In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The warehouse item management method provided in the embodiment of the present application can be applied in the application environment as shown in FIG. 1, in which a client communicates with a system server through a network to manage the warehouse item. The client is also called the client, which refers to the program that provides local services to the client corresponding to the system server. Clients can be installed on, but are not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The system server can be implemented with a separate server.

The warehouse item management method can be applied to a warehouse management system. The warehouse management system includes a client and a system server shown in FIG. 1 to implement warehouse item management and solve the problem that the location of the warehouse item cannot be updated in real time.

In an embodiment, as shown in FIG. 2, a warehouse item management method is provided. The method is applied to the system server in FIG. 1 as an example, and includes the following steps:

S10: Obtain a timing scan request. The timing scan request includes a timing scan time and a target shelf identifier.

The timing scan request is a request for triggering the system server to scan the items in the warehouse. Scheduled scanning time refers to the time set by the user to periodically scan the items in the warehouse (such as: 0:00 on the 6th of each month, 1:00 of the week, etc.). The target shelf ID is a unique identifier used to identify the target shelf to be scanned. Specifically, the user can set a timing scan time and a shelf identifier to be scanned on the timing scan configuration interface of the client, and trigger a timing scan request to send the timing scan request to the system server, so that the system server obtains the timing scan request .

S20: When it is determined that the current time of the system is a scheduled scanning time, a target RFID antenna corresponding to the target shelf identifier is called, a radio frequency signal sent by the target RFID tag installed on the target item is received, and the radio frequency signal is sent to the RFID reader. The target item is placed on the target shelf corresponding to the target shelf identification.

The current time of the system is the millisecond value obtained by the system server using the current time acquisition method. The current time acquisition method includes, but is not limited to, System.currentTimeMillis (), which can conveniently and quickly obtain the millisecond value of the current time. System.currentTimeMillis () produces a millisecond value for the current time. This millisecond value is the number of milliseconds in real time for the system server. RFID (radio frequency identification) technology is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify target objects and obtain related data. The process does not require manual intervention and can be applied to various harsh environments. An RFID antenna is an inductive antenna used to receive radio frequency signals from a target RFID tag.

A data table is stored in the system server in advance, and the data table stores a shelf identifier and a corresponding RFID antenna identifier. Specifically, a shelf identifier corresponds to an RFID antenna identifier. In this embodiment, the target shelf identifier is the shelf identifier of the target shelf to be scanned by the timing scan request, and the RFID antenna installed on the target shelf corresponding to the target shelf identifier is the target RIFD antenna. If only one target shelf is installed on each target shelf For RFID antennas, each target shelf identifier corresponds to a target RFID antenna. There are N target items placed on each target shelf. Each target item corresponds to a target RFID tag, that is, a unique target RFID tag is installed on each target item. The RFID reader / writer performs wireless communication with the RFID tag through the RFID antenna, and can realize reading or writing of data stored in the RFID tag.

Specifically, the system server judges the current time of the system. When it is determined that the current time of the system is a timed scan time, a target RFID antenna corresponding to the target shelf identifier is called, and the target shelf corresponding to the target shelf identifier is received by the target RFID antenna and placed on the target shelf. A radio frequency signal is sent from a target RFID tag installed on each target item, and the radio frequency signal is sent to the RFID reader via an RFID antenna, so as to achieve the purpose of regularly scanning the warehouse and obtaining the current location information of the warehouse item.

S30: Receive target tag information formed based on the radio frequency signal sent by the RFID reader.

Specifically, the RFID reader has an open reading interface for users to call and read radio frequency signals, obtain target tag information, and transmit the target tag information to the system server through socket communication, so that the system server receives the RFID read and write The target tag information formed based on the radio frequency signal sent by the transmitter. In this embodiment, the target tag information refers to tag information obtained by an RFID reader after reading a radio frequency signal, and the tag information corresponds to a target RFID tag that sends the radio frequency signal. The target tag information specifically includes target tag information including original scan time, antenna identification, and scanned RFID label identification. The original scanning time refers to the time when the target RFID antenna receives the radio frequency signal sent by the target RFID tag. Antenna identification refers to the identification of the target RFID antenna that receives the RF signal and forwards it to the RFID reader. The scanning RFID tag identification refers to the identification of the target RFID tag that sends out the radio frequency signal, that is, the identification of the target RFID tag scanned by this timing scan request.

