[0033] like Figure 1As shown, Figure 1 This is a flow chart of a warehouse management method based on RFID electronic tags according to an embodiment of the present invention;

[0034] Reference Figure 1 The embodiment of the present invention proposes a warehouse management method based on RFID electronic tags, which is applied to a warehouse management platform and includes the following steps:

[0035] S10: receiving a cargo storage request, determining a storage area and a corresponding first information reading and writing device, and allocating a storage shelf at one time, wherein the first information reading and writing device is installed in the storage area;

[0036] When the warehouse management platform receives a cargo storage request, it parses the cargo information in the cargo storage request, determines the corresponding warehousing area according to the cargo information, obtains the first information reading and writing device in the warehousing area, and allocates warehousing shelves for the cargo.

[0037] As a preferred embodiment, before receiving the cargo storage request, the method includes:

[0038] The second information reading and writing device on the mobile device is started to identify the cargo information stored in the cargo electronic tag, and a cargo storage request is generated and sent to the storage management platform.

[0039] The mobile device is used to load and move goods, and the goods storage request carries the goods information. The second information reading and writing device is used to quickly complete the entry of goods information, so that the warehouse management platform can quickly determine the corresponding storage area, storage shelf and first information reading and writing device of the goods to ensure the storage rhythm.

[0040] As a preferred embodiment, after receiving a cargo storage request, the current location of the mobile device and the location of the storage shelf are obtained, a navigation route for cargo storage is planned, and the route is sent to a terminal associated with the mobile device.

[0041] After receiving the cargo storage request, the warehouse management platform plans a navigation route for the mobile device and guides the mobile device to move to the storage shelf location. If the mobile device is manually pushed, the terminal associated with the mobile device can be the terminal used by the worker. If the mobile device is an automated loading and unloading device, such as a robot, the navigation route is sent to the robot controller.

[0042] S20: in response to the signal that the mobile device has arrived at the storage area, the first information reading and writing device is activated to identify the electronic tag of the goods on the mobile device;

[0043] As a preferred embodiment, the first information reading and writing device is installed on a central shelf at the center of the storage area, and the reading and writing range of the first information reading and writing device is the area formed by the aisles around the central shelf.

[0044] The area formed by the shelves surrounding the central shelf with the center of the storage area as the center is the range for the first information reading and writing device to identify the electronic tags of goods. Specifically, the first information reading and writing device can identify the electronic tags of goods on the mobile devices passing through the aisles around the central shelf.

[0045] There are four shelves distributed around the central shelf, and the storage shelf can be the central shelf and the four shelves around the central shelf. For example, after the storage shelf of the goods is determined, the mobile device enters the storage area and is recognized by the first information reading and writing device.

[0046] As a preferred embodiment, the reading and writing range of the first information reading and writing device is the storage area formed by the 3*3 matrix shelves and the surrounding aisles. The first information reading and writing device with a suitable reading and writing range is selected according to factors such as shelf size and floor space.

[0047] In a specific example, the first information reading and writing device and the second information reading and writing device are RFID readers and writers.

[0048] More preferably, an ultra-high frequency RFID reader is used. An ultra-high frequency RFID reader usually has a long reading and writing range, which can reach several meters or even more than ten meters. It can be used in application scenarios where a large number of tags need to be read quickly or tags need to be read at a long distance.

[0049] At the same time, the first information reading and writing device and the second information reading and writing device read the electronic tag of the goods to ensure that the transmission of the goods information is not lost. In cooperation with the first information reading and writing device, the electronic tag information of the goods identified by the first information reading and writing device is consistent with the electronic tag information of the goods identified by the second information reading and writing device, thereby verifying whether the storage shelf has been changed.

[0050] As a preferred embodiment, the signal that the mobile device arrives at the storage area includes one or more of the current moving time of the mobile device reaching a preset time, the current moving displacement reaching a preset displacement, and the current position being within a set range.

[0051] The warehouse management platform can analyze and determine whether the mobile device has arrived at the warehousing area or whether it has arrived near the warehousing area based on the current moving time of the mobile device reaching the preset time, the current moving displacement reaching the preset displacement, and the current position being within the set range, so as to activate the first information reading and writing unit to identify the electronic tag of the goods.

