[0031] Specific implementation method
[0032] In order to be able to understand the above objectives, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other if there is no conflict.
[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described here. Therefore, the protection scope of the present invention is not limited to the specific details disclosed below. Limitations of the embodiment.
[0034] The intelligent simulation indoor skiing safety system of the present invention is mainly suitable for indoor simulation skiing machines. The central processing system, image interactive system, real-time monitoring system, and alarm system combine with hardware skiing machines to form an intelligent simulation indoor skiing safety system. Of course, the present invention is not limited to the types of ski machines, and any technical solution adopting the present invention will fall into the protection scope of the present invention.
[0035] figure 1 It shows a block diagram of an intelligent simulation indoor skiing safety system of the present invention.
[0036] Such as figure 1 As shown, the present invention discloses an intelligent simulation indoor skiing safety system, which includes:
[0037] Central processing system, image interactive system, real-time monitoring system, alarm system;
[0038] The image interaction system, real-time monitoring system, and alarm system are all electrically connected to the central processing system;
[0039] The central processing system is used to receive and process the information collected by the real-time monitoring system and send instructions to control the alarm system and the image interactive system;
[0040] The real-time monitoring system is used for the safety monitoring of the teaching process; including the use of ultrasonic distance measurement to detect the distance between the trainees and obstacles during training, the use of laser induction and panoramic scanning to monitor the trainee's posture during training and the use of gravity sensing devices to sense Gravity changes of the students on the ski machine to realize the collection of the distance from the obstacle, body posture information and the center of gravity value of the students during training;
[0041] The alarm system is used for safety early warning; when the real-time monitoring system detects that the distance to the obstacle, the body posture information and the center of gravity value of the trainees during training reach the conditions for triggering the early warning, the central processing system issues instructions to make the alarm system Sound the voice alarm and stop the ski machine;
[0042] The image interactive system is used for real-time interactive delivery of teaching training content;
[0043] The alarm system includes a voice broadcaster and warning lights.
[0044] Further, when the students are training in ski teaching, the central processing system will put training courses on the ski machine in real time through the image interactive system to assist the students in training; the central processing system receives the data collected by the real-time monitoring system Body posture information, real-time analysis of the students' wrong actions, and dispatching the video interaction system to perform real-time video interaction to correct the students.
[0045] Further, an ultrasonic distance measuring sensor is used to detect the distance between the student and the obstacle during training, and the ultrasonic distance measuring sensor is arranged around the student's training suit for obstacle detection. When the distance between the trainee and the obstacle during training is less than the safety threshold, the central processing system issues an instruction to cause the alarm system to issue a voice alarm and stop the ski machine. For example, when trainees are training, they will be in danger due to the distance of their body movements close to touching the surrounding obstacles. The safety threshold of the distance can be set to 30cm. When the human body is still 30cm away from the obstacle, the central processing system will Trigger a control instruction to cause the alarm system to issue a voice alarm to warn the students. The preset distance is to allow the students to have enough distance to react to avoid touching accidents. At the same time, the central processing system stops the ski machine, and The number or location of the ski machine that sent the alarm information waited on the mobile phone of the staff at the scene, so that the staff rushed to the scene immediately to see if the students need help and improve the experience service of the students.
[0046] Further, the laser sensor adopts a laser sensor, which is arranged around the ski machine by using the laser sensor to emit a laser to sense the physical changes of the student, and upload the laser signal to the central processing system; the panoramic scanning adopts infrared thermal imaging panoramic The scanner performs thermal imaging scans on the students to monitor the real-time changes of the students’ status; the central processing system judges the students’ body based on the infrared thermal imaging images collected by the infrared thermal imaging panoramic scanner and combined with the laser signals collected by the laser sensor Posture information, and decide whether to trigger the alarm system according to the body posture information. The body posture information includes two states: a safe training posture and a dangerous training posture. When it is judged as a dangerous training posture, the central processing system issues instructions to cause the alarm system to issue a voice alarm and shut down the ski machine to prevent students Injured by touching an obstacle.
[0047] For example, when trainees are training, they use unreasonable training methods, which lead to body tilt or according to the real-time training of the image interactive system. When the correct image judges that there is a training danger, the central processing system stops the ski machine and sends an alarm message to the ski The number or location of the machine waits on the mobile phone of the staff at the scene, so that the staff can rush to the scene immediately to see if the students need help and improve the experience service of the students.
[0048] Further, the gravity sensing device includes a gyroscope, the gyroscope is set on the ski machine to monitor the change of the student's center of gravity during training, measure the student's center of gravity value on the ski machine, and send the center of gravity value to the central processing unit system.
