Description

Technical Field

[0001] This utility model relates to the field of scoring circuits, and in particular to a scoring circuit for pickleball. Background Technology

[0002] Pickleball is a net-based competitive sport in which players use a solid racket to hit a ball across a net. It originated in 1965 on Bainbridge Island in Seattle, USA. It combines elements of tennis, badminton, and table tennis.

[0003] Pickleball is a relatively new sport, and a mature scoring management system is still lacking. To facilitate scoring, manual methods are commonly used. As market demand grows, more convenient and flexible scoring methods will emerge, such as using wristbands. When using wristbands, athletes must wear them. The scoring player presses buttons on the smart wristband, and the management system automatically scores based on these button presses. However, wristband scoring has significant drawbacks: it's inconvenient to operate, prone to accidental touches leading to misjudgments, and the wristbands are easily damaged by impacts. Therefore, to address the issues of accidental touches and damage caused by wristbands in pickleball scoring, a centralized scoring system needs to be developed to centrally calculate pickleball scores and unify the scores for both players. However, there is a lack of existing reference design circuits for pickleball scoring, necessitating the development of a circuit capable of centralized pickleball scoring. Utility Model Content

[0023] This invention proposes a scoring circuit for pickleball.

[0024] In the embodiments of this utility model, such as Figure 1 As shown, the scoring circuit for pickleball includes: a main control module 101, a display screen 102, a matrix keypad 103, a speaker module 106, an NFC module 104, and a power supply module 105. The main control module 101 is connected to the display screen via an SPI bus. The display screen 102 is used to display the pickleball score. The main control module 101 is connected to the matrix keypad 103, which is used to trigger the pickleball score by pressing buttons. The main control module 101 is connected to the speaker module 106, the NFC module 104, and the power supply module 105. The NFC module 104 is used to read pickleball racket information.

[0025] Please see Figure 2a , Figure 2a This is a schematic diagram of the ESP32-S3R8 chip used in the scoring circuit of pickleball according to this utility model. Figure 2bThis diagram illustrates the external interface structure of the ESP32-S3R8 chip used in the scoring circuit of pickleball, as described in this invention. The ESP32-S3R8 chip is a QFN-56 single-chip solution from Espressif Systems, which integrates the ESP32-S3 dual-core processor and 8MB Octal-SPI PSRAM. The ESP32-S3R8 chip has built-in Bluetooth modulation functionality, supporting Bluetooth 5.0 (LE + Mesh), enabling Bluetooth communication without the need for an external Bluetooth chip.

[0026] The working principle of this utility model is as follows: the display screen 102 is used to display the results in human-computer interaction; the main control module 101 has a built-in Bluetooth module for wireless communication and data exchange with the built-in Bluetooth module of the Peak racket; the NFC module connected to the main control module 101 is used to quickly communicate with the built-in NFC module of the Peak racket to complete the quick pairing action; and the speaker module 106 is used to broadcast the operation results.

[0027] After the Bluetooth-enabled host is powered on, the display screen 102 is in standby mode. Players can input match information, define team names, etc., using handwriting input or a keyboard on the display screen. Simultaneously, the host's NFC module 104 is in synchronous standby mode. When Team A is selected, and a Peak racket A is brought close to the NFC module 104, the racket's ID information is quickly read, and the racket is automatically set as Team A. Similarly, when a new racket is brought close to the NFC module 104, the ID information of another Peak racket is quickly read, and the racket is automatically set as Team B. During the match, when Team A scores, pressing the hidden button on racket A transmits the button operation to the main control module 101 via Bluetooth. The main control module 101 recognizes the data, performs logical judgment, and converts it into score data, which is then displayed on the display screen 102. Similarly, when player B scores, pressing the hidden button under racket B will transmit the button operation to the main control module 101 via Bluetooth. The main control module 101 recognizes the data, performs logical judgment, and converts it into score data, which is then displayed on the screen 102. To end the match, players can operate the touchscreen display / or matrix button panel 103. Match information will be automatically saved and stored in the local database. Match data can also be shared to an instant messaging platform / or cloud platform. At the end of the match, the speaker module 106 will automatically announce the result. The system can also be set to multiplayer mode. The Bluetooth module of the main control module 101 allows more than four Peak rackets to be paired and used simultaneously.
