Wireless multi-way switch controller based on radio frequency identification and use method

Abstract

The invention discloses a wireless multi-way switch controller based on radio frequency identification and a use method, the controller changes a connecting line in the controller and a corresponding chip activation state through a multi-way switch device, and the on-off state of a multi-way switch can be identified through an RFID chip code read by a reader-writer. The controller is simple in structure, low in cost and convenient to process; the controller is completely passive and long in service time; the controller is small in size, does not need a power supply or wiring, can be conveniently attached to walls and furniture surfaces for use, and can be replaced at any time; the effective working distance is long, can reach more than ten meters and is not limited by the sight distance; a quasi-isotropic radiation mode is provided, the working frequency is kept near an FCC frequency band, and the performance can be kept stable at any angle or position; and the adaptability is high, and the controller and the driver can be randomly paired.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, and relates to a radio frequency identification-based wireless multi-channel switch controller and a use method. Background technique [0002] Wireless control technology has long been an integral part of industrial and domestic life. The current mainstream wireless control is based on traditional technologies such as infrared (IR), Bluetooth, and Zigbee. These techniques have obvious disadvantages: [0003] 1. A remote control (transmitter or gateway) can only control limited devices, so many controllers are required to cover all devices in an application scenario, which is not convenient in actual use; [0004] 2. Battery-driven controllers also have some disadvantages related to batteries, such as cost, limited working time and lifespan, and more importantly, the toxic pollutants contained in batteries take hundreds of years to degrade, which poses a threat to soc...
