Description

Technical Field

[0001] The present invention relates to the field of aviation, and in particular to a management system for aviation maintenance tools. Background Art

[0002] Aviation maintenance involves a vast array of tools, making their use and management complex. The current tool lending process is as follows: After receiving a work order, maintenance personnel proceed to the tool warehouse to collect necessary items, including general tools, specialized tools, and consumables. A front desk manager in the tool warehouse confiscates the maintenance personnel's work ID and then lends the tools required by the work order. The maintenance personnel then proceed to the hangar to perform aircraft maintenance. After completing the work, the maintenance personnel personally count and verify that all tools are complete, return them to the tool warehouse, and retrieve their work ID, completing the work order.

[0003] This process currently has several drawbacks: When picking up and returning tools, administrators must manually allocate and verify them based on work orders, which is time-consuming. During peak hours, tool collection requires queuing, hindering maintenance efficiency. Tools require regular inspection to ensure accuracy, and current warehouse management requires manual checking of tool expiration dates, which is inefficient.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Summary of the Invention

If it does not need to be repaired, the robotic arm will put it back to the corresponding storage location. If it needs to be repaired, the robotic arm will place it in the maintenance area of the warehouse. This system directly conducts verification during the process of returning maintenance tools, eliminating the need for staff to regularly check, and effectively improving the management efficiency of maintenance tools.

[0035] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] A management system for aviation maintenance tools includes maintenance work orders, a control platform, a robotic arm, an outbound mechanism, an inbound mechanism, and a transport track.

[0037] In this example, the warehouse for storing maintenance tools is divided into different storage areas according to the performance of the maintenance tools, such as a consumables area, a general tool area, and a special tool area, and a maintenance area for storing maintenance tools that need to be maintained is provided.

[0038] The control platform is communicatively connected to the transport track. The transport track is used to transport maintenance tools out of the warehouse and back to the warehouse. The transport track has multiple outlet ends and multiple inlet ends. In this embodiment, the transport track includes an outbound track and a return track, and a part of the outbound track and a part of the return track are arranged vertically to save operating space. When the maintenance tool is placed on the outbound track, the control platform will control the outbound track to transport the maintenance tool to the corresponding outlet end. When the maintenance tool is placed on the return track, the control platform will control the return track to transport the maintenance tool to the corresponding storage or maintenance area.

[0039] The transport track in this embodiment is a conventional transport track, and a Qingyue Starlight flexible chain conveyor, a flat-top chain conveyor, or a turning chain conveyor belt can be used.

[0040] The maintenance work order has QR code information. In this embodiment, the maintenance work order is determined by the maintenance personnel through a meeting discussion according to the maintenance content before the start of the daily aviation maintenance task. The maintenance work order has information such as maintenance tasks, maintenance tool lists, and aircraft models. The specific information on the maintenance work order can be set according to the system and the actual maintenance work requirements.

[0041] The outbound mechanism includes at least one outbound device, such as Figure 1 As shown, each outbound device includes an outbound workbench 11 and a first conveying mechanism. The inlet ends of each first conveying mechanism are respectively connected to the outlet ends of each transport track in a one-to-one correspondence.

[0042] Each first conveying mechanism is used to transport the maintenance tools on the transport track to the outlet end of the first conveying mechanism.

[0043] Each first conveying mechanism includes a first storage table 12 and a first track 13. The first storage table 12 is located on one side of the corresponding outbound workbench 11, and the first track 13 is located on the side of the first storage table 12 away from the outbound workbench 11. In this embodiment, the outbound workbench 11, the first storage table 12, and the first track 13 are all separate devices, arranged close to each other in sequence, and there is no connection between the devices, which is convenient for maintenance and replacement, and there is no need to replace all devices because one of the devices is damaged.

