Description

Technical Field

[0001] The present invention relates to the technical field of indoor skiing, and in particular, to a simulation system and method for an artificial ski resort based on the Internet of Things. Background Art

[0002] Skiing is a winter sport carried out on snow, which is deeply loved by the general public. Due to environmental constraints, traditional ski resorts can usually only be opened in cold winter weather, and are mainly concentrated in high-latitude or high-altitude areas to ensure sufficient natural snowfall or low-temperature conditions to maintain the ski slopes. This means that for ski enthusiasts in most areas, the opportunity to ski is relatively limited, and they need to invest more time and cost to go to the ski resort. In contrast, the emergence of artificial ski resorts provides more choices for ski enthusiasts. Through artificial snow-making technology, artificial ski resorts can provide sufficient snow volume during the ski season and extend the business cycle of the ski resort.

[0003] However, the construction and operation costs of existing artificial ski resorts are relatively high. In contrast, indoor simulation ski machines have more advantages. It is not restricted by seasons and time, and skiing training can be carried out at any time and any place throughout the year. The ski machine has a low error tolerance and a large frictional resistance, which can help skiers form muscle memory faster and improve skiing skills.

[0004] When skiers experience skiing using a ski machine, the existing technology provides an immersive visual experience for skiers through VR glasses, enabling skiers to see virtual skiing scenes as if they were in a real ski resort. However, this experience is limited to the visual level and lacks real tactile, auditory, and environmental feedback. This limitation is likely to cause skiers who train skiing using a ski machine to be disturbed and not adapt to the external environment when transitioning from a virtual environment to a real ski venue, thereby increasing potential risks.

[0005] Furthermore, when skiers use a ski machine for skiing, there is still a possibility of danger. For example, a skier may fall due to a mistake in their movements. Especially for novice skiers, this situation often brings them additional psychological burdens.

[0006] The Chinese invention patent with the publicly disclosed patent name "An Intelligent Indoor Skiing Machine System and Method Based on Deep Learning" and the publication number CN116889718A includes a skiing machine body, a slope adjustment device, a data acquisition module, a database module, a display terminal module, and an analysis and control system. This patent collects images and audio of skiers, analyzes and identifies the collected data through a deep learning model, evaluates the actions of skiers, and provides skiing skill suggestions. Moreover, this patent can also change the inclination angle of the ski belt. When a skier is in a dangerous state such as falling, the intelligent assistance system can accurately identify it in a timely manner, and make the skiing machine gradually stop and change to a gentle slope to reduce the harm suffered by the skier and improve the safety of the skiing machine. However, the current detection of dangerous states mainly relies on monitoring the posture of skiers, which means it mainly monitors impending or already occurred dangers. In this case, skiers may not be able to react in time or may already have been injured. Therefore, this system needs to be further optimized to achieve an earlier warning and prevention mechanism, so as to better ensure the safety of skiers. Summary of the Invention

[0070] Embodiment 1

[0071] Please refer to Figures 1 - 3 , the present invention provides a simulation system for an artificial ski resort based on the Internet of Things, including a data acquisition module, a data processing module, a control module, a human-computer interaction module, and a database; the data processing module is respectively connected to the data acquisition module, the control module, the human-computer interaction module, and the database, and the control module is connected to the human-computer interaction module;

[0072] The data acquisition module includes an attitude data acquisition unit and an environmental data acquisition unit. The attitude data acquisition unit is used to acquire the attitude data of the skier, and the environmental data acquisition unit is used to acquire the environmental data of the artificial ski resort. The data acquired by the attitude data acquisition unit and the environmental data acquisition unit are respectively transmitted to the data processing module for further processing. The environmental data includes temperature, humidity, wind speed, wind direction, and snow surface condition. The attitude data includes, but is not limited to, the skier's posture, the skier's skiing speed, and the distance between the skier and the obstacle.

[0073] The data processing module includes an attitude data processing unit, an environmental data processing unit, and a judgment unit. The attitude data processing unit is used to process the attitude data transmitted by the attitude data acquisition unit connected to it. The environmental data processing unit is used to process the environmental data transmitted by the environmental data acquisition unit connected to it.

[0074] The judgment unit is respectively connected to the attitude data processing unit, the environmental data processing unit, and the database. The judgment unit receives the attitude data and environmental data respectively transmitted by the attitude data processing unit and the environmental data processing unit. The judgment unit retrieves reference data from the database and judges the attitude data and environmental data respectively according to the reference data. The judgment results are respectively sent to the human-computer interaction module and the control module connected to it.

[0075] The control module includes a device control unit and an environmental simulation unit.

[0076] The environmental simulation unit includes a first control unit and an environmental equipment group. The first control unit is connected to the judgment unit, and the first control unit controls the working mode of the environmental equipment group connected to it according to the signal transmitted by the judgment unit. The environmental equipment group includes a snow blower, a snowmaker, a refrigerator, and a hair dryer.

