Detection for optical cable equipment is usually based on detection equipment such as a traditional Optical Time Domain Reflectometer (OTDR) and the like to detect an optical cable breakpoint on site in an optical cable line maintenance management mode, but because a system comprising optical cable detection consists of multiple parts, the reliability is poor, the response speed to the fault is determined by people, the fault finding is very difficult, and the generation of hidden danger detection cannot be accurately predicted on the basis of long fault removal time on site, so that the normal work of the optical cable is influenced. The embodiment of the invention provides an optical cable equipment abnormity detection method, as shown in fig. 1, the method comprises the following steps:
101. and sending a path determining instruction to each transformer substation, receiving an optical cable transmission target fed back by each transformer substation, and constructing an optical cable topology network through the optical cable transmission target.
In the embodiment of the invention, the current execution main body is a server side which performs data communication with each transformer substation, and can be an optical cable equipment management platform or an optical cable equipment control system, and the like. The optical cable transmission target is an object for data communication transmission through an optical cable, and may be a substation, or other data base stations, terminal equipment, or the like.
It should be noted that, in the embodiment of the present invention, in order to accurately detect whether each optical cable is abnormal in the transmission process, the current execution end constructs an optical cable topology network according to the optical cable transmission target, so as to perform optical cable abnormality detection based on the transmission structure in the network. The optical cable topology network includes at least one optical cable path, where the optical cable path includes size information of an optical cable and transmission characteristic information, so as to determine whether there is an abnormality based on the size information and the transmission characteristic information of each optical cable path, where the transmission characteristic information is used to represent information such as data transmission speed and transmission content, and embodiments of the present invention are not limited specifically.
102. And determining an optical cable scheduling detection strategy according to a preset time interval, and determining an optical cable detection object from the optical cable topology network based on the optical cable scheduling detection strategy.
In the embodiment of the present invention, different optical cable scheduling detection strategies are stored in advance in the current execution end, where the optical cable scheduling detection strategies are used to characterize a method for determining the number of optical cable detection objects and detection characteristics based on size information and transmission characteristic information of different optical cables in the optical cable topology network, that is, determining which optical cable or optical cables are to be detected and how to detect the optical cable detection objects and the transmission characteristics information from the optical cable topology network, for example, the optical cable scheduling detection strategy is to select an optical cable whose size information meets a preset size range from the optical cable topology network and detect the optical cable according to a data transmission speed and a transmission connection line in the optical cable.
It should be noted that, the current execution end uses a preset time interval as a condition for triggering the scheduling detection, where the preset time interval may be 3 days or 5 days, and is used as a trigger time point for determining the optical cable scheduling detection policy.
103. And sending a time domain reflection instruction to a target transformer substation corresponding to the optical cable detection object so as to receive the fed-back optical cable attenuation information.
In the embodiment of the invention, after the current server determines the optical cable detection object, a time domain reflection instruction is sent to the target transformer substation corresponding to the optical cable detection object so as to obtain optical cable attenuation information. In the embodiment of the present invention, each substation is provided with a time domain reflectometer for optical cables, that is, a target substation is configured with corresponding optical time domain reflectometer equipment, for example, an optical time-domain reflectometer (OTDR), so that the time domain reflectometer collects optical cable attenuation information when the substation receives a time domain reflectometer instruction.
104. And acquiring the optical power, the error code parameter and the early warning weight value of the optical cable, and determining whether the optical cable has abnormal detection or not according to the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value to obtain a detection result.
In the embodiment of the invention, after the optical cable attenuation information is obtained, the current server side obtains the optical power, the error code parameter and the early warning weight value of the optical cable, so that the optical cable is subjected to abnormal detection by combining the optical cable attenuation information, and the detection result is obtained.
It should be noted that the optical power is the power of the optical cable during data transmission, the early warning weight value is a probability weight obtained by predicting the optical cable based on a historical detection result based on characterization, and the error code parameter is used for characterizing an abnormal proportion determined based on the hardware loss of the optical cable, so that whether the optical cable has abnormal detection is determined based on the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value.
