一、概述为了保证行车安全,使乘务员及时准确的了解运行前方的线路信号,在SS_1型电力机车上装有机车自动信号系统(见图1)。通过安装在机车排障器后的感应器383～386,从轨道接收信号,经控制电源联锁开关221(222)的联锁,把机车运行方向接收到的信号输入滤波器399,经共用箱使机车司机室内的双面显示信号机显示出相应的行车信号,从而乘务员能够及时的了解运行前方的信号,对行车安全起着极为重要的作用。 First, an overview In order to ensure traffic safety, flight attendant timely and accurate understanding of the line signal in front of running, the SS_1 locomotive equipped with locomotive automatic signaling system (see Figure 1). Receiving the signals from the rails via sensors 383-386 mounted behind the locomotive bug, the signal received in the locomotive running direction is input to the filter 399 via the interlock of the control power interlock switch 221 (222) So that the locomotive driver indoor double-sided display signal shows the corresponding driving signal, so the crew can understand the signal in front of the operation, on the driving safety plays an extremely important role.
