Abstract

The invention provides a fault diagnosis and processing method under a blast furnace trough, which is realized by a fault diagnosis and processing program set up on a fault response PC machine, wherein the fault diagnosis and processing program comprises an optical proximity correction (OPC) client, a background database, a fault processing program and an operation interface. An OPC client exchanges data with an OPC server to synchronize and update programmable logic controller (PLC) real-time data; the background database keeps in communication with the fault processing program and provides fault cases and processing methods thereof for the fault processing program; the fault processing program analyzes collected data so as to determine fault contents and is combined with the background database to provide a processing method; and the operation interface provides a fault list, working mode selection and a dialog box. In the invention, only one fault response PC machine is additionally arranged on the basis of the original control system of a blast furnace, and therefore, the equipment investment is small, the occupation area is small and the use effect is good.

Description

Technical field

[0001] The invention relates to a feeding system under a blast furnace tank. Background technique

[0002] The system under the blast furnace tank has the characteristics of fewer types of equipment, but a larger number and more complicated operations. The large number of equipment leads to a higher probability of failure, and different failures or different handling methods of the same failure will lead to different results, which requires the operator to maintain a high level of attention and processing throughout the process. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fault diagnosis and processing method under the blast furnace tank, which can diagnose various faults in the system under the blast furnace tank, and automatically adopt corresponding processing methods.

[0004] The technical scheme adopted by the present invention is: the fault diagnosis and processing method under the blast furnac...
