Description

Technical Field

[0001] The invention belongs to the technical field of flight support, and in particular relates to a handover management method to prevent airline meal carts from being taken or delivered by mistake. Background Art

[0002] When providing cabin services on board, passengers need to be provided with meals and in-flight supplies. Meals and in-flight supplies are supplied by the catering distribution unit, and the supply process includes two links: distribution and recycling. In the distribution link, the distributor assembles the meals and in-flight supplies into the catering cart, and then the distributor hands over the assembled catering cart to the flight crew. After the flight crew receives the catering cart, they use the catering refrigerated truck to transport the catering cart to the aircraft, and then the flight crew hands over the catering cart to the cabin crew. In the recycling link, the cabin crew assembles the remaining catering supplies in the cabin into the catering cart, and then the cabin crew hands over the assembled catering cart to the flight crew. After the flight crew receives the catering cart, they use the catering refrigerated truck to transport the catering cart back to the catering distribution unit, and then the flight crew hands over the catering cart to the recycling staff. After receiving the catering cart, the recycling staff returns the catering supplies in the catering cart to the warehouse. According to the safety regulations of the Civil Aviation Administration and the management requirements of airline catering distribution units, the dispatcher needs to seal the meal and in-flight supplies after assembling them into the meal cart, and when handing them over to the cabin crew, the seal of the meal cart must be kept intact, without damage or replacement. The cabin crew also needs to seal the meal cart after assembling the remaining in-flight supplies in the cabin, and when handing them over to the collector, the seal of the meal cart must be kept intact, without damage or replacement.

[0003] The existing small dining car handover method has the following defects: 1. During the transportation and handover process, the small dining cart may be taken or delivered by mistake, or even replaced. The seal may also be damaged, replaced or tampered with, which will bring safety risks; 2. Manually use paper documents to register the sealing number of the small dining car, and manually check it during the handover, which is inefficient; 3. It is difficult to find historical data when conducting a security audit. Summary of the invention

[0004] The purpose of the present invention is to provide a handover management method to avoid the mistaking or misdelivering of airline catering carts, to ensure that the catering carts are not mistaken or misdelivered during transportation and handover, and that the seals are intact without damage or replacement, so as to improve the safety management level and work efficiency of catering distribution units.

