Description

Technical Field

[0001] The present invention relates to a multi-scenario charging system and method, and belongs to the technical field of wireless charging. Background Art

[0002] Compared to traditional wired energy transmission methods, wireless energy transmission technology enables contactless energy transfer, significantly increasing the convenience of charging devices. This makes it especially possible to charge devices such as electric vehicles while on the move. Commonly used wireless energy transmission technologies include electromagnetic induction, magnetic resonance, and electric field coupling. Electromagnetic induction typically has a transmission distance of a few millimeters to a few centimeters, offering high energy conversion efficiency but requiring device alignment. Magnetic resonance allows charging at greater distances, with transmission distances ranging from a few centimeters to several meters. Electric field coupling transmission is suitable for specific applications, but has limited effectiveness and transmission distance, typically used for devices requiring close-range charging. In recent years, microwave wireless energy transmission has been increasingly adopted for wireless charging. While this technology offers significant advantages in terms of coverage and transmission distance, the omnidirectional nature of microwave radiation presents significant challenges in ensuring safe transmission without endangering life, transmission strength, and transmission efficiency.

[0003] Microwave directional energy transmission technology can transmit microwave energy to the energy receiving device in a predetermined direction, with the characteristics of high efficiency and speed. The key to realizing wireless energy transmission with this technology lies in adapting to existing infrastructure without large-scale changes to existing transportation systems or modes, the energy transmission system quickly tracking and locking the energy receiving system (fixedly installed on the energy receiving device that needs wireless charging) in a one-to-many manner to provide continuous wireless energy, the energy transmission process reducing electromagnetic pollution and damage to life, and the rapid billing and settlement of the transmitted electricity. This can achieve rapid and large-scale energy replenishment for stationary or mobile energy receiving devices, solving the problem of power anxiety in electric drive equipment, especially the range anxiety of electric vehicles.

[0031] The multi-scenario charging method based on microwave wireless directional energy transfer technology described in the present invention includes the following steps:

[0032] Step 1: The energy transmission system sends a weak microwave broadcast energy signal to the area it covers;

[0033] Step 2: The energy receiving system enters the wireless charging area, and the microwave broadcast energy signal of the energy transmitting system covers it;

[0034] Step 3. After the receiving system enters the wireless charging area, select manual mode charging or automatic mode charging;

[0035] Step 4: If the manual mode or the automatic mode allows the energy receiving system to receive microwave energy for charging, then proceed to step 6; if the manual mode or the automatic mode does not allow the energy receiving system to receive microwave energy, then proceed to step 5;

[0036] Step 5: If charging is not performed in manual or automatic mode, the wireless charging request is ignored and the energy receiving system does not operate.

[0037] Step 6: Whether the energy receiving array device in the energy receiving subsystem can actively track and adjust the direction;

[0038] Step 7: The energy transmission system activates its internal corresponding energy transmission array according to the received guide wave signal and identity information of the energy receiving system, and transmits microwave energy waves of specified intensity along the reverse trajectory of the guide wave, thereby starting high-intensity transmission of microwave energy;

[0039] Step 8: During the energy transmission process of the energy transmission system, the safety monitoring module will send information on whether the energy transmission is safe to the energy receiving unit to determine whether the energy transmission process continues;

[0040] Step 9: If the safety monitoring module monitors that the energy transmission process is safe, then go to step 12; if the safety monitoring module monitors that the energy transmission process is unsafe, then go to step 10 and continue to step 11;

[0041] Step 10: If the energy transmission process is cut off manually or automatically, or if the safety monitoring module detects that energy transmission is not suitable for further use, the process enters the energy cost settlement unit;

[0042] Step 11: The entire energy transfer process ends;

[0043] Step 12: The speed measuring unit within the energy transmission system constantly monitors the speed of the energy receiving system that is receiving energy and predicts its position information at the next moment. Based on the predicted position information of the energy receiving system, the energy transmission system promptly switches the energy transmission array within the energy transmission system corresponding to the next position of the energy receiving system and continues to transmit microwave energy waves, ensuring that the energy receiving system in motion receives energy continuously.

[0044] Step 13: The energy receiving system detects the charging status of the energy receiving device and determines whether it is fully charged or has reached the set energy receiving value;

[0045] Step 14: If the energy received by the energy receiving device has reached the predetermined value or is fully charged, then proceed to step 15 for settlement; if the energy received by the energy receiving device has not reached the predetermined value or is not fully charged, then proceed to step 12 for energy transmission;

[0046] Step 15: Start the settlement of energy received by the energy receiving system. After the settlement is completed, the entire energy transmission process ends.

[0047] Furthermore, the manual mode charging process in step 3 is as follows:

[0048] The area where the energy transmission system is located is clearly marked. The actual controller of the energy receiving device where the energy receiving system is located sees the wireless charging area sign and knows that wireless charging is available in this area.

[0049] The actual controller of the energy receiving device controls the energy receiving system through mechanical, touch, and voice control according to the actual energy charging status of the electric drive device;

[0050] The charging process in automatic mode is as follows:

[0051] The weak microwave energy receiving unit of the energy receiving system senses that the device has entered the wireless charging area and issues a reminder or request for wireless charging.

[0052] The actual controller of the energy receiving device where the energy receiving system is located can respond through mechanical, touch, and voice control operations.

[0053] Furthermore, in step 6, the microwave wireless energy transmission process includes a fixed energy receiving system mode and a movable energy receiving system mode;

[0054] The steps of the fixed energy receiving system model include:

[0055] Step 601: The wave signal generators in the modular energy receiving units in different divided areas transmit guided wave signals in a predetermined direction;

[0056] Step 602: The corresponding module of the energy transmission system receives the guide wave signal containing identity information from multiple energy receiving units of the energy receiving system;

[0057] Step 603: The microwave transmitting array device of the energy transmission system transmits a microwave energy wave of a specified standard intensity along the reverse path of the guided wave using an inverse beam management technology.

