[0072] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0074] With the continuous development of power systems, the safe and stable operation of distribution network lines has become increasingly important. These lines cover a wide and complex area, making global monitoring impossible and often leading to damage from external forces such as mechanical collisions and human sabotage.

[0075] External damage is one of the important factors affecting the safe operation of distribution network lines. Its unpredictability and destructiveness pose a great challenge to the stable operation of the power system.

[0076] Traditional methods of preventing external damage often rely on manual inspections and monitoring, which are not only inefficient but also make it difficult to detect well-hidden acts of sabotage.

[0077] Based on the above-mentioned technical problems, the inventor's technical concept is as follows: Given that many cases of external damage are caused by engineering vehicles crossing low overhead power lines and construction excavators operating haphazardly on construction sites, by deploying low-power wireless beacon units on engineering vehicles and setting up high-power wireless beacon units and external damage prevention gateways in the protection zones of the power distribution lines, when a vehicle enters the area, the low-power wireless beacon unit broadcasts a signal to establish a connection in a low-power manner. After security verification, the information is transmitted stably and uploaded to the cloud platform by the high-power wireless beacon unit (with the external damage prevention gateway as an intermediary). This accurately locates the vehicle and its protection zone, triggering an early warning, thus achieving early prevention of external damage and ensuring the safety of overhead power lines.

[0078] Based on the above technical concepts Figure 1 This is a schematic diagram of the structure of the early warning system for preventing damage from external forces provided in the embodiments of this application, as shown below. Figure 1 As shown, the early warning system for preventing external damage includes: a low-power wireless beacon unit, at least one high-power wireless beacon unit (four units are shown in the figure, namely high-power wireless beacon #1, high-power wireless beacon #3, high-power wireless beacon #2, and high-power wireless beacon #4), and a gateway for preventing external damage.

[0079] Should Figure 1 In the diagram, there are black dots indicating external damage (i.e., the areas corresponding to the solid lines) to indicate specific locations or areas where power facilities are easily damaged due to external factors (such as engineering vehicles crossing overhead lines with low installation heights, or excavators working arbitrarily on construction sites). These are the areas to prevent external damage.

[0080] The low-power wireless beacon units are installed in engineering vehicles; the high-power wireless beacon units are installed in the areas of the distribution network lines protected against external damage.

[0081] For example, taking high-power radio beacon #2 as an example, the dashed area where it is located represents the area where a low-power radio beacon unit can establish a connection; the actual signal range that the low-power radio beacon unit can capture when broadcasting online messages is shown in the dashed area corresponding to the low-power radio beacon unit. That is, in Figure 1 In the process, when the dashed area corresponding to the low-power wireless beacon unit intersects with the dashed area where the high-power wireless beacon #2 is located, there is a possibility of successfully establishing a connection.

[0082] Additionally, the anti-tamper gateway is used to receive information from high-power wireless beacons and send it to the cloud platform. Detailed implementation of this embodiment is described in the following embodiments and will not be repeated here.

[0083] Optional, Figure 2 This is a schematic diagram of the structure of a low-power wireless beacon unit provided in an embodiment of this application, as shown below. Figure 2 As shown, the low-power wireless beacon unit includes: a lithium battery, a power management module, a microcontroller unit (MCU), and a low-power Bluetooth module;

[0084] The lithium battery provides power, the MCU acts as the main controller of the device, and is used for data processing, signal acquisition, and module control; the power management module provides a stable and reliable power output to the functional modules of the device; and the low-power Bluetooth module is used for wireless data interaction.

[0085] Optional, Figure 3 This is a schematic diagram of the structure of a high-power wireless beacon unit / anti-external-force gateway provided in an embodiment of this application, as shown below. Figure 3 As shown, the high-power wireless beacon unit / anti-vandalism gateway includes: a lithium battery, a charge and discharge management module, an MCU, a low-power Bluetooth module, a photovoltaic charging module, and a wireless module (such as 4G).

[0086] The lithium battery provides electrical energy; the MCU acts as the main controller of the device, used for data processing, signal acquisition, and module control; the charge / discharge management module is used for automatic control of charging and discharging; the photovoltaic charging module (photovoltaic module) generates electrical energy in the presence of sunlight and automatically steps up and down to output it to the device; the low-power Bluetooth module is used for wireless data interaction; and the 4G wireless module is used for data transmission and remote command reception.

