1、------------------------------------------------------------------------------------------------基于热释电的人体红外探测系统设计【摘要】本课题的主要内容是热释电在人体红外探测中的应用,最终落实到对热释电红外报警系统的开发。课题主要对五部分进行了探索研究,分别是光学设计部分,光电转换部分、处理电路部分、报警系统和控制显示系统,利用了应用光学、模拟电路、数字电路、单片机等学科的知识。涉及的知识面广,内容较多,但涉及的知识较浅,所以做
2、起来并不是很难。光学设计主要是针对菲涅尔透镜做了系统的设计,光电转换部分主要分析了热释电红外传感器的工作原理,并为其提供了适合电源。处理电路部分主要对BISS0001的外围接口进行了设计,使它能够正常有效的工作。报警系统主要是对蜂鸣器和发光二接管的电路进行了设计。控制显示系统主要对静态显示部分、软件部分、报警部分进行了设计。【关键词】热释电传感器AT89C51BISS000蜂鸣器Designofhumaninfrareddetectionsystembasedonpyroelectriceffect[Abstract]Th
