Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of radio frequency, and particularly relates to an archive storage device and a label identification method. BACKGROUND

[0002] In the current information age, with the increasing demand for data storage and the increasing demand for efficiency and accuracy of item management in the industry of archive management and warehouse logistics, the archive cabinet, as a device for efficient use of space and orderly storage of items, has been widely used. The archive cabinet usually has a multi-layer structure, and each layer is divided into several independent storage compartments. This design allows the archive cabinet to accommodate a large number of items in a limited space, meeting the needs of large-scale storage in different scenarios.

[0003] In the practical application of the archive cabinet, in order to realize the information management of the stored items, such as quick and accurate identification, positioning and tracking of items, an antenna is usually provided in each storage compartment. These antennas are connected to the read-write module of the archive cabinet, and the read-write module communicates with the electronic tags (such as radio frequency tags) in the storage compartment through the antennas, thereby obtaining the relevant information of the items.

[0004] However, the existing archive cabinet antenna control system has a significant technical defect. Since the archive cabinet has multiple layers and each layer has several storage compartments, each storage compartment is equipped with an antenna, which results in the read-write module needing to control a large number of antennas in the archive cabinet at the same time. When the read-write module operates multiple antennas at the same time, its load increases sharply. For example, in an archive cabinet system of a certain scale, there may be dozens or even hundreds of antennas that need to be managed and interacted with data by the read-write module at the same time. In order to complete the communication task with these antennas, the read-write module must constantly adjust its working state and process a large amount of data signals, which makes the read-write module long-term overloading.

[0005] Long-term overloading of the read-write module will cause a series of serious problems. First, in order to meet the demand of controlling multiple antennas at the same time, the read-write module needs to output a large power to drive the antennas and ensure the stability of communication. Excessive power output not only increases energy consumption, which does not meet the current trend of energy saving and emission reduction, but more importantly, it will cause great pressure on the electronic components inside the read-write module. The electronic components will generate a large amount of heat under the condition of long-term high-power work, which may cause the performance of the components to decline, accelerate aging, and even cause damage.

[0006] This power is too large and long-term overload state, seriously affected the service life of read-write module. In practical applications, many file cabinets read-write module due to unable to withstand high intensity of work load, in a short time, the need to frequently replace. This not only increases the maintenance cost of equipment, but also may lead to file cabinet system in critical moment can't run normally, affect the efficiency and accuracy of the goods management, bring unnecessary loss to the enterprise or institution.

[0007] Therefore, how to solve the file cabinet read-write module in the control of multiple antennas at the same time appear overload and power problem, improve the service life of read-write module, has become the key technical problems to be solved in the current file cabinet technology field.

[0015] In one embodiment, the antenna array is provided on the same circuit board, and the plurality of antennas of the antenna array are sequentially and spacedly provided on the circuit board along the same axis.

[0016] A label identification method is provided for one of the purposes of the present application, which is implemented based on the archive storage device of the previous purpose, and includes the following steps:

[0017] The master control signal is sent to the control network, so that the plurality of control nodes of the same layer in the control network are controlled by the control nodes of the upper layer to switch work in sequence, and the terminal control node controls the on / off of the antenna electrically connected thereto.

[0018] In one embodiment, in the step of making the plurality of control nodes of the same layer in the control network switch work in sequence under the control of the control nodes of the upper layer, the following specific steps are included:

[0019] The control nodes of the upper layer send cascade control signals to the plurality of control nodes of the next layer electrically connected thereto, so that in the same time slot, one of the control nodes of the next layer works, and the remaining control nodes of the next layer do not work.

[0020] In one embodiment, in the step of sending the master control signal to the control network, so that the plurality of control nodes of the same layer in the control network are controlled by the control nodes of the upper layer to switch work in sequence, and the terminal control node controls the on / off of the antenna electrically connected thereto, the following specific steps are included:

[0030] In the file storage device of the present application, the tag identification module comprises a control network, and the control network has a plurality of control nodes distributed in a tree structure. The control network in the tree structure effectively disperses the load originally concentrated in the read-write module or a single control node. The read-write module and the plurality of control nodes of the control network jointly undertake the control task, and each control node only needs to be responsible for the operation of the antenna within its control range, greatly reducing the burden of a single node.

[0031] Due to the reasonable dispersion of the load, each control node can more efficiently process the data within its responsible range. When identification or read-write operation of the tag in the storage compartment is required, the relevant control node can quickly respond and complete the corresponding task without waiting for the read-write module or the centralized control node to process all tasks before operation. This parallel processing mode greatly shortens the response time of the system and improves the overall operation efficiency of the file storage device.

The multiple control nodes in the same layer of the control network are controlled by the control nodes in the upper layer to sequentially switch work, and the control node at the end controls the on / off of the antenna electrically connected thereto. This orderly control mode ensures that only one antenna is in working state at any time, fundamentally avoiding the mutual interference between multiple antennas. For example, in one shelf layer, multiple storage spaces correspond to multiple antennas, and the control network sequentially opens and closes these antennas according to the predetermined order, so that each antenna is not interfered by other antennas when working, thereby ensuring the quality and stability of signal transmission and improving the accuracy of tag identification.

It should also be understood that terms such as those defined in a general dictionary should be understood to have meanings consistent with those in the context of the prior art, and unless specifically defined as such, should not be interpreted in an idealized or overly formal sense.

[0043] The present application provides an archive storage device, which distributes a control network in a tree structure to disperse the load of read-write modules to each control node of the control network, so as to reduce the load and power of the read-write modules and improve the operation efficiency of the archive storage device.

[0044] In typical embodiments of the present application, in combination with Figure 1 , Figure 3 and Figure 4 , the archive storage device 10 is mainly composed of a rack body 100 and a label recognition module 20. Wherein, the rack body 100 adopts a multi-layer structure design, for the convenience of description, each layer of the rack body 100 is defined as a rack layer 110. The rack body 100 includes a plurality of rack layers 110, which are arranged in close layers along the vertical direction of the archive storage device 10, forming a three-dimensional storage structure. In the present application, it is recommended that the archive storage device 10 be a dense rack or an archive cabinet, but it should not be understood as a limitation of the present application.

[0045] Inside each shelf layer 110, one or more storage compartments 120 are arranged, and multiple storage compartments 120 in the same shelf layer 110 are sequentially arranged along the longitudinal axis of the file storage device 10. These storage compartments 120 serve as the main storage unit of the items and can be used to store various items, including but not limited to files, books, newspapers, and other items that need to be managed.

