摘 要 随着城市交通的快速发展，公交汽车为外出的人们提供了方便快捷的服务。而公交汽车的报站共识直接影响其服务的质量。传统报站方式是由乘务人员进行人工报站，该方式因其效果太差和工作程度太大，在很多大城市已经被淘汰。近年来，微机技术与各种语音芯片相结合，即可完成语音的合成技术，使得公交车报站器的实现成为可能，从而为市民提供了更加人性化得服务。公交应用系统带给公交企的将不仅是形象的提升，也是效益的增长。本文介绍了一种公交车报站器的系统设计原理，提出了以61单片机为核心，通过4*4键盘获取外部指示以控制SPR4096语音芯片电路以及LCD显示的硬件设计和软件设计方案。该系统语音音质好，功能强，成本很低，是提供公交服务的一种较好的手段。本文首先介绍了SPCE061A的基本原理和开发方法，讨论了控制模块、显示系统和存储系统的总体设计思想和实现方案，并且详细阐述了硬件系统和软件系统的设计。硬件系统包括电源电路、控制电路、信息存储电路、显示电路、语音资源存储电路等；硬件驱动程序由开发系统提供的汇编语言库函数来实现。经过调试和仿真运行，使系统最终达到了课题设计的要求。 关键词：单片机，语音处理，LCD显示，SPR4096 Abstract With the rapid development of urban traffic, transit buses out for people with a quick and convenient services. But the consensus transit buses stops directly affects its quality of service. Traditional way is by the crew stops artificial stops for its effect, this way poor and working level too big, in many big cities have been eliminated. In recent years, with various pronunciation chip microcomputer technology, can complete combined speech synthesis technology, makes the realization of bus stops device becomes possible, and thus for citizens to provide a more humanized service. Bus application system will not only bring bus enterprises, but also is of image promotion of growth. Benefit This paper introduces a kind of bus stops the system design principle, is put forward to 61 single chip, through 4 * 4 keyboard access external SPR4096 pronunciation chip instruction to control circuit and LCD display hardware design and software design. This system voice timbre, the function is strong, very low cost, is to provide the bus service is a good method. This paper firstly introduces the basic principle and development SPCE061A methods are discussed in control module, display systems and storage system design thinking and realize the overall solution, and illustrates the hardware and software system design. Hardware systems include power supply circuit, control circuit and information storage circuit, display circuit, speech resources st
