A badminton speed measurement system and method combining laser array and intelligent terminal

Abstract

The invention provides a laser-array and intelligent-terminal combined shuttlecock speed measuring system and method. The laser-array and intelligent-terminal combined shuttlecock speed measuring system comprises a shuttlecock speed collecting subsystem and a shuttlecock speed display and management subsystem. The shuttlecock speed collecting subsystem comprises a transmitting device and a receiving device. The transmitting device and the receiving device are located at the two ends of the upper portion of a badminton net respectively. The transmitting device comprises a laser transmitter array, a wireless module, a controller and a power supply module. The receiving device comprises a laser sensor array, a wireless module, a controller, a power supply module, a Bluetooth module and a display module. The laser transmitter array comprises two rows of laser heads arranged at an equal interval and can transmit two sets of parallel laser beams. Each set of laser beams are composed of multiple laser beams distributed in the same plane at an equal interval. The planes where the two sets of parallel laser beams are located are both parallel to the badminton net. The laser sensor array comprises two rows of laser sensors distributed at an equal interval and is used for receiving the two sets of parallel laser beams transmitted by the laser transmitter array. Alternating current power supply and / or battery power supply can be adopted for the power supply modules. The two subsystems can be in wireless data communication. The shuttlecock speed display and management subsystem comprises intelligent terminals. The functions of speed displaying, history records, the maximum record, score sharing and the like can be achieved.

Description

technical field [0001] The present invention generally relates to the technical field of laser velocimetry. In particular, it relates to a badminton speed measurement system combined with a laser array and an intelligent terminal, and a badminton speed measurement method, belonging to the field of sports training equipment. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to physical exercise outside the busy work. And badminton, because of its extensive mass base and sports development level in our country, is loved by the majority of sports enthusiasts. In a badminton game, if the serving technique is high, the direct scoring rate will be high, and the quality of the opponent's return will be low, so as to facilitate one's own attack. [0003] The existing badminton table only provides a platform for practice when the players are training, and the serving speed of the players cannot be obtained, so it is ...
