Airborne self-adjusting seal cabin provided by the present invention is mainly used in airborne platform, for Infrared
Working environment is detected and controls.As shown in Figure 1, Figure 2 and Figure 3, the airborne self-adjusting seal cabin, including：Sealing cabin 1,
Air purifier 2, air pressure regulator 3, control panel 4, baroceptor 5, humidity sensor 6, temperature sensor 7, heating film group
8；Wherein,
Sealing cabin 1 is for carrying Infrared, including hold 9, middle deck 10 and overhead bin 11；Wherein, hold 9,
It is interconnected between middle deck 10 and overhead bin 11, and the size of nacelle tapers off shape successively；Hold 9 is in eight angle type, surrounding setting
It is useful for the window 12 of Infrared infrared reconnaissance imaging.
The outside of middle deck 10 is provided with the mounting flange 13 for being docked with airborne platform, is arranged on mounting flange 13 useful
In electric connector 14, in airborne platform and cabin control panel, between Infrared into the transmission of horizontal electrical signal.Middle deck
The heating film group 8 that 10 inside is additionally provided with the temperature sensor 7 for detecting temperature in cabin and is heated to gas in cabin.
The top of overhead bin 11 is provided with the air pressure regulator 3 for air pressure in adjusting cabin；The inside of air pressure regulator 3 is arranged
It is useful for dry gas and filters deimpurity air purifier 2；The middle part of overhead bin 11 is provided with control panel 4,5 and of baroceptor
Humidity sensor 6；Control panel 4 is connected with humidity sensor 6, baroceptor 5, temperature sensor 7 and heating film group 8 respectively
It connects, the temperature value control heating film group 8 for being detected according to temperature sensor 7 heats the gas inside nacelle, is used for
Whether the humidity value prompt detected according to humidity sensor 6 is replaced the drier in air purifier 2, and being used for will
Atmospheric pressure value is uploaded to host computer by cable and shows in the cabin that temperature value, humidity value and baroceptor 5 detect.
As shown in figure 4, control panel 4 includes interface chip, power supply chip, processor, relay；Wherein, interface chip with
Processor is connected, for temperature value, humidity value and atmospheric pressure value to be uploaded to host computer by electric connector；Power supply chip is used
In connection external power supply, respectively processor and relay provides required power supply；Relay is separately connected processor and adds
Hotting mask group is heated for controlling heating film group according to the control signal of processor；Processor respectively with baroceptor 5,
Humidity sensor 6, temperature sensor 7 are connected.
Specifically, air pressure regulator 3 uses in Bidirectional gas pressure regulating valve adjust automatically cabin with air pressure out of my cabin, realizes interior external pressure
Poor dynamic equilibrium.Specifically, referring to Fig. 5, in carrier during climbing, as carrier height constantly increases, pressure out of my cabin
It is gradual to reduce.And cabin internal pressure power remains unchanged, and pressure difference gradually increases in cabin out of my cabin, when inside and outside differential pressure is more than preset value, gas
The valve of pressure regulating valve 3 automatically opens, and gas discharge in cabin is made out of my cabin, to make pressure reduction in cabin, is set until reaching balance pressure difference
Until definite value.On the contrary, during carrier declines, as carrier height constantly reduces, cabin inside and outside differential pressure gradually increases, when
When pressure difference is more than predetermined threshold value in outer, then the valve of air pressure regulator 3 automatically opens, and gas enters from the external world in nacelle, makes cabin
Interior pressure increases, until reaching balance pressure difference setting value.
Further, it is provided with humidity indicator on air pressure regulator 3, is integrated in 3 valve exterior surface of air pressure regulator；When
When humidity is higher than 20%RH in cabin, drier is replaced in humidity indicator prompt.Different from humidity sensor, humidity indicator can be with
In the case where sealed compartment powers off, the humidity value in cabin is prompted.When replacing drier, air purifier 2 only need to be opened manually
Upper cover, that is, replaceable drier is not required to disassemblerassembler, safeguards simple and convenient.
And for baroceptor in cabin 5 for monitoring pressure data in cabin in real time, and have the control of control panel 4 by monitoring
Data are uploaded in host computer by cable and are shown.
It is provided with drier and cleanser in air purifier 2, for being dried and filtering to gas.In sealed compartment work
When making (when carrier declines), gas enters clarifier by air pressure regulator 3 out of my cabin, absorbs moisture therein and it is dried
And partial impurities therein are filtered out, ensure that the air dew point temperature in sealed compartment is not more than -60 DEG C.
Wherein, temperature, which is adjusted, uses local warming's regulative mode, and local modulation mode is directed to a certain specific region
Property adjust, be designed according to different parts environmental suitability difference, efficiency of heating surface higher, save power consumption.Specifically, as schemed
Shown in 6, control panel 4 by being powered on to heating film group 8, realize by heating film fever, the mode that heat transfer is carried out to target location.When
When 7 detection zone environment temperature of temperature sensor is less than setting value, control panel 4 controls heating film group 8 and starts to start heating, passes through
Conduction makes ambient temperature rise；When detecting temperature rise to setting value, control panel 4 controls heating film group 8 and stops heating.
Therefore, the present invention can be such that regional environment temperature is maintained in range of set value, ensure that the regional function component works normally.
Volume weight increase in airborne self-adjusting seal cabin provided by the present invention is less, and people is not necessarily in larger altitude range
Work intervention can meet system requirements.The configuration of the present invention is simple, dependable performance, easy to maintain, at low cost, easily realization.In addition, through
High Altitude Platform experiment is crossed, airborne self-adjusting seal cabin meets airborne circumstance requirement, passes through baroceptor 5,6 and of humidity sensor
7 return data of temperature sensor reaches good design effect, and typical data is as shown in table 1 in actual measurement aerospace seal cabin, ensures
Infrared normal work.
