This has brought many problems such as identification, management, monitoring, and fault location. There is an urgent need for an effective operation status perception method to ensure the normal progress of intelligent monitoring, so as to ensure the stable and reliable operation of the power fiber communication network.

[0003] However, the existing intelligent perception methods for the operation status of optical fibers use sensors or manual detection methods to obtain the operation data of optical fibers.

[0049] Figure 3 is a structural block diagram of a method for perceiving the operation state of a power optical cable in Embodiment 3 of the present invention. Detailed Embodiments

[0050] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of description, only parts related to the present invention are shown in the drawings rather than all the structures.

[0051] Embodiment 1

[0052] Figure 1The figure is a flowchart of a method for perceiving the operation status of a power optical cable provided in Embodiment 1 of the present invention. This embodiment is applicable to a method for detecting a large amount of optical fiber link data and analyzing the detection results in a power system. This method can be executed by an operation status perception device of a power optical cable. The device includes a locator, a sensor, and a server. Refer to Figure 1 , and specifically includes the following steps:

[0053] Step 110: The server controls the locator to segment and locate the optical fiber link to be measured according to a preset segmentation rule, and assigns a unique identity code to each segment of the optical fiber link;

[0054] Since the optical fiber link transmits communication information between different devices, due to different device spacings, the lengths of the optical fiber links vary greatly. To avoid accidents during transmission due to overly long optical fiber links, it is necessary to view long-distance optical fiber links in segments. Therefore, the server controls the locator to segment and locate the optical fiber link to be measured according to a preset segmentation rule.

[0055] Among them, the preset segmentation rule refers to segmenting according to the length or distance of the optical fiber link. Exemplarily, assuming that the length of the optical fiber link exceeds 50 meters, the optical fiber link is segmented with 50 meters as the segmentation unit. It should be noted that the specific segmentation length can be set according to the actual situation and is not specifically limited here.

[0056] Among them, the locator can be a cable fault locator.

[0057] Specifically, after the server controls the locator to segment the optical fiber link to be measured according to the preset segmentation rule, the locator encodes each segment of the optical fiber link according to the actual position of the optical fiber link to be measured and the name of the component to which the optical fiber link is connected. Since the position of each segment of the optical fiber link is different, each identity code is unique. The server can obtain the actual position information of the optical fiber link corresponding to the optical fiber link segment and the name information of the component to which it is connected by obtaining the identity code information. Therefore, the server can realize segmenting and locating the optical fiber link to be measured by controlling the locator according to the preset segmentation rule.

[0058] Step 120: Obtain the historical fault information of the optical fiber link to be measured;

[0059] Among them, through the historical fault information of the optical fiber link to be measured, information such as the position information where the optical fiber link is prone to failure, the information of the connection components prone to failure, the types of faults prone to occur, and the positions where each type of fault occurs frequently in the optical fiber link can be obtained.

[0060] Step 130: Determine the distribution positions of the sensors according to the historical fault information of the optical fiber link to be measured and the identity codes of each section of optical fiber;

[0061] Among them, the sensors are used to collect the operation status information of the optical fiber link at the corresponding arranged positions to monitor the fault conditions of the optical fiber link at the corresponding positions. In order to improve the efficiency of monitoring the optical fiber link and avoid a large amount of useless monitoring data, it is necessary to reasonably arrange the positions of the sensors. Moreover, since the optical fiber link has a relatively long line and many complex lines, in order to improve the effectiveness of monitoring, the positions of the sensors can be arranged based on the historical fault conditions of the optical fiber link to be measured, and the sensors are arranged within the historical fault range. Thus, while ensuring the effectiveness of monitoring, the monitoring range can be reduced, the data acquisition volume can be decreased, a large amount of useless data can be avoided, the burden on the system can be reduced, and the availability of data acquisition and the efficiency of monitoring can be improved.

[0062] Among them, according to the identity codes of each section of optical fiber, the actual arranged positions of the sensors can be accurately located, so that the operation status information collected by the sensors after the positions are determined can be obtained corresponding to which section of the optical fiber link, and thus the efficiency of monitoring the optical fiber link can be improved.

