Description

Technical Field

[0001] This application relates to the field of electronic device management, and more specifically, to an array-type e-ink screen nameplate workstation. Background Technology

[0002] With the rapid development of green meetings and intelligent office trends, traditional paper or acrylic nameplates are gradually being replaced by electronic display devices due to their cumbersome production, resource waste, and single-use limitations. E-ink screens, with their ultra-low power consumption (bistable display), comfortable paper-like visual experience, and power-off image retention, have become the preferred medium for meeting room identification. The core driving force behind building such systems lies in utilizing digital management to achieve real-time import and batch updates of meeting lists, thereby significantly reducing manual deployment costs and supporting efficient equipment reuse to meet the high-frequency, fast-paced meeting needs of modern business activities.

[0003] However, despite the increasing maturity of e-ink screen technology itself, existing technologies still have significant pain points and gaps in physical operation and cluster management for large-scale conference scenarios. Current solutions do not provide integrated storage and protection methods suitable for such sophisticated electronic devices. During idle storage or transportation, devices are often randomly stacked due to the lack of dedicated carriers, making them highly susceptible to compression, friction, and collisions, leading to irreversible physical damage to the screen and casing. Simultaneously, existing workflows exhibit severe fragmentation and inefficiency. So-called wireless batch updates are limited by wired physical preparation; operators must manually power on or connect a large number of nameplates one by one. This cumbersome pre-processing negates the efficiency advantages of wireless technology. More importantly, existing technologies lack an effective mapping and feedback mechanism between physical devices and digital identities, resulting in a disconnect between physical location and content updates. After the backend software refreshes the screens of hundreds of nameplates, operators cannot quickly identify the location of a specific person's nameplate when faced with a uniform array of hardware. They are forced to resort to the primitive mode of finding devices by visually inspecting each one, which severely slows down the overall setup efficiency of the venue when the number of devices is large.

[0004] Furthermore, existing multi-slot management solutions typically follow a mechanical, linear allocation strategy (i.e., filling in sequentially according to access order). This single-dimensional allocation logic completely ignores the differences in human ease of operation caused by varying heights of the racks in the vertical direction (i.e., the difference between the golden comfort zone and the squatting / stance-intensive zone). It also fails to analyze the semantic weights of personnel importance or group correlation implied in the participant list data. As a result, frequently accessed or high-priority critical equipment is often randomly assigned to the bottom or top edge areas where physical operation is more difficult, while related equipment groups that should be centrally distributed are physically dispersed, making it impossible to achieve intelligent adaptation of physical resources based on ergonomic optimal solutions and maximizing business weights.

[0005] Therefore, an array-type e-ink screen nameplate workstation is desired. Summary of the Invention

[0006] To address the aforementioned technical problems, this application is proposed. Embodiments of this application provide an array-type electronic ink screen nameplate workstation.

[0007] According to one aspect of this application, an array-type e-ink screen nameplate workstation is provided, comprising: a movable base assembly, a vertical cabinet shell, a back cover, a top control console cover, a touch interactive terminal, an array-type support frame, multiple modular storage compartments, e-ink screen nameplates, a central control unit, and a power supply and data bus; The vertical cabinet shell is fixedly connected to the movable base assembly by bolts, and the back cover is fastened to the back opening of the vertical cabinet shell by screws to enclose and form a semi-enclosed internal storage space. Among them, the array-type support frame is vertically housed in the internal space of the vertical cabinet shell. On the array-type support frame, multiple modular storage compartment units are installed in a matrix along the horizontal and vertical directions. The front opening of each modular storage compartment unit is aligned with the opening reserved on the panel of the vertical cabinet shell to form a channel for inserting the e-ink screen nameplate. The top control panel cover is fixedly installed on the top surface of the vertical cabinet shell, and the touch interaction terminal is embedded in the sloping surface of the top control panel cover. The central control unit is located inside the vertical cabinet shell and is electrically connected to the touch-screen terminal and each modular storage compartment unit via power supply and data bus.

[0008] In the aforementioned array-type e-ink screen workstation, the touch interaction terminal is embedded in the sloping surface of the top control panel cover and tilted towards the operator.

[0009] In the aforementioned array-type e-ink screen nameplate workstation, each modular storage unit has a flexible metal contact deep inside, and each modular storage unit has a visual positioning indicator light on its outer panel.

[0010] In the aforementioned array-type e-ink display nameplate workstation, when the e-ink display nameplate is fully inserted into the modular storage compartment unit, the metal pad at the rear of the e-ink display nameplate physically contacts the elastic metal contacts of the modular storage compartment unit, thereby integrating the e-ink display nameplate into the power supply and data bus network.

[0011] In the aforementioned array-type e-ink display nameplate workstation, the central control unit is further configured to: respond to the hardware connection action of the e-ink display nameplate being connected to the modular storage unit; read the unique device identifier of the e-ink display nameplate via the power supply and data bus; and bind and map the unique device identifier to the physical slot coordinates of the modular storage unit to obtain a slot device topology mapping table; based on externally input participant list data, perform node allocation and image rendering calculations on the participant list data using the slot device topology mapping table to obtain the device display update data stream; and distribute the device display update data stream to the corresponding units via the power supply and data bus. The system refreshes the e-ink table card and generates a system ready status flag after confirming that the data writing is complete and the screen display is updated. In response to the retrieval command initiated by the user terminal when the system ready status flag is activated, the system uses the target object information carried by the retrieval command to perform reverse addressing in the slot device topology mapping table to resolve the physical address of the target device and generate a positioning control electrical signal. The positioning control electrical signal is loaded into the driving circuit of the visual positioning indicator corresponding to the physical address, and the light-emitting element is driven to perform a preset flashing action by controlling the current to output a physical guiding light effect indicating the specific storage location of the target device.

