Though the brief introduction of the completed structural health and safety monitoring warning systems for
Shenzhen-Hongkong western corridor Shenzhen bay highway bridge (SZBHMS), the self-developed system frame, hardware and
software scheme of this practical research project are systematically discussed in this paper. The data acquisition and
transmission hardware and the basic software based on the NI (National Instruments) Company virtual instruments
technology were selected in this system, which adopted GPS time service receiver technology and so on. The objectives
are to establish the structural safety monitoring and status evaluation system to monitor the structural responses and
working conditions in real time and to analyze the structural working statue using information obtained from the
measured data. It will be also provided the scientific
decision-making bases for the bridge management and maintenance.
Potential technical approaches to the structural safety warning systems, status identification and evaluation method are
presented. The result indicated that the performance of the system has achieved the desired objectives, ensure the longterm
high reliability, real time concurrence and advanced technology of SZBHMS. The innovate achievement which is
the first time to implement in domestic, provide the reference for long-span bridge structural health and safety
monitoring warning systems design.
