Cadc Universal Test System Development

The Central Atmosphere Data Computer (CADC) is a necessary measuring equipment to provide data which are displayed by instruments on airplane, engine, automatic control system, piloting system, firepower control system, airline control system and warning system, etc. A universal measuring system (DSQ) for CADC, which is divided into six modules according to the requirements, is developed by the author of this paper. The method to realize the function of each module and comniunications mechanism between modules are introduced by detail in the paper. It also detailedly expatiates functions and methods used in modules and the communication mechanism between modules. Some new technologies and kernel objects are adopted in Windows in order to control CADC to work effectively, steadily and automatically to make the system be manipulated easily. What's more, this system can be easily extended and satisfied requirements of different measuring items. These days, this system has put into practice in an enterprise of war industry, are running well.