[0012] In the aforementioned array-type e-ink screen nameplate workstation, the central control unit is further used to: utilize the physical coordinate data in the slot device topology mapping table and preset ergonomic height parameters to perform spatial efficiency evaluation calculations on each modular storage unit to generate an ergonomic value matrix; based on the preset personnel priority attributes and ergonomic value matrix in the participant list data, perform utility-maximizing adaptive allocation of the participant list data and modular storage units using a greedy strategy to obtain an optimized allocation mapping table that establishes the correspondence between personnel and equipment; and perform differential rendering and data stream protocol encapsulation on the optimized allocation mapping table to obtain the device display update data stream.

[0013] In the aforementioned array-type e-ink screen nameplate workstation, the central control unit is further configured to: perform a space efficiency evaluation calculation for each modular storage unit using the following formula: ;in, This indicates the vertical height level of slot i. The preset optimal height threshold for human body access. The horizontal position coordinates are... The horizontal center coordinates of the rack and These are the high-weight factor and the horizontal-weight factor, respectively.

[0014] Compared to existing technologies, this application provides an array-type e-ink screen nameplate workstation. By constructing an array-type storage matrix with electrical sensing capabilities, it automatically establishes a topological mapping between physical coordinates and device IDs upon device access, thereby incorporating discrete hardware entities into a unified digital management domain and solving the problems of cumbersome charging and lack of protection. Addressing the challenge of physical positioning, the system utilizes reverse addressing logic to drive visual signage next to the slots, translating the software's search intent into real-time light-effect guidance in the physical space. More importantly, an adaptive scheduling strategy based on ergonomic potential energy and business semantic weights is introduced at the data distribution layer. By calculating the comfort gradient of physical slots and the value level of personnel data, it intelligently guides high-priority tasks to the optimal operating area, achieving a closed-loop process and maximizing efficiency from batch data refresh to physical entity delivery.

[0028] To address the technical problems existing in the management of e-ink screen nameplates, such as the lack of physical protection, cumbersome batch energy preparation, difficulty in locating devices after updates, and inefficiency in resource allocation due to neglect of ergonomics, this application constructs an array-type workstation system with deep hardware and software collaboration. Specifically, the solution proposes an array-type e-ink screen nameplate workstation. Firstly, it achieves plug-and-play functionality through modular physical interfaces, automatically closing the power supply link and mapping the "device ID-physical slot" topology upon connection, thus integrating scattered hardware into a unified digital sensing network. Secondly, the system executes an intelligent scheduling algorithm based on ergonomic potential fields and data semantic weights. By quantitatively evaluating the comfort of using physical slots and the value level of attendees, high-priority display tasks are automatically matched to the optimal work height zone, and batch image differential updates are completed through bus technology. Finally, in conjunction with a visual guidance mechanism, the system reverse-engineers the target location during retrieval and drives the corresponding slot's indicator light to illuminate, converting Ethernet domain digital commands into real-time operational lighting effects in the physical space. This ensures device safety and charging while achieving a closed-loop operation from intelligent data arrangement to precise physical retrieval.

[0029] Figure 1 This is a front view of an array-type electronic ink screen nameplate workstation according to an embodiment of this application. Figure 2 This is a side view of an array-type electronic ink screen nameplate workstation according to an embodiment of this application. Figure 3 This is a three-dimensional structural diagram of an array-type e-ink screen nameplate workstation according to an embodiment of this application. Figure 1 , Figure 2 and Figure 3As shown, the array-type e-ink screen nameplate workstation according to an embodiment of this application includes: a movable base assembly 7, a vertical cabinet shell 5, a back sealing cover 4, a top control console cover 6, a touch interactive terminal 1, an array-type support frame 2, multiple modular storage compartment units 3(a), e-ink screen nameplates 3(b), a central control unit, and a power supply and data bus; wherein, the vertical cabinet shell 5 is fixedly connected to the movable base assembly 7 by bolts, and the back sealing cover 4 is fastened to the back opening of the vertical cabinet shell 5 by screws to enclose a semi-enclosed internal accommodating space; wherein, the array-type support frame 2 is vertically housed in the internal space of the vertical cabinet shell 5, and multiple modular storage compartment units 3 are matrix-mounted on the array-type support frame 2 in the horizontal and vertical directions, and the front opening of each modular storage compartment unit 3 is aligned with the opening reserved on the panel of the vertical cabinet shell 5 to form a channel for inserting the e-ink screen nameplates 3(b). The top control panel cover 6 is fixedly installed on the top surface of the vertical cabinet shell 5, and the touch interaction terminal 1 is embedded in the inclined surface of the top control panel cover 6. The central control unit is located in the internal space of the vertical cabinet shell 5 and is electrically connected to the touch interaction terminal 1 and each modular storage compartment unit 3(a) through the power supply and data bus, respectively.

