Embodiment Construction

[0038] In order to make the object, technical solution, and advantages of the present invention clearer, actual examples are given here and further descriptions are given with reference to the accompanying drawings.

[0039] The present invention conducts a detailed demand analysis on the HBase-based oil well information query system by combining the characteristics of the oil well data and the project background. Design and implement a query system that supports various oil well information according to the requirements. The system administrator uploads and loads different data into the system, and the user can quickly obtain data information such as oil well temperature, salinity, and density in the selected area by setting the range of conditions such as time and latitude and longitude.

[0040] This paper designs and implements an R-tree spatial index on HBase. Compared with other data materials, combined with the existing data format and HBase technical analysis, HBase i...

Abstract

The invention relates to a quick query method of position information on the basis of a space index technology. The method comprises the following steps that: according to target space coordinate information to be queried, establishing an R tree space index, establishing R tree node mapping on an HBase database, and forming a space index database; according to a minimum boundary rectangle formed by user input coordinate information, carrying out query in the space index database; and returning a query result to the user. By use of the method, an R tree space index technology can be adopted to realize the quick query of a space coordinate. A bottom layer adopts the HBase database as a storage medium, the parallelization of a query task can be realized, and query performance is improved. Information including oil spill and the like can be accurately positioned. In addition, compared with a traditional method, the quick query method is characterized in that query performance is obviously improved, and is suitable for system development which aims at oil field or ocean data coordinate information query.

Description

technical field [0001] The invention relates to a quick search method for location information based on spatial index technology, which belongs to the field of intelligent manufacturing control. Background technique [0002] In recent years, various data management technologies have been constantly innovating. Among them, the Hadoop open source product series has been widely recognized in commercial practice and has almost become the de facto big data management industry standard platform. One of the main features of the Hadoop cloud computing platform is that it can provide scalable computing power and storage capacity, and the realization of interactive data query is also the concern of users, which is the key factor for the success of cloud computing. As a NoSQL storage system, HBase is specially designed for fast random read and write of large-scale data. As a sub-project of the Apache Hadoop project, a distributed, column-oriented open source database, HBase is differe...
