Problems solved by technology

There are two disadvantages in this method: First, in order to ensure the fairness of the ruling, a game has to use a large number of referees, resulting in a waste of personnel
The second is that because the race walking competition schedule is generally far away, the movements of the athletes are not large but very fast. It is impossible to observe every step of each athlete in place through visual inspection.
Therefore, it is inevitable that referees miss judgments, misjudgments, and disputes between referees and athletes, so that race walking fouls become the most difficult to judge in all competitive sports events, and one of the most controversial projects for referees. Sports workers are pressing for a fix

Embodiment 1

[0018] Embodiment 1: as figure 1 As shown, the whole system consists of three parts: athlete device, data concentrator and referee PC; the athlete device is responsible for collecting the movement data of athletes and making foul judgments, and transmitting the foul information of athletes to the data aggregator through wireless; the data converging The device is connected to the referee's PC through the USB interface, and uploads the received athlete's foul information to the referee's PC in real time; the referee's PC is responsible for storing and displaying information such as whether the athlete has fouled, the type of foul, and the number of fouls.

[0019] Such as figure 2 As shown, the wireless detector consists of four parts: sensor (pressure sensor or strain sensor), processor, UWB chip and button battery. The sensor is responsible for collecting the movement information of the athletes; the processor selects an embedded chip with analog-to-digital conversion funct...

Abstract

The invention discloses an intelligent heel-and-toe walking race foul monitoring system based on a UWB (ultra-wide bandwidth) mobile sensor network, which can effectively resolve problems that erroneous judgment, miss judgment and the like are frequently caused in a head-and-toe walking race competition due to human judgment. The intelligent heel-and-toe walking race foul monitoring system comprises an athlete device, a data collector and a judge PC (personal computer). The athlete device is in charge of acquiring data and foul judgment; the data collector is in charge of collecting foul information and uploads the foul information to the judge PC; and the judge PC is in charge of storing and displaying the foul information. A pressure sensor and a strain sensor are used as athlete action detecting devices, a networking mode of a mobile automatic-organization network (MANET) is adopted for the system, UWB technology is used for wireless communication, and 'rising foul' and 'knee bending foul' actions of an athlete can be detected in real time and are wirelessly transmitted to the judge PC. The intelligent heel-and-toe walking race foul monitoring system is advanced in technology, complete in function and high in intelligence degree, and is a powerful tool for assisting in daily training of athletes and eliminating judgment disputes of heel-and-toe walking race competitions.

Description

technical field [0001] The invention relates to a monitoring system in competitive sports events, in particular to a monitoring system for walking fouls. Background technique [0002] Race walking competition is a track and field sport with very high requirements for movement specifications. There are two core rules for lower body sports: First, a race walking athlete must always keep at least one foot on the ground, that is, there must be no "flying" action ;Secondly, from the moment the forward foot hits the ground until the leg reaches a vertical position, the leg must remain straight and the knee cannot be bent. Violation of these two rules is considered a foul. The former is called a "flying foul" and the latter is called a "knee foul". At present, the foul judgment in domestic and international race walking competitions still adopts the method of visual inspection, supplemented by video recording. There are two disadvantages in this method: First, in order to ensure ...
