Technical Field

[0001] This invention relates to the field of power grid technology, and in particular to an intelligent self-updating electronic pole number system and control method based on Internet of Things (IoT) technology. Background Technology

[0002] In the power and telecommunications sectors, power poles serve as core supporting infrastructure, and their pole number plates are crucial for identification, operation and maintenance management, and fault location. Currently, the widely used traditional physical pole number plates are made of metal or plastic, which suffers from low update efficiency and is prone to errors.

[0003] When lines are switched, poles are added or removed, maintenance personnel need to carry new signs and climb to the site to replace them. This process is time-consuming and labor-intensive, and is prone to errors due to manual copying, which can lead to mismatches between pole numbers and poles, causing maintenance accidents.

[0004] Taking a 10kV distribution line as an example, a single pole number replacement requires the cooperation of 2-3 maintenance personnel, and the operation of a single pole takes an average of 20-40 minutes. Moreover, in complex terrain (such as mountainous and forested areas), the transportation costs of personnel and equipment increase significantly, resulting in low pole number update efficiency. Summary of the Invention

Maintenance personnel on the ground apply force to the unlocking component by holding a lever, driving the unlocking component, which in turn links the elastic buckle to disengage it from the slot, thereby realizing the remote disassembly of the electronic pole number terminal.

[0009] In one possible implementation, the electronic pole numbering system also includes a handheld terminal and a co-source system; the handheld terminal establishes communication connections with both the electronic pole numbering terminal and the co-source system to transmit numbering information or location information of the electronic pole numbering terminal.

[0011] Secondly, embodiments of the present invention provide a control method for an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology, applicable to the electronic pole number system in any possible implementation of the first aspect. The control method includes: responding to synchronous operation of a handheld terminal by maintenance personnel, receiving an updated pole data file sent by a source system; generating number information based on the pole data file and a preset electronic map of the poles, the number information including the identifier of the electronic pole number terminal to be updated, the updated number code, and the location information of the electronic pole number terminal to be updated; responding to an update mode input by maintenance personnel, selecting a dual-mode communication mode based on the update mode, and transmitting the number information to the electronic pole number terminal to be updated; receiving an update status response from the electronic pole number terminal; the update status response including update success or update failure; if the update status response is update success, performing path planning based on the location information of each electronic pole number terminal and the location information of the maintenance personnel to generate an inspection path to instruct the maintenance personnel to conduct on-site confirmation.

[0012] In one possible implementation, license plate information is generated based on pole data files and a pre-defined electronic map of poles. This includes: parsing the pole data files to extract the updated license plate codes, location information, and route information for each pole; matching the parsed license plate codes and location information with the identifiers and location information of registered electronic pole license plate terminals on the electronic map to update the association list of license plate codes, terminal identifiers, and location information; determining the identifier of the electronic pole license plate terminal to be updated and the updated license plate code based on the association list and the change information in the pole data files; generating a verification code based on the identifier and location information of the electronic pole license plate terminal to be updated and the updated license plate code; and generating license plate information for each electronic pole license plate terminal based on the identifier and location information of the electronic pole license plate terminal to be updated, the updated license plate code, and the verification code.

The process also includes: in response to the maintenance personnel's selection of marking an anomaly in the detailed information menu, a fault work order is generated based on the location information of the target pole number, the number code, the anomaly type, and the current time, and uploaded to the same source system.

[0015] Thirdly, embodiments of the present invention provide a control method for an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology, applicable to the electronic pole number system in any possible implementation of the first aspect.

However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details.

The term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0023] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the steps or modules listed, but may optionally include other steps or modules not listed, or may optionally include other steps or modules inherent to such process, method, product, or device.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0025] As described in the background section, pole number updates during line relocation are inefficient and prone to errors. When a line is relocated, or a pole is added or removed, maintenance personnel must carry newly made physical pole numbers to the site and climb to the designated height on the pole using climbing equipment (such as foot straps or ladders) to replace them. Taking a 10kV distribution line as an example, a single pole number replacement requires the collaboration of 2-3 maintenance personnel, and the operation on a single pole takes an average of 20-40 minutes. In complex terrain (such as mountainous or forested areas), the transportation costs of personnel and equipment increase significantly. This process is not only time-consuming and labor-intensive, but more importantly, manual replacement is prone to errors in pole number copying and confusion regarding pole-to-tower correspondences, leading to mismatches between pole numbers and actual poles. This can cause misjudgments in subsequent maintenance operations (such as fault repair and line maintenance), and in severe cases, may result in line outages, equipment damage, and other safety accidents.

[0026] The inability to locate pole positions in real time poses significant challenges to operation and maintenance. Traditional pole number plates lack positioning functionality, and pole location information relies solely on paper drawings or manual memorization by maintenance personnel. This data is prone to delays and loss. In field inspection scenarios, especially in areas without clear landmarks or with complex terrain, maintenance personnel must meticulously check drawings one by one to determine the location of the target pole. On average, finding each pole takes more than 30 minutes, drastically reducing the efficiency of line fault inspection. The traditional physical pole number plates have poor day and night adaptability and are difficult to identify. They rely on ambient light reflection for identification. At night or in low-light environments (such as cloudy days or inside tunnels), they have no active light emission capability. Maintenance personnel need to use handheld flashlights or other auxiliary lighting equipment to shine the light at close range (within 1-2 meters) to see the pole number clearly. This is not only cumbersome, but may also lead to identification errors due to the angle of the light. In daylight, under strong direct sunlight, some pole number plates are prone to glare, which also makes the pole number blurry. The identification distance is shortened to within 5 meters, which cannot meet the needs of long-distance rapid identification.

[0027] Installation and maintenance rely on working at heights, posing significant safety risks. The installation and replacement of traditional pole number plates both require maintenance personnel to climb to heights. Whether using footholds or ladders, this falls under the category of dangerous high-altitude work. Industry statistics show that falls from power poles account for over 25% of all accidents in the power maintenance sector. Furthermore, high-altitude work demands strict adherence to personnel qualifications and weather conditions, further increasing the cost and time of installation and maintenance. Simultaneously, the height of some poles (such as high-voltage line towers exceeding 15 meters) exponentially increases the difficulty and risk of high-altitude work, hindering maintenance efficiency.

[0028] In summary, existing pole numbering systems have significant technical deficiencies in information updates, location management, day and night recognition, and installation and maintenance. There is an urgent need for an intelligent pole numbering system that can achieve remote self-updating, real-time positioning, clear day and night recognition, and eliminate the need for high-altitude operations, in order to solve the pain points in the industry's operation and maintenance management.

[0029] To address the aforementioned technical issues, this invention provides an in-depth analysis of the pain points in industry operations and maintenance. Based on the core design concept of "IoT collaboration + hardware and software integration," a complete technical solution is gradually formed. The specific conceptualization process is as follows: 1. A breakthrough in concept from "manual replacement" to "remote self-update".

[0030] To address the pain points of low efficiency and high error rate in manual pole climbing for replacement, the first consideration was "whether pole number information can be transmitted remotely." Considering that most poles in the field are in environments without wired networks, LoRa / NB-IoT dual-mode communication was chosen (balancing long distance and wide coverage). At the same time, to ensure data consistency, a data closed loop of "source-middle-terminal" needs to be established. Therefore, an "APP (middle interaction) - + terminal (execution)" architecture was designed. Through standardized data export and verification mechanisms, data transmission errors are avoided, ultimately achieving remote automatic updates.

[0031] 2. Concept of functional integration from "no positioning" to "precise navigation".

[0032] To address the difficulty of pole location, and considering that maintenance personnel need to locate poles on-site, the positioning function needs to be combined with mobile terminals—GPS / BeiDou dual-mode positioning is selected, and navigation functions are integrated into the APP to directly guide personnel to the site; at the same time, the positioning data needs to be associated with the pole number, so the positioning coordinates are included when exporting data from the same source system to achieve a one-to-one correspondence between "pole number and location" and solve the problem of "finding the pole but not being able to identify the number".

[0033] 3. From "single display" to "day and night adaptation" display technology selection concept.

[0034] To address the challenges of daytime and nighttime identification, and analyzing the shortcomings of traditional pole number plates—namely, the lack of active illumination at night and glare during the day—the display module needed to simultaneously meet the requirements of "self-illumination at night" and "anti-glare during the day." An OLED self-illuminating screen (low power consumption, adjustable brightness) was chosen to solve the nighttime problem, while an AG anti-glare coating (suppressing reflections) was used to address the daytime issue. Furthermore, considering outdoor power consumption limitations, an automatic brightness adjustment logic was designed (adjusting brightness based on ambient light sensor data) to reduce energy consumption while maintaining readability.

