[0002] In actual cable laying scenarios, due to the limitations of cable production processes, the complexity of long-distance transportation, and the strict requirements for specific topological structures during the laying process, the cables often cannot maintain continuity, and the effective connection between the two sections of cables must be achieved by installing intermediate joints. As a vital cable accessory, the core function of the high-voltage cable intermediate joint is to ensure the unobstructed power transmission line, while maintaining the sealing inside the cable to ensure that the insulation performance at the joint meets the specified standards, thereby ensuring that the entire high-voltage cable line can operate safely and reliably. Compared with the relative simplicity of the high-voltage cable body structure, the structure of the cable intermediate joint is particularly complex, which undoubtedly increases the difficulty of on-site assembly. During the installation process, construction personnel not only need to have superb skills, but also need to face a harsh working environment. Any minor flaws or improper operation may become a potential weakness in the cable intermediate joint, which will cause serious problems such as insulation breakdown, which will affect the power supply reliability of the high-voltage cable line and may also pose a threat to the stable operation of the entire power system.

Its quality and accuracy have a decisive impact on the power supply reliability of the cable line and the overall performance of the system. In the traditional cable accessories assembly crimping process, it has become normal for construction workers to frequently consult the specific standards and steps of conductor crimping. This behavior has greatly distracted their attention and reduced operational efficiency; what is more difficult is that in order to ensure that the crimping distance and the rubber parts positioning distance strictly meet the established technical standards, the construction workers have to perform multiple tedious measurements, which not only greatly prolongs the construction time, but also increases the risk of errors, posing a considerable challenge to the progress and quality of the entire cable laying project.

DETAILED DESCRIPTION

[0024] Example 1 As described in the background technology, the structure of the cable intermediate joint is complex relative to the high-voltage cable body. During the on-site installation of the cable intermediate joint, the construction personnel's skill level and working environment are required to be high. Any slight defect can form a weak point in the cable intermediate joint, causing insulation breakdown, seriously affecting the power supply reliability of the high-voltage cable line, and even affecting the operation of the entire system. In the crimping process of traditional cable accessory assembly, in addition to frequently checking specific standards such as conductor crimping, construction personnel also need to frequently obtain relevant information of the steps. This behavior will greatly affect the construction personnel's operating efficiency. In addition, during the construction process, in order to ensure that the crimping distance and the rubber part positioning distance meet the standards, the construction personnel need to measure them multiple times, which prolongs the construction time. It can be seen that the existing high-voltage cable accessory assembly crimping and subsequent process construction efficiency is low and the construction quality is low.

[0025] In order to solve the above problems, the present invention provides a guiding method for crimping cable accessories based on augmented reality technology. The method can apply augmented reality technology to the crimping and subsequent processes of the high-voltage cable accessories assembly process, and can provide assembly information for construction personnel without affecting the operation of their hands; after the construction personnel operate multiple steps, laser scanning can be used to facilitate the measurement process, reduce the time required for measurement, and can be reserved as construction inspection data for later inspection; the method can greatly shorten the construction time and improve the construction efficiency. .

[0026] This embodiment provides a method for guiding crimping cable accessories based on augmented reality technology, and the specific steps are as follows: The first step is to use augmented reality technology to capture images of cable accessories during the crimping process in real time and obtain the current assembly status information based on this.

[0027] The second step is to compare the assembly status information with the base body pose estimation data pre-stored in the system to find the best matching record; once a match is found, the system will automatically generate guidance information corresponding to the assembly status. The above guidance information details the specific operation steps, precautions and operating guidelines for crimping cable accessories.

[0028] Step 3: The output guidance information will be sent to a dedicated guidance output device. The guidance output device uses multimedia means, such as video, image or audio, to clearly display the guidance information to the construction personnel. In this embodiment, it should be noted that: when the guidance information indicates that a detection step is required, the system will further obtain three-dimensional information of the cable accessories; by comparing and analyzing these three-dimensional information with reference samples pre-stored in the system, the detection result can be obtained; based on this result, the system will generate corresponding guidance information again to ensure that construction personnel can follow the correct steps and effectively avoid risks such as operational errors and assembly failures.

[0029] In this embodiment, the guidance information not only includes each operation step in the crimping process, but also clearly points out the names of these steps and the corresponding operation guides; these step names cover the entire process from conductor crimping to expansion, pulling out and positioning of rubber parts, wrapping, copper shell installation, lead enamel sealing, glue potting sealing, to grounding.

[0030] In particular, in the guidance information, the guidance of crimping cable accessories based on augmented reality technology also sets a special detection step. When the system recognizes that it needs to perform detection, it will use laser scanning technology to quickly obtain the three-dimensional information of the cable accessories and build a three-dimensional model based on it; then, the three-dimensional model is compared with the reference sample pre-existing in the system, combined with the reference threshold set by the guidance of crimping cable accessories based on augmented reality technology, so that the entire guidance system can accurately determine whether the cable accessories meet the standards.

[0031] In this embodiment, based on the test results, the guidance system will intelligently generate the next step of guidance information; if the test result is in compliance with the standard, the system will automatically generate the operation steps after the test step as guidance information according to the preset operation steps. On the contrary, if the test result is not in compliance with the standard, the system will return to the operation steps before the test step to remind the construction personnel to check and adjust.

[0032] In this embodiment, a multimedia presentation method of guidance information is also designed. Based on augmented reality technology, a special guidance output device is selected to convert the guidance information into multimedia formats such as video, image or audio, and display it to the construction personnel in real time; this intuitive presentation method is not only easy for construction personnel to understand and operate, but also greatly improves construction efficiency.

