[0002] With the continuous development of indoor simulated skiing technology, more and more facilities have emerged to meet the needs of ski enthusiasts, professional athletes and ski equipment manufacturers. Indoor simulated skiing can not only provide ski enthusiasts with a worry-free skiing experience in all seasons, but also provide athletes with a more professional training environment.

[0003] As an efficient indoor simulated skiing environment, the artificial ski house is usually equipped with a series of advanced equipment to simulate the environmental conditions when skiing. The snow drifting system can make snow, simulating the effect of natural snowfall, providing skiers with a more realistic skiing experience.

[0004] However, the existing snow drifting systems in artificial ski houses can usually only drift snow vertically downwards, which has certain limitations when simulating natural snowfall. In real snow scenes, the falling of snowflakes is random, and is affected by many factors such as wind speed, airflow, and humidity. The trajectory and falling direction of snowflakes are changeable and dynamic. Although the existing vertical snow drifting systems can imitate the effect of falling snowflakes, they cannot effectively reproduce the changes in wind and snow encountered by skiers during the sliding process, nor can they simulate the real scene of snowflakes drifting in the air. Therefore, the existing snow drifting systems fail to achieve a more realistic and changeable simulation effect, which limits the realism of the natural snow scene that skiers can experience in the simulated environment, and affects the effect of skiing training and entertainment experience.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] See also Figure 1-9 The object of the present invention is to provide a snow making control system and method based on a snow blanket.

[0037] The snow-making amount control system based on the snow blanket is installed inside the artificial box-type snow house. The snow house is equipped with a ski machine 8, a snow drifter 2 (hanging snow machine), an air supply system and a terminal control module. The snow drifter 2 can use, for example, a Ferguson landscape snow drifter (models FAS-1300G, FAS-3500G, F26 and F36). The air supply system includes an air supply fan 5 and a refrigerator 4 installed inside the box-type snow house. The control system achieves the real effect of snowflakes hitting the body during skiing by accurately controlling the coordinated work of the ski machine 8, the snow drifter 2, the air supply fan 5 and the refrigerator 4, while ensuring that the performance of the snow drifter 2 is not affected. This air supply system uses the principles of aerodynamics to ensure that snowflakes can be blown evenly and effectively on the user, or through different air supply modes, and in conjunction with the ski machine 8 to automatically control the snow-making amount of the snow drifter 2, complete different modes of snow-making modes, meet the simulation of real snow drifting scenes in different situations, and enhance the user experience of skiers.

[0038] Specifically, the ski machine 8 is provided with a conveyor-type ski carpet 81. The ski machine 8 is installed in the center of the artificial box-type snow house and is arranged along the length direction of the container so that the user has enough space to ski. The ski carpet 81 is transmitted in the form of a conveyor belt on the ski machine 8. The ski machine 8 is electrically connected to a variable frequency speed regulator. The transmission speed of the ski carpet 81 is controlled by the variable frequency speed regulator. The variable frequency speed regulator is electrically connected to the terminal control module. The terminal control module controls the variable frequency speed regulator and can adjust the speed according to the needs of the user.

[0039] At the same time, the snow drifter 2, the air blower 5 and the refrigerator 4 are all electrically connected to the terminal control module. Under the control of the terminal control module, the power control and wind direction adjustment of the snow drifter 2 and the air supply system can be linked by the signal of the operating status of the ski machine 8 (such as start, stop, acceleration, deceleration, angle adjustment).

[0040] The box-type snow house involved in this scheme includes a cube frame structure composed of several bottom ribs and columns. The top of the cube frame structure has a top plate, and several vertical plates are installed around it. The bottom plate is installed on the frame composed of four bottom ribs. The bottom plate divides the box structure into two spaces, upper and lower. The space on the top of the bottom plate is divided into a ski cabin and an equipment cabin by a partition. The air blower 5 and the refrigerator 4 are installed in the equipment cabin and isolated from the ski cabin; the ski machine 8, the snow drifter 2 and some display devices are installed in the ski cabin. The space at the bottom of the bottom plate is the bottom cabin, which can be used for wiring and installing ventilation pipes and electrical equipment, which can further optimize the spatial layout inside the artificial box-type snow house.

[0041] The system also includes a displacement sensing system installed inside the ski cabin. The displacement sensing system can monitor the displacement changes of the skier in real time, provide accurate feedback information to the terminal control system, and monitor, process, and respond to the relative position information of the skier. The function of the displacement sensing system is realized by a number of detectors arranged inside the box structure. The detectors can use high-definition cameras to shoot the movement of the human body on the ski machine 8; a number of detectors can shoot the top of the entire ski machine 8 and the skier in real time and from multiple angles. When the skier is using the ski machine 8, the detector transmits the captured image to the terminal control system to which it is connected. The terminal control system analyzes the relative position of the skier on the top of the ski machine 8 in real time based on the image, and adjusts the operating speed and slope of the ski machine 8 in real time.

