Today, many elderly people or children, especially disabled or sudden illness of patients, when faced with an emergency, such as thieves burglary, fire, gas leaks, disease help. Inconvenient due to their own actions or excessive panic did not alarm information can be issued, the most basic telephone help can not guarantee the security of their home, you must create a stable, reliable, easy to operate the emergency alarm system.In order to solve the above problems, the graduation project by GSM module, gas detection sensors, smoke sensors, infrared sensor and microcontroller connection to achieve realtime monitoring of the safety of the family, issued the alarm sound when an abnormal phenomenon, through the GSM module send out a distressinformation。 GSM。一個(gè)社會(huì)的人身安全,以及信息安全得不到保障就沒(méi)有科學(xué)技術(shù)的高速發(fā)展。另一方面就是固定電話不方便攜帶。集群系統(tǒng)功耗很大,網(wǎng)絡(luò)架設(shè)和維護(hù)費(fèi)用很高,而且需要 購(gòu)買固定的頻點(diǎn),很不適用。 方案設(shè)計(jì)以及原理框圖本文介紹了基于 GSM 短信模塊的家庭智能緊急呼救系統(tǒng)工作原理,系統(tǒng)主要由 GSM模塊、煤氣檢測(cè)傳感器模塊、溫度傳感器模塊、紅外傳感器模塊以及 315M 無(wú)線模塊組成。方案一:采用 51 系列的單片機(jī)作為本設(shè)計(jì)的微控制器。PIC 單片機(jī)指令很少,寫控制指令可能相對(duì)困難。由于考慮到本設(shè)計(jì)的程序的大小,還可能用到多個(gè)中斷以及 A/D 轉(zhuǎn)換、程序響應(yīng)時(shí)間、抗干擾能力等問(wèn)題,普通的 8051 單片機(jī)滿足不了設(shè)計(jì)的需求。增強(qiáng)型 8051 CPU,1T,單時(shí)鐘/機(jī)器周期,指令代碼完全兼容傳統(tǒng)8051.工作電壓:STC12C5A60S2 系列工作電壓: 5。片上集成1280字節(jié) RAM 。可通過(guò)串口()直接下載用戶程序,數(shù)秒即可完成一片。1外部掉電檢測(cè)電路: ,誤差為177。5% 到177。0V 單片機(jī)為: 11MHz ~ 17MHz。13個(gè)時(shí)鐘輸出口,輸出時(shí)鐘,。 也可用來(lái)再實(shí)現(xiàn)2個(gè)定時(shí)器。1STC12C5A60S2系列有雙串口,后綴有S2標(biāo)志的才有雙串口,RxD2/(可通過(guò)寄存器設(shè) ),TxD2/()。STC12C5A60S2 單片機(jī)中包含中央處理器(CPU)、程序存儲(chǔ)器(Flash)、數(shù)據(jù)存儲(chǔ)器(SRAM)、定時(shí)/計(jì)數(shù)器、UART 串口、串口 I/O 接口、高速 A/D 轉(zhuǎn)換、SPI 接口、PCA、看門狗及片內(nèi) R/C 振蕩器和外部晶體振蕩電路等模塊。簡(jiǎn)單來(lái)講,GSM 模塊加
