3. A ski assistance training system according to claim 2, wherein the multi-pose measurement module is performed by a scale arranged on the suspended structure during data acquisition, and the dynamic pose adjustment module is arranged with a display module within the visual range of the trainer for the trainer to observe the difference between the pose data itself and the reference data to provide the basis for pose change.
4. A ski training aid system as claimed in claim 2 wherein the pitch angle adjustment mechanism is driven and adjusted by a servo motor, and the multi-attitude measurement module comprises a pitch angle change module for controlling the sequence of the servo motor motion, the pitch angle change module being adapted to set the angle and dwell time of each pitch angle and to set whether a subsequent pitch angle is engaged or not.
5. A ski assistance training system as claimed in claim 4 wherein said multi-pose measurement module further comprises a display module for interacting with the trainer.
6. A ski assisted training system as claimed in any one of claims 1 to 5, wherein the central control module comprises an interactive module and a control module, the interactive module and the control module being connected by a bus to facilitate the transmission of commands from the interactive module to the control module and the uploading of status from the control module to the interactive module; the interaction module is used for man-machine interaction and displaying the given state of the instruction; the control module is used for judging according to the acquired attitude data and outputting a control signal or outputting the control signal according to an instruction of the interaction module.
7. A ski training aid system as claimed in claim 6, wherein a safety module is connected to the control module, the safety module being adapted to stop the entire ski training aid system in the event of an abnormal situation.
8. A skiing auxiliary training system as claimed in claim 7, wherein the safety guarantee module comprises a personnel safety guarantee module and an equipment safety guarantee module, and the personnel safety guarantee module is used for controlling the whole skiing auxiliary training system to stop running through a remote control device when an abnormality occurs in the training process of a trainer; the equipment safety guarantee module is used for stopping the whole skiing auxiliary training system when the collected pitch angle data and resistance data are compared with normal data or/and the collected posture data are compared with the normal data to be abnormal.
9. A ski assisted training system as claimed in claim 6, wherein the control module is connected to a mode selection module for selecting between a training mode and a maintenance mode, the training mode being a mode in which the suspension structure is placed in the wind tunnel flow field, and the maintenance mode being a mode in which the suspension structure is removed from the wind tunnel flow field.
10. The skiing assistance training system according to claim 6, wherein the control module is connected with an effectiveness guarantee module, the effectiveness guarantee module comprises a wind speed guarantee module and a posture and data acquisition linkage guarantee module, and the wind speed guarantee module is used for providing a specified wind speed when a trainer trains; the posture and data acquisition linkage guarantee module is used for reminding a trainer to keep a posture when data acquisition is needed, and reminding the trainer after data acquisition countdown is finished so as to relax.
