[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1-6 As shown, a track and field competition finish line determination device according to an embodiment of this application includes:

[0027] The camera assembly 100 includes a camera protective housing 110 and a camera 120. The camera 120 is installed inside the camera protective housing 110, and a connector 130 is provided at the bottom of the camera protective housing 110.

[0028] The support assembly 200 includes a connecting bracket 210, a support plate 220, an adjusting column 230, and a support base 240. One end of the connecting bracket 210 is fixedly connected to the support plate 220, and the other end of the connecting bracket 210 is fixed to the camera protective housing 110 via a connector 130. The output end of the adjusting column 230 is fixedly connected to the support plate 220, and the other end of the adjusting column 230 is fixedly connected to the support base 240. The camera 120 is fixed to the support assembly 200 via the connector 130, facilitating the movement of the camera 120 and reducing environmental requirements. During use, the height of the camera 120 is adjusted via the adjusting column 230 to a suitable height, allowing the camera to determine the finish line and improving the accuracy of finish line determination. This solves the problems of current technologies, which require very high environmental conditions for the work site, are difficult to move, and are difficult to adjust the height, causing inconvenience in children's track and field competitions.

[0029] like Figure 2 As shown, slide rods 250 are fixedly connected between the four corners of the support plate 220 and the support base 240. When the support plate 220 is adjusted up and down, the slide rods 250 adjust accordingly, thereby improving the stability of the overall device. A configuration block 260 is inserted into the support base 240. The configuration block 260 is used to adjust the center, thereby increasing the stability of the device. A locking caster 270 is provided at the bottom of the support base 240. The locking caster 270 facilitates the movement of the device. A handle 140 is fixedly connected to the top of the camera protective housing 110. The handle 140 is used to lift the camera protective housing 110 when installing or removing it.

[0030] like Figures 3 to 5As shown, the camera 120 includes a camera body 121 and an infrared thermal imaging detector 122. The camera body 121 and the infrared thermal imaging detector 122 are sequentially fixedly connected to the camera protective housing 110. A microprocessor is installed inside the camera body 121. The microprocessor is a DSP digital signal processor. The camera body 121 is a high-speed camera, and the infrared thermal imaging detector 122 is an infrared human image detection transmitting module. This transmitting module is located at a relatively long distance from the finish line to detect in advance whether an athlete is about to cross the finish line. A red-green indicator light 123 is provided on one side of the infrared thermal imaging detector 122. The red-green indicator light 123 is used to indicate the working status of the camera body 121 and the infrared thermal imaging detector 122. It is green when working and red when in standby mode. When an athlete enters the detection range of the infrared thermal imaging detector 122, the red-green indicator light 123 turns green. At this time, the camera body 121 starts up and records at high speed. Meanwhile, the infrared thermal imaging detector 122 continues to work, detecting the athlete's status when crossing the finish line. The red-green indicator light 123 turns red when the athlete leaves the detection range of the infrared thermal imaging detector 122. At the same time, the camera body 121 and the infrared thermal imaging detector 122 enter standby mode. By using the camera body 121 and the infrared thermal imaging detector 122 together to detect the athlete's crossing of the finish line, the accuracy of the finish line determination is improved. Furthermore, the system automatically enters standby mode when the athlete has not crossed the finish line and automatically starts detection when the athlete crosses the finish line, thus saving camera resources and improving detection efficiency.

[0031] like Figure 6As shown, the connecting bracket 210 includes a bracket body 211 and a support plate 212. The bracket body 211 is symmetrically connected to the support plate 220, and the support plate 212 is fixedly connected to the bracket body 211. Multiple triangular structures are formed by the bracket body 211 and the support plate 212, thereby improving the camera's image stability. The connector 130 includes a connecting block 131 and a bolt 132. The connecting block 131 is fixedly connected to the camera protective housing 110. A connecting groove 133 is provided on the support plate 212, and the connecting block 131 is fixedly connected to the connecting groove 133 by the bolt 132. By rotating the bolt 132, the connecting block 131 can be fixed or removed from the connecting groove 133, thereby completing the installation or removal of the camera protective housing 110, facilitating the quick installation or removal of the camera 120. The adjusting column 230 includes a support column 231, an adjusting column body 232, and a fixing pin 233. The support column 231 is fixedly connected to the support base 240. The adjusting column body 232 is inserted into the support column 231. Adjusting holes 234 are correspondingly opened on the support column 231 and the adjusting column body 232, and the adjusting holes 234 are evenly arranged vertically. The fixing pin 233 is inserted into the adjusting hole 234. By adjusting the sleeve length of the adjusting column body 232 in the support column 231, and then using the fixing pin 233 to insert into the adjusting hole 234, the adjusting column body 232 is fixed in the support column 231, thereby adjusting the height of the support plate 220. This allows for flexible adjustment of the height of the camera 120 according to the athlete's height, preventing the camera from being unable to clearly capture the athlete crossing the finish line and affecting the judgment.

[0032] In summary, the working principle of the track and field finish line determination device according to this utility model embodiment is as follows: By rotating the bolt 132, the connecting block 131 is fixed in the connecting groove 133, thereby fixing the camera 120 on the support assembly 200. This facilitates the movement of the camera 120 and has low requirements for the operating environment. During use, by adjusting the sleeve length of the adjusting column 232 in the support column 231, and then using the fixing pin 233 to be inserted into the adjusting hole 234, the adjusting column 232 is fixed in the support column 231, thereby adjusting the height of the support plate 220. This allows for flexible adjustment of the height of the camera 120 according to the athlete's height, which is beneficial for determining the finish line in children's track and field competitions. When an athlete enters the detection range of the infrared thermal imaging detector 122 during the competition, a red and green indicator is displayed. When light 123 turns green, camera body 121 starts recording at high speed, while infrared thermal imaging detector 122 continues to work, detecting the athlete's status when crossing the finish line. The process continues until the athlete leaves the detection range of infrared thermal imaging detector 122, at which point the red-green indicator light 123 turns red. Simultaneously, camera body 121 and infrared thermal imaging detector 122 enter standby mode. By using both camera body 121 and infrared thermal imaging detector 122 to jointly detect the athlete's crossing of the finish line, the accuracy of finish line determination is improved. Furthermore, the system automatically enters standby mode before crossing the finish line and automatically starts detection upon crossing, thus saving camera resources and improving detection efficiency. This solves the problems of current technology, which requires very high environmental conditions for the working site, is difficult to move, and is difficult to adjust the height, causing inconvenience in children's track and field competitions.
