Problems solved by technology

[0004] A significant disadvantage of the existing mainstream development methods is that the collection and fusion of multi-source heterogeneous data needs to be customized and developed according to specific product business requirements, which is costly; most of the business relationships between data from different sources cannot be dynamically updated after the system goes online. Adjustment makes it difficult to evolve and upgrade system functions, and the analysis dimensions that can be processed are limited within the scope of the initial design of the system
In addition, the association analysis of time, space and specific business data is a necessary condition for the normal operation of the smart city system, but the existing conventional data processing technology solutions cannot seamlessly integrate geographic information data, time data and various heterogeneous business data

Embodiment 1

[0132] see figure 2 , Embodiment 1 of the present invention provides a data association and analysis method in a city information model, which is used to realize data association and analysis of multi-dimensional and multi-association relationships among objects in the city information model. The IT system implemented by the method of the present invention can theoretically perform data analysis with unlimited dimensions and unlimited relationship types for entity objects in any city information model.

[0133] The data analysis method comprises the following steps:

[0134] (1) Use the relation type definition (RelationTypeDef) to describe the various properties and different types of abstract associations between the entity objects that need to be expressed in the city information model. For example, the containment relationship of two entity objects in space, or the logical dependency relationship of two entity objects.

[0135] Among them, an unlimited number of relations...

Embodiment 2

[0145] see image 3 , Embodiment 2 of the present invention provides a time-space integrated multi-dimensional data association method in a city information model. The global dimension type definition can establish an association relationship with all object entities in the city information model through a unified operation method, by pre-adding a special global dimension type definition expressing time and space concepts and linking it with other city information model object entities Mixed use can realize the multi-dimensional data analysis function of time and space integration. Using the global dimension type definition combined with the object type definition realizes the spatial-temporal integration multi-dimensional data association in the city information model.

[0146] The global dimension type definitions include:

[0147] (1) Define the global dimension type definition representing the time dimension, including defining the year (Year Dimension), month (Month Dim...

Embodiment 3

[0154] Embodiment 3 of the present invention provides a method for implementing multi-source heterogeneous data analysis in a city information model, the method comprising:

[0155] (1) Use the object type instance (InfoObject) as a digital mirror image describing various business objects in the city information model, the object type instance is the real data expression of a specific object type definition, and the object type definition represents the city A type representation of any entity object that can be contained in an information model.

[0156] (2) Obtain all data information related to the business object through the object type instance.

[0157] (3) The attribute set is used as the minimum unit for describing business data grouping in the object type instance, and all operations on data must be realized by accessing the attribute set. By using attribute sets with different structures, the integrated access and analysis of multi-source heterogeneous data with att...

Abstract

The invention discloses an analysis, association, storage and access method and device for data in a city information model, and the method comprises the steps of achieving the data analysis among objects in the city information model through employing a relation type definition, an association relation instance definition, an object type definition, a global dimension type definition, an attribute type definition, an attribute set definition, an operation set and an attribute set definition data type; the invention can support complex object type expression and internal data attribute definition, can perform complex multi-dimensional association, can integrate various types of external data sources seamlessly and transparently, and support the urban scale-level mass data storage capacity.

Description

technical field [0001] The invention relates to the technical field of data fusion and analysis, in particular to a method and device for analyzing, associating, storing and accessing data in a city information model. Background technique [0002] A city is composed of six core systems of different types of networks, infrastructure and environment related to the main functions of the city, including organization (people), business / government, transportation, communication, water and energy. These systems are not fragmented but interconnected in a collaborative manner. The city itself is a macro system composed of these systems. Smart City (Smart City) refers to the use of various information technologies or innovative ideas to integrate the constituent systems and services of the city to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens. From the perspective of technological development, the ...
