Description

Technical Field

[0001] The present application relates to the technical field of power transmission line monitoring, and in particular to a method, system, electronic device and storage medium for monitoring power transmission line sway based on Beidou positioning. Background Art

[0002] Transmission lines are a key component of power grid operation. Transmission line conductor dancing, wind deviation, and breeze vibration have long been important factors affecting the safe operation of power grid transmission lines, which can cause transmission line tripping, partial bolts falling off of tower crossarms, and damage to tower crossarms, jumpers, insulators, and hardware, making the power grid operation situation extremely severe.

[0003] At present, the monitoring of the dancing, wind deviation and breeze vibration of the transmission line conductor mainly adopts Beidou positioning technology. Specifically, the Beidou positioning chip module is installed in the position monitoring terminal, and then the position monitoring terminal is installed on the transmission line conductor. The Beidou positioning chip module obtains the current position information through the Beidou satellite, and then sends the obtained current position information to the position monitoring platform. The position monitoring platform establishes a dynamic model of the transmission line conductor through the position information of the transmission line conductor received multiple times, and then realizes the monitoring of the dancing, wind deviation and breeze vibration of the transmission line conductor based on the dynamic model.

[0004] However, high-precision positioning using the Beidou positioning chip module still has centimeter-level or millimeter-level errors. This will cause the dynamic model of the transmission line conductor to deviate from the actual transmission line conductor situation, thereby reducing the accuracy of monitoring the transmission line conductor's dancing, wind deviation, and breeze vibration. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a transmission line dancing monitoring method, system, electronic device and storage medium based on Beidou positioning, so as to improve the accuracy of monitoring the dancing, wind deviation and breeze vibration of transmission line conductors.

[0006] In order to solve the above technical problems, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of the present application provides a method for monitoring the vibration of a transmission line based on Beidou positioning, the method being applied to a monitoring system, the monitoring system comprising a monitoring background and a position monitoring terminal, the position monitoring terminal being installed on a transmission line, the position monitoring terminal comprising a Beidou positioning chip module and a mobile sensor, the Beidou positioning chip module being used to obtain Beidou positioning information, the mobile sensor being used to perform displacement monitoring; the method comprising: the Beidou positioning chip module obtaining the position information of the transmission line at different times, and sending the position information to the monitoring background; the mobile sensor obtaining the movement information between adjacent moments of the transmission line at different times, and sending the movement information to the monitoring background; the monitoring background determining whether the transmission line generates vibration, wind deviation, and breeze vibration based on the position information and the movement information.

[0008] Compared with the prior art, the transmission line dancing monitoring method based on Beidou positioning provided in the first aspect of the present application, in the process of monitoring the transmission line dancing, wind deviation and breeze vibration based on Beidou positioning, combined with the movement information of the transmission line obtained by the sensor, can make the judgment of the transmission line dancing, wind deviation and breeze vibration more accurate, and improve the accuracy of monitoring the transmission line conductor dancing, wind deviation and breeze vibration.

[0009] In some modified implementations of the first aspect of the present application, the determining whether the transmission line generates dancing, wind deviation, and breeze vibration based on the position information and the movement information includes: generating a first monitoring result of whether the transmission line generates dancing, wind deviation, and breeze vibration based on the position information; generating a second monitoring result of whether the transmission line generates dancing, wind deviation, and breeze vibration based on the movement information; determining whether the first monitoring result is the same as the second monitoring result; if so, determining whether the transmission line generates dancing, wind deviation, and breeze vibration based on the first monitoring result or the second monitoring result; if not, determining whether the transmission line generates dancing, wind deviation, and breeze vibration based on the wind force level of the environment in which the transmission line is located, the first monitoring result, and the second monitoring result.

[0010] Only when the monitoring results based on Beidou positioning and sensors are completely consistent, the results of whether there is dancing, wind deviation and breeze vibration in the same monitoring results will be used as the final monitoring results of the transmission line. When there are inconsistencies in the monitoring results based on Beidou positioning and sensors, the wind force level of the environment in which the transmission line is located will be combined to further improve the accuracy of monitoring the dancing, wind deviation and breeze vibration of the transmission line conductors.

[0011] In some changed implementation modes of the first aspect of the present application, the second monitoring result of whether the transmission line generates dancing, wind deviation and breeze vibration based on the movement information includes: comparing the movement information with the transmission line dancing threshold chain, and generating the dancing monitoring result of the transmission line according to the comparison result; comparing the movement information with the transmission line wind deviation threshold chain, and generating the wind deviation monitoring result of the transmission line according to the comparison result; comparing the movement information with the transmission line breeze vibration threshold chain, and generating the breeze vibration monitoring result of the transmission line according to the comparison result; based on the dancing monitoring result, the wind deviation monitoring result and the breeze vibration monitoring result, a second monitoring result of whether the transmission line generates dancing, wind deviation and breeze vibration is generated.

[0012] In the sensor-based monitoring of the dancing, wind deviation and breeze vibration of the transmission line, after obtaining the movement information of the line monitored by the sensor, it is no longer calculated through the model, but simply compared with various threshold chains such as dancing. This can speed up the monitoring calculation of the transmission line movement and improve the efficiency of transmission line monitoring.

[0013] In some modified implementations of the first aspect of the present application, the determining whether the transmission line generates dancing, wind deviation and breeze vibration based on the wind force level of the environment in which the transmission line is located, the first monitoring result and the second monitoring result includes: judging whether the first monitoring result is completely different from the second monitoring result; if so, determining the target dynamics from the dancing, wind deviation and breeze vibration based on the wind force level of the environment in which the transmission line is located, and using the target dynamics as the final monitoring result of the transmission line; if not, determining the same monitoring result from the first monitoring result and the second monitoring result, and using the same monitoring result as the final monitoring result of the transmission line.

[0014] In the case where the monitoring results based on Beidou positioning and sensors are completely inconsistent, whether the transmission line will produce dancing, wind deviation and breeze vibration can be determined directly based on the wind force level of the environment in which the transmission line is located, so as to achieve efficient and accurate monitoring. And in the case where the monitoring results based on Beidou positioning and sensors are partially consistent, the same monitoring results are used as the monitoring results of the transmission line to ensure the accuracy of monitoring.

