Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent operation and maintenance of power facilities, and in particular to an intelligent electronic pole number plate of a high-voltage distribution line and an operation and maintenance management system thereof. BACKGROUND

[0002] In the operation and maintenance management of a high-voltage distribution line, a pole number plate is a basic facility for identifying key information such as line name, tower number and voltage level. The traditional pole number plate mainly adopts a hanging type aluminum alloy sign or directly paints information on the surface of the pole body. Once the content is made, it cannot be changed. When the line needs to increase or decrease intermediate towers due to reconstruction or expansion, the tower numbers of the whole line must be reordered and the physical replacement of the sign is necessary. This process has significant defects such as high material and labor cost, high safety risk of electrician climbing operation, and resource waste caused by abandoned signs.

[0003] To overcome the above problems, the prior art proposes an electronic pole number plate scheme using an LED display screen, which realizes remote update of information through digital coding and storage. However, such an electronic pole number plate still has the following deficiencies, which lead to its disconnection with the operation and maintenance business process: first, its display function is disconnected with the operation and maintenance operation instruction, is not deeply integrated with the operation and maintenance business process, cannot dynamically display and warn according to the operation and maintenance operation instruction, and lacks linkage capability with the operation and maintenance business process; second, the display system lacks self-adaptive capability to environmental light, has poor visibility in strong light or dark light conditions, is difficult to effectively display operation and maintenance information at the operation site, and affects operation and maintenance efficiency and safety; third, in outdoor harsh environment, the power supply reliability and communication stability of the equipment are insufficient, which leads to the difficulty of continuous and reliable operation of the above functions in operation and maintenance operation.

Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] This application provides an intelligent electronic pole number plate for high-voltage power distribution lines. Please refer to [link / reference]. Figs. 1-3 It includes: electrical box 1, bracket 2, photovoltaic panel 5, power lithium battery pack 6, intelligent control unit module 7, intelligent micro projector 8, and ambient light sensor;

[0042] The electrical box 1 is equipped with the power lithium battery pack 6, the intelligent control unit module 7 and the intelligent micro projector 8 respectively.

[0043] The power lithium battery pack 6 serves as an energy storage unit, supplying power to each power module of the smart electronic pole number plate;

[0044] The intelligent control unit module 7 serves as the control center for the intelligent electronic pole number plate. Its core is a microprocessor integrating a rectifier module, a charge / discharge management module, a Bluetooth module, and a wireless communication module. It receives work instructions from the intelligent operation and maintenance management cloud platform and controls the intelligent micro-projector 8 to project identification information matching the operation and maintenance business process based on these instructions. For example, when receiving a work instruction for emergency repair of a pole fault, the intelligent micro-projector 8 projects a "Fault Repair" sign, including information such as the fault type and faulty equipment; when receiving a work instruction for changing pole information, the intelligent micro-projector 8 projects an "Information Change" sign, including the new pole number and warning message.

[0045] The Bluetooth module supports the Bluetooth 5.0 protocol for short-range data interaction between the mobile terminal and the intelligent control unit module 7, and can receive device operation commands triggered by maintenance personnel. The wireless communication module is used for bidirectional communication with the intelligent operation and maintenance management cloud platform. It can not only receive operation commands, but also periodically or event-triggeredly upload operation status information, including but not limited to operation duration, operation projection mark, operation status, etc. It also supports a converged communication scheme of 4G / 5G and LoRa. In daily operation, it conducts large-volume data interaction (such as firmware upgrades and video streaming) through the 4G / 5G public network. In emergency situations where the public network signal is poor or interrupted, it can automatically switch to the LoRa network to maintain low-power transmission of critical status information and control commands. It can also form a self-organizing network with other similar intelligent electronic pole signs through wireless mesh technology, relaying data from remote nodes without public network signal coverage to nodes with signal coverage, achieving full network coverage and reducing dependence on operator signals.

