Description

Technical Field

[0001] This application generally relates to the field of shelving technology. More specifically, this application relates to a sliding rail shelving metering system and a power asset management method applied to a power system terminal warehouse. Background Technology

[0002] With the deepening of smart grid construction and the increasing requirements for asset lifecycle management, power system end-point warehouses (such as power supply stations and metering centers) have placed unprecedented demands on the storage management of metering assets such as electricity meters and instrument transformers. These assets have strict one-item-one-code traceability characteristics, and their entry, exit, and inventory operations are frequent. Traditional methods relying on manual counting and paper records are no longer sufficient to meet the needs of high-efficiency and zero-error operation.

[0003] Currently, automated racking technology applied to general warehousing reveals the following pressing technical bottlenecks when dealing with the special scenarios of electricity metering asset management: First, in terms of system architecture and control logic, a centralized control mode is generally adopted. The judgment of all sensor signals and the generation of execution instructions all rely on a central processing unit, resulting in sluggish response when the system handles concurrent tasks at multiple storage locations (such as real-time inventory checks of the entire warehouse), forming a performance bottleneck. At the same time, the failure of this central unit will cause the entire system to shut down, resulting in insufficient reliability and scalability.

[0004] Secondly, regarding the accuracy and real-time nature of information management, existing solutions often only achieve simple detection-scanning linkage, lacking mandatory real-time binding and cross-verification of asset identity, storage location physical status (whether the asset exists), and system display status. This makes the "account, asset, and location" information prone to deviations during frequent manual and automated interactions, failing to guarantee the accuracy required for power asset management.

[0005] In view of this, there is an urgent need to provide a sliding rail rack metering system and power asset management method for use in power system terminal warehouses, so as to improve concurrent processing capabilities and the accuracy of asset information binding with storage locations. Summary of the Invention

[0006] In order to at least solve one or more of the technical problems mentioned above, this application proposes a sliding rail rack metering system and power asset management method for power system terminal warehouses with strong processing capabilities and high operational accuracy.

[0007] In a first aspect, this application provides a sliding rail rack metering system for a power system terminal warehouse, comprising a rack body having multiple storage layers, and further comprising: a layered control system, which includes sub-control modules disposed on each of the storage layers, and a main control module communicatively connected to all the sub-control modules; a status sensing and indication system, which includes sensing modules disposed on each storage location of each storage layer and a display module corresponding to the signals of the sensing modules, wherein the sensing modules are used to detect whether there are assets placed in the corresponding storage location and generate sensing signals; and multiple moving scanning systems, each... The mobile scanning system includes a barcode scanning device slidably mounted above each shelf and driven by a sub-control module of that shelf. The sub-control module is configured to: receive and process the sensing signals from each storage location on that shelf, control the barcode scanning device on that shelf to move to the target storage location to scan the asset barcode, and bind and verify the scanned asset information, the sensing signal of the corresponding storage location, and the status of the display module. The main control module is configured to: communicate with a host computer to receive task instructions containing asset information, distribute the task instructions to the sub-control module where the target storage location is located, and coordinate cross-layer tasks and overall shelf status management.

[0008] In some embodiments, the main control module is located on the shelf near the top cover; the signals of each sub-control module are led out through the lines located inside the side columns of the shelf, and the lines of each layer are connected in parallel inside the columns, then aggregated upwards and connected to the main control module.

[0009] In some embodiments, the mobile scanning system includes: a slide rail mechanism disposed within a storage layer, wherein a synchronous belt is disposed within the slide rail mechanism; a slider connected to a drive motor and engaging with the synchronous belt; a barcode scanning device mounted on the slider; a storage location sensor disposed on the slider and used to identify a specific storage location; and a cable chain for storing cables; one end of the cable chain is fixed, and the other end is connected to the slider and moves with it; the sub-control module controls the drive motor to drive the slider and the barcode scanning device and storage location sensor on it to reciprocate along the slide rail via the synchronous belt.

[0010] In some embodiments, the moving scanning system further includes two limit position sensors for detecting the limits of slider movement.

[0011] In some embodiments, the cables integrated within the drag chain include at least a power line, a data line, a signal line, and a motor control line connected to the sub-control module, wherein the power line is used to power the barcode scanning device; the data line is used to transmit the scanning data of the barcode scanning device; the signal line is used to transmit the detection signals of the storage positioning sensor and the extreme position sensor; and the motor control line is used to transmit control signals to the drive motor.

[0012] In some embodiments, the slide rail mechanism is provided with a storage position sensing bar, and the storage position sensing bar is provided with a plurality of mechanical positioning structures for identifying the storage position along its length direction; a storage position positioning sensor that cooperates with the mechanical positioning structure is installed on the slider, and the storage position positioning sensor is used to detect the mechanical positioning structure during movement and generate an electrical signal that identifies the center of a specific storage position; the storage position positioning sensor is electrically connected to the sub-control module.

[0013] In a second aspect, this application provides a power asset management method based on the aforementioned sliding rail rack metering system applied to the end warehouse of a power system. The warehousing method includes the following steps: in response to an asset being placed in a target storage location, the sensing module of the storage location is triggered; the sub-control module of the layer where the storage location is located receives the trigger signal and controls the barcode scanning device to move above the target storage location to perform barcode scanning; the sub-control module binds the successfully scanned asset barcode information with the identification information and sensing signal of the target storage location to form an warehousing record; the sub-control module or the main control module controls the display module of the target storage location to display the successful warehousing status and uploads the warehousing record.

[0014] In some embodiments, the outbound method includes the following steps: the main control module receives an outbound instruction from a host computer, the instruction containing target asset information; the main control module determines the shelf, layer, and storage location of the asset based on the asset information; the main control module triggers a global indicator light on the target shelf and sends a guidance instruction to the sub-control module on the layer where the target storage location is located; the sub-control module drives the display module of the target storage location to light up in a preset guidance mode according to the guidance instruction to provide visual guidance for picking up goods; in response to the change in the state of the sensing module caused by the asset being taken away, the sub-control module confirms that the outbound process is complete and updates the status.