[0046] In order to effectively identify and manage the stored items, a radio frequency tag is attached to each item. The radio frequency tag stores item information corresponding to the item inside, which includes unique identification information and detailed item information. The tag identification module 20 is equipped with an antenna 400, which can transmit read-write signals to the radio frequency tag. When the radio frequency tag receives the read-write signal, it will return a response signal containing the item information according to the read-write signal. The antenna 400 transmits the response signal to the tag identification module 20 for processing after receiving it. The tag identification module 20 extracts the item information contained in the response signal by analyzing it, thereby accurately obtaining the item information associated with the radio frequency tag.

[0047] The tag identification module 20 specifically includes a read-write module 200, a control network 300, and multiple antenna arrays. Among them, the multiple antenna arrays are arranged in a one-to-one correspondence with the multiple shelf layers 110 of the file storage device 10, that is, each shelf layer 110 is independently arranged with an antenna array. Each antenna array further contains multiple antennas 400, which are respectively arranged in each storage compartment 120 of the corresponding shelf layer 110, ensuring that each storage compartment 120 is equipped with an antenna 400. The antenna 400 is used to transmit read-write signals to the storage compartment 120 to which it belongs, to realize read-write operations on the radio frequency tag attached to the item in the storage compartment 120, and then obtain the item information pre-stored in the radio frequency tag.

[0048] The control network 300 adopts a multi-layer control node architecture, and each layer of control nodes can contain one or more control nodes 310. These multi-layer control nodes are distributed according to a tree structure, in which a control node 310 is arranged at the top of the control network 300, and the control node 310 and the read-write module 200 realize signal interaction through electrical connection. At the bottom of the control network 300, there are several end control nodes 310, which are respectively electrically connected with the antennas 400 in the multiple antenna arrays. Specifically, each end control node 310 is electrically connected with a corresponding antenna 400 to accurately control the working state (on / off) of the antenna 400.

[0049] The read-write module 200 can reasonably distribute part of the load to the control network 300, and use the control network 300 to centrally control the working state of each antenna 400. This load distribution mechanism effectively reduces the load pressure of the read-write module 200 and each control node 310, realizes the balanced distribution of system load, thereby avoiding the performance degradation or failure risk of the read-write module 200 or the control node 310 due to overload. This not only improves the overall working efficiency of the archive storage device 10, but also helps to prolong the service life of the system.

[0050] In the specific implementation of the embodiment, the control node 310 can be in the form of any one of a controller, an electronic switch, a radio frequency switch, or a switch circuit, etc. with a control function, to meet the actual needs in different application scenarios.

[0051] Specifically, the control network 300 distributes the load to each layer of control nodes by configuring multiple layers of control nodes, so as to reduce the load borne by a single control node 310. The specific number of layers of control nodes 310 in the control network 300 can be reasonably set according to actual needs by those skilled in the art after learning the technical solutions of the present application, and the present application does not limit this. However, the specific implementation schemes based on the technical concepts described in the present application all fall within the protection scope of the present application.

[0052] In the typical embodiment of the present application, a four-layer control node architecture is taken as an example for detailed description, but it should be noted that this example is only used to illustrate the technical solutions of the present application and does not constitute any limitation on the protection scope of the present application.

[0053] Specifically, a core control node 310 is configured at the top end of the control network 300, which is referred to as a first-level control node 320 for convenience of description. That is, the first layer of the control network 300 only contains one first-level control node 320, which realizes signal interaction and data transmission with the read-write module 200 through electrical connection.

[0054] The second layer of the control network 300 is configured with multiple control nodes 310, which are referred to as second-level control nodes 330. The multiple second-level control nodes 330 are electrically connected with the first-level control node 320 to receive control instructions from the first-level control node 320. At the same time, the multiple second-level control nodes 330 are set in one-to-one correspondence with the multiple antenna arrays, that is, each second-level control node 330 is responsible for controlling one corresponding antenna array.

[0055] The third layer of the control network 300 is configured with a plurality of control nodes 310, which are referred to as third-level control nodes 340. The plurality of third-level control nodes 340 are divided into groups, and each group of third-level control nodes is electrically connected to the plurality of second-level control nodes 330. Specifically, each second-level control node 330 is electrically connected to a plurality of third-level control nodes 340 in a corresponding group of third-level control nodes 340 to achieve hierarchical control of the third-level control nodes 340. In addition, each group of third-level control nodes is electrically connected to a plurality of antennas 400 in the antenna array corresponding to the corresponding second-level control node 330.

[0056] In this embodiment, in combination with Figure 4 , the antenna 400 adopts a design structure including a loop coil 410. Specifically, the loop coil 410 is provided with a broken gap formed by a physical interval, which is designed to break the continuity of the loop coil 410, thereby forming a non-closed loop. When a radio frequency signal is radiated to the loop coil 410, due to the presence of the broken gap, the loop coil 410 cannot be effectively excited by an external signal to generate a resonant signal, which helps to avoid the mutual coupling phenomenon between the antennas 400, thereby improving the electrical performance and signal transmission stability of the archival storage device 10.

[0057] In the control network 300, the fourth layer at the end of the control network 300 is configured with a plurality of control nodes 310, which are referred to as fourth-level control nodes 350. The plurality of fourth-level control nodes 350 of the fourth layer are arranged in a one-to-one correspondence with the plurality of third-level control nodes 340 of the third layer, i.e., each third-level control node 340 controls one fourth-level control node 350. The fourth-level control node 350 is ingeniously arranged at the broken gap of the loop coil 410 of the antenna 400, and its function is to bridge the two ends of the broken gap, thereby acting as an electronic switch to accurately control the on-off state of the loop coil 410.

[0058] Regarding the specific implementation form of the fourth-level control node 350, any electronic element or circuit with switching function such as a controller, an electronic switch, a radio frequency switch, or a switching circuit is recommended. In this embodiment, for the sake of illustration, the fourth-level control node 350 is taken as an electronic switch as an example for description, but it should be clear that this example does not constitute any limitation on the protection scope of the present application.

[0059] In actual work process, when the third-level control node 340 sends a conduction instruction to the corresponding fourth-level control node 350, the fourth-level control node 350 connects the broken gap of the loop coil 410, so that the loop coil 410 forms a closed loop and is turned on. At this time, the loop coil 410 can emit read-write signals to the outside to realize the communication function with the radio frequency tag.

