智能公交系统电子站牌设计
摘 要：智能公交系统的建设可以提高人们出行对公共交通的选择，减少了私家车的使用，降低了环境污染，节约了能源的消耗，而且智能公交车运载量大，人均占用道路面积小，减小了城市拥堵问题，便利了人们的出行。本文主要对电子站牌的信息显示以及诸多方便乘客的功能进行研究，最终做到公交的智能化、信息化、以及调度安全精准化的目标。研究内容对智能电子站牌的整体方案设计，具体设计工作包括车载部分设计和站台部分设计。车载部分设计以单片机AT89C51为开发工具，并利用GPS为基础，将接收到的卫星信息进行处理，然后将数据通过无线发射模块发送给公交站牌。整个系统包括接收GPS信号、中心处理、数据的显示和无线发射四个模块。站台部分设计以单片机AT89C5l为开发工具，将接收到的来自无线数据接收模块发来的信息进行相应的处理，然后把一些信息通过数码管和发光二极管直观的显示出来。

Design of Electronic Station Card for Intelligent Bus System
Abstract：The construction of intelligent public transport system can improve people's choice of public transport, reduce the use of private cars, reduce environmental pollution, save energy consumption, and intelligent bus transport capacity is large. The per capita occupation of road area is small, reducing urban congestion and facilitating people's travel. This paper mainly studies the information display of electronic stop signs and the functions of many convenient passengers, and finally achieves the goal of intelligent, information and accurate dispatching safety. The whole scheme design of intelligent electronic station board is studied. The concrete design work includes vehicle part design and platform part design. The vehicle part design takes the single chip microcomputer AT89C51 as the development tool, and uses the GPS as the foundation, processes the received satellite information, then sends the data to the bus stop sign through the wireless transmission module. And the whole system includes four modules: receiving GPS signal, central processing, data display and wireless transmitting. Based on the AT89C5l of single chip microcomputer, the platform part designs the information received from the wireless data receiving module for processing, and then displays some information intuitively through digital tube and light-emitting diode.
