Method for searching data target on basis of spatial-temporal database

Abstract

The invention relates to a method for searching a data target on basis of a spatial-temporal database. The method is characterized by comprising the following steps: according to the temporal state and the spatial state of a target to be managed, performing modularization on the managed target; according to a management model of the target to be managed, setting a specific attribute which is described by using a natural language, of the target to be managed; on the basis of the type of the management model of the managed target, and a temporal attribute and / or spatial attribute which is defined by modularization and is described by using the natural language, performing retrieval, so as to confirm the operation state of the managed target. According to the spatial-temporal database, data information of production monitoring management is described by using three sections of times of history, real time and planning, a user does not need to master a computer language, but only with a spatial-temporal meta language, spatial-temporal data of the managed target can be retrieved and understood, and the spatial-temporal operation state of the managed target can be understood, namely both computer content can be saved and management is facilitated.

Description

technical field [0001] The invention relates to the field of computer retrieval, in particular to a retrieval method for data objects based on a spatio-temporal database. Background technique [0002] Among the research results at home and abroad, most of the spatio-temporal database models are in the process of theoretical research, and there are still few prototype systems that have been realized. At present, the main spatiotemporal database models mainly include: sequence snapshot model, spatiotemporal cube model, ground state correction model, spatiotemporal composite model, object-oriented spatiotemporal model, etc. These models have different properties and advantages and disadvantages, but none of them are well suited to the needs of the statistics industry. For example, the sequence snapshot model is composed of a series of time slices, each time slice represents the state of the map at different times, it can also be understood as a set of atlases with the concept ...

AI Technical Summary

Problems solved by technology

However, the problems in this patent are: (1) the relational database is SQL or oracle, which can only be classified and retrieved through coding, and cannot be retrieved and queried by directly inputting time or space information (quick retrieval of historical databases can only be done through time information, and cannot be retrieved through spatial information), so it is very inconvenient to query and call the database; (2) the retrieval method is single, and can only be retrieved within a certain time range, but not within a certain spatial range. For example, it is not possible to retrieve information on all disasters that occurred in the Pacific region

However, the problems in this patent are: (1) The accuracy and precision of the spatial description is not high enough, for example, the upper and lower parts of a certain equipment in the factory cannot be described accurately and differentiated; (2) The query of data by spatial analysis and coding It is inconvenient to call, for example, to check the working status of the boiler in the factory, 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

At present, there is no database that can improve the functions of these types of databases, and it can be configured and realized