[0030] Specifically, as a high-density integrated management and control device, the array-type e-ink display nameplate workstation has a large physical weight under full load. Furthermore, its integrated precision electrical system has strict requirements for dustproofing, moisture-proofing, and impact resistance. Without stable mechanical support and a closed protective environment, it is highly susceptible to structural deformation or internal circuit damage during frequent movement and transportation. The vertical cabinet shell 5 is bolted to the movable base assembly 7, and the rear sealing cover 4 is screwed to the rear opening of the vertical cabinet shell 5 to form a semi-enclosed internal storage space. This creates a physical base with high mechanical rigidity and environmental isolation capabilities. This effectively ensures the structural stability of the entire device when moved between different venues, while providing necessary physical barriers for the internal array-type load-bearing frame and central control unit, preventing external foreign objects from intruding or device failure caused by transportation vibrations. During the process, the assemblers first place the mounting flange face at the bottom of the vertical cabinet shell 5 flat on the bearing surface of the movable base assembly 7, accurately calibrate the preset mounting hole positions of both, and use high-strength hex bolts with spring washers to insert them one by one and apply the rated torque with a torque wrench to lock them, thereby eliminating the gap between the mating surfaces and establishing a rigid connection body; then, attach the back sealing cover plate 4 to the edge of the rectangular frame on the back of the vertical cabinet shell 5, so that the mounting holes around the cover plate are aligned with the internal threaded holes on the shell frame, and use a multi-point symmetrical fastening method to screw in the countersunk screws one by one until the back sealing cover plate 4 and the vertical cabinet shell 5 are tightly fitted, finally completing the physical enclosure and protection of the internal accommodating space.

[0031] Figure 4 This is a schematic diagram illustrating the modular storage unit and the composition of the electronic ink display table sign workstation according to an embodiment of this application. Figure 4As shown, it includes a modular storage unit 3(a) and an e-ink display nameplate 3(b). Specifically, since the e-ink display nameplate 3(b) is a precision display device, in large-scale centralized management scenarios, without independent physical isolation space, it is highly susceptible to screen scratches and casing damage from disorderly stacking. Furthermore, the lack of a guiding structure makes it difficult to support subsequent efficient blind insertion operations and electrical connection stability. Therefore, an array-type support frame 2 is vertically housed within the internal space of the vertical cabinet shell 5. Multiple modular storage units 3(a) are matrix-installed on the array-type support frame 2 along the horizontal and vertical directions. The front opening of each modular storage unit 3(a) is aligned with a pre-reserved opening on the panel of the vertical cabinet shell 5 to form a channel for inserting the e-ink display nameplate 3(b), thereby constructing a high-density independent protective matrix and a standardized mechanical guiding interface. This ensures that each e-ink display nameplate 3(b) has its own dedicated physical space, completely eliminating the risk of collisions between devices. At the same time, the aligned channel structure provides operators with clear visual and tactile feedback, greatly improving the accuracy and smoothness of batch access operations. In a specific example of this application, the assembler first slides the metal array-type support frame 2 into the inner cavity of the vertical cabinet shell 5, and uses the bottom positioning pins and the side wall reinforcing ribs for multi-point limiting and fixing to establish the vertical support benchmark; then, according to the preset row and column coordinates, the prefabricated multiple modular storage compartment units 3(a) are fastened one by one to the horizontal and vertical beams of the array-type support frame 2 with buckles or screws, and the depth position of each unit is finely adjusted until the front guide opening of the modular storage compartment unit 3(a) is tightly fitted to the corresponding rectangular hollow edge on the inner side of the front panel of the vertical cabinet shell 5; finally, the calibration mold is inserted into each channel in sequence to detect and calibrate the coaxiality of the modular storage compartment unit 3(a) and the opening of the shell panel, eliminating assembly tolerances, thereby forming a standardized channel system with neat matrix arrangement and uniform insertion and removal resistance.

[0032] Furthermore, since this workstation adopts a tall, upright structure to maximize space utilization, operators primarily maintain a standing posture when configuring and monitoring the status of batch equipment. If the interactive interface is placed horizontally on the top or vertically against a high side, the poor viewing angle will lead to severe screen glare, limited visibility, and neck muscle fatigue, not only reducing human-computer interaction efficiency but also failing to meet the ergonomic requirements for long-term continuous operation. Therefore, in this application, by fixing the top control panel cover 6 to the top surface of the upright cabinet shell 5 and embedding the touch interaction terminal 1 into the inclined surface of the top control panel cover 6, tilting it towards the operator, an integrated interactive control platform conforming to the ergonomic golden viewing angle is constructed. This ensures that the operator can obtain the best unobstructed viewing angle and touch operation plane from a natural standing position, while the upward-raised cover structure provides the necessary physical support and under-screen wiring space for the precision display components. Specifically, in one particular example of this application, the assembler first opens data cable harness through holes and mounting positioning holes on the top bearing surface of the vertical cabinet shell 5, aligns the one-piece injection-molded top console cover 6 with this area, and uses hexagonal bolts to pass through the flange at the bottom of the cover to firmly lock it to the top of the vertical cabinet shell 5, establishing a stable structural foundation; then, the power supply and communication cables of the touch interactive terminal 1 are passed through the rectangular embedding groove reserved on the inclined surface of the top console cover 6 and led to the central control unit inside the cabinet, and then the screen assembly of the touch interactive terminal 1 is smoothly embedded into the inclined groove, and reverse-locked by the metal pressure strip on the back or the threaded fastener on the side, and finally, a waterproof sealing strip is pressed into the seam between the screen edge and the cover to complete the overall assembly of the human-computer interaction terminal with a specific tilt angle.