[0063] Among them, the sensor can be the optical fiber link itself. Because the optical fiber material has photosensitivity, ultraviolet light is written into the core of the optical fiber to form an optical reflection wave in the core, and a fiber physical identification code is implanted in each end of the optical fiber link to realize the unique identity code for the connection of each section of optical fiber.

[0064] Step 140: After the distribution positions of the sensors are determined, obtain the operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors, and screen the operation status information to obtain the operation status change information of the optical fiber link to be measured.

[0065] Among them, after the distribution positions of the sensors are determined, the sensors at each distribution position collect the operation status information of the optical fiber link at their respective corresponding positions and send it to the server. The server screens and processes the operation status information of the optical fiber link at each distribution position, so as to obtain the change situation of the operation status of the optical fiber link to be measured, and realize the intelligent perception and monitoring of the operation status of the optical fiber link.

[0066] In the technical solution of this embodiment, the working principle of the operation status perception method for the power optical cable is as follows: First, the server controls the locator to segment and locate the optical fiber link to be measured according to the preset segmentation rule, and assigns a unique identity code to each segment of the optical fiber link; obtains the historical fault information of the optical fiber link to be measured; determines the distribution positions of the sensors according to the historical fault information of the optical fiber link to be measured and the identity code of each segment of the optical fiber; after the distribution positions of the sensors are determined, obtains the operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors, and screens the operation status information to obtain the operation status change information of the optical fiber link to be measured. Thus, the distribution positions of the sensors are determined according to the historical fault information of the optical fiber link to be measured and the identity code of each segment of the optical fiber. The optical fiber link segments that need to be monitored and collected can be determined through the historical fault situation, avoiding useless data and duplicate data, improving the availability and effectiveness of data collection, reducing the data collection volume, reducing the system burden, improving the efficiency of monitoring the optical fiber link, and at the same time, the position of the sensor can be accurately located through the identity code of the optical fiber link, which can further improve the efficiency of monitoring the optical fiber link. In addition, after the distribution positions of the sensors are determined, the operation status information of the optical fiber collected by the sensors at each distribution position is obtained, and the operation status information is screened to obtain the operation status change information of the optical fiber link to be measured, so as to realize the intelligent perception of the operation status information of the optical fiber link, and further ensure the effective monitoring of the operation status of the optical fiber link.

[0067] Embodiment 2

[0068] Figure 2 is a flowchart of an operation status perception method for a power optical cable provided in Embodiment 2 of the present invention. On the basis of the above Embodiment 1, optionally, referring to Figure 2 , the operation status perception method for the power optical cable specifically includes the following steps:

[0069] Step 210: The server controls the locator to segment and locate the optical fiber link to be measured according to the preset segmentation rule, and assigns a unique identity code to each segment of the optical fiber link;

[0070] Step 220: Obtain the historical fault information of the optical fiber link to be measured;

[0071] Step 230: Arrange the initial positions of the sensors according to the historical fault information of the optical fiber link to be measured;

[0072] Among them, the sensor is used to collect the operation status information of the optical fiber link at the corresponding arrangement position to monitor the fault condition of the optical fiber link at the corresponding position. In order to improve the efficiency of monitoring the optical fiber link and avoid a large amount of useless monitoring data, it is necessary to reasonably arrange the positions of the sensors. Therefore, based on the historical fault conditions of the optical fiber link to be measured, the initial position arrangement of the sensors can be carried out to achieve a rough arrangement of the sensors.

[0073] Step 240: Calculate the fault detection rate under the initial position arrangement.

[0074] Among them, the sensor is used to collect the operation status information of the optical fiber link at the corresponding arrangement position to monitor the fault condition of the optical fiber link at the corresponding position. In order to detect whether the initial position arrangement of the sensor is reasonable, it is necessary to calculate the fault detection rate under the initial position arrangement to ensure that the fault condition of the optical fiber link under the initial position arrangement can be effectively monitored.

[0075] Step 250: If the fault detection rate meets the preset detection rate, the initial position arrangement is reasonable; if the fault detection rate does not meet the preset detection rate, change the initial position arrangement method, and calculate the fault detection rate under the changed arrangement method according to the calculation method of the fault detection rate under the initial position arrangement until the preset detection rate is met.

