一、建筑塔鐘工作原理

塔鐘從外觀分為(wei)室內(nei)和室外兩(liang)部(bu)分，其中室內(nei)有(you)母(mu)(mu)(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)控(kong)制(zhi)系(xi)(xi)統。室外是子(zi)鐘(zhong)(zhong)(zhong)(zhong)部(bu)分，又(you)可(ke)分為(wei)機芯、鐘(zhong)(zhong)(zhong)(zhong)針(zhen)、刻度(du)、照明系(xi)(xi)統和報時(shi)揚(yang)聲器(qi)部(bu)分。戶外鐘(zhong)(zhong)(zhong)(zhong)表控(kong)制(zhi)器(qi)自身有(you)時(shi)鐘(zhong)(zhong)(zhong)(zhong)電路(lu)，產生信(xin)(xin)(xin)號(hao)，其精度(du)為(wei)2秒/月，同時(shi)CPU不斷(duan)接收GPS和北斗信(xin)(xin)(xin)號(hao)機來的(de)(de)時(shi)間(jian)(jian)信(xin)(xin)(xin)號(hao)，對其自身的(de)(de)時(shi)間(jian)(jian)信(xin)(xin)(xin)號(hao)校正(zheng)，從而(er)保(bao)證(zheng)其時(shi)間(jian)(jian)信(xin)(xin)(xin)號(hao)的(de)(de)度(du)。母(mu)(mu)(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)不斷(duan)的(de)(de)將時(shi)間(jian)(jian)信(xin)(xin)(xin)號(hao)發送(song)給子(zi)鐘(zhong)(zhong)(zhong)(zhong)，輸出(chu)驅動信(xin)(xin)(xin)號(hao)驅動電機工作，完(wan)成走(zou)時(shi)。子(zi)鐘(zhong)(zhong)(zhong)(zhong)將其狀態(tai)回(hui)轉給母(mu)(mu)(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)，接受母(mu)(mu)(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)的(de)(de)監(jian)控(kong)，同時(shi)子(zi)鐘(zhong)(zhong)(zhong)(zhong)走(zou)時(shi)還受反饋開(kai)關的(de)(de)監(jian)控(kong)，從而(er)保(bao)證(zheng)整(zheng)個(ge)子(zi)鐘(zhong)(zhong)(zhong)(zhong)構成一個(ge)閉環系(xi)(xi)統。而(er)母(mu)(mu)(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)與子(zi)鐘(zhong)(zhong)(zhong)(zhong)又(you)構成一個(ge)大(da)的(de)(de)閉環系(xi)(xi)統。所以(yi)保(bao)證(zheng)了整(zheng)個(ge)建(jian)筑鐘(zhong)(zhong)(zhong)(zhong)表系(xi)(xi)統的(de)(de)準確無(wu)誤。

二、學校屋頂鐘表的意義

學校(xiao)(xiao)作(zuo)為(wei)一個教書育人的(de)特殊環(huan)境，對時(shi)間有著不一樣的(de)要求。學生是祖國的(de)未(wei)來，要從小(xiao)養成守時(shi)、惜(xi)時(shi)的(de)好習慣。在現代的(de)學校(xiao)(xiao)設計規劃中，經常(chang)會有大(da)型(xing)鐘(zhong)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(xiao)安裝(zhuang)大(da)鐘，不僅(jin)可以根據需要設置報(bao)時(shi)(shi)區(qu)間(jian)和報(bao)時(shi)(shi)內容，還可以設置晚上亮(liang)的(de)效(xiao)果，方便(bian)大(da)家看到時(shi)(shi)間(jian)。因為其追蹤GPS衛星(xing)時(shi)(shi)間(jian)自動校(xiao)時(shi)(shi)，所以走時(shi)(shi)精準(zhun)。很多(duo)的(de)車站、學(xue)校(xiao)、小(xiao)區(qu)都會有這種(zhong)戶(hu)外(wai)鐘的(de)影子(zi)。