[0058] Step 604: Different subsystems in the energy receiving system receive the microwave energy waves transmitted by the energy transmitting system and transmit the intensity values ​​to the energy receiving subsystem control module or further to the energy receiving system master control subsystem;

[0059] Step 605: The energy receiving subsystem control module analyzes the microwave energy intensities received by different energy receiving arrays within it. If the microwave energy intensities received by some energy receiving arrays are less than a threshold value A1, these energy receiving arrays will not participate in this energy receiving. Only the energy receiving arrays that receive microwave energy intensities greater than the threshold value A1 will participate in this wireless energy transmission.

[0060] Step 606: The energy receiving system master control subsystem or the energy receiving subsystem control module provides the identity information of the energy receiving devices participating in the energy receiving, and transmits the information to the energy transmission system via wireless communication. The system also transmits the corresponding guide wave signal of the energy receiving system, and the subsequent operation proceeds to step 7.

[0061] The steps of the movable energy receiving system model include:

[0062] Step 601: The energy receiving array of the energy receiving subsystem and its wave signal generator perform a mechanical or electronic two-dimensional scan within a certain angle range. During this scanning process, the wave signal generator continuously emits a guide wave signal, the intensity of which will not cause harm to living organisms or important targets.

[0063] Step 602: The corresponding module in the energy transmission system receives the guide wave signal containing the identity information from the energy receiving system and analyzes the source direction of the guide wave;

[0064] Step 603: After analyzing and obtaining necessary information such as the direction of the guided wave signal sent by the energy receiving system, the energy transmission system master control subsystem or the energy transmission subsystem control module transmits a microwave energy wave of a specified standard intensity along the reverse path of the guided wave using an inverse beam management technology;

[0065] Step 604: The energy receiving array of the energy receiving system receives the microwave energy wave transmitted by the energy transmission system and transmits the intensity and the angle value in the two-dimensional direction to the energy receiving system master control subsystem or the energy receiving subsystem control module;

[0066] Step 605: The energy receiving arrays in the energy receiving system analyze the received microwave energy intensity. If the microwave energy intensity received by some energy receiving units is less than a threshold value A1, these energy receiving arrays will not participate in energy reception. Energy receiving arrays with an intensity greater than the threshold value A1 will participate in energy transmission.

[0067] Step 606: The energy receiving system determines the energy receiving array and its optimal energy receiving angle in two dimensions, and mechanically or electronically adjusts the energy receiving unit and its wave signal generator to the optimal position. This allows the energy transmission system to have a "point-to-point" directionality relative to the energy waves emitted by the energy receiving system, thereby achieving the highest efficiency in energy output and reception.

[0068] Step 607: The energy receiving system provides the identity information of the energy receiving devices participating in the energy receiving and sends it to the energy transmission system via wireless communication. At the same time, it transmits the guide wave signal corresponding to the energy receiving system installed in these energy receiving devices. The subsequent operation goes to step 7.

[0069] The beneficial effects of the present invention are:

[0070] 1. The present invention adopts directional microwave energy transmission. The microwave energy emitted by the energy transmission system can be received by the energy receiving system in a directional and aligned manner, thus realizing long-distance energy transmission;

[0071] 2. The present invention is based on a directional microwave energy transmission mode, which realizes one-to-one reception of transmitted energy and received energy. The received energy density is high, which can realize high-efficiency transmission and reception of wireless microwave energy.

[0072] 3. The energy transmission system of the present invention can measure the speed, track and lock the energy receiving equipment, and on this basis, realize the connection of energy transmission through different energy transmission systems, which is particularly suitable for energy transmission to mobile devices;

[0073] 4. The energy receiving array in the energy receiving system is equipped with microwave blocking materials, and the energy transmission process has a safety monitoring module to ensure that organisms and important targets are not harmed by strong microwave energy during the energy transmission process, making wireless microwave energy transmission highly safe. At the same time, when there is no energy receiving system that needs to be wirelessly charged in the area covered by the energy transmission system, the energy transmission system can not emit or emit very low-intensity microwave energy, which is almost harmless to organisms.

[0074] 5. The energy transmission subsystem and energy receiving subsystem of the present invention can be modularized and combined for use, and can be flexibly configured according to actual use requirements;

[0075] 6. The present invention can monitor and record the energy obtained by the energy receiving system in real time through the billing module and make real-time settlement according to the established settlement rules, making the present invention highly commercially feasible;

[0076] 7. The present invention is suitable for a variety of application scenarios, meeting both fixed and mobile charging needs, covering all scenarios of electric drive equipment and industrial and mining charging needs;

[0077] 8. The application scenarios provided by the present invention will not damage existing facilities. For example, if the road surface is excavated to deploy the energy transmission system of the present invention, it can be installed on the sides of the existing road surface, on the roof of the garage, or in fixed facilities in homes or factories. It can also be expanded and installed in existing highway service areas. It has strong compatibility with existing facilities and can be easily and quickly promoted.

[0078] 9. The present invention mainly involves the research and development of energy transmission systems and energy receiving systems. Both can be directly installed on existing facilities or existing electric drive equipment, and have the characteristics of low modification and use costs.

