Intelligent electronic scoreboard based on voice recognition

Abstract

The invention discloses an intelligent electronic scoreboard based on voice recognition, which comprises a microphone, a controller, a driving circuit, an LED display circuit, an interface circuit and a power circuit. A judge announces current score in front of the microphone according to field competition conditions, the microphone transmits a judge signal to the controller to be recognized, voice contents of the judge are recognized, the score is displayed via the LED display circuit, the driving circuit is used for driving the LED display circuit, and a protecting circuit is used for realizing over-current protection of the LED display circuit. The voice recognition technology and the LED display technology are adopted, real-time scoring, display and storage of table tennis games, badminton games and the like are realized, according to competition rules, a program of a system automatically judges the time when courts need to be exchanged, and left and right scores are automatically exchanged when courts of the athletes are exchanged; and according to the competition rules, after a round of a game is finished, functions of automatically accumulating the score of the round, realizing history inquiry and the like are realized.

Description

technical field [0001] The invention relates to an intelligent electronic scoreboard based on speech recognition, which belongs to the field of electronic technology. Background technique [0002] At present, traditional mechanical scoreboards are mainly used in table tennis and badminton games. Because they have to be opened page by page, there are problems such as inflexible operation and easy misuse. In addition, because the brightness of the mechanical scoreboard cannot be adjusted, when the audience seats The distance makes it difficult to see the real-time score clearly. This design adopts voice recognition technology, and the referee sends the voice signal to the processing system through the wireless microphone, which avoids the misoperation caused by manually turning the score sheet, and at the same time, the score between rounds can be displayed in real time without manual operation. In addition, using LED display technology, the display brightness can be adjusted...
