Technical Field
[0003] The present invention relates to a power generation device, AI technology and communication system, etc. The following only takes skiing as an example to illustrate the main points of the invention. Background Art
[0004] Skiing is a winter sport that involves sliding on snow using skis or snowboards. Skiing can be done on flat ground, on a hillside, or at a dedicated ski resort. Skiers usually wear special ski boots that can be fixed to the skis to better control the direction and speed of the slide. Skiing can be divided into many types, such as Alpine Skiing: It is done on steep slopes, usually by taking a cable car to the top of the mountain and then sliding down along a marked path; Cross-country Skiing: It is done on relatively flat terrain, which can be natural terrain or artificial ski trails; Freestyle Skiing: It is done on a special site and includes jumps, flips and other tricks; Snowboarding: It is similar to skiing, but uses a single board instead of a double board, and the movements and techniques are also different; Ski Jumping: Jumping from a high platform, flying a distance in the air and landing; Nordic Combined (Biathlon): It combines cross-country skiing and shooting, and athletes need to shoot 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 good way to enjoy the winter scenery and experience excitement.
[0005] Smart wearable devices are a type of intelligent terminals that integrate sensors, wireless communications, multimedia and other technologies. They can be worn directly on the human body and realize intelligent interaction of information through built-in sensors and integrated chips. The main types of smart wearable devices currently include: AR / VR / MR head-mounted devices: These devices provide users with an immersive visual experience through augmented reality (AR), virtual reality (VR) or mixed reality (MR) technology. Smart audio glasses: Glasses that combine audio playback functions and fashionable designs, allowing you to listen to music or make calls without obstructing your vision. Bluetooth headsets: Wirelessly connected headsets that may have functions such as health monitoring in addition to making calls and listening to music. Smart watches: They have multiple functions other than time display, such as health monitoring, message reminders, and answering calls. Health monitoring devices: Such as heart rate monitors, sleep trackers, etc., used to record and analyze the user's health status. Children's smart watches: Designed specifically for children, they usually have functions such as positioning, calling and emergency assistance. As a product of the mobile Internet era, smart wearable devices are gradually becoming an indispensable part of people's lives. They not only improve the convenience of life, but are 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] With the development of the market, the forms of smart wearable devices will become more diversified, 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. The present invention aims to expand smart wearable devices in the field of skiing.
[0007] The design requirements of smart facilities on skiing equipment are relatively demanding. The specific temperature and weather conditions during skiing vary depending on the geographical location and season. In some high-altitude areas or in winter, the temperature may be very low, even reaching dozens of degrees below zero, and there may be severe weather such as strong winds and blizzards. Under such conditions, skiers need to wear heavy ski suits and goggles to protect themselves from the cold and snow. However, for skiers, the heat in the feet of the body cannot keep up with the speed of heat dissipation, and it is easy to get cold feet when wearing ski boots.
[0008] Smart device batteries become less efficient in low temperatures. This is because the chemical reactions inside the battery slow down in cold conditions, causing the battery's ability to deliver power to decrease. This can cause the smart device's battery to drain faster, or in extreme cases, the device may shut down because it cannot deliver power even if the battery is fully charged.
[0009] LCD screens may have a slow response problem at low temperatures. This is because the fluidity of the liquid crystal material deteriorates at low temperatures, affecting the speed at which pixels change, causing problems with touch screen functions or display updates.
[0010] Some smart devices, such as mobile phones, may also fail in cold environments due to embrittlement of materials or weakening of lubricant effects, which may cause the phone to not work properly and cause it to shut down automatically. It is very inconvenient to use mobile phones in ski areas.
[0011] In addition, good skiing areas are often remote and may have no communication signals. In addition, ski resorts are relatively empty, which poses certain safety risks when skiing.
[0012] Therefore the prior art still needs to be improved and enhanced. Summary of the invention

After the wind-incoming blades 210 are pushed and rotated by wind resistance, the inner ratchet 230 is driven to rotate. Specifically, a pawl 240 is provided on the flywheel 220. The pawl 240 cooperates with the inner ratchet 230. The inner ratchet 230 pushes the pawl 240 in one direction to drive the flywheel 220 to rotate. The flywheel 220 is connected to the generator 250 through a rotating shaft to drive the generator 250 to work. 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 is moving, 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 beneficial to ensuring the transmission and reception of information.
[0130] Furthermore, in the self-generating ski board of the intelligent ski equipment provided by the present invention, the diameter of the windward blade 210 on the windward side is greater than the diameter of the flywheel 220 and / or the generator 250. Generally, the diameter of the windward blade 210 at the front end is very large, greater than the diameter of the windward blade 210 at the rear end. Furthermore, in the self-generating ski board of the intelligent ski equipment provided by the present invention, the windward blade 210 is a turbo fan.
[0131] Furthermore, in the self-powered ski board of the intelligent ski equipment provided by the present invention, the power components 200 are two, namely the front power component 200 and the rear power component 200, the front power component 200 is located at the front end of the ski board body 100, and the rear power component 200 is located at the rear end of the ski board body 100. This is conducive to maintaining the balance of the ski board during exercise. In particular, in the self-powered ski board of the intelligent ski equipment provided by the present invention, on the side where the windward surface is located, the diameter of the windward blade 210 of the rear power component 200 is greater than the diameter of the windward blade 210 of the front power component 200. This can increase the amount of wind received by the rear power component 200.
[0132] Furthermore, in the self-powered ski board of the smart ski equipment provided by the present invention, the power component 200 is connected to the ski board body 100 so as to be rotatable left and right through the rotating column 300. Furthermore, in the self-powered ski board of the smart ski equipment provided by the present invention, in another embodiment, the power component 200 is ball-hinged on the ski board body 100, so that more rotation angles can be achieved.
