Holonic Supervisory Control and Data Acquisition for Heat Treating Process

Energy conservation and management continues to be of critical importance to the heat treating industry. With the cost of energy reaching record levels, the need to control what equipment is operating at proper temperature and what process specifications are ensured have become important factors in heat treating. With the analysis of holon the Holonic Supervisory Control and Data Acquisition (HSCADA) architecture is proposed. The approach is addressed to integrate systems in Small and Medium Enterprises (SME) of China when the use of commercial integrating software is reduced due to high cost and poor adaptability to SME from developing countries. The scope and advantages of this approach are discussed. Finally, a case study used in a used in small of heat treating workshop is presented to demonstrate the effectiveness of the proposed approach.