[0060] On the contrary, when the tertiary control node 340 sends a disconnect instruction to the corresponding quaternary control node 350, the quaternary control node 350 keeps the disconnect gap of the annular coil 410, maintaining the non-closed state of the annular coil 410. In this state, the annular coil 410 cannot emit signals to the outside, and cannot be excited by external signals to generate resonance signals, thereby effectively avoiding the mutual coupling phenomenon between the antennas 400.

[0061] In the typical embodiment of the present application, the read-write module 200 implements work control on the plurality of antennas 400 arranged in the file storage device 10 via the control network 300. Specifically, to effectively avoid the mutual coupling interference problem that can be caused by the simultaneous work of the plurality of antennas 400, the read-write module 200 only controls a single antenna 400 via the control network 300 in the same time slot.

[0062] When the read-write module 200 receives a tag detection instruction, the read-write module 200 outputs a master control signal to the primary control node 320. After receiving the master control signal, the primary control node 320 divides a complete detection period into a plurality of detection time periods according to the number of the secondary control nodes 330, and each detection time period corresponds to a secondary control node 330. The length of the detection time period corresponding to each secondary control node 330 can be set to be the same or different according to actual needs.

[0063] The secondary control nodes 330 are in an electrically connected state with the plurality of tertiary control nodes 340, and the tertiary control nodes 340 are electrically connected with the corresponding antennas 400. In this embodiment, the working time length of the tertiary control node 340 is defined as a time slot for the convenience of description, but it is clear that this does not constitute any limitation on the protection scope of the present application. Since the working time length of the tertiary control node 340 is a time slot, the detection time period length of the secondary control node 330 should be at least the product of the number of the tertiary control nodes 340 electrically connected to the secondary control node 330 and the time length of a time slot. Since the number of the tertiary control nodes 340 electrically connected to each secondary control node 330 can be different, the detection time period lengths of the secondary control nodes 330 can also be the same or different.

[0064] When the secondary control node 330 is controlled to enter the working state, it will control the plurality of tertiary control nodes 340 electrically connected thereto to switch the working state in a predetermined logical order. Specifically, only one tertiary control node 340 is activated to the working state in any time slot, and the remaining tertiary control nodes 340 remain in the non-working state.

[0065] When the third control node 340 is controlled to enter the working state, it will control the fourth control node 350 electrically connected thereto to be turned on, thereby making the annular coil 410 where the fourth control node 350 is located form a closed loop and be turned on. At this time, the annular coil 410 can emit read-write signals to the outside to realize the communication function with the radio frequency tag.

[0066] On the contrary, when the third control node 340 is controlled to be in the non-working state, it will control the fourth control node 350 electrically connected thereto to be kept in the off state, so that the annular coil 410 is in the off state (the annular coil 410 in the off state is referred to as the off coil). If the read-write signals emitted by the annular coil 410 in the working state (the annular coil 410 in the on state is referred to as the on coil) diverge to the off coil, since the off coil is in the off state, it cannot be excited by the read-write signals to generate a resonance signal. Therefore, the mutual coupling phenomenon does not occur between the off coil and the on coil, thereby effectively avoiding mutual interference and improving the electrical performance of the file storage device 10.

[0067] When the second control node 330 is controlled to be in the non-working state, it will control all the third control nodes 340 electrically connected thereto to be in the non-working state. At this time, if the read-write signals emitted by the on coil controlled by other second control nodes 330 in the working state diverge to the off coil corresponding to the second control node 330, since the off coil is in the off state, it cannot be excited by the read-write signals to generate a resonance signal. Therefore, the mutual coupling phenomenon does not occur between the off coil and the on coil, thereby ensuring the stable operation and electrical performance of the file storage device 10.

[0068] Therefore, during the operation of the file storage device 10, the control network 300 ensures that only one annular coil 410 of the antenna 400 is the on coil and the annular coils 410 of the other antennas 400 are the off coils in the same time slot. The read-write signals emitted by the on coil cannot excite the off coil to generate a resonance signal, that is, the mutual coupling phenomenon does not occur between the on coil and the off coil, thereby effectively avoiding the mutual interference between the antennas 400 and significantly improving the electrical performance and signal transmission stability of the file storage device 10.

[0069] Through the reasonable load distribution mechanism of the read-write module 200, the load is evenly distributed to each control node 310 of the control network 300. This not only reduces the load pressure of the read-write module 200 itself, but also avoids the performance bottleneck caused by excessive load of a single control node 310. Therefore, the entire tag identification module 20 realizes load balancing, ensures that the read-write module 200 and each control node 310 operate within the normal power range, avoids the risk of over-power operation, and thereby effectively prolongs the service life of the file storage device 10.

[0070] In this embodiment, combined with Figure 1 Each shelf 110 of the archive storage device 10 has only one storage compartment, and the antenna array is configured to correspond to the storage compartment 120 of each shelf 110 of the archive storage device 10. Specifically, the storage compartments 120 are arranged sequentially along the longitudinal axis of the archive storage device 10, and the multiple antennas 400 in the antenna array are evenly distributed in the storage compartments 120 along the longitudinal axis.

[0071] In traditional file storage methods, file boxes are typically limited to being placed in pre-set fixed locations. This limitation significantly reduces file storage flexibility and space utilization efficiency, making it difficult to meet increasingly diverse file storage needs. The storage compartment 120 of the file storage device 10 of the present invention eliminates the fixed placement limitations of traditional file boxes, significantly increasing storage space.

[0072] Specifically, the storage compartment 120 of the file storage device 10 of the present invention has ample storage space, capable of stably and securely accommodating file boxes with a thickness of at least 2 cm. This fully accounts for the diverse thickness of file boxes used in actual file storage. Whether conventional thicker files or specialized, thicker file boxes, they can all be smoothly accommodated within the storage compartment 120, eliminating the problem of storage failures due to file box thickness issues and significantly expanding the scope of file storage applications.

[0073] Furthermore, the rational internal layout of each storage compartment 120 allows for simultaneous storage of multiple file boxes while ensuring stable placement. This fully utilizes the three-dimensional space of the storage compartment 120, significantly improving storage space utilization compared to traditional fixed-position placement. In practice, users can flexibly place an appropriate number of file boxes within each storage compartment 120 based on the number and type of files, storing more archival materials within a limited space, thereby effectively improving the overall efficiency and economic benefits of archival storage.

