Problems solved by technology
However, in the current long jump and triple jump, plasticine is placed on the front side of the springboard. The purpose is that when the athlete crosses the boundary, there will be marks on the plasticine. However, when the athlete crosses the boundary, there is no trace or the trace is slight, which cannot be judged.
Due to the lack of objective and accurate judgment tools for referees, in many competitive sports, judgments are only based on vision and experience, so there are often problems such as wrong judgments and missed judgments, which affect the competitive and fair judgment of sports

Embodiment
[0014] Example: a structure such as figure 1 , 2 and image 3 As shown, it consists of an alarm 5 and a pressure-sensitive conductive rubber switch plate 4. The pressure-sensitive conductive rubber switch plate 4 is closely placed in front of the take-off board 1, that is, on the original plasticine position. The pressure-sensitive conductive rubber switch plate 4 is formed by the electrode 3. , conductive rubber RP and insulating film 2, the length is 1220MM, the width is 100MM, and the thickness is 7MM. The conductive rubber is sandwiched between two electrodes 3, and there is an insulating film 2 on the outside of the electrode, which is connected to the alarm through wires; The circuit is composed of battery E, indicator light D, buzzer FM, relay J and time relay Js, and the components are electrically connected. The pressure-sensitive conductive rubber switch plate 4 is a high-density switch device. When an athlete steps over the springboard and touches any part of the ...

The invention relates to an alarm for competition, in particular to a border cross alarm device for step to jump competition, which belongs to the sports train equipment technology field. It consists of an alarm device and pressure-inducting electricity-conducting switch panel. Wherein, the pressure-inducing electricity-conducting switch is set closely in front of the gangboard, connecting with the alarm device by the conducting wires. Said pressure-inducing electricity-conducting rubber switch panel is composed of electrodes, electricity conducting rubber and insulation film, wherein, the electricity conducting rubber being clamped by two electrodes, the electrodes having insulation film in outside. The alarm device circuit is formed by battery, indicating lamp, relay and time relay, which are connected by circuit. If the sport man crosses the border when steps for jumping, whatever the extent of the border crossing is, the device will send out sounds and light to indicate the sports man to foul.
Description
(1) Technical field [0001] The invention relates to an alarm for competition, which belongs to the technical field of sports training equipment. (2) Background technology [0002] With the rapid development of world sports and the continuous improvement of competitive levels, new and higher requirements have been put forward for referees of competitive sports. However, in the current long jump and triple jump, plasticine is placed on the front side of the springboard. The purpose is that when the athlete crosses the boundary, there will be marks on the plasticine. However, when the athlete crosses the boundary, there is no trace or the trace is slight, which cannot be judged. . Due to the lack of objective and accurate judgment tools for referees, in many competitive sports, judgments are made only by vision and experience, so problems such as wrong judgments and missed judgments often occur, which affect the fairness of sports competitions. Therefore, improving the scient...
