Description

Technical Field

[0001] This invention relates to the field of error prevention and testing technology for aviation equipment cable plugs, specifically to a device for error prevention and testing of aviation equipment cable plugs. The application of this device can effectively prevent incorrect insertion of aviation equipment cable plugs, which could cause damage to the cable plugs and improve the reliability of cable plug testing. Background Technology

[0002] Before leaving the factory, aviation equipment cables must undergo continuity tests, radio frequency (RF) tests, and insertion loss tests. Inserting the cable plug into the wrong socket before these tests can damage the plug and even cause these tests to fail, severely impacting production schedules. Currently, plug selection before these tests is done manually. Because plugs for various aviation equipment cable models are visually similar, testers easily become confused when selecting plugs and sockets, leading to mismatches and damage to the pins. This can cause cables that appear normal in all tests to be misidentified as being in an abnormal state, resulting in inaccurate test results and the misuse of cables. This reduces operator reliability, increases the risk of errors and omissions by inspectors, and decreases efficiency. Summary of the Invention

[0003] To address this issue, a device for error prevention in the inspection of cable plugs for aviation equipment has been invented. This device utilizes deep learning algorithms to intelligently identify the model of the cable plug and provides light prompts for the corresponding socket to be inserted. This effectively prevents inconsistencies between the cable plug and the socket, thus resolving test failures caused by such inconsistencies. It effectively prevents plug errors, and the use of artificial intelligence to replace manual labor greatly improves inspection efficiency and reliability while reducing workload.

[0004] The technical problem solved by this invention is achieved by the following technical solution:

[0005] In this invention, a special identification mark is set on the surface of the cable. Before the cable under test is inserted into the cable detection socket, the special mark is identified by a smart camera. The collected special mark data is transmitted to the edge computing module for calculation. The edge computing module can receive and calculate the data transmitted by the data acquisition module. After the calculation is completed, the mark data is transmitted to the microcontroller. The microcontroller transmits further instruction information to the controller. The controller reacts and controls the light alarm next to the cable socket to light up green. To prevent detection errors, the cable under test is inserted into the lit cable socket. If the light alarm changes from green to red after insertion and the buzzer sounds an alarm, it indicates that the cable is inserted into the cable socket incorrectly. The cable needs to be pulled out of the cable socket and the insertion position of the cable needs to be changed to avoid the cable plug being inserted in the wrong position.

[0006] According to one aspect of this application, a device for detecting and preventing errors in cable plugs of aviation equipment is provided, comprising a mechanical connection component structure and a detection and control component structure;

[0007] The mechanical connection component structure consists of a clamping body 1, a connecting rod 2, a double-ended stud 3, a steering body 4, a pressing body 5, a pressing rod 6, a ball joint rod 7, a ball joint seat 8, a connecting screw 10, a main housing 11, an upper housing 12, a camera connector 18, a washer 19, a hexagonal nut 20, a bolt 21, a stud with a hole 25, and a flexible connector 26.

[0008] The detection and control component consists of a buzzer 9, a display screen 13, a cable socket 14, a USB port 15, a charging port 16, a switch button 17, an HTTP interface 22, an HDMI interface 23, a recording button 24, a camera 27, a microcontroller 28, a controller 29, an edge computing module 30, a data acquisition module 31, a light alarm 32, and a test board 33.

[0009] The clamping body 1 is the main load-bearing component. The steering body 4, the clamping body 5, and the clamping rod 6 work together to lock the clamping body 1 onto the cable plug error prevention test bench, providing stable support for the entire device.

[0010] The connecting rod 2 is a connecting component with threaded structures at both ends. One end is fixedly connected to the outer wall of the clamping body 1 through an external thread, and the other end is connected to the double-ended stud 3 through an internal thread, thus serving to connect the clamping body 1 with the device.

[0011] The double-ended stud 3 is a connecting component. Both ends of the double-ended stud 3 are externally threaded. The left end is connected to the connecting rod 2 through the external thread, and the right end is connected to the ball joint rod 7 through the external thread. The double-ended stud 3 can be conveniently connected by the external thread and plays a connecting role.

[0012] The steering body 4, the clamping body 5, and the clamping rod 6 are the main clamping structure components;

[0013] The steering body 4 is interference-fitted with the clamping rod 6, which can drive the clamping rod 6 to rotate together with the steering body 4;

[0014] The right end of the clamping body 5 is connected to the clamping rod 6 by a ball joint. The ball joint connection allows the clamping body 5 to swing freely and adjust its direction to press it onto the experimental table in different directions, so as to press it more tightly.

