公交车的自动报站系统设计概述.docVIP

公交车自动报站系统设计城镇化发展非常迅速，城市快速膨胀，城市人口机动车增长来由此带来的城市交通拥堵问题非常严峻完善的是解决城市交通拥堵的最廉价方案，被国家大力扶持。国务院了优先发展公交系统的相关文件，公交车在城市交通中越来越大的作用。 实现公交运行时报站的智能化，为乘客提供高效、便捷的服务。能够到站能够显示到站信息。GPS （全球定位系统），以89C51单片机为和基础利用GPS获取位置信息AT89C51单片机智能整合处理信息，控制指令；ISD1700系列语音芯片实现语音JHD162A LCD液晶模块来显示到站信息，实现所有的结果利用protes进行仿真验证，可以达到预期公交车自动报站的功能实现公交车到站显示屏显示到站信息语音自动站名全程无需人工干预，实现全自动智能报站安全可靠。所采用的元件廉价系统可以长期稳定稳定，推广。，GPS89C51，JHD162 The bus stops system automatically ABSTRACT The urbanization in our country is developing very quickly. The city’s expansion is very quickly, the urban population increase sharply, The number of cars on the road is growing so fast. For the past few years, the city’s traffic congestion problem is very serious. City establish a perfect public transportation system is the cheapest solutions to urban traffic congestion. It is national energetical support. The state council issued the state council on priority to the development of urban public transportation guidance on December 29, 2012. The bus in the citys traffic occupies a more and more important role. This design aims to realize intelligent broadcasting station of bus information, provide efficient and convenient services for passengers. This design requirement system can automatic voice broadcast station information, and can display station information. This system USES the GPS (Global Positioning System Global Positioning System) with a 89c51 SCM as the core. This system uses GPS to obtain accurate vehicle location information. The use of 89c51 single-chip microcomputer to process information. Using ISD1700 to realize voice function. Though the JHD162A to display the information of stations. So as to realize the function of all. Using protest for the simulation and verification, the result of the design can achieve. The system fully without human intervention, and sage and reliable. This design uses the element is much cheaper. And the system can long-term and stable work, it is very suitable for promotion. KEY WORDS：automatically bro
