Description

Technical Field

[0001] This invention relates to the field of power material logistics and transportation equipment technology, specifically to a power material distribution device based on radio frequency technology. Background Technology

[0002] Emergency repairs and maintenance of power systems typically need to be carried out outdoors or in the field, involving the transfer and distribution of heavy electrical materials such as transformers, cable reels, and insulators. To improve loading and unloading efficiency, conveyor belts or roller conveyors are widely used in the on-site transfer of electrical materials.

[0003] Existing power material conveying equipment has certain limitations in practical applications. First, conventional conveyors mostly use fixed outriggers or simple mechanical adjustment supports, whose support structures lack adaptability to complex terrain. At field repair sites, the ground is often uneven or the soil is soft, making it difficult for traditional equipment to level quickly, causing the conveyor frame to tilt or sway. This not only increases the time and cost of on-site setup but also can lead to equipment tipping over or materials slipping due to unstable support, affecting operational safety.

[0004] Secondly, during the material unloading process, existing non-powered roller conveyors primarily rely on gravity to propel materials downwards. For heavy electrical equipment, the acceleration effect of gravity is significant on long-distance or steeply inclined conveying paths, causing the materials to slide at increasingly faster speeds. If a stable power supply is lacking on-site, electric braking devices cannot be used, and heavy materials are prone to going out of control and violently colliding with the end baffle or other materials, resulting in equipment damage or personnel injury. Existing mechanical friction braking methods are also prone to unstable braking torque due to wear, making it difficult to ensure the uniform and stable transmission of heavy materials.

[0005] Furthermore, the current power material management model remains relatively traditional, with physical material transfer and information verification often being two separate processes. Workers typically need to manually count materials or use handheld devices to scan tags individually. This method is not only inefficient but also prone to omissions or misrecording. The conveying equipment itself only serves as a physical transport tool and cannot obtain real-time information on material identity and flow during the dynamic process of material movement. This results in a time lag or discrepancy between on-site inventory data and the actual logistics status, making it difficult to meet the requirements of refined material management for power emergency repairs. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a power material distribution device based on radio frequency technology, which solves the problems of traditional conveying equipment requiring high ground flatness and being prone to tilting and instability, heavy materials being prone to impact due to gravity acceleration in the absence of power, and the low efficiency and poor data accuracy of manual inventory management.

[0009] Preferably, the two ends of the connecting rod are respectively connected to the piston rod end of the hydraulic rod and the side wall of the connecting platform, and the hydraulic rod extends and retracts in a straight line to drive the connecting rod to swing.

[0010] Preferably, the radio frequency sensors are arranged in a symmetrical array at the feed end and the discharge end, and the support rods are arranged in a parallel array on both sides of the telescopic conveyor mechanism.

[0011] Preferably, the material transport assembly includes a transport mechanism and multiple passive magnetic eddy current descent units. The transport mechanism includes multiple connecting shafts, multiple cross-hinged telescopic plates, and multiple transport cylinders. Both ends of each connecting shaft are rotatably connected between the telescopic plates. Several telescopic plates are fixedly connected to support rods on one side. A support shaft is fixedly connected between the bottom ends of every two telescopic plates. Both ends of each transport cylinder are rotatably connected between the telescopic plates.

[0012] Preferably, each of the passive magnetic eddy current descent units includes two rotating shafts, a conductive cylinder, and a permanent magnet. The outer wall of the conductive cylinder is fixedly connected to the inner wall of the transport cylinder, and the two ends of the permanent magnet are fixedly connected between the rotating shafts. The conductive cylinder is sleeved on the outside of the permanent magnet, and an air gap is provided between the two. The conductive cylinder rotates with the transport cylinder relative to the permanent magnet, cutting magnetic field lines.

[0013] Preferably, the conductive cylinder is made of copper or aluminum, the outer wall of the conductive cylinder is attached to the inner wall of the transport cylinder, and the permanent magnet is an array of magnets arranged along the axial direction.

[0014] Preferably, the air gap is formed between the inner circumferential surface of the conductive cylinder and the outer circumferential surface of the permanent magnet, and the conductive cylinder and the permanent magnet do not contact each other.

[0015] Preferably, the air gap is formed between the inner circumferential surface of the conductive cylinder and the outer circumferential surface of the permanent magnet, and the conductive cylinder and the permanent magnet do not contact each other.

[0016] Preferably, the power material distribution management system based on radio frequency technology specifically includes: The adaptive balance control subsystem is connected to the pressure sensor and the oil pump respectively. It is configured to receive the support force signal fed back by the pressure sensor. When uneven force is detected, it generates a control command to drive the oil pump to work.

