Background Art

[0002] According to the latest technology, the supply of main energy, typically electricity, to household energy consumers such as electrical appliances requires the establishment of a metal contact between the main connection point and the electrical appliance. The most common way to do this is to connect the appliance to the main via an electrical cable. At the connection point, the connector at the end of the wire, typically a plug, needs to be connected to a socket that provides a connector, typically a metal contact, at the built-in main connection point. In Europe, the widely used standard CEE7 / 3 socket and CEE7 / 4 plug are used, and in the United States, Type A sockets and Type B plugs are used to connect electrical appliances to the main. Connection point To charge portable electrical devices, mainly, mobile phones and body-worn devices, low-power wireless chargers have been developed that enable (slow) charging of devices connected in the power range of 5 to 10 W. For example, such wireless chargers are provided by chargers and phones of the "Qi" standard. Those chargers can be placed on a support surface (e.g., a worktop) and can be semi-concealed, but they cannot move, and thus do not enable continuous (while moving) operation of typical portable household electrical appliances. Connection point To connect an electrical appliance to the main, Type A sockets and Type B plugs are used.

[0003]

[0004] ​For short-distance wireless transmission of electricity, two types of inductive coupling may be used: simple (standard) inductive coupling or resonant inductive coupling.

[0005] Generally, at relatively close distances, standard inductive coupling is less efficient and feasible because the magnetic flux is scattered away from the coil acting as the energy source, and only a small portion of the energy emitted by the transmitter is coupled to the receiver's coil.

[0006] Resonant inductive coupling operates with higher efficiency than standard inductive coupling, even over distances of a few meters (with a transmission efficiency of approximately 95%), and is efficient over relatively long distances. Therefore, by using resonant inductive coupling, energy loss can be significantly reduced, and electrical energy can be transmitted between individual coils with acceptable efficiency.

[0007] High-performance resonant energy transfer devices are currently used primarily for charging batteries in electric vehicles (e.g., passenger and truck vehicles, forklifts, work machines, etc.) as an easier alternative to metal contact charging. However, the drawbacks of this mode of energy transfer are that the vehicle cannot move during charging, the charger and vehicle must be precisely positioned relative to each other, and the vehicle cannot operate during charging.

[0008] [Patent Document 1] U.S. Patent Application Publication No. 2010 / 219183 [Overview of the project]

[0009] Therefore, while electrical devices are excited during operation and can move in the usual manner during energy consumption, there is a need for an energy supply system where energy intake is not static, thus enabling much greater mobility for the use of the device.

[0010] U.S. Patent Application Publication No. 2010 / 219183 describes a widely used power supply system. The system includes an inductive transmitter built behind a wall and an inductive receiver on the front side of the wall facing a living space. The receiver on the front side of the wall has a conventional (standard) socket that can be connected to a standard plug used in a given country. The receiver can move freely along the wall surface during use and can be detached from the wall when not in use. The transmitter behind the wall has a suitable positioning mechanism. The positioning mechanism includes a motor-driven carriage having a positioning tool that can move along a rail system. Identifying the carriage and positioning them appropriately relative to the receiver can be achieved in various ways, such as mechanically by infrared proximity sensors. The carriage on the back of the wall can be moved to the appropriate position in a motor-driven manner by moving an off-wall receiver or by using a control panel. A camera monitoring the space behind the wall may also be used to determine the position of the carriage carrying the transmitter (i.e., to track the carriage). The drawback of this solution is that, at best, the camera is used to track the movement of the carriage, meaning that the need to track the user's location via the camera and use that tracking information for control remains unresolved.

[0011] The objective of the present invention is to eliminate the problems mentioned above.

[0012] The objective is achieved by the system described in claim 1 and the method described in claim 6. Preferred embodiments of the system and method of the present invention are defined in the dependent claims.

