摘要
对机车司机工作过程中的身体状态、疲劳程度提出了测试方法与评价模式。在作业前、作业２ｈ、作业３ｈ 、作业４ｈ 后４ 种状态下对其失衡性进行实时监测。受试者５０ 人，在座姿操纵整个过程中，当出现过度疲劳时，监测系统可及时提示。结果表明：失衡性在连续作业３ｈ 后与作业前相比差异显著（ｐ ＜ ０ ．０５） 。
The postural stability and fatigue degree of locomotive drivers are measured and evaluated. Fifty locomotive drivers are subject to the measurement with stabilometer and computer system in case of pre work, and work after 2 h, 3 h and 4 h respectively. Once the locomotive drivers in sitting posture are overfatigued with work, they can be timely warned by the monitoring system. Experimental results show that the locomotive drivers' postural unbalance are quite different between the two conditions: pre work and work after 3 h (p<0.05).
