[0072] Specifically, the user can input operation instructions through the key 42, so that the user can timely adjust the information of the cargo loading and unloading device to ensure that the cargo situation in the cargo loading device is consistent with the stored information.

[0073] For example, the user puts goods into the cargo carrying device, and the cargo carrying device is empty. The user directly inputs the operation instruction through the key.

[0074] In the application, a storage module (not shown) may be provided for the cargo carrying device, which stores historical information of the cargo stored in the cargo carrying device, the location of the cargo carrying device (the location of the shelf, the location on the shelf), operation instructions from the shelf, and information on changes in the quantity of the cargo.

[0075] The server of this embodiment is used to receive operation instructions input by users, respond to the operation instructions, determine the corresponding shelf according to the operation instructions, and send the operation instructions to the shelf. The operation instructions include the name of the goods, the preset quantity and the preset operation.

[0076] The preset quantity of the goods is the quantity to be taken out when out of the warehouse or the quantity to be put in when in of the warehouse. The preset operation can be a warehouse in operation or a warehouse out operation.

[0077] In the application, the server determines the goods required by the user from the name of the goods in the operation instruction; determines the number of the shelf bound to the goods based on the corresponding relationship; and sends the operation instruction to the corresponding shelf based on the shelf number.

[0078] In a possible implementation, the operation instruction may further include a product number, and the corresponding server may determine the number of the bound shelf according to the product number.

[0079] In one possible implementation, the server may generate a product locating instruction in response to a user's query instruction, and may send the product locating instruction to a corresponding shelf. The product locating instruction includes an operation instruction, and the operation instruction is transmitted through the product locating instruction to ensure that the shelf performs the locating operation and determines the location of the product.

[0080] In a possible implementation, the server may determine the number of the shelf to which the goods are bound in response to the user's operation instruction, and display the location of the bound shelf and the location of the cargo loading device to the user.

[0081] The shelf of this embodiment is used to receive an operation instruction from a server; determine a corresponding cargo carrying device according to the operation instruction, and send the operation instruction to the cargo carrying device.

[0082] In the application, the main control chip of the gateway module of the shelf is used to receive operation instructions from the server through the first communication unit; after receiving the operation instructions, it controls the LED light to flash and the speaker to make a sound; determines the corresponding cargo device according to the operation instructions; sends the operation instructions to the cargo device through the second communication unit to remind the user of the location of the goods, which can improve the work efficiency of personnel.

[0083] In one possible implementation, the main control chip communicates with the server through the Wi-Fi communication unit, receives operation instructions from the server, and after determining the corresponding cargo device according to the operation instructions, connects with the 433M RF communication module of the cargo device through the 433M RF communication unit, and sends operation instructions to the corresponding cargo device through the communication link.

[0084] The cargo loading device of the present embodiment is used for receiving operation instructions from the shelf through the communication module or receiving operation instructions input by the user through buttons; in response to a preset operation, collecting the current weight of the pallet through the weighing module; based on the single weight of the goods loaded on the pallet, determining the changed quantity of the goods according to the current weight and the last weight of the pallet; if the changed quantity is the same as the preset quantity, executing the first display operation through the display module, the first display operation is to control the indicator light to flash and then go out, and the display module includes an indicator light.

[0085] In the application, after the user finds the designated cargo loading device, when the user puts the goods into the cargo loading device or takes the goods out of the cargo loading device, the weighing module collects the weight of the pallet periodically or whenever the weight of the pallet changes, and determines the changed quantity of the goods based on the weight of each piece of goods loaded on the pallet, the current weight of the pallet and the previous weight. If the changed quantity is the same as the preset quantity, the first display operation is performed through the display module to inform the user that the current outbound or inbound storage has been completed. Among them, the previous weight is the weight collected last time.

[0086] Among them, when the weighing module includes multiple weighing sensors, weighing is performed through the full-bridge principle to collect the weight of the pallet.

[0087] The cargo loading device of this embodiment is also used to send an operation instruction to the shelf through the communication module if the changed quantity is the same as the preset quantity and the operation instruction is an instruction received through a button.

