Example 1
According to an embodiment of the present application, there is provided an embodiment of a method of determining a communication link, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order other than that shown or described herein.
It should be further noted that, an intelligent operation and maintenance system may be used as an execution body of the method for determining a communication link in the embodiment of the present application. The intelligent operation and maintenance system at least comprises an optical cable monitoring subsystem and an optical switching protection subsystem.
Fig. 1 is a flow chart of an alternative method of determining a communication link according to an embodiment of the present application, as shown in fig. 1, the method comprising the steps of:
step S101, acquiring first state information of a first communication link and second state information of a second communication link.
In step S101, the first state information indicates whether the first communication link is in an abnormal state, and the second state information indicates whether the second communication link is in an abnormal state, and the second communication link is a backup link of the first communication link.
The first communication link and the second communication link may be optical cables in the power optical cable system, or may be other links that may be used to transmit communication data, such as telephone lines and network cables. The application is mainly described by taking a first communication link as a first optical cable and a second communication link as a second optical cable.
It should be noted that, the optical cable monitoring subsystem may send test signals to the first optical cable and the second optical cable, respectively, and then determine the state information of the corresponding optical cable according to the attenuation information and the reflection information when the test signals are transmitted in the first optical cable and the second optical cable. The state information of each optical cable at least comprises the length of the optical cable, the whole-process loss of the optical cable, the section loss of the optical cable, the optical cable length historical data, the optical cable whole-process loss historical data and the fault point of the optical cable. Such status information may characterize whether the fiber optic cable is in an abnormal state, e.g., when the length of the fiber optic cable does not match the fiber optic cable length history data, indicating that the fiber optic cable is in an abnormal state; when the whole-process loss of the optical cable is larger than the preset whole-process maximum loss, the optical cable is in an abnormal state; and under the condition that the section loss of the optical cable is larger than the preset section maximum loss, the optical cable is in an abnormal state.
Specifically, the length of the optical cable is the specific length of the optical cable; the whole-course loss of the optical cable is the loss value from the starting point to the end point of the optical cable, and the dB is taken as a unit, and meanwhile, the optical cable monitoring subsystem can automatically calculate the whole-course average loss of the optical cable; the section loss of the optical cable is the loss of the section between any two large reflection points of the optical cable, and the large reflection points mainly refer to movable joints, connection points with poor welding quality and the like on the optical cable; the optical cable length historical data are information such as a length value, test time, optical cable identification and the like of the optical cable monitored by the optical cable detection subsystem in a specified historical time period; the optical cable whole-process loss historical data are information such as whole-process loss values, test time, optical cable identifications and the like of the optical cable monitored by the optical cable monitoring subsystem in a specified historical time period; the fault point is a position where a fault exists on the optical cable when the optical cable is in an abnormal state.
According to the analysis, the operation state of each communication link can be accurately obtained in real time by obtaining the first state information and the second state information, so that when any communication link is abnormal, abnormal information can be obtained at the first time, and further the operation and maintenance efficiency of the abnormal link is improved.
Step S102, a target communication link is determined according to the first state information and the second state information.
In step S102, the target communication link is a communication link for transmitting communication data, and the target communication link is a first communication link in a normal state or a second communication link in a normal state.
The optical switching protection subsystem is connected with the optical cable monitoring subsystem, and the optical cable monitoring subsystem can send the first state information and the second state information to the optical switching protection subsystem after obtaining the first state information and the second state information. On the basis, the optical switching protection subsystem determines whether the first communication link and the second communication link are in an abnormal state according to the first state information and the second state information. Because the first communication link is a main communication link and the second communication link is a standby link of the first communication link, when the first communication link is in a normal state and the second communication link is also in a normal state, the first communication link is preferentially selected as a target communication link; when the first communication link is in an abnormal state and the second communication link is in a normal state, selecting the second communication link as a target communication link, generating alarm information aiming at the abnormal state of the first communication link, and re-determining the first communication link as the target communication link after detecting that the first communication link is recovered to be normal; and under the condition that the first communication link is in a normal state and the second communication link is in an abnormal state, determining the first communication link as a target communication link, and generating alarm information aiming at the abnormal state of the second communication link. In practical application, more standby communication links may be set, for example, a third communication link, where the third communication link is used as a standby link of the first communication link and the second communication link, and when the first communication link and the second communication link are abnormal at the same time, the third communication link is determined to be a target communication link.
