Description

They are an indispensable basic element in line inspection, fault location, equipment maintenance and daily dispatching.

[0003] Currently, most pole number plates are made of aluminum alloy. These plates are molded in one piece, and their content cannot be changed. If the content needs to be changed, the plate must be remade, which takes a long time and cannot meet the need for timely updates. When the line is relocated or the operation mode is adjusted, there may be situations where the pole number plates of dozens or even hundreds of poles need to be replaced. Replacing the pole number plates requires two people to work together, one holding the ladder and the other climbing to work at height, which carries the risk of falling from height. Two people can replace the pole number plates of 30 to 40 poles a day, which consumes a lot of manpower, material resources, and financial resources.

Detailed Implementation

[0017] The technical solutions of 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, Figure 1 The present invention provides a smart pole number plate for power distribution networks, comprising: Power module 1; Display module 2 is connected to power module 1 via a connection module; The main controller, which is electrically connected to the display module 2; and The communication module is bidirectionally connected to both the remote management platform and the main controller. The power module 1, the display module 2, the main controller and the communication module are integrated inside the pole number plate; The communication module transmits uplink status data to the remote management platform and receives pole number instructions sent by the remote management platform; The main controller sends the pole number command received by the communication module to the display module 2 to display the pole number, and also sends the uplink status data to the communication module. The power module 1 and the connection module, as well as the connection module and the display module 2, are detachable connections. The power module 1 includes: The photovoltaic panel is fixed to the power module 1 at a predetermined tilt angle; A photovoltaic panel controller, which is connected to the photovoltaic panel via wires; The battery is placed in a battery slot at the bottom of the power module 1. The battery slot is equipped with an openable and closable sealing plate. The battery is connected to the photovoltaic panel controller via wires. The predetermined tilt angle is 45°. The smart pole number plate of the power distribution network is triangular in shape and made of ABS plastic shell. The triangular structure design achieves excellent wind resistance and self-cleaning effect. Rainwater can flow away quickly along the slope. At the same time, the ABS material has good mechanical strength, weather resistance and insulation properties, effectively protecting the internal electronic components from the corrosion of the harsh outdoor environment. like Figure 1 and Figure 2 As shown, the smart pole number plate of the power distribution network adopts a split modular design. The overall structure mainly includes a power module 1, a display module 2, and a connecting module connecting the two. This design allows the power module 1 and the display module 2 to be disassembled and replaced independently, greatly reducing maintenance costs and complexity. The connection between the power module 1 and the connecting module, as well as between the connecting module and the display module 2, is detachable, specifically a mechanical structure combining a slide rail and a snap-fit, and integrates a waterproof electrical connector to ensure a stable physical connection and reliable power transmission. The power module 1 is the energy source for the entire device, as described above. Figure 3Its core components include a photovoltaic panel, a photovoltaic panel controller, and a battery. The photovoltaic panel is fixed to the top casing of the power module 1 via grooves at a predetermined tilt angle of 45 degrees upwards. This tilt angle is calculated and optimized to maximize the solar radiation intensity received by the photovoltaic panel throughout the day and in different seasons. Its theoretical solar irradiance can be expressed by the formula E = E0 * Cosθ is used for estimation, where E is the actual irradiance received by the photovoltaic panel, E0 is the local normal direct irradiance, and θ is the angle of incidence of sunlight. A 45-degree tilt angle can effectively reduce the annual average angle of incidence θ, thereby maximizing energy harvesting. The photovoltaic panel preferably uses monocrystalline silicon material with high conversion efficiency. The photovoltaic panel controller is connected to the photovoltaic panel and the battery through wires, and is responsible for managing the charging process of the photovoltaic panel to the battery, preventing overcharging and over-discharging. The battery is a high-energy-density lithium battery, which is placed in a dedicated battery slot at the bottom of the power module 1. The battery slot has an openable and closable cover plate. When the battery needs to be replaced, the maintenance personnel do not need to remove the entire pole number plate, but only need to lift the cover plate to replace it, making the operation extremely convenient. The display module 2 is a human-computer interaction interface for information presentation, as shown in the reference... Figure 4 It is connected to the power module 1 via a connection module and is continuously powered by the latter. The display panel of the display module 2 (preferably a low-power, high-contrast e-ink screen) is installed at a 45-degree angle downwards. This angle is ergonomically optimized to ensure that ground maintenance personnel can observe the screen from a near-vertical perspective and obtain the clearest visual effect. The display module 2 receives and executes display commands from the main controller through its internal drive controller. like Figure 3 , Figure 4 As shown, the specific structure of the connection module may include a groove 41 provided on the display module and a protrusion 42 provided at the corresponding position on the power module, which are connected by a slide rail. The smart pole number plate for the power distribution network also includes: A battery monitoring module is electrically connected to the main controller. The battery monitoring module acquires battery fault information, and the main controller controls the communication module to send the fault information to the management platform. A tilt monitoring module, electrically connected to the main controller, acquires pole tilt information. The main controller then controls the communication module to send the tilt information to the management platform. The communication module establishes bidirectional communication connections with both the remote management platform and the main controller, preferably using 4G communication technology which offers wide coverage and high speed. During operation, the communication module is responsible for receiving all control commands (mainly pole number display commands) issued by the remote management platform and transmitting them to the main controller. Simultaneously, it is also responsible for sending the uplink status data collected by the main controller to the remote management platform. The main controller is responsible for parsing and executing the pole number commands from the communication module, controlling the display module 2 to update and display the corresponding pole number information. In addition, the main controller is responsible for polling each monitoring module: the battery monitoring module monitors the battery's voltage, internal resistance, and other parameters in real time. Once an abnormality is detected (such as voltage below the set undervoltage threshold V_low), it generates battery fault information and reports it to the main controller; the tilt monitoring module (usually a MEMS tilt sensor) continuously measures the pole's tilt angles θ_x and θ_y in the X and Y axes. When the tilt angle in either direction exceeds the safety threshold θ_th (e.g., 10 degrees), it generates pole tilt information. Upon receiving these alarm messages, the main controller immediately controls the communication module to package them as uplink status data and send them to the management platform, thereby achieving proactive early warning of equipment health and pole safety. The smart pole number plate for the power distribution network also includes: A lighting module, electrically connected to the main controller, includes a sensor 51 and a backlight 52. The lighting module 5 is electrically connected to the main controller and includes a sensor 51 and an LED backlight 52. The sensor 51 uses infrared sensing technology to detect whether anyone is approaching the pole number plate. When a human infrared signal is detected, the main controller will trigger the LED backlight 52 distributed on the back of the display module 2 to light up, achieving an intelligent lighting effect of "lights on when people are present, lights off when people leave," which greatly facilitates pole number identification at night or in dimly lit environments. The smart pole number plate for the power distribution network also includes: The fixing module 3 is located above the power supply module 1 and below the display module 2. The fixing module 3 is provided with a mounting structure for connecting to the crossarm or clamp. like Figure 5 As shown, the fixing module 3 is located above the power module 1 and below the display module 2. It is provided with an installation structure, specifically screw holes. When installed on the main line, the upper and lower screw holes are firmly connected to the crossarm by screws; when installed on the branch line, it is fixed to the pole by clamps. This design provides a high degree of installation flexibility.

