style="font-size:12px;">由于歷史的原因,我國目前的電力行業(yè)的時(shí)間同步系統(tǒng)的時(shí)鐘源大都采用米國GPS系統(tǒng)做為主時(shí)鐘源。目前，GPS是米國軍方控制的軍民共用的系統(tǒng)，對全世界開放。我國目前使用的GPS屬于**接收的米國信號(hào)。盡管如此，但是米國人并不承諾保證你的使用。這樣就帶來一個(gè)安全問題, 如涉及**系統(tǒng)以米國的GPS作為主時(shí)鐘源，這便存在著重大的安全隱患，一旦發(fā)生ZhanZheng等緊急事態(tài)，米國關(guān)閉或調(diào)整GPS信號(hào)，將給我們的安全帶來很大影響。</span> </p> <p> （2）如何建立完善的時(shí)間同步機(jī)制,同時(shí)使各安全系統(tǒng)時(shí)間同步系統(tǒng)不受他國控制,是擺在國家面前的一大課題?北斗時(shí)鐘同步裝置就是在這種情況下應(yīng)運(yùn)而生的，為了保障我國各行業(yè)系統(tǒng)的生產(chǎn)、運(yùn)行安全，北斗雙模時(shí)鐘同步裝置同時(shí)接收GPS和北斗兩個(gè)不同衛(wèi)星系統(tǒng)的標(biāo)準(zhǔn)時(shí)間信息，當(dāng)其中一個(gè)系統(tǒng)接收故障或者信號(hào)異常時(shí)，可以自動(dòng)切換到另外一個(gè)另外一個(gè)授時(shí)系統(tǒng)，保證上游時(shí)間源的穩(wěn)定接收，由于北斗衛(wèi)星導(dǎo)航定位系統(tǒng)是由我國自主開發(fā)的，相對于GPS系統(tǒng)來說，在安全性上也更有保障。四川衛(wèi)星授時(shí)設(shè)備/裝置完全知識(shí)產(chǎn)權(quán)公司繼續(xù)優(yōu)化廣域時(shí)間同步系統(tǒng)的應(yīng)用，在產(chǎn)品國產(chǎn)化及先進(jìn)技術(shù)的引入，繼續(xù)提高廣域時(shí)間同步精度及功能。</p><div

在諸多涉及國計(jì)民生的重要領(lǐng)域，高精度、高安全性能的北斗同步時(shí)鐘可以保證整個(gè)系統(tǒng)的安全運(yùn)行，如：通信領(lǐng)域如果各基站之間時(shí)間達(dá)不到高度統(tǒng)一，就會(huì)出現(xiàn)通話中斷，掉線等故障；電網(wǎng)調(diào)度如果沒有精確地時(shí)鐘基準(zhǔn)作為參考就會(huì)影響這個(gè)系統(tǒng)的正常運(yùn)轉(zhuǎn)；安防視頻監(jiān)控網(wǎng)中的服務(wù)器錄像機(jī)如果時(shí)間不對，就無法進(jìn)行日志分析。而GPS導(dǎo)航授時(shí)系統(tǒng)的所有者是美國軍方，針對這一問題，我國自主研發(fā)的北斗衛(wèi)星導(dǎo)航授時(shí)系統(tǒng)可以保證在GPS衛(wèi)星信號(hào)中斷的情況下為本國所有需要精確授時(shí)的領(lǐng)域提供精確的時(shí)間參考。比如現(xiàn)在CDMA和大型電網(wǎng)改造都要求采用GPS/北斗雙模時(shí)間服務(wù)器就是基于以上考慮。因此，在關(guān)鍵領(lǐng)域采用雙模授時(shí)系統(tǒng)，可以保證我們對系統(tǒng)安全性能的要求。
