[0018] In a possible implementation, the controller calls the library function corresponding to the font, and drives the 8-shaped digital tube to display numbers through a data transmission line, which specifically includes the following steps: A1. The controller obtains the remaining time data of each quarter, the game score data, the number of quarters data and the corresponding numbers of the 24-second countdown data during the game; A2.

A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0025] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiment 1 See also Figure 1-2 As shown, an embodiment of the present application discloses a basketball game timer, including a display screen 1 for displaying basketball game time, a controller 2 for controlling the display screen 1 to display data, a remote control 3 for sending basketball game and 24-second countdown start and stop, and a voice broadcast module 4 for broadcasting the end of the game.

[0027] The display screen 1 includes a base plate 11 and a plurality of light strips 12 arranged on the base plate 11, each light strip 12 is provided with a positive terminal, a negative terminal and a data transmission terminal, the positive terminal of each light strip 12 is sequentially connected in series and finally electrically connected to the positive terminal of the power supply; the negative terminal of each light strip 12 is sequentially connected in series and then electrically connected to the negative terminal of the power supply; the data transmission terminal of each light strip 12 is connected in series and then electrically connected to the controller 2 through a data transmission line 5, and every seven light strips 12 surround to form an 8-shaped digital tube 6.

[0028] The voice broadcast module 4 is electrically connected to the controller 2, and the remote controller 3 is wirelessly connected to the controller 2. The controller 2 controls the light strip 12 to display the remaining time, the number of quarters and the 24-second countdown time of each quarter of the basketball game according to the signal received by the remote controller 3.

[0029] Only one data transmission line 5 can be used to control the lighting and extinguishing of all the light strips 12, so as to realize the display of the score of the entire basketball game. The circuit design is simple, and it is convenient to write the corresponding digital display program and to maintain it. The remote controller 3 can realize wireless remote control to update and display the score of the basketball game, which is easy to operate.

[0030] In this embodiment, the light strip 12 is a WS2812 light strip, the voice chip of the voice broadcast module 4 is a SYN6288 voice chip, and the single-chip microcomputer system in the controller 3 is an Arduino Nano. Of course, in the actual design process, other chips with similar functions can also be used.

[0031] The light strip 12 adopts the WS2812 type light strip, which is the light strip 12 of the prior art, and is convenient for querying the corresponding program writing rules and writing the corresponding program for displaying numbers. Of course, in actual use, other components with similar functions can also be used.

[0032] Among them, a plurality of light strips 12 at least form four 8-shaped digital tubes 61 for displaying the remaining time of each quarter, one 8-shaped digital tube 62 for displaying the number of quarters and two 8-shaped digital tubes 63 for displaying the countdown of 24 seconds; one 8-shaped digital tube 62 for the quarter number, four 8-shaped digital tubes 61 for the time of each quarter and two 8-shaped digital tubes for the countdown 63 are connected in series in sequence and then electrically connected to the controller 2 through a data transmission line 5.

[0033] The light strip is formed into a plurality of 8-shaped digital tubes 6, which can display the scores of the two teams, the number of game quarters and the 24-second countdown, so as to facilitate the observation of more information.

[0034] In order to improve the utilization rate of the light strip 12, the 8-shaped digital tube 61 in each section can also be used to display the game score.

[0035] In actual process, the display color can also be modified according to the illumination of the indoor environment, and this modification can be achieved through the remote controller 3.

[0036] Furthermore, in actual use, in addition to surrounding the 8-shaped digital tube 6, a circle of light strip 12 can also be wrapped around the outer edge of the entire display screen 1. This circle of light strip 12 can be displayed constantly, and the recognition of the display screen 1 can be improved through this circle of light strip 12.

[0037] Specifically, the circle of light strips 12 surrounding the outer edge of the display screen 1 is to be displayed constantly, so it can be another group of light strips 12 connected in series, and then communicated with the controller 2 through another data transmission line 5 to achieve constant light control; it can also be connected in series with the 8-shaped digital tube, and finally lit up through the same data transmission line 5 for communication control.

[0038] In this embodiment, the 8-shaped digital tube 6 includes a first horizontal light strip 121 located at the top, a second vertical light strip 122 located at the upper left, a third vertical light strip 123 located at the upper right, a fourth horizontal light strip 124 located in the middle, a fifth vertical light strip 125 located at the lower left, a sixth vertical light strip 126 located at the lower right, and a seventh horizontal light strip 127 located at the bottom.

