近年来，随着科技的飞速发展，单片机逐渐得到人们的青睐。使用单片机需要结合具体的软硬件结构。十字路口车辆穿梭能够有条不紊，交通信号灯的自动指挥系统在此扮演了一个重要的角色。城市道路车流量大，经常出现"堵车"现象，改善红绿灯处交通灯控制系统十分必要。针对交叉路口拥堵、道路交通拥堵的情况，提出了基于单片机的智能交通灯控制系统设计。交通灯控制系统设计包括按键控制、时间显示、指示灯。按键完成对系统时间的设置，可以调整路口红绿灯变换的时间数据，可以切换进入到紧急状态模式。4组2位一体式数码管显示各自路口的时间数据。4组红绿灯指示路口通行状态。8组人行道红绿灯指示通行状态。系统最终完成了按键控制、时间显示、指示灯控制方案、硬件、软件设计，依据理论设计完成实物制作。并对系统功能进行逐一的测试，测试结果显示完全达到最初设计的功能要求。

In recent years, with the rapid development of science and technology, single chip microcomputer has gradually been favored by people. The use of single chip microcomputer needs to be combined with specific software and hardware structure. Vehicles can shuttle in an orderly way at intersections, and the automatic command system of traffic lights plays an important role here. The traffic flow of urban roads is large, and the phenomenon of "traffic jam" often occurs. It is very necessary to improve the traffic light control system at the traffic lights. Aiming at the situation of intersection congestion and road traffic congestion, the design of intelligent traffic light control system based on single chip microcomputer is proposed. The design of traffic light control system includes key control, time display and indicator light. Press the key to complete the setting of the system time, adjust the time data of traffic light transformation at the intersection, and switch to the emergency mode. Four groups of 2-bit integrated nixie tubes display the time data of each intersection. Four groups of traffic lights indicate the traffic status of the intersection. 8 groups of sidewalk traffic lights indicate the traffic status. Finally, the system completes the key control, time display, indicator control scheme, hardware and software design, and completes the physical production according to the theoretical design. The system functions are tested one by one, and the test results show that it fully meets the functional requirements of the original design.

In recent years, with the rapid development of science and technology, single-chip microcomputer has been gradually favored by people. It is necessary to combine the specific hardware and software structure to use single chip microcomputer. Traffic shuttle at intersections can be orderly, and the automatic command system of traffic lights plays an important role here. Traffic jams often occur in cities because of the heavy traffic volume, so it is necessary to improve the traffic light control system at traffic lights. Aiming at the situation of intersection congestion and road traffic congestion, this paper puts forward the design of intelligent traffic light control system based on single chip microcomputer. The design of traffic light control system includes key control, time display and indicator light. Press the key to set the system time, adjust the time data of traffic lights at intersections, and switch to emergency mode. Four groups of 2-in-one digital tubes display the time data of their respective intersections. Four sets of traffic lights indicate the traffic conditions at intersections. Eight groups of sidewalk traffic lights indicate traffic conditions. Finally, the system completed the key control, time display, indicator light control scheme, hardware and software design, and finished the physical production according to the theoretical design. The functions of the system are tested one by one, and the test results show that it completely meets the original design requirements.
