（ 20 11 届） 毕业设计（论文） 题 目：基于红外线报警及自动拨号家居防盗系统的设计 姓　　名：　　 　　　　　　　　　　　　 专　　业：　　 电子信息工程 　　　 班　　级：　　　　 关键词：人体热释电红外传感器，AT89C52单片机，自动拨号 Based on infrared alarm and automatic dial-up household anti-theft system design Abstract Along with the science and technology unceasing development and continuous improvement of peoples living standard, people to the private property protection means has been enhanced to guard against theft facilities, and puts forward new requirements. This paper introduces the AT89C52 single chip computer, and based on human pyroelectric infrared sensor and telephone interface combination, through software programming, realize circuit function. Required to exploit the infrared sensors, realize once intruders surveillance area, a buzzer alarm, telephone automatic dial-up. This paper gives hardware and software design of concrete realization method. Currently used in China are the basic types of anti-theft alarm with ultrasonic, active infrared transmitter / receiver and microwave technology-based. Here, we use human pyroelectric infrared sensor to design anti-theft alarm system. The pyroelectric infrared sensor can detect the infrared radiation the human body, and convert them to electrical signals at the same time, it can identify the movement of biological and other non-biological.
