[0002] In power system operation and maintenance and emergency repair operations, portable short-circuit grounding wires are core protective equipment to ensure the safety of workers. However, in complex and changeable field environments, such as mountainous areas, forest areas, typhoons, and frost damage, the management of traditional grounding wires mainly relies on manual recording and tracking, which has problems such as inaccurate positioning, unclear status, and difficulty in finding them. This not only causes repair personnel to spend a lot of time searching for equipment, seriously affecting the efficiency of repairs, but also harbors serious safety hazards such as electric shock accidents caused by incorrect or missing grounding wires.

[0003] In existing technologies, although some positioning devices have been attempted to be used for tool management, they generally suffer from problems such as excessive power consumption, poor battery life, insufficient positioning accuracy, and large communication latency. They are difficult to meet the stringent requirements of long battery life, high reliability, and portability in power emergency scenarios. Especially in the field environment without a stable power supply, the battery life of the positioning device directly determines its availability. In complex terrain, positioning accuracy and communication reliability directly affect the speed of emergency response and operational safety.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] This invention provides a low-power portable positioning module based on the BeiDou Internet of Things (IoT), which is attached to an application device to achieve positioning of the application device, such as... Figure 1 As shown, the device includes: a main control unit, a BeiDou positioning module, an IoT communication module, a power management unit, and a structural housing. The main control unit is electrically connected to the BeiDou positioning module, the IoT communication module, and the power management unit, and these components are encapsulated within the structural housing. The BeiDou positioning module supports dual-frequency BeiDou signal reception to determine the current geographical location of the positioning module. The main control module generates location data for the application device based on the current geographical location. The IoT communication module supports NB-IoT and 4GCat.1 dual-mode communication to transmit location data to the user management platform. The main control unit integrates an accelerometer sensor to sense the movement status of the application device. The main control unit calculates the motion intensity of the application device based on the motion status and dynamically adjusts the location data reporting interval using an adaptive algorithm based on the motion intensity and the battery level monitored by the power management unit.

[0025] This invention provides a low-power portable positioning module based on the BeiDou Internet of Things (BIoT). Through an adaptive reporting algorithm running on the main control unit, it dynamically adjusts the data reporting frequency based on the application device's movement intensity and battery level, achieving intelligent power management and extending the device's availability in environments without stable power, thus ensuring continuous operation. Employing a positioning module supporting dual-frequency BeiDou signals effectively eliminates ionospheric delay errors, providing high-precision location information even in complex terrains such as mountainous and forested areas. Integrating a dual-mode communication module supporting NB-IoT and 4G Cat.1, it can adaptively select the optimal channel based on the network environment, ensuring real-time and stable transmission of location data to the user management platform. Furthermore, the high integration of various functional modules within a lightweight and robust casing achieves miniaturization and portability, facilitating rapid installation and removal from tools. Based on this, this application improves the efficiency and accuracy of tool management through precise real-time positioning, eliminates safety hazards, and provides a solid and reliable technical guarantee for the life safety of power workers.

[0026] The BeiDou positioning module is the core component for achieving high-precision positioning in this application. Specifically, it adopts the domestically produced CM162B high-precision positioning module. Its technical feature is that it supports dual-frequency signal reception of BeiDou B1I and B2a. By simultaneously receiving satellite signals from two frequency bands, it can accurately calculate and effectively suppress the propagation delay error caused by the signal passing through the ionosphere using the combination of dual-frequency observation values, thereby improving the key technology for positioning accuracy. The BeiDou positioning module used in this application can achieve a horizontal positioning accuracy better than 1 meter under static observation conditions, which fully meets the requirements of tools in scenarios such as power emergency repair. It meets the requirements for precise location management; in addition, the Beidou positioning module also has excellent signal acquisition capabilities, with a cold start sensitivity of up to -148dBm. This high sensitivity characteristic ensures that the module can still quickly acquire and stably lock onto Beidou satellite signals in complex environments with weak satellite signals (such as dense forests, deep canyons, or urban building obstruction areas), ensuring the availability and continuity of positioning services. The module's standard data update rate is 1Hz, that is, it outputs location information once per second. The refresh frequency can fully meet the real-time positioning and tracking needs of most emergency repair and field operation scenarios.

