A decarburization furnace information system and its control method based on field bus components

Abstract

The invention discloses a decarburization furnace information system based on field bus elements and a control method of the decarburization furnace information system, and belongs to the field of automatic control over steelmaking in the iron and steel industry. The decarburization furnace information system comprises a man-machine interface unit, a data processing unit, a communication unit, a detecting element and a control element, wherein the detecting element and the control element are located in the field; the a man-machine interface unit, the data processing unit and the communication unit are connected in sequence; the communication unit is connected to the detecting element and the control element in the field through a field bus via a T-type connector to transmit detection data from the detecting element to the data processing unit and transmit control data calculated through the data processing unit to the control element. According to the decarburization furnace information system based on the field bus elements and the control method of the decarburization furnace information system, by the adoption of the field bus mode, the information collection and control structure mode of an existing system is simplified, signal transmission errors are reduced from the source, and reliability of a data collection and control system is improved.

Description

technical field [0001] The invention relates to the field of automatic control of steelmaking in the iron and steel industry, and more specifically relates to a decarburization furnace information system based on field bus components and a control method thereof. Background technique [0002] The decarburization furnace is a key process of steelmaking production in the steel industry, and the quality of its products has a great impact on subsequent steel rolling production. The rapid and precise regulation of the decarburization furnace control system is an important factor in steelmaking production, which directly affects the output and quality of molten steel. [0003] In the production process of the decarburization furnace, there are many flammable and explosive gases, large metal dust, serious electromagnetic interference, and a relatively complicated production environment. At present, the detection and control components of the basic automation level of the decarburi...

Problems solved by technology

However, this document only adopts the method of moving the centralized data acquisition device forward to the site, and the transmission of signal source data still adopts conventional point-to-point analog signal transmission, which does not fundamentally solve the impact of signal transmission errors and anti-electromagnetic interference on the blast furnace control system performance problem
