The China Smart City Construction Industry Development Trend and Investment Decision Support Report divides the overall structure of a smart city into three levels: the perception layer, the interconnection layer, and the application layer. The sensing layer is the collection of information and is at the forefront of problem discovery; the interconnection layer is the acceptance of information, so that the accepted information is systematically interconnected; the application layer is the analysis of information, and finally the problem is solved intelligently. Program.
From the perspective of the perception layer, all information devices built in the city based on the sensing system will monitor the running status of the entire city in real time. The information that the sensor system returns to the big data supervision wisdom center is the value that the perception layer plays. The perception layer is in the basic part of the smart city, like the bottom of the pyramid, and is the cornerstone of the entire smart city. Only through the video image captured by the sensing layer, temperature and humidity, and even the information of the city's operating conditions can the interconnect layer and the application layer make the fastest and most accurate intelligent response. The interconnect layer and the application layer are more like the top part of the pyramid, which is the brain of a smart city. Through a series of analysis of the collected data, the valuable information is solved by the platform or means. This constitutes a complete smart city solution, and the overall smart city is constructed through a large number of uninterrupted sensing layers to the interconnection layer to the application layer.
Thus, the construction of a smart city can be understood as a process of interconnected, object-to-object. From the monitoring and guidance of road traffic congestion in urban traffic to the rapid identification of intelligent video in urban security; from the daily life of convenient and convenient life in urban life to the efficiency of government work in e-government and paperless office. These all make the city gradually intelligent, digital, and materialized. The most important value of a smart city is to serve the essence of "people." Whether it is transportation, environmental protection, people's livelihood, government affairs or life, it is built around a "people" to build a Z-good urban ecosystem.
