In the embodiment of the invention, the guaranteed-base power grid communication system is a software system and comprises a risk analysis model. The guaranteed-base power grid communication system obtains specified external environment data from the outside (such as an electric academy system), wherein the specified external environment data comprises but is not limited to typhoon data, icing data, thunder and lightning data, mountain fire data and municipal engineering data. And the bottom-protecting power grid communication system cleans the specified external environment data, generates effective data, and associates the effective data with the geographical position information of the optical cable section corresponding to the external environment data. The bottom-protecting power grid communication system combines effective data and geographical position information to form risk early warning information through a risk analysis model, wherein the risk early warning information comprises a disaster range, a risk level and reason analysis. And establishing a risk early warning processing mechanism for the guaranteed-base power grid communication system, and generating an accurate emergency plan according to risk early warning information when the risk influences the normal operation of the guaranteed-base communication network, so as to guide operation and maintenance personnel to guarantee the guaranteed-base communication network. Specifically, taking the protected-base communication network suffering from typhoon disasters as an example, the protected-base power grid communication system acquires grid data of typhoons from the electric academy of sciences system, and associates the grid data of the typhoons with the position information of the optical cable section. And the bottom-protecting power grid communication system combines the grid data and the position information of the optical cable section, and generates risk early warning information such as the disaster range, the risk level, the reason analysis and the like of the bottom-protecting communication network through a risk analysis model. When the risk level is larger than the preset standard, the guaranteed-base power grid communication system triggers a risk processing early warning mechanism, an emergency plan is generated according to risk early warning information, the content of the emergency plan comprises personnel allocation, resource sharing, first-aid repair plans and the like, the emergency plan is pushed to a home page of the guaranteed-base power grid communication system in a list form to be displayed, and meanwhile, corresponding communication operation and maintenance personnel are notified in a short message and mail form. Through the setting, when the guaranteed-end communication network is affected by a disaster, the guaranteed-end power grid communication system analyzes the influence of the disaster on the guaranteed-end power grid communication system, when the disaster affects the normal operation of the guaranteed-end communication network, operation and maintenance personnel can know the condition at the first time and generate an accurate emergency plan, the maintenance efficiency of the guaranteed-end power grid is improved, and the normal operation of the guaranteed-end communication network is guaranteed.
Referring to fig. 2, the step S1 of communicatively connecting the bottom-protected power grid communication system with the cable environment monitoring system, acquiring the designated external environment data affecting the operation of the bottom-protected communication network, and cleaning the designated external environment data to generate valid data includes:
s11: acquiring first external environment data from a cable environment monitoring system;
s12: capturing second external environment data from the internet through a crawler tool;
s13: and cleaning the first external environment data and the second external environment data to generate effective data.
In the embodiment of the present invention, the cable environment monitoring system is a system for detecting cable environment data in an electric department, and the monitoring content includes: typhoon data, icing data, lightning data and mountain fire data. The bottom-guaranteeing power grid communication system acquires typhoon data, icing data, thunder and lightning data and mountain fire data from the cable environment monitoring system through the Webservice interface. And carrying out intelligent analysis after the data are acquired, screening out fuzzy data, carrying out data duplication removal and conversion, and associating the meteorological data with the geographical position of the disaster-affected optical cable section through latitude and longitude. In addition, the bottom-guaranteed power grid communication system crawls municipal engineering information (including information such as construction types, construction names, construction ranges, construction time periods, construction states and the like) of a specified local city from a website by applying an internet visual crawler technology, and sets a timing task to perform incremental updating of data. Because the data crawled from the web contains much duplicative and useless information and is cluttered, further data deduplication, data cleansing, and data correlation are required. And judging the cleaned external environment data as effective data, and importing the effective data into a database of the bottom-protected power grid communication system for the bottom-protected power grid communication system to use. Through the arrangement, the disasters of the bottom-protection power grid communication system are divided into natural disasters and artificial disasters, and corresponding data are collected, so that the bottom-protection power grid communication system can respond to various disasters in time, and the application range of the bottom-protection power grid communication system is widened.
Referring to fig. 3 to 5, the step S3 of forming risk early warning information by the risk analysis model through the communication connection between the guaranteed-base power grid communication system and the optical cable online monitoring system includes:
s31, acquiring an alarm grade from the optical cable on-line monitoring system, wherein the alarm grade is alarm information generated by the optical cable on-line monitoring system monitoring the bottom-protected communication network;
s32, matching the alarm grade with a first preset risk grade criterion to generate a first risk grade;
s33, calculating a risk value according to the effective data;
s34, matching the risk value with a second preset risk grade criterion to generate a second risk grade;
and S35, comparing the first risk grade with the second risk grade, and judging the risk grade with higher risk as the risk grade of the guaranteed-base communication network.