[0033] Furthermore, since this workstation involves real-time concurrent control and centralized power supply of a massive array of nodes, using discrete external controllers or complex point-to-point wiring architectures would not only lead to signal attenuation and delay but also generate extremely high electromagnetic interference and wiring maintenance difficulties within the cabinet, failing to meet the high reliability requirements of industrial applications. Therefore, in the technical solution of this application, the central control unit is placed inside the vertical cabinet shell 5 and electrically connected to the touch interaction terminal 1 and each modular storage compartment unit 3(a) via power supply and data buses, respectively, thereby constructing an electrical neural network based on an embedded main control hub and bus topology architecture. This ensures that logical instructions and power flow are efficiently distributed from the brain to the end within a physically protected shielded space, guaranteeing that the human-machine instructions of the touch interaction terminal 1 can be parsed in milliseconds and accurately synchronized to any designated modular storage compartment unit 3(a), achieving integrated hardware and software collaborative operation. Specifically, in one particular example of this application, the technician first fixes the central control unit PCB board, which integrates the microprocessor and power management module, to the back panel mounting position inside the vertical cabinet shell 5 using insulating pillars, and connects heat dissipation components to ensure the thermal stability of the core computing power; then, a composite power supply and data bus backbone cable with an electromagnetic shielding layer is laid along the internal frame, one end of the bus is connected to the communication output interface of the central control unit, and the other end extends upward through the cable hole of the top cover to connect to the LVDS or HDMI signal port and power supply port of the touch interactive terminal 1. At the same time, the branch lines of the bus are connected to the integrated circuit interface at the back end of each modular storage compartment unit 3(a) one by one through the back panel cascade or star distribution, thereby completing the physical connection of the power supply circuit and data communication link inside the entire workstation.

[0034] More specifically, since the e-ink display table card 3(b) is an electrically powered smart terminal, it still requires regular physical charging and maintenance in wireless transmission mode. Furthermore, in a dense array of hundreds of highly homogeneous displays, the tiny text on the screen alone cannot support rapid visual positioning and accurate distribution over long distances. Without an automated electrical access mechanism and intuitive physical guidance, the efficiency and accuracy of large-scale deployment will be severely hampered. By providing flexible metal contacts deep within each modular storage unit 3(a) and visual positioning indicator lights on the outer panel of each modular storage unit 3(a), and configuring the metal pads at the rear of the e-ink display table card 3(b) to physically contact the flexible metal contacts of the modular storage unit 3(a) when the e-ink display table card 3(b) is fully inserted into the modular storage unit 3(a), the e-ink display table card 3(b) is integrated into the power supply and data bus network. This constructs an electromechanical coupling interface integrating blind-plug charging, wired data return, and physical light effect indexing. In actual operation, when the e-ink display table card 3(b) is pushed along the guide rail to the bottom, the flat metal pad at its tail overcomes the elastic resistance and presses against the elastic metal contacts. The preload of the spring breaks the oxide layer on the metal surface to establish a low-impedance physical connection, which triggers the handshake protocol of the underlying circuit. This not only activates the charging circuit but also enables the system to light up the visual positioning indicator to provide feedback on the connection status or respond to subsequent positioning commands. In this way, a stable power and communication link is automatically established when the device is in place, eliminating the burden of manual wiring. An external light source is used to convert digital addressing commands into clear physical spatial guidance, realizing a highly efficient operation and maintenance closed loop of plug-and-play and instant access.

[0035] Figure 5 This is a data processing flowchart of the central control unit in an array-type e-ink screen nameplate workstation according to an embodiment of this application. Figure 5As shown, the data processing procedure of the central control unit includes the following steps: S100, in response to the hardware connection action of the electronic ink screen nameplate being connected to the modular storage compartment unit, the unique device identifier of the electronic ink screen nameplate is read through the power supply and data bus, and the unique device identifier is bound and mapped with the physical slot coordinates of the modular storage compartment unit to obtain the slot device topology mapping table; S200, based on the externally input participant list data, the slot device topology mapping table is used to perform node allocation and image rendering calculation on the participant list data to obtain the device display update data stream; S300, the device display update data stream is distributed to the corresponding electronic ink screen nameplates through the power supply and data bus. The e-ink table card refreshes the screen and generates a system ready status flag after confirming that the data writing is complete and the screen display is updated; S400, in response to the retrieval command initiated by the user terminal under the activation of the system ready status flag, the target object information carried by the retrieval command is used to perform reverse addressing operation in the slot device topology mapping table to parse the physical address of the target device and generate a positioning control electrical signal; S500, the positioning control electrical signal is loaded into the driving circuit of the visual positioning indicator corresponding to the physical address, and the light-emitting element is driven to perform a preset flashing action by controlling the current to output a physical guiding light effect indicating the specific storage location of the target device.

