Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
At present, the development of the radio frequency charging technology makes partial breakthrough, wherein the Wi-Fi charging technology makes key breakthrough, the conversion efficiency is improved to 40% to the maximum extent, and the charging of equipment through Wi-Fi signals becomes possible. However, radio frequency energy is limited by wireless device power limitations, requiring tight control of power consumption. For example, wi-Fi, which has relatively high power, is commercially available, and is limited by the power and coverage of wireless devices, and adopts an omni-directional antenna, and the total transmission power is limited to 200mW. In this case, the Wi-Fi signal can supply less electric energy, which cannot meet the charging requirement of a general device, and since the omni-directional antenna is used, the power is uniformly distributed in the space, and the utilization rate is low.
Referring to fig. 1, a radio frequency charging device according to an embodiment of the present invention includes: a transmitting end main control circuit 103 and a rotatable radio frequency charging antenna 107 connected with the transmitting end main control circuit 103; the rotatable radio frequency charging antenna 107 is configured to detect a current signal strength of a charging receiving end, and the transmitting end main control circuit 103 is configured to control the rotatable radio frequency charging antenna 107 to rotate according to the current signal strength; when the current signal strength reaches a preset strength value, the rotatable radio frequency charging antenna 107 stops rotating, the transmitting power is increased to a preset power, and radio frequency charging energy is transmitted to the charging receiving end according to the preset power.
According to the invention, by arranging the transmitting terminal main control circuit and the rotatable radio frequency charging antenna, the coverage area of the charging signal can be adjusted by rotating the rotatable radio frequency charging antenna, and under the condition that the charging receiving terminal moves, the charging receiving terminal can be subjected to radio frequency charging by using the optimal transmitting angle and transmitting power, so that the power limitation and the coverage area limitation are reduced, and the utilization rate of radio frequency energy is improved.
Specifically, the radio frequency charging device is a charging transmitting terminal, and the transmitting terminal main control circuit is a main body control circuit and controls the overall operation of the radio frequency charging device. The invention can be applied to the charging of common Wi-Fi, bluetooth, zigbee and other devices. The rotatable radio frequency charging antenna is a directional high-gain antenna and is used for radio frequency charging related functions, the rotation range is 360 degrees of left-right rotation on the horizontal plane, and 90 degrees of up-down rotation on the vertical plane, and therefore self-adaptive position finding is achieved.
The embodiment sets a preset intensity value for judging the intensity of the signal intensity. If the current signal strength is smaller than the preset strength value, the current signal strength is weaker, the radio frequency charging is not facilitated, and at the moment, the rotatable radio frequency charging antenna needs to be controlled to rotate until the current signal strength is stronger, so that the radio frequency charging efficiency is improved. When the current signal strength reaches a preset strength value, the signal strength is high at the moment, and the signal power can be maintained, so that the rotatable radio frequency charging antenna does not rotate any more, the transmitting power is enhanced to the preset power at the position, and the radio frequency charging energy is transmitted to the charging receiving end according to the preset power. The preset power may be a maximum power, i.e., a safety limit power.
In one implementation, the radio frequency charging device further includes: a transmitting end communication antenna 101, a radio frequency circuit 102, an antenna adjusting circuit 105 and an antenna rotation driving mechanism 106; the transmitting end communication antenna 101, the radio frequency circuit 102, the transmitting end main control circuit 103, the antenna adjusting circuit 105, the antenna rotation driving mechanism 106 and the rotatable radio frequency charging antenna 107 are connected in sequence; the transmitting end communication antenna 101 is used for relaying and forwarding radio frequency signals; the radio frequency circuit 102 is configured to relay the radio frequency signal forwarded by the transmitting-end communication antenna 101; the antenna adjusting circuit 105 is configured to receive an adjustment instruction of the transmitting end main control circuit 103, and perform angle adjustment and power adjustment on the rotatable radio frequency charging antenna 107; the antenna rotation driving mechanism 106 is configured to drive the rotatable rf charging antenna 107 to rotate under the driving of the antenna adjusting circuit 105. The radio frequency charging device further comprises: and the power supply circuit 108 is connected with the transmitting terminal main control circuit 103, and the power supply circuit 108 is used for supplying power to the radio frequency charging device.
Specifically, the transmitting-end communication antenna 101 is used for transceiving communication data, for example, when communicating with a Wi-Fi router, relaying and forwarding signals is realized. The radio frequency circuit 102 is used to relay the radio frequency signal, such as a Wi-Fi signal. The antenna adjusting circuit 105 can adjust the power of the rotatable rf charging antenna 107 and drive the antenna rotation driving mechanism 106 to adjust the angle and the orientation of the rotatable rf charging antenna 107. The antenna rotation driving mechanism can be selected as a motor, and the rotation function of the rotatable radio frequency charging antenna can be realized. The power supply circuit can be connected with a fixed power supply.
