Description

Technical Field

[0001] The present application relates to the technical field of warehouse inventory counting, and in particular to a warehouse inventory counting device. Background Art

[0002] Radio frequency identification (RFID) is a contactless automatic identification technology that uses the transmission characteristics of radio frequency signals and spatial coupling (inductive or electromagnetic coupling) or radar reflection to automatically identify objects. Currently, RFID technology is widely used in security checkpoints, warehouse inventory, and unmanned motion sensing.

[0003] Taking warehouse inventory as an example, inventory can be performed using either manual handheld RFID devices or distributed RFID devices. Manual handheld RFID devices use radio frequency technology to read information stored in tags and wirelessly transmit it to the backend for real-time inventory data comparison. Manual handheld RFID devices have a maximum recognition range of 5 meters and rapid tag recognition, making them suitable for manual scanning and inventory counting of items in small, floor-level warehouses. However, due to the maximum recognition range of 5 meters, high-shelf inventory requires the use of a forklift to unload and scan items, making inventory counting more complex. Furthermore, manual inventory counting is inefficient and inconsistent in accuracy.

[0004] Distributed RFID devices, mounted directly on the roof of the warehouse, do not face these issues. They also offer advantages such as continuous reader deployment, controlled interference, a guaranteed 99% recognition rate, separate transmitters and receivers, the ability to avoid the self-interference of handheld RFID devices, and high transmission power for reading tags at long distances. These advantages make them suitable for large, low-shelf automated inventory warehouses. However, distributed RFID devices also present complex installation, low reliability, high costs, potential fire safety risks, and susceptibility to signal interference in narrow gaps, which can prevent some tags from being fully detected in low-shelf areas and densely packed areas, leading to missed tags. Utility Model Content

[0005] The present application provides a warehouse inventory counting device, which solves the problems of complicated inventory counting operation of existing manual handheld RFID devices, low efficiency and unstable precision of manual counting, as well as the problems of complex installation and operation of distributed RFID devices, low reliability, high cost, impact on fire safety, and easy interference of signals in narrow gaps, resulting in the inability to fully detect some labels in the low-level areas and densely placed areas of shelves, and easy occurrence of missed labels.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, embodiments of the present application provide a warehouse inventory counting device. The warehouse inventory counting device includes a signal transmitter, a signal collector, a processor, and a support structure. The signal transmitter is configured to send signals to items to be counted. The signal collector is configured to receive information from the items to be counted based on the signal feedback. The processor is configured to determine inventory data for the items to be counted based on the information received by the signal collector. Furthermore, the signal transmitter, signal collector, and processor are all mounted on the support structure.

[0008] Compared with the prior art, the warehouse inventory equipment of the embodiment of the present application can install the original signal transmitter, signal collector and processor on the support structure to form an assembly. Therefore, when it is necessary to inventory the items to be counted in the warehouse, the items to be counted on all shelves in the warehouse can be inventoryed by moving the entire above-mentioned assembly. Therefore, the problems of complicated inventory operations of manual handheld RFID devices, low efficiency of manual inventory operations, and unstable precision will not occur. In addition, the distributed RFID device does not need to be fixed on the top of the warehouse, so the warehouse inventory equipment of the embodiment of the present application avoids the problems of complex installation operations, low reliability, high cost, impact on fire safety, and susceptibility to interference of signals in narrow gaps caused by installation on the top of the warehouse, resulting in the inability to fully detect some labels in the lower areas and densely placed areas of the shelves, and easy occurrence of missed labels.

[0009] In some embodiments of the present application, the warehouse inventory counting device further includes a moving device configured to support the support structure and drive the movement of the support structure. Therefore, the moving device can move the signal transmitter, signal collector, and processor on the support structure. This allows the signal transmitter, signal collector, and processor on the support structure to move freely within the warehouse, allowing inventory of items to be counted, making inventory operations more convenient.

[0010] The mobile device can be any movable structure. For example, the mobile device can be a chassis with rollers, which can be directly mounted on the supporting structure. The structure of the mobile device is relatively simple.

[0011] For another example, the mobile device is a mobile robot. When inventory is required, the mobile robot can hold up the support structure. When inventory is not required, the support structure can be lowered. The mobile robot can then be charged.

[0012] Moreover, taking a mobile robot as an example, the mobile robot may include a positioning module, such as a GPS positioning module, which can locate the position of the mobile robot in real time. The mobile robot includes a roller assembly and a drive module, and the drive module is transmission-connected to the roller assembly. Furthermore, the drive module is electrically connected to the processor. The processor can also receive a preset path sent by a superior (for example, a remote terminal device), and drive the roller assembly to move along the preset path through the drive module. Thus, the mobile robot can support the above-mentioned assembly parts for automatic inventory along a predetermined route, and the signal transmitter sends a signal to the items to be inventoried, such as sending a signal to the electronic tag of the items to be inventoried. The signal collector receives information based on the signal feedback of the items to be inventoried, and the processor automatically compares and analyzes the report according to the information received by the signal collector, and determines and outputs the inventory data of the items to be inventoried.

[0013] In addition, in order to inventory items at different locations on the shelves, in some embodiments of the present application, the warehouse inventory equipment includes multiple signal transmitters as described above, and the multiple signal transmitters are installed at intervals on the support structure. As a result, multiple signal transmitters can simultaneously send signals to items at different heights and horizontal positions on the shelves, improving the excitation performance and sensitivity. Moreover, in dense labeling scenarios, multiple signals are transmitted concurrently, improving the recognition rate and material label detection rate, and reducing the possibility of missed items. The multiple signal transmitters can be specifically distributed in a matrix.

[0014] Similarly, based on this, in some embodiments of the present application, the above-mentioned warehouse inventory equipment includes a plurality of the above-mentioned signal collectors, and the plurality of signal collectors are installed at intervals on the above-mentioned support structure. The plurality of signal collectors can also cooperate with a plurality of signal transmitters. After the plurality of signal transmitters send signals to a plurality of items to be inventoried at different heights and different horizontal positions on the shelves, each of the plurality of signal collectors is used to receive information fed back by the items to be inventoried based on the signals, thereby improving the receiving performance and sensitivity. Moreover, in a dense labeling scenario, multiple signals are received to improve the reception rate. The above-mentioned plurality of signal collectors can also be specifically distributed in a matrix.

