Smart City 4-story model structure and 13 key technologies
The common model of smart city is divided into bottom-up: perception layer, communication layer, data layer and application layer; and perfect standard system and security system. Smart city model as shown below: The perception layer is the basic condition for a smart city to realize its "wisdom." Perception layer has superior environmental perception and intelligence, through the RFID, sensors, sensor networks and other Internet of Things technology to achieve city-wide infrastructure, environment, construction, security and other monitoring and control, for individuals and the community to provide no Not everywhere, omnipotent information services and applications. The communication layer is an information superhighway in smart cities and an important infrastructure for smart cities in the future. The future city's communications network should be composed of high-capacity, high-bandwidth, high-reliability optical network and citywide coverage of the wireless broadband network, in order to achieve the city's intelligence laid a good foundation. At the same time, let the public "anytime, anywhere, with on-demand" can broadband Internet access, but also enjoy the network television, high definition television, high definition video calls and other broadband services. The core purpose of the data layer is to make the city more "smart". In the smart city in the future, data is a very important strategic resource. Therefore, building the data layer of a smart city is a very important part of the smart city construction. The main purpose of the data layer is to solve the problem of data fragmentation and inability to share by technologies such as data association, data mining and data activation. The data layer includes data centers of various industries, departments and enterprises as well as municipal-level dynamic data centers and data warehouses for data sharing and data activation. Application layer mainly refers to the perception layer, communication layer, data layer based on the establishment of a variety of applications. Smart industries, smart management and wisdom and livelihood of the wisdom of the application layer, to promote the realization of "industrial development, functional improvement, livelihood and happiness," the wisdom of the city. Citizens can access these systems through various terminals, and citizens can personally experience the happiness and harmony of urban life. 1.1.1.1 Technical System Smart cities are undoubtedly supported by modern information technology systems. Smart City Building contains at least 13 key technologies that can be categorized into devices and device related technologies, network communications technologies, application services, and scenario computing technologies that are important to the user experience. 1. Equipment and device related technology (1) Ubiquitous Sensor Network: Provides a ubiquitous communication environment for small, embedded devices with sensing capabilities. (2) RFID: An RFID tag and RFID reader to automatically identify the identity of the object technology. Can support from 1.8 meters to 27 meters distance. (3) System on Chip SoC: Integrate as many computer components as possible on a single chip. (4) GPS: Global Positioning System, location service. 2. Network Communication Technology (1) Broadband Aggregation Network BcN: Integrated next-generation wireless wired network that aggregates voice, data, Internet, communications and broadcast services. Expected endpoint Internet access speed 50Mbps to 100Mbps. (2) FTTx: optical fiber communication directly to the user premises. (3) HSDPA and Wireless Broadband Network WiBro: wireless Internet technology, users of mobile multimedia content experience on the PC to achieve the same effect. (4) IPv6: Internet network layer protocol, IPv6 successor. IPv6 addresses the issue of the limited number of IP addresses for quite a long time. 3. Application service technology (1) Simulation Technology in Middleware: Computer software that connects software components or applications and supports complex distributed applications. (2) Telematics Telematics: The use of communications equipment, to achieve the transmission, reception and storage of information services. Mobile computing for integrated GPS systems. (3) GIS: geographic information system. (4) Cloud Computing: Cloud computing is essentially a new service model that leases resources on demand and is a new type of Internet Data Center (IDC) service. 4 scenarios computing technology (1) context-aware computing: The device can obtain and identify the information of the surrounding environment and decide to provide different services to the crowd at a specific time, place, time. At the concert scene, the phone is automatically set to vibrate mode (at least through a preset concert schedule. (2) Augmented Reality AR: The combination of real-world and computer-generated data is the most exciting technology in smart cities. Smart city construction technology system diagram as shown below:
