Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] The descriptions of "first", "second", etc. involved in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the technical features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a hardware monitoring method, device, electronic device and storage medium, which are respectively described below.

[0023] Figure 1 A schematic flow chart of an embodiment of the hardware monitoring method provided by the present invention is as follows: Figure 1 As shown, the hardware monitoring methods include: S101, determining the initial coverage range of the hardware to be monitored based on the first reflected wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead power transmission cable; S102, calculating the real-time coverage range of the hardware to be monitored based on the second reflected wave signal collected by the optical fiber sensor at each collection point within the range to be monitored in the optical fiber composite overhead transmission cable; the range to be monitored includes the initial coverage range and the preset range before and after the initial coverage range; S103: When the initial coverage range and the real-time coverage range do not overlap, it is determined that an abnormality occurs in the hardware to be monitored.

[0024] The embodiment of the present invention provides a method for monitoring abnormalities of pre-twisted fittings of optical fiber composite overhead power transmission cables, such as Figure 2 As shown, a possible implementation scenario of an embodiment of the present invention is a sensing optical fiber pre-distributed in the optical fiber composite overhead transmission cable, an optical fiber sensor is embedded in the sensing optical fiber, and the sensing optical fiber is evenly distributed over the entire length of the transmission cable to ensure that all installation positions of pre-twisted hardware are covered. Furthermore, in order to more accurately obtain the temperature distribution of the entire transmission cable, the optical fiber sensors are arranged at high-density intervals in the transmission cable to form a large-capacity dense grating array, and the grating spacing is less than the length of the hardware twisted wire. Furthermore, the sensing optical fiber is connected to the optical fiber demodulation instrument at the terminal of the transmission cable to collect the reflection wavelength changes of the optical fiber sensing signal in real time. Specifically, the demodulation instrument excites the optical fiber sensor in the optical fiber through a scanning light source to collect the reflection wavelength changes of the optical fiber sensing signal in real time.

[0025] In an embodiment of the present invention, the initial coverage range of the hardware to be monitored refers to the range of the hardware to be monitored covering the optical fiber composite overhead power transmission cable when the hardware to be monitored is installed. The initial coverage range of the hardware to be monitored can be calculated based on the first reflected wave signal of each collection point collected by the optical fiber sensor in the optical fiber composite overhead power transmission cable. The specific calculation method will be described in detail in the subsequent embodiments of the present invention.

[0026] In an embodiment of the present invention, the range to be monitored in the optical fiber composite overhead power transmission cable includes the initial coverage range and the preset range before and after the initial coverage range. To ensure the accuracy of monitoring the abnormal type of the hardware to be monitored, the range to be monitored should include the initial coverage range and be larger than the initial coverage range. Specifically, the range covered by a plurality of collection points before and after the initial coverage range can be determined as the range to be monitored, such as the initial coverage range and the range covered by the 10 collection points before and after it. The real-time coverage range of the hardware to be monitored can be calculated based on the second reflected wave signal collected by the optical fiber sensor at each collection point within the coverage range to be monitored. The real-time coverage range refers to the actual coverage range of the hardware to be monitored after the hardware to be monitored is installed on the optical fiber composite overhead power transmission cable and works for a period of time. The real-time coverage range may be the same as the initial coverage range, or it may be different from the initial coverage range.

[0027] In an embodiment of the present invention, based on the relationship between the initial coverage range and the real-time coverage range, it can be determined whether the hardware to be monitored has an abnormality. For example, when the initial coverage range is exactly the same as the real-time coverage range, it indicates that the hardware to be monitored has no abnormality. On the contrary, when the initial coverage range and the real-time coverage range are different, it indicates that the hardware to be monitored may have an abnormality.