[0015] Moreover, in order to be suitable for shelves of different heights, in some embodiments of the present application, the above-mentioned support structure includes a mounting frame and a rack, and the mounting frame is connected to the rack. The signal transmitter and the signal collector can be fixedly mounted on the mounting frame. The processor is fixedly mounted on the rack. The rack can be connected to the above-mentioned mobile device, or placed directly on the ground. The warehouse inventory equipment also includes a first adjustment mechanism, which is arranged on the above-mentioned rack and is transmission-connected to the mounting frame. The first adjustment mechanism can drive the mounting frame to rise and fall, so that inventory of items can be performed in a variety of typical warehousing scenarios such as 2-meter shelves, 3.5-meter shelves, 4-meter shelves, 7.5-meter shelves, and 10-meter shelves.

[0016] Based on this, the above-mentioned first adjustment mechanism can be implemented in a variety of ways, such as a scissor-type lifting mechanism or a cylinder direct-drive lifting mechanism. In some embodiments of the present application, the above-mentioned first adjustment mechanism includes a fixed pulley, a connecting rope and an adjusting crank. Among them, the fixed pulley is connected to the frame. The connecting rope is wound around the fixed pulley. The adjusting crank is rotatably connected to the frame and is located below the fixed pulley. The mounting frame is movably connected to the frame. One end of the connecting rope is connected to the mounting frame, and the other end of the connecting rope is connected to the adjusting crank. The adjusting crank is used to tighten the connecting rope to drive the mounting frame to move upward; or to loosen the connecting rope to drive the mounting frame to move downward under the action of gravity. Thereby, the signal transmitter and the signal collector on the mounting frame are raised or lowered, and the structure of the first adjustment mechanism is relatively simple.

[0017] Furthermore, to enhance the smoothness of the mounting frame's lifting motion, in some embodiments of the present application, the first adjustment mechanism further includes a guide rod connected to the frame and extending in the vertical direction. The mounting frame is vertically movably connected to the guide rod. Specifically, the mounting frame is vertically movably connected to the frame via the guide rod. Thus, during the lifting process, the mounting frame can move along the guide rod, resulting in smoother lifting motion.

[0018] In order to inventory items at different horizontal locations on the shelves, it is sometimes necessary to adjust the horizontal position of the signal transmitter and signal collector on the mounting frame. Therefore, in some embodiments of the present application, the warehouse inventory counting equipment further includes a second adjustment mechanism, which is transmission-connected to the mounting frame. Furthermore, the second adjustment mechanism is used to drive the mounting frame in a horizontal direction. This allows the horizontal position of the signal transmitter and signal collector on the mounting frame to be adjusted, thereby aligning the signal transmitter and signal collector with the items at different horizontal locations on the shelves.

[0019] The second adjustment mechanism can also adopt a variety of implementation structures. In some embodiments, the warehouse inventory mechanism includes multiple adjustment levers spaced apart. One end of each adjustment lever is rotatably connected to the frame in a horizontal direction, and the other end of the adjustment lever is connected to the first adjustment mechanism. Pushing any adjustment lever causes the guide rod to drive the entire mounting frame horizontally. This allows for free adjustment of the mounting frame's horizontal position, making the adjustment operation relatively simple and also simplifying the second adjustment mechanism.

[0020] Furthermore, for scenarios requiring a wide height adjustment range, in some embodiments of the present application, the two or more adjustment levers are located at the same height of the first adjustment mechanism, forming a single adjustment lever group. The second adjustment mechanism includes two or more adjustment lever groups, each connected to a different height of the first adjustment mechanism. This enhances the connection strength between the second adjustment mechanism and the frame, ensuring smoother horizontal movement of the guide rod, mounting bracket, and the signal transmitter and signal collector mounted thereon.

[0021] In some embodiments of the present application, the warehouse inventory counting device further includes a display device (e.g., a display screen) mounted on the support structure and electrically connected to the processor. The display device can receive and display inventory data sent by the processor. Inventory data can be viewed in real time on the display device, thereby improving convenience.

[0022] Furthermore, in some embodiments of the present application, the above-mentioned warehouse inventory counting equipment further includes an energy storage device (e.g., a battery), which is fixed to the support structure and electrically connected to the signal transmitter, signal collector, and processor. The energy storage device can power the signal transmitter, signal collector, and processor. Thus, during the inventory process, there is no restriction on power wiring, which makes it easier to move the above-mentioned assemblies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0037] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0038] In addition, in this application, directional terms such as "up", "down", "left", "right", "horizontal" and "vertical" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0039] In this application, unless otherwise specified or limited, the term "connection" should be understood broadly. For example, "connection" can refer to mechanical or physical connections. It can be fixed, removable, or integrated; it can be direct or indirectly connected through an intermediary. It can also be understood as physical contact and electrical continuity between components, or as a circuit structure in which different components are connected through physical circuits such as PCB copper foil or wires that can transmit electrical signals.

[0040] With the development of intelligent manufacturing and digital logistics, the automation and unmanned operation of warehousing is a trend. The most fundamental function of warehousing is to ensure the safety of materials. Therefore, there is a huge room for development of effective, flexible, and low-cost inventory solutions. Therefore, this application provides a warehouse inventory counting device that can be used not only for warehouse inventory, but also for security checkpoints and unmanned motion sensing.

[0041] Consider the use of manual handheld RFID devices for inventory counting. Radio frequency technology is used to read the information within tags, which is then wirelessly transmitted to the backend for real-time inventory data comparison. Manual handheld RFID devices have a maximum recognition range of 5 meters and are relatively fast. In long-distance, high-shelf scenarios, a forklift is required to assist with unloading and scanning materials from the warehouse floor. Therefore, manual handheld RFID devices are only suitable for manual scanning and inventory counting of items in small, floor-level storage warehouses. Furthermore, manually reading and identifying tags one by one is inefficient and prone to fatigue, affecting the accuracy of inventory counts.

