文档介绍：危险气体检测和防盗报警器的设计
Design of hazardous gas examination and burglar alarm
摘要
随着我和生活方式都发生了很大的变化。社区已成为现在城市的重要组成单元,虽然,小区的管理越来越科学规范,但是,只靠物业管理的保护是不够的,人们更关心自己家居和财产的安全。如今,人们生活水平还是存在着很大的差异,本设计是基于满足众多普通家庭安全需要的一款性能可靠、实用性强、灵敏度高、使用方便的有害气体检测和声光报警装置。
本设计主要由三大模块组成:信号检测和处理模块、无线发射和接收模块,和显示报警模块。采用气体传感器,检测家庭中经常接触到的气体,如天然气、煤气、液化气等有害气体;防盗器采用被动式热释电红外探测器;无线发射和接收模块完成对处理信号的编码、发射、接收和解码工作,实现远距离检测的目的。报警和显示模块采用单片机控制,不仅可以精确的显示对报警位置,而且具有数字时钟的功能。
本设不仅具有成本低、低功耗、性能可靠的优点,在技术上还可以利用GSM网络,实现GSM短信的智能远程报警及控制,通过手机终端接收报警短信,并且可以发送命令短信异地遥控实现各种操作。

ABSTRACT
Along with our country national economy swift development, people's living standard and the life style has had the very big change. munity has e now the urban position unit, although, the plot management is getting more and more standard and the science, but, only depends on the estate management the protection is insufficient, the people cared that they live at with the property security. Now, the people living standard has this very big difference, but the high-end warning often needs to turn on work, therefore the price is also quite expensive. In order to satisfy the numerous ordinary families the safety requirements, thus this design is based on a practical section of perform reliably, the sensitivity is high, easy to operate family alarm apparatus, use for to examine the hazardous gas and the burglar alarm.
This design is posed of three big modules: The signal detection and the processing module, the wireless launch and the receive module, the obviously report and the display module. Uses the gas sensor, mainly examines the gas like natural gas which, the coal gas, the liquid gas in the family may contact and so on noxious gas; Security uses the passive form pyroelectric infrared acquisition aid; The wireless launch and the receive plete to process the signal the code, the launch, the receive and the decoding work, completes the long-distance range examination the goal. The warning and the display