[0005] To achieve the above object, the present invention provides a handover management method for preventing airline catering carts from being taken or delivered by mistake, comprising the following steps: S1. Construct a handover management system, which includes a distribution task module, an aircraft distribution task module, a cabin handover module, a cabin recovery module, an aircraft recovery task module, and an aircraft supply recovery module; an identification card is provided on the outer wall of the dining cart to be handed over, and the identification card is marked with an identification code and a dining cart number. Each dining cart is sealed by a seal, and the seal is provided with an identification code and a seal number. Use a mobile terminal to scan the identification card and the identification code on the seal, so that the handover management system obtains the corresponding dining cart number and seal number; S2. The dispatcher uses a mobile terminal to receive the flight dispatch task in the dispatch task module, and then selects the number of small dining carts and seals required for the task flight according to the dispatch task content, and then fills in the number of small dining carts selected for the task flight in the dispatch task module, and then assembles the meals and in-flight supplies into the small dining carts, and seals the small dining carts with seals; S3. The dispatcher uses a mobile terminal to scan the identification codes on the dining cart identification card and the seal one by one, so that the dispatch task module obtains the corresponding dining cart number and the seal number. Then, the flight number of the task flight is bound with the corresponding dining cart number and the seal number in the dispatch task module and uploaded to complete the input of the dispatch data. The uploaded dispatch data generates the flight delivery task and the flight service task. The flight delivery task is automatically sent to the aircraft delivery task module, and the flight service task is automatically sent to the cabin handover module. Finally, the dispatcher pushes the dining cart to the dispatch handover area. S4. The crew uses a mobile terminal to receive a flight delivery task in the aircraft delivery task module. According to the information displayed on the delivery task, the crew goes to the distribution and handover area to find the corresponding small meal cart, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the delivery task module obtains the corresponding small meal cart number and the seal number. The delivery task module automatically compares the small meal cart number and the seal number in the delivery task currently executed by the crew with the scanned small meal cart number and the seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft delivery task module prompts that the small meal cart is picked up incorrectly, and the handover is not allowed until the crew finds the correct small meal cart and completes the handover; S5, the flight crew delivers the small meal cart to the cabin of the mission flight, the cabin crew receives the flight service task of the flight in the cabin handover module, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the cabin handover module obtains the corresponding small meal cart number and seal number, and the cabin handover module automatically compares the small meal cart number and seal number in the flight service task currently performed by the cabin crew with the scanned small meal cart number and seal number to see if they are consistent, if they are consistent, the handover is completed; if they are inconsistent, the cabin handover module prompts that the small meal cart is taken or delivered by mistake, and the cabin crew chooses to accept or reject the small meal cart that is taken or delivered by mistake according to the needs, and if they choose to accept, the handover is completed; if they refuse, the flight crew returns the rejected small meal cart to the dispatcher, the dispatcher replaces the small meal cart and the seal, and updates the data in the dispatching task module, updates the flight distribution task and the flight service task, and then repeats steps S4-S5 until the handover is completed; S6. After completing the flight service task, the cabin crew selects the required number of small dining carts according to the number of aircraft supplies to be recovered, and selects the same number of seals. Then, they use the mobile device to fill in the selected number of small dining carts in the cabin recovery module, and then assemble the recovered aircraft supplies into the small dining carts, and seal the door of the small dining cart with a new seal. Then, they use the mobile device to scan the identification codes on the small dining cart identification card and the seal one by one, so that the cabin recovery module obtains the small dining cart number and the seal number. Then, in the cabin recovery module, the flight number of the flight is bound with the small dining cart number and the seal number and uploaded, completing the entry of the recovery data. The uploaded recovery data generates a flight recovery task, and the flight recovery task is automatically sent to the aircraft recovery task module and the aircraft supply recovery module. S7. After the plane lands, the crew uses the mobile terminal to receive the corresponding flight recovery task in the aircraft recovery task module. The crew goes to the corresponding flight cabin to pick up the small meal cart to be recovered, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the aircraft recovery task module obtains the small meal cart number and the seal number. The aircraft recovery task module automatically compares the small meal cart number and the seal number in the flight recovery task currently executed by the crew with the scanned small meal cart number and the seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft recovery task module prompts that the small meal cart is taken or delivered by mistake, and does not allow the handover until the crew picks up the correct small meal cart and completes the handover; S8. The crew transports the small dining cart to the aircraft supply recycling station. The recycling staff uses the mobile device to receive the corresponding flight recycling task in the aircraft supply recycling module. Then, the recycling staff uses the mobile device to scan the identification card of the recycled small dining cart and the identification code on the seal, so that the aircraft supply recycling module obtains the corresponding small dining cart number and seal number. The aircraft supply recycling module automatically compares the small dining cart number and seal number in the flight recycling task currently executed by the recycling staff with the scanned small dining cart number and seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft supply recycling module reminds the small dining cart to be taken or delivered by mistake, and does not allow the handover until the crew finds the correct small dining cart to be recycled and completes the handover: S9. The auditor retrieves the catering cart data and seal data of the corresponding flight based on the flight date and flight number in the background of the handover management system to check whether the catering cart and seal are consistent and intact during the handover process, and complete the security log audit work.

[0006] Further, in step S6, the cabin recovery module is provided with an automatic data upload process. If the flight is in operation in the air when the cabin crew enters the recovery data, the cabin recovery module automatically detects whether the network conditions for uploading the data are available. If not, after the cabin crew enters the recovery data, the cabin recovery module will cache the recovery data. After detecting that the network conditions are available, the cabin recovery module will upload the recovery data to complete the entry of the recovery data. If the upload fails, the cabin recovery module prompts that the automatic data upload fails, and the cabin crew uses the cabin recovery module on the mobile device to manually upload the recovery data.

[0007] Further, in step S5, after the flight service task module prompts that the meal cart is taken or delivered by mistake, if the cabin crew chooses to accept the meal cart, the mobile terminal is used to fill in the notes of receipt in the cabin handover module; if the cabin crew chooses to refuse to accept the meal cart, the flight crew returns the refused meal cart to the distributor, who replaces the meal cart and the seal, updates the data in the distribution task module, and fills in the notes of replacing the meal cart and the seal; in step S8, after the in-flight supply recovery module prompts that the meal cart is taken or delivered by mistake, if the flight crew cannot find the correct meal cart, the recovery staff uses the mobile terminal to fill in the notes of the in-flight supply recovery module that the meal cart is taken or delivered by mistake and the flight crew cannot find it; in step S9, the auditor views the data of the notes of all modules during the handover process in the background of the handover management system.

