引入单色OLED显示模块作为交通信号机的人机界面显示器,模块分辨率为128×64,具有16级灰度的文字和图片显示.所设计的显示控制方案采用ARM9作为处理芯片,可以嵌入科学的算法对交通流进行有效控制.该智能交通信号系统不但能够提供良好的人机界面,而且适应室外的恶劣环境,同时可以对交通流进行多相位、多时段控制.
OLED display module was used as a man-machine interface in the traffic signal system. In this design, the OLED display realizes the 128×64 pixels of picture and character monochrome display with 16 gray-scales. The intelligent traffic signal system with OLED display not only can provide good man-machine interface, and adapt to the harsh outdoor environment, but also can achieve multi-phase and multi-time control of traffic flow. The intelligent traffic signal system with OLED display uses the ARM9 as processor, so a scientific algorithm can be embedded in it to carry out effective control of traffic flow.
