Example 1
In accordance with an embodiment of the present application, there is provided an embodiment of a method for determining a communication link, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
It should be further noted that an intelligent operation and maintenance system may be used as an execution subject of the determination method of the 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 flowchart of an alternative communication link determination method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S101, obtain first status information of the first communication link and second status information of the second communication link.
In step S101, the first state information represents whether the first communication link is in an abnormal state, and the second state information represents whether the second communication link is in an abnormal state, where the second communication link is a standby link of the first communication link.
The first communication link and the second communication link may be optical cables in an electrical power optical cable system, or may be other links that can be used to transmit communication data, such as telephone lines and network lines. The present application mainly uses 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 of the test signals during the transmission process 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, historical data of the length of the optical cable, historical data of the whole-process loss of the optical cable and a fault point of the optical cable. The status information may indicate whether the optical cable is in an abnormal state, for example, when the length of the optical cable does not match the historical data of the length of the optical cable, the optical 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 when the section loss of the optical cable is greater 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-process loss of the optical cable is the loss value of the optical cable from the starting point to the end point, the unit is dB, and meanwhile, the whole-process average loss of the optical cable can be automatically calculated by the optical cable monitoring subsystem; the section loss of the optical cable is the section loss between any two large reflection points of the optical cable, and the large reflection points mainly refer to movable joints on the optical cable, splicing points with poor welding quality and the like; the historical data of the optical cable length is information such as the length value, the test time, the optical cable identification and the like of the optical cable which is monitored by the optical cable detection subsystem in a specified historical time period; the historical data of the whole-course loss of the optical cable is information such as a whole-course loss numerical value, test time, an optical cable identification 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 running 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 one communication link is abnormal, abnormal information can be obtained at the first time, and the operation and maintenance efficiency of the abnormal link is improved.
And step S102, determining a target communication link 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, the first communication link is preferentially selected as a target communication link when the first communication link is in a normal state and the second communication link is also in a normal state; under the condition that 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 that the first communication link is a target communication link, and generating alarm information aiming at the abnormal state of the second communication link. It should be noted that, in practical applications, more backup communication links may be set, for example, a third communication link is used as a backup link for 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 as the target communication link.
The target communication link is determined according to the state information of each communication link, so that stable transmission of communication data is ensured, the transmission of 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 above contents of step S101 to step S102, in the embodiment of the present application, a manner of configuring a backup link for a first communication link and simultaneously acquiring state information of the first communication link and the backup link of the first communication link is adopted, and after acquiring first state information of the first communication link and second state information of a second communication link, a 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, the second state information represents whether the second communication link is in an abnormal state, 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.
As can be seen from the above, the present application can provide more transmission paths for communication data by configuring the second communication link as the backup link for the first communication link. Secondly, the first state information of the first communication link and the second state information of the second communication link are obtained at the same time, so that the effect of accurately obtaining the running state of each communication link in real time is achieved. In addition, according to the first state information and the second state information, the link in the normal state can be determined from the first communication link and the second communication link to serve as the target communication link, so that the communication data can not be transmitted due to the fact that one communication link is abnormal, maintenance time can be won for maintenance of the abnormal communication link by operation and maintenance personnel while the stable operation of the communication service of the user is guaranteed, and operation and maintenance efficiency and user experience are further improved.
Therefore, by the technical scheme, the purpose of automatically detecting the running state of the communication link is achieved, the effect of improving the transmission stability of the communication data is achieved, and the technical problem that the operation and maintenance efficiency of the communication link is low due to the fact that the state of the communication link cannot be automatically detected in the prior art is solved.
In an alternative embodiment, the cable monitoring subsystem determines the first status information by obtaining attenuation information and reflection information for the first optical signal and then determining the first status information based on the attenuation information and reflection information for 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 determines the second state information according to the attenuation information and the reflection information of the second optical signal by acquiring 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 cable monitoring process according to an embodiment of the present application. As shown in fig. 2, the optical cable monitoring subsystem may implement the status detection and fault location of the optical cable according to the attenuation and reflection of the modulated signal in the single-mode optical fiber by the COTDR technology principle based on parallel correlation encoding and decoding. When the optical cable is applied specifically, a test signal is sent to an optical fiber in the optical cable through a test signal generator, and then attenuation information and reflection information of the test signal are obtained through a signal detector. For example, a photodetector with appropriate optical coupling and high-speed response is selected as a signal detector, attenuation information and reflection information of a test signal can be determined by detecting the size and arrival time of back light, and then state information such as transmission characteristics, length, and failure point of an optical fiber can be quantitatively measured by calculation through a parallel correlation algorithm provided in an 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 of determining the state of the optical cable according to the test signal, and as shown in fig. 3, after the analysis transformation by the parallel correlation algorithm, the attenuation information and the reflection information of the test signal can be presented in the form of a curve. It is easily understood that the test signal is an optical signal, and when the transmission line is bent or broken, the attenuation information and the reflection information of the test signal will be changed to different degrees, and the change is reflected on the fluctuation of the curve. Therefore, in fig. 3, from the fluctuation characteristics of the curve, the position of the connector in the optical cable, the position where the bend exists, the position of the cross section, and the test signal noise can be clearly judged.
In an optional embodiment, when the first communication link is abnormal, the optical cable monitoring subsystem determines a position where a fault exists on the first communication link according to attenuation information and reflection information of the first optical signal 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; and when the second communication link is abnormal, the optical cable monitoring subsystem determines the position of the second communication link with the fault according to the attenuation information and the reflection information of the second optical signal to obtain a second fault point, determines a 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, and when an optical cable fails, operation and maintenance personnel usually judge the position of the failure point according to experience, which may cause a long troubleshooting time and affect the failure repair process. In order to solve the problem, the fault point monitored by the optical cable monitoring subsystem is combined with the GIS resource, and the position of the fault point can be directly reflected on a map, so that the operation and maintenance efficiency of operation and maintenance personnel is improved. As shown in fig. 4, fig. 4 shows a GIS display effect diagram of the optical cable line resource, wherein the location of the fault point can be clearly displayed in the 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 an electrical power optical cable system, or other links that can be used to transmit communication data, such as telephone lines and network lines. The present application mainly uses 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 the optical cable monitoring subsystem in embodiment 1, and is configured to acquire first state information of the first communication link and second state information of the second communication link, where 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 standby link of the first communication link.

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, historical data of the length of the optical cable, historical data of the whole-process loss of the optical cable and a fault point of the optical cable. The status information may indicate whether the optical cable is in an abnormal status, for example, when the length of the optical cable does not match the historical data of the length of the optical cable, the optical cable is in an abnormal status; 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 when 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 of the optical cable from the starting point to the end point, the unit is dB, and meanwhile, the whole-course average loss of the optical cable can be automatically calculated by the optical cable monitoring subsystem; the section loss of the optical cable is the section loss between any two large reflection points of the optical cable, and the large reflection points mainly refer to movable joints on the optical cable, splicing points with poor welding quality and the like; the historical data of the optical cable length is information such as the length value, the test time, the optical cable identification and the like of the optical cable monitored by the optical cable detection subsystem in a specified historical time period; the historical data of the whole-course loss of the optical cable is information such as a whole-course loss numerical value, test time, an optical cable identification 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.