[0036] Specifically, in step S100, in response to the hardware connection action of the e-ink screen table card connecting to the modular storage unit, the unique device identifier of the e-ink screen table card is read through the power supply and data bus, and the unique device identifier is bound and mapped with the physical slot coordinates of the modular storage unit to obtain the slot device topology mapping table. It should be understood that since the e-ink screen table card 3(b) is a mobile and usable discrete terminal, its return to the warehouse has a great deal of randomness and disorder. If the control system lacks the ability to perceive the correspondence between digital identity and physical location in real time, it will lose the basis for point-to-point precise control and physical positioning guidance of specific devices, causing the system to degenerate into a blind control state that cannot be addressed. Therefore, in the technical solution of this application, the central control unit is configured to respond to the hardware connection action of the e-ink screen table card 3(b) connecting to the modular storage compartment unit 3(a), read the unique device identifier of the e-ink screen table card 3(b) through the power supply and data bus, and bind and map the unique device identifier to the physical slot coordinates of the modular storage compartment unit 3(a), thereby building a real-time index database that dynamically follows the changes in hardware position at the software level. In this way, the disordered stacked physical devices can be transformed into precisely addressable digital matrix nodes, ensuring that subsequent image data streams and control commands can be accurately routed to each specific e-ink screen table card 3(b) specified in the physical space.

[0037] More specifically, in a specific example of this application, the central control unit continuously monitors the electrical characteristic changes of the ports of each modular storage unit 3(a) using a polling scan or interrupt triggering method. Once a level jump or impedance loading signal is detected due to metal contact contact at a specific physical address (e.g., the interface in row X and column Y), the coordinates of the physical slot are immediately locked and the device identification process is triggered. Subsequently, the central control unit sends a handshake command to the specific active port through the power supply and data bus, and reads the MAC address or serial number pre-stored in the internal register of the connected e-ink screen table card 3(b) as the unique identifier of the device. Finally, the processor logic of the central control unit uses the obtained unique identifier of the device as the key value and the physical slot coordinates of the current triggering port as the attribute value to generate a one-to-one corresponding association record and write it into the slot device topology mapping table in the system memory, thus completing the initial registration of the storage node.

[0038] Specifically, in step S200, based on the externally input participant list data, the slot device topology mapping table is used to perform node allocation and image rendering calculations on the participant list data to obtain the device display update data stream. It should be understood that since the participant list data is essentially plain text-formatted business information, and the e-ink screen nameplate 3(b), as a dot-matrix display device, requires specific pixelated image data to drive screen refresh, and initially, business personnel do not know the specific location of each physical device, without an intermediate layer for converting logical data to physical hardware, accurate content delivery and format compatibility cannot be achieved. Therefore, by configuring the central control unit to perform node allocation and image rendering calculations on the participant list data based on the externally input participant list data using the slot device topology mapping table, a transcoding and routing distribution mechanism from the abstract business list to concrete hardware control instructions is constructed. This ensures that each piece of personnel information can be accurately assigned to a known, connected physical node, and the text information is preprocessed into an image signal that the device can directly parse, laying the data foundation for subsequent batch writing.

[0039] More specifically, in a specific example of this application, the processor of the central control unit first parses the imported participant list data to extract key fields such as name and job title, and traverses the slot device topology mapping table in memory to obtain a list of unique device identifiers for all currently online devices; then, the processor matches each person entry in the list to an available unique device identifier according to a preset linear or priority rule, thereby establishing the correspondence between people and devices at the logical level; next, it calls the built-in graphics rendering engine to rasterize the text characters into bitmap data adapted to the resolution of the e-ink screen nameplate 3(b) according to a preset layout template, and finally encapsulates the bitmap data with the corresponding device target address and check code, and serializes it to generate a device display update data stream that conforms to the power supply and data bus transmission standards.

[0040] In particular, in the context of large-scale concurrent processing of array-type e-ink screen nameplate workstations, the aforementioned implementation method for node allocation and image rendering calculation of the participant list data adopts a naive linear sequential mapping strategy. That is, according to the input order of the participant list, the data is mechanically allocated one by one to the physically continuous array of nameplates. This processing method has serious blind spots and ergonomic disconnect at the level of physical entity interaction. Specifically, this mechanism not only ignores the objective spatial potential energy differences of the physical cabinet itself, but also fails to consider the inherent semantic weight fluctuations of the business data itself. From a spatial physical perspective, standard cabinets exhibit a significant vertical height layout (typically spanning 20cm to 160cm from the ground). Ergonomic research shows that the area within the line of sight of the human body from waist to chest height is the golden interaction zone, where visual capture efficiency is the highest and physical grasping posture is the most comfortable; conversely, slots at the bottom of the cabinet require operators to crouch to retrieve them, while the top edge may require tiptoeing. These areas have naturally high resistance properties. The original mechanism's random or linear allocation might result in VIP guests (those requiring the highest priority and most prestigious presentation) having their nameplates relegated to dusty corners, while ordinary attendees occupy prime spots. This significant mismatch of physical resources not only reduces the efficiency of distributing important materials but also leads to a poor user experience. From a data semantic perspective, the attendee list is not flat data; it implicitly contains strong hierarchical attributes (such as guest identity and job level) and clustering attributes (such as belonging to the same department or table). The original mechanism lacks in-depth mining and utilization of this metadata, resulting in high-value data failing to obtain high-value physical location mappings. Furthermore, related data is physically discretized (nameplates of attendees at the same table are scattered at opposite ends of the rack), making batch and continuous retrieval impossible. This disregard for the binary relationship between physical engineering and data semantics leaves the entire workstation in a state of intelligent mismatch when deployed for high-profile meetings.

