本文采用了一款新型PCC作为主控制器进行智能交通控制系统的设计,根据十字路口交通灯的控制要求,采用PCC可编程序控制器和传感器相结合的一种智能控制方法,使用传感器采集车辆脉冲,用PCC高速计数器对脉冲进行计数,根据取得的数据运用智能控制原则自动调节红绿灯的时间长度,最大限度地减少车辆滞留现象,较好地解决了车量滞留问题。理论结果表明,该系统设计方案可以达到预期目标。
In this paper, a new type of PCC is adopted as the main controller to design the intelligent traffic control system. According to the control requirements of traffic lights at the crossroads, an intelligent control method combining PCC and sensors is used to collect the vehicles Pulse, use PCC high-speed counter to count the pulse. According to the data obtained, use intelligent control principle to automatically adjust the time length of traffic light, minimize the phenomenon of vehicle detention, and solve the problem of vehicle detention. Theoretical results show that the system design can achieve the desired goal.
