[0037] See also Figure 1 , Figure 1 FIG2 shows a perspective view of a landscape display device 100 provided in an embodiment of the present application. The landscape display device 100 shown in this embodiment is described by taking a keel 214 waterwheel as an example.

[0038] See also Figure 2 and Figure 3The landscape display device 100 includes a waterwheel assembly 2 and a light display structure 1, wherein the waterwheel assembly 2 includes a support structure 21, blades 22 and a water tank 24, the water tank 24 is provided on the support structure 21, the blades 22 are located above the water tank 24 and connected to the support structure 21, and the blades 22 can move relative to the support structure 21 and / or the water tank 24, and the number of the blades 22 is multiple; the light display structure 1 includes a light assembly 11 and a wireless power supply assembly 12, the light assembly 11 includes a light emitting unit 111 and a support 112, the light emitting unit 111 is provided on the support 112, and the support 112 is provided on the blades 22; the wireless power supply assembly 12 includes a A transmitting end 121 and a receiving end 122 electrically connected to an external power supply, wherein the receiving end 122 is electrically connected to the transmitting end 121 through a field; the receiving end 122 is arranged on the support member 112 and electrically connected to the light-emitting unit 111; the transmitting end 121 is arranged on the support structure 21 and / or the water tank 24; when the receiving end 122 is close to the transmitting end 121 and within a preset distance, the receiving end 122 is wirelessly connected to the transmitting end 121, and the light-emitting unit 111 is turned on and emits light; when the receiving end 122 is away from the transmitting end 121 and out of the preset distance, the receiving end 122 is electrically disconnected from the transmitting end 121, and the light-emitting unit 111 is turned off.

[0039] See also Figures 4 to 6 There are multiple light-emitting units 111. To enable each light-emitting unit 111 to be turned on and off individually to better display lighting effects, the number of receiving terminals 122 corresponds to the number of light-emitting units 111. This allows each light-emitting unit 111 to turn on when the corresponding receiving terminal 122 receives power and to turn off when the receiving terminal 122 is disconnected from the transmitting terminal 121. Specifically, the light-emitting units 111 are LED lamp beads that can emit various colors of light, such as white, red, and blue, as needed. The emitting side of the LED lamp bead faces outward, allowing the light to be observed. The back of the LED lamp bead is connected to the support member 112, which is provided on the blade 22 so that the LED lamp bead rotates with the blade 22, thereby producing different lighting effects as the blade 22 rotates. Each blade 22 can be provided with one, two, or more LED lamp beads, and the design can be customized according to actual needs. In this embodiment, a plurality of LED lamp beads are provided on each blade 22, and are arranged in an array. In this embodiment, a plurality refers to a number of two or more.

[0040] The blade 22 includes a mounting position 221 and a light-transmitting member 222. Specifically, the mounting position 221 is a groove provided on the blade 22. The light-transmitting member 222 covers the mounting position 221, and the light emitted by the light-emitting unit 111 can pass through the light-transmitting member 222. The light-emitting unit 111 is provided at the mounting position 221, and the light-transmitting member 222 covers the mounting position 221. The light emitted by the light-emitting unit 111 can be emitted through the light-transmitting member 222 and projected onto the water tank 24 to form a lighting effect.