[0077] The device control unit includes a second control unit, an ice and snow clearing device, a ski machine, and a protection device. The second control unit is connected to the judgment unit, and the second control unit controls the ice and snow clearing device, the ski machine, and the protection device connected to it respectively according to the signal transmitted by the judgment unit.

[0078] The database is used to store the equipment information and personnel information of the artificial ski resort and to remotely store and call the information.

[0079] The human-computer interaction module is used to interact with the skier to provide skiing guidance or safety tips.

[0080] Specifically, the judgment unit judges the attitude data and environmental data respectively according to the reference data, and the judgment results are respectively sent to the human-computer interaction module and the control module connected to it. The above implementation includes the following steps:

[0081] Step S11: The judgment unit receives attitude data and environmental data; the judgment unit retrieves reference data from the database; the reference data includes standard attitude data, attitude danger threshold data, and safe environment threshold data;

[0082] Step S12: Compare the attitude data with the standard attitude data to obtain attitude result data;

[0083] Step S13: Judge the attitude result data against the attitude danger threshold data. If the attitude result data exceeds the attitude danger threshold data, execute Step S14; if the attitude result data does not exceed the attitude danger threshold data, execute Step S15;

[0084] Step S14: The judgment unit outputs data to the human-machine interaction module and the control module respectively; execute Step S16;

[0085] Step S15: The judgment unit outputs data to the human-machine interaction module; execute Step S16;

[0086] Step S16: Judge the environmental data against the safe environment threshold. If the environmental data exceeds the safe environment threshold, execute Step S17; if the environmental data does not exceed the safe environment threshold, execute Step S18;

[0087] Step S17: The judgment unit outputs data to the control module; execute Step S18;

[0088] Step S18: End.

[0089] Furthermore, the judgment unit outputs data to the control module, and the data includes instructions for adjusting the speed of the ski machine, adjusting the slope of the ski machine, turning on the ice clearing device, turning off the ice clearing device, and turning on the protection device;

[0090] If the judgment unit detects that the skier's attitude is a safe attitude but the ski machine has icing, the judgment unit outputs an instruction to turn on the ice clearing device to the control module;

[0091] If the judgment unit detects that the skier's attitude is a dangerous attitude but the ski machine has no icing, the judgment unit outputs an instruction for adjusting the speed of the ski machine or adjusting the slope of the ski machine and an instruction to turn off the ice clearing device to the control module;

[0092] If the judgment unit detects that the skier's attitude is a dangerous attitude and the ski machine has icing, the judgment unit outputs an instruction for adjusting the speed of the ski machine or adjusting the slope of the ski machine and an instruction to turn on the ice clearing device to the control module;

[0093] If the judgment unit detects that the skier's posture is a safe posture and the ski machine does not show icing, the judgment unit outputs an instruction to turn off the ice removal device or does not output an instruction to the control module.

[0094] It should be noted that the dangerous postures are divided into first-level dangerous postures, second-level dangerous postures, and third-level dangerous postures;

[0095] The first-level dangerous posture means that the judgment unit outputs an instruction to adjust the speed of the ski machine to the control module;

[0096] The second-level dangerous posture means that the judgment unit outputs an instruction to adjust the slope of the ski machine to the control module;

[0097] The third-level dangerous posture means that the judgment unit outputs an instruction to adjust the speed of the ski machine and an instruction to adjust the slope of the ski machine to the control module.

[0098] It should be noted that when the system issues an instruction according to the dangerous posture, it preferentially selects to adjust the speed of the ski machine, and then selects to adjust the slope of the ski machine. The reason is that the speed adjustment is relatively gentle and will not have too much impact on the overall experience of the skier, while the sudden change of the slope may make the skier feel uncomfortable.

[0099] Specifically, if the system detects that the skier's skiing speed is relatively fast, but the skier's posture and the distance between the skier and the obstacle are within the normal range, it is determined as a first-level dangerous posture, and the skiing speed of the skier is directly reduced by adjusting the speed of the ski machine, so as to reduce the potential risk caused by too fast speed; if the system detects that the skier's skiing speed is relatively fast and the skier's posture and the distance between the skier and the obstacle exceed the normal range, it is determined as a second-level dangerous posture, and the gravity component can be reduced by reducing the slope, so as to reduce the acceleration and skiing speed of the skier, and at the same time allow the skier to have enough reaction time to improve the skier's posture and the distance relationship with the obstacle; if the system detects that the skier's posture is in a falling state, it is determined as a third-level dangerous posture, and at this time, it is necessary to adjust the speed and slope of the ski machine at the same time to prevent the risk of secondary injury after the skier falls.

[0100] It should be noted that the obstacles include but are not limited to the edge of the ski machine and other skiers on the ski machine.

