Description

Technical Field

[0001] This invention relates to the field of intelligent sensor rack technology, and more specifically, to a method and system for barcode scanning and shelving prompts applied to intelligent sensor racks. Background Technology

[0002] Intelligent sensor racks are a new type of rack with material sensing and detection functions for trays. Each storage location on the rack is usually configured with a storage location code, and a sensor is set up at each storage location to read the placed tray. All this information is controlled by a host system. Currently, when loading trays onto intelligent sensor racks, the prompts used are varied and lack a unified standard. Moreover, the prompts are not comprehensive and are too simplistic, failing to provide targeted and effective prompts for the various errors that may occur during the loading process. The formal significance of the prompts far outweighs their actual practical value. After receiving error prompts, the rack operator still needs to check the location of the error according to the internal inspection procedures.

[0003] These types of errors include: incorrect rack placement (this is a common and easily overlooked error, especially when there are many racks and they are densely distributed), no empty storage space on the rack, the tray not being on the receiving slip (the receiving slip is a list of trays to be placed on the current rack; this error occurs because the wrong tray was taken), the storage space on the rack being occupied (this error occurs because tray A was scanned but tray B was placed; this is due to human error and is relatively hidden and difficult to detect), and the tray size not matching the rack size (the storage space size on the rack does not match the tray size). Based on these reasons, a scanning and placement prompt method and system for intelligent sensor racks is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a barcode scanning and shelving prompt method for intelligent induction racks, and to provide a barcode scanning and shelving prompt system for intelligent induction racks, in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A method for barcode scanning and shelving notification applied to intelligent sensor-operated material racks is constructed, characterized in that the method includes the following steps:

[0007] Receive and determine if the rack code is correct. If it is correct, proceed to the next step. Otherwise, prompt the rack error and re-enter the rack code receiving state.

[0008] Read the current number of empty storage positions on the rack and determine if the number of empty storage positions is zero. If it is not zero, proceed to the next step; otherwise, indicate that there are no empty storage positions on the rack and end the current pallet loading process.

[0009] Bind the record rack code and prompt the user to scan the unique code of the tray to be racked.

[0010] Receive and determine if the unique code of the material tray is correct. If it is correct, proceed to the next step; otherwise, prompt that the material tray is incorrect and re-enter the state of receiving the unique code of the material tray.

[0011] Determine if the unique code of the received tray matches the unique code of the tray already on the rack. If not, proceed to the next step. If they match, indicate that the unique code of the tray is duplicated, light up the indicator, and set the storage position of the matching tray to the retrievable state.

[0012] Determine whether the material specifications contained in the unique code match the storage location specifications of the rack, and also determine whether there are empty storage locations on the rack. If the material specifications match the storage location specifications of the rack and there are empty storage locations on the rack, proceed to the next step. If the material specifications do not match the storage location specifications of the rack, issue a mismatch prompt and end the current pallet loading process. If there are no empty storage locations on the rack, issue a no-empty-storage-location prompt and end the current pallet loading process.

[0013] Record the unique code and start the countdown to proceed to the next step;

[0014] Determine whether the storage code of the storage position of the material rack is received before the countdown ends. If yes, proceed to the next step; otherwise, prompt that the racking timeout has occurred and scan the code again to put the material rack into place.

[0015] Record and bind the storage location code and the unique code of the material tray, store them in the valid material loading dataset, prompt that the material tray has been successfully loaded, and decrement the number of empty storage locations on the rack by one.

[0016] The present invention provides a method for scanning and placing items on a smart sensor rack, wherein the method further includes:

[0017] After the material loading process begins, monitor the status of each storage location on the material rack;

[0018] When the status of a storage location changes, determine whether there is a material tray in the changed storage location. Otherwise, proceed to the illegal removal process; otherwise, proceed to the next step.

[0019] Read the storage location code of the storage location placed in the material tray, and determine whether the read storage location code belongs to a valid material loading dataset. If it does, determine that the storage location status is normal and end this unscanned barcode placement event; otherwise, determine that the storage location is in an unscanned barcode placement state and proceed to the next step.

