Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] See Figures 1 to 7 The shelving unit shown includes a storage unit 8, a main controller 5, multiple storage modules, and a display module 9, wherein:

[0033] The storage module is installed inside the container 8, and the display module 9 is installed on the container 8. Multiple partitions 15 are installed inside the container 8. The multiple partitions 15 are distributed sequentially along the height direction of the container 8. The storage module is installed on the partition 15, and the storage module corresponds to the partition 15 one by one.

[0034] The storage module includes multiple storage units and a data acquisition controller 1. Each storage unit includes a storage box 6, a weighing sensor 2, and an indicator light 3. The weighing sensor 2 is located under the storage box 6. For the same storage module, the weighing sensor 2 of one storage unit is connected to the input terminal of the data acquisition controller 1 of that storage module, and the indicator light 3 of that storage unit is connected to the output terminal of the data acquisition controller 1 of that storage module. The main controller 5 is connected to the data acquisition controllers 1 of multiple storage modules and the display module 9. That is, one storage module corresponds to one data acquisition controller 1. One data acquisition controller 1 simultaneously acquires data from multiple weighing sensors 2 on the corresponding storage module and controls the corresponding indicator light 3, reducing communication nodes, reducing the failure rate on the internal communication bus, and ensuring good data real-time performance.

[0035] In this example, the data acquisition controller 1 has multiple input ports and multiple output ports. For a storage module, the number of input ports of the data acquisition controller 1 is the same as the number of weighing sensors 2 of the storage module. The input ports correspond one-to-one with the weighing sensors 2, and the weighing sensors 2 are connected to the input ports via cables. The number of output ports is the same as the number of indicator lights 3 of the storage module. The output ports correspond one-to-one with the indicator lights 3, and the indicator lights 3 are connected to the output ports via cables.

[0036] In some embodiments, the display module 9 includes a display screen, preferably a touch screen, i.e., a human-machine interface (HMI) screen. The display screen shows data from multiple weighing sensors 2, parameters of the items in the storage box 6 (item name, item quantity), and the status of indicator lights 3 (lights on or off). Workers use the HMI screen to perform inbound and outbound operations on the materials inside the storage container 8. When storing or retrieving items, the main controller 5 activates the corresponding indicator light 3 for the appropriate storage unit via the display screen, facilitating operation.

[0037] In this example, to facilitate the operator's use of the display screen to place and retrieve items, the screen is equipped with "store" and "retrieve" buttons. The operator can perform these operations on the display screen. The display screen has a first display state and a second display state. When it is in the first display state, it corresponds to an item being stored; when it is in the second display state, it corresponds to an item not being stored.

[0038] In this example, the data acquisition controller 1 includes a CPU main control chip.

[0039] In this example, the data acquisition controller 1 connects to the main controller 5 via bus 4. Bus 4 includes, but is not limited to, CAN bus, 485 bus, SPI bus, USB bus, and I2C bus. Data acquisition controller 1 uploads the data it acquires to the main controller 5 via bus 4, and can also receive various commands from the main controller 5. Data acquisition controller 1 can simultaneously acquire data from multiple weighing sensors 2 corresponding to the storage module, display parameters of items on multiple storage units, and the status of indicator lights 3, and upload this data to the main controller 5.

[0040] In some implementations, the storage module also includes a display 7, which is connected to the acquisition controller 1. The display 7 can display the parameters of the items in each storage box 6 (the quantity of items, the name of the items, etc.) and the status of the indicator lights 3, so that the operator can intuitively see the status of the items corresponding to the storage module.

[0041] In a preferred embodiment, the front of the container 8 is provided with a protective door that can be opened and closed, and the display module 9 is located outside the container 8. The display module 9 is located on the left or right side of the container 8, and the display module 9 does not need to be located on the front of the container 8, thus saving space inside the container 8.

[0042] SeeFigure 3 The display module 9 is parallel to the front plane of the container 8. The display module 9 is connected to the container 8 through a connecting component. The connecting component includes a first connecting plate 10 and a second connecting plate 11. The first connecting plate 10 and the second connecting plate 11 are connected and perpendicular. One of the first connecting plate 10 and the second connecting plate 11 is connected to the container 8, and the other is connected to the display module 9. The connecting component is set to achieve a fixed connection between the display module 9 and the container 8.

[0043] The display module 9 is also connected to the container 8 via a rotating connector. The rotating connector includes a first plate 12 and a second plate 13, and a connecting shaft 14. The first plate 12 is connected to the container 8, and the second plate 13 is connected to the display module 9. The second plate 13 is rotatably connected to the first plate 12. The rotation of the second plate 13 causes the first plate 12 to rotate, giving the display module 9 a first position and a second position. When the display module 9 is in the first position, it is parallel to the front and rear sides of the container 8. When the display module 9 is in the second position, it is parallel to the left and right sides of the container 8. Specifically, the upper end of the second plate 13 is rotatably connected to the upper end of the first plate 12 via an upper connecting shaft 14, and the lower end of the second plate 13 is rotatably connected to the lower end of the first plate 12 via another upper connecting shaft 14. The rotating connector allows for more flexible adjustment of the display module 9.

[0044] In some embodiments, the connecting component is connected to the container 8 via a longitudinal connector 16, and the rotating connector is connected to the container 8 via the longitudinal connector 16. The longitudinal connector 16 extends along the height direction of the container 8 and has an opening with a certain length. The opening extends vertically and the position of the longitudinal connector 16 is adjustable. After the position of the longitudinal connector 16 is determined, fasteners are installed in the opening to connect the longitudinal connector 16 to the container 8, so that the position of the display module 9 can be flexibly adjusted.

[0045] In some embodiments, the storage box 6 has a storage space for holding items, which is an open space on one side and closed on the other. The lower part of the container 8 is provided with multiple casters to facilitate moving the container 8 to the desired position and to facilitate operation.

[0046] In this example, the data acquisition controller 1 can control the display of the corresponding indicator light 3, including but not limited to red, green or off.

[0047] In one embodiment, the shelving unit includes eight storage modules, each storage module including eight storage units, the eight storage units being distributed vertically along the height of the container 8.

[0048] In some implementations, see Figures 8-9The device also includes a directional antenna array 17, a radio frequency identification (RFID) controller 18, and an RFID tag 19. The directional antenna array 17 is installed in the storage area, which is the area where the container 8 is placed. The directional antenna array 17 is installed underground. The RFID tag 19 is installed at the bottom of the container 8. The RFID controller 18 is connected to both the underground directional antenna array 17 and the RFID tag 19. The monitoring area of ​​the underground directional antenna array 17 is 120°, which can achieve the following effects: on-site determination when the RFID tag 19 enters the effective identification area; off-site detection when the RFID tag 19 moves out of the identification area; spatial isolation identification of RFID tags of two adjacent containers 8; and accurate detection of the container 8 when it enters the storage area.

[0049] The RFID controller 18 includes a reader 181 and an adaptive filter 182. The reader 181 is configured with a multi-channel polling mechanism (scanning period ≤ 200ms).

[0050] In some embodiments, the device further includes a protective plate 20, which is provided on the left and / or right side of the RFID tag 19 to protect the RFID tag 19 from damage. When both the left and right sides of the RFID tag 19 are provided with protective plates 20, the two protective plates 20 extend downward at an angle toward each other.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
