Method for describing space attributes of things and carrying out search based on description

Abstract

The invention discloses a method for describing space attributes of things and carrying out search based on description. The method for describing the space attributes of the things comprises the step of realizing space information labeling of to-be-described objects according to space states of the to-be-described objects, specifically, loading an electronic map through a space object editor, setting a coordinate system for the electronic map, drawing a space range of a root node based on geographical locations at which the to-be-described things are located, and drawing a space object through utilization of rectangles, irregular multilateral lines, points and broken lines in the root node range, thereby obtaining a first-level space object of the to-be-described things; on the basis of the last-level space object, realizing a space drawing process of composition elements of the to-be-described things level by level through utilization of the rectangles, the irregular multilateral lines, the points and the broken lines, thereby obtaining corresponding levels of space objects of the composition elements; and correspondingly matching the space states of the to-be-described things with all levels of space objects in the space objects, thereby realizing the space information labeling of the multilevel and / or multilayer to-be-described things.

Description

technical field [0001] The present invention relates to a method for monitoring and managing industrial projects or production, in particular to a method for describing the spatial attributes of things and searching based on the description. Background technique [0002] The database has developed to this day and has experienced hierarchical, network, relational and non-relational databases. The database has become an indispensable system for data storage and query. Now, there are also some so-called spatio-temporal databases, and GIS (Geographic Information System) mainly borrows relational databases for data storage. A relational database is a database built on the basis of a relational model, with the help of mathematical concepts and methods such as set algebra to process data in the database. Various entities in the real world and various links between entities are represented by relational models. The relational model refers to the two-dimensional table model, so a r...

Problems solved by technology

In the above scheme, the existing problems are: (1) The accuracy and precision of the spatial description is not high enough, for example, the upper part and the bottom of a certain equipment in the factory cannot be described accurately and differently; (2) The spatial analysis and coding for data query It is inconvenient to call, for example, to check the working status of a factory boiler, you need to find the code corresponding to the boiler, and you cannot directly query; (3) When the physical location is updated and changed, the database is not dynamically updated

However, the problem with this patent is that specific number identification information is required when querying and calling data. In some fields, such as the field of industrial process control, there are many types and quantities of equipment and process parameters, and it is very inconvenient to use numbers to query data