[0035] 4. Structural design concept from "high-altitude operation" to "ground operation" To address the risks of working at heights, the core principle is to "complete installation and maintenance on the ground"—structurally, this involves "how to connect and disassemble the terminal to the tower without climbing." A quick-release snap-fit ​​structure is designed, paired with an extended operating rod, ensuring that maintenance personnel can access the snap-fit ​​from the ground. Simultaneously, the tower mounting base can be pre-installed on the ground, further simplifying the operation process and completely eliminating the need for working at heights.

[0036] It will break through the limitations of traditional pole number plates as "physical static identifiers" and upgrade them into "Internet of Things dynamic intelligent terminals". Through multi-module integration and system collaboration, it will fundamentally solve industry pain points and provide intelligent solutions for pole operation and maintenance management.

[0037] like Figure 1 As shown, this embodiment of the invention provides an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology. The system includes an electronic pole number terminal.

[0038] In this embodiment, the electronic pole number plate terminal includes a display module 20 and a communication module, as well as a processing module connected to the display module 20 and the communication module respectively. The display module 20 is disposed on the front of the electronic pole number plate terminal and includes an LED self-emissive display screen covered with an AG anti-glare coating. The communication module includes a LoRa communication submodule and an NB-IoT communication submodule. The processing module communicates with the handheld terminal of the maintenance personnel through the communication module to realize the transmission of number plate information and displays the number plate information through the display module.

[0039] This invention provides an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology. By setting up an electronic pole number terminal for each pole, the communication module overcomes the physical limitations of geography and manual operation, allowing maintenance personnel to remotely issue update commands without going to the site. This avoids pole climbing for replacement and personnel scheduling and transportation, reducing pole number update time and improving update efficiency. The processing module works in conjunction with the communication and display modules to automate the entire process of receiving, processing, and displaying pole number information, eliminating rework delays caused by human error and further improving update efficiency. This invention, through IoT technology, achieves remote communication, automated processing, and optimized display through technical synergy, transforming pole number updates from a high-risk, long-cycle on-site operation into an efficient and precise remote operation, solving the problem of low update efficiency and significantly improving overall efficiency.

[0040] Optionally, the electronic pole number plate terminal also includes: a positioning module connected to the processing module; the positioning module is used to locate the location information of the electronic pole number plate terminal; the processing module transmits the location information of the electronic pole number plate terminal to the handheld terminal through the communication module.

[0041] Optionally, the electronic pole number terminal also includes: a quick-release structure 30 located on the back of the electronic pole number terminal; the quick-release structure 30 includes a fixing base, an elastic buckle, and an unlocking component; the fixing base is pre-installed on the pole tower 10 at a set height, the elastic buckle is fixed to the back of the electronic pole number terminal, and the elastic buckle cooperates with the slot on the fixing base to realize the remote fastening and installation of the electronic pole number terminal; the unlocking component is located on the back of the electronic pole number terminal, and the unlocking component is linked with the elastic buckle. The maintenance personnel apply force to the unlocking component by holding a lever on the ground, driving the unlocking component and linking the elastic buckle to disengage the elastic buckle from the slot, thereby realizing the remote disassembly of the electronic pole number terminal.

[0042] Optionally, the electronic pole number plate system also includes a handheld terminal and a corresponding system; the handheld terminal establishes communication connections with the electronic pole number plate terminal and the corresponding system respectively to realize the transmission of number plate information or location information of the electronic pole number plate terminal.

[0043] Optionally, the electronic pole number terminal also includes an ambient light sensor connected to the processing module; the ambient light sensor is used to collect the light intensity of the environment in which the electronic pole number terminal is located; the processing module adjusts the brightness of the display screen of the display module according to the light intensity collected by the ambient light sensor.

[0044] It should be noted that this invention utilizes the Internet of Things (IoT) collaboration among a unified system graphical maintenance mechanism, a handheld terminal (e.g., a mobile app), and an electronic pole numbering terminal. This, combined with hardware structure optimization and software control logic, constructs a complete intelligent self-updating electronic pole numbering system. Within the unified system, the single-line diagram is updated in real-time after line changes or maintenance, and can also be exported. Therefore, this system comprises two core components: a handheld terminal and an electronic pole numbering terminal. These two components achieve closed-loop control through standardized data interaction and IoT communication. The architecture and interaction process are as follows: Figure 2 As shown.

