如何快速排查中控系统通讯故障?
How to quickly check the communication failure of central control system?
在系统运行过程中若发现通讯故障,应重点做如下检查:
In case of communication failure during system operation, the following inspection shall be focused on:
1、了解清楚具体故障现象,是所有通讯中断还是某部分数据通 讯异常,还是某操作站通讯异常,这对之后的排查很重要。
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、中控工程师权限进入监控故障诊断画面,观察是否有通讯卡件或总线故障报警(如数据转发卡,主控卡等)提示。发现卡件故障用备件更换。
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、检查目前网络是否通畅,检查交换机、控制站供电是否正常。可用计算机ping命令检查各网络节点是否通畅。
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、网线、交换机、SBUS线等故障均可能引起网络故障,可将其排除法更换测试。
4. Network cable, switch, SBUs line and other faults may cause network failure, which can be replaced by troubleshooting test.
5、检查有问题操作站IP设置是否正确,卡件地址(主控卡、数据转发卡)设置是否正确、网卡驱动是否正确安装,网线连接是否不正确(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.).