[0015] In some embodiments, the power asset inventory method includes the following steps: the main control module receives an inventory instruction from the host computer and synchronously sends an inventory start signal to all sub-control modules of all layers; each sub-control module controls the barcode scanning device of its layer to move to each storage location of its layer in a preset order for barcode scanning; for each storage location, the sub-control module compares and verifies the barcode scanning result with the current state of the sensing module of that storage location; each sub-control module uploads the verified inventory data to the main control module, which then summarizes and generates a complete list of shelf assets.

[0016] In some embodiments, when the scanning device fails to scan the target storage location for the first time, the sub-control module controls the scanning device to perform a preset number of retry scans; the retry scan includes controlling the scanning device to alternately shift its position in a first direction and then in the opposite second direction before scanning again; if it still fails after reaching the maximum number of retry attempts, the storage location is marked as abnormal and reported.

[0017] In some embodiments, a physical mark is respectively provided on the outer side of the mechanical positioning structure at both ends of the slide rail mechanism; the origin calibration method includes the following steps: the sub-control module controls the drive motor to drive the slider to move along the first direction and the second direction respectively; when the slider detects a physical mark set on the slide rail for the first time during the movement along the first direction, the first position information is recorded; the slider is controlled to move along the second direction until another physical mark is detected, and the second position information is recorded; the position determined based on the second position information is set as the coordinate origin of the scanning device movement; after the origin calibration is completed, the sub-control module calculates the driving amount required to control the scanning device to move to any target storage location based on this coordinate origin and the known spacing between each storage location.

[0018] In some embodiments, the physical marker has a first distance from the nearest mechanical positioning structure, and a second distance between two adjacent mechanical positioning structures, and the first distance and the second distance are different; the detection of the physical marker is based on the difference in signal time characteristics generated when the sensor detects the mechanical positioning structure and the physical marker during movement.

[0019] In some embodiments, when the positioning signal of the storage location sensor fails, the drive motor is controlled to move the slider along the slide rail; when the slider triggers the limit position sensor located at the end of the slide rail stroke, the drive motor is controlled to stop; the slider is controlled to move from the position where the limit position sensor is triggered towards the center of the slide rail; during the movement of the slider in the center direction, two physical marks on the slide rail mechanism are detected by the storage location sensor on the slider; when the sensor detects two physical marks in sequence, the position of the detected second physical mark is taken as the origin of the coordinates.

[0020] The sliding-rail rack metering system for power system terminal warehouses, as described above, achieves a hierarchical control structure with a central control module and sub-control modules. The central control module receives tasks from a host computer and distributes them to the target sub-control modules. Each sub-control module focuses on processing signals within its own layer, resulting in precise task transmission, efficient cross-layer collaboration, and timely local control. This significantly improves the orderliness and responsiveness of the entire power metering asset management process. Furthermore, the sub-control modules in this application bind and verify the scanned asset information, the corresponding storage location's sensor signal, and the display module's status, thereby ensuring the accuracy of the asset information's binding to the storage location.

[0028] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 As shown, in some embodiments, this application provides a sliding rail rack metering system for a power system terminal warehouse, including a rack body 100, the rack body 100 having multiple storage layers 103, and further including: a layered control system, which includes a sub-control module 108 disposed in each of the storage layers 103, and a main control module 109 communicatively connected to all the sub-control modules 108; a status sensing and indication system, which includes a sensing module 112 disposed in each storage location of each storage layer 103 and a display module 119 corresponding to the signal of the sensing module 112, wherein the sensing module 112 is used to detect whether there is an asset 200 placed in the corresponding storage location and generate a sensing signal; multiple moving... The mobile scanning system includes a scanning device slidably mounted above each shelf 103 and driven by the sub-control module 108 of that shelf. The sub-control module 108 is configured to receive and process the sensing signals of each storage location on the shelf, control the scanning device on the shelf to move to the target storage location to scan the asset 200 barcode, and bind and verify the scanned asset 200 information, the sensing signal of the corresponding storage location, and the status of the display module 119. The main control module 109 is configured to communicate with the host computer to receive task instructions containing asset 200 information, distribute the task instructions to the sub-control module 108 where the target storage location is located, and coordinate cross-layer tasks and the overall status management of the shelf 100.

[0030] In this application, the sliding rail rack metering system (hereinafter referred to as the metering system) applied to the terminal warehouse of the power system is specifically designed for power assets 200, such as single-phase energy meters, three-phase energy meters, concentrators, metering terminals, and instrument transformers. It can realize intelligent control of the entire process of asset 200 warehousing, inventory, outbound, task assignment, and process management. The rack 200 includes a top cover 101, a bottom frame 107, side panels 104, and uprights 105. Multiple storage layers 103 are provided between the top cover 101 and the bottom frame 107, and rack indicator lights 102 are provided on the outer surface of the side panels 104. Four support bases 106 supporting the rack body 100 are provided at the corner below the bottom frame.

[0031] It is worth noting that the layout of the shelving 100's storage layers 103 in this solution is specifically designed based on the different size specifications of various types of assets 200. Single-phase energy meters and current transformers, due to their similar size specifications, each have 9 storage spaces on their respective storage layers 103. Three-phase energy meters, concentrators, and metering terminals, being larger in size, have 6 storage spaces on their respective storage layers 103, ensuring that all types of assets 200 receive suitable and organized storage space. It is also worth noting that the storage spaces are separated by dividers 133.

[0032] The shelving metering system of this solution includes a sub-control module 108 installed on each shelf 103, and a main control module 109 that is communicatively connected to all sub-control modules 108. The control signals of each shelf sub-control module 108 are connected in parallel and summarized by the main control module 109. The sub-control modules 108 are responsible for processing localized signals such as inbound, outbound, inventory, barcode scanning, and location display for their respective shelves. The main control module 109 is responsible for cross-layer task distribution, process management, and shelf number guidance when multiple shelves 100 are connected in parallel. At the same time, it establishes communication with the host computer to realize instruction reception and status uploading.

