Description
Technical field
The present invention relates to a kind of improved technologies of microwave radiometer.
Background technique
Microwave radiometer is the meteorologic instrument of continuous measurement atmospheric temperature, moisture profile.Existing microwave radiometer uses band
There is the plastic foam cover of hydrophobic coating, prevents rainwater from entering microwave radiometer antenna and receive feed.But hydrophobic coating is quickly
Will due to dust and sunlight irradiation and be denaturalized become it is hydrophilic, rainwater, which is fallen in again on plastic foam cover, just will form moisture film, thus
Based Microwave Radiometer Detection is influenced, or even microwave radiometer is made to fail.
Summary of the invention
The object of the present invention is to provide a kind of microwave radiometer air curtain rain-proof method and device, with solve microwave radiometer because
Rainfall and the technical issues of change detection performance, and achieve the purpose that fail for a long time.
In order to achieve the above-mentioned object of the invention, the technical solution adopted in the present invention is as follows:
Microwave radiometer air curtain rain-proof method, firstly, the letter that judges whether position is rainy using rain sensor, and will rain
Number as one make gas nozzle generate air-flow blower working control signal；Secondly, being one after the signal with above-mentioned rain
The blower that nozzle provides air-flow is started to work, which generates the gas curtain layer of horizontal breadth, which meets enters in raindrop
After gas curtain, under the action of air-flow, the rainwater to blow off on microwave radiometer host, so that microwave radiometer antenna overhead is not
It will appear moisture film；A wind direction acquisition device, injection direction of the wind direction information acquired as above-mentioned gas nozzle is arranged in third
Foundation；4th, it is arranged to microwave radiometer and the gas nozzle being installed on it to be driven rotatable mode, is believed by wind direction
Air cock rotary breath control microwave radiometer and be installed on it, keeps the injection direction of gas nozzle consistent with wind direction.
Microwave radiometer air curtain rain insensitive device loads onto the air duct with blower in microwave radiometer host side, and air duct goes out
Mouth is on microwave radiometer host top, and the wind of ducting outlet blowout is the gas curtain shape of horizontal direction, i.e., in microwave radiometer overhead
Air curtain is formed, after raindrop enter air curtain, under the action of air-flow, the rainwater to blow off on microwave radiometer host, so that
Microwave radiometer antenna overhead is not in moisture film.
Microwave radiometer air curtain rain insensitive device, the microwave radiometer host are mounted on a rotating platform, there is one
Wind transducer provides signals to rotating platform drive control unit connected to it, which senses according to wind direction
The information control rotating platform rotation of device, so that air duct becomes the wall to keep out the wind, that is, moves the wind of air outlet and natural wind
Direction is consistent.
Microwave radiometer air curtain rain insensitive device, the work of the blower are by the blower working controller connecting with blower
Control, the signal input part of blower working controller connect a rain sensor.
Advantages of the present invention: air curtain is formed in microwave radiometer overhead using the wind of ducting outlet blowout, when raindrop enter
After air curtain, under the action of air-flow, blow off microwave radiometer host, so that microwave radiometer antenna overhead is not in water
Film, microwave radiometer will not change detection performance because of rainfall.Wind transducer measurement natural wind wind direction is devised, and passes through control
Device control rotating platform rotation processed, so that air duct becomes the wall to keep out the wind, to enhance the effect of rain-proof.When not raining, blower
It is idle.Once raining, the rain sensor in meteorological sensor will issue information, will after controller receives information
Blower work is controlled, air curtain is formed in microwave radiometer overhead, prevents rain from falling on microwave radiometer.

Specific embodiment
Microwave radiometer air curtain rain-proof method, firstly, judging whether position is rainy using rain sensor, and will rain
Signal as one make gas nozzle generate air-flow blower working control signal；Secondly, being after the signal with above-mentioned rain
The blower that one nozzle provides air-flow is started to work, which generates the gas curtain layer of horizontal breadth, which meets in raindrop
Into after gas curtain, under the action of air-flow, the rainwater to blow off on microwave radiometer host, so that in microwave radiometer antenna
Sky is not in moisture film；A wind direction acquisition device, injection of the wind direction information acquired as above-mentioned gas nozzle is arranged in third
The foundation in direction；4th, it is arranged to microwave radiometer and the gas nozzle being installed on it to be driven rotatable mode, passes through wind
The air cock rotary for controlling microwave radiometer to information and being installed on it, keeps the injection direction of gas nozzle consistent with wind direction.
Structure and working principle ginseng of the invention as shown in FIGS. 1 and 2.The present invention is blown off raindrop microwave radiation using air curtain
Host is counted, so that microwave radiometer antenna overhead is not in moisture film, microwave radiometer will not change detection because of rainfall
Performance.Integrated blower, air duct are loaded onto microwave radiometer host side, ducting outlet is in microwave radiometer host top, wind
The wind of road outlet blowout forms air curtain in microwave radiometer overhead and under the action of air-flow, blows off micro- after raindrop enter air curtain
Wave radiation meter host, so that microwave radiometer antenna overhead is not in moisture film, microwave radiometer will not change because of rainfall
Become detection performance.
It is shown in Figure 3, it is contemplated that the influence of natural wind devises wind transducer measurement natural wind wind direction, and passes through
Controller controls rotating platform rotation, so that air duct becomes the wall to keep out the wind, that is, makes wind and the natural wind movement side of air outlet
To consistent, to enhance the effect of rain-proof.When not raining, blower is idle.Once it rains, the rain in meteorological sensor
Sensor will issue information, after controller receives information, will control blower work, form wind in microwave radiometer overhead
Curtain prevents rain from falling on microwave radiometer.
The specific works control flow of controller of the invention is shown in Figure 4.
