Abstract

Three layers of petrochemical farm tanks monitoring system structure were presented based on B/S, including software and hardware designs of bottom control network based on CAN, interface layer server and top layer designs. That middleware WebSnap and ActiveX ADO were used to design Web server is discussed in emphasis. Communication mechanism between Web server application and control program based on CANmini adapter was discussed. Connection of Web server application and database was also discussed in the paper. System debugging has been completed, and exchange with CAN bus data and Internet information has been realized. The system has wide application in petrochemical industry.