[0033] like Figures 5-8 As shown, the status sensing and indication system consists of a sensing module 112 and a display module 119 installed in each storage location. The sensing module 112 includes an infrared pressure plate 113, a moving block 114, a rear counterweight 115, an infrared sensor 116, and an infrared pressure plate control board 117. The infrared pressure plate 113 is externally enclosed in a housing 113-1, and the moving block 114 is fixed to the housing 113-1 via a rotating shaft 114-1. When the asset 200 is placed in the storage location, the moving block 114 is pressed down, triggering an infrared signal. After the asset 200 is removed, the rear counterweight 115 causes the moving block 114 to spring up, changing the signal and thus accurately detecting whether the asset 200 is placed in the storage location.

[0034] The display module 119 specifically consists of storage location labels installed at each storage location on the shelf 100. The labels are numbered using a combination of two sets of two-digit numbers. The first set of numbers corresponds to the layer number of the storage location, and the second set corresponds to the location number within that layer, allowing for intuitive location tracking of the asset 200. Furthermore, the storage location labels are driven by the rear display control board 119-1, illuminated by built-in RGB lights. Only the number portion of the label is translucent, clearly displaying the storage location number and laying the structural foundation for subsequent functions such as using light color to provide feedback on the storage status and operation results of the asset 200.

[0035] Multiple mobile scanning systems correspond one-to-one with each storage layer 103. Each mobile scanning system includes a scanning device that is slidably set above the corresponding storage layer 103. The scanning device consists of a scanning dock 124, a sensor assembly, a bracket 125, a horizontal movement limit wheel 127, and a signal control board 128. It is connected to a DC worm gear motor via a slide rail 122. The slider 121 drives the scanning dock 124 to move left and right to reach the target storage location and complete the scanning of the asset barcode 201.

[0036] like Figure 9 As shown, the barcode scanning device in this solution is adapted to the mobile scanning requirements of the slide rail 122. Its installation height and angle (mainly achieved through the setting of the bracket 125) have been precisely calibrated and set. That is, combined with the unified layout of each storage layer 103 storage location, the standard pasting position of the asset barcode 201, and the trajectory characteristics of the slider 121 driving the barcode scanning device to move, it is ensured that when the slider 121 drives the barcode scanning device to move above the center of any storage location, the scanning range 202 of the barcode scanning device can completely cover the pasting area of ​​the power metering asset barcode 201 in that storage location. This ensures that each scan can accurately capture the asset 200 barcode information, laying a stable foundation for the subsequent binding and verification of asset 200 information with storage location signals and display status.

[0037] In terms of functionality, the collaborative logic between the sub-control module 108 and the main control module 109 is clearly defined, forming a hierarchical control mechanism to jointly ensure the accurate operation of the system. The sub-control module 108 undertakes the core responsibility of localized control at this level: first, it receives and integrates all signals at this level, including the independent infrared pressure plate 113 sensing signals for each storage location, the front display signals, as well as storage location positioning signals, motor drive signals, and scanning dock 124 working signals, constructing a comprehensive verification data foundation. Subsequently, based on these signals, it controls the barcode scanning device at this level to accurately move to the target storage location, complete the asset 200 barcode scanning, and binds and verifies the scanned asset 200 information, the corresponding storage location's sensing signals, and the status of the display module 119 to ensure the consistency of all data.

[0038] It is worth noting that the sub-control module 108 in this solution determines the storage status of asset 200 through a core verification process. This involves verifying the consistency between the infrared pressure plate 113 sensing signal, the asset 200 barcode information, and the storage location label data to determine whether asset 200 is stored correctly and whether the operation is compliant. Based on this, the sub-control module 108 and the main control module 109 form a hierarchical control logic. According to the verification results, the indicator lights on the storage location labels are driven. If the three data match and the status is normal (e.g., successful warehousing, asset in storage location, compliant operation), a green label is lit. If data mismatch, abnormal operation (e.g., abnormal warehousing / outbound), or equipment failure occurs, a red label warning is triggered, achieving visual status verification. The main control module 109 focuses on global coordination and instruction transmission. It is mainly responsible for communicating with the host computer, receiving task instructions such as warehousing, outbound, and inventory checks containing asset 200 information, and accurately distributing these instructions to the sub-control module 108 where the target storage location is located. Simultaneously, it coordinates cross-level task execution and the overall status management of the shelving 100, ensuring efficient collaboration and standardized full-process control across all system components.

[0039] This application's solution employs a hierarchical control structure with a main control module 109 and sub-control modules 108. The main control module 109 connects to the host computer to receive tasks and distributes them to the target sub-control modules 108. The sub-control modules 108 focus on processing signals within their respective layers, achieving the beneficial effects of precise task transmission, efficient cross-layer collaboration, and timely local control. This significantly improves the orderliness and responsiveness of the entire process management of power metering assets 200. Simultaneously, during the processing of signals within their respective layers, the sub-control modules 108 in this application's solution bind and verify the scanned asset 200 information, the corresponding storage location's sensing signal, and the status of the display module 119. Through multi-dimensional data consistency verification, the accuracy of the asset 200 information and storage location binding is further ensured, making the entire asset 200 management process more rigorous and reliable.

[0040] In one specific implementation, the main control module 109 is located on the shelf layer 103 near the top cover 101; the signals of each sub-control module 108 are led out through the lines located inside the side columns 105 of the shelf 100, and the lines of each layer are connected in parallel in the columns 105, then aggregated upwards and connected to the main control module 109.

[0041] like Figure 2 As shown, in the solution of this application, the main control module 109 is integrated on the shelf 103 near the top cover 101, and together with the main power and host computer module 110 and DC power supply module 112 on the same shelf, it forms the core of the whole machine control, and together provides power support, communication guarantee and global management and control functions for the system operation.

