Research On Software System Of Urban Bridge Safety Monitoring Network

Transport the people’s livelihood and economic lifeline, while the bridge is the key to ensure traffic flow vectors. In order to guarantee the safety of bridge structure,practicality and durability, structural health monitoring technologies. In practice, however, especially in the present, accelerating the process of urbanization, urban expressways intersect, forming a traffic network to ensure smooth flow of traffic in the region. In this way, bridge traffic accident problems may result in the entire region.In response to this situation, proposed the establishment of a cluster of network safety monitor network system of urban bridge, from the perspective of overall management of several bridges in the region, and in increasing the number of monitoring do not redesign of the software, or make simple adjustments can achieve. Can be online at the same time understand the real-time operation of several bridges in the region when a bridge if a problem occurs, you can view the impact on other bridges in a timely manner, so as to take precautions in advance to prevent the occurrence of safety accidents. Around this core, we mainly do the following work:1. Briefly introduces the development of bridge health monitoring system, including its history and composition, after consulting a large number of relevant information, summarized in the construction of urban bridge safety monitor network system of several key issues, including optimization of sensor arrangement, security assessments, data processing and software architecture, as well as data transmission and storage security, and other issues. And focusing on the optimization of sensor arrangement, including its principles of optimization and optimization, as well as the contrast between the various methods, introduced the method of safety assessment and the latest research results.2. Focuses on safe operation of urban Bridge monitoring network software system design of subsystems in detail, include sensor design, the bridge is structurally safe and early-warning system design, database design, and log on to the system design. And modal parameter identification and damage detection of bridge structure and finite element model updating method in detail; determining software, processes, and related functionality is proposed.3. Programming using MATLAB data calculation software for its core programs, namely software for safety monitoring network system of urban bridge. The program can achieve data acquisition, analysis, modal, finite element model updating and warning alarm function; the page friendly, simple operation, easy to manage and analyze, can provide effective management tools for Bridge Management Department.