[0044] At the exit end of the first crawler 13, there is a first baffle 131. A pressure sensing device for triggering the first crawler 13 to stop rolling is provided on the first baffle 131. At the entrance end of the first crawler 13, there is a first infrared sensing device for triggering the first crawler 13 to roll. The entrance end of the first crawler 13 is connected to an exit end of the outgoing crawler. The first crawler 13 in this embodiment is a conventional ball crawler, and the Shanghai Guanpeng Machinery Logistics Sorting 400 Ball Universal Conveyor Network can be used. Here, the connection means that the exit end of the outgoing crawler is connected to the entrance end of the first crawler 13, and the rolling speed of the outgoing crawler is greater than that of the first crawler 13. The maintenance tool is conveyed onto the first crawler 13 under the drive of the outgoing crawler; the pressure sensing device and the first infrared sensing device are respectively communicatively connected to the first crawler 13.

[0045] When the maintenance tool is conveyed to the entrance end of the first crawler 13, since the maintenance tool blocks the infrared rays of the first infrared sensing device, the first infrared sensing device sends information to trigger the first crawler 13 to roll. When the maintenance tool abuts against the first baffle 131, the pressure sensing device senses the pressure and sends information to trigger the first crawler 13 to stop rolling. When the first crawler 13 is triggered to roll again, another maintenance tool can abut against the first baffle 131 or against the previous maintenance tool that has not been taken away yet, and the pressure sensing device can trigger the first crawler 13 to stop rolling when it senses the pressure.

[0046] The pressure sensing device and the first infrared sensing device in this embodiment are both conventional sensing devices. The pressure sensing device in this embodiment can adopt the Luojia FSR402 resistive flexible film pressure sensor force-sensitive RFP602 weighing induction module. The first infrared sensing device in this embodiment can adopt the WWEIGUO infrared diffuse reflection induction photoelectric switch sensor E3Z-D61D62 normally open normally closed DC inductor.

[0047] NFC tags and RFID tags are fixed to each maintenance tool with cable ties.

[0048] The robotic arm is used to obtain or store maintenance tools. The robotic arm is communicatively connected to the control platform. The robotic arm can receive the maintenance tool list sent by the control platform to pick up maintenance tools and place them on the corresponding outgoing crawler, or can also be used to put the maintenance tools on the returning crawler back to the corresponding storage location or place them in the maintenance area. When the robotic arm stores maintenance tools, it identifies and confirms the storage location of the maintenance tool according to the RFID tag on the maintenance tool. The robotic arm in this embodiment is a conventional robotic arm, and the WHEELTEC Lebai LM3 six-axis collaborative robotic arm robot arm can be used.

[0049] Each of the outbound workbenches 11 is equipped with a first barcode scanning end 111, and each outbound workbench 11 is respectively communicatively connected to the control platform; the first barcode scanning end 111 of the outbound workbench 11 obtains the list of maintenance tools on the maintenance work order by scanning the QR code information on the maintenance work order.

[0050] The first barcode scanning end 111 is used to scan the QR code information to obtain the list of maintenance tools on the maintenance work order. The outbound workbench 11 sends the obtained list of maintenance tools to the control platform, and the control platform sends the list of maintenance tools to the robotic arm in the corresponding area. The robotic arm obtains the corresponding maintenance tools according to the list of maintenance tools and places the maintenance tools on the outbound conveyor belt, and the control platform manipulates the outbound conveyor belt to convey the maintenance tools to the corresponding first conveyor belt 13.

[0051] The control platform in this embodiment is a conventional control chip, and the RS-485 / RS-422 chip SP3485EENUMW (YouTai Semiconductor) can be used.

[0052] As Figure 2 shown, the warehousing mechanism includes at least one warehousing device 20. Each warehousing device 20 includes a warehousing workbench and a second conveying mechanism. The outlet ends of the second conveying mechanisms are respectively in one-to-one correspondence and connection with the inlet ends of the transport conveyor belts. Each second conveying mechanism is used to convey the maintenance tools to the return conveyor belt. Each second conveying mechanism includes a second placement table and a second conveyor belt 21. In this embodiment, the outlet ends of the second conveyor belts 21 are respectively in one-to-one correspondence and connection with the inlet ends of the return conveyor belts. The second conveyor belt 21 and the first conveyor belt 13 adopt the same ball conveyor belt.

