Description
Technical Field
[0001] This utility model relates to the field of aerospace and electromechanical product assembly technology, and in particular to a device for assessing the quality of cable laying for civil aircraft. Background Technology
[0002] The quality assessment of civil aircraft cable laying is a core guarantee for the safe operation of civil aircraft electrical systems. Its goal is to verify the quality of the cable itself, the laying process and environmental adaptability through scientific testing methods, and to prevent aviation safety hazards caused by cable failures.
[0003] Traditional cable quality assessment devices often rely on fixed equipment or offline analysis methods. Their bulky size and rigid structure make them unsuitable for operation in confined spaces such as engine rooms, preventing real-time on-site testing. Furthermore, existing evaluation methods depend on human experience to set indicator weights, resulting in high subjectivity and a cumbersome, time-consuming assessment process. These shortcomings not only prolong the testing cycle but also risk human error leading to deviations in cable laying parameters (such as insufficient bending radius or excessive slack), potentially causing cable wear, signal interference, and other safety hazards.
[0004] Therefore, it is necessary to design a quality assessment device for civil aircraft cable laying to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation
[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Example: A device for assessing the quality of cable laying for civil aircraft, such as... Figures 1-6As shown, the device includes a housing 1, a base plate 2, a high-resolution camera 3, a switch 5, a display screen 7, a protective observation plate 8, a dust cover 11, a handle 15, a locking block 17, a compression spring 18, and a limit bracket 19. The housing 1 houses a CPU processor and battery. It employs a high-performance CPU processor that supports real-time data processing and algorithm calculations. The processor can quickly analyze data captured by the sensor, instantly generate a 3D model of the cable, and perform quality assessment. The battery built into the housing 1 is a lithium battery, coupled with an efficient power management circuit, ensuring that the device maintains stable performance even after several hours of continuous operation. The bottom of the housing 1 is equipped with... The base plate 2 has a high-resolution camera 3 mounted on one side. This high-resolution camera 3, a RealSense-3D camera, is a high-precision sensor module used to acquire high-density point cloud data of the cable surface. The sensor in the high-resolution camera 3 can acquire data at a rate of thousands of points per second, ensuring comprehensive capture of cable details. The high-resolution camera 3 is protected by a protective cover. A switch 5 is located on the lower left of the housing 1. Several symmetrically arranged heat dissipation holes 6 are provided on both the front and rear sides of the housing 1. A display screen 7, a high-resolution color touchscreen, is embedded in the top of the housing 1 to display the acquired data. The obtained cable images, 3D reconstruction models, and evaluation results are used to view the display screen 7, which typically has a screen size between 5 and 7 inches, making it convenient for users to view detailed information and operate the device. A protective observation plate 8 is connected to the top of the housing 1, directly above the display screen 7. A symmetrical USB port 9 is located on the lower left side of the housing 1, corresponding to the switch 5, and an audio output jack is located near the switch 5. Several connectors are located on the left side of the housing 1, including a monitor power connector, a power input port, a host HDMI connector, a Type-C1 connector, a Type-C2 connector, and a network cable connector. The housing 1 has a USB-2 interface and a USB-3 interface. The USB interface 9 on the lower left of the housing 1 is divided into a Bluetooth receiver interface and a USB-4 interface. A dust cover 11 is hinged to the left side of the housing 1. A handle 15 is concealed and hinged to the bottom of the base plate 2. The bottom of the base plate 2 has symmetrical sliding blocks 17 on both sides corresponding to the handle 15. A compression spring 18 is connected between the block 17 and the bottom interior. The end of the block 17 abuts against the outside of the handle 15 to form a fastening. A limit bracket 19 is set on the side of the base plate 2 away from the high-resolution camera 3. After the handle 15 is rotated to the limit of 180°, its middle part is locked in the limit bracket 19.