[0008] Further, in step S3, the distributor uses the mobile terminal to scan the identification codes on the dining cart identification card and the sealing strip one by one, so that the distribution task module obtains the corresponding dining cart number and the sealing strip number, and then the distribution task module automatically verifies whether the number of dining carts filled in by the distributor is consistent with the number of dining carts and the number of sealing strips scanned by the distributor using the mobile device. If they are consistent, the subsequent steps are performed; if they are not consistent, the distribution task module prompts the distributor that the data entry is wrong and does not allow the distribution data to be entered until the number of dining carts filled in by the distributor is consistent with the number of dining carts and the number of sealing strips scanned, and then the distribution data is allowed to be entered; in step S6, similar to step S3, the cabin crew uses the mobile device to scan the identification codes on the dining cart identification card and the sealing strip one by one, so that the cabin recovery module obtains the dining cart number and the sealing strip number, and then the cabin recovery module automatically verifies whether the number of dining carts filled in by the cabin crew is consistent with the number of dining carts and the number of sealing strips scanned by the cabin crew using the mobile device, so as to complete the entry of the recovery data.

[0009] Further, in step S3, during the process of completing the entry of distribution data and pushing the dining cart to the distribution handover area, if the distributor finds that the seal on the dining cart is damaged, the distributor will remove the damaged seal, use a new seal to reseal and lock the dining cart, and then delete the damaged seal number data in the distribution task module, scan the identification code of the new seal, and update the data; if the distributor finds that the dining cart is faulty, the distributor will replace it with a new one, use a new seal to seal and lock the dining cart, and then delete the seal number data and dining cart number data to be replaced in the distribution task module, scan the identification codes of the new dining cart and seal, and update the data.

[0010] Furthermore, in step S4, during the handover process of the meal cart received by the crew in the distribution and handover area, if the crew finds that the meal cart is faulty or the seal is damaged, the crew will return the meal cart to the distributor, who will replace the meal cart or the seal and update the data in the distribution task module. The crew will then refresh the flight delivery task in the aircraft handover task module and scan the identification code of the replaced meal cart and the seal again for comparison until the handover is completed.

[0011] Further, in step S6, if the cabin crew finds that the seal on the recovered meal trolley is damaged during the process of completing the recovery data entry, they will remove the damaged seal, use a new seal to seal and lock the meal trolley, and then delete the damaged seal number data in the cabin recovery module, rescan the identification code of the new seal, and update the data; in step S7, if the crew finds that the seal of the meal trolley is damaged during the handover process of receiving the meal trolley to be recycled, they will require the cabin crew to reseal and lock the meal trolley and update the data, and then rescan the updated seal until the handover is completed.

[0012] Furthermore, in step S5, the crew delivers the small meal cart to the cabin of the mission flight to complete the handover with the cabin crew. The crew delivers a sufficient number of seals to the cabin crew for use by the cabin crew when retrieving the aircraft supplies.

[0013] Further, in steps S1-S8, the seal strip is composed of a seal body and a cassette, the seal body is provided with an information display area, a card slot and an easy-tear line, the information displayed in the information display area includes the name of the airline, the seal strip number, the seal strip number and an identification code, the identification code of the seal strip is a bar code or a QR code, the card slot is located on one side of the information display area, the cassette is formed by extending from the side of the seal body, and the back of the cassette is provided with reverse teeth. When blocking the dining cart, the cassette is passed through the lock of the dining cart and then through the card slot so that the reverse teeth on the back of the cassette are clamped with the card slot to complete the blocking of the dining cart, and the easy-tear line is located between the cassette and the card slot, and the easy-tear line facilitates tearing open the seal.

[0014] Further, in steps S1-S8, the identification card is fixed above the lock on the front of the dining cart, and the identification card is marked with the airline name, identification code and dining cart number, and the identification code on the identification card is a QR code or a bar code.

[0015] After adopting the above scheme, the beneficial effects of the present invention are: 1. The present invention uses a mobile terminal to scan the identification code on the dining cart identification card and the seal to quickly bind and upload the flight number, dining cart number, and seal number, so that the flight, dining cart, and seal can correspond to each other. In all subsequent handover processes, the corresponding handover personnel need to use the mobile terminal to scan the identification code on the dining cart identification card and the seal. The handover management system will automatically compare the dining cart number and seal number recorded in the task with the scanned dining cart number and seal number. Only when they are consistent can the handover be allowed, ensuring that the dining cart will not be taken or delivered by mistake during transportation and handover, and the seal is intact without damage or replacement, thereby improving the safety management level of the meal distribution unit; 2. Use mobile terminals to scan and input data throughout the process, and the handover management system automatically checks whether the number of the small dining car and the seal number handed over are correct, which improves the work efficiency of the food distribution unit; 3. All data of the handover process can be viewed in the background of the handover management system. Auditors can check whether the food carts and seals are consistent and intact during the entire handover process, complete the information monitoring of the handover process, and can also combine the handover personnel's remarks to hold accountable the handover personnel who deliberately lose the food carts or other maliciously disrupt the handover process, making it easy to complete the security log audit.

