Abstract
The utility model relates to an on-line monitor for visible light reflectivity and transmittivity of building glass, which is characterized in that the spectrum of a pulse modulation visible light source is ranged from 380nm to 780nm. The modulation light from the pulse modulation visible light source is output in two bunches of light through a light splitter. One bunch of light vertically shines on a measured glass face and forms a transmission light through the glass face. The other bunch of light has an angle which is ranged from 5 degree to 10 degree with the normal line of the measured glass face and forms a reflex by shining. The transmission light and the reflex are separately received by a light integrator and changed into electrical signal through a photoelectric converter 4 and a photoelectric converter 6, and then the electrical signal is processed by a signal processing system 7 and outputs the transmittivity and the reflectivity of the measured glass. The utility model can measure on-line reflectivity and transmissivity of building glass in visible light and can continuously work for 24 hours. The utility model is of reasonable design, convenient use, lower cost and distinctive economy benefit.
Description
The utility model relates to a kind of optical detection instrument, particularly relates to a kind of building glass visible reflectance and transmissivity on-line monitoring instrument.
Along with the fast development of glass industry and glass deep processing and the raising of living standards of the people, the use of building glass is not only for daylighting, also in order to decorate.The demand of building glass is more and more, and corresponding glass production amount also increases day by day.At present, nearly more than 300 of domestic construction glass production line, millions of square metres of year outputs are for guaranteeing the quality of glass production, construction sector of country has formulated corresponding standard GB/T-2680-94, JC693-1998 to building glass at visible region transmitted light and reflected light.Owing to there is not online detection instrument, still adopt off-line checking method at present, the glass sample that is about to produce is transported to national glass inspection center and detects, and when sample is defective, this a collection of product all will become waste product.Therefore, owing to can not in time take the effective technology measure, and cause the great amount of manpower and the wasting of resources.
The utility model purpose is to provide a kind of building glass visible reflectance and transmissivity on-line monitoring instrument, and it is reasonable in design, easy to use, cost is low, but and continuous working 24 hours.This instrument comes into operation, and can avoid occurring substandard product in batch, has remarkable economical and social benefit.
This building glass visible reflectance and transmissivity on-line monitoring instrument, comprise pulsed modulation visible light source 1, optical splitter 2, light integrators 3,7, photoelectric commutator 4,6 and signal Processing and display system 5 compositions, it is characterized in that: pulsed modulation visible light source 1 is arranged on the top of tested glass 8, its light modulated of sending is exported two-beam behind optical splitter 2, the tested glass of wherein a branch of smooth vertical irradiation forms transmitted light through after the glass; The normal of the tested glass of another Shu Guangyu becomes 5～10 ° of (by the GB-2680 regulation) irradiation backs, angle to form reflected light; Transmitted light and reflected light are received after photoelectric commutator 6,4 becomes electric signal by light integrators 7,3 respectively, handle the transmissivity and the reflectivity of the tested glass of output again through signal processing system 5, and the spectrum of pulsed modulation visible light source is 380～780nm.
Drawings and Examples:
Fig. 1: building glass visible reflectance and transmissivity on-line monitoring instrument structural representation
Fig. 1 is disclosed to be an embodiment (see figure 1) of the present utility model, pulsed modulation visible light source 1, optical splitter 2, light integrators 3 are arranged on the top of tested glass, light integrators 7 be arranged on optical splitter 2 under, said apparatus and photoelectric commutator 4,6 are mounted on the production line, signal Processing and display system 7 can be installed on the production line, also can be installed in the pulpit.The spectrum of pulsed modulation visible light source is 380～780nm.
This monitor is simple in structure, easy to operate, can on-line measurement, but and continuous working 24 hours.
