西南科技大学 毕业设计（论文） 题目名称：防火防盗报警系统的硬件设计 防火防盗报警系统的硬件设计 摘要：安全防范技术涉及到社会的方方面面，是保护国家和人民利益与安全的重要手段。随着。本文智能化中的防盗防火报警系统硬件部分的设计。确定硬件系统的整体设计方案，采用模块化设计，确定各个模块的器件，设计制作各模块的电路，搭建出整个硬件系统，通过整机调试，给出调试结果。智能化防盗防火报警系统集防盗防火功能于一体，可实现自动检测与自动报警。采用红外探测与微波探测器构成的双鉴探测器实现盗情检测；用温度探测器、感烟探测器和一氧化碳探测器集为一体的复合式火灾探测器来完成火情检测。本系统通过密码来识别主人身份，系统开启后只有输入正确的密码才能关闭系统。该系统同时采用看门狗集成芯片实现自诊断功能，出现故障能自动进行处理。系统从硬件和软件两方面进行了抗干扰设计，使其具有较好的抗干扰能力，完成系统可靠工作。 关键词：防火；防盗；报警系统 The Hardware Design of an Alarm System of Fireproof and Theft-proof Abstract: The safety-defending techniques are involved in most aspects of the society and they are very important in protecting the benefit and security of people and country. Hospital facilities have gradually improved as the economy improving in china. Many hospitals have invested the expensive medical equipment, and the construction in the hospital improved a lot, so it needs to ensure the safety of medical equipment and prevent fire. The hardware of an intelligent alarm system for hospital is introduced. The overall project of the system was designed adopting modular design. The element of every module was confirmed. The circuit of every module was given, a hardware system was set up and debugged and the test result was given. The system includes the functions of theft-proof and fireproof, performing automatic detection. Pyroelectric infrared sensor combined Microwave sensor is used for theft-proof to carry out automatic detection. Temperature sensor, Smoke sensor and CO sensor are integrated to a compound detector for fireproof. The system discerns the master by the secret code. Only imput correct secret code could the system be closed. The system was automatic watched by Watch-dog IC, and was designed by considering the anti-interference in the side of the hardware and software. It can work with high reliability. Key words: fireproof，theft-proof，alarm system 目 录 1章 绪 论 1 1.1 概述 1 1.2 本课题主要工作概述 2 1.3 论文结构 3 第2章 系统总体设计方案 4 2.1 系统总体构成 4 2.2 报警系统的功能和工作过程 5 第3章 防盗探测器设计与实现 7