In another embodiment of the present invention, for further definition and explanation, as shown in fig. 2, the step of constructing a fiber optic topology network through the fiber optic transmission targets includes:
201. analyzing the identity of the transformer substation and the number of optical cable transmission targets which are marked in association with the identity;
202. establishing optical cable paths among the transformer substations according to the identity marks and the optical cable transmission target number;
203. and constructing an optical cable topology network according to the optical cable paths and the cross relationship among the optical cable paths.
In the embodiment of the invention, because the optical cable transmission target is at least one object transmitted by the transformer substation through the optical cable, in order to determine the optical cable to be checked in the constructed optical cable topology network, and thereby improve the accuracy of optical cable detection, when the optical cable topology network is constructed, firstly, the identity of the transformer substation and the number of optical cable transmission targets marked in association with the identity are analyzed. When the current server side is used for data communication in the transformer substation, the identity identification of each transformer substation is pre-identified to determine the identity of the transformer substation, and at the moment, each identity identification can be associated with a plurality of targets which are specified and need to be transmitted through optical cables, for example, the transformer substation s is specified to need to be transmitted through the optical cables with the transformer substation a and the transformer substation b, so that the transformer substation a and the transformer substation b need to be marked and associated with the transformer substation s to determine that the number of the optical cable transmission targets is 2. And then, establishing optical cable paths among all the substations based on the number of the optical cable transmission targets and the corresponding identity.
It should be noted that, since each substation can perform data transmission with multiple or one other substation based on cables, when constructing the optical cable topology network, it is necessary to determine the cross relationship between optical cable paths, and at this time, the cross relationship may be determined based on the geographic location between the substations and whether multiple optical cable paths cross. For example, as shown in fig. 3, the optical cable path 1 is a substation a-a substation s-a substation k-a substation w, and the optical cable path 2 is a substation a-a substation u-a substation e-a substation q, as shown in fig. 3, wherein the substation u, the substation k, and the substation w are located at geographical positions in a row or a region, and therefore, when the optical cable path 1 corresponds to a dotted line path and the optical cable path 2 corresponds to a solid line path, there is a crossing relationship between the optical cables between the substation u and the substation e and the optical cables between the substation k of the substation s, so as to construct an optical cable topology network based on all the crossing relationships and each optical cable path, and record physical size information (e.g., length, optical cable radius, etc.) and transmission characteristic information (e.g., transmission speed, transmission data interval, etc.) of the optical cables in the network, and the embodiments of the present invention are not limited in particular.
In another embodiment of the present invention, for further definition and explanation, the step of determining the optical cable scheduling detection strategy according to the preset time interval includes:
when the optical cable scheduling instruction matched with the preset time interval is triggered, loading an optical cable scheduling detection strategy library;
and matching the optical cable dispatching detection strategy corresponding to the target transformer substation from the optical cable dispatching detection strategy library.
In an embodiment of the present invention, in a specific implementation scenario, in order to determine an optical cable scheduling detection policy more accurately and more effectively, specifically, the current server determines whether the current server is at a time point of a preset time interval, and at this time, an optical cable scheduling instruction triggered according to the time point is preconfigured in the current execution end, so that optical cable detection is performed according to a time dimension. After triggering the optical cable scheduling instruction, the current server loads an optical cable scheduling detection strategy library, and different optical cable scheduling detection strategies are stored in the optical cable scheduling detection strategy library in advance, at this time, because the optical cable scheduling detection strategies are used for representing a method for determining the number of optical cable detection objects and detection characteristics based on size information and transmission characteristic information of different optical cables in the optical cable topology network, different optical cable scheduling detection strategies can be configured based on detection requirements of different optical cables, and the embodiment of the invention is not specifically limited.
