Remote control prompting device for sports based on radio frequency technology

Abstract

The invention provides a remote control prompting device for sports based on a radio frequency technology. The device comprises a base and a radio frequency remote control, wherein the bottom face ofthe base is fixedly provided with a plurality of moving wheels, a transverse plate is arranged above the base, the bottom face of the transverse plate is fixedly connected with the top face of the base through a plurality of height adjusting rods, the radio frequency remote control is placed at the top face of the transverse plate, the middle of the top face of the transverse plate if fixedly provided with a motor with an independent power source, a triangular plate is arranged above the motor, the bottom face of the triangular plate is fixedly connected with the top face of the transverse plate through a plurality of supporting legs, the middle of the top face of the triangular plate is provided with a through hole, a vertical rotating rod penetrates through the through hole, and the lower end of the rotating rod is fixedly connected with an output shaft of the motor. The remote control prompting device for sports based on the radio frequency technology has the advantages that the structure is designed reasonably, the use is convenient, the height can be adjusted, moving is facilitated, convenience is brought for the use, and the number of referees and the labor intensity of the referees can be reduced; a display screen can be rotated, thereby providing convenience for a user to view the content on the display screen, dead ends are avoided, needs of the user are met, and the applicability is strong.

Description

technical field [0001] The invention belongs to the field of sports, in particular to a radio frequency technology-based sports remote control prompting device. Background technique [0002] In the sports field, usually the scene environment is relatively noisy, and the people participating in the sports may not be able to hear the whistle in time due to the influence of the environment. As a result, sports cannot be carried out normally. In some sports with hearing-impaired people, such as basketball games with hearing-impaired people, colorful flags are used as a signaling tool to replace the function of the referee's whistle. When there is a foul or violation in the game and the game needs to be suspended, the colored flag serves as a reminder for the suspension of the game. Due to the limitation of people's sight and angle of view, and the reason that people's attention is difficult to disperse in a tense game, it is usually impossible to suspend the game in time by wa...

AI Technical Summary

Problems solved by technology

Due to the limitations of people's sight and perspective, and the difficulty of distracting people's attention in a tense game, it is usually impossible to suspend the game in time by waving the flag

On the other hand, many referees are not used to judging directly with colorful flags, so they need to be equipped with assistant referees who are responsible for waving flags during the game

It can be seen that using flag-waving as a way to signal the termination of sports not only needs to increase the number of referees, but also is difficult to achieve a good prompting effect. For this reason, we propose a remote-controlled prompting device for sports