[0015] In some modified implementations of the first aspect of the present application, the position monitoring terminal also includes a wire current transformer (CT) power supply module, a solar power supply module and a controller, and the Beidou positioning chip module and the mobile sensor use the power provided by the solar power supply module by default; the method also includes: the controller determines whether the remaining power of the solar power supply module is less than the preset power; if so, controls the wire CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor; if not, controls the solar power supply module to provide power to the Beidou positioning chip module and the mobile sensor.

[0016] During the monitoring process, solar energy is used by default. When there is insufficient solar energy, the conductor CT is used to draw electricity. While ensuring that there is continuous electricity use during the monitoring process, the consumption of electricity on the transmission line is minimized to ensure the normal operation of the transmission line.

[0017] In some changed implementation modes of the first aspect of the present application, the controlling of the conductor CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor includes: determining the importance of the transmission line in the transmission network; judging whether the importance is greater than a preset degree; if so, controlling the conductor CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor until the position monitoring terminal stops being used; if not, controlling the conductor CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor before the solar power supply module is fully charged.

[0018] After switching to the wire CT power supply mode, if the transmission line is more important, the wire CT power supply will continue to be used to power the monitoring terminal, avoiding the terminal power mode from repeatedly switching between solar energy and wire CT power supply, reducing the number of repeated starts and stops of CT power supply on important lines, and ensuring the stable operation of important lines. And if the importance of the transmission line is average, after the solar energy is full, continue to use solar energy to power the monitoring, further reducing the consumption of power on the transmission line and ensuring the normal operation of the transmission line.

[0019] In some modified implementations of the first aspect of the present application, an odd number of position monitoring terminals are installed on the transmission line, each position monitoring terminal is installed with a locator and a Beidou differential correction module, and the locator can obtain the installation position of each position monitoring terminal in the transmission line; before sending the position information to the monitoring background, the method also includes: the locator determines the target monitoring terminal installed in the middle position among the odd number of position monitoring terminals; the Beidou differential correction module uses the Beidou differential positioning technology to correct the position information obtained by the Beidou positioning chip module in the target monitoring terminal to obtain the positioning information; The method further comprises: the Beidou differential correction module sends the positioning information with the importance mark added to the monitoring background; the Beidou positioning chip module of the other monitoring terminals sends the acquired position information to the monitoring background, and the other monitoring terminals are the monitoring terminals other than the target monitoring terminal among the odd number of position monitoring terminals; after the position information is sent to the monitoring background, the method further comprises: the monitoring background determines the movement state of the transmission line based on the information sent by each position monitoring terminal, so as to judge whether the transmission line generates dancing, wind deviation and breeze vibration in combination with the movement information.

[0020] When performing differential correction on Beidou positioning, only the position information obtained by a terminal in the middle of the transmission line is corrected. This can not only achieve the purpose of positioning correction, but also avoid correcting more position information in the same line. It can improve the efficiency of Beidou positioning without causing serious deviation in positioning, and thus improve the monitoring efficiency without having a significant impact on the accuracy of monitoring.

[0021] The second aspect of the present application provides a transmission line waving monitoring system based on Beidou positioning, the system comprising a monitoring background and a position monitoring terminal, the position monitoring terminal being installed on the transmission line, the position monitoring terminal comprising a Beidou positioning chip module and a mobile sensor, the Beidou positioning chip module being used to obtain Beidou positioning information, the mobile sensor being used to perform displacement monitoring; when the system is running: the Beidou positioning chip module is used to obtain the position information of the transmission line at different times under the current position, and send the position information to the monitoring background; the mobile sensor is used to obtain the movement information between adjacent moments in the different moments under the current position of the transmission line, and send the movement information to the monitoring background; the monitoring background is used to determine whether the transmission line generates waving, wind deviation and breeze vibration based on the position information and the movement information.

[0022] The third aspect of the present application provides an electronic device, comprising: a processor, a memory, and a bus; wherein the processor and the memory communicate with each other via the bus; and the processor is used to call program instructions in the memory to execute the method in the first aspect.

[0023] A fourth aspect of the present application provides a computer-readable storage medium, the storage medium comprising: a stored program; wherein, when the program is executed, the device where the storage medium is located is controlled to execute the method in the first aspect.

[0024] The transmission line dancing monitoring system based on Beidou positioning provided in the second aspect of this application, the electronic device provided in the third aspect, and the computer-readable storage medium provided in the fourth aspect have the same or similar beneficial effects as the transmission line dancing monitoring method based on Beidou positioning provided in the first aspect.

[0033] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0035] At present, the monitoring of power transmission line sway, wind deviation and breeze vibration mainly relies on Beidou positioning. However, Beidou positioning still has millimeter-level or even centimeter-level errors, which reduces the accuracy of monitoring of power transmission line sway, wind deviation and breeze vibration.

[0036] In view of this, the embodiments of the present application provide a transmission line sway monitoring method, system, electronic device and storage medium based on Beidou positioning. In the monitoring of the sway, wind deviation and breeze vibration of the transmission line, not only does Beidou positioning determine the position of the transmission line at different times, thereby determining the dynamics of the transmission line, but also sensors are used to monitor the dynamics of the transmission line. The combination of the two can achieve accurate monitoring of the sway, wind deviation and breeze vibration of the transmission line.

[0037] First, the overall architecture of the transmission line dancing monitoring method based on Beidou positioning provided in the embodiment of the present application is described.

[0038] Figure 1 The overall architecture of the transmission line galloping monitoring based on Beidou positioning in the embodiment of the present application is shown as follows Figure 1 , see Figure 1 As shown, the architecture may include: a power transmission line 11, a monitoring system 12 and a BeiDou satellite 13. The monitoring system 12 may include: a monitoring background 121 and a location monitoring terminal 122.

[0039] During the initial installation, the location monitoring terminal 122 is installed on the power transmission line 11. The location monitoring terminal 122 may include a Beidou positioning chip module 122a and a mobile sensor 122b. The Beidou positioning chip module 122a is used to obtain Beidou positioning information, and the mobile sensor 122b is used to perform displacement monitoring.

