Furnace top information collecting system of blast furnace based on field bus and information collecting method thereof

Abstract

The invention discloses a furnace top information collecting system of a blast furnace based on a field bus and an information collecting method of the furnace top information collecting system of the blast furnace, which belong to the field of automatic control in iron-making. The information collecting system provided by the invention comprises an upper computer, a data collecting unit, a processing unit and an executing unit. The upper computer, the data collecting unit, the processing unit and the executing unit are connected orderly. The data collecting unit connects the information collecting points at the furnace top of the blast furnace through the field bus and transmits the collected information to the processing unit finally. The information collecting points at the furnace top of the blast furnace comprise a material distributing device, a stock rod and a valve system. The system and method of the invention simplify the structural mode of current information collection. With a field bus connecting a plurality of devices, connecting cables and costs for installation and maintenance are saved. Meanwhile, the system avoids signal blockage caused by gathering of hundreds of detection signals of detection points and control points at the inlet of the control system, thereby increasing the reliability of the system.

Description

technical field [0001] The invention belongs to the field of ironmaking automation control, and more specifically relates to a blast furnace top data collection system and an information collection method of the blast furnace top foundation automation level. Background technique [0002] The blast furnace roof system is an important part of the blast furnace smelting system. The working state of the furnace roof system directly affects the stability of the blast furnace condition and affects the blast furnace production indicators. The way of distributing materials in blast furnace, the state of deficient and suspended materials in the furnace all depend on the accuracy of signal detection of furnace top equipment. [0003] In the blast furnace top automation system, the production conditions are particularly complicated, and the equipment is scattered in multiple points and surfaces, resulting in the disadvantages of high failure rate and large maintenance of the electrical...
