[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to U.S. patent application No. 63 / 615,261, filed on December 27, 2023; and PCT application No. PCT / CN2022 / 116928, filed on September 3, 2022; and PCT / US2019 / 042729 and US6 / 605,191, filed on July 22, 2019, all of which are incorporated herein by reference in their entirety. Technical Field
[0003] The present invention relates to a power generation device, AI technology, and a communication system. The following uses skiing as an example to illustrate the main points of the invention. Background Art
[0004] Skiing is a winter sport that involves gliding across the snow using skis or snowboards. Skiing can be done on flat ground, on hillsides, or at specialized ski slopes. Skiers typically wear special boots that attach to their skis, allowing for better control of direction and speed. There are several types of skiing, including alpine skiing, which involves descending steep slopes, often using a cable car to the top and then following a marked path downhill. Cross-country skiing, which involves skiing on relatively flat terrain, either natural or man-made. Freestyle skiing, which involves performing jumps, flips, and other tricks on specially constructed slopes. Snowboarding, which is similar to skiing but uses a single board instead of two, and the movements and techniques are different. Ski jumping, which involves jumping from a high platform and then flying a distance through the air before landing. Nordic combined skiing, which combines cross-country skiing with shooting, involves athletes shooting while skiing. Skiing is not only a competitive sport but also a popular leisure activity. It can exercise the body, improve balance and coordination, and is also a great way to enjoy the winter scenery and experience the thrill.
[0005] Smart wearable devices are intelligent terminals that integrate sensors, wireless communications, and multimedia technologies. They can be worn directly on the human body and enable intelligent information exchange through built-in sensors and integrated chips. Currently, the main types of smart wearable devices include: AR / VR / MR headsets: These devices provide users with an immersive visual experience through augmented reality (AR), virtual reality (VR), or mixed reality (MR) technologies. Smart audio glasses: These glasses combine audio playback capabilities with a stylish design, allowing users to listen to music or make calls without obstructing their vision. Bluetooth headsets: These wireless headphones can provide health monitoring functions in addition to making calls and listening to music. Smartwatches: These devices offer multiple functions beyond time display, such as health monitoring, message notifications, and call answering. Health monitoring devices: These devices, such as heart rate monitors and sleep trackers, record and analyze the user's health status. Children's smartwatches: Designed specifically for children, they typically include positioning, calling, and emergency assistance functions. As a product of the mobile internet era, smart wearable devices are becoming an indispensable part of people's lives. They are not only improving convenience but also gradually changing people's health habits and communication methods. With the continuous advancement of technology, future smart wearable devices will be more intelligent and personalized, bringing richer experiences to users.
[0006] As the market develops, smart wearable devices will become more diverse, including but not limited to smart watches, smart glasses, smart shoes, smart clothing, etc. These products will meet the personalized needs and usage scenarios of different users. This invention aims to expand the application of smart wearable devices in the field of skiing.
[0007] The design requirements for smart devices in skiing equipment are quite demanding. The specific temperature and weather conditions during skiing vary depending on location and season. In some high-altitude areas or during winter, the temperature can be extremely low, even reaching dozens of degrees below zero, and there may be severe weather such as strong winds and blizzards. In such conditions, skiers need to wear thick ski clothes and goggles to protect themselves from the cold and snow. However, for skiers, the heat generated by the feet cannot keep up with the heat dissipation rate, making it easy for feet to get cold when wearing ski boots.
[0008] Smart device batteries can become less efficient in low temperatures. This is because the chemical reactions within the battery slow down in cold conditions, reducing the battery's ability to deliver power. This can cause the battery in your smart device to drain faster, or in extreme cases, even if the battery is fully charged, the device may shut down due to a power outage.
[0009] LCD screens may experience slow response at low temperatures. This is because the fluidity of the liquid crystal material deteriorates at low temperatures, affecting the speed at which pixels change, leading to problems with touchscreen functionality or display updates.
[0010] Some smart devices, such as mobile phones, may experience malfunctions in cold environments due to brittle materials or weakened lubricants, which can cause the phone to malfunction and shut down automatically. This makes using mobile phones in ski areas very inconvenient.
[0011] Furthermore, good ski areas are often remote, where there may be no communication signal. Furthermore, ski resorts are relatively empty, which poses certain safety risks when skiing.
[0012] Therefore existing technology still needs to be improved and improved.

In this way, even if the wind-incoming blades 210 stop rotating, the flywheel 220 will still drive the generator 250 to work under the action of inertia, and the power generation efficiency is high. In addition to receiving the force applied by the wind-incoming blades 210, the flywheel 220 will also drive the operation of the flywheel 220 under the action of inertia when the user moves, which is conducive to improving the power generation efficiency. The smart ski equipment as a whole is provided with a fastener 310 in the middle of the ski board body 100 for fixing the ski boots 9. Cameras 290 can also be provided at both ends of the ski board body 100 for obtaining information. The ski boots 9 are integrated with ski equipment 320. The entire ski board body 100 can be provided with an antenna, thereby increasing the range of the antenna, which is conducive to ensuring the transmission and reception of information.
[0131] Furthermore, in the self-powered skis of the smart ski equipment provided by the present invention, the diameter of the windward blades 210 on the windward side is larger than the diameter of the flywheel 220 and / or the generator 250. Generally, the diameter of the front windward blades 210 is larger, larger than the diameter of the rear windward blades 210. Furthermore, in the self-powered skis of the smart ski equipment provided by the present invention, the windward blades 210 are turbofans.
[0132] Furthermore, the self-powered skis of the smart skiing equipment provided by the present invention comprise two power components 200: a front power component 200 and a rear power component 200. The front power component 200 is located at the front end of the ski body 100, while the rear power component 200 is located at the rear end of the ski body 100. This helps maintain the balance of the skis during exercise. In particular, the diameter of the windward blades 210 of the rear power component 200 on the windward side of the self-powered skis of the smart skiing equipment provided by the present invention is larger than that of the windward blades 210 of the front power component 200. This increases the amount of air received by the rear power component 200.
[0133] Furthermore, in the self-powered ski board of the smart ski equipment provided by the present invention, the power component 200 is rotatably connected to the ski board body 100 via a rotating column 300. Furthermore, in another embodiment of the self-powered ski board of the smart ski equipment provided by the present invention, the power component 200 is ball-hinged to the ski board body 100, thereby allowing for a wider range of rotation angles.
[0134] Furthermore, in the self-generating ski board of the intelligent ski equipment provided by the present invention, the power component 200 includes a housing 260, wherein the wind-inducing blades 210, the flywheel 220, and the generator 250 are all disposed within the housing 260. Furthermore, in the self-generating ski board of the intelligent ski equipment provided by the present invention, a wind-collecting channel 270 is disposed within the housing 260. The wind-inducing blades 210 are disposed within the wind-collecting channel 270. There are two wind-inducing blades 210, one at the front and one at the rear of the wind-collecting channel 270. There are two flywheels 220, one connected to each of the two wind-inducing blades 210. The generator 250 is a double-ended generator 250. The connection structure between the rear wind-inducing blades 210 and the generator 250 is the same as that of the front wind-inducing blades 210. The present invention uses two wind-inducing blades 210, with the front blades larger than the rear blades. In conjunction with the wind-collecting channel 270, the wind force gathered at the rear end is also enhanced, thereby further increasing the efficiency of self-generating electricity.