[0027] Specifically, in the above embodiments, the adaptive algorithm includes: statistically analyzing the shaking frequency of the application device within a preset time period based on a preset sliding window model; smoothing the shaking frequency using a Kalman filter algorithm to obtain a motion intensity value; and linearly mapping the motion intensity value to the reporting interval of location data.

[0028] In this embodiment, the adaptive algorithm is used to achieve the optimal balance between power consumption and positioning accuracy. The specific implementation process is as follows: Figure 2As shown, the algorithm includes: First, using the interrupt signal generated by the triaxial accelerometer integrated in the main control unit as a trigger, a sliding window model with a preset duration of 5 seconds is started. Under the sliding window model, the system can continuously and in real time count and calculate the shaking frequency of the device within the most recent 5-second time window. The shaking frequency reflects the intensity of the device's activity in a short period of time. Second, in order to eliminate possible noise and jitter in the raw sensor data and ensure the accuracy of motion state judgment, the algorithm introduces a Kalman filter algorithm to smooth the statistically obtained shaking frequency. After filtering, the system outputs a continuous, stable, and interference-resistant motion intensity value, which is quantized within the range of 0 to 5 Hz. Finally, the algorithm executes the key mapping logic to linearly map the smoothed motion intensity value to determine the reporting interval of the position data. The specific mapping relationship is that when the motion intensity value is high (close to 5 Hz), the smoothed motion intensity value is linearly mapped to determine the reporting interval of the position data. At Hz, the reporting interval is mapped to the shortest 1 second to ensure high-frequency position updates when the application device moves rapidly. When the motion intensity value is low, the reporting interval is linearly extended to the longest 8 seconds to maximize power saving. In particular, when the adaptive algorithm determines that the device is stationary by analyzing acceleration data, it will no longer rely on this mapping relationship, but will use a fixed 10-second reporting interval for data transmission. Therefore, based on the adaptive algorithm provided in this application, intelligent and refined power consumption control based on the actual motion state of the device is realized.

[0029] Specifically, in the above embodiments, the adaptive algorithm is configured to reduce the reporting frequency of location data when the battery level detected by the power management unit is lower than a preset threshold.

[0030] In this embodiment, the adaptive algorithm provided by this application not only dynamically adjusts based on the motion state of the application device, but also deeply integrates power management strategies to achieve more comprehensive battery life optimization. Specifically, the adaptive algorithm incorporates the battery level monitored in real-time by the power management unit as a key decision-making weight factor into the control logic. The system presets a low battery level threshold (e.g., when the battery level is below 20%). That is, when the algorithm continuously monitors and detects that the battery level is below the preset threshold, it immediately activates a power-saving protection mode. In this mode, the algorithm actively intervenes and reduces the reporting frequency of location data, such as... Figure 3 and Figure 4As shown, the intervention process is dynamic. It does not simply fix the reporting interval to an extremely long value, but rather dynamically extends the reporting interval based on the current motion state. For example, even if the application device is in motion, it should report at an interval of 2-3 seconds, but in low power mode, the reporting interval may be extended to 5-10 seconds or longer. Through this mechanism, when the system is low on power, it will sacrifice a certain degree of data real-time performance and prioritize power consumption control to the highest level, thereby effectively curbing the rapid consumption of power, significantly extending the overall battery life of the module during critical tasks, and ensuring that the positioning function is still available in special application scenarios. This constitutes a dual-insurance intelligent power consumption management system.

[0031] Specifically, in the above embodiments, the structural housing is detachably connected to the application device, and the structural housing is a sealed housing made of ABS plastic.

