Description

Technical Field

[0001] This utility model relates to the field of materials management technology, and in particular to an automatic materials quantity monitoring system. Background Technology

[0002] In the field of materials management, whether it is a corporate warehouse, a logistics center, or various institutions such as medical and educational institutions, accurate monitoring of the quantity of materials is crucial. The statistics of the quantity of materials directly affect the subsequent material allocation and procurement plans. Currently, the monitoring of the quantity of materials is usually carried out by manual inventory or barcode identification.

[0003] However, manual inventory counting relies on manpower, requiring staff to count and record each item individually. This not only consumes a lot of time and manpower but is also prone to errors such as omissions and misrecordings during manual operation, leading to inaccurate information on the quantity of materials. While barcode recognition improves the efficiency of information entry to some extent, it requires scanning each barcode individually and cannot quickly identify multiple items simultaneously. When materials are entering or leaving the warehouse in batches, the operation is cumbersome and inefficient. Furthermore, barcodes are easily affected by dirt or obstruction, leading to recognition failures and making it impossible to accurately obtain information on the quantity of materials.