[0041] To address the aforementioned shortcomings, in a preferred embodiment of this application, a resource scheduling optimization mechanism based on adaptive matching of physical engineering potential energy fields and semantic weights is constructed. This mechanism utilizes a slot device topology mapping table to perform node allocation and image rendering calculations on the participant list data, thereby implementing bidirectional quantification and optimal solution of physical space value and data semantic value. This transforms subjective operational comfort and personnel importance into a computer-executable mathematical model, ensuring that the e-ink screen nameplates 3(b) of important personnel automatically appear at the most easily accessible golden height level, and that devices from the same department automatically cluster in adjacent physical areas, thus significantly reducing the workload of material distribution and improving overall deployment efficiency.

[0042] More specifically, in another specific example of this application, Figure 6 This is a data processing flowchart for node allocation and image rendering calculation of meeting list data in an array-type e-ink screen nameplate workstation according to an embodiment of this application. The central control unit further includes the following steps: S210, using the physical coordinate data in the slot device topology mapping table and preset ergonomic height parameters, performing space efficiency evaluation calculations on each modular storage unit to generate an ergonomic value matrix; S220, based on the preset personnel priority attributes and ergonomic value matrix in the meeting list data, performing utility-maximizing adaptive allocation of the meeting list data and modular storage units using a greedy strategy to obtain an optimized allocation mapping table that establishes the correspondence between personnel and equipment; S230, performing differential rendering and data stream protocol encapsulation on the optimized allocation mapping table to obtain the device display update data stream.

[0043] Accordingly, in step S210, the physical coordinate data in the slot equipment topology mapping table and the preset ergonomic height parameters are used to perform a space performance evaluation calculation for each modular storage unit to generate an ergonomic value matrix. It should be understood that, since traditional physical storage slots are only represented as indistinguishable coordinate points in the data structure, and computers cannot directly perceive the differences in ease of human operation caused by different heights and positions in the physical space, without an intermediate evaluation layer to transform intuitive usability into a rational numerical value that the computer can calculate, subsequent scheduling algorithms will be unable to identify the gradient of the quality of physical resources. Therefore, in the technical solution of this application, the physical coordinate data in the slot equipment topology mapping table and the preset ergonomic height parameters are used to perform a space performance evaluation calculation for each modular storage unit to generate an ergonomic value matrix, thereby performing the steps of multi-dimensional feature quantification reconstruction and physical ergonomic field establishment. In this way, a digital evaluation system that accurately describes the distribution of physical space value can be constructed through the Gaussian decay model, giving the originally homogeneous physical slots differentiated value potential energy, thereby establishing the necessary calculation benchmark for solving the problem of allocating limited high-quality physical resources.

[0044] In this embodiment, the central control unit controls each physical slot in the rack array. Define and calculate its ergonomic comfort index. Specifically, the space efficiency of each modular storage unit is evaluated and calculated using the following formula: ;in, This indicates the vertical height level of slot i, that is, the row coordinate value of the modular storage unit. This is a preset optimal height threshold for human use, corresponding to the golden height level parameters between the waist and chest. The standard deviation of the Gaussian function is used to control the steepness of the comfort zone decay. The horizontal coordinate of slot i is the column coordinate value of the modular storage unit. The coordinates of the horizontal center of the cabinet; and These are the height weighting factor and the horizontal weighting factor, used to adjust the proportion of vertical height and horizontal field of view in the overall score. In this calculation, the first term of the formula utilizes a Gaussian function. Simulating the physical characteristics of the human comfort zone, thus achieving a distance from the optimal height. The score decreases rapidly and non-linearly with increasing distance, accurately depicting the difficulty gradient of physical operations. The second term of the formula uses an inverse proportional function to compensate for visual focus, resulting in higher score gains for slots closer to the horizontal center of the rack. It's worth noting that the ergonomic comfort indices of all slots are aggregated to form an ergonomic value matrix. This process essentially completes a digital potential energy model of the physical space, ensuring that the computing system can perceive, like a human, which areas are the golden zones for easy operation and which are the peripheral areas requiring additional physical effort.

[0045] Accordingly, in step S220, based on the pre-set personnel priority attributes and engineering value matrix in the participant list data, the participant list data and modular storage units are matched and allocated using a greedy strategy to maximize utility, thereby obtaining an optimized allocation mapping table that establishes the correspondence between personnel and equipment. It should be understood that, after clarifying the objectively existing differences in engineering value among different slots in the physical array, the core contradiction faced by the system transforms into the optimal matching problem between limited high-quality physical resources and differentiated personnel business needs. Considering the stringent constraints of computing power and real-time performance on the embedded main control environment, traditional global graph matching algorithms are difficult to implement due to their excessive complexity. Without an efficient and lightweight decision-making logic, the painstakingly quantified spatial value cannot truly serve high-value business objects. Therefore, in the technical solution of this application, the central control unit further matches and allocates the participant list data and modular storage units using a greedy strategy to maximize utility, thereby obtaining an optimized allocation mapping table that establishes the correspondence between personnel and equipment, and thus establishing an intelligent arbitration rule for who should occupy the prime location. This ensures that local optimal solutions can be found quickly under limited computing power, guarantees that the nameplates of important people will occupy the central position with the highest ergonomic value, and at the same time, tries to group the nameplates of the same group of people together in adjacent areas, thereby maximizing the overall operational efficiency of the system.

