一、建筑塔鐘工作原理

塔鐘從外觀(guan)分(fen)(fen)為室(shi)內和室(shi)外兩部(bu)分(fen)(fen)，其(qi)(qi)中室(shi)內有母(mu)(mu)鐘(zhong)(zhong)(zhong)控(kong)(kong)制系統。室(shi)外是子(zi)(zi)鐘(zhong)(zhong)(zhong)部(bu)分(fen)(fen)，又可分(fen)(fen)為機(ji)芯、鐘(zhong)(zhong)(zhong)針、刻度(du)(du)、照明系統和報時(shi)揚聲器部(bu)分(fen)(fen)。戶外鐘(zhong)(zhong)(zhong)表控(kong)(kong)制器自身(shen)有時(shi)鐘(zhong)(zhong)(zhong)電(dian)路，產生信號(hao)，其(qi)(qi)精(jing)度(du)(du)為2秒/月(yue)，同(tong)(tong)時(shi)CPU不(bu)斷(duan)接(jie)收GPS和北斗信號(hao)機(ji)來的(de)時(shi)間信號(hao)，對其(qi)(qi)自身(shen)的(de)時(shi)間信號(hao)校(xiao)正(zheng)，從而(er)保證(zheng)其(qi)(qi)時(shi)間信號(hao)的(de)度(du)(du)。母(mu)(mu)鐘(zhong)(zhong)(zhong)不(bu)斷(duan)的(de)將(jiang)時(shi)間信號(hao)發送(song)給子(zi)(zi)鐘(zhong)(zhong)(zhong)，輸(shu)出驅動信號(hao)驅動電(dian)機(ji)工作，完(wan)成(cheng)走時(shi)。子(zi)(zi)鐘(zhong)(zhong)(zhong)將(jiang)其(qi)(qi)狀態回轉給母(mu)(mu)鐘(zhong)(zhong)(zhong)，接(jie)受母(mu)(mu)鐘(zhong)(zhong)(zhong)的(de)監控(kong)(kong)，同(tong)(tong)時(shi)子(zi)(zi)鐘(zhong)(zhong)(zhong)走時(shi)還受反饋開關的(de)監控(kong)(kong)，從而(er)保證(zheng)整個(ge)子(zi)(zi)鐘(zhong)(zhong)(zhong)構(gou)(gou)成(cheng)一個(ge)閉(bi)環(huan)系統。而(er)母(mu)(mu)鐘(zhong)(zhong)(zhong)與子(zi)(zi)鐘(zhong)(zhong)(zhong)又構(gou)(gou)成(cheng)一個(ge)大的(de)閉(bi)環(huan)系統。所以(yi)保證(zheng)了整個(ge)建(jian)筑(zhu)鐘(zhong)(zhong)(zhong)表系統的(de)準確無誤。

二、學校屋頂鐘表的意義

學(xue)(xue)校作為一個教書育人的特殊環境(jing)，對時間有著不(bu)一樣的要(yao)(yao)求。學(xue)(xue)生(sheng)是祖(zu)國的未來，要(yao)(yao)從小養成守時、惜時的好習慣。在(zai)現代的學(xue)(xue)校設(she)計規(gui)劃中，經常(chang)會有大(da)型鐘表的考慮。

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。

學校安裝大鐘(zhong)，不僅可以根(gen)據需要設置報時(shi)(shi)區間和報時(shi)(shi)內容，還可以設置晚(wan)上亮的效果，方便大家看到時(shi)(shi)間。因為其追蹤(zong)GPS衛星時(shi)(shi)間自動校時(shi)(shi)，所(suo)以走時(shi)(shi)精準。很多的車站、學校、小區都會有這(zhe)種戶外鐘(zhong)的影子。