[0042] Distributed RFID devices, on the other hand, offer advantages such as continuous reader / writer deployment, controllable interference, a guaranteed 99% recognition rate, separate transmitters and receivers, the ability to avoid the self-interference of handheld RFID devices, and the ability to read tags at long distances using high transmission power. These advantages make them suitable for automated inventory counting on large, low-shelf shelves. However, current distributed RFID devices must be fixed to the warehouse ceiling, resulting in a complex and costly installation process, fire safety risks, low reliability, and limited flexibility. Furthermore, during inventory counting, the signals from these distributed RFID devices are susceptible to interference in narrow gaps between shelves, preventing the complete detection of some tags in low-level and densely packed areas of the shelves, leading to issues such as missed tags.

[0043] Therefore, in order to avoid the above problems, the warehouse inventory device of the embodiment of the present application is a distributed RFID device with improved structure. Figure 1The warehouse inventory counting device 1000 of the embodiment of the present application includes a signal transmitter 100, a signal collector 200, a processor 300 and a support structure 400. Among them, the signal transmitter 100 can send a signal to the item to be inventoried 3000, such as sending a signal to the electronic tag on the item to be inventoried 3000. For example, the signal transmitter 100 may include an excitation antenna (also known as a transmitting antenna). The signal collector 200 can receive information based on signal feedback from the item to be inventoried 3000. For example, the signal collector 200 may include a receiving antenna. The processor 300 can determine the inventory data of the item to be inventoried 3000 based on the information received by the signal collector 200. For example, the processor 300 is specifically an industrial computer (such as an edge computing processor). Therefore, the warehouse inventory counting device 1000 of the embodiment of the present application also supports continuous reading and writing, controllable interference, high recognition rate, and separated transmission and reception. It can avoid the self-interference of transmission and reception of manual handheld RFID devices and support high transmission power to read long-distance tags.

[0044] Furthermore, the signal transmitter 100, the signal collector 200 and the processor 300 are all mounted on the support structure 400 to form an assembly. In other words, the embodiment of the present application has an integrated design for the warehouse inventory counting device 1000. Figure 2 As shown, when it is necessary to inventory the items 3000 to be counted in the warehouse, the entire assembly can be moved to inventory the items 3000 to be counted on the shelves 2000 in the warehouse. The signal transmitter 100, signal collector 200, processor 300 and support structure 400 can be pre-assembled, eliminating the need for on-site installation in large-scale storage projects. They are ready for immediate use, eliminating the need for on-site power distribution, wiring, or pipework. There is no need to route wiring to the shelves 2000, nor is there a need to connect power lines in the warehouse. This provides high safety and does not increase the fire risk in the warehouse. Rapid deployment is possible, allowing immediate use, with high reliability and low cost. Furthermore, the layout can be quickly implemented based on the actual area and management needs of the warehouse, and can be flexibly relocated and adjusted as the site adjusts, achieving flexible layout and adjustment. Furthermore, the support structure 400 can be rationally designed in three dimensions based on the actual gaps between the shelves 2000, ensuring that the signal strength remains constant even in narrow gaps. Furthermore, the positions of the signal transmitter 100 and the signal collector 200 on the support structure 400 are designed according to the positions of the items 3000 to be counted on the shelf 2000. This avoids the problem of some tags in the lower and densely packed areas of the shelf 2000 not being fully detected, which can easily lead to the occurrence of missed items.

[0045] The assembly can be used with a forklift in the warehouse by mounting the assembly on the front of the forklift. The forklift can then be used to move the assembly within the warehouse. Alternatively, a dedicated moving device can be incorporated directly into the warehouse inventory counting device 1000 to facilitate the movement of the assembly.

[0046] In some embodiments of the present application, the warehouse inventory counting device 1000 further includes a mobile device 500, which is used to support the support structure 400 and drive the support structure 400 to move. Therefore, the mobile device 500 can move the signal transmitter 100, signal collector 200, and processor 300 on the support structure 400. As a result, the signal transmitter 100, signal collector 200, and processor 300 on the support structure 400 can move freely within the warehouse, allowing inventory of the items to be counted 3000 in the warehouse to be counted, making the inventory operation more convenient.

[0047] Based on the above structure, the mobile device 500 can be a variety of movable structures. For example, the mobile device 500 can be directly mounted on a chassis with rollers, which can be directly mounted on the support structure 400. When the support structure 400 is pushed, the rollers on the chassis rotate, driving the entire warehouse inventory counting device 1000 to move. Thus, inventory counting operations can be performed by manually moving the mobile device 500 through the warehouse aisles. The structure of the mobile device 500 is relatively simple.

[0048] For another example, the mobile device 500 is a cart. The support structure 400 can be fixedly connected to the cart or detachably connected to the cart. Thus, the cart can be manually pushed and moved through the warehouse aisles to perform inventory operations. The structure of the mobile device 500 is also relatively simple.

[0049] For another example, the mobile device 500 is Figure 3 The mobile robot 500a shown is an automated guided vehicle (AGV). During inventory, the mobile robot 500a moves below the support structure and supports the assembly. When inventory is not needed, the support structure 400 is lowered and the mobile robot 500a can be charged.

[0050] The above only describes several different structures of mobile devices 500. The mobile device 500 of the embodiment of the present application can also be other manual or automatic mobile structures, and the present application does not limit this. For a mobile device 500 with an automatic movement function, the mobile device 500 also includes a roller assembly and a drive module, and the drive module is transmission-connected to the roller assembly. In addition, the drive module is electrically connected to the processor 300. For example, the drive module may specifically include a drive motor and a drive circuit board, and the drive motor is transmission-connected to the roller assembly. The drive circuit board is electrically connected to the processor. The processor 300 can also receive a preset path sent by a superior (for example, a remote terminal device) and drive the roller assembly to move along the preset path through the drive module. It should be noted that the mobile device 500 may include a positioning module, such as a GPS positioning module, which can locate the position of the mobile device 500 in real time.

