Bridge structure safety monitoring

China Railway Design Group Co., Ltd. (referred to as China Railway Design Group), formerly known as China Railway Third Survey and Design Institute Group Co., Ltd. (China Railway Third Survey and Design Institute), is the only design enterprise under China National Railway Group Co., Ltd. Established in 1953 and headquartered in Tianjin, it is a large enterprise group mainly engaged in railway, urban rail transit, highway and other engineering survey, design, consulting, supervision, engineering general contracting, and product industrialization business, Having a Class A certificate of comprehensive engineering design qualification, it is one of the first batch of high-tech enterprises recognized by the country. The comprehensive strength of the enterprise ranks at the forefront of the industry. In 2022, ENR ranked 37th among the top 150 global engineering design companies, 103rd among the top 225 international engineering design companies, 35th among the top 80 Chinese contractors, and 5th among the top 60 Chinese engineering design enterprises.

　The bridge structure safety monitoring collects the deformation, stress, environment and other key parameters of the key structural points of the bridge, and transmits them to the platform through the edge computer 5G/4G industrial wireless gateway BMG700 to achieve real-time monitoring, statistical analysis, abnormal alarm, remote management, etc. of the bridge structure safety. It can achieve 24-hour real-time monitoring: fully automated online monitoring of bridge deformation, stress, environment, etc., and real-time grasp of the overall operating status of the bridge. Report automatic push: Monitoring results are published in real-time, and monitoring reports are regularly pushed to users. Multiple level warning: When data is abnormal, the system will trigger the corresponding three-level alarm mechanism, and notify users in the form of text messages, faxes, broadcasts, and other forms as soon as possible. Emergency response plan handling: Directly extract corresponding handling methods from the expert database, and promptly take measures such as personnel intervention and road blockade to eliminate safety hazards in the bud. Structural trend analysis: Through quantitative safety evaluation and monitoring index data safety analysis of bridge structures, structural stability trend analysis can be achieved. Provide reference basis: long-term stable storage of monitoring data, providing analogical basis for similar engineering design and construction in the future.