[0079] 10. When a certain energy transmission system or energy receiving system fails, the failed energy transmission system or energy receiving system can be directly replaced, which has the characteristics of simple and fast maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0126] Specific implementation method 2: Figure 10 As shown, a multi-scenario charging method based on microwave wireless directional energy transfer technology includes the following steps:

[0127] Step 1: The energy transmission system sends a weak microwave broadcast energy signal to the area it covers;

[0128] Step 2: The energy receiving system enters the wireless charging area, and the microwave broadcast energy signal of the energy transmitting system covers it;

[0129] Step 3. After the receiving system enters the wireless charging area, select manual mode charging or automatic mode charging;

[0130] The process of manual mode charging is as follows:

[0131] The area where the energy transmission system is located is clearly marked. The actual controller of the energy receiving device where the energy receiving system is located sees the wireless charging area sign and knows that wireless charging is available in this area.

[0136] Step 4: If the manual mode or the automatic mode allows the energy receiving system to receive microwave energy for charging, then proceed to step 6; if the manual mode or the automatic mode does not allow the energy receiving system to receive microwave energy, then proceed to step 5;

[0137] Step 5: If charging is not performed in manual or automatic mode, the wireless charging request is ignored and the energy receiving system does not operate.

[0138] Step 6: Whether the energy receiving array device in the energy receiving subsystem can actively track and adjust the direction;

[0139] The microwave wireless energy transmission process includes a fixed energy receiving system mode and a movable energy receiving system mode;

[0140] The steps of the fixed energy receiving system model include:

[0141] Step 601: The wave signal generators in the modular energy receiving units in different divided areas transmit guided wave signals in a predetermined direction;

[0142] Step 602: The corresponding module of the energy transmission system receives the guide wave signal containing identity information from multiple energy receiving units of the energy receiving system;

[0143] Step 603: The microwave transmitting array device of the energy transmission system transmits a microwave energy wave of a specified standard intensity along the reverse path of the guided wave using an inverse beam management technology.

[0144] Step 604: Different subsystems in the energy receiving system receive the microwave energy waves transmitted by the energy transmitting system and transmit the intensity values ​​to the energy receiving subsystem control module or further to the energy receiving system master control subsystem;

[0145] Step 605: The energy receiving subsystem control module analyzes the microwave energy intensities received by different energy receiving arrays within it. If the microwave energy intensities received by some energy receiving arrays are less than a threshold value A1, these energy receiving arrays will not participate in this energy receiving. Only the energy receiving arrays that receive microwave energy intensities greater than the threshold value A1 will participate in this wireless energy transmission.

[0146] Step 606: The energy receiving system master control subsystem or the energy receiving subsystem control module provides the identity information of the energy receiving devices participating in the energy receiving, and transmits the information to the energy transmission system via wireless communication.

[0149] Step 602: The corresponding module in the energy transmission system receives the guide wave signal containing the identity information from the energy receiving system and analyzes the source direction of the guide wave;

[0150] Step 603: After analyzing and obtaining necessary information such as the direction of the guided wave signal sent by the energy receiving system, the energy transmission system master control subsystem or the energy transmission subsystem control module transmits a microwave energy wave of a specified standard intensity along the reverse path of the guided wave using an inverse beam management technology;

[0151] Step 604: The energy receiving array of the energy receiving system receives the microwave energy wave transmitted by the energy transmission system and transmits the intensity and the angle value in the two-dimensional direction to the energy receiving system master control subsystem or the energy receiving subsystem control module;

[0152] Step 605: The energy receiving arrays in the energy receiving system analyze the received microwave energy intensity.

[0158] Step 10: If the energy transmission process is cut off manually or automatically, or if the safety monitoring module detects that energy transmission is not suitable for further use, the process enters the energy cost settlement unit;

[0159] Step 11: The entire energy transfer process ends;

[0160] Step 12: The speed measuring unit within the energy transmission system constantly monitors the speed of the energy receiving system that is receiving energy and predicts its position information at the next moment. Based on the predicted position information of the energy receiving system, the energy transmission system promptly switches the energy transmission array within the energy transmission system corresponding to the next position of the energy receiving system and continues to transmit microwave energy waves, ensuring that the energy receiving system in motion receives energy continuously.

[0161] Step 13: The energy receiving system detects the charging status of the energy receiving device and determines whether it is fully charged or has reached the set energy receiving value;

[0162] Step 14: If the energy received by the energy receiving device has reached the predetermined value or is fully charged, then proceed to step 15 for settlement; if the energy received by the energy receiving device has not reached the predetermined value or is not fully charged, then proceed to step 12 for energy transmission;

[0163] Step 15: Start the settlement of energy received by the energy receiving system. After the settlement is completed, the entire energy transmission process ends.

[0165] like Figure 1 As shown, the energy receiving system includes n energy receiving subsystems and 1 energy receiving master control subsystem. At the same time, each energy receiving subsystem includes multiple modules, units or devices to realize its basic functions and performances.

[0166] If the energy receiving device is small or requires a small amount of charging, only a single energy receiving subsystem can be selected to complete the wireless energy reception;

[0167] If the energy receiving device is large in size or requires a large amount of charging, ≥2 energy receiving subsystems can be selected. At this time, it is necessary to select an energy receiving master control subsystem at the same time. The master control subsystem is used to manage and coordinate ≥2 energy receiving subsystems.

[0168] like Figure 2 As shown, the energy transmission system includes n energy transmission subsystems and 1 energy transmission master control subsystem. At the same time, each energy transmission subsystem includes multiple modules, units or devices to realize its basic functions and performance;

[0169] If the energy transmission system does not need to provide a large amount of wireless energy, the energy transmission system may only include a single energy transmission subsystem;

[0170] If the energy transmission system needs to provide a large amount of wireless energy, the energy transmission system can include ≥2 energy transmission subsystems. At this time, it is necessary to select an energy transmission master control subsystem at the same time. The master control subsystem is used to manage and coordinate ≥2 energy transmission subsystems.

