Fig. 2 is the process flow diagram of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further to describe in detail.
Referring to Fig. 1, the present invention includes operator's console and microsystem, be provided with steel rolling analog simulation device in the microsystem, steel rolling analog simulation device comprises model computation module, technological process display module, data acquisition module monitoring display module, training and examination module.
Model computation module receives the control signal of operator's console input, as calculated after, generate the process data that respective virtual is produced.Model computation module is the important component part of system, is responsible for carrying out exchanges data with other modules, and provides real-time video data for the technological process display module.This module has related to following basic model: the motor model of main mill, roll gap model, roll-force computation model, rolled piece deformation and temperature model, electric machines for roller model, throw steel model, change the steel motion model, electronic and hydraulic pressure depresses model, manipulator motion model, sideslip model etc.
The process data that the technological process display module generates model computation module is drawn the generation virtual scene and is shown.DirectX shape library technology has been adopted in the realization of technological process display module.Whole virtual scene can be divided into static what comes into a driver's and dynamic what comes into a driver's two parts according to motion state, in order to improve the real-time of system, quiet, dynamic what comes into a driver's has been adopted different mentalities of designing respectively.It mainly is the process of a modeling that static what comes into a driver's generates, and dynamically the what comes into a driver's generation then mainly is the dynamic driving of model data.The motion of rolled piece and deformation are that the steel plate that calculates according to simulated program relative position and the data such as length and width height on roller-way realize.What comes into a driver's has used the matrix function among the DirectX on realizing, realizes by matrixing.In the operation of rolling, will carry out several usually and change steel operation to reach rolling requirement, promptly the friction force by roller-way turns over 90 degree with steel plate and is rolled.After steel rolling finished, the center line of steel plate tended to depart from rolling centerline, with the steel plate folder just should enable manipulator this moment, otherwise steel plate is departing from process milling train under the state of rolling centerline, can the influence of rolled quality.In addition if the situation of steel plate sideslip also should be carried out centering with manipulator.Therefore change steel and manipulator is technological process and a process equipment indispensable in the operation of rolling, the vision of this part realizes similar to the workpiece motion s part, also used coordinate transform and the modeling transformation among the DirectX, by real-time parameter transmission, the visual effect that realizes changeing steel and manipulator.
Data acquisition module is gathered the field data that rolling process produces in real time, after amplification, isolation, Filtering Processing, converts digital signal to, transmits to the upper strata by computer network.This module adaptive control needs the physical quantity in the multiple operation of rolling is carried out data acquisition, analyzing and processing, and adjusts operation of rolling parameter according to controlling models, makes it to be in optimum condition.As sheet metal thickness of roll-force, rolling temperature, drafts, mill speed, rolling front and back etc., then need sometimes after the related parameter analyzing and processing is arranged, to carry out emulation.Data acquisition module is made up of PLC, various sensor and some analog input cards, detects field datas such as milling train, kink and control box in real time.Simultaneously, system with analog quantity or digital quantity signal and operations such as draught pressure, tension force, kink sensor, hot metal detectors, the switching value signal such as stop, send into the I/O expansion module of PLC system respectively by line, after amplification, isolation, Filtering Processing, convert digital signal to, transmit to the upper strata by computer network, finish producing rolling data acquisition.
The monitoring display module receives the digital signal that data acquisition module is carried, and adopts the PIC automated procedures to simulate the supervisory system of true enterprise, and operation and monitoring interface complete simulation are passed to virtual display device to the key message that collects and shown.
The training and examination module comprises reference record module, parameter database, examination comparison module, standard database.The reference record module is noted the procedure parameter of trainee's substantial length of operation, write in the parameter database, the examination comparison module adopts open subjective evaluation mode that data are carried out analysis and evaluation, by with standard database in the contrast of data, can the rapid evaluation operation of rolling in trainee's score situation.
Referring to Fig. 2, workflow of the present invention is: the operative employee sends operational order by operator's console to model computation module, model computation module is calculated according to the instruction of receiving, obtain operational order result of calculation, result of calculation shows in real time by the technological process display module, simultaneously, the steel rolling information of the real-time collection technology process module of information acquisition module, and convert the real-time information that collects to digital signal and upload, monitoring display module receiving digital signals, and carry out analyzing and processing, key message is shown by virtual display device, the information that the operative employee shows according to virtual display device is adjusted the control command of operator's console, thereby is finished the simulation milling process.
Certainly, above-mentioned explanation is not a limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also belong to protection scope of the present invention.
