Design and Implementation of Distributed Monitoring Control System of Vacuum Furnace

According to the demands of high performance and reliability of vacuum braze welding, the traditional hand-controlled is replaced by PLC automatic control program, so the relevant equipment and operational parameters and technological process are organically coordinated. In order to enhance the level of automation in vacuum plant and the quality of products, the distributed monitoring system with practicality and high efficiency is adopted to exert advantages of centralizing management and distributing control. The control strategy for developing the intelligent fuzzy integrated PID parameters obviously improves the precision of temperature control. The fact indicates that the control system markedly enhances operational efficiency and product quality.