[0053] In this embodiment, the warehousing workbench, the second placement table and the second conveyor belt 21 are arranged close to each other in sequence, and there is no connection between the devices, which is convenient for maintenance and replacement, and there is no need to replace all devices because one of the devices is damaged.

[0054] A detection channel (not shown in the figure) is provided on each second conveying mechanism, and the detection channel is located at the inlet end of the second conveyor belt 21.

[0055] A camera device is provided on each detection channel, and each camera device is respectively communicatively connected to the control platform. Pictures of each maintenance tool are stored on the control platform. Each warehousing workbench is respectively communicatively connected to the control platform. After confirming the maintenance tool list, the warehousing workbench sends an instruction to the control platform, and the control platform calls out the pictures of the maintenance tools on the maintenance tool list for comparison with the photos transmitted back by the detection channel.

[0056] In this embodiment, each camera device includes a first camera, a second camera and a third camera.

[0057] The first camera is fixed directly above the second crawler corresponding to the detection channel through a frame, and is used to obtain a top view of the maintenance tool; the second camera and the third camera are respectively fixed on both sides of the second crawler 21 corresponding to the detection channel, and the second camera and the corresponding third camera are arranged opposite to each other, and are used to obtain a side view of the maintenance tool. Each of the first camera, the second camera and the third camera is communicatively connected to the control platform, and is used to transmit the captured photos back to the control platform. By setting three cameras to obtain the three views of the maintenance tool for comparison, it is possible to better confirm whether the maintenance tool needs to be maintained.

[0058] The first camera, the second camera and the third camera in this embodiment are all conventional cameras. The Huaxing Video G1E4 camera can be used, or other conventional cameras can be selected according to the comparison requirements.

[0059] As Figures 3 - 5 shown, the management system of this embodiment further includes smart glasses 30, a smart toolbox 40 and smart gloves 50.

[0060] On the side of the smart glasses 30 facing the eyes, there is an iris recognizer. On the side of the smart glasses 30 away from the eyes, there is a fourth camera. The smart glasses 30 are communicatively connected to the control platform, and the smart toolbox 40 is communicatively connected to the control platform and the smart glasses 30 respectively.

[0061] The smart glasses 30 in this embodiment are conventional smart glasses, and the OPPO Air Glass smart glasses can be used. The fourth camera is a conventional camera, and the Huaxing Video G1A0 (IMX377 wide-angle distortion-free module + v39) camera can be used.

[0062] The iris recognizer of the smart glasses 30 in this embodiment is used for identity authentication, and the fourth camera is used to photograph the maintenance process.

[0063] On the inner top surface of the smart toolbox 40, there is a first touch screen 41. The first touch screen 41 is communicatively connected to the smart glasses 30 and the control platform respectively. There are two first NFC signal receivers and a first NFC signal generator on the smart toolbox 40. In this embodiment of the smart toolbox 40, there is also a first analog-to-digital conversion chip for converting analog signal information into digital signal information. The first NFC signal receiver and the first NFC signal generator are respectively communicatively connected to the first analog-to-digital conversion chip, and the first analog-to-digital conversion chip is communicatively connected to the first touch screen.

[0064] The first touch screen 41 in this embodiment is a conventional touch screen, and the Oureko 7-inch TFT liquid crystal display screen, model ORC-T070036N-V01, can be used.

[0065] The intelligent toolbox 40 of this embodiment includes a lid 42 rotatably connected to the intelligent toolbox 40 by a hinge. The intelligent toolbox 40 has a cavity for placing maintenance tools. The first touch screen 41 is fixed on the side of the lid 42 facing the cavity. Two first NFC signal receivers are respectively arranged on two sides of the intelligent toolbox 40 in one-to-one correspondence. The first NFC signal generator is arranged on the front of the intelligent toolbox 40. By setting two first NFC signal receivers and one first NFC signal generator, three-point signal matching of the NFC tag on the maintenance tool is realized. The intelligent toolbox 40 obtains the information of the maintenance tool through the three-point signal matching between the NFC tag on the maintenance tool and the intelligent toolbox 40, and sends and displays the information of the maintenance tool on the first touch screen 41 through the first analog-to-digital conversion chip.