[0033] In this embodiment, after the construction workers receive the guidance information in multimedia format, they also need to obtain their confirmation instructions to ensure that they have understood and are ready to perform the next step; this confirmation instruction can be implemented through the construction workers' voice or gesture actions. Once the confirmation instruction is received, the system will continue to automatically execute the next step of guidance action.

[0034] The guidance method for crimping cable accessories based on augmented reality technology provided in this embodiment is implemented and applied in the actual construction process of crimping cable accessories. The specific operations are as follows: like Figure 1 As shown in the figure, after the construction workers arrive at the construction site and confirm that they have put on the augmented reality device, they can activate the 3D virtual menu by saying "menu" by voice or pressing the physical button on the augmented reality device. After activating the menu, they can click the "Start Construction" button in the virtual window through gesture operation to officially start construction. They can also operate the menu items in the 3D virtual menu by saying "Start Construction" by voice.

[0035] First, conductor crimping The camera collects images from the site and determines that the cable matrix is ​​in the conductor crimping step, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice.

[0036] Second, detection Take the handheld laser scanning device and make a 3D model of the cable. The 3D model will be uploaded to the database to check whether the sample meets the standard. If the size is qualified, the construction personnel will be prompted to pass, and the next step will be started after the construction personnel confirm. If the size is unqualified, it will be prompted to fail and the unqualified size will be prompted. After re-construction, re-test until it passes the test. After the construction personnel confirm, the next step will be started.

[0037] Third, expansion, pulling out and positioning of rubber parts The camera collects images from the site and determines that the cable matrix is ​​in the expansion, pulling out and positioning steps of the rubber parts, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice.

[0038] Fourth, wrapping The camera collects images of the site and determines that the cable matrix is ​​in the wrapping step, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice.

[0039] Fifth, copper shell installation The camera collects images from the site and determines that the cable matrix is ​​in the copper shell installation step, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice.

[0040] Sixth, lead-enamel sealing The camera collects images from the site and determines that the cable matrix is ​​in the lead-lined sealing step, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice.

[0041] Seventh, glue sealing and grounding The camera collects images from the site and determines that the cable matrix is ​​in the process of sealing and grounding, and then provides corresponding guidance information. After the construction personnel confirm that this step is completed, they can click the "OK" button in the virtual window through gesture operation to proceed to the next step. They can also complete the confirmation operation by saying "OK" through voice. After the construction personnel confirm, the construction is completed.

[0042] In this embodiment, the specific guidance information is shown in Table 1: Table 1 shows the content of the guidance information.

[0043] It can be seen that this embodiment provides a guidance method for crimping cable accessories based on augmented reality technology, which has the following advantages: Firstly, the method acquires the image of the cable accessories in the crimping process in real time based on augmented reality technology, and obtains the detection information of the current assembly state based on it, so as to realize the accurate monitoring of the crimping process. This real-time monitoring method can timely discover problems in the assembly process and ensure the crimping quality. Secondly, the current assembly state detection information is matched with the pre-stored matrix pose estimation offline data information, and the corresponding guidance information is output to provide a detailed operation step guide for the construction personnel. This intelligent guidance method not only improves the construction efficiency, but also reduces the risk of human operation errors. And when the operation step in the guidance information is a detection step, the three-dimensional information of the cable accessories is obtained by laser scanning, and compared with the pre-stored reference sample, so as to accurately determine whether the cable accessories meet the standard. This detection method is not only fast and efficient, but also accurate and reliable, which provides strong support for the guarantee of construction quality; at the same time, this method also designs a multimedia form of guidance information presentation method, converts the guidance information into multimedia format content such as video, image or audio, and displays it to the construction personnel in real time. This intuitive presentation method is convenient for construction personnel to understand and operate, and improves the construction efficiency and quality. Finally, after the multimedia format content is output to the construction personnel, the next step of the guidance action is automatically executed by obtaining the confirmation voice or confirmation gesture of the construction personnel as a receipt instruction. This interactive mode not only enhances the intelligence of the system, but also improves the controllability and safety of the construction process. The use of this method has significant beneficial effects in the guidance process of crimping cable accessories, which not only improves the construction efficiency and quality, but also reduces the operational risks, providing a strong guarantee for the safe production of the power industry.

[0048] At this time, if the output meets the standard result, the next operation step of the detection step in the preset operation step is generated according to the output that meets the standard result, and is output as the guidance information; otherwise, the previous operation step of the detection step in the preset operation step is generated according to the non-standard result, and is output as the guidance information.

[0064] It can be seen that the present invention provides a guidance method for crimping cable accessories based on augmented reality technology, which has the following advantages over the existing fault diagnosis methods: Firstly, this method accurately obtains the occurrence and termination time of the bolt loosening sound signal and subdivides it into frame segments, which provides a high-quality data basis for subsequent analysis and helps to improve the accuracy of diagnosis; secondly, the full-pole model and group delay function are used to analyze the sound signal, which can deeply explore the sound features, especially the spectrum enhancement soundprint features formed by discrete cosine transform, which effectively highlights the key information of the bolt loosening sound and enhances the sensitivity of diagnosis; thirdly, the embedding space based on convolutional neural network is constructed to map the spectrum enhancement soundprint features to the soundprint prototype. This process not only improves the robustness of feature representation, but also simplifies the complexity of fault diagnosis through prototype matching, making the diagnosis process more efficient; finally, by calculating the distance between the soundprint to be diagnosed and the soundprint prototype, and then determining its attribution probability, the quantitative evaluation of fault diagnosis is realized, which provides a scientific basis for the timely discovery and treatment of the loose bolt fault of the high-voltage circuit breaker, and helps to improve the stability and safety of the power system. In summary, this technical solution can realize the guidance of crimping cable accessories based on augmented reality technology when the actual samples are insufficient, and it has significant advantages in improving the accuracy, sensitivity and efficiency of diagnosis, and has important practical application value.
