DCS系统是我们化工企业生产中比较重要的系统工具之一,那么如何正确有效的掌握系统维护方法,提高系统运行效率,保障系统良好运行?那么下面以浙大中控DCS卡件为例,为大家从基础维护方面上入手,帮助更多朋友掌握正确的系统维护方法。
DCS system is one of the more important system tools in the production of our chemical enterprises, so how to correctly and effectively master the system maintenance methods, improve the system operation efficiency and ensure the good operation of the system? Now let's take the DCS card of Zhejiang University as an example to help more friends master the correct system maintenance methods from the aspect of basic maintenance.
1、日常维护
1. Routine maintenance
(1)中控室管理
(1) Central control room management
密封所有可能引入灰尘、潮气和鼠害或其它有害昆虫的走线孔(坑)等;
Seal all wiring holes (pits) that may introduce dust, moisture, rats or other harmful insects;
保证空调设备稳定运行,保证室温变化小于+5℃/h,避免由于温度、湿度急剧变化导致在系统设备上的凝露;
Ensure the stable operation of the air conditioning equipment, ensure that the change of room temperature is less than +5 ℃ /h, and avoid condensation on the system equipment due to the rapid change of temperature and humidity;
现场与控制室合理隔离,避免现场灰尘进入控制室,同时控制室定时清扫,保持清洁。
The site shall be reasonably isolated from the control room to prevent dust from entering the control room. At the same time, the control room shall be cleaned regularly to keep it clean.
(2)操作站管理
(2) Operation station management
文明操作,爱护设备,保持清洁,防灰防水;
Operate in a civilized manner, take good care of the equipment, keep it clean, ash proof and waterproof;

2、预防维护
2. Preventive maintenance
每年至少一次
At least once a year
冗余测试
Redundancy test
卡件冗余测试 、通信冗余测试 、供电冗余
Card redundancy test, communication redundancy test, power supply redundancy
总体观察
Overall observation
3、大修期间维护
3. Maintenance during overhaul
(1)系统停电
(1) System power failure

系统停电步骤:
System power failure steps:
每个操作站依次退出实时监控及操作系统后,关操作站工控机及显示器电源;
After each operation station exits the real-time monitoring and operation system in turn, turn off the power supply of the industrial computer and display of the operation station;
逐个关控制站电源箱电源;
Turn off the power supply of the control station power box one by one;
关闭各个支路电源开关;
Turn off the power switch of each branch;
关闭不间断电源(UPS)电源开关;
Turn off the uninterruptible power supply (UPS) power switch;
关闭总电源开关。
Turn off the main power switch.
停电维修:
Outage maintenance:
操作站、控制站停电吹扫检修。包括工控机内部,控制站机笼、电源箱等部件的灰尘清理。
The operation station and control station are powered off and purged for maintenance. Including the dust cleaning of the internal part of the industrial computer, the cage of the control station, the power box and other components.
系统供电线路检修。包括分电箱、端子排、继电器、安全栅等。确保各部件工作正常、线路可靠连接。!特别注意,断电后UPS电池仍然会产生很高电压,请注意安全。
System power supply line maintenance. Including distribution box, terminal strip, relay, safety barrier, etc. Ensure that all components work normally and the circuit is reliably connected.! Pay special attention to the fact that the ups battery will still generate high voltage after power failure. Please pay attention to safety.
接地系统检修。包括端子检查、对地电阻测试。
Maintenance of grounding system. Including terminal inspection and ground resistance test.
通信线路连接线、连接点检查,确保各部件工作正常、线路可靠连接。做好双重化网络线的标记
Check the connection line and connection point of the communication line to ensure that all components work normally and the line is reliably connected. Mark the dual network cable
