摘要
当前,随着经济的发展,人民的生活日益改善,人们对家庭生命财产安全越来越重视,并采取了许多措施保护家庭的安全。以往的做法是安装防盗门、防盗网,但也存在有碍美观、不符合防火要求、不能有效防止坏人的入侵等缺点。
     目前,市场上存在着各种各样的家居安防、防火防盗报警系统,系统误报率较高、可靠性比较差。
     鉴于此,本课题旨在设计出一种低误报率、可靠性高的智能住宅安全防范系统。它集防火防盗功能于一体,可实现自动检测与自动电话拨号报警。此次设计以MCS-51系列单片机AT89S51为核心,结合外围无线编码接收电路、数字语音录放电路、通话电路,以及其它的一些外围辅助电路,构成了一款高性能的智能无线安防报警器。其中,红外探测器及微波探测器实现盗情报警;以温度探测器和光电感烟探测器集为一体构成的复合式火灾探测器可完成火灾报警。而且本系统分别从硬件和软件两方面进行了抗干扰设计,提高了系统的抗干扰能力。该系统实现了低误报率,增强了系统的可靠性。
Presently, along with the economical development, people's life improves day by day, the people take seriously more and more to the family personal safety and property, and has adopted many measure protection family security. The former procedure is the installment burglar-proof door, the security net, but also exists obstructs artisticly, does not meet the fire protection requirement, not to be able to prevent unprincipled person's shortcomings effectively and so on invasion.
     At present, in the market exists variously lives at An Fang, the fire protection security alarm system, but they are mostly by part constitutions and so on traditional sensor and program control installment, the system rate of false alarm is high, the reliability to be quite bad.
     In view of this, this topic is for the purpose of designing one kind of low rate of false alarm, the reliable high intelligence housing safety and protection system. Its collection fire protection security function in a body, may realize the automatic detection and the dial telephone digit dialing warning. This design take MCS-51 series monolithic integrated circuit AT89S51 as a core, unifies the periphery wireless code reception electric circuit, the digital pronunciation recording and sending out electric circuit, the speech circuit, as well as the other periphery auxiliary circuit, constituted section of high performance intelligent wireless peaceful against alarm apparatus. And, the infrared acquisition aid and the microwave detector realize rob the sentiment warning; As the compound expression fire detector which a body constitutes may complete the fire warning take the temperature detector and the optical detector of fire smoke collection. This multi-sensor's application has realized the low rate of false alarm, strengthened system's reliability. Moreover this system separately has carried on the antijamming design from the hardware and the software two aspects, sharpened system's antijamming ability.
