[0047] 4. Analog input: can receive the analog signal of a weighing scale, perform AD conversion, and include algorithms related to the weighing scale

[0048] 5. Data input / output: perform data interaction through a wired network or Bluetooth.

[0049] The intelligent terminal of the hardware management system is responsible for functions such as system information output and human-computer interaction; related functions can also be customized diversely to turn ordinary storage locations into intelligent storage locations.

[0050] In the present invention, the intelligent terminal electronic tag 100 is a microcomputer with a CPU and various internal application programs, equipped with technologies such as screen display, multi-functional lamps, data transmission, buttons, etc., providing an application basis for various operations (order picking, shelving), responsible for functions such as system information output and human-computer interaction, and the related functions are customized diversely.

[0052] In some embodiments, the warehouse management system further includes: a handheld device and a card reader disposed on the handheld device, wherein the card reader is used to read the information displayed on the display screen 30 and send it to the control center.

[0053] In some embodiments, the warehouse management system also includes: a traveling robot on which a card reader is installed.

[0054] It should be noted that for the picking operation site where the shelves have a certain depth of goods, the focus is on solving the inventory difficulties caused by irregular replenishment and shelving, or different products with neat outer packaging but different sizes, or the difference between the account and the actual number caused by the violation of the standard storage number of the cargo position, which affects the accuracy of the inventory quantity and inventory cost. The purpose is to ensure accuracy while reducing the operation cost, review cost, error correction cost of inventory counting and reduce labor expenses.

[0055] In the warehouse management process, after the scattered products are unpacked, their volume becomes even smaller. Whether in the inventory process or the picking process, the problem of inaccurate quantity is prone to occur repeatedly. As a result, the accuracy rate of one inventory is low, which in turn leads to multiple subsequent re-inventories, high inventory operation costs, increased review workload, and longer inventory time. In actual inventory, manual operations often lead to more mistakes, and the inventory results cannot be confirmed for a long time. Especially for third-party storage centers, which are responsible for the inventory amount, the increase in the unit value of goods means that the risk is further increased. This is especially true for commodities that require strict management in the classification.

[0056] Inaccuracies during delivery will exacerbate this problem. In the delivery picking process, due to the small size of the goods, the picking action cannot be standardized, and it is common to grab more or less. It is necessary to manually calculate how many more or less there are, requiring personnel to always concentrate during picking, and also forming certain requirements for personnel's familiarity with the goods. Not only that, but also behind the picking, it is necessary to set up a review position to review the items in the turnover boxes of scattered goods one by one. In addition to the increase in labor costs, the review position will also reduce the delivery speed by more than 30%. The busier the job, the more prominent it is, and the larger the quantity, the more obvious it is. The planning and re-picking of the reviewed wrongly picked goods also take up a certain amount of time and workload.

[0057] The R & D purpose of this product is to solve problems at the current location for both inventory counting and picking. Picking is equivalent to inventory counting, and replenishment is also equivalent to inventory counting, so real-time inventory counting is carried out. For the on-site operation of picking small items in bulk from shelves with high-frequency disassembly and picking, it focuses on solving the problems of low picking efficiency caused by difficult counting during the picking of products with small volume but consistent quality specifications in the process of unpacking in whole packages, and the difficulty of manual inventory counting of goods in the disassembled storage locations, which affects the accuracy of inventory quantity and inventory cost. In addition, while ensuring accuracy, it improves the speed of bulk inventory counting, reduces the operation cost of inventory counting, and reduces labor expenditure.

[0058] In a specific embodiment of the present utility model, in a certain convenience store, the time and cost of bulk inventory counting are reduced from the original inventory counting operation cost of 8 people for 30 hours at 5,280 yuan to being completely completed by one robot in one hour. In a certain warehouse, the inventory accuracy of the bulk area is increased from 92% to 99.5%. The problem discovery is advanced from the end-of-month inventory counting to after each movement, greatly reducing the error accumulation effect.

[0059] At the same time, in the distribution warehouse of a certain convenience store, the original electronic tags only had a single function of indicating the picking quantity, and the operation guidance was not clear (the electronic tube flashed), so the staff was very likely to make mistakes in the picking position and quantity, resulting in a picking operation accuracy rate of 80% and low picking operation efficiency.

[0060] After introducing the intelligent terminal electronic tags, by equipping multiple distributed low-cost microcomputer terminals, a smart control network in the warehouse is formed to achieve a cost-effective intelligent transformation. While ensuring accuracy, it improves the accuracy and speed of various operations, reduces the operation cost, verification cost, and error correction cost, and reduces labor expenditure.
