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 microputer technology, can plete bined speech synthesis technology, makes the realization of bus stops device bees 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 storage circuit, etc.。硬件系統(tǒng)包括電源電路、控制電路、信息存儲(chǔ)電路、顯示電路、語(yǔ)音資源存儲(chǔ)電路等；硬件驅(qū)動(dòng)程序由開發(fā)系統(tǒng)提供的匯編語(yǔ)言庫(kù)函數(shù)來(lái)實(shí)現(xiàn)。該系統(tǒng)語(yǔ)音音質(zhì)好，功能強(qiáng)，成本很低，是提供公交服務(wù)的一種較好的手段。 公交應(yīng)用系統(tǒng)帶給公交企 的將不僅是形象的提升，也是效益的增長(zhǎng)。傳統(tǒng)報(bào)站方式是由乘務(wù)人員進(jìn)行人工報(bào)站，該方式因其效果太差和工作程度太大，在很多大城市已經(jīng)被淘汰。公交車報(bào)站器 I 摘 要 隨著城市交通的快速發(fā)展，公交汽車為外出的人們提供了方便快捷的服務(wù)。而公交汽車的報(bào)站共識(shí)直接影響其服務(wù)的質(zhì)量。近年來(lái)，微機(jī)技術(shù)與各種語(yǔ)音芯片相結(jié)合，即可完成語(yǔ)音的合成技術(shù)，使得公交車報(bào)站器的實(shí)現(xiàn)成為可能，從而為市民提供了更加人性化得服務(wù)。 本文介紹了一種公交車報(bào)站器的系統(tǒng)設(shè)計(jì)原理，提出了以 61 單片機(jī)為核心，通過(guò) 4*4 鍵盤獲取外部指示以控制 SPR4096 語(yǔ)音芯片電路以及 LCD 顯示的硬件設(shè)計(jì)和軟件設(shè)計(jì)方案。本文首先介紹了 SPCE061A 的基本原理和開發(fā)方法，討論了控制模塊、顯示系統(tǒng)和存儲(chǔ)系統(tǒng)的總體設(shè)計(jì)思想和實(shí)現(xiàn)方案，并且詳細(xì)闡述了硬件系統(tǒng)和軟件系統(tǒng)的設(shè)計(jì)。經(jīng)過(guò)調(diào)試和仿真運(yùn)行，使系統(tǒng)最終達(dá)到了課題設(shè)計(jì)的要求。 Hardware driver by the development of the system provided assembler language library function to realize. After testing and simulation operation, the system finally achieved the topic design requirements.