Two programs on the network exchange data through a two-way communication connection. One end of this connection is called a socket. In this embodiment, the RFID reader and the system server are two ends of the socket, respectively. Specifically, the process for the RFID reader to communicate with the system server through socket communication is as follows: First, a socket (socket) is set in the RFID reader and system server, respectively, and in the socket of the RFID reader Specify the binding port. Specify the system server address and binding port in the socket of the system server. The binding port is the same as the binding port of the RFID reader, so that the RFID reader and system server can communicate through the socket. . Among them, the RFID reader listens for the connection request of the system server by calling the accpet method. The system server sends a connection request to the RFID reader so that the RFID reader receives the connection request and responds to establish a socket connection. After the socket connection is successful, the RFID reader / writer receives the radio frequency signal sent by the RFID antenna to send the target tag information formed based on the radio frequency signal to the system server through the socket, so that the system server can receive the target tag information sent by the RFID reader Because socket communication has the advantages of short data transmission time and high performance, it improves the communication efficiency between the RFID reader and the system server.

S40: Query the database according to the target label information to obtain the corresponding target item information, and store the target item information and the target shelf identifier in the database in association.

Among them, the target article information of each target article in the warehouse is stored in the database in advance. The target item information includes item detailed information and item position information. The item detailed information includes, but is not limited to, item name, item type, item price, and item code. The item location information includes, but is not limited to, a warehouse ID and a shelf ID. The warehouse ID is a unique identifier used to identify the warehouse where the item is located. The shelf ID is a unique identifier for identifying a shelf in a warehouse.

Specifically, the system server queries the database according to the target tag information, obtains target item information (that is, item detailed information and item position information) corresponding to the target tag information, and stores the target item information and the target shelf identifier in the database in association with each other. The process does not need to manually record the item placement positions in the warehouse one by one, which saves manpower, and can regularly update the item placement positions to avoid changes in the position of the items, leading to inconvenience in finding.

In this embodiment, the system server first obtains a timed scan request to make a judgment based on the timed scan time in the timed scan request. If it is determined that the current time of the system is the timed scan time, the call is related to the target shelf identifier in the timed scan request. The corresponding target RFID antenna receives the RF signal from the target RFID tag installed on each target item placed on the target shelf corresponding to the target shelf ID, and sends the RF signal to the RFID reader to scan the warehouse regularly to obtain Purpose of the current warehouse item location information. Then, the system server receives the target tag information formed based on the radio frequency signal sent by the RFID reader via the socket communication technology, so as to improve the communication efficiency between the RFID reader and the system server. Finally, the system server queries the database according to the target tag information to obtain the corresponding target item information, and stores the target item information and the target shelf identifier in the database. This process eliminates the need to manually record the item placement in the warehouse one by one, saving manpower, and Regularly update the position of the items to avoid changes in the position of the items, resulting in inconvenient searching.

In an embodiment, the target tag information specifically includes the target tag information including an original scan time, an antenna identifier, and a scanned RFID tag identifier.

The scanning RFID tag identification refers to the identification of the target RFID tag that sends out the radio frequency signal, that is, the identification of the target RFID tag scanned by this timing scan request.

After step S30, that is, after receiving the target tag information obtained based on the radio frequency signal sent by the RFID reader, the warehouse item management method further includes the following steps: according to the original scan time and the antenna identification, the RFID will be scanned Tag identification associations are stored in the database.

Specifically, when the system server receives the target tag information sent by the RFID reader through socket communication, it stores the target tag information in association with the original scan time and the antenna identifier, that is, the RFID tag is scanned according to the original scan time and the antenna identifier. The ID is stored in the database in association, so that subsequent users can select based on the two fields of the original scan time and the antenna ID to query the corresponding scanned RFID tag ID, which is the target scanned by this scheduled scan request. The identification of the item's target RFID tag. Understandably, in each target tag information received by the system server, the target item corresponding to the scanned RFID tag identification is placed on the target shelf during the current scan based on the timing scan request to achieve the position of the target item. Positioning.

In an embodiment, as shown in FIG. 3, the warehouse item management method further includes the following steps:

S51: Acquire a user query request. The user query request includes a target antenna identifier and a target scanning time.

The user query request is a request for triggering the system server to query the database based on the query conditions. Specifically, a query box is displayed on the query interface of the warehouse management system for the user to select and enter the required query conditions. The query display box includes, but is not limited to, two query conditions, namely, the antenna identification and the scanning time. Select the antenna ID and the original scan time to query the data, so that the system server obtains the user query request based on the target antenna ID and the target scan time selected by the user. Further, the system server will also display a recommendation item in the query box. This recommendation item refers to the query condition that has been ranked in the top N digits of the number of queries in the most recent period (pre-set by the developer), so that the user can directly click and enter No need to manually enter or select query conditions, saving time.

S52: Find a database based on the target antenna identification and the target scanning time, and obtain a historical RFID tag identification corresponding to the target antenna identification and the target scanning time.

