Steel raw material blending expert system and mixing facility automatic operation control system

摘要

The blending expert system for automatically and quickly determining the optimum blending pattern for mixing and mixing the steel raw materials with the raw material yard and the automatic operation control system of the blending facility using the same are provided with the programmable controller 36 and the site. Collected through the facility sensors, and file file combination instruction information and brand-specific properties from the business computer 37 to infer to the formulation expert system (39), the expert system in the form of constraint constraint function in the expert system knowledge The system automatically operates according to the equipment operation status information for each device by calculating the set values based on the steel raw material compounding expert system and the mixing pattern determined by the compounding expert system. Program to control and control homogenization load control and mix The computer 38 and the VD U 40, which displays the blending pattern and operation status monitoring and operation performance data of various devices on a CRT screen, are connected to a computer network and constitute a higher system. The programmable controller 36 receives the operation status signals (4 to 20 mA) from the sensors and transmits them to the processor computer 38, and receives the operation command signals from the processor computer to start and stop processing for each unit, and the hopper 6 Quantitative cutoff control panel which detects the cutoff weight of the cut-off brand and compares the cut-off amount which is automatically calculated and transmitted by the processor computer 38 with the current cut-off amount, and performs quantitative cut-off control through the PID control panel 16 (11) and the belt conveyor control panel 17 and the stack 9 which drive and stop the control of the vent conveyor 8 according to the operation command signal of the processor computer 38, A rotary encoder position detector 29 for continuously tracking a position, and a stack driving motor 23 according to a position signal input from a synchro transmitter 30 for converting the RPM signal detected by the detector into a digital (4-20 mA). A programmable controller 33 for processing the start stop of the controller, an operation status signal such as a stack driving position signal and a start stop, and an operation command signal of the processor computer 38, and a center of the stack operation control panel 20 of the stack cab. Automatic operation of steel raw material mixing equipment including induction wireless cable 34 for wireless transmission between programmable controllers 36 of the cab, wireless antenna 31 and signal converters 32 and 35 for converting wireless-digital signals. It consists of a control system.