[0052] S30: re-allocating the incoming shelves according to the goods electronic tags; if the corresponding incoming shelf information has not changed, controlling the signal device on the incoming shelf to start;

[0053] As a preferred embodiment, Figure 2 As shown, the secondary allocation of the goods to the storage shelves according to the goods electronic tags includes:

[0054] S301: Determine whether the secondarily allocated storage shelf matches the firstly allocated storage shelf;

[0055] S302: If they match, it is determined that the incoming shelf information has not been changed;

[0056] S303: If the match fails, determine the change of the incoming shelf information.

[0057] The cargo electronic tag stores cargo information. After the first information reading and writing device recognizes the information of the cargo electronic tag, the cargo information and the device information of the first information reading and writing device are sent to the warehouse management platform. The warehouse management platform reallocates / confirms the storage shelf according to the cargo information.

[0058] At this time, the warehouse management platform executes the judgment logic of the change of the incoming shelf information. Specifically, it determines whether the incoming area is consistent with the incoming area determined for the first time according to the device information of the first information reading and writing device, and verifies whether the incoming shelf allocated for the second time matches the incoming shelf allocated for the first time. If the incoming areas are consistent, and / or the incoming shelves match, indicating that the incoming shelf information has not changed, the goods can be put on the shelves. If the incoming shelves do not match, or the incoming areas are inconsistent, the goods cannot be put on the shelves, and it is necessary to wait for the warehouse management platform to re-plan.

[0059] As a preferred embodiment, after determining that the storage shelf information has changed, the new storage shelf and the storage area where it is located are determined, and the first information reading and writing device is reselected and determined, and the navigation route is replanned.

[0060] As a preferred embodiment, the signal device includes at least one of a signal light and a voice prompt.

[0061] When the warehouse management platform verifies that the incoming shelf information of the goods has not changed, the signal device is activated to remind the mobile device or workers to re-verify the incoming shelf to avoid the problem of manual rework and adjustment due to the inconsistency between the incoming shelf where the goods are stored and the preset incoming shelf. At the same time, the signal device is activated to send a reminder signal to facilitate the rapid determination of the incoming shelf location and improve storage efficiency.

[0062] S40: receiving the goods on-shelf information, and updating the goods storage information in the goods electronic tag through the first information reading and writing device.

[0063] As a preferred embodiment, the goods on-shelf information includes: sensor change information on the incoming shelves and sensor change information on the mobile device.

[0064] When the warehouse management platform detects changes in the incoming shelves and / or sensor information on the mobile device, indicating that the goods are stored on the incoming shelves, the goods storage information in the goods electronic tags is updated in a timely manner, which is conducive to the subsequent inventory location verification process and traceability. The goods storage information includes the mapping relationship between the goods information and the incoming shelf information.

[0065] As a preferred embodiment, the cargo storage information in the cargo tag can also be updated through the second information reading and writing unit. The second information reading and writing unit is installed on the mobile device. In some scenarios, the second information reading and writing unit is closer to the cargo than the first information reading and writing unit, which is convenient for writing cargo storage information.

[0066] After receiving the cargo storage request, the storage management platform of this embodiment determines the storage area and the corresponding first information reading and writing device for the cargo to be stored, and allocates the storage shelves once. In response to the signal that the mobile device arrives at the storage area, the first information reading and writing device is started, the cargo electronic tag on the mobile device is identified, and the storage shelves are allocated again according to the cargo information in the cargo electronic tag. If the corresponding storage shelf information is not changed after verification, the signal device on the storage shelf is controlled to start to instruct the mobile device or manual to put the cargo on the storage shelf, and the cargo storage information in the cargo electronic tag is updated through the first information reading and writing device after receiving the cargo shelving information. This embodiment verifies twice that the cargo storage shelf information has not changed before the cargo arrives at the storage area and is not put on the shelf, and uses the signal device on the storage shelf to re-determine the storage shelf location information to ensure that the cargo inventory location is consistent with the preset inventory location, avoid manual rework and adjustment, and ensure the storage rhythm.