The historical RFID tag identification refers to the scanned RFID tag identification stored in the database and corresponding to the target antenna identification and the target scanning time. The scanned RFID tag identifier is an identifier of a target RFID tag based on a target item scanned by each timing scan request in history. The scanned RFID tag identifier is stored in a database in association with the antenna identifier according to the original scan time. Specifically, the system server searches for a database based on the target antenna identification and the target scanning time, and obtains a historical RFID tag identification corresponding to the target antenna identification and the target scanning time for subsequent analysis based on the historical RFID tag identification.

S53: Based on the target antenna identification and the current time of the system, obtain a scanned RFID tag identification corresponding to the target antenna identification and the current time of the system.

Specifically, the system server obtains the scanned RFID tag identifier corresponding to the target antenna identifier and the current time of the system based on the query conditions of the target antenna identifier and the current time of the system for subsequent analysis based on the scanned RFID tag identifier.

S54: Obtain inventory change information based on historical RFID tag identification and scanning RFID tag identification.

Among them, the inventory change information history information changes between the RFID tag identification and the scanned RFID tag identification. Specifically, the system server performs analysis based on historical RFID tag identifications and scanned RFID tag identifications, that is, analyzing the floating between historical RFID tag identifications and scanning RFID tag identifications to obtain inventory change information, make timely adjustments, and reasonably control inventory. Conducive to the production and operation activities of enterprises.

In this embodiment, the system server obtains a user query request to find a database based on the target antenna identifier and the target scan time in the user query request, and obtains a historical RFID tag identifier corresponding to the target antenna identifier and the target scan time; and then based on the target antenna identifier And the current time of the system, obtain the scanned RFID tag identification corresponding to the target antenna identification and the current time of the system, so that the system server can obtain inventory change information based on historical RFID tag identification and scanned RFID tag identification, make timely adjustments, and reasonably control inventory, Conducive to the production and operation activities of enterprises.

In an embodiment, after step S40, that is, after the step of associating the target item information and the target shelf identifier in a database, as shown in FIG. 4, after step S40, the warehouse item management method further includes the following steps:

S61: Based on the target shelf identifier, perform quantity statistics on the target items placed on the target shelf corresponding to the target shelf identifier, and obtain a statistical result.

Among them, the statistical result refers to the number of target items on the target shelf. Specifically, the system server counts the number of target items placed on the target shelf corresponding to the target shelf identifier based on the target shelf identifier, and specifically collects target label information corresponding to the target shelf identifier to obtain corresponding statistical results.

Further, each shelf ID corresponds to an item category. After the system server obtains the scanned RFID tag ID corresponding to each shelf ID, it will query the database based on the scanned RFID tag ID to determine whether the item category corresponding to the scanned RFID tag ID is related to The item category corresponding to the shelf ID matches. If the match is successful, the position is correct. If the match fails, the item is placed in the wrong position. The abnormal position information is generated and sent to the client corresponding to the warehouse administrator ID. Monitor the purpose of storing items in the warehouse. The client corresponding to the warehouse administrator ID is a pre-configured email address for receiving the generated location exception information.

S62: The statistical result is dynamically marked on the target shelf corresponding to the target shelf ID in the electronic map of the warehouse.

The electronic map of the warehouse is a pre-created electronic map. The electronic map of the warehouse includes a target shelf identifier and a corresponding target shelf point, and the target shelf point is a display position of the target shelf on the warehouse electronic map. Specifically, after acquiring the statistical result of the target RFID tag information corresponding to each target shelf identifier, the system server dynamically marks the statistical result to the target shelf point corresponding to the target shelf identifier in the electronic map of the warehouse for intuitive display. The number of items per shelf, that is, the inventory.

In this embodiment, based on the target shelf identifier, the system server counts the number of target items placed on the target shelf corresponding to the target shelf identifier, and obtains the statistical result, so as to dynamically mark the statistical result into the warehouse electronic map corresponding to the target shelf identifier. Target shelves, so that the number of items in each shelf can be visually displayed for easy viewing.

In an embodiment, as shown in FIG. 5, in step S61, the target items placed on the target shelf corresponding to the target shelf identifier are counted, and the statistical result is obtained, which specifically includes the following steps:

S611: Count the number of target items placed on the target shelf corresponding to the target shelf identifier according to the item category corresponding to each target item, and obtain a statistical result corresponding to each item category.

Specifically, the scanned RFID tag identification of each target item placed on the same shelf corresponds to the same item category, that is, each shelf places items of the same category, so as to achieve a reasonable placement of the warehouse. The system server queries the database based on the scanned RFID tag IDs in the target tag information to obtain the item category corresponding to each target tag information and classify the target articles. The target articles matching the same category are based on the corresponding target RFID tag information. Scan the RFID tag identification for quantity statistics to obtain the statistical results corresponding to each item category, so that the subsequent statistical results corresponding to each item category can be judged.

S612: If the statistical result corresponding to each item category is lower than the warning line corresponding to the item category, abnormal reminder information is generated.