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The present invention provides a handover management method to avoid the mis-taking or mis-delivery of airline catering carts. The entire handover management process must rely on a handover management system. The handover personnel include the dispatcher, flight attendant, cabin crew and collector. Figure 2-3 As shown, the present invention sets an identification card 2 on the outer wall of the small dining cart 1 that needs to be handed over. The identification card 2 is marked with information such as the airline LOGO 4, the airline name 5, the identification code 6 and the small dining cart number 7, which is convenient for the handover personnel to find and confirm. The identification code 6 on the identification card 2 can be a QR code or a bar code. The handover personnel can obtain the small dining cart number 7 by scanning the identification code with a mobile terminal, and enter the small dining cart number 7 into the handover management system.

[0020] Each food cart is sealed with a signature seal. Figure 1As shown, the seal 3 is composed of a seal body 31 and a card tape 32. The seal body 31 is provided with an information display area 311, a card slot 312 and a tear line 313. The information displayed in the information display area 311 includes the airline LOGO 4, the airline name 5, the seal number 5, the seal number 8 and the identification code 6. The displayed information is also convenient for the handover personnel to find and confirm. The identification code 6 of the seal 3 can also be a bar code or a QR code. By scanning the identification code with a mobile terminal, the seal number can be obtained and the seal number can be entered into the handover management system. The card slot 312 is located at one side of the information display area 311, and the card belt 32 is formed by extending from the side of the seal body 31. The back of the card belt 32 is provided with reverse teeth. When sealing the small dining cart, the card belt 32 is passed through the lock buckle 11 of the small dining cart, and then passed through the card slot 312, so that the reverse teeth on the back of the card belt 32 are clamped with the card slot 312, and the sealing of the small dining cart is completed; the easy tear line 313 is located between the card belt 32 and the card slot 312, and the easy tear line 313 is composed of a series of fine small holes, and the signature seal can be easily torn off along the easy tear line 313.

[0021] It should be noted that the catering cart number and the seal number are unique and non-repeatable numbers. The numbering rule of the catering cart number can be the two-letter airline code + DC + purchase year + six-digit self-incremental numbers. The self-incremental numbers start from 000001 every year, and the overall number is similar to MFDC2024000001. The numbering rule of the seal number is the two-letter airline code + year + eight-digit self-incremental numbers. The self-incremental numbers start from 00000001 every year, and the overall number is similar to MF202400000001.

[0022] As a preferred embodiment, the identification card can be a 5mm×5mm square aluminum alloy plate, which can be bound above the lock on the front of the small dining cart to facilitate the handover personnel to scan the code.

[0023] The handover management method comprises the following steps: S1. Construct a handover management system, which includes a distribution task module, an aircraft distribution task module, a cabin handover module, a cabin recovery module, an aircraft recovery task module, and an aircraft supply recovery module. These modules all have data acquisition and verification functions, and can obtain the catering cart number and the seal number by scanning the identification code on the catering cart identification card and the seal through a mobile terminal, and can perform verification based on the obtained number data.

[0024] S2. The dispatcher uses a mobile terminal to receive all flight dispatch tasks in the dispatch task module, and can complete all flight dispatch tasks in sequence according to the flight take-off time. The specific completion process is: first, select the required number of small dining carts and seals for each flight in sequence according to the dispatch task content, that is, first select a flight in the task content, expand the task content of meals and in-flight supplies to be dispatched for the flight, select the required number of small dining carts according to the task content, and select the same number of small dining cart seals, then fill in the number of small dining carts selected for each task flight in the dispatch task module, then assemble the meals and in-flight supplies into the small dining carts, and seal the small dining carts with seals.

[0025] S3. The dispatcher uses a mobile terminal to scan the identification codes on the dining cart identification card and the seal one by one, so that the distribution task module obtains the corresponding dining cart number and seal number. Then, the flight number of the task flight is bound with the corresponding dining cart number and seal number in the distribution task module and uploaded, completing the input of the distribution data. The format of the entered data is shown in the following table:

[0026] Table 1-Data format table for distribution task module input When entering data, the small food cart number and the seal number do not need to correspond strictly in order, but the number of the two numbers must correspond. After scanning and obtaining the small food cart number and the seal number, the distribution task module will automatically verify whether the number of small food carts filled in by the distributor is consistent with the number of small food carts and the number of seals scanned by the distributor using the mobile device. If they are consistent, the subsequent steps will be carried out to complete the entry of the distribution data; if they are inconsistent, the distribution task module will prompt the distributor that the data entry is incorrect and will not allow the distribution data to be completed. The distributor needs to check whether there are any missing small food cart numbers or seal numbers, and then add the missing numbers until the distribution task module verifies that the number of small food carts filled in by the distributor is consistent with the scanned number of small food carts and the number of seals, and then the distribution data is allowed to be entered. The uploaded distribution data will generate flight distribution tasks and flight service tasks. The flight distribution tasks are automatically sent to the aircraft distribution task module, and the flight service tasks are automatically sent to the cabin handover module. The flight distribution tasks and flight service tasks can be generated and sent by the distribution task module, or the distribution data can be uploaded to the handover management system and generated and sent by the handover management system.