[0135] Furthermore, the ski body is provided with a solar roof panel 280 for converting light energy into electrical energy during skiing. Preferably, the solar roof panel 280 is a flexible thin-film solar panel, which has the advantages of being lighter and able to bend with the ski body without damage. Furthermore, the ski body is provided with an energy storage component, which is electrically connected to the power component and stores the electrical energy generated by the power component. The ski body is provided with a solar roof panel for converting light energy into electrical energy during skiing. The energy storage component is electrically connected to the solar roof panel and stores the electrical energy generated by the solar roof panel.
[0136] Furthermore, the system further includes a heating component, located on the ski body where the ski boots are located. The heating component is electrically connected to the energy storage component, and the electrical energy generated by the power component is used by the heating component to keep the ski boots warm or provide heat for the working environment of electronic devices. Furthermore, the system further includes a temperature control component, which is electrically connected to the heating component. Furthermore, the system further includes a temperature sensing component, which is electrically connected to the heating component. Furthermore, the heating component is a PTC heater; the PTC heater is composed of multiple independent PTC plates, which can be controlled by the temperature control component to more intelligently heat the ski equipment. Furthermore, the temperature control component includes an online detection module and an offline detection module, which are used in online and offline detection scenarios, respectively. The online detection module is used to measure the voltage and current of the PTC heater during the heating process, and then obtain a corresponding temperature value as the measured temperature based on the calculated resistance value. The offline detection module is used to connect the PTC heater to a resistance measurement circuit to obtain a resistance value, and then obtain a corresponding temperature value as the measured temperature based on the resistance value. Furthermore, the target temperature of the temperature control component is a fixed value or calculated according to temperature control logic. Furthermore, the temperature control logic includes: obtaining meteorological parameters of the scene where the ski equipment is located, including data such as temperature, wind speed, wind direction, and air pressure, and determining the target temperature of the heating component based on the meteorological parameters and a preset temperature determination algorithm; or, the temperature control logic includes: an online detection module that can implement the temperature control logic of the offline detection module on the server side and can adjust the target temperature according to the skier's temperature preference.
[0137] As shown in Figures 6.1 and 7, the power generation device provided by the present invention for use in smart skiing equipment includes a pressure power generation component 1 for collecting electrical energy from the pressure applied by the skier from the soles of the skier's feet and the front of the lower calves during skiing, and a charging circuit for delivering electrical energy to electrical components. The pressure power generation component 1 is electrically connected to the charging circuit.
[0138] It is understood that during skiing, the basic skiing motion exerts two pressures on the snowshoes: one is squatting, where the entire body exerts force through the thighs, calves, and feet, ultimately exerting downward force on the soles of the snowshoes; the other is leaning forward, where the entire body exerts force through the front of the lower calf (above the ankle), ultimately exerting force against the inner side of the snowshoe tongue. Therefore, the pressure from the soles of the skier's feet and the front of the lower calf can press the pressure-generating assembly 1 to generate electricity, allowing the electrical energy to be used to power the electrical components through the charging circuit.
[0139] Compared with the existing technology, the present application can use the pressure power generation component 1 to generate electricity during the skiing process through the skier's own gravity, thereby generating electrical energy. This process requires additional charging of the ski boots 9 to power the electrical components on the ski boots 9.
[0140] In one embodiment, as shown in Figures 6.1-6.2, 7, 8, 9 and 10, the ski equipment is a ski board, the pressure power generation component 1 includes a covering 2 fixed to the ski equipment, and the ski boots 9 on the ski equipment are located in the covering 2. Pressure power generation components 3 are provided on the ski equipment and below the ski boots 9, as well as on the inner side of the covering 2 at one end of the tongue of the ski boots 9. Pressing components 4 for pressing the pressure components are provided at the bottom of the ski boots 9 and at one end of the tongue of the ski boots 9, and the ski boots 9 and the covering 2 are slidable up and down. The electric energy generated by the pressure power generation component 1 can be used to keep the ski boots warm.
[0141] It should be noted that the range of the upward and downward sliding of the ski boots 9 and the covering 2 is relatively small, so that when the ski boots 9 slide upward and downward relative to the covering 2, the pressing member 4 always maintains contact with the pressure generating member 3.
[0142] It can be understood that when a skier is skiing, the skier's feet will apply pressing pressure to the bottom of the ski boots 9 and to the inner side of the tongue of the ski boots 9. The above two pressures respectively press the pressure generator 3 repeatedly, thereby causing the pressure generator 3 to generate electrical energy.
[0143] Furthermore, the pressure power generating element 3 includes a pot piece, a ceramic piece and a copper piece stacked in sequence from top to bottom, wherein the pot piece corresponds to the pressing piece 4 in the vertical direction, and the ceramic piece and the copper piece are respectively connected to the charging circuit to form a loop with the power supply component.
[0144] It should be noted that the structure and working principle of the pressure power generation element 3 for realizing pressure power generation are well known to those skilled in the art, and do not belong to the core improvement part of this application, so they will not be described here in detail.
[0145] Furthermore, a slide rail 6 is provided on the inner side wall of the covering member 2 and is slidably arranged with respect to the clamping member on the outer side of the ski board.
[0146] Preferably, a compression spring 7 is disposed within the slide rail 6, one end of the compression spring 7 being fixed to the slide rail 6, and the other end of the compression spring 7 being fixed to the clamp. When a skier is skiing on the snow, the pressing member 4 is always in contact with the pressure generator 3, and the compression spring 7 acts to constantly change the pressing force applied to the bottom of the ski boot 9 during the skiing process. The compression spring 7 is capable of achieving a large fluctuation in the amplitude of the pressing force, which in turn increases the power generation efficiency of the pressure generator 3.
[0147] Preferably, four slide rails 6 are provided, one on each of the inner sidewalls of the left and right ends of the cover 2. It is understood that the ski boots 9 are provided with clamps on all four sides for sliding with the slide rails 6, which is equivalent to providing force-bearing parts on all four sides of the ski boots 9. This ensures that when the skier is skiing, the ski boots 9 slide up and down relative to the cover 2, while the pressing member 4 presses the pressure generator 3 more effectively.
[0148] Furthermore, the slide rail 6 is arranged non-vertically. Preferably, with the midpoint of the slide rail 6 as the center, the upper end of the slide rail 6 is located in the second quadrant, and the lower end of the slide rail 6 is located in the third quadrant.
[0149] It can be understood that, since the front end and bottom of the ski boots 9 will be squeezed by the skier's feet when the skier slides forward, in order to prevent the skier from falling while skiing and to fully utilize the squeezing force on the front end and bottom of the ski boots 9 to be converted into electrical energy, the squeezing force of the pressing part 4 on the pressure generating part 3 is non-vertically set, so that when the skier slides forward, the squeezing force on the front end and bottom of the ski boots 9 is converted into squeezing force of the pressing part 4 on the pressure generating part 3, that is, it can effectively improve the power generation efficiency of the pressure generating part 3, and can also prevent the skier from falling when the ski boots 9 of the skier slide up and down relative to the covering part 2.
