Abstract
The utility model discloses a high-density infrared-ray elevator light curtain which comprises a power supply module, a controller, an emitter and a receiver, wherein an output end of the emitter is provided with optical gratings. By using the high-density infrared-ray elevator light curtain of the utility model, triggering dead zones can be greatly reduced and thus safety of passengers can be better protected.
Description
Technical field
The utility model relates to a kind of high density infrared ray elevator light curtain.
Background technology
Elevator light curtain is the safety device that prevents from clamping when Automatic door of elevator from closing passenger or goods.It utilizes the high-velocity scanning of many group infrared emission and receiving element; survey the shelter in the protection zone and provide signal to upper control convenience; existing market glazing curtain light pipe spacing is all greater than 55mm; and the passenger can remove the shading light curtain with hand when entering elevator; the width of children's hand is generally all less than 45mm; so can't stop easily the light curtain, occur by the situation of tong.
The utility model content
The utility model purpose is to provide a kind of high density infrared ray elevator light curtain for the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
A kind of high density infrared ray of the utility model elevator light curtain comprises power module, controller, projector and receptor, and the mouth of described projector also arranges grating.
The a plurality of infrared light pipes of projector consist of, and tube pitch is 20-50mm.
The utility model greatly reduces the triggering blind area, protects to a greater extent passenger safety.
Description of drawings
Fig. 1: the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of high density infrared ray of the utility model elevator light curtain comprises power module, controller, projector and receptor, and the mouth of described projector also arranges grating.
The a plurality of infrared light pipes of projector consist of, and tube pitch is 20-50mm.
Adopt data transmission technology, every a branch of infrared ray of transmitting terminal emission all is loaded with different " data message ", the wrong report that causes so solve successfully that central combination in enormous quantities is installed the phase mutual interference, fails to report.TMC infrared palisade infrared beam is from 2 light beams-10 light beam, and the interval 20cm between every light beam can be client's other light beams customized (11-40), the infrared palisade of other spacings (5-40cm).
Owing to adopt " data transmission technology " technology, add advanced optical texture, receiving end is only identified the infrared ray that the transmitting terminal vertical launch is come, and has successfully solved because receiving end is received and has reflected failing to report that the infrared ray of coming causes.
What adopt is special-purpose infrared transmitting tube, so successfully solve because the wrong report that the infrared ray that low temperature, sunshine, rain, mist, frost, snow etc. cause is decayed and caused.Because the infrared beam that has adopted data transmission technology, TMC to launch is different from the infrared ray of the various complexity of realm of nature generation, so successfully solve the contained ultrared interference such as sunshine, high light.
Designing a light pipe spacing and be 40mm, 48 pairs of infrared light pipe logarithms, protection highly is that 20～1900mm, guard space are the light curtain of 0～3000mm, adopts the dynamic cross scan of data transmission technology, makes light beam reach 234 and restraints.Greatly reduce and trigger the blind area, protect to a greater extent passenger safety.
The above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