Among them, an early warning line corresponding to each item category is set in the system in advance, and the early warning line is a minimum quantity of each category of goods set to prevent tight inventory. Specifically, the system server judges the number of scanned RFID tag identifications in the target tag information corresponding to each item category. If the number of scanned RFID tag identifications of any item category is lower than the warning line corresponding to the item category, An exception alert message is generated. The abnormal reminder information includes inventory increase information and inventory increase location information in order to increase the inventory in time. Inventory increase information is information that reminds the user which item category needs to increase inventory. The inventory increase position information is information of an increased inventory item placement position.

Further, the system server will find N shelf identifiers (N is a positive integer greater than 1) corresponding to the same item category below the early warning line, and count the number of items of the target item placed on the shelf corresponding to each shelf identifier. The quantity of the item is compared with the storage capacity of the shelf. If the quantity of the item is less than the storage capacity of the shelf, the corresponding shelf is regarded as a newly placed shelf. Save time by placing new items directly on shelves that have not reached the shelf storage capacity. The shelf storage quantity refers to the maximum storage quantity of each shelf. The new display shelf is the shelf on which new inventory items are placed. In this embodiment, the newly added shelf adds location information to the inventory.

Correspondingly, after acquiring the abnormal reminder information, step S62 of the warehouse item management method is specifically: dynamically marking the statistical result on the target shelf corresponding to the target shelf identifier in the electronic map of the warehouse, and the item category corresponding to the abnormal reminder information Highlighted.

Specifically, after acquiring the number of scanned RFID tag identifiers of each item category, that is, the statistical result, the system server dynamically marks the statistical result on the target shelf corresponding to the target shelf identifier in the electronic map of the warehouse, and corresponds to the abnormal reminder information. The item categories are marked prominently, that is, based on the inventory increase information and inventory increase location information, the target shelf corresponding to the item category below the early warning line and the number of target items on the shelf is lower than the target shelf storage amount (i.e. the current shelf In the shelf where new items corresponding to the item category corresponding to the reminder information can be placed), highlighting is performed, so that the user can intuitively see which shelf can hold newly added inventory items.

In this embodiment, the system server counts the number of target items placed on the target shelf corresponding to the target shelf identifier according to the item category corresponding to each target item, and obtains a statistical result corresponding to each item category. Then, the server judges the statistical result corresponding to each item category. If the statistical result corresponding to each item category is lower than the warning line corresponding to the item category, it generates abnormal reminder information, that is, inventory increase information and inventory increase location information, so that Based on the inventory increase information and inventory increase location information, determine the item category of the newly added inventory item and the placement location of the newly added inventory item. In addition, the server also highlights the target shelf in the electronic map of the warehouse, so that the user can intuitively see which shelf can hold the newly added inventory items and increase the inventory in time.

In an embodiment, as shown in FIG. 6, before step S10, the warehouse item management method further includes the following steps:

S71: The RFID antenna identifier is stored in association with the corresponding target shelf identifier, and the target shelf identifier corresponds to a target shelf.

Specifically, an RFID antenna is installed on each shelf, each RFID antenna ID corresponds to an RFID antenna, and each target shelf ID corresponds to a target shelf, so that the system service weapon stores the RFID antenna ID and the corresponding target shelf ID in association with each other. For example, the A antenna corresponds to the target A shelf, and the B antenna corresponds to the target B shelf. Among them, the signals between each RFID antenna do not affect each other (metal isolation can be used, such as: metal isolation between shelves and shelves, RFID antennas are inside each shelf, so that the signals received by each RFID antenna are from Inside each shelf so that the signals between each RFID antenna do not affect each other) to achieve comprehensive coverage of the warehouse.

S72: Generate a unique ID for each target item placed on the target shelf, and write the unique ID into the RFID tag to obtain the target RFID tag ID corresponding to each target item.

Wherein, at least one target item is placed on each target shelf. The target RFID tag identification is an index used to record the target RFID tag in the database. Specifically, the system server generates a unique identifier for each target item placed on the target shelf, and writes the unique identifier into the RFID tag through a write interface opened by the RFID reader to obtain each target item. Corresponding target label information. The method of generating a unique identifier may be UUID (Universally Unique Identifier, universal unique identifier). UUID refers to a number generated on a machine, it is guaranteed to be unique to all machines in the same space and time, to ensure the uniqueness of each target RFID tag identification, improve the accuracy of the statistical results of warehouse items, and improve the warehouse The accuracy of item statistics results.

In this embodiment, the system server first stores the RFID antenna identifier and the corresponding target shelf identifier in association, so as to generate a unique identifier for each target item placed on the target shelf corresponding to the target shelf identifier, and write the unique identifier to In the RFID tag, target tag information corresponding to each target item is acquired to ensure the uniqueness of each target RFID tag identification.