[0076] Among them, if the fault detection rate meets the preset detection rate, it means that the current arrangement method of the sensor is reasonable and can realize the monitoring of the fault of the optical fiber link to be measured; if it does not meet the preset detection rate, it means that the current arrangement method of the sensor is unreasonable and cannot realize the monitoring of the fault of the optical fiber link to be measured. Among them, the preset detection rate can be, for example, 80%, 82%, 85%, etc., and can be specifically set according to the actual situation, and no specific limitation is made here.

[0077] Specifically, if the fault detection rate of the initial position arrangement of the sensor meets the preset detection rate, it means that the initial position arrangement is reasonable and can realize the monitoring of the fault of the optical fiber link to be measured. If the fault detection rate of the initial position arrangement of the sensor does not meet the preset detection rate, then change the way of the initial position arrangement, and calculate the fault detection rate under the changed arrangement method according to the calculation method of the fault detection rate under the initial position arrangement. If it meets, it means that the changed arrangement method is reasonable. If it does not meet, it means that the changed arrangement method is unreasonable and cannot realize the monitoring of the fault of the optical fiber link to be measured. Then, based on the changed arrangement method, continue to change the arrangement method until its fault detection rate meets the preset detection rate.

[0078] Step 260: After the sensor distribution position is determined, obtain the operation status information of the optical fiber link at the corresponding distribution position collected by the sensor, and screen the operation status information to obtain the operation status change information of the optical fiber link to be measured.

[0079] Optionally, obtain the historical fault information of the optical fiber link to be measured, including: obtaining the historical fault information of each section of the optical fiber link;

[0080] According to the historical fault information of the optical fiber link to be measured, arrange the initial positions of the sensors, including: sorting each section of the optical fiber link in descending order of the frequency of historical faults;

[0081] Select n most fault-prone parts in descending order and arrange a sensor at each part.

[0082] Among them, the historical fault information of the optical fiber link may include the frequency of faults occurring in the optical fiber link. Correspondingly, the historical fault information of each section of the optical fiber link may include the frequency of faults occurring in the corresponding section of the optical fiber link. When arranging the initial positions of the sensors, in order to improve the efficiency of monitoring the optical fiber link and avoid a large amount of useless monitoring data, n most fault-prone parts of the optical fiber link can be selected in descending order of the frequency of historical faults of the optical fiber link as the initial positions for arranging the sensors. For example, according to the historical fault information of each section of the optical fiber link, select 5 most frequently fault-occurring parts in descending order of the frequency of faults, and arrange a sensor at each of these 5 parts. Each sensor is used to collect the operation status information of the optical fiber link at its arranged position and send it to the server.

[0083] Among them, n can also be other values, which can be specifically set according to the actual situation and are not specifically limited here.

[0084] Optionally, the calculation method of the fault detection rate includes:

[0085] Establish a communication transmission model of the sensors;

[0086] Obtain the data information collected by the sensors in the current sensor position arrangement mode;

[0087] According to the communication transmission model of the sensors and the data information collected by the sensors in the current sensor position arrangement mode, calculate the fault detection rate in the current sensor position arrangement mode.

[0088] Among them, in order to verify the rationality of the current sensor position arrangement mode, it is necessary to calculate the fault detection rate in the current sensor position arrangement mode. The fault detection rate is related to the current position arrangement mode of the sensors, the type of faults, the data related to the faults, the data collected by the sensors, etc. Therefore, first establish a communication transmission model of the sensors, then obtain the data information collected by each sensor in the current sensor position arrangement mode, and finally calculate the fault detection rate in the current sensor position arrangement mode according to the communication transmission model of the sensors and the data information collected by the sensors in the current sensor position arrangement mode.

[0089] Optionally, establishing the communication transmission model of the sensor includes: establishing a two-dimensional fault-test correlation matrix model;

[0090] Among them, the two-dimensional fault-test correlation matrix model is:

[0091]

[0092] Among them, i represents the total number of all fault types; p represents the number of sensor arrangements or the number of test points; S represents the set of state data related to faults; T represents the set of data measured by the sensors at the test points;

[0093] Among them, the elements in ST i,p take values of 0 or 1; when the value is 0, it means that when the i-th fault type occurs, the sensors at the p test points cannot detect the i-th fault type; when the value is 1, it means that when the i-th fault type occurs, the sensors at the p test points can detect the i-th fault type.