In the embodiment of the invention, the optical cable on-line monitoring system is mainly used for monitoring the real-time operation state of the optical cable and carrying out optical cable. The risk information sources of the fault alarm bottom-guaranteeing communication network are two, firstly, the optical cable on-line monitoring system monitors the optical cable running state of the bottom-guaranteeing communication network and generates various types of alarms, and secondly, the bottom-guaranteeing power grid communication system acquires external environment data and generates the risk grade of the bottom-guaranteeing communication network through a risk analysis model, wherein the alarm types comprise port optical power alarm, optical cable interruption alarm, injection alarm, whole-course attenuation alarm, attenuation point alarm, reflectivity alarm and abnormal network element communication. The optical cable on-line monitoring system evaluates various types of alarms and generates corresponding alarm levels. And the bottom-protecting power grid communication system acquires an alarm grade from the optical cable on-line monitoring system, and matches the alarm grade with a first preset risk grade criterion to generate a first risk grade. If the guaranteed-base power grid communication system obtains the port optical power alarm from the optical cable on-line monitoring system, the alarm level of the alarm is four, referring to fig. 4, matching is performed according to a first preset risk level criterion, the guaranteed-base power grid communication system generates a first risk level, and the level value of the first risk level is three. In addition, referring to fig. 3, the guaranteed-base power grid communication system calculates a risk value according to the valid data, and generates a second risk level according to a second preset risk level criterion. If the risk value calculated by the guaranteed-base power grid communication system is 10, the risk level of the guaranteed-base communication network is a first level, wherein the risk levels of the guaranteed-base and the communication network are from low to high and comprise a third level (attention), a second level (early warning) and a first level (disposal); the third level (attention) represents that the risk value of the optical cable reaches a certain height, and the attention of communication operation personnel and the online monitoring frequency of the optical cable need to be enhanced; the second-level (early warning) represents that the risk value is high and is possibly converted into the first-level risk, communication operating personnel are required to be in a warning state, and meanwhile, the on-line monitoring frequency of the optical cable is required to be adjusted upwards and is higher than that of the third-level; the first-level (disposal) indicates that the emergency such as optical cable interruption or imminent optical cable interruption damaging the operation stability of the bottom-protected communication network needs communication operation and maintenance personnel to perform emergency treatment immediately, and the monitoring frequency of the optical cable on-line monitoring system is set to be the highest in the highest standby state. And the bottom-guaranteed power grid communication system judges the first risk level and the second risk level, and judges the risk level with higher risk as the risk level of the bottom-guaranteed communication network. And if the first risk level is three levels and the second risk level is one level, the risk level of the bottom-guaranteed communication network is one level. Through the arrangement, the operation risk of the bottom-protected communication network can be analyzed according to the environmental data by the bottom-protected power grid communication system, and the operation risk information of the bottom-protected communication network can be acquired from the optical cable on-line monitoring system to be supplemented, so that the analysis of the operation risk of the bottom-protected communication network by the bottom-protected power grid communication system is more accurate.
Further, the step S33 of calculating a risk value according to the valid data includes:
s331: acquiring a current environment data value, a disaster risk design value and an optical cable coefficient, wherein the current environment data value is the current environment data value acquired by a guaranteed-base power grid communication system, and the disaster risk design value is the historical maximum value of disaster environment data of an area where a guaranteed-base communication network is located;
s332: and calculating the risk value according to the current environment data value, the disaster risk design value and the optical cable coefficient.
In the embodiment of the invention, different types of environment data have different formulas for calculating the risk value.
For example, the typhoon risk value calculation formula is:
k (Current wind speed-design wind speed)/design wind speed-formula 1
The data acquired from the electric academy system is grid data of wind speed, the grid data is associated with the position information of the optical cable section, and the highest value of the grid data when typhoon passes is taken as the current wind speed in the formula 1 in the embodiment. In addition, the design wind speed in equation 1 is the maximum value of the typhoon wind speed experienced by the area over the years, and K is an internally defined cable coefficient (cable types include duct cable, OPGW, ADSS, which is different according to the degree of the cable affected by the typhoon).