[0040] In specific monitoring, the Beidou positioning chip module 122a obtains the location information of the transmission line 11 at different times through the Beidou satellite 13, and immediately sends the location information to the monitoring background 121 after obtaining the location information at one time. At the same time, the mobile sensor 122b obtains the movement information of the transmission line 11 between adjacent times, and immediately sends the movement information to the monitoring background 121 after obtaining the movement information between two times. The monitoring background 121 can construct the movement of the transmission line 11 at these times based on the location information at multiple times, and can also construct the movement of the transmission line 11 at these times based on the movement information between adjacent times. Combined with the two movement conditions, it is comprehensively determined whether the transmission line 11 produces dancing, wind deviation and breeze vibration.

[0041] Next, the transmission line dancing monitoring method based on Beidou positioning provided in an embodiment of the present application is described in detail.

[0042] Figure 2 The process diagram of the transmission line galloping monitoring method based on Beidou positioning in the embodiment of the present application is as follows Figure 1 , see Figure 2 As shown, the method may include:

[0043] S21: The Beidou positioning chip module obtains the location information of the power transmission line at different times and sends the location information to the monitoring background.

[0044] The transmission line here may refer to a conductor between two adjacent electric poles in the transmission line conductor to be monitored for dancing, wind deviation and breeze vibration.

[0045] A location monitoring terminal is installed on the transmission line. The location monitoring terminal includes a Beidou positioning chip module. Therefore, when obtaining location information, the Beidou positioning chip module obtains its current location information through Beidou satellites, and this location information is regarded as the location information of the transmission line at that moment, thereby achieving fast and accurate acquisition of location information.

[0046] The Beidou positioning chip module can be an existing Beidou positioning terminal or a module for implementing Beidou positioning in an existing Beidou positioning terminal, so as to minimize the space occupied by Beidou positioning components in the position monitoring terminal, reduce the volume of the position monitoring terminal, and thereby reduce the impact of the position monitoring terminal on the transmission line, thereby improving the accuracy of monitoring such as transmission line sway.

[0047] In practical applications, since the transmission line has a certain length, and the Beidou positioning chip module obtains point positions, in order to more accurately determine the location of the transmission line, multiple position monitoring terminals can be configured on the transmission line. The collection of positions monitored by multiple position monitoring terminals can accurately characterize the location of the transmission line.

[0048] After the Beidou positioning chip module obtains the location information of the transmission line at a certain moment, it immediately sends the location information to the monitoring background to avoid confusion caused by multiple location information and improve the accuracy of transmission line positioning. Of course, the Beidou positioning chip module can also send the location information to the monitoring background after continuously obtaining the location information at multiple moments, thereby improving the utilization rate of communication resources for location information transmission, improving the efficiency of location information transmission, and thus improving the efficiency of transmission line positioning.

[0049] When the Beidou positioning chip module sends location information to the monitoring background, the fifth generation mobile communication technology (5G) can be used to achieve efficient transmission of location information. Of course, the fourth generation mobile communication technology (4G) can also be used to achieve the transmission of location information.

[0050] Furthermore, when transmitting the location information, the location information needs to be encrypted to prevent the location information from being maliciously tampered with, thereby improving the accuracy of the transmission line positioning. The specific encryption method can adopt any existing encryption algorithm, or a combination of multiple encryption algorithms.

[0051] S22: The mobile sensor obtains the movement information between adjacent moments in the transmission line at different moments, and sends the movement information to the monitoring background.

[0052] The so-called mobile sensor may refer to a sensor that can sense various dynamics of the power transmission line, such as micro-electromechanical system (MEMS) inertial sensors, displacement sensors, acceleration sensors, tilt sensors, optical cameras, and distributed optical fiber sensors.

[0053] After the Beidou positioning chip module obtains the location information of the transmission line at a certain moment, the mobile sensor is linked with it to obtain the movement information between that moment and the previous moment, such as: how much distance it has moved, how fast it has moved, how much acceleration it has moved, how many degrees it has twisted, etc.

[0054] In the linkage between the Beidou positioning chip module and the mobile sensor, the mobile sensor is electrically connected to the Beidou positioning chip module. Once a new signal is generated in the Beidou positioning chip module, the Beidou positioning chip module will send a monitoring instruction to the mobile sensor, and the mobile sensor will obtain the movement information between this moment and the previous moment based on the monitoring instruction. The Beidou positioning chip module first obtains the position, and then the mobile sensor obtains the movement information, which can ensure the temporal consistency of the position information and the movement information. There is no need to match the position information with the movement information at the time of obtaining the information, thereby improving the efficiency of monitoring such as dancing.

[0055] Of course, the Beidou positioning chip module can obtain location information and the mobile sensor can obtain movement information without linkage, that is, they can obtain them at their own time. After the Beidou positioning chip module and the mobile sensor obtain the corresponding information, they will mark the information with the time of acquisition. After that, the location information of two adjacent moments will correspond to the movement information between the two adjacent moments, so as to monitor the movement and so on.

[0056] When transmitting mobile information, the mobile information also needs to be encrypted. The specific encryption method can be the same as the location information or different from the location information. In this case, it is preferred to select an encryption method different from the location information, so as to avoid the leakage of mobile information after the location information is leaked. If the location information is leaked and the leakage is detected, then the movement and other monitoring can be performed based only on the mobile information to ensure the accuracy of the monitoring.

[0057] S23: The monitoring background determines whether the transmission line is dancing, wind deviation, and breeze vibration based on the location information and movement information.

[0058] After the monitoring background obtains the location information and movement information, on the one hand, it can generate a dynamic model of the transmission line based on the multiple location information obtained, and then compare the detection standards of dancing, wind deviation and breeze vibration to determine whether the transmission line produces dancing, wind deviation and breeze vibration. On the other hand, based on the corresponding movement information obtained, the existing dancing monitoring model, wind deviation monitoring model and breeze vibration monitoring model based on sensor measurement can be used to determine whether the transmission line produces dancing, wind deviation and breeze vibration. Finally, the judgment results of the two aspects are combined to comprehensively determine whether the transmission line produces dancing, wind deviation and breeze vibration.

[0059] In the comprehensive judgment, the judgment results of the two aspects can be integrated into the final judgment result. For example: based on the location information, it is judged that the transmission line is dancing, and based on the movement information, it is judged that the transmission line is dancing, then it is finally judged that the transmission line is dancing. For another example: based on the location information, it is judged that the transmission line is dancing, and based on the movement information, it is judged that the transmission line is wind deflected, then it is finally judged that the transmission line is dancing and wind deflected. For another example: based on the location information, it is judged that the transmission line is dancing, and based on the movement information, it is judged that the transmission line has no dancing, wind deflection, and breeze vibration, then it is finally judged that the transmission line is dancing. In this way, it is possible to avoid detection errors of the Beidou positioning chip module or mobile sensor, and ensure the actual detection of the dancing, wind deflection, and breeze vibration of the transmission line.

