摘要
竞走是我国田径备战世界大赛的重中之重的项目。平常训练、实际比赛中队员有犯规嫌疑就会被警告,没有什么可靠的依据。如果运动员满足竞走定义,有犯规嫌疑,就被裁判警告并罚下场,这样有时就会对有些运动员不公平。文中根据竞走的定义和核心规则,分析了竞走在比赛、训练中可能存在的问题,并结合实际情况,采用555时基电路设计了一种竞走违规检测电路,并介绍了安装方法。该设计主要针对双脚离地犯规进行检测,如果运动员双脚同时离地犯规红外线检测仪就能检测到,同时计数器计数一次,蜂鸣器也发出声音提示运动员犯规。
Race walking is preparing for the World Series of Track and Field priority projects. In practical training and game,players that have suspected foul will be warned,there is no reliable basis. If athletes meet the definition of race walking,there is suspicion of foul,and might have been cautioned or sent off,so that sometimes would be unfair to some athletes. According to the definition and central regular of race walking,the problems existed in the competition and training of race walking are analyzed and combined the actual situation,the foul detection circuit in race walking based on 555 timer is designed and the installation method is introduced. This design is mainly for the foul that both feet go off the ground,if the athletes＇ feet go off the ground at the same time,the infrared detector can detect this phenomenon,and a counter counts one time,buzzer also makes a sound that hints athletes have been foul.
