| 摘 要： | 为提高重载组合列车各重联机车无线控制的同步性能,基于800 MHz无线电空间波无线传输模式,建立重载组合列车分布动力机车重联控制无线传输同步性的马尔可夫决策模型,并采用有限阶段向后递归迭代算法进行求解.利用给出的决策模型和算法构建重载组合列车分布动力机车重联无线同步控制系统,并安装于神华线万吨重载组合列车的机车上进行测试.测试结果表明:机车间重联信息无线传输的平均周期仅为2.5s,小于美国GE公司LOCOTROL系统3s的平均周期,能够满足神华线重载组合列车运行的基本要求；采用800 MHz双频点组成双网传输,在无线电波弱场区能克服空间波传输受到干扰的影响,减少延迟时间. |
