Monitor the air absolute pressure in two cabins；Oxygen sensor 1, carbon dioxide sensor 2, temperature in high-precision environment sensor
Humidity sensor 3 monitors life indoor environment parameter respectively；Because transfer chamber 18 and accommodation 17 are separated by transfer chamber door sealing,
Therefore be provided with button box 10 in transfer chamber, to enter and leave cabin operation, on button box 10 equipped with into cabin button and into cabin indicator light,
Cabin button and out cabin indicator light out；Because of cabin seal request, the line set of crossing of crossing cabin cable has all done encapsulation process；In addition it considers
The case where highlands alternating current is unable to supply guarantee happens occasionally, equipped with UPS uninterruptible power supply 14 to control system emergency service.
When people enters compression chamber for the first time, control system power supply is given, hatch door is closed, in transfer chamber 18 or accommodation 17,
Start control system Self-pressurizing agri until pressure set points, and pressure in cabin is maintained to stablize；When of short duration cabin out, personnel were introduced into
Cross cabin, be then shut off transition hatch door, press on button box 10 go out cabin button, transfer chamber 18 decompression until with ambient pressure environment phase
Deng opening hatch door at this time goes out cabin, and accommodation 17 is simultaneously unaffected and continue to accommodation pressure；When again into cabin, cabin is closed
Door presses the enterprising cabin button of button box 10, and transfer chamber 18 pressurizes until equal with accommodation pressure, at this time openable transition hatch door
Into accommodation 17；It can so add repeatedly, decompression process passes in and out cabin；When some environmental parameter exceeds working range, accommodation
Start ventilation, continues under the premise of pressure is stablized for into fresh air, intermittent decompression, guaranteeing that indoor environment is comfortable to a certain extent
Property；When long-time does not use cabin, control system to two cabin automatic pressure-reducings to stopping working after the value of cabin out, at this moment power off from
Cabin；In addition, can be replaced by washing of tanks knob on button box 10 to cabin air before use, at this moment four plus-minus piezoelectricity magnetic
Valve opens simultaneously progress air inlet and loses heart.This completes air pressurized cabin use processes and transfer chamber 18 frequently to enter and leave process,