[0027] Finally, the distributor pushes the small meal cart to the distribution handover area, and then selects the next flight's distribution task in sequence to complete the next flight's distribution task, and repeats this process to complete all flight recipe tasks. When the distributor completes the entry of distribution data and pushes the small dining cart to the distribution handover area, if the seal on the small dining cart is found to be damaged, the distributor can remove the damaged seal, use a new seal to reseal and lock the small dining cart, and then delete the damaged seal number data in the distribution task module, scan the identification code of the new seal, and update the data; similarly, if the distributor finds that the small dining cart is faulty, he / she can remove the seal of the faulty small dining cart, replace it with a new one, use the new seal to seal and lock the small dining cart, and then delete the seal number data and small dining cart number data to be replaced in the distribution task module, scan the identification code of the new small dining cart and seal, and update the data. When the distributor replaces the new seal or small dining cart, he / she can fill in the reason for the replacement in the distribution task module. The remarks data can be retrieved and queried by the auditors in the handover management system.

[0028] S4. The crew uses the mobile terminal to receive the flight delivery task in the aircraft delivery task module. According to the information displayed in the delivery task, they go to the distribution and handover area to find the corresponding small dining cart. They can check the small dining cart number on the small dining cart identification card to find it. After finding all the corresponding small dining carts, they use the mobile terminal to scan the small dining cart identification card and the identification code on the seal one by one, so that the delivery task module obtains the corresponding small dining cart number and the seal number. The delivery task module automatically compares the small dining cart number and the seal number in the delivery task currently executed by the crew with the scanned small dining cart number and the seal number. If they are consistent, the handover is completed; if not, the aircraft delivery task module prompts that the small dining cart is picked up incorrectly and the handover is not allowed. The crew needs to find the correct small dining cart again, and then scan the corresponding identification code again until the crew finds the correct small dining cart. The handover can only be completed when the delivery task module compares the data and it is consistent. After completing the delivery task of the flight, the crew receives the flight delivery task of the next flight through the aircraft delivery task module.

[0029] like Figure 5As shown, the distribution task module compares the label data to see if they are consistent in the following way: split the catering cart number character string in the flight distribution task into catering cart number arrays according to “ / ”, and compare whether the scanned catering cart number is the same as any data in the catering cart number array. If they are the same, mark the corresponding data in the catering cart number array as “same”; similarly, split the seal number character string in the flight distribution task into seal number arrays according to “ / ”, and compare whether the scanned seal number is the same as any data in the seal number array. If they are the same, mark the corresponding data in the seal number array as “same”; when all the data in the catering cart number array and the seal number array are marked as “same”, the distribution task module determines that the data is consistent, otherwise it is determined that the data is inconsistent.

[0030] Furthermore, during the handover process of the meal cart received by the crew in the distribution and handover area, if the crew finds that the meal cart is faulty or the seal is damaged, the crew can return the meal cart to the distributor. The distributor replaces the meal cart or the seal and updates the data in the distribution task module. The crew then refreshes the flight delivery task in the aircraft handover task module and scans the identification code of the replaced meal cart and the seal again for comparison until the comparison is consistent and the handover is completed.

[0031] S5. The crew delivers the meal cart to the cabin of the mission flight. The cabin crew receives the flight service task of the flight in the cabin handover module, and then uses the mobile terminal to scan the identification code on the meal cart identification card and the seal one by one, so that the cabin handover module obtains the corresponding meal cart number and seal number. The cabin handover module automatically compares the meal cart number and seal number in the flight service task currently performed by the crew with the scanned meal cart number and seal number to see if they are consistent. The comparison method is the same as the method in step S4. If the comparison is consistent, the handover is completed; if not, the cabin handover module prompts that the meal cart is taken or delivered by mistake. The cabin crew can choose to receive or reject the meal cart that is taken or delivered by mistake according to their needs. If the flight is about to take off, it may be too late for the crew to redistribute the meal cart, so the cabin crew can choose to receive the meal cart and fill in the remarks of the receipt in the cabin handover module for subsequent audit inquiry to complete the handover. If there is enough time, the cabin crew can choose to refuse to accept the meal cart, and the flight attendant needs to return the rejected meal cart to the dispatcher. The dispatcher checks whether the meal cart is delivered incorrectly, replaces the meal cart and signs the seal, and updates the data in the dispatch task module, updates the flight delivery task and flight service task, and then repeats steps S4-S5 until the handover is completed.

