The basic role of reflecting material is the irradiation by automotive headlight, uses its retro-reflective properties that the means of transportation loaded information effectively is delivered in driver and crew's organs of vision, thereby improves the visibility at night of facility.
Reflecting material is widely used in transportation industry, mainly uses in traffic safety facilitieses such as traffic sign, pavement strip, protuberant guide post, has vital role to ensuring traffic safety.Reflecting material and facility use larger in highway construction, are the key factors that influences the traffic engineering quality.
Protuberant guide post is to be fixed in the raised indicia piece that plays the graticule effect on the road surface, can be used to mark subtend driveway separatrix, driveway separatrix, driveway edge line etc. in the same way.Protuberant guide post whenever prolongs kilometer and uses about 300 in expressway construction, by the end of the year 2008,0.64 ten thousand kilometer of newly-increased highway is through estimating that only expressway construction in 2008 uses nearly more than 200 ten thousand of protuberant guide post approximately.Reflecting material and facility that a large amount of similar projections road signs is such are applied in the highway construction, its quality level height has badly influenced the engineering construction integral level, and therefore the effective evaluation to reflecting material and facility quality is extremely important work of current traffic specialty.
Whether reliably the reflex reflection performance is the quality most critical technical indicator of investigating reflecting materials such as graticule, in the research of material, produce, sell and use and each link of maintenance all is to weigh the primary factor of its optical property.Therefore, measurement is the most direct and effective means that reflecting material (facility) performance is estimated to retro-reflecting coefficient.Therefore, whether qualified the test of traffic marking retro-reflecting coefficient just become one of traffic marking quality the test index that concerns, so the measuring technique of retro-reflecting coefficient requires very high.
The composition of reflex reflection measurement standard device:
Reflex reflection measuring unit, sample rest area, standard A light source, incident angle regulator, view angle regulator and control system etc.
Protuberant guide post sample in this device directly is positioned in the sample rest area, and sample both can't have been fixed and angle rotation in accordance with regulations when its shortcoming was to measure, and also inconvenient controlling level degree, verticality can not guarantee light source and sample center-aligned.
The present invention has provided the attachment device that a kind of protuberant guide post retro-reflecting coefficient is measured, sample rest area corresponding to the absolute method measurement, characteristic and reflex reflection Testing requirement at protuberant guide post, play guaranteeing protuberant guide post sample measurement process stability, the consistance during the angle rotation in accordance with regulations, and controlling level degree, verticality and effects such as assurance light source and sample center-aligned.