[0019] Example 2, Figure 6 An adaptive pole number modification system is proposed, including: The distribution network smart pole number plate; a management platform, communicatively connected to the communication module of the distribution network smart pole number plate; wherein, the management platform includes: a topology acquisition unit, configured to acquire a line topology diagram of the distribution line; an instruction generation unit, configured to generate a pole number display instruction based on the line topology diagram; and an instruction issuing unit, configured to issue the pole number display instruction to the main controller of the corresponding distribution network smart pole number plate through the communication module; The main controller is configured to control the display module (2) to update and display the corresponding pole number information in response to the pole number display command. The topology acquisition unit is further configured to automatically acquire the adjusted new route topology map from the map model system when the operating mode is adjusted. The instruction generation unit and instruction issuing unit are configured accordingly to: generate new pole number display instructions based on the new line topology map and issue them to the corresponding smart pole number plates to complete the adaptive modification of pole numbers. The specific steps are as follows: The pole number adaptive modification system consists of multiple distribution network smart pole number plates and a remote management platform. The management platform maintains communication connections with the communication modules of all smart pole number plates. Its workflow is as follows: The topology acquisition unit of the management platform first obtains the first line topology map of the distribution line under normal power supply mode (e.g., "110kV Fuyang Substation 10kV Shengli Road 189 Line") from the power grid's map model system. Figure 7 As shown; the instruction generation unit automatically generates the corresponding pole number display instruction based on this first line topology map; the instruction issuing unit sends this pole number instruction in batches to all relevant smart pole number plates along the line through the communication module. The main controller of each pole number plate responds to this instruction and controls its display module 2 to display a normal power supply mode pole number such as "Sheng 189-015". Figure 8 As shown, When a line is relocated or its operation mode is adjusted, the system initiates an adaptive modification process. The topology acquisition unit automatically retrieves the adjusted new line topology map from the map model system (e.g., "110kV Quanbei Substation 10kV Nanjing Road 245 Line"). The instruction generation unit and instruction issuing unit then work together to generate new pole number display instructions based on this new line topology map and immediately issue them to the affected smart pole number plates. Upon receiving the new instructions, these pole number plates will quickly and automatically update their display content to a backup power supply mode pole number, such as "Nan 245-015". Figure 9 As shown, the entire process requires no manual on-site intervention, achieving real-time, accurate, and synchronous updates of pole number information. When the operating mode is restored, the system will automatically trigger the above process again to restore the pole number to the display of the normal power supply mode.
