Object data subscription method based on spatiotemporal database

Abstract

The invention relates to an object data subscription method based on a spatiotemporal database, comprising an organizing process and a subscription process of data objects. The organizing process comprises a process of constructing a database of the data objects; the subscription process is a step of actively pushing information to the client associated with the database according to at least one data record change of the spatiotemporal database so that the user can know in time the running state of the desired object to be managed. The spatiotemporal database of the objects at least includes interaction among the real-time database, and the historical database and the planning database of the object data interacting with each other so as to timely transmit and monitor the running state of the objects during the automatic operation thereof.

Description

technical field [0001] The invention relates to an application method of a spatio-temporal database, in particular to a method for subscribing object data based on a spatio-temporal database. Background technique [0002] Data is the expression of information, and a large amount of production process data and business data need to be processed to obtain the implied information. The database has developed to this day and has experienced hierarchical, network, relational and non-relational databases. Database has become an essential system for data storage and query. Now, there are also some so-called spatio-temporal databases, mainly GIS (Geographic Information System) borrow relational databases for data storage. In the field of industrial production monitoring and management, there are SCADA monitoring, real-time databases, relational databases, and applications of open source non-relational databases. A relational database is a database built on the basis of a relationa...

[0005] Chinese patent CN103678712A discloses a space-time database of disaster information. The space-time database of disaster information includes three disaster information databases: disaster current situation database, disaster process database and disaster history database. The unified coding module encodes the received disaster information data hierarchically; attribute data management Module and spatial location data management module import disaster information attribute data and spatial location data to the corresponding disaster information database; disaster information data is transmitted between disaster information databases through logic change module; spatio-temporal database index module The database establishes an update index; the logical change module and the spatio-temporal database index module form the basis of the disaster information spatio-temporal database, manage and maintain the disaster attributes, change and maintain the spatio-temporal logical index, and prepare for the warehousing, retrieval and spatio-temporal query of statistical data; Solve the problems of high data redundancy and low work efficiency in the storage, management and historical review of spatio-temporal data

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 problem in this patent is that a specific identification code is required when querying and calling data in the database, and the time point or location point cannot be directly entered for query

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

[0015] In addition, in the prior art, the process of using the spatio-temporal database to retrieve information is a process that requires active understanding of relevant information, and real-time monitoring of objects is prone to omissions, resulting in poor real-time monitoring results.
