Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0060] figure 1 It schematically shows the networked implementation scheme of online tracking of electrical equipment status. The overall process includes three steps: distributed data collection S101, communication network transmission S102, energy efficiency parameter analysis and state tracking operation S103. The implementation of S101 distributed data acquisition is divided into voltage acquisition unit, current unit and voltage and current mixing unit. Different from the existing disclosed methods, the measuring device provided by the present invention is aimed at low-cost measuring points without an independent receiving time service device. There are two schemes in the existing t...

Abstract

The invention relates to the field of communications and discloses an online tracking method and device of user equipment states. The device comprises a voltage sensing unit, a current sensing unit, a data collection unit, a data storage unit, a statistical analysis unit, an online tracking kernel (comprising a status recognition and tracking unit and a CPU (central processing unit)), an UART (universal asynchronous receiver/transmitter) debug port and a human-machine interface. The device tracks user equipment states online and processes signals; processed signals are tracked by means of iterative frequency scanning; sensing measuring devices and communication devices are integrated, state tracking signal processing is adopted, and online load running state can be tracked and recognized without large-scale wire removable, power outage and production halt; a WIA wireless communication unit is used for field collection; the online tracking method and device has the advantages such as low cost and convenience in deployment.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and device for online tracking of the status of electrical equipment. Background technique [0002] In order to improve the efficiency of electric energy utilization and promote the optimal allocation of electric power resources, the National Development and Reform Commission has formulated the "Power Demand Side Management Measures", which aims to improve the utilization efficiency of electric power resources through demand side management, so as to achieve scientific, economical and orderly use of electricity. Electricity. As a technical means to achieve the goal of energy conservation and emission reduction, the energy efficiency information system has gradually attracted widespread attention. The medium and low voltage distribution network is an important part of the power grid and the key to energy saving and consumption reduction of the power grid. The purpose of the...
