[0059] S500: based on the resource utilization flexibility, obtaining the redundant resources wasted in the emergency scheme, and performing resource disposal according to the redundant resources.

[0060] It should be pointed out that the above steps are only preferred implementation sequence, and in the specific implementation process, part of the steps can be exchanged without affecting the overall implementation effect.

[0061] The step of obtaining the fault data of the power communication network and performing data analysis on the fault data to obtain the fault reason is specifically:

[0062] Obtaining fault data of the power communication network, extracting fault attributes of the power communication network according to the fault data, and performing weighted processing on the fault attributes to obtain weighted fault attributes;

[0063] The fault data is sorted and classified to obtain a plurality of fault data sets, and an association relationship is established between the plurality of fault data sets to generate a data set network;

[0064] The data set network is weighted and parallel data mining is performed to obtain the fault range, fault demand and fault phenomenon of the power communication network;

[0065] Based on the weighted fault attributes and the fault demand, the fault range is detected in two parts to determine the fault location, and the fault cause is obtained in combination with the fault location and the fault phenomenon.

[0066] In an embodiment, the power communication network of a certain region is taken as an example, the fault data of the power communication network of the region is obtained through the power communication network system, the fault data is analyzed to obtain the fault attribute as network channel failure, and the weighted fault attribute of the network channel failure is obtained by weighting. The fault data is sorted and classified to obtain a plurality of fault data sets, each of which contains fault data of different regions and different weighted fault attributes, and an association relationship is established between the fault data sets to generate a data set network. Data mining is performed in the data set network, that is, multi-level data mining and data association are performed on each fault data set and the associated fault data set to obtain the fault range of the power communication network as a large mountainous area, the fault demand as restoring the communication function of the power communication network in the fault range, and the fault phenomenon as being unable to forward data through the power communication network in the region. According to the fault attribute and the fault demand, the fault range is further detected in two parts, and three fault locations are determined step by step. According to the fault location and the fault phenomenon, it is further determined that the fault cause is two data path terminals and one infrastructure damage.

[0067] Based on the fault cause, an emergency scheme corresponding to the fault cause is extracted, and the emergency scheme is simulated and implemented to obtain the application defect data of the emergency scheme, which comprises the following steps:

[0068] Based on the fault cause, an emergency scheme corresponding to the fault cause is extracted, and the emergency scheme is simulated and implemented to obtain the application defect data of the emergency scheme, which comprises the following steps:

[0069] Obtaining the construction data of the power communication network in the fault range, and generating a simulated fault environment according to the construction data;

[0070] Based on the simulated fault environment, the emergency scheme is simulated and implemented in the fault simulation environment to obtain simulation implementation data;

[0071] A data defect standard is established, and the simulation implementation data is screened according to the data defect standard to obtain application defect data.

[0072] In an application, for example, a power communication network in a certain region has three faults. According to the obtained fault reasons, an emergency scheme corresponding to the fault reasons is searched in an emergency scheme library, construction data of the power communication network in the region is obtained, and a simulation fault environment is generated according to the construction data. In the simulation fault environment, the searched emergency scheme is simulated and implemented, and simulation implementation data is obtained according to the implementation of the simulation implementation. A data defect standard is established, and the simulation implementation data is compared with the data defect standard. According to the comparison result, application defect data in the simulation implementation process is obtained by screening.

[0073] The application defect data is subjected to security analysis to obtain the application security risk of the emergency scheme, and the steps are as follows:

[0074] Based on the application defect data, route planning information, channel robustness data, data loss information, and data flow information are extracted from the application defect data.

[0075] According to the route planning information and the channel robustness data, route channel risks in the emergency scheme are obtained.

[0076] According to the data loss information and the data flow information, data security risks in the emergency scheme are obtained.

[0077] The route channel risks and the data security risks are combined to obtain the application security risk of the emergency scheme.

[0078] In an application, for example, a power communication network in a certain region has three faults. According to the obtained fault reasons, an emergency scheme corresponding to the fault reasons is searched in an emergency scheme library, construction data of the power communication network in the region is obtained, and a simulation fault environment is generated according to the construction data. In the simulation fault environment, the searched emergency scheme is simulated and implemented, and simulation implementation data is obtained according to the implementation of the simulation implementation. A data defect standard is established, and the simulation implementation data is compared with the data defect standard. According to the comparison result, application defect data in the simulation implementation process is obtained by screening.

[0079] The application defect data is subjected to utilization rate analysis to obtain the resource utilization flexibility of the emergency scheme, and the steps are as follows:

[0080] Based on the application defect data, the application defect data is data cleaned, and the cleaned application defect data is data screened to obtain a fault point of the power communication network and a coverage range of the emergency scheme to the fault point respectively;

[0081] According to the fault point and the coverage range, the number of available resources of the power communication network in the coverage range is obtained, and the used information of the number of available resources is extracted;

[0082] The number of available resources is compared with the number of emergency resources provided by the emergency scheme to obtain the resource waste amount of the emergency scheme;

[0083] According to the resource waste amount and the used information of the number of available resources, the resource utilization flexibility of the emergency scheme is obtained.

