The present invention discloses an object deformation electromagnetic monitoring device and method. An electromagnetic nondestructive testing method is employed, the device comprise a plurality of electromagnetic detection coils, an electromagnetic detection instrument and a monitoring data management system, the electromagnetic detection coils are distributed and fixed at the surface of the monitoring portion of a monitored object in the cascading mode or are embedded and fixed in the monitoring portion, and the electromagnetic detection coils are distributed and fixed in the mode of a linear array, or a area array or a space three-dimensional array according to the monitoring portion structure features of the monitored object and the monitoring requirement, at least one electromagnetic detection coil is taken as an exciting coil and is electrically connected with the signal exciting end of the electromagnetic detection instrument, the other electromagnetic detection coils are receiving coils and exciting coils and are electrically connected with the signal receiving end of the electromagnetic detection instrument, the changing of induction current signal parameters of the electromagnetic detection coils electrically connected with the signal receiving end of the electromagnetic detection instrument is monitored to indirectly monitor the structure state changing of the monitoring portion of the monitored object so as to obtain a real-time effective structure state changing monitoring result, and therefore the object deformation electromagnetic monitoring device and method are especially suitable for the asymmetric deformation monitoring work of a symmetrical object.
Description
technical field [0001] The invention relates to a nondestructive monitoring device and method, in particular to an object deformation electromagnetic monitoring device and method. Background technique [0002] At present, the structural health monitoring technology of facilities and equipment has extremely important application significance in the safe operation of facilities and equipment. For example, bridges, buildings, dams and other facilities should use effective monitoring technology to monitor their structural deformation changes during their operation, but so far no effective and reasonable monitoring technology has been applied to actual projects. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an object deformation electromagnetic monitoring device and method, which adopts an electromagnetic non-destructive detection method to realize dynamic monitoring of object deformation. ...