[0041] The number of the transmitting terminals 121 may be more than the number of the receiving terminals 122, or may be less than the number of the receiving terminals 122, that is, one transmitting terminal 121 may correspond to one receiving terminal 122, or one transmitting terminal 121 may correspond to multiple receiving terminals 122. One transmitting terminal 121 corresponds to multiple receiving terminals 122, that is, one transmitting terminal 121 realizes radio connection with multiple receiving terminals 122, thereby providing power to multiple LED lamp beads. The field generated by the transmitting terminal 121 can be received by the receiving terminal 122, thereby realizing radio connection between the two. Specifically, the transmitting terminal 121 and the receiving terminal 122 realize radio connection through a field, and the field may be near-field coupling or far-field coupling; the two realize energy transmission through the field, thereby realizing radio connection. Specifically, in this embodiment, the transmitting terminal 121 and the receiving terminal 122 use electromagnetic induction technology to realize radio connection. When the transmitting end 121 is connected to high-frequency alternating current, an alternating magnetic field is generated. The receiving end 122 generates current through electromagnetic induction in the magnetic field, thereby powering the light-emitting unit 111, causing the light-emitting unit 111 to turn on and emit light. In order to achieve a radio connection between the two, the two need to be within a preset distance; when the preset distance is exceeded, that is, when the receiving end 122 is separated from the alternating magnetic field generated by the transmitting end 121, the receiving end 122 cannot generate current, causing the light-emitting unit 111 to turn off and not emit light. Specifically, the preset distance is less than or equal to 20 centimeters. In other embodiments, the transmitting end 121 and the receiving end 122 can also achieve a radio connection by means of magnetic resonance or radio waves, thereby controlling the turning on and off of the light-emitting unit 111. In other embodiments, the preset distance can be designed as needed.

[0042] It can be understood that when the receiving end 122 moves with the corresponding blade 22, when the blade 22 moves to the vicinity of the transmitting end 121, the corresponding receiving end 122 on the blade 22 is connected to the nearest transmitting end 121 by radio, thereby providing power to the LED lamp bead provided on the blade 22, thereby turning on and emitting light; when the blade 22 continues to move, the receiving end 122 on the blade 22 is disconnected from the transmitting end 121 with which it is radio-connected, and is connected to the next transmitting end 121 by radio, thereby continuing to supply power to the LED lamp bead. When the blade 22 moves to a position without a transmitting end 121, the receiving end 122 is separated from the field of the transmitting end 121, so that the receiving end 122 is disconnected from the transmitting end 121 by radio, thereby turning off the LED lamp bead.

[0043] In this embodiment, the transmitter 121 includes a first circuit board 1212 and a transmitter coil 1221. The first circuit board 1212 is electrically connected to the transmitter coil 1221. The first circuit board 1212 is disposed on the support structure 21 and / or the water tank 24, thereby securing the transmitter 121 to the support structure 21 and / or the water tank 24. The receiver 122 includes a second circuit board 1222 and a receiver coil 1221. The second circuit board 1222 is electrically connected to the receiver coil 1221 and the light-emitting unit 111, respectively. The second circuit board 1222 is connected to the support member 112, thereby securing the receiver 122 to the blade 22 and allowing it to move with the blade 22. In this embodiment, the transmitter coil 1221 and the receiver coil 1221 are wirelessly connected via electromagnetic induction or magnetic resonance technology. In this embodiment, the first circuit board 1212 converts input DC power into high-frequency AC power, driving the transmitting coil 1221 to generate an alternating magnetic field. The first circuit board 1212 includes an LC resonant circuit to enhance energy transmission efficiency, and a bridge inverter circuit achieves high-frequency inversion. The control chip on the first circuit board 1212 dynamically adjusts power and detects status, providing overvoltage and overcurrent protection mechanisms to ensure efficient and safe energy transmission. The receiving coil 1221 captures the alternating magnetic field from the transmitting end 121 and generates an induced current through electromagnetic induction. This current is then rectified and filtered on the second circuit board 1222 and converted into DC power to power the LEDs. The driver circuit on the second circuit board 1222 integrates a DC-DC converter to achieve a regulated output voltage, powering the LEDs and controlling their display color and on / off effects. The second circuit board 1222 also houses a control module that monitors voltage and current, dynamically adjusts charging parameters, and integrates overvoltage, overcurrent, and temperature monitoring to ensure power safety. The second circuit board 1222 is further provided with a resonant capacitor to match it with the receiving coil 1221 to improve energy coupling efficiency and achieve efficient and stable wireless power conversion and utilization.

