| This subject is a project it mainly finished manually and automatically testto which the main performance index and performance of the controller ofintegrative measuring. It introduced the current situation with domestic andinternational and development trend of automatic test system at first as wellas general situation of the development of locale bus test system in the domestic.According to measured the target's demand, module conceptual design wasproposed by the test system, its main function modules include: output signalsource module (including the module in which the signal examined by itself),long-line transmission module, memorizer testing module, PCM regulate module,Interface control circuit module. There is recite mainly for output signal sourcemodule and long-line transmission module. The article introduced the composingtheory of the examining system, discussed the key technology and difficultproblems in every functional module of the testing system, and combining therelevant documents and debugging situations of system, it gave a general expoundto the dependability of the system;In addition, combining anti-jamming questionit also offered various kinds of anti-jamming measurements to the system,including the power design, PCB board arrangement and the anti-jamming designof hardware and software of the one-chip computer system etc..Then the system has been used and participated in many tests. Through thesetests, we can conclusion the system is accord with the performance target ofthe task. |
