Research On Network Monitoring Control System For Composite Filament Winding Equipment And Machine

In the field of forming processes for composite materials, filament winding forming process is widely used because of its good performance. With the development of filament winding technology, the equipment for filament winding forming processes are also improved continually. The computer, communication and network technology, which are under rapidly developing, are adopted more and more by enterprises. This results in the fact that the traditional manufacturing methods, which take the equipment as separate production units, can not follow up the automatization trend of filament winding manufacture. So it is one of the important direction in the field of filament winding manufacture to monitor and control equipments using network technology.In this paper, we take several filament winding equipment as the monitoring control objects, which are developed by Institute of Filament Winding Composites Equipment of Wuhan University of Technology. After providing the collective structure of network monitoring control system, some related technology is explored and researched. The main tasks undertaken in the papers are as follows:(1) Construct of monitoring control network. Using the industrial Ethernet technology, we connect many filament winding machines and auxiliary equipments into a small monitoring control network, which can also be connected with enterprise network or Internet.(2)Implement of monitor and control for field equipment. RS-232(485) serial communication criterion TCP/IP protocol, Client/Server mode and customed upper communication protocol are applied to this system to implement local or remote monitoring control for the filament winding equipment and data exchange between equipment and upper network.(3) Production management network realization. Taking the production as the center, has established the simple production management process, while include the material purchase, the production sale and so on. By the peer-to-peer network, data has been exchanged between each department to achieve the good coordination.(4) Monitors software establishment. Used Microsoft Corporation the Visual C++ 6.0 program, and based on the object-oriented programming thought, develop the good interaction contact surface the monitoring software. The equipment by the client/server pattern carries on the data exchanged. And the management between the departments to carry on the data exchanged by the peer-to-peer network pattern.
