Description: 本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。
-The system uses MSC-51 Series Microcontroller ATSC51 and programmable parallel I/O interface chip 8255A-centric devices to design traffic signal controller based on the actual traffic flow can be achieved through the P1 port 8051 chip set of red, green, gave the time of function traffic light cycle of light, the countdown 5 seconds left when the yellow light flashing warning (traffic light signal through the PA port output, display time directly through the 8255 output of the PC port to double-digit nixie tube) of vehicles running red lights warning green time can detect vehicles flow can be through a double-digit LED display. The system practical, simple, extending strong function. Platform: |

Description: 交通灯控制器主要是利用了一个计数器芯片的计数，当计数器开始有稳定的秒脉冲输入时就开始计数，秒脉冲是用555多谐振荡器产生的，然后再通过各种门电路的逻辑组合实现最后的交通灯功能。-Traffic light controller is to use a counter chip count when the counter started a steady start when seconds count input pulse, second pulse is over 555 harmonic oscillator, and then again through the logic gate combination functions to achieve the final traffic light.

Description: 交通灯控制器设计：1．有MR(主红)、MY（主黄）、MG（主绿）、CR（乡红）、CY（乡黄）、CG（乡绿）六盏交通灯需要控制；
2．交通灯由绿→红有4秒黄灯亮的间隔时间，由红→绿没有间隔时间；
3．系统有MRCY、MRCG、MYCR、MGCR四个状态；
4．相间公路右侧各埋有一个传感器，当有车辆通过相间公路时，发出请求信号S；
5．平时系统停留在MGCR状态，一旦S信号有效，经MRCY转入MRCG状态，但要保证MRCG状态也不得短于一分钟；
6．一旦S信号无效，系统脱离MRCG状态。随即经MRCY转入进入MGCR状态，计时S信号一直有效，MRCG状态也不得长于20秒钟。
-Traffic light controller design: 1. With MR (the main red), MY (Master Wong), MG (Master Green), CR (township red), CY (Rural yellow), CG (village green) six traffic lights need to control
2. → red traffic light from green to bright yellow with 4 seconds intervals, not from red → green interval
3. System MRCY, MRCG, MYCR, MGCR four states
4. The right side of the road white buried a sensor, when a vehicle through the white road, the request signal S
5. MGCR usually stay in the state system, once the S signal is valid, the MRCY into MRCG state, but also to ensure that the state shall not be less MRCG one minute
6. Once the S signal is invalid, the system from MRCG state. Then transferred into MGCR by MRCY state S signal timing has been effective, MRCG status is no longer than 20 seconds. Platform: |

Description: 交通灯控制器在A、B方向各有红、黄、绿三盏灯，其控制顺序按表的设计进行循环，表中1表示灯亮、0表示灯灭。交通灯控制器按照主干道数码管显示50S，支干道数码管显示30S, 主干道变为红灯，支干道变为绿灯，继续进行倒计时；支干道倒计时结束后再经行5秒倒计时，交通灯变为黄灯；支干道倒计时结束后再回到初始状态。-Traffic light controller in A, B direction of each red, yellow, and green light, the control sequence of the design cycle according to the table, the table 1 that light, 0 is lights out. Main road traffic light controller in accordance with digital display 50S, branch roads digital display 30S, the main road into the red, branch roads into the green light to continue the countdown branch roads countdown after the end of the line five seconds after the countdown, traffic lights becomes yellow branch roads after the end of the countdown to the initial state.
