Resident smart power utilization management system and device based on 3rd generation telecommunication (3G) network

Abstract

The invention relates to a resident smart power utilization management system and a device based on a 3rd generation telecommunication (3G) network. The system comprises a household appliance, a smart power utilization device, the 3G network, a long-distance application server and a power utilization interactive terminal, wherein the smart power utilization device is connected with a power supply return circuit between the household appliance and an attaching plug in series, is communicated with the household appliance through an infrared method or an RS-485 bus, and is communicated with the power utilization interactive terminal through the 3G network and the long-distance application server. The purposes of smart power utilization management and control on the household appliance are achieved. The smart power utilization device comprises a master control module, an analog/ digital (A/D) sampling unit, a smart power utilization unit, a load control relay circuit, an RS-485 interface, and a plug and play 3G communication and cascading communication unit, and has the functions of power quality monitoring, electric energy measuring, load control and 3G communication. The problem that the service life of the household appliance is relatively long while the service life of a communication product is relatively short is solved, and the purpose that the smart power utilization device can effectively control the household appliance for a long time is achieved.

Description

technical field [0001] The invention relates to an intelligent electricity management system and device, in particular to a 3G network-based residential intelligent electricity management system and device. Background technique [0002] Smart electricity consumption is an important part of the smart grid. The construction of a smart grid requires encouraging and promoting users to participate in the operation and management of the power system. With the continuous advancement of the development of the smart grid and the continuous expansion of the scale, more and more attention has been paid to the smart electricity consumption of residents. . People hope to choose the power consumption time of household appliances reasonably by combining their own electricity demand and the load status of the power system through information technology. The smart grid balances the relationship between supply and demand by cutting peaks and filling valleys. Users can realize economic consum...
