Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-5 The technical solution of the present invention will be further illustrated through specific embodiments.

[0019] This invention provides a fully automatic intelligent scoring system for badminton, including a base 101, a platform plate 113 mounted on the base 101, and multiple pressure sensors arranged in a rectangular array between the platform plate 113 and the base 101 for monitoring the position of the athlete on the platform plate 113. A net 112 is fixed in the middle of the platform plate 113. Two support frames 102 are fixed on the base 101, and four parallel guide rods 104 are fixed between the two support frames 102. A following moving beam 138 is slidably mounted on the four guide rods 104. A first monitoring camera 107 and a second monitoring camera 110 are slidably mounted on the top and sides of the following moving beam 138, respectively. The second monitoring camera 110 is used to record the height information of the badminton shuttlecock, and the first monitoring camera 107 is used to record the planar coordinate information of the badminton shuttlecock. Four monitoring cameras 103 are fixed on the top of the two support frames 102 for recording the trajectory of the badminton shuttlecock. Two follower belts 111 are rotatably mounted on the base 101. These two follower belts 111 are synchronously driven by a drive shaft 114. The follower belts 111 drive the following moving beam 138 to slide on the guide slide rod 104. A first drive belt 106 and a second drive belt 109 are rotatably mounted on the top and sides of the following moving beam 138, respectively. The first drive belt 106 drives the first monitoring camera 107 to slide on the following moving beam 138, and the second drive belt 109 drives the second monitoring camera 110 to slide on the following moving beam 138. A first drive motor 105 for driving the first drive belt 106 and a second drive motor 108 for driving the second drive belt 109 are also fixed on the following moving beam 138. A gearbox 115 for driving the follower belts 111 is also embedded within the base 101. The output end of the gearbox 115 is connected to the follower belts 111 via a drive shaft 114. A support housing 116 is fixed to the lower surface of the base 101. A limiting collar 128 is rotatably mounted on the support housing 116. A linkage gear ring 126 is fixedly sleeved on the limiting collar 128. A linkage gear 124 is rotatably engaged with the support housing 116 on the side of the linkage gear ring 126. A reduction cylinder 123 is also fixed to the support housing 116. A reduction blade 121 is rotatably mounted inside the reduction cylinder 123. The reduction blade 121 and the linkage gear 124 are synchronously driven by a reduction shaft 125. A temperature-conducting plate 122 is fixedly sealed at the end of the reduction cylinder 123 away from the supporting outer shell 116, so that a sealed space is formed inside the reduction cylinder 123. A heat sink 119 is fixed on the temperature-conducting plate 122, and a cooling secondary plate 120 is arranged in contact between the heat sink 119 and the temperature-conducting plate 122. A follower drive motor 118 is fixedly mounted on the reduction cylinder 123 through a follower drive motor bracket 117, and a dial 127 is fixed on the output shaft of the follower drive motor 118.A drive turntable 129 is rotatably mounted on the inner side of the limiting collar 128. The drive turntable 129 is fixedly engaged with the input end of the gearbox 115. Two symmetrically arranged limiting frames 131 are fixedly mounted on the edge of the drive turntable 129. The limiting frames 131 slide with the inner wall of the limiting collar 128. A pressing block 132 is contacted on the inclined surface of the limiting frame 131. The pressing block 132 slides and rubs with the inner wall of the limiting collar 128. An actuating block 133 is also contacted between the pressing block 132 and the inclined surface of the limiting frame 131. A gap is provided between the actuating block 133 and the inclined surface of the limiting frame 131. All the actuating blocks 133 are fixed on the actuating disk 127. The limiting frame 131 is also provided with a leaf spring clearance groove 137. A leaf spring 136 is provided in the leaf spring clearance groove 137 to contact and cooperate with the two pressing blocks 132. The middle part of the leaf spring 136 is rotatably mounted on the leaf spring bracket 135. The leaf spring bracket 135 is fixed in the middle of the drive turntable 129. A stop block 130 is also fixed on the drive turntable 129. Springs 134 are fixed at both ends between the opposite surfaces of the stop block 130 and the leaf spring 136. The springs 134 and the leaf spring 136 are used to push the pressing block 132 to move toward the actuating block 133.

[0020] The working principle of the fully automatic badminton intelligent scoring system disclosed in this invention is as follows: When the athlete stands on the platform 113, the athlete will step on the pressure sensor at the corresponding position depending on the position of the athlete on the platform 113. The coordinate position of the athlete on the platform 113 can be determined by the pressure sensor array (when the athlete stands on the pressure sensor, the resistance value of the corresponding pressure sensor will change, and the position coordinate of each pressure sensor is determined, so the position of the athlete can be determined). The monitoring camera 103 tracks and records the trajectory of the badminton shuttlecock in real time during flight. This data serves as the control condition for the corresponding first drive motor 105 and second drive motor 108. The first drive motor 105 drives the first monitoring camera 107 to slide horizontally on the following moving beam 138 via the first transmission belt 106. The second drive motor 108 drives the second monitoring camera 110 to slide vertically on the following moving beam 138 via the second transmission belt 109. Simultaneously, the follow drive motor 118 is controlled. The output shaft of the follow drive motor 118 controls the follow moving beam 138 to slide rapidly on the guide slide bar 104 via the follow transmission belt 111. Its main purpose is to follow the direction of the badminton shuttlecock's movement. The first monitoring camera 107 and the second monitoring camera 110 are always aligned with the shuttlecock on the same vertical plane. The first monitoring camera 107 can record the plane coordinates of the shuttlecock, and the second monitoring camera 110 can record the height coordinates of the shuttlecock. The first monitoring camera 107 and the second monitoring camera 110 can record the spatial coordinates of the shuttlecock. The first drive motor 105 and the second drive motor 108 mainly control the first monitoring camera 107 and the second monitoring camera 110 to always be aligned with the shuttlecock, so as to improve the accuracy of the measured spatial coordinates of the shuttlecock, thereby facilitating the recording of the landing point of the shuttlecock and whether the shuttlecock contacts the net 112, and thus scoring the badminton match.

