But in fact, I do not know enough about the basic information of the smart city, here for their own understanding, from the basic provisions to the interpretation of the term, from the beginning of the comb.
-----------------------
I. Terminology Interpretation
CIM (City Information Model/Modeling) City Information Model
BIM (Building Information Model/ Modeling) Building Information Modeling
GIS (Geographic Information System) Geographic Information System
WMS (Web Map Service) Network Map Service
WCS (Wbe Coverage Service) Network Coverage Service
S3M (Spatial 3D Model) Spatial 3D Model
I3S (Indexed 3D Scene) Indexed 3D Scene
BAS (Building Automation System) Building Automation System or Building Equipment Automation System
IBMS ( Intelligent Building Management System) IBMS (Intelligent Building Management System) intelligent integrated system, refers to the BAS on the basis of further communication network systems, information network systems to achieve a higher level of integrated building management system
IOT (Internet of Things) Internet of Things, also known as the sensor network, briefly speaking Is the extension of the Internet from people to things
IOC (Inversion of Control) directly translated is "control reversal", explaining that the complex system is decomposed into objects that cooperate with each other, these object classes through the encapsulation, the internal realization of the external is transparent, thus reducing the complexity of the problem. This reduces the complexity of problem solving, and can be flexibly reused and extended. Mapped to the smart city, it is the decomposition of each system into functions that can be combined, and these functions can be called by the upper application system through the ioc
AIOT = AI (Artificial Intelligence) + IoT (Internet of Things), AIoT fusion of AI technology and IoT technology, through the Internet of Things to generate, collect from different dimensions of the massive amount of data stored in the cloud, edge, and then analyze and analyze big data, and higher forms of data, and then analyze and analyze big data, and higher forms of data. Big data analysis, and higher forms of artificial intelligence, to achieve everything data, everything intelligent connection
Second, the general provisions
1, the overall architecture of the platform should include the bottom-up facilities layer, data layer, service layer, as well as the standard specification system, operation, maintenance and security system; the upper layer of the three levels of the lower level has a dependency, the two major systems have a constraints on the three levels. The two systems have constraints on the three levels.
2, the platform facilities layer should include data collection, transmission, storage, processing, services and other basic software and network resources.
3, CIM infrastructure platform construction to unify the management of CIM data, provide data and service access interfaces to meet the requirements of business collaboration, information linkage and application extension.
3, national, provincial and municipal CIM platform interface:
1, CIM infrastructure platform is divided into national, provincial and municipal platforms, three platforms to achieve network connectivity, data **** enjoyment, business synergy.
2, the national, provincial and municipal platforms to establish synergistic working mechanism and operation and management mechanism, the vertical relationship between the three:
1), supervision and guidance: to support the monitoring and supervision, notification and release, emergency management and guidance applications;
? 2）、Operational synergy: support special actions, key task implementation and briefing applications;
? 3）、Data ****sharing: national, provincial and municipal platforms should carry out data ****sharing with the same level of government system, as well as realize cross-platform data ****sharing.
? 4) The national platform and provincial platforms should have the functions of important data collection, data query and visualization, statistical analysis, data *** enjoyment and exchange, monitoring and supervision, operation management and development interface.
Today, we will stop here, and tomorrow we will continue to organize the general specifications for data visualization, data query, and data interface.
