[0002] Currently, underwater communication includes wired transmission and high-frequency wireless transmission. Wired transmission requires a wire to connect the transmitting and receiving ends.

Furthermore, severe signal interference and water shielding can cause unstable signal reception.

Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0051] One embodiment of this application provides a wireless optical communication transmission device, referencing... Figure 1 , Figure 1 This is a schematic diagram of a wireless optical communication transmission device provided in one embodiment of the present application. It should be understood that the device may also include additional structures not shown and / or the structures shown may be omitted, and the scope of the present application is not limited in this respect.

[0052] This embodiment provides a wireless optical communication transmission device comprising a bidirectional transmitter 101 and a receiver 102. Specifically, it includes at least two optical communication modules, which communicate with each other optically to achieve data transmission. Transmission and reception are achieved using different diodes (a light-emitting diode in the transmitter 101 and a photodiode in the receiver 102), resulting in low cost and stable, reliable performance.

[0053] In some embodiments, the illumination distance of the light-emitting diode of the transmitter 101 can be determined by adjusting its power, and the transmission distance can also be adjusted by adjusting the sensitivity of the photodiode of the receiver 102.

[0054] In some embodiments, the optical communication module further includes an operational amplifier chip. When the photodiode of the receiving end 102 of the optical communication module receives the invisible light signal for data transmission for optical communication based on the transmitting end 101, the operational amplifier chip converts and processes the invisible light signal based on the IrDA protocol and sends it to the controller connected to the optical communication module for identification processing of the converted invisible light signal.

[0055] In some embodiments, the optical communication module is disposed inside the waterproof seal 103. The waterproof seal 103 may be made of a corrosion-resistant material.

[0056] In some embodiments, the waterproof seal 103 further includes a waterproof light-transmitting sheet 104. When data needs to be transmitted, the transmitting end 101 of one of the optical communication modules emits infrared light or other invisible light with a wavelength range of 900nm-1000nm, which passes through the waterproof light-transmitting sheet 104 and illuminates the photodiode of the receiving end 102 of the corresponding optical communication module. Specifically, in some embodiments, there can be two layers of waterproof light-transmitting sheets 104, that is, each waterproof seal 103 is provided with at least one layer of waterproof light-transmitting sheet 104. Further, the infrared light is preferably 950nm, and the performance of different wavelengths can be referenced. Figure 2 Infrared light is determined based on the IrDA protocol, a computer network protocol that supports data transmission via far-infrared rays.

[0057] Therefore, even if there is water during the optical transmission process, it will not cause shielding or interference. Moreover, since it is in a sealed space, there is no need to worry about water entering and damaging the components.

[0058] The aforementioned device utilizes two pairs of light-emitting diodes (LEDs) and photodiodes, powered by a main unit. The transmitting end (CPU 101) controls the LEDs to turn on and off, transmitting signals in various environments. The receiving end (CPU 102) receives signals from the transmitting end by detecting changes in the current or voltage of the photodiodes. Each LED and photodiode is housed in a sealed, waterproof structure, transmitting signals via light. This allows for information transmission under waterproof, corrosion-resistant, and water-shielded conditions. Furthermore, because it employs sealed, short-range light irradiation, the signal transmission remains unaffected even when the entire device is completely submerged in water, preventing a single unit malfunction from causing the entire system to fail.

[0059] In existing technologies, electric surfboards (hydrofoils) operate in seawater. The salt content of seawater is highly corrosive to the connectors of wired transmission cables, causing signal interruptions and rendering the entire system inoperable. Repair and replacement costs are also very high. Furthermore, water is conductive, and other high-frequency wireless communication transmissions will be blocked by water.

[0060] Therefore, one embodiment of this application also provides a hydrofoil that communicates using the wireless optical communication transmission device provided with reference to the foregoing embodiments. Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of a hydrofoil that uses a wireless optical communication transmission device for communication, according to one embodiment of this application. Figure 4 The exploded view of the body portion and mast head of a hydrofoil for communication using a wireless optical communication transmission device provided in the embodiments of this application should be understood to be that the device may also include additional structures not shown and / or the structures shown may be omitted, and the scope of this application is not limited in this respect.

[0061] The hydrofoil includes a panel portion 210 and a powertrain portion 220; wherein, the panel portion 210 has a battery cavity, and the battery cavity houses a battery pack; a controller 230 is provided in the head of the mast 221 near the panel portion 210 in the powertrain portion 220, and the head of the mast 221 is plugged into the battery pack.

[0062] Specifically, such as Figure 3 As shown, a hydrofoil using a wireless optical communication transmission device includes a body portion 210 and a powertrain portion 220. The body portion 210 has a battery cavity for accommodating a battery pack. The powertrain portion 220 includes a mast 221 and a power assembly 222 connected to each other. A controller 230 is provided at the mast head of the mast 221, the end of the mast 221 away from the power assembly 222. The mast head of the mast 221 is plugged into the battery pack. For example, the mast head of the mast 221 and the battery pack can be plugged into each other using a male and female connector.

[0063] The controller 230 of the hydrofoil communicates with the battery pack via the wireless optical communication transmission device provided with reference to the foregoing embodiments, so that the controller 230 can process or store data related to the battery pack.

[0064] This ensures that the hydrofoil's communication data can be transmitted under waterproof, corrosion-resistant, and water-resistant shielding conditions. Even if the entire equipment is completely submerged in water, signal transmission will not be affected, and water ingress will not cause a single unit malfunction that renders the entire system inoperable.

[0065] In some embodiments, the wireless optical communication transmission device includes a first optical communication module 240 and a second optical communication module 250 respectively.

