Description
Technical field
This utility model belongs to aeromerric moasurenont technical field, particularly relates to and short range visibility meter light source power is tested device.
Background technology
Atmospheric visibility, also known as visual range, refers to that twenty-twenty people can see and recognize the maximum horizontal range of object under weather condition at that time from sky background, is a kind of important attribute of air, often refers in daily life.Atmosphere visibility meter is the measurement instrument of light, mechanical, electrical combination, and it is made up of discharger, reception device, cross arm bracket etc..The discharger of visibility meter is using infrared LED as light source, sample space it is irradiated to after pulse modulated, light is produced scattering by the atmospheric particles in sample space, it is positioned at the scattered beam fixing scattering angle on discharger and reception device isoplanar and is irradiated on photodetector, after amplifying and changing with A/D, CPU is converted into atmospheric optics visibility by dedicated algorithms.
Infrared LED light source power concordance in visibility meter discharger, reliability directly influence visibility meter certainty of measurement, and infrared LED light source power test screen is particularly important.Infrared LED light source power test device is the effective means of raising visibility meter product quality.Owing to short range visibility meter has miniaturized structure feature, in prior art, the discharger infrared LED test of light source device of the visibility meter (long range visibility meter) of maximum range 50km cannot meet its requirement.
Utility model content
The technical problems to be solved in the utility model is that existing infrared LED test of light source device is only applicable to long range visibility meter, the test request of the light source power of short range visibility meter cannot be met, a kind of short range visibility meter light source power test device is provided for this.
The technical solution of the utility model is: short range visibility meter light source power test device, it includes the first scissors type lifting platform, the second scissors type lifting platform and the energy meter that linearly interval disposes, described first scissors type lifting platform carries light source assembly installing plate, described light source assembly installing plate carries LED light source component, carrying the optical lens receiving the directional light sent by LED light source component and the probe being positioned at optical lens focal position on described second scissors type lifting platform, described probe is connected with energy meter by transmission cable.
LED light source component described in such scheme includes LED light source component lens barrel, is fitted with light source assembly optical lens, lock-screw and infrared LED in described LED light source component lens barrel.
The beneficial effects of the utility model apply to the test of short range visibility meter light source power, by infrared LED light source power test screen, rejecting defective infrared LED light source from source, reach raising visibility meter product quality purpose.For short range visibility meter discharger miniaturization feature, in conjunction with short range visibility meter manufacturing technique requirent, accomplish at design aspect: rational in infrastructure, simple to operate, installation and easy to adjust, good stability.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram；
Fig. 2 is the schematic diagram of LED light source component in Fig. 1；
In figure, 1, LED light source component, 2, light source assembly installing plate, the 3, first scissors type lifting platform, 4, optical lens, the 5, second scissors type lifting platform, 6, probe, 7, energy meter, 8, LED light source component lens barrel, 9, light source assembly optical lens, 10, lock-screw, 11, infrared LED.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1 and Figure 2, this utility model includes the first scissors type lifting platform the 3, second scissors type lifting platform 5 and energy meter 7 that linearly interval disposes, described first scissors type lifting platform carries light source assembly installing plate 2, described light source assembly installing plate carries LED light source component 1, carrying the optical lens 4 receiving the directional light sent by LED light source component and the probe 6 being positioned at optical lens focal position on described second scissors type lifting platform, described probe is connected with energy meter by transmission cable.
LED light source component is arranged on the first scissors type lifting platform by light source assembly installing plate.Probe and the second scissors type lifting platform are arranged on another scissors type lifting platform (can be referred to as the 3rd scissors type lifting platform).Optical lens is fixed on the second scissors type lifting platform.Regulate LED light source component, optical lens, probe axis height by first, second scissors type lifting platform, make three's axis be positioned at sustained height.Refer again to the distance that eyeglass focal length is determined between three.Certain this utility model can also omit the 3rd scissors type lifting platform, only regulates LED light source component, optical lens, probe axis height with first, second scissors type lifting platform.This utility model can be placed in same light source power detection platform, it is ensured that smoothness of the present utility model.
Short range visibility meter transmitting terminal (containing light source assembly) the light source assembly optical lens 9, lock-screw 10 and the infrared LED 11 that assemble are loaded LED light source component lens barrel 8, switch on power, open energy meter, constantly test and finely tune energy meter probe, distance between eyeglass and lens barrel three, until light source power measured value meets instructions for use, with lock-screw locking mechanism part, so far light source power detection platform has been debugged.
LED light source component being arranged on the light source power detection platform debugged, switches on power, infrared LED sends a light beam.Point light beam is directional light through LED light source component internal optics lens transformation.Directional light is converged to a light beam through optical lens secondary, and the probe being positioned at optical lens focal position converts optical signals to the signal of telecommunication, receives energy meter through transmission cable, thus measuring the power of infrared LED pipe.
By to infrared LED light source power test screen, rejecting defective infrared LED light source from source, reach raising visibility meter product quality purpose.