[0028] The hardware monitoring method provided by the present invention determines the initial coverage range of the hardware to be monitored based on the first reflected wave signal collected by the optical fiber sensor distributed at each collection point in the optical fiber composite overhead power transmission cable, determines the range to be monitored in the optical fiber composite overhead power transmission cable based on the initial coverage range, calculates the real-time coverage range of the hardware to be monitored based on the second reflected wave signal collected by each collection point in the range to be monitored, determines whether the hardware to be monitored is abnormal through the relationship between the initial coverage range and the real-time coverage range, continuously obtains information through the sensor, and analyzes the information, so that the abnormality of the hardware to be monitored can be discovered in the first time, and the abnormal monitoring of the hardware to be monitored is more accurate and timely. As a possible implementation mode of the present invention, in this implementation mode, Figure 3 As shown, determining the initial coverage range to be monitored based on the first reflected wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead transmission cable includes: S301, calculating a first temperature value of each collection point based on a first reflected wave signal collected by an optical fiber sensor distributed at each collection point in the optical fiber composite overhead power transmission cable; S302, determining a first number of continuous collection points whose first temperature value is greater than a preset temperature threshold as collection points covered by hardware; the first number is greater than a preset number threshold; S303: Determine the initial coverage range of the hardware to be monitored based on the hardware coverage collection points.

[0029] In the embodiment of the present invention, since the change in the reflection wavelength of the optical fiber sensor in the sensing optical fiber is proportional to the temperature change, the temperature change at the optical fiber sensor can be accurately obtained by measuring the change in the reflection wavelength. Therefore, the first temperature value of each collection point can be calculated based on the first reflected wave signal collected by the optical fiber sensor distributed at each collection point in the optical fiber composite overhead power transmission cable.

[0030] In the embodiment of the present invention, the collection point covered by the fitting refers to the collection point covered by the fitting in the optical fiber composite overhead power transmission cable. Due to the coverage of the optical fiber composite overhead power transmission cable by the fitting, the temperature of the collection point within the coverage range of the fitting will be significantly higher than the temperature of other parts. Therefore, the collection point covered by the fitting can be determined based on the relationship between the temperature of the collection point and the preset temperature threshold. In the embodiment of the present invention, in order to prevent the influence of abnormal data on the monitoring results, it is necessary to ensure that the first temperature value of more than a preset first number of consecutive collection points is greater than the preset temperature threshold. For the convenience of explanation, taking a specific embodiment as an example, assuming that the length of the optical fiber composite overhead transmission cable is 1.6 meters, an optical fiber sensor is arranged every 10 centimeters, and a total of 16 collection points are arranged. The first temperature values ​​of each collection point calculated by the transmission wave signal collected by the optical fiber sensor at each collection point are: 24.8°C, 24.9°C, 25.3°C, 25.6°C, 25.8°C, 26.1°C, 26.6°C, 26.8°C, 27.0°C, 26.8°C, 26.6°C, 26.1°C, 25.8°C, 25.6°C, 24.9°C, 24.8°C, wherein the preset temperature threshold is 25°C, then it can be known that the temperature values ​​of the 3rd to 14th collection points are greater than the preset temperature threshold, indicating that the 3rd to 14th collection points are the hardware covered collection points, then it can be determined that the range of the optical fiber composite overhead transmission cable where the 3rd to 14th collection points are located is the initial coverage range.

[0031] The embodiment of the present invention determines the initial coverage range of the hardware to be monitored by collecting the temperature of the point, which facilitates the subsequent determination of the range to be monitored and the monitoring of the hardware status.

[0032] As a possible implementation mode of the present invention, in this implementation mode, Figure 4As shown, the first temperature value of each collection point is calculated based on the first reflected wave signal collected by the optical fiber sensor distributed at each collection point in the optical fiber composite overhead transmission cable, including: S401, acquiring a plurality of first reflected wave signals collected at different times by optical fiber sensors distributed at various collection points in the optical fiber composite overhead transmission cable; S402, calculating multiple candidate temperature values ​​of each collection point based on multiple first reflected wave signals; S403: Taking an average value of a plurality of candidate temperature values ​​corresponding to each collection point as a first temperature value of each collection point.