[0042] In addition, all kinds of signals generated by the sub-control module 108 of each shelf 103 in this solution are passed through the pre-set round holes of the side column 105 of the shelf 100. The inside of the column 105 is specially designed with a groove structure, and the lines led out from each layer are arranged in parallel in an orderly manner in the groove to avoid the tangling of lines or signal interference. Then, they are collected layer by layer along the column 105 and finally achieve a stable connection with the main control module 109 in the top cover 101.

[0043] The signal transmission structure design provided by this solution not only ensures smooth communication between the sub-control modules 108 at each level and the main control module 109, but also makes the lines neat and orderly through the integrated layout of the columns 105.

[0044] like Figure 3 and Figure 4 As shown, in a specific embodiment, the mobile scanning system includes: a slide rail mechanism 122 disposed within the storage layer 103, wherein a synchronous belt is disposed within the slide rail mechanism 122; a slider 121 connected to a drive motor 120 and engaging with the synchronous belt; a barcode scanning device mounted on the slider 121; a storage location sensor 126 disposed on the slider 121 and used to identify a specific storage location; and a cable carrier 123 used to store cables; one end of the cable carrier 123 is fixed, and the other end is connected to the slider 121 and moves with it; the sub-control module 108 controls the drive motor 120 to drive the slider 121 and the barcode scanning device and the storage location sensor 126 thereon to reciprocate along the slide rail 122 via the synchronous belt.

[0045] In this application, the mobile scanning system is the core execution unit for achieving accurate scanning of assets 200. Besides the scanning device, it also includes at least a slide rail mechanism 122, a slider 121, a storage location sensor 126, and a drag chain 123. Specifically, the slide rail mechanism 122 is fixedly installed within each storage layer 103 as a basic support, and has a built-in synchronous belt that provides stable guidance for the movement of the slider 121 and also undertakes power transmission. The slider 121, as the core load-bearing component, establishes a power connection with the DC worm gear drive motor 120 and tightly engages with the synchronous belt within the slide rail 122 through a meshing structure. The scanning device, storage location sensor 126, scanning dock 124 signal control board 128, and horizontal movement limit wheel 127 are all integrated and installed on the slider 121, forming an integrated mobile scanning assembly to ensure synchronized operation and stable operation of all components.

[0046] To ensure neat cable layout and safe use, the system is also equipped with a dedicated cable chain 123, which is specifically designed to store various cables required during the movement of the slider 121. One end of the cable chain 123 is fixed to the frame of the shelf 100, and the other end is rigidly connected to the slider 121. It can move back and forth synchronously with the slider 121, completely eliminating problems such as cable pulling and wear.

[0047] In actual operation, the sub-control module 108 drives the DC worm motor to operate by outputting control signals. The power generated by the motor is transmitted to the slider 121 via a synchronous belt, causing the slider 121 and its components, such as the barcode scanning device and the storage location sensor 126, to move smoothly back and forth along the slide rail 122. During the movement, the storage location sensor 126 collects position signals in real time and feeds them back to the sub-control module 108. When the target storage location signal is detected, the sub-control module 108 immediately determines that the slider 121 has reached the target storage location, and then controls the motor to stop. The barcode scanning device simultaneously starts the barcode scanning operation, quickly completing the collection of asset 200 information. The entire movement and scanning process is precise, controllable, and highly efficient, providing a solid and reliable execution guarantee for the subsequent binding and verification of asset 200 information and storage location.

[0048] like Figure 4 and Figure 10 As shown, in one specific embodiment, the moving scanning system further includes two limit position sensors for detecting the movement limits of the slider 121.

[0049] In this application, the moving scanning system also includes two limit position sensors for detecting the movement limits of the slider 121, specifically a left limit sensor 129 and a right limit sensor 130. The installation positions of these two limit sensors are adapted to the left and right limit strokes of the slider 121, respectively.

[0050] During operation, when the sub-control module 108 drives the DC worm motor to move the slider 121 left and right along the slide rail 122 via the synchronous belt, the left limit sensor 129 and the right limit sensor 130 continuously monitor the position of the slider 121. Once the slider 121 moves to the limit area at the left or right end of the slide rail 122, the corresponding limit sensor will trigger a signal and transmit it to the sub-control module 108. After receiving the signal, the sub-control module 108 immediately controls the drive motor 120 to stop, thus avoiding problems such as the slider 121 colliding with the end of the slide rail 122, the synchronous belt falling off, or the barcode scanning device being damaged due to overtravel.

[0051] The precise positioning functions of the limit position sensor and the storage position sensor provided in this solution complement each other, ensuring the smooth movement of slider 121 within its effective stroke and providing solid protection for the safe operation of the barcode scanning device. This ensures the stability and reliability of the mobile scanning system throughout the entire process of asset 200 entry, exit, and inventory.

[0052] In one specific implementation, the cables integrated within the drag chain 123 include at least a power line, a data line, a signal line, and a motor control line connected to the sub-control module 108, wherein the power line is used to power the barcode scanning device; the data line is used to transmit the scanning data of the barcode scanning device; the signal line is used to transmit the detection signals of the storage positioning sensor 126 and the extreme position sensor; and the motor control line is used to transmit control signals to the drive motor 120.

[0053] In this application, the cable chain 123 integrates various functional cables in a well-organized layout, including at least power cables, data cables, signal cables, and motor control cables. The power cable is dedicated to powering the barcode scanner, ensuring the continuous and stable operation of various electronic components. The data cable primarily transmits the asset 200 barcode data obtained by the barcode scanner, feeding this crucial information back to the sub-control module 108 in real time, providing data support for the binding and verification of asset 200 information and storage location signals. The signal cable transmits the detection signals from the storage location sensor 126 and the extreme position sensor. The motor control cable specifically transmits control signals from the sub-control module 108 to the DC worm gear drive motor 120, including commands for motor start, stop, forward / reverse rotation, and speed adjustment, ensuring the motor can accurately drive the slider 121 to reciprocate along the slide rail 122, cooperating with the barcode scanner to complete operations such as warehouse entry barcode scanning and inventory scanning. These cables perform their respective functions and work together to build an efficient transmission channel between the sub-control module 108 and the various execution components of the mobile scanning system, laying a solid hardware foundation for the accurate operation of the entire system.