[0060] Of course, after the monitoring background obtains the location information and movement information, it can also use the movement information to correct the location information, and then use the corrected location information to generate a dynamic model of the transmission line, and then match the dynamic model with the detection standards of dancing, wind deviation and breeze vibration to determine whether the transmission line produces dancing, wind deviation and breeze vibration. Alternatively, the movement information is corrected using the location information, and then the corrected movement information is substituted into the existing dancing monitoring model, wind deviation monitoring model and breeze vibration monitoring model based on sensor measurement to determine whether the transmission line produces dancing, wind deviation and breeze vibration.

[0061] From the above content, it can be seen that the transmission line dancing monitoring method based on Beidou positioning provided in the embodiment of the present application, in the process of monitoring the transmission line dancing, wind deviation and breeze vibration based on Beidou positioning, combined with the movement information of the transmission line obtained by the sensor, can make the judgment of the transmission line dancing, wind deviation and breeze vibration more accurate, and improve the accuracy of monitoring the transmission line conductor dancing, wind deviation and breeze vibration.

[0062] Furthermore, as a Figure 2 As a refinement and extension of the method shown, an embodiment of the present application also provides a transmission line sway monitoring method based on Beidou positioning.

[0063] Figure 3 The overall architecture of the transmission line galloping monitoring based on Beidou positioning in the embodiment of the present application is shown as follows Figure 2 , see Figure 3 As shown, the architecture may include: a transmission line 11 , a monitoring system 12 and a BeiDou satellite 13 .

[0064] The monitoring system 12 may include: a monitoring background 121 and a location monitoring terminal 122 .

[0065] Among them, the position monitoring terminal 122 may include: a Beidou positioning chip module 122a, a mobile sensor 122b, a wire CT power supply module 122c, a solar power supply module 122d, a controller 122e, a locator 122f and a Beidou differential correction module 122g.

[0066] Here, the Beidou positioning chip module 122a and the mobile sensor 122b use the electric energy provided by the solar power supply module 122d by default. That is to say, only when the solar power supply module 122d can no longer supply power to the Beidou positioning chip module 122a and the mobile sensor 122b, the wire CT power supply module 122c is used to supply power to the Beidou positioning chip module 122a and the mobile sensor 122b. The controller 122e is used to control the switching between the solar power supply module 122d and the wire CT power supply module 122c. Of course, in order to reduce the volume of the position monitoring terminal 122, the solar power supply module 122d and the controller 122e may not be configured, and the wire CT power supply module 122c may be used throughout the process to supply power to all components of the position monitoring terminal 122.

[0067] During initial installation, an odd number of position monitoring terminals 122 are installed on the power transmission line 11 .

[0068] In specific monitoring, the Beidou positioning chip module 122a in each position monitoring terminal 122 obtains position information through the Beidou satellite 13. At the same time, the locator 122f determines the position monitoring terminal 122 located at the most middle position on the transmission line 11. Here, the locator 122f can obtain the installation position of each position monitoring terminal 122 in the transmission line 11. The locator 122f can be a camera, an acoustic wave detector, etc., which determines the specific position or relative position of each position monitoring terminal 122 through image recognition or reflected acoustic waves, thereby determining the position monitoring terminal 122 at the middle position. Then, the locator 122f informs the position monitoring terminal 122 at the middle position to send the acquired position information to the Beidou differential correction module 122g for correction, and the Beidou differential correction module 122g sends the corrected position information carrying the correction mark to the monitoring background 121. After acquiring the location information for a period of time, if the location monitoring terminal 122 at other locations does not receive an instruction to send the location information to the Beidou differential correction module 122g, it directly sends the acquired location information to the monitoring background 121.

[0069] At the same time, the mobile sensor 122 b in each location monitoring terminal 122 obtains the movement information of the power transmission line 11 and sends the movement information to the monitoring background 121 .

[0070] After the monitoring background 121 obtains multiple position information and its corresponding movement information, it can build a dynamic model of the transmission line 11 based on one of the corrected position information and its corresponding movement information, and use the other uncorrected position information and its corresponding movement information as a supplement, to further determine whether the transmission line 11 produces dancing, wind deviation and breeze vibration.

[0071] Figure 4 The process diagram of the transmission line galloping monitoring method based on Beidou positioning in the embodiment of the present application is as follows Figure 2 , see Figure 4 As shown, the method may include:

[0072] S41: The controller determines whether the remaining power of the solar power supply module is less than the preset power. If yes, S42 is executed; if no, S43 is executed.

[0073] During the operation of the location monitoring terminal, the controller needs to determine in real time or at a preset time interval whether the remaining power of the solar power module is less than the preset power. If the remaining power of the solar power module is less, it will not be able to continue to support the operation of the location monitoring terminal, thus affecting the continuity of the monitoring of the transmission line sway, and further affecting the accuracy of the monitoring of the transmission line sway.

[0074] The above-mentioned preset time interval can be fixed or dynamically changing. In the case where the preset time interval is dynamically changing, the more remaining power of the solar power supply module, the longer the preset time interval. Specifically, the remaining power and the preset time interval can be divided into different intervals, and a corresponding relationship can be established.

[0075] The above-mentioned preset power quantity may be a fixed value, such as 1%, 10%, etc. It may also be an estimated quantity based on the normal power supply duration of 1 hour, half a day, etc. of the solar power supply module under the same historical usage environment.

[0076] S42: Control the wire CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor.

[0077] When it is determined that the remaining power of the solar power supply module is less than the preset power, it means that the power stored in the solar power supply module is about to be exhausted. At this time, it is necessary to switch to the wire CT power supply module to supply power to the Beidou positioning chip module and the mobile sensor.

[0078] While the wire CT power module supplies power to the Beidou positioning chip module and mobile sensor, the solar power module no longer outputs electricity and can be charged by solar energy, so the power of the solar power module will continue to increase. When the solar charging module is fully charged or charged to more than half, you can switch to the solar charging module to power the Beidou positioning chip module and mobile sensor, reducing the impact of the location monitoring terminal on the transmission line. Alternatively, continue to use the CT power module to power the Beidou positioning chip module and mobile sensor to ensure the stability of the power supply of the location monitoring terminal, and then ensure the stability of monitoring such as dancing.