[0032] Furthermore, when the flight crew delivers the small meal cart to the cabin of the mission flight to complete the handover with the cabin crew, the flight crew can hand over a sufficient number of seals to the cabin crew for use by the cabin crew when subsequently recovering the aircraft supplies.

[0033] S6. The cabin crew tears off the seal of the dining cart, then opens the dining cart to take out the meals and in-flight supplies and supply them to the passengers to complete the cabin flight service. After completion, the dining cart is empty, and the cabin crew needs to select the required number of dining carts according to the number of in-flight supplies that need to be recovered. They can choose from the empty dining carts and select the same number of seals, and then use the mobile device to fill in the selected number of dining carts in the cabin recovery module, and then assemble the recovered in-flight supplies into the dining cart, and seal the door of the dining cart with a new seal; then use the mobile device to scan the identification code on the dining cart identification card and the seal one by one, so that the cabin recovery module obtains the dining cart number and the seal number, and then binds the flight number of the flight with the dining cart number and the seal number in the cabin recovery module and uploads them to complete the entry of the recovery data. The format of the entered data is shown in the following table:

[0034] Table 2-Data format table for cabin recovery module input Similar to the distribution data input by the dispatcher, the catering cart number and the seal number do not need to correspond strictly in order, and after scanning and obtaining the catering cart number and the seal number, the cabin recovery module will automatically check whether the number of catering carts filled in by the cabin crew is consistent with the number of catering carts and the number of seals scanned by the cabin crew using the mobile device. If they are consistent, the subsequent steps will be carried out to complete the entry of the recovery data; if they are not consistent, the cabin recovery module will prompt the cabin crew that the data entry is wrong and will not allow the completion of the entry of the recovery data. The cabin crew needs to check whether there are any missing catering cart numbers or seal numbers, and then supplement the missing numbers until the cabin recovery module verifies that the number of catering carts filled in by the cabin crew is consistent with the number of catering carts and the number of seals scanned, and then the recovery data is allowed to be completed. The uploaded recovery data will generate a flight recovery task, which is automatically sent to the aircraft recovery task module and the aircraft supply recovery module. The flight recovery task can also be generated and sent by the cabin recovery module, or by the handover management system.

[0035] Furthermore, the cabin recovery module is also provided with an automatic data upload process. If the flight is in operation in the air when the cabin crew is entering the recovery data, there may not be network conditions for automatically uploading the data. The cabin recovery module will automatically detect whether the network conditions for uploading the data are met. If not, after the cabin crew enters the recovery data, the cabin recovery module will cache the recovery data. After detecting that the network conditions are met, the cabin recovery module will upload the recovery data to complete the entry of the recovery data. If the cabin recovery module fails to upload the recovery data due to network problems after uploading the recovery data, the cabin recovery module prompts that the automatic data upload fails, and the cabin crew can use the cabin recovery module on the mobile device to manually upload the recovery data.

[0036] In addition, when the cabin crew is completing the process of entering the recovery data, if they find that the seal on the recovered food cart is damaged, they can remove the damaged seal, use a new seal to seal and lock the food cart, and then delete the damaged seal number data in the cabin recovery module, rescan the identification code of the new seal, update the data, and at the same time note the reason for the replacement in the cabin recovery module.

[0037] S7. After the plane lands, the crew uses the mobile terminal to receive the corresponding flight recovery task in the aircraft recovery task module. The crew goes to the corresponding flight cabin to pick up the small meal cart to be recovered, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the aircraft recovery task module obtains the small meal cart number and the seal number. The aircraft recovery task module automatically compares the small meal cart number and the seal number in the flight recovery task currently executed by the crew with the scanned small meal cart number and the seal number to see if they are consistent. The comparison method is the same as that in steps S4 and S5. If the comparison is consistent, the handover is completed; if the comparison is inconsistent, the aircraft recovery task module prompts that the small meal cart is taken or delivered by mistake, and the handover is not allowed. The crew needs to check whether there is a small meal cart whose identification code has not been scanned, or ask the cabin crew to help check whether the small meal cart is correct, until the crew picks up the correct small meal cart to be recovered, and the aircraft recovery task module verifies that they are consistent, and the handover is completed.

