In this research, we propose SOAP (Simple Object Access Protocol) agents to develop a cross-platform remote monitoring and control system. All independent and dispersal control systems in the plant, via XML standard object format and HTTP communication protocol can gather supervisory management information. This system can improve the ease of use in system maintenance and upgrading, in-system communication and reduce the complications involved in developing a remote control system. The objective of this study is to combine the Intranet, a personal computer and the Modular Production System(MPS)to develop architecture for a SOAP- based remote supervisory control system, without the constraint of fire wall disturbance. In this study, we employ the MPS in the Automation Laboratory of Chung-Hua University as a test platform to construct an Internet supervisory control system that includes communication, user interface, and MySQL database. The database collects the production control and process data to support the production planning, quality control, capacity planning, and shop floor monitoring. In addition, the client can request the current status of production line via WWW inquiry. These can allow equipment supplier/customer to perform supervision, analysis, study, and processing in real-time in order to decrease recovery time when the equipment is off-line. Thus the productivity and the effective use rate of equipment are increased. |
