Before the reinforced concrete is used, a user inputs an inner diameter of the reinforced concrete manually, and at this time, a detection terminal (which may be understood as a measurement and adjustment terminal) of the system calculates positions to which the first link 100, the second link 206 and the third link 108 need to be adjusted according to the inner diameters, for the first use, the system firstly needs to extend into an inner diameter channel of the reinforced concrete, and when extending into the channel, the first link 100, the second link 206 and the third link 108 need to be adjusted again, so that the pulley 104 can slide on an inner wall of the inner diameter channel, thereby adapting to reinforced concrete with different shapes and different inner diameters, or other types of building materials, and a measurement sensor is arranged on the pulley 105, and during the detection, the length of the inner diameter channel passing through is recorded and fed back to the detection terminal. On the one hand, the length of the detected reinforced concrete can be measured, the length of the reinforced concrete is measured, the measured length data of the reinforced concrete can be directly used in the engineering process, the data of the reinforced concrete assembly in the reinforced concrete are suitable, the recording function is realized, people can conveniently find the reinforced concrete at the corresponding position from the drawing, and the working efficiency is improved. On the other hand, according to the length of the reinforced concrete, an initial detection position or an end detection position is selected as a reference point, so that a defect position point of the reinforced concrete is obtained during detection, a user is informed of the defect position point of the reinforced concrete, strength calculation is carried out on the defect, and whether the defect meets engineering requirements is judged. It should be noted that, the defects are various, such as that the reinforced concrete internal reinforcing steel bar assembly does not meet the requirement of engineering strength, the reinforced concrete has cracks, the reinforced concrete has too large crack volume, and the like. In addition, in the process of judging the strength of the reinforced concrete, a worker can judge whether the corresponding reinforced concrete meets the extreme value of the limit stress through inputting the limit stress required to be born by the reinforced concrete in the engineering drawing, and when the actual reinforced concrete does not meet the extreme value, the worker is marked and informed that the reinforced concrete does not meet the actual engineering requirement, and the reinforced concrete needs to be replaced or treated. One of the purposes of the system is to increase and improve the reliability, safety and durability of the operation structure, ensure the normal service life of the structure and reduce the maintenance cost of the structure. The positioning sheet 207 is used for monitoring the movement speed of the system in real time, and the speed of the pulley 105 is regulated by utilizing the positioning sheet 207, so that the system always keeps a speed running, and good basic performance is provided for detection.
The adjusting system 2 comprises a second fixed block 200, a plurality of guide rods 201 are arranged on the second fixed block 200, compression blocks 202 are arranged on the guide rods 201, and springs 203 are arranged on the compression blocks 202.

It should be noted that, through adjusting the position of the guide block 204, thereby promote the compression block 202 through cylinder or electronic jar, under the effect of spring 203, the compression block 202 moves to the adjustment position that adapts to reinforced concrete internal diameter, thereby drive first connecting rod 100, second connecting rod 206, third connecting rod 108, make pulley 105 remove to reinforced concrete's inner wall, detect reinforced concrete from inside to outside, thereby carry out the omnidirectional detection to reinforced concrete, can adapt to the reinforced concrete of various different shapes, like circular, square, irregular, the scope of detection is wider, detection efficiency is higher, thereby reduce the idle work in the engineering, improve on-the-spot staff's work efficiency.
Further, in a preferred embodiment of the present invention, the inspection system 3 includes an inspection substrate 300, and the inspection substrate 300 is connected to the inside of the first fixing block 103. The detection substrate 300 is provided with a plurality of luminous bodies 301 with openings along the periphery of the edge of the detection substrate, one end of each luminous body 301 is connected with energy supply tissues 302, and the energy supply tissues 302 are arranged on one side of the first fixed block 103. The luminous body consists of a plurality of light mirrors, wherein the light mirrors are provided with test points which are used as measuring tools for measuring whether a target detection object is defective. The light wave emitted by the illuminant is terahertz light wave, the terahertz light wave has penetrability, but does not cause radiation injury to cells of a human body, and the light wave can be suitable for high-precision detection on site. The pulley 105 is powered for movement by the powered tissue 302, providing a basis for movement of the pulley 105. Moreover, when the terahertz light wave penetrates through reinforced concrete, the time of the terahertz light wave penetration is inconsistent when a crack or an area injury of a large area exists. And the light wave emitted by the illuminant emits light wave to the periphery of reinforced concrete or other types of detection materials, the light wave penetrates into the reinforced concrete to detect the structural performance of the reinforced concrete, and when the limit stress born by a certain position is detected to be lower than the time limit stress required by engineering, the use of the reinforced concrete is not in accordance with the engineering. On the one hand, the condition of the internal reinforcing steel bars can be detected, and on the other hand, the cracks of the internal or external reinforced concrete can be detected, so that the bearing capacity of the reinforced concrete can be comprehensively detected. When the terahertz waves at different test point positions irradiate to the same position, the area is confirmed and authenticated by combining the detection results of multiple times after multiple times of detection (the area is detected to be cracked by the previous terahertz wave and the next terahertz wave), and the detection result is more accurate.
