Technical Field
[0001] This invention relates to the field of intelligent monitoring technology, and in particular to an intelligent grounding box monitoring method and system based on Bluetooth communication. Background Technology
[0002] Intelligent grounding boxes are key devices for the safe operation of power systems in scenarios such as tunnels. They communicate with a mobile app via Bluetooth to achieve status monitoring, data interaction, and inspection management, relying on three core requirements: Bluetooth connection stability, communication security, and accurate anomaly identification. With the popularization of IoT technology in industrial scenarios, the deployment scale of intelligent grounding boxes continues to expand, and the requirements for intelligent inspection efficiency, data security, and fault early warning are increasing. Traditional technical solutions are no longer suitable for the needs of high-density deployment and use in complex environments.
[0003] In existing technologies, Bluetooth connections often fail to consider device topology and personnel movement, making them susceptible to signal interference in densely populated scenarios. This can lead to misjudgment of connection targets, response delays, and a significant reduction in inspection efficiency. Communication encryption often uses fixed or default keys, lacking a dynamic update mechanism, making it vulnerable to cracking and hijacking, posing serious security risks. Anomaly detection often relies on single parameter thresholds, failing to consider parameter trend changes and weight differences, making it difficult to identify hidden risks and resulting in a high false alarm and false negative rate. Summary of the Invention

Based on the device identifiers of the mobile terminal and the target grounding box, and combined with the current timestamp, a dynamic key is generated. The dynamic key is then used to perform two-way authentication with the target grounding box to establish an encrypted communication channel. After successful verification, the real-time status information and historical records of the target grounding box are obtained through an encrypted communication channel and stored locally; Based on the acquired status information, combined with preset thresholds at all levels and parameter change trends, a comprehensive anomaly determination is made. When an anomaly is determined, an alarm message is generated and issued. When the mobile device is in an environment with network connectivity, the locally stored status information and historical records are uploaded to the server.
[0006] Secondly, the present invention provides an intelligent grounding box monitoring system based on Bluetooth communication, comprising: The mobile terminal is used to perform multi-dimensional feature evaluation of broadcast signals from multiple surrounding grounding boxes, and select a target grounding box to establish a Bluetooth connection based on the evaluation results; it uses a dynamic key to perform two-way authentication with the target grounding box to establish an encrypted communication channel; after successful authentication, it obtains the real-time status information and historical records of the target grounding box through the encrypted communication channel and stores them locally; based on the obtained status information, it performs a comprehensive anomaly judgment by combining preset thresholds at various levels and parameter change trends, and generates and issues alarm information when an anomaly is determined; it uploads the locally stored status information and historical records to the server. The server is used to receive and process permission request requests initiated by the mobile terminal, and to receive, store and manage the status information and historical records uploaded by the mobile terminal.
[0007] The intelligent grounding box is used to monitor and store the operating status and alarm information of the equipment in real time, and respond to the connection request of the mobile terminal. After establishing an encrypted communication channel based on two-way authentication, it sends the real-time status information and historical records to the mobile terminal.

Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Next, combined Figure 2 This embodiment provides a detailed description of a smart grounding box monitoring method based on Bluetooth communication.
[0018] The intelligent grounding box monitoring method described in this embodiment consists of three parts working together: a mobile terminal, a server terminal, and an intelligent grounding box terminal deployed in the tunnel. The intelligent grounding box is responsible for real-time acquisition and local storage of operational data; the mobile terminal, as a tool for on-site tunnel operations, establishes near-field communication with the grounding box via Bluetooth to acquire data and perform status analysis; the server terminal interacts with the mobile terminal via the mobile network, responsible for access control, data aggregation, and global monitoring. These three components, through a combination of Bluetooth near-field transmission and mobile network backhaul, together form a distributed monitoring system adapted to network-free tunnel environments.
[0019] Among them, the mobile terminal refers to a portable smart terminal device equipped with a dedicated monitoring application (APP), typically a smartphone.
[0020] To achieve a rapid and reliable connection between the mobile terminal and the target grounding box during inspection, this embodiment first proposes an equipment optimization mechanism to identify signal strength and connect to the grounding box with the highest signal strength. After maintenance personnel activate the automatic inspection function of the APP, the system integrates multi-dimensional features to evaluate signal strength, adapting to the complex electromagnetic environment and equipment layout within the tunnel, ensuring a high initial connection success rate and a smooth inspection path.
