| dc.description.abstract | In early stage, the investigators have to go to the location of data acquisition unit and fetch the data in person. Owning to dramatic innovation in communication technique, modems play an important role to communicate bilaterally between personal computer and data acquisition unit. Furthermore, the broadband network access, ISDN, ADSL, Cable Model etc., offers the possibility of real-time and on-line monitoring and adjustment. By the faster and more reliable data collecting technique, a prototype on-line monitoring system would be established. In this paper, monitoring system with broadband network will be introduced in detail, the monitoring and analysis program about earthquake response characteristics of the structure would be developed and meet the request of use monitoring system with broadband network to transmit the data. The program functions include：(1) on-line adjustment of monitoring system,(2) real time data analysis,(3) real time warning system,(4) timer setting of monitoring system,(5) data processing and analyzing. In the process of research, broadband network to transmit data and remote monitoring are applied in forty-day test to verify the practicality of the program and investigate the influence of sampling rate on real time performance of monitoring system. It is found that the whole system does show its potential to be installed in a real structure as a health monitoring system. Therefore, the broad-band network monitoring system processes the possibility in practical applications. | en_US |
