6 is a block diagram illustrating an example of a method for storing a ball using a sports game recording device according to an embodiment of the present invention. Referring to FIGS. 1 to 4 and FIG. 6 together, the ball storage method using the sports game recording device 10 includes a switch-on step (S10), a starting temperature measurement step (S20), and a heater operation step ( S30), an intermediate temperature measurement step (S40), an intermediate temperature measurement count accumulation step (S50), a unit time lapse step (S60), and a heater operation stop step (S70).

The switch-on step (S10) is a step of supplying electric energy to operate the controller by pressing the power switch 40 in a state where the ball is accommodated in the inner space 13 and the cap 20 is closed. The starting temperature measuring step (S20) is a step of measuring the temperature of the container, that is, the inner space 13 of the cylinder 12, with the temperature sensor 35. The heater operating step (S30) is a step of operating the heater 33 when the temperature measured in the starting temperature measuring step (S20) is lower than a preset minimum reference temperature. As described above, in the sports event filming device 10 that keeps tennis balls warm, the minimum reference temperature may be 15°C. At the same time that the heater 33 operates, the red LED of the lamp 53 emits light to notify the user that the ball accommodated in the inner space 13 is being heated.

The intermediate temperature measuring step (S40) is a step of measuring the temperature of the inner space 13 with the temperature sensor 35 after the heater operating step (S30). The step of accumulating the number of measurements of the intermediate temperature (S50) is performed after the step of operating the heater (S30) when the temperature measured in the step of measuring the intermediate temperature (S40) is lower than or equal to the highest reference temperature preset as a temperature higher than the minimum reference temperature. This step is to cumulatively add up the number of measured intermediate temperatures. The unit time lapse step (S60) is a step in which time elapses by a preset unit time when the cumulative number of intermediate temperature measurements accumulated and summed in the step (S50) is less than the preset reference number N times. . For example, the reference number of times N may be 60, and the unit time may be 1 second. After the unit time lapse step (S60), that is, after the unit time has elapsed, the intermediate temperature measuring step (S40) is repeatedly performed.

The heater operation stop step (S70) is a step of stopping the operation of the heater 33 when the temperature measured in the intermediate temperature measurement step (S40) is higher than the maximum reference temperature. As soon as the operation of the heater 33 is stopped, the red LED of the lamp 53 is turned off and the blue LED emits light to inform the user that the heating of the ball has been completed. Meanwhile, the operation of the heater 33 may be stopped even when the accumulated number of intermediate temperature measurements accumulated and summed in the step of accumulating the number of intermediate temperature measurements reaches the reference number N times. In addition, even when the temperature measured in the starting temperature measuring step ( S20 ) is higher than or equal to the minimum reference temperature, the operation of the heater 33 may be stopped. In this case, since the heater 33 has never been operated, it can be accurately said that the heater 33 is not operated.

On the other hand, the ball storage method using the sports game recording device 10 is not limited to the method shown in FIG. 6 and may be partially modified or added. For example, the step of accumulating the number of measurements of the intermediate temperature ( S50 ) may not be present. In this case, if the temperature measured in the intermediate temperature measuring step (S40) is lower than or equal to the maximum reference temperature, it proceeds to the unit time elapsed step (S60) and after a unit time elapses, the intermediate temperature measuring step (S40). ) is repeated.

In addition, after the heater operation stop step (S70), the number of intermediate temperature measurements is cumulatively summed, and if the cumulative summed number of intermediate temperature measurements is less than the preset reference number of N times, the time by the preset unit time has elapsed. After that, the intermediate temperature measuring step (S40), that is, the step of measuring the temperature of the inner space 13 with the temperature sensor 35 may be repeated.

The sporting event filming device 10 described above may be placed on a flat floor or a pedestal, and an application installed in the portable terminal 65 may be manipulated to capture a sports game and generate a video. Therefore, there is no need to continuously hold a video camera or smartphone, so there is no fatigue or difficulty in shooting, and the quality of the recorded video is also improved.

In addition, when the sports game recording device of the present invention is installed on the extension line of the boundaries (4, 6) of the stadium where the sports game is held and the camera unit 55 is operated to capture a video, the ball is captured along the boundary line (4, 6). 6), it is possible to accurately determine whether it corresponds to an IN that spans or falls within the boundary lines 4 and 6, or an OUT that goes outside the boundary line by closely examining the recorded video again. Therefore, it is possible to reduce judgment disputes in sports games of amateur club members, in which there is no separate referee. In particular, when a captured video is analyzed using artificial intelligence (AI), a result can be accurately determined without a person directly viewing the captured video.

In addition, since the sports game recording device 10 has a function of storing the balls used in sports games in the best performance state, there is no need to separately provide a ball storage box, and the performance and fun of sports games can be improved. It improves.
