Description
Technical field
The present invention relates to safety in the work such as a kind of deep-sea illumination apparatus is surveyed under water, underwater prospecting and the detection evaluation measures of validity, be specially the detection platform of effective working distance under water of deep-sea illumination apparatus, can detect quickly and accurately light fixture at the effective working distance of specifying under light intensity in limited space, be particularly useful for the underwater operating distance of deep-sea illumination apparatus and detect.
Background technology
The deep-sea illumination apparatus is dived under water and is played very important effect in the work of device, is the prerequisite of carrying out the underwater optics imaging, also provides necessary guarantee for undersea detection, underwater prospecting.
At present, the detection technique of illumination apparatus only is confined to the detection to the light source of land use.Because the decay that light is propagated in air is less obvious, so the effective working distance of illumination apparatus detects effect and not obvious in the field of daily productive life.Yet underwater lighting equipment, especially the deep-sea illumination apparatus is operated in seawater, water body has strong absorption and scattering process to visible light, therefore the operating distance of illumination apparatus at the deep-sea is greatly limited, this is the significant difference of deep-sea illumination and land illumination, also proves the present invention---and the detection platform of effective working distance under water of deep-sea illumination apparatus is being significant aspect guarantee undersea detection, underwater prospecting work safety and validity.
In the illumination detection field, coherent detection authority file about land light fixture has been tending towards perfect, especially in LED and solid-state illumination field, the CIE_127-2007 standard of existing International Commission on Illumination (CIE) issue, the LM-79-08 of North America illumination association (IESNA) issue, IESNA LM-80-08 standard be as authority's detection standard, and be domestic also just like a series of detection national standards of GB/T 5700-1985, GB/T 3978-1994, GB 15039-1994.
Yet at home, the patent of existing disclosed illumination context of detection does not all relate to correlation technique and equipment about the operating distance that detects the underwater lighting equipment, and this detection platform will be filled up this blank.
In theory, if the attenuation coefficient of known luminaire outgoing intensity, water body, propagation distance, beam divergence angle just can calculate the interior luminous flux of unit area under water, with threshold, draw the operating distance of illumination apparatus.But this way need to be measured a large amount of physics and geometric parameter, and is lengthy and jumbled and loaded down with trivial details in actual measurement, and precision also is restricted.
Summary of the invention
In order to detect the underwater operating distance of deep-sea illumination apparatus, and overcome above shortcoming, the invention provides a cover detection platform, can detect fast, accurately, intuitively the effective working distance of deep-sea illumination apparatus, and can require according to the specific works of environment and light fixture to adjust flexibly.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The detection platform of effective working distance under water of deep-sea illumination apparatus is comprised of tank, track type all position mobile system, ten shadow shields, four reflectors, illumination apparatus fixture, phase machine clamp, steering wheel and cameras, and configure a computing machine as reception, analysis and the end for process of output terminal and the detection signal of control signal, it is characterized in that: the track type all position mobile system is mobile to detect the effective working distance under water of deep-sea illumination apparatus in the fold-line-shaped light propagation ducts that camera is being made of shadow shield and reflector.
Beneficial effect of the present invention:
1. the image information of obtaining by the Computer Analysis camera draws tested deep-sea illumination apparatus at the illuminating effect of relevant work distance, thereby can draw fast, accurately, intuitively effective working distance according to illuminating effect.
2. camera is connected with the support that can arrive any point in measured illumination apparatus light path plane with stepper motor, can design on request the light intensity sampling spot on light path by control circuit, realizes that robotization accurately measures.
3. can obtain the attenuation function of light intensity propagation distance by computer fitting according to the light intensity data of a plurality of sampling spots, thus the counter illuminating effect of releasing any distance.This process does not need the isoparametric measurement of the attenuation coefficient of beam divergence angle, water.
4. by catoptron, light is propagated along broken line, neither lost the floor area that propagation distance has reduced again measuring table, be convenient to obtain the deep-sea light fixture at the experiment effect of telecommute state in limited space.