[0013] The present invention will be described in further detail here with reference to the drawings. [Brief explanation of the drawing]

[0014] [Figure 1] This is a functional block diagram of the system according to the present invention. [Figure 2] A schematic example of the elements of the system according to the present invention, located on the front side of the support element, is shown. [Figure 3] A schematic example of the elements of the system according to the present invention, located on the rear side of the support element, is shown. [Figure 4] The main circuit elements in the transmitter and receiver used in the system according to the present invention, and their connections, are illustrated. [Figure 5] This flowchart illustrates the main steps for operating the system according to the present invention. [Modes for carrying out the invention]

[0015] As shown in Figures 1-3, according to the present invention, the system 100 comprises at least one planar support element 110 on a first side 112, i.e., on the rear side concealed from the user, on which the mechanical elements necessary for power supply are arranged, specifically comprising a transmitter 120 for wireless power transmission, a rail system 104 for moving the transmitter 120, a power transmission control unit 140 for controlling the power supply, and a motion control unit 150 for controlling the movement of the transmitter unit 120. On a second side 114 of the support element 110 opposite to the first side 112, i.e., on the side facing the room used by the user, a receiver 130 having an electrical socket 133 can be arranged to move along the surface of the support element 110. A particular support element 110 is typically provided with one transmitter 120, but a support element 110 with a larger surface area may have more than one transmitter 120, in which case each transmitter 120 has a predetermined and non-overlapping service area.

[0016] The rail system 104 includes a fixed first rail 105 extending in a first direction and typically running vertically, and a second rail 106 arranged typically horizontally in a second direction perpendicular to the first direction, the second rail 106 being connected to the first rail 105. The second rail 106 is provided with a motor 107, which enables the second rail 106 to move in the first direction relative to the first rail 105.

[0017] Each second rail 106 is connected to a resonant transmitter 120. Each transmitter 120 is provided with a motor 121, which allows the transmitter 120 to move in a second direction along the second rail 106 relative to each second rail 106. The transmitter 120 further includes a magnetic retainer 122, which can be magnetically attached to each magnetic retainer 132 of a receiver 130 located on the other side of the support element 110. During use, the transmitters 120 and receivers 130, located on opposite sides of the support element 110, are in close proximity to each other and are fixed relative to each other by the magnetic retainers 122 and 132, respectively, i.e., the receiver 130 moves with the transmitter 120 when the latter moves.

[0018] The transmitter unit 120 is powered by a power transmission control unit 140 connected to a power distribution network, which also monitors the operation of the transmitter 120. On the other hand, when the transmitter 120 is active, that is, when the receiver 130 is connected wirelessly and the transmitter 120 is continuously supplying power to its operating circuit, the power transmission control unit 140 provides the transmitter 120 with high-power electricity. The power transmission control unit 140 supplies electrical energy to the transmitter 120 via an electrical line, preferably a flexible swing line with appropriate mechanical protection and plastic cable guides.

[0019] The movement of the transmitter 120 is controlled by the movement control unit 150 by activating the motor 121 of the transmitter 120 and the motor 107 of the rail 106 respectively. The motors 107 and 121 are preferably bidirectional stepping motors, and the bidirectional stepping motors move the transmitter 120 or the movable rail 106 to the target position by rack and belt drive. The target position of the transmitter 120 is defined as the position where the receiver 130 having the electrical socket 133 moves based on the movement of the user operating the electrical appliance powered through the electrical socket 133. Both the X coordinate (second direction) and the vertical Y coordinate (first direction) control the motors 107 and 121 respectively, so that the transmitter 120 can move to any position substantially behind the entire surface of the support element 110. However, for technical reasons, it is advisable to leave a safety zone of a certain width (e.g., 20 centimeters) at the edge of the support element 110 where the transmitter 120 cannot enter. The movement control unit 150 is preferably connected to the motors 107 and 121 by swing lines, and the swing lines transmit both electrical energy and control signals.

[0020] The rail system 104 is preferably made of a metal alloy having wear resistance and high mechanical strength, and is mechanically attached to the support element 110, which can be a sufficiently solidified wall surface or a specially designed support structure, bracket, but can also be a vertical or horizontal part of furniture such as a table top, worktop, etc. Due to its flat design, the rail system 104 preferably protrudes only a few centimeters from the flat surface 114 on the rear side of the support element 110.