[0033] In an embodiment of the present invention, in order to prevent the influence of ambient temperature on the detection results, when determining the initial coverage range of the hardware to be monitored, for the first temperature value of each collection point, it is necessary to collect multiple times and then take the average value. Specifically, after the hardware to be monitored is installed, the first reflected wave signal of each collection point is collected continuously for multiple times, and multiple candidate temperature values ​​of each collection point are calculated based on the multiple first reflected wave signals, and then the average value of the multiple candidate temperature values ​​corresponding to each collection point is calculated, and the average value is used as the first temperature value of the collection point.

[0034] The embodiment of the present invention determines the first temperature value of each collection point by calculating the average value of multiple temperatures of each collection point, which can effectively remove the impression of the ambient temperature and ensure the accuracy of the monitoring result of the hardware to be monitored.

[0035] As a possible implementation mode of the present invention, in this implementation mode, determining the initial coverage range of the hardware to be monitored based on the position and number of the collection points covered by the hardware includes: The range of the optical fiber composite overhead power transmission cable covered by the hardware coverage collection point is determined as the initial coverage range of the hardware to be monitored.

[0036] In an embodiment of the present invention, after determining the collection points covered by the fittings, the initial coverage range of the fittings to be monitored is determined based on the positions of the collection points covered by the fittings on the optical fiber composite overhead power transmission cable. As in the previous embodiment, the range of the optical fiber composite overhead power transmission cable between the 3rd to 14th collection points can be determined as the initial coverage range.

[0037] As a possible implementation mode of the present invention, in this implementation mode, Figure 5 As shown, the real-time coverage range of the hardware to be monitored is calculated based on the second reflected wave signal collected by the optical fiber sensor at each collection point within the range to be monitored in the optical fiber composite overhead transmission cable, including: S501, calculating a second temperature value of each collection point within the range to be monitored based on a second reflected wave signal collected by the optical fiber sensor at each collection point within the range to be monitored; S502, determining the position of the optical fiber composite overhead power transmission cable covered by a second number of consecutive collection points within the monitoring range as the real-time coverage range of the hardware to be monitored, wherein the second temperature values ​​of the second number of consecutive collection points are all greater than the preset temperature threshold, and the second number is greater than the preset number threshold.

[0038] In the embodiment of the present invention, similar to the above-mentioned embodiment, the second temperature value of each collection point in the monitoring range can be calculated based on the second reflected wave signal collected by the optical fiber sensor of each collection point in the monitoring range, and then the real-time coverage range of the hardware to be monitored is determined based on the second temperature value. Similarly, the temperature of each collection point in the real-time coverage range should reach a preset temperature threshold, and the number of collection points in the real-time coverage range should be greater than the preset number threshold. The specific calculation method of the temperature value and the specific determination scheme of the real-time coverage range are the same as the initial coverage range in the above-mentioned embodiment, and will not be repeated here.

[0039] The embodiment of the present invention calculates the second temperature value of the collection point within the range to be monitored, and determines the real-time coverage range of the hardware to be monitored based on the second temperature value, so as to facilitate the subsequent confirmation of abnormal conditions of the hardware to be monitored.

[0040] As a possible implementation mode of the present invention, in this implementation mode, Figure 6 As shown, whether the hardware to be monitored is abnormal is determined based on the relationship between the initial coverage and the real-time coverage, including: S601, constructing a first temperature curve of the initial coverage range based on the first temperature value of each collection point within the initial coverage range; constructing a second temperature curve of the real-time coverage range based on the second temperature value of each collection point within the real-time coverage range; S602, when a displacement deviation occurs between the first temperature curve and the second temperature curve, it is determined that the hardware to be monitored has an abnormal displacement; S603: When the number of collection points covered by the initial coverage range and the number of collection points covered by the real-time coverage range are different, it is determined that the hardware to be monitored has abnormal deformation.