[0021] To overcome the problems of Bluetooth signal interference, overlap, and instantaneous fluctuations caused by the complex electromagnetic environment and dense equipment layout in tunnels, and to improve the accuracy of equipment identification, connection stability, and inspection efficiency, this embodiment specifically introduces two factors in signal strength assessment: equipment topology inference and movement state prediction. These factors are used to integrate spatial location relationships and personnel movement intentions into the equipment selection logic, thereby more accurately identifying the actual target equipment to be inspected in the signal-mixed tunnel environment, reducing false connections and reconnections, and ensuring the continuity and efficiency of the inspection path.
[0022] Specifically, when the APP activates the automatic inspection function, it first performs a rapid scan of the surrounding environment to obtain broadcast information from all detectable grounding boxes, including device IDs and instantaneous RSSI. Based on the preset approximate spacing of equipment installations within the tunnel, the scanned devices are initially clustered and grouped to exclude invalid devices with weak signals or those that are clearly distant reflected signals.
[0023] For candidate devices after initial screening, the following four dimensions of features are calculated and fused in real time to generate a dynamic connectivity score: 1. Signal quality dimension An improved weighted smooth RSSI and link quality assessment strategy is adopted to select equipment with high signal quality.
[0024] Specifically, the Bluetooth received signal strength indicator value is continuously collected, and a moving average filtering algorithm is used to reduce instantaneous fluctuation interference to obtain a stable signal strength value. : ; in, It is a smoothing coefficient that can be dynamically adjusted according to the degree of environmental interference.
[0025] Next, a signal-to-noise ratio (SNR) estimation factor is introduced to indirectly assess the impact of current channel quality on the connection of specific devices by analyzing the stability of broadcast packet reception. Specifically, the variance of signal strength over a recent period is calculated as a reference indicator of connection stability. ; In the formula, This represents the signal strength value acquired in the i-th acquisition. Indicates all within the preset time period The smaller the variance, the higher the stability, and the more suitable the device is for establishing a reliable connection.
[0026] in, and The weights are adjustable.
[0027] Equipment selection is based on the following weighted scoring formula: ; 2. Device Topology Dimension A lightweight topology map based on the tunnel layout is preset. This map does not require precise coordinates, but only records the installation sequence and relative position of each grounding box, such as device A being 50 meters upstream of device B.
[0028] The app uses a built-in inertial sensor (IMU) to allow maintenance personnel to input the starting point or perform topology positioning by identifying the first connected device at the start of the inspection.
[0029] When multiple devices with similar signal strengths are detected, the device that best matches the current topology prediction location is prioritized. For example, when traveling along a tunnel, it is more likely to connect to the grounding box that is about to be reached, rather than the grounding box that has already been passed behind.
[0030] 3. Mobility State Prediction Dimension The app uses a built-in inertial sensor (IMU) to continuously analyze the movement speed and direction of maintenance personnel.
[0031] Based on the topology map, predict the grounding box that is most likely to enter its effective connection range within a preset time period, such as 3-5 seconds.
[0032] By introducing a predictive proximity factor, additional scoring is given to devices whose current signal is not the strongest but are on a fast approach path, thereby enabling pre-connection preparation and reducing connection latency.
[0033] 4. Historical connection success rate dimension Based on the historical number of successful connections for each grounding box Number of attempts Calculate its connection reliability weights to characterize historical performance: ; Ultimately, the dynamic connectivity score is derived by weighting the above dimensions, and a connection is initiated with the device that scores the highest. ; in, The signal quality score is given. The topology matching score is calculated based on the deviation between the current device and the predicted topology location. The mobility prediction score quantifies the strength of the trend of maintenance personnel approaching the target equipment and its prediction accuracy based on the mobility state prediction results. Score historical performance; , , , The weights are dynamic and adaptively adjusted based on environmental complexity (such as equipment density); in densely populated areas, the weights are increased. and Weights are assigned to address signal scrambling issues.