[0021] In a preferred embodiment of the system 100 according to the present invention, the transmitter 120 is in its idle state at a certain pre-set comfortable height according to the field of application. This idle position can be, for example, 30 centimeters above the floor level in the case of a self-standing installation, and the target position that can be occupied during use is restricted to values within a height range of, for example, 30 to 160 centimeters. In the case of a kitchen installation, the idle position can be, for example, at a height of 80 centimeters measured from the floor level, clearly taking into account the height that restricts the effect of the kitchen counter, and within a height range of 80 to 140 centimeters during use.

[0022] The movement control unit 150 that controls the movement of the transmitter 120 is preferably pre-programmed with the corresponding planar coordinates of the area that the transmitter 120 needs to avoid during its movement, since the receiver 130 is connected to it so as to follow its movement.

[0023] The transmitter 120 is connected by wire to the power distribution network at the installation side (e.g., home, office, etc.) via the power transmission control unit 140, and receives the electrical energy required for its own operation and for the operation of the electrical device 180 connected via the receiver 130 through this connection.

[0024] The main circuit elements of the resonant inductive coupling pair of the transmitter 120 and the receiver 130 used in the system of the present invention and their connections are illustrated in FIG. 4. The transmitter 120 includes a power supply unit 222 supplied from the power distribution network, and the power distribution network is connected to the resonator circuit 225 via a power amplifier 223 and an impedance matching circuit 224. The transmitter 120 also includes its own control circuit 226, and the control circuit 226 controls the operation of the power supply unit 222 and the power amplifier 223, and communicates with the receiver 130 via out-of-band signaling (e.g., at 2.4 gigahertz). The transmitter 120 is preferably connected to the main Connection pointIt connects to the network.

[0025] The receiver 130 receives energy provided by resonant inductive coupling via a resonator circuit 232 in a wireless manner. The energy is then transmitted as electrical energy to the electrical appliance 180 connected by the user via a control circuit 233 and a DC-DC converter circuit 234 that control the power delivered to the electrical appliance 180 by the transmitter 130. The operation of the aforementioned circuit unit is controlled by a dedicated control unit 235, which is also responsible for bidirectional communication with the transmitter 120. Control units 226 and 235 communicate wirelessly with each other, and thus the operation of the transmitter circuit is controlled according to the load.

[0026] The transmitter 120 preferably has a plastic case, which is advantageous in that it does not interfere with the emission of electromagnetic radiation. The 120 preferably has IP65, IP66, or IP67 mechanical protection, that is, it is fully protected against dust and protected against water jets or immersion for a limited time.

[0027] To minimize the depth required to mount the rail system 104 and the movable transmitter 120 when installed behind a support element 110 such as a wall structure or wall cladding, and to leave sufficient space behind the rail system 104 for the installation of other construction service equipment, the transmitter 120 is preferably designed to be flat.

[0028] The receiver 130, located on the front side 112 of the support element 110, includes the receiver-side circuitry mentioned earlier, a socket 133 for metal connection of the electrical appliance 180, and a magnetic fixing unit 132. The socket 133 is preferably a standard design socket, so that any conventional household electrical appliance can be connected to it.

[0029] The optimal operating frequency (i.e., the resonant frequency used) of the system 100 of the present invention primarily depends on the power scale of the electrical appliance 180 to be connected. For devices with several watts of power, the optimal operating frequency is approximately in the range of 1 to 5 megahertz for higher powers such as 200 to 1000 watts, while the power supply device can operate efficiently only in the range of several hundred kilohertz. The operation of the system 100 with optimal parameters is brought about by a PID controller implemented in the control circuit 233 of the receiver 130. To ensure accurate power transfer, the amplitude of the current in the primary coil in the receiver 120 can be varied by a PID controller having a resolution of several milliamperes.

