1、石家庄铁道大学四方学院毕业设计家用红外现场报警的设计Household Infrared Alarm at the Scene Design摘 要红外线波长为 0.761.5 微米，是众多不可见光的一种，具有较强的穿透能力，还具有隐蔽性，正是这个原因才使红外线在报警系统中有了很广泛的应用。随着人们生活的提高，安全对人们的生活越显的重要，所以红外报警对提高人们的生活质量有着重要意义。本设计是基于单片机和红外模块的报警器的设计，对系统软件设计和硬件实现进行了详细的描述，本设计已包括 STC89C52 单片机构成的核心控制元件，2401 遥控模块，红外模块发出红外线，报警器四部分组成。报警器工作时由
2、发射端发出红外线，正常情况下接收端接收不到红外线，不发生报警，当有人时，红外线被遮挡被发射，接收端接收到反射回来的红外线，通过单片机驱动蜂鸣器发生报警。当家人遮挡红外线时，通过按遥控按键使发射端停止发射红外，此时不发生报警，从而实现了家用红外报警器的设计。家用红外报警器广泛应用于商场，家庭等地。本设计运行稳定，硬件电路简单，成本低，具有一定的实用性。关键词：单片机红外对管无线遥控蜂鸣器Abstract Infrared wavelength of 0.76 to 1.5microns, is one of the many invisible light one, has a strong p
