In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.

FIG. 1 is a schematic diagram of a warehouse management system according to an embodiment of the present invention.

1, the warehouse management system 100 includes a plurality of identification antennas, a plurality of RFID landmarks 171, 172, 173, a database 120, a server host 110, and a mobile device 160, wherein the server host 110 is coupled to the plurality of identification antennas, the database 120 and mobile device 160. In some embodiments, the plurality of identification antennas of the warehouse management system 100 include landmark antennas 131 , cargo antennas 132 , and personnel antennas 133 , all of which are disposed at different positions on the transport equipment 200 (eg, a forklift) used to transport goods. However, the present invention is not limited to this, and those skilled in the art who apply the present invention can add other identification antennas to specific positions according to their needs.

In detail, a plurality of RFID landmarks 171 , 172 , 173 are set in a warehouse, for example, to locate a plurality of specific locations of the warehouse, such as a specific road, a specific corner, or a specific storage location, and so on. It must be noted that although three RFID landmarks 171 , 172 and 173 are exemplarily shown in FIG. 1 , the present invention does not limit the number of RFID landmarks and their setting positions in the warehouse. Those with ordinary knowledge in the art It can be implemented according to their needs. In addition, the RFID landmark can be set on the floor, road or ceiling of the warehouse, etc., and the present invention is not limited thereto. The landmark antenna 131 on the transportation device 200 is set corresponding to the RFID landmarks 171 , 172 , and 173 , so that the landmark antenna 131 can identify the RFID landmarks 171 , 172 , and 173 when the transportation device 200 passes through a specific location where the RFID landmarks 171 , 172 , and 173 are located.

On the other hand, goods entering and leaving the warehouse are provided with goods labels to provide relevant information of the goods. For example, the goods label provides information including goods type, quantity, and current progress (for example, material has been picked, stocked or picked), etc., but the invention is not limited to this. The cargo antenna 132 on the shipping device 200 is configured to identify the cargo tags of the cargo being handled by the shipping device 200 . In some embodiments, the cargo antenna 132 also has the function of writing the RFID tag, which can write the current progress of the cargo into the cargo tag or rewrite the existing current progress in the cargo tag.

Additionally, in some embodiments, personnel tags are also worn by workers in the warehouse. The personnel antenna 133 on the transport equipment 200 is configured to identify the worker operating the transport equipment 200 .

The identification results obtained by the identification antennas (including the landmark antenna 131 , the cargo antenna 132 and the personnel antenna 133 ) will be transmitted to the server host 110 . In some embodiments, one or more RFID readers 140 and a communication device 150 are disposed on the transport device 200 . The RFID reader 140 is used to control all identification antennas on the conveying equipment. For example, one RFID reader 140 can control up to thirty-two identification antennas. After the RFID reader 140 obtains the data from the identification antenna, for example, the data is transmitted to the server host 110 through the communication device 150 . However, the present invention does not limit the specific means by which the identification antenna transmits the identification result to the server host 110 .

The database 120 is used to record the inventory status of all goods in the warehouse, and the server host 110 is used to manage and maintain the database 120 according to the identification result of the identification antenna, and to instruct the on-site operators through the mobile device 160 .

In some embodiments, the server host 110 can know what the cargo is being transported by the transport device 200 according to the identification result of the cargo antenna 132 . In some embodiments, while knowing what the transport device 200 is carrying, if the server 110 receives the identification result of the personnel antenna 133 at the same time, the server 110 can know that the transport device 200 is currently operating to transport the cargo. cargo operator. In some embodiments, while knowing what the cargo is being transported by the transportation device 200, if the server host 110 receives the identification result of the landmark antenna 131 at the same time, the server host 110 can know the travel route and location of the cargo .

Accordingly, as long as the identification antenna on the transport device 200 can transmit its identification result to the server host 110 at any time, the server host 110 can know all the movements of the transport device 200 transporting the goods in the warehouse, and can also know that the goods are in the warehouse Inventory status changes in . Therefore, the server host 110 can determine the current progress of the goods (for example, determine whether the goods are currently picked, put into storage, or have been picked, etc.) according to the identification result of the identification antenna, and manage the inventory status of the goods in the database 120 .

