Intelligent electric energy meter on-line monitoring and remote control system

Abstract

The invention discloses an intelligent electric energy meter on-line monitoring and remote control system. An automatic monitoring detection system comprises an electric energy meter verification device, a network camera, an Ethernet switch, and a meter hanging rack. An automatic load control system comprises a network relay and a host computer control system. A protection system comprises an air switch. The electric energy meter verification device comprises a computer, a signal source, a programmed control power source, a standard electric energy meter, and an error processor. An RS-485 bus way is adopted by communication among various modules in the verification device, and a signal source is used for the unified control of the working of the various modules. An RS232 interface is adopted for the communication between the electric energy meter verification device and a host computer, and the host computer is used to control the meter calibration working of the verification device. Error acquisition operation, determining operation, rounding operation, storage operation, and printing operation are completed at the same time. The real-time on-line monitoring and the remote control of the intelligent electric energy meter are realized effectively and accurately.

Description

technical field [0001] The invention relates to an online monitoring and remote control system of an intelligent electric energy meter. Background technique [0002] As a pillar industry of the national economy, electric power enterprises are characterized by the fact that power plants generate power, power supply departments supply power, and users consume electricity to form a large system. In this process, electricity is produced, sold and used as a commodity. Electric energy metering is the "weighing pole" for electric energy to be exchanged as a commodity, and it is the basis for assessment and economic settlement between power companies and power customers, power grids and power plants, and grids and power grids. The accuracy of electric energy metering is closely related to the economic interests of both the supply and demand sides of the power system. [0003] Electronic energy meter is an important tool for energy measurement, which is related to the interests of ...
