電纜、配線、端子接頭接觸不良；
②電源在運(yùn)作過程中導(dǎo)致接頭松動(dòng)；
③螺栓連接處，因外力導(dǎo)致接觸不良；
④絕緣層質(zhì)量不過關(guān)或者電源線阻抗增大；
⑤因外物腐蝕導(dǎo)致接觸不良PM864AK01；
⑥電源線布線方式不合理；
⑦地線布置不合理，出現(xiàn)干擾電源系統(tǒng)運(yùn)作的磁信號(hào)。
? 故障處理：
電源故障是較為常見的故障類型，隨著DCS 電源模塊使用時(shí)間的延長，電源故障率也會(huì)逐步提升，而故障處理措施主要為：
①選用高質(zhì)量電源模塊，適當(dāng)調(diào)整電源冗余率；
②在檢修期間處理電源接線松動(dòng)等問題；
③優(yōu)化電源布線，解決電磁干擾問題；
④建立電源維護(hù)檔案，根據(jù)其使用時(shí)間，定期更換電源。
DCS 系統(tǒng)網(wǎng)絡(luò)存在多個(gè)節(jié)點(diǎn)，一方面是人機(jī)界面連接節(jié)點(diǎn)，如工程師站節(jié)點(diǎn)、操作員站節(jié)點(diǎn)；另一方面是連接中央處理器的節(jié)點(diǎn)。PM864AK01控制處理器,PM864AK01數(shù)據(jù)庫
網(wǎng)絡(luò)通信故障主要表現(xiàn)為：服務(wù)器死機(jī)、操作員站掉線或者死機(jī)、分散處理單元死機(jī)、冗余控制器控制無效、通信中斷等。
? 故障分析：
除了軟件設(shè)計(jì)不合理和網(wǎng)絡(luò)堵塞外，網(wǎng)絡(luò)通信故障主要由以下幾個(gè)方面原因所導(dǎo)致：
such as commissioning, fire control, security and water leakage detection. The reliability of computer room system is directly related to the normal, lasting and stable operation of network, server and other equipment.
3、 Haitongda solution: the system combines power distribution, power monitoring, itemized measurement of energy consumption and environmental monitoring, and proposes to build a digital and networked computer room monitoring system project based on TCP / IP transmission technology. 1. Htd-5000 series modules collect the greenhouse temperature in IDC room. 2. Htd-6000 series wireless acquisition and transmission module detects and alarms indoor water leakage, collects data on the power of each circuit in the power distribution room in the machine room, and also uploads parameters such as UPS, precision air conditioner, diesel unit, chiller, transformer and fire monitoring to the central monitoring center.
