电子与信息工程学院 本科毕业设计论文题目 对射式红外线防盗报警器的设计所属院部 电子与信息工程学院 专 业 电子信息科学与技术 2024 年 5 月摘 要本系统是基于 AT89S52 单片机控制的红外线防盗报警器,主要由红外线发射部分、红外线接收部分、单片机以与声光报警部分组成。可通过发射电路发射的红外线被遮挡时控制报警系统报警, 通过单片机控制报警电路的运行,并能同时进行声光报警,用红外线收发管进行检测,安装隐蔽,不易被发现;探测信号采纳脉冲信号,节能且抗干扰。系统可以探测到一定围的人的闯入, 可以应用在安防围比较确定的情况下。采纳这种方法设计的防盗报警器具有成本廉价和探测效果好的优点,有着宽阔的市场前景。关 键 词:单片机;红外线防盗报警器;声光报警ABSTRACTThe system is a infra-red anti-theft alarm controled by single-chip AT89S52, including infra-red part of the launch, part of the infrared receiver, microcontroller, as well as part of sound and light alarm.The system will alarm when infrared ray has been blocked , through the single-chip microcomputer to control the operation of alarm circuit, and at the same time sound and light alarm, with infrared transceiver test tube, install hidden, can not easily be found; detection signal using pulse signal, energy-saving and anti-jamming. This system can detect a certain person within the scope of the intrusion, security can be applied to determine the scope of the case. Designed using this method of anti-theft alarm and detection in a cost-effectiveness of low-cost best advantages, has broad market prospects.KEY WORDS: Single chip microcomputer;Infrared anti-theft alarm; Sound and light alarm目 录1 绪论 11.1 课题讨论的意义 11.2 课题讨论的目的 12 总体设计方案 33 硬件电路各部分电路设计 53.1 单片机控制系统电路 53.1.1 主控芯片的性能以与标准功能 53.1.2 主控芯片的主要结构与引脚功能 63.1.3 单片机控制部分电路 83.2 红外线发射电路 83.3 红外线接收电路 93.4 声光报警电路 103.5 电...
