[0035] See also Figure 1 An embodiment of the present invention provides a cable icing status monitoring method, comprising:

[0036] S1. Acquire real-time sensing data of the target cable, where the real-time sensing data includes real-time stress sensing data and real-time temperature sensing data;

[0037] In the embodiment of the present invention, the target cable can be various line cables, including line conductors, lightning arresters, etc. The target cable can be detected based on distributed optical fiber strain sensing technology to obtain real-time sensing data; historical sensing data can be obtained through a database. The real-time stress sensing data may include stress values ​​of a preset number of stress points within a preset range.

[0038] S2. When the real-time temperature sensing data meets the preset freezing condition, determining whether the real-time temperature sensing data decreases over time;

[0039] In an embodiment of the present invention, the real-time temperature sensing data can be compared with the freezing point temperature, and whether the preset freezing condition is met is determined according to the comparison result. For example, when the real-time temperature sensing data is less than the freezing point temperature, it is determined that the preset freezing condition is met.

[0040] In the embodiment of the present invention, it is possible to determine whether the real-time temperature sensing data decreases over time by comparing the size of the temperature sensing data within a period of time.

[0041] S3. If the real-time temperature sensing data decreases over time, it is determined that the target cable is in an ice-covered state; if the real-time temperature sensing data does not decrease over time, when the stress distribution trend of the target cable is a distribution trend from small to large, it is determined that the target cable is in an ice-covered state; wherein the stress distribution trend is determined based on the real-time stress sensing data.

[0042] In an embodiment of the present invention, if the real-time temperature sensing data decreases over time, and the real-time sensed temperature is lower than the freezing point, it can be determined that the target cable is in an ice-covered state; if the real-time temperature sensing data does not decrease over time, the target cable may be in an ice-covered state. By analyzing the stress distribution trend of the target cable, when the stress distribution trend is a distribution trend from small to large, it can be determined that the target cable is ice-covered, thereby being able to determine that the target cable is in an ice-covered state.

[0043] The embodiment of the present invention obtains real-time sensing data of the target cable. When the target cable meets the preset icing condition, if the real-time temperature sensing data decreases over time, it is determined that the target cable is in an ice-covered state; if the real-time temperature sensing data does not decrease over time, then when the stress distribution trend of the target cable is a distribution trend from small to large, it is determined that the target cable is in an ice-covered state. There is no need to use sensors based on electrical signals for measurement, and it will not be affected by strong electromagnetic interference around the wires, thereby effectively ensuring the accuracy and reliability of the real-time sensing data.

[0044] In one embodiment, S1, obtaining real-time sensing data of a target cable includes:

[0045] Based on the distributed optical fiber strain sensing technology, optical fiber is laid along the target cable, and the Brillouin scattering technology is used to monitor the optical fiber of the target cable to obtain real-time perception data of the target cable.

[0046] In the embodiment of the present invention, the distributed optical fiber sensor is a sensor that uses a unique distributed optical fiber detection technology to measure or monitor the spatial distribution and time-varying information along the optical fiber transmission path. The distributed optical fiber strain sensor can identify changes in cable stress caused by ice-covered conditions by sensing the stress sensing data and temperature sensing data of the cable. The principle of the distributed optical fiber sensing system is to use optical fiber as a sensing sensitive element and a transmission signal medium at the same time, and send the transmitted signal to the monitoring host computer for subsequent processing and analysis.

[0047] The embodiment of the present invention can detect the real-time stress perception data and real-time temperature perception data of the cable through a distributed optical fiber strain sensor, specifically: laying optical fiber along the distribution network cable, tightly combining the optical fiber and the cable, so that the temperature and strain of the optical fiber and the cable are kept as consistent as possible, and the temperature and stress of the cable are reflected by the temperature and stress of the optical fiber. Among them, the installation method of the distributed optical fiber strain sensor can be set according to actual conditions, and the embodiment of the present invention is not limited here. Among them, the real-time stress perception data can include the stress values ​​of a preset number of stress points within a preset range. For example, when it is necessary to detect the stress value of the current stress point, the stress values ​​of the remaining points within the surrounding preset range can be obtained.

[0048] The embodiment of the present invention obtains real-time sensing data of the target cable based on distributed optical fiber strain sensing technology and Brillouin scattering technology, and is not affected by strong electromagnetic interference around the wire, thereby ensuring the accuracy and reliability of the real-time sensing data.

