Embodiment Construction
[0011] The fault diagnosis and processing system under the blast furnace tank adopts the OPC (OLE for Process Control) method to communicate with the PLC (programmable logic controller), and manages the fault cases and processing methods through the background database, and the case library is open. needs to be expanded. At the same time, according to the different requirements of operators, the system can provide a variety of processing methods, including fully automatic fault response.
[0012] like figure 1 As shown, the fault diagnosis and processing system under the blast furnace tank includes PLC 1, operation station 2, main switch 3, subsystem switch 4 and OPC server 5, and it also includes fault response PC 6. The connection relationship between them is: the main switch 3 and the subsystem switch 4 form the ring network of the blast furnace, the OPC server 5, the PLC 1 of each system and the operation station 2 are ring network sites, and the fault response PC 6 commu...