The working principle of the radio frequency charging device is as follows: the radio frequency charging device is used as a charging transmitting end in a radio frequency charging system, signal broadcasting is started at fixed power, signal feedback of a charging receiving end is monitored, meanwhile, the charging receiving end searches for a radio frequency signal of the radio frequency charging device and returns a signal intensity value of the signal. If the radio frequency charging device does not receive the signal feedback, the rotatable radio frequency charging antenna is driven to rotate, and the steps are repeated. And if the radio frequency charging device receives the signal feedback, obtaining a signal strength value, judging the distance and the approximate direction of the charging receiving end through the signal strength value, and rotating the rotatable radio frequency charging antenna according to the distance and the approximate direction until the signal strength value reaches a preset strength value. At the moment, the signal intensity is stronger, and the optimal charging emission angle is achieved. And if the preset intensity value cannot be reached, driving the rotatable radio frequency charging antenna to rotate to the position with the maximum signal intensity. Meanwhile, the antenna adjusting circuit increases the transmitting power (within a safe power range), enhances the charging signal and further realizes stronger charging signal charging. As shown in fig. 3 and 4, 401 and 402 are radio frequency signal coverage, where 401 is a signal coverage transmitted by the communication device 300 (e.g., a home Wi-Fi router), and 402 is a signal coverage transmitted by the radio frequency charging apparatus 100. When the charging receiving end 200 moves, for example, the state in fig. 3 changes to the state in fig. 4, the above steps are continuously repeated, and the pointing direction and power of the rotatable rf charging antenna are continuously adjusted to achieve the optimal charging transmitting angle and transmitting power, thereby achieving automatic tracking.
Therefore, the radio frequency charging device serves as a charging transmitting terminal, the problems that communication equipment is limited by power and coverage and the radio frequency energy utilization rate is low can be solved, the charging receiving terminal can be accurately charged, the coverage is expanded, and the charging power is improved.
The present invention further provides a radio frequency charging system, referring to fig. 2, fig. 3 and fig. 4, the radio frequency charging system includes: the rf charging apparatus 100 and the charging receiver 200 are described above. That is, the rf charging device 100 is a charging transmitting end, which can implement adaptive bit-finding and dynamic power adjustment; the charging receiving terminal 200 may be a low power consumption device terminal, and may implement feedback of signal strength and charging using radio frequency energy.
The charging receiving terminal 200 includes: a charging receiving antenna 205, a receiving end rectifying circuit 204, an energy conversion circuit 203, a receiving end main control circuit 202 and a receiving end communication antenna 201 which are connected in sequence; the charging receiving antenna 205 is configured to receive radio frequency charging energy, the receiving end rectifying circuit 204 is configured to convert the radio frequency charging energy into electric energy, the energy conversion circuit 203 is configured to receive the electric energy converted by the receiving end rectifying circuit 204 and supply the electric energy to the receiving end main control circuit 202 according to real-time power consumption, and the receiving end communication antenna 201 is configured to detect radio frequency signal strength in a space and broadcast a signal strength value.
Specifically, the receiving-end rectifying circuit 204 is composed of a rectifying diode and a radio frequency signal converter, and is used for energy conversion, that is, converting radio frequency energy into electric energy. The energy conversion circuit 203 receives the electric energy converted by the receiving end rectifying circuit 204, and supplies the electric energy to the receiving end main control circuit 202 according to the real-time power consumption of the system.
In one embodiment, the charging receiving end 200 further includes: and the lithium battery 206 is used for storing the electric energy converted by the receiving end rectifying circuit 204 and supplying power to the charging receiving end. That is to say, this embodiment can also be for lithium battery charging, and application scope is wider.
The working principle of the charging receiving end is as follows: the charging receiving antenna receives radio frequency signals in space, namely radio frequency charging energy emitted by the radio frequency charging device, and integrates and converts the radio frequency charging energy into electric energy by combining with a receiving end rectifying circuit, so that the whole equipment is driven to work. And when the received radio frequency charging energy is lower than the energy required by the system to work, the energy conversion circuit is driven to store energy. The energy storage can be realized by an energy storage capacitor, for example, a lithium battery is configured, and the redundant energy is transferred to the lithium battery for storage. When the energy is enough to drive the system of the charging receiving end to work, the radio frequency signal intensity in the space is detected through the communication antenna of the receiving end, and the signal intensity value is broadcasted.
The invention can be used in the fields of IoT intelligent home, intelligent wearable equipment and low-power-consumption equipment. Through the self-adaptive radio frequency charging system, the non-inductive real-time charging of low-power-consumption equipment is realized, and the maintenance cost of the equipment, such as charging, battery replacement and the like, is greatly reduced.
That is, the present invention implements an adaptive rf charging system, which includes a transmitting device and a receiving device. The transmitting end can dynamically adjust the transmitting direction and the transmitting power according to the position of the receiving end equipment; the receiving end can detect the signal intensity of the transmitting end and perform broadcast feedback, and simultaneously, the receiving end receives radio frequency energy through a special antenna and converts the radio frequency energy into electric energy for working and storage.
