Shanghai: Smart City vision with the Internet of things embedded in transportation infrastructure
A white-collar working within the inner ring of Shanghai will receive APP push notifications ahead of the week, informing if there is construction plan of the route to his workplace. When overloading vehicles are going onto the bridge, an automatic alarm will be triggered by sensing the stress change of the bridge and the custody unit will be notified at once. With the test run of the intelligent traffic infrastructure operation and maintenance management platform in Shanghai, the vision of the smart city is coming into reality.
According to DuanChuangfeng, Dean of the Tunnel Co. Underground Design Research Institute of Engineering Technology, the platform supports the whole life cycle management and decision-making of the traffic infrastructure, including rapid detection, GIS and BIM technology, networking, cloud technology and big data mining in one. It can be applied to roads, bridges, tunnels and other city traffic. As long as the sensor in the traffic facilities is connected to the platform, you can monitor the load and operation of each facility in real time.
Taking the Songjiangchen Tower Bridge as an example, 181 different kinds of sensing devices were implanted in the bridge. The GPS measuring station at the top of the tower can monitor and issue an early warning of the structural deformation of the bridge. The dynamic load bearing instrument under the pavement can monitor the vehicle load and accurately determine the overload vehicles. Microscopic monitoring data will be sent to the platform in real time, and the operation and maintenance department of the single project can receive the information through the platform interface which provides big data basis for their decision-making or strategy.
