[0041] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0042] Combination Figure 1 and Figure 2 The present invention provides a control method for a robust networking system for online monitoring of power transmission lines in a no-signal area, comprising:

[0043] Collecting transmission line monitoring data. Specifically, by deploying various sensors around the transmission line, such as environmental sensors and cameras, and using the sensing and collection functions of the sensors, the physical quantities, images and other information of the surrounding environment are obtained. This provides basic data for subsequent analysis and judgment of the surrounding conditions of the transmission line.

[0044] Obtain the battery status data of the power generation unit in the system and the power consumption data of the system. Specifically, monitor the battery voltage, current, power and other parameters in real time to determine the battery status and understand the energy supply of the system, so as to reasonably arrange data upload and other operations; according to the operating status of the system, obtain the power consumption of the system. The specific method of power consumption collection is not limited here. It can be that the system is equipped with a power monitoring module, or the power consumption in each operating state is pre-measured according to the different operating states of the system and stored in the system.

[0045] comparing the power consumption data with the battery status data;

[0046] According to the comparison results, the transmission line monitoring data upload mode is selected, and the transmission line monitoring data is uploaded to the system background. Specifically, according to the comparison results of the power consumption data and the battery status data, different data upload modes are selected according to the preset logical rules, and the data is transmitted to the system background through the wireless or wired communication module. Under different energy supply conditions, the data upload mode is reasonably selected to balance the data transmission demand and energy consumption.

[0047] Through this control method, we can fully grasp the environmental changes and potential threats around the transmission line, and provide data support to ensure the safe operation of the transmission line. It can avoid abnormal system operation due to insufficient energy and improve the stability and reliability of system operation. While ensuring data transmission, it can optimize energy utilization and extend the system working time.

[0048] In a preferred case, the battery status data includes power generation data, and the transmission line monitoring data uploading mode is selected according to the comparison result, including:

[0049] When the power generation is greater than or equal to the power consumption, the power generation unit directly supplies power to the system and starts the full data upload mode. Specifically, when the power comparison result meets the conditions, the power generation unit directly supplies power to the system through the circuit, and the system starts the corresponding communication module to upload various data according to the setting of the full data upload mode. When the energy is sufficient, all kinds of monitoring data are fully uploaded to achieve comprehensive monitoring of the transmission line. In the preferred case, the full data upload mode includes: uploading environmental information data, real-time video data and image data. The collection method of each data is not limited here. Optionally, the environmental information data can be a temperature and humidity sensor, a wind speed sensor, an air pressure sensor and other environmental sensors to sense the physical quantities of the surrounding environment such as temperature and humidity, wind speed, and air pressure and convert them into processable data such as electrical signals; real-time video data can be installed by using a camera, using an image sensor to convert the optical signal into an electrical signal, and then processed by encoding and other processing to form a video stream. Intuitively obtain real-time dynamic pictures around the transmission line; image data can be set to take pictures at a certain time interval by setting the camera, and obtain image data through the image sensor. Record the state of the surrounding area of ​​the transmission line at different times in the form of pictures. This control method helps analyze the impact of environmental factors on transmission lines and prevents failures caused by environmental changes in advance. It can detect abnormal conditions such as external force damage in a timely manner, improving the timeliness and accuracy of monitoring.

[0050] When the power generation is less than the power consumption, the battery unit supplies power to the system and starts the normal data upload mode. Specifically, when the power comparison result does not meet the conditions, the battery unit supplies power to the system through the circuit, and the system only uploads part of the data according to the normal data upload mode settings. When energy is insufficient, the data transmission volume is reduced, energy consumption is reduced, and key data transmission is prioritized. In the preferred case, the normal data upload mode includes: uploading environmental information data and image data.

[0051] Through this control method, when the power generation is sufficient and the battery is sufficient, the full data upload mode is turned on to improve the comprehensiveness and accuracy of monitoring, which helps to discover various potential problems in a timely manner. When the power generation is low, the regular data upload mode is turned on to extend the battery life and maintain the basic monitoring function of the system under limited energy conditions.

[0052] In a preferred case, the battery status data also includes the battery power. When the power generation is less than the power consumption, the transmission line monitoring data upload mode is selected according to the comparison result, and further includes:

[0053] When the battery power is greater than or equal to 30%, the normal data upload mode is turned on. Specifically, the battery power is obtained through the battery power monitoring circuit, and when the power meets the conditions, the system switches to the normal data upload mode. When the battery power is relatively sufficient but the energy supply is still insufficient, a relatively moderate data upload mode is adopted.

[0054] When the battery power is less than 30%, the basic data upload mode is turned on. Specifically, when the battery power monitoring circuit determines that the power is less than 30%, the system switches to the basic data upload mode and only uploads the necessary image data. When the battery power is seriously insufficient, energy consumption is reduced to the greatest extent to ensure that the system can continue to operate and transmit key data. In a preferred case, the basic data upload mode includes uploading image data at intervals.

[0055] Through this control method, the appropriate data upload mode is selected according to the remaining battery power. While ensuring a certain amount of data transmission, energy consumption is reasonably controlled, the system's working time in a low-power state is extended, and the transmission of key information is guaranteed.

[0056] Combination Figure 3 In a preferred embodiment, the control method further comprises:

[0057] Set the working mode of the system main control module according to different time periods. Specifically, obtain time information, and set the working mode of the main control module according to the correspondence between the preset time period and the working mode. According to the monitoring requirements of the transmission line in different time periods, reasonably arrange the working mode of the main control module.

[0058] Switch the working mode of the system main control module according to the time period. Specifically, monitor the time in real time. When the time reaches the preset switching point, the system switches the working mode of the main control module according to the set logic. Automatic switching of the working mode of the main control module is realized to meet the monitoring needs of different time periods.

