Description

Technical Field

[0001] The present invention relates to the maintenance and management of aviation safety components, and in particular to an aviation life jacket management method and device based on RFID. Background Art

[0002] Aviation maintenance refers to the maintenance of time control components to keep the aircraft in a safe state and prevent accidents due to time-related factors. Time control components refer to components or systems that must undergo corresponding functional inspections or tests when due. Checking time control components is a tedious and repetitive task, requiring manual verification of a large amount of information and manual recording, and even requiring the disassembly of oxygen generators one by one when inspecting them. At the same time, in order to avoid the time control components from being overused, they need to be replaced in advance, which in turn wastes the use value of the time control components.

[0003] Therefore, RFID (Radio Frequency Identification) technology was born. RFID is a non-contact automatic identification technology that uses radio frequency signals for communication. It can read multiple objects at the same time and is widely used in airlines' safety protection time controls, including life jackets, biochemical isolation kits and fire extinguishers. Among them, life jackets are taken out by passengers for escape when the aircraft is in a safety situation. They are usually placed under the seats, but due to the working principle of the life jacket itself, they have a time validity period. At the same time, some passengers may take away the life jackets. Therefore, it is necessary to regularly count and inspect the life jackets, and promptly stop and punish the behavior of damaging and taking away the life jackets. Otherwise, the process of replacing the life jackets later is cumbersome and it is impossible to punish the violators in time.

[0004] The existing technology also provides some solutions. Chinese patent CN108364050A proposes a maintenance management system and method for life jackets on civil aircraft. The system includes RFID tags, handheld RFID reading and writing terminals, fixed anti-damage RFID scanning terminals, terminal node management servers and database servers; the fixed anti-damage RFID scanning terminals include RFID reading and scanning modules and alarm devices. The alarm devices are used to alarm when an RFID tag is detected to be present in or passing through the identification range of the scanning terminal placed at the cabin exit. This method adds the initialization of maintenance life jackets. The system and method realize daily inventory inspection, loss prevention management and initialization of new maintenance life jackets, greatly improving the efficiency of life jacket maintenance management and effectively solving the problem of life jackets being taken away by passengers.

[0005] However, this patent has two shortcomings:

[0006] First, some passengers may open the life jackets privately, which may cause irreversible damage, and the method proposed in the patent cannot detect this situation in time;

[0007] Second, passengers may intentionally or unintentionally cause the life jacket to be dislocated from its original position, causing the life jacket to be scattered in the corner. The patent fails to effectively monitor and promptly detect such situations.

[0008] Chinese patent CN208126442U proposes an aircraft life jacket management system based on RFID technology, which includes an RFID fragile seal identification tag, a card writer, a handheld reader / writer and a computer. The card writer is used to write data into the RFID fragile seal identification tag before the life jacket is put into storage. The handheld reader / writer is equipped with a positioning module and an identification module. The computer is equipped with life jacket management software containing an aircraft life jacket configuration database. The RFID fragile seal identification tag is packaged and encapsulated with each aircraft life jacket, and the packaging method should be such that once the life jacket package is opened, the RFID fragile seal identification tag will be damaged. This patent realizes the background automatic management of the validity period of life jackets, saves a lot of manpower and improves the inspection quality, and can timely discover and replace the opened life jackets.

[0009] However, this patent has three shortcomings:

[0010] First, when using this patent, it is impossible to timely discover and stop passengers from taking away life jackets privately, and the process of backing up life jackets later is cumbersome;

[0011] Second, the RFID fragile seal is a disposable product and will be damaged after the life jacket packaging is opened, which has high maintenance costs;

[0012] Third, passengers may intentionally or unintentionally cause the life jacket to be dislocated from its original position, resulting in the life jacket being scattered in a corner, and the patent cannot detect such a situation in time. Summary of the invention

[0043] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0044] Embodiment 1

[0045] An RFID-based aviation life jacket management method, such as Figure 1 As shown, including:

[0046] S1: Place the first RFID tag in a shielding unit that shields radio frequency signals and connect one end of the tag to the packaging bag of the life jacket. The shielding unit is made of metal. Attach the second RFID tag to the seat to which the life jacket belongs. Set a fixed reader at the cabin safety exit and connect it to an alarm unit. The storage information of the first RFID tag includes the seat number of the life jacket. The storage information of the second RFID tag includes the unit number, production traceability information, last inspection date, remaining service life, flight number and seat number of the life jacket.

