Description

Technical Field

[0001] The present invention relates to the technical field of intelligent induction material racks, and more particularly to a code scanning and shelving prompting method and system applied to intelligent induction material racks. Background Art

[0002] Smart induction racks are a new type of rack with tray material sensing and detection functions. Each storage location on the rack is usually configured with a storage location code, and a sensor is set on each storage location to read the placed tray. This information is all controlled by a system host. At present, when loading trays on smart induction racks, the prompts usually used are usually set in various ways, without a unified standard, and the set prompts are not comprehensive. The prompts are too simple and cannot provide targeted and effective prompts for the various error situations that may occur during the loading process of smart induction racks. The formal significance of the prompts is far greater than their actual significance. After receiving the error prompt, the operator still needs to check the location of the error according to the internal inspection process.

[0003] Such errors include: wrong material rack for loading (this low-level error is also a common and difficult to detect error, especially when there are many material racks and they are densely distributed), no empty storage space on the material rack, the material tray is not on the receiving list (the receiving list refers to the list of material trays to be loaded on the current material rack. This error is caused by taking the wrong material tray), the storage space on the material rack is occupied (this error is because there is a situation where material tray A is scanned on the material tray, but material tray B is placed on it. This situation is caused by human negligence and is relatively hidden and difficult to detect), the material tray specifications do not match the material rack (the storage space size on the material rack does not match the material tray size), etc. For this reason, a code scanning and shelving prompt method and system for intelligent sensing material racks is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that, in response to the above-mentioned defects of the prior art, a code scanning and shelving prompt method applied to intelligent sensing material racks is provided, and a code scanning and shelving prompt system applied to intelligent sensing material racks is provided.

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

[0006] A method for prompting items to be put on shelves by scanning a code for intelligent induction racks is constructed, wherein the method comprises the following steps:

[0007] Receive and determine whether the rack code is correct. If it is correct, proceed to the next step. Otherwise, it prompts a rack error and re-enters the rack code receiving state;

[0008] Read the current number of empty storage locations on the rack and determine whether it is zero. If it is not zero, proceed to the next step. Otherwise, it will prompt that there are no empty locations on the rack and end the current tray loading process.

[0009] Bind and record the rack code, and prompt to scan the unique code of the tray to be put on the rack;

[0010] Receive and determine whether the unique code of the tray is correct. If it is correct, proceed to the next step. Otherwise, it prompts that the tray is wrong and re-enters the state of receiving the unique code of the tray;

[0011] Determine whether the unique code of the received tray matches the unique code of the tray on the rack. Otherwise, proceed to the next step. If yes, it will prompt that the unique code of the tray is repeated, light up the prompt and set the matching tray storage position to the removable state;

[0012] Determine whether the material specifications contained in the unique code match the storage location specifications of the material rack, and at the same time determine whether there are empty storage locations on the material rack. If the material specifications match the storage location specifications of the material rack and there are empty storage locations on the material rack, proceed to the next step. If the material specifications do not match the storage location specifications of the material rack, a mismatch prompt is given and the current tray shelving process ends. If there are no empty storage locations on the material rack, a no empty storage location prompt is given and the current tray shelving process ends.

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

[0014] Determine whether the storage location code of the material tray storage location on the material rack is received before the countdown ends. If yes, proceed to the next step. Otherwise, it will prompt that the shelf timeout has occurred and re-scan the code to put the material on the shelf;

[0015] Record and bind the storage location code and the unique code of the material tray, store them in the legal loading data center, prompt that the material tray is loaded successfully, and the number of empty storage locations on the material rack is reduced by one.

[0016] The code scanning and shelf prompting method for intelligent induction material racks according to the present invention further comprises:

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

[0018] When the status of the storage location changes, determine whether there is a material tray on the changed storage location. If not, enter the illegal removal processing process. If yes, proceed to the next step.

[0019] Read the storage location code of the storage location where the material tray is placed, and determine whether the read storage location code belongs to the legal material loading data set. If it does, the storage location status is determined to be normal and the event of not scanning the code to put into the material rack is ended. Otherwise, the storage location is determined to be in the state of not scanning the code to put into and proceed to the next step;

[0029] Determine whether the tray that has not been scanned and placed has been taken away. If so, proceed to the next step, otherwise return to the previous step;

[0030] The prompt "not scanned code put in" status is released, and the color of the storage location light is changed to normal color, and the corresponding "not scanned code put in" status data in the abnormal data set is deleted;

[0031] Determine whether the status data of the unscanned code in the abnormal data set is empty. If so, proceed to the next step. Otherwise, return to the step of monitoring the status of each storage location on the material rack;

[0073] Determine whether the received rack code information is correct. If it is correct, proceed to the next step. Otherwise, it prompts that the rack code information is incorrect and returns to the previous step.

[0074] S02: Read the current number of empty storage locations on the rack and determine whether it is zero. If it is not zero, proceed to the next step. Otherwise, it will prompt that there are no empty storage locations on the rack and end the current tray loading process.