[0150] It should be noted that, since the skier's feet are restricted by the internal space of the ski boots 9, the amplitude of the pressing force exerted by the front of the skier's lower calf (upper ankle) on the inner side of the tongue of the ski boot 9 during skiing fluctuates less. However, the slide rail 6 and the compression spring 7 can make the amplitude of the pressing force exerted by the pressing part 4 at one end of the tongue of the ski boot 9 on the pressure generator 3 fluctuate more. That is, the slide rail can increase the pressing amplitude of the pressing part 4 at one end of the tongue of the ski boot 9 on the pressure generator 3, so that the power generation efficiency of the pressure generator 3 is better.
[0151] Furthermore, since the slide rail 6 is not vertically arranged, the prerequisite for the ski boots 9 to be able to slide relative to the covering 2 is that a gap is provided between the inner wall of the covering 2 and the ski boots 9, and the gap can provide the space required for the ski boots 9 to slide relative to the covering 2.
[0152] Furthermore, a seal 8 is provided between the upper end of the cover 2 and the ski boot 9. It is understood that due to the gap between the cover 2 and the ski boot 9, dirt and gravel can easily enter the gap, thereby damaging the ski boot 9. The seal 8 can be used to prevent dirt and gravel from entering the gap, ensuring that the ski boot 9 can be used normally.
[0153] Preferably, the seal 8 is a flexible seal 8. Since the ski boots 9 can slide up and down relative to the covering 2, the seal 8 will be pulled when the ski boots 9 can slide up and down relative to the covering 2, that is, the seal 8 is a flexible seal 8, which can prevent the seal 8 from being torn.
[0154] Furthermore, the pressing member 4 includes a pressing body and a pressing head provided in contact with the pressure power generating member, and the pressing head and the pressing body are connected by an elastic member. Furthermore, a power generating device is connected to the side of the pressing body. Furthermore, as shown in FIG6.2, a bar gear 910 is provided on the side of the pressing body, and the power generating device includes a speed-changing gear set, a transmission shaft 911, a generator, a first flywheel 912 and a second flywheel 913. The two ends of the transmission shaft 911 are respectively provided with a first bevel gear 914 and a second bevel gear 915. The tooth groove direction of the bar rack 910 is about 45 degrees to the transmission shaft 911, so as to facilitate engagement with the first bevel gear 914, and the second bevel gear 915 is engaged with the speed-changing gear set, and the speed-changing gear set is engaged with the first The outer gear of the flywheel 912 is meshed, the inner side of the first flywheel 912 is provided with a row of teeth 916, and the second flywheel 913 is provided with a pawl 917. The second flywheel 913 is located inside the first flywheel 912. The first flywheel 912 is fixed to the rotating shaft of the generator, and the second flywheel 913 is not fixed to the first flywheel 912. The pawl 917 is meshed with the row of teeth 916. When the second flywheel 913 rotates counterclockwise, the pawl 917 acts on the row of teeth 916 to drive the rotation of the first flywheel 912. When the second flywheel 913 stops or rotates clockwise, the pawl 917 cannot mesh with the row of teeth 916, and thus does not affect the counterclockwise rotation of the first flywheel 912.
[0155] Furthermore, the rotation of the first flywheel 912 can drive a generator to generate electricity. A typical solution involves mounting a magnet on the inner wall of the first flywheel 912, which rotates simultaneously with the flywheel. A stationary coil is mounted within the flywheel. The rotation of the magnet creates an effect where the coil cuts through magnetic lines of force, thereby generating electricity. Other electromagnetic power generation mechanisms based on similar principles may also be used, and are not limited here.
[0156] Furthermore, the speed gear set includes a first gear 918, a second gear 919 and a third gear 920, the first gear 918 is provided with a third bevel gear 921, the second gear 919 is provided with a first driven pinion 922, the third gear 920 is provided with a second driven pinion 923, the second bevel gear 915 is meshed with the third bevel gear 921, the first gear 918 is meshed with the first driven pinion 922, the second gear 919 is meshed with the second driven pinion 923, and the third gear 920 is meshed with the second flywheel 913.
[0157] It can be understood that the first bevel gear 914 is driven to rotate by the bar gear 910 on the pressing member, thereby driving the second bevel gear 915 to rotate, so that the first gear 918 is rotated, and then the first gear 918 drives the first driven pinion 922 to rotate, and the rotation of the first driven pinion 922 is the rotation of the second gear 919, and the second gear 919 drives the second driven pinion 923 to rotate, so that the third gear 920 is rotated, and the third gear 920 drives the second flywheel 913 to rotate. Under the action of the pawl 917 and the row of teeth 916, the second flywheel 913 can continuously keep the first flywheel 912 rotating in one direction, that is, when the pressing member 4 is repeatedly pressed by external force, the generator can continue to generate electricity.
[0158] As another implementation, the first bevel gear 914 can also be a spur gear. In this case, the bar gear 910 on the side of the pressing body 4 uses ordinary bar teeth, and the tooth groove direction is parallel to the transmission shaft 911. The spur gear directly meshes with the ordinary bar teeth.
[0159] It should be noted that the transmission mechanism can cause flywheel 912 to rotate multiple times by moving pinion gear 910 a very small distance. To achieve optimal power generation efficiency, a variable number of gear sets or an equivalent speed transmission mechanism can be used between flywheel 912 and pinion gear 910, with each gear set optionally having a different speed ratio. This is sufficient as long as the final drive direction of the multiple gear sets ensures that first flywheel 912 rotates counterclockwise. Of course, if counterclockwise rotation of first flywheel 912 cannot be guaranteed, the direction of pawl 917 and row of teeth 916 can be changed to cause first flywheel 912 to rotate clockwise.
[0160] It should be noted that the pressing member can be pressed repeatedly by the elastic member between the pressing head and the pressing body.
[0161] As shown in Figures 11.1, 11.2, 12 and 13, the present invention also provides a power generation device for intelligent skiing equipment, including an arc-shaped pressure power generation sheet, which includes a metal substrate 21, a piezoelectric ceramic 22 and an insulating tape 23. The metal substrate 21 is arc-shaped, the piezoelectric ceramic 22 is arranged on the metal substrate 21, and the insulating tape 23 is arranged on the edge of the metal substrate 21.
[0162] The metal substrate 21 is used to support the piezoelectric ceramic 22 and the insulating tape 23. The metal substrate 21 is arc-shaped, and the curvature is close to the curvature of the inner wall of the snowshoe. The metal substrate 21 can deform along the arc direction; the piezoelectric ceramic 22 deforms along with the metal substrate 21 and generates electrical energy during the deformation process; the insulating tape 23 at the edge of the power generation sheet is used to prevent direct contact with the metal substrate 21 when multiple power generation sheets are stacked.
[0163] The piezoelectric device applied to the intelligent skiing equipment of the present invention comprises a plurality of arc-shaped pressure power generation sheets, which are stacked layer by layer to form a pressure power generation group.
[0164] The piezoelectric ceramic 22 of an arc-shaped pressure power generation sheet is directly connected to the metal substrate 21 adjacent to the arc-shaped pressure power generation sheet. Multiple power generation sheets form a series circuit, and the final output electrode 28 is led out on the two power generation sheets located on the outside. The voltage output by the electrode is the sum of the power generation voltages of multiple arc-shaped pressure power generation sheets.
[0165] A rigid support member 25 is fixed in the center of the arc-shaped outer side of the pressure power generation group 24, and the rigid support member 25 is fixed to the inside of the shoe. A certain bending space 27 is left between the arc-shaped outer side of the pressure power generation group 24 and the shoe upper 26. When the skier's legs apply pressure along the force direction on the inner side of the arc, the pressure power generation group 24 deforms along the bending direction. When the pressure applied by the legs is removed, the pressure power generation group 24 recovers by its own toughness. The power generation sheet generates electrical energy during the two processes of deformation and recovery.