[0039] The fourth horizontal light strip 124, the fifth vertical light strip 125, the seventh horizontal light strip 127, the sixth vertical light strip 126, the third vertical light strip 123, the first horizontal light strip 121 and the second vertical light strip 122 are connected in series in sequence; The fourth horizontal light strip 124 of the 8-shaped digital tube 6 is connected in series with the second vertical light strip 122 of the adjacent previous 8-shaped digital tube 6 , and the second vertical light strip 122 of the 8-shaped digital tube 6 is connected in series with the fourth horizontal light strip 124 of the adjacent next 8-shaped digital tube 6 .

[0040] By setting all 8-shaped digital tubes 6 to the same surround, the working principle and control method are different from the prior art, which is convenient for programming and control, and the circuit is very simple, which reduces the circuit connection and the probability of hardware problems. At the same time, it is easy to maintain and increase the service life.

[0041] Of course, in the actual circuit connection, because the positions of the section number 8-shaped digital tube 62, the section time 8-shaped digital tube 61 and the countdown 8-shaped digital tube 63 are limited (generally, the section time 8-shaped digital tube 61 is arranged on the top, and then the section number 8-shaped digital tube 62 is arranged on the right, and the countdown 8-shaped digital tube 63 is arranged below the section time 8-shaped digital tube 61), this leads to the use of the same surrounding method to form 8-shaped digital tubes 6. It is inconvenient to connect the upper and lower adjacent 8-shaped digital tubes 6. Therefore, other surrounding methods can also be used, for example, see Figure 3 The surround mode shown, of course, this also requires modification of the corresponding driver display program.

[0042] In the actual design of the display screen 1, the segment number 8-shaped digital tube 62, the segment time 8-shaped digital tube 61 and the countdown 8-shaped digital tube 63 are of different sizes and can be composed of light strips 12 of different lengths.

[0043] In this embodiment, the remote control 3 includes a processor 31, a keyboard module 32 and a wireless sending module 33, the keyboard module 32 and the wireless sending module 33 are both electrically connected to the processor 31, and the controller 2 is electrically connected to a wireless receiving module 21 for receiving signals sent by the wireless sending module 33.

[0044] The processor 31 is used to process the information of different keys pressed on the keyboard module 32, and send it to the wireless receiving module 21 through the wireless sending module 33, and finally send the corresponding information to the data transmission line 5 through the controller 2 to control the display of the light strip 12. The wireless remote control is simple and easy to implement.

[0045] The chips of the wireless transmission module 33 and the wireless receiving module 21 are NRF2401L single-chip radio frequency transceiver chips, and the keyboard module 32 is a commonly used BCD keyboard. The keyboard module 32 includes a pause key, a match score adjustment key (plus, minus), a quarter adjustment key, a countdown start key, a voice broadcast key, a match end key, a power on key, and a power off key.

[0046] In actual use, the keyboard module 32 can also be changed into a voice recognition module.

[0047] Because the entire basketball game timer is divided into two parts, a power supply needs to be set up separately to power each part.

[0048] The basketball game timer involved in this embodiment has a simple circuit design, is lightweight (light weight and easy to carry), is relatively cheap, is easy to operate (wireless), has a simple program design, and is easy to install and maintain.

[0049] Working principle: The keyboard module 32 and the processor 31 are connected to the I 2 C port connection, press a game score adjustment key (plus or minus) on the keyboard module 32, the processor 31 processes it and encodes it accordingly, and then sends it out through the wireless sending module 33; after the wireless receiving module 21 receives the signal sent by the wireless sending module 33, it transmits the signal to the controller 2 for processing. After the processing is completed, the controller 2 drives the corresponding light strip 12 to display through a data transmission line 5, and the display screen 1 displays the time changes of the corresponding game.

[0050] When a sound needs to be made, a voice broadcast key is pressed on the keyboard module 32, and the corresponding instruction is sent to the wireless receiving module 21 through the wireless sending device 33. After the wireless receiving module 21 receives the signal sent by the wireless sending module 33, the signal is transmitted to the controller 2 for processing. The controller 2 is connected to the voice broadcast module 4 through serial port communication, and the voice broadcast module 4 plays the currently displayed score content once.

[0051] Embodiment 2 See also Figures 1 to 5 As shown, this embodiment relates to a method for controlling a basketball game timer, comprising the following steps: S1, construct digital font arrays corresponding to different display areas of display screen 1, and form library functions corresponding to the fonts; controller 2 initializes the internal timer and starts it.

[0052] S2. Determine whether a signal is received within a preset time; If the first preset signal is received within the preset time, or no signal is received within the preset time, it is a timing mode and enters step S3; if the second preset signal is received within the preset time, it is a score module and enters step S10.