For example, the risk value of icing is calculated by the formula:
k1 (Current icing thickness-design icing thickness)/design icing thickness-equation 2
An ice coating value is obtained from the electric academy system and is associated with the optical cable in position, and the ice coating value is used as the current ice coating thickness in the formula of the embodiment. In formula 2, K1 is an internally defined ice coating coefficient, and is different according to whether the ice melting device is installed on the cable.
For example, the calculation formulas for lightning, mountain fire, municipal works:
M.K 2-equation 3
Acquiring central points and coverage ranges of thunder and lightning and mountain fire from an electric academy system, judging the optical cable segment influenced by the lightning strike and the mountain fire according to the distance, and calculating the distance M1 between the optical cable segment and the central points of the thunder and the mountain fire; after the municipal construction information crawled from the website is processed, a construction area is defined on a map, and the vertical distance M2 from the optical cable section to the construction section is calculated. K2 is the internal definition coefficient, has different values according to the type difference of thunder and lightning/mountain fire/municipal works, only needs to substitute corresponding M and K2 into formula 3 when calculating the risk value of thunder and lightning, mountain fire, municipal works.
Through the setting, the guaranteed-end power grid communication system calculates the corresponding risk level according to different types of external environment data, and the accuracy of risk analysis of the guaranteed-end communication network is improved.
Referring to fig. 6 and 10, the step S4 of establishing a risk early warning processing mechanism by communicatively connecting the warranty power grid communication system and the risk emergency system, and generating an emergency plan according to the risk early warning information includes:
s41: judging whether the risk level of the bottom-protected communication network reaches a preset standard or not;
s42: if so, sending the risk early warning information to a risk emergency system;
s43: and receiving an emergency plan which is transmitted back to the guaranteed-base power grid communication system by the risk emergency system, wherein the emergency plan is plan information generated by the risk emergency system according to the risk early warning information.
In the embodiment of the invention, whether the risk level of the bottom-protected communication network reaches the preset standard or not is judged, and if yes, the risk early warning information is sent to the risk emergency system. And the insurance bottom power grid communication system receives the emergency plan which is transmitted back to the insurance bottom power grid communication system by the risk emergency system. For example, when the risk level of the guaranteed-base communication network is two or more levels, the guaranteed-base power grid communication system sends the risk early warning information to the risk emergency system, the risk emergency system performs risk analysis and judgment according to an internal mechanism and generates an emergency plan, and the risk emergency system transmits the document of the emergency plan back to the guaranteed-base power grid communication system, wherein the emergency plan comprises information such as risk points, personnel material arrangement, fault handling arrangement and the like. In other embodiments of the present invention, when the risk level of the guaranteed infrastructure communication network does not reach the preset standard, the guaranteed infrastructure communication system does not generate an emergency plan. Through the arrangement, the bottom-guaranteeing power grid communication system generates the emergency plan only when the risk of the bottom-guaranteeing communication network influences the normal operation of the bottom-guaranteeing communication network, and the emergency plan is not generated at risk, so that the resource allocation is reasonable, and unnecessary loss of manpower and resources is reduced.
Further, after step S4 of establishing a risk early warning processing mechanism and generating an emergency plan according to the risk early warning information, the method includes:
s5: and sending the optical cable state acquisition instruction information to an optical cable on-line monitoring system.
In the embodiment of the invention, after the bottom-protected power grid communication system generates the emergency plan, the optical cable state acquisition instruction information is sent to the optical cable on-line monitoring system. The optical cable on-line monitoring system acquires the real-time state information of the optical cable to confirm the actual running state of the optical cable, so that the bottom-guaranteed power grid communication system acquires the running state of the optical cable in real time.
Referring to fig. 7, the present invention provides a device for analyzing operational risk of a guaranteed-base communication network, including:
the system comprises an acquisition module 1, a data processing module and a data processing module, wherein the acquisition module is used for acquiring specified external environment data which influence the operation of a bottom-preserving communication network, cleaning the specified external environment data and generating effective data;

In the embodiment of the invention, the guaranteed-base power grid communication system is a software system and comprises a risk analysis model. The guaranteed-base power grid communication system obtains specified external environment data from the outside (such as an electric academy system), wherein the specified external environment data comprises but is not limited to typhoon data, icing data, thunder and lightning data, mountain fire data and municipal engineering data. And the bottom-protecting power grid communication system cleans the specified external environment data, generates effective data, and associates the effective data with the geographical position information of the optical cable section corresponding to the external environment data. The bottom-protecting power grid communication system combines effective data and geographical position information to form risk early warning information through a risk analysis model, wherein the risk early warning information comprises a disaster range, a risk level and reason analysis.
