Abstract :
This paper developed a set of 64-channel information acquisition system, which included signal acquisition unit, signal modification unit, signal communication, PCM encode unit and optical fiber communication unit. The optical fiber communication unit solved the problems such as electromagnetic interference and signal dropframe. The system was demonstrated for its simplicity and stability during initial experiment.
