Design of Intelligent Health Monitoring Hybrid Information System for Large Bridge Structures

Abstract

Because the bridge structure health monitoring system involves multi-disciplinary knowledge, the original system has some defects such as chaotic information storage and poor monitoring precision, which seriously hinders the development of bridge structure health monitoring technology. In order to solve the above problems, the design and research of large bridge structure intelligent health monitoring hybrid information system are proposed. The hardware of the system includes the selection unit of prestressing tensioning measuring device, the selection unit of industrial control machine, the selection unit of data exchange machine and the selection unit of sensor. Through the design of the hardware unit and its software module, the intelligent health monitoring hybrid information system of large bridge structure is realized. Compared with the existing system, the experimental data show that the accuracy of bridge structure health monitoring is higher, which fully proves the effectiveness and feasibility of the design system.
