I often hear people talking about smart cities. Do you know what a smart city is? what is the benefit?
A smart city is an inevitable outcome of the convergence of the achievements of industrialization, informationization, and urbanization in today's society. It is produced with the development of a new round of information technology such as the Internet of Things, a new generation of mobile broadband networks, and cloud computing. It is highly innovative and highly recognized, which will make a major change in people's life production methods and ways of thinking. .
Smart cities can promote energy conservation and emission reduction, promote urban industrial restructuring; establish an effective safety monitoring network to ensure food and drug safety; integrate public service facilities to meet people's needs in medical, education, and health ; can also respond to emergencies quickly and effectively. Smart cities are a solution to the coordination of deep-seated problems in the process of urban development. The most striking feature is the ability to fully understand and coordinate.
How to develop a smart city
Top-level design
First of all, we must understand the existing and upcoming problems in the cities under construction, analyze the causes of the problems, and explore ways to solve the problems. When analyzing problems and researching and solving problems, we must give full play to the wisdom of the builders. A lot of problems have been analyzed and solutions have been proposed, but it is not the main problem. This is "white wisdom." When analyzing the main problem, I found the wrong question, and that is "smart wisdom." The main problem to be solved in the top-level design is to rationally control the scale of the city, rationally allocate resources, minimize the damage to the environment, and sacrifice the least, and give the urban sustainable development. Second, do the design of the data layer. Collect, collect, and integrate urban basic data and information (population, housing, economy, etc.), resource data and information (data, consumption, capacity, facilities, etc.); third, do a good job in the design of existing layers, such as urban planning. Urban construction, urban operation and maintenance, and management will serve the people and benefit the people. This involves various industries such as urban construction, transportation, education, medical care, insurance, security, disaster prevention and mitigation, so that urban resources can be rationally allocated, and urban residents can get better services and better environment.
2. Construction of the perception layer
Mainly the acquisition and storage of basic data
3. Construction of the network layer
The data collection, sample acquisition, and identity identification of the smart city's perception point need to transmit the acquired data to the data center. The transmitted data is massive. To complete this task, a high-speed communication network is required. With the development of smart cities, the application system continues to expand, the amount of information transmission will continue to increase, and rapidly increase. Therefore, the construction of communication networks in the construction of smart cities is very important.
4. Application layer construction
There are three basic construction tasks: the urban basic space geographic information database, the urban public information database, and the urban public information platform.
What is a safe city and intelligent transportation
The most basic and most important components of the construction of “Safe City†and “Intelligent Transportation†are the front-end video surveillance system, the intelligent transmission platform carrying the transmission network and the back-end. The integration of the two is conducive to interconnection and interconnection, saving construction costs and construction period. It is of great significance to improve the city's visual management level and government emergency response capability, and to maintain urban public safety and public order. Next, we will describe the smart city solution through the case of safe city and intelligent transportation integration, and show the intelligent traffic management system. , social resources and the integration of the Gongan Information Network.
1. Safe City
(1) The construction of safe city will realize the digitization and intelligence of Gong'an business through data sharing, analysis, mining and judgment, and improve the ability of Gong'an organs to “play, prevent, control, manage and serve the societyâ€, and achieve command unity and response. Timely, effective goal of zuo warfare, to strengthen the city-level security and prevention capabilities, squeeze crime time and space, and achieve effective management of the city.
(2) Safe City System Architecture Architecture System consists of five levels: monitoring resources, transmission network, sharing platform, monitoring center and management application. Video resource layer: transmission network; sharing platform; monitoring center; management application layer.
(3) Ping An City Platform Software Software Management Platform System is the superstructure of Ping An City and the core of the application layer of Safe City. If the video capture, codec technology is likened to the eyes of a safe city, then the platform software is the brain of a safe city. The Ping An City platform software is divided into operation and maintenance management platform, network sharing platform and intelligent actual combat platform. The intelligent combat platform concentrates on the most important functions of Safe City and requires Zui high.
(4) The intensive monitoring point deployment of Ping'an City's intelligent video analysis system is woven into the city's Zhian prevention and control network, but the huge amount of information will also bring new problems, such as the dozens of roads facing even hundreds of roads. Walls, monitors are often distracted, and the discovery and handling of sudden intrusions and unusual suspicious events increases the difficulty of post-detection. The intelligent video analysis system introduces intelligent behavior analysis perimeter prevention, intelligent face capture comparison function, intelligent video quality diagnosis and other functions.
(5) Ping An City wireless monitoring system based on wireless network monitoring system advantages: high cost, flexibility, convenience, protection of the original infrastructure layout, etc., so wireless monitoring applications are particularly suitable for implementation in rivers, forests, tourism Areas such as scenic spots, as well as management and monitoring of individual soldiers and vehicles. With the reduction of wireless communication and transmission costs, diversified methods, and improved security performance, wireless monitoring systems are becoming an important component of the layout of safe cities.
2, intelligent transportation
The introduction of the intelligent transportation concept has provided new ideas for solving problems such as traffic congestion and driving safety. Intelligent transportation introduces new technologies represented by the Internet of Things and cloud computing, and establishes an integrated transportation system with greater time and space to improve the operational efficiency of urban traffic, reduce traffic accidents, reduce environmental pollution, and improve traffic management and travel services. Chemical, intelligent, social, and human level.
(1) Traffic information collection system
The traffic information collection system consists of three parts: front-end detection equipment, communication equipment, and command center management system. The advanced traffic information collection system can grasp the current traffic operation status and predict the future traffic conditions, greatly improve the traffic efficiency and realize the intensive development of transportation. The traffic flow detection system uses microwave, coil and video detection technology to detect the traffic flow, occupancy rate, speed and vehicle traffic information of the current road section, and obtain the traffic flow status on each monitoring section in real time to judge the traffic congestion. Occurs, promptly provided to the traffic control department, to take appropriate shunt guidance, information prompts and other means to adjust.
(2) Traffic guidance system
The traffic guidance system consists of an outdoor display, a command center control system, and a communication system. Focus on key road sections such as urban main roads, set LED-induced display cards, reuse traffic data collected by electronic jing inspection and bayonet systems, and generate guidance information for public release after processing through the traffic management integrated application platform. Automatically generated or published after manual confirmation.
(3) Intelligent Traffic Management Platform
The intelligent traffic management platform is a unified information platform for urban traffic command system, which realizes information exchange and sharing, rapid response decision-making and unified dispatching command. Through the analysis and processing of collected static and dynamic data, traffic management control and induction are implemented, traffic incidents are processed in time, and traffic information is released to traffic participants through various channels. Following the requirements of the Technical Specifications for the Construction of Gong'an Traffic Command System (GA/T445-2010), the integrated platform is functionally divided according to different business needs, which constitutes the integrated command platform as the core, with road condition monitoring, traffic signal control, and inspection. Related functions such as control, information service, and business management are components, namely, a command and dispatch platform and five business application systems.
