【摘要】：随着城市化进程的不断加快,城市人口数量急剧增加,大中城市的道路拥堵现象越来越严重,公交出行已经成为现代社会大部分人们出门方式的首选,同时,其发达程度也成为判断一个城市文明程度与信息化程度的重要参考标准。以往,每辆公交车上都配置一位售票员,为了提高效率,节约劳动力,本文在分析了现在市面上主流智能公交自动报站器的基础上,采用GPS定位技术,语音合成技术,以ARM主处理器为核心,提出了智能公交报站器的设计构思,来实现公交自动报站。首先,本文介绍了国内外智能公交的现状,并分析了智能公交系统的组成,引出了智能公交系统与GPS定位技术的关系,并对GPS的定义、组成、定位原理进行了详细的分析介绍。然后,对智能公交报站器的硬件和软件部分进行了分析设计,两部分都是先进行总体功能分析,然后对每一部分进行设计。硬件部分主要由GPS模块、ARM主处理器模块、自动语音报站模块组成,其中ARM主处理器模块包括ARM主芯片以及串口、LCD、ADC、SPI总线、RTC时钟、SD卡、FLASH、以太网等外围电路。本文对每一部分的功能电路进行了详细的设计,并介绍了主要模块的芯片选型。软件部分主要包括GPS数据的分析与处理、ARM主芯片的中断响应与数据比对、语音的自动报站。最后,本文完成了系统硬件和软件两部分的测试工作,其中软件部分测试工作主要有三点,其一：GPS数据能否进行正常的接收,其二：GPS数据接收之后能否进行正常的经纬度转换并进行显示,其三：当经纬度坐标匹配时,智能公交报站器能否进行正常的自动语音报站。经过测试,上述3部分功能都能很好的实现。
[Abstract]:With the rapid development of urbanization, the number of urban population increases rapidly, and the road congestion in large and medium-sized cities becomes more and more serious. Public transportation has become the first choice for most people to go out in modern society, at the same time, Its level of development has also become an important reference standard for judging the degree of civilization and informatization in a city. In the past, a conductor was deployed on every bus in order to improve efficiency and save labor. Based on the analysis of the mainstream intelligent bus automatic station reports in the market, this paper presents the design idea of the intelligent bus stop report device using GPS positioning technology and voice synthesis technology, taking the ARM main processor as the core. To achieve automatic bus stop. First of all, this paper introduces the current situation of intelligent public transport at home and abroad, and analyzes the composition of intelligent public transport system, leads to the relationship between intelligent public transport system and GPS positioning technology, and defines and constitutes the GPS. The principle of positioning is analyzed and introduced in detail. Then, the hardware and software of the intelligent bus station are analyzed and designed. The two parts are analyzed first, and then each part is designed. The hardware is mainly composed of GPS module and arm main processor module. The ARM main processor module includes the ARM main chip, the serial port LCD-ADCU SPI bus, the RTC clock and SD card flash, Ethernet and other peripheral circuits. In this paper, the functional circuits of each part are designed in detail. The software includes the analysis and processing of GPS data, the interrupt response and data comparison of arm main chip, and the automatic voice station. Finally, this paper has completed the system hardware and software two parts of the test work, the software part of the test work has three main points, first, whether the GPS data can be received normally, The second is whether the normal latitude and longitude conversion can be carried out after receiving the GPS data. Third, when the coordinates of latitude and longitude are matched, can the intelligent bus station report station carry out the normal automatic voice reporting station. After testing, The above three parts of the function can be achieved very well.