[0075] S03: Bind and record the rack code, and prompt to scan the unique code of the tray to be put on the rack;

[0076] S04: Receive and determine whether the unique code of the tray is correct. If it is correct, proceed to the next step. Otherwise, it prompts that the tray is wrong and re-enters the state of receiving the unique code of the tray. The specific steps can be:

[0078] Determine whether the received unique code information is in the material receiving slip. If yes, proceed to the next step. Otherwise, it will prompt that the unique code is not in the material 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. If not, proceed to the next step. If yes, prompt that the unique code of the tray is repeated, light up the prompt and set the matching tray storage position to the material-removable state;

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

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

[0082] Assign 1 to the number of scans;

[0083] Determine whether another unique code is received. If so, add 1 to the number of scans and proceed to the next step. Otherwise, proceed directly to the next step.

[0084] Determine whether the current number of scans is 1. If so, proceed to the next step. Otherwise, it is determined that the material tray has been scanned multiple times and a barcode error is prompted.

[0086] S09: Record and bind the storage location code and the unique code of the material tray, store them in the legal loading data center, prompt the material tray to be loaded successfully, and reduce the number of empty storage locations on the rack by one;

[0087] By applying the method and approach of this application and adopting reasonable operation steps and reminder design, we can ensure that the intelligent sensing material rack can load materials smoothly while avoiding a series of hidden errors such as possible loading rack errors, no empty storage space on the material rack, material tray not included in the material receiving list, storage space on the material rack occupied, material tray specifications not matching the material rack, etc., so that the reminder of the material rack can truly play the actual value of accurate and targeted guidance, greatly reducing the error risk of intelligent sensing material rack in the material shelving link, providing a solid and reliable foundation for other links, reducing the cost of making up for errors for enterprises, and at the same time filling the industry gap of intelligent sensing material rack in this process link.

[0088] like Figure 2 As shown, the method also includes determining whether the material tray is placed in the material rack without scanning the code. This determination is interspersed throughout the entire loading process. The specific steps are:

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

[0090] When the status of the storage location changes, determine whether there is a material tray on the changed storage location. If not, enter the illegal removal processing process. If yes, proceed to the next step.

[0091] Read the storage location code of the storage location where the material tray is placed, and determine whether the read storage location code belongs to the legal material loading data set. If it does, the storage location status is determined to be normal and the event of not scanning the code to put into the material rack is ended. Otherwise, the storage location is determined to be in the state of not scanning the code to put into and proceed to the next step;

[0092] The storage location codes of the storage locations that have not been scanned and placed are added to the abnormal data set, and a prompt is given that there are storage locations that have not been scanned and placed.

[0093] like Figure 3 and Figure 4 As shown, to release the state of not scanning the code, use the following method:

[0094] To cancel the unscanned storage status:

[0095] Receive the input instruction of releasing the state of the unscanned code placed in the storage location, and enter the process of releasing the state of the unscanned code placed in the storage location;

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

[0097] Determine whether the status data of the unscanned tray in the abnormal data set is empty. If so, prompt that there is no abnormality in the rack and end the process. Otherwise, prompt to remove the tray that has not been scanned and enter the next step.

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

[0099] Determine whether the tray that has not been scanned and placed has been taken away. If so, proceed to the next step, otherwise return to the previous step;

[0100] The prompt "not scanned code put in" status is released, and the color of the storage location light is changed to normal color, and the corresponding "not scanned code put in" status data in the abnormal data set is deleted;

[0101] Determine whether the status data of the unscanned code in the abnormal data set is empty. If so, proceed to the next step. Otherwise, return to the step of monitoring the status of each storage location on the material rack;

[0102] It prompts that the status of putting in items without scanning the code has been released, and the process of releasing the status of putting in items without scanning the code is completed.

[0103] like Figure 5 As shown, during the shelving process, there is also a process for handling trays that are illegally taken out, which specifically includes:

[0104] Read the storage location code of the storage location taken out of the material tray and determine whether the storage location code belongs to the legal material loading data set. If yes, proceed to the next step. Otherwise, proceed to the unscanned code placement exception resolution process.

[0105] The storage location code of the storage location where the tray is taken out and the unique code of the corresponding tray are added to the illegal removal data set, and the storage location code of the storage location where the tray is put in and the unique code of the corresponding tray are deleted from the legal loading data set. The system prompts that there is an illegal removal exception and enters the illegal removal exception resolution process;

[0106] like Figure 6 and Figure 7 As shown, the steps to release the illegal withdrawal state are:

[0107] Receive the input instruction of releasing the illegal taking state of the storage location and enter the process of releasing the illegal taking state of the storage location;

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

[0109] Determine whether the illegal removal status data in the abnormal data set is empty. If so, prompt that there is no abnormality in the material rack and end the process. Otherwise, prompt to return the illegally removed material tray and proceed to the next step;

[0110] Receive and determine whether the unique code of the returned tray is the unique code of the tray that was illegally taken out. If yes, prompt to put the tray on the shelf and proceed to the next step. Otherwise, prompt that the tray is returned incorrectly.

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

[0112] Determine whether the storage location code of the storage location where the returned material tray is placed on the material rack is received before the countdown ends. If so, proceed to the next step. Otherwise, prompt the step of shelving timeout 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 taken material tray;

[0113] Record the storage location code of the storage location where the returned tray is placed on the binding material rack and the unique code of the returned tray, and enter it into the legal loading data set to resolve the illegal removal exception corresponding to the returned tray;