[0032] In this embodiment, the structural shell is the key physical carrier for achieving the portability, durability, and environmental adaptability of the positioning module. The structural shell in this application is made of ABS engineering plastic, which not only has sufficient mechanical strength to resist accidental drops and collisions during field operations, but also possesses good toughness to absorb impacts. Simultaneously, its low density makes it an ideal choice for achieving lightweight module design. The structural shell is a completely sealed enclosure, its internal space used to house and protect all core electronic components such as the main control unit, Beidou positioning module, IoT communication module, and power management unit. The shell's sealing performance achieves IP67 protection. The module is rated to completely prevent the intrusion of any dust (dustproof rating 6) and to prevent water intrusion under specified pressure and time conditions (usually 30 minutes at a depth of 1 meter), ensuring stable and reliable operation in harsh outdoor environments such as rain, snow, high humidity, mud, and even brief wading. To enable flexible deployment with application equipment, the structural shell is detachably connected to the application equipment, allowing the module to be easily and securely fixed to portable short-circuit grounding rods, safety helmets, or other tools, and easily removed after the task, facilitating the reuse and maintenance of the module.

[0033] Furthermore, the applicable equipment can be any one of the following: portable short-circuit grounding rod, disaster relief drone, individual soldier carrying equipment, mobile satellite communication terminal, emergency power generation vehicle, safety helmet, and insulated hand.

[0034] In this embodiment, the positioning module has strong versatility, and the corresponding application devices cover a variety of key equipment that require location tracking in field operations, including but not limited to any one of portable short-circuit grounding poles, disaster relief drones, individual soldier carrying equipment, mobile satellite communication terminals, emergency power generation vehicles, safety helmets, and insulating gloves, ensuring that the positioning module of this application has a wide range of application scenarios and practical value.

[0035] Furthermore, such as Figure 5 and Figure 6 As shown, the portable short-circuit grounding rod 2 includes a rod body 201, a grounding end clamp 202, and an insulating handle 203; the grounding end clamp 202 and the insulating handle 203 are respectively disposed at both ends of the rod body 201; the structural shell is detachably connected to the rod body 201 by mechanical buckles 3.

[0036] In this embodiment, taking a portable short-circuit grounding rod as an example, the portable short-circuit grounding rod is a core protective tool for ensuring the safety of maintenance personnel. Its structure mainly includes a slender rod body 201, a grounding end clamp 202 set at one end of the rod body 201, and an insulated handle 203 set at the other end of the rod body 201. In use, it is clamped to the power equipment to be maintained by the grounding end clamp 202 and connected to the grounding wire, thereby realizing the reliable grounding of the equipment. In order to combine the positioning module 1 of this application with the portable short-circuit grounding rod, the outer shell of the positioning module 1 is connected to the outer periphery of the rod body 201 by a detachable mechanical buckle 3. Specifically, the mechanical buckle 3 adopts a commercially available and reliable The bicycle seatpost clamp structure involves first fixing the positioning module 1 to the side of the seatpost clamp away from the clamp opening, then fitting the entire assembly onto the grounding pole 201 and tightening the locking screws. This connection method enables a quick, secure, and detachable connection, allowing the module to be flexibly deployed between different grounding poles, facilitating maintenance and reuse. More importantly, the locking mechanism of the mechanical buckle 3 provides sufficient clamping force to ensure that the positioning module 1 remains stably fixed to the pole 201 even under impacts caused by human shaking or vibration during grounding wire operation, and under long-term exposure to temperature cycles and humid environments outdoors. This prevents it from loosening or shifting, thus ensuring the continuity and accuracy of the positioning data.

[0037] Specifically, in the above embodiments, the power management unit includes a rechargeable lithium battery; the power management unit also includes a power optimization circuit, which is used to dynamically shut down idle pins and adjust the operating frequency of the main control unit, so that the positioning module enters a standby state.

