[0055] Figure 1 A schematic diagram of an application scenario of a transmission line conductor monitoring method provided in an embodiment of the present application. At present, the conventional technology for monitoring the deicing and jumping of transmission lines in power grids is basically implemented by video monitoring. Figure 1One to two cameras are installed on the transmission line tower shown, and the cameras are used to capture the movement of the conductors. Then, the de-icing condition of the conductors is determined through manual monitoring or image / video analysis methods.

[0056] However, the above-mentioned traditional monitoring methods for monitoring deicing jumps have the following problems: the camera needs to be turned on for a long time to maintain shooting, resulting in a large power consumption of the entire monitoring device. In addition, in winter, the camera lens may be blocked by ice and snow, making it impossible to clearly shoot the wire from a distance. Since the posture of the wire is monitored by image video monitoring, it is usually only possible to qualitatively analyze the deicing jump of the wire, but not quantitatively.

[0057] Based on the above reasons, the present invention provides a method, device, system and readable storage medium for monitoring a transmission line conductor.

[0058] In one embodiment, Figure 2 As shown, the present application provides a method for monitoring a transmission line conductor, the method comprising:

[0059] Step 202: in response to the conductor temperature data of the transmission line conductor satisfying the temperature threshold condition, the deicing jump duration is acquired based on the conductor acceleration data and the conductor inclination angle data of the transmission line conductor.

[0060] Among them, when the conductor temperature data of the transmission line conductor meets the temperature threshold condition, the monitoring equipment enters the de-icing jump monitoring condition, otherwise it enters the conductor ice-free condition. It can be understood that since the conductor icing conditions in different regions may be affected by geographical factors such as local ambient air pressure and wind speed, the above-mentioned temperature threshold conditions can be set according to the climatic conditions of the area where the transmission line conductor is located, so as to maintain de-icing jump monitoring and analysis when the transmission line conductor may be frozen. The conductor acceleration data can be obtained by monitoring the acceleration sensor set on the conductor of the transmission line, which can characterize the acceleration change of the monitored part of the transmission line conductor. The conductor inclination angle data can be obtained by monitoring the angle sensor set on the conductor of the transmission line, which can characterize the change of the conductor inclination angle of the transmission line conductor along the line direction. The de-icing jump duration can characterize the duration of the conductor shaking and jumping back and forth due to the shedding of ice after the transmission line conductor is frozen. It can be understood that the setting method of the above-mentioned temperature threshold condition is not limited to the implementation method mentioned in the above embodiment. As long as it can characterize the conditions for icing of the conductors of the local transmission line, the present application does not specifically limit the setting of the temperature threshold condition.

[0061] Specifically, when the conductor temperature data of the transmission line conductor meets the temperature threshold condition, based on the obtained conductor acceleration data and conductor inclination angle data of the transmission line conductor, the de-icing jump duration can be obtained according to the changes in conductor acceleration and conductor inclination angle of the monitored part of the transmission line conductor.

[0062] Step 204, obtaining the conductor jitter trajectory according to the deicing jump duration and the conductor acceleration data.

[0063] The conductor shaking trajectory may include a moving trajectory of the monitored part of the transmission line conductor in space. It is understandable that when ice on the transmission line conductor falls off, the transmission line conductor will shake and jump back and forth, and during the period when the transmission line conductor falls off and jumps, the monitored part of the transmission line conductor may form a moving trajectory that changes with time.

[0064] Specifically, based on the conductor acceleration data, the transmission line conductor speed data and the transmission line conductor speed change during the transmission line conductor deicing jump period can be obtained; according to the transmission line conductor speed data and the transmission line conductor speed change, combined with the deicing jump duration, the conductor jitter trajectory can be obtained.

[0065] The above-mentioned transmission line conductor monitoring method can obtain the deicing jump duration based on the conductor acceleration data and conductor inclination angle data of the transmission line conductor obtained through monitoring when the conductor temperature data of the transmission line conductor meets the temperature threshold; based on the deicing jump duration and the conductor acceleration data, the conductor jitter trajectory of the transmission line conductor can be obtained. The present application does not need to turn on the camera for a long time to maintain image monitoring of the transmission line conductor, thereby reducing the power consumption of the equipment and reducing the monitoring cost of the deicing jump of the transmission line conductor. In addition, the present application can obtain accurate conductor motion data and conductor jitter trajectory based on the conductor acceleration data and conductor inclination angle data of the transmission line conductor, and can quantitatively analyze the deicing jump motion posture of the transmission line conductor.

