一、建筑塔鐘工作原理

塔鐘從外觀分為(wei)(wei)室(shi)內(nei)和室(shi)外兩部(bu)分，其中室(shi)內(nei)有母鐘(zhong)(zhong)(zhong)控(kong)(kong)制系統(tong)。室(shi)外是子鐘(zhong)(zhong)(zhong)部(bu)分，又(you)可分為(wei)(wei)機(ji)芯、鐘(zhong)(zhong)(zhong)針、刻度、照(zhao)明系統(tong)和報時(shi)(shi)(shi)(shi)揚聲器部(bu)分。戶外鐘(zhong)(zhong)(zhong)表控(kong)(kong)制器自身有時(shi)(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)電(dian)路，產生信(xin)(xin)(xin)號，其精度為(wei)(wei)2秒(miao)/月，同(tong)時(shi)(shi)(shi)(shi)CPU不(bu)斷接收GPS和北斗信(xin)(xin)(xin)號機(ji)來的時(shi)(shi)(shi)(shi)間信(xin)(xin)(xin)號，對其自身的時(shi)(shi)(shi)(shi)間信(xin)(xin)(xin)號校正，從而(er)保(bao)(bao)證(zheng)其時(shi)(shi)(shi)(shi)間信(xin)(xin)(xin)號的度。母鐘(zhong)(zhong)(zhong)不(bu)斷的將時(shi)(shi)(shi)(shi)間信(xin)(xin)(xin)號發(fa)送給子鐘(zhong)(zhong)(zhong)，輸出(chu)驅(qu)動(dong)信(xin)(xin)(xin)號驅(qu)動(dong)電(dian)機(ji)工作，完(wan)成走(zou)時(shi)(shi)(shi)(shi)。子鐘(zhong)(zhong)(zhong)將其狀(zhuang)態回轉給母鐘(zhong)(zhong)(zhong)，接受(shou)母鐘(zhong)(zhong)(zhong)的監(jian)控(kong)(kong)，同(tong)時(shi)(shi)(shi)(shi)子鐘(zhong)(zhong)(zhong)走(zou)時(shi)(shi)(shi)(shi)還受(shou)反(fan)饋(kui)開(kai)關的監(jian)控(kong)(kong)，從而(er)保(bao)(bao)證(zheng)整(zheng)個(ge)子鐘(zhong)(zhong)(zhong)構成一個(ge)閉環系統(tong)。而(er)母鐘(zhong)(zhong)(zhong)與子鐘(zhong)(zhong)(zhong)又(you)構成一個(ge)大的閉環系統(tong)。所以保(bao)(bao)證(zheng)了整(zheng)個(ge)建筑(zhu)鐘(zhong)(zhong)(zhong)表系統(tong)的準確無誤。

二、學校屋頂鐘表的意義

學校(xiao)作為一(yi)個教書育人(ren)的(de)特殊(shu)環(huan)境，對時(shi)間有著不一(yi)樣的(de)要(yao)求。學生是祖(zu)國(guo)的(de)未來，要(yao)從小養成守時(shi)、惜時(shi)的(de)好習慣(guan)。在(zai)現代(dai)的(de)學校(xiao)設(she)計規劃中，經常(chang)會有大(da)型(xing)鐘表的(de)考慮(lv)。

這種大型鐘表即是我們專業所說的“塔鐘”，它體型大，安裝難度高，安裝位置一般在鐘樓或塔樓的頂部。但是因為其可以方便的給人們提醒時間，加之設計美觀大方，成為建筑上不可或缺的一道靚麗風景。

學(xue)校安(an)裝大鐘(zhong)，不僅可(ke)以(yi)根據(ju)需(xu)要設置報時(shi)(shi)區間(jian)和(he)報時(shi)(shi)內容，還可(ke)以(yi)設置晚上亮的(de)效果，方便大家看(kan)到時(shi)(shi)間(jian)。因為其追蹤(zong)GPS衛星(xing)時(shi)(shi)間(jian)自(zi)動校時(shi)(shi)，所以(yi)走(zou)時(shi)(shi)精準。很多的(de)車站、學(xue)校、小(xiao)區都會有這種戶外鐘(zhong)的(de)影子。