[0171] like Figure 3As shown, the energy receiving subsystem includes an energy receiving array, a guided wave signal generator, a wireless communication module, an energy wave intensity monitoring module, a billing module, a control module, an electronic and / or mechanical energy receiving array two-dimensional adjustment device, and a safety detection module;

[0172] The electronic and / or mechanical energy receiving array two-dimensional adjustment device needs to be added or removed according to actual usage. The energy receiving equipment may also include other numbers or types of related functional modules or functional units;

[0173] The energy receiving array receives the wireless microwave energy emitted by the energy transmission system through a large number of distributed array microwave energy receiving devices or units; the guide wave signal generator sends energy wave guidance signals for directional energy transmission to the energy transmission system. Through the inverse beam management technology and the electronic and / or mechanical adjustment of the energy receiving array and / or the energy wave transmitting array, the microwaves of the energy transmission system can be directionally focused on the energy receiving array to achieve high-intensity, high-efficiency and high-speed power transmission; the wireless communication module realizes the transmission of various instructions and information sharing between the energy receiving system and the energy transmission system, and between the energy receiving system and other related equipment; the energy wave intensity monitoring module is used to monitor the changes in microwave energy intensity during the stable energy transmission process of the energy transmission system to the energy receiving system, so as to achieve high-intensity, high-efficiency and high-speed power transmission. To achieve safe transmission of microwave energy and avoid damage to living organisms or other important objects; a billing module is used to record the energy transmitted from the energy transmission system to the energy receiving system during the entire energy transmission process, thereby realizing the monetization of energy and deducting the corresponding amount from the account of the actual controller of the energy receiving device; a control module is responsible for the coordination of actions of other modules or units of the energy receiving subsystem, signal analysis and processing, command transmission, energy management, etc.; an electronic and / or mechanical two-dimensional adjustment device for the energy receiving array is used to adjust the alignment direction of the energy receiving array according to the microwave signal emitted by the energy transmission subsystem array to achieve efficient microwave energy reception. Adjustment can be achieved electronically, mechanically, or a combination of both. If the energy receiving array is fixedly installed, this device is not required and can be installed selectively according to actual needs; a safety detection module detects the safety of the energy transmission process based on the information from the energy wave intensity monitoring module. If the transmission process is determined to be unsafe, it coordinates the control module of the energy receiving system or subsystem and the energy transmission system to cut off the transmitted energy wave.

[0174] like Figure 4 As shown, the energy transmission subsystem includes an energy wave transmitting array, a guide wave signal receiving module, a control module, a wireless communication module, an electronic and / or mechanical transmitting array two-dimensional adjustment device, and a speed measurement and tracking locking module;

[0175] Electronic and / or mechanical powered array two-dimensional adjustment devices need to be added or removed according to actual usage;

[0176] The energy transmission subsystem may also include other numbers or types of related functional modules or functional units;

[0177] The energy wave transmitting array is used to transmit microwave energy signals to the receiving system to achieve energy transmission. The number of energy wave transmitting arrays is determined based on actual needs. When not transmitting energy, they only emit very weak broadcast signals, minimizing radiation damage to organisms or important objects. Only after receiving the energy transmission request signal from the receiving system and establishing contact will they output high-intensity microwave signals in a targeted manner. The guided wave signal receiving module is used to receive the guided waves emitted by the receiving system and, through inverse beam management technology, enables the energy wave transmitting array to accurately transmit microwave energy to the receiving array. The control module coordinates the coordinated operation of the modules and units of the energy transmission system or subsystem, performs signal analysis and processing, sends commands, and manages energy. The wireless communication module facilitates the transmission of various commands and information sharing between the energy transmission system and the receiving system, and between the energy transmission system and other related equipment. The electronic and / or mechanical two-dimensional adjustment device for the transmitting array adjusts the alignment of the transmitting array of the energy transmission system based on the guided wave signals emitted by the receiving system's receiving array to achieve efficient microwave energy transmission. This adjustment can be achieved electronically, mechanically, or a combination of both. If the energy transmission system's transmitting array is fixed, this device is optional and can be installed selectively based on actual needs. The speed measurement and tracking and locking module is primarily used to meet the energy transmission needs of mobile devices. When the energy transmission system has multiple energy wave transmitting arrays, this module can measure the speed of the corresponding energy receiving device's energy receiving system and predict its position at the next moment. It can also track and lock its position, promptly switching to the energy wave transmitting array corresponding to the next position to transmit energy to it. This module can achieve energy transmission from a single energy transmission system to multiple energy receiving devices.

[0178] like Figure 5 As shown, the energy receiving array consists of an energy receiving array device, a microwave blocking material, and a wave-transparent material. The energy receiving array device is mounted on a substrate formed by the microwave blocking material. The wave-transparent material does not affect the input of microwaves and forms a sealed protection for the energy receiving array device, thereby preventing the energy receiving array from being damaged or foreign objects and dust from entering. The microwave blocking material has a blocking or shielding effect on the input microwaves, preventing them from passing through, thereby protecting important targets or organisms behind the microwave blocking material from microwave damage. The microwave blocking material can be aluminum foil or other materials with similar properties. The wave-transparent material can be installed or not installed according to actual needs. The energy receiving array can be used independently or as a basic module, which can be used in combination with a large number of such modules.

[0179] like Figure 6As shown, the energy transmission array is mainly composed of microwave emitting array devices, microwave blocking materials, and wave-transparent materials. The microwave emitting array devices are installed on a substrate formed by the microwave blocking material. The wave-transparent material does not affect the output of microwaves and forms a closed protection for the microwave emitting array devices, thereby preventing damage to the energy receiving array or the entry of foreign objects and dust. The microwave blocking material has a blocking or shielding effect on the input microwaves, preventing them from penetrating, thereby protecting important targets or organisms behind the microwave blocking material from microwave damage. The microwave blocking material can be aluminum foil or other materials with similar properties. The wave-transparent material and microwave blocking material can be installed or not installed according to actual needs. The energy transmission array can be used independently or as a basic module, which can be used in combination with a large number of such modules.