[0020] Add the storage code of the unscanned storage location to the exception dataset and indicate that there is a storage location that has not been scanned.

[0025] Upon receiving the input command to clear the unscanned barcode placement status of the storage location, the process for clearing the unscanned barcode placement status of the storage location begins.

[0026] Receive the rack code of the current rack and read the abnormal dataset corresponding to the rack code;

[0027] Determine if the unscanned and placed status data in the abnormal dataset is empty. If it is, indicate that there is no abnormality in the rack and end the process. Otherwise, indicate that the unscanned and placed tray should be removed and proceed to the next step.

[0028] Monitor the status of each storage location on the material rack;

[0029] Determine whether the unscanned tray has been removed. If yes, proceed to the next step; otherwise, return to the previous step.

[0030] The message indicates that the "unscanned barcode placement" status has been removed, the color of the storage space light has been changed to the normal color, and the corresponding "unscanned barcode placement" status data has been deleted from the abnormal data set.

[0031] Determine if the unscanned barcode placement status data in the abnormal dataset is empty. If yes, proceed to the next step; otherwise, return to the step of monitoring the status of each storage location on the material rack.

[0037] Receive and determine whether the unique code of the returned material tray is the unique code of the illegally taken material tray. If it is, prompt the tray to be put back on the shelf and proceed to the next step; otherwise, prompt the tray return error.

[0038] Record the unique code of the material tray and start the countdown;

[0039] Before the countdown ends, determine whether the storage location code of the returned material tray has been received from the storage location on the material rack. If yes, proceed to the next step; otherwise, prompt that the racking timeout has occurred and return to the step of receiving and determining whether the unique code of the returned material tray is the unique code of the illegally retrieved material tray.

If yes, proceed to the next step.

[0043] Determine if there are any abnormalities in the remaining storage locations on the material rack. If so, proceed with the corresponding abnormality handling process; otherwise, indicate that the abnormality has been resolved and end the illegal removal handling process.

[0051] The present invention describes a barcode scanning and shelving prompt method for intelligent sensor-operated material racks, wherein the step of determining whether the material rack has been scanned multiple times before shelving, and if so, prompting a barcode error; otherwise, proceeding to the next step includes:

[0052] Assign a value of 1 to the number of scans;

[0069] A preferred embodiment of the present invention is a barcode scanning and shelving prompt method applied to an intelligent sensor-operated material rack, such as... Figure 1 As shown, see also Figures 2-5 The steps include:

[0070] S01: Receive and verify the rack code. If correct, proceed to the next step; otherwise, indicate a rack error and re-enter the rack code receiving state. Specific steps can be as follows:

[0071] Enter the information receiving state to receive the rack code information of the rack to be racked;

[0072] If the rack code information is received within the set time, proceed to the next step; otherwise, prompt the user to scan the rack code again and return to the previous step.

[0073] Determine if the received rack code information is correct. If correct, proceed to the next step; otherwise, indicate that the rack code information is incorrect and return to the previous step.

[0074] S02: Read the current empty storage position of the rack and determine whether the empty storage position is zero. If it is not zero, proceed to the next step; otherwise, indicate that there is no empty storage position on the rack and end the current pallet loading process.

[0075] S03: Bind and record the rack code, prompting you to scan the unique code of the tray to be racked;

[0076] S04: Receive and verify the unique code of the material tray. If correct, proceed to the next step; otherwise, indicate a material tray error and re-enter the unique code receiving state. Specific steps can be as follows:

[0077] If the unique code information is received within the set time, proceed to the next step; otherwise, prompt the user to scan the unique code again and return to the previous step.

[0078] Determine if the received unique code information is in the receiving slip. If yes, proceed to the next step; otherwise, prompt that the unique code is not in the receiving slip, rescan the unique code, and return to the previous step.