By determining the target communication link according to the state information of each communication link, stable transmission of communication data is ensured, so that the communication data cannot be interrupted due to the fault of one communication link, and the fault tolerance rate and the safety of data transmission are improved.
As can be seen from the foregoing contents of steps S101 to S102, in the embodiment of the present application, the standby link is configured for the first communication link, and the state information of the first communication link and the standby link of the first communication link are simultaneously acquired, and after the first state information of the first communication link and the second state information of the second communication link are acquired, the target communication link is determined according to the first state information and the second state information. The first state information represents whether the first communication link is in an abnormal state or not, the second state information represents whether the second communication link is in an abnormal state or not, the second communication link is a standby link of the first communication link, the target communication link is a communication link for transmitting communication data, and the target communication link is the first communication link in a normal state or the second communication link in a normal state.
From the foregoing, it can be seen that the present application can provide more transmission paths for communication data by configuring the second communication link as a backup link for the first communication link. And secondly, the application can acquire the first state information of the first communication link and the second state information of the second communication link at the same time, thereby realizing the effect of accurately acquiring the running state of each communication link in real time. In addition, the application can also determine the link in the normal state from the first communication link and the second communication link as the target communication link according to the first state information and the second state information, thereby ensuring that the communication data is not interrupted to be transmitted because of the abnormality of one communication link, ensuring the stable operation of the communication service of the user, and simultaneously competing for the maintenance time for the maintenance of the abnormal communication link by the operation and maintenance personnel, and further improving the operation and maintenance efficiency and the user experience.
Therefore, the technical scheme of the application achieves the purpose of automatically detecting the running state of the communication link, achieves the effect of improving the transmission stability of communication data, and solves the technical problem of low operation and maintenance efficiency of the communication link caused by the fact that the state of the communication link cannot be automatically detected in the prior art.
In an alternative embodiment, the cable monitoring subsystem determines the first status information by obtaining attenuation information and reflection information of the first optical signal and then determining the first status information based on the attenuation information and reflection information of the first optical signal. Wherein the first optical signal is a test signal transmitted in the first communication link. Similarly, the optical cable monitoring subsystem obtains attenuation information and reflection information of the second optical signal, and then determines second state information according to the attenuation information and the reflection information of the second optical signal. Wherein the second optical signal is a test signal transmitted in the second communication link.
Alternatively, FIG. 2 is a schematic diagram of an alternative fiber optic cable monitoring process according to an embodiment of the present application. As shown in fig. 2, the cable monitoring subsystem may implement state detection and fault location of the cable based on the COTDR technology principle of parallel correlation codec, according to attenuation and reflection of the modulated signal in the single mode fiber. When the optical fiber testing device is particularly applied, a testing signal is sent to an optical fiber in an optical cable through a testing signal generator, and then attenuation information and reflection information of the testing signal are obtained through a signal detector. For example, a photoelectric detector with proper optical coupling and high-speed response is selected as a signal detector, the attenuation information and reflection information of a test signal can be determined by detecting the size and arrival time of back light, and then the state information such as the transmission characteristic, the length and the fault point of the optical fiber can be quantitatively measured by calculating the parallel correlation algorithm arranged in the FPGA (Field Programmable GATE ARRAY ) chip on the basis of the attenuation information and the reflection information.
It should be noted that fig. 3 shows a schematic diagram for determining the state of the optical cable according to the test signal, and as shown in fig. 3, after the analysis transformation of the parallel correlation algorithm, the attenuation information and the reflection information of the test signal may be presented in the form of curves. It is easy to understand that the test signal is an optical signal, and when the transmission line is bent or broken, the attenuation information and reflection information of the test signal will change to different degrees, and the change will be reflected on the fluctuation of the curve. Thus, in FIG. 3, the position of the connector in the cable, the position where the bend exists, the position of the cross section, and the test signal noise can be clearly determined based on the wavy characteristics of the curve.
