Research On Monitoring System Of Rotation Machine

According to the project that contains the study and design of state monitoring and fault diagnosis of large crucial equipments in a certain domestic oil company that circumrorate in high speed, This paper is made. Based on the detailed analysis of the old Monitoring and Diagnosis system, according to the requirement of this new system, the whole design and funtion of this system is established. This paper makes detailed analysis of data acquire system and developed own data acquire card. This paper also gives the new design of data management system based on the analysis of old data management system. The main content of this paper is gives in the next paragraphs.Chapter One introduced the signification of monitoring and fault diagnosis of rotation machine first, then discuss the developmental actuality of its trends.Based on the research background.the research task is expressed.Chapter Two reviewed the history of distributed monitorin and fault diagnosis system of roation machine,gived the frame of this paper.Chapter Three gives the signification of the sensor of monitoring and fault diagnosis of rotation machine system. Based on the requirement of the monitoring and fault diagnosis system,this chapter analyzed the selection and fixing of the sensor.Chapter Four analyzed the pretreatment of the signals from sensor, then this chapter gives the design and checked of pretreatment circuit.Chapter Five designed the data acquire cards of the monitoring and fault diagnosis system. The data acquire cards include three kinds: Keyphase card, high speed data acquire card and low speed data acquire card. The process of the research, the design, the development is expressed detailed in this chapter.Chapter Six gives the new design of the data management of the monitoring and fault diagnosis system based on the analysis of the old managment.Chapter Seven introduced the software of data acquirement system and data management. This chapter also gives the monitoring example of the system.In the last Chapter, all of the works in this dissertation are summed up. The future research of monitoring and fault diagnosis is prospected.
