正常控制时：如图1所示,它是按信号灯置1与置0两种状态绘制的,置1表示信号灯点亮.SA1手柄指向左45º时,接点SA1-1接通,东西向红灯亮30s,南北向绿灯亮,25s后南北向绿灯闪烁3s,然后熄灭.在绿灯熄灭的同时,东西向黄灯亮2s,然后熄灭.在该灯熄灭的同时,南北向红灯亮及东西向绿灯亮,以下的变化规律与上述相同.到南北向绿灯亮,东西向红灯亮开始第二个循环,以后周而复始地循环动作.同时南北向及东西向均有两位数码管倒计时显示相应指示灯的剩余时间值
非正常控制时：SA1手柄指向中间0º时,接点SA1-2接通,交通指挥系统南北向绿灯常亮,东西向红灯常亮,数码管显示99不变.
SA1手柄指向右45º时,接点SA1-3接通,交通指挥系统东西向绿灯常亮,南北向红灯常亮,数码管显示99不变
非正常控制时：SA1手柄指向中间0º时,接点SA1-2接通,交通指挥系统南北向绿灯常亮,东西向红灯常亮,数码管显示99不变.
SA1手柄指向右45º时,接点SA1-3接通,交通指挥系统东西向绿灯常亮,南北向红灯常亮,数码管显示99不变

Normal control: as shown in figure 1, it is according to the light 1 and 0 draw two kinds of state, said 1 lamp light.SA1 handle refers to the left 45 DHS, contact on SA1-1, east-west turns red, 30 s, north and south to green light, north and south to green light flashing 3 s after 25 s, and then go out.In the green light to go out at the same time, the east-west yellow lights 2 s, and then go out.In the lights at the same time, the east-west turns red, and the south-north green light, the change rule of the same.East-west to north and south to green light, red light began to the second loop, periodic cycle action in the future.At the same time are two north-south and east-west countdown digital pipe display time remaining value of the corresponding indicator light abnormal control: when the SA1 handle pointing middle 0 DHS, contact SA1-2 connected, north and south to green light Chang Liang traffic command system, run the red light Chang Liang, digital tube display 99 remains the same.
SA1 handle 45 DHS, pointing to the right contact SA1 3 connected, traffic command system Chang Liang east-west, north and south to red light Chang Liang, digital tube display 99 remains the same.
When abnormal control: SA1 handle pointing middle 0 DHS, contact SA1-2 connected, north and south to green light Chang Liang traffic command system, run the red light Chang Liang, digital tube display 99 remains the same.
