摘要
针对早晚高峰期道路单向拥堵问题,设计移动隔离护栏潮汐车道。利用高功率远距离无线模块实现各子护栏组网功能,采用有限状态机协同各子隔离护栏同步移动,实现对潮汐车道调度与控制。针对各子隔离护栏移动定位问题,采用Canny边缘算子对车道线进行识别,并同步驱动各子护栏步进电机,使护栏移动到准确位置。利用安装在每个子护栏上的超声波传感器对车辆和行人进行探测,保护系统和行人安全。试运行结果表明,该系统使车道通行能力提升12.1%,平均车速提高29%,交通运行效率得到提高。
In order to solve the problem of one-way congestion of roads in the morning and evening rush hours,a tidal lane with mov⁃ing partition fence is designed.The high-power wireless module is used to realize the networking function of each sub-fence,and the finite state machine is used to cooperate with the synchronized movement of each sub-fence to realize the scheduling and control of the tidal lane.To solve the problem of the positioning of each sub-fence,the Canny edge operator is used to recognize the lane line,and the stepper motors of each sub-fence are synchronously driven to move it to an accurate position.Ultrasonic sensors mounted on each of the sub-fences detect obstacles around them,so that the safety of the system and pedestrians are protected.The results of the trial oper⁃ation show that the designed system has improved the traffic capacity of the lane by 12.1%and the average speed by 29%,which im⁃proves the efficiency of the urban transportation operation system.