[0166] As another embodiment, an insulating layer is placed between multiple arc-shaped pressure power generation sheets, the metal substrates 21 of all the power generation sheets are connected together to lead out an electrode, and the piezoelectric ceramics 22 of all the power generation sheets are connected together to lead out another electrode. At this time, the voltage output by the electrode is basically the same as the voltage of a single power generation sheet, but the current is the sum of the currents generated by all the power generation sheets.
[0167] Four pressure generators 24 are installed on the inner wall of the snowshoe, one in each of the four directions: front, back, left, and right. This allows electricity to be generated and collected regardless of the direction in which the skier applies pressure to the snowshoe. The electrodes between the pressure generators 24 are connected in series via wires, ultimately resulting in only one electrode generating output. Because the deformation / bending distance of the pressure generators 24 is minimal, it does not affect skiing movements. The pressure generators 24 generate electricity from the natural, repeated pressure exerted by the skier on the snowshoe during movement, eliminating the need for the skier to deliberately or subjectively apply pressure. Maximum efficiency in power output is achieved by varying the number and shape of the multi-layered curved pressure generator sheets, the toughness of the individual sheets, and the thickness and material of the piezoelectric ceramic 22.
[0168] In another embodiment, the output electrodes of multiple pressure-generating groups 24 are connected in parallel. In another embodiment, the output electrodes of multiple pressure-generating groups 24 are connected in parallel after passing through a rectifier circuit. In this case, when only a few groups are generating electricity, the remaining groups do not consume additional energy. In another embodiment, the same multi-layered generator sheet design can also be used between the sole of a snowshoe and the snowboard.
[0169] In order to improve the safety of users skiing, the present invention also provides a motion guidance method for smart skiing equipment.
[0170] Please refer to Figure 14, which is a flow chart of an embodiment of the method for guiding the movement of intelligent skiing equipment provided by the present invention. As shown in Figure 14, the method includes the following steps:
[0171] S101, obtaining skiing information data of a skier;
[0172] S102, inputting the skiing information data into a pre-trained AI action recognition model, wherein the AI action recognition model outputs the skier's skiing action based on the skiing information data;
[0173] S103: Compare the skiing action with the preset standard action for the scene, and guide the skier's action according to the preset standard action for the scene.
[0174] In this embodiment, a skier's skiing information data is obtained and input into a pre-trained AI action recognition model. The AI action recognition model can be trained using various deep learning models, such as CNN, RNN, GAN, LSTM, and attention mechanisms. The AI action recognition model outputs the skier's skiing movements based on the skiing information data, compares the skier's skiing movements with standard movements for the specific scenario, and provides reminders based on the pre-set standard movements for the scenario. The snowshoe device is connected to the ski pole via short-range wireless communication. Sensor data collected from the ski pole is centrally analyzed and then sent to the skier via the ski pole, providing convenient guidance on skiing movements.
[0175] In one embodiment, the ski information data includes:
[0176] skiing videos and / or skiing images captured by camera equipment on ski equipment;
[0177] ski pole movements captured by sensors installed on ski equipment;
[0178] The skier's skiing posture is obtained by the posture sensor installed on the ski equipment.
[0179] In this embodiment, the skiing information data includes skiing videos and / or skiing images of the skier obtained through one or more cameras on the ski equipment; ski pole movements obtained through sensors installed on the ski equipment; and skiing posture of the skier obtained through posture sensors installed on the ski equipment.
[0180] Furthermore, wide-angle cameras are installed at the nose and tail of the skis in the ski equipment. The cameras are installed at a certain angle upwards. Due to the large lens angle, a complete image of the skier can be captured, and the two cameras can capture the skier's torso and limbs from different angles. It is preferred to use a depth camera to obtain more accurate trunk and limb sampling data. Compared with installing sensors on the skier's torso and limbs, it is more convenient and the recognition effect is more ideal. The depth camera sampling is more accurate for the input data of the AI recognition model. The two cameras transmit the video convergence to the snowshoe equipment through short-range high-speed wireless communication. The snowshoe equipment uses the video data and posture sensor through the AI algorithm to calculate the skier's posture, movement and other information to accurately identify the skiing movements.
[0181] In one embodiment, step S102 includes:
[0182] The AI action recognition model identifies several local postures of the skier based on the skiing information data;
[0183] constructing an overall posture of the skier based on the plurality of local postures;
[0184] The skier's skiing movements are outputted through the overall posture.
[0185] In this embodiment, the AI motion recognition model identifies several local positions of the skier based on the input skiing information data, constructs the skier's overall posture based on these identified local positions, and then synthesizes the skier's overall posture and input data that are not part of the posture parameters to obtain the skier's skiing motion. In conjunction with the posture sensor, the AI motion recognition model analyzes the skier's skiing posture and motion, improving the accuracy of skiing motion recognition.
[0186] In one embodiment, the scene preset standard action is obtained by the following steps:
[0187] Obtain a target video recording skiing movements;
[0188] The target video is input into a pre-trained deep learning model based on the self-attention mechanism to obtain the standard skiing movements in the target video.
[0189] In this embodiment, an AI action recognition model is constructed based on a self-attention mechanism and is used to implement skiing action recognition based on the self-attention mechanism. A skiing video recording skiing actions is obtained and the target video is input into a pre-trained deep learning model based on the self-attention mechanism to obtain the standard actions of the skier in the skiing video. The query matrix, key-value matrix, and value matrix in the deep learning model of the self-attention mechanism are determined through learning. A vector matrix is extracted from the target video as input. This vector matrix is multiplied with the query matrix, key-value matrix, and value matrix to obtain the corresponding result matrix. The query matrix's i-th row is then multiplied with the result matrix corresponding to the association matrix. After passing an activation function, the result matrix is multiplied with the value matrix of the vector matrix to obtain an eigenvalue. Based on this eigenvalue, the corresponding standard action of the skier is obtained. The deep learning model is used to characterize the correspondence between the video recording the skier's skiing process and the skier's standard action. This method of skiing action recognition based on the self-attention mechanism has fast detection speed and high accuracy.
[0190] In one embodiment, before step S103, the following steps are included:
[0191] Get the ski slope parameter information of the ski scene;
[0192] Determining standard actions corresponding to a number of snow track positions according to the snow track parameter information;
[0193] The optimal posture of the ski equipment is determined according to the ski track parameters and the skiing action of the skier.
[0194] In this embodiment, posture calculation is based on the fusion of multiple data from posture sensors. Since a skiing maneuver can have different postures, a fuzzy control algorithm can be used to map quantitative posture data into skiing maneuvers, thus avoiding the technical problem of inaccurate recognition caused by fluctuations in posture data. This maneuver guidance method also includes determining a standard skiing maneuver. This standard maneuver is determined based on the parameters of the ski slope, corresponding to a number of standard maneuvers. This determination method includes two methods: one approach uses big data technology to obtain the skiing trajectory and posture control corresponding to the fastest speed on the current ski slope as the standard maneuver for that slope. The other approach determines the skiing trajectory based on the ski slope parameters, determines the motion parameters for each trajectory segment based on the skiing trajectory parameters, and determines the standard maneuver based on the feedback from executing the motion parameters. Furthermore, the optimal posture of the skiing equipment is determined based on the ski slope parameters and the skier's control movements. For example, the current state parameters and force conditions of the skiing equipment are obtained, and the skier's intended maneuver is determined based on the force conditions. The optimal leading edge angle or trailing edge angle is determined based on the intended maneuver, the current speed, and the slope at the current position.
