基于单片机技术电话拨号防盗报警器的设计毕业综合实践.doc

PAGE 2 PAGE 1 毕业综合实践 课题名称：基于单片机技术电话拨号防盗报警器的设计 系 部： 电子工程系 摘要 本设计由单片机控制器、键盘输入、数码管显示、触发电路、拨号电路、及电源等6个部分组成，单片机控制器是整个系统的核心，负责控制检测输入/输出显示、模拟摘机、拨号报警、挂机等一系列的程序动作，并采用小引脚，高性能，低价位的AT89C2051。 键盘输入电路负责输入单片机中一系列工作参数及功能设定。发光二极管数码管显示器在整个系统工作过程中充当一个简单的人机界面，用以显示工作状况及输入/输出的数据等。电话拨号防盗报警器的触发电路用磁性开关，简单可靠，报警器采用隐蔽安装，防止小偷发现。拨号及报警电路来完成模拟摘机、拨号、发出报警音、挂机等工作过程，由单片机控制。电源部分负责整个系统供电。设计目标要求实现对盗情的感知，并在一定的时间范围内，向手机或者电话发送报警。对方接通电话后，即可听到报警音，达到拨号报警的目的。 关键词 :单片机，电话拨号，防盗报警，自动报警系统 Abstract This design by single-chip microcomputer controller, keyboard input, digital tube display, trigger circuit, dial-up circuit, and power supply, six parts, microcomputer controller is the core of the whole system, is responsible for the control test input/output display, simulation pick machine, dial-up alarm, hang machine, and a series of procedures movement, and the XiaoYin feet, high performance, low price of AT89C2051. The keyboard input circuit is responsible for a series of working parameters input single chip microcomputer and function setting. Leds digital tube display in the system in the process of work as a simple interface to show work situation and input/output data etc. Dialing and alarm system of trigger circuit with magnetic switch, simple, reliable and alarm the hidden installation, prevent the thief found. Dial-up and alarm circuit to complete simulation pick machine, dial, alarm sound, hang up and work process, from single chip microcomputer control. The power is in charge of the whole system of power supply. Design goals to achieve the perception of the stolen feeling, and in certain time range, mobile phone or phone to send the police. Connect each other, can be heard the alarm sound, to achieve the purpose of dial-up alarm. Key words: a single-chip microcomputer, dialing, anti-theft alarm, automatic alarm system 目录 摘要……………………………………………………………………………………3 1课题分析 1.1方案提出及准备………………………………………………………………4 1.2方案的选择……………………………………………………………………5 2 系统的设计 2.1设计思路……………………………………………
