Data Acquisition And Data Preprocessing For The Blast Furnace Lining Monitoring System

Monitoring of lining of blast furnace is the key part in the modernized iron and steelindustry, which make the valuable meaning for manufacturing production. With thedevelopment and advancement of technology, blast furnace production needs more accurateerosion detection on of the blast furnace. It is inevitable in the future that taking real-time onlinemonitoring mode on the hearth and bottom erosion detection of the blast furnace.Through the real-time online monitoring mode can accurately observe the hearth andbottom erosion condition, provide reliable operation basis for works, and provide judgment basisfor prolonging the life of blast furnace. This article completes the data acquisition, datacommunication, data preprocessing and data store of this project.When design the system architecture, the author selects the IPC of the old blast furnacemonitoring system as this system’s data source. It means that obtaining the real-time monitoringdata of the thermodynamics through serial ports of the two PCs, and it needs one’s owncommunication protocol. Taking this method, not only don’t increase the cost of the project,influence the running of the old system, but also obtain the data this system needing.Due to the influence of noise and other issues, the obtained real-time data of this systemmaybe not accurate and even worse may lost some data. This article establishes a set ofreasonable methods to correct and fill data using interpolation algorithm and according to theinternal connection between the data of blast furnace. The result is desirable.
