However, the means of crime elements are also continuously progressing. Obviously, the traditional means of security can not meet peoples needs.The article introduces a design of Laboratory Anti-theft alarm system. The system used AT89C51 microcontroller as the core of control, used heat spread infrared rays sensor as sensor, used automatic dial-up system as alarm. It is simple, inexpensive and easy to be operated, anti-interference capability and secure, and the automatic dial-up alarm function can be used into laboratory and family as the alarm system.Keywords: microcontroller, alarm, automatic dial-up, sensor 第 PAGE \* MERGEFORMAT III页 共Ⅲ页目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263682692 1 引言 PAGEREF _Toc263682692 \h 1 HYPERLINK \l _Toc263682693 1.1 本课题的研究意义 PAGEREF _Toc263682693 \h 1 HYPERLINK \l _Toc263682694 1.2 防盗报警系统的研究状况以及发展动态 PAGEREF _Toc263682694 \h 1 HYPERLINK \l _Toc263682695 2 系统总体介绍 PAGEREF _Toc263682695 \h 3 HYPERLINK \l _Toc263682696 2.1 入侵探测器介绍 PAGEREF _Toc263682696 \h 3 HYPERLINK \l _Toc263682697 2.1.1 红外探测器 PAGEREF _Toc263682697 \h 3 HYPERLINK \l _Toc263682698 2.1.2 微波探测器 PAGEREF _Toc263682698 \h 5 HYPERLINK \l _Toc263682699 2.1.3 玻璃破碎探测器 PAGEREF _Toc263682699 \h 6 HYPERLINK \l _Toc263682700 2.1.4 电容变化探测器 PAGEREF _Toc263682700