[0046] The ambient light sensor can be installed inside the electrical box 1 or integrated with the smart micro projector 8;

[0047] The intelligent micro-projector 8 can be a miniature projection module with a protection level of not less than IP67 and wide operating temperature capability. This intelligent micro-projector 8 receives instructions from the intelligent control unit module 7, projects pole information onto the ground or adjacent surfaces, and automatically adjusts the projection brightness and display theme based on ambient light data collected by an ambient light sensor. The projectable information includes pole numbers, QR codes, warning messages, etc., and the content can be dynamically updated according to preset templates or remote commands. After receiving a work instruction from the intelligent operation and maintenance management cloud platform, the intelligent control unit module 7 combines the current work type (such as "batch update" or "fault repair") and ambient light data to generate a control instruction and sends it to the intelligent micro-projector 8. The intelligent micro-projector 8 then projects identification information matching the work status onto the ground or the area adjacent to the pole according to this instruction.

[0048] Specifically, when a tower malfunctions, the intelligent operation and maintenance management cloud platform issues a "fault repair" command. The intelligent control unit module 7 controls the intelligent micro-projector 8 to project the words "fault repair" along with the fault type and equipment information. The display parameters of the above-mentioned information can be dynamically optimized according to ambient lighting conditions. For example, during the day or in strong light, the intelligent micro-projector 8 increases its brightness to the maximum and projects the "fault repair" text, fault type, and equipment information in a high-contrast, large-font, and simplified format onto low-reflection areas such as the tower's shadow, ensuring readability from a distance. At night or in low light, the intelligent micro-projector 8 reduces its brightness and switches the "fault repair" text, fault type, and equipment information to a soft, dark theme to avoid glare and ensure that the information is clearly legible without being dazzling.

[0049] The smart micro-projector 8 also supports multiple trigger modes. It starts when it receives a valid trigger command (such as remote control command, NFC trigger command, mobile terminal control command, AR application command, etc.) and stays in sleep mode at other times to significantly reduce the power consumption of the smart electronic pole number and extend the battery life of the power lithium battery pack 6.

[0050] One end of the photovoltaic panel 5 is fixedly connected to the top of the electrical box 1. The power generated by the photovoltaic panel 5 is regulated by the rectifier module and the charge / discharge management module of the intelligent control unit module 7 to charge the power lithium battery pack 6.

[0051] In this embodiment of the invention, the electrical box 1 can be divided into three functional compartments by a partition: a power lithium battery pack compartment 101, an intelligent control unit module compartment 102, and an intelligent micro-projector compartment 103. The front of the compartment is closed by an openable electrical box cover 104. One end of the electrical box cover 104 is connected by a hinge, and the other end is locked by a buckle. This provides reliable dust and water protection and facilitates maintenance personnel to quickly open the box for module inspection and replacement.

[0052] In one implementation, an audible and visual alarm unit module 4 is installed at the upper end of the bracket 2 to provide flashing lights and sound prompts during the operation and maintenance process. This module is controlled by the intelligent control unit module 7 and can trigger flashing lights and voice prompts when receiving remote operation instructions or equipment operation instructions sent by mobile terminals to remind nearby personnel to pay attention to safety. For example, when a pole malfunctions and needs emergency repair, the intelligent operation and maintenance management cloud platform sends an instruction to the intelligent control unit module 7 of the intelligent electronic pole number plate of the malfunctioning pole. The intelligent control unit module 7 controls the audible and visual alarm unit module 4 to activate the "fault alarm mode". The fault alarm mode means that the audible and visual alarm unit module 4 flashes red light rapidly and intermittently issues a voice prompt "Power failure, pay attention to safety" at a frequency of 1 time / 10 seconds.

[0053] As one implementation, a meteorological sensor unit module 3 is installed at the upper end of the bracket 2. The meteorological sensor unit module 3 is used to collect parameters such as ambient temperature, humidity, and light intensity, and feeds the collected data back to the intelligent control unit module 7 in real time, providing a basis for adjusting the tilt angle of the photovoltaic panel 5. Furthermore, by collecting weather data through the meteorological sensor unit module 3, auxiliary decision support can also be provided for the operation and maintenance process. For example, before the start of routine operations, the weather forecast can be made through the meteorological sensor unit module 3 to adjust the operation and maintenance operation time.