[0051] Thus, the mobile device 500 can support the above-mentioned assembly parts to be automatically counted along a predetermined route. Whenever arriving at any inventory location, the signal transmitter 100 sends a signal to the item to be counted 3000, such as sending a signal to the electronic tag of the item to be counted 3000. The signal collector 200 receives information based on the signal feedback of the item to be counted 3000. The processor 300 can automatically compare and analyze the report (such as with the inventory parameters stored by the processor 300) according to the information received by the signal collector 200, and determine and output the inventory data of the item to be counted 3000. Thereby, the inventory efficiency is improved. For example, the warehouse inventory equipment 1000 of the embodiment of the present application can patrol at a speed of 1.2-1.5 meters per second, and it only takes 4 hours to 8 hours to complete a warehouse of 12,000 square meters (manual labor requires 1-2 weeks), and the inventory efficiency is significantly improved.

[0052] Furthermore, in order to further improve the efficiency of inventory, in some embodiments of the present application, such as Figure 1 As shown, the warehouse inventory counting device 1000 includes multiple signal transmitters 100 as described above, and multiple signal transmitters 100 are installed at intervals on the support structure 400. Multiple signal transmitters 100 can simultaneously send signals to the items to be counted 3000 at different heights and horizontal positions on the shelf 2000, thereby improving the excitation performance and sensitivity. Moreover, in a dense labeling scenario, multiple signals are concurrent, which improves the recognition rate and material label detection rate, and reduces the possibility of missing labels. It should be noted that, if Figure 1 As shown, the multiple signal transmitters 100 are specifically distributed in a matrix.

[0053] Similarly, in some embodiments of this application, continue to refer to Figure 1 , the above-mentioned warehouse inventory equipment 1000 includes a plurality of the above-mentioned signal collectors 200, and the plurality of signal collectors 200 are installed at intervals on the above-mentioned support structure 400. The plurality of signal collectors 200 can also cooperate with the plurality of signal transmitters 100. After the plurality of signal transmitters 100 send signals to the plurality of items to be inventoried 3000 at different heights and different horizontal positions on the shelf 2000, each signal collector 200 in the plurality of signal collectors 200 can receive information based on the signal feedback of the items to be inventoried 3000, thereby improving the receiving performance and sensitivity. Moreover, in a dense tag scenario, multiple signals are received to improve the receiving rate. It should be noted that, if Figure 1 As shown, the multiple signal collectors 200 can also be distributed in a matrix.

[0054] Furthermore, in some embodiments of the present application, the support structure 400 includes a mounting frame 401 and a rack 402, wherein the mounting frame 401 is connected to the rack 402. The signal transmitter 100 and the signal collector 200 can be fixedly mounted on the mounting frame 401. The processor 300 is fixedly mounted on the rack 402. The rack 402 can be connected to the mobile device 500 or placed directly on the ground.

[0055] For example, Figure 1 and Figure 4 As shown, the mounting frame 401 includes a vertical rod 4011, a horizontal rod 4012, and a connecting frame 4013. The middle portion of the horizontal rod 4012 is connected to the middle portion of the vertical rod 4011, that is, the horizontal rod 4012 and the vertical rod 4011 intersect each other at the middle portion. The connecting frame 4013 is connected to the connection between the horizontal rod 4012 and the vertical rod 4011.

[0056] For a warehouse inventory counting device 1000 comprising multiple signal transmitters 100 and multiple signal collectors 200, the multiple signal transmitters 100 can be mounted on the aforementioned mounting frame 401. Furthermore, the multiple signal transmitters 100 can be mounted on the horizontal rods 4012 and vertical rods 4011, respectively. Alternatively, some of the multiple signal transmitters 100 can be mounted on the horizontal rods 4012 and vertical rods 4011, respectively, of the mounting frame 401, while the remaining signal transmitters 100 can be mounted on the aforementioned rack 402.

[0057] Similarly, the plurality of signal collectors 200 may also be mounted on the horizontal rod 4012 and the vertical rod 4011 of the mounting frame 401. Alternatively, some of the plurality of signal collectors 200 may be mounted on the horizontal rod 4012 and the vertical rod 4011 of the mounting frame 401, respectively, while the remaining plurality of signal collectors 200 may be mounted on the rack 402.

[0058] Figure 1 The warehouse inventory counting device 1000 shown in FIG. 1 includes five signal transmitters 100 and three signal collectors 200. Two signal transmitters 100 are located at both ends of the horizontal rod 4012, another two signal transmitters 100 are located at the upper end and the middle of the vertical rod 4011, and the remaining signal transmitter 100 is located at the upper part of the rack 402. Figure 1 and Figure 5 As shown, two signal collectors 200 are respectively located at the middle and lower end of the vertical rod 4011. Among them, one signal collector 200 located at the middle of the vertical rod 4011 is located between the two signal transmitters 100. The remaining signal collector 200 is located at the middle and lower part of the rack 402. The rack 402 can be as follows Figure 3A rectangular parallelepiped frame with a base plate is shown.

[0059] The above describes the specific structure of the support structure 400 and the implementation structure of the mobile function of the support structure 400. In order to be applicable to shelves 2000 of different heights in the warehouse, it is necessary to adjust the height position of the signal transmitter 100 and the height position of the signal collector 200. Therefore, referring to Figure 6 The warehouse inventory counting device 1000 of the embodiment of the present application further includes a first adjustment mechanism 600, which can be disposed on the frame 402 and in transmission connection with the mounting frame 401. For shelves 2000 of different heights, such as 2-meter shelves, 3.5-meter shelves, 4-meter shelves, 7.5-meter shelves, and 10-meter shelves, the first adjustment mechanism 600 can be used to drive the mounting frame 401 up and down to align the signal transmitter 100 and the signal collector 200 with items on shelves 2000 of different heights, thereby achieving an inventory counting function.

