电缆、配线、端子接头接触不良;
②电源在运作过程中导致接头松动;
③螺栓连接处,因外力导致接触不良;
④绝缘层质量不过关或者电源线阻抗增大;
⑤因外物腐蚀导致接触不良PM864AK01;
⑥电源线布线方式不合理;
⑦地线布置不合理,出现干扰电源系统运作的磁信号。
? 故障处理:
电源故障是较为常见的故障类型,随着DCS 电源模块使用时间的延长,电源故障率也会逐步提升,而故障处理措施主要为:
①选用高质量电源模块,适当调整电源冗余率;
②在检修期间处理电源接线松动等问题;
③优化电源布线,解决电磁干扰问题;
④建立电源维护档案,根据其使用时间,定期更换电源。
DCS 系统网络存在多个节点,一方面是人机界面连接节点,如工程师站节点、操作员站节点;另一方面是连接中央处理器的节点。PM864AK01控制处理器,PM864AK01数据库
网络通信故障主要表现为:服务器死机、操作员站掉线或者死机、分散处理单元死机、冗余控制器控制无效、通信中断等。
? 故障分析:
除了软件设计不合理和网络堵塞外,网络通信故障主要由以下几个方面原因所导致:
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.