[0054] like Figure 4 As shown, in a specific embodiment, the slide rail mechanism 122 is provided with a storage position sensing bar 131, and the storage position sensing bar 131 is provided with a plurality of mechanical positioning structures for marking the storage position along its length direction; the slider 121 is equipped with a storage position positioning sensor 126 that cooperates with the mechanical positioning structure, and the storage position positioning sensor 126 is used to detect the mechanical positioning structure during movement and generate an electrical signal that marks the center of a specific storage position; the storage position positioning sensor 126 is electrically connected to the sub-control module 108.

[0055] In this application, a storage level sensing baffle 131 is fixedly installed on the slide rail mechanism 122. To achieve precise positioning of the storage level, the storage level sensing baffle 131 is precisely aligned with the storage level layout of the storage layer 103 along the length of the slide rail 122, and has multiple evenly distributed mechanical positioning structures processed along its own length. In this solution, the mechanical positioning structure is specifically manifested as storage level sensing notches 132. It is worth noting that the number of storage level sensing notches 132 strictly matches the number of storage levels in the corresponding storage layer 103. For example, the layer where single-phase energy meters and current transformers are located has 9 storage levels, so 9 storage level sensing notches 132 are set accordingly. The layer where three-phase energy meters, concentrators, and metering terminals are located has 6 storage levels, so 6 storage level sensing notches 132 are set accordingly. Each notch precisely marks the center position of a storage level, thereby forming an intuitive and stable mechanical positioning reference.

[0056] In this solution, the storage location sensor 126 used in conjunction with the mechanical positioning structure is specifically an infrared sensor 116, which is integrated and installed on the slider 121. Its detection direction precisely corresponds to the notch position of the storage location sensing bar. Driven by the slider 121, it can move smoothly along the slide rail 122 with the scanning device, laying the foundation for subsequent storage location positioning and scanning operations.

[0057] In use, the slider 121 drives the infrared sensor 116 to continuously detect the status of the barrier. When it slides to the notch corresponding to a storage location, the infrared detection signal of the sensor will change significantly, thereby generating an electrical signal that identifies the center position of the specific storage location, achieving precise positioning of the storage location. The infrared sensor 116 establishes a stable electrical connection with the sub-control module 108 of this layer through the signal line in the drag chain 123, transmitting the generated positioning electrical signal to the sub-control module 108 in real time, providing the sub-control module 108 with accurate position feedback. After receiving the signal, the sub-control module 108 can determine that the slider 121 has reached the target storage location, and then controls the drive motor 120 to stop, ensuring that the barcode scanning device is exactly above the center of the storage location. This provides a reliable position guarantee for the accurate scanning of the subsequent asset 200 barcodes, effectively supporting the accurate identification and information collection of each storage location asset 200 in processes such as warehousing and inventory.

[0058] In some implementations, this application provides a method for managing power assets 200 based on the above-mentioned metering system of the slide rail 122 type shelf 100 applied to the terminal warehouse of the power system. The warehousing method includes the following steps: in response to the asset 200 being placed in the target storage location, the sensing module 112 of the storage location is triggered; the sub-control module 108 of the layer where the storage location is located receives the trigger signal and controls the barcode scanning device to move above the target storage location to perform barcode scanning; the sub-control module 108 binds the successfully scanned asset 200 barcode information with the identification information and sensing signal of the target storage location to form an warehousing record; the sub-control module 108 or the main control module 109 controls the display module 119 of the target storage location to display the successful warehousing status and uploads the warehousing record.

[0059] In this application, the warehousing process in the power asset management method is based on the hardware architecture of the sliding rail rack metering system to achieve precise control of the entire process. The specific steps and technical logic are as follows: When the staff manually places the power metering assets 200, such as single-phase energy meters and transformers, into the target storage location, the asset 200 will press down the infrared pressure plate 113 (i.e., the sensing module) corresponding to the storage location, causing the moving block 114 of the infrared pressure plate 113 to move downward, triggering the infrared sensor 116 to generate a sensing signal, thus completing the warehousing trigger action. This trigger signal will be collected through the wiring in the upright 105 of the rack 100 to the sub-control module 108 of the layer where the target storage location is located. After receiving the signal, the sub-control module 108 immediately starts the barcode scanning control process, that is, drives the DC worm gear motor of the upper layer to rotate, and drives the slider 121 and the scanning terminal 124 installed on the slider 121 to move from the origin along the slide rail 122 through the synchronous belt in the slide rail 122. During the movement, the storage location sensor 126 on the slider 121 detects the storage location sensing notch 132 on the storage location sensing barrier corresponding to the target storage location. When the signal changes, it is determined that the target storage location has been reached. The sub-control module 108 then controls the motor to stop, and the scanning dock 124 starts scanning the asset 200 barcode. If the scan is successful, the sub-control module 108 binds and verifies the acquired asset 200 barcode information with the identification information of the target storage location and the sensing signal of the infrared pressure plate 113 to ensure that the asset 200 and the storage location correspond accurately, forming a complete entry record. After the verification is passed, the sub-control module 108 and the main control module 109 drive the display module 119 of the target storage location to light up a green light through hierarchical control, intuitively reflecting the successful entry status. At the same time, the sub-control module 108 uploads the entry record to the main control module 109, and then the main control module 109 synchronizes it to the host computer through the communication module in the top cover 101, completing the entire entry process and realizing the visualization and traceability management of the asset 200 entry.

[0060] In a specific implementation, the outbound method includes the following steps: the main control module 109 receives an outbound instruction from the host computer, the instruction containing information about the target asset 200; the main control module 109 determines the shelf 100, layer, and storage location of the asset 200 based on the asset information; the main control module 109 triggers the global indicator light of the target shelf 100 and sends a guidance instruction to the sub-control module 108 of the layer where the target storage location is located; the sub-control module 108 drives the display module 119 of the target storage location to light up in a preset guidance mode according to the guidance instruction to provide visual guidance for picking up the goods; in response to the asset 200 being taken away causing a change in the state of the sensing module 112, the sub-control module 108 confirms that the outbound process is complete and updates the status.