[0180] like Figure 7 As shown in the figure, there are multiple feasible curved surfaces or surface combination structures of the energy receiving array in the energy receiving system or subsystem, and the layout of the energy receiving array device or microwave transmitting array device has not only Figure 5 and Figure 6 The plane layout can also be arranged in a variety of ways according to actual needs, such as spatial curved surface layout, spherical layout, hemispherical layout, multi-plane combination layout, plane and curved surface combination layout, etc.

[0181] like Figure 8 As shown, the energy receiving array or microwave transmitting array is divided into nine areas I to IX, each area contains a different number of array devices, such as Figure 8 (a) As shown. Taking areas VII, VIII and IX as examples, their A-direction views are as follows: Figure 8 (b)~ Figure 8 (e)

[0182] Figure 8 (b)~ Figure 8 (e) It can be understood that the array device is fixedly installed and cannot move or rotate during actual operation. That is, when the array device is installed, its direction is fixed;

[0183] Figure 8 (b)~ Figure 8 (e) It can be understood that the array device is fixedly installed and cannot move or rotate during actual operation. That is, when the array device is installed, its direction is fixed;

[0184] If the array device is not fixedly installed, that is, it can track autonomously according to the intensity of microwave energy, then the array device can be quickly adjusted in direction under the action of a mechanical two-dimensional adjustment device, such as Figure 8 (c) Figure 8 (d) or Figure 8 (e) as shown; it can also be Figure 8(a) Based on the structure, the transmission or reception direction is adjusted by electronically adjusting the phase.

[0185] like Figure 9 As shown, Figure 9 As shown in (a), for electric vehicles, the energy receiving system can be installed on the roof, hood, left and right doors, rear compartment, and chassis. In combination with the energy transmission mode of the present invention, it is generally more appropriate to install the energy receiving system on the roof and hood. The microwave blocking material in the energy receiving array can ensure that the passengers in the car or important components in the car are protected from damage by microwaves. Figure 9 As shown in (b), for smart home devices such as sweeping robots, it is more appropriate to install the energy receiving system on the top cover, such as Figure 9 As shown in (c), taking a mobile phone as a typical example of a portable electronic device, it is more appropriate to install the energy receiving system on its back side (non-working side).

[0186] like Figure 10 As shown, a method for wireless power transmission from an energy transmission system to an energy receiving system includes the following steps:

[0187] S1001: The energy transmission system transmits a weak microwave broadcast energy signal to the area it covers. The broadcast energy signal is only transmitted intermittently to the area it covers. The transmitted microwave energy is relatively weak and will not cause harm to living organisms or important targets.

[0188] Among them, the energy transmission system can be turned on or off by manually broadcasting energy signals;

[0189] The energy transmission system can detect traffic or other targets that need to be charged through monitoring means such as images and radar. When the target enters the covered area, the broadcast signal is automatically turned on. When the target is detected in the covered area, the broadcast signal is automatically turned off.

[0190] S1002: The energy receiving system enters the wireless charging area and is covered by the microwave broadcast energy signal of the energy transmitting system;

[0191] S1003: After the energy receiving system enters the wireless charging area, whether it needs to be wirelessly charged has two operation steps, namely S100301 manual mode and S100302 automatic mode;

[0192] S100301 Manual Mode:

[0193] S100301-01: The area where the energy transmission system is located is clearly marked. The actual controller of the energy receiving device where the energy receiving system is located sees the wireless charging area sign and understands that wireless charging is available in this area.

[0194] S100301-02: The actual controller of the energy receiving device controls the energy receiving system by mechanical, touch, voice control, etc. according to the actual energy charging status of the electric drive device. The control result is shown in step S1004;

[0195] S100302 Automatic mode:

[0196] S100302-01, the weak microwave energy receiving unit of the energy receiving system senses entry into the wireless charging area and issues a reminder or request for wireless charging;

[0197] S100302-02, the actual controller of the energy receiving device where the energy receiving system is located can respond through mechanical, touch, voice control and other operations. The control result is shown in step S1004;

[0198] S1004, if the manual mode or the automatic mode allows the energy receiving system to receive microwave energy for charging, then proceed to step S1006; if the manual mode or the automatic mode does not allow the energy receiving system to receive microwave energy, then proceed to step S1005;

[0199] S1005: If charging is not performed in manual or automatic mode, the wireless charging request is ignored and the energy receiving system does not operate.

[0200] S1006, depending on whether the energy receiving array device in the energy receiving subsystem can actively track and adjust the direction, there are two operation steps in the microwave wireless energy transmission process, namely S100601 fixed energy receiving system mode and S100602 movable energy receiving system mode;

[0201] S100601 Fixed energy receiving system mode:

[0202] S100601-01, the wave signal generators in the modular energy receiving units in different divided areas transmit guided wave signals in a predetermined direction. This signal is a broadcast type signal with a relatively weak signal strength and is not harmful.

