IoT technology for the bridge "examination" bridge "sick" will automatically alarm

WASHINGTON Yesterday from the Wuxi Municipal Facilities Management Office was informed that Wuxi has built a city bridge information management platform, using IOT technology to bridge real-time "physical examination" and real-time updates of each bridge basic information, disease conditions and conservation. At present, the platform has passed the appraisal of achievements of science and technology demonstration projects of the Ministry of Housing and Urban-Rural Development and is being promoted to the inside and outside of the province.

According to reports, many bridges in Wuxi span span, bridge type, complex structure, manual testing is both time-consuming and more difficult to complete, accuracy is not enough. In order to make the bridge more subtle and intelligent, as early as 2009 municipal facilities management office developed the "urban bridge information management system" for each bridge prepared a separate "ID card" and "health file." Staff on the computer can remotely view the bridge's birth date, size, structure, type and other basic information, and in accordance with the "bridge a file" to implement "household type" management. Last year, the "Urban Bridge Information Management System" was upgraded to "Urban Bridge Information Management Platform in Wuxi City", a collection of three systems of bridge management information system, structural health real-time monitoring and video monitoring.

According to municipal facilities management office technical staff, the upgraded management platform uses information technology, combined with the Internet of Things technology, big data mining and other functions. On the one hand, the platform can monitor the condition of the bridge in real time, including the locking force, deflection, strain, vibration temperature, pressure and wind speed of the bridge. Once the data exceeds the set warning line, the system will automatically alarm, and send SMS to the custody department responsible for the timely response to deal with. At present, the real-time monitoring of structural health of bridges has been applied to the Ronghu Bridge and the Open Source Bridge. There are 83,114 sensors installed around the bridges of these two bridges. Among them, a variety of acceleration sensors are deployed on the bridge, The natural frequency of the cable is measured by measuring the acceleration of the stay cable to infer the health of the cable. In addition, the upgraded platform also adds regulatory tracking capabilities. The management department is equipped with input devices for the bridge inspection personnel. Each inspection shall record the inspection and maintenance information and the custody matters, and the inspection personnel can only enter the information within 50 meters of the site to successfully enter the information. "The big advantage of this function is that it avoids the maintenance workers' making cars behind closed doors and improving the effectiveness and safety of bridge testing."

At present, the city bridge information management platform has been the city's 320 bridges into the management, the future will gradually bring all the city's bridges into the city platform to achieve integrated management. Meanwhile, the real-time monitoring of the health of the bridge structure will be promoted in the eight special structural bridges in Xicheng, and the next step will be applied to the Yonghu Bridge.
