style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)中UPS電源：UPS是伴隨計(jì)算機(jī)的誕生而出現(xiàn)后備電源。在安防監(jiān)控系統(tǒng)中越來越多應(yīng)用計(jì)算機(jī)技術(shù)，因此對(duì)電力供電質(zhì)量提出越來越高的要求。UPS不但可較全改善供電質(zhì)量，對(duì)整個(gè)系統(tǒng)乃至網(wǎng)絡(luò)數(shù)據(jù)較全保護(hù)，還可保證市電斷電和被人為破壞的特殊情況下，繼續(xù)正常工作運(yùn)轉(zhuǎn)。由于安防監(jiān)控系統(tǒng)對(duì)供電要求較高，所以一般會(huì)選擇在線式(正弦波，市電要求)UPS電源。給安防監(jiān)控系統(tǒng)配備UPS電源時(shí)，首先應(yīng)估算整個(gè)系統(tǒng)設(shè)備的用電功率，安全系數(shù)一般取1.2-1.5為宜，為供電系統(tǒng)留有充分的冗余量。其次根據(jù)系統(tǒng)要求延時(shí)供電時(shí)間，計(jì)算配置電池組。較后，還應(yīng)注意使用環(huán)境，防潮通風(fēng)，注重降溫，延長平均無故障工作時(shí)間，提高系統(tǒng)的可靠性。UPS電源應(yīng)設(shè)置在監(jiān)控室，實(shí)行統(tǒng)一管理。當(dāng)市電不正常時(shí)能及時(shí)為系統(tǒng)設(shè)備提供不間斷電力供應(yīng)，確保系統(tǒng)工作正常。</p><p style="text-indent:25px">監(jiān)控?cái)z像機(jī)電源的選擇還需要注意什么問題：：開始：在集中供電方案中給攝像機(jī)接電源時(shí)，不要把距離較遠(yuǎn)的攝像機(jī)和距離較近的監(jiān)控?cái)z像機(jī)接在同一臺(tái)電源上。如果接在同一臺(tái)電源上，電源電壓高了，會(huì)燒毀近距離的攝像機(jī)，電源電壓低了，距離較遠(yuǎn)的攝像機(jī)無圖像。立方體攝相機(jī)采用寬電源設(shè)計(jì)，可以在直流輸入電壓12V—36V范圍內(nèi)長期穩(wěn)定工作，徹底根除輸入電壓不穩(wěn)定(如浪涌等)對(duì)攝像機(jī)造成的危害.可以很好地解決這個(gè)問題。是對(duì)攝像機(jī)集中供電的較佳解決方案。第二：如果監(jiān)控距離太遠(yuǎn)，需要配置更高電壓的電源，如30V，36V等等，甚至直接供220V交流電，到前端再變壓。使用一段時(shí)間后，出現(xiàn)供電不足的故障現(xiàn)象。</p><div

style="text-indent:25px">UPS作為備用電源的一種，由蓄電池、逆變器、充電器、穩(wěn)壓穩(wěn)頻器、轉(zhuǎn)換開關(guān)組成。當(dāng)市電正常輸入時(shí)，UPS就將市電穩(wěn)壓后供給負(fù)載使用，同時(shí)對(duì)內(nèi)置電池組充電，把能量儲(chǔ)存在電池中;當(dāng)市電中斷(事故停電)或輸入故障時(shí)，UPS立即將內(nèi)置電池的能量轉(zhuǎn)換，瞬間以220伏交流電繼續(xù)供負(fù)載使用，使負(fù)載維持正常工作并保護(hù)負(fù)載軟硬件不受損壞。UPS電源在安防監(jiān)控系統(tǒng)中，不但可以較全改善供電質(zhì)量，對(duì)整個(gè)系統(tǒng)乃至網(wǎng)絡(luò)數(shù)據(jù)較全保護(hù)，還可保證市電斷電和被人為破壞的特殊情況下，繼續(xù)工作。一定要看清選購的安防監(jiān)控電源的電路設(shè)計(jì)。濟(jì)南安防集中供電電源批發(fā)哪家好</p><p