[0133] 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, and the wind-incoming blades 210, the flywheel 220 and the generator 250 are all arranged in the housing 260. Further, in the self-generating ski board of the intelligent ski equipment provided by the present invention, a wind collecting channel 270 is arranged in the housing 260, and the wind-incoming blades 210 are arranged in the wind collecting channel 270. There are two wind-incoming blades 210, which are respectively arranged at the front end and the rear end of the wind collecting channel 270. There are two flywheels 220, which are respectively connected to the two wind-incoming blades 210, and the generator 250 adopts a double-headed generator 250. The connection structure between the wind-incoming blades 210 at the rear end and the generator 250 is the same as the connection structure of the wind-incoming blades 210 at the front end. The present invention adopts two wind-incoming blades 210, and the front one is larger than the rear one. With the wind collecting channel 270, the wind force gathered at the rear end is also enhanced, thereby further increasing the self-generating efficiency.
[0134] Furthermore, the ski board body is provided with a solar top panel 280 for converting light energy into electric energy during skiing. Preferably, the solar top panel 280 is a flexible thin-film solar panel, which has the advantages of being lighter and being able to bend with the board body without being damaged. Furthermore, the ski board is also provided with an energy storage component, which is electrically connected to the electric component and stores the electric energy generated by the electric component; the ski board body is provided with a solar top panel for converting light energy into electric energy during skiing, which is electrically connected to the solar top panel and stores the electric energy generated by the solar top panel.
[0135] Furthermore, it also includes a heating component, which is located at the location of the ski boots on the ski body, and the heating component is electrically connected to the energy storage component. The electric energy generated by the power component is used by the heating component to provide heat for the ski boots to keep warm or the working environment of the electronic device. Further, it also includes a temperature control component, which is electrically connected to the heating component. Further, it also includes a temperature sensing component, which is electrically connected to the heating component. Further, the heating component is a PTC heater; the PTC heater is composed of a plurality of independent PTC plates, which can be controlled by the temperature control component to heat the ski equipment more intelligently. Further, the temperature control component includes an online detection module and an offline detection module, which are respectively applied to online detection scenarios and offline detection scenarios; wherein 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 measurement temperature according to 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 after measurement, and obtain the corresponding temperature value as the measurement temperature according to the resistance value. Further, the target temperature of the temperature control component is a fixed value or calculated according to the temperature control logic. Further, the temperature control logic includes: obtaining meteorological parameters of the scene where the ski equipment is located, the meteorological parameters include data such as temperature, wind speed, wind direction, and air pressure, and determining the target temperature of the heating component according to the meteorological parameters and a preset temperature determination algorithm; or, the temperature control logic includes: the online detection module can implement the temperature control logic of the offline detection module on the server side, and can adjust the target temperature according to the temperature preference of the skier.
[0136] like Figure 6.1 and Figure 7 As shown, the power generation device for intelligent skiing equipment provided by the present invention includes a pressure power generation component 1 for collecting electrical energy from the pressure applied by the skier from the bottoms of the skier's feet and the front side of the lower calves during skiing, and a charging circuit for delivering electrical energy to electrical components, and the pressure power generation component 1 is electrically connected to the charging circuit.
[0137] It is understandable that during skiing, the skier will use the basic skiing movements to apply two pressures to the snowshoes. One is squatting with the whole body, the whole body exerts force through the thighs, calves, and feet, and finally the feet exert force downward to act on the bottom of the snowshoes. The other is leaning forward, the whole body exerts force through the front side of the lower leg (upper ankle), and finally the front side of the lower leg (upper ankle) exerts force to push against the inner side of the tongue of the snowshoe. Therefore, the pressure from the bottom of the skier's feet and the front side of the lower leg can press the pressure power generation component 1 to generate electricity, so that the electrical energy is used to power the electrical components through the charging circuit.
[0138] Compared with the prior art, the present application can utilize the skier's own gravity to generate electricity during skiing using the pressure power generation component 1, thereby generating electrical energy. This process requires additional charging of the ski boots 9 to power the electrical components on the ski boots 9.
[0139] In one embodiment, if Figure 6.1-6.2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the ski equipment is a ski, and the pressure power generation component 1 includes a covering part 2 fixed on the ski equipment, and the ski boots 9 on the ski equipment are located in the covering part 2. Pressure power generation components 3 are provided on the ski equipment and below the ski boots 9, and on the inner side of the covering part 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 part 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.
[0140] 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 are able to slide upward and downward relative to the covering 2 , the pressing member 4 always maintains contact with the pressure generator 3 .
[0141] 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, and the above-mentioned two pressures respectively press the pressure generator 3 repeatedly, thereby causing the pressure generator 3 to generate electrical energy.
[0142] Furthermore, the pressure generator 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.
[0143] 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 the present application, and will not be described in detail here.
[0144] Furthermore, a slide rail 6 is provided on the inner side wall of the covering member 2 and is slidably arranged with the clamping member on the outer side of the snowboard.
[0145] Preferably, a compression spring 7 is provided in the slide rail 6, one end of the compression spring 7 is fixed to the slide rail 6, and the other end of the compression spring 7 is fixed to the clamp. When a skier is skiing on the snow, since the pressing member 4 is always in contact with the pressure power generation member 3, and under the action of the compression spring 7, the pressing force of the skier on the bottom of the ski boot 9 is constantly changing during the sliding process, and the amplitude of the pressing force of the compression spring 7 can fluctuate greatly, that is, under the action of the compression spring 7, the power generation efficiency of the pressure power generation member 3 is higher.
[0146] Preferably, four slide rails 6 are provided, which are respectively located on the inner side walls of the left and right sides of both ends of the cover 2. It can be understood that the ski boots 9 are provided with clamps around them for sliding with the slide rails 6, which is equivalent to the ski boots 9 being provided with force-bearing parts around them, which can ensure that when the skier is skiing, the ski boots 9 slide up and down relative to the cover 2, and the pressing effect of the pressing member 4 on the pressure generator 3 is better.
[0147] Further, 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.