To sum up, this system not only convenient to carry makes things convenient for people to use in different scenes, can adapt to the reinforced concrete of different shapes, different diameters through adjusting the form moreover, and then detects it, does not receive reinforced concrete's length influence during the detection moreover, and this system can carry out inside outside extension detection at different diameters reinforced concrete, and the luminous body diverges the detection light all around, when passing through every detection position, can all carry out the omnidirectional detection to this position, and detection efficiency is higher. When the defects are detected, the intensity value of the defects of the reinforced concrete is calculated by utilizing multiple times of detection, so that the performance of the reinforced concrete is ensured, the idle work in the engineering process is reduced, the working efficiency is improved, the reliability, the safety and the durability of the operation structure are further increased and improved, the normal service life of the structure is ensured, and the maintenance cost of the structure is reduced.
In addition, the system can also detect the content of main substances in sewage in the sewer, and the sewage is often accompanied by various microorganisms, while terahertz waves have penetrability, but do not destroy intracellular proteins. In the detection process, terahertz adopts a spectrum detection method to carry out grey-scale treatment on images acquired by terahertz waves, different wave bands are displayed in terahertz spectrums of different substances, the technology is utilized to detect sewage, the system can adapt to all irregular sites, the position of the pulley 105 can be switched at any time, obstacles can be avoided, the system goes deep into a harsher underground environment, people are replaced to enter the dangerous environment, sewage detection, pipeline detection and the like of a sewer are carried out, and the system can specifically detect the content of each substance in the sewage, so that the sewage can be subjected to targeted treatment. In the pipeline detection process, before the pipeline enters the use stage, performance detection is carried out on the pipeline, such as detecting whether the pipeline leaks or not, and the diameters of some pipelines are too large, so that the pipeline is often not easy to detect, and therefore the position of the guide block 204 is adjusted, so that the compression block 202 is pushed by the air cylinder or the electric cylinder, under the action of the spring 203, the compression block 202 moves to an adjusting position suitable for the inner diameter of reinforced concrete, so that the first connecting rod 100, the second connecting rod 206 and the third connecting rod 108 are driven, the pulley 105 is moved to the inner wall of the pipeline, the inner wall of the pipeline is detected along, whether the pipeline meets the requirement of throwing use or not is judged, and any defective position can be accurately detected by utilizing the system detection, so that the problem is avoided at the beginning, and the working quality is improved.

The detection terminal carries out smoothing filtering treatment on the image by adopting a median filtering method so as to eliminate random interference noise of the image; the median filtering is a nonlinear signal processing technology capable of effectively suppressing noise based on a sequencing statistical theory, and the basic principle of median filtering is to replace the value of a point in a digital image or a digital sequence with the median of the point values in a neighborhood of the point, so that surrounding pixel values are close to the true value, and thus isolated noise points are eliminated. The method is to use a two-dimensional sliding template with a certain structure to sort pixels in the plate according to the size of pixel values, and generate a monotonically ascending (or descending) two-dimensional data sequence. The median filtering method is utilized to eliminate the interference noise of the image. Further, the image is further sharpened, contour edges and details in the image are enhanced, and feature pixel points are extracted. Here, the characteristic pixel point is understood to be a characteristic point of a large difference between an image when there is a crack or an irrational change of the reinforcing bar and an image when there is a normal reinforced concrete and a normal reinforcing bar, thereby extracting the difference.
Further, in a preferred embodiment of the present invention, the geometric data includes one or more of a length of the defect, a width of the defect, and a height of the defect.
Further, in a preferred embodiment of the present invention, if the detection result includes a defect, the area corresponding to the detection result is a defect area, including: and if the continuous detection results of the images are all defect-containing, determining the region corresponding to the image to be detected as a defect region. When the terahertz waves at different test point positions irradiate to the same position, the area is confirmed and authenticated by combining the detection results of multiple times through multiple times of detection (the area is detected to be cracked by the previous terahertz wave and the next terahertz wave), and the detection result is more accurate.
The above-described preferred embodiments according to the present invention are intended to suggest that, from the above description, various changes and modifications can be made by the person skilled in the art without departing from the scope of the technical idea of the present invention. The technical scope of the present invention is not limited to the contents of the specification, and the technology must be determined according to the scope of claims.