[0094] Exemplarily, taking the element ST i,1 as an example, when the element ST i,1 takes the value of 0, it means that when the i-th type of fault occurs, the sensor at test point 1 cannot detect the i-th type of fault; when the element ST i,1 takes the value of 1, it means that when the i-th type of fault occurs, the sensor at test point 1 can detect the i-th type of fault. Exemplarily, taking the element ST 1,p as an example, when the element ST 1,p takes the value of 0, it means that when the first type of fault occurs, the sensor at test point p cannot detect the first type of fault; when the element ST 1,p takes the value of 1, it means that when the first type of fault occurs, the sensor at test point p can detect the first type of fault.

[0095] Optionally, according to the communication transmission model of the sensor and the data information collected by the sensors in the current sensor position arrangement, calculating the fault detection rate in the current sensor position arrangement includes:

[0096] Calculating the fault detection rate in the current sensor position arrangement according to the two-dimensional fault-test correlation matrix model and the data information collected by the sensors in the current sensor position arrangement.

[0097] Exemplarily, assume that n sensors are arranged in the current sensor position arrangement mode, that is, n test points are arranged. According to the data information collected at each test point, the values of each element in the matrix are listed in the fault - test two - dimensional correlation matrix, and the value of each element is 0 or 1. For example, ST i,p The value of the element in it is 0 or 1; when the value is 0, it means that when the i - th fault type occurs, the data information collected by the sensor at the p test point cannot detect the i - th fault type; when the value is 1, it means that when the i - th fault type occurs, the data information collected by the sensor at the p test point can detect the i - th fault type. Thus, through the value of each element in the fault - test two - dimensional correlation matrix, the detection situation of the sensors at each test point for various fault types can be obtained, that is, it can be obtained whether each fault type can be detected by the current sensor position arrangement mode, and then the fault detection rate under the current sensor position arrangement mode can be calculated according to the calculation formula of the fault detection rate.

[0098] Optionally, according to the fault - test two - dimensional correlation matrix model and the data information collected by the sensors in the current sensor position arrangement mode, the formula for calculating the fault detection rate in the current sensor position arrangement mode is:

[0099]

[0100] where M is the fault detection rate in the current sensor position arrangement mode; g is the number of fault types that cannot be detected in the current sensor position arrangement mode; i represents the total number of all fault types;

[0101] Among them, in the fault - test two - dimensional correlation matrix model, if at least one column of elements is all 1, the current sensor position arrangement mode is reasonable; if there are row elements all 0, the fault type corresponding to the row cannot be detected by the current sensor position arrangement mode.

[0102] Among them, as long as all fault types can be detected by the sensors under the current sensor position arrangement, it indicates that the fault detection rate under the current sensor position arrangement is 100%, which means the current sensor position arrangement is reasonable. In the fault-test two-dimensional correlation matrix model, the column elements represent the detection situation of a certain test point for all fault types. If there is a column where all elements are 1, it means that this test point can detect all fault types. Then the number of fault types that cannot be detected under the current sensor position arrangement is 0. According to the formula, the fault detection rate under the current sensor position arrangement is 100%, so the current sensor position arrangement is reasonable. For example, assume that the elements in the column where the p-th test point is located all take the value of 1, which means that the p-th test point can detect all i fault types. That is to say, as long as there is at least one test point where the sensor can detect all fault types under the current sensor position arrangement, regardless of whether the sensors at other test points can detect various fault types, it can be concluded that the current sensor position arrangement is reasonable.

[0103] In the fault-test two-dimensional correlation matrix model, the row elements represent the detection situation of a certain fault type by each test point under the current sensor position arrangement. If there is a row where all elements are 0, it means that the fault type corresponding to this row cannot be detected by any test point under the current sensor position arrangement. Let g also represent the number of rows where all elements are 0 in the fault-test two-dimensional correlation matrix. Then, according to the formula of the fault detection rate, the fault detection rate under the current sensor position arrangement can be calculated.

