在机车远距离控制装置中,出现除机车重大事故之外的故障时,设置了能使机车自动减速而又能保护机车的自动减速装置。本装置电路结构简单,而且便于调整。 图为使用CM3的自动减速装置的一个实例。通常用比较器比较速度给定器SPC的给定信号F和来自驱动器ACT的反馈信号B,将偏差信号L作为驱动器ACT的输入,并控制机车ENG的速度。自动减速装置由比较器CM3与大地之间所接的二极管M、N、P、Q,以及路闸R构成。当出现需要自动减速情况时,路闸R闭
In the locomotive remote control device, in addition to a major accident occurred outside the locomotive fault, set to enable the locomotive automatic deceleration but also to protect the locomotive automatic deceleration device. The device circuit structure is simple, and easy to adjust. An example of an automatic decelerator using the CM3. A given signal F of the speed setter SPC and a feedback signal B from the drive ACT are usually compared with comparators and the deviation signal L is input to the actuator ACT and the speed of the locomotive ENG is controlled. The automatic decelerating device is composed of diodes M, N, P, and Q connected between the comparator CM3 and ground, and a gate R. When there is a need to automatically decelerate the situation, the road gate R closed