[0059] According to the working mode of the main control module, the operating status of the system's external devices is controlled. Specifically, the main control module sends control signals to the external devices through the control circuit according to its own working mode to control the operation or sleep of the devices. Further optimize the system energy consumption and reasonably control the external devices in different working modes.

[0060] Through this control method, the energy consumption of the system during the monitoring low period is reduced, the energy utilization efficiency is improved, and the service life of the system is extended. At the same time, the working mode of the main control module is automatically switched to improve the automation of the system and reduce manual intervention. Controlling the operating status of external equipment can reduce overall energy consumption and extend the system operation time.

[0061] In a preferred case, setting the working mode of the system main control module according to different time periods includes:

[0062] When the current time period is the peak period of system monitoring, the main control module enters the normal working mode. Specifically, if the current time is in the preset peak period, the system controls the main control module to enter the normal working mode so that it can process various data and instructions. In the time period with high monitoring demand, the main control module can work efficiently to meet the data processing and equipment control needs.

[0063] When the current time period is the low period of system monitoring, the main control module enters the sleep mode. Specifically, if the current time is judged to be in the low period, the system controls the main control module to enter the sleep mode to reduce its power consumption. In the period of low monitoring demand, the energy consumption of the main control module is reduced.

[0064] It should be noted that the specific time periods of peak and trough periods are not limited here. The peak and trough periods can be determined based on the long-term transmission power statistics of the transmission line, or they can be determined based on the daily electricity consumption patterns. For example, daytime to dusk is the peak period of electricity consumption in the area, and the system monitoring is also in the peak period of operation. Late night to early morning is the trough period of electricity consumption in the area, and the system monitoring is also in the trough period of operation. Through such a control method, during the peak period, the probability of failure of the transmission line is high, and the transmission line is fully and timely monitored. During the trough period, the load of the transmission line is small and the probability of failure is low. The main control module enters the sleep mode to save energy and extend the overall operation time of the system.

[0065] In a preferred case, the working mode of the main control module is switched according to the time period, and the operating state of the external device of the system is controlled according to the working mode of the main control module, including:

[0066] When the system monitoring changes from a low period to a peak period, the battery unit first powers on the system's cooperative MCU, and the cooperative MCU powers on the main control module. The main control module switches from sleep mode to normal working mode, and connects to external devices for normal operation. Specifically, when the time change is detected, the system controls the battery unit to power the cooperative MCU, and the cooperative MCU then powers the main control module. The main control module switches modes and controls the operation of external devices. The main control module and external devices can be smoothly switched between different monitoring periods to ensure the normal operation of the system.

[0067] When the system monitors that the peak period changes to the valley period, the coordinated MCU disconnects the power supply of the main control module, the main control module switches from the normal working mode to the sleep working mode, and the external device enters the sleep state. Specifically, when the time change is detected, the coordinated MCU disconnects the power supply of the main control module according to the system instruction, the main control module switches the mode and controls the external device to enter the sleep state. Reduce the system energy consumption in time during the monitoring valley period.

[0068] In a preferred embodiment, the control method further comprises:

[0069] Determine the communication status of the system's main control module. Specifically, through the communication monitoring circuit or software algorithm, monitor the signal strength, bit error rate and other parameters during the communication process of the main control module to determine whether the communication is normal. Timely discovery of communication anomalies provides a basis for taking countermeasures.

[0070] When the communication is abnormal, switch the communication mode of the main control module. Specifically, when the communication abnormality is detected, the system changes the communication frequency band, protocol or antenna of the main control module through software, hardware or mechanical means according to the preset switching logic. When the communication is abnormal, try to restore normal communication to ensure data transmission.

[0071] Through this control method, the stability and reliability of system data transmission are guaranteed, and the adaptability of the system in complex communication environments is improved.

[0072] In a preferred case, switching the communication mode of the main control module includes:

[0073] Switch the communication mode through the control instructions of the main control module. Specifically, through the control instructions of the main control module, the parameters of the hardware circuit are controlled by the software transmission instructions, such as switching the communication frequency band, changing the modulation and demodulation mode, etc., to achieve the switching of the communication mode. Quickly adjust the communication parameters at the software level and try to restore communication.

[0074] Switch the communication mode through the mechanical control unit. Specifically, change the communication antenna or other hardware connection through the mechanical control unit to change the communication mode. When the software and hardware cannot solve the problem, physically change the communication hardware configuration to restore communication.

[0075] In a strong networking system for online monitoring of power transmission lines in a signal-free area, the main control module of the system has an extended RJ45 network port, one of which is connected to a gigabit high-speed switch chip, and the switch chip is then connected to each external POE air socket, and each air socket is also directly connected to each single RJ45 network port; when the main control module detects that the external POE air socket has abnormal communication through the network port switch chip, and multiple restarts and reconnections are unsuccessful, the main control module automatically runs the control program, switches to the corresponding single-port communication network port, and cuts off the communication of the corresponding network port under the switch, thereby establishing a stable communication between the main control module and the abnormal air socket. In addition, the extended RJ45 network ports in the main control module are each connected to the external air socket in a single document, and the external air socket is mechanically connected to the mechanical control unit installed inside; when a certain air socket has a communication abnormality and cannot connect to the device, the main control module first tries to connect. After multiple connection failures, the main control module sends a mechanical action instruction, and the mechanical control unit executes the abnormal air socket connection line after receiving the instruction to insert the spare RJ45 communication network port. This realizes software and hardware coordination control and mechanical manipulation control. Through these two control strategies, the communication stability between the main control module and data acquisition and transmission is improved.
