In the case of evaluating the service damage in step 2), if a certain service channel has protection and the protection is confirmed to be valid after checking the protection switching event, the operation of the service channel is not affected by the fault; otherwise, the service channel is interrupted, and the service channel is added into the damaged service channel set.
In the step 2) of evaluating the service damage condition, sequentially evaluating the influence of service channel interruption in the damaged service channel set on the service in the service set to be evaluated, if a certain service has a hot standby service channel outside the damaged service channel set, the service is not damaged in operation; if a certain service has a cold standby service channel outside the damaged service channel set, the service is damaged in operation, and the service is added into the damaged service set; if a certain service does not have a service channel outside the damaged service channel set, the service is judged to be interrupted, and the service is added into the interrupted service set.
In the service grooming scheme generated in step 3), for the damaged service set with the cold standby channel, a service grooming scheme for switching the service to the cold standby channel is generated.
In the step 3) of generating the traffic grooming scheme, for an interrupted traffic set without a backup channel, a traffic detour route set for avoiding a fault resource is listed according to a path search algorithm, an optimal weight of each traffic detour route is calculated, and finally, an optimal traffic detour route is adopted to generate the traffic grooming scheme.
In the service grooming scheme generated in step 3), the preferred weight of each service detour route is calculated according to the type of the optical cable carrying the detour route, the length of the optical cable, the operation time, the voltage level, the bandwidth utilization rate of the detour route, and the number of important services carried.
In the step 4), the service grooming scheme is executed, and a service rush-to-talk process or a temporary mode process is started according to the service grooming scheme generated in the step 3), so that the rush-to-talk of the damaged service is completed.
The technical effects obtained by the invention are as follows:
the method for quickly preemptively accessing the electric power communication network service provided by the invention can quickly analyze and evaluate the real damage condition of the service and specifically make a reasonable corresponding service preemptive scheme after the electric power communication network fails, and finally promptly preemptively access the service so as to avoid causing larger negative influence on the safe and stable operation of a primary system of a power grid.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes in detail a method for quickly preempting power communication network services provided by the present invention with reference to an embodiment.
Example one
The invention provides a quick emergency call method for electric power communication network service, which comprises the following steps: establishing a service bearing model, evaluating the service damage condition, generating a service grooming scheme and executing the service grooming scheme.
Firstly, establishing a service bearing model
The premise and the foundation of the invention are to establish a bearing model of network resources to services. The model is established by increasing the bearing relationship of network resources to service channels and the bearing relationship of the service channels to services on the basis of the traditional network resource model.
Secondly, evaluating the service damage condition
When a fault in the power communication network is monitored, a service damage assessment process is actively initiated, and the specific steps are as follows:
1) and searching all service channels borne by the fault resources according to the service bearing model, and adding the found service channels into a service channel set C1 to be evaluated.
2) Sequentially evaluating the influence of the fault on the service channels in the set C1, and if the protection exists in a certain service channel and the protection is confirmed to be effective after the protection switching event is checked, the operation of the service channel is not influenced by the fault; otherwise, the service channel is interrupted, and the service channel is added into the damaged service channel set C2.
3) And searching all services carried by the channels in the damaged service channel set C2 according to the service carrying model, and adding the found services into the service set S1 to be evaluated.
4) Sequentially evaluating the influence of service channel interruption in the set C2 on the service in the set S1, if a certain service has a hot standby service channel outside the set C2, the service is not damaged; if a certain service has a cold standby service channel outside the set C2, the service is damaged in operation, and the service is added into a damaged service set S2; if a service does not have a service channel except the set C2, the service is judged to be interrupted, and the service is added into an interrupted service set S3.
Thirdly, generating a service grooming scheme
When the set S2 of the traffic impairment evaluation results is not empty, a traffic grooming scheme is automatically generated for each traffic in the set S2, where the grooming scheme is to switch traffic to the cold standby traffic channel.
When the set S3 of the traffic impairment evaluation results is not empty, a traffic grooming scheme is generated for each traffic in the set S3 in sequence according to the following steps:
1) according to the characteristics of the starting point, the end point, the bandwidth and the like of the service, a service roundabout route set P1 for avoiding the fault resource is found in the service bearing model by utilizing a path search algorithm.
2) Comprehensively considering parameters such as the type of an optical cable bearing the roundabout route, the length of the optical cable, the operation life, the voltage level, the bandwidth utilization rate of the roundabout route, the number of the loaded important services and the like, and calculating the priority value of each service roundabout route in the set P1; and selecting the optimal service alternative route from the set P1 according to the priority value to generate a service grooming scheme.
Fourth, executing business grooming scheme
And according to the generated service grooming scheme, quickly starting a service rush-to-pass flow or a temporary mode flow to finish the rush-to-pass of the damaged service.
The present invention is described in detail with reference to the embodiments, but the present invention is not limited to the above embodiments, and any improvements and modifications made to the present invention are within the scope of the claims of the present invention.
