S110. Send the score to the display terminal.

It should be noted that a switch sensor can be set under the snow blanket of the simulated snow machine, and the position of the switch sensor can be changed by adjusting the device. Proximity switch sensor is a general term for sensors that replace the contact detection methods such as limit switches, and the purpose is to detect without touching the detection object. The user's trajectory, through which the user's game score can be obtained. Due to the different usage and exercise habits of different game modes and different users, the position of the switch sensor will change. Therefore, the location information and collected data of each switch sensor are first obtained during the game. The collected data It can be a signal of 0 and 1, 0 means that there is no user's movement signal, that is, no user passes the switch sensor; 1 means that there is a user's movement signal, which means that the user passes this switch sensor. Then, according to the position information of the switch sensor and the collected data, the running track of the user is analyzed. The user's running trajectory can be obtained by analyzing the signals obtained by the switch sensors at different positions under the snow blanket and the time point of data collection. Then, the scoring rules of the game are obtained. The scoring rules match the running track of the user. If the running track of the user matches the scoring rules, the score is higher. The running track is analyzed according to the scoring rules of the game to obtain the score of the game; and the score is sent to the display terminal.

The display terminal of the present invention can be a display system, which is connected to the competition system and can display the competition tasks through video equipment such as projectors, TVs, notebooks, ipads, etc. in real time. It can be connected with the video device, linked with the information processing center and the data center, and can mobilize the local or multiple event interaction data in real time, and the comprehensive data of the data center (such as real-time data, staged event data, regional event data, etc.) Information is displayed through video equipment.

It should be noted that the present invention also includes a data center, which will record the event information screened by the information processing center, and at the same time record the entry information of the contestants: age, gender, study information, area to which they belong, etc., which can be generated according to the needs of data analysis. Various data reports, such as current or previous competition data reports, competition data reports in different regions, and comprehensive competition data reports for contestants. It is worth mentioning that in addition to collecting comprehensive event data that is scarce in the ski industry, the data center can also combine information such as big data and individual player competition results to provide more targeted data analysis and learning for each contestant.

The game scoring mode is a mode of timing counting or constant timing.

It should be noted that the present invention can perform scoring in different ways, and the specific scoring mode of the game is the mode of timing counting or constant timing. The timing counting mode may be to count the number of devices or the number of actions that the user passes through within a certain period of time for scoring. It can be that the larger the number, the higher the score, or the smaller the number, the higher the score, which can be set by those skilled in the art according to actual needs. For example, it can be the number of piles that the user circles. In this mode, the more times the user circles piles within a certain period of time, the higher the score will be. The fixed number timing method may be that after the user passes a fixed number of devices or performs a fixed number of actions, time statistics are performed, and scores are performed according to the time. For example, if the user spends 50 seconds after passing the pile 10 times, the converted score is 60 points; after the user passes the pile 10 times and the user spends 40 seconds, the converted score is 80 points.

According to the embodiment of the present invention, in the present invention, the user's position, the coordinates of the sensor, the user's driving trajectory, and the slope of the snow blanket are all recorded in the form of three-dimensional coordinates. The three-dimensional coordinates can be established through the three axes of xyz.

It should be noted that a three-dimensional coordinate system is first established, and a unified xyz coordinate can be established in a specified area. Then, according to the data, position, and angle information of each sensor, the user's position can be calculated and mapped to the coordinate system to obtain the corresponding coordinate value. Since the time point information is also obtained, the motion trajectory can be generated through the coordinate value and the time point. Through the motion trajectory, motion state data can be obtained. The motion state data may include information such as the user's cadence, speed, and orientation.

According to the embodiment of the present invention, it also includes:

Get game mode information;

For example, in the large loopback project, the switch sensors can be arranged in an approximately arc-shaped arrangement. The layout information is sent to the adjustment device, and the adjustment device can adjust the position of each switch sensor according to the layout information.

For example, two longitudinal rows of sensor sensing groups with a distance of 20cm between each proximity switch sensor are arranged under the snow blanket. The straight line formed by each group of proximity switch sensors is parallel to the snow blanket, and the two rows of sensor sensing groups are listed on the left and right sides of the snow blanket. On both sides; and a fixed serial number is programmed for each proximity switch sensor, so as to set up various competition items in which sensors with different numbers are arranged in an orderly manner and the distance between the two groups of sensors on the left and right sides is fixed.

It should be noted that the number of changes of each switch sensor within a preset time period is determined, wherein the preset time period may be 0.5 seconds or 1 second, mainly to obtain whether the user's feet have passed the switch sensor. If the number of changes is 2, it means that the user's left or right foot has passed through the switch sensor, rather than a single foot. Only by bypassing this switch sensor can it be considered as a pass in a flag or pile race.

Proximity switch sensor, when the contestant bypasses the displacement coordinates of the designated proximity switch, the proximity switch sensor will automatically transmit the contestant's detour time to the information processing center in real time.

The standard trajectory is the preset action trajectory, and then the user's running trajectory is compared with the obtained standard trajectory. Compare and analyze the coincidence of the trajectories. If the degree of coincidence is high, it means that the user's movement trajectory and method in the simulated snow machine are more consistent with the preset standard trajectory and method, and the user's movement can be considered to be relatively standard; if the degree of coincidence is low, it means that the user's movement is not standard. Action guidance suggestions and video data can be generated in this case. The video data may include information such as the user's non-standard action marks and standard action instructions, so as to facilitate the user to check his own action deficiencies and correct actions through guidance suggestions.