[0066] In one embodiment, if Figure 3 As shown, based on the conductor acceleration data and the conductor inclination angle data of the transmission line conductor, the de-icing jump duration is obtained, including:

[0067] Step 302: Based on a first preset sampling frequency, sample to obtain wire acceleration data, where the wire acceleration data includes wire vertical acceleration data and wire horizontal acceleration data.

[0068] The first preset sampling frequency may include a sampling frequency of the wire acceleration data when the wire temperature data meets the temperature threshold condition. Exemplarily, the first preset sampling frequency may be greater than the sampling frequency of the wire acceleration data when the wire temperature data does not meet the temperature threshold condition, so as to improve the monitoring data acquisition density, thereby improving the accuracy of the wire jitter trajectory calculation. The wire vertical acceleration data may represent the component of the wire acceleration data in the vertical direction, and the wire horizontal acceleration data may represent the component of the wire acceleration data in the horizontal direction.

[0069] Specifically, the conductor vertical acceleration data and the conductor horizontal acceleration data of the transmission line conductor are obtained by sampling at a first preset sampling frequency.

[0070] Step S304: sampling to obtain wire inclination angle data based on a second preset sampling frequency.

[0071] The second preset sampling frequency may include a sampling frequency of monitoring data of a conductor inclination angle of a transmission line conductor along a line direction when the conductor temperature data meets a temperature threshold condition. Exemplarily, the second preset sampling frequency may be greater than a sampling frequency of monitoring data of a conductor inclination angle when the conductor temperature data does not meet the temperature threshold condition, so as to increase the density of monitoring data collection, thereby improving the accuracy of conductor jitter trajectory calculation.

[0072] Step S306, in response to the absolute value of the wire vertical acceleration data satisfying the jump start threshold condition, the deicing jump duration is obtained based on the wire vertical acceleration data and the wire inclination angle data.

[0073] Among them, it can be understood that when the transmission line conductor de-ices and jumps, the absolute value of the conductor vertical acceleration data undergoes a change process. When the conductor vertical acceleration data increases from zero to greater than a preset threshold, it is confirmed that the transmission line conductor begins to de-ice and jump. Exemplarily, the jump start threshold condition may include that the absolute value of the conductor vertical acceleration data is greater than 1g (a standard gravity acceleration). It should be understood that the above-mentioned jump start threshold condition is not limited to the implementation method mentioned in the above-mentioned embodiment, and the present application does not specifically limit the setting method of the jump start threshold condition.

[0074] Specifically, when the absolute value of the wire vertical acceleration data satisfies the jump start threshold condition, the deicing jump duration can be obtained based on the obtained wire vertical acceleration data and wire inclination angle data.

[0075] In some embodiments, Figure 4 As shown, based on the wire vertical acceleration data and the wire inclination angle data, the de-icing jump duration is obtained, including:

[0076] Step S402, in response to the absolute value of the wire vertical acceleration data satisfying the jump start threshold condition, obtaining the deicing jump start time.

[0077] Specifically, if the absolute value of the vertical acceleration data of the transmission line conductor meets the preset jump start threshold condition, the start time of the de-icing jump of the transmission line conductor is recorded.

[0078] Step S404: when the deicing jump start time has been obtained, in response to the absolute value of the wire vertical acceleration data and the wire inclination angle data satisfying the jump end threshold condition, the deicing jump end time is obtained.

[0079] It can be understood that during the deicing jump of the transmission line conductor, the transmission line conductor will produce an angle change along the line direction. Exemplarily, after the deicing jump begins, the conductor inclination angle data and the conductor vertical acceleration data can undergo a change process from large to small. When the conductor inclination angle data is lower than the preset inclination angle threshold and the conductor vertical acceleration data is lower than the preset acceleration threshold, it can be determined that the deicing jump of the transmission line conductor is over.

[0080] Specifically, after the de-icing jumping process of the transmission line conductor begins, the conductor vertical acceleration data and the conductor inclination angle data are obtained; if the absolute value of the conductor vertical acceleration data and the conductor inclination angle data meet the jumping end threshold conditions, it is determined that the transmission line conductor de-icing jumping process is over, and the end time of the transmission line conductor de-icing jumping is recorded.

[0081] Step S406, obtaining the deicing jump duration based on the deicing jump start time and the deicing jump end time.