[0148] It can be understood that, since the front end and the 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 the bottom of the ski boots 9 to be converted into electrical energy, the slide rail 6 is non-vertically arranged for the squeezing force of the pressing piece 4 on the pressure generator 3, so that when the skier slides forward, the squeezing force on the front end and the bottom of the ski boots 9 is converted into the squeezing force of the pressing piece 4 on the pressure generator 3, which can effectively improve the power generation efficiency of the pressure generator 3 and prevent the skier from falling when the ski boots 9 of the skier slide up and down relative to the covering 2.
[0149] 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 skier's lower calf (upper ankle) on the inner side of the tongue of the ski boot 9 during skiing fluctuates less, while the slide rail 6 and the compression spring 7 enable the pressing force exerted by the pressing piece 4 at one end of the tongue of the ski boot 9 on the pressure generator 3 to fluctuate more greatly, that is, the slide rail can increase the pressing amplitude of the pressing piece 4 at one end of the tongue of the ski boot 9 on the pressure generator 3, thereby improving the power generation efficiency of the pressure generator 3.
[0150] Furthermore, since the slide rail 6 is not vertically arranged, the prerequisite for the ski boots 9 to slide relative to the cover 2 is that a gap is provided between the inner wall of the cover 2 and the ski boots 9, and the gap can provide the space required for the ski boots 9 to slide relative to the cover 2.
[0151] Furthermore, a sealing member 8 is provided between the upper end of the covering member 2 and the ski boot 9. It is understandable that due to the existence of the gap between the covering member 2 and the ski boot 9, dirt and gravel may easily enter the gap, thereby damaging the ski boot 9, and the sealing member 8 may be used to prevent dirt and gravel from entering the gap, thereby ensuring that the ski boot 9 can be used normally.
[0152] 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.
[0153] Further, the pressing member 4 comprises a pressing body and a pressing head arranged in contact with the pressure power generating member, and the pressing head and the pressing body are connected via an elastic member. Further, a power generating device is connected to the side of the pressing body. Further, as Figure 6.2As shown, a bar gear 910 is provided on the side of the pressing body, and the power generation device includes a speed change 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 with the transmission shaft 911, so as to mesh with the first bevel gear 914, and the second bevel gear 915 is meshed with the speed change gear set, and the speed change gear set is meshed with the first flywheel 912. The first flywheel 912 is meshed with an outer gear, a row of teeth 916 is provided on the inner side of the first flywheel 912, a ratchet 917 is provided on the second flywheel 913, the second flywheel 913 is located on the inner side of the first flywheel 912, the first flywheel 912 is fixed to the rotating shaft of the power generating element, the second flywheel 913 is not fixed to the first flywheel 912, and the ratchet 917 is meshed with the row of teeth 916, when the second flywheel 913 rotates counterclockwise, the ratchet 917 acts on the row of teeth 916 to drive the first flywheel 912 to rotate. When the second flywheel 913 stops or rotates clockwise, the ratchet 917 cannot mesh with the row of teeth 916, so it does not affect the first flywheel 912 to keep rotating counterclockwise.
[0154] Furthermore, the rotation of the first flywheel 912 can drive the generator to generate electricity. For example, a magnet is installed on the inner wall of the first flywheel 912 and rotates simultaneously with the flywheel. A coil is installed statically inside the flywheel. The rotation of the magnet can produce the effect of the coil cutting the magnetic field lines, thereby generating electrical energy. Other electromagnetic power generation mechanisms with similar principles can also be used, which are not limited here.
[0155] 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.
[0156] It can be understood that the first bevel gear 914 is driven to rotate by the bar gear 910 on the pressing piece, 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 piece 4 is repeatedly pressed by external force, the generator can continue to generate electricity.
[0157] As another implementation, the first bevel gear 914 may also use a spur gear, in which 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.
[0158] It should be noted that the transmission mechanism can make the flywheel 912 rotate multiple times by moving the bar gear 910 a very small distance. In order to achieve the best power generation efficiency, different numbers of gear sets or speed transmission mechanisms with equivalent effects can be used between the flywheel 912 and the bar gear 910, and each gear set can optionally use different speed ratios, as long as the final driving direction of the multiple gear sets can make the first flywheel 912 rotate counterclockwise. Of course, if it is not possible to ensure that the first flywheel 912 is driven to rotate counterclockwise, the directions of the ratchet 917 and the row of teeth 916 can be changed to make the first flywheel 912 rotate clockwise.
[0159] It should be noted that the pressing member can be repeatedly pressed by the elastic member between the pressing head and the pressing body.
[0160] like Figure 11.1 , Figure 11.2 , Fig.12 and Fig.13 As shown, the present invention also provides a power generation device applied to smart skiing equipment, including an arc-shaped pressure power generation sheet, wherein the arc-shaped pressure power generation sheet includes a metal substrate 21, a piezoelectric ceramic 22 and an insulating tape 23, wherein 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.
[0161] The metal substrate 21 is used to support the piezoelectric ceramics 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 ceramics 22 deform with the metal substrate 21 and generate 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.
[0162] The piezoelectric device applied to the intelligent skiing equipment of the present invention comprises a plurality of arc-shaped pressure power generation sheets, and the plurality of arc-shaped pressure power generation sheets are stacked layer by layer to form a pressure power generation group.
[0163] 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.
[0164] A rigid support member 25 is fixed at 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 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, and the power generation sheet generates electrical energy during the two processes of deformation and recovery.
[0165] As another implementation scheme, 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.
[0166] Four pressure generating groups 24 are installed on the inner wall of the snowshoes in four directions, front, back, left, and right. In this way, no matter in which direction the skier applies pressure to the snowshoes, electricity can be generated and collected. The electrodes between the pressure generating groups 24 are connected in series through wires, and finally only one electrode outputs. Since the deformation / bending distance of the pressure generating group 24 is very small, it will not affect the skiing action. The pressure generating group 24 generates electricity by the natural, repeated pressure and stepping pressure on the snowshoes when the skier makes a move, and the skier does not need to deliberately and subjectively apply pressure to the snowshoes. The maximum efficiency of electrical energy output is achieved by changing the number of layers and shape of the multi-layer arc-shaped pressure generating sheets, the toughness of a single generating sheet, the thickness and material of the piezoelectric ceramic 22, etc.
