Problems solved by technology

Nowadays, the judgment of the ball out of bounds is mostly judged by the naked eye of the line operator. Due to the fast movement of the ball and the low recognition accuracy of the human eye, the line operator often makes wrong judgments.
[0003] There are also some large-scale competitions that use the slow-motion playback system to assist in judging the out-of-bounds situation, but this technology affects the rhy

Embodiment 2

[0043] The out-of-bounds judging device 3 of Embodiment 2 also includes a timing compilation unit, and the timing compilation unit is such as Figure 5 , including K registers, K=m×n, the input pin of each register is correspondingly connected to an output pin of the output chip U2, the output terminal group of the timing compilation unit is connected to the input terminal group of the decoding analysis module, so The output terminal group of the decoding analysis module is connected to the input terminal group of the result prompting device 4 .

[0044] by Image 6 For illustration, the top state 1 represents the timing signal at time t1, at which time the current of all side trigger coils has not changed, and state 2 represents the timing signal at the next time t2, at this time, the current of one side trigger coil has changed, and the state 3 indicates the timing signal at the next time t3, in which the coil where the current changes is the adjacent coil of the changed co...

Abstract

The invention discloses a boundary ball judgment system based on electromagnetic disturbance. The boundary ball judgment system comprises a ball body (1), a boundary line (2), an out-of-bound judgment device (3) and a result prompt device (4); the out-of-bound judgment device (3) comprises m*n boundary trigger coils (31) and a trigger signal processing module (32), the m*n boundary trigger coils (31) are evenly buried in the boundary line (2) and areas in the inner side and the outer side of the boundary line (2), the end faces of the boundary trigger coils (31) and the plane of a court are mutually parallel, and a magnet/guide magnet (11) is fixed to the ball center of the ball body (1); and a signal receiving end set of the trigger signal processing module (32) is correspondingly connected with signal output end sets of the boundary trigger coils (31), and a result output end set of the trigger signal processing module (32) is connected into an input end set of the result prompt device (4). The boundary ball judgment system has the beneficial effects that the accuracy is extremely high, misjudgment caused by influences of player running is avoided, and all functions can further be achieved only through hardware.

Description

technical field [0001] The invention relates to the technical field of sideline ball detection, in particular to a boundary ball judging system based on electromagnetic disturbance. Background technique [0002] In ball games, whether the ball is out of bounds is crucial to the game. Once the judgment is wrong, it will have a negative impact on the game. Today, the judgment of the ball going out of bounds is mostly judged by the naked eyes of the line operator. Due to the fast movement of the ball and the low recognition accuracy of the human eye, the line operator often makes wrong judgments. [0003] There are also some large-scale competitions that use the slow-motion playback system to assist in judging the out-of-bounds situation. However, this technology affects the rhythm of the game, and it needs to be turned on continuously, and the operation loss is large, so it is not universal. [0004] Some boundary recognition units use pressure sensing. When the ball hits the...