[0060] The first adjustment mechanism 600 can be implemented in a variety of ways. For example, a scissor lift mechanism or a cylinder direct drive lift mechanism. In some embodiments of the present application, continue to refer to Figure 6 and Figure 7 The first adjustment mechanism 600 includes a fixed pulley 601, a connecting rope 602, and an adjustment crank 603. The fixed pulley 601 is connected to the frame 402. The connecting rope 602 is wound around the fixed pulley 601. The adjustment crank 603 is rotatably connected to the frame 402 and is located below the fixed pulley 601. The mounting frame 401 is movably connected to the frame 402. One end of the connecting rope 602 is connected to the mounting frame 401, and the other end of the connecting rope 602 is connected to the adjustment crank 603.

[0061] For example, when the adjustment crank 603 is shaken in the first direction P, the connecting rope 602 can be tightened, driving the mounting frame 401 to move upward. The signal transmitter 100 and the signal collector 200 on the mounting frame 401 are correspondingly raised, allowing the inventory of the items 3000 to be counted at a higher position on the shelf 2000. When the adjustment crank 603 is shaken in the second direction Q, the connecting rope 602 can be loosened. The mounting frame 401 can move downward under the action of its own gravity. The signal transmitter 100 and the signal collector 200 on the mounting frame 401 are correspondingly lowered, allowing the inventory of the items 3000 to be counted at a lower position on the shelf 2000. The structure of the above-mentioned first adjustment mechanism 600 is relatively simple.

[0062] Based on the structure of the first adjustment mechanism 600, in order to further improve the running stability of the mounting frame 401, in some embodiments of the present application, the first adjustment mechanism 600 further includes: Figure 7The guide rod 604 shown is connected to the frame 402 and extends in the vertical direction. The mounting frame 401 is movably connected to the guide rod 604 in the vertical direction. Specifically, the mounting frame 401 is movably connected to the frame 402 in the vertical direction via the guide rod 604. Thus, during the lifting process, the mounting frame 401 can move along the guide rod 604, making the movement of the mounting frame 401 smoother.

[0063] Figure 7 and Figure 4 The illustrated first adjustment mechanism 600 includes four guide rods 604 located within the frame 402. The four guide rods 604 extend vertically and are arranged in a square array. The four guide rods 604 are movably connected to the connecting frame 4013 in the mounting frame 401 in the vertical direction. The four guide rods 604 provide stronger and more reliable support for the support frame. Furthermore, the four guide rods 604 can be connected at their upper ends by a connecting rod. The fixed pulley 601 can be mounted on the connecting rod. That is, the fixed pulley 601 is connected to the frame 402 via the connecting rod and the guide rods 604. The fixed pulley 601 can be mounted at the upper ends of the four guide rods 604.

[0064] Similarly, in order to inventory the items 3000 to be counted at different horizontal positions on the shelf 2000, it is sometimes necessary to adjust the horizontal positions of the signal transmitter 100 and the signal collector 200 on the mounting frame 401. Therefore, in some embodiments of the present application, the above-mentioned warehouse inventory device 1000 also includes Figure 7 The second adjustment mechanism 700 is shown in a transmission connection with the mounting frame 401. Furthermore, the second adjustment mechanism 700 can drive the mounting frame 401 to move horizontally. This allows for horizontal adjustment of the signal transmitter 100 and signal collector 200 on the mounting frame 401, allowing the signal transmitter 100 and signal collector 200 to be aligned with items 3000 to be counted at different horizontal locations on the shelf 2000.

[0065] The above-mentioned second adjustment mechanism 700 can also adopt a variety of implementation structures. In some embodiments of the present application, the above-mentioned warehouse inventory mechanism includes a plurality of adjustment pendulum rods 701, and the plurality of adjustment pendulum rods 701 are distributed at intervals. One end of any adjustment pendulum rod 701 is rotatably connected to the frame 402 in the horizontal direction (such as hinged), and the other end of the adjustment pendulum rod 701 is connected to the first adjustment mechanism 600. For example, the plurality of adjustment pendulum rods 701 are distributed at intervals along the circumference of the guide rod 604 in the first adjustment mechanism 600. The other end of the adjustment pendulum rod 701 is connected to the guide rod 604 in the first adjustment mechanism 600. Thus, after pushing any adjustment pendulum rod 701, the guide rod 604 will drive the entire mounting frame 401 to move horizontally. Thus, the horizontal position of the mounting frame 401 can be freely adjusted, the adjustment operation is relatively simple, and the second adjustment mechanism 700 is also relatively simple.

[0066] The warehouse inventory counting device 1000 of the present embodiment can be adjusted horizontally and vertically to accommodate flat storage of items in the warehouse, ensuring optimal detection distance from the electronic tags being detected. For example, it can be controlled to operate within the strongest signal range of the goods tag (e.g., 0-3 meters), enabling real-time and accurate reading with a 99.99% recognition rate (100% recognition rate can be achieved after stable commissioning), meeting the highest requirements in inventory counting scenarios.

[0067] Moreover, for some scenes with a large height adjustment range, in some embodiments of the present application, the two or more adjustment rockers 701 are located at the same height position of the first adjustment mechanism, which can form a Figure 3 The second adjustment mechanism 700 includes two or more adjustment lever groups 701S, each of which is connected to the first adjustment mechanism 600 (e.g., the guide rod 604 in the first adjustment mechanism 600) at different heights. This provides a stronger connection between the second adjustment mechanism 700 and the frame 402, ensuring smoother horizontal movement of the first adjustment mechanism 600 (or the guide rod 604 in the first adjustment mechanism 600), the mounting frame 401, and the signal transmitter 100 and signal collector 200 mounted thereon.

[0068] Based on this, for example, Figure 7 and Figure 3 The second adjustment mechanism 700 shown includes four adjustment rocker groups 701S. Two of the adjustment rocker groups 701S each include four adjustment rocker groups 701, and the four adjustment rocker groups 701 are connected to the same height of the four guide rods 604. These two adjustment rocker groups 701S are connected to different heights of the guide rods 604. The remaining two adjustment rocker groups 701S each include two adjustment rocker groups 701. The two adjustment rocker groups 701 in one adjustment rocker group 701S are connected to two adjacent guide rods 604, while the two adjustment rocker groups 701 in the other adjustment rocker group 701S are connected to the remaining two guide rods 604. The remaining two adjustment rocker groups 701S are also connected to different heights of the guide rods 604.