[0046] In this embodiment, considering the real-time requirements of the embedded main control unit, the central control unit adopts a modified greedy algorithm instead of the highly complex full-graph matching logic. The system first traverses the weighted queue of personnel and calculates the mapping of the j-th participant's data to the currently available slot set. The adaptation gain for the i-th slot is used to lock the optimal mapping relationship. The calculation process is represented by the following formula: ； in, This represents the index of the optimal physical slot selected for the j-th participant. This indicates iterating through the set of all modular storage units that are currently in an idle state. This indicates that the maximum value should be returned. This represents the priority weight of the j-th person, a value obtained by quantifying the VIP level or position field pre-set in the participant list data. The ergonomic comfort index of the i-th slot is calculated in the previous steps; This core product term expresses the total system utility gain resulting from matching high-importance personnel to high-comfort slots; This is a clustering distance penalty term used to measure the degree of physical spatial dispersion (e.g., Euclidean distance) between the current candidate slot i and other slots already assigned in that group when the person belongs to a specific group (such as the same department or the same round table). This is the clustering penalty coefficient, used to adjust the weight of spatial clustering in the overall decision. Driven by this formula, the algorithm logic forces the system to prioritize satisfying higher-weighted clustering. With large numbers This combination allows VIP nameplates to automatically occupy the most desirable height slots in the system, ensuring that important figures always occupy the most ergonomically valuable central position. The removal of penalties means the system strives to avoid scattering data from the same group of people across the physical array, grouping nameplates of the same group together in adjacent areas. This mathematically achieves intelligent physical scheduling, ensuring that important equipment is easily accessible and related equipment is accessed simultaneously. This establishes a list of specific slot IDs corresponding to each person, resulting in an optimized allocation mapping table.

[0047] Accordingly, in step S230, the optimized allocation mapping table is differentially rendered and encapsulated with a data stream protocol to obtain the device display update data stream. It should be understood that after establishing the correspondence between personnel and devices, the system faces the concurrent task of sending image data to hundreds of e-ink screen nameplates in the array. If the full bitmap file is mechanically broadcast to all devices, it will instantly generate a huge instantaneous data throughput, exceeding the bandwidth capacity of the power supply and data bus, leading to severe communication congestion and screen refresh delays. This causes the upper-layer intelligent scheduling strategy to fail due to the underlying transmission bottleneck. Therefore, in the technical solution of this application, the central control unit further performs differential rendering and data stream protocol encapsulation on the optimized allocation mapping table to obtain the device display update data stream, thereby executing a transmission optimization strategy based on source data slimming. This compresses the effective payload to be transmitted to a theoretical minimum, ensuring real-time instruction delivery in high-density concurrent scenarios, and enabling the optimized physical allocation results to be quickly and synchronously implemented as physical screen refresh actions.

[0048] This technical solution aims to fundamentally address the technical challenge of the disconnect between physical operation experience and data management logic in large-scale electronic nameplate management. By incorporating the physical constraints of ergonomics and the semantic features of business logic into mathematical modeling, it achieves intelligent and humanized resource allocation. The direct technical effects are: VIP nameplates automatically appear at the most easily accessible height; nameplates from the same department automatically cluster in adjacent areas, significantly reducing the physical search path for meeting staff and the frequency of high-intensity actions such as bending over and tiptoeing, thus significantly improving the physical efficiency of material distribution. Simultaneously, differential data stream processing effectively reduces bus load, ensuring real-time system response under large-scale array operations, ultimately constructing a highly efficient workstation system that understands both data logic and physical operation experience.

[0049] Specifically, in step S300, the device display update data stream is distributed to the corresponding e-ink display table card via the power supply and data bus for screen refresh. After confirming that the data writing is complete and the screen display is updated, a system ready status flag is generated. It should be understood that since the e-ink display table card 3(b) uses bistable display technology, its screen refresh process involves a physical and chemical change process driven by voltage waveforms, which takes much longer than the data transmission time. Furthermore, incomplete data writing or drive interruption will cause screen ghosting or even screen distortion. Therefore, the system must establish a strict closed-loop feedback mechanism to confirm the final physical display state, and cannot determine the task's end simply based on the completion of data transmission. Therefore, in the technical solution of this application, the central control unit distributes the device display update data stream to the corresponding e-ink display table card via the power supply and data bus for screen refresh, and generates a system ready status flag after confirming that the data writing is complete and the screen display is updated, thereby implementing end-to-end data integrity verification and physical execution status monitoring. In this way, it can be ensured that the system will only declare itself ready for use after all the e-ink table cards 3(b) have successfully restored the received differential data into a complete image and completed the screen particle flipping action, thus eliminating the risk of incorrect delivery of display and content due to communication packet loss or refresh failure.

