Problems solved by technology

The most widely used at home and abroad is the PI real-time database. The compression method used in this database is the revolving door compression algorithm, but this algorithm has shortcomings: 1) The compression parameter ΔE is manually set by experience, and ΔE is set too large or Too small will seriously affect the compression rate and compression accuracy of historical data
2) During the data collection process of the power system, there will be noise data due to errors and abnormal data due to equipment failures, which will also reduce the compression effect of historical data

Embodiment Construction

[0020] Such as figure 1 As shown, the power monitoring system is divided into three modules, which are man-machine interface module, real-time database and communication module.

[0021] The man-machine interface module is a module for remote interaction between users and power facilities, and it is divided into user management module, project management module, component management module, and Gis map. User management, staff with different roles have different permissions, and the operations performed are different according to different permissions. The system administrator has the authority to project management, static resource management, and equipment fault management. Equipment maintenance personnel have the authority to view equipment operation status, equipment fault handling, and form filling. General operators have the authority to add and edit projects and manage equipment status.

[0022]Project management is mainly to create different projects according to the...

Abstract

The invention relates to a power monitoring system based on a real-time database, and belongs to the field of power monitoring system, which is divided into three modules, namely, a man-machine interface module, a real-time database and a communication module. The least square method is used to detect the abnormal data, smooth the abnormal data, and then compress the preprocessed data by the rotary door compression algorithm. The electric power monitoring system adopts the three-level storage mode of memory database, history database and disk storage to realize the real-time database. In the technology of real-time database, On the basis of guaranteeing the accuracy of historical data compression, The least square method is used to detect abnormal data, and the abnormal data is smoothed toavoid the adverse effect of abnormal data on data compression accuracy and compression efficiency, and then the rotary door compression algorithm is used to compress the preprocessed data, so as to improve the data compression rate and reduce the waste of storage space.

Description

technical field [0001] The invention belongs to the field of electric power monitoring systems, in particular to an electric power monitoring system based on a real-time database. Background technique [0002] With the development of information technology, computer technology, network technology and communication technology are widely used in various fields, and informatization plays an important role in the development of the global economy. The Internet of Things, as the third wave of the development of the world's information industry after computers and the Internet, has promoted the further rapid development of informatization. The Internet of Things technology is actually an integrated technology, involving various technologies such as sensing technology, radio frequency technology, communication technology, Internet technology, cloud computing, big data technology, and automation technology. The core and foundation of the Internet of Things is still the Internet, wh...
