Description

Technical Field

[0001] The present invention relates to a skating finish line detection technology, and in particular to an ice skating finish line system based on wireless transmission of photoelectric signals through an ice surface. By arranging an optical signal transmitter in an ice skating finish line detector and an optical signal receiver in an ice layer to wirelessly transmit the skating finish line signal through the ice surface, the ice surface opening required for the external lead-out cable of the finish line electrical signal in the existing ice skating finish line detector and the pre-buried double-end lead-out cable in the ice layer can be eliminated, thereby meeting the requirement for synchronous transmission of the skating finish line signal and avoiding the risk of errors that may be introduced by damaging the ice surface and temporary manual wiring when deploying the equipment. Background Art

[0002] Ice skating is an important winter sport, and more and more people love it. Ice skating can exercise and enhance the body's balance, coordination, and flexibility, and can effectively exercise the lower limb strength. In sports competitions, speed skating is the oldest and most widely carried out event in skating. In speed skating competitions, it is necessary to set a sprint line and conduct a line detection for the first athlete to reach the finish line, which requires considering the characteristics of the ice rink as a special sports venue. For example, in existing formal skating events, line detectors and line reflective devices are used for line detection of skaters. Reference Figure 2 As shown, when deploying the finish line detection equipment, it is necessary to arrange the skating finish line detector 5 on the ice surface, and to arrange the reflective device 3 for finish line detection opposite the skating finish line detector. When the athlete crosses the finish line, the ice skate blocks the light signal emitted by the internal circuit of the skating finish line detector 5, namely, the circuit module 6, namely, the light ray 9 to be rushed out. The circuit module 6 inside the skating finish line detector 5 detects the finish line signal whose light is blocked, and transmits the finish line signal back to the signal processing unit through the external lead-out cable 7 of the finish line electrical signal and the pre-buried double-end lead-out cable 2. However, in each competition, the referee needs to smash a gap in the ice surface, namely, to chisel an opening 8 in the ice surface, take out the pre-buried cable, namely, the connector of the pre-buried double-end lead-out cable 2, and connect it to the lead-out cable of the skating finish line detector 5 (namely, the external lead-out cable 7 of the finish line electrical signal), so that the skating finish line detector can work normally. This method requires destroying the ice surface, and the connection method is very inconvenient. The inventor believes that if an optical signal transmitter is provided in the ice skating finish line detector and an optical signal receiver is provided in the ice layer to wirelessly transmit the ice skating finish line signal through the ice surface, the ice surface opening required for the external lead-out cable of the finish line electrical signal in the existing ice skating finish line detector and the pre-buried double-end lead-out cable in the ice layer can be eliminated, thereby meeting the requirement of synchronous transmission of the ice skating finish line signal and avoiding the risk of damage to the ice surface and possible error introduced by temporary manual wiring when deploying the equipment. In view of this, the inventor completed the present invention. Summary of the invention

[0003] In view of the defects or shortcomings existing in the prior art, the present invention provides an ice skating finish line system based on wireless transmission of photoelectric signals through the ice surface. By setting an optical signal transmitter in the ice skating finish line detector and an optical signal receiver in the ice layer to wirelessly transmit the ice skating finish line signal through the ice surface, it is possible to eliminate the ice surface opening required for the external lead-out cable of the finish line electrical signal in the existing ice skating finish line detector and the pre-buried double-end lead-out cable in the ice layer, thereby meeting the requirements for synchronous transmission of ice skating finish line signals and avoiding the risk of errors that may be introduced by damaging the ice surface and artificial temporary wiring when deploying the equipment.

DETAILED DESCRIPTION

[0014] Below is the attached figure ( Figure 1-Figure 2 ) to illustrate the present invention.

[0015] Figure 1 The present invention is a schematic diagram of the structure of an ice skating finishing system based on wireless transmission of photoelectric signals through an ice surface.

