Embodiment Construction

[0039] When current flows through a conductor, a magnetic field is formed around the conductor; when an alternating current passes through a conductor, an alternating electromagnetic field is formed around the conductor, called electromagnetic waves. When the electromagnetic wave frequency is lower than 100khz, the electromagnetic wave will be absorbed by the surface and cannot form effective transmission, but when the electromagnetic wave frequency is higher than 100khz, the electromagnetic wave can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere to form a long-distance transmission capability , we call high-frequency electromagnetic waves with long-distance transmission capabilities radio frequency. Radio frequency wireless power supply technology is to convert electric energy into radio frequency electromagnetic waves and emit them to form long-distance transmission capabilities. The load end converts this electromagnetic wave into...

Abstract

The invention discloses a tower radio-frequency power supply method and device. The tower radio-frequency power supply method comprises the steps that a communication module acquires load electricityparameters and load position information; a directional transmitting module is turned to the direction of the load position information according to the load position information; according to an electromagnetic induction principle, electric energy signals are acquired and transmitted to a radio-frequency conversion module; the radio-frequency conversion module converts the electric energy signalsinto first radio-frequency current signals, and the first radio-frequency current signals are transmitted to a power amplification module; the power amplification module amplifies the first radio-frequency current signals according to the electricity parameters to obtain second radio-frequency current signals and transmits the second radio-frequency current signals to the directional transmittingmodule; the directional transmitting module converts the second radio-frequency current signals into radio-frequency electromagnetic signals and transmits the signals to a load receiving module; theload receiving module converts the received radio-frequency electromagnetic signals into current signals for power supply of a load. Power is supplied for the load by adopting radio-frequency electromagnetic waves and the rotatable directional transmitting module, so that a power supply distance is longer, the power is enhanced, and charging of a portable electric device is achieved.

Description

technical field [0001] The present application relates to the technical field of electromagnetic wave power supply, in particular to a tower radio frequency power supply method and a device thereof. Background technique [0002] In recent years, the rapid growth of portable electrical equipment. This type of equipment also has the characteristics of high power consumption, and it is difficult to guarantee a long-term battery life by the battery storage of the equipment itself, and it is difficult to find a battery life for such electrical equipment mainly used outdoors. Due to the wide distribution area and vast territory of power towers, power sharing towers have incomparable advantages as the power supply for outdoor electrical equipment. [0003] The method of transforming and transmitting the electric energy in the power sharing tower to the power supply equipment is called the tower power supply method. The existing tower power supply methods are mainly traditional in...
