Abstract


The switch matrix is the hub of the voice and image transmission system . Usually a switch matrix capacity are smaller, more no audio , the video sync switch . This project due to the lack of audio and video matrix switching system of China's manned space launch site, a center of the image , the paper a detailed study of the problems of the original switch matrix analysis of the intrinsic link between these problems and the key to the proposed the ideas and methods to solve these problems . The subject objectives is to develop a machine that can achieve the audio , video synchronization switching equipment , the paper studies the functional and performance requirements of the use of the environment of the equipment , the design of the internal functions and external features of the device , and these external to the rational structure of the system characteristics. The center of the content of this article is the design of the equipment , analysis equipment , including the original demand function argument , the overall performance requirements , system architecture design , function method , the functional design of the various sub-systems , hardware and software design , electromagnetic compatibility and printed circuit the design of the plate , and the like. The paper described in detail the various parts of the problem to be solved and the corresponding solutions , elaborate design ideas and circuit structure and working principle .