[0195] Another embodiment of the present invention further provides a motion guidance device for intelligent skiing equipment, as shown in FIG15 , the device includes:
[0196] A data acquisition module 11 is used to acquire skiing information data of a skier;
[0197] a motion recognition module 12, configured to input the skiing information data into a pre-trained AI motion recognition model, wherein the AI motion recognition model outputs the skier's skiing motion according to the skiing information data;
[0198] The action guidance module 13 is used to compare the skiing action with the preset standard action of the scene, and guide the skier's action according to the preset standard action of the scene.
[0199] The module referred to in the present invention refers to a series of computer program instruction segments that can perform specific functions. It is more suitable for the execution process of the action guidance method of intelligent skiing equipment than a program. For the specific implementation of each module, please refer to the corresponding method embodiment above, which will not be repeated here.
[0200] Another embodiment of the present invention further provides a motion guidance system for intelligent skiing equipment. As shown in FIG16 , the system 10 includes:
[0201] One or more processors 110 and memory 120. FIG16 takes one processor 110 as an example for introduction. The processor 110 and the memory 120 may be connected via a bus or other means. FIG16 takes the bus connection as an example.
[0202] Processor 110 is used to implement various control logic of system 10. It can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a single-chip microcomputer, an ARM (Acorn RISC Machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components. In addition, processor 110 can also be any conventional processor, microprocessor, or state machine. Processor 110 can also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in combination with a DSP, and / or any other such configuration.
[0203] Memory 120, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs, non-volatile computer-executable programs, and modules, such as the program instructions corresponding to the motion guidance method for intelligent skiing equipment in the embodiments of the present invention.

[0204] Memory 120 may include a program storage area and a data storage area. The program storage area may store an operating system and application programs required for at least one function; the data storage area may store data created based on the use of system 10, etc. In addition, memory 120 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other non-volatile solid-state storage device. In some embodiments, memory 120 may optionally include memory remotely located relative to processor 110, and such remote memory may be connected to system 10 via a network. Examples of such networks include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.
[0205] One or more units are stored in the memory 120 and, when executed by one or more processors 110, perform the action guidance method in any of the above method embodiments, for example, execute steps S101 to S103 of the method described above in FIG. 14 .
[0206] An embodiment of the present invention provides a non-volatile computer-readable storage medium, which stores computer-executable instructions. The computer-executable instructions are executed by one or more processors, for example, executing steps S101 to S103 of the method described above in Figure 14.
[0207] As examples, non-volatile storage media can include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM) as external cache memory. By way of illustration and not limitation, RAM can be obtained in many forms such as synchronous RAM (SRAM), dynamic RAM, (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). The disclosed memory components or memories of the operating environment described herein are intended to include one or more of these and / or any other suitable types of memory.
[0208] In order to replace mobile phones to implement communication-related functions, the present invention provides a communication system for smart skiing equipment, including:
[0209] Through technologies such as eSIM, all functions of the mobile phone can be automatically transferred to the snowshoe before the phone stops working, and the transfer can also be manually operated.
[0210] an equipment management module, configured to connect to a skier's skiing equipment and obtain skiing information data of the skier through the skiing equipment, wherein the skiing equipment includes skiing equipment and electronic equipment;
[0211] The safety protection module is used to receive the skiing information data of the skier transmitted by the equipment management module, and determine whether the skier is safe based on the skiing information data.
[0212] In this embodiment, the device management module is connected to all of a skier's ski equipment. The ski equipment includes ski equipment and electronic devices, including smart ski poles, a biometric watch, a smart wearable device, or a mobile phone. Wearable devices include smart helmets, smart ski suits, smart gloves, and smart glasses. Ski equipment includes ski boots and skis. The device management module obtains skiing information data from the skier's ski equipment. The skiing information data is then transmitted to the safety protection module, which determines whether the skier is safe based on the skiing information data.
[0213] Since carrying other equipment while skiing isn't always practical, or using a phone can be inconvenient in cold temperatures, integrating some smartphone functionality into ski gear, such as smart helmets or smart ski suits, is a viable option. By placing a display on the front of the skis or on the helmet's front mirror, communication needs during skiing can be met. Specifically, using an eSIM or other technical solutions, mobile phone functions can be transferred to ski equipment, such as snowshoes, and displayed on the ski equipment's display, effectively replacing the phone's functionality. Simple actions, such as tapping the helmet to answer or end a call, can be performed, while more complex operations can be performed with voice commands. Reflecting skiing's demand for VR technology, smart ski goggles can support high-definition photography and video recording. A location inside the lenses of the goggles can also display basic skiing data, such as timing, slope, wind direction, wind speed, temperature, speed, weather, and terrain.
[0214] In one embodiment, the equipment management module establishes a connection with the ski equipment in the following manner:
[0215] The communication link with the ski equipment is a first communication channel, and the communication link with the electronic device is a second communication channel;
[0216] The first communication channel and the second communication channel are mutually primary and backup, and there is a communication interaction link between the electronic device and the skiing equipment.
[0217] In this embodiment, the communication link between the skiing equipment and the multimode gateway serves as the first communication channel, while the communication link between the skier's electronic device and the multimode gateway serves as the second communication channel. These first and second communication channels serve as primary and backup channels, reducing the probability of communication interruption. A communication link exists between the electronic device and the skiing equipment. As shown in Figure 17, the Vital Signs watch has multiple built-in sensors. For example, a temperature sensor measures the wearer's temperature at the wrist, typically using contact temperature sensors and infrared temperature sensors; a heart rate sensor measures the wearer's heart rate using the PPG method; and a posture sensor measures the wearer's inclination, acceleration, angular velocity, and direction of movement. The Vital Signs watch includes a communication module, enabling it to implement the aforementioned primary and backup communication functions of the electronic device, as well as human-body communication. The Vital Signs watch also features an SOS button. When the user needs emergency assistance, they can press the SOS button, which then sends a distress message to the multimode gateway.
[0218] In some embodiments, a smart helmet is provided, comprising a helmet body and a sensor assembly for smart skiing equipment mounted on the helmet body. The sensors in the sensor assembly can be mounted using a plurality of mounting holes or slots. The helmet body is also provided with connection components for other electronic devices, such as a mechanical mechanism for mounting smart ski goggles and communication contacts to enable communication and data sharing with the goggles.
[0219] Since carrying other equipment while skiing isn't always convenient, or using a phone can be difficult in cold weather, integrating some of the functionality of a smartphone into a smart helmet or smart ski suit could be a viable option. Placing a display on the front of the skis or on the helmet's front mirror would facilitate communication needs during skiing. This functionality is achieved by extracting information from the phone and displaying it on the device's screen. Simple actions can be performed through gestures, such as tapping the helmet to answer or end a call. Complex operations can also be performed through voice commands. Given skiing's demand for VR technology, smart ski goggles can support high-definition photography and video recording. Furthermore, a location inside the lenses of the goggles can display simple ski-related data, such as timing, slope, wind direction, wind speed, temperature, speed, weather, and terrain.
