Industry 4.0, also known as intelligent industry + Internet, is a new stage of modern industrial information development. Some devices such as robots, UAVs, equipment monitoring, computers, industrial switches and data * are seamlessly combined through artificial intelligence, and industrial switches play the role of information transmission in the infrastructure of industrial Ethernet.

Based on Internet technology and big data as the engine, smart energy closely couples the power system with natural gas network, heating network, mining system, water system, industry, transportation and construction system for comprehensive collection, processing, analysis and application.

On the basis of intelligent transportation, intelligent transportation integrates high-tech IT technologies such as Internet of things, cloud computing, big data and mobile Internet, collects traffic information through high-tech, and provides traffic information services under real-time traffic data. A large number of data processing technologies such as data model and data mining are used to realize the systematicness and real-time of intelligent transportation, the interaction of information exchange and the universality of services.

According to the design idea of \"unified planning, unified standard, unified platform and unified management\", the \"intelligent community security system\" realizes the comprehensive perception of community data and events through video monitoring, micro bayonet, face access control and various IOT sensing devices in the community,
