| Equipment remote monitoring and fault diagnosis is a integrative subject, the main aiming at remote examining about large-scale equipment .In recent years, With the insistent need for high safety, stability and longevity of the equipment in the modern industry field, traditional methods of monitoring and diagnosis are more and more incommensurate. The modern remote monitoring and diagnosis which based on sensor, signal analysis , computer, network communicate and intelligent diagnosis technology acquired fast development.Thus, remote monitoring and fault diagnosis is becoming more and more conveniency , high efficient and nicety.This dissertation focuses on the study of real time monitoring of multiple signals, and implemented web sites. Against the difficulty in developing and maintaining, defects of traditional monitoring and fault diagnosis system based on C/S mode, B/S+C/S mode is put forward to establish a remote online monitoring and fault diagnosis system. Most the development, maintenance and upgrade are beared by the server. Client only needs to install the Internet Explorer or Engine can master the spot status in time through the URL.This dissertation analyzed the present development process of the remote monitoring and fault diagnosis technology at home and abroad, and made an in-depth discussion on the assignment of this issue, study the system frameword, system network structure and system software platform from the whole system, and put forward the overall designed ideal of the remote monitoring and fault diagnosis system. And then this dissertation studies signal sampling, analyzing and preprocessing technology, design and implement the local data acquisition system which based on Virtual Instrument and other based on the remoter communications of GPRS. Through study and research on the whole system database, make choice of MS SQL Server 2000 database management system, design and realize the system database. Then, Accroding to the requirement for the system and research on network technology, exploit the network platform of the system.We analyze several related key technique and discuss the issues that need to be solved deeply.In the later, the dissertation design and realize the overall of the remote monitoring and fault diagnosis system for the compressor based on design criterion of software engineering . At last, introduce the BP expert system.The research of this dissertation possess theory study and use value. such a system is of portability and expandability, whose exploitation has got prodigious reference value for the toward practicability business software. |