[0104] Optionally, if the fault detection rate does not meet the preset detection rate, change the initial position arrangement, including:

[0105] On the basis of the initial position arrangement, sequentially increase one test point in ascending order, and arrange a sensor at the newly added test point.

[0106] Exemplarily, assume that 5 test points are arranged in the initial position arrangement manner (these 5 test points are selected according to the order of the historical failure occurrence frequencies from high to low). If the fault detection rate of the initial position arrangement manner does not meet the preset detection rate, then based on these 5 test points, a sixth test point is added according to the fault position with the sixth highest frequency in the historical failure occurrence frequencies, and a sensor is arranged at the sixth test point. Then, calculate the fault detection rate of the position arrangement manner of the 6 test points according to the calculation method of the fault detection rate in the initial position arrangement. If it meets the preset detection rate, it is reasonable; if it does not meet, then based on these 6 test points, a seventh test point is added according to the fault position with the seventh highest frequency in the historical failure occurrence frequencies, and a sensor is arranged at the seventh test point. Then, calculate the fault detection rate of the position arrangement manner of the 7 test points according to the calculation method of the fault detection rate in the initial position arrangement, and so on, until the fault detection rate of the position arrangement manner of the sensors meets the preset detection rate, and the position arrangement manner when it meets the preset detection rate is the finally determined distribution position of the sensors.

[0107] It should be noted that by determining the distribution position of the sensors according to the method of the above embodiment, it can be realized that when any type of fault occurs in the optical fiber link, this sensor arrangement manner can detect the fault, so as to be able to monitor the change information of the operation status information of the optical fiber link to be measured, and improve the monitoring efficiency. Thus, by arranging the positions of the sensors, the availability and effectiveness of the perception of the operation status information can be further improved, which is beneficial to improving the monitoring efficiency, can avoid the appearance of a large amount of useless monitoring data, and can reduce the burden on the system.

[0108] Optionally, after the distribution position of the sensors is determined, obtain the operation status information of the optical fiber link at the corresponding distribution position collected by the sensors, and screen the operation status information to obtain the operation status change information of the optical fiber link to be measured, including:

[0109] After the distribution position of the sensors is determined, respectively obtain the operation status information of the optical fiber link at the corresponding distribution position collected by the sensors at the current moment and the previous moment;

[0110] Compare the operation status information of the optical fiber link at the corresponding distribution position collected by the sensors at the current moment with the operation status information of the optical fiber link at the corresponding distribution position collected by the sensors at the previous moment, and calculate the data fluctuation between the two;

[0111] If the data fluctuation exceeds the preset fluctuation range, then screen out the operation status information of the optical fiber link at the corresponding distribution position collected by the sensors at the current moment to obtain the operation status change information of the optical fiber link to be measured.

[0112] Specifically, after the sensor distribution positions are determined, the sensors at each test point collect the operation status information of the optical fiber link at the corresponding positions and send it to the server. To further reduce the amount of system data received, reduce the system burden, and improve work efficiency, after the sensor distribution positions are determined, the collected operation status information is screened in real time to eliminate duplicate data within the same time period, reduce the amount of data received by the system, reduce the system burden, and ensure the rapid progress of the monitoring work.

[0113] Specifically, the operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors at the current moment and the previous moment is obtained respectively. The operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors at the current moment is compared with the operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors at the previous moment, and the data fluctuation between the two is calculated. If the data fluctuation exceeds the preset fluctuation range, it indicates that the data monitored by the sensor is abnormal, and it also indicates that the sensor at the current test point can monitor the fault information of the optical fiber link. Therefore, the operation status information of the optical fiber link at the corresponding distribution positions collected by the sensors at the current moment is screened out and uploaded to the monitoring system, and based on this, the specific location where the optical fiber link at this test point fails can be obtained, so as to determine the change information of the operation status of the optical fiber link to be measured.

[0114] Among them, the preset fluctuation range can be 5%, and the specific value can be set according to the actual situation and will not be specifically limited here.
