Abstract
This paper from the loose parts of the harm, combining with the actual situation of the field, for first loop loose parts of the alarm signal after the scene recognition and diagnosis are introduced, respectively used in the diagnostic field listen to the sound of needle method, field data playback listening method and data analysis of linear positioning method, circle intersection method, hyperbolic positioning method, Newton iterative positioning method, contrast and analysis the advantages and disadvantages. And combined with field loose off parts of echo, the reactor internal structure characteristics, equipment operation state, through the positioning analysis method to determine loose parts quality and position, of first loop loose parts field diagnosis put forward own views, for follow-up of new project a loop loose parts detection system design reference.
