System and method for multiple pipeline ultrasonic non-destructive detection and automatic detection for three-dimensional modelling locating dead pixels

Abstract

The invention discloses a system and method for multiple pipeline ultrasonic non-destructive detection and automatic detection for three-dimensional modelling locating dead pixels. The system for multiple pipeline ultrasonic non-destructive detection and automatic detection for the three-dimensional modelling locating dead pixels comprises a high-pressure pulse emission module, a signal processingmodule, a probe lifting system, ultrasonic wave probes, depth counters and a host computer. Each ultrasonic wave probe comprises an ultrasonic wave emission transducer and a receiving transducer correspondingly. Cables are connected to the rear of the ultrasonic wave probes and fixed to cable grooves. Photoelectric counters are installed on the cable grooves, and the cables pass through the photoelectric counters. Each depth counter is constituted by combination of a cable coated with black and white paint at an interval of 0.5cm and a corresponding photoelectric counter, and each depth counter is connected with the host computer. In the probe lifting system, the ultrasonic wave probes are controlled to rise and fall through a stepping motor by the host computer according to information of the depth counters. According to the system for multiple pipeline ultrasonic non-destructive detection and automatic detection for the three-dimensional modelling locating dead pixels, real-time comparison is conducted through relative standard data and detection data acquired from calculation and pre-measuring of pile foundation, and the detection time is saved.

Description

technical field [0001] The invention relates to ultrasonic non-destructive testing of foundation piles, in particular to an ultrasonic non-destructive testing system and a detection method for porous ultrasonic three-dimensional positioning of bad points. Background technique [0002] The ultrasonic foundation pile non-destructive testing system mainly judges the integrity of the foundation pile through the acoustic parameters such as the propagation speed, amplitude and frequency of the sound wave in different media. At present, the existing detection method: through the acoustic tube of the pile foundation, the ultrasonic transmitting and receiving transducer is used to transmit and receive the acoustic wave data, and the position of the defect can only be determined on a section, and it is impossible to specifically determine the position of the defect in the foundation pile. specific three-dimensional position. [0003] At present, the existing ultrasonic non-destructiv...