Therefore, the invention solves the energy supply problem of the low-power iot equipment, and dynamically adjusts the direction and the power through the self-adaptive technology, so that the terminal can obtain relatively enough energy through radio frequency energy to support the equipment to work.
Referring to fig. 5, the radio frequency charging method according to the embodiment of the present invention includes the following steps:
and S100, detecting the current signal intensity of the charging receiving end by the transmitting end main control circuit through the rotatable radio frequency charging antenna.
In one implementation, the step S100 specifically includes: the transmitting terminal main control circuit starts signal broadcasting with fixed power through the rotatable radio frequency charging antenna, and monitors signal feedback of the charging receiving terminal to obtain current signal strength.
Specifically, in this embodiment, the signal strength of the charging receiving terminal is obtained through the charging transmitting terminal, the approximate position of the charging receiving terminal can be known, and if the current connection signal is weak, the rotatable radio frequency charging antenna can be pointed to the position of the charging receiving terminal, so that the distance between the charging transmitting terminal and the charging receiving terminal is shortened, and the charging receiving terminal is ensured to be located in a more efficient signal coverage range of the directional gain antenna. In addition, if the signal feedback of the charging receiving end is not monitored, the charging receiving end is not in the coverage range of the charging signal, and at the moment, the rotatable radio frequency charging antenna is driven to rotate to search the charging receiving end, so that the applicability of the system is further improved.
In one implementation, the radio frequency charging method further includes: when the transmitting terminal communication antenna searches for the radio frequency signal sent by the communication equipment, the transmitting terminal main control circuit establishes connection with the communication equipment and starts signal relay.
Specifically, the radio frequency charging device can search for a radio frequency signal of the communication equipment, for example, a WiFi signal of a WiFi router, and judge whether the WiFi signal is searched, if so, establish communication connection with the WiFi router, and start signal relay, so that a function of expanding a WiFi signal range can be realized, and a user can also network while charging remotely, which is very convenient.
It can be understood that if the radio frequency charging device does not search for a WiFi signal, the radio frequency charging device may not connect to a communication device, directly detect the signal strength of the charging receiving end, determine the distance and the orientation of the charging receiving end, and adjust the angle and the transmitting power of the rotatable radio frequency charging antenna according to the distance and the orientation to implement the orientation function. That is, the rf charging device can charge the charging receiving terminal by itself.
The radio frequency charging method further comprises the following steps:
and S200, controlling the rotatable radio frequency charging antenna to rotate by the transmitting terminal main control circuit according to the current signal strength.
In one implementation, the step S200 specifically includes:
step S210, the transmitting terminal main control circuit compares the current signal strength with a preset strength value;
step S220, if the current signal strength is smaller than a preset strength value, controlling the rotatable rf charging antenna to rotate until the current signal strength reaches the preset strength value.
Specifically, the present embodiment sets a preset intensity value for determining the intensity of the signal. If the current signal strength is smaller than the preset strength value, the current signal strength is weaker, the radio frequency charging is not facilitated, and at the moment, the rotatable radio frequency charging antenna needs to be controlled to rotate until the current signal strength is stronger, so that the radio frequency charging efficiency is improved.
The radio frequency charging method further comprises the following steps:
step S300, when the current signal strength reaches a preset strength value, the rotatable radio frequency charging antenna stops rotating, the transmitting power is increased to the preset power, and radio frequency charging energy is transmitted to the charging receiving end according to the preset power.
Specifically, when the current signal strength reaches the preset strength value, it is indicated that the signal strength at this time is strong, and the signal power can be maintained, so that the rotatable radio frequency charging antenna does not rotate any more, the transmission power is increased to the preset power at this position, and the radio frequency charging energy is transmitted to the charging receiving end according to the preset power. The preset power may be a maximum power, i.e., a safety limit power.
In one embodiment, the step S200 is followed by: and if the current signal strength cannot reach the preset strength value, driving the rotatable radio frequency charging antenna to rotate to the position with the maximum signal strength, and transmitting radio frequency charging energy to the charging receiving end according to preset power.
Specifically, when the receiving end that charges is relatively far away from the transmitting end that charges, can appear no matter how rotatory rotatable radio frequency charging antenna appears, current signal strength can not reach and predetermine the intensity value. At this time, the rotatable RF charging antenna is driven to rotate to the direction with the maximum signal intensity. Meanwhile, the antenna adjusting circuit increases the transmitting power (within a safe power range), enhances the charging signal and further realizes stronger charging of the charging signal.
When the position of the terminal device of the charging receiving end is adjusted, as shown in fig. 3 and 4, the charging transmitting end automatically detects and adjusts the angle and the transmitting power of the rotatable rf charging antenna, so that the terminal device of the charging receiving end is always in the coverage of the charging signal and a certain signal strength is ensured to maintain the charging power.
That is, when the charging receiving end moves, the above steps are repeated to adjust the antenna direction and power, so as to achieve the optimal charging transmitting angle and transmitting power, and realize automatic tracking.