[0015] The clamping rod 6 has an external thread and is connected to the clamping body 1 through the external thread, which can easily drive the clamping body 5 to move and complete the fixing function;

[0016] The steering body 4 is fixedly connected to the clamping rod 6. Rotating the steering body 4 can drive the clamping rod to rotate, making it easier to rotate the clamping rod 6.

[0017] The ball joint rod 7 is the main steering component. The ball joint rod 7 is fixed to the clamping body 1 by means of the stud away from the double-ended stud 3. The end of the ball joint rod 7 is hinged to the inside of the ball joint seat 8, so that the ball joint seat 8 and its connected components can rotate as needed.

[0018] The ball joint seat 8 is the main moving component. The ball joint seat 8 can be installed on the main housing 11 using the connecting screw 10. The ball joint seat 8 and the ball joint rod 7 can make the main housing 11 easily rotate and adjust its direction.

[0019] The connecting screw 10 is the main connecting component of this invention. The connecting screw 10 can connect the ball joint seat 8 and the main housing 11, thereby transmitting the movement of the ball joint seat 8 to the main housing 11 and realizing the rotation function of the main housing 11.

[0020] The upper housing 12 is a closed component, which is installed on the upper end of the main housing 11 by screws, thereby closing the main housing 11 and preventing foreign objects from entering it.

[0021] The camera connector 18 is a display connection component. It is installed at the bottom of the main housing 11 using hexagonal nuts 20 and bolts 21, and serves to connect the main housing 11 and the flexible connector 26.

[0022] The washer 19, hexagonal nut 20, and bolt 21 are the main fixing components for the camera connection. The washer 19, hexagonal nut 20, and bolt 21 are used to firmly fix the camera connector 18 to the main housing 11. The washer 19 increases the contact area and reduces the pressure. By increasing the contact area between the bolt 21 and the object, the force is reduced, preventing loosening due to small contact area, and making the connection between the camera connector 18 and the main housing 11 more secure.

[0023] The perforated stud 25 is a signal transmission connection component. Its hollow structure facilitates the transmission of video image signals from the camera 27 to the signal processing component. The camera device is fixed to the main housing 11 through a threaded connection. The flexible connector 26 is a focus adjustment component. The flexible connector 26 can be used to adaptively adjust the position of the camera 27, thereby achieving adaptive adjustment of the video image clarity and facilitating the camera 27 to capture markings on the cable.

[0024] The buzzer 9 can emit sound to indicate an error, and the light alarm 32 can flash a red or green light to indicate an error. The buzzer 9 and the light alarm 32 are installed on the test board 33. When the cable is connected incorrectly during the test, the light alarm 32 will flash a red light to indicate an error. When the light alarm 32 flashes a green light during the test, it indicates that the cable is installed correctly.

[0025] The display screen 13 is a test result display component, which is set on the upper surface of the main housing 11. The display screen 13 is used to display test data and display signals, so that the inspection personnel can operate according to the data displayed on the display screen 13.

[0026] The cable socket 14 is a test connection component, which is opened on the test plate 33 and overlaps with the socket on the test bench. During the cable plug test, the cable is inserted into the cable socket 14 for plug test.

[0027] The U-port 15 is an extension component, which is fixedly installed at the front end of the main housing 11. The U-port 15 can be used to connect external camera equipment to extend the function of the test position or to meet higher-level camera acquisition performance requirements.

[0028] The charging port 16 is a charging connection component, fixed to the front end of the main housing 11. The charging port 16 facilitates charging of the power module and provides sufficient power.

[0029] The switch button 17 is a start / stop button, which controls the start and stop functions of the entire device;

[0030] The HTTP interface 22 is an algorithm access component, which is fixedly connected to the rear end of the main shell 11. The HTTP interface 22 can import recognition algorithms and can be used to connect to a computer for programming interaction, achieving various connection input purposes.

[0031] The HDMI interface 23 is an extended display connection component, which is fixedly connected to the rear end of the main housing 11. The HDMI interface 23 supports the transmission of video and audio signals and can send uncompressed audio and video signals at the same time. The HDMI interface 23 makes the transmission of high-definition audio and video signals more efficient and convenient, and can extend display devices, such as connecting to a large screen monitor.

[0032] The recording button 24 is the main operating component, fixed to the front end of the main housing 11. The recording button 24 can record and save the data after the device is monitored, which facilitates the use of the device data.

[0033] The camera 27 is a video data acquisition component, fixed on the flexible connector 26. The flexible connector 26 can be used to adaptively adjust the position of the camera 27, making it convenient for the camera 27 to capture the markings on the cable.

[0034] The microcontroller 28 is the core processing component. It is installed inside the main housing 11 by screws. The microcontroller 28 can transmit the control command information calculated by the edge computing module 30 to the controller 29, so as to control the controller 29 and drive the entire device.

