What is the development direction of intelligent building for postgraduate entrance examination?

Main listed companies in the intelligent building industry: Dashi Intelligent (00242 1), Yanhua Intelligent (002 178), CLP Xingfa (002298), Jiahua Technology (68805 1), Nanjing Panda (600775), etc.

The core data of this paper: coverage, business proportion and consideration factors.

Smart cities include smart buildings, smart public security and smart government affairs.

Smart cities include smart buildings, smart public security, smart government affairs, smart transportation, smart medical care, smart energy and so on. Among them, intelligent building is one of the important parts of smart city. Intelligent building can meet the requirements of high efficiency, energy saving, safety and comfort, and improve the information enjoyment ability of different systems. By optimizing the infrastructure in buildings, cities will be more sustainable, livable and efficient.

On behalf of the enterprise, it has transformed from an "intelligent building system integrator" to a "smart city solution provider"

In 20 13 and 20 14, the representative enterprises of intelligent building industry, Yanhua Intelligent, Dashi Intelligent and Yanhua Intelligent, began to transform from "intelligent building system integrator" to "smart city solution provider" respectively, and the proportion of enterprise intelligent building/intelligent building business decreased year by year. In 20 18 and 20 19, the proportion of yanhua intelligent building, Dashi intelligent building, intelligent building and energy saving decreased to 55.4% and 15.9% respectively.

20 18-20 19 yanhua intelligent building business is classified as other smart city services; From 20 19 to 2020, Dashi's smart medical care, smart transportation, smart community, smart building and energy saving businesses will be classified as solution businesses.

According to the description of listed companies, the layout of smart cities will bring certain performance uncertainty. Judging from the transformation effect, the gross profit margin of Yanhua Intelligent's other comprehensive smart city service businesses has increased compared with the intelligent building business. At the same time, Dashi's smart solution business includes smart medical care, smart transportation, smart community and other fields. Compared with 20 19, the gross profit margin of the business has not changed much.

Smart city ecosystem has great potential or is one of the factors of enterprise transformation. According to IDC data, in 20 18, the science and technology expenditure of smart cities in China reached 20.053 billion US dollars, which was the same as that of the first three application scenarios, followed by smart grid (belonging to elastic energy management and infrastructure), fixed intelligent video surveillance (belonging to data-driven public security governance) and intelligent bus system (belonging to intelligent transportation); By 2023, the proportion of the above three scenarios will drop to 37%, and the science and technology expenditure of smart cities will reach 38.923 billion US dollars.

Intelligent building is integrated into smart city ecosystem.

With the rapid development of artificial intelligence, Internet of Things, big data, cloud computing and other technologies, intelligent buildings, as an important part of smart cities, are expected to be integrated into the smart city ecosystem.

The factors that need to be considered in the integration of intelligent buildings into smart cities include: the determination of intelligent building architecture, the renewal of design concepts, the improvement of standards and specifications, and the construction of cloud computing service platforms.