[0074] In another embodiment, combined Figure 2 The antenna array is configured to correspond to the multiple storage cells 120 of a shelf 110 of the file storage device 10. Specifically, the storage cells 120 are arranged sequentially along the longitudinal axis of the file storage device 10, and the multiple antennas 400 in the antenna array form a one-to-one correspondence with each storage cell 120 on the shelf 110, that is, each antenna 400 is independently configured to correspond to a storage cell 120.

[0075] In the typical embodiment of the present application, the plurality of antennas 400 of the antenna array are integrated on a circuit board and arranged along the longitudinal axis direction. Based on the above-mentioned working logic of the on-coil and off-coil, each antenna 400 in the antenna array can remain independent during the working process and will not be coupled, thereby effectively avoiding mutual interference between the antennas 400 and ensuring the accuracy and stability of signal transmission.

[0076] The present embodiment recommends that the antenna array is directly printed on the circuit board. This printing method not only simplifies the installation and debugging process of the antenna array, but also improves the electrical connection performance between the antenna array and the circuit board, thereby providing a strong guarantee for the stable operation of the archive storage device 10.

[0077] In one embodiment, the archive storage device 10 further comprises an infrared module, which is in an electrical connection relationship with the read-write module 200. The infrared module is specially configured to detect whether a user is close to the surrounding area of the archive storage device 10.

[0078] When the infrared module detects that a user is close within its detection range, it will generate a corresponding infrared sensing signal. Subsequently, the infrared module transmits the generated infrared signal to the read-write module 200. After receiving the infrared signal from the infrared module, the read-write module 200 will analyze and process the infrared signal, and based on the user proximity information contained in the infrared signal, generate a corresponding tag detection instruction. The tag detection instruction is used to instruct the archive storage device 10 to start the detection process of the stored items.

[0079] According to the obtained tag detection instruction, the read-write module 200 sends a control signal to the control network 300 to trigger the control network 300 to start working. During the working process of the control network 300, it will detect each item stored in the archive storage device 10 one by one according to the preset detection strategy and algorithm. The item information obtained during the detection process, including but not limited to the position, state, and identification of the item, will be fed back to the database by the control network 300 through the data interface. After receiving the item information from the control network 300, the database will perform comparison, analysis, and update operations on the information to ensure that the relevant item information stored in the database is consistent with the actual state of the items stored in the archive storage device 10. Through this process, real-time monitoring and dynamic updating of the item information in the archive storage device 10 are realized, thereby improving the accuracy and efficiency of item management.

[0080] In one embodiment, the hierarchy in the control network 300 can be adjusted to optimize the architecture of the control network 300. Specifically, the third-level control nodes 340 in the third layer in the original architecture of the control network 300 can be deleted, i.e., the control hierarchy is simplified. With this adjustment, the fourth layer control hierarchy in the original control network 300 is redefined as the new third layer, so that the second-level control nodes 330 are directly electrically connected to the fourth-level control nodes 350.

[0081] This architecture optimization method simplifies the transmission path of the control signals by reducing the intermediate control hierarchy, reduces the signal transmission delay, and can reduce the hardware cost and maintenance complexity of the control network 300. At the same time, the direct electrical connection between the second-level control nodes 330 and the fourth-level control nodes 350 helps to improve the transmission efficiency and accuracy of the control instructions, thereby further optimizing the overall performance of the archival storage device 10.

[0082] It should be noted that the architecture optimization method in this embodiment is only one possible implementation scheme and does not constitute a limitation on the protection scope of the present application. In actual applications, the architecture of the control network 300 can be flexibly adjusted and optimized according to specific needs and scenarios.

[0083] The present application also provides a label identification method, which is implemented in combination with Figure 1 or Figure 2 The label identification method is based on the archival storage device 10 described above, and the read-write module 200 of the archival storage device 10 is used to execute the label identification method, so that the read-write module 200 of the archival storage device 10 and each control node 310 are load balanced and do not operate beyond power, and mutual coupling between each antenna 400 can also be avoided, improving the electrical performance of the archival storage device 10. In a typical embodiment of the present application, the label identification method comprises the following specific steps:

[0084] Step S1000, a master control signal is sent to the control network, so that the control nodes in the same layer in the control network are sequentially switched under the control of the control nodes in the upper layer, and the control nodes at the end control the on / off of the antennas electrically connected thereto;

[0085] During the operation of the archival storage device 10, when the read-write module 200 receives a label detection instruction generated by the archival storage device 10 or a label detection instruction output from an external device, the read-write module 200 generates and outputs a master control signal to the first-level control node 320 at the top level in the control network 300.

[0086] The primary control node 320, upon receiving the master signal, will initiate a polling control mechanism for the plurality of secondary control nodes 330 in the second tier of the control network 300. Specifically, the primary control node 320 will activate and control each secondary control node 330 in turn to enter an active state according to a pre-determined timing logic.

[0087] When any secondary control node 330 is controlled by the primary control node 320 to enter an active state, the secondary control node 330 will further control the plurality of tertiary control nodes 340 electrically connected thereto to switch to an active state in turn according to a pre-determined order. Until all tertiary control nodes 340 electrically connected to the secondary control node 330 have completed the turn-by-turn active state, the primary control node 320 will issue a control instruction to stop the currently active secondary control node 330 from working and to control the next secondary control node 330 to enter an active state, thereby achieving a polling working mode for the secondary control nodes 330.

[0088] Similarly, when any tertiary control node 340 is controlled by its superior secondary control node 330 to enter an active state, the tertiary control node 340 will control one or more quaternary control nodes 350 electrically connected thereto to switch to an active state in turn according to a pre-determined order. Until all quaternary control nodes 350 electrically connected to the tertiary control node 340 have completed the turn-by-turn active state, its superior secondary control node 330 will issue a control instruction to stop the currently active tertiary control node 340 from working and to control the next tertiary control node 340 to enter an active state, thereby achieving a polling working mode for the tertiary control nodes 340.

[0089] By analogy, given that the control network 300 is distributed in a tree structure, the control mode adopted by each tier from the quaternary control nodes 350 onwards is consistent with the control mode of the primary control node 320, the secondary control nodes 330, the tertiary control nodes 340 and the quaternary control nodes 350 described above. Based on a full understanding of the foregoing, those skilled in the art can certainly infer the overall control logic of the control network 300 without any doubt. Based on this, to avoid a lengthy patent document, the control logic of the subsequent tiers will not be described here.