[0030] The system of the present invention further includes a camera system 160, which includes at least two cameras 162 for tracking the movement of a user using an electrical appliance 180 in a space defined by a support element 110, such as a home or office room. Based on the images from the cameras 162, a central computer 170 connected thereto may determine the user's movement parameters, in particular the user's current spatial position, optionally also the user's current spatial velocity, and the spatial position of the excited electrical appliance 180 relative to the support element 110 which contains an active receiver 130 during use, for example, its height from the floor and its distance from the support element. Based on this information, it may instruct a motion control unit 150 to generate a motion control signal to move a receiver 120 on the rear side 114 of the support element 110 so that it is always close to the user and thereby always keeps the receiver 130 on the front side (user side) 112 of the support element in close proximity to the user.

[0031] The system 100 of the present invention preferably uses a color camera 162, which in a particularly preferred embodiment of the system 100 is mounted on the rear side 114 of the support member 110 in a concealed manner by having an optical sensor in the space defined by the front side 112 of the support member 110, such as a living room or a monitor office space. For this purpose, an opening 116 of appropriate size needs to be formed on the support element 110 and preferably concealed as much as possible. For example, if the support member 110 is formed as a wall structure composed of clad panels, the internal space in front of the wall structure can be detected through narrow bores formed between each panel, for example, 6 to 8 millimeters wide. The operation of the system 100 of the present invention can be brought to a particular room by the use of two appropriately positioned cameras 162 in one preferred embodiment of the system 100, but two or more of the support elements 110 that define a room used by a user include at least two cameras 162 preferably positioned on the left and right edges of a given support element 110, preferably at a height of 1 to 1.5 meters when two cameras are used. When more than two cameras are used per support element, the cameras 162 are evenly distributed. According to a particularly preferred embodiment of the system 100 according to the present invention, one or more support elements 110 may include two additional cameras on the lower and upper edges of the support element 110. The cameras 162 used in pairs (right and left, as well as bottom and top) allow the positions of users and objects (e.g., furniture, portable electrical appliances in use, etc.) in the room to be determined in three dimensions. If two or more support elements 110 include cameras 162, the camera system 160 has the ability to detect blind spots throughout the entire interior of the room, and thus track the movement of the portable electrical appliance 180 as accurately as possible, and to optimally move the receiver 130 accordingly. The identification, spatial positioning, and motion tracking of objects by two or more cameras are well known to those skilled in the art, and their technical details are not discussed herein.

[0032] In a preferred embodiment of the system according to the present invention, the central computer 170 determines the user's posture and head orientation, in addition to the spatial positions of the user and objects, based on images provided by the camera system 104. As a result, the system can have accurate information regarding the user's spatial orientation and can interpret movements, hand gestures, etc., which can even be used to control the operation of the system.

[0033] In a preferred embodiment of the system 100 of the present invention, if each support element 110 has its own camera 162, the signal from the camera 162 is first processed by a (concealed) local processing unit located on the rear side 114 of the support element 110, which is connected to an internal wired communication network, for example by communication using the TCP / IP protocol. The locally processed image data from the camera 162 is analyzed by a central computer 170, which is also connected to the aforementioned communication network, and preferably determines at least the spatial position of the user relative to the support element 110. In a preferred embodiment of the system 100 of the present invention, the central computer 170 generates a kinematic model of a person staying in a room based on the images acquired from the camera 162, determines the spatial position and orientation of the user, and recognizes portable electrical appliances 180 by their control gestures, movements, and optionally, it can also determine the spatial position and even the type of appliance. The latter feature is important because the power transmitted to the transmitter 120 can be controlled (e.g., limited) by the power transmission control unit 140 based on power control signals from the central computer 170.

[0034] The operation of the system 100 according to the present invention is as follows: When a user wishes to connect a portable electrical appliance 180 to a power distribution network, a dedicated wireless power supply unit, i.e., a receiver 130, must be positioned at a designated point on the inner surface of a wall, which acts as a support element 110. Since the transmitter 120 is in the aforementioned designated point in an idle position, the mounted receiver 130 is magnetically attached to the transmitter 120 through the wall. Successful attachment and communication with the concealed transmitter 120 on the rear side of the wall is preferably indicated by illumination of the receiver unit 130 with a control light such as green. The plug of the portable electrical appliance 180 can then be connected to a standard socket on the wall-mounted receiver 130. After the electrical appliance 180 is turned on, the transmitter 120 on the rear side of the wall continuously supplies the amount of electrical energy required for the receiver 130 inside the wall in a wireless manner, and the receiver 130 transmits the electrical energy to the portable electrical appliance 180 via metal contacts, i.e., via wires.