[0041] In the embodiment of the present invention, the first temperature curve refers to a curve reflecting the corresponding relationship between the first temperature value of each collection point and the position of each collection point on the optical fiber composite overhead power transmission cable within the initial coverage range, and the second temperature curve refers to a curve reflecting the corresponding relationship between the second temperature value of each collection point and the position of each collection point on the optical fiber composite overhead power transmission cable within the real-time coverage range. The translation relationship between the first temperature curve and the second temperature curve can be calculated using a preset calculation formula. Specifically, the calculation formula is as follows:

[0042] in, Indicates the first temperature curve iThe first temperature value of the collection point, Indicates the second temperature curve corresponding to the first temperature curve i Collection point translation d collection points, among which d A positive number means a rightward shift. d A negative number means shifting to the left. n Indicates the number of acquisition points shared by the first temperature curve and the second temperature curve, is the displacement judgment value. When the displacement judgment value is the largest, it means that the first temperature curve and the second temperature curve overlap best at this time. d The value of can be used to determine whether the hardware to be monitored has moved. Specifically, when the displacement judgment value is calculated At maximum, d The value of is 2, which means that the hardware to be monitored has moved two collection points to the right. d If it is -3, it means that the hardware to be monitored has shifted 3 collection points to the left. d If it is 0, it means that the hardware to be monitored has not been displaced. Further, when the hardware to be monitored is displaced, the displacement distance of the hardware to be monitored can be determined based on the number of displacement collection points and the interval distance between each collection point.

[0043] In the embodiment of the present invention, further, it can be determined whether the hardware to be monitored is deformed based on the number of collection points included in the initial coverage range and the real-time coverage range. Generally, the hardware to be monitored is elongated when it is deformed, that is, when the number of collection points included in the real-time coverage range is greater than the number of collection points included in the initial coverage range, it can be determined that the hardware to be monitored is elongated. Similarly, the length of the elongated hardware to be monitored can be determined based on the number of extra collection points and the spacing between the collection points.

[0044] The embodiment of the present invention determines whether the hardware to be monitored is displaced by the first temperature curve and the second temperature curve, and determines whether the hardware to be monitored is deformed by the number of collection points within the initial coverage range and the real-time coverage range, so as to accurately and timely monitor the abnormal displacement and deformation of the hardware.

[0045] As a possible implementation mode of the present invention, in this implementation mode, after determining whether the hardware to be monitored is abnormal, the method includes: When an abnormality occurs in the hardware to be monitored, early warning information is generated based on the abnormality type, and the early warning information is used to indicate the abnormality type of the hardware to be monitored.

[0046] In an embodiment of the present invention, when the change in the position or length of the hardware exceeds a preset safety threshold, the early warning mechanism can be automatically triggered and an early warning message can be issued. The early warning information is used to indicate the abnormal type of the hardware to be monitored. Furthermore, the early warning information may include the specific position of the hardware, the time when the abnormality occurred, the type of abnormality (such as looseness, displacement or deformation) and the degree of abnormality. In order to improve the accuracy and timeliness of fault warning, a multi-level alarm mechanism can be set. When the abnormal condition of the hardware further deteriorates and exceeds a higher safety threshold, the system will upgrade the early warning to an alarm state, send out a more urgent alarm signal, and mark it on the display terminal of the monitoring center to remind maintenance personnel to take immediate maintenance measures.

[0047] In order to better implement the hardware monitoring method in the embodiment of the present invention, based on the hardware monitoring method, correspondingly, Figure 7 As shown, the embodiment of the present invention further provides a hardware monitoring device, and the hardware monitoring device 700 includes: The initial coverage range calculation module 701 is used to determine the initial coverage range of the hardware to be monitored based on the first reflected wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead power transmission cable; The real-time coverage range calculation module 702 is used to calculate the real-time coverage range of the hardware to be monitored based on the second reflected wave signal collected by the optical fiber sensor at each collection point within the range to be monitored in the optical fiber composite overhead transmission cable; the range to be monitored includes the initial coverage range and the preset range before and after the initial coverage range; The abnormality monitoring module 703 is used to determine that an abnormality occurs in the hardware to be monitored when the initial coverage range and the real-time coverage range do not overlap.