In some embodiments, the server host 110 can also determine the current status of the goods, such as the current operating status, etc., according to the identification result of the identification antenna. For example, the servo host 110 can determine whether the goods being transported by the transport device 200 need to be transported and where they need to be transported according to the identification result of the identification antenna. Further, the server host 110 also transmits the above-mentioned operation state to the mobile device 160, such as a smart phone or a tablet computer. In this way, the mobile device 160 can display the current operation status of the goods, so that the operator who operates the conveying equipment 200 can know how to operate the goods. In order to prevent the situation that the network is disconnected and cannot be operated, in other embodiments, the RFID reader 140 can be added to an embedded system instead of the server host 110 to determine the current status of the goods according to the identification result of the identification antenna, and temporarily store the data. stored in the RFID reader 140 . After the network environment is restored, the temporary data is uploaded to the server host 110 and the database 120 is updated at the same time.

FIG. 2 is a flowchart of a warehouse management method according to an embodiment of the present invention.

The embodiment of FIG. 2 is applicable to the warehouse management system 10 of the embodiment of FIG. 1 . Please refer to FIG. 1 and FIG. 2 at the same time, in step S110, the server host 110 will first receive the identification results of the plurality of identification antennas, and then in step S120 will determine the current progress and The inventory status of goods in the database 120 is managed. The implementations of step S110 and step S120 have been illustrated in the above-mentioned relevant paragraphs of FIG. 1 , and thus will not be repeated here. Several embodiments will be introduced below to exemplarily illustrate how to apply the warehouse management system and warehouse management method of the present disclosure to manage warehouses.

FIG. 3 is a flow chart of picking materials in a warehouse management method according to an embodiment of the present invention. The embodiment of FIG. 3 is applicable to the warehouse management system 10 of the embodiment of FIG. 1 , so the embodiment of FIG. 3 will be described below with reference to each device of the embodiment of FIG. 1 .

In the embodiment of FIG. 3 , the process of obtaining the goods from the current location of the goods (for example, the first storage location outside the warehouse) by the delivery device 200 is described.

Please refer to FIG. 1 and FIG. 3 at the same time. First, in step S210 , a plurality of identification antennas are identified at the same time, and the identification results are transmitted to the server host 110 . In this embodiment, the landmark antenna 131 , the cargo antenna 132 and the personnel antenna 133 are identified simultaneously, and the identification results are transmitted to the server host 110 .

In step S220, the cargo antenna 132 reads the cargo tag. In this embodiment, as long as any cargo tag enters the reading range of the cargo antenna 132, the cargo antenna 132 will read the cargo tag. However, the cargo antenna 132 reading the cargo tag does not indicate that the cargo corresponding to the cargo tag is being transported by the transport device 200 . Therefore, one feature of the present invention is to provide a technical means to reduce the misjudgment rate of cargo handling.

In step S230, the server host 110 determines whether the reading condition of the cargo label is satisfied. Specifically, the condition for reading the cargo label refers to the condition that the cargo corresponding to the cargo label is indeed being transported by the transport device 200 . In this embodiment, the cargo antenna 132 reads at a specific frequency, and the condition for reading the cargo label includes continuously identifying the cargo label for a predetermined number of times (such as but not limited to, 30 seconds) within a preset time. limited to 5 times). In other words, as long as the cargo antenna 132 continues to recognize the cargo label for more than the preset number of times within the preset time, the server host 110 will determine that the reading condition of the cargo label has been satisfied. In some embodiments, the reading condition of the cargo tag further includes that the personnel antenna 133 recognizes the operator at the same time. In other words, in addition to the fact that the goods are actually placed on the transport equipment 200, the transport equipment 200 also needs to be operated by an operator to satisfy the conditions for reading the goods labels.

It is worth mentioning that, generally, if the cargo antenna 132 misreads the cargo label, the probability of failure when the cargo antenna 132 encodes and writes the data into the misread cargo label is high. Therefore, in some embodiments, after reading the cargo label, the cargo antenna 132 will attempt to encode the test data (eg, the current progress of the cargo) correspondingly and write it into the cargo label. If the servo host 110 determines that the cargo antenna 132 has continuously identified the cargo tag for more than a preset number of times within the preset time, the personnel antenna 133 has identified the operator at the same time, and the cargo antenna 132 has successfully written the test data into the cargo tag. It is judged that the reading condition of the cargo label has been satisfied.

