Development and Application of the Leakage Examination System for a Spacecraft-airproof-checking Room

The leakage examination systems for a spacecraft-airproof-checking room is developed in order to assure the airproof of a spacecraft is safe and trustiness through the analysis result of the airproof checking.The technology of the modern computer and auto control are used in this system,and some problem about the leakage measure,configure system is solved.The robustness of system,the precise of temperature and pressure are observably improved as charge coupled,increase the amplification constant,decrease measure scope,etc.the method of correction error are adopted in the system.The actual results presented to verify this system can suffice the requirement of leakage examination.
