说明：  当前，运动会已经在全国普遍开展，许多学校每年都定期的举行不同规模的田径运动会。但是，在运动会举行过程中一直存在着参赛人数多，项目设置复杂，时间安排紧凑等问题，而且这些问题能否解决直接关系着运动会的成功与否。另一方面，人们对于比赛结果的实时性、准确性、安全性、可靠性的要求也越来越高，而这些要求是人工操作很难实现的。
(At present, the sports meet has been carried out widely in the country. Many schools hold regular track and field sports on different scales every year. However, in the process of the games, there are many problems, such as the large number of participants, the complex project settings and the tight schedule, and whether these problems can be solved directly related to the success of the games. On the other hand, people have higher and higher requirements for real-time, accuracy, security and reliability of the game results, which are difficult to achieve by manual operation.)
