Research Of Rotary Dump Health Monitoring And Diagnosis System Based On FBG Technology

Rotary Dump is a very specialized bulk material discharge system, which used to train loaded with the bulk material over disposal of its operation status monitoring and fault diagnosis has become a hot topic. Follow the "advanced predictive maintenance to replace the time-based preventive maintenance," repair of modern philosophy, in order to achieve predictive maintenance to be able to overturn the long-term security and stability of machine operation, study the health status of its online monitoring and evaluation system is imperative.Health monitoring and evaluation techniques related to testing technology, analysis technology, information technology and artificial intelligence fields are interdisciplinary integrated systems engineering, directly and fully reflected the Rotary Dump of a country to safeguard the level of manufacturing and management. Conditions because of the limitations of testing technology, mainly using resistance strain gauges, vibrating wire sensors and electromagnetic type of testing technology, it is difficult to achieve Rotary Dump force the state of the structure of a long-term reliable monitoring and real-time dynamic data acquisition and accurate fault location.Morey first time since 1989 referred to the fiber grating used as a sensor, the fiber grating sensor has been extensive attention worldwide. The emergence of fiber grating sensor, so that large-scale structure of online health monitoring possible.In this paper, Fiber Bragg Grating sensor technology development and current status of research, stress the use of fiber Bragg grating sensors, fiber Bragg grating demodulator device, combined with relevant experts Rotary Dump knowledge, based on Fiber Bragg Grating Sensor Rotary Dump-line monitoring of a design method of analysis of expert knowledge Rotary Dump set up the knowledge base and reasoning mechanism relevant to study the health status of Rotary Dump analytical methods. In this paper the main points include:(1) Studies the development of fiber Bragg grating sensing the status quo, combined with monitoring requirements Rotary Dump to study the fiber grating sensor, demodulation, the principle of sensor networks.(2) Studies Rotary Dump and structural properties of the metals analyzed Rotary Dump metal structure of the phenomenon of failure and its influencing factors.(3) According to the different key points Rotary Dump, designs fiber grating sensor points program.(4) Uses Rotary Dump Knowledge, sets up knowledge rules and reasoning processes, implements of the abnormal reasoning analysis of monitoring data for the Rotary Dump machine maintenance decision support.
