深圳湾大桥结构健康及安全监控预警系统硬件概述

Hardware Introduction of Structure Healthy and Safety Monitoring Systems for Shenzhen Bay Bridge of Shenzhen-Hongkong Western Corridor

通过对已完成实施的深港西部通道深圳湾公路大桥结构健康及安全监控预警系统(SZBHMS)的介绍,综合阐述了研发系统的构建与硬件内容。在系统中选用了基于美国NI公司虚拟仪器技术的数据采集设备硬件和基础软件产品,并采用了GPS技术时钟授时接收机等技术。结果表明:系统能够协调运行,实现了预期设计功能,保证了SZWBHMS系统长期运行的高可靠性、实时性以及技术的先进性。

Though the brief introduction of the completed Sheng Zhen Wan Bridge Healthy Monitoring System （SZWBHMS） for Shenzhen Bay Highway Bridge of Shenzhen-Hongkong Western Corridor, the self-developed system frame and hardware scheme of this practical research project are systematically discussed in this paper. The data acquisition and transmission hardware and the basic software produce based on the NI （National Instruments） Company virtual instruments technology are selected in this system, which adopted GPS time service receiver technology and so on. The results indicate that the performance of the system achieves the desired objectives and ensures the long-term high reliability, real time concurrence and advanced technology of SZWBHMS.
