目的探讨客运机车司机疲劳状况。方法采用随机抽样方法分别抽取52名机车司机和65名地面勤杂工作人员进行疲劳调查,同时进行视觉疲劳检查。结果观察组主观疲劳感明显增强。观察组复杂选择反应时各项平均变化率明显升高,而闪烁融合频率各项平均变化率明显降低。结论机车司机值乘后的疲劳增强。建议为了减轻机车司机的工作负荷,应考虑由地面勤杂工作人员来完成部分机车准备工作。
Objective To investigate the fatigue status of passenger locomotive drivers. Methods A random sampling method was used to collect 52 locomotive drivers and 65 ground crew members for fatigue investigation and visual fatigue check. Results The subjective fatigue of the observation group was significantly increased. The average change rate of the complex group in the observation group was significantly increased, while the average change rate of the scintillation fusion frequency was significantly reduced. Conclusion The fatigue of the locomotive driver is increased. It is suggested that in order to reduce the workload of the locomotive driver, it is necessary to consider the ground work personnel to complete part of the locomotive preparation work.