[0021] The shuttlecock moves very fast, so the sliding speed of the following moving beam 138 on the guide slide 104 also needs to be synchronized. The following moving beam 138 is located at the two ends of the guide slide 104. The speed of the following moving beam 138 needs to be reduced to 0. This process is the moment when the shuttlecock and the racket come into contact, which is the moment when the direction of the shuttlecock's movement changes. At this time, the direction of movement of the following moving beam 138 also needs to be changed. In order to ensure the service life of the overall equipment, a buffer needs to be placed at the position where the speed of the following moving beam 138 is reduced to 0. The specific method is as follows: the output shaft of the follow drive motor 118 drives the actuation disk 127 to rotate, the actuation disk 127 drives the actuation block 133 to rotate, the actuation block 133 drives the limiting frame 131 to rotate, the limiting frame 131 drives the drive turntable 129 to rotate, the drive turntable 129 drives the input end of the gearbox 115 to rotate, the output end of the gearbox 115 drives the follow transmission belt 111 to rotate, and then the follow transmission belt 111 drives the follow moving beam 138 to slide on the guide slide bar 104. During this process, one of the actuation blocks 133 will contact the inclined surface of the limiting frame 131, thereby directly... The limiting frame 131 is then moved, and the pressing block 132 in the limiting frame 131 is subjected to frictional force from the inner wall of the limiting collar 128. The direction of this frictional force causes the pressing block 132 to move away from the actuating block 133. At this time, the inclined surface of the limiting frame 131 and the limiting collar 128 will not compress the pressing block 132. On the contrary, the pressing block 132 in the limiting frame 131, which is symmetrical to it, will also move away from the inclined surface of the limiting frame 131 under the actuation of the actuating block 133, and will not be compressed by the limiting collar 128 and the inclined surface of the limiting frame 131.During the period when the speed of the following moving beam 138 decreases to 0, the following drive motor 118 needs to be stopped. During this process, the following moving beam 138, under the action of inertia, will drive the drive turntable 129 to rotate in the opposite direction. The rotation of the drive turntable 129 will drive the limiting frame 131 to rotate. The rotation of the limiting frame 131 will drive one of the pressing blocks 132 to move. At this time, no matter which direction the limiting frame 131 rotates, there will always be a pressing block 132 that experiences frictional force from the inner wall of the following moving beam 138 towards the inclined surface of the limiting frame 131 (because the limiting frame 131 is symmetrically arranged on the drive turntable 129). At this time, the pressing block 132 will be squeezed by the drive turntable 129 and the inclined surface of the limiting frame 131, thereby increasing the frictional force on the pressing block 132 until it is stuck between the limiting frame 131 and the limiting collar 128 (both pressing blocks 132 are...). The leaf spring 136 and spring 134 will maintain contact with the inclined surface of the limiting frame 131 and the inner wall of the limiting collar 128. The leaf spring 136 will deform under the elastic force of the spring 134, thereby actuating the squeezing block 132. At this time, the rotation of the drive turntable 129 will drive the limiting collar 128 to rotate through the limiting frame 131 and squeezing block 132. The rotation of the limiting collar 128 will drive the linkage gear ring 126 to rotate. The rotation of the linkage gear ring 126 will drive the linkage gear 124 to rotate. The linkage gear 124 will drive the reduction blade 121 to rotate through the reduction shaft 125. The reduction blade 121 will drive the liquid inside the reduction cylinder 123 to flow. The liquid will hinder the rotation of the reduction blade 121, and thus hinder the rotation of the drive turntable 129, thereby hindering the movement of the following moving beam 138, so that the following moving beam 138 is buffered during the period when the movement speed is reduced to 0. The buffering force is adjustable. Specifically, by controlling the power of the cooling secondary plate 120, a temperature difference is generated between the two sides of the cooling secondary plate 120. The cooling side contacts the temperature-conducting plate 122 (the temperature-conducting plate 122 has a certain degree of toughness and will deform slightly as the pressure inside the deceleration cylinder 123 changes), so that the temperature of the temperature-conducting plate 122 is lower. The temperature-conducting plate 122 lowers the temperature of the liquid inside the deceleration cylinder 123, increases the density of the liquid inside the deceleration cylinder 123, thereby increasing the resistance of the liquid to the rotation of the deceleration blade 121, and thus changing the buffering force.