[0050] More specifically, in a specific example of this application, the central control unit uses the broadcast mechanism of CAN bus or RS485 protocol to inject the serialized device display update data stream into the power supply and data bus network. The local controller of each e-ink screen table card 3(b) captures the data packet matching its own ID and stores it in the display memory, and then starts the electrophoresis drive process of the e-book capsule. During this period, the central control unit enters the polling listening mode and receives the ACK confirmation frame and screen status register value returned by each device after the refresh is completed. Once the number of devices that have returned confirmation is consistent with the target number of this task, the central control unit immediately sets the system ready status flag in the system memory and may link the touch interactive terminal 1 to pop up the prompt message "Update complete, please use", marking the completion of the synchronization between the physical and digital worlds.

[0051] Specifically, in step S400, in response to a retrieval command initiated by the user terminal under the activation of the system ready state flag, the target object information carried by the retrieval command is used to perform a reverse addressing operation in the slot device topology mapping table to resolve the physical address of the target device and generate a positioning control electrical signal. It should be understood that in large-scale array storage scenarios, even if all devices have completed content updates, operators facing hundreds of uniformly shaped modular storage units 3(a) still cannot quickly establish an intuitive connection between the names of attendees and their specific physical locations by visual inspection. Without a reverse guidance mechanism, the retrieval process will degenerate into an inefficient, one-by-one search. Therefore, in the technical solution of this application, in response to a retrieval command initiated by the user terminal under the activation of the system ready state flag, the target object information carried by the retrieval command is used to perform a reverse addressing operation in the slot device topology mapping table to resolve the physical address of the target device and generate a positioning control electrical signal, thereby constructing a precise reverse index from the business logic layer to the physical driving layer. In this way, abstract requests for searching a person's name can be instantly transformed into specific hardware coordinate driving instructions, eliminating the cognitive burden of manual memorization or searching, and achieving intelligent positioning that provides exactly what you search for.

[0052] More specifically, in a specific example of this application, when an operator enters a person's name in the search bar of the touch interactive terminal 1 and clicks confirm, the generated retrieval instruction is transmitted to the central control unit. The processor first verifies the system ready status flag to ensure data consistency, and then uses the unique identifier of the device bound to the person's name as the index key to perform a hash lookup in the memory-resident slot device topology mapping table, matching the physical slot coordinates (e.g., Row-5, Col-8) of the device in milliseconds. The processor then converts the logical coordinates into the underlying GPIO control level or bus addressing code, generating a positioning control electrical signal sufficient to drive the action of a specific hardware circuit, thus preparing the electrical system for the subsequent lighting operation.

[0053] Specifically, in step S500, a positioning control electrical signal is loaded into the driving circuit of the visual positioning indicator corresponding to the physical address. By controlling the current flow, the light-emitting element is driven to perform a preset flashing action, thereby outputting a physical guiding light effect indicating the specific storage location of the target device. It should be understood that since the physical address parsed at the logical level is merely a set of digital coordinates existing within the processor, for operators in the physical space, without an intuitive visual medium, manually locating the target device in a large array of cabinets based solely on the row and column values ​​displayed on the screen is highly susceptible to visual fatigue, leading to errors in counting rows or columns and failing to complete the final step from digital retrieval to physical capture. Therefore, in the technical solution of this application, a positioning control electrical signal is further loaded into the driving circuit of the visual positioning indicator corresponding to the physical address. By controlling the current flow, the light-emitting element is driven to perform a preset flashing action, thereby outputting a physical guiding light effect indicating the specific storage location of the target device. This implements a photoelectric conversion strategy that transforms the invisible internal logical state into a visible external physical landmark. This enables an electronic tag lighting and selection mechanism that aligns with the human eye's visual search instincts. Operators can instantly lock onto the location of the illuminated point simply by relying on visual physiological reflexes, without needing to perform mental coordinate transformations, thus greatly improving the detection speed and accuracy in dense arrays.

[0054] More specifically, in a specific example of this application, the central control unit first routes the positioning control electrical signal precisely to the LED driver chip pin of the target modular storage compartment unit 3(a) via a multiplexer or serial shift register, and outputs a pulse width modulation (PWM) waveform signal with a specific duty cycle. This signal acts on the gate of the power switch (such as a MOSFET) in the drive circuit, controlling the conduction circuit to periodically turn on and off the constant current flowing through the light-emitting diode at a preset frequency (e.g., 2Hz), thereby driving the visual positioning indicator to emit a high-brightness rhythmic flashing beam. This dynamically changing physical guiding light effect creates a strong visual contrast among many static or off background lights, accurately guiding the operator's hand movements directly to the specific location of the target device.

[0055] In summary, the array-type e-ink screen nameplate workstation according to the embodiments of this application is explained. By constructing an array-type storage matrix with electrical sensing capabilities, it automatically establishes a topological mapping between physical coordinates and device IDs upon device access, thereby incorporating discrete hardware entities into a unified digital management domain and solving the problems of cumbersome charging and lack of protection. Addressing the challenge of physical positioning, the system utilizes reverse addressing logic to drive visual signage next to the slots, translating the software's search intent into real-time light effect guidance in the physical space. More importantly, an adaptive scheduling strategy based on ergonomic potential energy and business semantic weights is introduced at the data distribution layer. By calculating the comfort gradient of physical slots and the value level of personnel data, it intelligently guides high-priority tasks to the optimal operating area, achieving a closed-loop process and maximizing efficiency from batch data refresh to physical entity delivery.
