基亏AVR的太阳能高速公路智能电子显示屏系统设计

摘要

The design of a solar highway intelligent electronic display systems based on AVR is introduced, this design can be solved problems which exist in the LED display on the highway in the practical application of intelligent traffic management. The system uses ATMEGA8 to receive ultrasonic detection signal, and controls wireless transmitter module which send vehicle signal to ATMEGA128 control module.After receiving the wireless signal, the control module controls LED display and LCD display display real-time information. Experimental results show that the system is stable, real-time high, energy saving, environmental protection, with a good prospect.%针对LED电子显示屏在高速公路智能交通管理实际应用中存在着的问题，设计了一种基于AVR的太阳能高速公路智能电子显示屏系统。该系统采用单片机ATMEGA8接收超声波检测信号，并控制无线发送模块向ATMEGA128主控模块发送车辆有无信号，主控模块接收到无线信号后，控制LED点阵显示屏及LCD液晶显示屏实时信息显示。实验结果表明该系统性能稳定、实时性高、节能、环保、具有良好的应用前景。