It should be noted that, when matching the optical cable scheduling detection strategy corresponding to the target substation from the optical cable scheduling detection strategy library, each optical cable scheduling detection strategy is a method for determining the number of optical cable detection objects and detection characteristics based on size information and transmission characteristic information of different optical cables in the slave optical cable topology network, so that, during matching, each optical cable detection object in the optical cable topology network, that is, an optical cable belonging to each target substation in the optical cable topology network is determined first, and is used as an optical cable detection object and a matched optical cable scheduling detection strategy. For example, the optical cable topology network includes 5 substations, and after determining the optical cables 1, 2, and 3 among the target substations, the optical cable scheduling detection strategy, that is, the optical cable scheduling detection strategy applicable to the size information and the transmission characteristic information in the optical cables 1, 2, and 3 is determined by taking each of the 5 substations as a target substation, so as to determine which optical cables in the optical cables 1, 2, and 3 need to be detected and which characteristics need to be detected based on the strategy.
In another embodiment of the present invention, for further definition and explanation, the step of determining the cable scheduling detection strategy according to the preset time interval includes:
when the optical cable scheduling instruction matched with the preset time interval is triggered, loading an optical cable scheduling detection strategy library;
and acquiring a scheduling clock bound with the optical cable scheduling detection library, and determining an optical cable scheduling detection strategy according to the direction of a scheduling pointer in the scheduling clock.
In an embodiment of the present invention, in a specific implementation scenario, in order to determine an optical cable scheduling detection policy more accurately and more effectively, specifically, the current server determines whether the current server is at a time point of a preset time interval, and at this time, an optical cable scheduling instruction triggered according to the time point is preconfigured in the current execution end, so that optical cable detection is performed according to a time dimension. After triggering the optical cable scheduling instruction, the current server loads an optical cable scheduling detection strategy library, and different optical cable scheduling detection strategies are stored in the optical cable scheduling detection strategy library in advance, at this time, because the optical cable scheduling detection strategies are used for representing a method for determining the number of optical cable detection objects and detection characteristics based on size information and transmission characteristic information of different optical cables in the optical cable topology network, different optical cable scheduling detection strategies can be configured based on detection requirements of different optical cables, and the embodiment of the invention is not specifically limited.
It should be noted that, in the embodiment of the present invention, to achieve the purpose of flexible optical cable detection, when an optical cable scheduling detection strategy is called, a scheduling clock is configured in advance for an optical cable scheduling detection library, each strategy corresponds to one scheduling pointer in the scheduling clock, and the optical cable scheduling detection strategy is determined through the pointer direction. Each scheduling pointer of the clock divides a timing interval according to a preset time interval, the number of the timing time intervals in the clock is the same as the number of strategies in the optical cable scheduling detection strategy library, and the time intervals can be configured based on optical cable detection requirements. For example, the policy library includes 10 policies, the number of time intervals is 10, and each time interval is 1 day (may also be 1 week, 3 days, etc.), and then the clock counts by the pointer, and a turn of the clock is pointed, and then 10 days pass. When the clock hour hand executes the timing direction, the current service end determines the optical cable scheduling detection strategy corresponding to the scheduling pointer direction in the scheduling clock according to the current time, so as to determine the optical cable scheduling detection strategy, and after the scheduling clock finishes one turn of direction, the next turn of timing direction is carried out again. And when the detection in the step 102 is finished, timing pointing is continued, and when the optical cable scheduling detection strategy is determined at the next preset time interval, the corresponding optical cable scheduling detection strategy is pointed again according to the pointer in the scheduling clock, and at the moment, the preset time interval in the step 102 is different from the timing time interval in the scheduling clock, so that flexible optical cable detection can be realized instead of repeatedly executing the same detection mode.
In another embodiment of the present invention, for further limitation and explanation, the step of obtaining the optical power, the error code parameter, and the warning weight value of the optical cable includes:
sending an optical cable data acquisition request to the transformer substation so as to feed back optical power to the transformer substation;
and calling the updated error code parameters and the early warning weight values.
