摘     要
隨著電話的普及，越來越多的人希望能用電話實(shí)現(xiàn)遠(yuǎn)程報(bào)警。另外，很多商店下班后無人值守，當(dāng)有盜警、火警發(fā)生時(shí)，人們希望商店能自動(dòng)報(bào)警，同時(shí)能用電話進(jìn)一步查詢、核實(shí)警情等住處。我采用MCS-51單片機(jī)，配合新型的DTMF解碼芯片和語音電路，成功實(shí)現(xiàn)了用電話進(jìn)行遠(yuǎn)程報(bào)警。
我利用電話網(wǎng)傳輸數(shù)字和語音信息，可實(shí)現(xiàn)遠(yuǎn)程電話查詢，系統(tǒng)擴(kuò)展性強(qiáng)，設(shè)計(jì)新穎，功能齊全，可靠性高，操作方便。這種報(bào)警器具有很強(qiáng)的實(shí)用價(jià)值，可廣泛應(yīng)用于商店、機(jī)要部門、倉庫及居家環(huán)境實(shí)現(xiàn)安全防范。

Abstract
Along with the universality of the telephone, more and more person's hopes can realizes with the telephone the long range reports to the police.Moreover, a lot of stores go off work the behind unmanned value guards, being to have the thief , fire alarm occurrence, people hope that the store can report to the police automatically, can use the telephone at the same time further search, solid  in feeling etc. abode.I adopt the MCS-51 the single a machine, matching with new DTMF solution code  slice with speech electric circuit, the success realizes to use the telephone proceeds the long range reports to the police.
I make use of the telephone net deliver the arithmetic figure with the speech information, can realize the long range telephone search, the system expands the sex strong, design novel, the function is well-found, the dependable is high, operation convenience.This kind of report to the police tool contain very strong and practical value, extensive apply to realizes in store, confidential section, warehouse and daily life at home environments the safety against.
Key Words: The telephone reports to the police the machine,DTMF
