Industrial Communication Protocols Data Resource Network Sharing Platform Development

Fieldbus is an advanced field industral control technology which was developed since the late 1980^th . Nowadays there are more than 200 types of Fieldbus protocols. For example, IEC 61158 Ed.4 which is widely used in measurement and digital data industrial control has 20 types about 8100 pages protocols. Fieldbus has rich data resources and already found wide use. But in our country, Fieldbus data resources are under a much bad situation: shortage, scattered, poor rate of sharing. Along with the widespread use of the technology, the requirment of sharing these resources become more and more important. Integerating the scientific data to improve the technical merit and competitive strength in the industrial automation field is extremly urgent.This paper is based on the foundation sharing project "Advanced Manufacturing and Automation" which supported by the Ministry of Science and Technology, researching and building the related subjects of industrial communication protocols based on internet, designing and developing a Expert System. The paper realized industrial communication protocols data resources sharing. After the network testing, good result has been reached.The mainly innovations and research results is as follows:First, Data Quality Control Criterion and Metadata Collection Standard, were I established based on the AMADSNP metadata criterion. They guaranteed the collection quality of metadata, which was the key point for the platform.Second, Industrial communication protocols data resources framework, which covered the resources about industrial communication protocols, was designed through analyzing industrial communication protocols data characteristics in detail. INTERBUS is introduced as the example to elaborate the framework's details.Third,To meet the practical requirement of the sharing network platform item and users, the industrial communication protocols data resources sharing network system was built, which was developed based on the AMADSNP template. The application function of the sharing network was extended by the expert system.Fourth,Considering users must have trouble in selecting the fittest one among the various of Fieldbus, an Fieldbus Selection and Analysis Expert System has been built which programmed by C# using Visual Studio.NET development platform,ASP.NET and SQL Server2000 background database. The ES can imitate as an Fieldbus expert to support a solution for website users.
