The calculation and filtering of lubricating oil filling machine set data and PID control algorithm to adjust motor current after weight feedback are completed in the corresponding program. The dynamic data exchange technology is used to realize the data acquisition and transmission of the production site, and the data interaction is completed to make up for the shortcomings of complex control algorithms and data processing.
020-34563445The lubricating oil Filling machine conveys the oil through pipelines and the feeding system into the filling gun. Under the effect of gravity, the material bucket transmits the gravity to the weighing module, causing the elastic body of the metering module to deform. The strain gauge bridge circuit attached to the elastic strain beam loses balance and outputs A voltage signal proportional to the weight value. The signal is amplified by a linear amplifier and converted into a digital signal by an A/D converter After being processed by the single-chip microcomputer, the current weight of the filled material, various set parameters and working process status are displayed, and signals such as coarse feeding, fine feeding, weighing completion and upper and lower limit alarms are sent out.
The control section of the automatic filling machine mainly consists of an industrial control computer, an intelligent weighing display section, I/O interfaces and other components. The following focuses on the industrial control computer and the intelligent weighing display part. The industrial control computer is adopted as the upper computer, which can use windows or Linux operating systems and adopts touch screen technology.
The calculation and filtering processing of the data collected by the automatic filling machine, as well as the PID control algorithm for adjusting the motor current based on weight feedback, are all completed in the corresponding VB program. The dynamic data exchange technology is utilized to realize the data collection and transmission of the production site by InTouch, and at the same time complete the data interaction between VB and InTouch to make up for the deficiencies of InTouch in complex control algorithms and data processing, and the specific configuration process is given.