[0045] The electronic pole number terminal is a field execution unit that integrates five major functional modules: display, power supply, positioning, communication, and structure. The specific design is as follows: Display Module 10: It adopts a 5.5-inch high-brightness LED self-emissive display screen with an AG anti-glare coating on the screen surface. In night mode, the display screen automatically turns on low-power self-emissive mode, achieving clear recognition within 10 meters without external lighting. In strong daylight, the anti-glare coating can effectively suppress reflections caused by direct sunlight, ensuring long-distance recognition within 20 meters. At the same time, the display screen supports static pole number display and dynamic status prompts (such as "to be updated" and "normal"), enhancing the dimensions of information transmission.

[0046] Power supply module 40: It adopts a combination of "monocrystalline silicon solar panel (power 10W, conversion efficiency ≥23%) + lithium iron phosphate energy storage battery (capacity 5000mAh, cycle life ≥2000 times)" and is equipped with MPPT (maximum power point tracking) charging management circuit. The solar panel is fixed to the top of the electronic pole number terminal by an adjustable bracket, and the tilt angle can be adjusted according to the latitude of the installation area (0-45 degrees) to ensure that the daily charging amount meets the 72-hour battery life requirement of the electronic pole number terminal. In cloudy or low light environment, the energy storage battery automatically supplies power and has overcharge, over-discharge and short circuit protection functions to adapt to complex outdoor climate.

[0047] Positioning module: integrates GPS / BeiDou dual-mode positioning chip (positioning accuracy ≤10 meters, cold start time ≤30 seconds), supports real-time acquisition of the geographical coordinates of the pole; positioning data is uploaded to the mobile APP in real time through the communication module, while the electronic pole number terminal stores the most recent 10 positioning data locally to avoid data loss due to signal interruption.

[0048] Communication module: It adopts a LoRa / NB-IoT dual-mode communication scheme. The LoRa mode is suitable for low-power data transmission over long distances in the wild (communication distance ≥1km in open environment), while the NB-IoT mode is suitable for real-time data interaction in areas with operator network coverage. The module supports a wake-up mechanism (sleep current ≤10μA, wake-up response time ≤100ms), which is activated only when receiving update instructions or uploading location data to reduce power consumption. Shell and Installation Structure: The shell of the electronic pole numbering terminal is made of ABS+PC flame-retardant material, with an IP65 dustproof and waterproof rating, suitable for outdoor working environments of -30℃ to 70℃; the installation structure adopts a "quick-release buckle + extended operating rod adapter interface" design: the back of the electronic pole numbering terminal is equipped with 3 elastic buckles, which can be quickly fastened to the pre-set fixing seat (can be installed on the ground) of the pole tower 10; when the electronic pole numbering terminal needs to be replaced, the maintenance personnel can remove the electronic pole numbering terminal by moving the buckle unlocking piece through the extended operating rod (3-5 meters in length), without having to climb to a height.

[0049] The handheld terminal, namely the smart pole number sign mobile APP, serves as the intermediate interaction unit between the "same source system and the terminal". It supports both Android and iOS systems and its core functions are as follows: Data import and parsing: It supports downloading single-line diagram data files exported from the same source system via Bluetooth, WiFi or cloud, automatically parsing the pole number and the corresponding pole tower 10's positioning coordinates and line information, and generating a "pole number-location-line" association list; Remote broadcast update: The APP broadcasts pole number update instructions (including target pole number, check code, and update time) to electronic pole number terminals within a specified area via the LoRa / NB-IoT module; it supports two modes: "single terminal precise update" (specified by the terminal's unique ID) and "multi-terminal batch update" (selecting electronic pole number terminals by defining geographical areas); Electronic pole number terminal response feedback: After receiving the update command, the electronic pole number terminal automatically verifies the data integrity (through verification code). If the verification passes, it updates the pole number on the display screen and sends a "update successful" signal to the APP; if the verification fails, it sends a "update failed" signal, and the APP prompts the maintenance personnel to rebroadcast. Location navigation and maintenance assistance: The APP calls the location data uploaded by the electronic pole number terminal to display the real-time location of pole 10 on the electronic map and supports voice navigation (to guide maintenance personnel to the target pole); at the same time, it can record the inspection route of maintenance personnel and pole fault information to realize closed-loop management of maintenance.