[0035] The controller 29 is the core control component. It is installed inside the main housing 11 by screws. The controller 29 can control the light alarm 32 next to the cable socket 14 to light up and the buzzer 9 to sound.

[0036] The edge computing module 30 is the core component for detecting data processing. It is installed inside the main housing 11 by screws. The edge computing module 30 can receive and process the data transmitted by the data acquisition module 31, and then transmit the processed data to the microcontroller 28.

[0037] The data acquisition module 31 is the core data acquisition component. It can collect data signals from the camera 27 that are marked on the cable, and then transmit the collected data to the edge computing module 30 for processing. The microcontroller 28, controller 29, edge computing module 30, and data acquisition module 31 can process the signals captured and identified by the camera 27. This process involves the data acquisition module 31 collecting data signals from the camera 27 that are marked on the cable, transmitting the collected data to the edge computing module 30 for processing, and the edge computing module 30 processing the data signals captured by the data acquisition module 31. The transmitted data is received and processed. After the processing is complete, the data is transmitted to the microcontroller 28. The microcontroller 28 controls the controller 29 to light up the light alarm 32 at the corresponding position of the cable socket 14, turning it green. The cable to be tested is then inserted into this position. The controller 29 controls the light alarm 32 and the buzzer 9 next to the cable socket 14 to activate. If the green light remains unchanged, it means that the cable is inserted into the cable socket 14 correctly. If the controller 29 controls the light alarm 32 next to the cable socket 14 to change from green to red and the buzzer 9 sounds an alarm, it means that the cable is inserted into the cable socket 14 incorrectly.

[0038] The advantages of this application are:

[0039] Analysis of existing cable plug error prevention methods reveals that plug selection before testing requires manual intervention. Since the appearance of cable plugs for various types of aviation equipment is largely identical, testers are prone to confusion when selecting plugs and sockets, leading to mismatches and damage to the pins. Consequently, cables that appear normal and intact during testing may not be correctly identified as being in good working order when inserted into the cable socket, resulting in inaccurate test results and the misuse of cables with valid test conditions. This leads to low operator reliability, increased risk of errors and omissions by inspectors, and reduced efficiency.

[0040] To address and avoid the aforementioned problems, this invention provides a convenient cable plug detection and error prevention device for aviation equipment. This device achieves intelligent detection of cable plugs, reducing human error in judging cable plugs. Simultaneously, a camera captures and identifies special model markings on the cable surface. A data acquisition module then collects the data signals from these markings, and a microcontroller transmits the information to a controller. The controller responds by illuminating a light alarm next to the cable connector, with indicator lights displaying different states to provide feedback. This prevents the cable plug from being inserted incorrectly. Furthermore, artificial intelligence significantly improves detection efficiency and reliability while reducing workload.

This process involves the data acquisition module 31 collecting data signals from the camera 27 that are marked on the cable, transmitting the collected data to the edge computing module 30 for processing, and the edge computing module 30 processing the data signals captured by the data acquisition module 31. The transmitted data is received and processed. After the processing is complete, the data is transmitted to the microcontroller 28.

The cable to be tested is then inserted into this position. The controller 29 controls the light alarm 32 and the buzzer 9 next to the cable socket 14 to activate. If the green light remains unchanged, it means that the cable is inserted into the cable socket 14 correctly. If the controller 29 controls the light alarm 32 next to the cable socket 14 to change from green to red and the buzzer 9 sounds an alarm, it means that the cable is inserted into the cable socket 14 incorrectly.

[0081] The specific work process is as follows:

[0082] Step 1: Before use, perform a visual inspection of the error-proofing device, check whether the device label is complete and whether the appearance is intact. If it is complete and intact, proceed to the next step.

[0084] Step 3: Press switch button 17 to turn on the error prevention device, check the continuity of the error prevention device circuit, and ensure that the detection device is functioning properly;

[0085] Step 4: Place the cable to be tested under the camera 27 to collect image data. The flexible connector 26 can automatically control the camera 27 to collect data. After the image data is collected, the corresponding position of the light alarm 32 on the test board 33 will turn on a green light to indicate the position of the test channel.

[0086] Step 5: Insert the cable to be tested into the cable socket 14 on the test board 33 shown in Step 4 to complete the cable testing connection;

[0087] Step Six: If the green light of the light alarm 32 does not change to red and the buzzer 9 does not sound, it proves that the cable plug and the socket are matched one by one. Press the record button 24 to record the test result. If the green light of the light alarm 32 changes to red and the buzzer 9 sounds, it proves that the cable plug and the socket are not matched. Press the record button 24 to record the test result. Repeat Step Four to perform the plug error prevention test again.

[0088] Step 7: After testing all the cables in sequence, press switch button 17 to turn off the power to the entire test device.