[0044] Continue to refer to 2 and Figure 3 The waterwheel assembly 2 further includes a driving assembly 23 for driving the blades 22 to rotate relative to the support structure 21 and / or the water trough 24. The driving assembly 23 is provided with the emitting end 121. In this embodiment, the water trough 24 is fixedly connected to the end of the support structure 21 close to the ground, and the water trough 24 is fixed relative to the support structure 21; the blades 22 can rotate relative to the support structure 21 under the drive of the driving assembly 23. During the rotation of the blades 22, at least one of the blades 22 is located above the water trough 24, so that the light emitted by the LED lamp beads on the blades 22 can be projected onto the water trough 24, thereby producing various lighting effects, such as the lighting effect of flowing water, thereby avoiding the use of water flowing over the water trough 24 and avoiding the occurrence of dangerous situations caused by water flow.

[0045] Specifically, the support structure 21 includes a support bracket 211, a first support plate 212, a second support plate 213, and a keel 214. Multiple supports 211 are provided, erected on the ground, to support the landscape display device 100. The first support plate 212 is connected to the end of the support bracket 211 closest to the ground. The first support plate 212 is positioned above the water trough 24, with at least one blade 22 positioned between the water trough 24 and the first support plate 212. The second support plate 213 is connected to the support bracket 211, parallel to the first support plate 212, and located on the side of the first support plate 212 away from the water trough 24. To ensure that the light emitted by the LED lamp beads is smoothly projected onto the water tank 24, the second support plate 213, the first support plate 212, and the water tank 24 are arranged sequentially from top to bottom. Specifically, the water tank 24 is located at the end of the bracket 211 closest to the ground, the second support plate 213 is located at the end of the bracket 211 away from the ground, and the first support plate 212 is located between the second support plate 213 and the water tank 24. A keel 214 connects the multiple blades 22 in sequence. Its cross-section along the length is generally elliptical. The keel 214 and the blades 22 rotate along the periphery of the first and second support plates 212, 213, with a portion of the blades 22 always located between the first support plate 212 and the water tank 24. This ensures that a portion of the light emitted by the LED lamp beads is always projected onto the water tank 24, creating a light effect of flowing water.

[0046] The driving assembly 23 includes a driving wheel 231, a driven wheel 232, and a motor 233. The motor 233, the driving wheel 231, and the driven wheel 232 are all connected to the bracket 211 for fixation. The motor 233 is connected to the driving wheel 231 to drive the driving wheel 231 to rotate. The driving wheel 231 and the driven wheel 232 are respectively arranged at the two ends of the first support plate 212 and the second support plate 213. The elliptical structure formed by the blades 22 and the keel 214 surrounds the outside of the first support plate 212, the second support plate 213, the driving wheel 231, and the driven wheel 232. During operation, the motor 233 drives the driving wheel 231 to rotate, so that the driving wheel 231 can drive the blades 22 to rotate, and then drives the driven wheel 232 to rotate, so that the blades 22 rotate around the driving wheel 231 and the driven wheel 232. In this embodiment, in order to facilitate the motor 233 to adjust the speed when driving the driving wheel 231 to drive the blades 22 to rotate, and to match the lighting effect emitted by the light-emitting unit 111, the landscape display device 100 also includes a sensor 7. The sensor 7 is used to measure the speed and position of the blades 22 during rotation, so that the motor 233 can adjust the driving speed of the driving wheel 231 according to the rotation speed and position of the blades 22, thereby adjusting the lighting effect emitted by the light-emitting unit 111. In this embodiment, the sensor 7 is a rotary encoder, specifically, a photoelectric rotary encoder, which measures the rotation speed of the blades 22 through the principle of photoelectric conversion. In other embodiments, the driven wheel 232 can also be connected to another synchronous motor so that it can be driven to rotate.

[0047] In this embodiment, the first support plate 212, the second support plate 213, the driving wheel 231 and the driven wheel 232 are all provided with an emitting end 121, so that when the blade 22 moves to the vicinity of the first support plate 212, the second support plate 213, the driving wheel 231 and the driven wheel 232, the LED lamp beads on the blade 22 can be electrically connected, thereby emitting light and generating a light effect.

