The Research And Design Of Wideband Integrated Data Optical Synchronous Network's Node Data Management

The main network used in Industrial Control nowadays is Fieldbus and Industrial Ethernet, which is proposed by world industrial group and equipment manufacturers. These Fieldbuses which are not completely opening to each other are incompatible and their transfer rate is low, further more the communication distance also limits within several kilometers. As industrial automation and control system is particularly emphasis on data reliability, security, and real-time, although Industrial Ethernet is widely used, inexpensive and has high speed of communication, the Industrial Ethernet is also restricted in applications.So the Wideband Integrated Digital Optical Synchronous Network(WIDOSNet) is proposed against this backdrop. The WIDOSNet which is a fire-new industrial control network is based on SDH, optical fiber communication, SOPC technology, and it uses the concept of on-chip data selection to complete the traditional functions of exchange. Moreover, it also has the flexibility of variable data bandwidth. The WIDOSNet provides high data bandwidth, and has the high ability of anti-jamming. It can satisfy the industrial control and multimedia transmission of data in areas such as real-time and reliability requirements, and the application prospect is very bright.The WIDOSNet is a bran-new network model which is designed by the team. This paper is committed to the research and design of the WIDOSNet's node data management, and its target is mainly the node system. First, the development of domestic and foreign industrial control network is researched in this paper. In order to understand the contents of node data management better, the paper introduces the WIDOSNet. And its components, functions, features and frame structure are described in detail. Second, the structure of node data management (It includes the node deserializer and the node serializer two parts.), work processes and functions are explored further. The paper analyzes the model, protocol and the characteristics of the typical control network, and the hardware circuit and interior functional modules of the WIDOSNet's node data management are researched and designed in light of the network's needs. As this network is a new network and the structures is complex, therefore the design maybe not mature enough. But it provides practice to deepen the design of the subsequent network model.