[0079] Whether to switch back to the solar power module for power supply can be determined based on the importance of the current transmission line.

[0080] Specifically, the above step S42 may include:

[0081] Step A1: Determine the importance of the transmission line in the transmission network.

[0082] The so-called importance can refer to the distinction between trunk lines and branch lines. When the transmission line is a trunk line, the importance is higher, which can be level one. When the transmission line is a branch line, the importance is lower, which can be level two. The importance can also refer to the size of the city in the area. The larger the city, the higher the importance.

[0083] In the specific determination, it can be determined by the planning map of the transmission line, or by the identification information on the electric poles in the transmission line, or by sending a query to the monitoring background and determining it through the response information fed back by the monitoring background.

[0084] Step A2: Determine whether the importance is greater than a preset degree. If yes, execute step A3; if no, execute step A4.

[0085] Step A3: Control the wire CT power supply module to provide power to the Beidou positioning chip module and the mobile sensor until the location monitoring terminal stops being used.

[0086] In other words, if the transmission line is important, try to avoid switching the power supply module in the location monitoring terminal back and forth. Repeated switching of the power supply module may cause the location monitoring terminal to actively shake, thereby affecting the accuracy of monitoring such as the shaking of the transmission line itself. After that, it is necessary to use the wire CT power supply module to supply power to the Beidou positioning chip module and mobile sensor until the end of this cycle of monitoring. After the next cycle of monitoring begins, jump to the solar power supply module for power supply.

[0087] Step A4: Before the solar power supply module is fully charged, the control wire CT power supply module provides power to the Beidou positioning chip module and the mobile sensor.

[0088] That is to say, if the importance of the transmission line is average, after the power in the solar power supply module is fully charged, it can be switched back to the solar power supply module to continue to power the Beidou positioning chip module and mobile sensor. In this way, the energy consumption of the transmission line can be reduced and the normal power supply of the transmission line can be guaranteed.

[0089] In addition to switching the power supply module, you can also select an object from the temperature sensor and Beidou short message communication module to continue using solar power. If the object is not selected, switch to the wire CT power supply module for power supply.

[0090] In the specific selection, you can choose the object with low historical power consumption and continue to use solar power supply to ensure that the solar power supply module will not be exhausted for a long period of time in the future, ensuring the stable operation of monitoring. You can also directly choose the Beidou short message communication module and continue to use solar power supply, because the Beidou short message communication module generally has low power consumption, which can save the power consumption judgment step, realize the rapid switching of the power supply module, and ensure the continuity of monitoring.

[0091] S43: Control the solar power supply module to provide power to the Beidou positioning chip module and the mobile sensor.

[0092] When it is determined that the remaining power of the solar power supply module is greater than or equal to the preset power, it means that the solar power supply module can continue to power the Beidou positioning chip module and the mobile sensor for a period of time in the future. At this time, the solar power supply module can continue to be used to power the Beidou positioning chip module and the mobile sensor, and once again (when the remaining power is equal to the preset power, it can be judged in time that it is less than the preset power to ensure the accuracy of the power supply module switching time) or after a period of time (to reduce the power consumption caused by the judgment), it is judged whether the remaining power of the solar power supply module is less than the preset power.

[0093] Continue monitoring as long as the Beidou positioning chip module and mobile sensor have power.

[0094] S44: Beidou positioning chip module obtains the location information of the power transmission line at different times.

[0095] One or more location monitoring terminals can be installed in the power transmission line. Each location monitoring terminal is equipped with a Beidou positioning chip module, and each Beidou positioning chip module can obtain the current location information. In other words, the location information of multiple points on the power transmission line can be obtained.

[0096] The location information obtained at this time is still based on the original location information obtained by the Beidou satellite. In order to achieve accurate monitoring such as dancing, these original location information also need to be corrected. However, it will take a lot of time to correct each original location information, and if it is not corrected, it will affect the accuracy of monitoring. In view of this, only part of the location information can be corrected. In this way, the correction time can be shortened, and the accuracy of monitoring will not be reduced due to non-correction, taking into account both the efficiency and accuracy of monitoring.

[0097] When selecting the corrected position information, one or more position information may be randomly selected, or a number of position information may be selected at a preset interval, or the position information obtained by the position monitoring terminal located at the most middle position may be selected (the optimal choice for balancing monitoring efficiency and accuracy). When selecting the position information obtained by the position monitoring terminal at the middle position, it is necessary to ensure that the number of position monitoring terminals in the transmission line is an odd number.

[0098] S45: The locator determines the target monitoring terminal installed at the middle position among the odd-numbered position monitoring terminals.

[0099] Since there are multiple location monitoring terminals in the transmission line, each location monitoring terminal is installed with a locator, that is, there are multiple locators in the transmission line. Therefore, each locator can be used to determine a target monitoring terminal, and then based on the target monitoring terminals determined by each locator, the final target monitoring terminal can be comprehensively determined. Comprehensive determination can be to select the same terminal determined by most locators, or to combine the weights of each locator and the terminals determined by them to select the terminal with the highest proportion. For example: locator 1 has a weight of 20% and determines terminal a, locator 2 has a weight of 30% and determines terminal b, locator 3 has a weight of 10% and determines terminal b, locator 4 has a weight of 40% and determines terminal a, then the proportion of terminal a is 60%, the proportion of terminal b is 40%, and terminal a is finally selected as the target monitoring terminal.

[0100] Alternatively, a locator in the transmission line may be selected to determine the target monitoring terminal. In the selection of the locator, a random selection may be made, a locator not used in the previous round may be selected, or a locator with the highest accuracy in historical determination may be selected.

[0101] For the locator, it can obtain the location information obtained by the Beidou positioning chip module of its own location monitoring terminal, as well as the location information obtained by the Beidou positioning chip modules of other location monitoring terminals, and then combine these location information to determine the target monitoring terminal at the middle position in the transmission line.

[0102] Alternatively, if the locator is a camera or an ultrasonic instrument, the terminal can be identified through the image captured by the camera, or the position of each terminal can be determined through the feedback of the sound waves emitted by the ultrasonic instrument. Then, the relative position of the monitoring terminal at each position can be determined, thereby determining the target monitoring terminal at the middle position in the transmission line.