[0167] As another embodiment, the output electrodes of multiple pressure power generation groups 24 are connected in parallel to the output electrodes. As another embodiment, the output electrodes of multiple pressure power generation groups 24 are connected in parallel after passing through the rectifier circuit. At this time, when only a few power generation groups generate electricity, the other power generation groups that are not generating electricity will not consume additional electricity. As another embodiment, the same multi-layer power generation sheet solution can also be used between the sole of the snowshoe and the snowboard.
[0168] In order to improve the safety of skiing for users, the present invention also provides an action guidance method for intelligent skiing equipment.
[0169] See also Fig.14 , Fig.14 Flow chart of an embodiment of the method for guiding the movement of intelligent skiing equipment provided by the present invention. Fig.14 As shown, the method comprises the following steps:
[0170] S101, obtaining skiing information data of a skier;
[0171] S102, inputting the skiing information data into a pre-trained AI action recognition model, and the AI action recognition model outputting the skier's skiing action according to the skiing information data;
[0172] S103, comparing the skiing action with the preset standard action for the scene, and guiding the skier's action according to the preset standard action for the scene.
[0173] In this embodiment, the skiing information data of the skier is obtained, and the skiing information data is input into a pre-trained AI action recognition model. The AI action recognition model can be obtained after training using various deep learning models such as CNN, RNN, GAN, LSTM, and attention mechanism. The AI action recognition model outputs the skier's skiing action based on the skiing information data, compares the skier's skiing action with the standard action in the scene, and reminds the skier of the action according to the preset standard action of the scene. The snowshoe equipment is connected to the ski pole through short-range wireless communication, and the sensors sampled by the ski pole are collected and analyzed centrally, and action guidance instructions are sent to the skier through the ski pole to improve the convenience of guiding skiing actions.
[0174] In one embodiment, the skiing information data includes:
[0175] skiing videos and / or skiing images captured by camera equipment on ski equipment;
[0176] Ski pole movements acquired through sensors placed on the ski equipment;
[0177] The skiing posture of the skier is obtained by the posture sensor installed on the ski equipment.
[0178] In this embodiment, the skiing information data includes skiing videos and / or skiing images of the skier obtained by one or more cameras installed on the ski equipment; ski pole movements obtained by sensors installed on the ski equipment; and the skiing posture of the skier obtained by posture sensors installed on the ski equipment.
[0179] Furthermore, wide-angle cameras are installed at the head and tail of the skis in the ski equipment. The cameras are installed at a certain angle upward. 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. Depth camera sampling is more accurate for input data to 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 sensors through the AI algorithm to calculate the skier's posture, movement and other information, and accurately identify the skiing movements.
[0180] In one embodiment, step S102 includes:
[0181] The AI action recognition model recognizes several local postures of the skier based on the skiing information data;
[0182] constructing the overall posture of the skier according to the plurality of local postures;
[0183] The skiing action of the skier is outputted through the overall posture.
[0184] In this embodiment, the AI action recognition model identifies several local postures of the skier based on the input skiing information data, constructs the overall posture of the skier based on the identified local postures, and obtains the skiing action of the skier based on the overall posture of the skier and the input data that does not belong to the posture parameters. In addition, the AI action recognition model analyzes the skier's skiing posture and action in conjunction with the posture sensor, thereby improving the accuracy of identifying skiing actions.
[0185] In one embodiment, the scene preset standard action is obtained by the following steps:
[0186] Obtain a target video recording skiing movements;
[0187] 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.
[0188] In this embodiment, the AI action recognition model is constructed based on the self-attention mechanism, which is used to realize a skiing action recognition based on the self-attention mechanism. By obtaining a skiing video recording skiing actions, the target video is input into a pre-trained deep learning model based on the self-attention mechanism to obtain the standard action of the skier in the skiing video, wherein the query matrix, key value matrix and value matrix in the deep learning model of the self-attention mechanism need to be determined by learning. A vector matrix is extracted from the target video as input, and the vector matrix is multiplied with the query matrix, key value matrix and value matrix respectively to obtain the corresponding result matrix, and then the query matrix i-th row and the result matrix corresponding to the association matrix are multiplied, and the eigenvalue is obtained by multiplying the value matrix of the vector matrix after the activation function, and the corresponding standard action of the skier is obtained based on the eigenvalue. The deep learning model is used to characterize the corresponding relationship between the video recording the skiing process of the skier and the standard action of the skier. The skiing action recognition method based on the self-attention mechanism of this method has fast detection speed and high accuracy.
[0189] In one embodiment, before step S103, the following steps are included:
[0190] Get the ski trail parameter information of the ski scene;
[0191] Determine standard actions corresponding to a number of snow track positions according to the snow track parameter information;
[0192] The optimal posture of the ski equipment is determined according to the ski track parameters and the skiing action of the skier.
[0193] In this embodiment, the posture solution is based on the fusion of multiple data from the posture sensor. Since a skiing action has different postures, the fuzzy control algorithm can be used to map quantitative posture data to skiing actions to avoid the technical problem of inaccurate recognition caused by the fluctuation of posture data. The action guidance method also includes the determination of the standard skiing action, which determines the standard action corresponding to several positions according to the snow track parameters, and includes the following two determination methods. One scheme is based on big data technology, and the skiing trajectory and posture control corresponding to the fastest speed on the current snow track are obtained as the standard action on the snow track. Another scheme is to determine the skiing trajectory based on the snow track parameters, and determine the action parameters of each track segment according to the parameters of the skiing trajectory; and determine the standard action based on the feedback of executing the action parameters. And determine the best posture of the skiing equipment according to the snow track parameters and the skier's control action. For example, the current state parameters and force conditions of the skiing equipment are obtained, the expected action of the skier is determined according to the force conditions, and the best front edge angle or rear edge angle is determined according to the expected action, the current speed and the current position slope.