[0082] Specifically, by performing difference processing on the deicing jump end time and the deicing jump start time, the deicing jump duration of the deicing jump process of the transmission line conductor can be obtained.

[0083] In one embodiment, if Figure 5 As shown in the figure, according to the duration of ice shedding jump and the wire acceleration data, the wire jitter trajectory is obtained, including:

[0084] Step S502: Calculate the conductor displacement data based on the deicing jump duration, the conductor vertical acceleration data, and the conductor horizontal acceleration data.

[0085] Among them, the conductor displacement data can characterize the displacement of the monitored part of the transmission line conductor in space during the conductor de-icing and jumping.

[0086] Specifically, according to the obtained de-icing jump duration, conductor vertical acceleration data and conductor horizontal acceleration data, the conductor displacement data of the transmission line conductor can be calculated.

[0087] Step S504, based on the conductor displacement data, obtaining the conductor jitter position point; the conductor jitter position point is the spatial position coordinate point of the monitored part of the transmission line conductor.

[0088] It can be understood that, based on the obtained conductor displacement data, the spatial position change of the monitored part of the transmission line conductor before and after the ice shedding and jumping occurs can be obtained, thereby obtaining the specific position coordinates of the monitored part of the transmission line conductor in space.

[0089] Specifically, based on the obtained conductor displacement data, the conductor shaking position point of the monitored part of the transmission line conductor during the de-icing jump period can be obtained.

[0090] Step S506, connecting the wire shaking position points to obtain the wire shaking trajectory.

[0091] Specifically, by connecting the wire shaking position points monitored during the deicing jump, the wire shaking trajectory of the transmission line wire during the deicing jump can be obtained. It can be understood that the more wire shaking position points monitored, the closer the wire shaking trajectory formed after connection is to the actual wire deicing jump movement posture.

[0092] In some embodiments, Figure 6 As shown, the method also includes:

[0093] Step S602, obtaining wire jitter amplitude data based on the wire displacement data.

[0094] Among them, the conductor jitter amplitude data represents the absolute value of the maximum displacement of the conductor from the equilibrium position in one jitter back and forth when the transmission line conductor jumps due to deicing. It can be understood that during the deicing jump, as the transmission line conductor continues to shake back and forth, the conductor jitter amplitude data obtained by monitoring will also change. For example, as the conductor deicing jump process proceeds, the value of the conductor jitter amplitude data gradually decreases until the conductor no longer jitters.

[0095] Specifically, based on the obtained conductor displacement data, the conductor jitter amplitude data of the transmission line conductor during the de-icing jumping process can be obtained.

[0096] Step S604, based on the conductor jitter amplitude data, obtain the maximum jitter amplitude data of the transmission line conductor.

[0097] The maximum jitter amplitude data may be the maximum value of the conductor jitter amplitude data obtained within a de-icing jump monitoring cycle.

[0098] Specifically, according to the conductor jitter amplitude data obtained within a de-icing jump monitoring cycle, the maximum jitter amplitude data of the transmission line conductor can be obtained.

[0099] Step S606, obtaining conductor jitter period data of the transmission line conductor based on the conductor acceleration data.

[0100] Among them, the conductor jitter cycle data can represent the time it takes for the conductor to jitter back and forth during the ice shedding and jumping of the transmission line conductor.

[0101] Specifically, according to the conductor acceleration data obtained internally, the conductor jitter period data of the transmission line conductor can be obtained.

[0102] Step S608, uploading the maximum jitter amplitude data and the wire jitter period data.

[0103] It is understandable that the maximum jitter amplitude data and the conductor jitter cycle data are affected by the weight of ice cubes shed by the de-icing and jumping of the transmission line conductor. Furthermore, according to the maximum jitter amplitude data and the conductor jitter cycle data obtained by monitoring, it is possible to quantitatively monitor the motion parameters of the conductor de-icing and jumping process, so that the overall ice hanging condition of the transmission line conductor can be known according to the monitoring data. For example, if the maximum jitter amplitude data is larger and the conductor jitter cycle data is longer, it means that the weight of ice cubes shed by the conductor de-icing and jumping is larger, which reflects that the ice hanging condition of the local transmission line conductor is more serious.

[0104] Specifically, the obtained maximum jitter amplitude data and conductor jitter period data are uploaded to reflect the ice hanging situation of the local transmission line conductors in the monitoring area.