[0038] In this embodiment, the power management unit (PMU) is the core of the positioning module's ultra-long battery life. It employs a low-power framework with deep hardware and software collaboration. Basic power is provided by a rechargeable lithium battery with a selectable capacity of 500mAh, ensuring the module can operate independently in outdoor environments without external power. Furthermore, the PMU integrates a power optimization circuit. Through hardware and software linkage, it implements multi-level power control strategies. At the hardware level, the power optimization circuit utilizes a dedicated power management chip (PMIC) and MOSFET switching devices to construct refined power domain management. It can dynamically shut down power to unused hardware pins or peripheral circuits according to the main control unit's instructions, thereby completely eliminating the static leakage current of these idle circuits. This is crucial for reducing standby power consumption. At the software level, the main control unit's operating system or low-level driver integrates a power management (PM) component. When the system completes a number of... After data collection, processing, and reporting, the main control unit actively enters a low-power command mode. At this time, the power optimization circuit works in conjunction with the main control unit, dynamically adjusting its operating frequency and voltage based on the current task load. The frequency is increased to ensure performance during complex tasks, and decreased to reduce dynamic power consumption during idle or light-load conditions. Finally, when the system has no tasks, the main control unit enters a deep low-power standby state under the control of the power optimization circuit. In this state, most circuits are shut down, with only a low-power timer running. The timer periodically wakes the main control unit to perform necessary tasks such as sending heartbeat packets, checking motion status, or reporting location data. After completing the task, it returns to standby mode. This application, through a comprehensive strategy of dynamic shutdown, dynamic frequency adjustment, and periodic standby, enables the power management unit to achieve extreme optimization of system power consumption, ensuring that the module's power consumption is controlled at extremely low levels under various operating conditions.

[0039] Specifically, in the above embodiments, the IoT communication module is integrated in the main control unit, and the IoT communication module supports the MQTT communication protocol.

[0040] In this embodiment, the IoT communication module is the key channel for remote transmission of positioning data. In a highly integrated preferred embodiment, the communication module is integrated inside the main control unit, for example, using an ultra-low power 4G Cat.1 communication chip such as the Air780EPS. This integrated design not only significantly reduces the overall size of the module, facilitating portability, but the ultra-low power consumption of the selected chip also plays a crucial role in extending the battery life of the entire positioning module. The IoT communication module supports multiple communication modes, with the preferred option being support for NB-IoT and 4G Cat.1 dual-mode communication. The system can automatically select the optimal communication mode based on the network signal strength and quality at the deployment site, i.e., using 4G in areas with good signal strength. Cat.1 achieves low latency (less than 500ms) and high throughput. In areas with weak signals or remote locations, it automatically switches to NB-IoT mode, utilizing its superior coverage and penetration capabilities to ensure uninterrupted communication, thus guaranteeing the reliability and continuity of data transmission. To further ensure data integrity, the communication module incorporates an automatic packet loss retransmission mechanism. When a data packet is detected as not being acknowledged, it is automatically retransmitted, effectively preventing data loss in complex and unstable outdoor network environments. At the communication protocol level, the IoT communication module supports the MQTT (Message Queuing Telemetry Transport) communication protocol. MQTT is a lightweight IoT message transmission protocol with advantages such as low bandwidth consumption, low network latency, and high reliability, making it suitable for scenarios like this one that require frequent transmission of small data packets. By supporting the MQTT protocol, the positioning module can establish a direct and efficient communication connection with a remote user management platform, uploading location data, device status, and operation logs in real time, enabling remote and centralized management of application devices.

[0041] Specifically, in the above embodiments, it further includes: a memory and a watchdog module; the memory is used to store the configuration parameters and operation logs of the application device; the watchdog module is used to perform a reset operation.