[0090] Through the hierarchical polling control mechanism of the control network 300 described above, the control network 300 can ensure that each control node 310 and the equipment electrically connected thereto can work in an orderly and efficient manner during the label detection process, thereby improving the operating efficiency and stability of the entire archival storage device 10.

[0091] In the embodiment, the fourth layer of the control network 300, i.e. the layer in which the fourth-level control nodes 350 are located, is taken as an example to illustrate the end of the control network 300. However, this example is only used to illustrate the technical solutions of the present application and does not constitute any limitation on the protection scope of the present application.

[0092] The fourth-level control nodes 350 and the antennas 400 are electrically connected to each other to realize signal transmission and exchange of control instructions. Specifically, the fourth-level control nodes 350 are responsible for controlling the working states of the antennas 400 electrically connected thereto, i.e. controlling the antennas 400 to be in a working mode or a non-working mode.

[0093] When the third-level control nodes 340 send working instructions to the fourth-level control nodes 350, the fourth-level control nodes 350 control the antennas 400 to enter the working state. At this time, the antennas 400 will emit read-write signals to the outside. If the items placed in the storage compartments 120 are attached with radio frequency tags, the radio frequency tags will emit response signals to the outside after receiving the read-write signals. After receiving the response signals, the antennas 400 will upload the response signals to the read-write module 200 through the control network 300. The read-write module 200 analyzes and processes the response signals to extract the item information corresponding to the items and updates the item information in the database to realize dynamic management and tracking of the item information.

[0094] On the contrary, when the third-level control nodes 340 send stop working instructions to the fourth-level control nodes 350, the fourth-level control nodes 350 control the antennas 400 electrically connected thereto to be turned off, so that the antennas 400 are in the non-working state, aiming to avoid the antennas 400 from interfering with other antennas 400 that are working in the non-working state, thereby ensuring the stability and reliability of the entire control network 300.

[0095] Since each storage compartment 120 is configured with one or more independent antennas 400, each fourth-level control node 350 is electrically connected to a corresponding antenna 400, and each second-level control node 330 is electrically connected to multiple third-level control nodes 340, the time-sharing control of the fourth-level control nodes 350 can be realized through the control network 300. Specifically, each fourth-level control node 350 can be activated in sequence in different time slots, and then the antennas 400 are controlled to work independently in different time slots. This time-sharing control strategy not only effectively avoids the problem of excessive load of the control nodes 310 in the control network 300, but also disperses the load to the read-write module 200 and the control nodes 310 in the control network 300, thereby ensuring the efficient and stable operation of the read-write module 200 and the control network 300.

[0096] On the basis of any embodiment of the tag identification method of the present application, in the step of sequentially switching the operation of the plurality of control nodes of the same layer in the control network under the control of the control node of the previous layer, the following specific steps are included:

[0097] In step S1100, the control node of the previous layer sends a cascade control signal to the plurality of control nodes of the next layer electrically connected thereto, so that in the same time slot, one of the control nodes of the next layer operates, and the remaining control nodes of the next layer do not operate.

[0098] In the control network 300, a hierarchical control structure is adopted, in which the control node 310 in the previous layer and the plurality of control nodes 310 in the next layer are electrically connected to realize signal transmission and control instruction interaction. Specifically, when the control node 310 in the previous layer is in the working state, it will send a cascade control signal to the plurality of control nodes 310 in the next layer electrically connected thereto, respectively. These cascade control signals follow a predetermined timing logic and are used to control the plurality of control nodes 310 in the next layer to switch to the working state in turn and in order.

[0099] The control network 300 ensures that in any same time slot, only one of the plurality of control nodes 310 in the next layer is in the working state, and the remaining control nodes 310 remain in the non-working state. This time-sharing control strategy effectively avoids the signal conflict and interference problem that may be caused by the simultaneous operation of the plurality of control nodes 310, thereby ensuring the stability and reliability of the control network 300.

[0100] When the control signal is transmitted to the terminal control node 310 of the control network 300, the terminal control node 310 will be responsible for controlling the corresponding antenna 400. Since only one terminal control node 310 is in the working state in the same time slot, it is also ensured that only one antenna 400 is in the working state in the same time slot, significantly reducing the mutual interference that may be caused by the simultaneous operation of the plurality of antennas 400, and improving the accuracy and efficiency of the signal transmission of the antenna 400.

[0101] This embodiment disperses the overall load of the control network 300 to each control node 310 through a reasonable load distribution mechanism. Specifically, each control node 310 only undertakes the control task directly related thereto, avoiding the performance degradation or failure risk of a single control node 310 due to excessive load. This load distribution strategy not only improves the robustness of the control network 300, but also helps to prolong the overall service life of the system.

[0102] In this embodiment, the connection relationship between the second-level control node 330 of the second layer and the plurality of third-level control nodes 340 of the third layer in the control network 300 is taken as an example for illustration. The second-level control node 330 is connected to the plurality of third-level control nodes 340 by electrical connection, and sends the cascade control signal to these third-level control nodes 340 respectively. According to the time sequence logic of the cascade control signal, the plurality of third-level control nodes 340 will be switched to the working state in turn and in order, and only one third-level control node 340 is in the working state in the same time slot.

[0103] When a certain third-level control node 340 is in the working state, it will control the fourth-level control node 350 electrically connected thereto to work. After receiving the control signal, the fourth-level control node 350 will turn on the loop coil 410 of the corresponding antenna 400, so that the antenna 400 forms a complete electrical path and transmits the read-write signal externally. Since only one antenna 400 is in the working state in the same time slot, the mutual interference between the plurality of antennas 400 is effectively avoided, and the stability and accuracy of signal transmission are ensured.

[0104] In another embodiment, when the control node 310 located in the upper layer is in the working state, it sends the cascade control signal to the plurality of control nodes 310 located in the lower layer in a broadcast manner. In this embodiment, the contents of the cascade control signal received by the plurality of control nodes 310 in the lower layer are exactly the same.

[0105] The cascade control signal contains the working time or working period information of each of the plurality of control nodes 310 in the next layer. These working time or period are set by the first-level control node 320 to ensure that there is no overlap or intersection between the working time or period of the plurality of control nodes 310 in the next layer. The control node 310 in the upper layer can effectively control the plurality of control nodes 310 in the next layer to switch to the working state in turn, thereby ensuring that only one of the plurality of control nodes 310 in the next layer is in the working state in the same time slot.

