Example 1:
fig. 1 shows a flowchart of an implementation of a method for troubleshooting a line fault of an OTN network according to an embodiment of the present invention, and for convenience of description, only a part related to the embodiment of the present invention is shown, and details are as follows:
as shown in fig. 1, a line troubleshooting method of an OTN network provided in an embodiment of the present invention includes the following steps:
s101: and acquiring basic parameters of each OTN device in the OTN, evaluating each basic parameter and determining whether abnormal parameters exist.
The flow main body in this embodiment may be a terminal device, or may be a server, and the following description is given by taking the terminal device as an example in this embodiment. The method comprises the steps that terminal equipment obtains basic parameters of each OTN device in the OTN network, wherein the basic parameters comprise operation parameters and maintenance parameters, and the operation parameters can comprise Optical Transmission Section (OTS) optical power, line side (OCH) optical power, error codes, unavailable time, client side (OAC) optical power, optical monitoring unit communication quality, single plate temperature, fan rotating speed and the like. The overhaul parameters may include commissioning time, fault type, number of faults corresponding to the fault type, and rework completion time.
In this embodiment, the abnormal parameter is a parameter that is obviously different from the conventional parameter and may have a fault, and by acquiring the basic parameter of the OTN device and identifying the abnormal parameter, it may be determined whether the OTN transport network is operating normally.
S102: and if the abnormal parameters exist, determining the range of the fault line according to the abnormal parameters and the corresponding OTN equipment.
In this embodiment, the abnormal parameter is a parameter with a hidden fault risk, if the abnormal parameter exists, the OTN device corresponding to the abnormal parameter is determined first to obtain a line range corresponding to the OTN device, and then the fault line range is determined according to the type of the abnormal parameter, for example, if the abnormal parameter is the line side optical power, it may be determined that a problem occurs at the line side in the line range corresponding to the OTN device, so as to determine the fault line range.
S103: and determining a troubleshooting path according to the range of the faulty line, and searching the line section with the fault according to the troubleshooting path.
In this embodiment, the line segments between each node of the OTN network are provided with numbers, the troubleshooting path includes line segment numbers arranged according to a troubleshooting sequence, and the line segment with hidden trouble can be quickly found according to the troubleshooting path.
As can be seen from the above embodiments, the present invention first obtains the basic parameters of each OTN device in the OTN network, and evaluates each basic parameter to determine whether there is an abnormal parameter; if the abnormal parameters exist, determining the range of the fault line according to the abnormal parameters and the corresponding OTN equipment; and determining a troubleshooting path according to the range of the faulty line, and searching the line section with the fault according to the troubleshooting path. The embodiment of the invention can automatically carry out fault troubleshooting on the line section in the line fault range when the basic parameters of the OTN equipment have faults, thereby being capable of rapidly finding out the fault occurrence position, improving the fault troubleshooting working efficiency and ensuring the safe and stable operation of the OTN transmission network.
As shown in fig. 2, in an embodiment of the present invention, the basic parameters include operation parameters and overhaul parameters, and the abnormal parameters include fault parameters and hidden danger parameters; fig. 2 shows a specific implementation flow of S101 in fig. 1, and the process thereof is detailed as follows:
s201: comparing a first operating parameter of a first OTN device with a corresponding parameter range, wherein the first OTN device is any OTN device of the OTN network, the first operating parameter is any operating parameter of the first OTN device, the parameter range comprises a first parameter range and a second parameter range, and the first parameter range is larger than the second parameter range.
S202: and if the first operation parameter exceeds a first parameter range, determining the first operation parameter as a fault parameter.
S203: and if the first operation parameter is within the first parameter range and exceeds the second parameter range, determining whether the first operation parameter is a hidden danger parameter according to the first operation parameter and the overhaul parameter.
In this embodiment, the first parameter range and the second parameter range corresponding to each operating parameter may be pre-stored in the terminal device, or the first parameter range and the second parameter range may be stored in a higher-level server, when parameter comparison is required, a parameter query request is sent to the server, and the server returns the first parameter range and the second parameter range of each operating parameter. The terminal equipment compares whether the first operation parameter is in a first parameter range, if the first operation parameter is in the first parameter range, the line range corresponding to the OTN equipment is not obviously faulted, whether the first operation parameter is in a second parameter range is judged, if the first operation parameter is in the second parameter range, the first operation parameter is normal, if the first operation parameter is not in the second parameter range, the first operation parameter is faulted, the first operation parameter needs to be further checked by referring to the overhaul parameter, and whether the first operation parameter is a hidden trouble parameter is determined. And if the first operating parameter is not in the first parameter range, taking the first operating parameter as a fault parameter.
As shown in fig. 3, in an embodiment of the present invention, after S101 in fig. 1, the method for troubleshooting a line fault of an OTN network provided in this embodiment further includes:
s301: if the basic parameters of the first OTN device do not have abnormal parameters, determining that the parameter acquisition frequency of the first OTN device is a first frequency;
s302: and if the hidden danger parameters exist in the basic parameters of the first OTN equipment, determining that the parameter acquisition frequency of the first OTN equipment is a second frequency.
