Home Smart Power Management System

technical field

The utility model relates to a home smart power management system, in particular to a home smart power management system combined with power signal modulation and demodulation, coupling, filtering and cloud device control systems.

Background technique

In today's society, the waste of household power resources is very serious. Except refrigerator, aquarium, god table lamp, and monitor needing 24-hour electric appliances in general households, there are also a large number of electrical appliances that do not need 24-hour electricity but are always plugged into the power socket. Since these electrical appliances are always waiting to start, the electrical appliances will still consume a small amount of electricity, such as TVs, computers, chargers, air conditioners and so on. According to the estimate of the International Energy Agency, there is about 3-11% waste in advanced countries. If you can develop the habit of pulling out the plug at any time, this saving is considerable. The current data communication methods used in remote control or remote control can be divided into two types: wired and wireless. Wireless communication does not need to be equipped with dedicated communication cables, but the ability to resist space electromagnetic interference is low; due to radio control constraints, it is sometimes impossible to control the duplex unit floor or a long distance within the limited transmission power range. Wired communication is highly reliable, but a dedicated communication cable is required. The power line carrier communication technology developed in recent years provides a new means of communication for remote control technology. The power line carrier communication uses the public power line and does not need to lay special communication cables, which simplifies the system, thus greatly improving the performance and price ratio of the design and manufacture of the home power intelligent management system. Although the power line carrier channel is the most direct and economical communication medium, there are various electromagnetic interferences in the power line, and effective means must be taken to eliminate them before they can be used. Especially in some developing countries, the interference sources of the power line power supply are numerous and serious. , Many power line data modem chips that can adapt to the United States and Europe cannot adapt to the AC power line power supply environment in developing countries in developing countries, and must be adapted to local conditions in terms of hardware filtering and software data modulation and demodulation.
