摘　　要：传统马拉松比赛电子计时器复位方法的自动控制性能较差,为提高马拉松比赛电子计时器的计时准确性,提出基于平衡态的马拉松比赛电子计时器自动复位方法。构建马拉松比赛电子计时器复位参数识别模型,结合掉电复位方法对复位参数进行调节,在复位参数调节的基础上,利用小波检测器对马拉松比赛电子计时器复位信号进行特征分解,实现马拉松比赛电子计时器复位的自适应控制,经复位信号特征分析后,提取复位信号特征,建立复位信号输出的动态相位补偿模型,并通过波束间隔均衡控制方法,结合平衡状态参数特征分析,实现马拉松比赛电子计时器自动复位。测试结果表明,采用该方法进行马拉松比赛电子计时器复位的自动控制能力较好。In order to improve the timing accuracy of Marathon electronic timer,an automatic reset method of Marathon electronic timer based on equilibrium state is proposed.Based on the adjustment of reset parameters,wavelet detector is used to decompose the reset signal of Marathon electronic timer to realize the adaptive control of Marathon electronic timer reset.After the characteristic analysis of reset signal,the reset signal is extracted.The dynamic phase compensation model of reset signal output is established,and the automatic reset of Marathon electronic timer is realized through the beam spacing equalization control method combined with the analysis of balance state parameter characteristics.The test results show that the automatic control ability of resetting electronic timer in marathon is better.
