Problems solved by technology

At present, the databases used in the environmental protection industry are all real-time databases, and the data is stored on the disk. The establishment and use of the database are closed, which is not conducive to users adding monitoring points or modifying data query data.
The demand for real-time monitoring in the environmental protection industry is becoming more and more obvious. Choosing a traditional database faces the disadvantages of large data interaction and high system load.
At the same time, due to the large number of environmental protection monitoring points, the cost of selecting a real-time database (calculated by point) is very high

Embodiment Construction

[0023] The dynamic memory mapping database of the present invention establishes a multi-level storage mode to store data in the computer memory. Each level of storage structure includes multiple nodes and free memory areas. The nodes of the same level are respectively connected to the nodes of the upper and lower levels. The mapping relationship is established, and users access the lowest level data according to the mapping relationship. Such as figure 1 As shown, the memory mapping mechanism is established, and the basic data elements with a fixed memory size are customized according to the mode settings of the environmental protection system monitoring sub-stations, monitoring points, and data collections. In this mechanism, each main dimension node memory address corresponds at least For the memory address of a secondary dimension node list, the memory address of each secondary dimension node corresponds to at least one data heap memory address, and the data heap contains seve...

Abstract

The invention discloses a dynamic memory mapped database. Data is stored in a computer memory by establishing a multilevel storage mode, a storage structure in each level comprises a plurality of nodes, and the nodes in the same level respectively establish a mapping relation with the nodes in the previous level and the next level; and a user accesses the data in the lowest level according to the mapping relation. The invention also discloses a method for establishing, modifying and inquiring the database. The invention can be used for the real-time storage of environmental-friendly monitoring data. By adopting the invention, the user can add or delete the nodes, modify and store the data and inquire the data at mass according to requirements so that the use is convenient, and the working efficiency is high.

Description

Technical field [0001] The invention relates to a database for environmental protection industry monitoring, in particular to a database with dynamic memory mapping. The invention also relates to a method for managing the above-mentioned database. Background technique [0002] In recent years, the country has paid more and more attention to the environmental protection industry. Due to the increase in productivity, the discharge of environmental pollution factors such as sewage and waste gas has increased significantly. The requirements of sustainable development strategy goals make it imperative to increase environmental protection efforts. At present, the databases used in the environmental protection industry are all real-time databases, and the data is stored on disks. The establishment and use of databases are closed, which is not conducive to users to increase monitoring points or modify data query data. The demand for real-time monitoring in the environmental protection in...
