Research On Java 3D-based Remote Operation And Control System For The Laser Micro-texturing Machine

With the developing of computer technology, communication and network technology, manufacturing systems are undergoing the simultaneous trends of flexibility, intelligence, and networking. Meanwhile, for the enhancement of people's environmental consciousness, man-beneficial has been one more trend for the manufacturing system. Computerized numerical control machine tools are regarded as the key equipments of the manufacturing systems, and which stand for the productivity and level of the enterprise. It will be an important trend for the manufacturing industry to make the CNC machine tools be operated and controlled remotely in the future.Firstly, the thesis expounded the overall structure, control system principle, and the hardware implementation of the control system of the laser micro-texturing machine. On the basis, according to the practical manufacturing demand, the function module of remote operation and control system was divided into five parts, and they were system information module, task management module, safety management module, remote operation and control module and online communication module.Secondly, the thesis discussed the theoretical system of computer network, which was referred to the construction of the remote operation and control system, and comparing with the remote monitoring and control systems in Client/Server and Browser/Server mode, the thesis proposed the overall framework of Browser/Server-based networked monitoring and control system on the laser micro-texturing machine. The system was divided into three layers, client layer, intermediate layer and field-devices layer. In this system, the browser embedded with Java 3D models offered cliens friendly and interactive interfaces. The application server in the intermediate layer answered for the control logic of the system. The field-devices layer presided over the data collecting of the running status and excuting the demands.Thirdly, the thesis expounded key technologies and the specific realization methods in the whole developing process of the system development. It adopted Java 3D technology to implement the 3D visualization modeling of the laser micro-texturing machine, and multi-thread technology to accomplish data collecting and storing for running status. Applet-Servlet-Database mode was to accomplish the data communication between distributed objects of client, server, and database, and Java native interface was used to realize the remote monitoring and operation on the laser micro-texturing machine. Testing results showed that the system could satisfy the practical application.