[0061] In this application, the specific steps and technical logic of the power asset release method are as follows: The main control module 109, as the core of the machine's communication and scheduling, first receives the outbound instruction from the host computer through the communication module inside the top cover 101. This instruction contains detailed information about the target asset 200 to be outbound. This information, along with the storage location identifier bound at the time of entry, is stored in the system. The main control module 109 can quickly match and query the asset 200 information to accurately determine the shelf 100, the corresponding storage layer 103, and the specific storage location of the target asset 200.

[0062] After positioning is completed, the main control module 109 simultaneously executes dual guidance actions: on the one hand, it triggers the shelf indicator light 102 of the target shelf 100 to light up, providing visual guidance for workers to quickly locate and operate the shelf 100 in a scenario where multiple shelves 100 are connected in parallel. On the other hand, it sends a precise guidance command to the sub-control module 108 of the layer where the target storage location is located through the parallel lines in the side column 105 of the shelf 100. After receiving the command, the sub-control module 108 immediately drives the display module 119 of the target storage location to light up in a preset guidance mode. Combined with the system status indication rules, the storage location label will light up a preset color (such as green or yellow) light at this time to avoid manual error.

[0063] Guided by both the shelf indicator light 102 and the storage location label, staff manually retrieve the electricity metering asset 200 from the target storage location. Once asset 200 is removed, the infrared pressure plate 113 of that storage location loses its downward pressure, causing the internal rear counterweight 115 to lift the moving block 114, resulting in a change in the signal from the infrared sensor 116. This status change signal is transmitted in real-time to the sub-control module 108 of this layer. The sub-control module 108, by recognizing this signal change, confirms that the target asset 200 has been successfully retrieved, then updates the outbound status (e.g., unbinding the asset from the storage location), and uploads the outbound completion information to the main control module 109. The main control module 109 then synchronously feeds back to the host computer, achieving closed-loop control of the outbound process and ensuring the accuracy and traceability of the asset 200 outbound operation.

[0064] In a specific implementation plan, the inventory method for power assets 200 includes the following steps: the main control module 109 receives the inventory instruction issued by the host computer and synchronously sends an inventory start signal to the sub-control modules 108 of all layers; each sub-control module 108 controls the barcode scanning device of its layer to move to each storage location of its layer in a preset order for barcode scanning; for each storage location, the sub-control module 108 compares and verifies the barcode scanning result with the current status of the sensing module 112 of that storage location; each sub-control module 108 uploads the verified inventory data to the main control module 109, which then summarizes and generates a complete list of shelf assets 200.

[0065] The specific steps and technical principles of the power asset inventory method in this application are as follows: As the core of the whole machine management, the main control module 109 first receives the inventory command issued by the host computer. After the command is transmitted through the communication module in the top cover 101, the main control module 109 immediately sends the inventory start signal to the sub-control modules 108 of all shelves 103 through the parallel lines in the column 105, ensuring that the inventory tasks of each shelf start in a coordinated manner, realizing the efficient mode of simultaneous inventory of the entire shelf 100.

[0066] Upon receiving the start signal, each sub-control module 108 quickly activates the moving scanning system for its respective floor: driving the DC worm gear motor to rotate, which in turn drives the slider 121 and the upper scanning dock 124 from the origin via the synchronous belt within the slide rail 122, scanning all storage locations in the floor sequentially according to a preset order. During the movement, the storage location positioning sensor 126 on the slider 121 detects the corresponding notch on the storage location sensing bar in real time. When the signal changes, it is determined that the scanning dock 124 has reached above the center of the target storage location, and the sub-control module 108 immediately controls the motor to stop, while the scanning dock 124 starts barcode scanning. After scanning is completed, the motor drives the slider 121 to move to the next storage location again, repeating the above positioning and scanning process until all storage locations in the floor have been scanned.

[0067] For each storage location, the sub-control module 108 performs precise comparison and verification. The core of this process is to correlate and verify the asset 200 barcode information obtained from the current scan (if the scan is successful, the corresponding information is obtained; if not scanned, no relevant data is available) with the current status of the sensing module 112 (i.e., the infrared pressure plate signal) for that storage location. The specific verification logic is clear: if the infrared pressure plate 113 detects a sensing signal (indicating the presence of an asset in the storage location) and the scan successfully obtains the asset 200 barcode information, then asset 200 is determined to be present and the information matches; if the infrared pressure plate 113 has a sensing signal (indicating the presence of an asset in the storage location) but multiple scans still fail to obtain barcode information, then asset 200 is determined to be present but the information is abnormal; if the infrared pressure plate 113 has no sensing signal and the storage location has no asset 200, but the system contains a historical scan record for that storage location (i.e., the asset was previously stored and bound), then asset 200 is determined to be missing and abnormal.

[0068] After each sub-control module 108 completes the scanning and verification of all storage locations on its respective floor, it uploads complete inventory data, including storage location identifiers, scanning results, sensor status, and verification conclusions, to the main control module 109 via the lines within the column 105. The main control module 109 receives the inventory data from all sub-control modules 108, performs global aggregation and integration, removes duplicate information, marks abnormal storage locations, and ultimately generates a complete asset list 200 covering all floors and storage locations of the shelving unit 100. This list is then synchronously fed back to the host computer, enabling visualized and traceable management of the asset 200 inventory and ensuring consistency between the physical inventory and the accounting records.

[0069] In one specific implementation, when the scanning device fails to scan the target storage location for the first time, the sub-control module 108 controls the scanning device to perform a preset number of retry scans; the retry scan includes controlling the scanning device to alternately shift its position in a first direction and then in the opposite second direction before scanning again; if it still fails after reaching the maximum number of retry attempts, the storage location is marked as abnormal and reported.

