Abstract:: In order to optimize chromium electroplating process,improve plating operation environment and achieve the automatic control of plating bath temperature and other parameters,chromium electroplating bath temperature intelligent control system was designed. Hardware was assembled with PLC master and slave monitoring and control module. Bath temperature,equipments and instrumentation running status were monitored through Device Net bus,human machine interaction and PID algorithm online regulation.Practical application showed that the system could run stable,and was easily for human machine interaction. The system had achieved chromium electroplating process temperature and other parameters online control with high temperature control accuracy,and it could meet the plating production requirements.