[0203] S100601-02: The corresponding module of the energy transmission system receives the guide wave signal containing identity information from multiple energy receiving units of the energy receiving system;

[0204] S100601-03, the microwave transmitting array device of the energy transmission system transmits the specified standard intensity microwave energy wave along the reverse path of the guided wave through the reverse beam management technology;

[0205] S100601-04, different subsystems in the energy receiving system receive the microwave energy waves transmitted by the energy transmitting system and transmit the intensity values ​​to the control module of the energy receiving subsystem or further to the master control subsystem of the energy receiving system;

[0206] S100601-05: The energy receiving subsystem control module analyzes the microwave energy intensity received by different energy receiving arrays within it. If the microwave energy intensity received by some energy receiving arrays is less than a threshold value A1, these energy receiving arrays will not participate in this energy receiving process. Only energy receiving arrays with microwave energy intensity greater than the threshold value A1 will participate in this wireless energy transmission process.

[0207] S100601-06: The energy receiving system master control subsystem or the energy receiving subsystem control module provides the identity information of the energy receiving device participating in the energy receiving, and transmits it to the energy transmission system via wireless communication. The system also transmits the corresponding guide wave signal of the energy receiving system, and the subsequent operation proceeds to step S1007.

[0208] S100602 movable energy receiving system mode:

[0209] S100602-01, the energy receiving subsystem's energy receiving array and its wave signal generator perform mechanical or electronic two-dimensional scanning within a certain angle range. During this scanning process, the wave signal generator continuously emits a guide wave signal, the intensity of which will not cause harm to living organisms or important targets;

[0210] S100602-02, the corresponding module in the energy transmission system receives the guide wave signal containing the identity information sent by the energy receiving system and analyzes the source direction of the guide wave;

[0211] S100602-03, after analyzing and obtaining necessary information such as the direction of the guided wave signal sent by the energy receiving system, the energy transmission system master control subsystem or the energy transmission subsystem control module transmits a microwave energy wave of specified standard intensity along the reverse path of the guided wave using the reverse beam management technology;

[0212] S100602-04, the energy receiving array of the energy receiving system receives the microwave energy wave transmitted by the energy transmission system and transmits the intensity and the angle value in the two-dimensional direction to the energy receiving system master control subsystem or the energy receiving subsystem control module;

[0213] S100602-05: The energy receiving arrays in the energy receiving system analyze the received microwave energy intensity. If the microwave energy intensity received by some energy receiving units is less than a threshold value A1, these energy receiving arrays will not participate in energy reception. Energy receiving arrays with an intensity greater than the threshold value A1 will participate in energy transmission.

[0214] S100602-06, the energy receiving system determines the energy receiving array and its optimal energy receiving angle in two dimensions and mechanically or electronically adjusts the energy receiving unit and its wave signal generator to the optimal position. This allows the energy transmission system to have a "point-to-point" directionality relative to the energy waves emitted by the energy receiving system, achieving the highest efficiency in energy output and reception.

[0215] S100602-07: The energy receiving system provides the identity information of the energy receiving devices participating in the energy receiving and sends it to the energy transmission system via wireless communication. At the same time, it transmits the guide wave signals corresponding to the energy receiving systems installed on these energy receiving devices. The subsequent operation then proceeds to step S1007.

[0216] S1007: The energy transmission system activates its internal corresponding energy transmission array based on the received guide wave signal and identity information of the energy receiving system to transmit microwave energy waves of a specified intensity along the reverse trajectory of the guide wave, thereby starting high-intensity transmission of microwave energy.

[0217] S1008, during the energy transmission process of the energy transmission system, the safety monitoring module sends information on whether the energy transmission is safe to the energy receiving unit, thereby determining whether the energy transmission process should continue. For details, please refer to the schematic flow chart of the microwave energy safety transmission method;

[0218] S1009: If the safety monitoring module monitors that the energy transmission process is safe, then the process proceeds to step S1012; if the safety monitoring module monitors that the energy transmission process is unsafe, then the process proceeds to step S1010 and then to step S1011. For details of step S1010, see the schematic flow chart of the wireless power transmission billing method.

[0219] S1010: If the energy transmission process is manually or automatically cut off, or if the safety monitoring module detects that energy transmission is no longer suitable, the process enters the energy cost settlement unit. For details, see the schematic flow chart of the wireless power transmission billing method.

[0220] S1011, the entire energy transfer process ends;

[0221] S1012: The speed measuring unit within the energy transmission system constantly monitors the speed of the energy receiving system currently receiving energy and predicts its position at the next moment. Based on the predicted position of the energy receiving system, the energy transmission system promptly switches the energy transmission array within the energy transmission system corresponding to the next position of the energy receiving system and continues to transmit microwave energy waves, ensuring continuous energy reception by the energy receiving system in motion. This method is particularly suitable for energy transmission to fast-moving devices such as electric vehicles, solving the problem of mobile charging.

[0222] S1013, the energy receiving system detects the charging status of the energy receiving device and determines whether it is fully charged or has reached the set energy receiving value;

[0223] S1014: If the energy received by the energy receiving device has reached the predetermined value or is fully charged, the process proceeds to step S1015 for settlement. If the energy received by the energy receiving device has not reached the predetermined value or is not fully charged, the process proceeds to step S1012 for energy transmission.

[0224] S1015, start the settlement of energy received by the energy receiving system. After the settlement is completed, the entire energy transmission process ends.

[0225] like Figure 11 As shown, Figure 11 (a) shows that when the mobile phone is receiving energy, the user suddenly reaches for the phone, which may endanger the user. Figure 11 (b) shows that when a smart home device is wirelessly charging and a pet suddenly runs onto the device, there is a risk of harm to the organism; Figure 9 (c) shows that when an electric vehicle is receiving wireless energy transmission, a pedestrian suddenly walks by the vehicle, or a person in the vehicle suddenly gets out, which may endanger human safety.