[0194] Another embodiment of the present invention also provides an action guidance device for intelligent skiing equipment, such as Fig.15 As shown, the device comprises:
[0195] A data acquisition module 11 is used to acquire skiing information data of a skier;
[0196] A motion recognition module 12, used for inputting the skiing information data into a pre-trained AI motion recognition model, and the AI motion recognition model outputs the skiing motion of the skier according to the skiing information data;
[0197] 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.
[0198] The module referred to in the present invention refers to a series of computer program instruction segments that can perform specific functions, which are more suitable for the execution process of the action guidance method for intelligent skiing equipment than programs. For the specific implementation methods of each module, please refer to the corresponding method embodiments above, which will not be repeated here.

[0207] In order to replace a mobile phone to realize communication-related functions, the present invention provides a communication system for smart skiing equipment, comprising:
[0208] Through technologies such as eSIM, all functions of the mobile phone can be automatically transferred to the snowshoe before the phone stops working, or the transfer can be actively operated manually.
[0209] An equipment management module, used for connecting to the skiing equipment of the skier and obtaining the skiing information data of the skier through the skiing equipment, wherein the skiing equipment includes skiing equipment and electronic equipment;
[0210] The safety protection module is used to receive the skiing information data of the skier transmitted by the equipment management module, and judge whether the skier is safe according to the skiing information data.
[0211] In this embodiment, the equipment management module is connected to all skiing equipment of the skier, and the skiing equipment includes skiing equipment and electronic devices, wherein the electronic devices are smart ski poles, vital sign watches, smart wearable devices or mobile phones, wherein the wearable devices include smart helmets, smart ski suits, smart gloves, and smart glasses. Skiing equipment includes ski boots and skis. The skiing information data of the skier is obtained through the skiing equipment of the skier, and the equipment management module transmits the skiing information data to the safety protection module, and the safety protection module determines whether the skier is safe based on the skiing information data.
[0212] Since it is not suitable to carry other equipment during skiing, or it is inconvenient to use mobile phones at low temperatures, it is possible to integrate some functions of smart phones into skiing equipment such as smart helmets or smart ski suits. By placing a display screen on the front side of the snowboard or on the front mirror of the helmet, the communication needs in skiing can be met. Specifically, eSIM or other technical solutions can be used to transfer the relevant functions on the mobile phone to skiing equipment such as snowshoes, and the relevant functions of the mobile phone can be displayed on the display screen of the skiing equipment, so that the skiing equipment can replace the mobile phone for communication. Simple operations can be performed through actions, such as tapping the helmet to answer or hang up the phone; or complex operations can be performed through voice. Based on the demand for VR technology in skiing, smart ski goggles can support high-definition photo and video functions, and at a certain position inside the lens of the smart snow goggles, simple data related to skiing can be displayed, such as: timing, slope, wind direction, wind speed, temperature, speed, weather, terrain, etc.
[0213] In one embodiment, the equipment management module establishes a connection with the ski equipment in the following manner:
[0214] The communication link with the skiing equipment is a first communication channel, and the communication link with the electronic equipment is a second communication channel;
[0215] 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.
[0216] In this embodiment, the communication link between the skiing equipment and the multi-mode gateway is the first communication channel, and the communication link between the electronic device carried by the skier and the multi-mode gateway is the second communication channel. The first communication channel and the second communication channel are mutually primary and backup to reduce the probability of communication interruption. There is a communication interaction link between the electronic device and the skiing equipment. Fig.17 As shown, the Vital Signs Watch has a variety of built-in sensors. For example, the body temperature sensor detects the wearer's body temperature at the wrist, typically using a contact temperature sensor and an infrared temperature sensor; the heart rate sensor obtains the user's heart rate through the PPG method; the posture sensor can obtain the wearer's inclination, acceleration, angular velocity, direction of movement, etc. The Vital Signs Watch has a communication module to facilitate its realization of the aforementioned electronic equipment's main and standby communication, human body communication and many other functions. The Vital Signs Watch also has an SOS button. When the user needs emergency help, he can press the SOS button, and then the communication module will send a distress message to the multi-mode gateway.
[0217] In some embodiments, a smart helmet is also provided, which includes a helmet body and a sensor group for smart skiing equipment installed on the helmet body. The installation method and installation position can be adopted as follows, and the sensors in the sensor group are installed through a plurality of installation holes or installation slots. The helmet body is also provided with connection components with other electronic devices, for example: a mechanical mechanism and communication contacts for installing smart snow goggles, so as to realize communication connection and data sharing with smart snow goggles.
[0218] Since it is not suitable to carry other equipment during skiing, or it is not convenient to use mobile phones when the temperature is low, it is possible to integrate some functions of smart phones into smart helmets or smart ski suits, and place a display screen on the front side of the snowboard or on the front mirror of the helmet to meet the communication needs during skiing. By extracting the information of the mobile phone and displaying it on the screen of the device, some functions of the smart phone are integrated. Simple operations are performed through actions, such as tapping the helmet to answer or hang up the phone. Complex operations are performed through voice. Based on the demand for VR technology in skiing, smart ski goggles can support high-definition photo and video functions. At the same time, a certain position inside the lens of the smart snow goggles can display simple data related to skiing, such as: timing, slope, wind direction, wind speed, temperature, speed, weather, terrain, etc.
[0219] In one embodiment, Fig.21 As shown, the device management module also includes:
[0220] A temperature control unit is used to monitor the temperature of the ski equipment and heat the ski equipment.
[0221] In this embodiment, the heating system applied to the intelligent ski equipment includes: a power supply component, a temperature control component and a heating unit. The ski equipment includes snowshoes, the heating component is arranged on the snowshoes and used to heat the snowshoes, the power supply component is used to supply power to the heating component, and the temperature control component is used to adjust the power of the heating component to heat the snowshoes more intelligently.
