特定控制功能的各種工作程序和管理程序組成。此外,該系統(tǒng)還可使家庭具有多途徑報(bào)警、遠(yuǎn)程監(jiān)控等多種功能,如果不幸出現(xiàn)某種險(xiǎn)情,您和 110 可以在第一時(shí)間獲得通知以便進(jìn)一步采取行動(dòng)。 ISD4004。 through the decoder chip MT8870 DTMF signals on decode the password with the key operation to achieve the object of the control input and choice。系統(tǒng)通過設(shè)計(jì)了一個(gè)具有整流、濾波、穩(wěn)壓等一系列功能的模擬電路以及相應(yīng)的軟件程序來實(shí)現(xiàn)對(duì)電話線路中鈴流信號(hào)的檢測(cè)和模擬摘掛機(jī)。 本系統(tǒng)設(shè)計(jì)的是由用戶通過撥打家里的電話來實(shí)現(xiàn)遠(yuǎn)程控制家用電器。本系統(tǒng)是以AT89S52 為控制核心,通過振鈴檢測(cè)來實(shí)現(xiàn)模擬摘掛機(jī);通過音芯片 ISD4004 完成語音的錄制和播放,用來提示用戶進(jìn)行密碼輸入等一系列的操作;通過解碼芯片 MT8870 對(duì)DTMF 信號(hào)進(jìn)行解碼,用按鍵操作來實(shí)現(xiàn)密碼輸入及對(duì)控制對(duì)象的選擇;通過 ZigBee模塊組網(wǎng)來實(shí)現(xiàn)對(duì)具體家用電的控制。 并 通過 實(shí)際測(cè)試,最終實(shí)現(xiàn)了振鈴信號(hào)檢測(cè)及模擬摘掛機(jī)的功能。 through working ZigBee module to achieve the specific household electric control. Combined with specific software programs to achieve the remote appliance control system. Ring detection and analogue hook part is the focus of this article. By designing a system with a rectifier, filter, regulator and a series of functional analog circuits and the software program to achieve the ringing signal on the telephone line and the analog detection hook. Through the actual test, and finally realize the ringing signal detection and simulation pick hang up function. Keywords: remote control of home appliances。 ZigBee 目錄 目 錄 摘 要 .........................................................................................................................................