[0042] Specifically, the displacement sensing system includes a position data processing and analysis unit; the position data processing and analysis unit generates position coordinate information by intelligently identifying the position of the skier on the ski machine 8, compares the position coordinate information with the initial position set by the device, and calculates the deviation. The terminal control system controls the operating state (tilt and operating speed) of the ski machine 8 according to the difference in deviation. For example, when the skier is 30 cm ahead of the standard line (beyond the initially set standard line downward), the deviation is positive and the offset is 30. At this time, the snow blanket on the top of the automatic ski equipment is controlled to increase in speed, driving the skier to correct the offset; when the skier lags behind the standard line (lags behind the standard line upward) by 20 cm, the longitudinal deviation is negative and the offset is 20. At this time, the snow blanket on the top of the automatic ski equipment is controlled to decelerate, driving the skier to move downward to correct the offset.

[0043] At the same time, the inclination angle (ski slope) of the ski machine 8 can be adjusted by the instructor manually setting or by timing setting to simulate the change of slope during skiing. Specifically, one end of the ski machine 8 is hingedly connected to the bottom plate through an articulated seat, and the other end is fixedly connected to the bottom plate through a hydraulic rod. When the hydraulic rod is extended or retracted, the inclination angle between the ski machine 8 and the bottom plate can be controlled to increase or decrease.

[0044] The ski machine 8 involved in this solution can be controlled by a terminal control module to complete functions such as tilt angle adjustment, start, stop, and adjust the operating speed. At the same time, the terminal control system can monitor its operating status, obtain its operating data, and control the operation of the air supply system based on the operating data.

[0045] The air supply system of this scheme includes a refrigerator 4, a blower 5, a switching device 6 installed in the equipment room, and a bottom bellows 7, a top bellows 3, and a return air port 111 installed inside the ski cabin. The refrigerator 4, the blower 5, and the switching device 6 are all electrically connected to the terminal control system, and the blower 5 is electrically connected to the variable frequency speed regulator. The air outlet of the refrigerator 4 is connected to the switching device 6 through a pipeline, and the blower 5 is installed on the pipeline connecting the refrigerator 4 and the switching device 6. The blower 5 has multiple air inlets, one of which corresponds to the air outlet of the refrigerator 4 and can suck the cold air blown out by the refrigerator 4 into the pipeline. The other air inlets are open to the equipment room. The output end of the blower 5 is connected to the input end of the switching device 6 through the main line pipeline 51.

[0046] Specifically, the two air outlets of the switching device 6 are connected to the top wind box 3 and the bottom wind box 7 through the first branch pipe 601 and the second branch pipe 602. The first branch pipe 601 and the second branch pipe 602 complete the diversion of the air supply, and the switching device 6 can control the air volume of the air produced by the refrigerator 4 entering the two pipes.

[0047] Three sides of the air outlet 31 face the main pipeline 51, the first branch pipeline 601 and the second branch pipeline 602 respectively, and the switching device 6 is connected with the main pipeline 51, the first branch pipeline 601 and the second branch pipeline 602. The first branch pipeline 601 and the second branch pipeline 602 are arranged opposite to each other along the lifting direction of the air outlet 61.

[0048] Preferably, a lifting air outlet 61 is installed inside the switching device 6. The air outlet 61 is provided with an air inlet 65 on the side facing the main line pipeline 51, a first air outlet 66 on the side facing the first branch pipeline 601, and a plug 63 on the side facing the second branch pipeline 602. A lifting rod 62 is installed inside the switching device 6, and the output end of the lifting rod 62 is fixedly connected to the air outlet 61 through a connecting seat 621. The lifting rod 62 can drive the air outlet 61 to lift and lower. When the air outlet 61 is at the bottom, the plug 63 blocks the second air outlet 64. At this time, the cold air generated by the refrigerator 4 enters the air outlet 61 from the air inlet 65, and then enters the first branch pipeline 601 from the first air outlet 66. When the air outlet 61 is at the top, the entire air outlet 61 enters the first branch pipeline 601, and the cold air generated by the refrigerator 4 enters the second branch pipeline 602 from the second air outlet 64. When the air cylinder 62 controls the air outlet tube 61 to be located at different heights, the wind speed in the two channels can be adjusted.