[0035] While the portable electrical appliance 180 is in use, the concealed camera 162 of the camera system 160 continuously monitors the user's spatial location, movement, and optionally the movement of the electrical appliance 180 and / or the user's movement and hand gestures, and the central computer 170, arranged on the rear side of the wall, moves the active transmitter 120 continuously by the rail system 104, so that the receiver 130 magnetically attached to it is always located in the vicinity of the user, i.e., within a predetermined distance from the user.

[0036] When the user finishes using the electrical appliance 180, the user unplugs the receiver 130 from the socket 133 and removes the receiver 130 from the wall. The transmitter 120 detects the removal of the receiver 130 by interrupting communication between control units 126 and 135, and then returns to its starting position (i.e., its idle position) by causing motors 107 and 121 to operate accordingly at a command from the central computer 170, where the receiver 130 resumes waiting for a connection. In a preferred embodiment of the system of the present invention, an LED light source hidden on the rear side of the support element 110 and dimly shining through the support element indicates the parking location of the transmitter 120, so that the user can easily position the receiver 130 on the front side of the support element 110. In addition, if the user touches the receiver 130 at any point on the front of the support element 110, the central computer 170 moves the active transmitter 120 to an appropriate location based on the camera image using the rail system 104, so that the user does not necessarily have to position the receiver 130 at the idle position indicated by the LED light source.

[0037] The method according to the present invention performs the positioning of an electrical socket in the above system. The main steps of the process are described below with reference to Figure 5.

[0038] In the first step 500, one of the transmitters 120, which is in an idle position on the rear side 112 of the support element 110, detects the magnetic fixation of the receiver 130 on the opposite front side 114 of the support element 110, which is near the transmitter 120 and is substantially the same position as the target position of the transmitter 120.

[0039] In the next step 510, power is supplied to the transmitter 120 via the power transmission control unit 140, and then in step 520, two or more cameras 162 of the camera system 160 are used to capture images of the user staying near the support element 110.

[0040] In step 522, the images from camera 162 are processed continuously by the central computer 170, and in step 524, the user's spatial position relative to the support element 110 is continuously monitored using information extracted from the images.

[0041] In step 530, following the user's movement, the target position of the transmitter 120 is continuously calculated based on the user's current spatial position, such that the distance between the user and the transmitter 120 does not exceed a predetermined value (e.g., 1.5 meters). Based on the target position of the transmitter 120, in step 540, the motion control unit 150 transmits motion control signals to the motor 107 of the movable second rail 106 and to the motor 121 of the transmitter 120, causing the motors to move the transmitter 120 to the target position. Because the transmitter 130 on the other side of the support element 110 is magnetically attached to the transmitter 120, it tracks its movement, thereby moving the receiver 130, the electrical socket forming part of the support element. In this way, with the electrical appliance 180 connected to the receiver 130 by a wire, the user can move freely within the room, subject to the limitation that the electrical appliance 180 cannot move any distance longer than the length of the wire away from the support element 110.

[0042] One of the advantageous features of the system according to the present invention is that electrical appliances can be connected to a wall-mounted receiver that can be placed inside a closet, so that the decorative appearance of the room's wall surface is not adversely affected by the electrical socket.

[0043] A further advantageous feature of the system according to the present invention is that it allows the user to move freely within a room, even when using portable electrical devices, and as a result, the user is not limited in their movement by the length of the main cable, which is typically 1 to 2 meters long.

[0044] A further advantage of the system according to the present invention is that the handheld device's own cable can be easily connected to a receiver having a standard main socket, thus eliminating the need to purchase a new electric handheld device.
