Research On Network Monitoring Control System For Microcomputer Controlled Filament Winding Machine And Auxiliary Equipment

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 protocoK 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) Implement of video monitor based on network.Microsoft DirectShow technology , UDP protocoK Mpeg media format and stream media technology are introduced to implement the real time video monitor based on network for the field equipment.(4) Development of monitoring control software. Based on object oriented thoughts, the application software is developed using Microsoft Visual C++6.0 development kit, and is featured with good interactive interface, C/S mode, and local or remote monitoring control functions.
