Abstract：

A　vibration　signal　acquisition　system　was　designed　based　virtual　instrument　technology.　The　process　and　principle　design　of　structure　vibration　signal　acquisition　system　based　on　LabVIEW　software　and　CompactRIO　hardware　were　discussed　in　detail.　Finally,　system　test　was　conducted　by　a　three　story　steel　frame　structure.　And　the　test　results　were　compared　with　traditional　instruments　system.　The　experiment　showed　that　the　data　acquisition　system　of　structure　vibration　signal　which　based　on　CompactRIO　is　precise　and　reliable　in　measurement　results,　and　can　realize　multi　channel　synchronous　data　acquisition,　storage,　and　support　the　real-time　online　data　filtering　and　spectrum　analysis　and　so　on.Compared　with　the　traditional　platforms,　the　system　proposed　in　the　paper　has　short　development　cycle,　low　cost,　user-defined　functions,　rugged,　portable　and　other　advantages.　It　can　be　widely　used　in　complex　and　special　building　environment,　so　it　will　have　a　broad　application　prospect　in　the　field　of　SHM.　©　(2014)　Trans　Tech　Publications,　Switzerland.
