In order to reduce the strong interference of aluminum electrolysis process, STD bus industry control machine which has strong anti-jamming ability is used as control host computer to improve control capability. Modularization and combination are applied in the hardware of the control system and the design principle of structure and the modularization are used in the software design. Advanced control idea and different control tactics are adopted in the system, based on the different working state of electrolysis trough to make sure that the electrolysis trough is at its best working state. The system software programs work with VC, and have several characters such as extension and good maintenance. The system has strong dependability and anti-jamming ability, convenient maintenance, good dynamic capability and running effect, and high precision of stabilization. Aiming at the complicated process control especially in the great disturbing producing course, STD bus industry control machine which has strong application can improve the control effect.
