一、建筑塔鐘工作原理

塔鐘從(cong)外觀分(fen)為(wei)室(shi)內和(he)室(shi)外兩(liang)部分(fen)，其中室(shi)內有母(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)控制系(xi)統(tong)(tong)。室(shi)外是子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)部分(fen)，又可分(fen)為(wei)機芯、鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)針、刻度(du)、照明系(xi)統(tong)(tong)和(he)報時揚聲器(qi)部分(fen)。戶外鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)表控制器(qi)自(zi)身(shen)有時鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)電路，產生信號(hao)(hao)(hao)(hao)，其精(jing)度(du)為(wei)2秒(miao)/月，同時CPU不(bu)斷接收GPS和(he)北斗信號(hao)(hao)(hao)(hao)機來的(de)(de)時間信號(hao)(hao)(hao)(hao)，對其自(zi)身(shen)的(de)(de)時間信號(hao)(hao)(hao)(hao)校正，從(cong)而保證其時間信號(hao)(hao)(hao)(hao)的(de)(de)度(du)。母(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)不(bu)斷的(de)(de)將時間信號(hao)(hao)(hao)(hao)發送給子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)，輸出(chu)驅動信號(hao)(hao)(hao)(hao)驅動電機工(gong)作，完成走時。子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)將其狀態回轉(zhuan)給母(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)，接受母(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)監控，同時子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)走時還受反饋開關的(de)(de)監控，從(cong)而保證整(zheng)個(ge)子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)構(gou)成一個(ge)閉環(huan)系(xi)統(tong)(tong)。而母(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)與子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)又構(gou)成一個(ge)大的(de)(de)閉環(huan)系(xi)統(tong)(tong)。所以保證了整(zheng)個(ge)建筑鐘(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)表系(xi)統(tong)(tong)的(de)(de)準確無誤。

二、學校屋頂鐘表的意義

學(xue)校作為一個教書育人的(de)(de)特殊環境，對時(shi)間有著不(bu)一樣的(de)(de)要求。學(xue)生是祖國的(de)(de)未(wei)來(lai)，要從小養成守時(shi)、惜時(shi)的(de)(de)好習慣(guan)。在現代的(de)(de)學(xue)校設計(ji)規劃中，經常會有大型鐘表的(de)(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。

學校安裝大(da)鐘(zhong)，不僅可(ke)以根據(ju)需要設置報時(shi)(shi)(shi)區間和(he)報時(shi)(shi)(shi)內容，還可(ke)以設置晚上亮的效果，方便大(da)家看到時(shi)(shi)(shi)間。因為其追蹤GPS衛星時(shi)(shi)(shi)間自動校時(shi)(shi)(shi)，所以走(zou)時(shi)(shi)(shi)精準。很多的車站、學校、小區都會有(you)這種(zhong)戶(hu)外鐘(zhong)的影(ying)子。
