摘 要:竞走是田径项目中一项容易产生判罚争议的比赛,为了能够更好地帮助裁判判罚,解决判罚争议问题,设计了一款基于超声波测距模块HC-SR04的竞走训练检测装置。该装置采用了555定时器产生脉冲信号,利用红外传感器和超声波传感器,分别对双脚离地犯规技术动作以及双腿弯曲不规范的技术动作进行监测,当出现犯规动作时蜂鸣器就会发出警报。测试结果表明,相较于裁判的肉眼判罚,该装置对运动员犯规行为判罚的准确性更高,可以广泛应用于竞走训练和比赛中,帮助运动员训练和辅助裁判员执裁。Race walking is a competition prone to penalty dispute in track and field events. In order to better help the referee with penalty and solve penalty disputes,a race walking training and detection device based on HCSR04 is designed. The device uses a 555 timer to generate pulse signals,using infrared sensors and ultrasonic sensors to monitor the foul movements to both feet off the ground and the improper bending of legs. The buzzer will give an alarm when a foul is committed. The test results show that the device is more accurate than the referee’s eye in penalty and can be widely used in race walking training and competition to help the athletes with the training and the referees with the judging.
