基于单片机的公交车语音报站系统的设计 院 系:信息科学与工程学院 专 业 班:电子科学与技术 姓 名: 学 号: 指导教师: 2015年5月 基于单片机的公交车语音报站系统的设计 The Design of Bus Station Vioce Reporting System Based on MCU PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT IV 摘 要 设计一个带有语音播放的公交车报站系统以满足各类乘客需求。设置4个按键,系统实现第一站、下一站、停止报站、重新设置报站等功能。系统主要组成部分是STC89C52单片机、语音模块ISD4004、按键和LCD1602显示器。按键控制语音的播放,播放的信息在液晶显示器上显示,ISD4004语音模块存放要报站的信息。 系统硬件利用STC89C52作为CPU进行控制,利用ISD4004语音芯片的功能,烧录相应的程序显示相应的信息提示。利用LM386的功能进行站台语音的播出,同时利用LCD液晶显示器显示站台信息。 系统C语言编程完毕后烧录对应的芯片当中,然后用proteus进行仿真测试。 系统实现LCD的显示,ISD4004语音播报,红外控制中断服务程序都是通过软件keilC51进行C语言编程。为了系统的完善,把程序通过串口烧录到STC89C52中去,进行调试。 关键词:STC89C52单片机 ISD4004语音芯片 LCD1602显示器 Proteus 按键 Abstract In order to improve the quality of public transport services, to meet the needs of all kinds of passenger and bus station sound player for system design. The system can report the originating station, one stop before the function and station. The system is composed of AT89C51, ISD4004, voice module and a display button LCD1602. Station information stored in ISD4004 voice module. Voice playback, playback button control information is displayed on LCD. The design consists of six groups of test results show that the system is stable and reliable. To meet the design requirements. The system hardware using STC89C52 as the CPU for overall control, the establishment by ISD4004 voice chip voice information database, and a free combination of voice information to form a diverse voice message, voice message broadcast using LM386 amplifier and voice prompts. The system software uses the C programming language software keilC51, the system to achieve the LCD display, ISD4004 voice broadcast, infrared control program such as interrupt service routine, the procedure to go through the serial port writes STC89C52, repeated testing,to make the system perfect.