If the server host 110 determines that the reading condition of the cargo label is not satisfied, the process returns to step S210. On the contrary, if the server host 110 judges that the reading condition of the cargo label has been satisfied, it proceeds to step S240.

In this embodiment, the server host 110 determines the current status of the goods according to the goods labels. For example, the server host 110 knows that the first cargo needs to be picked but has not yet been picked, so when the label of the cargo corresponds to the first cargo, the server host 110 will determine that the current state of the first cargo is the picking state; the server host 110 It is known that the second item has been picked but has not been put into the warehouse, so when the label of the goods corresponds to the second item, the server host 110 will determine that the current state of the second item is the in-stock state; the server host 110 knows that the third item has been put into the warehouse, so When the cargo label corresponds to the third cargo, the servo host 110 determines that the current state of the third cargo is the picking state. In step S240, the server host 110 determines that the current status of the goods is the picking status according to the goods label.

In step S250, the mobile device 160 displays the operation state of "waiting to pick". In this embodiment, the server host 110, for example, transmits the current status of the goods (for example, the picking status) to the mobile device 160, and the mobile device 160 displays the operation status (for example, waiting for picking) according to the current status of the goods , to indicate how the cargo should currently be handled.

In step S260, the server host 110 determines whether the operator identified by the personnel antenna 133 is correct according to the cargo label. In some embodiments, picking operations for each type of cargo may have operator restrictions. For example, the operators in charge of each kind of goods may be different, or certain goods may require operators with specific permissions to be able to pick materials, etc. Therefore, the server host 110 determines whether the operator identified by the personnel antenna 133 has the authority to pick up the goods corresponding to the goods label according to the goods label.

If the server host 110 determines that the worker identified by the worker antenna 133 is correct, the process proceeds to step S270. On the contrary, if the server host 110 determines that the operator identified by the personnel antenna 133 is incorrect, the process proceeds to step S280.

In step S270, the mobile device 160 displays the operation status of "Pickup Completed". In the present embodiment, when the mobile device 160 displays the operation status of “receiving completed”, it indicates that the goods corresponding to the goods labels are indeed being transported by the transport equipment 200 , and the transport equipment 200 is being identified by the personnel antenna 133 . In the process of personnel operation, it can be considered that the goods corresponding to the goods label have been picked.

In step S280, the mobile device 160 displays the "abnormal" operation state, and then returns to step S210.

FIG. 4 is a flowchart illustrating a warehouse storage in a warehouse management method according to an embodiment of the present invention. The embodiment of FIG. 4 is applicable to the warehouse management system 10 of the embodiment of FIG. 1 , so the embodiment of FIG. 4 will be described below with reference to each device of the embodiment of FIG. 1 .

The embodiment of FIG. 4 describes the process of moving the transport device 200 from the current location of the goods (eg, the first storage location outside the warehouse or in the warehouse) to a specific storage space in the warehouse (eg, the second storage location in the warehouse).

Please refer to FIG. 1 and FIG. 4 at the same time. Steps S310 to S330 are respectively similar to steps S210 to S230 in the embodiment of FIG. 3 , and thus will not be repeated here.

In step S340, the server host 110 determines that the current status of the goods is the warehouse-in status according to the goods labels. Specifically, the inbound status indicates that the goods need to be moved to a specific storage space (eg, a second storage location) within the warehouse. In this embodiment, the server host 110 knows that the goods corresponding to the goods labels need to be moved from the first storage position to the second storage position, so it will determine that the current status of the goods is the storage status, that is, the goods need to be moved to Second storage location.

In step S350, the mobile device 160 displays the operation status of "to be stored". In this embodiment, the server host 110, for example, transmits the current status of the goods (for example, the storage status) to the mobile device 160, and the mobile device 160 displays the operation status (for example, pending storage) according to the current status of the goods, so as to Indicates how the goods should be handled. Accordingly, the operator can know from the mobile device 160 that the operation status of the goods currently being transported is "to be put into storage", and operate the conveying equipment 200 to put the goods into storage according to the operation status of "to be put into storage". In some embodiments, the server host 110 may display the second storage location on the mobile device 160 , for example, so that the operator can operate the transport device 200 according to the display of the mobile device 160 to transport the goods to the second storage location.

