[0045] Embodiment 2:

[0046] The difference between Example 2 and Example 1 is that it also includes VR glasses, and the surfboard is an electronic surfboard.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, the present invention discloses a VR simulation surfing system including the system of embodiment 1, and also including VR glasses, wherein the VR glasses are wirelessly connected to and communicate with a computer; the surfboard is an electronic surfboard, and the electronic surfboard is wirelessly connected to and communicates with the computer.

[0049] During the experience, when the surfboard is moving and the user needs to maintain balance, the feet will generate different pressure differences on the resistance film layer 8. At this time, the electronic gyroscope 9 will record the balance state at this moment and determine whether the control fails.

[0050] Embodiment 3:

[0051] The difference between Example 3 and Example 1 is that the flexible cable parallel robot is a three-flexible cable parallel robot, the number of the flexible cable transmission units is three, the three parallel flexible cable transmission units form a three-flexible cable parallel transmission unit, and the three flexible cables are evenly distributed around the periphery of the surfboard.

[0052] The inventive concept of this application:

[0053] Surfing is a sport on the crest of waves, and existing ground-based surfing simulation devices cannot achieve the large-scale up, down, left, and right position changes required for surfing. The interconnected flexible cable parallel robot and surfboard in the present invention solve this technical problem.

[0054] Meanwhile, the current surfing simulation device does not provide a measurement of the surfer's posture balance, and therefore cannot provide a complete evaluation of the motion parameters. The flexible cable parallel robot and sensor surfboard of the present invention provide a solution to this problem.

[0055] The present invention is based on the soft-cable parallel robot technology and utilizes a platform equipped with sensors controlled by soft-cable traction to realize the experience of simulated surfing in the air.

[0056] The present invention adopts a combination of a flexible cable parallel robot and a sensor platform. The sensor platform is suspended in the air with a flexible cable, so that the flexibility and multi-dimensional change simulation of the waves can be realized. The sensor platform is provided with a sensor module and a communication module for measuring the displacement of the center of gravity on a universal surfboard, which can measure the posture of the experiencer and upload it to the main controller, so as to evaluate the balance of the experiencer and determine whether the game fails.

[0057] Technical solution description:

[0058] 1. The main feature of the present invention is the combination of a flexible cable parallel robot and a sensor surfboard.

[0059] 2. If Figure 2 As shown, the flexible cable parallel robot consists of four columns, four flexible cables (steel wires or fiber materials), four motor acceleration and reduction gears, and a rope drum (the number of columns and motors here can also be three, five, or six and the number of motors can also be three, five, or six).

[0060] 3. One end of the flexible cable is connected to the periphery of the surfboard, and the other end is connected to the rope drum, which is connected to the reducer shaft.

[0061] 4. The surfboard is equipped with sensors that can measure whether the user's posture is balanced.

[0062] 5. A safety cable is installed above the entire facility.

[0063] 6. The specific steps of the present invention include:

[0064] 6.1 The experiencer stands on the surfboard, puts on (or does not put on) VR glasses, fastens the safety sling, and is prompted to start the experience game.

[0065] 6.2 The simulation game software begins to form a virtual wave image and actual physical parameters. Driven by the control motor, the soft rope pulls the surfboard to move with the "waves".

[0066] 6.3 The user tries to keep balance. The electronic surfboard is equipped with an electronic gyroscope and a pressure sensor. When the user's center of gravity exceeds the physical center of gravity of the surfboard, the game prompts that the surfing has failed and the user falls into the water.

[0067] After this application was run confidentially for a period of time, the on-site technicians reported that the benefits were:

[0068] In the present invention, the flexible rope of the flexible rope parallel robot lifts up the surfboard, which simulates the motion of surfing more realistically, realizes the flexible change characteristics and the characteristic of floating on the "water surface" of surfing, solves the flexible experience and multi-dimensional motion changes of surfing, and can evaluate the balance state of the experiencer, greatly improving the realism of the surfing experience.

[0069] The electronic gyroscope, pressure sensor and resistance film layer of the electronic surfboard together constitute the measurement of the balance state of the surfboard and the control strength of the surfboard by the person. The electronic gyroscope and pressure sensor indicate the current state of the surfboard; the parameter difference on the resistance film layer indicates the control effort of the surfboard by the person.
