在径赛体育比赛中,为了提高运动员成绩的精确性和公平性,而传统的手工计很难实现这一需求,而以数字信号为基础的径赛起点信号处理系统的开发和应用,有效的解决了以上径赛体育比赛中所存在的问题。本文首先从径赛起点信号处理系统的主控系统的实现谈起,然后分别对发令子系统、起跑子系统以及无线通信子系统三个重要子系统的实现进行说明。 In the track and field competition, in order to improve the accuracy and fairness of the athlete’s performance, it is difficult for the traditional manual to realize this demand. However, the development and application of the digital signal-based track start signal processing system can effectively solve the problem The problems in the above athletic competitions. In this paper, we talk about the implementation of the main control system of the signal processing system at the beginning of the track, and then describe the implementation of the three important subsystems of the starting system, the starting system and the wireless communication system respectively.