[0038] Furthermore, when the crew is collecting the meal cart for recycling and finds that the seal of the meal cart is damaged, they can ask the cabin crew to reseal and lock the meal cart and update the data, and then rescan the updated seal until the aircraft recycling task module verifies and completes the handover.

[0039] S8. The crew transports the small meal cart to the in-flight supplies recycling place. The recycler uses the mobile device to receive the corresponding flight recycling task in the in-flight supplies recycling module. Then, the mobile device is used to scan the identification card of the recycled small meal cart and the identification code on the seal, so that the in-flight supplies recycling module obtains the corresponding small meal cart number and seal number. The in-flight supplies recycling module automatically compares the small meal cart number and seal number in the flight recycling task currently executed by the recycler with the scanned small meal cart number and seal number to see if they are consistent. The comparison method is the same as that in steps S4, S5 and S7. If they are consistent, the handover is completed; if they are inconsistent, the in-flight supplies recycling module reminds the small meal cart to be taken or delivered by mistake, and the handover is not allowed until the crew finds the correct small meal cart to be recycled, and the in-flight supplies recycling module verifies that they are consistent, and the handover is completed; if the crew does not find the correct small meal cart, the recycler notes the reason for not recycling in the in-flight supplies recycling module, and the crew will be held accountable later.

[0040] S9. The auditor retrieves the catering cart data, seal data and notes data of the corresponding flight in the background of the handover management system according to the flight date and flight number. The auditor can check whether the catering cart and seal are consistent and intact during the entire handover process. If the catering cart is lost or damaged, the corresponding handover personnel can be held accountable to complete the security log audit.

[0041] In summary, the present invention uses a mobile terminal to scan the identification code on the dining cart identification card and the seal to quickly bind and upload the flight number, dining cart number, and seal number, so that the flight, dining cart, and seal can correspond to each other. In all subsequent handover processes, the corresponding handover personnel need to use the mobile terminal to scan the identification code on the dining cart identification card and the seal. The handover management system will automatically compare the dining cart number and seal number recorded in the task to see if they are consistent with the scanned dining cart number and seal number. Only if they are consistent, the handover is allowed (except for the special circumstances in step S5), ensuring that the dining cart will not be taken or delivered by mistake during transportation and handover, and the seal is intact and not damaged or replaced, thereby improving the safety management level and work efficiency of the meal distribution unit.

[0042] In addition, the entire handover process relies on the handover management system to enter and review data. All handover data in the handover process can be retrieved and viewed in the background of the handover management system. It can confirm whether the food cart and seals are consistent and intact, and complete the information monitoring of the handover process. It can also be combined with the handover personnel's remarks to hold accountable the handover personnel who deliberately lose the food cart or otherwise maliciously disrupt the handover process.

[0043] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.

