With continuous improvement of computer science and network technology, traditional industry monitoring network system (IMNS) based on server/client pattern can not supply enough self-adapting ability and satisfy the increasing demand of modern industry monitoring, so a kind of intelligent embedded IMNS realization method based on universal plug and play (UPnP) was put forward in this paper. According to the special demand and environment characteristic of industrial monitoring fields, the topological model of IMNS was established around UPnP. System modules' partition and data interaction process were constituted by modularization theory which can make this system reconfigure and optimize easily. IMNS nodes and monitoring center were designed and realized using embedded system technology, and its industrial application instance was finished. Industry fields experiments proved that this system can obtain the anticipated functions of seamless link, zero-configuration and self-recognition using UPnP service program, and it can break through the limitation of enterprise internal gateway and real-IP to realize online remote monitoring and real-time diagnosis by gateway support of UPnP.

Aiming at some problems of embedded industry monitoring system graphic user interface (IMS-GUI) such as large occupation space, bad configuration ability and poor real-time performance, an embedded IMS-GUI components library realization method based on Qt/E was put forward. The Qt/E library file was tailored according to basic requirement of IMS. Using multi-thread method, system parallel processing abilities of data collection, analysis and display were enhanced, and real-time performance and rapidity were guaranteed. By internal communication interface of Qt, the message mapping mechanism which would not require call-back was realized, context switch speed was improved, and GUI development process would become simply. Based on modularization principle, combined with some related industry monitoring and fault diagnostic algorithms, GUI shared components library oriented to IMS was developed by primary C language, that could resolve the problem of cross-platform applicability and be configured and tailored for specific demand of users. Industry experiments proved that GUI developed by the components library has small occupation space and high real-time performance, can stably run in embedded platform environment, and supply powerful technical support for the interactivity of IMS.

Embedded fault diagnosis technology requires high pertinency and small occupation space. Traditional fault diagnosis system can not satisfy the demand above. Aiming at this problem, a kind of embedded fault diagnosis expert system (E-FDES) based on CLIPS and ANN was brought forward. FDES and its relative technology were discussed, developing environment and design tool chain for E-FDES was established in Linux environment. Using modularization theory principle, system re-configuration and expansion ability were guaranteed, and data process components and graphic user interface components could be reduced to meet the embedded system running requirement. By application program interface of CLIPS and Protege plug-in, knowledge base and rule base were realized, that decreased the developing time of system inference engine and reduced source occupation space. Industry experiments prove that this system runs stably in ARM-Linux embedded environment, switch smoothly and can recognize some common faults for the devices monitored.