[0087] It should be understood that in the embodiments of this application, low power consumption in the low power wireless beacon unit means that the power and other resources consumed during use are low, for example, the power consumed per hour is lower than a first preset threshold; high power in the high power wireless beacon unit means that the signal strength is high during use, so that the low power wireless beacon unit can capture it in time, for example, the power value is greater than a second preset threshold.

[0088] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0089] Figure 4 This is a schematic diagram of the interactive process of the early warning method for preventing damage from external forces provided in the embodiments of this application, as shown below. Figure 4 As shown, the method includes:

[0090] Step 41: The low-power wireless beacon unit broadcasts online messages at a first preset time interval and with a first preset transmission power;

[0091] Among them, the online message is used to trigger the high-power wireless beacon unit to establish a connection with the low-power wireless beacon unit.

[0092] In this step, when an engineering vehicle carrying a low-power wireless beacon unit enters the area corresponding to the black spot that needs to be protected against external damage (i.e., the area for preventing external damage to the distribution network line), in order to prevent the engineering vehicle from causing external damage to the distribution network line in this area, the low-power wireless beacon unit is activated and broadcasts online messages to the outside at a first preset time interval and a first preset transmission power.

[0093] The first preset time interval and the first preset transmission power can both be pre-configured by technicians and can be modified based on actual conditions; for example, in one possible implementation, the first preset transmission power is the minimum transmission power of the low-power wireless beacon unit.

[0094] For example, in practical implementation, multiple high-power wireless beacons can be deployed to cover the black spot damaged by external force.

[0095] Step 42: The high-power wireless beacon unit acquires the online messages sent by the low-power wireless beacon unit;

[0096] In this step, when the engineering vehicle enters the area corresponding to the high-power wireless beacon unit, the high-power wireless beacon unit can detect the online messages sent by the low-power wireless beacon unit.

[0097] Step 43: The high-power wireless beacon unit generates a first reply message based on the online message and the first identification key of the high-power wireless beacon unit;

[0098] In this step, after the high-power wireless beacon unit receives the online message, it generates a first reply message based on the online message and the first identification key of the high-power wireless beacon unit. This first reply message is used to send a verification message confirming the connection to the low-power wireless beacon unit.

[0099] In one possible implementation, the first identification key here can be the first private key corresponding to the high-power wireless beacon unit. The online message is encrypted based on the first private key, and then a first reply message is generated. In practice, the low-power wireless beacon unit should pre-store the first public key corresponding to the high-power wireless beacon unit. Whether the first reply message can be decrypted using the first public key can determine whether the low-power wireless beacon unit and the high-power wireless beacon unit can communicate securely.

[0100] Step 44: The high-power wireless beacon unit sends the first reply message to the low-power wireless beacon unit;

[0101] In this step, the high-power wireless beacon unit broadcasts a first reply message, which is then received by the low-power wireless beacon unit.

[0102] In this implementation, there is a possibility that other unknown devices may obtain the first reply message. However, since the message is generated based on the first identification key, there is a possibility that other unknown devices may be unable to verify it or may not verify it accurately, thus increasing security.

[0103] Step 45: After the low-power wireless beacon unit verifies the first reply message, it sends the first information to the high-power wireless beacon unit at the second preset transmission power.

[0104] The first information enables the high-power wireless beacon unit to send the first identifier of the low-power wireless beacon unit and the second identifier of the high-power wireless beacon unit in the first information to the cloud platform; the second preset transmission power is greater than the first preset transmission power.

[0105] In this step, the low-power wireless beacon unit verifies the first reply message, for example, by decrypting the first reply message using the first public key. If the decryption is successful, the first reply message is considered to have been verified, and the connection between the low-power wireless beacon unit and the high-power wireless beacon unit is considered legitimate. At this time, in order to ensure the accuracy and efficiency of data transmission, the first information is sent to the high-power wireless beacon unit at the second preset transmission power.

