Description: 三相交流电在国民经济中应用广泛，电路的畅通对工业生产极为重要。由于某种原因造成某相交流电断电，会造成重大的经济损失，因而对线路的检测是十分必要的。单片机三相交流电断相远程报警器，以8051单片机为核心，对三相线路进行不间断检测。当某相线路断电时，不仅可进行近程声光报警，还可进行远程声报警。-Three-phase alternating current widely used in the national economy, the circuit flow of traffic on the industrial production of paramount importance. For some causes of a phase AC power, will cause major economic losses, and thus the line detection is very necessary. SCM-phase long-range three-phase alternating current alarm to 8051 as the core, non-stop for three-phase circuit testing. When a phase power line, not only can be short-range sound and light alarm, sound alarm can also be remote. Platform: |

Description: 一、设计要求：交通信号灯模拟控制系统设计利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，并且用LED数码管显示时间。用8051做输出口，控制十二个发光二极管燃灭，模拟交通灯管理。
二、设计内容：因为本课程设计是交通灯的控制设计，所以要了解实际交通灯的变化情况和规律。假设一个十字路口为东西南北走向。初始状态0为东西红灯，南北红灯。然后转状态1东西红灯，南北绿灯通车，。过一段时间转状态2南北绿灯灭，黄灯亮5秒，东西仍然红灯。再转状态3，东西绿灯通车，南北红灯。过一段时间转状态4，东西绿灯灭，黄灯亮5秒，南北仍然红灯。最后循环至状态1。
注意：.双色LED是由一个红色LED管芯和一个绿色LED管芯封装在一起，公用负端。当红色正端加高电平，绿色正端加低电平时，红灯亮；红色正端加低电平，绿色正端加高电平时，绿灯亮；两端都加高电平时，黄灯亮。-First, the design requirements: traffic light control system using single chip analog timer timing, so that the traffic light intersection
Alternating light and off, and LED digital display with time. To do with the 8051 output, control, burning off a dozen light-emitting diodes,
Simulated traffic light management.
Second, the design of content: This course is designed for the control of traffic light design, so to understand the actual changes in traffic lights and rules
Law. Assuming a crossroads for the north-south thing. What the initial state 0 is red, north and south light. Then things turn state 1
Red, green north-south traffic. Over time, turn off State 2 South Green, yellow light for 5 seconds, things are still red. Sub-state
State 3, the opening of something green, north and south light. Switch to state 4 over time, things off the green, yellow light for 5 seconds, north and south are still red
Lights. The last cycle to the state 1.
