如何快速排查中控係統通訊故障?
How to quickly check the communication failure of central control system?
在係統運行過程中若發現通訊故障,應重點做如下檢查:
In case of communication failure during system operation, the following inspection shall be focused on:
1、了解清楚具體故障現象,是所有通訊中斷還是某部分數據通 訊異常,還是某操作站通訊異常,這對之後的排查很重要。
1. It is very important to understand the specific fault phenomenon, whether all communication is interrupted or some data communication is abnormal, or whether the communication of an operation station is abnormal.
2、中控工程師權限進入監控故障診斷畫麵,觀察是否有通訊卡件或總線故障報警(如數據轉發卡,主控卡等)提示。發現卡件故障用備件更換。
2. The central control engineer has the right to enter the monitoring fault diagnosis screen and observe whether there are communication card or bus fault alarm (such as data transfer card, master control card, etc.) prompt. Replace the card with spare parts if it fails.

3、檢查目前網絡是否通暢,檢查交換機、控製站供電是否正常。可用計算機ping命令檢查各網絡節點是否通暢。
3. Check whether the current network is unobstructed, and check whether the power supply of switch and control station is normal. The ping command can be used to check whether the network nodes are smooth.
4、網線、交換機、SBUS線等故障均可能引起網絡故障,可將其排除法更換測試。
4. Network cable, switch, SBUs line and other faults may cause network failure, which can be replaced by troubleshooting test.
5、檢查有問題操作站IP設置是否正確,卡件地址(主控卡、數據轉發卡)設置是否正確、網卡驅動是否正確安裝,網線連接是否不正確(交叉等)。
5. Check whether the IP setting of the operation station in question is correct, whether the card address (Master card, data transfer card) is set correctly, whether the network card driver is installed correctly, and whether the network cable connection is incorrect (crossover, etc.).