In an alternative embodiment, when the first communication link is abnormal, the optical cable monitoring subsystem determines a position of a fault on the first communication link according to attenuation information and reflection information of the first optical signal, so as to obtain a first fault point, determines a first fault position corresponding to the first fault point in a map, and sends the first fault position to the target terminal device; when the second communication link is abnormal, the optical cable monitoring subsystem determines the position of the fault on the second communication link according to the attenuation information and the reflection information of the second optical signal to obtain a second fault point, determines the second fault position corresponding to the second fault point in the map, and sends the second fault position to the target terminal equipment.
In the prior art, optical cable resources and GIS (geographic information system ) resources are not effectively combined, when an optical cable fails, operation and maintenance personnel judge the position of a failure point according to experience, and the failure detection time is long and the problem of failure repair process is affected in the mode. In order to solve the problem, the application combines the fault point monitored by the optical cable monitoring subsystem with the GIS resource, and can directly embody the position of the fault point on the map, thereby improving the operation and maintenance efficiency of operation and maintenance personnel. As shown in fig. 4, fig. 4 shows a GIS display effect diagram of an optical cable line resource, in which the location of a fault point may be clearly displayed in a map.

Specifically, the at least two communication links may be the first communication link and the second communication link in embodiment 1, which may be optical cables in the power optical cable system, or may be other links that may be used to transmit communication data, such as telephone lines, network lines, and the like. The application is mainly described by taking a first communication link as a first optical cable and a second communication link as a second optical cable.
The link state detection unit may be an optical cable monitoring subsystem in embodiment 1, configured to obtain first state information of a first communication link and second state information of a second communication link, where the first state information indicates whether the first communication link is in an abnormal state, the second state information indicates whether the second communication link is in an abnormal state, and the second communication link is a backup link of the first communication link.
It should be noted that, the optical cable monitoring subsystem may send test signals to the first optical cable and the second optical cable, respectively, and then determine the state information of the corresponding optical cable according to the attenuation information and the reflection information when the test signals are transmitted in the first optical cable and the second optical cable. The state information of each optical cable at least comprises the length of the optical cable, the whole-process loss of the optical cable, the section loss of the optical cable, the optical cable length historical data, the optical cable whole-process loss historical data and the fault point of the optical cable. Such status information may characterize whether the fiber optic cable is in an abnormal state, e.g., when the length of the fiber optic cable does not match the fiber optic cable length history, indicating that the fiber optic cable is in an abnormal state; under the condition that the whole-process loss of the optical cable is larger than the preset whole-process maximum loss, the optical cable is in an abnormal state; and under the condition that the section loss of the optical cable is larger than the preset section maximum loss, the optical cable is in an abnormal state.
Specifically, the length of the optical cable is the specific length of the optical cable; the whole-course loss of the optical cable is the loss value from the starting point to the end point of the optical cable, and the dB is taken as a unit, and meanwhile, the optical cable monitoring subsystem can automatically calculate the whole-course average loss of the optical cable; the section loss of the optical cable is the loss of the section between any two large reflection points of the optical cable, and the large reflection points mainly refer to movable joints, connection points with poor welding quality and the like on the optical cable; the optical cable length historical data are information such as a length value, test time, optical cable identification and the like of the optical cable monitored by the optical cable detection subsystem in a specified historical time period; the optical cable whole-process loss historical data are information such as whole-process loss values, test time, optical cable identifications and the like of the optical cable monitored by the optical cable monitoring subsystem in a specified historical time period; the fault point is a position where a fault exists on the optical cable when the optical cable is in an abnormal state.

By determining the target communication link according to the state information of each communication link, stable transmission of communication data is ensured, so that the communication data cannot be interrupted due to the fault of one communication link, and the fault tolerance rate and the safety of data transmission are improved.
According to the method and the device, the effect of accurately acquiring the running state of each communication link in real time is achieved, and on the basis, if any communication link is abnormal, the method and the device can acquire abnormal information at the first time, so that the efficiency of determining the abnormal communication link by operation and maintenance personnel can be improved. In addition, the application can also determine the link in the normal state from a plurality of communication links as a target communication link according to the state information of each communication link, thereby ensuring that communication data is not interrupted to be transmitted because of the abnormality of one communication link, ensuring the stable operation of communication service of a user, and simultaneously competing for maintenance time for maintenance of the abnormal communication link by operation and maintenance personnel, and further improving operation and maintenance efficiency and user experience.