[0066] The intelligent toolbox 40 of this embodiment is used to place maintenance tools, which is convenient for carrying maintenance tools.

[0067] When completing the maintenance task and collecting the maintenance tools, if it is found that the maintenance tools need to be maintained, operations can be performed on the first touch screen 41. The first touch screen 41 sends the maintenance information to the control platform, and the control platform will automatically discard the photo of the maintenance tool transmitted back by the detection channel according to the received maintenance information, that is, there is no need to perform photo comparison, and the maintenance tool is directly transmitted to the maintenance area.

[0068] The intelligent glove 50 has a back surface 51 corresponding to the back of the human hand, and the intelligent glove has a palm surface corresponding to the palm of the human hand. The first display screen 52 is fixedly pasted on the back surface 51. A second NFC signal generator and a first RFID signal generator are arranged on the back surface 51 corresponding to the wrist. A third NFC signal generator and a first signal receiver for receiving NFC and RFID signals are arranged on the palm surface. The first display screen 52 is communicatively connected to the intelligent glasses 30, and the fourth camera is communicatively connected to the first display screen 52. During the maintenance process, the maintenance screen can be transmitted to the first display screen 52 for display, which is more convenient for maintenance personnel to view the maintenance situation.

[0069] In this embodiment, the intelligent glove 50 is also provided with a second analog-to-digital conversion chip for converting analog signal information into digital signal information. The second NFC signal generator and the third NFC signal generator are respectively communicatively connected to the second analog-to-digital conversion chip, and the second analog-to-digital conversion chip is communicatively connected to the first display screen 52, so that when grasping the maintenance tool, the information of the maintenance tool can be displayed on the first display screen 52 to help maintenance personnel better use the maintenance tool.

[0070] The first analog-to-digital conversion chip and the second analog-to-digital conversion chip of this embodiment are both conventional analog-to-digital conversion chips.

[0071] The first display screen 52 in this embodiment is a conventional display screen, and a TFT color screen LCD module display screen module can be used, with the model number ILI9341.

[0072] The first NFC signal generator, the second NFC signal generator, the third NFC signal generator, and the first RFID signal generator in this embodiment are conventional signal generators, and an SI4021 - A1 - FTR RFID radio frequency transmitter can be used.

[0073] The first signal receiver in this embodiment is a conventional signal receiver, and a JRDRFID ceramic ultra - high - frequency reader - writer UHF electronic tag identification tag reading receiver can be used.

[0074] The intelligent glove 50 in this embodiment is used to find missing maintenance tools and prevent them from being lost; first, it enters the RFID mode through the first signal receiver for range positioning, that is, it performs echo positioning through the first signal receiver. After entering the search range of 3 meters, the first signal receiver is switched to the NFC three - point positioning mode, and the second NFC signal generator, the third NFC signal generator, and the first signal receiver on the intelligent glove 50 are used for three - point positioning, which can quickly locate the position of the maintenance tool and help quickly find the lost tool.

[0075] First of all, it should be stated that protective glasses and gloves are required during aircraft maintenance itself. Therefore, the wearing of the intelligent glasses and intelligent gloves of this system does not affect the operation of aircraft maintenance.