[0088] In the application, when the changed quantity is the same as the preset quantity, it means that the outbound or inbound storage is completed, and the loading device can send the data obtained in the process to the shelf through the communication module.

[0089] The shelf of this embodiment is also used to send the operation instruction to the server after receiving the operation instruction from the cargo loading device.

[0090] In a possible implementation, the operation instruction from the cargo device is received through the 433M radio frequency communication unit. Then the main control chip communicates with the server through the Wi-Fi communication unit and sends the operation instruction to the server to send the final change quantity of the cargo device to the server.

[0091] The server of this embodiment is also used to receive an operation instruction from the shelf and perform an update operation according to the operation instruction.

[0092] In the application, after receiving the operation instruction, the server performs the update operation: the historical quantity of goods is updated according to the operation instruction.

[0093] Specifically, if the preset operation is a warehousing operation, the preset quantity is added to the historical quantity of goods to obtain the latest quantity of goods. If the preset operation is a warehousing operation, the preset quantity is reduced from the historical quantity of goods to obtain the latest quantity of goods.

[0094] It is understandable that the server fails to update the stored information in time when receiving the operation instructions input by the user through buttons, and transmits the operation process record to the gateway of the shelf through the communication transmission unit, and then transmits it to the server, so as to report the operation process record of the current operation to the server to ensure the data consistency between the server and the cargo loading device. The operation process record can assist personnel in picking goods correctly and reduce the situation of wrong picking or accidental picking.

[0095] This embodiment receives operation instructions from the shelf through the communication module or receives operation instructions input by the user through buttons, and the operation instructions include the name of the goods, preset quantity and preset operation; in response to the preset operation, the current weight of the pallet is collected through the weighing module; based on the single weight of the goods loaded on the pallet, the changed quantity of the goods is determined according to the current weight and the previous weight of the pallet; if the changed quantity is the same as the preset quantity, the first display operation is performed through the display module, and the first display operation is to control the indicator light to flash and then go out, and the display module includes an indicator light; if the changed quantity is the same as the preset quantity, and the operation instruction is an instruction received through the button, the operation instruction is sent to the shelf through the communication module, so that the shelf forwards the operation instruction to the server, and the server performs an update operation according to the operation instruction, so as to realize intelligent detection and reporting of the changed quantity of goods in the cargo loading device, assist personnel in picking goods correctly, and reduce the situation of wrong picking and mistaken picking.

[0096] In addition, intelligent detection of the quantity of goods changed in the cargo loading device can assist personnel in picking goods correctly, which can reduce the problem of repeated picking.

[0097] In one embodiment, the server is also used to receive inventory instructions input by the user, and in response to the inventory instructions, send inventory instructions to all shelves; for each shelf, receive the carrying quantity of goods from the cargo loading device of the shelf; compare the carrying quantity of goods with the historical quantity of goods, and if the carrying quantity of goods is different from the historical quantity of goods, send a reminder instruction to the shelf.

[0098] The shelf is further used to receive an inventory command from the server, and in response to the inventory command, send the inventory command to the cargo carrying device; after receiving the amount of goods carried by the cargo carrying device from the cargo carrying device, send the amount of goods carried by the cargo carrying device to the server;

[0099] It is also used to receive a reminder instruction from a server, and in response to the reminder instruction, control the LED light to flash and control the speaker to make a sound.

[0100] The cargo loading device is also used to receive inventory instructions from the shelf through the communication module; in response to the inventory instructions, collect the current weight of the pallet through the weighing module; based on the single weight of the goods loaded on the pallet, determine the amount of goods carried by the pallet according to the current weight of the pallet; and send the amount of goods carried to the shelf through the communication module.

[0101] This embodiment realizes intelligent inventory of the amount of goods carried by each cargo device in each shelf through the inventory information interaction between the server, the shelf and the cargo device, timely discovers abnormal goods situation, and promptly reminds the user to intervene and handle.
