[Retracted] Design and Research of a Foul Detector for Long Jump Stepping on a Jump Line Based on the Wireless Sensor Network

In view of the problems of the judgment of the referee in international long jump competition, such as the omission and wrong judgment, a real-time, accurate, and effective detection instrument is designed. The sensor carried on the athlete is used as the detection element of the foul, which ensures the accuracy and timely information acquisition and effectively prevents the wrong judgment and the missed judgment. The system data is transmitted by the wireless sensor network, which is highly safe and reliable. The experimental results show that compared with the traditional artificial judgment results, the long jump crossover line foul detector based on the wireless sensor network can realize the accurate detection of the number of fouls. The judgment error is lower than the requirements of track and field rules for detection tools, which has great practical value and economic significance.
