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...

Abstract

The invention provides a method for diagnosing and processing faults below a blast furnace groove. The method is realized by a fault diagnosis and processing program installed on a fault response PC. The fault diagnosis and processing program comprises an OPC (OLE for Process Control) client, a background database, a fault processing program and an operating interface, wherein the OPC client and an OPC server interact data for synchronizing and updating PLC (Programmable Logic Controller) real-time data; the background database is communicated with the fault processing program and provides a fault case and a processing method therefor; the fault processing program analyzes the collected data to determine the fault content and provides the processing method in combination with the background database; and the operating interface provides a fault list, a working mode selection and a dialog box. In the invention, only one fault response PC machine is necessarily added based on the original control system of the blast furnace, the invention has less equipment investment and favorable use effect and small occupation space.

Description

technical field [0001] The invention relates to a feeding system under a blast furnace tank. Background technique [0002] The blast furnace under-trough system has the characteristics of less types of equipment, but more quantity and more complicated operation. A large number of equipment leads to a higher probability of failure, and different failures or different handling methods for the same failure will lead to different results, which requires the operator to maintain a high level of attention and processing throughout the process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fault diagnosis and treatment method under the blast furnace tank, which can diagnose various faults in the blast furnace tank system and automatically adopt corresponding processing methods. [0004] The technical scheme adopted in the present invention is: the fault diagnosis and processing method under the blast furnace tank i...