[0106] The second preset transmission power can be pre-configured by technicians and can be modified based on actual conditions; for example, in one possible implementation, the second preset transmission power is the maximum transmission power of the low-power wireless beacon unit.

[0107] Optionally, the first information may be generated by encrypting the first identifier of the low-power wireless beacon unit based on the second private key in the second identification key in the low-power wireless beacon unit, and correspondingly, the second public key in the second identification key is reserved in the high-power wireless beacon unit.

[0108] Optionally, the high-power wireless beacon unit sends the first information to the cloud platform through a damage-resistant gateway.

[0109] In this implementation, the high-power wireless beacon unit determines the anti-external force damage gateway with the same network number based on the network number, and sends the first information to the anti-external force damage gateway. The anti-external force damage gateway forwards the first information to the corresponding cloud platform based on the routing information in the routing table.

[0110] The first information can be forwarded to the corresponding cloud platform via the 4G module in the anti-external damage gateway.

[0111] In other implementations, the high-power wireless beacon unit can also directly transmit to the corresponding cloud platform based on the 4G module in the high-power wireless beacon unit.

[0112] Furthermore, broadcasting is stopped after the first response message fails to be verified.

[0113] In this implementation, if the first reply message cannot be decrypted, the verification is considered to have failed, and the connection to the device corresponding to the first reply message is considered to have failed.

[0114] Furthermore, after the first reply message is verified, a heartbeat message is broadcast to the outside at a set interaction frequency to maintain the connection between the high-power wireless beacon unit and the low-power wireless beacon unit.

[0115] If the low-power wireless beacon unit does not receive the second reply message of the heartbeat message, it stops broadcasting and waits for the next time point corresponding to the set interaction frequency before broadcasting the heartbeat message again.

[0116] Step 46: The cloud platform determines the area to be protected from external damage and vehicle information based on the first identifier and the second identifier of the high-power wireless beacon unit;

[0117] In this step, the cloud platform records the location of at least one high-power wireless beacon unit configured in the network line, and records the vehicle information of the engineering vehicle configured with at least one low-power wireless beacon unit. Therefore, the cloud platform can determine the corresponding vehicle information based on the first identifier of the low-power wireless beacon unit, and can determine the area where the engineering vehicle is currently located from external force damage based on the second identifier of the high-power wireless beacon unit.

[0118] The vehicle information may include: the type of engineering vehicle, the driver, size information, etc.

[0119] Step 47: The cloud platform triggers an early warning based on the information of the area and vehicles to be protected from external damage.

[0120] In this step, the cloud platform generates an early warning based on vehicle information and the area where the engineering vehicle is located, and triggers the early warning to relevant personnel.

[0121] In one possible implementation, the warning prompts relevant management personnel to be aware that engineering equipment (i.e., engineering vehicles) have entered the area where external damage has occurred. Depending on the situation, they should contact the relevant responsible persons or go to the site to supervise the construction to prevent external damage to the power distribution network.

[0122] The early warning method for preventing external damage provided in this application embodiment is applied to low-power wireless beacon units and high-power wireless beacon units configured in engineering vehicles. The method includes: broadcasting an online message at a first preset time interval and a first preset transmission power, the online message being used to trigger the high-power wireless beacon unit to establish a connection with the low-power wireless beacon unit, the high-power wireless beacon unit being set in the external damage prevention area of ​​the distribution network line; receiving a first reply message sent by the high-power wireless beacon unit, the first reply message being determined by the high-power wireless beacon unit based on the online message and the first identification key of the high-power wireless beacon unit; after the first reply message is verified, sending first information to the high-power wireless beacon unit at a second preset transmission power, so that the high-power wireless beacon unit sends the first identifier of the low-power wireless beacon unit and the second identifier of the high-power wireless beacon unit in the first information to a cloud platform, the cloud platform determining the external damage prevention area and vehicle information based on the first identifier and the second identifier of the high-power wireless beacon unit, and triggering an early warning prompt based on the external damage prevention area and vehicle information, the second preset transmission power being greater than the first preset transmission power. In this technical solution, the low-power wireless beacon unit broadcasts online messages at a first preset time interval and a first preset transmission power. This operation can actively emit signals with low energy consumption, effectively triggering the high-power wireless beacon unit in the distribution network line's anti-external damage zone to establish a connection, ensuring signal detection while reducing energy consumption. After receiving the first reply message generated based on the online message and the high-power wireless beacon unit's first identification key, the low-power wireless beacon unit verifies the identification key, ensuring the security and reliability of the connection. After successful verification, it sends the first information at a higher second preset transmission power, ensuring the stability and accuracy of information transmission, enabling the high-power wireless beacon unit to send the low-power wireless beacon unit's first identifier to the cloud platform. The cloud platform combines the first identifier and the high-power wireless beacon unit's second identifier to accurately determine the anti-external damage zone and vehicle information, thereby triggering an early warning. This enables timely monitoring and early warning of vehicles entering the anti-external damage zone, helping to prevent external damage to the distribution network line in advance and ensuring the safe operation of the line.

