And selecting one piece of overhaul task information, analyzing the resource related to the overhaul task information, analyzing the influence range and the influence degree of the resource during overhaul, and prompting whether the interrupted business can detour if the service is interrupted during the overhaul of the resource. The influence scope refers to which services are influenced when the resource is overhauled; the influence degree refers to whether the influence business is influenced or interrupted when the resource is overhauled.

Meanwhile, a plurality of overhaul task information is analyzed, whether the start time and the finish time of the overhaul task information are overlapped or not is analyzed, if so, the resources related to the overlapped overhaul task information are analyzed, the influence range and the influence degree are analyzed, if the service is interrupted, whether the interrupted service can detour or not is prompted, meanwhile, the unreasonable time arrangement of the overlapped overhaul task information is prompted for a user, the start time and the finish time of the overhaul task information are suggested to be changed, and the execution is staggered.
The results of the multitasking preview simulation are presented based on the network topology.
The multi-task overhaul pre-modeling simulation function entrance is to select a plurality of pieces of overhaul task information in an overhaul task list for overhaul pre-modeling simulation analysis.
Thirdly, according to the association relation between the overhaul task information and the equipment and the optical cable, corresponding faults are set in a simulation mode, and the faults are spread and spread on the network topology and the running state;
As shown in fig. 2, a user selects a fault type and a fault cause on a designated device or optical cable resource, then generates a fault, activates the fault, then generates a fault alarm, and simulates and presents a scene of fault diffusion and propagation on the network topology and the operation state.
(1) The generation of faults comprises two modes of manual entry and fault synchronization.
1) Manual entry
The user is supported to manually set fault points for the simulation resources, and one or more fault sources can be set. And after the fault is activated, alarm information is generated according to the fault, the situation that the fault propagates in the network is simulated, and the situation is presented on the network topology and the running state. The input mode is as follows:
a. Selecting a certain optical cable resource on the optical cable topology level, selecting 'fault simulation', and popping up a fault setting interface, wherein the attributes in the interface at least comprise: emulation cable resources (e.g., cable or fiber, cannot be modified), emulation time, failure cause (drop down list selection), failure type (drop down list selection), failure name, operator, remark field, and save, activate, reset buttons.
B. Selecting a certain device on the device topology level, selecting 'fault simulation', and popping up a fault setting interface, wherein the attributes in the interface at least comprise: simulation equipment resources (such as equipment, optical boards, branch boards, optical ports and electric ports, pull-down selection), simulation time, fault reasons (pull-down list selection), fault types (pull-down list selection), fault names, operators and remark fields, and save, activate and reset buttons.
The triggering mode is as follows:
a. a single trigger. The 'activation' button is directly clicked to trigger a single fault, and simultaneously, alarm information is generated and dynamically presented on the network topology and the running state.
B. And triggering in batches. And selecting unactivated faults in the fault list to activate in batches, generating alarm information at the same time, and dynamically presenting the alarm information on network topology and running state.
2) Configuring fault alarms and rules
And maintaining a fault alarm rule table, wherein each excitation model corresponds to a group of alarm rules, and the alarm rules at least comprise root alarms. The director role user performs adding, deleting and modifying operations on the alarm rule. The alarm rules should be distinguished according to the equipment manufacturers, and each fault should be configured with at least the root alarm rules of all the equipment manufacturers. The transmission rule of the fault alarm is as follows:
a. the multiplex section alarm is transmitted on the multiplex section and appears at the end point of the multiplex section.
B. The higher order alarms are all propagated downstream and appear on each station of the higher order channel until the higher order channel end point is terminated.
C. low-order alarms are transparently passed on low-order channels, but typically occur when up and down (source and sink of the channel).
For example, an LOS/LOF alarm may derive the MS-RDI, the derivation of which is shown in FIG. 3. TU-LOP/TU-AIS alarms may derive an LP_RDI alarm as shown in FIG. 4.

A high level alarm above the arrow will mask a low level alarm downstream of the arrow. In this way, when locating a fault, attention can be focused on a high level of alarms first. Meanwhile, the generation of fault alarms should also have a learning function. Over time, the managed network device may continuously present new fault types, new fault messages, and new service obstacles, and expandability is a key feature of the alarm management and fault management system, and requires that new and valid association rules be continuously discovered, and meanwhile, association rules that have been discovered before but have failed are removed.
The director role user clicks the menu 'simulation behavior model', 'alarm suppression rule maintenance' in turn, enters an alarm suppression rule maintenance interface, displays all alarm suppression rules and 'new' buttons on the interface, clicks the 'new' button, pops up the alarm suppression rule addition interface, and the attribute field on the interface at least comprises: an upstream alarm name (selection tree), a suppression alarm name (selection tree), remarks. The right key selects a record for modification and deletion operations.
The director role user clicks the menu ' simulation behavior model ' -fault alarm configuration ' in turn to enter a fault alarm configuration interface, the interface displays various fault types, resource names, alarm configuration records among equipment manufacturers (namely, fault alarms are uniquely determined by simulation resources and fault types) and ' newly added ' buttons, clicks the newly added buttons, pops up the newly added fault alarm configuration interface, and attribute fields on the interface at least comprise: fault type (drop down list), resource name (site, cable, fiber, equipment, light board, branch board, light port, electrical port, drop down selection), alarm manufacturer (drop down list), alarm name (selection tree), etc.
(3) Simulation result display

Therefore, the fault simulation result is mainly shown in the running state and the network topology.

The maintenance preview simulation result display is used for supporting the results of the single-task maintenance preview simulation and the multi-task maintenance preview simulation, and the maintenance preview simulation result is displayed based on the network topology. The display requirements are as follows:
in the network topology with the connection type of service, the affected degree of the service is distinguished by the color of the line, the yellow service is affected, the red service is interrupted, and the display is performed in the form of characters on the line. For example, stations a to B carry 2 relay protection services, 10 comprehensive data network services, overhaul results in interruption of 1 relay protection service, and 5 comprehensive data network services are affected. The presentation is performed as follows:
And marking optical cable and equipment resources involved in the overhaul preview simulation by using the identification of the wrench in the network topology. The service is selected, the route information of the service can be directly displayed in the topological graph, and the main and standby routes are identified by different colors. After the inspection and previewing simulation analysis is completed, the analysis result is displayed on the topological graph in a floating mode in a diagram mode, the displayed content comprises interrupted service statistics and affected service statistics, and meanwhile the interrupted service detourable statistics are displayed. Clicking on the statistics may view detailed list information.
