Key technologies and overall solutions for smart cities

Through a new generation of informatization technology, smart cities will enhance the ability of city managers to perceive, analyze and process all aspects of information in the city, thereby further providing targeted new services and new models. The application solutions for “smart cities” based on diversification, high-definition and intelligence will support the core technology of smart city construction.

According to forecasts, by 2020, half of China's population will live in cities, and by 2050, 75% of the population will live in cities. The rapid urbanization process has made important contributions to China's economic development. On the other hand, cities are also facing development in various aspects, such as environment, infrastructure construction, quality of life, population issues, public safety, and public services. bottleneck.

Smart cities are proposed in the context of restricted urban development and challenges facing transformation. Through a new generation of informatization technology, smart cities will enhance the ability of city managers to perceive, analyze and process all aspects of information in the city, thereby further providing targeted new services and new models. Safe cities are an indispensable part of smart cities. Dahua ’s diversified, high-definition and intelligent safe city solutions are a set of practical and effective solutions and practices for the transition from traditional cities to smart cities.

Several key technical analysis of "smart city"

The core of a smart city is to use a new generation of information technology to change the way city managers and residents interact with each other in a smarter way to improve the clarity, efficiency, flexibility, and response speed of the interaction. Overall, it should have at least three layers of architecture: perception layer, interconnection layer, and application layer.

Collect all-round information of the city through the perception layer, link various information systems through the interconnection layer for information interaction and sharing, and adopt intelligent technology through the application layer to deeply analyze the collected data to obtain more novel, systematic and comprehensive Insight to solve specific problems. From a technical point of view, the following basic technologies are necessary cornerstones for smart cities.

Perception technology

Perception here is a broader concept. Specifically, it refers to a device or system that more widely senses, measures, collects, and transmits information. By using these devices, any information from indoor temperature, humidity, smoke to road vehicle information, urban traffic conditions, etc. can be quickly obtained and analyzed, which is convenient for immediate response measures and long-term planning. As one of the most intuitive way of perception, video is widely used in cities. We believe that in the current and future urban applications, the development direction of video application solutions is diversified and high-definition. There are both analog high-definition video application solutions for social resources and IP network high-definition video for public security actual combat business. Application solutions, as well as HD-SDI lossless high-definition video application solutions for important urban control points.