[0049] A top bellows 3 is provided on the top of the partition between the ski room and the equipment room, a bottom bellows 7 facing the ski blanket 81 is installed on the bottom plate of the ski room, and the air supply fan 5 is connected to the top bellows 3 and the bottom bellows 7 respectively through the switching device 6 and the first branch pipe 601 and the second branch pipe 602 on the switching device 6; the switching device 6 can divert the wind blown out by the refrigerator 4 and control the air volume of the top bellows 3 and the bottom bellows 7. The airflow control in the box-type snow house can be completed by diverting, and the upper and lower wind forces cooperate to control the drifting trajectory of the snowflakes in the ski room as the natural wind during simulated skiing. One end of the return pipe 11 is installed on the bottom plate at the bottom of the equipment room, that is, the return pipe 11 passes through the bottom plate and penetrates the equipment room, and the other end of the return pipe 11 is connected to the return air port 111 installed inside the ski room.

[0050] The air outlets of the top wind box 3 and the bottom wind box 7 are both provided with wind direction adjustment mechanisms, which are electrically connected to the terminal control module, so that the air outlets of the top wind box 3 and the bottom wind box 7 can complete the function of adjusting the wind direction up and down. Specifically, the air outlets of the bottom wind box 7 and the top wind box 3 are both installed with air outlet grilles 71, and the air outlet grilles 71 are provided with a plurality of linked air induction plates 711, and the plurality of air induction plates 711 can adjust the inclination angle synchronously, and the bottom wind box 7 is installed with an adjustment motor 72, and the rotating shaft of one of the air induction plates 711 is fixedly connected to the output end of the adjustment motor 72, so that the inclination angle of the air induction plate 711 can be controlled by electric control, thereby adjusting the wind direction of the air outlet of the bottom wind box 7.

[0051] The cold wind generated by the refrigerator 4 inside the snow house provides a cooling effect inside, and at the same time, the cold wind can ensure that the snowflakes in the room will not melt when exposed to the wind. The cold wind is transported to the first branch pipe 601 and the second branch pipe 602 through the main line pipe 51, and the wind is supplied from the top and the bottom respectively, blowing the snowflakes produced by the snow drifter 2, forming cold wind with snowflakes to blow on the skiers. During skiing, the terminal control system will adjust the operating speed and slope of the ski machine as needed. This adjustment is determined based on the state of the skier. For example, when the skier brakes, the ski machine 8 is controlled to slow down, the corresponding air volume of the two air outlet boxes is reduced, and the inclination angle is slowly reduced. The wind speed of the two air outlet boxes is changed by the switching device 6, and the wind direction when the air outlet merges is changed.

[0052] Based on the above system, this solution provides a snow blanket-based snow making amount control method, which specifically includes the following steps:

[0053] S1. The detector takes images of the skier skiing on the ski machine 8 in real time and sends the images to the position data processing and analysis unit. A high-definition camera or other image acquisition device is installed at a key position of the ski machine 8 to ensure that the image of the skier during the skiing process can be captured in real time and clearly.

[0054] S2. The position data processing and analysis unit generates the position coordinate information of the skier, compares it with the initial position set by the device, and controls the operation state of the ski machine 8 by the difference obtained. In this step, after receiving the image, the position data processing and analysis unit automatically extracts the position information of the skier using image recognition technology and algorithms, and converts it into accurate three-dimensional coordinates. Subsequently, the generated skier position coordinate information is compared with the initial position coordinates preset by the device, and the displacement of the skier in each direction is calculated. Then, according to the difference in displacement, the operation state of the ski machine 8 is dynamically adjusted by the preset control algorithm.

[0055] S3. The ski machine 8 sends the running status data to the terminal control module, and the running status data includes the running speed and tilt angle of the ski carpet 81. The terminal control module controls the air supply system to control the air volume and the blowing angle of the wind in real time. In this step, the built-in sensor of the ski machine 8 collects the running status data in real time, including the running speed and tilt angle of the ski carpet 81, and sends the collected running status data to the terminal control module via wired or wireless means. The terminal control module adjusts the air volume and blowing angle of the air supply system in real time according to the received running status data and the preset air supply strategy to simulate the real skiing environment.

[0056] S4. The terminal control module controls the snow-making amount of the snow drifter 2 to make snow according to the set snow-making amount value or the wind speed. In this step, the terminal control module automatically sets the snow-making amount of the snow drifter 2 according to the operating state of the ski machine 8 or the preset snow-making amount value. During the control process, the snow-making mode in which the greater the wind volume, the greater the snow-making amount is preferentially followed.