[0220] In one embodiment, as shown in FIG21 , the device management module further includes:
[0221] A temperature control unit is used to monitor the temperature of the ski equipment and heat the ski equipment.
[0222] In this embodiment, a heating system for intelligent skiing equipment includes a power supply component, a temperature control component, and a heating unit. The skiing equipment includes snowshoes. The heating unit is mounted on the snowshoes and is used to heat the snowshoes. The power supply component is used to supply power to the heating unit, and the temperature control component is used to adjust the power of the heating unit to more intelligently heat the snowshoes.
[0223] Preferably, the power supply is a low-temperature rechargeable battery; the heating component is preferably a PTC heater; preferably, the PTC heater is composed of multiple independent PTC plates, which can be controlled by the temperature control component to more intelligently heat the ski equipment. The power supply is preferably a low-temperature rechargeable battery, and further, the power supply is derived from the aforementioned power generation device for smart ski equipment; the heating component is preferably a PTC heater.
[0224] Preferably, the PTC heater is composed of multiple independent PTC plates, which can be controlled by a temperature control component to heat the ski equipment more intelligently; the temperature control component includes an online detection module and an offline detection module, which are used in online detection scenarios and offline detection scenarios respectively. Among them, the online detection module is used to measure the voltage and current of the PTC heater during the heating process, and then obtain the corresponding temperature value as the measured temperature based on the calculated resistance value. The offline detection module is used to connect the PTC heater to the resistance measurement circuit to obtain the resistance value through measurement, and obtain the corresponding temperature value as the measured temperature based on the resistance value. The target temperature of the temperature control component can be a fixed value or calculated according to the temperature control logic.
[0225] Preferably, the temperature control logic includes obtaining meteorological parameters of the ski equipment's location, including temperature, wind speed, wind direction, and air pressure, and determining the target temperature of the heating component based on these meteorological parameters and a preset temperature determination algorithm. This solves the problem of poor adaptability when using a set target temperature for control, enhancing skier comfort.
[0226] Preferably, another temperature control logic includes: the online detection module can implement the temperature control logic of the offline detection module on the server side and adjust the target temperature according to the skier's temperature preference. This method integrates big data technology with the temperature control logic of the offline detection module, and is more tailored to the skier's comfortable temperature perception.
[0227] The contact electrodes detect whether the ski and snowshoe are connected. The temperature control component provides heating control and temperature feedback. PTC heating converts electrical energy into thermal energy. The heating control and temperature feedback circuits control the PTC heater to heat the snowshoe. The heating temperature is controlled through a closed-loop temperature detection loop. Temperature detection is achieved by directly measuring the resistance of the PTC heater at different temperatures. Compared to using a separate temperature sensor, direct temperature measurement with the PTC heater provides a larger correlation area and is closer to the actual value. It also eliminates the need for additional wiring, making the system more reliable.
[0228] Temperature detection uses both online and offline methods. Specifically, online monitoring involves measuring the voltage and current across the PTC heater while it's powered on. The resistance of the PTC heater is then calculated using Ohm's law (R = U / I). The current temperature is then obtained from the PTC heater's temperature-resistance curve using a lookup table. Since online detection requires power to the PTC heater for measurement, if the actual temperature exceeds the target temperature, the measurement will cause the temperature to rise further. In this case, offline detection is more appropriate. This involves connecting the PTC heater to a resistance measurement circuit to measure resistance. Since the current flowing through the resistance measurement circuit is low, virtually no excess heat is generated in the PTC heater. Typical resistance measurement circuits include the bridge method and the four-phase resistance method.
[0229] The snowshoe's main board also features functions such as snowboard detachment detection, position positioning, and posture sensing, all of which are implemented using sensors from the sensor suite used in smart skiing equipment. The posture sensor, which can consist of one or more sensors such as an accelerometer, an angular velocity sensor, and an electronic compass, identifies the snowshoe's inclination, acceleration, angular velocity, and direction of movement. The inclination angle can be used to analyze dangerous situations such as falls or handstands. The left and right snowshoes each detect movement and aggregate the results via a wireless communication module. This aggregated data can be used to analyze conditions such as snowshoe detachment and abnormal foot posture, generating alarms. The snowshoe device connects to the ski poles via short-range wireless communication, collecting sensor data collected by the poles for centralized analysis. The snowshoe device can connect to a mobile phone via Bluetooth or WiFi and establish a connection to a server via a mobile gateway. Positioning information and sensor data can be shared between the snowshoe device and the mobile phone. The mobile phone includes a dedicated app that collects all skier status data and provides connectivity to the server.
[0230] In one embodiment, the security protection module further includes:
[0231] The multi-mode gateway unit is used to obtain the location information and communication status of the signal source based on the analysis of the received ski information data.
[0232] The beacon timing equipment unit is used to record the beacon update status of the ski equipment and generate corresponding alarms based on the update status.
[0233] In this embodiment, a plurality of multimode gateways are distributed throughout the venue. The multimode gateways analyze received signals to obtain location information and communication status of the ski equipment as the transmitter. Beacon timing equipment is also provided. The beacon timing equipment is located within the multimode gateway or server and is used to record the beacon update status of the ski equipment and generate corresponding alarms based on the beacon update status. The multimode gateways are configured to: respond to beacons in short-range and long-range modes; obtain the location information of the beacon transmitter based on the long-range mode beacon; and analyze the alarm information and voice information in the beacon. The beacon timing equipment is configured to: reset the timing duration of the beacon transmitter after receiving a beacon, and issue a beacon timeout alarm for beacon transmitters whose timing duration exceeds a preset time. The received beacon is analyzed, and the distance or location of the transmitter is determined based on the analysis results.
[0234] Beacon timing equipment uses a heartbeat mechanism to protect skiers. Ski equipment periodically sends short-range communication mode beacons carrying device ID location information. After receiving the beacon, the multi-mode gateway sends a beacon response and sends the beacon content to the server. In addition to the location information carried in the beacon, the server can also roughly determine the location of the snowshoe equipment through the multi-mode gateway that received the beacon. If the ski equipment does not receive a beacon response, it sends a beacon in long communication mode. If it still does not receive a response, a warning sound will be emitted locally to inform the skier that the device communication is abnormal and to contact the ski resort service staff for inspection as soon as possible. The server maintains a beacon timer for each snowshoe device. Each time a device sends a beacon, the timer is cleared. If no beacon is received for a long time, it means that the device has failed or the skier has skied out of the coverage of the multi-mode base station. At this time, the rescue process will also be initiated.
[0235] The communication network services provided by the multi-mode gateway include, but are not limited to, independent access and management services for different network communications, such as satellite links, cellular network links, RFID gateways, LTE core networks, WLAN gateways, and LoRa core networks. This communication network service dynamically adjusts any communication parameter based on industry requirements and / or physical location. For example, physical communication parameters such as source coding, channel coding, modulation model, signal time slots, and transmit power can be adjusted. It also features flexible scheduling and scalable wireless link access and management technology, enabling remote device control, upgrades, parameter reading / modification, and management. It also supports link self-healing, providing highly utilized, stable, and easily recoverable professional wireless network bearer services.
[0236] If a dangerous situation occurs, the sensing terminal can automatically adjust its sensing strategy, such as increasing the sampling frequency or progress, and can also request changes to communication parameters and strategies from higher-level devices, thereby achieving higher-speed, more reliable, and more appropriate transmission through multi-mode communication. Dynamically adjustable communication parameters include carrier frequency, carrier bandwidth, modulation method, channel coding, transmit power, and receive sensitivity.
