Remote control system without standby power consumption based on radio frequency identification and remote control method

Abstract

The invention belongs to the technical field of wireless remote control and relates to a remote control system without standby power consumption based on radio frequency identification, comprising a remote control and at least one executor, wherein, the remote control is used for emitting radio frequency wave signal controlling the executor and receiving feedback signal from a controller; the executor is used for receiving radio frequency energy and the radio frequency wave signal from the remote control; on one hand, the radio frequency energy is converted into a direct current stable working voltage to supply electricity to the remote control system, on the other hand, corresponding control action is implemented by driving an electronic switch and each executing circuit according to control information carried by the radio frequency wave signal sent from the remote control. Meanwhile, the invention provides a remote control method adopted by the remote control system. By adopting the remote control system and the remote control method of the invention, the remote control system can be really and completely disconnected with commercial power under the state of appliance standby, thus achieving the purpose of energy saving.

Description

technical field [0001] The invention belongs to the technical field of wireless remote control, and relates to a remote control system. Background technique [0002] Wireless remote control refers to the non-contact remote control of the controlled object, which is widely used in the fields of industrial control, aerospace, and home appliances. The remote control system generally consists of two parts: the remote control and the actuator. The remote control is generally composed of command keys, command encoding circuits, modulation circuits, drive circuits, and transmitting circuits. The command coding circuit generates a corresponding command coding signal, and the command coding signal modulates the carrier wave, and then the power is amplified by the driving circuit, and then emitted by the transmitting circuit. The actuator is generally composed of a receiving circuit, an amplifier circuit, a demodulation circuit, an instruction decoding circuit, a drive circuit and a...

Problems solved by technology

[0009] Although the above traditional power supply standby power limitation method can reduce the standby power consumption of electrical equipment to a certain extent, since the electrical equipment is not completely disconnected from the mains in the standby state, these unnecessary energy losses cannot be fundamentally eliminated.
