The history state query is used for a user to query the data of the running state of the blast furnace in the past time period, and the data of each time period is stored through a dictionary and is subjected to history query.
While the invention has been described in terms of preferred embodiments, it will be understood that the invention is not limited thereto, but is capable of modification and variation in light thereof by those skilled in the art without departing from the principles of the invention.
According to the invention, various attributes of physical equipment are mapped into a virtual space through various digital means such as a design tool, a simulation tool, the Internet of things and virtual reality to form a digital mirror image which can be disassembled, duplicated, transferred, modified, deleted and operated repeatedly, so that the understanding of an operator on a physical entity is greatly accelerated, a plurality of operations which cannot be completed originally due to physical condition limitation and dependence on the actual physical entity can be realized, such as simulation, batch duplication, virtual assembly and the like, so that the physical equipment becomes an accessible tool, and people can be stimulated to explore a new way to optimize design, manufacture and service.
As long as the measurement is possible, improvement can be achieved, which is a true that is not a change in the industrial field. Accurate measurements of various attributes, parameters, and operating conditions of physical entities, whether designed, manufactured, or serviced, are required to achieve accurate analysis and optimization. However, the conventional measurement method must rely on expensive physical measurement tools, such as a sensor, an acquisition system, a detection system, etc., so as to obtain an effective measurement result, which can definitely limit the coverage range of measurement, and often cannot be used for many indexes that cannot directly acquire the measurement value. The system can collect the direct data of the limited physical sensor indexes by means of the Internet of things and big data technology, and infer some indexes which cannot be directly measured originally by means of machine learning by means of a large sample library.
The existing product life cycle management can rarely realize accurate prediction, so that the problem hidden under the appearance cannot be predicted in advance. The digital twin can be combined with data acquisition of the Internet of things, processing of big data and modeling analysis of artificial intelligence, so that evaluation of the current state, diagnosis of problems in the past and prediction of future trends are realized, analysis results are given, various possibilities are simulated, and more comprehensive decision support is provided.
In the traditional industrial design, manufacturing and service fields, experience is often a fuzzy and difficult-to-grasp form, and the fuzzy and difficult-to-grasp form is difficult to be used as a basis for accurate judgment. A key advance of the system of the present invention is that expert experience, which was previously unavailable, can be digitized by digitizing means, and provides the ability to save, copy, modify and transfer.
