| In this paper, the continuous casting mold control system driven by AC servomotor torealize non-sinusoidal oscillation is taken as the background, understand on the basicworking principle of continuous casting of non-sinusoidal oscillation control system,directed towards two-stage computer control system constitute by the upper and lower,design rapid data communication and display based on upper PC WinCC monitoringsystem and lower PLC. Implement rapid data communication and display for thecontinuous casting mold control system driven by AC servomotor, and implement datastorage and flexible call by use database functions. So the rapid communication andhuman-machine interface design of mold oscillation control system has importantapplication value and practical significance.Firstly, introduction the basic working principle of the continuous casting moldsystem driven by servomotor to realize non-sinusoidal oscillation, and then introduce theoscillation waveform rule for servomotor driven continuous casting mold, which overviewthe basic hardware components and functions of the continuous casting mold systemdriven by servomotor to realize oscillation control system. overview of hardwarecomposition and function of the continuous casting mold control system driven by ACservomotor, And have preliminary design for monitoring interface between upper andlower computer systems. This is the foundation for back rapid data exchange and interfacedisplay between upper and lower computer.Secondly, the continuous casting mold control system driven by servomotor torealize non-sinusoidal oscillation, taking into account the characteristics of time variationof the mold displacement, the mold velocity and motor speed in the actual operation, thecomputer system can not achieve below 250ms rapid data real-time sampling, using theFM-458 and EXM-438 module of S7-400 PLC framework to achieve real time acquisitionfor the actual data. and the use of WinCC data archiving and S7-400 PLC AR-SENDfunction block implementation rapid data communication and display between uppercomputer and lower computer, realization of each 10ms real-time data acquisition of thesampled value. Thirdly, combine the test interface of data communication and display between thePC WinCC monitoring system and lower computer PLC, to achieve fast display ofreal-time samples on the interface of PC computer, and online real-time monitoring forvibration control system. Verify rapid data communication and display real-timewaveform of system between upper and lower computer.Finally, use the database of PC WinCC7.0 to realize the storage and analysis ofsample processing value, collected time-varying field data in the form of compressedpackets stored in the database, And achieve the query and flexible call of historical data bytaking use of the function of database query and recall. |
