The second preset time threshold is preset by the system, and the initial value is 5s.
According to an embodiment of the present invention, the adjusting the operation state of the optical module by closing the abnormal channel or adjusting the controllable parameter to make the faulty optical module perform the low operation state includes:
acquiring optical module channel information;

if not, the controllable parameters of the fault optical module are adjusted through a preset optical module operation data simulation model, so that the fault optical module enters a low operation state.
It should be noted that by reading the model parameters of the optical module, it can be determined whether the optical module is a single-channel optical module or a multi-channel optical module, for example, 100GBASE-LR4, where LR represents long reach, i.e., 10Km, and 4 represents four channels, i.e., 4G 25G, which are combined together to form a 100G optical module capable of transmitting 10 Km. If the optical module is a multi-channel optical module, each channel is detected through the system, in the detection process, the terminal closes all channels except the detection channel, records the detection data under the condition of single-channel transmission, repeatedly performs detection for a plurality of times to obtain the detection data of each channel, then analyzes based on the detection data of each channel, judges whether the single channel is abnormal in the data transmission process, positions the abnormal channel with the abnormality, closes the channel, and performs data transmission through other normal channels. In addition, under the condition that all channels of the multichannel optical module are abnormal or the single-channel optical module is abnormal, the detection data of the abnormal optical module can be imported into a preset optical module operation data simulation model, the operation state of the abnormal optical module is simulated through the model, and under the condition that a certain transmission speed is ensured, the abnormal parameters are restored to normal values by adjusting the controllable parameters, so that the transmission speed of the optical fiber is kept as far as possible under the condition that the optical module is not damaged.
The preset optical module operation data simulation model is obtained through training of historical detection data, and through the model, simulation analysis can be carried out on the operation state of the optical module, for example, when the numerical value of an abnormal parameter is required to be restored to a normal state, feasibility of a scheme is calculated, and an optimal scheme is selected for display. In addition, the time that the normal optical module is likely to have faults can be predicted by presetting the optical module operation data simulation model, so that early warning is carried out on the faults of the optical module in advance.
According to an embodiment of the present invention, further comprising:
acquiring abnormal channel closing time;
judging whether the closing time is larger than a third preset time threshold value or not;
when the closing time is greater than a third preset time threshold, analyzing the detection data of the fault light module to judge whether the fault light module is recovered to be normal or not;
if yes, the current state is maintained until the overhaul is completed; otherwise, the fault light module is controlled to enter a low running state.
It should be noted that, after the abnormal channel is closed, some parameter data will not change immediately, but a certain time is required to change, such as the temperature of the optical module. When the abnormal channel is closed and a third preset time threshold is reached, the system analyzes again according to the detection data uploaded by the DDM to judge whether the running data of the current fault optical module are all recovered to be normal, if so, the current state is maintained until the overhaul is completed; otherwise, acquiring simulation parameters through a preset optical module operation data simulation model, and controlling the fault optical module to enter a low operation state. The third preset time threshold is preset by the system, and the initial value is 20s.
Fig. 3 shows a flow chart of a method of the invention for bringing a faulty light module into a low operating state.
As shown in fig. 3, according to an embodiment of the present invention, the adjusting, by using a preset optical module operation data simulation model, a controllable parameter of the failed optical module, so that the failed optical module enters a low operation state includes:

s304, adjusting the controllable parameters of the fault light module according to the first simulation parameters, and adjusting the abnormal data of the fault light module to a corresponding preset threshold interval;
s306, analyzing the adjusted detection data of the fault light module, and judging whether the abnormal data of the fault light module is in a corresponding preset threshold interval or not after a fourth preset time threshold;
s308, if yes, the fault light module continues to transmit data based on the simulation parameters until the overhaul is completed;
and S310, if not, a second simulation parameter is obtained by the data simulation model operated by the preset optical module, and the controllable parameter of the fault optical module is adjusted by the second simulation parameter until the abnormal data of the fault optical module is in a corresponding preset threshold interval.
When the simulation analysis is performed by a preset optical module operation data simulation model, the simulation is mainly divided into three simulation grades, and the primary simulation is more than 70% of the total transmission rate of the optical module; the second-level simulation is that the total transmission rate of the optical module is more than 50% and less than or equal to 70%; the three-stage simulation is greater than 30% and less than or equal to 50% of the total transmission rate of the optical module. Firstly, simulating based on detection data of a current fault optical module through a model, determining a ratio of the highest transmission rate to the total transmission rate under the condition of converting abnormal data into normal data, thereby determining a simulation grade, and setting the simulation transmission rate as the minimum value of the current grade, thereby calculating to obtain parameter simulation parameters. For example, the calculated highest transmission rate is 68% of the total transmission rate, and is in the second-stage simulation level, and then 50% of the total transmission rate of the optical module is used as the simulation transmission rate to calculate, so as to obtain the first simulation parameter. And then, based on the first simulation parameters, adjusting controllable parameters (such as received light power, emitted light power, bias current and the like) of the current fault light module, recording adjustment time, and analyzing detection data of the current fault light module when the adjustment time reaches a fourth preset time threshold value to judge whether all the current fault light modules are in a normal state. If yes, maintaining the current parameters until the overhaul is completed; if not, continuing to simulate the transmission rate of the next level through the model to obtain a second simulation parameter, then adjusting the controllable parameters of the current fault optical module again based on the second simulation parameter, judging whether the detection data of the fault optical module are all in a normal state, and repeating the steps until the detection data of the fault optical module are all in the normal state. The first simulation parameter is a simulation operation parameter of the current level, the second simulation parameter is a simulation operation parameter of the next level, and the fourth preset time threshold is 20s.

if not, the controllable parameters of the fault optical module are adjusted through a preset optical module operation data simulation model, so that the fault optical module enters a low operation state.
It should be noted that by reading the model parameters of the optical module, it can be determined whether the optical module is a single-channel optical module or a multi-channel optical module, for example, 100GBASE-LR4, where LR represents long reach, i.e., 10Km, and 4 represents four channels, i.e., 4G 25G, which are combined together to form a 100G optical module capable of transmitting 10 Km. If the optical module is a multi-channel optical module, each channel is detected through the system, in the detection process, the terminal closes all channels except the detection channel, records the detection data under the condition of single-channel transmission, repeatedly performs detection for a plurality of times to obtain the detection data of each channel, then analyzes based on the detection data of each channel, judges whether the single channel is abnormal in the data transmission process, positions the abnormal channel with the abnormality, closes the channel, and performs data transmission through other normal channels. In addition, under the condition that all channels of the multichannel optical module are abnormal or the single-channel optical module is abnormal, the detection data of the abnormal optical module can be imported into a preset optical module operation data simulation model, the operation state of the abnormal optical module is simulated through the model, and under the condition that a certain transmission speed is ensured, the abnormal parameters are restored to normal values by adjusting the controllable parameters, so that the transmission speed of the optical fiber is kept as far as possible under the condition that the optical module is not damaged.
The preset optical module operation data simulation model is obtained through training of historical detection data, and through the model, simulation analysis can be carried out on the operation state of the optical module, for example, when the numerical value of an abnormal parameter is required to be restored to a normal state, feasibility of a scheme is calculated, and an optimal scheme is selected for display. In addition, the time that the normal optical module is likely to have faults can be predicted by presetting the optical module operation data simulation model, so that early warning is carried out on the faults of the optical module in advance.
According to an embodiment of the present invention, further comprising:
acquiring abnormal channel closing time;
judging whether the closing time is larger than a third preset time threshold value or not;
when the closing time is greater than a third preset time threshold, analyzing the detection data of the fault light module to judge whether the fault light module is recovered to be normal or not;
if yes, the current state is maintained until the overhaul is completed; otherwise, the fault light module is controlled to enter a low running state.
It should be noted that, after the abnormal channel is closed, some parameter data will not change immediately, but a certain time is required to change, such as the temperature of the optical module. When the abnormal channel is closed and a third preset time threshold is reached, the system analyzes again according to the detection data uploaded by the DDM to judge whether the running data of the current fault optical module are all recovered to be normal, if so, the current state is maintained until the overhaul is completed; otherwise, acquiring simulation parameters through a preset optical module operation data simulation model, and controlling the fault optical module to enter a low operation state. The third preset time threshold is preset by the system, and the initial value is 20s.
According to an embodiment of the present invention, the adjusting the controllable parameters of the failed optical module through the preset optical module operation data simulation model to enable the failed optical module to enter a low operation state includes:
inputting detection data of the fault optical module into the preset optical module operation data simulation model for simulation analysis, and adjusting the abnormal value to a corresponding preset threshold interval by adjusting the controllable parameter to obtain a first simulation parameter;

analyzing the adjusted detection data of the fault light module, and judging whether the abnormal data of the fault light module is in a corresponding preset threshold interval or not after a fourth preset time threshold;
if yes, the fault light module continues to transmit data based on the simulation parameters until the overhaul is completed;
if not, a second simulation parameter is obtained through the data simulation model of the preset optical module, and the controllable parameter of the fault optical module is adjusted through the second simulation parameter until the abnormal data of the fault optical module is in a corresponding preset threshold interval.
When the simulation analysis is performed by a preset optical module operation data simulation model, the simulation is mainly divided into three simulation grades, and the primary simulation is more than 70% of the total transmission rate of the optical module; the second-level simulation is that the total transmission rate of the optical module is more than 50% and less than or equal to 70%; the three-stage simulation is greater than 30% and less than or equal to 50% of the total transmission rate of the optical module. Firstly, simulating based on detection data of a current fault optical module through a model, determining a ratio of the highest transmission rate to the total transmission rate under the condition of converting abnormal data into normal data, thereby determining a simulation grade, and setting the simulation transmission rate as the minimum value of the current grade, thereby calculating to obtain parameter simulation parameters. For example, the calculated highest transmission rate is 68% of the total transmission rate, and is in the second-stage simulation level, and then 50% of the total transmission rate of the optical module is used as the simulation transmission rate to calculate, so as to obtain the first simulation parameter. And then, based on the first simulation parameters, adjusting controllable parameters (such as received light power, emitted light power, bias current and the like) of the current fault light module, recording adjustment time, and analyzing detection data of the current fault light module when the adjustment time reaches a fourth preset time threshold value to judge whether all the current fault light modules are in a normal state. If yes, maintaining the current parameters until the overhaul is completed; if not, continuing to simulate the transmission rate of the next level through the model to obtain a second simulation parameter, then adjusting the controllable parameters of the current fault optical module again based on the second simulation parameter, judging whether the detection data of the fault optical module are all in a normal state, and repeating the steps until the detection data of the fault optical module are all in the normal state. The first simulation parameter is a simulation operation parameter of the current level, the second simulation parameter is a simulation operation parameter of the next level, and the fourth preset time threshold is 20s.