[0106] Specifically, the hierarchical relationship in the control network 300 is taken as an example for illustration: the first-level control node 320 in the first layer and the plurality of second-level control nodes 330 in the second layer in the control network 300 realize signal transmission by electrical connection. When the first-level control node 320 is in the working state, it sends the cascade control signal to the plurality of second-level control nodes 330 in a broadcast manner. After receiving the same cascade control signal, these second-level control nodes 330 will work in the predetermined period according to the respective working period information contained in the signal.

[0107] The working periods of the plurality of secondary control nodes 330 contained in the cascade control signal are set to be non-overlapping, thereby effectively avoiding signal conflict and interference problems that can be caused by simultaneous operation of the plurality of secondary control nodes 330, which not only improves the stability and reliability of the control network 300, but also helps to optimize the allocation and utilization efficiency of system resources.

[0108] On the basis of any embodiment of the tag identification method of the application, in combination with Figure 5 In the step of sending a master control signal to the control network to enable the plurality of control nodes of the same layer in the control network to be sequentially switched to work under the control of the control nodes of the previous layer, the step of controlling the on / off of the antenna electrically connected to the terminal control node comprises the following specific steps:

[0109] In step S1200, the master control signal is sent to the primary control node of the control network, and the primary control node sends a primary control signal to the plurality of secondary control nodes to control the plurality of secondary control nodes to be sequentially switched to work, and the plurality of secondary control nodes correspond to the plurality of antenna arrays, respectively.

[0110] When the read-write module 200 receives a tag detection instruction generated by the file storage device 10 itself control system or a tag detection instruction output by an external device, the read-write module 200 will immediately respond to the instruction and output a master control signal to the primary control node 320 at the top level in the control network 300. The master control signal serves as a start signal for the entire detection process and is used to trigger the primary control node 320 to enter a detection period control mode.

[0111] After receiving the master control signal, the primary control node 320 starts a detection period control process. In a complete detection period, the primary control node 320 will control the plurality of secondary control nodes 330 in sequence according to a preset control strategy, so that they enter a working state in a predetermined order. This time-sharing control method ensures that each secondary control node 330 can independently perform its control task in different time periods, avoiding control signal conflict and interference.

[0112] Specifically, for each secondary control node 330, the period in which it is responsible for controlling the plurality of tertiary control nodes 340 electrically connected thereto to work in sequence is defined as a detection period. In the detection period, the secondary control node 330 will accurately control the plurality of tertiary control nodes 340 corresponding thereto to work one by one according to a preset order and timing. Through this control method, it can be ensured that each tertiary control node 340 works at least once in the detection period, thereby realizing comprehensive detection of each layer of the file storage device 10.

[0113] The primary control node 320 acquires the detection period information of each secondary control node 330 in advance before the detection cycle starts. The detection period information includes the specific time points when each secondary control node 330 starts and ends work, and the duration of work and other key parameters. The detection periods of multiple secondary control nodes 330 are added together to form a complete detection cycle. In other words, the primary control node 320 reasonably divides the detection cycle for multiple secondary control nodes 330 to form multiple non-overlapping detection periods, and each secondary control node 330 corresponds to a detection period.

[0114] Moreover, the detection periods of multiple secondary control nodes 330 do not coincide or overlap in time, which ensures that at the same time, the primary control node 320 only controls one secondary control node 330 to be in a working state, while the remaining secondary control nodes 330 are in a non-working state. This time-sharing control method not only improves the resource utilization of the control network 300, but also effectively avoids signal interference and conflict problems that may be caused by multiple control nodes 310 working simultaneously.

[0115] In order to realize the sequential work of the secondary control nodes 330, the primary control node 320 will send cascade control signals to multiple secondary control nodes 330 in accordance with the preset transmission timing. In this embodiment, the cascade control signal sent by the primary control node 320 to the secondary control node 330 is referred to as a primary control signal. When the secondary control node 330 receives the primary control signal, it will immediately respond to the signal and start executing its control task, that is, controlling multiple tertiary control nodes 340 electrically connected thereto to work sequentially.

[0116] The primary control node 320 sends the primary control signal to multiple secondary control nodes 330 in time sequence according to the work timing set by the secondary control nodes 330 in advance. Through timing control, the primary control node 320 can ensure that multiple secondary control nodes 330 switch working states in a predetermined order.

[0117] In addition, each secondary control node 330 corresponds to an antenna array, which is set on one shelf 110 of the file storage device 10. This corresponding setting of the antenna array and the secondary control node 330 enables each antenna array to focus on the detection task of the shelf 110 it is located in, improving the accuracy and efficiency of detection. At the same time, through the centralized control of the secondary control node 330 on the antenna array, flexible adjustment and optimization of the working state of the antenna array can also be realized, further improving the working performance and reliability of the entire file storage device.

[0118] Step S1300, the secondary control node sends secondary control signals to the associated plurality of tertiary control nodes to control the plurality of tertiary control nodes to switch work in sequence, the plurality of tertiary control nodes correspond to the same layer of a plurality of antenna settings respectively, the tertiary control node and the terminal control node corresponding to the antenna are electrically connected;

[0119] When the secondary control node 330 receives the primary control signal sent by the primary control node 320, the secondary control node 330 enters the working state and is ready to perform its preset control task. In this embodiment, the working time of the tertiary control node 340 is taken as an example to describe this embodiment, but it should be clear that this is only an exemplary setting to facilitate the description of this embodiment, and should not be understood as a limitation on the technical solutions of the present application.

[0120] The secondary control node 330 will control the plurality of tertiary control nodes 340 connected thereto in the preset control sequence during the detection period corresponding to the secondary control node 330, so that they are put into the working state according to the predetermined timing. This time-sharing control method ensures that each tertiary control node 340 can independently perform its control task in different time slots, avoiding the conflict and interference of control signals.

[0121] Specifically, the antenna array includes a plurality of antennas 400, the plurality of antennas 400 are respectively arranged in one or more storage compartments 120 of the shelf layer 110, the plurality of tertiary control nodes 340 electrically connected to the same secondary control node 330 are respectively arranged corresponding to the plurality of antennas 400 of the antenna array, the tertiary control node 340 is electrically connected to the antenna 400, and the tertiary control node 340 controls the antenna 400 to work.

