【正文】 expansion chip less, and the use of ultrasmall LQFP208 package, the whole system miniaturization, and the circuit is simple, reduce the development and production can achieve the highest operating frequency of 72MHz, more powerful, able to meet the embedded system mC/OSII requirements.Alarm signal acquisition and processing module of the pyroelectric infrared sensor (PIR) RE200B and infrared sensor dedicated processing chip BISS0001 infrared sensor using the pyroelectric effect, in the form of noncontact detection of infrared radiation the human body and its transformation into a voltage in actual use Fresnel lens installed in front of the sensor can be detected from up to 10m or signal change for the slow, small amplitude characteristics of infrared signals selected BISS0001 special chip, the chip integrated operational amplifiers, voltage parators, the state controller, timer delay time and blocking time timer, fully meet the IR signal processing of D, G, Sside power supply terminal, respectively, to end and the target output voltage chip output signal VO sent to the main controller for the read, the specific circuit shown in Figure 2.Figure 2 Circuit of the alarm signal acquisition and processing module Voice alarm module is mainly produced by the NXP IIS bus data format that supports the audio codec chip UDA1341TS is panies such as SONY and NXP launch of a major for the mon digital audio processing technology and equipment, a standard interface, it will separate the audio data and clock signals, thus avoiding the jitter caused by the clock, the system no longer need to remove jitter of the the IIS bus interface signal lines: bit clock input BCK, word select input WS, data entry DATAI, DATAO and audio data output signal line system clock provides the master controller to send and receive IIS bus interface signal line a total of six groups, namely IISRX_CLK, IISRX_WS, IISRX_SDA, IISTX_CLK, IISTX_WS, IISTX_SDA, the specific circuit shown in Figure 3.Figure 3 The circuit of voice alarm Short message sending module from Siemens TC35i mainly by the GSM baseband processor module, GSM RF module, power module (ASIC), flash memory, ZIF connector, the antenna structure of six facilitate debugging, we purchased a based on the GSM module TC35i development equipment, the development has been set aside for equipment and wiring connected to the main controller ports that TXD, RXD, GND, only these three connection ports, respectively, and LPC2478 the RXD, TXD, GND is connected to the main controller can be achieved by the control module, the hardware connection is very simple, you can speed up the development progress. Default information storage module is mainly constituted by the SD provides a SD/MMC card host controller, so the design of SD/MMC card interface circuit, just received these interfaces corresponding SD/MMC card connector on , namely, SD and SPI this design, we chose SPI mode, SD Card SPI channel formed by the following four signals: CS (chip select), CLK (clock), DataIn (host to card data signal) and DataOut (card to host data signal).CS is the SD card chip select signal line, in the SPI operation, must remain active low, CLK easy to sync, DataIn not only transmit data, it sends the mand, the same things, DataOut addition to sending the data transfer acknowledge card is mainly used to store information on normal speech and voice alarm, and the default alarm short controlled by the whole system is programmed using C language, all of modular design.Conclusion This article describes the average family with intelligent security alarm system, the use of NXP Semiconductors (NXP Semiconductors) highly integrated LPC2478 microprocessor chip integrated interface for voice processing IIS, SPI interface is used for SD card information to access, UART interface is used to implement the control of GSM module, the chipchiprich resources to meet the design requirements greatly simplify the external circuit.附錄B 外文翻譯.基于恩智浦LPC2478系列智能安防報(bào)警系統(tǒng)概述 出現(xiàn)在智能報(bào)警系統(tǒng)的市場(chǎng)表現(xiàn)較為單一，價(jià)格昂貴，一些系統(tǒng)往往是在門窗被摧毀時(shí)，發(fā)出警告，通知主人或報(bào)警中心，并響應(yīng)需要一些時(shí)間，以及更長(zhǎng)為更多的家庭財(cái)產(chǎn)，是危險(xiǎn)的最佳方法，安全性是當(dāng)犯罪分子侵入語(yǔ)音警告，當(dāng)試圖增加心理壓力，迫使他們離開自愿，當(dāng)這個(gè)方法失敗了，你也可以記錄的入侵時(shí)間發(fā)送基于這個(gè)思想，在門口時(shí)，人類活動(dòng)，熱釋電紅外傳感器來(lái)檢測(cè)后發(fā)送的ASIC主控制器基于ARM7 ，根據(jù)主控制器發(fā)出的信號(hào)持續(xù)時(shí)間一般提示提示說(shuō)明或警告，警告，短消息的形式將信息發(fā)送到手機(jī)頭的住戶，易于使用，不需要復(fù)雜的操作的戶主是非常適合一般家庭使用。系統(tǒng)編程：該系統(tǒng)采用C語(yǔ)言編程，所有的模塊化設(shè)計(jì)。 sbit x4=P2^3。uchar table[16]={0x3f,0x06,0x5B,0x4F,0x66, 0x6D, 0x7D,0x07,0x7F,0x6F}。 TH0=(6553615536)/256。x4=1。x4=1。x2=1。init1()。amp。kk=0。fmqchu=0。x2=0。x4=0。x2=1。j)。uchar aa=0,bb=0,cc=0,dd=0。sbit key=P1^0。 默認(rèn)信息存儲(chǔ)模塊主要由SD / MMC卡主控制器，所以支持SD / MMC卡接口電路設(shè)計(jì)上， / MMC接口這些接口對(duì)應(yīng)的SD / ，即可持續(xù)發(fā)展和SPI ，我們選擇了SPI模式，SD卡SPI通道由以下四個(gè)信號(hào)形成：CS（片選），時(shí)鐘（時(shí)鐘）， DataIn（主機(jī)到卡的數(shù)據(jù)信號(hào)）和DataOut（卡到主機(jī)的數(shù)據(jù)信號(hào)）。感謝你們四年來(lái)的關(guān)懷，謝謝！參考文獻(xiàn)[1] 樊延虎,邵思飛,[J].延安大學(xué)學(xué)報(bào)(自然科學(xué)版).2002,12(02), 2930.
