Description
Technical Field
The invention relates to the technical field of wireless power transmission of equipment, in particular to a sound wave wireless power transmission system with a positioning function and a control method.
Background
With the increasing demand for quality of life, people are increasingly pursuing application scenes that are going to be complicated and simple in life. The wireless power transmission technology is a hotspot of research in recent years, can realize the transmission of wireless energy, and helps people to get rid of the constraint of transmission cables.
First, it was thought that wireless transmission could be achieved by a scientist known as "father of alternating current", nigula tesla, who made a tesla coil to complete the task of lighting a lamp. For later practical reasons, this assumption has not been realized. In 1978, the precedent of wireless power transmission for electric vehicles was opened by george and bogel, americans. The technology has great development potential when developing to the current wireless power transmission mobile phone.
The application principle of the existing wireless power transmission technology is mainly an electromagnetic induction type and a nuclear magnetic resonance type, the physical placement position of equipment is required to be consistent with a power transmission end at a certain angle during power transmission, the technology has the problems of easy energy loss, low power, weak directivity, short power transmission distance and the like, and the generated electromagnetic radiation generates heat effect on human bodies.
Compared with electromagnetic induction and nuclear magnetic resonance type energy transmission, ultrasonic wave is a sound wave with frequency higher than 20000Hz (hertz), and energy is easier to concentrate due to short wavelength and directivity. Ultrasonic energy propagates in a variety of different media and can propagate far enough distances.
Disclosure of Invention
The invention aims to provide an acoustic wave wireless power transmission system with a positioning function and a control method thereof, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a sound wave wireless power transmission system with a positioning function and a control method are characterized in that: the system comprises a sonar positioning system, a power supply system, an ultrasonic generator, a transducer (converting electric energy into sound waves) in a power transmission and transmission module, a sound wave receiver and a sonar response system in an equipment receiving module, the transducer (converting sound waves into electric energy) and an equipment power supply system. When the equipment enters the sound wave coverage area, the sonar positioning system identifies and positions the equipment, specifically identifies the identity of the equipment and the sonar response system of the equipment, and sends a power-on instruction after the equipment is successfully paired, and at the moment, a servo motor in the equipment drives the sonar responder to adjust the receiving position. The sound wave generator obtains electricity through a socket or a power system of a building, converts electric energy into a high-frequency alternating current signal matched with the energy converter, drives the energy converter to work, and directionally aims at the vehicle to emit ultrasonic energy. When sound pressure acts on a sound wave receiver in the vehicle receiving module, the generated mechanical potential energy converts mechanical vibration into current through the energy conversion device, and power is output to equipment. When the equipment leaves the power transmission area, the sonar system receives the vacancy information, transmits the judgment result to the power supply controller, and turns off the power supply.
The specific implementation process comprises the following steps:
in the power transmission transmitting module, a sonar positioning system is always in an open state, the sonar response system built in the equipment is searched, the ID of the sonar response system is identified, the equipment enters and exits a power transmission area and the power of a battery of the equipment is judged, and the sonar system of the transmitting module sends a command of opening or closing a power supply according to a returned result of the judgment. Meanwhile, a servo motor in the receiving module can drive the sonar responder to adjust the position in real time so as to achieve accurate positioning.
When the equipment enters a power transmission area, the sonar positioning system in the transmitting module identifies the equipment ID, sends a power supply starting instruction to the power supply system, and the ultrasonic generator converts the received electric energy into a high-frequency alternating current signal matched with the transducer to drive the transducer to transmit sound waves to the equipment.
Meanwhile, a sonar positioning and identifying system in the transmitting module interacts with the wavelength through sonar frequency and takes the sonar frequency as a judgment basis for the output power, and the sound wave frequency band is adjusted.
When the sound pressure acts on the sound wave receiver in the vehicle receiving module, mechanical potential energy is generated, the transducer at the receiving end is utilized to convert the mechanical vibration energy into current, and power transmission is carried out on the equipment power supply system.
When the equipment leaves the power transmission area, the sonar positioning system judges that the equipment leaves when the sonar response system ID embedded in the equipment cannot be identified, and transmits a judgment result to a power supply control system in the transmitting module to turn off the power supply.