[0222] Preferably, the power supply component is a low-temperature rechargeable battery; the heating component is preferably a PTC heater; preferably, the PTC heater is composed of a plurality of independent PTC plates, which can be controlled by the temperature control component to heat the ski equipment more intelligently. Among them, the power supply component is preferably a low-temperature rechargeable battery, and further, the power supply component comes from the aforementioned power generation device applied to the intelligent ski equipment; the heating component is preferably a PTC heater.
[0223] Preferably, the PTC heater is composed of a plurality of independent PTC plates, which can be controlled by the 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 respectively used in online detection scenarios and offline detection scenarios. 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 measurement temperature according to 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 measurement temperature according to the resistance value. The target temperature of the temperature control component can be a fixed value, or it can be calculated according to the temperature control logic.
[0224] Preferably, the temperature control logic includes: obtaining meteorological parameters of the scene where the ski equipment is located, the meteorological parameters including temperature, wind speed, wind direction, air pressure and other data, and determining the target temperature of the heating component according to the meteorological parameters and a preset temperature determination algorithm. This solves the problem of poor adaptability when using the set target temperature for control, and can improve the comfort of skiers.
[0225] 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 can adjust the target temperature according to the temperature preference of the skier. This method integrates big data technology into the temperature control logic of the offline detection module, which is more in line with the skier's comfortable temperature feeling.
[0226] The contact electrodes can be used to detect whether the snowboard and snowshoes are connected. The temperature control component provides functions such as heating control and temperature feedback. PTC heating is used to convert electrical energy into thermal energy. The heating control and temperature feedback circuits are used to control the PTC heater to heat the snowshoes. The heating temperature is controlled by temperature detection in a closed loop. The temperature detection can be directly measured by the resistance value of the PTC heater at different temperatures. Compared with using a separate temperature sensor, the direct PTC heater measures the temperature with a larger correlation area and is closer to the true value. It does not require additional leads, and the system is more reliable.
[0227] Temperature detection uses two methods: online detection and offline detection. Specifically, online monitoring refers to measuring the voltage and current flowing through the PTC heater during the heating process, and then calculating the current resistance of the PTC heater through Ohm's law R=U / I, and then obtaining the current temperature from the temperature-resistance curve of the PTC heater through the table lookup method; since the online detection method requires the PTC heater to be powered on for measurement, if the current actual temperature has exceeded the target temperature, the measurement will cause the temperature to rise further. At this time, it is more appropriate to use the offline detection method. The offline detection method connects the PTC heater to the resistance measurement circuit to measure the resistance. Since the current flowing through the resistance measurement circuit is small, almost no excess heat is generated on the PTC heater; typical resistance measurement circuits include the bridge method, the four-phase resistance method, etc.
[0228] At the same time, the snowshoe main board also provides functions such as snowboard detachment detection, position positioning and posture sensing, which are all realized by sensors with corresponding functions in the sensor group applied to smart skiing equipment. The posture sensor can be composed of one or more sensors such as acceleration sensor, angular velocity sensor and electronic compass, which are used to identify the inclination angle, acceleration, angular velocity, movement direction, etc. of the snowshoe, among which the inclination angle can be used to analyze the dangerous situation of the wearer falling or standing upside down. The left and right snowshoes can detect the movement posture respectively, and summarize the detection results through the wireless communication module. The summarized data can be used to analyze the status of snowshoe detachment, abnormal posture of both feet, etc., and generate an alarm. The snowshoe device is connected to the ski pole through short-range wireless communication, and the sensors sampled by the ski pole are collected and analyzed centrally. The snowshoe device can be connected to the mobile phone via Bluetooth or WiFi, and can establish a connection with the server with the help of the mobile phone gateway. The positioning information and sensor data can be shared between the snowshoe device and the mobile phone. The mobile phone has a dedicated App for collecting all the status data of the skier and providing a connection with the server.
[0229] In one embodiment, the security protection module further includes:
[0230] 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.
[0231] The beacon timing equipment unit is used to record the beacon update status of the ski equipment and generate corresponding alarms according to the update status.
[0232] In this embodiment, there are several multi-mode gateways distributed in the venue, and the multi-mode gateway obtains the location information and communication status of the ski equipment as the transmission source according to the analysis of the received signal; and the beacon timing equipment is set in the multi-mode gateway or the server, which is used to record the beacon update status of the ski equipment and generate corresponding alarms based on the beacon update status. The multi-mode gateway is configured to: respond to the beacons in the short-distance mode and the long-distance mode; obtain the location information of the beacon transmission source according to the beacon in the long-distance mode; and analyze the alarm information and voice information in the beacon. The beacon timing equipment is configured to: clear the timing duration of the beacon transmission source after receiving the beacon, and issue a beacon timeout alarm for the beacon transmission source whose timing duration exceeds the preset duration. The received beacon is analyzed, and the distance or position of the transmission source is determined by the analysis result.
[0233] 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 receives the beacon. If the ski equipment does not receive a beacon response, it sends a beacon in the long communication mode. If it still does not receive a response, a warning sound will be issued locally to prompt 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 the beacon is not received for a long time, it means that the device has failed or the skier has slid out of the coverage of the multi-mode base station. At this time, the rescue process will also be initiated.
[0234] The communication network services that the multi-mode gateway can provide include but are not limited to separate 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. The communication network service provides network services that dynamically adjust any communication parameters according to industry requirements and / or physical locations, such as source coding, channel coding, modulation model, signal time slot, transmission power and other physical communication parameters; it can also flexibly schedule and flexibly expand wireless link access and management technology, and can perform functions such as remote control, upgrade, parameter reading / modification, and management of equipment, support link self-healing, and provide high-utilization, strong stability, and easy-to-recover professional wireless network bearer services.
[0235] If a dangerous situation occurs, the sensing terminal can automatically adjust the sensing strategy, such as increasing the sampling frequency, increasing the sampling progress, etc. At the same time, it can request the superior device to change the communication parameters and strategies, so as to obtain higher speed, higher reliability and more suitable transmission in the form of multi-mode communication. Among them, the dynamically adjustable communication parameters include carrier frequency, carrier bandwidth, modulation mode, channel coding, transmission power, receiving sensitivity, etc.
