Abstract
A system for integral estimation of indexes according to detected data for blast furnace is characterized by that data communication mode is used to transmit the data acquired in-situ by blast furnace procedure control computer to data processing system composed of a server and two microcomputers over network and the data is analyzed and estimated based on example library and conventional knowledge base. In particular, the data terms such as central and edge gas indexes are added and instantaneous and stage estimation modes are uses. Its advantages include less investment in equipment and high accuracy up to over 85%.
Description
The present invention relates to a kind of system that carries out the judgement of blast furnace index according to blast furnace detection data.
Blast furnace operating will comprehensively be judged by being installed in the measuring instrument that reaches outside the stove in the stove, the regular job management, stable furnace conditions etc. will rely on operator's experience and knowledge, deposit operator's the experience and knowledge and the historical situation of blast furnace itself in computer, utilize computer that the data of blast furnace field real-time acquisition are carried out processing treatment and done analysis ratiocination, provide a comprehensive judgement at last, in time remind the operator to note, avoid artificial carelessness and flase operation, Here it is computer blast furnace comprhensive deterministic system, it is for instructing blast furnace operating, the accumulation operating experience, unified operational standard and stable furnace condition make blast furnace reach high yield, high-quality, low consumption, longevity avoids aspects such as great work accident all to have great importance.Before this, the AGOS system of existing Japanese Nippon Steel comes into operation, this system hardware partly adopts a computer workstation, facility investment and management maintenance expense are very big, and the software section decision logic is simple, and system has only selected seven project Treatment Analysis in the blast furnace detection data for use, there is not trend dynamically to judge, the judgement cycle be one hour once, comprehensive judged result and actual state comparison, coincidence rate is lower.
Purpose of the present invention is intended to make improvements at above-mentioned problems of the prior art, to obtain the high blast furnace comprhensive deterministic system of few, the comprehensive judged result coincidence rate of a kind of facility investment, to instruct blast furnace operating better, improves blast furnace production efficiency.
For realizing purpose, the relevant blast furnace permeability that the present invention collects the blast furnace process machine, stove heat, stock gas situation and distribution furnace charge decline index, furnace body temperature, the raw data of the throat armour temperature and the scoriform condition of tapping a blast furnace sends data handling system to, this system is coupled together by network by a station server and two microcomputers, raw data at first enters a data processing microcomputer, system is comprehensively judged by the blast furnace diagnostor, this programming system comprises a temporal diagnosis subsystem, a stage diagnostic subsystem, and real time data accumulation and conversational operation subsystem, at first the example that search matches in the case library of system promptly carries out the judgement based on working of a furnace example, restart conventional knowledge base after the search failure and carry out reasoning and judging, the result sends server stores to, and the service microcomputer of exporting judged result that is used for showing that another is connected with server can take out result and output demonstration from server at any time, and the dialogue service with operator is provided.
Figure 1 shows that data handling system synoptic diagram of the present invention.
Figure 2 shows that deterministic process synoptic diagram of the present invention.
Figure 3 shows that diagnostor system schematic of the present invention.
Below in conjunction with Figure of description and embodiment the present invention is done further more detailed description: as shown in Figure 1, the present invention adopts data communication method that the data of blast furnace process machine to the blast furnace field real-time acquisition are sent to by a station server and two data handling systems that microcomputer couples together by network.Raw data at first enters a data processing microcomputer that is used for data sink, computing, analysis and judgement, and result is sent server stores.Another is used for display data and judged result, provides the service microcomputer of man-machine interface dialogue service to take out data output demonstration and to carry out man-machine dialogue from server at any time.The management project that the data of collection of the present invention are promptly selected for use has 18, is divided into 8 classes, sees attached list, and wherein center coal gas exponential sum edge coal gas index is the ratio of furnace roof center gas temperature and furnace roof edge gas temperature and stock gas medial temperature; Going out slagging index blocks up the time for system's judgement time deducts last time.
As shown in Figure 2, diagnositc system of the present invention at first carries out after to the raw data computing judging based on the working of a furnace of example, if can in the case library of system, search the example that is complementary with it, can export as judged result, when the search failure, restart conventional knowledge base, carry out reasoning and judging based on conventional knowledge.The representative instance of main storage operation of blast furnace process is then stored in the conventional knowledge base with rule, parameter and the represented blast furnace operating knowledge of process form in the case library.Case library and conventional knowledge base can be carried out knowledge maintenance and renewal at any time, constantly investigate important parameter, to improve system performance.
As shown in Figure 3, blast furnace diagnostor of the present invention system comprises temporal diagnosis subsystem, stage diagnostic subsystem and real time data accumulation and dialogue service subsystem.The present invention once carried out scanning collection to option data in per 10 minutes, and send into the temporal diagnosis subsystem and carry out computational analysis, make judgement with good, attention, evil idea, according to each data items the size of working of a furnace influence is made weight calculation then, and with good, note, bad judgement made in classification, according to each classification the working of a furnace is influenced size more at last and make weight calculation, make the instantaneous working of a furnace and always judge with good, attention, evil idea; The stage diagnostic subsystem can be with the data of arbitrary section plural temporal diagnosis in the cycle in past as process object, with the process of similar temporal diagnosis to the stove shape in this stage make, attention, bad total judgement, both just can make comprehensive judgement to the operation of blast furnace situation at combination, and can be to passing to judge the development trend of conditions of blast furnace in the future.
The present invention is owing to adopt data communication method that the data of blast furnace process machine to the blast furnace field real-time acquisition are sent to by a station server and two data handling systems that microcomputer couples together by network, online service at a distance, facility investment is few, be easy to safeguard, the data reserves are big, and system extension is good.The present invention is to carry out analysis and judgement based on case library and conventional knowledge base, expand center and edge coal gas index especially, gone out data options such as slagging index, it is more reasonable that management project is selected, and adopt instantaneous and stage two kinds of judgment modes combinations, analysis and judgement mechanism is reasonable, and coincidence rate can reach more than 85%.