[0048] When the blades 22 move between the first support plate 212 and the water tank 24, the receiving ends 122 on this portion of the blades 22 are radio-connected to the transmitting ends 121 on the first support plate 212, causing the light-emitting units 111 on this portion of the blades 22 to turn on and emit light. When the blades 22 move to the side of the second support plate 213 away from the first support plate 212, the receiving ends 122 on this portion of the blades 22 are radio-connected to the transmitting ends 121 on the second support plate 213, causing the light-emitting units 111 on this portion of the blades 22 to turn on and emit light. When the blades 22 rotate near the driving wheel 231 or the driven wheel 232, the receiving ends 122 on this portion of the blades 22 are radio-connected to the transmitting ends 121 on the driving wheel 231 or the driven wheel 232, respectively, causing the light-emitting units 111 on this portion of the blades 22 to turn on and emit light. With such a setting, the transmitting end 121 can be set at the position where the blade 22 needs to emit light during the rotation process, so that the LED lamp beads on the blade 22 can be wirelessly charged when rotated to this position, thereby turning on and emitting light, thereby forming a lighting effect.

[0049] For example, to enhance the lighting effect, the first support plate 212, the second support plate 213 and the water tank 24 can all be made of transparent materials, so that when light is projected thereon, better lighting effects can be produced, such as breathing light effects, water flow or wave effects, etc.

[0050] In this embodiment, the brightness of the light emitted by the LED lamp beads can be designed according to actual needs, thereby forming different brightness and producing different lighting effects. To achieve this effect, please refer to Figure 7 The landscape display device 100 in this embodiment also includes a control component 3 for controlling the rotation speed of the drive component 23, so that the rotation speed of the blade 22 can be adjusted. The control component 3 can also control the power supply of the transmitter 121 and the brightness and color of the light emitted by the LED lamp beads, thereby controlling the lighting effect. Specifically, the control component 3 is electrically connected to the sensor 7, and can adjust the driving power of the drive component 23 in real time according to the rotation speed and position of the blade 22 detected by the sensor 7, thereby controlling the rotation speed of the blade 22; at the same time, the control component 3 is also electrically connected to the lighting display structure 1, specifically, the control component 3 is electrically connected to the wireless power supply component 12, thereby controlling the intensity of the energy output by the transmitter 121 of the wireless power supply component 12, thereby controlling the intensity of the electric energy received by the LED lamp beads, and then controlling the intensity and color of the light emitted by the LED lamp beads, thereby controlling the lighting effect, displaying different lighting effects, and making it more ornamental.

[0051] In order to enhance the fun and interactivity of the landscape display device 100, a pedaling assembly 4 is further provided for tourists to step on. The pedaling assembly 4 is connected to the drive assembly 23. When tourists step on the pedaling assembly 4, a driving effect can be generated on the drive assembly 23. The control assembly 3 controls the drive assembly 23 to generate different driving effects according to the speed of the stepping, thereby generating different lighting effects. For example, when the landscape display device 100 remains stationary, the tourist steps on the pedaling assembly 4 twice, and the control assembly 3 controls the drive assembly 23 to drive the driving wheel 231 to drive the blades 22 to rotate a certain distance; when the tourist steps on the pedaling assembly 4 five times, the blades 22 are driven to rotate, and the light effect emitted demonstrates the effect of water flow; when the tourist steps on the pedaling assembly 4 eight times, the blades 22 are driven to rotate at an accelerated speed, and the light effect emitted demonstrates the effect of water flow, and the light effect is brighter; the more times the tourist steps, the better the light effect produced. In other embodiments, different lighting effects can be corresponding to different numbers of stepping according to specific circumstances. The pedal assembly 4 is provided to make the landscape display device 100 more interactive, so that visitors can effectively interact with each other during their visit and increase their interest.

