This invention belongs to the field of nondestructive testing and relates to an automatic evaluation method, system, and equipment for ultrasonic phased array testing of welded pipe end faces. It aims to solve the problems of high subjectivity, low efficiency, and lack of digital traceability in manual inspection of welded pipe ends. The invention includes: acquiring spectral data from two circumferential directions, one vertical wall thickness direction, and one axial detection direction, and selecting target image data from them. For circumferential data, longitudinal non-layered defects are evaluated based on whether the signal parameters exceed a first preset standard; for vertical wall thickness data, layered defects are evaluated based on whether the signal indication magnitude exceeds a second preset standard; for axial data, inherent structural echoes are intelligently identified and filtered out based on a three-dimensional model of the pipe end and a path-amplitude difference fusion algorithm, and transverse non-layered defects are evaluated based on whether the residual signal parameters exceed a third preset standard. This invention achieves automated and standardized detection and evaluation of welded pipe end defects, improving the objectivity, efficiency, and quality traceability of the inspection.

The invention relates to the technical field of composite materials, in particular to a method for detecting the orientation degree on line. The method for detecting the orientation degree on line comprises the following steps: acquiring axial data, wherein the axial data is obtained by measuring along the axial direction of a moving fiber; obtaining radial data, wherein the radial data is obtained through radial measurement of the moving fiber; and determining the orientation degree according to the axial data and the radial data. According to the design, the orientation degree of the fibers is determined by integrating the axial data and the radial data of the fibers, and the detection result is more accurate.

An energy-saving positioning method for tire pressure detectors includes the following steps: the vehicle main unit determines whether the engine switch changes from on to off; each tire pressure detector records initial data of at least two axes (X, Y, Z); each detector periodically records subsequent axial data; the vehicle main unit sends an engine start signal to all detectors; each detector compares recorded values with the last recorded values to check for changes; the vehicle main unit evaluates position change messages from detectors and proceeds accordingly. If changes occurred, then go to Step 5A: the main unit skips automatic positioning and uses previous positioning data. If no changes occurred, then go to Step 5B: the main unit initiates automatic positioning. This method effectively reduces positioning frequency compared to traditional systems that require repositioning every engine restart, thereby achieving power conservation while maintaining system accuracy and reliability.