[0103] After the locator determines the target monitoring terminal, it can send information to the target monitoring terminal, prompting the target monitoring terminal to send the location information to the Beidou differential correction module for correction. Based on the received information, the target monitoring terminal sends the location information to the Beidou differential correction module for correction. Alternatively, the locator sends information to the Beidou differential correction module, prompting it to correct the location information obtained by the target monitoring terminal. Based on the received information, the Beidou differential correction module sends information to the target monitoring terminal to obtain the location information. Based on the received information, the target monitoring terminal sends the location information to the Beidou differential correction module for correction.

[0104] S46: The Beidou differential correction module corrects the location information obtained by the Beidou positioning chip module in the target monitoring terminal using Beidou differential positioning technology to obtain positioning information.

[0105] The Beidou differential positioning technology used here is carrier phase differential (Real Time Kinematics, RTK) technology.

[0106] S47: The Beidou differential correction module sends the positioning information with importance marks added to the monitoring background.

[0107] Since there are multiple location information generated at the same time, and the Beidou differential correction module only corrects one of the location information, it is necessary to carry an identifier in the corrected information so that the monitoring background can know which location information is corrected from the multiple location information, so as to focus on it and improve the accuracy of monitoring.

[0108] When adding an importance mark, you can add it in the header of the information so that the mark can be found quickly, or you can add it in a preset position in the information to prevent the mark from being tampered with during transmission. The specific content of the added importance mark is not limited here as long as it can represent that the corresponding information has been modified.

[0109] While the Beidou differential module sends positioning information, other monitoring terminals also obtain location information from the monitoring background transmitter.

[0110] S48: The Beidou positioning chip modules of other monitoring terminals send the acquired location information to the monitoring background. The other monitoring terminals are the monitoring terminals except the target monitoring terminal among the odd-numbered location monitoring terminals.

[0111] During the process of sending positioning information and location information, the information can be encrypted and transmitted using 5G communication technology.

[0112] While obtaining the location information of the transmission line based on the Beidou positioning chip module, the movement information of the transmission line is also obtained based on the mobile sensor.

[0113] S49: The mobile sensor obtains the movement information between adjacent moments in the transmission line at different moments, and sends the movement information to the monitoring background.

[0114] The specific implementation method of step S49 is the same as that of the aforementioned step S22, which will not be repeated here.

[0115] The monitoring background determines the movement state of the transmission line based on the information sent by each location monitoring terminal, so as to combine the movement information to determine whether the transmission line is dancing, wind deviation and breeze vibration.

[0116] S410: Based on the location information, a first monitoring result is generated to determine whether the power transmission line generates dancing, wind deviation, and breeze vibration.

[0117] Existing technologies can be used to monitor power movement, wind deviation, and breeze vibration based on specific locations. That is, based on multiple location information of the power transmission line at multiple times, a dynamic model of the power transmission line is generated, and then it is determined whether the operating state of the dynamic model meets the power transmission line power movement detection standard, the power transmission line wind deviation detection standard, and the power transmission line breeze vibration detection standard. The first monitoring result includes the results of whether the transmission line is moving, whether it is wind deflected, and whether it is vibrating in a breeze. Alternatively, the first monitoring result may also only include the results of the power transmission line moving, wind deflected, or breeze vibrating. The reduction in the amount of result data can save subsequent data processing time and improve monitoring efficiency.

[0118] S411: Based on the movement information, a second monitoring result is generated to determine whether the power transmission line generates dancing, wind deviation, and breeze vibration.

[0119] Existing technologies can still be used to monitor dancing, wind deviation, and breeze vibration based on specific movement conditions. That is, the movement information of the transmission line at multiple times is respectively input into the existing transmission line dancing monitoring model, wind deviation monitoring model, and breeze vibration monitoring model. The result of the model output is whether dancing, wind deviation, or breeze vibration is generated. In the second monitoring result, it may include the results of whether the transmission line is dancing, whether it is wind deflected, and whether it is breeze vibrating, or it may only include the results of the transmission line dancing, wind deviation, or breeze vibration. The reduction in the amount of result data can save subsequent data processing time and improve monitoring efficiency.

[0120] Of course, in order to improve the efficiency of generating the second monitoring result and speed up monitoring, it is also possible to not use various monitoring models, but to simplify the monitoring model into a series of numerical values ​​in the time dimension that can characterize dancing, wind deviation, and breeze vibration, that is, a numerical chain.

[0121] Specifically, the above step S411 may include:

[0122] Step B1: Compare the movement information with the power line galloping threshold chain, and generate the power line galloping monitoring result according to the comparison result.

[0123] The movement information may be a specific vector of the movement of the transmission line at different times, for example: at the first moment, the speed is 0.5 m / s when it moves 30° east of north, and at the second moment, the speed is 0.5 m / s when it moves 30° west of south.

[0124] The transmission line galloping threshold chain can be the motion characteristics of the transmission line that produces galloping, for example: the speed first increases to a certain value, then decreases to zero, then increases to the value, and then decreases to zero. It can also be a set of transmission line galloping feature vectors, for example: greater than 0.2m / s and 0m / s.

[0125] If the movement information meets the transmission line galloping threshold chain, it is determined that the transmission line is galloping. If the movement information does not meet the transmission line galloping threshold chain, it is determined that the transmission line is not galloping.

[0126] Step B2: Compare the movement information with the transmission line wind deviation threshold chain, and generate the transmission line wind deviation monitoring result according to the comparison result.

[0127] The transmission line wind deviation threshold chain can be the movement characteristics of the transmission line that generates wind deviation, for example: after displacement occurs, no more displacement occurs within a preset period of time. It can also be a set of wind deviation characteristic vectors of the transmission line, for example: displacement is greater than 0.2m, followed by displacement of 0m.

[0128] If the movement information meets the transmission line wind deviation threshold chain, it is determined that the transmission line has wind deviation. If the movement information does not meet the transmission line wind deviation threshold chain, it is determined that the transmission line has not wind deviation.

[0129] Step B3: Compare the movement information with the power line breeze vibration threshold chain, and generate the power line breeze vibration monitoring result according to the comparison result.