[0052] In order to further enhance the viewing experience and interest, and to allow users to understand the use process of the landscape display device 100, the landscape display device 100 also includes a landscape component 5 and a photoelectric component 6. The landscape component 5 includes a rice model and a soil mound model arranged near the treading component 4. When the control component 3 controls the driving component 23 to drive the blade 22 to rotate, the light emitted by the LED lamp beads forms a water flow or wave effect on the water trough 24, and can also produce the effect of water flowing to irrigate the soil mound model and the rice model, and then the rice model produces effects such as swinging, completing the use of the landscape display device 100. In order to better and more intuitively demonstrate the principle or use scenario of this model, the photoelectric component 6 can also be used for visual and auditory demonstrations, such as by setting up an LED screen and displaying the growth process of rice, animal activities in the rice field or pond on the screen, and playing sound effects, such as water flow or wave sounds, irrigation sounds, animal sounds, etc., so that visitors can intuitively and three-dimensionally experience the working process of the device, thereby better understanding the device and better experiencing the charm of historical inventions and creations. Specifically, there are two LED screens, which are respectively set on the left and right sides of the treading assembly 4, and display different images and sound effects. For example, when the landscape display device 100 is in standby mode (not turned on), the lighting effect of the lighting assembly 11 is set to a breathing state, that is, the LED lamp beads are flashing. At this time, the LED screen on the left displays the image of the puddle and the small animals swimming inside, accompanied by relevant audio, and the LED screen on the right displays the state of rice seeds soaking; when the visitor steps on the treading assembly 4 twice, the LED screen on the left displays the shaking of the water surface in the puddle, that is, the rotation of the blades 22 drives the water flow, causing the water surface of the puddle to shake, and the LED screen on the right displays the image of rice planting and audio; when the visitor steps on the treading assembly 4 five times When the visitor steps on the pedal component 4 eight times, the LED screen on the left shows the picture of the water accumulated in the water tank at one end of the trough rising, and the LED screen on the right shows the audio and video of the farmer hoeing the rice field after planting rice; when the visitor steps on the pedal component 4 eight times, the LED screen on the left shows the picture of the water accumulated in the water tank overflowing into the rice field, and the LED screen on the right shows the audio and video of irrigating the rice field; if the visitor continues to step on the pedal component 4, the LED screen on the left shows the picture of the rice maturing, and the LED screen on the right shows the audio and video of the rice harvesting, etc., thereby increasing the interactive fun with the visitors and helping the visitors understand the rice planting process and the use process of the landscape display device 100.

[0053] See also Figure 8, shows the workflow of the landscape display device 100 shown in the embodiment of the present application. When the landscape display device 100 is on standby, the waterwheel component 2 is stationary, the lighting component 11 displays a light breathing effect, and the two LED screens display animation effects such as rice fields and ponds respectively; when the treading component 4 is stepped on, the control component 3 controls the driving component 23 to drive the blades 22 to rotate, the sensor 4 detects the rotation of the blades 22, and outputs a rotation signal to the control component 3. The control component 3 controls the wireless power supply component 12 and then controls the light-emitting unit 111 to emit light, showing different lighting effects. At the same time, the control component 3 controls the photoelectric component 6 to display different audio and video. In this embodiment, the demonstration effect display time is 120S; in other embodiments, other display times can be preset. When no tourists step on the treading component 4, the control component 3 can also control the driving component 23 to drive the blades 22 to rotate for demonstration, and continuously loop the demonstration; when a tourist steps on the treading component 4, the control component 3 controls the driving component 23 and the photoelectric component 6 according to a preset program.

[0054] Compared with the prior art, the landscape display device 100 provided in the present application adds a lighting display structure 1 on the basis of the waterwheel component 2, so that the landscape display device 100 can increase the lighting effect and achieve various effects such as water flow effects through lighting, thereby eliminating the need to introduce water flow, reducing danger and providing better visual effects, and increasing entertainment and fun; in addition, the use of a wireless power supply component 12 eliminates the need for cables and wires, etc., so that the blades 22 are less affected during rotation, and can better restore the use scene of the ancient keel 214 waterwheel, which is closer to the ancient use scene and is easier for the audience to understand and appreciate.