[0050] like Figure 3 As shown, this embodiment of the invention also provides a control method for an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology. Applied to... Figure 1 The handheld terminal of the electronic pole numbering system shown includes steps S101-S105 in its control method.

[0051] S101, in response to the synchronization operation of the handheld terminal by the maintenance personnel, receives the updated tower data file sent by the same source system.

[0052] In some embodiments, after the line relocation is completed, maintenance personnel update the single-line diagram of the line in the same-source graphic maintenance system. After confirming that the pole and tower attribute information (pole number, location coordinates, etc.) is correct, they export the pole and tower data file. Maintenance personnel download or import the above single-line diagram file through a mobile APP. The APP automatically parses the data, generates an association list containing "pole number - location coordinates - line information", and marks the location of each pole and tower on the electronic map.

[0053] S102. Generate license plate information based on pole data files and preset electronic maps of poles.

[0054] In this embodiment of the application, the license plate information includes the identifier of the electronic pole license plate terminal of the license plate to be updated, the updated license plate code, and the location information of the electronic pole license plate terminal of the license plate to be updated.

[0055] As one possible implementation, step S102 can be specifically implemented as steps S1021-S1025.

[0056] S1021. Parse the tower data file and extract the updated license plate code, location information, and line information of each tower.

[0057] S1022. Match the parsed license plate code and location information with the identifiers and location information of the registered electronic pole license plate terminals on the electronic map, and update the association list of license plate code-terminal identifier-location information.

[0058] S1023. Based on the change information in the association list and pole data file, determine the identifier of the electronic pole number terminal to be updated, and the updated number code.

[0059] S1024. Generate a verification code based on the identification and location information of the electronic pole number terminal to be updated, and the updated number code.

[0060] S1025. Based on the identifier and location information of the electronic pole number terminal to be updated, the updated number code, and the verification code, generate the number information for each electronic pole number terminal.

[0061] S103. In response to the update mode input by the maintenance personnel, based on the update mode, select the dual-mode communication mode and transmit the license plate information to the electronic pole license plate terminal of the license plate to be updated.

[0062] S104. Receive the update status response transmitted back by the electronic pole number terminal.

[0063] In some embodiments, the update status response includes update success or update failure.

[0064] S105. If the update status response is successful, then based on the location information of each electronic pole number terminal and the location information of the maintenance personnel, a path planning is performed to generate an inspection path to instruct the maintenance personnel to conduct on-site confirmation.

[0065] As one possible implementation, step S105 can be specifically implemented as steps S1051-S1053.

[0066] S1051. Display the location information of all registered electronic pole number terminals and the currently displayed number code on the electronic map.

[0067] S1052. In response to the operation and maintenance personnel clicking the target pole number icon, display the detailed information menu of the target pole number.

[0068] In some embodiments, the details menu includes: navigate here, view historical maintenance records, and flag anomalies.

[0069] S1053. In response to the operation and maintenance personnel's selection operation of navigating to this location in the detailed information menu, the map service is invoked to generate an inspection route from the operation and maintenance personnel to the target pole number based on the location information of the target pole number and the location information of the operation and maintenance personnel.

[0070] Optionally, the control method for the intelligent self-updating electronic pole number system based on Internet of Things technology provided in this embodiment of the invention further includes step S201 after step S105.

[0071] S201. In response to the operation and maintenance personnel's selection of marking an anomaly in the detailed information menu, a fault work order is generated based on the location information of the target pole number, the number code, the anomaly type and the current time, and uploaded to the same source system.

[0072] Optionally, embodiments of the present invention also provide a control method for an intelligent self-updating electronic pole number system based on Internet of Things (IoT) technology. Applied to... Figure 1 The electronic pole numbering system shown has an electronic pole numbering terminal, and the control method includes steps S301-S304.

[0073] S301, Receive license plate information sent by the handheld terminal.

[0074] S302. Verify the license plate information and obtain the verification result.

[0075] S303. If the verification result is successful, the display module of the electronic pole license plate terminal is controlled to display the license plate code in the license plate information, and an update status response indicating successful update is sent to the handheld terminal through the communication module.

