Remote fault diagnosis system for spinning machines based on WebService and OPC technology

For the purpose of providing an accurate,fast,and low cost remote fault diagnosis and trouble-shooting for textile enterprises,an Internet-based remote diagnosis system for spinning machines was developed,which consisted of spinning machine information service system,remote diagnosis center and remote-experts.OPC technology was used to collect fault data on field,WebService technology was adopted to transfer the fault data,and expert system technology was applied during the diagnosis to assist the remote-expert.The remote diagnosis center played a role as the core in the entire system.In order to realize the direct communication between the diagnosis center and the upper computer,the web service was published by the remote diagnosis center and invoked by the upper computer on field.Moreover,the diagnosis webpage was published by the remote diagnosis center and browsed by remote-experts to achieve remote diagnosis for failure spinning machines.Compared with traditional remote diagnosis system that required the support of enterprise internal information system.The system is more practical for textile enterprises due to its flexibility,simplicity and expandability.
