  DCS断电前需要进行哪些检查?
  What checks should be carried out before the DCS is powered off?
  1、打开控制站柜门,观察卡件是否工作正常,有无故障显示;
  1. Open the cabinet door of control station and observe whether the card works normally and whether there is fault display;
  2、从每个操作站实时监控的故障诊断中观察是否存在故障,并进行记录;
  2. Observe whether there is a fault from the real-time monitoring fault diagnosis of each operation station, and record it;
  3、检查电源箱是否工作正常,电源风扇是否工作,5V、24V指示灯是否正常,测量记录各电压值;
  3. Check whether the power box works normally, whether the power fan works, whether the 5V and 24V indicator lights are normal, and measure and record the voltage values;
  4、备份组态、PID参数、驱动以及其他需要的重要数据;
  4. Backup configuration, PID parameters, drive and other important data needed;
  5、检查供电冗余,供电冗余包括交流供电冗余和直流供电冗余。交流供电冗余:通过分别断开冗余交流~220VAC进线的一路,系统有一半的交流供电回路失电,但系统应仍然可以正常工作。直流供电冗余测试方法如下:
  5. Check the power supply redundancy, including AC power supply redundancy and DC power supply redundancy. AC power supply redundancy: by disconnecting one circuit of redundant AC ~ 220 VAC incoming lines, half of the AC power supply circuits of the system lose power, but the system should still be able to work normally. DC power supply redundancy test method is as follows:

  (1)先断一路电源箱电源,测量每一机笼机笼母板电源端子上5V、24V的电压;
  (1) First, cut off the power supply of one circuit power box, and measure the voltage of 5V and 24V on the power terminal of each cage cage motherboard;
  (2)先通上一路电源箱电源,再断另外一路电源箱电源,再测量每一机笼母板电源端子上5V、24V的电压。电源箱5V输出电压应在5.10V~5.25V之间,电源箱24V输出电压应在23.00V~25.00V之间。如果电压偏差较大需要及时检查处理,否则会影响卡件的正常工作。
  (2) First connect the power supply of one power box, then cut off the power supply of another power box, and then measure the voltage of 5V and 24V on the power terminal of each cage motherboard. The 5V output voltage of the power box should be between 5.10v and 5.25V, and the output voltage of the 24V power box should be between 23.00v and 25.00v. If the voltage deviation is large, it is necessary to check and deal with it in time, otherwise the normal operation of the card will be affected.
  6、网线及布置检查,检查网络线缆通断情况,确认连接处是否接触良好,并及时更换故障线缆;
  6. Check the network cable and layout, check whether the network cable is in good contact, and replace the fault cable in time;
  7、UPS测试:通过断开UPS交流进线,测试UPS电池供电能力。UPS电池应定期放电,一般建议每月一次,放电方法:断开UPS交流供电采用电池供电,至电池即将释放完为止。
  7. UPS test: test the power supply capacity of UPS battery by disconnecting the AC incoming line of ups. UPS battery should be discharged regularly, generally once a month. Discharge method: disconnect UPS AC power supply and use battery power supply until the battery is about to be released.
