The Remote Real-Time Earthquake Monitoring System of Isolated Structure Based in NI cRIO

Abstract:

The system monitors seismic responses of isolated structure and non-isolated structure in WenChuan with earthquake, and compared with them. The system of seismic sensors collected seismic signals to the FPGA chip, and FPGA transmits the signal to the real-time controller through the internal bus after filtering. The real-time controller monitors signals and triggers the storage, at the same time the controller will transmit data to the host computer through the Ethernet, and the PC as the local server, which can be accessed real-time by remote computers. A plurality of acquisition station support multiple acquisition station synchronization acquisition using the GPS trigger synchronization.