In step S360, the landmark antenna 131 will read the RFID landmarks 171, 172, and 173. In this embodiment, the operator will operate the transport device 200 to the second storage location, and as long as an RFID landmark enters the reading range of the landmark antenna 131 along the way, the landmark antenna 131 will read the RFID landmark.

In step S370, the cargo tag leaves the cargo antenna 132. In this embodiment, as long as the cargo antenna 132 continues to satisfy the reading condition of the cargo label, it means that the cargo is still on its way to the second storage location. On the other hand, if the cargo antenna 132 does not read the cargo tag under the set reading conditions, it means that the cargo has been unloaded, so step S380 is entered to update the database 120 .

In step S380, after the goods are unloaded, the server host 110 will update the inventory status of the goods in the database 120 according to the RFID landmark recognized by the landmark antenna 131 last, and display the operation status of "warehousing completed" on the mobile device 160 .

For example, when the operator operates the conveying device 200 to transport the goods to the second storage location and then puts down the goods, the goods tags will leave the goods antenna 132 , and the landmark antenna 131 will recognize the last landmark when the goods tags have not left the goods antenna 132 . will be the landmark located on the route closest to the second storage location. Accordingly, the server host 110 can generate a storage record corresponding to the second storage location according to the landmark finally recognized by the landmark antenna 131 (for example, a record that the goods are placed in the second storage location), and generate a storage record according to the label of the goods and the storage record. The inventory status of the goods in the database 120 is updated, for example, according to the goods label, the number of goods added to the second storage location is recorded, and the like.

FIG. 5 is a schematic diagram of a storage space according to an embodiment of the present invention.

Referring to FIG. 5 , in some embodiments, a warehouse area SP in the warehouse is entered from the left, for example, and is divided into storage spaces R1 , R2 , R3 , and R4 sequentially by RFID landmarks M1 , M2 , M3 , and M4 . When the transport device 200 enters from the entrance of the warehouse area SP and the cargo label leaves the cargo antenna 132 , the servo host 110 can judge whether the cargo is placed in the warehouse according to the last landmark recognized by the landmark antenna 131 when the cargo label has not left the cargo antenna 132 Which storage space of the area SP.

For example, when the transport device 200 passes through the landmarks M1, M2, and M3 and the cargo label leaves the cargo antenna 132, the server host 110 will determine that the cargo label has not left the cargo antenna 132, and the landmark antenna 131 finally recognizes the landmark M3, indicating that the cargo is the position placed in the storage space R3. Accordingly, the server host 110 will be able to update the inventory status of the goods in the database 120 , for example, record the addition of goods corresponding to the goods labels in the storage space R3 of the warehouse area SP.

In addition, the server host 110 also displays the operation status of "warehousing completed" on the mobile device 160 to notify the operator, for example.

It is worth mentioning that the process introduced in the embodiment of FIG. 4 is a warehousing process in which the operator operates normally and without errors. However, in some cases, errors may occur. For example, when the server host 110 knows that the goods corresponding to the goods labels should be stored in the first storage position without moving to the second storage position, the goods may still be picked up from the first storage position by mistake. At this time, the servo host 110 will determine that the current state of the goods needs to be put back into the first storage position. In this case, the server host 110 also transmits the current status of the cargo to the mobile device 160 to display the mobile device 160 , so that the operator can operate the conveying device 200 to return the cargo to the first storage position accordingly. In some embodiments, the server host 110 may, for example, display the first storage location on the mobile device 160 . It must be noted that the various situations in which the transport device 200 carries the goods will be reflected in the identification result of the identification antenna, and this article will not list all possible situations one by one. The description of the embodiments of the invention can be modified according to the requirements.

FIG. 6 is a flowchart of picking materials in a warehouse management method according to an embodiment of the present invention. The embodiment in FIG. 6 is applicable to the warehouse management system 10 in the embodiment in FIG. 1 , so the embodiment in FIG. 6 will be described below with reference to each device in the embodiment in FIG. 1 .

In the embodiment of FIG. 6 , the process of taking out the goods from the storage space (for example, the second storage location in the warehouse) by the transport device 200 is described.

Please refer to FIG. 1 and FIG. 6 at the same time. First, in step S410 , a plurality of identification antennas are identified simultaneously, and the identification results are transmitted to the server host 110 . In this embodiment, the landmark antenna 131 , the cargo antenna 132 and the personnel antenna 133 are identified simultaneously, and the identification results are transmitted to the server host 110 .