[0049] In one embodiment, the preset freezing condition is that the real-time temperature sensing data is below the freezing point.

[0050] In an embodiment of the present invention, the temperature below the freezing point of real-time temperature sensing data is used as a condition for determining whether the target cable is frozen. For example, when the real-time temperature data is below 0°C, the target cable is determined to meet the freezing conditions. When the target cable reaches the freezing conditions, further monitoring can be performed on whether the target cable is covered with ice. When the target cable does not reach the freezing conditions, the target cable is determined to be not covered with ice. The real-time sensing data is re-acquired and re-determined whether the preset freezing conditions are met, which can effectively improve the accuracy of cable icing status monitoring.

[0051] In one embodiment, before determining whether the real-time temperature sensing data decreases over time, the process includes:

[0052] Determine a stress perception curve based on historical stress perception data and real-time stress perception data;

[0053] In the embodiment of the present invention, the stress perception curve is used to represent the stress change of the cable within a period of time.

[0054] Determine the stress perception data increase over time according to the stress perception curve.

[0055] The embodiment of the present invention analyzes the stress perception curve. When the stress perception data in the stress perception curve increases with time, it may be caused by cable icing. In this case, it is necessary to judge the temperature perception data again to further determine the specific reason why the stress perception data increases with time.

[0056] The embodiment of the present invention establishes a stress perception curve to determine whether the stress perception data increases over time, and then judges whether the real-time temperature perception data decreases over time. When both conditions are met, it can be judged that the current target cable is in an ice-covered state, thereby effectively improving the accuracy of cable ice-covered state monitoring.

[0057] In one embodiment, the method for determining the stress distribution trend includes:

[0058] Determine stress values ​​of a preset number of stress points within a preset range according to real-time stress sensing data;

[0059] Based on all stress values, the stress distribution trend of the target cable is determined.

[0060] In an embodiment of the present invention, stress values ​​of a preset number of stress points are determined based on real-time stress sensing data, and then a stress distribution trend can be obtained. By judging the stress distribution trend, it is determined whether the stress distribution trend is a distribution trend from small to large. If so, it indicates that the cable is in an ice-covered state. If not, it indicates that the temperature does not decrease over time due to an increase in ambient temperature, and the cable is in an un-iced state.

[0061] The embodiment of the present invention determines the stress values ​​of a preset number of stress points through real-time stress sensing data, can monitor the stress state of the cable in real time, and can accurately identify whether the cable is in an ice-covered state by judging the stress distribution trend. It can accurately judge the ice-covered state under severe weather conditions and avoid line damage caused by ice-covered.

[0062] In one embodiment, after acquiring the real-time sensing data of the target cable, the method further includes:

[0063] Filter the real-time perception data.

[0064] In the embodiment of the present invention, by filtering the real-time sensing data, the influence of different noise sources in the real-time sensing data can be effectively reduced. For example, when the cable is blown by the wind and oscillates, high-frequency noise will be generated, which will interfere with subsequent observation and analysis. The embodiment of the present invention can selectively remove noise in different frequency bands by applying appropriate filters, retain signal components related to the ice coating state, and then obtain processed stress sensing data and temperature sensing data to improve the accuracy of subsequent target cable ice coating state monitoring.

[0065] In one embodiment, when it is determined that the target cable is covered with ice, the cable can be monitored, for example, an alarm signal can be issued, so that the console can determine the ice point in the ice-covered state according to the alarm signal, and then start the snow melting program for the ice point.

[0066] The implementation of the embodiments of the present invention has the following beneficial effects:

[0067] The embodiment of the present invention obtains real-time sensing data of the target cable. When the target cable meets the preset icing condition, if the real-time temperature sensing data decreases over time, it is determined that the target cable is in an ice-covered state; if the real-time temperature sensing data does not decrease over time, then when the stress distribution trend of the target cable is a distribution trend from small to large, it is determined that the target cable is in an ice-covered state. There is no need to use sensors based on electrical signals for measurement, and it will not be affected by strong electromagnetic interference around the wires, thereby effectively ensuring the accuracy and reliability of the real-time sensing data.

[0068] Furthermore, the embodiments of the present invention can determine the stress values ​​of a preset number of stress points through real-time stress sensing data, and can monitor the stress state of the cable in real time. By judging the stress distribution trend, it can accurately identify whether the cable is in an ice-covered state, and can accurately judge the ice-covered state under severe weather conditions, and can avoid line damage caused by ice covering.
