[0002] Long-distance running requires athletes to run multiple laps around the track. During long-distance running, athletes need to complete a specified number of laps. When long-distance running is in progress, due to the large number of athletes, and after the start, athletes usually gather on the innermost lane to run, and there may also be a situation where faster athletes overtake slower athletes. Therefore, when the referee measures the number of laps of each athlete in a handwritten form, the workload is relatively large, and errors are likely to occur, ultimately leading to errors in the long-distance running results, affecting the competition or training performance. At the same time, the lap counting paper cannot be reused, which causes a certain degree of waste of resources to a certain extent.

[0003] Therefore, it is necessary to provide a long-distance running lap counting device, enabling the referee to quickly measure the number of laps completed by the athletes, reducing the difficulty of lap counting for the referee, and thus reducing the occurrence of incorrect lap counting by the referee.

Specific embodiments

[0024] The following further details the present utility model in conjunction with specific embodiments.

[0025] As Figure 1-6 shown, the long-distance running lap counting device includes a box body 1, a mushroom head button 2, a display screen 3, a U-shaped handle 4, a power switch 5, a single-chip microcomputer 6, and a matrix keyboard circuit 7. The button 2 is arranged on the panel of the box body 1, the display screen 3 is installed on the panel of the box body 1, both ends of the U-shaped handle 4 are hinged to both side walls of the box body 1 respectively, the power switch 5 is arranged on the side wall of the box body 1, the single-chip microcomputer 6 is fixedly installed inside the box body 1, the matrix keyboard circuit 7 is arranged inside the box body 1, a battery slot 8 is installed on the side wall of the box body 1, the battery slot 8 is electrically connected to the power switch 5, the power switch 5 is electrically connected to the single-chip microcomputer 6, the single-chip microcomputer 6 is electrically connected to the display screen 3 and the matrix keyboard circuit 7, and the mushroom head button 2 is connected to the matrix keyboard circuit 7 through pressing.

[0026] Before the start of a long-distance running race or training, the referee first lifts the device to the lap counting position through the U-shaped handle 4, then installs a battery in the battery slot 8, closes the battery slot 8, turns on the power switch 5, and the device is powered on. The referee waits at the lap counting position for the athlete to pass by. When the athlete passes by the lap counting position, the referee presses the corresponding mushroom head button 2 for lap counting. After a certain mushroom head button 2 is pressed, the corresponding matrix keyboard circuit 7 is turned on, and the signal is transmitted to the single-chip microcomputer 6. After the single-chip microcomputer 6 processes the signal, the signal is transmitted to the display screen 3, and the display screen 3 displays the current athlete number and the number of completed laps, thus completing one lap counting. Subsequently, when the athlete passes by the lap counting position again, the referee presses the mushroom head button 2 again for lap counting, and the display result on the display screen 3 is updated, thus completing the long-distance running lap counting.

[0027] The U-shaped handle 4 is a telescopic structure. A handle slot 9 is provided on the front side of the box body 1, and a removal slot 10 is provided at the edge of the handle slot 9.

[0028] When it is necessary to lift and move the device, insert a finger into the removal slot 10, then pinch the U-shaped handle 4, and pull the U-shaped handle 4 out of the handle slot 9, so that the device can be lifted and moved through the U-shaped handle 4. When the device is in the lap counting position, push the U-shaped handle 4 into the handle slot 9. On the one hand, the U-shaped handle 4 is in a fixed state to prevent unnecessary rotation of the U-shaped handle. At the same time, the U-shaped handle 4 is received in the handle slot 9, which also prevents other items placed around the device from being knocked down by the protruding U-shaped handle 4.

[0029] The mushroom head button 2 includes a number button group 201, a lap adding button 202, a lap subtracting button 203, an F1 function button 204, an F2 function button 205, and a reset button 206. Digital numbers are printed on the number button group 201, the symbol \"+\" is printed on the lap adding button 202, the symbol \"-\" is printed on the lap subtracting button 203, the symbol \"F1\" is printed on the F1 function button 204, the symbol \"F2\" is printed on the F2 function button, and the word \"Reset\" is printed on the reset button 206.

[0030] When an athlete passes through the lap counting position, the referee first presses the button corresponding to the number on the number button group 201. For example, if the athlete's number is No. 1, the referee presses the No. 1 button, and the number \"1\" on the display screen 3 is framed. Then the referee presses the lap adding button 202, and on the display screen 3, the number of laps after the number \"1\" is increased by 1. If the athlete has completed the 4th lap at this time, the number of laps changes from 3 to 4. If the referee makes a wrong operation, for example, after pressing the button corresponding to the number, accidentally presses the lap adding button 202 twice and counts one more lap, then one lap needs to be subtracted. At this time, the number button pressed is correct, that is, the corresponding number button is still selected, then the referee directly presses the lap subtracting button 203, and the lap number display is reduced by one lap. If the referee's wrong operation is pressing the wrong number button, the correct number button needs to be pressed first, and after selecting the correct number, the lap adding or subtracting operation is performed. Pressing the reset button 206 can clear the current display content on the display screen 3 and start lap counting again. The F1 function button and the F2 function button can set the functions of the device, such as setting the display time or the brightness of the display screen.

[0031] The digital numbers printed on the number button group 201 can be printed with different numbers according to actual needs. For example, they can be 1, 2,..., 30, or they can be 101, 102,..., 1030.

[0032] The first row of digital numbers in the number button group 201 is red, the middle row of digital numbers is blue, and the last row of digital numbers is green, where the first row is the row of the number button group 201 closest to the display screen 3, and the last row is the row of the number button group 201 farthest from the display screen 3.

[0033] The digital numbers are distinguished by colors, which can reduce the time for the referee to determine the corresponding number button, and further enhance the distinguishability between different number buttons, reducing the probability of misoperation. For example, the athlete number passing through the lap counting device is No. 18, and the number "18" printed on the number button is blue. Then the referee only needs to find the No. 18 number button within the range of blue digital numbers and press it, instead of searching for the No. 18 number button in all the number button groups 201.

[0034] The model of the single-chip microcomputer 6 is stc12c5410.

[0035] The long-distance lap counting device is powered by a 5V DC power supply.

[0036] The device is powered by a battery and does not need to be plugged into a wired power supply, which is convenient for the device to move, and its installation location is not affected by the power supply.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
