摘要
提出一种无线智能交通监控系统设计方案,采用电感线圈与单片机测量十字路口的车流量,将测得的数据通过短距离无线通信模块传输给嵌入式主控制器,由其动态调节各路口的红绿灯时长。值班人员通过嵌入式系统对十字路口进行远程视频监控,采用主动式R FID技术检测经过十字路口的应急车辆,必要时为其开启绿色通道。设置盲人提醒音,用不同频率的信号音告知盲人红绿灯状态;根据过马路的行人数量动态调整非十字路口红绿灯时长;系统电源则可在太阳能和市电间灵活切换。实验证明,系统可实现平安交通、效率交通、民生交通和绿色交通,对实际交通系统建设有一定的参考价值。
This paper proposes a design scheme of wireless intelligent transportation monitoring system, this system adopts the inductive loop and the single chip microcomputer to measure the traffic at the crossroads, and it transmits measured data via the short distance wireless communication modules to the embedded main controller, which is able to adjust the intersection traffic lights dynamically. Through the embedded system, the operation can remote video monitor the crossroads, and use active RFID technology to detect tile vehicle at the crossroads, then open the green channel for them when necessa~. It can set the blind reminder sound, uses different frequency tones to inform the blind person the traffic light status, and adjust the non crossroads traffic lights dynami- cally by the number of pedestrians crossing the road. The system power supply can be easily switched between the solar energy and the city electricity. The experiment proves that this system can realize safe transportation, efficient transportation, people＇s livelihood transportation and green transportation, and it has certain reference value to construct the actual transportation system.