[0017] This invention provides a power material distribution device based on radio frequency technology. It has the following beneficial effects: 1. This invention achieves adaptive and stable support for complex terrain by incorporating pressure sensors, oil pumps, and hydraulic rod adjustment circuits into the support components. When the device is deployed at uneven or muddy repair sites, the pressure sensors can monitor the stress state of the support legs in real time. By controlling the oil pump to drive the hydraulic rod to extend and retract, the connecting rod and connecting platform can finely adjust the height and angle of the support shaft. This solves the problems of traditional conveying equipment requiring high ground flatness and being prone to tilting and instability in the field, ensuring the structural stability and operational safety of power materials during delivery.

[0018] 2. This invention achieves constant-speed safe transport of heavy materials in environments without power supply by integrating a conductive cylinder and a permanent magnet into a magnetic eddy current slow-descent unit inside the transport cylinder. Utilizing the principle of electromagnetic induction, when heavy materials drive the drum to rotate, the conductive cylinder cuts the magnetic field lines to generate a reverse braking torque, and the torque automatically increases with the rotation speed. This allows the device to prevent the impact risk of heavy transformers, cables, and other materials due to gravity-induced acceleration downhill without external power drive, thus protecting the safety of materials and equipment. It is particularly suitable for power emergency repair sites lacking power supply.

[0019] 3. This invention deeply integrates radio frequency identification (RFID) technology with mechanical conveying structures. By embedding RFID sensors at key nodes and cooperating with vehicle-mounted data terminals and management cloud platforms, it achieves digital closed-loop management of the material loading and unloading process. Thanks to the stable physical path provided by hydraulic support and the stable transmission speed provided by magnetic eddy current descent, the RFID sensors can obtain an ideal tag reading environment, thereby collecting the physical ID of the materials and determining their flow direction. This not only replaces the inefficient manual counting and post-event recording mode, but also ensures the real-time accuracy of on-site inventory data, achieving consistent management of accounts, cards, and materials.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See attached document Figure 1 -Appendix Figure 4Multiple support rods 1, with a fixed rod 2 fixedly connected between each pair of support rods 1, an adaptive support component inside the support rod 1, radio frequency sensors 11 fixedly connected to the top of several support rods 1, a fixed shaft 12 fixedly connected between the support rods 1, a telescopic conveying mechanism between the support rods 1, and a controller electrically connected to the radio frequency sensors 11. The controller has a built-in power material distribution management system based on radio frequency technology. The adaptive support assembly includes a pressure sensor 8, an oil pump 4, a hydraulic rod 6, a connecting rod 7, and a connecting platform 9. The outer wall of the pressure sensor 8 is fixedly connected to the top of the connecting platform 9. The controller is electrically connected to the pressure sensor 8 and the oil pump 4. The output end of the oil pump 4 is connected to the hydraulic rod 6. The telescopic end of the hydraulic rod 6 is connected to the connecting platform 9 through the connecting rod 7. A movable wheel 10 is fixedly connected to the bottom of the connecting platform 9. The adaptive support assembly also includes an oil storage tank 3 and an oil guide pipe 5. The oil storage tank 3 is provided with an oil inlet 21. The input end of the oil pump 4 is connected to the oil storage tank 3, and the output end is connected to the oil inlet of the hydraulic rod 6 through the oil guide pipe 5. The two ends of the connecting rod 7 are respectively connected to the piston rod end of the hydraulic rod 6 and the side wall of the connecting platform 9. The hydraulic rod 6 extends and retracts in a straight line to drive the connecting rod 7 to swing. The radio frequency sensors 11 are arranged in a symmetrical array at the feed end and the discharge end. The support rods 1 are arranged in a parallel array on both sides of the telescopic conveying mechanism.

[0024] Specifically, the system first utilizes a scissor-type linkage mechanism constructed by the telescopic plate 14, fixed shaft 12, and connecting shaft 13 to achieve flexible deployment, and is laid to the designated work position under the guidance of the bottom moving wheels 10. When the equipment touches the ground with complex terrain, the pressure sensor 8 is activated to monitor and capture the force balance state of the support rod 1 and the fixed rod 2 in real time. Once uneven force is detected, the system immediately generates a feedback command, and the intelligent control oil pump 4 responds quickly, delivering the hydraulic oil stored in the oil tank 3 to the hydraulic rod 6 through the oil guide pipe 5. With the extension and retraction of the hydraulic rod 6, the resulting linear thrust is converted into the fine-tuning action of the connecting platform 9 through the connecting rod 7, thereby locking the height and correcting the attitude of the support shaft 15. In addition, the design of the oil inlet 21 provides a guarantee for the long-term operation of the system, enabling the device to achieve adaptive support even in uneven and harsh environments such as power repair sites, laying a solid foundation for the safety of subsequent material transmission.