[0069] In addition to the aforementioned adjustment rocker 701, the second adjustment mechanism 700 may also employ other structures. For example, the second adjustment mechanism 700 may include multiple horizontally extending adjustment rails, to which the aforementioned guide rod 604 may be movably connected. Thus, through the cooperation between the guide rod 604 and the adjustment rails, the horizontal position of the guide rod 604, the mounting frame 401, and the signal transmitter 100 and signal collector 200 mounted on the mounting frame 401 can be adjusted.

[0070] The above describes the height adjustment structure and horizontal position adjustment structure of the mounting frame 401 where the signal transmitter 100 and the signal collector 200 are located. In addition to the above components, the warehouse inventory counting device 1000 of the embodiment of the present application may also include other auxiliary components.

[0071] For example, in some embodiments of the present application, the above-mentioned warehouse inventory counting device 1000 also includes Figure 1 The display device 800 (e.g., a display screen) is shown. The display device 800 is mounted on the support structure 400 and is electrically connected to the processor 300. The display device 800 can receive and display inventory data sent by the processor 300. The inventory data can be viewed in real time on the display device 800, thereby improving convenience.

[0072] Furthermore, in some embodiments of the present application, the above-mentioned warehouse inventory counting device 1000 further includes Figure 3 and Figure 8 Energy storage device 900 (e.g., a battery) is fixed to support structure 400 and electrically connected to signal transmitter 100, signal collector 200, and processor 300. For warehouse inventory counting equipment 1000 with display device 800, energy storage device 900 is also electrically connected to display device 800. Thus, energy storage device 900 can power signal transmitter 100, signal collector 200, processor 300 (and display device 800), thereby eliminating the need for power wiring during the inventory process and facilitating the movement of these assemblies.

[0073] The above-mentioned warehouse inventory counting device 1000 can also be equipped with some protective structures. Thus, it can be applied to material inspection in special environments. For example, the warehouse inventory counting device 1000 of the embodiment of the present application can be applied to harsh environments such as underwater, high temperature, and thick smoke, replacing the existing manual or single-frequency low-speed scanning to collect information. For another example, in unconventional situations such as large-scale events and disaster relief, the flexible layout characteristics of the warehouse inventory counting device 1000 of the embodiment of the present application can also be utilized to achieve rapid implementation and rapid response.

[0074] Also, see Figure 9 , Figure 9 This is one of the schematic diagrams of a method for performing warehouse inventory provided in an embodiment of the present application. Figure 9 As shown, the method can be Figure 1 The method is performed by the warehouse inventory counting device 1000 shown in FIG. The method may include at least steps S901 to S903:

[0075] Step S901: moving within the target area.

[0076] The target area here may include a variety of items to be counted 3000, such as paper towels, toothpaste, clothes, etc.

[0077] For example, in order to achieve "second" level efficiency inventory, the warehouse inventory equipment 1000 can move along a preset path in the target area (for example, the entire warehouse, or a certain area of ​​the warehouse). The preset path here is determined according to the storage type of the target area, which generally includes a first storage type (for example, a ground storage type), a second storage type (for example, a shelf storage type), and other storage types (for example, automated vertical warehouses, shuttle high racks, loft storage, etc.). The ground storage type means that the items to be counted 3000 in the target area are placed directly on the ground; the shelf storage type is the current mainstream storage type, and the target area can generally include shelves of heights such as 2 meters / 3 meters / 3.5 meters / 4 meters / 6 meters / 10 meters.

[0078] It is understandable that the preset path here is set when the warehouse inventory counting device 1000 is put into use. It is mainly based on the placement of the items 3000 to be counted, along the shelves, lanes or corridors, so that the antennas in the warehouse inventory counting device 1000 (including the antennas of the signal collector 200 and the antennas of the signal transmitter 100) are as close as possible to the electronic tags (also known as radio frequency tags) of the items 3000 to be counted, thereby improving the detection rate and saving inventory time. For example, the warehouse inventory counting device 1000 can be controlled to operate within the strongest signal range of the electronic tag, and read accurately in real time to meet the requirements of the most demanding inventory scenarios.

[0079] Among them, if the warehouse inventory counting equipment 1000 does not include the mobile device 500, the entire warehouse inventory counting equipment 1000 can be installed in front of an industrial handling vehicle (i.e., a forklift), and the target object can drive the industrial handling vehicle to shuttle in the target area to achieve efficient inventory.

[0080] Optionally, when the warehouse inventory counting device 1000 includes a mobile device 500, and the mobile device 500 is a chassis with rollers, the target object can apply a force to the warehouse inventory counting device 1000 to control the chassis to move along a preset path. For example, the chassis with rollers is installed in a cart-like structure in the warehouse inventory counting device 1000, and the target object can apply a thrust to the cart-like structure to control the warehouse inventory counting device 1000 to shuttle between warehouse lanes in a target area to perform inventory operations.

[0081] When the warehouse inventory counting device 1000 includes a mobile device 500, and the mobile device 500 is a mobile robot 500a, the mobile robot 500a can automatically cruise along a preset path in the lanes of the target area at a preset speed (e.g., 0.2 m / s). The preset path and preset speed can both be received by the warehouse inventory counting device 1000 from a remote terminal device via the processor 300.

[0082] Step S902: Collect information of the items 3000 to be counted.

[0083] Specifically, the warehouse inventory counting device 1000 can send a signal to the items to be counted 3000 via the signal transmitter 100 and receive information (e.g., the name, model, item ID, etc.) from the items to be counted 3000 based on the signal feedback via the signal collector 200. Sending a signal to the items to be counted 3000 involves sending a signal to the electronic tag attached to the items to be counted 3000. The electronic tag contains a chip and an antenna. The chip stores information about the items to be counted 3000, while the antenna is responsible for receiving and transmitting signals.

[0084] It is understood that the signal transmitter 100 in the warehouse inventory counting device 1000 can send a continuous signal to achieve efficient inventory counting. In other words, the signal is sent to the items to be counted 3000 while moving, that is, the signal is sent while moving.

