蒸汽机车需要有一个司机和一个司炉操作,而在内燃机车和电力机车上,原则上可以允许一人操纵。但易产生这样一种后果,即一旦机车司机突然失去操纵能力,司机室内没有第二个人能使列车停车。因此机车就需要有一种能监控司机操纵能力的装置。对这种司机监控装置,提出了以下二项基 Steam locomotives require a driver and a steamboat operation, while on diesel and electric locomotives, one can in principle be allowed to maneuver. However, a consequence of this is that there is no second person in the driver’s cabin to stop the train once the locomotive driver suddenly loses control. Therefore, locomotives need a device that can monitor the driver’s handling ability. For this driver monitoring device, the following two bases are proposed