[0079] S05: Determine whether the unique code of the received tray matches the unique code of the tray already on the rack. Otherwise, proceed to the next step. If it does, indicate that the unique code of the tray is duplicated, light up the indicator, and set the matching tray storage position to the retrievable state.

[0080] S06: Determine whether the material specifications contained in the unique code match the storage location specifications of the rack, and at the same time determine whether there are empty storage locations on the rack. If the material specifications match the storage location specifications of the rack and there are empty storage locations on the rack, proceed to the next step. If the material specifications do not match the storage location specifications of the rack, issue a mismatch prompt and end the current pallet loading process. If there are no empty storage locations on the rack, issue a no-empty-storage-location prompt and end the current pallet loading process.

[0081] S07: Record the unique code and start the countdown to proceed to the next step; specific steps can be as follows:

[0082] Assign a value of 1 to the number of scans.

[0085] S08: Determine whether the storage code of the storage position of the material rack is received before the countdown ends. If yes, proceed to the next step; otherwise, prompt that the racking timeout has occurred and scan the code again to put the racking.

[0086] S09: Record and bind the storage location code and the unique code of the material tray, store them in the valid material loading dataset, prompt that the material tray loading is successful, and decrement the number of empty storage locations on the rack by one.

[0087] By employing the methods and procedures outlined in this application, and utilizing reasonable operational steps and reminder designs, the intelligent sensor rack can smoothly load materials while mitigating a series of potential hidden errors, such as incorrect loading, no available storage space on the rack, trays not being on the receiving slip, occupied storage spaces on the rack, and tray specifications not matching the rack. This ensures that the rack reminders provide accurate and targeted guidance, significantly reducing the risk of errors in the material loading process. This provides a solid and reliable foundation for other processes, reduces the cost of correcting errors for enterprises, and effectively fills a gap in the industry for intelligent sensor racks in this process.

[0088] like Figure 2 As shown, the method also includes determining whether a material tray is placed into the material rack without scanning the barcode. This determination is interspersed throughout the entire material loading process, and the specific steps are as follows:

[0089] After the material loading process begins, monitor the status of each storage location on the material rack;

[0090] When the status of a storage location changes, determine whether there is a material tray in the changed storage location. Otherwise, proceed to the illegal removal process; otherwise, proceed to the next step.

[0091] Read the storage location code of the storage location placed in the material tray, and determine whether the read storage location code belongs to a valid material loading dataset. If it does, determine that the storage location status is normal and end this unscanned barcode placement event; otherwise, determine that the storage location is in an unscanned barcode placement state and proceed to the next step.

[0092] Add the storage code of the unscanned storage location to the exception dataset and indicate that there is a storage location that has not been scanned.

[0093] like Figure 3 and Figure 4 As shown, the method for clearing the "unscanned and placed" status is as follows:

[0094] Remove the "unscanned" status from the storage location:

[0095] Upon receiving the input command to clear the unscanned barcode placement status of the storage location, the process for clearing the unscanned barcode placement status of the storage location begins.

[0096] Receive the rack code of the current rack and read the abnormal dataset corresponding to the rack code;

[0097] Determine if the unscanned and placed status data in the abnormal dataset is empty. If it is, indicate that there is no abnormality in the rack and end the process. Otherwise, indicate that the unscanned and placed tray should be removed and proceed to the next step.

[0098] Monitor the status of each storage location on the material rack;

[0099] Determine whether the unscanned tray has been removed. If yes, proceed to the next step; otherwise, return to the previous step.

[0100] The message indicates that the "unscanned barcode placement" status has been removed, the color of the storage space light has been changed to the normal color, and the corresponding "unscanned barcode placement" status data has been deleted from the abnormal data set.

[0101] Determine if the unscanned barcode placement status data in the abnormal dataset is empty. If yes, proceed to the next step; otherwise, return to the step of monitoring the status of each storage location on the material rack.

[0102] The message indicates that the "unscanned QR code placed" status has been removed, ending the process of removing the "unscanned QR code placed" status.

