Stadium pressure alarm system

Abstract

The invention relates to the technical field of sports equipment, in particular to an alarm system. The stadium pressure line alarm system includes a sensor system, the sensor system is connected to the signal processing module, the signal processing module is connected to the alarm device, the sensor system includes a laser beam sensor system, and the laser beam sensor system includes a laser emitting device and a laser receiving device The power supply is connected through a switch, and the laser receiving device is connected to the signal processing module; the laser beam-to-shoot sensor system is used for the sensor system on the boundary line of the court. Due to the adoption of the above-mentioned technical solution, the present invention avoids misjudgments and missed judgments by referees due to balls or athletes pressing the line, and ensures the fairness, impartiality, continuity of sports competitions and normal performance of athletes' skills.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an alarm system. Background technique [0002] In the fierce competitions of tennis, volleyball, basketball, football and other sports, referees often misjudge or miss judgments due to the ball or players pressing the line, which causes controversy and even interrupts the game, greatly affecting sports. The fairness, impartiality, continuity of the competition and the normal performance of the athletes' skills also put forward higher requirements for the referees. At present, in ball games, the position of the ball touching the ground is mainly determined by the referee's visual judgment, and the extremely high ball speed makes it easy for the referee to misjudge or miss. For example, the speed of tennis balls is often as high as about 200 kilometers per hour, which makes it very fast to land, and even a fast camera is difficult to distinguish due to the difference in v...

At present, in ball games, the position of the ball touching the ground is mainly determined by the referee's visual judgment. The extremely high ball speed makes it easy for the referee to misunderstand or miss

For example, the speed of tennis balls is often as high as 200 kilometers per hour, which makes it very fast to land. Even if you take a fast camera, it is difficult to distinguish due to the difference in viewing angle due to different shooting angles.
