[0070] The picker picks up goods according to the actual lit positions on the shelves in the warehouse, places the barcode or two-dimensional code of a piece of goods under the scanner lens for scanning, and puts the goods into the picking turnover box after verifying that the goods are correct. At this time, the touch display shows the quantity of goods that should be picked and the quantity of goods that have been picked for the current commodity, as well as the name and shape photo of the current goods for the picker to refer to and compare.
[0071] After the picker completes all tasks in this work section, the picker swipes the RFID identity card to end the current task.
[0072] When the full-box picking completes the picking task of this box, the picker can operate the touch display screen of the industrial computer to display the box number of the picking turnover box, the theoretical total weight, the actual total weight, and the weighing verification result, so as to verify the completion status of the task.
[0073] Embodiment 2
[0074] The second usage mode of the present utility model is the binding mode of the intelligent picking truck and the picker's vehicle and person. In this mode, a picker is correspondingly bound to an intelligent picking truck.
[0075] Before the start of each working day, the central computer system assigns the task vehicle numbers of the pickers in each work section. The pickers in each work section swipe the RFID card to pick up the vehicle, and the vehicle corresponds to the person.
[0076] The turnover box barcode of the picking turnover box and the task order number have been bound in the WMS system, and the box number of the picking turnover box and the corresponding shelf number are also stored in the task list of the industrial computer of all intelligent picking trucks in all work sections.
[0077] The picker uses the scanner to scan the barcode or RFID tag on the picking turnover box to confirm that the number of the picking turnover box received by himself is correct. The industrial computer of the intelligent picking truck uploads the power consumption of the picker and the box number of the picking turnover box to WMS.
[0078] The picker arrives at the working position in the warehouse to pick up goods, scans the barcode or QR code of each good with a scanner, and puts it into the picking transfer box after verifying that the product is correct. At this time, the in-vehicle industrial computer displays the quantity of goods to be picked, the quantity of goods already picked, the name and model photo of the current good for the picker to refer to. At the same time, the roof camera takes videos and photos of the goods in the picking transfer box.
[0079] After the picker completes the picking task, the in-vehicle industrial computer displays the box number of the picking transfer box of the goods, the theoretical total weight, the actual total weight, and the weighing verification result.
