Description

Technical Field

[0001] This invention relates to the field of artificial ski resorts, and provides an artificial ski resort based on a box structure and its control system. Background Technology

[0002] Artificial ski resorts are facilities that simulate natural skiing environments through artificial means, aiming to provide suitable terrain for skiing, especially in areas without natural snow or with short ski seasons. With the global popularity of skiing, particularly in areas where climate conditions are unsuitable for natural skiing, artificial ski resorts have become an important facility to meet the needs of ski enthusiasts and professional athletes. Artificial ski resorts not only extend the ski season, making skiing no longer limited to winter, but also provide a safe and controlled skiing environment for beginners and trainees.

[0003] Currently, artificial ski resorts typically rely on artificial snowmaking technology to operate. Water is converted into snow using snowplows and snowmaking systems, which is then applied to the ski slopes. These systems use high-pressure equipment to mix water and air and spray it into cooled air, thus generating snowflakes. Most modern artificial ski resorts are also equipped with advanced slope maintenance equipment, such as snowplows and snow groomers, to ensure a smooth snow surface and high-quality ski runs. Furthermore, artificial ski resorts can regulate snow hardness through temperature control systems to ensure optimal skiing conditions under various weather conditions. Some resorts even use refrigeration technology during the non-winter season to maintain a constant temperature environment, simulating natural skiing conditions.

[0004] However, while artificial ski resorts have provided skiers with more options, most still face several challenges. First, skiing is inherently a high-risk sport, and the artificial snow commonly used in these resorts poses a significant challenge for beginners. The hardness and gliding properties of artificial snow make it prone to falls and injuries, resulting in a consistently high injury rate among beginners. Second, the production of artificial snow requires substantial amounts of water and electricity, leading to high operating costs, especially in areas requiring large-scale snow production. Maintaining the quality and performance of the slopes necessitates constant snow preparation and resurfacing, a costly practice that is unacceptable for some indoor ski resorts primarily for instruction. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide an artificial ski resort and its control system based on a box structure, in order to solve the problems mentioned in the background art. The box structure is composed of several bottom ribs, columns, insulated top plates, and insulated vertical plates. The box structure is equipped with a display device, a detector for detecting the direction of human movement, and a ski mat device with an electrically adjustable tilt angle.

[0006] Furthermore, the display device includes a first display unit installed in front of the ski mat device in the direction of operation and a second display unit installed on both sides of the ski mat device.

[0007] Furthermore, the detector includes a first motion detector and a second motion detector, which are respectively mounted on top of the first display unit and the second display unit.

[0008] Furthermore, the ski mat device includes a drive unit and a ski mat mounted on the drive unit.

[0009] Furthermore, one end of the drive device is hinged to the floor inside the box structure via a hinge seat, and the other end is fixedly connected to the floor inside the box structure via a hydraulic rod.

[0010] This invention, through its box-like structure design, allows the various components of a ski resort to be quickly assembled like building blocks, significantly shortening the construction cycle. Furthermore, when a component needs repair or replacement, it can be easily disassembled for repair or replacement and then reinstalled, without requiring large-scale modifications to the entire ski resort.

[0011] In terms of facilitating teaching, the environment inside the box-structure ski resort can be precisely controlled, including temperature, humidity, and wind speed. All teaching equipment and facilities are concentrated inside the box structure, facilitating unified management and operation by teachers and improving teaching efficiency. The box-structure ski resort can be quickly adjusted according to teaching needs, such as changing the difficulty settings of the ski machines or adjusting the content of the display screens, to accommodate the learning needs of skiers of different levels. Furthermore, the teaching mode, equipped with emergency braking devices on the ski machines and a box-structure design, allows for rapid stopping of the ski machines in emergencies, ensuring skier safety and significantly enhancing safety compared to outdoor teaching.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] The purpose of this invention is to provide an artificial ski resort based on a box structure and its control system. The box structure comprises a base plate, uprights, and a top plate. Inside the box structure are installed an air supply system, a display device, a displacement sensing system, an attitude sensing system, and a fully automatic skiing device with electrically adjustable tilt angle. The fully automatic skiing device, display device, attitude sensing system, and displacement sensing system are all electrically connected to a terminal control system, which is electrically connected to a user-end operating system.

[0022] One end of the fully automatic ski equipment is hinged to the box structure floor, and the other end is connected to the box structure floor through a lifting mechanism. Driven by the lifting mechanism, the overall inclination of the equipment can be adjusted, and the operating speed of the fully automatic ski equipment can be coordinated to achieve the descent speed in a simulated skiing scene.

[0023] The display equipment uses a large indoor LCD screen. Both the fully automatic ski equipment and the display equipment are installed inside the enclosure structure, with the display equipment distributed around the left, right, and front of the fully automatic ski equipment. The display equipment can display dynamic simulated environmental images.

[0024] The displacement sensing system and attitude sensing system can monitor the skier's displacement and posture changes in real time, respectively. Both provide accurate feedback information to the terminal control system, monitoring, processing, and responding to the skier's relative position and posture data. The functions of both systems are achieved through several detectors located inside the enclosure structure, which detect the direction of human movement. These detectors can capture real-time images of the top of the fully automatic ski equipment and the skier.