[0054] As one implementation method, the smart electronic pole number can also be equipped with an NFC card 9, which is connected to the smart control unit module 7 via a data cable. The NFC card 9 is independently installed on the pole, approximately 1.5 meters above the ground, for easy access by maintenance personnel. The front of the NFC card 9 is coated with a unique QR code corresponding to the pole. For example, when maintenance personnel touch the NFC card 9 using an NFC-enabled mobile terminal, the mobile terminal sends a device identification request to the NFC card 9. Upon receiving the request, the NFC card 9 transmits a trigger signal and its stored device ID to the smart control unit module 7 in real time via the data cable. After verifying the validity of the device ID, the smart control unit module immediately wakes up the smart micro-projector 8 and controls it to project the identification information.

[0055] In one implementation, the bracket 2 is fixed to one side of the electrical box 1. The mounting plate of the bracket 2 has a long, straight slot, and through the cooperation of a U-shaped rod 202 and an anti-slip nut 201, it achieves a quick and secure connection with various pole structures such as cement poles, angle steel towers, or steel pipe towers. Specifically, the U-shaped rod 202 passes sequentially through the preset installation position on the pole, the long, straight slot of the bracket 2, and is finally locked by the anti-slip nut 201. This long, straight slot design allows for adjustable installation height of the device on the pole, enhancing adaptability.

[0056] In one implementation, a solar tracking power supply system is installed on the top of the electrical box 1, including a photovoltaic panel 5, a stepper motor 501, and an electric push rod telescopic mechanism 502. One end of the photovoltaic panel 5 is fixed to the top of the electrical box 1 via a pivot; the other end of the photovoltaic panel 5 is hinged to the inclined surface at the top of the electric push rod telescopic mechanism 502. The electric push rod telescopic mechanism 502 has a hinge in the middle, and the angle of the photovoltaic panel 5 is changed by the inclined surface at the top of the electric push rod telescopic mechanism 502 when it extends or retracts. The electric push rod telescopic mechanism 502 is driven by the stepper motor 501 and can dynamically adjust the tilt angle of the photovoltaic panel 5 under the control of the intelligent control unit module 7 to maximize the solar energy collection efficiency.

[0057] In one embodiment, a smart operation and maintenance management system for high-voltage distribution lines based on the smart electronic pole number plate is provided, including a smart operation and maintenance management cloud platform; the smart operation and maintenance management cloud platform includes a business system interface module for interfaceing with the power safety production management system to obtain work order information; an asset management module for constructing a three-dimensional digital twin model corresponding to the physical poles to realize the visual management of the poles and related equipment, including real-time updates and display of information such as pole number, location, and equipment status; and a work scheduling module for sending work instructions to the smart electronic pole number plate and pushing work information to the work supervisor and relevant area operation and maintenance personnel.

[0058] In a further improved embodiment, the intelligent operation and maintenance management cloud platform establishes bidirectional data interaction with the intelligent control unit module 7 of each intelligent electronic pole number through a communication network. Furthermore, the intelligent operation and maintenance management cloud platform undergoes deep data interface-level integration with the power company's existing "safety production management system" (or "work order system"), transforming the intelligent electronic pole number into an intelligent execution node in the business process. This enables the coordinated control of operation and maintenance business instructions, personnel operations, and equipment. The specific implementation process is as follows:

[0059] When power distribution lines need to add or remove intermediate towers due to renovation, expansion, or other reasons, during the work permit issuance stage, the work permit is issued in the safety production management system and transferred to the pending execution state. The intelligent operation and maintenance management cloud platform automatically obtains key information from the work permit through the business system docking module, including but not limited to the tower number, work content, planned work time period, work supervisor's identity information, and safety measures requirements. Based on the above information, the operation scheduling module of the intelligent operation and maintenance management cloud platform issues a "work preparation" instruction to the intelligent electronic pole number plate of the target tower. The intelligent control unit module 7 of the intelligent electronic pole number plate receives the instruction. The intelligent operation and maintenance management cloud platform pushes the work information to the mobile terminal APP of the work supervisor, on-site workers, and other relevant operation and maintenance personnel in the line area (including specific work content, precise tower location, safety precautions, etc.) through the operation scheduling module, forming a three-dimensional safety protection system of "point (single tower) - line (entire line) - surface (regional operation and maintenance network)," fundamentally preventing the risk of accidentally entering live areas and other work risks, replacing traditional telephone or verbal notifications.