[0034] In practical applications, as one implementation method, maintenance personnel launch the app at the tunnel entrance, select the inspection route, and the system loads a simplified topological map of the corresponding road segment. The app scans the environment, filtering out unreliable signal sources. It calculates four-dimensional features of candidate devices in real time, runs a scoring model, and selects the optimal target device. Afterward, a secure connection is established to acquire device data.
[0035] In this embodiment, by dynamically scoring and selecting and connecting the grounding box with the highest comprehensive score, the limitations of a single signal strength index can be overcome, maximizing the connection success rate and data transmission reliability in complex tunnel environments, thereby improving the overall efficiency and reliability of automatic inspection.
[0036] Furthermore, after selecting the target grounding box, communication is established between the mobile device and the target grounding box. Before establishing communication, a connection is first established with the server for authorization. The APP application sends a permission request to the server via HTTP.
[0037] After obtaining authorization from the server, the app interacts with the smart grounding box via a proprietary Bluetooth encryption protocol. However, due to the lack of network coverage within the tunnel, traditional server-side dynamic key distribution mechanisms are unsuitable for this proprietary encryption protocol. Existing Bluetooth communication methods using fixed keys or simple pairing are susceptible to interception or spoofing.
[0038] To address this, this embodiment proposes a lightweight encryption protocol based on dynamic factor keys. By using dual verification of device hardware identifiers and timestamps, the security of Bluetooth communication is ensured, while also being adaptable to offline scenarios within tunnels.
[0039] The construction of the dynamic factor key begins by concatenating the mobile device's unique serial number (IMEI / SN) with the smart grounding box's Bluetooth MAC address to form the base key seed, denoted as . .
[0040] Next, a dynamic timestamp factor is introduced, where the current time's "hour + minute" value is denoted as T, and a dynamic synthesis key is generated through hash operations. : ; Dynamically synthesized keys Based on this, a fixed length is extracted as the final key. For example, obtaining a dynamically synthesized key. The first 16 bytes are used as the final key.
[0041] The dynamic factor key proposed in this embodiment can ensure that the key changes dynamically every hour, and even if a single communication is cracked, the key's validity period is extremely short.
[0042] Two-way verification between the mobile device and the smart grounding box is performed based on an encryption protocol.
[0043] Specifically, the mobile device first initiates a connection, reads the local device serial number and the target grounding box MAC address, and combines them with the current timestamp to generate... .
[0044] Will It is concatenated with the current timestamp T and broadcast to the grounding box via Bluetooth.
[0045] The grounding box analyzes the received T and verifies whether the timestamp is within the allowable deviation range. For example, the error range is set to ±3 minutes.
[0046] According to local storage Recalculate with the received T , and the received Comparison.
[0047] After successful verification, an acknowledgment signal is returned and an encrypted communication channel is established.
[0048] As one implementation method, when maintenance personnel bring their mobile device close to the grounding box, the mobile device's app automatically generates a dynamic key and sends a request. After verifying the validity of the timestamp, the grounding box confirms the user's identity through key matching and then initiates encrypted data transmission. If an abnormal connection attempt is detected (such as an incorrect key or timestamp exceeding the limit), the grounding box will log the event and trigger a local audible and visual alarm, indicating a potential security risk.
[0049] As one implementation, the grounding box can store the legitimate key records of the last 24 hours for post-event auditing; if three consecutive authentication failures are detected, the Bluetooth interface is automatically locked for 10 minutes to prevent brute-force attacks.
[0050] In this embodiment, a lightweight encryption protocol based on dynamic factor keys uses the mobile device serial number and the grounding box Bluetooth MAC address as the base seed, combined with timestamps to generate dynamic keys. This is suitable for offline tunnel scenarios and can avoid the risks of fixed keys. At the same time, the key changes dynamically every hour and has a short validity period. It is protected against cracking through two-way verification, and can also record logs and lock the interface to prevent brute-force attacks. It balances security and lightweight design, and ensures the security of Bluetooth communication.
[0051] Furthermore, after the app successfully connects to the grounding box via a Bluetooth proprietary encryption protocol, it automatically obtains the smart grounding box's status information and stores it in the app's internal database, such as... Figure 3 As shown, users can approach each smart grounding box in turn for inspection according to voice prompts. If an abnormality is detected in the grounding box, an alarm will be sent, such as a voice alert or vibration alert. After the inspection is completed, the data will be uploaded to the server for storage and timely maintenance and repair.