[0047] S2: The handheld reader scans all seats in the cabin in turn, and maintains or replaces the life jackets that have reached the maintenance time limit or the lower limit of the remaining service life. At the same time, the storage information of the detected second RFID tag is updated through the handheld reader;

[0048] When a passenger carries a life jacket privately through the cabin emergency exit, the first RFID tag on the life jacket packaging bag enters the range of the radio frequency signal emitted by the fixed reader. The fixed reader detects the first RFID tag and triggers the alarm unit, which sounds an alarm through sound or light to promptly discover the violation.

[0049] When a passenger intentionally or unintentionally takes the life jacket out from under the seat, the first RFID tag on the life jacket packaging bag is pulled out from the shielding unit, and the maintenance personnel can detect the first RFID tag through a handheld reader / writer, thereby determining that the life jacket corresponding to the tag is not in place, so that the maintenance personnel can promptly check whether the life jacket is damaged and return the life jacket to its original place.

[0050] The first RFID tag is manufactured together with the corresponding life jacket. The first RFID tag stores production traceability information. When the life jacket is placed under the seat, the production traceability information in the first RFID tag is copied to the second RFID tag. The data in the two tags are updated synchronously, so that the entire life cycle of the life jacket from leaving the factory to warehousing to use can be electronically monitored.

[0051] When the maintenance personnel are performing maintenance, the second RFID tag information is read by scanning, and the information can be automatically entered into the maintenance electronic work order, which effectively improves the maintenance efficiency.

[0052] Embodiment 2

[0053] An RFID-based aviation life jacket management device corresponding to the implementation, such as Figure 2 As shown, it includes a first RFID tag 1, a second RFID tag, a shielding unit 3, a handheld reader 4, a fixed reader, an alarm device 5 and a central computer 2;

[0054] The central computer stores the storage information of the first RFID tag and the second RFID tag and sends an operation instruction, wherein the operation instruction includes an instruction for the handheld reader to erase and write the storage information of the second RFID tag and an instruction for starting the alarm device;

[0055] The handheld reader is used to read the storage information of the first RFID tag and the second RFID tag, and at the same time send the storage information of the first RFID tag and the second RFID tag to the central computer through the wireless communication network and receive the erasing instruction of the central computer;

[0056] The fixed reader is installed at the cabin safety exit and sends the storage information of the detected first RFID tag to the central computer through the wireless communication network;

[0057] The shielding unit is used to block the radio frequency signal to shield the first RFID tag, and the shielding unit is made of metal material;

[0058] like Figure 3As shown, the first RFID tag 1 is placed in the shielding unit 3 and one end is connected to the packaging bag of the life jacket. The storage information of the first RFID tag includes the piece number, production traceability information, flight number and seat number of the life jacket. When the passenger takes out the packaging bag of the life jacket, the first RFID tag will be pulled out of the shielding unit, so that the first RFID tag is in a detectable state;

[0059] The second RFID tag is attached to the seat, and the storage information of the second RFID tag includes the life jacket's piece number, production traceability information, last inspection date, remaining service life, flight number and seat number.

[0060] The first RFID tag is manufactured together with the corresponding life jacket. The first RFID tag stores production traceability information. When the life jacket is placed under the seat, the production traceability information in the first RFID tag is copied to the second RFID tag. The data in the two tags are updated synchronously, so that the entire life cycle of the life jacket from leaving the factory to warehousing to use can be electronically monitored.

[0061] The alarm unit receives the start-up instruction from the central computer through the wireless communication network. When a passenger passes the cabin safety exit with a life jacket, the fixed reader detects the storage information of the first RFID tag on the life jacket packaging bag and transmits the information to the central computer. The central computer sends a start-up instruction to trigger the alarm unit, which sounds an alarm through sound or light to stop the violation in time.

[0062] Embodiment 1 and Embodiment 2 propose an RFID-based aviation life jacket management method and device. In addition to realizing fast and efficient maintenance of life jackets, the behavior of passengers taking life jackets away privately is monitored through a first RFID tag connected to the life jacket packaging bag and a fixed reader at the cabin emergency exit. The first RFID tag, shielding unit and handheld reader are used to monitor whether the life jacket is out of place, and integrity checks and resets are performed in time, so as to safely, efficiently and comprehensively manage life jackets on aircraft.

[0063] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
