熱電阻信號不準確怎麽排查?
How to check if the signal of thermal resistance is not accurate?
A:首先,查看熱電阻的組態,確認了組態中的熱電阻型號和實際的型號保持一致;其次,保證上下位機組態一致。假如還是懷疑測溫有問題的話,能夠丈量現場熱電阻A和B之間的阻值為R1;B和C之間的阻值為R2。
A: First, check the configuration of the thermal resistance, and confirm that the thermal resistance model in the configuration is consistent with the actual model; second, ensure that the upper and lower computer configuration is consistent. If you still suspect that there is a problem with temperature measurement, the resistance between a and B can be measured as R1; the resistance between B and C is R2.
根據3線製熱電阻的測溫原理,可以得到熱電阻的實際電阻值為R1-2R2。然後查表找出對應的溫度。然後用這個溫度和監控上的溫度再進行比較。如果出入較大,請更換卡件後再次嚐試。
According to the temperature measurement principle of three wire thermistor, the actual resistance value of the thermistor is r1-2r2. Then look up the table to find out the corresponding temperature. Then compare this temperature with the temperature on the monitor. If the access is large, please replace the card and try again.
如何快速排查係統通訊故障?
How to quickly check the system communication failure?
在係統運行過程中若發現通訊故障,應重點做如下檢查:
If communication failure is found in the process of 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 it is all communication interruption or some data communication abnormality, or an operation station communication abnormality.

2、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 engineer has the right to enter the monitoring fault diagnosis screen to observe whether there is communication card or bus fault alarm (such as data transfer card, master control card, etc.). If the card fails, replace it with spare parts.
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 whether the power supply of switches and control stations is normal. The ping command can be used to check whether each network node is unobstructed.
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 faults, so the troubleshooting method can be replaced and tested.
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 control card, data transfer card) is set correctly, whether the network card driver is installed correctly, and whether the network cable connection is incorrect (cross, etc.).