[0027] like Figure 1 and Figure 3 As shown, it also includes anti-slip buffer pads 10. Anti-slip buffer pads 10 are connected to each corner of the bottom of the housing 1. The anti-slip buffer pads 10 increase the friction at the bottom of the housing 1 and suppress the interference of vibration on data acquisition.
[0028] like Figure 4As shown, it also includes a toggle block 12 and a torsion spring 14. The bottom of the dust cover 11 is provided with a protruding toggle block 12, and there is an inlet 13 between the inner side of the dust cover 11 and the left end face of the housing 1 for the wire to pass through. The inlet 13 allows external wires to be connected while maintaining dust protection. Torsion springs 14 are connected to both sides of the hinge shaft between the dust cover 11 and the housing 1. The toggle block 12 assists in opening the cover, and the torsion spring 14 automatically resets and closes.
[0029] like Figure 2 As shown, it also includes a fill light 4. The fill light 4 is connected to the inside of the outer protective cover of the high-resolution camera 3. The fill light 4 automatically adjusts its brightness according to the ambient light intensity to ensure that the high-resolution camera 3 can produce clear images in low light.
[0030] like Figure 5 and Figure 6 As shown, it also includes an anti-slip sleeve 16. The outer side of the gripping end of the handle 15 is covered with an anti-slip sleeve 16. The anti-slip sleeve 16 increases the gripping friction of the handle 15 and prevents slipping during operation. It is elastically fixed by silicone material.
[0031] In use, the user holds the handle 15 and, by rotating and shifting the locking block 17, overcomes the resistance of the compression spring 18, rotating the handle 15 from the bottom of the base plate 2 to its 180° limit position, where it engages within the limiting bracket 19, allowing for one-handed grip and operation of the device. Pressing the switch 5 on the lower left of the housing 1 starts the device, and the built-in high-performance CPU processor begins operation, activating various functional modules. After the device starts, the high-resolution color touchscreen on the top inside the housing 1 lights up, displaying the device's initial interface, including areas for device status, parameter settings, and evaluation results. The user can then adjust the high-resolution camera 3 (RealSense-D camera) on one side of the base plate 2 as needed. The angle and position of the camera are carefully selected to ensure it can clearly capture the details of the cable surface. On display screen 7, the cable quality inspection function is selected. The device's high-performance CPU processor begins processing the cable image data captured by the camera in real time. The high-resolution 3RealSense-D camera acquires high-density point cloud data of the cable surface at extremely high speed, ensuring comprehensive capture of cable details. The processor uses advanced algorithms to generate a 3D model of the cable in real time based on the acquired point cloud data. Through analysis of the 3D model, the processor can calculate the cable's geometric features (such as radius, slack, bending radius, etc.) and automatically evaluate the cable's quality, even in low-light conditions. The device automatically activates the supplementary light 4 to provide sufficient light for the camera, ensuring the clarity of the cable image and the accuracy of the detection results. During the detection process, the display screen 7 will display the acquired cable image, 3D reconstruction model, and evaluation results in real time. Users can adjust settings, view detailed information, or export the evaluation report using buttons or sliders on the touchscreen. The device has reserved interfaces such as USB and HDMI, allowing users to connect external storage devices (such as USB flash drives or portable hard drives) or monitors to export detection data or conduct demonstrations. Users can select the data export function on the display screen 7 and choose the data type to export (such as cable image, 3D model, evaluation report). Then, insert the external storage device into the USB port 9 of the device to complete the data export. If you need to display the test results to others, you can connect the monitor to the HDMI port of the device and select the demonstration mode on the display screen 7 to display the test process and results in real time on the display screen. After completing the cable quality test and evaluation, the user presses the switch 5 on the lower left of the housing 1, and the device begins to shut down. The various functional modules gradually stop running. In order to prevent dust and debris from entering the device, the user should close the dust cover 11 after shutting down the device. The torsion springs 14 on both sides of the hinge shaft between the dust cover 11 and the housing 1 will automatically keep the dust cover 11 in the closed state.