[0070] In the scheme of this application, when the barcode scanning device fails to scan the target storage location on the first attempt during warehousing or inventory, the sub-control module 108 will immediately activate a preset fault retry scanning mechanism. This mechanism is based on the motion control logic of the slide rail 122 and the hardware co-design to ensure that the scanning success rate is maximized. Specifically, the sub-control module 108 sends a control signal to the DC worm gear motor through the motor control line, driving the motor 120 to move the slider 121 and the scanning dock 124 to shift a preset distance (e.g., 10mm) in the first direction relative to the origin. After reaching the new position, scanning is restarted. If this scan is still unsuccessful, the sub-control module 108 controls the motor to move the scanning dock 124 to shift a preset distance (e.g., 10mm) in the opposite second direction for a third scan. If the scan is successful, scanning stops; if unsuccessful, the above alternating position shift scanning mode is repeated until a preset number of cycles (e.g., five times) are completed. If the barcode scanning device still fails to recognize the asset barcode after the preset number of cycles, the sub-control module 108 will determine that the storage location is in an abnormal state. On one hand, it drives the display module 119 of the storage location to light up a red fault light, intuitively indicating a scanning failure. On the other hand, it uploads abnormal information such as storage location identification and scanning failure to the main control module 109 through the lines inside the column 105, and then the main control module 109 synchronously feeds back to the host computer, realizing timely reporting and visual warning of abnormal status, and ensuring the rigor of asset management.

[0071] In one specific implementation, a physical mark 134 is respectively provided on the outer side of the mechanical positioning structure at both ends of the slide rail mechanism 122; the origin calibration method includes the following steps: the sub-control module 108 controls the drive motor 120 to drive the slider 121 to move along the first direction and the second direction respectively; when the slider 121 detects a physical mark 134 set on the slide rail 122 for the first time during the movement along the first direction, the first position information is recorded; the slider 121 is controlled to move along the second direction until another physical mark 134 is detected, and the second position information is recorded; the position determined based on the second position information is set as the coordinate origin of the scanning device movement; after the origin calibration is completed, the sub-control module 108 calculates the driving amount required to control the scanning device to move to any target storage location based on this coordinate origin and the known spacing between each storage location.

[0072] like Figure 3-1As shown in the present application, the slide rail mechanism 122 has multiple mechanical positioning structures. A physical mark 134 is provided on the outer side of the leftmost mechanical positioning structure, and another physical mark 134 is provided on the outer side of the rightmost mechanical positioning structure. The origin calibration method uses the two physical marks 134 on the slide rail 122 (which can be a storage sensing notch or other form of notch) as a reference. The core of the method is to accurately lock the origin position by the reciprocating left and right movement of the slider 121, providing a reliable coordinate reference for the accurate positioning of the barcode scanning device. The specific process and technical advantages are as follows: The execution of this method is led by the sub-control module 108. First, the sub-control module 108 sends a control signal to the DC worm gear drive motor 120. The motor drives the slider 121 and the infrared sensor 116 on the slider 121 to move along the first direction (as shown on the right) via the synchronous belt in the slide rail 122. During the movement, the sensor detects the physical markers 134 on the slide rail 122 in real time. When a physical marker 134 is detected for the first time, the sub-control module 108 immediately records the first position information at this moment, completing the initial positioning. Subsequently, the sub-control module 108 controls the motor in the opposite direction, driving the slider 121 to move along the opposite second direction (as shown on the left) until the sensor detects another physical marker 134. At this time, the second position information is recorded, and this position is officially set as the coordinate origin of the scanning device's movement.

[0073] After the origin calibration is completed, the sub-control module 108 can rely on the coordinate origin and combine the precise spacing parameters of each storage location pre-stored by the system to calculate the number of pulses or movement time of the DC worm motor, and accurately determine the driving amount required to drive the scanning device to any target storage location, thereby realizing the precise positioning of asset 200 and automated scanning, inventory and other operations.

[0074] The origin determination method in this solution effectively avoids positioning deviations caused by factors such as sensor errors and mechanical gaps that may occur during unidirectional movement through bidirectional movement verification logic. This significantly improves the reliability and repeatability of the system, laying a solid foundation for precise control of the entire process of power asset warehousing, outbound, and inventory.

[0075] It is worth noting that, to ensure the uniformity and reliability of the origin calibration method, this scheme adopts a fixed motion sequence during calibration: first, the slider is controlled to move along the first direction, and then it moves along the second direction. Through this standardized bidirectional motion process, different initial positions can be effectively adapted to and unidirectional cumulative errors can be eliminated, thereby ensuring the consistency and accuracy of each origin positioning process.

[0076] In one specific implementation, the physical marker 134 has a first distance from the nearest mechanical positioning structure, and there is a second distance between two adjacent mechanical positioning structures, and the first distance and the second distance are different; the detection of the physical marker 134 is based on the difference in signal time characteristics generated when the sensor detects the mechanical positioning structure and the physical marker 134 during the movement.

[0077] In this application, the physical marker 134 has a first distance from the nearest mechanical positioning structure, and two adjacent mechanical positioning structures have a second distance. The first distance and the second distance are not equal, and the first distance is less than the second distance. Based on this, when the sensor moves, it will generate distinguishable signal time characteristic differences when passing the physical marker 134 and the mechanical positioning structure due to the different spacing, thereby realizing the detection and identification of the physical marker 134.

[0078] In one specific implementation, when the positioning signal of the storage location sensor 126 fails, the drive motor 120 is controlled to move the slider 121 along the slide rail 122; when the slider 121 triggers the limit position sensor located at the end of the travel of the slide rail 122, the drive motor 120 is controlled to stop; the slider 121 is controlled to move from the position where the limit position sensor is triggered towards the center of the slide rail 122; during the movement of the slider 121 in the center direction, the storage location sensor 126 on the slider 121 detects two physical marks 134 on the slide rail mechanism 122; when the sensor detects two physical marks 134 in sequence, the position of the detected second physical mark 134 is taken as the origin of the coordinate system.

