摘要
为了进一步提高十字路口的车辆通行效率,提出基于CAN总线的交通管理智能控制设计方案。该系统包括硬件控制模块、车流量采集模块、上位机软件等部分。硬件控制模块由主控模块、驱动模块、硬件黄闪模块等组成。主控模块与驱动模块之间采用CAN总线通信,具有通信速率高、可靠性好的优点。主控模块负责协调调度各个模块之间的工作;驱动模块负责驱动路口的信号灯及故障检测;车流量采集模块负责采集排队车流量数据,为智能配时提供依据。调试结果表明,该控制系统能够根据车流量智能调节车辆通行时间,提高车辆通行效率。
In order to further improve the efficiency of the vehicle at the crossroads,the intelligent control design scheme of traffic managementbased on CAN bus is proposed. The system includes hardware control module,traffic flow acquisition modu le, PC software and other parts.The hardware control module is composed of tlie main control module,the driving module and the hardware yellow flash module. The main con-trol module communicates witli the drive module using the CAN bus,with high communication speed,the advantages of good reliability. The main control module is responsilDle for coordinating the operation between the various modules ＆ the driving module is responsible for driving thesignal lights and fault detection at the intersection ; the traffic flow collecting module is responsible for collecting the queuing traffic data and providing the basis for the intelligent timing. The debugging results show that the control system can adjust the vehicle transit time according to the traffic flow and improve the vehicle traffic efficiency.