[0055] Since the landscape display device 100 in this embodiment is powered by a wireless power supply component 12, and the number of light-emitting units 111 and receiving terminals 122 corresponds to each other and is multiple, and the number of transmitting terminals 121 of the wireless power supply component 12 is also multiple, in the process of realizing wireless power supply, each light-emitting unit 111 must be controlled to display different light intensities and light colors to display different lighting effects and achieve the expected lighting effect. Therefore, in order to ensure the lighting effect of the landscape display device 100 in this embodiment, please refer to Figure 9 The embodiment of the present application further provides a method for controlling the lighting effects of a landscape display device 100, comprising the following steps:

[0056] S1: The lighting display structure receives communication information from the control component;

[0057] S2: The lighting display structure verifies the communication information. The lighting display structure that passes the verification parses the communication information:

[0058] S3: Verify that the task in the communication information is executed through the light display structure and send a return message;

[0059] S4: Receive the rotation signal from the sensor, control the rotation speed of the blades of the landscape display device, and repeat steps S1 to S3.

[0060] Wherein, in step S1, the content of the communication message includes an address code, a function code, a data area and a cyclic redundancy check.

[0061] The address code is the first byte of the communication information. In this embodiment, it ranges from 1 to 250. There are multiple light display structures, each with a different and unique address code. The first byte indicates that the light display structure with the user-set address receives the information sent by the control component. The address code in the communication information indicates the address of the light display structure to which the communication message from the control component is sent.

[0062] The function code is the second byte in the communication information. The function code is used to inform the lighting display structure of the task content to be performed. After the task content is executed, it can be displayed externally as the light color, light intensity, output voltage, interval time, etc. emitted by the light-emitting unit. Specifically, different function codes have different definitions, and the lighting display structure performs different operations according to different function codes, and finally displays it as a lighting effect. For example, if the function code is 02, it is "reading switch input DI", and the specific operation is "reading one or more switch status input numbers (telesignaling)"; if the function code is 01, it is "reading status output OUT", and the specific operation is "reading one or more switch output status data"; if the function code is 03, it is "reading register data", and the specific operation is "reading data of one or more registers"; the function code also has other data and definitions and corresponding operations, which are no longer listed one by one in this application.

[0063] The data area contains the information or action to be sent by the light display structure. This information can include data, reference addresses, and other information. The data includes at least one of digital input / output, analog input / output, and registers. The address and data information vary from light display structure to light display structure. For example, if the control component uses function code 03 to instruct the corresponding light display structure to return the value of a register (including the starting address and length of the register to be read), the returned data will include the register's data length and content.

[0064] The cyclic redundancy check (CRC) is a highly efficient data error detection technology. In this embodiment, the CRC uses a 16-bit checksum. The CRC generates a checksum using polynomial division, balancing error detection efficiency with computational cost, making it a crucial safeguard for data reliability. Its flexible parameter configuration (e.g., polynomial and initial value) allows it to be adapted to a variety of scenarios, making it an indispensable error detection tool in digital systems. The CRC can be used to determine the accuracy of received information in control components or lighting display structures, thereby increasing the safety and efficiency of control systems.

[0065] In step S2, the corresponding light display structure is confirmed by verifying the address code, allowing the communication information to be parsed by the light display structure with the correct address code, thereby reading the information content of the function code therein for the next execution action. Due to the uniqueness of the address code in each light display structure, the communication information sent by the control component can only be received and parsed by one light display structure, thereby accurately executing the execution task of the control component and ensuring the accuracy of information transmission and execution. In this embodiment, each light display structure can accurately execute task commands such as light color, intensity, and time through the corresponding communication information, thereby enabling the lighting effects emitted by the landscape display device to display different effects, such as breathing light effects and water flow effects.

[0066] In step S3, the light display structure that passes the verification is required to perform a cyclic redundancy check before executing the task in the communication information. Only after passing the check can the task be executed. After executing the task, a return message is sent. The cyclic redundancy check further verifies the correctness of the communication information content before executing the task, ensuring the accuracy of the light display structure's execution of the task.

