[0053] The usage process of this embodiment is as follows:

[0054] When personnel take out materials and tools, they first select item removal on the control panel 8, then swipe the personnel ID card on the card reader 9 to authenticate personal information, and then confirm the information of the taken out items on the control panel 8, and start the QR code reader and weighing device 6 to confirm and save the item information. Finally, the control cabinet 10 controls the blocking device 12 at the corresponding position to descend, and begins to focus on saving image data. After the specified time, the blocking device 12 rises again, and it is considered that the item is taken out.

[0055] When personnel deposit materials and tools, they first select the item to be deposited on the control panel 8, and then swipe the personnel ID card on the card reader 9 for personal identification, and then control the blocking device 12 to descend and start to focus on saving image data. When the delivery box 4 is completely inserted into the storage compartment 21, the trigger device 5 is activated, and the QR code reader and weighing device 6 are activated at the same time, the QR code 11 is identified and the weight of the delivery box 4 is weighed. When the outbound weight stored in the control cabinet 10, the QR code storage information and the weighing result are consistent, the deposited items are deemed to be correct and entered into the control cabinet 10. Finally, the blocking device 12 rises, and the deposit of the items is deemed to be completed.
