Data acquisition extension control system and data acquisition method thereof

Abstract

The invention belongs to the technical field of data acquisition, and discloses a data acquisition extension control system and a data acquisition method thereof. A data acquisition host is used for acquiring data; a network card is connected with the Internet to carry out network data communication; a data analysis program is used for analyzing and processing the acquired data; an encryption algorithm is utilized to encrypt acquired data, an expansion program is utilized to expand a database of the acquired data, a cloud server is utilized to perform cloud storage on the acquired data, and adisplay is utilized to display a data acquisition expansion control system interface and acquired data content. The query performance of the database is improved; when the same data has a query request, a plurality of redundant data can share the pressure of the query request, so that the performance and the expansibility of the distributed database (only by simply adding computing nodes) are greatly improved, and the stability and the disaster tolerance are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, and in particular relates to a data acquisition extended control system and a data acquisition method thereof. Background technique [0002] Data acquisition, also known as data acquisition, is to use a device to collect data from outside the system and input it into an interface inside the system. Data acquisition technology is widely used in various fields. For example, cameras and microphones are all data collection tools. The collected data are various physical quantities that have been converted into electrical signals, such as temperature, water level, wind speed, pressure, etc., which can be analog or digital. The collection is generally a sampling method, that is, the data of the same point is repeatedly collected at a certain time interval (called the sampling period). Most of the collected data are instantaneous values, but also a characteristic value within a certain period...

AI Technical Summary

Problems solved by technology

[0006] The security of the existing collected data is low; at the same time, with the development of the Internet and the advent of the era of big data, more and more users access and the generation of massive data, the database capacity and concurrent access performance is poor

[0007] In the existing technology, the data collection speed is relatively slow, and the accuracy of collecting host data is poor, which is not conducive to the accuracy of further data analysis and processing results; the original algorithm data is set to be confidential, and there is a security risk in obtaining the data; the existing Technology cannot guarantee the accuracy of collected data, reduce the accuracy of stored content, and reduce the operating quality of the system

[0008] When the existing technology stores data, it needs to be encoded and calculated to generate redundant data, which affects the storage speed and efficiency of the system

When reducing the calculation amount of encoding during file storage, the actual binary encoding matrix construction process can only meet the tolerance and deletion performance of the storage system, and cannot reduce the calculation amount of the encoding process.