[0042] In this embodiment, the positioning module also includes a memory and a watchdog module, which work together to ensure persistent data storage and stable system operation, respectively. The memory is specifically an 8MB FLASH memory integrated within the module. It primarily stores configuration parameters necessary for device operation (such as communication server address, reporting frequency policy, user settings, etc.) and operational logs generated during device operation (such as positioning data records, communication status, system events, etc.). Because the FLASH memory is non-volatile, all stored data is retained even after the module is powered off or the battery is replaced. This ensures that critical location and status information can be reliably cached locally when the positioning module enters a deep low-power mode or is unable to upload data in real time due to a communication dead zone. Once communication is restored, the module can retrieve the cached log data. The data was reissued to the user management platform, ensuring data integrity and continuity. The watchdog module is an independent hardware circuit or a dedicated functional module integrated into the main control unit. Its core function is to monitor the program running status of the main control unit. During normal system operation, the main control unit software needs to periodically send a feed signal to the watchdog module within a preset timeout period to indicate that the program is running normally. If the main control unit's program crashes due to strong external electromagnetic interference, power fluctuations, or other abnormal reasons and fails to feed the watchdog in time, the watchdog module will determine that the system has failed and automatically perform a reset operation to force a restart of the main control unit. Through this mechanism, the system can automatically recover from the fault without human intervention, enhancing the operational stability and reliability of the positioning module in the complex electromagnetic environment of power operation sites and avoiding long-term failure of the positioning function due to system crashes.

[0043] Another aspect of the present invention provides a power consumption control method, which is implemented based on the low-power portable positioning module of Beidou IoT according to any of the above claims, comprising: the Beidou positioning module determining the current geographical location of the positioning module, so that the main control module generates location data of the application device based on the current geographical location; using an accelerometer integrated in the main control unit to sense the movement state of the application device, so that the main control unit calculates the motion intensity of the application device based on the movement state and using a sliding window model and Kalman filter algorithm, and linearly maps the motion intensity to a reporting interval of a target time; the main control unit controls the IoT communication module to transmit the location data to the user management platform based on the reporting interval; when the battery power detected by the power management unit is lower than a preset threshold, the reporting interval is extended; when the application device is stationary, the reporting interval is fixed to a preset time interval.

[0044] The power consumption control method provided by this invention involves the main control unit performing system initialization, reading pre-stored configuration parameters from the built-in FLASH memory, and configuring each functional module. After initialization, the BeiDou positioning module begins searching for BeiDou satellite signals. After successfully capturing and locking onto a satellite, it performs positioning calculations, generating location data containing information such as latitude, longitude, altitude, speed, and time. This location data is then transmitted to the main control unit in real time via a serial communication interface. Simultaneously, the accelerometer integrated into the main control unit continuously collects the device's three-axis acceleration data to monitor the device's motion status in real time. An adaptive algorithm is used to comprehensively analyze the motion data and real-time battery power information monitored by the power management unit to intelligently calculate the optimal reporting interval. For example, when the device is moving rapidly, the algorithm shortens the reporting interval to ensure real-time location updates; when the device is stationary or has low battery power, the reporting interval is extended to save power. After determining the reporting timing, the main control unit packages the current positioning data, device status, and battery information into a communication data packet and hands it over to the IoT communication module for processing. Based on the current network signal quality, 4G is automatically selected. In Cat.1 or NB-IoT communication mode, data packets are securely and reliably transmitted to a remote IoT platform via protocols such as MQTT. Maintenance and management personnel can view the location information, movement trajectory, and status of all deployed positioning modules in real time through the user management platform, achieving centralized and visual management of tools. The management platform also supports remote command issuance, allowing for remote configuration and updates of parameters such as module reporting frequency and operating mode. Throughout the entire working cycle, the power management unit continuously monitors the battery's charging and discharging status and remaining power, and collaborates with the main control unit to execute multiple low-power strategies such as dynamic shutdown, frequency adjustment, and deep sleep. Through the coordinated work of various functional units, a perfect combination of high-precision positioning, reliable communication, and ultra-low power consumption is successfully achieved, ensuring that the module can operate continuously for up to 90 days in a passive outdoor environment, providing solid technical support for critical operations such as power emergency repairs.

[0045] The above method combines motion sensing with power monitoring to achieve an intelligent adaptive energy-saving mode. Instead of passively consuming power, it actively adjusts the working mode dynamically according to the actual status of the equipment and energy reserves. This not only significantly reduces power consumption, but more importantly, it achieves the best balance between energy saving and performance, ensuring the long-term reliable operation of the equipment in critical tasks and producing unexpected technical effects.

[0046] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