In this embodiment, the basic parameters may be divided into normal parameters, fault parameters, and hidden danger parameters through the steps in fig. 2, so that the frequency of obtaining the basic parameters may be determined according to the types of the basic parameters, if the basic parameters are all normal parameters, a lower parameter obtaining frequency may be set, and if hidden danger parameters exist, the change trend of the parameters needs to be closely paid attention to prevent an accident, so that the second frequency is greater than the first frequency.
In this embodiment, the parameter obtaining frequency of the hidden danger parameter can be changed independently, and the parameter obtaining frequency of other unproblematic parameters remains unchanged, so that the workload of the terminal device is reduced, and the data processing time of the terminal device is shortened.
As shown in fig. 4, in one embodiment of the invention, the service parameter includes a commissioning time; fig. 4 shows a specific implementation flow of S203 in fig. 2, and the process thereof is detailed as follows:
s401: and acquiring historical operating parameters corresponding to the first operating parameters, and determining predicted operating parameters in a future preset time period according to the historical operating parameters and the first operating parameters.
In this embodiment, after the first operation parameter is determined to be the hidden danger parameter, the historical operation parameter of the first operation parameter is obtained, so that a graph is fitted according to the historical operation parameter and the current first operation parameter, the trend change of the first operation parameter is determined, the predicted operation parameter of a period of time in the future is determined according to the graph obtained by fitting, and the preset time period may be set to 30 minutes, one hour or one day.
S402: and judging whether the predicted operation parameters exceeding the first parameter range exist in the preset time period.
S403: and if the predicted operation parameters exceeding the first parameter range exist, judging whether the commissioning time exceeds a first time threshold value.
S404: and if the commissioning time exceeds the first time threshold, determining that the first operation parameter is a hidden danger parameter.
In this embodiment, since the first operating parameter does not exceed the first parameter range, it may be determined that the line corresponding to the first operating parameter has not failed, but the first operating parameter exceeds the second parameter range, which indicates that the parameter value is abnormal, so that attention needs to be paid to the operating parameter to prevent the line failure. And with the increase of the commissioning time, the probability of the fault of the OTN device also increases, so that the commissioning time can be used as a judgment standard for judging whether the first running time is a hidden danger parameter. And if parameters exceeding the first parameter range exist in the predicted operation parameters and the commissioning time exceeds a first time threshold, determining the first operation parameters as hidden danger parameters.
Further, when the commissioning time does not exceed the first time threshold, determining that the first operation parameter is a sub-health parameter, recording the sub-health parameter, and if the continuous preset times of the first operation parameter acquired by the terminal device are all sub-health parameters, determining that the first operation parameter is a hidden danger parameter.
Furthermore, the overhaul parameters further comprise repair completion time, when the overhaul is completed, overhaul completion time is recorded by an overhaul worker, the overhaul completion time is determined by the terminal device according to the overhaul completion time, and when the overhaul completion time is greater than a second time threshold, the first operation parameter can be determined to be a hidden danger parameter.
As shown in fig. 5, in an embodiment of the present invention, the troubleshooting path includes a plurality of line segment numbers, and fig. 5 shows a specific implementation flow of S103 in fig. 1, including:
s501: sequentially acquiring line information sent by sensors of all line sections according to the sequence of line section numbers in the troubleshooting path;
s502: and searching the fault line section according to the line information of each line section and the conventional information of the preset line.
In this embodiment, each line segment of the OTN network is provided with a sensor, the sensor may include a line data acquisition sensor and an infrared image sensor, and the line information includes line data and line images. The line data acquisition sensor is used for acquiring line data of the corresponding line section, the infrared image sensor acquires line images of the corresponding line section, and the line images can identify hidden dangers such as line damage, so that the occurrence of OTN network faults can be predicted, the potential safety hazards can be timely solved, and the safe and stable operation of the OTN network is guaranteed.
Specifically, the method for sequentially acquiring the line data of each line segment sensor in S501 may include two methods:
the first method comprises the following steps: the method comprises the steps that terminal equipment sends data acquisition instructions to all sensors on a line section in a troubleshooting path respectively, after each sensor acquires the data acquisition instructions, line data are acquired for the corresponding line section, the acquired line data are sent to the terminal equipment respectively, the terminal equipment sequentially acquires the line data sent by all the sensors according to line data acquisition time, and therefore troubleshooting is conducted on all the line sections.
And the second method comprises the following steps: according to the sequence of the line sections of the troubleshooting path, the terminal equipment firstly sends a data acquisition command to a sensor arranged on a first line section, acquires line data sent by a sensor of a first line section, sends the data acquisition command to a sensor of a second line section after determining that the first line section is free of faults, and repeats the steps until the line section with the faults is found, and stops downward troubleshooting. Because the probability that two line sections fail at the same time to cause failure in one line range is extremely low, after a failed line section is found, the failure can be determined as the reason that the first operating parameter exceeds the first parameter range, so that the data processing time of the terminal equipment is saved, and the troubleshooting result can be quickly given.
In this embodiment, the preset route general information includes a general route data range, and the specific flow of S502 includes:
1) judging whether the line data of each line section exceeds the range of the conventional line data;
2) if the line data exceeds the conventional line data range, taking the line section corresponding to the line data exceeding the conventional line data range as a fault line section;
3) if the line data does not exceed the conventional line data range, acquiring a line image acquired by an infrared image sensor of the line section, identifying and determining whether the line section is damaged or not through a neural network, and if the line section is damaged, determining that the line section is a fault line section.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
