Description
Technical field
The present invention relates to a kind of visibility pick-up unit.Specifically, be to be used for the atmosphere of greasy weather or dust and sand weather is detected so that remind the safety-conscious atmosphere visibility of human pilot pick-up unit.The visual range that is particularly useful for occasions such as highway, airfield runway and rivers,lakes and seas detects, prompting.
Background technology
As everyone knows, the visibility of greasy weather or dust and sand weather is lower, if in time the visibility of atmosphere is not detected, points out in occasions such as highway, airfield runway and rivers,lakes and seas, car, ship and plane collision very easily occur.
China ZL991141636 patent of invention instructions discloses a kind of sensing and controlling device for fog weather.This sensing and controlling device for fog weather is made up of humidity sensor, optical sensor, humidity amplification controller, light amplification controller and electric executive component switch; Optical sensor wherein is made up of photocell and light receiving element, is provided with refracting glass between photocell and the light receiving element.Electricity executive component switch adopts relay switch, transwitch, transistor switch and digital switch circuit, and its signal input part links to each other with the output terminal of light amplification controller, and electric executive component switch series is connected between the output terminal and input end of humidity sensor.Said humidity amplification controller and light amplification controller all are made up of bulk component, and their output all is connected to relay and signal lamp.During work by the suction of relay, close electric signal that has mist (or sand and dust) still not have mist of output, will have mist (or sand and dust) still not have the signal of mist to show through signal lamp again, note driving safety to remind human pilot.Because electric executive component switch adopts relay switch, transwitch, transistor switch and digital switch circuit; Make sensing and controlling device for fog weather can only show mist (or sand and dust) and still do not have two kinds of signals of mist; Can't differentiate and show such as mist, heavy fog, thick fog grade, can not an atmosphere visual range prompting accurately be provided to human pilot.Again because said humidity amplification controller and light amplification controller all are made up of not only structure more complicated, and poor-performing bulk component.In addition, owing between photocell and light receiving element, be provided with refracting glass, refracting glass can absorb a part of light, therefore can cause the detection error.
Summary of the invention
The problem that the present invention will solve provides a kind of atmosphere visibility pick-up unit.This atmosphere visibility pick-up unit, relatively simple for structure, better performances can avoid detecting error, can realize remote prompting, early warning, can an atmosphere visual range prompting accurately be provided to human pilot.
For addressing the above problem, take following technical scheme:
Atmosphere visibility pick-up unit characteristics of the present invention are to comprise two supports, and a relative side of two stands all has the tubular protective cover, and two tubular protective covers are coaxial and all be lateral arrangement, and their outer end is separately fixed on the two stands.In the tubular protective cover white light emitter and amasthenic lens are arranged, in another tubular protective cover optical receiver and light pipe are arranged, said amasthenic lens and light pipe are positioned opposite, and said optical receiver is a chromaticity transducer.Communication antenna, temperature/humidity sensor and cpu controller are arranged between two stands, the GPRS communication system is arranged in the cpu controller.White light emitter, optical receiver, communication antenna and temperature/humidity sensor all link to each other with cpu controller through cable.
Take such scheme, have the following advantages:
Can find out by such scheme; Because said optical receiver adopts chromaticity transducer; Can directly the light of varying strength be converted to the numeral of different sizes; And be divided into a plurality of grades according to digital difference and show by signal lamp by cpu controller; Demonstration according to signal lamp; Just can tell mist, heavy fog, thick fog grade, thereby an atmosphere visual range prompting accurately is provided to human pilot.
Again because the present invention adopts temperature/humidity sensor and optical receiver, and temperature/humidity sensor and optical receiver all are integrated components, need not a bulk component, make simple in structure, dependable performance.
In addition, owing to be provided with the GPRS communication system in the cpu controller, utilize the GPRS communication system can realize telecommunication, thereby in advance the atmosphere visibility situation in the place ahead is informed human pilot.
On the other hand, because the present invention contains two supports, a relative side of two stands all has the tubular protective cover, and two tubular protective covers are coaxial and all be lateral arrangement, and their outer end is separately fixed on the two stands.In the tubular protective cover white light emitter and amasthenic lens are arranged, in another tubular protective cover optical receiver and light pipe are arranged, said amasthenic lens and light pipe are positioned opposite, and said optical receiver is a chromaticity transducer.Between photocell and light receiving element, do not have refracting glass, thereby avoided to absorb a part of light and the detection error that causes by refracting glass.
Description of drawings
Fig. 1 is an atmosphere visibility pick-up unit synoptic diagram of the present invention.