[0101] It should be noted that when the judgment unit judges the icing phenomenon, the judgment unit will also output a signal to the environmental simulation unit to adjust the indoor environment.

[0102] Specifically, the first control unit controls the working mode of the environmental equipment group connected to it according to the signal transmitted by the judgment unit. The above implementation includes the following steps:

[0103] Step S21: The first control unit receives the control signal of the judgment unit and parses it to obtain adjustment data;

[0104] Step S22: Adjust the working parameters of the environmental equipment group according to the adjustment data;

[0105] Step S23: Monitor the working status of the environmental equipment group and make a judgment; if the working status is abnormal, execute Step S204;

[0106] If the working status is normal, execute Step S25;

[0107] Step S24: Adjust the working parameters of the environmental equipment group again according to the adjustment data, and count the number of times of adjusting the environmental equipment group; if the number of times does not exceed the preset number of times, execute Step S23; if the number of times exceeds the preset number of times, execute Step S25;

[0108] Step S25: The first control unit outputs feedback data to the judgment unit.

[0109] It should be noted that in the above Step S25, after receiving the feedback data, the judgment unit analyzes the feedback data, and judges whether the device fails according to the analyzed signal. The above implementation includes the following steps:

[0110] Step S251: The judgment unit receives the feedback data and analyzes it to obtain the data to be warned;

[0111] Step S252: Compare the data to be warned. If the data to be warned exceeds the preset threshold, execute Step S253; if the data to be warned does not exceed the preset threshold, execute Step S254;

[0112] Step S253: The judgment unit outputs a control signal to the human-machine interaction module and the control module according to the judgment result, and execute Step S254;

[0113] Step S254: End.

[0114] It should be noted that in the above Step S22, the adjustment of the working parameters of the environmental equipment group includes the following methods:

[0115] Adjust the snowfall parameters of the snow machine, and the snowfall parameters include but are not limited to snowfall amount, snowfall direction, and snowfall time;

[0116] Adjust the snow-making parameters of the snow-making machine, and the snow-making parameters include but are not limited to snow-making amount and snow-making frequency;

[0117] Adjust the refrigeration parameters of the refrigerator, and the refrigeration parameters include but are not limited to refrigeration power and refrigeration time;

[0118] Adjust the blowing parameters of the hair dryer, and the blowing parameters include but are not limited to wind speed, wind direction, and blowing time.

[0119] It should be noted that the hair dryer is used for blowing to give skiers a real skiing experience. Especially when skiers are practicing turning, appropriate blowing can enhance the skiers' immersion.

[0120] Furthermore, the second control unit controls the ice and snow removal device, the ski machine, and the protection device connected thereto to work respectively according to the signals transmitted by the judgment unit. The ski machine adjusts the slope or speed according to the signals transmitted by the second control unit; the ice and snow removal device includes a surface snow scraping device, a lead screw, and a scraper control circuit. The scraper control circuit controls the surface snow scraping device connected thereto to contact the surface of the ski machine for snow or ice removal operations; the protection device includes a buffer air cushion, and the signals transmitted by the second control unit control the buffer air cushion to pop out.

[0121] It should be noted that the buffer air cushions are embedded on the upper side, lower side, left side, and right side of the ski machine. When the system detects that a skier has fallen, it immediately controls the buffer air cushions to pop out and stops the movement of the ski machine to protect the skier from secondary injuries;

[0122] It should be noted that in the ice and snow removal device, the surface snow scraping device is used to scrape the frozen parts on the ski machine; for the structure, installation position, and working mode of the surface snow scraping device, please refer to the Chinese utility model patent with the patent name "Surface Snow Scraping Device for Ski Magic Carpet Conveyor Belt" and the publication number CN217857546U. The surface snow scraping device in the present invention has the same principle and structure as the surface snow scraping device in the said patent, and the said patent has been publicly disclosed as the prior art, so it will not be described in detail here.

[0123] It should be noted that the ski machine includes a ski carpet, and skiers perform skiing actions on the ski carpet; the icing of the ski machine mentioned in the present invention means the icing of the ski carpet.

[0124] To prevent the surface snow scraping device from continuously scraping the ice on the ski carpet surface of the ski machine and thus causing damage to the ski carpet, the surface snow scraping device is controlled by a lead screw. When it is necessary to scrape the ice on the ski carpet, the lead screw pushes the surface snow scraping device to contact the ski carpet surface for ice scraping treatment; after the treatment is completed, the lead screw retracts the surface snow scraping device to make the surface snow scraping device leave the ski carpet surface.

[0125] It should be noted that the lead screw is controlled by the scraper control circuit;

[0126] In this embodiment, as Figure 3 shown, the scraper control circuit includes triodes Q1, Q2, Q3, Q4, and a motor U1;

[0127] Specifically, the base of the triode Q1 is set as the IN1 input terminal. The collector of the triode Q1 is connected to the collector of the triode Q2 and is connected to the power supply.