[0057] The terminal control module controls the air supply system in the following aspects:

[0058] 1. The terminal control module controls the power of the blower 5 according to the running speed of the ski carpet 81. When the running speed of the ski carpet 81 increases, the terminal control module of the blower 5 controls the variable frequency speed regulator to increase the power of the blower 5, and simultaneously increases the air volume of the top bellows 3 and the bottom bellows 7, so as to achieve the purpose of increasing the overall air volume.

[0059] 2. The terminal control module adjusts the switching device 6 to distribute the air volume of the top wind box 3 and the bottom wind box 7 according to the tilt angle of the ski machine 8, and adjusts the angle of the air induction plate 711.

[0060] The adjustment of the blower 5, the switching device 6, and the air induction plate 711 can be controlled by computer intelligence, or a mode can be preset inside the terminal control module.

[0061] For example, when the running speed of the ski carpet 81 increases linearly, the terminal control module, i.e., the power of the intelligently controlled air blower 5, increases linearly accordingly, thereby simulating a scenario in which the air volume increases gradually with the increase in moving speed in reality.

[0062] For example, see Appendix Figure 6 The terminal control module is provided with a normal snow mode, in which the blower 5 is in low power mode, and the intersection of the inclination angles of the air induction plates 711 of the top bellows 7 and the bottom bellows 3 is adjusted to the position of the personnel at the top of the ski machine 8, thereby simulating the state of light wind and snow, which is suitable for the skiing state of vulgar beginners.

[0063] For example, see Appendix Figure 7 When the inclination angle of the ski machine 8 gradually increases, the terminal control module controls the air supply fan 5 to operate in high power mode, and at the same time controls the air outlet 61 in the switching device 6 to rise appropriately. At this time, the air volume entering the bottom wind box 3 after diversion increases, and the air volume of the top wind box 7 decreases. The air induction plate 711 on the bottom wind box 3 is intelligently adjusted according to the operation status data to maintain the same inclination angle as the ski machine 8, and the angle of the air induction plate 711 on the top wind box 7 is adjusted to blow obliquely downward. Therefore, when the snow drifting machine 2 makes snow, the top wind box 3 is used to drive the snowflakes to fall downward and control the initial flow direction of the snowflakes. When the snow drifting machine 2 merges with the wind force of the bottom wind box 7, the wind force of the bottom wind box 7 with a stronger wind force drives the snowflakes to blow toward the front of the skier, and the wind of the bottom wind box 3 accelerates the snowflakes and hits the front of the skier, thereby simulating the state of strong wind snow drifting or high-speed skiing, and adapting to the skiing state of high-speed skiers.

[0064] For example, see Appendix Figure 8 The preset modes include a free snowfall mode, in which the blower 5 is controlled to operate in a low power mode, the air outlet 61 is raised and lowered back and forth, and the air guide plate 711 is adjusted to an angle not opposite to the skier to disturb the interior of the snow house, and the snowflakes fall freely.

[0065] For example, see Appendix Fig. 9 , the blower 5 is turned off and the snowflakes fall freely.

[0066] In summary, in actual use, the snow blanket-based snow-making control system of the present invention can provide skiers with a real skiing experience through intelligent control. When the skier is on the ski blanket 81, the detector and displacement sensing system work, and several high-definition cameras located inside the ski cabin serve as detectors to capture the skier's position information in real time and transmit the position information to the position data processing and analysis unit, which generates the skier's real-time position coordinates through an intelligent algorithm, and compares it with the preset initial position to calculate the accurate deviation value. Accelerate or decelerate according to the deviation value.

[0067] At the same time, the snow drifter 2 is finely controlled by the terminal control module and makes snow according to the preset snow making amount value. Under the action of the air supply device, different motion trajectories are presented, further enhancing the realism and immersion of skiing. At the same time, the cold air generated by the refrigerator 4 is transported to the top bellows 3 and the bottom bellows 7 by the air supply fan 5. The switching device 6 intelligently adjusts the air volume distribution of the top and bottom bellows according to the inclination angle of the ski machine 8 and the running speed of the ski blanket 81. When the inclination angle of the ski machine 8 increases to simulate the high-speed skiing state, the switching device 6 guides more air volume into the bottom bellows 7, and at the same time, the top bellows 3 guides the snowflakes to fall downward through the light air volume, simulating the effect of strong wind and snow drifting.

[0068] Therefore, the system is highly flexible and customizable. The adaptive wind speed, snow production, and snowflake movement trajectory can be controlled manually or through the terminal control module in an intelligent way. Among them, the terminal control module has preset multiple skiing modes, such as normal snow drifting mode and free snow drifting mode, to meet the personalized needs of different skiers or in different states, and build a safe and realistic skiing scene.

[0069] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