[0016] Figure 2 The present invention is a schematic diagram of the structure of a skating finishing system using wired transmission in the prior art. Figure 1 and Figure 2 Compared with the above, the structure is significantly different. For example, Figure 1 A new channel for the crossing optical signal 11 is set up in the middle, and an optical signal transmitter 13 and an optical signal receiver 14 are introduced to form the crossing optical signal 11. Figure 2 The external lead-out cable 7 of the electric signal of the punch line is changed to Figure 1 The internal transmission cable 17 of the electric signal of the punch line will Figure 2 The embedded double-ended lead-out cable 2 in the Figure 1 Pre-buried single-ended lead cable 12. Reference Figure 1As shown, an ice skating finish line system based on wireless transmission of photoelectric signals through the ice surface includes an ice skating finish line detector 5 and a reflecting device 3 which are arranged in pairs on the upper surface of the ice layer 1 to generate a finish line (i.e., light is used as the finish line, such as an outgoing light 9 to be rushed and a reflected light 10 to be rushed, etc.) between the two. An optical signal transmitter 13 is arranged in the ice skating finish line detector 5. The electrical signal receiving end of the optical signal transmitter 13 is connected to the circuit module 6 in the ice skating finish line detector 5 through an internal finish line electrical signal transmission cable 17. An optical signal receiver 14 is arranged in the ice layer 1. The transmitting end of the optical signal transmitter 13 transmits the finish line optical signal 11 triggered by the first finish line electrical signal to the receiving end of the optical signal receiver 14 through the ice surface. The output end of the optical signal receiver 14 outputs the second finish line electrical signal triggered by the finish line optical signal 11 through a pre-buried single-ended lead-out cable 12 in the ice layer 1.

[0017] The reflecting device 3 includes a reflecting surface 4, and the reflecting surface 4 faces the ice skating finish detector 5. The light to be struck includes an outgoing light 9 to be struck that reaches the reflecting surface 4 from the circuit module 6, and a reflected light 10 to be struck that reaches the circuit module 6 from the reflecting surface 4. Figure 1 The output end of the optical signal receiver 14 is connected to the output end of the pre-buried single-ended lead-out cable 12 ( Figure 1 The optical signal transmitter 13 is provided with a first condensing lens 15 at the transmitting end. The optical signal receiver 14 is provided with a second condensing lens 16 at the receiving end.

[0018] The present invention aims to solve the problem in the actual use of the ice skating finish line detector (in each game, the referee needs to smash the ice surface to make a gap, such as Figure 2 The ice surface in the ice is chiseled with an opening 8, and the pre-buried cable, i.e., the connector of the pre-buried double-end lead-out cable 2, is taken out, and connected with the lead-out cable of the ice skating finish line detector 5, i.e., the external lead-out cable 7 of the finish line electrical signal, so that the ice skating finish line detector can work normally. This method requires destroying the ice surface, and the connection method is very inconvenient), and a method of wireless transmission through the ice surface based on photoelectric signals is proposed.

[0019] The main features of the present invention are as follows: 1. Information is wirelessly transmitted through the ice surface using a photoelectric method. 2. During the photoelectric transmission process, in order to improve the photoelectric transmission efficiency, a first focusing lens 15 is placed on the optical signal transmitter 13. 3. During the photoelectric transmission process, in order to improve the light receiving sensitivity, a second focusing lens 16 is placed on the optical signal receiver 14. 4. When the skating finish line detector 5 detects the athlete's finish line signal, it immediately transmits the finish line optical signal 11 to the ice surface. 5. The optical signal receiver 14 is pre-buried under the ice surface. After detecting the optical signal emitted by the optical signal transmitter 13 used for optical transmission inside the finish line detector, it is converted into an electrical signal, and the signal is transmitted back to the signal processing unit through the cable pre-buried under the ice, i.e., the pre-buried single-ended lead-out cable 12.

[0020] The advantages of the present invention are as follows: 1. When deploying the equipment during the competition, there is no need to damage the ice surface, and the ice surface maintenance is convenient. 2. When deploying the equipment, no additional connection cables are required, and the deployment is convenient and fast, avoiding the risk of errors introduced by manual wiring. 3. The optical signal transmission delay is low, meeting the requirements of synchronous transmission of the finish line signal.