[0122] In order to realize the sequential work of the tertiary control node 340, the secondary control node 330 will send cascade control signals to the plurality of tertiary control nodes 340 in the preset sending sequence. In this embodiment, the cascade control signal sent by the secondary control node 330 to the tertiary control node 340 is called the secondary control signal. When the tertiary control node 340 receives the secondary control signal, it will immediately respond to the signal and start to perform its control task, that is, to control the antenna 400 connected thereto to work.

[0123] The secondary control node 330 sends secondary control signals to the plurality of tertiary control nodes 340 in turn according to the working timing preset by the plurality of tertiary control nodes 340. Through such timing control, the secondary control node 330 can ensure that the plurality of tertiary control nodes 340 switch the working state in turn according to the predetermined order. Further, in the same time slot, only one tertiary control node 340 is in the working state, which not only improves the orderliness of the working of the antenna 400, but also effectively avoids the signal interference and conflict problem caused by the simultaneous working of multiple antennas 400.

[0124] In step S1400, the tertiary control node sends a tertiary control signal to the corresponding terminal control node to control the on-off of the terminal control node, so as to control the on-off of the antenna, which comprises a loop coil provided with a broken gap formed by physical spacing, and the terminal control node is bridged to both ends of the broken gap.

[0125] In this embodiment, the terminal control node 310 is a quaternary control node 350. For details of the structure and cooperation relationship between the loop coil 410 of the antenna 400 and the quaternary control node 350, please refer to the cooperation relationship between the loop coil 410 and the quaternary control node 350 described above, which will not be described here again to save space.

[0126] When the tertiary control node 340 is in the working state, it will send a cascade control signal to the quaternary control node 350 electrically connected thereto. For ease of description, in this embodiment, the cascade control signal is referred to as a tertiary control signal. When the quaternary control node 350 receives the tertiary control signal, it will respond to the tertiary control signal and turn on the loop coil 410 of the antenna 400 connected thereto. At this time, the loop coil 410 becomes a conducting coil and has a complete electrical path, so that the antenna 400 can send read-write signals to the outside to realize communication interaction with the radio frequency tag.

[0127] On the contrary, when the tertiary control node 340 does not receive the secondary control signal sent by the secondary control node 330, the tertiary control node 340 will remain in the non-working state. In this case, the tertiary control node 340 will not send a tertiary control signal to the quaternary control node 350. Since the quaternary control node 350 does not receive an effective tertiary control signal, it will not perform the turn-on operation, resulting in that the loop coil 410 is in an open circuit state. Such an open circuit state destroys the integrity of the loop coil 410, making it a broken coil. Since the broken coil lacks a complete electrical path, the read-write signals sent by the conducting coil cannot excite the broken coil to generate a resonance signal, thereby effectively avoiding the mutual coupling phenomenon between the coils. This helps to improve the electrical performance of the file storage device 10 control network 300 and reduce the possibility of signal interference and misoperation.

[0128] In the present embodiment, the tertiary control node 340 has and only has an electrical connection relationship with one quaternary control node 350. This one-to-one connection mode ensures the accuracy and reliability of signal transmission. At the same time, the tertiary control node 340 and the quaternary control node 350 electrically connected thereto work cooperatively in the same time slot, i.e., complete the tasks of signal sending, receiving and processing in the same time period. This cooperative working mode helps to improve the overall working efficiency of the control network 300, reduce signal delay and conflict, and thus optimize the label detection and communication performance of the archival storage device 10.

[0129] Thus, in the archival storage device 10, efficient and stable signal transmission and detection functions are realized through timing control and hierarchical node management. Specifically, in a complete detection cycle, the primary control node 320 activates and controls the plurality of secondary control nodes 330 in turn according to the preset control strategy, ensuring that each secondary control node 330 enters the working state in the intended order. It is worth noting that at any same moment, only one of the plurality of secondary control nodes 330 is in the working state, thereby avoiding conflict and interference of control signals and ensuring the stability of system operation.

[0130] Further, in the detection period corresponding to the secondary control node 330 in the working state, the secondary control node 330 will control the plurality of tertiary control nodes 340 electrically connected thereto in turn according to the preset timing, so that they enter the working state one by one. Similarly, at any same moment, only one of the plurality of tertiary control nodes 340 is in the working state, and this time-sharing control mode effectively improves the utilization rate of control resources and reduces the risk of signal interference.

[0131] When the tertiary control node 340 is in the working state, it will synchronously perform the control operation on the quaternary control node 350 electrically connected thereto and activate the quaternary control node 350 through electrical connection. After receiving the tertiary control signal, the quaternary control node 350 controls the conduction of the annular coil 410 of the corresponding antenna 400, so that the antenna 400 forms a complete electrical path and thus has the ability to transmit read-write signals externally. This process ensures that the antenna 400 can accurately and stably transmit signals in a specific time slot to realize effective communication with the radio frequency label.

[0132] In addition, under the control of the control network 300, only one of the loop coils 410 is in the on state, i.e., forms the on coil, and the rest of the loop coils 410 remain in the off state, i.e., become off coils, in the same time slot. This makes the read-write signal sent by the on coil unable to excite the off coils to generate a resonance signal, thereby effectively avoiding the mutual coupling phenomenon between the coils. By reducing signal interference and false triggering, the electrical performance of the archive storage device 10 is significantly improved, ensuring the accuracy and reliability of tag detection and communication.

[0133] On the basis of any embodiment of the tag identification method of the application, in combination with Figure 6 After the step of controlling the on / off of the antenna electrically connected thereto by the control node at the end, the method further comprises the following specific steps:

[0134] When the antenna is turned on, the antenna is used to emit a read-write signal outwardly.

[0135] When the third control node 310 is controlled to work, the third control node 340 is electrically connected with a corresponding fourth control node 350, and the third control node 340 sends a third control signal to the fourth control node 350. After receiving the third control signal, the fourth control node 350 turns on the loop coil 410 of the antenna 400, so that the loop coil 410 becomes an on coil, and the antenna 400 can emit a read-write signal outwardly.

[0136] Step S3000: receiving, through the antenna, an answer signal returned by a radio frequency tag arranged in a storage compartment in response to the read-write signal;

[0137] Each item placed in each storage compartment 120 has a radio frequency tag attached thereto. When the radio frequency tag receives the read-write signal emitted by the antenna 400, it will respond to the read-write signal and return an answer signal to the antenna 400 that emitted the read-write signal. The answer signal contains item information, which is the unique identification information or related attribute information of the item to which the radio frequency tag is attached.