[0130] The threshold chain of breeze vibration of the transmission line can be the motion characteristics of the transmission line that generates breeze vibration, for example: continuous small changes in displacement in a short time. It can also be a set of breeze vibration characteristic vectors of the transmission line, for example: within 0.5s, the displacement is between 0.1m and 0.2m, and then the displacement is between -0.1m and -0.2m.

[0131] If the movement information meets the transmission line breeze vibration threshold chain, it is determined that the transmission line has breeze vibration. If the movement information does not meet the transmission line breeze vibration threshold chain, it is determined that the transmission line has not had breeze vibration.

[0132] Step B4: Based on the dancing monitoring result, the wind deviation monitoring result and the breeze vibration monitoring result, a second monitoring result is generated to determine whether the power transmission line generates dancing, wind deviation and breeze vibration.

[0133] The results of transmission line dancing, wind deviation and breeze vibration are available. By combining these results together, we get the second monitoring result.

[0134] S412: Determine whether the first monitoring result is the same as the second monitoring result. If yes, execute S413; if no, execute S414.

[0135] Generally speaking, the monitoring results only include one state. That is, normal (no dancing, no wind deviation, no breeze vibration), dancing, wind deviation or breeze vibration. It may also include multiple states (in between two states, both states are included). For example: dancing and breeze vibration. Therefore, it is necessary to compare each state in the first monitoring result with each state in the second monitoring result. Only when each state in the first monitoring result corresponds to each state in the second monitoring result, can it be determined that the first monitoring result is the same as the second monitoring result.

[0136] S413: Based on the first monitoring result or the second monitoring result, determine whether the power transmission line generates dancing, wind deviation, and breeze vibration.

[0137] The first monitoring result is the same as the second monitoring result, indicating that the monitoring results based on Beidou positioning and sensors are the same, and the monitoring results are highly accurate. The state indicated in the first monitoring result or the second monitoring result can be used to determine the current state of the transmission line. For example, if the first monitoring result indicates that the transmission line is dancing, then it is determined that the transmission line is currently dancing, and then corresponding measures are taken to solve the problem of the transmission line dancing.

[0138] S414: Based on the wind force level of the environment in which the transmission line is located, the first monitoring result and the second monitoring result, determine whether the transmission line generates dancing, wind deviation and breeze vibration.

[0139] The first monitoring result is different from the second monitoring result, indicating that there are differences in the monitoring results based on Beidou positioning and sensors. The accuracy of the two monitoring results remains to be considered. At this time, it is necessary to combine other factors to determine whether the transmission line produces dancing, wind deviation, and breeze vibration. One of the other factors may be the wind force level in the environment where the transmission line is located. Of course, other factors may also include on-site inspections by drones.

[0140] The wind force level of the environment in which the transmission line is located can be inferred from historical wind data or obtained from weather data. Different wind force levels may have different dynamic effects on the transmission line. Corresponding different wind force levels to dancing, wind deviation, and breeze vibration, for example: 1-3 wind force-differential vibration, 4-5 wind force-dancing, and above 5 wind force-wind deviation, can assist in monitoring the dancing of the transmission line.

[0141] The wind force level, the first monitoring result and the second monitoring result are comprehensively considered to make judgments such as dancing. In addition to directly taking the first monitoring result or the second monitoring result that is the same as the monitoring result corresponding to the wind force level as the final result of the judgment such as dancing, different methods can be used to determine the final judgment result based on the difference between the first monitoring result and the second monitoring result.

[0142] Specifically, the above step S414 may include:

[0143] Step C1: Determine whether the first monitoring result and the second monitoring result are completely different. If yes, execute step C2; if no, execute step C3.

[0144] When the first monitoring result or the second monitoring result contains two dynamics, for example: the first monitoring result contains dancing and breeze vibration, and the second monitoring result contains dancing. For another example: the first monitoring result contains dancing and breeze vibration, and the second monitoring result contains no dancing, no wind deviation, and no breeze vibration. If there are still some identical parts, it means that the accuracy of the identical parts is higher and can be used as the final monitoring result. If they are completely different and the accuracy of the two monitoring results is questionable, the third condition can be used to make a decision.

[0145] Step C2: Based on the wind force level of the environment in which the power transmission line is located, the target dynamics are determined from the dancing, wind deviation and breeze vibration, and the target dynamics are used as the final monitoring result of the power transmission line.

[0146] The contents of the first monitoring result are completely different from those of the second monitoring result. Currently, it is impossible to determine which monitoring result is accurate. At this time, you can select the wind force level of the environment in which the transmission line is located to determine the final monitoring result. Because based on experience, different wind force levels will lead to different movement states of the transmission line. For example: 1-3 wind force-differential vibration, 4-5 wind force-dancing, and above 5 wind force-wind deviation, which can assist in monitoring the dancing of the transmission line. At this time, the state selected based on the wind force level will be used as the currently determined state of the transmission line. For example: the current wind force is level 3, which determines that the transmission line is currently generating breeze vibration.

[0147] Step C3: Determine the same monitoring result from the first monitoring result and the second monitoring result, and use the same monitoring result as the final monitoring result of the transmission line.

[0148] The first monitoring result and the second monitoring result have the same content, which means that the same content is obtained from different methods and is accurate. In this case, the same content in the first monitoring result and the second monitoring result can be used as the final monitoring result. For example, the first monitoring result contains dancing and breeze vibration, and the second monitoring result contains dancing, which determines that the power transmission line is currently dancing.

[0149] The above is to combine the monitoring results determined based on the location information obtained by the Beidou positioning chip module with the monitoring results determined based on the mobile information obtained by the mobile sensor, that is, to make a combined judgment of the two monitoring results. In addition, the mobile information can be used to correct the location information, and the final monitoring result can be directly obtained based on the corrected location information, or the location information can be used to correct the mobile information, and the final monitoring result can be directly obtained based on the corrected mobile information. This can reduce the judgment steps of monitoring and improve the monitoring efficiency of transmission line swaying, etc.

[0150] At this point, the transmission line dancing monitoring method based on Beidou positioning provided in the embodiment of the present application has been fully explained.

[0151] Based on the same inventive concept, as an implementation of the above method, an embodiment of the present application also provides a transmission line sway monitoring system based on Beidou positioning.

