一、建筑塔鐘工作原理

塔鐘從(cong)外(wai)觀分(fen)(fen)為室(shi)內(nei)和室(shi)外(wai)兩(liang)部分(fen)(fen)，其中室(shi)內(nei)有母(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)控(kong)制(zhi)系(xi)(xi)統。室(shi)外(wai)是子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)部分(fen)(fen)，又(you)可分(fen)(fen)為機芯、鐘(zhong)(zhong)(zhong)(zhong)(zhong)針、刻(ke)度(du)、照(zhao)明系(xi)(xi)統和報時(shi)(shi)(shi)揚聲(sheng)器部分(fen)(fen)。戶外(wai)鐘(zhong)(zhong)(zhong)(zhong)(zhong)表(biao)控(kong)制(zhi)器自身有時(shi)(shi)(shi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)電(dian)路，產生(sheng)信(xin)(xin)號(hao)(hao)(hao)，其精度(du)為2秒/月，同(tong)時(shi)(shi)(shi)CPU不斷接(jie)收(shou)GPS和北斗信(xin)(xin)號(hao)(hao)(hao)機來的(de)(de)時(shi)(shi)(shi)間(jian)(jian)信(xin)(xin)號(hao)(hao)(hao)，對其自身的(de)(de)時(shi)(shi)(shi)間(jian)(jian)信(xin)(xin)號(hao)(hao)(hao)校正，從(cong)而保證(zheng)其時(shi)(shi)(shi)間(jian)(jian)信(xin)(xin)號(hao)(hao)(hao)的(de)(de)度(du)。母(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)不斷的(de)(de)將時(shi)(shi)(shi)間(jian)(jian)信(xin)(xin)號(hao)(hao)(hao)發送給子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)，輸出驅動(dong)信(xin)(xin)號(hao)(hao)(hao)驅動(dong)電(dian)機工作，完成(cheng)走時(shi)(shi)(shi)。子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)將其狀態回轉給母(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)，接(jie)受(shou)母(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)監控(kong)，同(tong)時(shi)(shi)(shi)子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)走時(shi)(shi)(shi)還(huan)受(shou)反饋開關的(de)(de)監控(kong)，從(cong)而保證(zheng)整個子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)構(gou)成(cheng)一個閉(bi)環系(xi)(xi)統。而母(mu)(mu)鐘(zhong)(zhong)(zhong)(zhong)(zhong)與子(zi)鐘(zhong)(zhong)(zhong)(zhong)(zhong)又(you)構(gou)成(cheng)一個大的(de)(de)閉(bi)環系(xi)(xi)統。所以(yi)保證(zheng)了整個建筑鐘(zhong)(zhong)(zhong)(zhong)(zhong)表(biao)系(xi)(xi)統的(de)(de)準確無(wu)誤。

二、學校屋頂鐘表的意義

學校作為(wei)一(yi)個教(jiao)書(shu)育人的(de)(de)特殊環(huan)境，對時間有(you)(you)著不一(yi)樣的(de)(de)要求。學生(sheng)是(shi)祖國的(de)(de)未(wei)來，要從小(xiao)養成(cheng)守時、惜(xi)時的(de)(de)好習(xi)慣。在(zai)現代(dai)的(de)(de)學校設計規劃中，經常(chang)會有(you)(you)大(da)型(xing)鐘表的(de)(de)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(xiao)安裝大(da)鐘，不僅可以根據需(xu)要設置報時區間(jian)和報時內(nei)容(rong)，還可以設置晚上亮的效果，方便大(da)家看到時間(jian)。因(yin)為(wei)其追蹤GPS衛星時間(jian)自動校(xiao)時，所(suo)以走時精準。很(hen)多(duo)的車站(zhan)、學校(xiao)、小區都會有這(zhe)種戶外(wai)鐘的影(ying)子。
