【摘要】：随着城市建设步伐的不断加快，地铁以及一些路政建设造成了许许多多个临时路口，这催生了一个亟待解决的需求：无线智能交通灯。本文主要对此进行了设计和研究。本文首先对智能交通灯的研究现状进行综述，由此阐明其在现代交通控制领域的重要地位，进而提出了以单片机作为控制器的光伏无线智能交通灯的设计思想。为了更好的阐释本设计，本文对交通信号灯相关的研究背景和基础知识进行了相应的介绍。在此基础上设计的智能交通灯包括以下功能： 1、GPRS通信功能；使用AT指令控制GPRS模块与上位机建立数据连接并完成数据传输。 2、车流量预测和动态时间调整功能；在比较分析几种车流量预测方法的基础上对其中一种方法进行了改进，使其对车流量的预测具有更强的针对性。 3、人机交互功能；给系统制定了更人性化的应用平台，使人们能够更直观，更方便的了解交通灯运行的状态及路口状况。另外，本文还对系统包含的一些配套硬件设备进行了介绍和设计，包括温度传感器、LED交通灯驱动电路、车流量检测电路、光伏电池等。在本文的最后，完成了对系统的测试，结果证明系统可以完成稳定的数据传输，，预测结果准确，控制合理。
[Abstract]:As the pace of urban construction continues to accelerate, subway and some road construction have created many temporary intersections, which has given birth to an urgent need: wireless intelligent traffic lights.This article mainly carries on the design and the research to this.In this paper, the research status of intelligent traffic lights is summarized, and the important position of intelligent traffic lights in the field of modern traffic control is expounded, and then the design idea of photovoltaic wireless intelligent traffic lights with single chip microcomputer as controller is put forward.In order to better explain the design, this paper introduces the background and basic knowledge of traffic lights.The intelligent traffic lights designed on this basis include the following functions:Using AT command to control GPRS module to establish data connection and complete data transmission.2. The function of traffic flow prediction and dynamic time adjustment, one of which is improved on the basis of comparing and analyzing several methods of traffic flow prediction, which makes the forecast of traffic flow more pertinence.3. The human-computer interaction function, to make the system more humanized application platform, so that people can be more intuitive, more convenient to understand the state of traffic lights and intersection status.In addition, this paper also introduces and designs some supporting hardware devices, including temperature sensor LED traffic light driving circuit, traffic flow detection circuit, photovoltaic cells and so on.At the end of this paper, the system is tested, and the results show that the system can achieve stable data transmission, accurate prediction results and reasonable control.