[0053] In this step, the entire basketball game timer is started, and the two different display modes are entered by inputting two different signals. Specifically, for example, if 1 is input within one minute, or there is no input within one minute, the timing mode is entered; if 2 is input within one minute, the score mode is entered. The two different display modes are used to improve the utilization rate of the display screen 1.

[0054] Of course, during the game, if you enter the timing mode, you can force the remote control 3 to switch to the score mode; similarly, if you enter the score mode, you can also force the remote control 3 to switch to the timing mode.

[0055] After this step is finished, the controller 2 controls the internal timer to close.

[0056] S3, initialize the internal timer and start it, initialize all 8-shaped digital tubes 6 connected to the data transmission line 5, define the remaining time of each section as i and assign an initial value, define the number of sections as j and assign an initial value, define the 24-second countdown as k and assign an initial value.

[0057] In this step, the remaining time i of each section is usually assigned a value of ten minutes, which is displayed as the number 1000. In order to distinguish between minutes and seconds, a ":" is usually added in the middle, so the final display is 10:00. The number of sections j is usually assigned a value of 4, which is displayed as the number 4. The 24-second countdown is usually assigned a value of 24, which is displayed as the number 24. After the 24-second countdown is started, the display will decrease by 1 after 1 second until it reaches 0.

[0058] S4, the controller 2 calls the library function corresponding to the font, and makes the 8-character digital tube 61 of each section time display the remaining time i of each section through the data transmission line 5, and makes the 8-character digital tube 62 of the section number display the section number j at the same time, and when the timer reaches one second, the remaining time i of each section is automatically reduced by one.

[0059] In the actual display process, for the current section number, the section number 8-shaped digital tube 62 displays the section number j unchanged; the section time 8-shaped digital tube 61 displays the remaining time i of each section, and i is displayed as the timer decreases by one every second.

[0060] S5, determining whether a signal to start a 24-second countdown is received; If so, the controller 2 calls the library function corresponding to the font, and makes the 8-character digital tube 61 for each section time display the remaining time i of each section, makes the 8-character digital tube 62 for the section number display the section number j, and makes the 8-character digital tube 63 for the countdown display the 24-second countdown k through the data transmission line 5, and enters step S6; otherwise, the controller 2 calls the library function corresponding to the font, and makes the 8-character digital tube 61 for each section time display the remaining time i of each section, makes the 8-character digital tube 62 for the section number display the section number j, and makes the 8-character digital tube 63 for the countdown display 00 through the data transmission line 5, and enters step S6.

[0061] According to the actual situation of the basketball game, the referee on the sidelines can send a signal to start the 24-second countdown through the remote control 3, and the wireless receiving module 21 sends the received signal to the controller 2 for processing.

[0062] S6, determining whether a pause signal is received; If so, the controller 2 calls the library function corresponding to the font, and through the data transmission line 5, the numbers displayed on the 8-shaped digital tube 61 for each section time, the 8-shaped digital tube 62 for the section number, and the 8-shaped digital tube 63 for the countdown remain unchanged, and enters step S7; otherwise, enters step S8.

[0063] In actual situations, the referee on the sidelines can send a pause signal through the remote controller 3, and after receiving the signal, the wireless receiving module 21 sends it to the controller 2 for processing.

[0064] S7, judging whether the pause signal is cancelled; If so, the controller 2 calls the library function corresponding to the font, and through the data transmission line 5, the numbers displayed on the 8-shaped digital tube 61 for each section time and the 8-shaped digital tube 62 for the section number remain unchanged, and the number k displayed on the countdown 8-shaped digital tube 63 is automatically reduced by one when the timer reaches 1 second. When k is reduced to zero, step S8 is entered; otherwise, return to step S7.

[0065] In actual situations, the referee on the sidelines can send a cancel pause signal through the remote controller 3, and after receiving the signal, the wireless receiving module 21 sends it to the controller 2 for processing.

[0066] S8, judging whether the remaining time i of each section is zero; If so, the section number j=j-1, the remaining time of each section is given an initial value i, the controller 2 calls the library function corresponding to the font, and makes the 8-font digital tube 61 of each section time display the remaining time i of each section through the data transmission line 5, and makes the 8-font digital tube 62 of the section number display the section number j at the same time, and enters step S9; otherwise, returns to step S4.

[0067] After each quarter of the game, the quarter number displayed on the quarter number 8-shaped digital tube 62 is reduced by one, and the remaining time i of each quarter is reset to ten minutes, that is, 10:00 is displayed.

[0068] S9, judging whether the number of nodes j is zero; If yes, the game is over. Otherwise, the process returns to step S4.