[0085] Optionally, the signal transmitter 100 in the warehouse inventory counting device 1000 can also send signals intermittently, that is, send signals at multiple fixed locations to reduce the possibility of the same item 3000 to be counted repeatedly feeding back its information, thereby reducing transmission overhead and the complexity of subsequent data analysis. For ease of explanation, in the embodiment of the present application, any inventory position in the preset path may be referred to as the first position, and the next inventory position after the first position may be referred to as the second position. When the warehouse inventory counting device 1000 moves to the first position, the mobile device 500 may be controlled to stop moving, at which point its signal transmitter 100 may send a signal at the first position. If the duration of stay at the first position does not reach the first preset duration (for example, 3 seconds), the warehouse inventory counting device 1000 may wait to receive information fed back by the item 3000 to be counted. If the duration of the stay at the first location reaches a first preset duration (e.g., 3 seconds), the warehouse inventory counting device 1000 can control the mobile device 500 to continue moving along the preset path until the current location of the warehouse inventory counting device 1000 reaches a second location. At this time, the mobile device 500 is controlled to stop moving and continue to send signals at the second location to receive feedback information from the items to be counted 3000 within a second preset duration (e.g., 2 seconds) at the second location. The first preset duration and the second preset duration can be adjusted based on the stacking of the items to be counted 3000 and can be the same or different, and are not limited herein.

[0086] Step S903: Analyze the received information to obtain inventory data corresponding to the items to be counted 3000.

[0087] Specifically, the collector in the warehouse inventory counting device 1000 can automatically transmit the received information back to the processor 300 of the warehouse inventory counting device 1000, and then the processor 300 can perform preprocessing, data comparison and other analysis operations on the received information to obtain the inventory data corresponding to the items 3000 to be inventoried.

[0088] It is understandable that, since labels are introduced in many links during the production and circulation of the items to be counted 3000, in other words, the target area includes not only the electronic tags of the items to be counted 3000, but also the electronic tags of other items (e.g., carriers, material frames, and shelves). These other items may be identified as "information in non-standard fields or information in irregular coding" due to the different compilation standards adopted. In order to avoid the interference of these abnormal information, the above-mentioned preprocessing may include data cleaning (i.e., deleting duplicate information) and abnormal information filtering (i.e., filtering information in non-standard fields and information in irregular coding). In this embodiment of the present application, the information after preprocessing may be referred to as valid information.

[0089] The warehouse inventory counting device 1000 can then compare the valid information with the inventory information (i.e., entries in the system inventory) through the processor 300 to obtain inventory data corresponding to each item to be counted 3000. The inventory data may include the inventory result corresponding to the item to be counted 3000 (e.g., surplus or shortage result), the identification of the item to be counted 3000, the location of the item to be counted 3000 in the target area, etc. A surplus result indicates that the collected quantity of the item to be counted 3000 is greater than the inventory quantity; a shortage result indicates that the collected quantity of the item to be counted 3000 is less than the inventory quantity.

[0090] It is understood that when the mobile device 500 in the warehouse inventory counting device 1000 is a mobile robot 500a, if the inventory result of a certain data to be counted is a shortage result, the warehouse inventory counting device 1000 can also re-inventory the items to be counted 3000. For ease of understanding, please refer to Figure 10 , Figure 10 A method for performing inventory counting in a warehouse provided in an embodiment of the present application is shown in FIG. Figure 2 .like Figure 10 As shown, the method can be Figure 1 The warehouse inventory counting device 1000 shown in FIG. 1 may include a mobile robot 500a, a processor 300, a signal transmitter 100, a signal collector 200, and a display device 800. The method may include at least steps S1001 to S1009:

[0091] Step S1001, start the inventory task.

[0092] Before initiating an inventory task, the target subject (e.g., a user conducting a warehouse inventory) can adjust the support structure 400 of the warehouse inventory device 1000 based on the shelf height of the target area where the items 3000 to be counted are located. For example, the first adjustment mechanism can be used to adjust the height of the antenna (the antenna of the signal transmitter 100 or the antenna of the signal collector 200), and the second adjustment mechanism 700 can be used to adjust the distance between the antenna and the shelf 2000 to better fit the location of the items 3000 to be counted, thereby improving the accuracy of the inventory. The target subject can then power on the warehouse inventory device 1000 to enable it to enter an automated state.

[0093] It is understood that if a start control (e.g., a "Start Inventory" control) is displayed on the interface of the display device 800, the target object can perform a trigger operation on the start control. The trigger operation here can include contact operations such as clicking and long pressing, and can also include non-contact operations such as voice and gestures, which will not be limited here. When the processor 300 in the warehouse inventory counting device 1000 responds to the trigger operation, the inventory task for the target area (i.e., the warehouse where the items to be counted 3000 are located) can be started.

[0094] Optionally, in order to realize the automation and unmanned operation of the warehousing process, the warehouse inventory counting device 1000 can also receive and execute various instructions (start-up instructions, position adjustment instructions, etc.) sent by a remote terminal device. Among them, the terminal devices here may include: smart phones, tablet computers, laptops, desktop computers, smart speakers, smart watches, car terminals, smart TVs and other smart terminals with data processing functions. For example, when the warehouse inventory counting device 1000 receives the start-up instruction sent by the terminal device, it can start the inventory task. In other words, in an embodiment of the present application, the target object does not need to go to the target area and operate on the warehouse inventory counting device 1000, but can operate on a remote terminal device, thereby realizing an unmanned warehouse.

[0095] Step S1002: Based on a preset speed, control the mobile robot to move along a preset path.

[0096] Specifically, the processor 300 in the warehouse inventory equipment 1000 can obtain the preset path and preset speed for the target area in advance. Then, the processor 300 can send the preset path and preset speed to the mobile robot 500a. The mobile robot 500a can move along the preset path at the preset speed, thereby driving the signal transmitter 100, signal collector 200 and other structures to patrol the warehouse area according to the established path.