[0152] Figure 5 The structure of the transmission line dancing monitoring system based on Beidou positioning in the embodiment of the present application is shown in FIG. Figure 1 , see Figure 5 As shown, the system may include: a monitoring background 51 and a position monitoring terminal 52. The position monitoring terminal 52 may include: a Beidou positioning chip module 521 and a mobile sensor 522.

[0153] The location monitoring terminal 52 is installed on the transmission line. The Beidou positioning chip module 521 is used to obtain Beidou positioning information. The mobile sensor 522 is used to perform displacement monitoring. The location monitoring terminal 52 is connected to the monitoring background 51.

[0154] When the system is running:

[0155] The Beidou positioning chip module 521 is used to obtain the position information of the power transmission line at different times under the current position, and send the position information to the monitoring background 51.

[0156] The motion sensor 522 is used to obtain the motion information between adjacent moments in the different moments at the current position of the power transmission line, and send the motion information to the monitoring background 51.

[0157] The monitoring background 51 is used to determine whether the power transmission line generates dancing, wind deviation and breeze vibration based on the position information and the movement information.

[0158] Furthermore, as a Figure 5 As a refinement and expansion of the system shown, an embodiment of the present application also provides a transmission line sway monitoring system based on Beidou positioning.

[0159] Figure 6 The structure of the transmission line dancing monitoring system based on Beidou positioning in the embodiment of the present application is shown in FIG. Figure 2 , see Figure 6 As shown, the system may include: a monitoring background 61 and a position monitoring terminal 62. The position monitoring terminal 62 may include: a Beidou positioning chip module 621, a mobile sensor 622, a wire CT power supply module 623, a solar power supply module 624, a controller 625, a positioner 626 and a Beidou differential correction module 627.

[0160] Among them, an odd number of position monitoring terminals 62 are installed on the transmission line. The Beidou positioning chip module 621 and the mobile sensor 622 use the power provided by the solar power supply module 624 by default. The controller 625 is connected to the wire CT power supply module 623 and the solar power supply module 624 respectively. The locator 626 can obtain the installation position of each position monitoring terminal 62 in the transmission line. The locator 626 is connected to the Beidou differential correction module 627 and the Beidou positioning chip module 621 respectively. The Beidou differential correction module 627, the Beidou positioning chip module 621 and the mobile sensor 622 are respectively connected to the monitoring background 61.

[0161] While the system is running:

[0162] The controller 625 is used to determine whether the remaining power of the solar power supply module 624 is less than the preset power; if so, the wire CT power supply module 623 is controlled to provide power to the Beidou positioning chip module 621 and the mobile sensor 622; if not, the solar power supply module 624 is controlled to provide power to the Beidou positioning chip module 621 and the mobile sensor 622.

[0163] When the controller 625 executes the control of the conductor CT power supply module 623 to provide power to the Beidou positioning chip module 621 and the mobile sensor 622, it is specifically used to determine the importance of the transmission line in the transmission network; judge whether the importance is greater than a preset degree; if so, control the conductor CT power supply module 623 to provide power to the Beidou positioning chip module 621 and the mobile sensor 622 until the position monitoring terminal 62 stops being used; if not, control the conductor CT power supply module 623 to provide power to the Beidou positioning chip module 621 and the mobile sensor 622 before the solar power supply module 624 is fully charged.

[0164] The Beidou positioning chip module 621 is used to obtain the position information of the power transmission line at different times under the current position.

[0165] The locator 626 is used to determine the target monitoring terminal installed at the middle position among the odd-numbered position monitoring terminals 62 .

[0167] The Beidou positioning chip modules 621 of other monitoring terminals send the acquired location information to the monitoring background 61 . The other monitoring terminals are the monitoring terminals among the odd-numbered location monitoring terminals 62 except the target monitoring terminal.

[0168] The motion sensor 622 is used to obtain the motion information between adjacent moments in the different moments at the current position of the power transmission line, and send the motion information to the monitoring background 61.

[0169] The monitoring backend 61 is used to determine the movement state of the power transmission line based on the information sent by each position monitoring terminal 62, so as to judge whether the power transmission line generates dancing, wind deviation and breeze vibration in combination with the movement information.

[0170] The monitoring backend 61 includes: a first monitoring unit 611, a second monitoring unit 612, a judgment unit 613, a first determination unit 614, and a second determination unit 615. The first monitoring unit 611 and the second monitoring unit 612 are connected to the judgment unit 613, respectively, and the judgment unit 613 is connected to the first determination unit 614 and the second determination unit 615, respectively.

[0171] The first monitoring unit 611 is used to generate a first monitoring result of whether the power transmission line generates dancing, wind deviation and breeze vibration based on the position information.

[0172] The second monitoring unit 612 is used to generate a second monitoring result of whether the power transmission line generates dancing, wind deviation and breeze vibration based on the movement information.

[0173] The second monitoring unit 612 is specifically used to compare the movement information with the transmission line dancing threshold chain, and generate the dancing monitoring result of the transmission line according to the comparison result; compare the movement information with the transmission line wind deviation threshold chain, and generate the wind deviation monitoring result of the transmission line according to the comparison result; compare the movement information with the transmission line breeze vibration threshold chain, and generate the breeze vibration monitoring result of the transmission line according to the comparison result; based on the dancing monitoring result, the wind deviation monitoring result and the breeze vibration monitoring result, generate the second monitoring result of whether the transmission line generates dancing, wind deviation and breeze vibration.

[0174] The judging unit 613 is used to judge whether the first monitoring result is the same as the second monitoring result. If yes, the process proceeds to the first determining unit 614; if no, the process proceeds to the second determining unit 615.

[0175] The first determining unit 614 is used to determine whether the power transmission line generates dancing, wind deviation, and breeze vibration based on the first monitoring result or the second monitoring result.

[0176] The second determining unit 615 is used to determine whether the transmission line generates dancing, wind deviation and breeze vibration based on the wind force level of the environment in which the transmission line is located, the first monitoring result and the second monitoring result.

[0177] The second determination unit 615 is specifically used to determine whether the first monitoring result is completely different from the second monitoring result; if so, based on the wind force level of the environment in which the transmission line is located, determine the target dynamics from the dancing, wind deviation and breeze vibration, and use the target dynamics as the final monitoring result of the transmission line; if not, determine the same monitoring result from the first monitoring result and the second monitoring result, and use the same monitoring result as the final monitoring result of the transmission line.
