Monitoring System Based on Virtual Instrument Technology
With the long influence of high temperature and stress, high temperature & high pressure steam pipeline of a thermal power plant will bring about creep damage or even tube explosion, which heavily threaten its safe operation. Therefore, the timely and accurate measurement of the pipeline creep is vital to the correct estimation of pipeline residual life and the prevention of various security accidents resulted from the pipeline high temperature creep.This paper put forward a new measurement method, which advanced virtual instrument and data base technology are introduced, and the non-contact precise electronic eddy sensor,converts the measurement of pipeline creep into high precise micro-displacement under the high temperature circumstance, and so completes the non-contact nondestructive examination.The test result is filed in history data base; an analysis and estimation are made on the pipeline residual life and a real-time supervisory information system is run by the LAN interface in Plant Level. It is of great practical exploration with the application of the virtual instrument technology to the Plant comprehensive supervisory information system, which has a good popularized future.