[0236] The dynamic adjustment method in the communication parameters can be determined according to the data characteristics of the sensor group applied to the smart skiing equipment. For example: after the perception terminal makes a decision based on the perception data, the perception strategy, communication parameters and / or network transmission rules of the perception terminal can be adjusted according to the decision content. Exemplarily, when the decision content shows that the specified conditions are met, such as when a dangerous situation occurs, the perception terminal can automatically adjust the communication parameters, such as increasing the sampling frequency, increasing the sampling progress, etc., and can request the superior device to change the communication parameters and communication strategy.
[0237] The beacon timing equipment is set in the server, and the server implements the timing operation and the warning operation after timeout for the beacons received by multiple multi-mode gateways. In another embodiment, the beacon timing equipment is set in the multi-mode gateway, and the multiple multi-mode gateways are aggregated into a network in an ad hoc manner, and the beacons of the same ski equipment are aggregated or shared in the network. This embodiment reduces the computing requirements of the server. After receiving the alarm, the location of the skier can be roughly determined based on the coverage range of the multi-mode gateway that received the beacon, so as to notify the rescue personnel to carry out on-site rescue at the corresponding location until the skier is out of danger.
[0238] On the server side, the security protection system has its own software architecture, which includes the device layer, data layer, application layer and display layer. The device layer is used to manage the multi-mode gateway and the ski equipment connected to the security protection system; the data layer is used to manage and process the static and dynamic data that are connected; the application layer is used to provide multiple preset applications for users to call to realize various functions; and the display layer is used to display the processing results of the application layer.
[0239] For example, the application layer provides a visual display application of the device location. At this time, the display layer can see the location distribution information of each device on the electronic map. At this time, in order to overcome the problem of excessive amount of location data under massive users, it is necessary to perform interpolation simulation on discrete location information. The interpolation simulation method includes determining the curve type and curve curvature of the curve based on the straight-line distance between two adjacent location information and the time interval between the two location information, generating a simulation curve based on the determined curve type and curve curvature, and using the simulation curve as the path between the two location information.
[0240] For example, the application layer provides a task allocation algorithm for rescue personnel when an alarm occurs. At this time, the display layer can provide the preferred 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 the sensor data. The data label can be a label that has an identification function on the sensor data, such as the sensor ID that generates 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.
[0241] In actual scenarios, the server is set up in the cloud, and by collecting multimodal big data from all snowshoe equipment, it is trained and extrapolated by the intelligent computing center to generate an AI model for skiing action guidance, safety tips and parameter analysis, and then sent to users with fixed points, directions and targets. Since cloud computing has defects such as transmission delay and computing delay, and poor real-time performance, part of the computing tasks can also be completed on the snowshoes to achieve the combination of cloud computing and edge computing. Certain data processing and data fusion can also be performed on the multimode gateway side to achieve better data response.
[0242] In one embodiment, the security protection module further includes:
[0243] A communication module unit, wherein the communication module is equipped with short-distance communication and long-distance communication, wherein 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.
[0244] 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 are each other's primary and standby communication channels. 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 standby communication links use different communication standards to achieve more robust communication links.
[0245] In some extremely harsh communication environments, the aforementioned primary and backup communication channels may fail. At this time, as another solution, ski equipment and electronic equipment can use the human body as a communication medium, that is, human body communication (HBC) technology, through low-frequency (typically 125KHz) signal communication, the vital sign watch and snowshoe equipment each have an electrode in contact with the skin. HBC technology is a short-range communication (also known as near-field communication) method that uses the human body as a digital signal transmission medium.
[0246] In one embodiment, the security protection module further includes:
[0247] The multi-mode positioning unit is used to connect to the skiing equipment of the skier through the multi-mode gateway to obtain the positioning information of the skier.
[0248] In this embodiment, the aforementioned position positioning can adopt the Beidou positioning system, etc., which not only provides position information, but also provides functions such as ski area restriction. The ski equipment has built-in ski trail maps and electronic fences. When it detects that the skier's current position is outside the ski trail, an alarm is sent to prevent the skier from deviating from the ski trail. In order to further improve the positioning accuracy, RTK differential data technology can also be used. RTK data can be broadcasted by a multi-mode gateway, and all devices within the coverage range of the multi-mode gateway can receive the broadcasted RTK data. Fig.18 In the event of an accident, the Beidou satellite may not be able to locate normally due to the obstruction of the antenna, and may not be able to accurately determine the position of the skier. At this time, multi-mode positioning can be used to provide backup positioning. There are more than 3 multi-mode base stations around the device, and the base stations are not in the same straight line. The positioning process is as follows: the device performs ranging operations with 3 multi-mode base stations respectively, and the 3 ranging results and signal strengths are aggregated to the server. The server can determine the approximate position of the skier through the ranging results and the multi-mode gateway position, and use the signal strength to increase the positioning accuracy.
[0249] In one embodiment, the security protection module further includes:
[0250] An abnormality alarm unit, used to determine whether the skier has an abnormality according to the skier's positioning information and communication status;
[0251] 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.
[0252] In this embodiment, Fig.19 As shown, the ski equipment sends beacons with ID and location information regularly (e.g., 10 seconds), and the multi-mode gateway can know the location of the ski equipment. If the communication fails due to an accident where the skier slides off the ski slope or gets stuck in the snow, the alarm information and location information cannot be sent to the multi-mode gateway. If the multi-mode gateway does not receive the beacon of the ski equipment for more than a certain period of time (e.g., 20 seconds), it can be inferred that the skier may have a problem, and personnel can be assigned to search for the skier near the multi-mode gateway where the ski equipment last communicated (plus the last sent location information).
[0253] The snowshoe device is connected to the ski pole via short-range wireless communication, and the sensors sampled by the ski pole are collected and analyzed centrally. The snowshoe device can be connected to the mobile phone via Bluetooth or WiFi, and can establish a connection with the server through the mobile phone gateway. The snowshoe device and the mobile phone can share positioning information and sensor data. The mobile phone has a dedicated app to collect all the status data of the skier and provide a connection to the server.
