[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Combination Figures 1 to 3 This utility model provides a robust network system for online monitoring of transmission lines in signal-free areas, including a data acquisition module, a main control module, a communication module, a power supply module, and a background control and monitoring module. The data acquisition module includes a line sensor monitoring unit and a line video monitoring unit. The line sensor monitoring units are distributed along the transmission line and connected to the main control module, collecting and transmitting transmission line operating environment data and status data to the main control module. The line video monitoring units are installed on the transmission line towers and connected to the main control module, collecting and transmitting video information of the transmission line to the main control module. The main control module is connected to the communication module, which in turn is connected to the background control and monitoring module. The main control module receives and processes the transmission line operating environment data, status data, and video information, and transmits these data to the background control and monitoring module via the communication module. The power supply module includes a generator unit, a power control unit, and a battery unit, which are connected sequentially to the power control unit and battery unit. The background control and monitoring module receives the transmission line operating environment data, status data, and video information and generates an operating status report.

[0028] Specifically, line sensor monitoring units are distributed along the transmission lines, such as on the towers. These units incorporate various sensors, including temperature, humidity, tension, icing thickness, and tower tilt sensors. These sensors continuously monitor the physical quantities related to the transmission line's operating environment and its own status, converting them into electrical or digital signals. The data is then transmitted to the main control module via wired or wireless connections. Line video monitoring units are installed at critical locations along the transmission lines, such as areas with concentrated towers, areas where multiple transmission lines intersect, and key fire prevention areas. Equipped with high-definition cameras, these units capture real-time video of the transmission lines. The video images captured by the cameras are transmitted to the main control module. Their coverage includes the line's appearance and surrounding environment, providing a clear view of whether foreign objects are attached to the line, whether trees are growing close to the line, and other visual monitoring information for maintenance personnel. After collecting operating environment data, status data, and video information of the transmission line, the main control module transmits them to the background control and monitoring module via the communication module. The background control and monitoring module generates an operating status report based on the received data and information. It also categorizes and stores the received data according to specific formats and rules, establishing a complete transmission line operating data archive. This provides a data foundation for subsequent data processing, analysis, and querying. Through long-term data accumulation and trend analysis, potential faults can be predicted in advance, providing decision support for maintenance personnel. This enables a comprehensive assessment of the transmission line's operating status, improving the efficiency and intelligence of transmission line maintenance while reducing maintenance costs and manpower. Furthermore, the power module is configured with a generator unit connected sequentially to the power control unit and battery unit. The generator unit charges the battery unit, and the power control unit detects the battery's charge level and controls its charging and discharging accordingly. This configuration enables the system to be self-powered, ensuring continuous and stable operation. In the preferred embodiment, the power generation unit uses a combination of solar panels and wind turbines to generate electricity, using two renewable energy sources to charge the battery modules. This reduces operating costs and dependence on traditional energy sources, exhibiting environmentally friendly and sustainable characteristics. In remote areas, even without grid connection, the normal operation of the grid-connected equipment can be ensured by relying on solar and wind power, improving the feasibility and adaptability of online monitoring of transmission lines in different geographical environments.

[0029] Combination Figure 5In a preferred embodiment, the power control unit includes an MPPT control subunit and a BMS control subunit. The power generation unit is connected to the MPPT control subunit, which is also connected to the battery unit. The MPPT control subunit is used to allocate the electrical energy flow from the power generation unit to the battery unit. The BMS control subunit is connected to both the MPPT control subunit and the battery unit, and is used to monitor the voltage, current, and temperature of the battery unit and transmit this information to the MPPT control subunit. Specifically, the BMS control subunit acquires real-time information from the battery unit, and the MPPT control subunit adjusts and controls the electrical energy flow from the power generation unit based on this real-time information. Through precise control and management, the battery is prevented from operating under harsh conditions, overcharging or over-discharging is prevented, the battery status is monitored in real time, and safety issues caused by battery failure are prevented, ensuring battery safety and lifespan.

[0030] In a preferred embodiment, the power module further includes a battery output voltage regulator unit, which is connected to both the MPPT control subunit and the battery unit, and is used to regulate the voltage of the electrical energy output from the battery unit. The battery output voltage regulator unit provides a stable operating voltage for the devices in the system, preventing damage or malfunction due to voltage fluctuations.

[0031] In a preferred embodiment, the battery unit comprises multiple batteries. The BMS control subunit detects the power levels of these batteries and transmits this information to the MPPT control subunit. The MPPT control subunit then controls the charging and discharging of the batteries based on this power level information. The multiple battery configuration allows the BMS and MPPT control subunits to work together to switch to other functioning batteries in the event of a battery failure, ensuring continuous and stable system operation. Simultaneously, the BMS control subunit can also acquire the power levels of the multiple batteries. The MPPT control subunit uses this information to control the power flow of the power generation unit, ensuring maximum power output and improving energy utilization. The specific connection method between the battery unit and the devices requiring power in the system is not limited. Optionally, Power over Ethernet (PoE) can be used to transmit power and data through the same network cable, reducing wiring complexity and enabling centralized management and control of devices requiring power. Furthermore, for applications requiring higher voltages, a boost communication interface can be installed in the battery unit to meet the needs of different devices in the system.

