摘 要
室內(nèi)防盜檢測(cè)系統(tǒng)作為一種新型的電子防盜設(shè)備廣泛應(yīng)用于家庭住宅區(qū)。目前市面上所擁有的家庭電子防盜報(bào)警器，只能用于單一的住宅，不利于統(tǒng)一管理，而且也不能滿足現(xiàn)代住宅區(qū)的發(fā)展要求，所以很有必要對(duì)家庭電子防盜器進(jìn)一步完善和提高。
本文提出了一種基于單片機(jī)信號(hào)處理技術(shù)的防盜檢測(cè)器的軟硬件設(shè)計(jì)方法。應(yīng)用該方法設(shè)計(jì)的系統(tǒng)在反應(yīng)速度、誤報(bào)率、漏報(bào)率以及抗干擾能力方面都具有較好性能。本系統(tǒng)利用熱釋電紅外傳感器的紅外輻射與紅外探測(cè)的原理，設(shè)計(jì)的新型探測(cè)器，測(cè)量范圍廣, 響應(yīng)速度快, 靈敏度高，抗干擾能力強(qiáng)，安全可靠 。并采用單片機(jī)89C51作為人體探測(cè)系統(tǒng)的核心，以熱釋電紅外線為數(shù)據(jù)采集部件，經(jīng)過(guò)比較放大之后，輸入單片機(jī)進(jìn)行數(shù)據(jù)判斷及處理。當(dāng)檢測(cè)到有被測(cè)物體進(jìn)入測(cè)量范圍時(shí)，系統(tǒng)自動(dòng)發(fā)出聲光報(bào)警信號(hào)，等待一段延遲時(shí)間后自動(dòng)消除報(bào)警信號(hào)，并可手動(dòng)解除報(bào)警信號(hào)。當(dāng)有主人在家系統(tǒng)無(wú)需報(bào)警時(shí),可開啟樓道燈控制系統(tǒng)，即傳感器探測(cè)到有人經(jīng)過(guò)時(shí)照明燈亮,等待一段延遲時(shí)間后自動(dòng)熄滅,并可手動(dòng)來(lái)控制延遲時(shí)間的長(zhǎng)短。系統(tǒng)的另外一個(gè)功能是檢測(cè)人數(shù)及最大容量人數(shù)控制，當(dāng)探測(cè)頭探測(cè)到有人經(jīng)過(guò)時(shí),系統(tǒng)自動(dòng)計(jì)數(shù)加一，并可以通過(guò)鍵盤控制最大容量人數(shù)，如果探測(cè)到的人數(shù)超過(guò)最大容量人數(shù)時(shí)則發(fā)出自動(dòng)報(bào)警信號(hào)，并通過(guò)LED顯示檢測(cè)到的人數(shù)與最大容量報(bào)警人數(shù)。系統(tǒng)使用單片機(jī)與PC機(jī)通信原理，把采集到的數(shù)據(jù)傳輸給計(jì)算機(jī)統(tǒng)一處理。

Abstract: Room theft-proof detection system guards against theft and has an extensive equipment to apply the residential area of the family as a kind of new-type electron. The electronic burglar alarm of family that has on the market at present, can only be used in the single house, unfavorable to managing in unison, and can not meet the development request of the modern residential area either, so it is very necessary to perfects and improves the electronic burglary-resisiting device of family further.
This text has put forward a kind of software and hardware design method of theft-proof detection based on signal treatment technology of the one-chip computer. The system using this method to be designed has better performance in reaction speed, wrong report rate, rate of failing to report and anti-interference ability . This thesis main content is as follows:
By using a pvroelectric infrared sensor，the author of this paper invented a new kind of detector which increases the sensitivity and signal-to-noise ratio as well as the capacity of anti-Interference of this kind of instrument ; therefore，this new kind of detector is of practical use.Adopt one-chip computer 89C51 survey systematic core as the human body, fever for Israel clear up electric infrared ray gather the part for datum, after relatively enlarging, input the one-chip computer and judges data and deals with. When measuring to has testees to enter the range of measuring, the system gives out mere alarm signal once automatically, and can remove the alarm signal manually . 4. Show number of people and large capacity warning number most got to measure through LED , at the same time can change the large capacity warning number most with keyboard. The system uses the one-chip computer and communication principle of PC , the data transmission that gets gathering is dealt with in unison for the computer.
