摘要

基于有源射频识别的应急车辆交通引导系统,采用基于ATmega16的车载主控制器和STM32交通灯控制器构成应急信息采集系统,并在上位机载入一个区域模型实现对交通的指示,存在系统处理过程耗时长的弊端。为此设计基于视觉传达的交通指示系统,系统总体结构包括预处理模块、交通指示信号灯检测模块、交通指示信号灯识别模块、交通指示信号灯跟踪模块和控制模块,系统采用红外遥控发射电路,通过红外遥控发射器发射6个持续信号,2个单次信号和8个独立通道编码,实现交通指示信号灯的选定、时间增减和急车强通等功能;对图像进行预处理和交通指示信号灯进行控制,加强系统的交通指示效果。实验结果表明,所设计系统能提升交通指示的效果,亮度处理过程仅需4 ms,显著缩短系统的耗时。
        The ATmega16 based vehicle-mounted master controller and STM32 traffic light controller are used to constitute the emergency information acquisition system,and a regional model is loaded in the upper computer to realize traffic instruction in the emergency vehicle traffic guidance system based on the active radio frequency identification(RFID),which causes a disad-vantage of long system processing process. Therefore,a traffic indicating system based on visual communication is designed. The overall structure of the system consists of the preprocessing module,and detection module,recognition module,tracking module and control module for traffic indicating signal lights. In the system,the infrared remote control emitting circuit is adopted. The selection,and time increase and decrease of traffic indicating signal lights,emergency vehicle forced passage,and other func-tions are realized by means of six continuous signals and two single-time signals emitted from the infrared remote control trans-mitter,and its eight independent channel codes,to execute image pre-processing and traffic indicating signal light control,so as to strengthen the traffic indicating effect of the system. The experimental results show that the designed system can improve the traffic indicating effect,and its brightness processing process takes only 4 ms,which significantly shortens the time-con-sumption of the system.