[0105] In one of the embodiments, in response to the conductor temperature data satisfying a temperature threshold condition, the conductor monitoring data is uploaded based on a preset upload frequency; the conductor monitoring data includes conductor acceleration data and conductor inclination angle data.

[0106] Among them, exemplarily, the preset upload frequency can be higher than the monitoring data upload frequency when the conductor temperature data does not meet the temperature threshold condition. It can be understood that the change in the ambient temperature around the transmission line is a gradual process. When the conductor temperature data does not meet the temperature threshold condition, the transmission line conductor will not freeze, and a too high monitoring data upload frequency is not required at this time. In the case where the conductor temperature data meets the temperature threshold condition, due to the need for accurate de-icing jump monitoring, the remote master station that monitors the operation of the transmission lines in various regions needs to obtain more monitoring data. At this time, the preset upload frequency can be set to be higher than the monitoring data upload frequency when the conductor temperature data does not meet the temperature threshold condition, thereby providing more monitoring data for the remote master station to analyze de-icing jumps, thereby improving the accuracy of transmission line conductor monitoring. Further, in the case of sufficient data transmission bandwidth resources, the uploaded conductor monitoring data can also include conductor temperature data, etc.

[0107] Specifically, when the conductor temperature data meets the temperature threshold condition, the conductor monitoring data is uploaded at a preset upload frequency. For example, the conductor monitoring data can be uploaded to a remote master station that monitors the operation of power transmission lines in various regions.

[0108] In some embodiments, in response to the conductor temperature data not satisfying the temperature threshold condition, the conductor temperature data and the conductor inclination angle data are sampled and uploaded based on a third preset sampling frequency, and the sampling of the conductor acceleration data is stopped.

[0109] It can be understood that when the conductor temperature data does not meet the temperature threshold condition, the transmission line conductor will not freeze. At this time, each monitoring module does not need a very high sampling frequency, nor does it need to obtain the conductor acceleration data to analyze the de-icing jumping motion posture. Exemplarily, the third preset sampling frequency can be lower than the monitoring data sampling frequency when the conductor temperature data meets the temperature threshold condition, thereby reducing the power consumption of the monitoring device in the non-icing period.

[0110] Specifically, when the wire temperature data does not meet the temperature threshold condition, the wire temperature data and the wire inclination angle data are sampled and uploaded at a third preset sampling frequency, and the sampling of the wire acceleration data is stopped.

[0111] In order to make the purpose, technical solution and advantages of the present application more clear, the present application is further described in detail by taking the monitoring and analysis of the primary conductor deicing jumping process as an example. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0112] Exemplarily, when the conductor temperature data obtained through monitoring is greater than 0° C., the conductor temperature data and the conductor inclination angle data of the power line conductor are monitored and transmitted to the remote master station at a frequency of once every 5 minutes.

[0113] When the conductor temperature data obtained by monitoring is less than or equal to 0°C, the conductor acceleration data of the transmission line conductor is sampled, and the sampling frequency of the conductor acceleration data is set to 50Hz. The sampling frequency of the conductor temperature data and the conductor inclination angle data is modified to 1Hz, and the monitoring data is collected every second and uploaded to the remote master station that monitors the operation of the transmission line in the area.

[0114] Based on the conductor acceleration data, the vertical component of the conductor acceleration is analyzed. When the component in this direction is greater than 1g, it is determined that the conductor of the transmission line begins to de-ice and jump, and the data collection time is recorded as the de-icing start time t0. According to the continuously monitored conductor vertical acceleration data, if the conductor vertical acceleration data is zero for 1 second and the conductor inclination angle data is less than the preset angle threshold, it is determined that the de-icing jump process is over, and the end time is recorded as t1. After the de-icing jump process is over, the de-icing jump duration t is calculated by t=t1–t0.

[0115] Based on the duration t of the deicing jump and the obtained conductor acceleration data, the conductor jitter amplitude data in the vertical and horizontal directions are obtained. Based on all the conductor jitter amplitude data during the deicing jump, the maximum jitter amplitude data is obtained and uploaded. The conductor displacement data is calculated based on the conductor vertical acceleration data and the conductor vertical acceleration data during the deicing jump, and the conductor displacement data is converted into conductor jitter position points in space. After connecting the conductor jitter position points, the conductor jitter trajectory can be restored. Furthermore, based on the jitter trajectory, a simulated animation can be generated in the form of moving points, which can more intuitively observe the overall movement posture of the transmission line conductor when deicing and jumping.

[0116] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
