To improve the clarity and accuracy of detection, i.e., to improve the density of data acquisition points, the physical size of the sensor must be reduced.

In order to prove the technical effect of the ultra-high definition probe of the present invention, the following detailed discussion is made in conjunction with the accompanying drawings and specific applications:

example 1

Fig. 8 is a schematic diagram of an array layout of the detecting sensors 311 of an ultra-high-definition detecting probe 4 according to the present application, which can obtain ultra-high detection data acquisition density and ultra-high-definition defect data inversion imaging in internal detection of a pipeline defect. The physical size (the distance between the central points of the sensors) of the circumferential close arrangement of the sensors in the example in the figure is 3mm, and the circumferential distance of data acquisition is 1mm by using staggered array arrangement in the figure, so that the detection precision far smaller than the physical size of the sensors by 3mm is achieved. The detection probe 4 comprises two sensor array groups 3, the two sensor array groups 3 are arranged in a staggered manner, the PCB substrate 2 is designed into a whole structure with three staggered sections and connection, the detection probe comprises a first section 21, a second section 22 and a third section 23, wherein the sensors of the sensor array groups 3 in the first section 21 and the third section 23 are arranged in a staggered manner in a conformal manner in a circumferential direction (perpendicular to the moving direction), each sensor array group 3 comprises a data acquisition module 31, the data acquisition module 31 comprises 15 data acquisition sensors 311, other forms of conformal staggered arrangement can be adopted here, the data acquisition sensors 311 with more numbers can be designed according to the circumferential density requirements of sampling points, and the number of the data acquisition sensors 311 is not only 15.

The malposition arrangement of the plurality of data acquisition sensors 311 and the malposition arrangement of the sensor array group overcome the obstacle of the physical size of the existing sensor, and according to the design method, the sampling interval of the data can be reduced to be less than 1mm and far less than the common 3-6mm and the best foreign 1.5mm, which provides guarantee for the defect imaging of ultra-high definition and the ultra-high detection precision.

The pipeline detection has different principles and methods, takes the pipeline defect magnetic flux leakage detection as an example, and has the technical principle that: and detecting the defects on the tube wall by using the electromagnetic leakage effect generated when the defects appear. Generally, the pipe wall is smooth when being complete, so when the pipe wall is magnetized, as shown in fig. 7 (a), when the pipe wall has no defect, the magnetic flux loop has no disturbance, and the leakage magnetic field signal picked up by the magnetic sensor in the air is constant or negligibly small; as shown in fig. 7 (b), when a defect exists in the tube wall, the magnetic lines of force in the tube body are refracted (like leakage) at the defect interface, resulting in a variation in the leakage magnetic field outside the tube body. The defects of the pipe body can be identified by analyzing the detected leakage magnetic field signals in the actual pipeline detection process; the rough quantification of the defects can be realized by analyzing the characteristics of the leakage magnetic field signal such as form, amplitude and the like.

In fact, the extrusion of adjacent probes is close to and can increase the density of adjacent data acquisition points, the increase effect of the density of the data acquisition points can also be used for distinguishing or finding the deformation or the abnormity of the pipeline through the post-processing of data, the detection precision and the acquisition density of designed data points are influenced, and the beneficial effects are that reserved gaps can be designed and arranged between the adjacent conformal probes, and the gaps allow a plurality of probes carried by the pipeline detection device to smoothly pass through the obstacles or the deformed pipeline after being extruded and subjected to diameter change when the pipe is bent or deformed or obstacles appear in the pipeline.