[0052] In this embodiment, for abnormal grounding box status, a comprehensive judgment is made using multi-parameter threshold judgment and trend early warning.
[0053] 1. Real-time parameter monitoring and threshold library The system monitors several key parameters of the grounding box, including but not limited to: cable joint temperature; humidity inside the box; insulation resistance value; operating current; and voltage fluctuation.
[0054] Each parameter has three threshold levels: normal range, warning threshold, and alarm threshold, which are adaptively adjusted according to the device model and environment.
[0055] 2. Trend Anomaly Detection The system performs short-term trend analysis on continuously collected data. If a parameter continues to rise or fall beyond a trend threshold within a set time period, the system will issue a warning even if the alarm limit has not been reached. ; in, The current value, The value from n periods ago, This is the threshold for trend change.
[0056] Real-time calculation of each parameter Comprehensive Abnormality Index :
[0057] in, The alarm threshold triggers the indicator function if The value is 1 if the alarm threshold is exceeded, and 0 otherwise. The warning threshold triggers the indicator function, if If the warning threshold is exceeded but the alarm threshold is not reached, the value is 1; otherwise, the value is 0. This is a trend warning function; it returns 1 if an abnormal trend is detected, and 0 otherwise. , , These are weighting coefficients that reflect the severity of different anomaly levels, typically... When any parameter If so, the parameter is determined to be abnormal.
[0058] In this embodiment, a weighted judgment combining multi-parameter three-level thresholds and trend early warning is used to accurately capture explicit anomalies exceeding the threshold and identify latent risks that have not reached the threshold but continue to worsen. The weights distinguish the anomaly levels, adapt to differences in equipment and environment, effectively reduce false alarms and missed alarms, help maintenance personnel quickly locate risks and handle them in a graded manner, achieve early detection and early intervention of faults, and reduce the probability of equipment failures escalating.
[0059] Furthermore, after completing the anomaly analysis, the current and historical data are incorporated into the long-term analysis framework. Through in-depth mining and pattern learning of historical data, risk patterns are identified, and predictive maintenance guidance is ultimately generated, thereby achieving an upgrade from a passive response to a proactive prevention-based operation and maintenance model.
[0060] like Figure 4 As shown (horizontal axis represents time), historical and real-time change curves of key parameters are plotted based on the abnormal parameter sequences obtained from monitoring. By analyzing these curves, the clustering patterns of alarm events in the time dimension can be identified, thereby pinpointing specific time periods where the alarm frequency is significantly higher than the average level, i.e., "time points prone to alarms".
[0061] Based on this, inspection strategies can be proactively optimized, and enhanced inspection plans and early warning tasks can be automatically generated for these high-risk periods. This concentrates maintenance resources on the most critical time and space nodes, realizing the transformation from uniform periodic inspections to risk-oriented precision maintenance, effectively reducing equipment failure rates and improving the overall safety of tunnel operation.
[0062] As one implementation method, the intelligent grounding box monitors and stores the operating status of the tunnel cable in real time, records alarm information, and communicates with the APP application via Bluetooth.
[0063] In this embodiment, the grounding box is a smart grounding box. The APP application communicates with the grounding box via Bluetooth; the mobile terminal communicates with the server via network communication.
[0064] As one implementation method, the server is used to verify the permissions of the APP application; receive and store the grounding box status information and historical records sent by the APP application, and uniformly maintain and manage all grounding box smart terminals.
[0065] The network communication between the APP and the server involves the APP sending requests to the server via HTTP to apply for permissions and upload the status and historical data of the smart grounding box, which are then uniformly stored and managed by the server.
[0066] This specific embodiment accurately selects target grounding boxes by introducing device topology relationship inference and movement status prediction, significantly improving connection efficiency in scenarios with dense multi-device environments. It employs a lightweight encryption protocol built with dynamic factor keys, using dynamic key updates and bidirectional verification to ensure wireless communication security. A comprehensive anomaly index is designed to achieve multi-parameter weighting and trend analysis, effectively reducing false alarm and missed alarm rates. This comprehensively improves the security, accuracy, and inspection efficiency of grounding box monitoring, providing reliable technical support for precise control and efficient maintenance of power system equipment.