[0025] See attached document Figure 5 and attached Figure 6The material transport component includes a transport mechanism and multiple passive magnetic eddy current descent units. The transport mechanism includes multiple connecting shafts 13, multiple cross-hinged telescopic plates 14, and multiple transport cylinders 16. Both ends of each connecting shaft 13 are rotatably connected between the telescopic plates 14. Several telescopic plates 14 are fixedly connected to the support rods 1 on one side. A support shaft 15 is fixedly connected between the bottom ends of every two telescopic plates 14. Both ends of each transport cylinder 16 are rotatably connected between the telescopic plates 14. Each passive eddy current descent unit includes two rotating shafts 17, a conductive cylinder 18, and a permanent magnet 19. The outer wall of the conductive cylinder 18 is fixedly connected to the inner wall of the transport cylinder 16. The two ends of the permanent magnet 19 are fixedly connected between the rotating shafts 17. The conductive cylinder 18 is sleeved on the outside of the permanent magnet 19 and an air gap 20 is provided between them. The conductive cylinder 18 rotates with the transport cylinder 16 relative to the permanent magnet 19 to cut magnetic field lines. The conductive cylinder 18 is made of copper or aluminum. The outer wall of the conductive cylinder 18 is attached to the inner wall of the transport cylinder 16. The permanent magnet 19 is an array of magnets arranged along the axial direction. An air gap 20 is formed between the inner circumferential surface of the conductive cylinder 18 and the outer circumferential surface of the permanent magnet 19. The conductive cylinder 18 and the permanent magnet 19 do not contact each other.

[0026] Specifically, when the electrical materials slide down the conveyor channel under the pull of gravity, the enormous gravitational potential energy is converted into mechanical kinetic energy through the friction of the contact surface, driving the conveyor cylinder 16 to rotate around the rotating shaft 17. This rotational motion is transmitted to the internally fitted conductive cylinder 18, causing it to enter a synchronous operation state. At this time, although there is an air gap 20 between the rotating conductive cylinder 18 and the stationary permanent magnet 19, a magnetic field interaction space is constructed. The high-speed rotating conductive cylinder 18 continuously cuts the high-intensity magnetic field lines released by the permanent magnet 19, generating induced eddy currents inside the conductor. This eddy current is converted into a reverse braking resistance torque, applying flexible braking to the rotating conductive cylinder 18. The faster the materials slide down, the more violently they cut the magnetic field lines, and the stronger the braking resistance becomes. This ensures that no matter the weight of the electrical materials, the risk of runaway collisions can be completely eliminated, and they can always pass through the conveyor channel calmly and gracefully at a uniform speed.

[0027] The power material distribution management system based on radio frequency technology specifically includes: The adaptive balance control subsystem is connected to the pressure sensor 8 and the oil pump 4 respectively. It is configured to receive the support force signal fed back by the pressure sensor 8. When uneven force is detected, it generates a control command to drive the oil pump 4 to work. The device achieves stable support in complex terrain through the automatic adjustment of the hydraulic rod 6. The material flow management subsystem is connected to the radio frequency sensor 11 and is configured to receive the material physical ID read by the radio frequency sensor 11, automatically generate entry and exit records in combination with material flow data, and upload them to the cloud platform for accounting verification, so as to realize the attitude stability control and digital management collaboration during the loading and unloading of materials.

[0028] Specifically, the present invention provides a power material distribution management system based on radio frequency technology, which operates in a controller electrically connected to a telescopic conveyor mechanism.

[0029] The system includes: a controller, radio frequency sensors 11 installed on the conveying path, an on-board data terminal, and a remote material management cloud platform.

[0030] At the hardware implementation level, the controller specifically includes a microprocessor or programmable logic controller, a data storage unit, a power management module, and an I / O interface circuit. The material flow management subsystem and the adaptive balance control subsystem 101 are computer program codes stored in the data storage unit and executed by the microprocessor. The I / O interface circuit is physically connected to the communication port of the radio frequency sensor 11, the drive circuit of the oil pump 4, and the signal output terminal of the pressure sensor 8, respectively, to realize data acquisition and command issuance.

[0031] The controller's internal logic is divided into an adaptive balance control subsystem and a material flow management subsystem.

[0032] The radio frequency (RF) sensor 11 is positioned on the side of the telescopic conveyor frame or below the gap between adjacent transport cylinders 16. The RF sensor 11 communicates with the controller via wired or wireless means. During material transport, the RF sensor 11 emits RF signals, covering the sensing area above the transport cylinder 16.

[0033] When materials with electronic tags move into the sensing area along with the transport tube 16, the electronic tags are activated and return the stored material ID information. The radio frequency sensor 11 captures this feedback signal, demodulates it, and transmits the digitized material ID to the controller.

