[0038] The following description, in conjunction with the accompanying drawings, illustrates a method for managing stored goods provided by an embodiment of the present invention.

[0039] like Figure 2 As shown, this embodiment of the invention provides a method for managing stored goods, which may include, but is not limited to: Step S1: Obtain the warehousing instruction transmitted by the handheld terminal. The warehousing instruction includes the item EPC code obtained by scanning the RFID tag of each warehousing item and the shelf EPC code obtained by scanning the shelf location reference tag. Generate or update the file information of the warehousing item according to the warehousing instruction and store it.

[0040] In specific implementation, in addition to using EPC codes, this invention can also use QR codes or other identification codes that can be assigned a unique ID, and is not limited here.

[0041] In the specific implementation process, the handheld terminal in the embodiments of the present invention is preferably an industrial-grade PDA (handheld computer). Of course, other similar alternatives can also be used, which are not limited here.

[0042] In one feasible implementation, the step of generating or updating and storing the file information of the inbound items according to the inbound instruction in this embodiment of the invention may include, but is not limited to: Traverse the archive to find if there is any archive information that matches the EPC code of the item; If so, update and store the file information of the items that have been put into storage; If not, generate and store the file information for the items to be put into storage.

[0043] In the specific implementation process, when there is file information in the archive that matches the EPC code of the item, it indicates that the item currently being stored is an item that has been borrowed and returned. When the item is stored, the file information of the item is updated and stored. The updated file information may include, but is not limited to, the storage time, storage location information, and storage status information.

[0044] When there is no file information in the archive that matches the EPC code of the item, it indicates that the item currently being stored is a new item. After the item is stored, a permanent file is created for the item, recording the item's EPC code and the shelf EPC code of the item's storage location. At the same time, the storage status of the item is initialized, such as "on shelf".

[0045] Step S2: Obtain the search instruction transmitted by the handheld terminal. The search instruction includes information about the item to be searched. Generate the location information and navigation path of the item to be searched based on the information about the item to be searched, and push them to the handheld terminal.

[0046] In one feasible implementation, the step of generating the location information and navigation path of the item to be found based on the item information in this embodiment of the invention may include, but is not limited to: Based on the information of the item to be found, the file information of the item to be found is retrieved, the shelf location EPC code in the file information is extracted, the storage shelf of the item to be found is determined based on the shelf location EPC code, and the location information and navigation path of the storage shelf are generated.

[0047] In the specific implementation process, since the item to be searched (such as a book) may have been checked out, the embodiments of the present invention may include, but are not limited to, the following steps before retrieving the shelf location EPC code from the file information: The storage status in the file information is identified. If the storage status is "borrowed", the status information of the item to be searched is generated and pushed to the handheld terminal as a prompt.

[0048] In one feasible implementation, after generating the location information and navigation path of the item to be found based on the item information and pushing it to the handheld terminal, the present invention may, but is not limited to, further include: The connection status between the handheld terminal and the RFID tag of the item to be located is acquired in real time. If the handheld terminal does not establish a connection with the RFID tag, the handheld terminal is controlled to operate at a first preset power. If the handheld terminal establishes a connection with the RFID tag, the handheld terminal is controlled to work at a second preset power; The first preset power is greater than the second preset power.

[0049] In the specific implementation process, when the handheld terminal does not establish a connection with the RFID tag, it indicates that the handheld terminal is far away from the to-be-searched-for article, at this time, the handheld terminal is controlled to work at the first preset power (high power mode), which can expand the communication range and realize fast and large-range search; after the handheld terminal establishes a connection with the RFID tag, it indicates that the handheld terminal is close to the to-be-searched-for article, at this time, the handheld terminal is controlled to work at the second preset power (low power mode), which performs fine search in a small range.

[0050] The embodiment of the application can obviously reduce the power consumption of the handheld terminal and prolong the working time of the handheld terminal after single charging by dynamically regulating the power of the handheld terminal.

[0051] Step S3: obtaining the delivery instruction transmitted by the handheld terminal, changing the archive information of the delivery article according to the delivery instruction, and recording the associated information of the delivery instruction.

[0052] In the specific implementation process, the associated information in the embodiment of the application can include but is not limited to the delivery time, the borrower and other related information, which is not limited here.

[0053] Step S4: periodically traversing each shelf, identifying whether the archive information of each storage article is wrong, and if so, triggering a verification alarm.

[0054] In the specific implementation process, the embodiment of the application can but not limited to set a fixed reader-writer in the warehouse, and the fixed reader-writer periodically scans the articles on the shelf and identifies whether the archive information of each storage article is wrong.

[0055] In a feasible implementation scheme, the identification of whether the archive information of each storage article is wrong in the embodiment of the application, if so, triggering a verification alarm, can but not limited to include: If the storage state information in the archive information is wrong, the verification alarm information is pushed to the verification end in real time.

[0056] In the specific implementation process, the error of the storage state information may be that the information is not entered when the article is borrowed and returned, resulting in the state showing "borrowed", while the article entity is in the warehouse, at this time, the real-time situation is pushed to the verification end to remind the verification end to verify in time.

[0057] In an implementable embodiment, the present embodiment triggers a verification alarm if the profile information of each storage item is found to have errors, which can include but is not limited to the following: If the shelf information in the profile information has errors, the shelf information of the storage item is updated, and the update record is recorded and periodically pushed to the verification end.

[0058] In the specific implementation process, the errors in the shelf information can be errors in the placement after the entry of the item information. For such errors, the shelf information of the storage item can be re-updated, and the update record is recorded and then periodically (such as once a month) pushed to the verification end for periodic verification by the verification end.

[0059] The warehouse item management method provided by the present embodiment realizes transparent management of the whole life cycle from item warehousing, inventory to destruction, and any movement has a trace, which greatly reduces the risk of loss.

[0060] Further, the present embodiment converts the blind search mode of "people looking for items" into the intelligent mode of "system guiding people" by generating the location information and navigation path of the item to be found according to the item information to be found and pushing them to the handheld terminal, which greatly shortens the search time and improves the work efficiency.
