[0090] The specific picking steps of the online picking system in this solution are as follows:

[0091] 1. The warehouse management system scans the pickup order through the front-end page, and the back-end server 3 sends a control to the 2.4G gateway module 2 to control the corresponding item's tag to light up as a reminder;

[0092] 2. After the pickup personnel arrive at the location of the item to be picked up, the picking wristband 1 will automatically collect the UHF number in the illuminated tag. The picking wristband 1 will then transmit the data to the back-end server 3 through the 2.4G gateway module 2 to inform the server that a certain item with a specific number is being picked up.

[0093] 3. After the 2.4G gateway module 2 sends the UHF number of the tag to the backend server 3, the backend server 3 deducts the quantity of goods in the order and updates the inventory data;

[0094] 4. The 2.4G gateway module 2 controls the picking wristband 1 and provides voice reminders about the number of items to be picked;

[0095] 5. The 2.4G gateway module 2 controls the tag to turn off and modifies the inventory quantity displayed on the tag, thus completing the picking process.

[0096] The picking wristband 1 in this solution is a warehouse picking wristband 1 that can automatically read the product tag information during warehouse picking, transmit it to the backend server 3, announce the picking quantity, and synchronously control the tag lights to turn off as a reminder that picking is completed.

[0097] The ultra-high frequency radio frequency module 11 in this solution is an integrated circuit based on 920MHz~925MHz used in wireless communication, electronic tags and radio frequency identification. It includes ultra-high frequency main control chip U4, filter unit 113, high frequency crystal oscillator unit, voice playback unit 13 and indicator light unit 14. After the warehouse staff puts on the picking wristband 1 and powers it on, it continuously reads the tag information of the goods (i.e. UHF tag). The UHF tag is read and sent to the 2.4G wireless module 12 through the serial port.

[0098] The 2.4G wireless module 12 is a wireless communication based on the 2400MHz~2483MHz development frequency band. It uses this frequency to achieve long-distance real-time online communication with the 2.4G gateway module 2. When the 2.4G wireless module 12 receives UHF tag encoded data from the serial port, it will communicate with the 2.4G gateway module 2 through the 2.4G wireless module 12, while waiting for control commands from the 2.4G gateway module 2.

[0099] When a staff member wearing a picking wristband 1 arrives at the goods shelf, the UHF radio frequency module 11 reads the UHF number from the label on the goods on the shelf. After successful reading, it prompts the staff member with an indicator light (i.e., indicator light unit 14) / voice broadcast (i.e., voice broadcast unit 13) with a "beep" sound, and sends the data to the 2.4G wireless module 12 via serial port. The 2.4G wireless module 12, upon receiving the UHF tag encoding data from the serial port, communicates with the 2.4G gateway module 2 to notify the backend server 3 to pick up the goods. Then, the backend server 3 controls the 2.4G gateway module 2 to send the corresponding instruction to the picking wristband 1, which then broadcasts the voice prompt "Please pick up several items".

The picking wristband is equipped with an ultra-high frequency radio frequency module and a 2.4G wireless module. The 2.4G wireless module is electrically connected to both the 2.4G gateway module and the ultra-high frequency radio frequency module. The 2.4G gateway module is electrically connected to an external backend server. The ultra-high frequency radio frequency module on the picking wristband reads the tag information of the illuminated tags on the goods and transmits the read tag information to the 2.4G wireless module. The 2.4G wireless module communicates with the 2.4G gateway module and transmits the received tag information to the backend server through the 2.4G gateway module. The backend server deducts the quantity of goods in the order and updates the inventory data. Simultaneously, the 2.4G gateway module controls the tags on the goods to turn off the lights and modifies the inventory quantity in the tags, completing the picking process. The picking wristband in this solution combines ultra-high frequency and 2.4G technologies to simplify the picking process, thereby improving overall picking efficiency and management level.
