摘 要
室內(nèi)防盜檢測系統(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，所以很有必要對家庭電子防盜器進一步完善和提高。
本文提出了一種基于單片機信號處理技術(shù)的防盜檢測器的軟硬件設(shè)計方法。應(yīng)用該方法設(shè)計的系統(tǒng)在反應(yīng)速度、誤報率、漏報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的原理，設(shè)計的新型探測器，測量范圍廣, 響應(yīng)速度快, 靈敏度高，抗干擾能力強，安全可靠 。并采用單片機89C51作為人體探測系統(tǒng)的核心，以熱釋電紅外線為數(shù)據(jù)采集部件，經(jīng)過比較放大之后，輸入單片機進行數(shù)據(jù)判斷及處理。當(dāng)檢測到有被測物體進入測量范圍時，系統(tǒng)自動發(fā)出聲光報警信號，等待一段延遲時間后自動消除報警信號，并可手動解除報警信號。當(dāng)有主人在家系統(tǒng)無需報警時,可開啟樓道燈控制系統(tǒng)，即傳感器探測到有人經(jīng)過時照明燈亮,等待一段延遲時間后自動熄滅,并可手動來控制延遲時間的長短。系統(tǒng)的另外一個功能是檢測人數(shù)及最大容量人數(shù)控制，當(dāng)探測頭探測到有人經(jīng)過時,系統(tǒng)自動計數(shù)加一，并可以通過鍵盤控制最大容量人數(shù)，如果探測到的人數(shù)超過最大容量人數(shù)時則發(fā)出自動報警信號，并通過LED顯示檢測到的人數(shù)與最大容量報警人數(shù)。系統(tǒng)使用單片機與PC機通信原理，把采集到的數(shù)據(jù)傳輸給計算機統(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.
