Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0048] The descriptions of “first”, “second”, etc. in the embodiments of the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features or implicitly indicating the number of the indicated technical features. Therefore, the technical features limited by “first” and “second” can explicitly or implicitly include at least one of the features.

[0049] In this document, the reference to “embodiments” means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean that all the embodiments refer to the same embodiment, nor are they mutually exclusive or alternative embodiments to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0050] The present application provides a hardware monitoring method, device, electronic device and storage medium, which are described below respectively.

[0051] Figure 1 An embodiment flowchart of a hardware monitoring method provided by the present application is shown in the figure, as shown in the figure, the hardware monitoring method comprises: Figure 1

[0052] S101, determining an initial coverage range of the hardware to be monitored based on a first reflected wave signal collected by the optical fiber sensor distributed at each collection point in the fiber optic composite overhead transmission cable;

[0053] S102, calculating a real-time coverage range of the hardware to be monitored based on a second reflected wave signal collected by the optical fiber sensor of each collection point in the monitoring range of the fiber optic composite overhead transmission cable; the monitoring range includes the initial coverage range and the preset range before and after the initial coverage range; ​

[0054] 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.

[0055] The embodiment of the present invention provides a method for monitoring abnormalities of pre-twisted fittings of optical fiber composite overhead transmission cables, such as Figure 2 As shown, a possible implementation scenario of an embodiment of the present invention is that sensing optical fibers are pre-distributed in the optical fiber composite overhead transmission cable, and optical fiber sensors are embedded in the sensing optical fibers. The sensing optical fibers are 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 smaller 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 change 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 change of the optical fiber sensing signal in real time.

[0056] 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 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 transmission cable. The specific calculation method will be described in detail in subsequent embodiments of the present invention.

[0057] In an embodiment of the present invention, the range to be monitored in the optical fiber composite overhead 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 the initial coverage range. 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 transmission cable and has been in operation for a period of time. The real-time coverage range may be the same as the initial coverage range or different from the initial coverage range.

[0058] 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 and the real-time coverage range are exactly the same, 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.

[0059] The utility model provides a gold utensil monitoring method, based on the first reflection wave signal of optical fiber sensor collection of distribution in each collection point of optical fiber composite overhead transmission line cable determines the initial coverage range of the gold utensil to be monitored, based on the initial coverage range determines the range to be monitored in optical fiber composite overhead transmission line cable, based on the second reflection wave signal of each collection point collection in the range to be monitored calculates the real -time coverage range of the gold utensil to be monitored, through the relation between initial coverage range and real -time coverage range, determines whether the gold utensil to be monitored has the exception, through the information of sensor ceaselessly obtains, and to the information carries out the analysis, can first time discover the exception of the gold utensil to be monitored, and the abnormal monitoring of the gold utensil to be monitored is more accurate and timely.

[0060] As a possible embodiment of the utility model, in the embodiment, as shown in Figure 3 The initial coverage range to be monitored is determined based on the first reflection wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead transmission line cable, including:

[0061] S301, the first temperature value of each collection point is calculated based on the first reflection wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead transmission line cable;

[0062] S302, the first number of consecutive collection points with a first temperature value greater than a preset temperature threshold are determined as gold utensil coverage collection points; the first number is greater than a preset number threshold;

[0063] S303, the initial coverage range of the gold utensil to be monitored is determined based on the gold utensil coverage collection points.

[0064] In the embodiment of the utility model, since the reflection wavelength change 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 of the reflection wavelength, and therefore, the first temperature value of each collection point can be calculated based on the first reflection wave signal collected by the optical fiber sensors distributed at each collection point in the optical fiber composite overhead transmission line cable.

[0065] In the embodiment of the present application, the covered-golden-fitting collection point refers to a collection point covered by a golden fitting in the fiber composite overhead transmission cable. Due to the coverage of the golden fitting on the fiber composite overhead transmission cable, the temperature of the collection point in the coverage of the golden fitting is obviously higher than the temperature of other parts, and therefore the covered-golden-fitting collection point 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 application, in order to prevent the influence of abnormal data on the monitoring result, it is necessary to ensure that the first temperature values of more than the preset number of first number of consecutive collection points are greater than the preset temperature threshold. For the convenience of description, taking a specific embodiment as an example, it is assumed that the length of the fiber composite overhead transmission cable is 1.6 meters, an optical fiber sensor is arranged every 10 centimeters, a total of 16 collection points are arranged, and the first temperature values of the collection points calculated by the optical fiber sensor collecting the emission wave signals of the collection points are respectively 24.8℃, 24.9℃, 25.3℃, 25.6℃, 25.8℃, 26.1℃, 26.6℃, 26.8℃, 27.0℃, 26.8℃, 26.6℃, 26.1℃, 25.8℃, 25.6℃, 24.9℃, and 24.8℃. Among them, the preset temperature threshold is 25℃, and it can be known that the temperature values of the third to fourteenth collection points are greater than the preset temperature threshold, indicating that the third to fourteenth collection points are covered-golden-fitting collection points, and therefore the range of the fiber composite overhead transmission cable where the third to fourteenth collection points are located is determined as the initial coverage range.