Each dining cart is sealed by a seal, and the seal is provided with an identification code and a seal number. Use a mobile terminal to scan the identification card and the identification code on the seal, so that the handover management system obtains the corresponding dining cart number and seal number; S2. The dispatcher uses a mobile terminal to receive the flight dispatch task in the dispatch task module, and then selects the number of small dining carts and seals required for the task flight according to the dispatch task content, and then fills in the number of small dining carts selected for the task flight in the dispatch task module, and then assembles the meals and in-flight supplies into the small dining carts, and seals the small dining carts with seals; S3. The dispatcher uses a mobile terminal to scan the identification codes on the dining cart identification card and the seal one by one, so that the dispatch task module obtains the corresponding dining cart number and the seal number. Then, the flight number of the task flight is bound with the corresponding dining cart number and the seal number in the dispatch task module and uploaded to complete the input of the dispatch data. The uploaded dispatch data generates the flight delivery task and the flight service task. The flight delivery task is automatically sent to the aircraft delivery task module, and the flight service task is automatically sent to the cabin handover module. Finally, the dispatcher pushes the dining cart to the dispatch handover area. S4. The crew uses a mobile terminal to receive a flight delivery task in the aircraft delivery task module. According to the information displayed on the delivery task, the crew goes to the distribution and handover area to find the corresponding small meal cart, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the delivery task module obtains the corresponding small meal cart number and the seal number. The delivery task module automatically compares the small meal cart number and the seal number in the delivery task currently executed by the crew with the scanned small meal cart number and the seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft delivery task module prompts that the small meal cart is picked up incorrectly, and the handover is not allowed until the crew finds the correct small meal cart and completes the handover; S5, the flight crew delivers the small meal cart to the cabin of the mission flight, the cabin crew receives the flight service task of the flight in the cabin handover module, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the cabin handover module obtains the corresponding small meal cart number and seal number, and the cabin handover module automatically compares the small meal cart number and seal number in the flight service task currently performed by the cabin crew with the scanned small meal cart number and seal number to see if they are consistent, if they are consistent, the handover is completed; if they are inconsistent, the cabin handover module prompts that the small meal cart is taken or delivered by mistake, and the cabin crew chooses to accept or reject the small meal cart that is taken or delivered by mistake according to the needs, and if they choose to accept, the handover is completed; if they refuse, the flight crew returns the rejected small meal cart to the dispatcher, the dispatcher replaces the small meal cart and the seal, and updates the data in the dispatching task module, updates the flight distribution task and the flight service task, and then repeats steps S4-S5 until the handover is completed; S6. After completing the flight service task, the cabin crew selects the required number of small dining carts according to the number of aircraft supplies to be recovered, and selects the same number of seals. Then, they use the mobile device to fill in the selected number of small dining carts in the cabin recovery module, and then assemble the recovered aircraft supplies into the small dining carts, and seal the door of the small dining cart with a new seal. Then, they use the mobile device to scan the identification codes on the small dining cart identification card and the seal one by one, so that the cabin recovery module obtains the small dining cart number and the seal number. Then, in the cabin recovery module, the flight number of the flight is bound with the small dining cart number and the seal number and uploaded, completing the entry of the recovery data. The uploaded recovery data generates a flight recovery task, and the flight recovery task is automatically sent to the aircraft recovery task module and the aircraft supply recovery module. S7. After the plane lands, the crew uses the mobile terminal to receive the corresponding flight recovery task in the aircraft recovery task module. The crew goes to the corresponding flight cabin to pick up the small meal cart to be recovered, and then uses the mobile terminal to scan the identification code on the small meal cart identification card and the seal one by one, so that the aircraft recovery task module obtains the small meal cart number and the seal number. The aircraft recovery task module automatically compares the small meal cart number and the seal number in the flight recovery task currently executed by the crew with the scanned small meal cart number and the seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft recovery task module prompts that the small meal cart is taken or delivered by mistake, and does not allow the handover until the crew picks up the correct small meal cart and completes the handover; S8. The crew transports the small dining cart to the aircraft supply recycling station. The recycling staff uses the mobile device to receive the corresponding flight recycling task in the aircraft supply recycling module. Then, the recycling staff uses the mobile device to scan the identification card of the recycled small dining cart and the identification code on the seal, so that the aircraft supply recycling module obtains the corresponding small dining cart number and seal number. The aircraft supply recycling module automatically compares the small dining cart number and seal number in the flight recycling task currently executed by the recycling staff with the scanned small dining cart number and seal number to see if they are consistent. If they are consistent, the handover is completed; if they are inconsistent, the aircraft supply recycling module reminds the small dining cart to be taken or delivered by mistake, and does not allow the handover until the crew finds the correct small dining cart to be recycled and completes the handover: S9. The auditor retrieves the catering cart data and seal data of the corresponding flight based on the flight date and flight number in the background of the handover management system to check whether the catering cart and seal are consistent and intact during the handover process, and complete the security log audit work.

A handover management method for preventing airline catering carts from being taken or delivered by mistake as claimed in claim 1, characterized in that: In step S6, the cabin recovery module is provided with an automatic data upload process. If the flight is in operation in the air when the cabin crew enters the recovery data, the cabin recovery module automatically detects whether the network conditions for uploading the data are available. If not, after the cabin crew enters the recovery data, the cabin recovery module will cache the recovery data. After detecting that the network conditions are available, the cabin recovery module will upload the recovery data to complete the entry of the recovery data. If the upload fails, the cabin recovery module prompts that the automatic data upload fails, and the cabin crew uses the cabin recovery module on the mobile device to manually upload the recovery data.

3. A handover management method for preventing airline catering carts from being taken or delivered by mistake as claimed in claim 1, characterized in that: In step S5, after the flight service task module prompts that the meal cart is taken or delivered by mistake, if the cabin crew chooses to accept the meal cart, they will use the mobile terminal to fill in the notes of receipt in the cabin handover module; if the cabin crew chooses to refuse to accept the meal cart, the flight attendant will return the refused meal cart to the distributor, who will replace the meal cart and the seal, update the data in the distribution task module, and fill in the notes of replacing the meal cart and the seal; in step S8, after the in-flight supply recovery module reminds that the meal cart is taken or delivered by mistake, if the flight crew cannot find the correct meal cart, the recovery staff will use the mobile terminal to fill in the notes of the in-flight supply recovery module that the meal cart is taken or delivered by mistake and the flight crew cannot find it; in step S9, the auditor will view the data of the notes of all modules in the handover process in the background of the handover management system.

4.
