Abstract: | At present, the electric vibration table automatic controller uses PID as the control core, its anti-interference ability is weak, the starting time is too long, which leads to the short service life of the controller. The design of PLC automatic controller for electric vibration table of rotating machinery is put forward. The PLC of the PLC automatic controller is designed as the main control unit, the overall structure of development of PLC automatic controller, using RS-485 serial port and EEPROM data memory of power module, LED display module, alarm module, details of improved communication module, signal acquisition module and memory module and other hardware devices; the automatic control function of the main program controller the software part of the LED display subroutine and interrupt, re programming, realize the optimization of automatic control effect of the controller, completes the design of rotating machinery electric vibrator PLC automatic controller. The experimental results show that the improved controller effectively improves the anti-interference ability of the electric vibration table of the rotating machinery, shortens the starting time of the electric vibration table, and prolongs the service life of the electric vibration table. |