[0067] The return information includes an address code, function code, data field, and cyclic redundancy check (CRC). Only lighting display components that pass this check are allowed to send the return information. The address code and CRC check in the return information ensure accuracy and security, allowing the control component to determine the source of the returned information. The function code in the return information, identical to the function code in the communication information, indicates that the lighting display component that passed the check has executed the task specified in the communication information.

[0068] In step S4, the sensor is a rotary encoder, specifically a photoelectric rotary encoder, which measures the rotation speed of the blade through the principle of photoelectric conversion and outputs a rotation signal. When the control component receives the rotation signal, it calculates the rotation speed of the blade according to a preset calculation formula, so that the output of the driving component can be controlled according to a preset instruction or program, thereby controlling the rotation speed of the blade, and adjusting the lighting effect of the landscape display device 100 according to the rotation speed of the blade, that is, adjusting the lighting effect through steps S1 to S3.

[0069] In this embodiment, before data is sent, the data bus is required to remain idle for a period of time (i.e., no data is sent) greater than a preset value, which is 5 ms when the baud rate is 9600. The baud rate is a parameter in a communication system that indicates the rate at which signal symbols are transmitted. The unit is baud, i.e., the number of symbols transmitted per second. It determines the matching speed of data transmission between the communicating parties and directly affects the stability and efficiency of communication. In other embodiments, the preset value may be other time values.

[0070] In this embodiment, the light-emitting units within the light display structure emit light of varying colors and intensities based on communication information from the control assembly, thereby creating a diverse display of lighting effects. Specifically, in this embodiment, the light-emitting units achieve varying lighting effects through the coordination of a transmitter and a receiver. The transmitter is connected to a power supply, and varying the power supply's output voltage controls the current flow, thereby controlling the light intensity of the light-emitting units.

[0071] The following uses the water flow effect as an example to illustrate. In one embodiment, the first support plate 212 and the second support plate 213 are respectively provided with 10 transmitting ends 121 , the driving wheel 231 is provided with 12 transmitting coils, and the driven wheel 232 is provided with 8 transmitting ends 121 .

[0072] Among them, the 10 transmitting ends on the second support plate 213 are divided into 3 groups A1, A2, and A3 (No. 1, 5, and 9 are group A1, No. 2, 4, 6, 8, and 10 are group 2, and No. 3 and 7 are group 3), using 3 power supplies respectively. Each power supply group follows the cycle order of "high-medium-off-medium-high-..." and adopts a stable and appropriate power supply. The switching time interval is 1s, and the power supply output voltage is up to 15V 1.6A; the 10 transmitting ends on the first support plate 212 are divided into three groups B1, B2, and B3 in the same order.

[0073] The eight transmitting ends on the driven wheel 232 are divided into three groups C1, C2, and C3 (1 and 3 are group C1, 2, 4, and 6 are group C2, and 5 is group C3 with highlight), and use three power supplies respectively. Each power supply group follows the cycle order of "off-medium light-high light-medium light-off..." and adopts a stable and appropriate power supply. The switching time interval is 1s, and the maximum power output voltage is 12V 1.2A.

[0074] The 12 transmitting ends on the driving wheel 231 are divided into 3 groups D1, D2, and D3 (1, 5, and 9 are group D1, 2, 4, 6, 8, and 10 are group D2, and 3 and 7 are group D3), and use 3 power supplies respectively. Each power supply group adopts a stable and appropriate power supply in a cyclic order of "off-medium light-high light-medium light-off...", with a switching interval of 1s and a maximum power output voltage of 15V 1A.

[0075] Based on the grouping of power supplies for the flowing water light effect, all power supplies are supplied in the same cycle sequence: "high-bright-medium-off-medium-high-..." The supply voltage and current decrease from the maximum value to 0 within 2 seconds and then increase back to the maximum value. This allows the landscape display device 100 to illuminate the LED lamp beads using wireless power supply technology and achieve the breathing and flowing water effects.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