[0103] like Figure 5 As shown, the shelving process also includes a procedure to handle the unauthorized removal of material trays, specifically including:

[0104] Read the storage location code of the storage location retrieved from the material tray, and determine whether the storage location code belongs to a valid material loading dataset. If yes, proceed to the next step; otherwise, proceed to the unscanned code placement exception resolution process.

[0105] Add the storage location code of the storage location where the material tray is removed and the corresponding unique code of the material tray to the illegal removal dataset. Delete the storage location code of the storage location where the material tray is placed and the corresponding unique code of the material tray from the legal loading dataset. Prompt an illegal removal exception and proceed to the illegal removal exception resolution process.

[0106] like Figure 6 and Figure 7 As shown, the steps to resolve the illegal withdrawal status are as follows:

[0107] Upon receiving the input command to clear the illegal withdrawal status of the storage location, the system enters the illegal withdrawal status clearance process for the storage location.

[0108] Receive the rack code of the current rack and read the abnormal dataset corresponding to the rack code;

[0109] Determine if the illegally retrieved status data in the abnormal dataset is empty. If it is, indicate that there is no abnormality in the rack and end the process. Otherwise, indicate that the illegally retrieved tray should be returned and proceed to the next step.

[0110] Receive and determine whether the unique code of the returned material tray is the unique code of the illegally taken material tray. If it is, prompt the tray to be put back on the shelf and proceed to the next step; otherwise, prompt the tray return error.

[0111] Record the unique code of the material tray and start the countdown;

[0112] Before the countdown ends, determine whether the storage location code of the returned material tray has been received from the storage location on the material rack. If yes, proceed to the next step; otherwise, prompt that the racking timeout has occurred and return to the step of receiving and determining whether the unique code of the returned material tray is the unique code of the illegally retrieved material tray.

[0113] Record the storage location code of the storage location on the bound material rack where the returned material tray is placed, as well as the unique code of the returned material tray, and enter the valid material loading dataset to resolve the illegal retrieval anomaly corresponding to the returned material tray;

[0114] Check again whether the illegally retrieved status data in the abnormal dataset is empty; otherwise, proceed to the step of receiving and checking whether the unique code of the returned material tray is the unique code of the illegally retrieved material tray. If yes, proceed to the next step.

[0115] Determine if there are any abnormalities in the remaining storage locations on the material rack. If so, proceed with the corresponding abnormality handling process; otherwise, indicate that the abnormality has been resolved and end the illegal removal handling process.

[0116] It should be noted that:

[0117] The prompting methods involved in this application include: voice prompts for the material rack, tower lights for the material rack, storage position lights for the material rack, voice prompts for the PDA, and text prompts for the PDA; specific settings can be made according to the specific content of each of the above steps.

[0118] A barcode scanning and shelving notification system for intelligent sensor-operated material racks, such as Figure 8 As shown, the system includes: a system host 10, a material rack 11, and a barcode scanning terminal device 12; the material rack 11 is provided with multiple storage positions 110, and each storage position is provided with a sensing device 111 for sensing the material tray; the barcode scanning terminal device 12 is used for selecting and inputting processing items, and is also used to scan the unique code of the material tray 13 and the material rack code of the material rack 11.

[0119] The system host 10 is used to receive data information from the material rack 11 and the barcode scanning terminal device 12, and execute the barcode scanning and shelving prompt method applied to the intelligent sensing material rack as described above.

[0120] The system applied in this application employs a reasonable design of operating procedures and reminders, ensuring that the intelligent sensor rack can smoothly load materials while avoiding a series of hidden errors such as incorrect material loading, no available storage space on the rack, trays not being on the receiving slip, occupied storage space on the rack, and tray specifications not matching the rack. This allows the rack reminders to truly provide accurate and targeted guidance, significantly reducing the risk of errors in the material loading process of the intelligent sensor rack, providing a solid and reliable foundation for other processes, reducing the cost of correcting errors for enterprises, and effectively filling the industry gap in this process of intelligent sensor racks.