[0076] S304. If the verification result is that the verification fails, the current display content of the display module remains unchanged, and an update status response indicating the update failure is sent to the handheld terminal through the communication module to trigger the handheld terminal to prompt the maintenance personnel to reissue the update command.

[0077] For example, maintenance personnel select the update mode (single terminal / multiple terminals) in the APP, confirm the target pole number, and click "broadcast update". The APP sends an update command to the target terminal through the communication module (LoRa / NB-IoT). The command content includes: target terminal ID (or area range), new pole number, data verification code, and command validity period (default 5 minutes).

[0078] The communication module of the electronic pole number terminal listens for update commands in real time. When it receives a command that matches its own ID (or is within a specified area), it first verifies the data integrity through a verification code. If the verification is successful, the electronic pole number terminal controls the display module to update the pole number and sends "update successful" feedback to the APP through the communication module. If the verification fails (e.g., due to data corruption), it sends "update failed" feedback, and the APP pops up a window prompting a retry.

[0079] After the update is completed, maintenance personnel can view the feedback results from the electronic pole number terminal through the APP to confirm the update status. If on-site verification is required, the APP provides navigation services based on the location data of the electronic pole number terminal to guide maintenance personnel to the pole site and visually confirm whether the pole number display is correct. At the same time, the APP can record the update operation log for easy reference by personnel.

[0080] This invention, through the above-mentioned technical solution, specifically addresses four major pain points of existing pole numbering systems, achieving the following significant beneficial effects: 1. The efficiency of pole number updates has been greatly improved, and the error rate has been significantly reduced.

[0081] No manual pole climbing is required for pole number replacement. Pole numbers are updated remotely via an app, reducing the update time for a single pole from the traditional 20-40 minutes to 10 minutes, improving efficiency by over 95%. At the same time, the data source is standardized and exported from the same system, avoiding errors from manual copying. The error rate for pole number updates is reduced to 0, completely solving the problem of "pole number mismatch with actual pole".

[0082] 2. Operation and maintenance management is made intelligent, and positioning efficiency is significantly improved.

[0083] With dual-mode positioning and APP navigation, the time for maintenance personnel to locate target towers has been reduced from more than 30 minutes to less than 5 minutes, improving inspection efficiency by 80%. The same system synchronizes tower location and status data in real time. After importing the data into the APP, the APP can be used to accurately dispatch maintenance tasks and optimize routes, reducing emergency repair response time by 30% and promoting the transformation of maintenance from "passive" to "proactive".

[0084] 3. Optimized day and night recognition performance, clearly distinguishable in all weather conditions.

[0085] With its self-illuminating design at night and anti-glare design during the day, the recognition distance reaches 10 meters at night (no flashlight required) and 20 meters in strong daylight conditions. Compared with traditional pole number plates (≤2 meters at night, ≤5 meters during the day), the recognition distance is increased by 4-5 times. In addition, the brightness of the display screen is adjustable to adapt to different lighting environments, ensuring fast recognition at long distances in all weather conditions and reducing the complexity of inspection operations.

[0086] 4. Installation and maintenance do not require working at heights, reducing both safety risks and costs.

[0087] The ground-mounted quick-release installation structure eliminates the need for climbing equipment for initial installation and subsequent replacements. Maintenance personnel can complete the operation while standing at the base of the tower, completely avoiding the risk of falling from heights. At the same time, it saves on the transportation costs of equipment such as ladders and foot catches, reducing the maintenance cost of a single tower by more than 60% and shortening the maintenance time to less than 10 minutes.

[0088] 5. It boasts outstanding energy-saving and compatibility advantages, making it suitable for complex outdoor environments.

[0089] Powered by solar energy and energy storage batteries, it requires no external power source, making it suitable for field and agricultural environments. A daily charge provides 72 hours of continuous operation, and it can work for 3-5 days in cloudy or rainy weather. The electronic pole number terminal has an IP65-level protective shell and an operating temperature range of -30℃ to 70℃, making it suitable for complex climates such as mountainous areas, forest areas, and areas with high temperatures or extreme cold. At the same time, the system supports different voltage levels (10kV-500kV) and different types of poles (power and communication), ensuring strong compatibility and wide applicability.