[0237] The dynamic adjustment method for communication parameters can be determined based on the data characteristics of the sensor group used in the smart ski equipment. For example, after the perception terminal makes a decision based on the perception data, the perception terminal's perception strategy, communication parameters, and / or network transmission rules can be adjusted based on the decision content. For example, when the decision content indicates that a specified condition has been met, such as when a dangerous situation occurs, the perception terminal can automatically adjust the communication parameters, such as increasing the sampling frequency or sampling progress, and can also request changes to the communication parameters and communication strategy from the superior device.
[0238] Beacon timing equipment is installed in a server, which performs timing operations for beacons received by multiple multimode gateways and provides warnings upon timeout. In another embodiment, the beacon timing equipment is installed in a multimode gateway. Multiple multimode gateways are aggregated into a network in an ad hoc manner, and beacons from the same ski equipment are aggregated or shared within this network. This embodiment reduces server computing requirements. Upon receiving an alert, the skier's location can be roughly determined based on the coverage area of the multimode gateway that received the beacon, notifying rescue personnel to conduct on-site rescue operations at the corresponding location until the skier is out of danger.
[0239] On the server side, the security protection system has its own software architecture, consisting of a device layer, a data layer, an application layer, and a presentation layer. The device layer manages the multimode gateway and the ski equipment connected to the security protection system; the data layer manages and processes incoming static and dynamic data in a categorized manner; the application layer provides multiple pre-configured applications for users to access and implement various functions; and the presentation layer displays the processing results of the application layer.
[0240] For example, the application layer provides a visual display of device locations. The display layer can display the location distribution of each device on an electronic map. To overcome the excessive volume of location data from a large number of users, discrete location information must be interpolated. This interpolation method involves determining the curve type and curvature based on the straight-line distance between two adjacent location information and the time interval between the two location information. A simulated curve is generated based on the determined curve type and curvature, and the simulated curve is used as the path between the two location information.
[0241] For example, the application layer provides a task allocation algorithm for rescue personnel when an alarm occurs. At this time, the display layer can show the optimal probability of rescue personnel performing the rescue task. Multiple applications in the application layer can be constructed in a middle platform manner, which provides preset applications such as data aggregation and integration, purification and processing, visualization and comprehensive application to improve the level of data management. The applications in the application layer include data encryption applications and decryption applications to improve the security of data transmission. The encryption key is determined according to the data label to facilitate the classification and processing of sensor data. The data label can be a label that has an identification function for the sensor data, such as the sensor ID that generated the data, the data quality evaluation result, etc. The display layer provides users with personalized choices in the form of menus or option boxes, and displays the corresponding data according to the display parameters selected by the user.
[0242] In real-world scenarios, a server located in the cloud collects multimodal big data from all snowshoe devices, trains it in an intelligent computing center, and then generates a large AI model for skiing guidance, safety tips, and parameter analysis. This model is then delivered to the user with precise location, direction, and target. Because cloud computing suffers from transmission and computational delays, resulting in limited real-time performance, some computing tasks can be performed on the snowshoe itself, integrating cloud and edge computing. Data processing and fusion can also be performed on the multimode gateway to achieve better data response.
[0243] In one embodiment, the security protection module further includes:
[0244] A communication module unit, wherein the communication module is equipped with short-distance communication and long-distance communication. The short-distance communication is used for communication between skiing equipment and electronic equipment, and the long-distance communication is used for communication between skiing equipment and a multi-mode gateway.
[0245] In this embodiment, in order to adapt to the communication needs in different scenarios, the communication module has two standards: short-distance communication and long-distance communication. Short-distance communication is used for communication between ski equipment and electronic devices carried by skiers, such as vital signs watches or smart wearable devices, and long-distance communication is used for communication between smart ski equipment and multi-mode gateways. The multi-mode gateway establishes communication channels with both ski equipment and electronic devices, and the two serve as primary and backup communication channels for each other. When an abnormal situation occurs, if the communication between the ski equipment and the multi-mode gateway is unobstructed, only the ski equipment and the multi-mode gateway can be used to communicate. However, if the communication between the ski equipment and the multi-mode gateway is blocked (such as being stuck in the snow and unable to communicate), the long-distance communication of the electronic device is enabled to send an alarm message to the multi-mode gateway. Preferably, the primary and backup communication links use different communication standards to achieve more robust communication links.
[0246] In some extremely harsh communication environments, the primary and backup communication channels mentioned above may fail. As an alternative, ski equipment and electronic devices can use the human body as a communication medium. This is achieved through human body communication (HBC). This technology uses low-frequency (typically 125 kHz) signals, with one electrode on each wristwatch and snowshoe in contact with the skin. HBC technology is a short-range communication method (also known as near-field communication) that uses the human body as a medium for digital signal transmission.
[0247] In one embodiment, the security protection module further includes:
[0248] The multi-mode positioning unit is used to connect to the skier's ski equipment through the multi-mode gateway to obtain the skier's positioning information.
[0249] In this embodiment, the aforementioned positioning can utilize the Beidou positioning system, which not only provides location information but also features features such as ski area restrictions. The ski equipment has built-in trail maps and electronic fences. When the skier's current position is detected as off-trail, an alarm is sent to prevent the skier from straying off-trail. To further improve positioning accuracy, RTK differential data technology can also be used. RTK data can be broadcast by a multimode gateway, and all devices within the multimode gateway's coverage area can receive this broadcasted RTK data. As shown in Figure 18, in the event of an emergency, Beidou satellites may be unable to properly locate the skier due to antenna obstruction, making it impossible to accurately determine the skier's location. In this case, multimode positioning can provide a backup position. If there are more than three multimode base stations around the device, and the base stations are not collinear, the positioning process is as follows: the device performs ranging operations with each of the three multimode base stations. The three ranging results and signal strengths are aggregated to a server. The server uses the ranging results and the multimode gateway's location to determine the skier's approximate location, while also using signal strength to increase positioning accuracy.
[0250] In one embodiment, the security protection module further includes:
[0251] An abnormality alarm unit, used to determine whether the skier has an abnormality based on the skier's positioning information and communication status;
[0252] The safety protection unit is used to determine the skier's position, issue an early warning and implement protective measures when it is judged that the skier has an abnormality.
[0253] In this embodiment, as shown in Figure 19, the ski equipment periodically (e.g., every 10 seconds) sends a beacon carrying an ID and location information, allowing the multimode gateway to learn the ski equipment's location. If the skier accidentally slips off the slope or gets stuck in the snow, causing communication to become inoperable, the alarm message and location information cannot be sent to the multimode gateway. If the multimode gateway does not receive the ski equipment's beacon for more than a certain period of time (e.g., 20 seconds), it can infer that the skier may have a problem and assign personnel to search for the skier near the multimode gateway where the ski equipment last communicated (plus the last location information sent).
[0254] The snowshoe device connects to the ski poles via short-range wireless communication, collecting sensor data from the poles for centralized analysis. The snowshoe device can connect to a mobile phone via Bluetooth or WiFi, and establish a connection to a server via a mobile gateway. Positioning information and sensor data can be shared between the snowshoe device and the phone. The phone has a dedicated app that collects all of the skier's status data and provides a connection to the server.