[0049] When it is detected in real time that the center of gravity of the student deviates from the safety threshold range, the central processing system determines that the student is in a falling state at this time, and the central processing system will issue a control instruction to cause the alarm system to issue a voice alarm and stop the ski machine , And at the same time send an alarm message to the mobile phone of the staff at the scene, so that the staff immediately rushed to the ski machine where the alarm occurred to help the students.
[0050] The above-mentioned safety threshold range of the center of gravity value can be preset according to the weight of each student, and has different ranges for different students, which is more reasonable and humane.
[0051] It should be noted that the central processing system may use control equipment such as a computer, and the image interaction system may be implemented using virtual reality technology.
[0052] figure 2 It shows a flowchart of a monitoring method applied to an intelligent simulation indoor skiing safety system of the present invention.
[0053] Such as figure 2 As shown, the present invention also provides an intelligent simulation indoor skiing safety monitoring method, including the following steps:
[0054] The ultrasonic distance measuring sensor is arranged around the training suit of the student for obstacle detection, the ultrasonic distance measuring sensor detects the distance between the student and the obstacle during training, and the distance collected by the plurality of ultrasonic distance measuring sensors Upload the obstacle distance to the central processing system;
[0055] A plurality of the laser sensors are arranged around the ski machine, emit lasers to sense the physical changes of the students, and upload the laser signals to the central processing system;
[0056] The infrared thermal imaging panoramic scanner is set on the side of the ski machine to perform thermal imaging scans of the students, monitor the real-time changes of the students' status, and send the collected infrared thermal imaging images to the central processing system;
[0057] The gyroscope is set on the bottom of the ski machine to monitor the changes in the center of gravity of the trainees during training, and upload the center of gravity data to the central processing system;
[0058] The central processing system judges according to the distance information collected by the ultrasonic distance measuring sensor against the distance safety threshold. When the distance between the trainee and the obstacle is less than the safety threshold during training, the central processing system issues an instruction to make the alarm The system issues a voice alarm and stops the ski machine;
[0059] The central processing system judges the student's body posture information based on the infrared thermal imaging image collected by the infrared thermal imaging panoramic scanner and combined with the laser signal change collected by the laser sensor, and determines whether to trigger the alarm system according to the body posture information; The body posture information includes two states: a safe training posture and a dangerous training posture. When it is judged as a dangerous training posture, the central processing system issues an instruction to cause the alarm system to issue a voice alarm and stop the ski machine;
[0060] The central processing system compares the data of the center of gravity value collected by the gyroscope with the preset safety threshold range. When it is detected in real time that the center of gravity value of the student deviates from the safety threshold range, the central processing system determines that the student is in In the falling state, the central processing system will issue a control command to make the alarm system issue a voice alarm and stop the ski machine, and at the same time send an alarm message to the mobile phone of the staff on site, so that the staff immediately rush to the place where the alarm occurred The ski machine office provides assistance to students.
[0061] What needs to be explained is that the ultrasonic distance measuring sensor used is CM01-BEF1501, power supply voltage: 12V/24V DC, detection distance: 1.0-5.0 meters (0.3*0.3 meters flat target), blind zone: 0.15-0.35 meters, Repeatability: 0.5% or 2mm, sound beam angle: 10-15 0 , Output: digital signal: RS232/RS485, analog signal: 4-20MA/0-5V/0-10V, switch signal: PNP or NPN, choose one of the above output methods, distance setting and calibration method: button/display Teaching setting, output interface: M12 aviation plug or direct lead (5 core), allowable length of sensor output line: <50 meters, shell material: 1) main body: stainless steel, 2) sensor head: ABS engineering plastic, protection level: (sensor front) IP67, working temperature: 20-70 degrees;
[0062] CM01-BEF1501 is a BEF series ultrasonic distance sensor.

[0075] The primary training, intermediate training, and advanced training are divided according to the training time that the trainee has obtained;
[0076] The free training module is used for trainees to select individual training items.
[0077] What needs to be explained is that the evaluation scores of students who have obtained training time for primary training, intermediate training and advanced training are higher than those of zero-based students (that is, students who have not obtained training time).
[0078] It needs to be explained that the difficulty setting of free training content is relatively high, and permissions are only open to students who have a certain amount of training hours.
[0079] In this embodiment, a student information big data center is set up in the central processing system, which can record information filtered by the processing center, such as student’s learning situation: the student’s skiing learning in this class, the student’s periodic learning status, and different ages.