[0226] like Figure 12 As shown, a method for safe transmission of microwave energy includes the following steps:

[0227] S1201, before officially starting high-intensity energy transmission between the energy transmission system and the energy receiving system, the energy receiving system receives the microwave energy waves emitted by the energy transmission system and constantly monitors the intensity of the energy waves;

[0228] S1202: The energy transmission system starts transmitting microwave energy waves of a specified intensity to the energy receiving system, and the intensity of the energy waves received by the energy receiving system is not less than a specified threshold value A1;

[0229] S1203, during the energy transmission process, the energy receiving system detects abnormalities in the intensity of the received energy wave and quickly proceeds to step S1204;

[0230] S1204: If the safety detection module in the energy receiving system detects that the received energy intensity is less than a predetermined value A2, the process proceeds to step S1206; if the safety detection module in the energy receiving system detects that the received energy intensity is greater than the predetermined value A2, the process proceeds to step S1205, and the energy transmission process continues;

[0231] S1205 indicates that there are no living organisms or important targets between the energy transmission system and the energy receiving system, and there is no situation that will endanger the living organisms or important targets. The energy transmission process can be trained;

[0232] S1206, indicating that there is a living organism or important target between the energy transmission system and the energy receiving system, and there is a situation that endangers the living organism or important target, and the energy receiving system sends a termination signal to the energy transmission system;

[0233] S1207, upon receiving the energy transmission termination signal, the energy transmission system immediately cuts off the transmitted microwave energy and sends a cut-off success signal to the energy receiving system;

[0234] S1208, the energy receiving system issues an alarm after receiving the cut-off signal sent by the energy transmitting system, thereby notifying the actual operator of the energy receiving device that a dangerous situation that endangers living organisms or important targets has occurred and requires identification;

[0235] S1209: After receiving the alarm, the actual operator of the receiving device determines whether there are any living creatures or other obstructions in the transmission path through the naked eye, a camera, or other means, and makes a judgment;

[0236] S1210: If the controller of the receiving device determines that the energy transfer process can continue, the process proceeds to step S1211. If the controller of the receiving device determines that the energy transfer process cannot continue, the process proceeds to step S1212.

[0237] S1211: The controller of the energy receiving device starts the energy receiving system and sends a continue transmission signal to the energy transmitting system, and then proceeds to step S1205: the energy transmission process continues;

[0238] S1212, determining whether the energy receiving device has completed charging. If so, proceed to step S1213; if not, proceed to step S1210. If step S1210 is repeated three times and energy cannot be safely transmitted without completing charging, proceed directly to step S1213;

[0239] S1213: The entire wireless charging process ends.

[0240] like Figure 13 As shown, for electric vehicles, especially those used for mobile charging, where there are drivers or other passengers inside, if the energy receiving system of the present invention is installed on the roof, the microwave-blocking material provided therein can prevent microwaves from entering the vehicle. Other metal structures of the vehicle body can also prevent microwaves from entering the vehicle. However, considering factors such as microwave scattering, it is possible for microwaves to enter the vehicle through the vehicle windows. Therefore, the present invention replaces the existing vehicle windows with microwave-blocking glass (similar to the protective glass of microwave ovens), thus achieving comprehensive safety protection for vehicle occupants.

[0241] like Figure 14 As shown, a wireless power transmission billing method includes the following steps:

[0242] S1401, in order to realize the instant settlement of charging of the energy receiving device, a charging card or a built-in charging chip is inserted into the energy receiving device;

[0243] S1402, start the energy receiving device and enter the wireless charging area to start charging, and the billing card or billing chip starts to start;

[0244] S1403, the total power information received by the receiving device passes through the billing module of the receiving device;

[0245] S1404, before the receiving device is completely charged, the billing module is responsible for counting the power information continuously or intermittently obtained by the receiving device;

[0246] In step S1405, the charging module of the receiving device receives the charging end instruction, and then proceeds to step S1406, where the charging module starts to charge the total electric energy received.

[0247] S1406, the energy receiving equipment billing module converts the total electric energy obtained into a signal (including necessary information such as the identity of the energy receiving equipment) and sends it to the energy transmission system charging module via wireless communication;

[0248] S1407, the charging module of the energy transmission system deducts the corresponding fee from the account of the energy receiving device according to the established charging rules and sends the account balance and other information to the billing module of the energy receiving device via wireless communication;

[0249] S1408, the billing module of the energy receiving device sends a confirmation message to the charging module of the energy transmission system after receiving the confirmation message;

[0250] S1409: The charging module of the energy transmission system receives the information and proceeds to step S1410; otherwise, proceeds to step S1411;

[0251] S1410: The billing module works normally, the transaction is completed, and the corresponding fees are deducted normally;

[0252] S1411: According to the regulations, the signal is sent again until the upper limit of the specified number of transmissions is reached, and then the process goes to step S1212;

[0253] S1412: If the transaction is normal, proceed to step S1410 and the transaction ends; if it is still abnormal, proceed to step S1413;

[0254] S1413, transaction abnormality, transferred to manual processing.

[0255] like Figure 15 As shown, a wireless charging mode for electric vehicles traveling on highways is provided. A large number of energy transmission subsystems are erected on both sides of an appropriate section of the highway over a certain length and combined with an energy transmission system master control subsystem to form an energy transmission system. The energy transmission system can simultaneously lock and track multiple moving vehicles that need to be charged and can realize continuous energy transmission from the energy transmission unit to the locked vehicles according to the moving speed of the vehicles.

[0256] The energy waves emitted by each energy transmission subsystem can cover the road surface between it and the opposite energy transmission system;

[0257] Each energy transmission subsystem is located at a certain height, which can easily track and lock on moving vehicles.

