Home appliance information communication system of asymmetric power line carrier and wireless communication

Abstract

The invention provides a home appliance information communication system of asymmetric power line carrier and wireless communication. The system comprises an electric energy meter gateway, a ZB-APLC (zinc borate-active power line conditioner) and a white information home appliance, wherein the white information home appliance comprises an APLC standard white information home appliance and a ZigBee standard white information home appliance; an APLC communication circuit of the APLC electric energy meter gateway is arranged in an electric energy meter, and the APLC electric energy meter gateway is accessed between a phase line and an N phase of a three-phase four-wire system at a lower voltage side of a 10kV / 0.4kV distribution transformer of an electric power system; a ZB-APLC network bridge is electrically connected with the load of the white information home appliance, and the ZB-APLC network bridge is accessed into the electric system by the APLC electric energy meter gateway; digital communication is performed between the APLC electric energy meter gateway and the ZB-APLC network bridge by the asymmetric power line carrier communication, the communication between the APLC electric energy meter gateway and the ZB-APLC network bridge adopts a voltage type FSK (frequency shift keying) or S-FSK (spread frequency shift keying) modulating signal, and the communication between the ZB-APLC network bridge and the APLC electric energy meter gateway adopts a current type FSK or S-FSK modulating signal; and the information exchange between the ZB-APLC network bridge and the ZigBee standard white information home appliance can be realized by the ZigBee wireless communication.

Description

Home appliance information communication system based on asymmetric power carrier and wireless communication technical field The invention relates to a home appliance information communication system for home users or unit users using power line carrier and wireless communication. Display and control of energy, electric power, water volume, gas volume, time, leakage protection, open circuit load control, tariff, etc. At the same time, the bridge communicates with household appliances and measuring instruments used by users through wireless ZigBee (communication standard adopts IEEE802.15.4) standard for wireless communication. Asymmetric power line carrier communication, abbreviated as: APLC (Asymmetric Powerline carrier). Background technique For the current centralized meter reading system of power line carrier electric energy meters, see accompanying drawings 1A and 1B. The electronic watt-hour meter is a kind of electric energy meter. The power carrier concentrator (...