[0254] Fig. 20 Schematic diagram of the logic framework of the security protection system provided by the present disclosure. Fig. 20 As shown, the alarms that may be generated by the safety protection system generally come from three aspects, which may be ski equipment, vital sign watches and beacon timing equipment.
[0255] Both ski equipment and vital sign watches collect various state parameters of skiers through their own sensors. When abnormal vital signs of skiers are detected, such as hypothermia, abnormal heart rate, long-term inaction, etc., when abnormal posture of skiers is detected, such as falling, flipping, excessive acceleration, inconsistent posture of feet, etc., when abnormal equipment of skiers is detected, such as separation of snowboard and snowshoes, snowshoes falling off, etc., alarm information is sent to the multi-mode gateway through long-distance communication, and the current location information is carried at the same time. If Beidou positioning is not turned on, positioning is turned on immediately, and the location information is transmitted to the multi-mode gateway after obtaining the location information. After receiving the alarm information, the multi-mode gateway sends it to the server, and the server assigns the nearest rescue personnel to the scene for rescue according to the location information of the alarm. Furthermore, when the posture of the skier is detected to be abnormal, the ski equipment sets emergency braking measures, and a parachute can be placed on the snowshoes or the backpack of the skier to reduce the speed of the skier. The emergency braking measures are triggered according to whether the skier's skiing speed exceeds the preset speed threshold, or whether the skier exceeds the safety range, or the skier manually triggers it to further protect the safety of the skier.
[0256] Other accessory components include a sound input device for acquiring external sound, such as a microphone; a sound output device for outputting sound information, such as a speaker; and a light prompt device for outputting light information, such as a flashlight. Sound and flash alarms are used to help search and rescue personnel find skiers, especially at night.
[0257] 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.
[0258] In this embodiment, one or more of the following sensors are included:
[0259] Pressure sensors to detect the force a skier applies to their ski equipment;
[0260] 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;
[0261] Contact sensors, which detect the contact between the skier and the ski equipment;
[0262] Distance sensors for detecting the relative positions of the separate parts of the ski equipment;
[0263] Body temperature sensor, used to detect the skier's body temperature data;
[0264] Heart rate sensor, used to detect the skier's heart rate data;
[0265] A position sensor for detecting the current position of the ski equipment;
[0266] Angle sensor, used to detect the change in angle between the skier and the ski equipment during skiing;
[0267] An image sensor for acquiring images during skiing;
[0268] Strain sensors are used to obtain the deformation state of ski equipment;
[0269] A temperature sensor is used to obtain temperature information of ski equipment;
[0270] Speed sensor, used to obtain the linear speed and angular speed of the ski equipment;
[0271] Humidity sensor, used to obtain the humidity status inside the ski equipment;
[0272] When using a sensor group applied to smart skiing equipment, the sensor data collected by multiple sensors can use data fusion technology to improve the correlation of sensor data, which mainly includes the following methods: when the number of data samples of sensor data is insufficient, the data is expanded by data augmentation. A data augmentation method includes: extracting a feature matrix of an existing data sample, and obtaining a number of basic matrices according to a plurality of feature matrices; determining a plurality of augmentation parameters in the augmentation process by generating a random sequence; obtaining a processed feature matrix after operating the basic matrix based on the plurality of augmentation parameters; and generating an augmented data sample based on the processed feature matrix. In this way, the augmentation operation of the data sample is realized.
[0273] The data fusion includes the following steps: extracting the features of some categories of sensor data through the first model, and fusing the extracted features by splicing, segmentation, encoding and other technologies. The spliced features are standardized or AI-changed, and the data is further identified based on multiple dimensions to improve the fusion effect of the sensor data. The fused data features are processed using the attention mechanism. In addition to the aforementioned sensor data fusion, a study on the reliability and mutual confirmation of sensor data based on the correlation between sensors is also provided. For example, the health status of the sensor is first identified, which is divided into offline identification and online identification, where offline identification includes when the sensor has calibration failure, power failure, communication failure and other phenomena, then the health status is faulty; online identification includes determining whether the sensor data of the sensor is consistent with the overall situation based on the real-time state parameters of the skiing process and the characteristics of the posture monitoring data, so as to determine whether the sensor is faulty.
[0274] The correlation between sensors is determined in the following way. Step 1: According to the spatial distribution information and data type of the sensor group, a spatial coordinate model of each sensor position is established; Step 2: According to whether the detection data exceeds the preset threshold, the first sensor set that exceeds the threshold is determined. Step 3: According to the first sensor set, combined with the correlation distance threshold, the second sensor set is identified; Step 4: The positions of each sensor in the second sensor set are located, and a three-dimensional multi-faceted space is constructed according to the principle of maximizing the spatial volume to obtain an effective sensing area. Each sensor in the effective sensing area can achieve mutual verification and strong spatial correlation.
[0275] The present invention also provides an intelligent skiing equipment, including a self-generating ski board of the intelligent skiing equipment, and / or a power generation device applied to the intelligent skiing equipment, and / or a piezoelectric device applied to the intelligent skiing equipment, and / or an action guidance system of the intelligent skiing equipment, and / or a communication system for the intelligent skiing equipment. The ski board body of the present invention can be provided with an electric component at the front and rear to ensure the front and rear balance of the ski board. The electric component can change the windward direction as the direction of movement of the ski board changes, and the windward blades always face the wind to ensure the maximum amount of wind received, thereby converting wind energy into electrical energy for self-generation. The present invention can also repeatedly press the pressure power generation component through the pressure from the bottom of the skier's feet and the front side of the lower leg, so that the electric energy generated by the pressure power generation component can be used to power the electrical component through the charging circuit. The present invention generates a continuous source of electric energy for power supply by generating electricity separately, thereby avoiding the influence of the skiing environment on the battery performance as much as possible for power supply. 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 user's correct skiing movements through AI action guidance, which is beneficial to ensuring the user's skiing safety.