[0025] When a skier uses fully automatic ski equipment, the detector transmits the captured images to the connected terminal control system. The terminal control system analyzes the skier's relative position and body posture on top of the fully automatic ski equipment in real time based on the images, and adjusts the operating speed and inclination of the fully automatic ski equipment in real time.

[0026] Specifically, the displacement sensing system includes a position data processing and analysis unit; the attitude sensing system includes an attitude information extraction unit and an attitude database.

[0027] The posture database stores several standard posture coordinates for comparison with the posture coordinates extracted by the posture information extraction unit. The posture information extraction unit extracts posture information based on the image presented by the receiving detector. During this process, the skier wears equipment clothing with specific feature markings to aid identification and simplify the processing. The posture information extraction unit presents the relative positions of the skier's head, torso, limbs, and key joints as points and lines on a two-dimensional grid within the unit, forming the skier's posture coordinates. These coordinates are compared with the pre-recorded standard posture coordinates in the posture database to identify the skier's posture behavior and automatically control the operation of the fully automatic skiing equipment based on this behavior.

[0028] For example, the posture database stores basic gliding postures, normal gliding postures, turning postures, and deceleration postures. When the skier is in the basic gliding posture, the posture information extraction unit detects that the posture data shows the feet are the same width as the shoulders, the knees are bent forward, the kneecap is above the instep node, the drive is in a numerical state, the arms are on both sides of the torso node, and the forearms are bent; this is detected as the basic gliding posture. At this time, the terminal control system controls the fully automatic skiing equipment to operate at a low speed. When the posture information extraction unit detects an abnormal posture data state, the terminal control system controls the fully automatic skiing equipment to stop immediately and simultaneously level the tilt angle to prevent injury.

[0029] The location data processing and analysis unit intelligently identifies the skier's position on the fully automatic ski equipment, generates position coordinate information, and calculates the deviation between this information and the equipment's standard line and center line. This deviation is categorized as lateral and longitudinal. The terminal control system then controls the operation of the fully automatic ski equipment based on the difference between the lateral and longitudinal deviations.

[0030] The process of deviation calculation and controlling the operation of fully automatic skiing equipment based on the deviation is as follows:

[0031] Longitudinal deviation is determined based on the standard line in the longitudinal direction of the fully automatic ski equipment (the direction of travel of the ski blanket on top of the automatic ski equipment). The standard line is set at the center line in the longitudinal direction of the fully automatic ski equipment, and the longitudinal deviation is the displacement vector deviation value between the skier and the standard line.

[0032] Lateral deviation is determined based on the centerline of the fully automatic ski equipment in the lateral direction (perpendicular to the running direction of the ski mat at the top of the equipment). The centerline is set at the midline of the fully automatic ski equipment in the lateral direction, and the lateral deviation is the displacement vector deviation value between the skier and the centerline.

[0033] When a longitudinal deviation exists, the system controls the acceleration and deceleration of the fully automatic skiing equipment based on the positive or negative value of the longitudinal deviation. For example, when the skier is 30cm ahead of the standard line (beyond the standard line downwards), the longitudinal deviation is positive, with an offset of 30. In this case, the snow carpet on top of the automatic skiing equipment is accelerated to help the skier correct the offset. When the skier is 20cm behind the standard line (behind the standard line upwards), the longitudinal deviation is negative, with an offset of 20. In this case, the snow carpet on top of the automatic skiing equipment is decelerated to help the skier move downwards to correct the offset.

[0034] When lateral deviation exists, the system compares the absolute value of the lateral deviation with the danger value. If the lateral deviation is too large, the system controls the fully automatic ski equipment to gradually stop operating, ensuring that the skier will not be in danger due to deviating from the ski slope.

[0035] Therefore, the terminal control system directly identifies key parts of the skier's body and measures the spatial relative positions of each key part through the position data processing and analysis unit and the posture information extraction unit, thereby controlling the operation of the fully automatic skiing equipment based on the posture information.

[0036] The air supply system is installed on the floor of the enclosure, with its outlets facing the direction of operation of the fully automatic ski equipment. When the skier is on the equipment, the air supply system blows air towards them, simulating a realistic chemical environment and enhancing the realism of the simulation.

[0037] Therefore, using a box-like structure to design an artificial ski resort, and installing ski machines, temperature control equipment, air supply equipment, surround display screens, cameras, audio equipment, etc., inside a single box-like structure, brings several advantages:

[0038] 1. Easy to assemble and disassemble: The box-type structure design allows the various components of the ski resort to be quickly assembled like building blocks, greatly shortening the construction cycle. Moreover, when a component needs repair or replacement, it can be easily disassembled for repair or replacement and then reinstalled without requiring large-scale modifications to the entire ski resort.

[0039] 2. Easy to modify: The internal space of the enclosure can be adjusted and optimized as needed to accommodate different ski machine models, temperature control devices, or other auxiliary equipment. As technology advances, ski resort equipment may require upgrades. The enclosure design makes such upgrades easier, requiring only the replacement or upgrading of the appropriate components.