[0076] The working process of this management system is as follows:

[0077] 1. The maintenance personnel obtain the maintenance work order, wear the intelligent glasses 30 and the intelligent gloves 50, and obtain the intelligent toolbox 40;

[0078] 2. The intelligent glasses 30 perform identity authentication on the maintenance personnel through iris recognition and send an opening signal to the intelligent toolbox 40 to turn on the first touch screen 41 on the intelligent toolbox 40;

[0079] 3. Place the intelligent toolbox 40 on the first storage table 12. Scan the QR code information of the maintenance work order on the outbound workbench 11. The outbound workbench 11 obtains the maintenance tool list through the QR code information and sends the maintenance tool list to the control platform. The control platform assigns it to the corresponding robotic arm. The robotic arm picks up the tools in the warehouse and places the maintenance tools at the entrance end of the corresponding outgoing track. The control platform controls the outgoing track to convey the maintenance tools to the corresponding exit end. The exit end of the outgoing track conveys the maintenance tools to the first track 13. The infrared ray emitted by the first infrared sensing device is blocked by the first maintenance tool, triggering the first track 13 to roll and transporting the maintenance tool to the first baffle 131. The first maintenance tool abuts against the first baffle 131 to trigger the pressure sensing device to send a stop rolling instruction to the first track 13. When another maintenance tool is conveyed to the entrance of the first track 13, the first track 13 will be triggered to roll again. When the second maintenance tool abuts against the first maintenance tool or against the first baffle 131, it jointly triggers the pressure sensing device to stop the first track 13 from rolling, and so on until the conveyance of the last maintenance tool on the maintenance work order is completed;

[0080] 4. When the first track 13 is conveying the maintenance tools, the maintenance personnel can pick up the maintenance tools on the first track 13 in sequence, bring the NFC tag on the maintenance tool close to the first NFC signal generator of the intelligent toolbox 40 for induction, and achieve three-point positioning and obtain the information of the maintenance tool through two first NFC signal receivers, and display the information of the maintenance tool on the display page of the first touch screen 41. After all the maintenance tools on the maintenance list are placed in the intelligent toolbox 40, the first touch screen 41 will display the maintenance tool list and prompt that all the maintenance tools have been received into the intelligent toolbox 40;

[0081] When the maintenance personnel need to borrow and lend maintenance tools from each other, the lender takes out the maintenance tool from the intelligent toolbox 40. The borrower performs three-point positioning on the maintenance tool in his own intelligent toolbox 40 to obtain the information of the maintenance tool. The first touch screen 41 of the borrower's intelligent toolbox 40 will display from which maintenance personnel the maintenance tool is borrowed, and send the information of the maintenance tool to the control platform. The control platform will record the lending information of the maintenance tool; when the borrower finishes using the maintenance tool, the lender takes the maintenance tool 40 back into his own intelligent toolbox 40 for three-point positioning to obtain the information of the maintenance tool, and sends the information of the maintenance tool to the control platform, and the control platform will delete the lending information of the maintenance tool; to avoid the loss of maintenance tools during the process of borrowing and lending maintenance tools among the maintenance personnel;

[0082] 5. During the maintenance process, maintenance personnel can transmit video signals through the fourth camera on the smart glasses 30, which can be displayed on the first display screen 52 of the smart gloves 50, or the video footage can be transmitted to the smart gloves 50 of other maintenance personnel.

[0083] 6. When returning the maintenance tools, the maintenance personnel place the smart toolbox 40 on the second storage table, then call up their maintenance tool list on the warehousing workbench and confirm it. Then, the maintenance tools are taken out from the smart toolbox 40 in sequence and placed at the entrance end of the second crawler 21. The first camera, the second camera, and the third camera simultaneously take pictures of the maintenance tools and transmit the photos to the control platform. The second crawler 21 conveys the maintenance tools to the return crawler. The control platform compares the three-view drawings transmitted back by the imaging device with the pictures of the corresponding maintenance tools stored in the control platform. If the maintenance tools are in good condition, they are placed in the corresponding storage positions by the robotic arm; otherwise, the return crawler conveys the maintenance tools to the maintenance area.

[0084] In summary, compared with the traditional manual inventory of maintenance tools and the lending and returning of maintenance tools, this management system effectively improves the efficiency of maintenance tool management. At the same time, when the maintenance tools are returned, they are judged based on the three-view drawings of the maintenance tools, eliminating the need for manual regular inspection of the maintenance tools, which is more efficient and convenient, can reduce errors, and saves a large amount of labor.

[0085] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
