The Design of General Automatic Testing Platform for Automatic Flight Control Computer

Abstract

The built-in test of the aircraft can identify the fault on the automatic flight control computer when the automatic flight control computer is in failure. The ground crew deliver the automatic flight control computer to supplier for testing and maintenance, which is wasting time and ineffective, so the general automatic testing platform is designed. The interface and function modules, which need to be simulated are identified by the general automatic testing platform through researching the interface relationship of the automatic flight control computer. The hardware platform of the general automatic testing technology based on general standard instrument bus architecture, and the software platform based on standard automatic test makeup language(ATML) description to realize the hardware free extension, software independence, and portability independent of hardware and operating system. According to the interface, function and composition architecture design of automatic flight control computer, the test methods and test flow of each functional module are designed, and compiled into the operational test assemble with ATML. The platform is of good effect on trial, can can realize fast locating of fault module, and shorten the maintenance time.