[0032] Combination Figure 6 and Figure 7In a preferred embodiment, the main control module has multiple single RJ45 network ports, each connected to a PoE avionics port. One of the single RJ45 network ports is connected to a network switch chip, which in turn connects to each PoE avionics port. The network switch chip is used to switch the external communication path of the main control module. The main control module also has multiple spare RJ45 network ports, each connected to a mechanical control unit. The mechanical control unit is connected to a spare RJ45 network port and is used to switch the external communication path of the main control module. This setup enables coordinated hardware and software control of the main control module's communication. Specifically, one single RJ45 network port connects to a gigabit high-speed switch chip, which then connects to various external PoE ports. Each PoE port also communicates with each single RJ45 network port. When the main control unit detects an abnormality in the external PoE port communication via the network switch chip, and multiple restarts and reconnections fail, the main control unit automatically switches to the corresponding single-port communication network port through its internal control program, cutting off communication with the corresponding port under the switch. This establishes stable communication between the main control unit and the abnormal PoE port. This close coordination between dual-communication hardware control and software control algorithms significantly improves the communication stability between the main control unit and external acquisition devices. Furthermore, a spare RJ45 network port can be set on the main control module, for example, two RJ45 network ports. Multiple PoE connectors are connected to the mechanical control unit, which in turn connects to the spare RJ45 network port. When a connector experiences a communication failure and cannot connect to the device, the main control unit attempts to reconnect. If multiple attempts fail, the main control unit issues a mechanical action command. Upon receiving the command, the unit will insert the faulty connector into the spare RJ45 communication port. The number of spare communication ports can be expanded according to the actual peripheral devices connected. This method of internal mechanical switching of connection cables is traditional, easy to operate, and will greatly improve the stability of external device connections.

[0033] Combination Figure 1 In a preferred embodiment, the system also includes a co-control MCU, which is connected to the main control module. By coordinating control of the system by the main control module and the co-control MCU, overall system power consumption is reduced, battery life is extended, and the device can operate more economically and efficiently while maintaining its monitoring functions. This is particularly suitable for scenarios with limited power supply, such as areas without signal coverage.

[0034] In a preferred embodiment, the system further includes a voltage conversion module connected to the battery unit via the main control module. This module adjusts the output voltage of the battery unit. Specifically, the main control module controls the voltage conversion module to adjust the output voltage of the battery unit based on the operating voltage of each device in the system, ensuring stable and normal operation of each unit. Simultaneously, it can also adjust the voltage according to system requirements, adapting to voltage demands under different operating conditions. This ensures that all electronic components within the system operate under stable voltage, improving the overall reliability and stability of the system and reducing the risk of equipment failure due to voltage fluctuations.

[0035] Combination Figure 4 In a preferred embodiment, the communication module includes a first wireless bridge communication unit and a second wireless bridge communication unit; the second wireless bridge communication unit and the first wireless bridge communication unit serve as backups for each other. Specifically, in areas with no signal or weak communication signals, the first and second wireless bridge communication units create a data transmission channel to transmit the data collected by the data acquisition module to the monitoring center or other receiving devices with signals, ensuring that data can be transmitted across areas without signals and achieving remote monitoring. By setting up two wireless bridge communication units, if one wireless bridge communication unit fails (e.g., hardware damage, strong interference), the other can immediately take over, ensuring uninterrupted data transmission. For example, in situations where severe weather (e.g., heavy rain, strong winds) may affect wireless communication, even if the signal of one wireless bridge communication unit is interfered with or its equipment is damaged, the other can still maintain data transmission, ensuring continuous communication between the entire monitoring system and the backend, improving the overall reliability and stability of the system. Furthermore, through reasonable configuration and division of labor, the efficiency and capability of data transmission can be improved. For example, when the data volume is large (such as transmitting multiple sensor data and high-definition video images at the same time), data of different types or sources can be distributed to different wireless bridge communication units for transmission, avoiding congestion on a single communication link, achieving load balancing, thereby improving the data transmission speed and capacity of the entire system, ensuring that monitoring data can be transmitted to the background control and monitoring module in a timely and complete manner, and providing strong support for the real-time monitoring and analysis of power transmission lines.

[0036] In a preferred embodiment, the communication module further includes a wireless WiFi debugging unit, a 4G module reserved communication unit, and a point-to-multipoint communication unit. The wireless WiFi debugging unit connects to the main control module and provides a debugging interface during system debugging. The 4G module reserved communication unit connects the main control module and the backend control and monitoring module, providing a data transmission channel in areas with 4G signal coverage. The point-to-multipoint communication unit connects to the main control module, enabling data communication between one main control module and multiple data acquisition modules and multiple power supply modules. Specifically, debugging personnel can connect to the system via the wireless WiFi debugging unit to easily perform operations such as setting equipment parameters, monitoring status, and upgrading software, without the need for complex wired connections. In areas with 4G signal coverage, the 4G module reserved communication unit can access the 4G network, providing a high-speed and stable data transmission channel for the system, efficiently transmitting monitoring data from the transmission lines to the backend control and monitoring module for remote monitoring. It can also receive configuration information and control commands from the backend system. This provides multiple communication options for the system in different signal environments, enhancing the adaptability of the device and allowing it to fully leverage the advantages of high-speed transmission and improve monitoring efficiency when 4G signal conditions are available. The point-to-multipoint communication module enables data communication between one master node and multiple slave nodes. Within the system, it facilitates stable networking of main communication equipment between various towers, ensuring effective data exchange and collaborative work between data acquisition modules at different locations to jointly complete the comprehensive monitoring of transmission lines. This effectively integrates dispersed monitoring resources, improves networking efficiency, and reduces wiring costs and complexity.