In a specific implementation scenario, since the early warning weight value is a probability weight obtained by predicting the optical cable based on a representation and a historical detection result, and the error code parameter is used for representing an abnormal proportion determined based on the optical cable hardware loss, in order to more accurately detect the optical cable, in the embodiment of the invention, when the optical power, the error code parameter and the early warning weight value are obtained, specifically, an optical cable data obtaining request is firstly sent to the transformer substation so that the transformer substation collects the optical power and then feeds back the optical power. And meanwhile, calling the updated error code parameters and the early warning weight value, wherein the error code parameters are abnormal proportions determined based on the hardware loss of the optical cable, so that the ratio of the service time of the optical cable to the preset service life can be calculated, and the longer the service time is, the larger the error code parameters are. Meanwhile, the early warning weight value is a probability weight obtained by predicting the optical cable based on the historical detection result based on the representation, namely the probability weight obtained by predicting the abnormality of the optical cable based on the historical detection result, and specifically, in the embodiment of the invention, the probability weight is obtained by multiplying the prediction parameter and the historical detection result. The prediction parameter is a value between 0 and 1, the first selection is 0.5, if the detection result is abnormal, 0.1 is increased, if the detection result is normal, 0.05 is decreased, and so on.
In another embodiment of the present invention, for further limitation and description, the step of determining whether there is an abnormal detection on the optical cable according to the optical cable attenuation information, the optical power, the error code parameter, and the early warning weight value, and obtaining a detection result includes:
when the ratio of the error code parameter to the early warning weighted value is matched with a first abnormal detection range, calculating the optical cable attenuation information, the optical power, the error code parameter and a first abnormal evaluation value corresponding to the early warning weighted value based on an abnormal detection formula;
and if the first abnormal evaluation value is matched with a preset first abnormal evaluation range, determining that the optical cable is abnormal.
In the embodiment of the invention, in the process of judging the abnormity of the optical cable, specifically, the ratio between the error code parameter and the early warning weight is judged firstly, then the first abnormity detection range is matched, if the first abnormity detection range is matched, an abnormity detection formula is selected for calculation and sending to judge the abnormity of the optical cable, and therefore, the first abnormity evaluation value corresponding to the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value is further calculated based on the abnormity detection formula.
It should be noted that, when the first anomaly evaluation value matches a preset first anomaly evaluation range, it is determined that the optical cable is anomalous, and at this time, the first anomaly evaluation range is set to be configured based on an optical cable detection requirement, which is not specifically limited in the embodiment of the present invention. In addition, when the first abnormal evaluation value corresponding to the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value is calculated based on the abnormal detection formula, specifically, the abnormal detection formula is
s is optical cable attenuation information, w is an error code parameter, g is optical power, and q is an early warning weight value.
In another embodiment of the present invention, for further limitation and description, the step of determining whether there is an abnormal detection on the optical cable according to the optical cable attenuation information, the optical power, the error code parameter, and the early warning weight value, and obtaining a detection result includes:
when the ratio of the error code parameter to the early warning weight value is matched with a second abnormal detection range, evaluating the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value based on an abnormal detection evaluation model which is trained by the model to obtain a second abnormal evaluation value;
and if the second abnormal evaluation value is matched with a preset second abnormal evaluation range, determining that the optical cable is abnormal.
In the embodiment of the invention, in the process of detecting and judging the abnormality of the optical cable, specifically, the ratio between the error code parameter and the early warning weight is judged firstly, then the ratio is matched with the second abnormality detection range, if the ratio is matched with the second abnormality detection range, an abnormality detection evaluation model based on the completed model training is selected for judgment, and therefore, the second abnormality evaluation value corresponding to the optical cable attenuation information, the optical power, the error code parameter and the early warning weight value is predicted further based on the abnormality detection evaluation model.
The anomaly detection and evaluation model is obtained by training historical optical cable attenuation information, historical optical power, historical error code parameters and historical early warning weight values based on the marked anomaly evaluation value, namely after a model is constructed based on a deep learning model, a neural network, a support vector machine and the like, the model is trained by utilizing the historical optical attenuation information, the historical optical power, the historical error code parameters and the historical early warning weight values marked with the anomaly evaluation value, and therefore the anomaly of the optical cable is evaluated and judged based on the anomaly detection and evaluation model after model training is completed. Furthermore, if the second anomaly evaluation value matches a preset second anomaly evaluation range, it is determined that the optical cable is abnormal, and the second anomaly evaluation range is set to be configured based on the optical cable detection requirement, which is not specifically limited in the embodiment of the present invention.