[0255] Figure 20 is a schematic diagram of the logic framework of the safety protection system provided by the present disclosure. As shown in Figure 20, the alarms that may be generated by the safety protection system generally come from three aspects, namely, ski equipment, vital sign watch and beacon timing equipment.
[0256] Both the ski equipment and the vital sign watch use their sensors to collect various parameters of the skier's condition. When abnormal vital signs are detected, such as hypothermia, abnormal heart rate, or prolonged inactivity; abnormal posture, such as falling, flipping, excessive acceleration, or inconsistent foot position; or abnormal equipment, such as the skis becoming detached from the boots or the boots falling off, an alarm message is sent to the multimode gateway via long-distance communication, along with the current location information. If Beidou positioning is not enabled, it is immediately enabled and, after acquiring the location information, the location information is retransmitted to the multimode gateway. Upon receiving the alarm message, the multimode gateway sends it to the server, which then dispatches the nearest rescue personnel to the scene based on the alarm's location information. Furthermore, when abnormal posture is detected, the ski equipment initiates an emergency braking measure, using a parachute placed on the skishoes or the skier's backpack to slow the skier's speed. The emergency braking measure is triggered based on whether the skier's speed exceeds a preset speed threshold, exceeds a safe range, or is manually triggered by the skier, further protecting the skier's safety.
[0257] Other components include an audio input device, such as a microphone, for capturing external sounds; an audio output device, such as a speaker, for outputting audio information; and a light prompt device, such as a flashlight, for outputting light information. Both audio and flash alarms help rescuers find skiers, especially at night.
[0258] In one embodiment, the ski equipment includes a sensor group for acquiring skiing information data of the skier and transmitting it to the equipment management module.
[0259] In this embodiment, one or more of the following sensors are included:
[0260] pressure sensors to detect the force applied by the skier to the ski equipment;
[0261] A posture sensor is used to detect the posture information of the ski equipment and the movement posture of the skier when the ski equipment is in use;
[0262] Contact sensors, used to detect contact between the skier and the ski equipment;
[0263] distance sensors for detecting the relative positions of the separate parts of the ski equipment;
[0264] Body temperature sensor, used to detect the skier's body temperature data;
[0265] Heart rate sensor, used to detect the skier's heart rate data;
[0266] A position sensor for detecting the current position of the ski equipment;
[0267] Angle sensor, used to detect the change in angle between the skier and the ski equipment during skiing;
[0268] An image sensor for acquiring images during skiing;
[0269] Strain sensors, used to obtain the deformation state of ski equipment;
[0270] Temperature sensor, used to obtain temperature information of ski equipment;
[0271] Speed sensor, used to obtain the linear speed and angular speed of the ski equipment;
[0272] Humidity sensor, used to obtain the humidity status inside the ski equipment;
[0273] When using a sensor set for smart skiing equipment, data fusion technology can be used to improve the relevance of sensor data collected by multiple sensors. This technology primarily includes the following methods: When the number of sensor data samples is insufficient, data augmentation can be used to expand the data. One data augmentation method includes extracting a feature matrix from existing data samples and deriving several basic matrices based on the multiple feature matrices; determining multiple augmentation parameters during the augmentation process using a generated random sequence; performing operations on the basic matrix based on the multiple augmentation parameters to obtain a processed feature matrix; and generating augmented data samples based on the processed feature matrix. This method implements the augmentation operation on the data samples.
[0274] Data fusion involves the following steps: extracting features from selected categories of sensor data using a first model and fusing the extracted features using techniques such as splicing, segmentation, and encoding. The spliced features are then normalized or transformed using AI, and the data is further identified based on multiple dimensions to improve the sensor data fusion effect. The fused data features are then processed using an attention mechanism. In addition to the aforementioned sensor data fusion, research is also provided on the reliability and inter-correlations of sensor data. For example, the sensor's health status is first identified, which is divided into offline and online identification. Offline identification includes determining if a sensor's health status is faulty due to calibration failure, power outage, or communication failure. Online identification involves determining whether the sensor data is consistent with the overall situation based on real-time state parameters and posture monitoring data during the skiing process, thereby determining whether the sensor is faulty.
[0275] The correlation between sensors is determined as follows. Step 1: Based on the spatial distribution information and data type of the sensor group, a spatial coordinate model of each sensor's location is established. Step 2: Based on whether the detection data exceeds a preset threshold, the first sensor set exceeding the threshold is determined. Step 3: Based on the first sensor set and the correlation distance threshold, the second sensor set is identified. Step 4: Based on the location of each sensor in the second sensor set, a three-dimensional multi-faceted space is constructed according to the principle of maximizing spatial volume to obtain an effective sensing area. The sensors in the effective sensing area can achieve mutual verification and strong spatial correlation.
[0276] The present invention also provides intelligent skiing equipment, including a self-generating ski board for the intelligent ski equipment, and / or a power generation device for the intelligent ski equipment, and / or a piezoelectric device for the intelligent ski equipment, and / or a movement guidance system for the intelligent ski equipment, and / or a communication system for the intelligent ski equipment. The ski board of the present invention can be equipped with a power component on both the front and rear sides to ensure front-to-back balance. The power component can change its windward orientation as the ski board's direction of motion changes, with the windward blades always facing the wind, ensuring maximum wind exposure, thereby converting wind energy into electrical energy for self-generated electricity. The present invention can also utilize pressure from the bottoms of the skier's feet and the front of their lower legs to repeatedly compress the pressure-generating component, allowing the electrical energy generated by the pressure-generating component to power the electrical components through the charging circuit. The present invention generates a continuous supply of electrical energy through separate power generation, minimizing the impact of the skiing environment on battery performance. In addition, the present invention also uses ski boots and skis as communication terminals to replace mobile phones for communication processing and human body monitoring. Not only that, the present invention also promotes the correct skiing movements of users through AI action guidance, which is conducive to ensuring the user's skiing safety.
[0277] In summary, the ski body of the present invention can be equipped with two power components, one at the front and one at the back, to ensure front-to-back balance. The power components can change their windward orientation as the ski's direction of motion changes, ensuring that the windward blades always face the wind, ensuring maximum wind exposure. This converts wind energy into electricity, generating self-generated electricity. The present invention also utilizes pressure from the skier's feet and the front of their lower legs to repeatedly compress the pressure-generating components, allowing the electricity generated by these components to power the power-consuming components via the charging circuit. This invention generates a continuous supply of electricity through separate power generation, minimizing the impact of the skiing environment on battery performance. Furthermore, the present invention utilizes the ski boots and ski board as communication terminals, replacing mobile phones for communication processing and body monitoring. Furthermore, the present invention promotes correct skiing techniques through AI-guided movement guidance, thereby ensuring skiing safety. Taking skiing as an example, the present invention provides intelligent equipment, a power generation device, a movement guidance method, and a communication system. The intelligent skiing equipment includes a self-generating ski board for the intelligent skiing equipment, and / or a power generation device for the intelligent skiing equipment, and / or a piezoelectric device for the intelligent skiing equipment, and / or a movement guidance system for the intelligent skiing equipment, and / or a communication system for the intelligent skiing equipment. The ski board of the present invention can be equipped with a power component at the front and rear to generate self-generated electricity. The present invention can also generate electricity through pressure. The present invention generates a continuous source of electricity through separate power generation, thereby minimizing the impact of the skiing environment on battery performance.