[0040] 3. Easy to move; Since the entire ski resort is installed inside a box-like structure, it can be easily moved to different locations, such as city centers, parks, and resorts, to meet the skiing needs of different areas. For occasions requiring temporary ski resort setups, such as music festivals and exhibitions, the box-like structure ski resort can be quickly assembled and disassembled, making it ideal for such short-term, high-intensity use scenarios.

[0041] 4. Easy assembly and expansion: The modular design of the box-structure ski resort allows for the addition or reduction of boxes as needed to expand or shrink the resort's size. By adding extra boxes, the area and facilities of the ski resort can be easily expanded to accommodate more skiers and higher skiing demands.

[0042] 5. Easy to customize; the box-structure ski resort can be customized according to the customer's individual needs, such as selecting specific ski machine models, temperature control ranges, air outlet methods, etc.; it can also design unique themes and styles according to the customer's preferences and needs, such as ice and snow world, polar adventure, etc., to increase the attractiveness and competitiveness of the ski resort.

[0043] 6. Facilitates commercialization; the construction cost of box-structure ski resorts is relatively low and they can be reused, which greatly reduces long-term operating costs. Since the ski resort can be moved to different locations and occasions, it can attract more skiers and spectators, thereby increasing revenue and profitability.

[0044] 7. Facilitates Teaching: The environment inside the box-structure ski resort can be precisely controlled, including temperature, humidity, and wind speed. All teaching equipment and facilities are concentrated inside the box structure, facilitating unified management and operation by teachers and improving teaching efficiency. The box-structure ski resort can be quickly adjusted according to teaching needs, such as changing the difficulty settings of the ski machines or adjusting the content of the display screens, to accommodate the learning needs of skiers of different levels. Furthermore, the teaching mode, equipped with emergency braking devices on the ski machines and a box-structure system, allows for rapid stopping of the ski machines in emergencies, ensuring skier safety. Compared to outdoor teaching, this significantly enhances safety.

[0045] See Figure 1-4 An artificial ski resort based on a box structure includes a frame structure consisting of several bottom reinforcing bars 1 and columns. An insulated roof plate 3 and several insulated vertical panels 2 are fixedly connected to the frame structure. The bottom reinforcing bars 1, columns, insulated roof plate 3, and several insulated vertical panels 2 together constitute the box structure.

[0046] The housing contains a ski mat device 5 with an electrically adjustable tilt angle. A first display unit 71 is installed in front of the ski mat device 5 in its direction of travel, and second display units 72 are installed on both the left and right sides of the ski mat device 5. A first motion detector 81 and a second motion detector 82 are respectively installed on top of the first display unit 71 and the second display unit 72. The first motion detector 81 and the second motion detector 82 detect lateral deviation and longitudinal deviation respectively, and send the images to the position data processing and analysis unit.

[0047] Preferably, both the insulated roof panel 3 and the insulated vertical panel 2 have an internal insulation layer. The insulated roof panel 3 and the insulated vertical panel 2 effectively reduce heat exchange between the ski resort and the outside environment, maintaining a stable indoor temperature. In winter, they prevent heat loss and keep the ski resort warm; in summer, they block external heat from entering, lowering the indoor temperature and improving the comfort of the ski resort.

[0048] Preferably, both the first display unit 71 and the second display unit 72 are equipped with speaker units 80 on their tops. Thus, the speaker units 80 are arranged around the ski mat device 5, reproducing a realistic skiing sound experience as much as possible, greatly enhancing the skier's immersion. For skiing beginners, ski simulators are not only recreational tools but also important training equipment. During training, skiers may lose their balance due to excessive speed or improper operation. At this time, the simulated skiing environment sounds from the speaker units 80 can serve as a warning signal, reminding the skier to pay attention to safety. For example, when the skier is about to approach the edge of the simulator or an obstacle, the speaker units can emit alarm sounds or prompts to help the skier adjust their posture and speed in time to avoid accidents.

[0049] Preferably, the ski mat device 5 includes a drive device 51 and a ski mat 54 mounted on the drive device 51. The drive device 51 is an electrically driven roller conveyor. The cooperation principle between the ski mat 54 and the drive device 51 is described in Chinese Utility Model Patent Application No. CN201720819618.X, published on June 22, 2018. As this is prior art, it will not be described again. One end of the drive device 51 is hinged to the floor inside the box structure via a hinge seat 52, and the other end is fixedly connected to the floor inside the box structure via a hydraulic rod 53.

[0050] Preferably, side guardrails 55 are fixedly connected to both sides of the top of the drive device 51. The side guardrails can prevent skiers from accidentally falling or sliding off the device during use. Especially when the device is running at high speed, the side guardrails can provide an effective barrier for skiers and reduce the risk of injury.

[0051] Preferably, a front guardrail 56 is provided on the front side of the drive device 51 in the direction of travel. The front guardrail 56 can act as a barrier to prevent skiers from sliding off the equipment due to loss of control or improper operation. After the equipment stops, skiers can also slowly slide down and hold onto the front guardrail 56, reducing the risk of injury to the skiers.

[0052] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
