[0025] As described in the background section, existing technologies struggle to detect aging and cracks in the internal structure of substation external insulation materials, such as insulators and post insulators, using conventional methods like infrared detection and partial discharge testing, especially in the absence of abnormal temperatures or discharges. These monitoring deficiencies pose safety hazards. Currently, there is a lack of rapid detection methods for insulation materials during operation; assessments are generally based on indirect methods using laboratory sampling, which are difficult to perform in real-time and lack the accuracy of laser imaging.

[0026] To achieve the above objectives, according to one aspect of this application, such as Figure 1 As shown, an insulator detection system is provided, comprising: a laser generator 10 for emitting a first laser beam to an insulator 20; a photoconductive antenna 30 located between the laser generator 10 and the insulator 20 for converting the first laser beam into a second laser beam, wherein the frequency of the second laser beam is higher than that of the first laser beam; a semi-transparent mirror 40 located between the photoconductive antenna 30 and the insulator 20 for refracting the second laser beam reflected by the insulator 20; and a visualization component 50 for receiving the second laser beam reflected by the insulator 20 refracted by the semi-transparent mirror 40 and converting the information of the reflected second laser beam into a visualization image, wherein the visualization image is used to display the aging degree of the insulator 20.

[0027] The aforementioned insulator detection system uses a laser generator to emit a first laser beam towards the insulator. A photoconductive antenna converts this first laser beam into a second laser beam with a higher frequency. The insulator reflects the second laser beam, and a semi-transparent mirror refracts the reflected second laser beam onto a visualization component. A visualized image of the insulator is obtained based on the reflected second laser beam, and the aging degree information of the insulator is obtained from this image. This detection system can detect the insulator in real time, and the use of high-frequency laser detection technology improves the accuracy of the detection, thus solving the problems of low accuracy and difficulty in real-time detection of insulator aging in existing technologies.

[0028] In the above optional implementations, such as Figure 1 As shown, the visualization component 50 includes a photosensitive sheet, which is a photochromic material that can be fabricated using a 25-layer graphene film (the film material is 95% vanadium dioxide, 4% tungsten, and 1% silver bromide). This film can transmit changes in laser light as changes in visible light, allowing visualization of the image using ordinary photosensitive or photographic methods.

The first laser beam transmitted by the reflector assembly 70 has a time delay. The reflector assembly 70 includes a first reflector 71 and a second reflector 72. The laser beam is transmitted sequentially through the first reflector 71 and the second reflector 72 to the coherent detector 80. The coherent detector 80 compares the coherence of the signal of the second laser beam with incident time delay and insulator reflection, and feeds the comparison result back to the laser generator 10 so that the laser generator 10 can adjust the appropriate emission frequency and intensity of the first laser beam to achieve the best detection effect.

The photoconductive antenna 30 converts the first laser into a second laser, and the frequency of the second laser is higher than that of the first laser.

[0039] In step S202, the photoconductive antenna 30 is controlled to emit the adjusted second laser to the insulator 20. The insulator 20 reflects the second laser to the semi-transparent lens 40 of the detection system. The semi-transparent lens 40 refracts the second laser reflected by the insulator 20 to the visualization component 50, so as to convert the information of the reflected second laser into a visual image. The visual image is used to display the aging degree of the insulator 20.

[0040] The aforementioned insulator detection method involves controlling a laser generator to emit a first laser beam towards the insulator. A photoconductive antenna converts the first laser beam into a second laser beam with a higher frequency. The photoconductive antenna then emits the second laser beam towards the insulator, which reflects the second laser beam. A semi-transparent mirror refracts the reflected second laser beam onto a visualization component. A visualized image of the insulator is obtained based on the reflected second laser beam, and the aging degree information of the insulator is obtained from the visualized image. This detection system can detect the insulator in real time, and the use of high-frequency laser detection technology improves the accuracy of the detection, thus solving the problems of low accuracy and difficulty in real-time detection of insulator aging in existing technologies.

[0041] In some alternative implementations, controlling the laser generator of the detection system to emit a first laser to the photoconductive antenna of the detection system includes: controlling the laser generator to emit the first laser to the beam splitter of the detection system, so that the beam splitter transmits a portion of the first laser to the photoconductive antenna and another portion of the first laser to the reflector assembly of the detection system, and the reflector assembly transmits the first laser to the coherent detector of the detection system.

[0042] In the above optional embodiments, after the laser generator emits the first laser, the beam splitter refracts the first laser onto the reflector assembly. The first laser transmitted by the reflector assembly has a time delay. The coherent detector compares the coherence of the signal of the second laser with incident time delay and insulator reflection, and feeds the comparison result back to the laser generator so that the laser generator can adjust the appropriate emission frequency and intensity of the first laser to achieve the best detection effect.

The spectral feature information includes local aging information of the insulator, and all aging information of the insulator can be obtained according to the plurality of spectral feature information.

[0045] In some optional embodiments, obtaining a plurality of spectral feature data of the visualization image according to the visualization image includes: obtaining a plurality of the spectral feature data according to a first formula, where the first formula is: y = a n x n + a n- 1x n-1 +... a0, where x is the pixel position of the visualization image, y is the gray-scale data of the corresponding pixel position, n is the fitting order, and a n is the plurality of spectral feature data of the visualization image.

[0046] In the above optional embodiment, according to y = a n x n + a n-1 x n-1 +... a0, polynomial fitting is performed to obtain a gray-scale - aggregation degree image relationship curve of the spectral slice of the laser, where x is the pixel position of the image, y is the gray-scale data of the corresponding position, n is the fitting order, and a n is the spectral feature data obtained through the fitting algorithm. The coefficient vector A[an, an-1,..., a0] is obtained after fitting. If the number of pixel points is 300×300 = 90,000, the fitting order n can be taken as 6. For the convenience of convergence, n generally takes 6 - 8. The same imaging analysis is performed on a brand-new insulator of the same type to obtain the coefficient vector A0, and the aging degree of the detected insulator can be expressed by the formula:
