Fig. 2 is a flowchart of a method for monitoring interference according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
step S202, monitoring that the phase value of the optical signal transmitted on the target monitoring optical fiber changes;
step S204, determining a first characteristic parameter of a vibration frequency signal of an optical cable where the target monitoring optical fiber is located based on the phase value;
step S206, matching the first characteristic parameter with a characteristic parameter stored in a preset sample library to determine the type of the behavior signal of the optical cable subjected to the interference, where the behavior signal and the corresponding characteristic parameter are stored in the preset sample library.
Alternatively, the main body of execution of the above steps may be the computer terminal and the like in embodiment 1, but is not limited thereto.
Through the steps, when the phase value of the optical signal transmitted on the target monitoring optical fiber is monitored to be changed, the characteristic parameter of the vibration frequency signal of the monitored optical cable is matched with the characteristic parameter stored in the preset sample library to determine the interference type of the optical cable subjected to interference, so that the problem that the interference type of the optical cable subjected to interference cannot be accurately identified in the related technology can be solved, the maintenance personnel can efficiently identify the fault optical cable, and the maintenance efficiency of an optical cable line is improved.
In an alternative embodiment, matching the first characteristic parameter with a characteristic parameter stored in a preset sample library to determine the type of the optical cable disturbed comprises: searching a target characteristic parameter comprising a first characteristic parameter in a preset sample library; and determining the type of the behavior signal corresponding to the target characteristic parameter as the type of the optical cable subjected to interference. In this embodiment, the first characteristic parameter may include a frequency, an amplitude, a spatial scale, and other parameter values of the vibration frequency signal; in addition, when the target monitoring optical cable is not interfered, a large number of behavior signals (such as knocking, digging, smashing and the like) are collected through the system, and characteristic parameters of all the behavior signals are calculated through functions and stored to form a preset sample library. Because the characteristic parameters generated by the interference of each behavior signal on the optical cable are different, the characteristic parameters of the vibration frequency signal of the current target monitoring optical cable are matched with the characteristic parameters stored in the preset sample library, the interference type of the interference on the target monitoring optical cable can be identified, and the problem that the workload of emergency maintenance personnel is increased because monitoring equipment in the related technology can only monitor the optical cable to have a fault and cannot accurately identify the fault type is solved.
In an optional embodiment, after monitoring that the phase value of the optical signal transmitted on the target monitoring fiber changes, the method further includes: determining a time difference between a transmitted optical signal and a received scattered signal with a changed phase, wherein the scattered signal is a signal scattered back when the optical signal is transmitted in a target monitoring optical fiber; and determining the position information of the target monitoring optical cable subjected to interference based on the time difference and the speed of light. In this embodiment, because the optical signal returns to the scattering signal when transmitted through the optical fiber, the phase value of the optical signal under normal conditions is not changed, and if the position of the a point on the target optical cable is interfered, the optical path waveform of the optical signal changes, and the phase value of the optical path waveform also changes, therefore, by monitoring the time for sending the optical pulse signal to the optical fiber and the time for receiving the scattering signal with the changed phase value, based on the time difference between the two and the optical propagation speed, the length of the optical fiber between the interfered position of the a point on the optical cable and the monitoring device can be calculated, and further the position information of the interfered position of the a point on the optical cable is determined, so that accurate interference positioning can be achieved, and the problem that an optical cable identifier in the related art can only identify a faulty optical cable, but cannot position a fault is solved.
In an optional embodiment, after determining the location information, the method further includes: and generating first alarm information, wherein the first alarm information carries position information. In this embodiment, after the length of the optical fiber interfered by the target monitoring optical fiber is determined, the system determines the position information of the interference through the length of the optical fiber, and then alarms (i.e., first alarm information) occur, so as to monitor in real time the early warning of the position information which may cause damage to the optical cable. Optionally, after the length of the optical fiber is obtained, by comparing the longitude and latitude information of the positioning of the point a, when an alarm is given, the system can determine the longitude and latitude information of the alarm point according to the length of the optical fiber, so that the problem that the OTDR in the related art can only monitor the attenuation information along the optical fiber, and the problem that the conventional OTDR technology can only measure the actual length of the fault optical cable during fault positioning and cannot conform to the specific position of the geographic information can be solved.
In an optional embodiment, the method further includes: and generating second alarm information, wherein the second alarm information carries information of the type of the behavior signal of the optical cable subjected to the interference. In this embodiment, after the interference type of the target monitoring optical cable subjected to interference is determined, the system may also send out alarm information (i.e., second alarm information), so as to monitor in real time the early warning of the behavior signal that may cause damage to the optical cable. Optionally, the first alarm information and the second alarm information may be the same information, that is, the alarm information generated by the system carries the type of the behavior signal of the optical cable that is interfered and the interfered position location information.
