The application function levels of automatic control system are determined, and the basic requirements of hardware and software for each application function level are put forward
Field inspection, drive level and basic automation level are necessary when the application function level is divided. As for the process monitoring level and information management level, it should be decided according to the funding situation of the project and the user’s production management level.
3.1.4 Put forward the reasonable control scope and main control and management functions of the automatic control system
In general, the main process system of blast furnace production should be included in the control range. The distributed control system applied in the automatic control of blast furnace is generally divided into two categories according to the different emphasis on the electrical logic sequence control function and the continuous adjustment control function of the instrument: One is the electrical logic sequence control function and the instrument continuous adjustment control function are controlled by the same type of controller full DCS control system, such as the United States Westinghouse (Westinghouse) OVATION control system, Germany Siemens PCS7 control system; The other is the “PLC + DCS” control system with the electrical logic sequence control function and the instrument continuous adjustment control function respectively controlled by different types of controllers. For example, the Total Plant control system composed of HPM, an instrument continuous regulation controller from Honeywell, and an electrical logic sequence control PLC from GE, is composed of FCS, an instrument continuous regulation controller from Yokogawa, Japan, and CP23500H, an electrical logic sequence controller from Yaskawa, Japan Jointly composed control system, etc.
3.1.6 Put forward suggestions on equipment delivery at home and abroad.
3.1.7 Estimation of automatic control system investment.
3.2 Phase of comprehensive evaluation of distributed control system
Mainly from the following aspects of several systems approved by the user to conduct comprehensive evaluation and comparison, select in the technical performance, performance, reliability and other aspects are more excellent control system.
(1) Evaluate the technical performance of the control station unit of the control system. Including field data acquisition capabilities and signal isolation measures; Input and output signal processing accuracy; Memory capacity and data power-off retention time; Whether the module can be plugged and unplugged and fault tolerance; How the application software is configured.
(2) Evaluate the technical performance of the operation station unit of the control system. Including memory capacity and CRT resolution; Reliability of real-time multitask operating system; Has a variety of application support software (such as graphical configuration software, database management software, report generation software, historical trend software, fault alarm software, and system maintenance software, etc.); Configuration of graphics software
