Intelligent terminal used for metal damage detection

Abstract

The invention relates to an intelligent terminal used for metal damage detection, comprising a processing mechanism and a detection mechanism, wherein the processing mechanism comprises an electric cabinet, a power source and a connecting metal sheet; elements in the electric cabinet include a single chip microcomputer, an amplifier and an A / D converter and a voltage comparator; the detection mechanism comprises a position sensor, a magnetic field coil, a translation cylinder, a translation plate, a containing box and a Hall sensor; the translation plate, the position sensor and the magnetic field coil are aligned to one another; the translation cylinder is connected with the translation plate; the Hall sensor is located in the containing box; the containing box is located above the magnetic field coil, the containing box has a plurality of connecting electrodes, the plurality of connecting electrodes are respectively electrically connected with the position sensor and the Hall sensor;and the connecting metal sheet selectively forms electric connection with the connecting electrodes. The intelligent terminal can accurately control the metal moving speed and position, can avoid thesituation of missing inspection, and is accurate in detection.

Description

Technical field [0001] The invention relates to the field of metal damage detection, in particular to an intelligent terminal for metal damage detection. Background technique [0002] Metal non-destructive testing is a method of using flaw detectors to inspect the internal defects of metal parts (such as hidden cracks, blisters, impurities, etc.). Currently, magnetism, X-rays, gamma rays, ultrasound, etc. are usually used to inspect and detect internal defects in metal materials. [0003] In order to avoid the existing detection methods from adversely affecting human health, Chinese Patent CN102928505 discloses a portable magnetic metal fatigue detection method. The method is to use an electromagnet coil to generate an external magnetic field near the metal to be measured, move the probe on the surface or contour of the metal to be measured, measure the magnetic permeability of each position, obtain the Hall voltage, and then establish the Hall voltage. The relationship curve bet...

Problems solved by technology

[0004] However, the existing detectors can only detect metals by moving the probe manually, and since the speed and position of the movement cannot be precisely controlled by the human hand, there may be missed detections
