摘    要

 報(bào)警探測(cè)器作為傳感探測(cè)裝置，用來(lái)探測(cè)入侵者的入侵行為及各種異常情況。在各種各樣的智能建筑和普通建筑物中需要安全防范的場(chǎng)所很多。這些場(chǎng)所根據(jù)實(shí)際情況也有各種各樣的安全防范目的和要求。本次設(shè)計(jì)中，采用 PIR傳感器對(duì)外界進(jìn)行數(shù)據(jù)采集，以MSP430單片機(jī)為硬件電路的核心，研制移動(dòng)探測(cè)器系統(tǒng)，開(kāi)發(fā)出對(duì)周?chē)�環(huán)境中物體的監(jiān)測(cè)，通過(guò)報(bào)警顯示。
 論文首先闡述了移動(dòng)探測(cè)器系統(tǒng)的發(fā)展及現(xiàn)狀，通過(guò)對(duì)傳感器的分析確立了系統(tǒng)的研發(fā)方向接著介紹了系統(tǒng)的設(shè)計(jì)要求，由于探測(cè)器系統(tǒng)的工作環(huán)境較復(fù)雜，所以，此系統(tǒng)應(yīng)有防護(hù)設(shè)置。在此基礎(chǔ)上，闡述了系統(tǒng)的硬件電路設(shè)計(jì)與系統(tǒng)軟件設(shè)計(jì)及實(shí)用分析。
 本課題采用具有較高性?xún)r(jià)比的單片機(jī)MSP430構(gòu)成系統(tǒng)的核心部分，根據(jù)傳感器測(cè)量的信號(hào)，實(shí)現(xiàn)對(duì)移動(dòng)物體的識(shí)別和測(cè)量，并能對(duì)外界做出反應(yīng)。

Design of a Motion Detector Using MSP430
Abstract

As a detector alarm sensor detection device to detect intruders and various acts of invasion of anomalies. In a wide range of intelligent building and the generalsecurity buildings in need of a lot of places. According to the actual situation of these establishments have a wide range of security objectives and requirements. This, in the design, use of PIR sensors collects the data of out environment, to MSP430 MCU hardware circuits for the core, developed mobile detector system, developed in the objects on the surrounding environment monitoring, through the alarm display.     First of all the papers on the development of mobile detector system and the status quo, through the analysis of the sensor system to establish a research and development direction of then introduced the system design requirements, the detector system work environment more complex, so the system should be set up protection . On this basis, described the hardware design and system software design and practical analysis.
 This topic has higher cost-effective use of the SCM MSP430 constitute the core of the system, according to the sensor measurement signal, and moving objects on the identification and measurement, and to the outside world to respond.