[0079] In the scheme of this application, when the positioning signal of the storage location sensor 126 fails, the system initiates the origin reset process to restore the accurate positioning capability by relying on the limit position sensor of the slide rail mechanism 122 and the physical marker 134. The specific operation logic and technical principle are as follows: When the sub-control module 108 detects that the storage positioning sensor 126 cannot output a positioning signal normally, it immediately activates the emergency origin calibration mechanism. First, it sends a control signal to the DC worm gear drive motor 120 via the motor control line. The drive motor 120 rotates and drives the slider 121 to move along the slide rail 122 via the synchronous belt inside the slide rail 122 (the direction can be preset to approach any end of the stroke). When the slider 121 moves to the end of the stroke of the slide rail 122, it triggers the limit position sensor set at this location. The sensor then sends a trigger signal to the sub-control module 108. Upon receiving the signal, the sub-control module 108 immediately controls the drive motor 120 to stop, thereby determining a clear stroke boundary reference and preventing the slider 121 from being damaged by overtravel.

[0080] Subsequently, the sub-control module 108 reverses the control of the drive motor 120, causing the slider 121 to move smoothly from the boundary position of the trigger limit position sensor towards the center of the slide rail 122. During the movement, the storage position sensor 126 on the slider 121 remains in a detection state, used to identify the two physical marks 134 on the slide rail mechanism 122. In this scheme, these two physical marks 134 are specific notches on the storage sensing stop bar. When the sensor detects these two physical marks 134 in sequence, the sub-control module 108 records the position information corresponding to the second physical mark 134 and officially sets this position as the coordinate origin of the scanning device's movement, ensuring that the reset origin is consistent with the reference during normal system operation.

[0081] It is worth noting that, to ensure the uniformity and reliability of the origin calibration method, this scheme, when the positioning signal of the storage location sensor fails, controls the drive motor to move the slider along the slide rail in a fixed sequence: first, the slider moves along the second direction to the limit position sensor, and then moves along the first direction. This standardized bidirectional motion process effectively adapts to different initial positions and eliminates unidirectional cumulative errors, thereby ensuring the consistency and accuracy of each origin calibration process.

[0082] The origin reset method provided in this solution relies on the existing hardware structure of the system and requires no additional components. It can quickly restore the origin reference when the storage location sensor 126 fails. After the reset is completed, the sub-control module 108 can continue to accurately calculate the driving amount for the scanning device to move to any target storage location based on the coordinate origin and the preset storage location distance. This ensures the normal operation of core operations such as inbound scanning and inventory scanning, and effectively improves the fault tolerance and operational stability of the system.

A power asset management method based on claim 7, characterized in that, The outbound process includes the following steps: The main control module (109) receives the outbound instruction issued by the host computer, the instruction containing the target asset (200) information; The main control module (109) determines the shelf (100), layer, and storage location of the asset (200) based on the asset (200) information; The main control module (109) triggers the global indicator light of the target shelf (100) and sends a guidance instruction to the sub-control module (108) of the layer where the target storage location is located; The sub-control module (108) drives the display module (119) of the target storage location to light up in a preset guidance mode according to the guidance instruction, so as to provide visual guidance for picking up goods; In response to the asset (200) being taken away, causing a change in the state of the sensing module (112), the sub-control module (108) confirms that the outbound process is complete and updates the state.

9. The power asset management method according to claim 7, characterized in that, The methods for inventorying power assets include the following steps: The main control module (109) receives the inventory command issued by the host computer and synchronously sends the inventory start signal to the sub-control modules (108) of all layers. Each sub-control module (108) controls the barcode scanning device of its own layer to move to each storage location of its own layer in a preset order to scan the barcode; For each storage location, the sub-control module (108) compares and verifies the scanning result with the current status of the sensing module (112) of that storage location; Each sub-control module (108) uploads the verified inventory data to the main control module (109), which then compiles and generates a complete list of shelf (100) assets (200).

10. The power asset management method according to claim 7, characterized in that, When the scanning device fails to scan the target storage location for the first time, the sub-control module (108) controls the scanning device to perform a preset number of retry scans; The retry scan includes controlling the scanning device to alternately shift its position in a first direction and then in the opposite second direction before scanning again; If the maximum number of retries is reached and the attempt still fails, the storage location will be marked as abnormal and reported.

11. The power asset management method according to claim 7, characterized in that, A physical mark (134) is provided on the outer side of the mechanical positioning structure at both ends of the slide rail mechanism (122); the origin calibration method includes the following steps: The sub-control module (108) controls the drive motor (120) to drive the slider (121) to move along the first direction and the second direction respectively; When the slider (121) detects a physical marker (134) set on the slide rail (122) for the first time during its movement along the first direction, the first position information is recorded; when the slider (121) is controlled to move along the second direction until another physical marker (134) is detected, the second position information is recorded. The position determined based on the second position information is set as the origin of the coordinates for the movement of the scanning device; After the origin calibration is completed, the sub-control module (108) calculates the driving amount required to control the scanning device to move to any target storage location based on this coordinate origin and the known spacing between each storage location.

12. The power asset management method according to claim 11, characterized in that, The physical marker (134) has a first distance from the nearest mechanical positioning structure, and there is a second distance between two adjacent mechanical positioning structures, and the first distance and the second distance are different; The detection of the physical marker (134) is based on the difference in signal time characteristics generated when the sensor detects the mechanical positioning structure and the physical marker (134) during the movement.

13. The power asset management method according to claim 11, characterized in that, When the positioning signal of the storage location sensor (126) fails, the control drive motor (120) drives the slider (121) to move along the slide rail (122); When the slider (121) triggers the limit position sensor located at the end of the travel of the slide rail (122), the drive motor (120) is controlled to stop; Control the slider (121) to move from the position where the limit position sensor is triggered towards the center of the slide rail (122); During the movement of the slider (121) in the central direction, the storage positioning sensor (126) on the slider (121) detects two physical marks (134) on the slide rail mechanism (122). When the sensor detects two physical markers (134) in sequence, the position of the detected second physical marker (134) is taken as the origin of the coordinate system.
