沈阳工学院 毕业设计报告 题 目: 基于单片机的车速控制 语音报警系统的设计与实现 院 系: 信息与控制学院 专 业: 班级学号: 学生姓名: 指导教师: 成 绩: 2014 年 06 月 25日 摘 要 本文通过对近年来因车速过快而引起各种交通事故的分析与研究,设计了一种基于单片机的车速控制语音报警系统。 本系统主要研究并设计了基于STC89C52单片机的车速控制电路、语音报警电路、按键电路、电源电路和LCD1602显示电路,编写了相应的车速控制语音报警系统程序。本文详细阐述了基于单片机STC89C52的车速控制电路、语音芯片ISD1820、 LCD1602、按键电路和电源电路的原理及应用,介绍了车速控制语音报警系统程序的编写思想,并最终达到车速控制语音报警的目的。 本文提出的基于单片机的车速控制语音报警系统和以往单纯的车速控制或语音报警系统相比具有结构简单、可靠性高和成本低廉等优点,使本系统不但可以车速控制语音报警系统单独使用,还可以与其他电路配合组成车辆自动驾驶系统使用,应用前景广泛。 关键词:单片机;车速控制;语音报警 Abstract This article design a speed control voice alarm system which is based on a single chip and the analysis and research in recent years. This system was account on the control circuit speed of the STC89C52 microcontroller, voice alarm circuit , key circuit, power supply circuit and LCD1602 display circuit , and then designed produce of the corresponding speed control voice alarm system program . This paper describes STC89C52 microcontroller which based on speed control circuit , principle and application of voice chip ISD1820, LCD1602, the principle and practice of the key circuit and power supply circuit,introduce the voice alarm of the speed control procedures for the preparation of systems thinking . At last it will achieve the purpose of controlling the speed throughthe voice alarms. This article presents a microcontroller that based on speed control of voice alarm systems and past simple speed control or voice alarm system compared with the simple structure is higher reliability and lower cost, and so on .so that this system not only control the speed of the voice alarm system alone , but also composition of the vehicle and used with other circuits autopilot systems , ultimately it must has a application prospect.