[0066] The first optical communication module 240 is disposed inside the mast head 221 and is communicatively connected to the controller 230. The second optical communication module 250 is disposed on the battery pack and is used to send data related to the battery pack to the first optical communication module 240 in the form of infrared light signals. The first optical communication module 240 converts the received infrared light signals through an operational amplifier chip and then transmits them to the controller 230, so that the controller can identify and process the converted infrared light signals to obtain data related to the battery pack and process or store them.

[0067] Specifically, refer to Figure 4 , Figure 5 and Figure 6 As shown, a first optical communication module 240 is installed inside the mast 221 head, and a second optical communication module 250 is installed on the battery pack. The first optical communication module 240 is communicatively connected to the controller 230. The second optical communication module 250 sends data related to the battery pack to the first optical communication module 240 in the form of optical communication. The first optical communication module 240 transmits the received data to the controller 230 so that the controller 230 can process or store the data.

[0068] In some embodiments, when the first optical communication module 240 receives the infrared light signal determined based on the IrDA protocol, it processes it into the IrDA protocol through an operational amplifier chip and sends it to the controller 230 so that the controller 230 can identify and process the infrared light signal to obtain data related to the battery pack.

[0069] In some embodiments, the first optical communication module 240 includes a first light-emitting diode and a first photodiode, and the second optical communication module 250 includes a second light-emitting diode and a second photodiode. The position of the first light-emitting diode corresponds to the position of the second photodiode, and the position of the second light-emitting diode corresponds to the position of the first photodiode.

[0070] In some embodiments, the first light-emitting diode and the first photodiode of the first optical communication module 240 are disposed within the first waterproof seal, and the second light-emitting diode and the second photodiode of the second optical communication module 250 are disposed within the second waterproof seal 251.

[0071] The first waterproof seal and the second waterproof seal 251 each include at least one waterproof light-transmitting sheet (refer to the accompanying drawings of this embodiment, including the waterproof light-transmitting sheet of the first waterproof seal and the waterproof light-transmitting sheet of the second waterproof seal 251) to allow infrared light emitted by the light-emitting diode to pass through.

[0072] In some embodiments, when the mast 221 head has data to send to the battery pack, the first light-emitting diode emits infrared light in the wavelength range of 900nm-1000nm (preferably 950nm infrared light), which passes through the waterproof light-transmitting sheet and illuminates the corresponding second photodiode. After receiving the infrared light, the second photodiode processes it through the operational amplifier chip and converts it into IrDA protocol for transmission to the CPU for identification and processing. The same applies when the battery pack has data to send to the mast 221 head.

[0073] In some embodiments, the wireless optical communication transmission device further includes a third optical communication module corresponding to the second optical communication module 250;

[0074] The third optical communication module is installed on the charger that charges the battery pack, and is used to cooperate with the second optical communication module 250 to perform optical communication between the charger and the battery pack.

[0075] Specifically, since the battery pack is equipped with a second optical communication module 250, the charger used to charge the battery pack needs to be equipped with a corresponding third optical communication module to facilitate optical communication between the charger and the battery pack.

[0076] In some embodiments, reference Figure 4 and Figure 7 The wireless optical communication transmission device further includes a fourth optical communication module 260 and a fifth optical communication module, which are correspondingly provided.

[0077] The fourth optical communication module 260 is disposed inside the mast head 221 and is communicatively connected to the controller 230. The fifth optical communication module is disposed on the board body 210 and is communicatively connected to the GPS module of the board body 210. The fifth optical communication module is used to send the data of the GPS module to the fourth communication module in the form of optical communication. The fourth optical communication module 260 transmits the received optical signal to the controller 230 through the operational amplifier chip, so that the controller 230 processes the optical signal to obtain the data of the GPS module and processes or stores it. In some embodiments, the operational amplifier chip and the one that processes the infrared light received by the first photodiode based on the IrDA protocol may not be the same operational amplifier chip.

[0078] The specific structures of the fourth optical communication module 260 and the fifth optical communication module can be similarly referenced to the first optical communication module 240 and the second optical communication module 250.

[0079] In some embodiments, the system further includes: waterproof male and female terminals for accommodating the first optical communication module 240, the second optical communication module 250, or the third optical communication module, wherein the waterproof male and female terminals include a male connector 270 capable of corresponding insertion (see reference). Figure 8 ) and female end 280 (reference) Figure 9 );in

[0080] The male end 270 is provided with two first cavities, and the first power positive and negative pole structures 272 are provided in the first cavity. The male end is provided with a hollow first optical communication interface 273.

The female end 280 is provided with a second optical communication interface 282 for accommodating the first optical communication interface 273 after plugging in.

[0082] After the male connector 270 and the female connector 280 are correspondingly inserted, the first cavity and the first optical communication interface 273 are respectively inserted into the second cavity and the second optical communication interface 282. The groove and O-ring structure increase the reliability and waterproofness of the male connector 270 and the female connector 281 after insertion.

[0083] The first optical communication interface 273 is used to accommodate the first optical communication module 240 and the third optical communication module. The second optical communication module 250 is located at the bottom of the second optical communication interface 282, thereby enabling the second optical communication module 250 to be optically connected to the first optical communication module 240 or the third optical communication module.

[0085] The first optical communication interface 273 is used to accommodate the second optical communication module 250. The first optical communication module 240 and the third optical communication module are located at the bottom of the second optical communication interface 282, thereby enabling the second optical communication module 250 to be optically connected to the first optical communication module 240 or the third optical communication module.
