摘　　要：针对目前交通信号灯红绿灯时间设置固定不变的情况,采用基于PLC技术设计的交通信号灯控制系统,在满足基本功能的前提下,提出并重点解决了“24 h分时段全自动智能切换红绿灯时间设置”的控制及“急通”功能的实现,同时给出了完整的硬件接线图和控制程序。通过自制的模拟电路对控制系统进行了调试与运行,该系统既能减轻交通高峰期的拥堵,又能减少非交通高峰期的时间等待,还能随时为紧急通行车辆开启绿灯,能有效提升交通系统运行效率和管理水平,达到了预期设计效果。In view of the current situation that the traffic signal time setting of the existing traffic signais fixed,the traffic signal control system designed based on PLC technology is used.The control of"24-hour automatic intelligent switching traffic light time setting"and the realization of the"urgent pass"function are put forward and solved on the premise of meeting the basic functions.A complete hardware wiring diagram and control program is given.The control system is debugged and operated by the self-made analog circuit.The system can not only reduce the congestion in peak period,but also reduce the waiting time in off-peak period and turn on the green light for emergency vehicles at any time,which can effectively improve the operation efficiency and management level of the traffic system and has achieved the expected design effect.
