Blast furnace profile monitoring system

The invention discloses a blast furnace profile monitoring system which mainly comprises a PLC (Programmable Logic Control) system, a DSC (Dynamic Stability Control) system, an OPC (OLE for Process and Control) server, an SQL (Structured Query Language) database technology, a serial port isolation technology, an asynchronous communication technology and a WEB display technology. The blast furnace profile monitoring system is characterized in that a blast furnace data collection system and treatment system, a blast furnace copper cooling wall temperature slag and skin thickness calculation system and a blast furnace type fluctuation prewarning system are respectively established on such a basis, and all subsystems are organically combined through OPC serial port communication, an SQL database and a high-speed Ethernet. The invention can efficiently monitor the slag skin thickness of a heat surface of the copper cooling wall in a blast furnace high heat loading region i.e. a blast furnace profile, form a high-speed blast furnace type and condition information channel with strong calculation capability between the blast furnace and a main control chamber, guide blast furnace operation under the abnormal furnace conditions of slag skin thickening or thinning in the blast furnace high heat loading region and the like and ensure stable and smooth blast furnace condition as well as long service life of the blast furnace.
