The Design And Implementation Of The Ground Test Equipment For U Series Of Airborne Computer

U series airborne computer, as the exchange-center and control-center of theairborne supreme fighter aviation fire control system, is the core of the system. Thesupplementary testing equipment bears the multi-tasks of debugging, testing, repairingand inspecting the U series airborne computer. Overwhelming tasks against inadequatetesting equipment, is seriously affecting the productivity of the host computer units andthe aircraft integrity protection for the users. As for this, a domestically-designeddetecting equipment comes into the need to be developed, which is required to be ableto replace the original equipment while miniaturizing the user-computer interactioninterface and control button (knob) basing upon the IPC, and ultimately realizing theportable testing equipment.In this paper, a new type of testing equipment hardware system is to be designed,by referencing to the analysis of foreign testing equipment software system, andcombining the U series of airborne computer’s working principle, working mode andUUT (Unit under Test) equipment’s testing mechanism. Through function dividing andmodular designing, the interface device software and user-machine interactionequipment software and other software have been achieved in the new testingequipment hardware system.Practical tests and operations indicated that the testing equipment hardware systemcovered every function the foreign equipment displayed, realizing the BUS informationcollecting, controlling and detecting of the U series of airborne computer, meeting allthe performance requirements, and isolating the fault to the SRU (Shop ReplaceableUnit). Meanwhile, the testing equipment hardware system solved the demands fromusers’ operation and maintenance, and enterprises’ development and production need,filling the blank of the domestically-designed U series airborne computer testingequipment.