[0084] In the application, taking a power communication network in a certain region as an example, according to the application defect data, the application defect data is data cleaned and data screened to obtain three fault points of the power communication network, which are two path interruptions and one infrastructure damage, and the coverage range of the emergency scheme to the three fault points is 200% coverage. According to the fault point and the coverage range, the number of available resources of the power communication network in the coverage range is 50% of the total resource quantity, and the used information of the number of available resources is obtained, including path information and infrastructure information. The number of available resources is compared with the number of emergency resources provided by the emergency scheme to obtain the wasted resource waste amount of 50% in the emergency scheme. The resource waste amount of 50% represents the amount of resources that can be compensated by the resources of the power communication network itself. According to the resource waste amount and the used information of the number of available resources, the resource utilization flexibility of the emergency scheme is 50%.

[0085] Based on the security risk, the risk focus of the security risk is obtained, and the steps of risk adjustment of the emergency scheme according to the risk focus are as follows:

[0086] Based on the security risk, the risk bias of the security risk is identified to obtain the risk focus of the security risk;

[0087] According to the risk focus, the risk type of the security risk is obtained, and the focus amount of the risk focus is extracted, and the risk level is obtained according to the focus amount;

[0088] It is judged whether the risk level exceeds the preset level threshold, if it is judged that the risk level exceeds the level threshold, the occurrence mode of the security risk is predicted according to the risk type;

[0089] According to the occurrence mode, the coping strategy of the security risk is generated, and the risk adjustment of the emergency scheme is carried out according to the coping strategy.

[0090] In use, taking the power communication network of a certain region as an example, according to the obtained security risk, the risk bias of the security risk is identified, and the risk bias of the security risk is obtained as path risk and data risk. According to the risk bias, the risk type of the security risk is further obtained as a data transmission risk type, the weight of the risk bias is extracted as 70%, the risk level is obtained as 7, and the preset level threshold is 5. Therefore, the risk level exceeds the level threshold, and the occurrence mode of the security risk is predicted according to the data transmission risk type, which may be human damage or damage caused by geology and weather, etc. According to the coping strategies of the security risk according to these occurrence modes, for example, adjusting the wired transmission mode to the wireless transmission mode, and using the bypass mode for data path, the risk adjustment is carried out on the emergency plan.

[0091] Based on the resource utilization flexibility, the wasted redundant resources in the emergency plan are obtained, and the steps of disposing the redundant resources according to the redundant resources are as follows:

[0092] The total amount of resources in the emergency plan is extracted, and the total amount of resources is screened according to the resource utilization flexibility, so as to obtain the wasted redundant resources in the emergency plan;

[0093] Based on the redundant resources, the resource allocation position of the redundant resources is identified, and the redundant position of the redundant resources is obtained;

[0094] Based on the redundant position, the resource position corresponding to the redundant position is searched on the power communication network;

[0095] According to the resource position, the reliability value of the communication resource at the resource position is obtained, and it is judged whether the reliability value is higher than the preset reliability threshold;

[0096] If it is judged that the reliability value is greater than or equal to the reliability threshold, the redundant resources are recycled, and if it is judged that the reliability value is less than the reliability threshold, the redundant resources are replaced by the communication resources.

[0097] In use, taking the power communication network of a certain region as an example, the total amount of resources in the emergency plan is extracted as 100, the wasted redundant resources in the emergency plan are obtained according to the resource utilization flexibility as 50, the allocation position of the redundant resources is identified according to the redundant resources, and the redundant position of the redundant resources is obtained as some paths or infrastructures that can work normally or are in a safe position. According to the corresponding resource position in the power communication network, the reliability value of the communication resource on the power communication network is obtained according to the resource position, and the reliability value is judged. It is found that the reliability values of two paths are not high, and the reliability value of one infrastructure is very high. Therefore, the redundant resources are replaced by the redundant resources of the two paths with different reliability values, and the redundant resources originally used to replace the infrastructure are recycled.

[0098] If it is judged that the reliability value is greater than or equal to the reliability threshold value, the redundant resource is recycled, and if it is judged that the reliability value is less than the reliability threshold value, the redundant resource is replaced by the communication resource.

[0099] The resource type of the redundant resource is acquired, and the resource type is matched on the power communication network to obtain a matched resource on the power communication network;

[0100] The redundant resource and the matched resource are compared in terms of overlap to obtain a coverage rate of the redundant resource to the matched resource;

[0101] If the coverage rate is greater than 100%, the redundant resource and the matched resource are compared in terms of reliability value;

[0102] If it is judged that the reliability value of the redundant resource is greater than the reliability value of the matched resource, the redundant resource is used to replace the matched resource;

[0103] If it is judged that the reliability value of the redundant resource is less than or equal to the reliability value of the matched resource, the redundant resource is recycled.

[0104] In the application, the resource type of the redundant resource is path resource and infrastructure resource, and the same matched resource as the emergency plan is found on the power communication network. The overlap of the redundant resource and the matched resource is compared to obtain the coverage rate of the redundant resource to the matched resource. When it is found that the coverage rate of the redundant resource to the matched resource can reach 100% or above, the reliability value of the redundant resource and the matched resource is compared. If the reliability value of the matched resource is low, the redundant resource is used to replace the matched resource. If the reliability value of the matched resource is high, the redundant resource is recycled. If there is data congestion in the path of the matched resource, the wireless transmission path in the redundant resource can be called to share the data transmission pressure of the congested path, or the congested path can be directly replaced.

[0105] The above are preferred embodiments of the application, and are not intended to limit the protection scope of the application. Any equivalent changes made on the basis of the structure, shape, and principle of the application should be covered by the protection scope of the application.
