A portable intelligent terminal for match referees

Abstract

The invention provides a portable intelligent terminal for a competition judge. The portable intelligent terminal comprises a shell, wherein a clamping mechanism used for clamping the terminal to thebody of the judge is arranged on the shell. The terminal further comprises a voice signal receiving module, a collecting module, a main control panel and a wireless signal receiving and sending module, wherein the voice signal receiving module is used for receiving voice signals of the competition scene and converting the voice signals into electric signals; the collecting module carries out filtering on the electric signals coming from the voice signal receiving module, and converts the filtered signals into square-wave signals; the main control panel receives the square-wave signals and processes the square-wave signals; the wireless signal receiving and sending module can send the processing result of the main control panel to the other devices except the terminal. The intelligent terminal is compact in structure and reasonable in design, can accurately and efficiently collect judgment commands sent by the judge during the competition, and can be used for the automatic and intelligent timing, scoring, and the like of the competition judge.

Description

technical field [0001] The invention relates to the technical field of signal acquisition and processing, in particular to a portable intelligent terminal for match referees. Background technique [0002] In the existing sports competitions, the referee's whistle, gestures, gunshots, etc. are usually used as referee signals for timing and scoring. Therefore, the collection and processing of referee signals is of great significance for improving the automation, intelligence and accuracy of referee timing and scoring. Although there are many collection technologies such as voice and action in the prior art. However, there are no reports on the specialized and customized related technologies used by referees in sports competitions. [0003] Especially in ball games, such as basketball, football, volleyball, etc., the referee usually needs to run back and forth on the field, and the referee's order is usually issued through whistle, but the sound environment is usually more co...

Problems solved by technology

However, there are no reports on the specialized and customized related technologies used by referees in sports competitions.

[0003] Especially in ball games, such as basketball, football, volleyball, etc., the referee usually needs to run back and forth on the field, and the referee's order is usually issued through whistle, but the sound environment is usually more complicated in the game scene, with cheers, whistles, etc. sound, footsteps, background music, ball vibration during ball games, etc., it is quite challenging to accurately collect the referee's whistle from such a complex sound environment. There is a lack of technical solutions that can effectively solve the above technical problems in the patent literature
