Smart City is a high-level form of urban informatization based on the next generation of innovation in the knowledge society (Innovation 2.0) that fully utilizes the new generation of information technology in all walks of life in the city. Smart City is based on the next generation of information technology such as Internet of Things and cloud computing, as well as the application of tools and methods such as wiki, social network, Fab Lab, Living Lab, and integrated integration method to create an ecosystem that is conducive to innovation and achieve comprehensive and comprehensive perception and broadband. Ubiquitous interconnection, intelligent convergence applications, and sustainable innovation characterized by user innovation, open innovation, mass innovation, and collaborative innovation.
Smart city architectureThe architecture of a smart city can be divided into three layers: the information acquisition layer, the operational control layer, and the leadership decision support layer.
1. Information collection layerUse video surveillance, RFID technology, various sensing technologies, real-time measurement, acquisition, event collection, data capture and identification of various data and events in the city.
2. Operational control layerAfter processing the collected data and event information, according to the workflow modeling and scheduling, event information processing, automatically selecting countermeasures, notifying the relevant responsible person, performing workflow processing, historical information retention and query, network equipment monitoring, and the like.
3. Leadership decision support layerCity managers can conduct multi-sector simulation exercises, information query and monitoring, workflow process visual monitoring, historical data analysis, related expert collaborative analysis, urban management process optimization; intelligent management of cities and handling of various emergencies Provide data support and empirical analysis.
The smart city includes a lot of content. From the construction content, it can be divided into infrastructure construction (mainly basic network construction), application of information technology, and intelligent construction of various industries. From the perspective of different objects, it can be divided into smart government affairs. , wisdom industry, wisdom and people's livelihood three major content. The layer-by-layer construction is carried out according to the unified top-level architecture design principle, and the final evaluation is carried out according to the unified construction standards and evaluation system.
At present, there are many companies engaged in the construction of smart cities. First, they are the three major communication operators. At the same time, they include large state-owned enterprises and research institutions as export units of technological innovation, providing R&D and exploration of various cutting-edge technologies, standard formulation and guidance, etc. .
With the emergence of distributed caching and computing, the ensuing problem is how to establish and develop a third-party platform. If smart city technology providers want to work with government agencies, they must consider the security of resources, data, APIs, etc., because only then can new intelligence, new applications and new experiences be created. Of course, the so-called third-party platform development is not simply to create a "smart city APP", we need to focus all of our attention on an advanced review mechanism to clearly understand and determine which applications can be in the real environment. Open and application.
2. Distributed computingIn smart cities, the speed of our data processing is also accelerating due to the rapid development of the network. This not only makes it impossible for city managers to re-send all content to the “cloud†for centralized processing, but also increases data processing. Difficulty. Therefore, we must build high-value nodes with local processing resources to run seamlessly as hierarchical participants in a distributed network. In addition, the municipal infrastructure must be integrated into a comprehensive distributed processing architecture, a scalable living system that connects rich data.
3. High speed, low latency networkHigh-speed, low-latency wireless communication networks are the primary requirement for smart city construction, which is why the emergence of 5G networks will receive so much attention.
4. Advanced "disaster prevention" energyIn smart city solutions, the most important is a sustainable, secure and disaster-resistant energy network. Without this subsystem, smart cities are not enough to be called smart cities. So no IT engineer can set up a data center without a UPS (uninterruptible power supply) and backup power.
5. Security privacySmart cities should integrate “security†from the outset to smart city platforms because unsafe solutions are not acceptable. Moreover, with the intrusion of video surveillance systems and home care cameras in recent years, smart city systems should propose more secure and efficient products and solutions when integrating resources. Access protocols and communications require advanced security architecture to prevent maliciousness. proxy.