[0258] like Figure 16As shown, a wireless mobile charging method for electric vehicles in highway service areas can be expanded and set up in any existing highway service area that provides fuel filling, such as Figure 16 As shown, two wireless charging zones for electric vehicles have been set up outside the existing service area, as shown in Area 1 and Area 2. Numerous wireless energy transmission systems have been erected on both sides of the roadside in Areas 1 and 2. The wireless energy transmission systems outside Areas 1 and 2 only have single-sided energy transmission capabilities, ensuring that electric vehicles traveling in those areas can receive wireless energy. Numerous double-sided wireless energy transmission systems are set up in the area where Areas 1 and 2 intersect. Together with the single-sided wireless energy transmission systems, they ensure comprehensive wireless energy coverage for electric vehicles traveling in Areas 1 and 2.

[0259] Electric vehicles that need to be charged enter from the entrance of area 1 or area 2. Their speed is controlled within a certain range and they can be fully charged when they reach the exit, and then directly enter the highway again.

[0260] Electric vehicles that need to be charged enter from the entrance of area 1 or area 2 and park next to or under the wireless energy transmission system. After charging is completed, they can directly leave the wireless charging area and go to the highway.

[0261] Shielding walls are set up in the wireless charging area and the rest and dining area, especially in the area between the fuel vehicles and the refueling area, to ensure that the microwave energy emitted by the wireless energy transmission system is blocked outside the rest and dining area / fuel vehicle refueling area.

[0262] like Figure 17 As shown, a wireless mobile charging method for electric vehicles at toll stations, Figure 13 The wireless energy transmission systems on both sides of the highway are arranged in the same manner. Generally speaking, vehicles are moving slower at toll booths, making it more convenient to wirelessly transmit and receive power.

[0263] like Figure 18 As shown, a wireless mobile charging method at traffic lights on urban roads, Figure 17 The layout and working method shown are similar, and it should also be understood that the number and layout of the wireless energy transmission systems in the lanes where the electric vehicles are located and on both sides of the road in this section are only an example and reference.

[0264] like Figure 19As shown, a wireless stationary charging method for electric vehicles in parking spaces or garages can be installed in underground garages and public parking lots. A wireless energy transmission system as shown in the figure can be installed above each vehicle roof, with an independently operating wireless energy transmission subsystem. When the vehicle is parked in the parking space, charging can be activated as needed, and automatically disconnected and settled after charging is completed. Because the electric vehicle and the wireless energy transmission subsystem are relatively aligned relative to each other in this operating condition, charging efficiency is relatively high and charging time is relatively short.

[0265] like Figure 20 As shown, a wireless static or mobile charging method for smart devices in homes or offices is provided. A smartphone can start wireless charging when needed, and automatically cut off energy reception after it is fully charged. A sweeping robot can be charged while moving, or it can stop at a predetermined location after work is completed and start wireless charging mode, and automatically cut off energy reception after it is fully charged.

[0266] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent replacement and improvement of the above embodiments made according to the technical essence of the present invention, within the spirit and principles of the present invention, without departing from the content of the technical solution of the present invention, shall still fall within the scope of protection of the technical solution of the present invention.

Step 604: Different subsystems in the energy receiving system receive the microwave energy waves transmitted by the energy transmitting system and transmit the intensity values ​​to the energy receiving subsystem control module or further to the energy receiving system master control subsystem; Step 605: The energy receiving subsystem control module analyzes the microwave energy intensities received by different energy receiving arrays within it. If the microwave energy intensities received by some energy receiving arrays are less than a threshold value A1, these energy receiving arrays will not participate in this energy receiving. Only the energy receiving arrays that receive microwave energy intensities greater than the threshold value A1 will participate in this wireless energy transmission. Step 606: The energy receiving system master control subsystem or the energy receiving subsystem control module provides the identity information of the energy receiving devices participating in the energy receiving, and transmits the information to the energy transmission system via wireless communication. The system also transmits the corresponding guide wave signal of the energy receiving system, and the subsequent operation proceeds to step 7. The steps of the movable energy receiving system model include: Step 601: The energy receiving array of the energy receiving subsystem and its wave signal generator perform a mechanical or electronic two-dimensional scan within a certain angle range. During this scanning process, the wave signal generator continuously emits a guide wave signal, the intensity of which will not cause harm to living organisms or important targets. Step 602: The corresponding module in the energy transmission system receives the guide wave signal containing the identity information from the energy receiving system and analyzes the source direction of the guide wave; Step 603: After analyzing and obtaining necessary information such as the direction of the guided wave signal sent by the energy receiving system, the energy transmission system master control subsystem or the energy transmission subsystem control module transmits a microwave energy wave of a specified standard intensity along the reverse path of the guided wave using an inverse beam management technology; Step 604: The energy receiving array of the energy receiving system receives the microwave energy wave transmitted by the energy transmission system and transmits the intensity and the angle value in the two-dimensional direction to the energy receiving system master control subsystem or the energy receiving subsystem control module; Step 605: The energy receiving arrays in the energy receiving system analyze the received microwave energy intensity. If the microwave energy intensity received by some energy receiving units is less than a threshold value A1, these energy receiving arrays will not participate in energy reception. Energy receiving arrays with an intensity greater than the threshold value A1 will participate in energy transmission. Step 606: The energy receiving system determines the energy receiving array and its optimal energy receiving angle in two dimensions, and mechanically or electronically adjusts the energy receiving unit and its wave signal generator to the optimal position. This allows the energy transmission system to have a "point-to-point" directionality relative to the energy waves emitted by the energy receiving system, thereby achieving the highest efficiency in energy output and reception. Step 607: The energy receiving system provides the identity information of the energy receiving devices participating in the energy receiving and sends it to the energy transmission system via wireless communication. At the same time, it transmits the guide wave signal corresponding to the energy receiving system installed in these energy receiving devices. The subsequent operation goes to step 7.
