Modern city governance needs a powerful “city brain”. Shanghai Electric’s urban governance solution divides the overall architecture of the city into five layers: perception layer, communication and network layer, urban data and control layer, urban application layer, and support system layer. The solution covers every operating sector in the city, and aims to achieve the cross-departmental, cross-regional, cross-level, and cross-industry collaborative management and data sharing by integrating urban business, information technologies, and mass data. The whole system can collect and analyze data from all areas, ensuring the interconnectivity of urban information. Research and analysis are conducted based on data to find inherent laws and operation tendencies as the powerful support for the city managers’ decisions. Build a “1+3+N” data application system: one 3D demonstration platform, three public application areas, and N application scenarios in city governance:1： One 3D demonstration platform Demonstrate all kinds of urban targets and data with 3D geographic information technology to help government authorities make well-informed decisions, implement precise governance and provide efficient public services.3： Three public application areas Develop three sections: public security, public management and public services Enable IntelliSense by providing early warning and monitoring based on business cases and workflows and further enhancing it with data mined using front-end sensors.N： N application scenarios in city governance Develop tailored application scenarios for specific problems in city governance. Realize the interconnectivity of things, data and smart applications within the area by connecting data collected from front-end sensors and systems.