[0066] The embodiment of the present application determines the initial coverage range of the golden fitting to be monitored by the temperature of the collection point, which is convenient for subsequent determination of the monitoring range and monitoring of the state of the golden fitting.

[0067] As a possible implementation manner of the present application, in this implementation manner, as shown in the figure, Figure 4 the first temperature value of each collection point is calculated based on the first reflection wave signal collected by the optical fiber sensor distributed in each collection point of the fiber composite overhead transmission cable, which comprises:

[0068] S401, acquiring a plurality of first reflection wave signals collected by the optical fiber sensor distributed in each collection point of the fiber composite overhead transmission cable at different time;

[0069] S402, calculating a plurality of candidate temperature values of each collection point based on the plurality of first reflection wave signals;

[0070] S403, taking the average value of the plurality of candidate temperature values corresponding to each collection point as the first temperature value of each collection point.

[0071] In the embodiment of the present application, in order to prevent the influence of the ambient temperature on the detection result, when determining the initial coverage range of the to-be-monitored fitting, the first temperature value of each collection point needs to be averaged after multiple collections, specifically, after the to-be-monitored fitting is installed, the first reflected wave signal of each collection point is collected continuously for multiple times, a plurality of candidate temperature values of each collection point are calculated based on the plurality of first reflected wave signals, and the average value of the plurality of candidate temperature values corresponding to each collection point is calculated, and the average value is taken as the first temperature value of the collection point.

[0072] In the embodiment of the present application, the first temperature value of each collection point is determined by calculating the average value of the multiple temperatures of each collection point, which can effectively remove the influence of the ambient temperature and ensure the accuracy of the monitoring result of the to-be-monitored fitting.

[0073] As a possible implementation manner of the present application, in the implementation manner, the initial coverage range of the to-be-monitored fitting is determined based on the position and quantity of the fitting coverage collection points, and includes:

[0074] The range of the optical fiber composite overhead transmission cable covered by the fitting coverage collection points is determined as the initial coverage range of the to-be-monitored fitting.

[0075] In the embodiment of the present application, after the fitting coverage collection points are determined, the initial coverage range of the to-be-monitored fitting is determined based on the position of each fitting coverage collection point in the optical fiber composite overhead transmission cable, and as in the previous embodiment, the range of the optical fiber composite overhead transmission cable between the third to fourteenth collection points can be determined as the initial coverage range.

[0076] As a possible implementation manner of the present application, in the implementation manner, as shown in Figure 5 The real-time coverage range of the to-be-monitored fitting is calculated based on the second reflected wave signal collected by the optical fiber sensor of each collection point in the to-be-monitored range, and includes:

[0077] S501, the second temperature value of each collection point in the to-be-monitored range is calculated based on the second reflected wave signal collected by the optical fiber sensor of each collection point in the to-be-monitored range;

[0078] S502, the position of the optical fiber composite overhead transmission cable covered by the second quantity of continuous collection points in the to-be-monitored range is determined as the real-time coverage range of the to-be-monitored fitting, wherein the second temperature value of the second quantity of continuous collection points is greater than the preset temperature threshold, and the second quantity is greater than the preset quantity threshold.

[0079] In the embodiment of the present application, similar to the foregoing embodiment, the second temperature values of the collection points in the to-be-monitored range can be calculated based on the second reflected wave signals collected by the optical fiber sensors of the collection points in the to-be-monitored range, and then the real-time coverage range of the to-be-monitored fitting is determined based on the second temperature values. Similarly, the temperatures of the collection points in the real-time coverage range should reach the preset temperature threshold, and the number of the collection points in the real-time coverage range should be greater than the preset number threshold. The specific calculation method of the temperature values and the specific determination scheme of the real-time coverage range are the same as those in the initial coverage range in the foregoing embodiment, and will not be described here.

[0080] In the embodiment of the present application, the second temperature values of the collection points in the to-be-monitored range are calculated, and the real-time coverage range of the to-be-monitored fitting is determined based on the second temperature values, so as to facilitate the subsequent confirmation of abnormal conditions of the to-be-monitored fitting.