[0060] Upon receiving the "Work Preparation" command, the intelligent control unit module 7 of the intelligent electronic pole number plate controls the intelligent micro-projector 8 to project the "Work Preparation" sign, thus providing proactive safety warnings before the operation. If the target pole's intelligent electronic pole number plate is equipped with an audible and visual alarm unit module 4, the audible and visual alarm unit module 4 is simultaneously activated to start the "Work Preparation Mode." The Work Preparation Mode refers to the audible and visual alarm unit module 4 slowly flashing yellow light and intermittently issuing a voice prompt "Electric work, pay attention to safety" at a frequency of once every 10 seconds. The audible and visual alarm unit module 4 and the intelligent micro-projector 8 continue to operate until the maintenance personnel arrive on site.

[0061] During the operation initiation phase: After the maintenance personnel arrive at the site, they can send an operation initiation command to the intelligent control unit module 7 of the target pole through any of the following interaction methods: mobile terminal APP of the intelligent operation and maintenance management cloud platform, near-field sensing NFC card 9, mobile terminal connected to intelligent control unit module 7 via Bluetooth, or scanning the QR code on NFC card 9. This will control the intelligent micro-projector 8 to project a "operation start" sign. If the intelligent electronic pole number is equipped with an audible and visual alarm unit module 4, the audible and visual alarm unit module 4 will be controlled to start the "operation start mode". The operation start mode means that the audible and visual alarm unit module 4 flashes red light quickly and intermittently emits a voice prompt "Power operation, pay attention to safety" once every 10 seconds. The above operation commands are fed back to the intelligent operation and maintenance management cloud platform in real time through the communication network. The asset management module automatically updates the operation status of the corresponding pole in the digital twin model constructed by the intelligent operation and maintenance management cloud platform (such as "operation in progress", "paused", "completed"), so that the back-end management personnel can remotely monitor the operation progress.

[0062] After the operation is completed, the maintenance personnel send an operation completion application to the intelligent operation and maintenance management cloud platform via a mobile terminal; if the intelligent electronic pole number plate is equipped with an NFC card 9, the operation completion instruction is sent via NFC near-field interaction, and the asset management module updates the pole status synchronously.

[0063] In a further improved embodiment, when tower information needs to be changed in batches, the tower sequence that needs to be renumbered can be selected on the intelligent operation and maintenance management cloud platform, and the new name and number information can be sent in batches to the intelligent control unit module 7 of the corresponding intelligent electronic pole number plate. The operation information can also be sent to the operation and maintenance personnel. When the operation and maintenance personnel are on patrol, they can trigger the projection display of the new information on each tower through a mobile terminal APP or NFC near-field interaction, without having to climb the pole to replace the physical sign.

[0064] In a further improved embodiment, when a power pole malfunctions and requires emergency repair, the dispatch center receives a power outage report and quickly locates the suspected faulty pole through the intelligent operation and maintenance management cloud platform. It then sends a command to the intelligent control unit module 7 of the intelligent electronic pole number plate on the faulty pole. The intelligent control unit module 7 controls the audible and visual alarm unit module 4 to activate the "fault alarm mode." The fault alarm mode involves the audible and visual alarm unit module 4 flashing red light rapidly and intermittently emitting a voice prompt "Power failure, be careful" at a frequency of once every 10 seconds. It also controls the intelligent micro-projector 8 to project the words "Fault Repair," achieving rapid location and warning, guiding repair vehicles and personnel to the location quickly, and simultaneously warning surrounding personnel to stay away. This is faster and has a greater warning distance than manually hanging signs.

The description of the above embodiments is only for the purpose of helping to understand the methods and core ideas of the embodiments of this application.