[0097] Step S1003: Collect information of items to be counted.

[0098] Specifically, while cruising along the preset path in the alleys of the target area, the signal transmitter 100 in the warehouse inventory counting device 1000 can send a signal to the items to be counted 3000, and then the signal collector 200 in the warehouse inventory counting device 1000 can wait to receive information fed back by the electronic tag of the item to be counted 3000 based on the signal.

[0099] Step S1004: pre-processing the received information by the processor to obtain valid information.

[0100] The valid information here refers to the information obtained after data cleaning and filtering of abnormal information. This valid information may include the code content of each item 3000 to be counted. In the warehouse management system (WMS), the code here can be an internal code, such as a license plate number (LPN), which has a fixed storage location, contains materials, and can reflect information such as the weight and volume of its contents.

[0101] Step S1005: Obtain inventory information.

[0102] The inventory information may be stored in a database, which may be deployed on the warehouse inventory counting device 1000 or on other devices having a network connection with the warehouse inventory counting device 1000, which will not be limited here.

[0103] Step S1006: Determine whether the collected quantity of the items to be counted is consistent with the inventory quantity.

[0104] Specifically, the warehouse inventory counting device 1000 can traverse each item 3000 to be counted in the target area through the processor 300, extract the collection quantity of the traversed item 3000 to be counted (for example, paper towels) from the valid information, extract the inventory quantity of the item 3000 to be counted from the inventory information, and then compare the collection quantity with the inventory quantity to obtain the inventory result of the item 3000 to be counted, and determine the inventory data of the item 3000 to be counted based on the inventory result.

[0105] If the collected quantity of item 3000 is consistent with the inventory quantity, the inventory result of item 3000 is determined to be normal. If the collected quantity of item 3000 is inconsistent with the inventory quantity, the inventory result of item 3000 is determined to be abnormal. Specifically, if the collected quantity of item 3000 is greater than the inventory quantity, the inventory result of item 3000 is determined to be a surplus. If the collected quantity of item 3000 is less than the inventory quantity, the inventory result of item 3000 is determined to be a shortage.

[0106] When the traversal is completed, the processor 300 in the warehouse inventory counting device 1000 can generate an inventory analysis table based on the inventory data of each item to be counted 3000. For ease of understanding, please refer to Table 1, which is an inventory analysis table provided in an embodiment of the present application. Among them, the types of items to be counted 3000 in the target area can be 4, for example, specifically including item 1 (for example, conditioner), item 2 (for example, toothpaste), item 3 (for example, paper towels) and item 4 (for example, water). The inventory analysis table generated by the warehouse inventory counting device 1000 can be as shown in Table 1:

[0107] Table 1

[0108] Inventory quantity Collection quantity Item 1 200 190 Item 2 20 20 Item 3 300 300 Item 4 500 500

[0109] It should be noted that the items shown in Table 1 are merely a form of expression for reference. In actual business scenarios, other items (for example, the identification of the items 3000 to be counted, the location of the items 3000 to be counted, etc.) can be established as needed. The embodiment of the present application does not limit the specific form of Table 1.

[0110] It is understandable that if the collected quantity of the items to be counted 3000 is consistent with the inventory quantity, the warehouse inventory counting device 1000 can execute step S1007 to determine that the inventory is completed and display the inventory data on the display device 800.

[0111] If the collected quantity of the items to be counted 3000 is inconsistent with the inventory quantity, the warehouse inventory counting device 1000 may continue to perform the following steps:

[0112] Step S1008: If the inventory data indicates that the collected quantity is less than the inventory quantity, the item to be counted 3000 is re-inventoried.

[0113] Specifically, if the inventory count data indicates that the collected quantity is less than the inventory quantity, the warehouse inventory count device 1000 sends the location of the item to be counted 3000 (e.g., item 1 shown in Table 1) to the target person, so that the target person can confirm whether a new inventory count is required. For example, the item to be counted 3000 is displayed on the display device 800 of the warehouse inventory count device 1000, or the item to be counted 3000 is sent to a remote terminal device to inquire whether a new inventory count is required.

[0114] When the warehouse inventory counting device 1000 receives the confirmation instruction, the warehouse inventory counting device 1000 can determine the item to be counted 3000 as the target item, determine the position of the item to be counted 3000 as the target position, control the mobile robot 500a to move to the target position, and resend the signal through the signal transmitter 100 to wait for receiving feedback information from the target item.

[0115] Step S1009: Determine the difference factors based on the re-inventory information.

[0116] Specifically, the warehouse inventory counting device 1000 pre-processes the information after the re-inventory counting to obtain valid information after the re-inventory counting. The valid information after the re-inventory counting can then be compared with the inventory information again to obtain new inventory counting data. If the new inventory counting data indicates that the inventory counting result is normal, the process jumps to step S1007 to determine that the inventory counting is complete. If the new inventory counting data indicates that the inventory counting result is still a profit or loss result, the difference factor corresponding to the profit or loss result is determined (for example, the target item has been transferred out). At this time, the processor 300 in the warehouse inventory counting device 1000 sends the new inventory counting data to the display device 800 for display.

[0117] It is understandable that, when displaying new inventory data, the display device 800 may also display an adjustment control, where the adjustment control is used to instruct the target object to update inventory information and adjust account differences.

[0118] In an embodiment of the present application, when it is necessary to count the items 3000 to be counted in a target area, rather than collecting information about the items 3000 at a fixed location, the warehouse inventory counting device 1000 can be moved to achieve multi-threaded concurrent, high-powered automatic inspections in densely populated areas, thereby more accurately collecting information about the various items 3000 to be counted in the target area. This can effectively reduce the situation where items are placed too densely and cannot be fully detected. Subsequently, through a wireless connection management system, the data is automatically cleaned and the inventory is automatically compared, thereby improving the detection rate. In addition, when the inventory result of a certain item 3000 to be counted is detected as a shortage result, the warehouse inventory counting device 1000 can also re-inventory it, thereby improving the accuracy of the inventory. The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions that can be easily conceived by any person skilled in the art within the technical scope disclosed in this application should be covered by the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
