exceeding the time limit and can use in a lot of lamp sources, can't know exactly how many impacts are the degree of lamp source decay bring with decay is rear to measurement, the mechanism of the lamp source attenuation compensation that increases by the present invention, prolonged the serviceable life in lamp source, reduce cost, and during normal use owing to the light source attenuation process is constantly compensated the accuracy of the detection that further improves.
