摘要
 廣播音頻信號(hào)報(bào)警器由報(bào)警器和統(tǒng)計(jì)查詢兩部分組成，報(bào)警器由單片機(jī)控制，負(fù)責(zé)實(shí)時(shí)監(jiān)測(cè)立體聲，二路音頻信號(hào)，如果發(fā)現(xiàn)停播，立即記錄停播的日期和時(shí)間，信號(hào)恢復(fù)的時(shí)間等信息，并將它們存儲(chǔ)在單片機(jī)內(nèi)部的E2PROM，一旦有IC卡插入，便將儲(chǔ)存在E2PROM中的停播信息儲(chǔ)存到IC卡上，再通過(guò)IC卡將停播信息用讀卡器輸入到電腦里，或直接由電腦通過(guò)RS-485接口從報(bào)警器處讀取數(shù)據(jù)，再由管理軟件進(jìn)行分析匯總最后用報(bào)表的形式打印出來(lái)。管理軟件還可以通過(guò)數(shù)據(jù)庫(kù)處理，實(shí)現(xiàn)查詢、統(tǒng)計(jì)等功能。本文試從以下幾個(gè)方面對(duì)該報(bào)警器的設(shè)計(jì)開(kāi)發(fā)過(guò)程進(jìn)行論述：
 1、問(wèn)題的提出，簡(jiǎn)要地說(shuō)明了在怎么樣的背景下開(kāi)發(fā)該系統(tǒng)的。
 2、該報(bào)系統(tǒng)的設(shè)計(jì)思想。
 3、各部分較為詳細(xì)的流程，程序語(yǔ)句。
 4、開(kāi)發(fā)手段的簡(jiǎn)要論述。

ABSTRACT
 The broadcast tonic train signalling alarm apparatus inquires two parts by the alarm apparatus and the statistics to be composed, the alarm apparatus by the monolithic integrated circuit control, is responsible for the real-time monitor stereo sound, two groups tonic train signallings, if discovered stops broadcasts, records the date and the time immediately which stops broadcasts, information and so on time which the signal restores, and saves them in monolithic integrate d circuit interior E2PROM, once has the IC card insertion, then will store up in E2PROM stops broadcasts the information storage to embrace to IC, again will stop through the IC card broadcasts the information with to read the card input to the computer in, or directly will read the fetching by the computer through the RS-485 connection from the alarm apparatus place according to, Again by manages software to carry on the analysis to compile finally uses the report form the form to print. Manages software also to be allowed through the database handling dbh, function and so on realization inquiry, statistics. This article tries from following several aspects to carry on the elaboration to this alarm apparatus design performance history:
 1st, question proposing, briefly explained how background develops this system under.
 2nd, this newspaper system design thought.
 3rd, each part of more detailed flows, procedure statement.
 4th, development method brief elaboration.
