一、建筑塔鐘工作原理
塔鐘從外(wai)(wai)觀分(fen)為室(shi)內和(he)室(shi)外(wai)(wai)兩部分(fen),其(qi)(qi)中室(shi)內有(you)母(mu)鐘(zhong)(zhong)(zhong)控(kong)制(zhi)系統。室(shi)外(wai)(wai)是子(zi)(zi)鐘(zhong)(zhong)(zhong)部分(fen),又(you)可(ke)分(fen)為機芯、鐘(zhong)(zhong)(zhong)針、刻度、照明系統和(he)報時(shi)(shi)揚聲器部分(fen)。戶外(wai)(wai)鐘(zhong)(zhong)(zhong)表(biao)控(kong)制(zhi)器自身有(you)時(shi)(shi)鐘(zhong)(zhong)(zhong)電路,產生(sheng)信號(hao),其(qi)(qi)精度為2秒/月(yue),同(tong)時(shi)(shi)CPU不斷接(jie)(jie)收GPS和(he)北斗(dou)信號(hao)機來的時(shi)(shi)間(jian)(jian)信號(hao),對其(qi)(qi)自身的時(shi)(shi)間(jian)(jian)信號(hao)校正(zheng),從而(er)保證(zheng)其(qi)(qi)時(shi)(shi)間(jian)(jian)信號(hao)的度。母(mu)鐘(zhong)(zhong)(zhong)不斷的將時(shi)(shi)間(jian)(jian)信號(hao)發送給(gei)子(zi)(zi)鐘(zhong)(zhong)(zhong),輸出驅(qu)動信號(hao)驅(qu)動電機工作,完(wan)成走(zou)時(shi)(shi)。子(zi)(zi)鐘(zhong)(zhong)(zhong)將其(qi)(qi)狀態回轉給(gei)母(mu)鐘(zhong)(zhong)(zhong),接(jie)(jie)受母(mu)鐘(zhong)(zhong)(zhong)的監控(kong),同(tong)時(shi)(shi)子(zi)(zi)鐘(zhong)(zhong)(zhong)走(zou)時(shi)(shi)還(huan)受反饋開關的監控(kong),從而(er)保證(zheng)整個子(zi)(zi)鐘(zhong)(zhong)(zhong)構成一個閉(bi)環系統。而(er)母(mu)鐘(zhong)(zhong)(zhong)與子(zi)(zi)鐘(zhong)(zhong)(zhong)又(you)構成一個大的閉(bi)環系統。所以保證(zheng)了整個建筑鐘(zhong)(zhong)(zhong)表(biao)系統的準確無誤。
二、學校屋頂鐘表的意義
學校作為一個(ge)教書(shu)育人的(de)(de)特(te)殊環境,對時間有著不一樣的(de)(de)要(yao)(yao)求。學生是祖國(guo)的(de)(de)未來,要(yao)(yao)從小養(yang)成(cheng)守時、惜時的(de)(de)好習慣。在現(xian)代(dai)的(de)(de)學校設計(ji)規劃(hua)中,經(jing)常會(hui)有大(da)型鐘表的(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(yi)根據需要設置(zhi)(zhi)報時(shi)(shi)(shi)區間和報時(shi)(shi)(shi)內容,還(huan)可以(yi)設置(zhi)(zhi)晚(wan)上亮的效(xiao)果,方便大(da)家看到(dao)時(shi)(shi)(shi)間。因為其(qi)追蹤(zong)GPS衛星(xing)時(shi)(shi)(shi)間自動校(xiao)時(shi)(shi)(shi),所以(yi)走(zou)時(shi)(shi)(shi)精準。很多(duo)的車(che)站(zhan)、學校(xiao)、小區都會(hui)有這種(zhong)戶外鐘的影子。
