It needs distribute system for vibration signal test and analysis of complicated structure. Broke through the limitation of exiting form, this paper presents a C/S mode vibration tent system based on 3G. It involves a high performance testing client, which is resolution 24 bits and DNR 109dB and responsible for local test and analysis, and remote server for completing broad band algorithm for auto machine confident. The client and server exchange their data in real time via 3G network with myself control and in the form of multimedia stream. Test shows that the solution is viable and it can be a reference system for the requirement of C/S mode.