[0081] As a possible implementation manner of the present application, in this implementation manner, as shown in FIG. 6, the determination of whether the to-be-monitored fitting is abnormal based on the relationship between the initial coverage range and the real-time coverage range includes: Figure 6

[0082] S601, a first temperature curve of the initial coverage range is constructed based on the first temperature values of the collection points in the initial coverage range, and a second temperature curve of the real-time coverage range is constructed based on the second temperature values of the collection points in the real-time coverage range;

[0083] S602, when the first temperature curve and the second temperature curve appear displacement deviation, it is determined that the to-be-monitored fitting occurs displacement abnormality.

[0084] S603, when the number of the collection points covered by the initial coverage range and the real-time coverage range is different, it is determined that the to-be-monitored fitting occurs deformation abnormality.

[0085] In the embodiment of the present application, the first temperature curve refers to the curve of the initial coverage range, which reflects the corresponding relationship between the first temperature values of the collection points and the positions of the collection points on the fiber composite overhead transmission cable, and the second temperature curve refers to the curve of the real-time coverage range, which reflects the corresponding relationship between the second temperature values of the collection points and the positions of the collection points on the fiber composite overhead transmission cable. The translation relationship between the first temperature curve and the second temperature curve can be calculated by using a preset calculation formula. Specifically, the calculation formula is as follows:

[0086]

[0087] wherein, T (i) represents the first temperature value of the i th collection point in the first temperature curve, i T (i+ j) represents the second temperature value of the collection point corresponding to the i th collection point in the first temperature curve in the second temperature curve, j represents the translation distance of the collection point in the second temperature curve corresponding to the i th collection point in the first temperature curve, i j represents the translation distance of the collection point in the second temperature curve corresponding to the i th collection point in the first temperature curve, d ​a collection point, wherein, d is positive, representing rightward translation, d is negative, representing leftward translation, n represents the number of collection points shared by the first temperature curve and the second temperature curve, is a displacement judgment value, when the displacement judgment value is maximum, it indicates that the first temperature curve and the second temperature curve coincide best at this time, and based on the value of d at this time, it can be judged whether the monitoring gold has displacement. Specifically, when the displacement judgment value is maximum, d the value of is 2, indicating that the monitoring gold has translated rightward by two collection points, if d is -3 at this time, it indicates that the monitoring gold has translated leftward by 3 collection points, if d is 0 at this time, it indicates that the monitoring gold has no displacement. Further, when the monitoring gold has displacement, the displacement distance of the monitoring gold can be determined based on the number of displacement collection points and the interval distance between each collection point.

[0088] In the embodiment of the present application, further, the number of collection points contained in the initial coverage range and the real-time coverage range can be used to determine whether the monitoring gold has deformation. Generally, when the monitoring gold has deformation, it is elongated, that is, when the number of collection points contained in the real-time coverage range is greater than the number of collection points contained in the initial coverage range, it can be determined that the monitoring gold is elongated. Similarly, the length of the elongated monitoring gold can be determined based on the number of extra collection points and the interval distance between each collection point.

[0089] The embodiment of the present application can accurately and timely monitor the displacement and deformation abnormalities of the gold by judging whether the monitoring gold has displacement through the first temperature curve and the second temperature curve, and judging whether the monitoring gold has deformation through the number of collection points in the initial coverage range and the real-time coverage range.

[0090] As a possible implementation manner of the present application, after determining whether the monitoring gold is abnormal, it includes:

[0091] When the monitoring gold has abnormality, the pre-warning information is produced based on the abnormal type, and the pre-warning information is used to indicate the abnormal type of the monitoring gold.

[0092] In the embodiment of the present application, when the change of the fitting position or length exceeds the preset safety threshold, the early warning mechanism can be automatically triggered to issue a warning information, and the warning information is used to indicate the abnormal type of the fitting to be monitored. Further, the warning information can include the specific position of the fitting, the time of the abnormality, the abnormal type (such as loosening, displacement or deformation) and the abnormal degree. In order to improve the accuracy and timeliness of fault warning, a multi-level alarm mechanism can be set. When the abnormality of the fitting is further deteriorated and exceeds a higher safety threshold, the system will upgrade the warning to an alarm state, issue a more urgent alarm signal, and mark the display terminal in the monitoring center to remind the maintenance personnel to take immediate maintenance measures.

[0093] In order to better implement the fitting monitoring method in the embodiment of the present application, on the basis of the fitting monitoring method, as shown in Figure 7 The present application also provides a fitting monitoring device, which comprises:

The monitoring range includes the initial coverage range and the preset ranges before and after the initial coverage range.

[0096] An abnormality monitoring module 703 is configured to determine that the fitting to be monitored has an abnormality when the initial coverage range and the real-time coverage range do not coincide.
