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

Embodiment 1

[0050] Take the spatial attribute description and search of things as an example. The method of describing the spatial attributes of things is to realize the spatial information labeling according to the spatial state of the object to be described. The spatial attributes of the things to be described are based on the self-defined multi-level structure of the production industrial process; the upper-level spatial object is the parent object of the secondary spatial object, and the secondary spatial object is the child object of the upper-level spatial object; Child objects have a parent object that includes at least one child object. For example, if the thing to be described is a group company, the spatial granularity is divided into head office, branch factory, workshop (warehouse), production line, process, workstation, equipment, etc., among which, Google Maps or Baidu map, and choose to set the corresponding coordinate system in the map configuration, draw a root root node...

Embodiment 2

[0056] Taking the spatio-temporal database in the process of factory production as an example to illustrate the time and space modeling of production data. A time model, a space model and / or a space-time model are respectively established according to the time state and space state of each object to be managed.

[0057] Time model: the time model is a data model used to describe the time state of the object to be managed. The time granularity of the time model is the unit to measure the time status, including time units and custom time parameters based on production conditions. Preferably, the time model is a model describing the time granularity of the object to be managed. For example, the time granularity is year, month, day, hour, minute, or second. You can also customize the time granularity, such as shifts or batches.

[0058] Space model: the space model is a data model used to describe the space state of the object to be managed. The spatial granularity of the spat...

Abstract

A method for describing the spatial attributes of things and searching based on the description, the method for describing the spatial attributes of things is to realize the spatial information labeling of the objects to be described according to the spatial state of the objects to be described, specifically: loading through a spatial object editor Electronic map, and set the coordinate system for the electronic map, and draw a spatial range of the root node based on the geographic location of the thing to be described, and draw a spatial object within the range of the root node with rectangles, irregular polygons, points, and polylines. Obtain the first-level spatial object of the thing to be described; based on the upper-level spatial object, use rectangles, irregular polygonal lines, points, and polylines to realize the spatial drawing process of the constituent elements of the thing to be described step by step to obtain the corresponding level of the constituent elements Spatial object: match the spatial state of the thing to be described with the spatial objects of all levels in the spatial object, so as to realize the spatial information labeling of multi-level and / or multi-level things to be described.

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...