In step S420, the landmark antenna 131 will first read the RFID landmark. In this embodiment, the landmark antenna 131 will first read the RFID landmark on the way to the storage space where the goods are located (for example, the second storage location in the warehouse) by the transportation device 200 .

In step S430, the cargo antenna 132 recognizes the cargo tag. In this embodiment, after the transport device 200 arrives at the storage space where the goods are located, the operator moves the cargo to the transport device 200, for example, so the cargo antenna 132 will recognize the cargo tag. As described in the previous paragraph, the cargo antenna 132 may read the cargo tag since any cargo tag comes within the reading range of the cargo antenna 132 . Therefore, the cargo antenna 132 reading the cargo tag does not mean that the cargo corresponding to the cargo tag has been moved to the transport device 200 .

In step S440, the server host 110 determines whether the reading condition of the cargo label is satisfied. In this step, the manner in which the server host 110 determines whether the reading condition of the cargo label is satisfied is similar to steps S230 and S330 in the embodiments of FIG. 3 and FIG. If the condition for reading the cargo label has been satisfied, indicating that the cargo corresponding to the cargo label has indeed been moved to the conveying device 200, the flow will go to step S450. On the contrary, if the reading condition of the cargo label is not satisfied, go back to step S410.

In step S450, the landmark antenna 131 will leave the storage space. In this embodiment, the server host 110 determines that the landmark antenna 131 is separated from the storage space of the goods corresponding to the goods label. In detail, if the server host 110 determines in step S450 that the landmark antenna 131 is removed from the storage space of the goods corresponding to the goods label, it means that the transport device 200 has successfully removed the goods from its storage space.

In step S460, the servo host 110 determines whether the current state of the goods is the picking state. If yes, go to step S470, otherwise go to step S480.

In step S470, the mobile device 160 displays the operation state of "picking material". In this embodiment, when the server host 110 determines in step S460 that the current state of the cargo corresponding to the cargo label is the picking state, it means that the operator's operation is correct, and the cargo has been correctly taken out from its storage space, so it will The operation state of “picking material” is displayed on the mobile device 160 . In some embodiments, the server 110 also updates the inventory status of the goods in the database 120 according to the identification results of the landmark antenna 131 and the goods antenna 132 .

In step S480, the mobile device 160 displays the "abnormal" operation state, and then returns to step S410. In this embodiment, when the server host 110 determines in step S460 that the current state of the cargo corresponding to the cargo label is not the picking state, it means that the operator has made an operation error, and the cargo should not be taken out of its storage space, so the The "abnormal" operation state is displayed on the mobile device 160 .

Taking FIG. 5 as an example, it is assumed that the transport device 200 first passes through the RFID landmarks M1, M2, and M3, then the cargo antenna 132 reads the cargo tag and meets the reading conditions, and then the transport device 200 passes through the RFID landmark M3 again. As a result, it may indicate that the goods corresponding to the goods labels are removed from the storage space R3. If the server host 110 determines that the current status of the goods corresponding to the goods label is the picking status, it will display the operation status of "picking" on the mobile device 160, and update the inventory status in the database 120 to reduce the number of goods in the picking status. The number of storage spaces R3. On the other hand, if the server host 110 determines that the current state of the cargo corresponding to the cargo label is not the picking state, the “abnormal” operation state will be displayed on the mobile device 160, so that the operator can know that the operation is wrong, and will The goods are put back into the storage space R3.

It must be noted that the above several embodiments exemplarily introduce the detailed manner of the actual application of the warehouse management system and the warehouse management method, however, the present invention is not limited to the details of each step in the embodiment, and those with ordinary knowledge in the art When the detailed process of warehouse management can be designed according to its needs.

To sum up, the warehouse management system and the warehouse management method proposed by the embodiments of the present invention can carry out warehouse management more scientifically in an automated manner by setting RFID landmarks in the warehouse and setting up identification antennas on the transportation equipment, reducing the reduction of costs. The false positive rate of cargo handling. On the other hand, the management of RFID landmarks can more accurately record the storage location of goods and improve the convenience of warehouse management.

Although the present invention has been disclosed above by the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the scope of the appended patent application.
