Problems solved by technology

[0003] However, in this way, the real-time database needs to save all data, the data volume is huge, and the data query speed is relatively slow, especially for the later system expansion, adding more sub-stations, and adding more access points (data measurement sources) This problem is particularly prominent in

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0035] The first embodiment of the present invention relates to a distributed data access method of the Industrial Internet of Things, which allocates a sub-database for sub-stations distributed in different areas, and the remote communication device of each sub-station is connected to the bottom measurement point of the sub-station, including sensor Equipment and industrial control equipment, etc., receive the industrial data of this sub-station from the connected sensing equipment and industrial control equipment, and save it in the sub-database. Each sub-database saves the data of the measurement points under the jurisdiction of the sub-station. Each sub-database is connected to the main database through a wired or wireless network. ...

Abstract

The invention discloses an industrial internet-of-things distributed data access method and a database system. The method comprises the steps of allocating a sub-database to a measurement data source of a region, wherein each sub-database stores the data content of the region, and a main database stores an IP address and a data source range of each sub-database; when the main database receives a data subscription request from an application service, matching a data source range in the request with that of each sub-database, finding IP address/addresses of one or more matched sub-databases, and sending the data subscription request to the sub-databases; and after the data reported by the sub-database is received, returning the data to the corresponding application service. Therefore, huge data in an industrial internet-of-things system can be reasonably split and stored; the main database can quickly find an actual storage position of each piece of the data and call the data; while industrial internet-of-things application demands are met, the load of the main database can be reduced and the data search speed can be increased; and the database can be expanded infinitely and is smooth to upgrade.

Description

technical field [0001] The invention relates to a distributed data access technology of the industrial internet of things. Background technique [0002] The Internet of Things for industrial environment monitoring is generally widely distributed, and may be distributed in different regions of the country or even the world, with multiple sub-sites. Each sub-station generally includes: bottom-level sensor nodes, secondary industrial control equipment for data collection, sub-station monitoring center for real-time monitoring, summarization and analysis of data; monitoring centers of different sub-stations through the network (including public network, private network) etc.) finally access the general control center, and upload the collected data to the real-time database of the general control center. When various applications need to use data, they will request data from the real-time database of the main station. The source of the data is retrieved in the database, and the ...