[0034] The materials circulation management subsystem is a logic processing unit running within the controller. It receives material physical ID data uploaded by the radio frequency sensor 11. Simultaneously, the subsystem records the timestamp information of the ID being read.

[0035] The material flow management subsystem is configured with flow direction determination logic. Specifically, the flow direction determination logic executed by the material flow management subsystem is configured as follows: real-time sampling of the received signal strength indicator (RSSI) fed back by the radio frequency sensor 11; when the RSSI value shows a low-high-low bell-shaped curve change and the peak value exceeds a preset threshold, it is determined as a valid material passage event. At this time, the logic module synchronously reads the current motor drive command status (forward or reverse rotation) of the telescopic conveyor or reads the operation mode flag (inbound or outbound mode) locked by the user on the onboard data terminal; it associates the detected valid passage event with the current direction status to generate inbound / outbound records with clear flow direction attributes.

[0036] After completing ID reading and flow determination, the material flow management subsystem generates structured record data containing material ID, operation time, operation location, and flow direction.

[0037] The vehicle-mounted data terminal connects to the controller to display the current operational status and statistical data. The terminal also has a built-in wireless communication module that encrypts and transmits the structured record data generated by the materials flow management subsystem to the materials management cloud platform.

[0038] The materials management cloud platform receives data uploaded from the field. The platform's database stores pre-set order information and inventory status. The platform compares the received physical item IDs with the pre-set orders. If a match is found, the platform automatically updates the corresponding materials' inventory status and circulation records, completing the electronic posting.

[0039] The adaptive balance control subsystem is connected to pressure sensor 8 and oil pump 4. While the radio frequency identification (RFID) operation is underway, the adaptive balance control subsystem continuously acquires values ​​from pressure sensor 8.

[0040] When the data from pressure sensor 8 indicates that the support rod 1 and the fixed rod 2 are subjected to uneven forces, the adaptive balance control subsystem outputs a drive signal to the oil pump 4. Based on the drive signal, the oil pump 4 injects or withdraws the medium from the oil reservoir 3 into or from the hydraulic rod 6, driving the connecting platform 9 to adjust its angle.

[0041] This mechanical adjustment process establishes a relatively stable physical positional relationship between the RF sensor 11 and the material tag. The stable transmission posture reduces tag misreading caused by vibration or tilt, ensuring the integrity of data acquired by the material flow management subsystem.

[0042] Specifically, the adaptive balance control subsystem uses hydraulic adjustment to maintain the RF sensor 11 and the material tag above the transport cylinder 16 within the optimal reading distance range specified in the design (e.g., 5cm to 30cm), and keeps the polarization plane of the RF antenna relatively parallel to the tag plane. This physical attitude correction effectively suppresses the tag's deviation from the antenna's main lobe region due to terrain tilt, and also avoids signal multipath interference caused by severe vibration, thus ensuring a high success rate for reading the physical ID of the materials at the physical link level.

[0043] Working principle: In the use of the power material distribution device based on radio frequency technology, the device can be flexibly deployed through the scissor mechanism composed of telescopic plate 14, fixed shaft 12 and connecting shaft 13, and is guided by the moving wheel 10. When the device is deployed and in contact with the ground, the pressure sensor 8 monitors the force balance state of the support rod 1 and the fixed rod 2 in real time, and controls the oil pump 4 to deliver the hydraulic oil in the oil storage tank 3 to the hydraulic rod 6 through the oil guide pipe 5. The telescopic movement of the hydraulic rod 6 pushes the connecting rod 7 and the connecting platform 9 to make fine adjustments, lock the height of the support shaft 15, and ensure system maintenance through the oil injection port 21, thereby achieving adaptive and stable support of the device in uneven emergency repair sites. As the materials slide down, the transport cylinder 16 rotates around the rotating shaft 17 due to gravity friction, which in turn drives the internal conductive cylinder 18 to rotate synchronously at high speed. Since there is an air gap 20 between the conductive cylinder 18 and the central stationary permanent magnet 19, the rotating conductive cylinder 18 cuts the magnetic field lines to generate induced eddy currents, generating a reverse braking torque. This torque automatically increases with the increase of rotation speed, realizing adaptive damping control in a power-free environment, ensuring that heavy materials pass through safely and at a constant speed. As the materials smoothly pass through the conveyor channel using the aforementioned mechanical structure, the radio frequency sensor 11 installed at key nodes is activated. Thanks to the structural stability provided by the hydraulic support and the speed stability provided by the magnetic eddy current, the radio frequency sensor 11 can perform high-precision contactless reading and decoding of the material tags that have slid by, converting the physical ID of the materials into electronic data in real time and recording the flow direction, thus realizing automatic accounting and digital management of power materials during loading and unloading.