[0123] Based on the above embodiments, the first information further includes: a second identification key for the low-power wireless beacon unit, then... Figure 5 A flowchart illustrating the early warning method for preventing damage from external forces provided in this application embodiment. Figure 1 ,like Figure 5 As shown, before step 45, this high-power wireless beacon unit can also perform the following:

[0124] Step 51: After the first information is verified, send an uplink message based on the first identifier and the second identifier to the cloud platform through the anti-external force damage gateway;

[0125] In this step, after the above verification is passed, it indicates that the high-power wireless beacon unit and the low-power wireless beacon unit have been successfully paired. This proves that the engineering vehicle corresponding to the low-power wireless beacon unit has entered the distribution network line corresponding to the high-power wireless beacon unit. Based on the first identifier of the low-power wireless beacon unit and the second identifier of the high-power wireless beacon unit, an uploading message is generated and sent to the cloud platform.

[0126] The first information is verified by the high-power wireless beacon unit decrypting it based on the second public key in the second identification key. If the decryption is successful, the first information is considered to have been verified.

[0127] Optionally, step 51 may include the following implementation:

[0128] Step 1: Identify the gateway configured with a network number related to the cloud platform to prevent external damage;

[0129] In this implementation, the high-power wireless beacon unit determines the anti-external damage gateway that matches the reserved network number.

[0130] Step 2: Send the upload message to the anti-external damage gateway so that the anti-external damage gateway can send the upload message to the cloud platform based on the preset routing table.

[0131] In this implementation, the generated upload message is sent to the anti-external force damage gateway, so that the anti-external force damage gateway sends the upload message to the corresponding cloud platform through the routing information in the routing table based on the preset routing table.

[0132] Step 52: If the third reply message of the uploaded message is not received, control the high-power wireless beacon unit to generate fault information;

[0133] In this step, if no third reply message is received from the cloud platform (e.g., through the anti-external damage gateway) within a preset time period, it is assumed that there is a connection problem in the high-power wireless beacon unit or the reporting line, and fault information can be generated directly.

[0134] This fault message directly indicates that there is an engineering vehicle in the high-power wireless beacon unit. Personnel involved in the engineering vehicle should pay attention to protecting the power supply line during operation.

[0135] The early warning method for preventing external damage provided in this application embodiment is applied to a high-power wireless beacon unit. The method includes: after successful verification of the first information, sending an upload message based on a first identifier and a second identifier to a cloud platform through an anti-external damage gateway; if a third reply message is not received, controlling the high-power wireless beacon unit to generate fault information. In this scheme, when the second identification key is successfully verified, it means that the secure connection between devices is confirmed. At this time, sending an upload message based on the first identifier and the second identifier to the cloud platform through the anti-external damage gateway aims to accurately transmit key information to the cloud platform, so that the cloud platform can integrate this identification information and associate it with the corresponding device and the anti-external damage area, thereby achieving effective monitoring of the area's status. If a third reply message is not received, it indicates an abnormality in the data transmission process. Controlling the high-power wireless beacon unit to generate fault information in this case allows for timely feedback of data transmission faults, facilitating rapid problem location by technicians, ensuring the stability and reliability of data transmission throughout the system, and ensuring that the real-time monitoring and early warning function of the anti-external damage area is not interfered with by data transmission problems, maintaining the system's effective prevention and control of potential external damage risks.
