Description

TECHNICAL FIELD [0001] The present invention relates to a steel process control system,

In particular, the present invention relates to a steel process control system and method, and more particularly, to a steel process control system and a steel process control method, which are capable of dynamically changing an interface environment for each dynamic engine required for a steel process, System and method.

In the existing steel process, sensor measurement devices, video devices, and controllers manufactured by a number of manufacturers exist, and in developing software supporting these devices, a software development library provided by the manufacturer is used for development .

Therefore, when software for sensor measurement devices, video devices, or controllers manufactured by a new maker is developed, there is a problem that programming must be performed redundantly due to the change of the programming interface environment.

In addition, when a software system is developed using measurement devices and video apparatuses of different makers, there is a disadvantage in that synchronization of data analysis is not supported because synchronization function between software systems is not supported.

In other words, when the programming environment is changed through the change of various measurement devices and video devices, a software system that dynamically sets interfaces automatically and transmits and receives data is needed instead of manually programming them.

Another problem is that there are PLC (Programmable Logic Controller) and DCS (Distributed Control System) manufactured by various makers in the steel process line. When real-time operation information is transmitted and received through these controllers, In addition, if the interface environment and contents of the transmission / reception information need to be changed, the interface code and the source code indicating the contents must be re-checked. This leads to a problem of redundancy and inefficiency of software development.

In the past, source codes corresponding to mathematical models have been statically programmed to derive control factor values for controlling the steel process. Therefore, when reconstruction and modification of the equation model is required, there is a problem that the operation must be stopped and the system must be operated again.

The reconfiguration and modification of such a model is disadvantageous in that it is not possible to dynamically mount it through automatic change and reconfiguration during operation. Therefore, it is necessary to dynamically manage the equation model for steel process control and also to be able to reconfigure and change during the operation.

In the conventional steel process, when the measurement and operation information are stored in the database, methods such as ODBC and DAO are mainly used as the storage interface means, and this can also be changed according to the type and configuration of the database, It is necessary to modify the source code developed manually and there is a disadvantage that the interface can not be changed dynamically.

Also, when receiving the operation information from the SCC in the existing controller, there is a problem that the source code must be manually written again when the interface environment and data structure to be transmitted and received need to be changed.

In the conventional steel process, a structure and software for a plant control system are statically mounted on a general-purpose personal computer to control the plant by transferring the functions of a plurality of PLCs (Programmable Logic Controllers). However, When the data structure of the operation information and the operation formula model are changed, the change of the software is corrected statically and the change of the software can not be reflected in real time during the operation.

In addition, when the criterion for evaluating the validity of the computation result data is changed, there is a problem that it can not be reflected dynamically, and thus there is a disadvantage in that the contents can not be reflected during the operation in real time.

That is, in the related art, since the system structure and the software are statically set, there are various problems as described above. When the interface environment and the data structure of the system information are changed, the system is stopped statically And causes the problem to be restarted again.

The dynamic reconfiguration that can automatically reflect the changes of the software development automation and hardware environment and process control environment as the kinds of video equipment, measurement equipment, control systems and databases used in the steel process measurement control area increase. Technology is emerging as a major issue. There is also a need for a technology environment that can dynamically change and reconfigure the process control factor values, which are the resultant values and the mathematical models used to control the process in the steel process.

Accordingly, in developing steel measuring and control software for various imaging devices, measuring instruments, control systems, databases, etc., used in a steel process, the present invention provides an interface environment for transmitting and receiving corresponding information and a data structure of transmitted and received information dynamically And to provide a steel process control system and method that can be reflected in real time during operation.

In addition, the present invention can be applied to the management of mathematical expression models for deriving process control factor values, in which a control source code corresponding to a mathematical expression model can be automatically and dynamically changed without modification, And to provide a steel process control system and method that can control the process in real time.

In addition, the integrated monitoring diagnostic screen system shows the current measurement, control status, and operation status to the user in real time, and shows the structure and technology that can control the state of the dynamic engines constituting the steel process control system. It is an object of the present invention to provide a steel process control system and method that can automatically build software for steel measurement and control applications that can be used in various steel process lines.

As a means for solving the above problems, a steel process control system according to an embodiment of the present invention includes a dynamic setter for grasping and notifying changes of engine interface information and data structure; A plurality of dynamic engines for changing the interface environment and the data structure of information to be transmitted and received by reflecting changes in the engine interface information and the data structure, and transmitting and receiving the measurement information and the operation information; A dynamic model engine for deriving a process control factor value by turning an expression model using the measurement information and the operation information and providing the value to at least one of the plurality of dynamic engines; And a data conversion engine converting the measurement information and the operation information output from the plurality of dynamic engines into a data form recognizable by the dynamic model engine and providing the data to the dynamic model engine.

The number of mathematical models that can be managed by the mathematical model list can be as much as the amount of memory supported by the hardware, and the number of mathematical models can be considered to be unlimited.

Also, the dynamic model engine 110 can check the data field indicating the desired use of the mathematical expression models that the user desires to use in the mathematical expression model list, and dynamically select the data field to use the mathematical expression model. This is because, in the existing steel process, when the modification of the mathematical models is stopped, the existing operating systems are stopped, and the source code of the program corresponding to the mathematical expression model is manually corrected, and the source code is compiled, Thereby eliminating the inefficiency of.