[0138] After receiving the answer signal, the antenna 400 transmits the answer signal to the read-write module 200 through the control network 300. Since the read-write signal emitted by the antenna 400 has a certain penetration, it may be received and responded to by the radio frequency tag on the item in the adjacent or nearby storage compartment 120 during signal propagation, thereby causing each antenna 400 to receive the answer signal returned by the radio frequency tag in multiple different storage compartments 120 after each time the read-write signal is emitted.

[0139] When the antenna 400 receives multiple response signals, all the received response signals will be uploaded to the read-write module 200 together. However, the read-write module 200 cannot directly distinguish whether each response signal is returned by the radio frequency tag on the item in the storage compartment 120 where the antenna 400 is located or by the radio frequency tag on the item in the adjacent or nearby storage compartment 120 after receiving these response signals.

[0140] To solve this problem, the read-write module 200 needs to classify and remove duplicates of the received multiple response signals. Specifically, the read-write module 200 will classify the response signals according to the item information, signal strength, arrival time, and other characteristic parameters in the response signals, and remove duplicate response signals. Through this processing process, the response signal returned by the radio frequency tag in the storage compartment 120 where the antenna 400 is located can be accurately bound to the antenna 400, thereby completing the de-duplication operation of the response signal and ensuring the accuracy and reliability of subsequent data processing and analysis.

[0141] Step S4000, obtaining signal strength data of multiple response signals received by the antenna, and performing de-duplication processing on the response signals based on the size of the signal strength data, so that the response signal is associated with the storage compartment corresponding to the corresponding antenna;

[0142] When the read-write module 200 receives multiple response signals transmitted by the antenna 400, the read-write module 200 will perform de-duplication processing operation on all received response signals. The core goal of this de-duplication processing is to only keep the response signal returned by the radio frequency tag in the storage compartment 120 where the antenna 400 is located, thereby realizing the accurate binding of the response signal to the storage compartment 120 where the corresponding antenna 400 is located.

[0143] Specifically, during the signal transmission and reception process, when the antenna 400 transmits the read-write signal or the radio frequency tag returns the response signal in response to the read-write signal, the signal strength of the read-write signal and the response signal will gradually weaken as the transmission distance increases. In the same file storage device 10, the distance between the antenna 400 and the radio frequency tag arranged in the same storage compartment 120 is the shortest. Based on this characteristic, when the radio frequency tag returns the response signal, the signal strength data of the signal received by the antenna 400 from the radio frequency tag in the same storage compartment 120 is the largest.

[0144] When the radio frequency tag returns the response signal in response to the read-write signal, the response signal will spread to the storage compartment 120 where the radio frequency tag is located and the adjacent or nearby storage compartments 120. However, since the antenna 400 in the same storage compartment 120 is closest to the radio frequency tag, when the antenna 400 receives the response signal returned by the radio frequency tag, the signal strength data received by the antenna 400 will be significantly greater than the signal strength data received when the radio frequency tag returns the response signal in the adjacent or nearby storage compartments 120. Based on this characteristic, the storage compartment 120 where the corresponding radio frequency tag is pasted can be determined by analyzing the signal strength data of the response signal.

[0145] When processing the response signal, the read-write module 200 will select the response signal with the maximum signal strength data and bind the response signal with the storage compartment 120 where the radio frequency tag returning the response signal is located. At the same time, the read-write module 200 will delete the response signals with smaller signal strength in the same group. In this way, effective deduplication processing of multiple response signals returned by multiple radio frequency tags is realized, ensuring that only the response signals returned by the radio frequency tags in the same storage compartment 120 are retained.

[0146] Based on the above core principle of "only retaining the response signal with the maximum signal strength data returned by multiple radio frequency tags", the read-write module 200 will perform comprehensive and systematic deduplication processing on all received response signals. After this processing procedure, each response signal can be accurately bound with the storage compartment 120 where the radio frequency tag returning the response signal is located, thereby providing accurate and reliable information basis for subsequent data processing, storage compartment 120 positioning, and item management functions.

[0147] Step S5000, obtaining the item information contained in the response signal, and updating the item information to the database;

[0148] After the accurate binding operation of the response signal with the corresponding storage compartment 120 is completed, the read-write module 200 immediately starts to analyze the response signal. By analyzing the response signal, the read-write module 200 can obtain the item information of the item, such as but not limited to the name of the item, detailed specification parameters, warehousing time record, and related information of the person responsible for the warehousing operation. Based on this analysis process, the system realizes effective acquisition of the corresponding item information from the tag signal, and provides a solid data foundation for subsequent item management and query operations.

[0149] After completing the analysis of the item information, the read-write module 200 further performs information binding and database updating operations. Specifically, the read-write module 200 associates and binds the parsed item information with the location information of the corresponding storage compartment 120. The location information of the storage compartment 120 generally includes the number, area, specific layer number, and column number of the storage compartment 120, and other precise spatial positioning data. Through this binding operation, the system establishes a direct mapping relationship between the item information and the physical storage location.

[0150] Subsequently, the read-write module 200 updates the bound item information and storage compartment 120 location information to the database of the system. As the core data storage and management unit of the system, the database is responsible for persistently saving these key information and supporting efficient data query and retrieval operations.

[0151] When a user needs to find a specific item, the system provides a convenient query function. The user can input the item information corresponding to the item (such as the item name, storage time range, etc.) as a query condition, and the system will perform a quick search in the database according to these conditions. Once the matching item information is retrieved, the system will immediately return the location information of the storage compartment 120 associated with the item.

[0152] Based on the obtained location information of the storage compartment 120, the user can quickly locate the corresponding storage compartment 120 and take out the required item from it. This process realizes the quick search and accurate positioning of the item, significantly improving the management efficiency and user experience of the archive storage device 10.

[0153] In summary, the archive storage device of the present application disperses the load to the read-write module and the plurality of control nodes of the control network, avoiding overloading of the read-write module and the single control node, and improving the operating efficiency of the archive storage device; and under the control of the control network, only one loop coil is the conduction coil and the other loop coils are the disconnected coils in the same time slot, so that the read-write signal sent by the conduction coil cannot excite the disconnected coil to generate a resonance signal, thereby avoiding the mutual coupling between the coils and improving the electrical performance of the archive storage device.
