Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a power communication fault repairing method according to an embodiment of the present invention.
The invention provides a power communication fault repairing method which is applied to a safety communication control center, wherein the safety communication control center is in communication connection with a communication emergency repair center, and the method comprises the following steps:
in the embodiment of the invention, the safety communication control center monitors the power communication state of each load node through the data of the load node forwarded by the network communication system, and if the power communication interruption of the load node is monitored, the safety communication control center acquires the fault data of at least one load node through the network communication system and provides a data basis for the subsequent power communication fault repairing sequence of the load node.

In one example of the present invention, before the secure communication control center performs power communication state monitoring of the load node, a TCP connection may be established with a preset network communication system by configuring virtual IP addresses of the secure communication control center and the network communication system. After the TCP connection is established, the network communication system receives a protocol communication request sent by the safety communication control center based on a connected protocol stack, and wakes up a plurality of sensors connected with the network communication system to collect power communication state data of the load nodes.
And after the network communication system receives the electric power communication state data corresponding to each load node, forwarding the electric power communication state data to the safety communication control center through the 5G communication network in a preset monitoring time period. And if the safety communication control center does not receive the power communication state data in the monitoring time period, judging that the power communication is interrupted at the moment.

Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks, capable of operating over a variety of communication systems that are hardwired to packet-switched or circuit-switched networks.
In another example of the present invention, the network communication system is further configured to,
responding to the protocol communication request, searching a target protocol library in a preset dynamic protocol library by adopting a protocol library identifier carried by the protocol communication request, and loading the target protocol library in a preset communication channel;
when fault data collected from load nodes by a plurality of preset sensors are received, carrying out protocol conversion on the fault data;
encapsulating the fault data after protocol conversion based on an MEC protocol to obtain primary encapsulated data;
and performing secondary encapsulation on the primary encapsulated data based on the SAA protocol and then sending the primary encapsulated data to a secure communication control center.
In this embodiment, after receiving the protocol communication request, the network communication system may search the target protocol library in the dynamic protocol library based on the protocol library identifier carried by the network communication system, and load the target protocol library in a general communication channel or other types of communication channels built in the network communication system. It should be noted that, a plurality of 5G communication protocols, such as 3GPP, LTE, CCSA, MEC, SAA, etc., are stored in the dynamic protocol library, and each communication protocol has a corresponding protocol library identifier.
After a target protocol library is loaded in a communication channel, unique identifiers of all sensors are distributed for communication signals, and the channel is initialized, so that subsequent data interactive transmission is realized. When the electric quantity communication fault of the load node is judged, fault data collected from the load node by a plurality of sensors is received through a network communication system, protocol conversion can be firstly carried out on the fault data for realizing subsequent high-speed data transmission, the fault data are converted into standard format data transmitted on a protocol adaptation layer of a 5G communication network, in order to guarantee the safety of data transmission, the fault data after protocol conversion can be packaged based on an MEC protocol to obtain primary packaging data, and the primary packaging data are subjected to secondary packaging based on an SAA protocol and then are sent to a safety communication control center.
Further, the target protocol library includes protocol description, protocol library identification, device type and configuration parameter information.

wherein f is the communication recovery time, ωiIs the load class, tiFor the communication recovery time, P, corresponding to the ith said load nodeiIs the average value of the active power corresponding to the ith load node, tpir is the ending time, tir is the starting time, N is the total number of the load nodes, F (t)maxIs the maximum value of the system function;
the optimal path time matrix is as follows:
Rreal(t)＝R*inc(t)；
wherein R isreal(t) is the optimal path time matrix, inc (t) is a preset optimal path increasing coefficient, and R is a preset positive integer.
In an example of the present invention, parameters such as a load level and an active power average value corresponding to each load node may be substituted into a preset global optimization formula, and the global optimization formula is solved with the objective of minimizing the communication recovery time of each load node, so as to obtain the communication recovery time corresponding to each load node.

In the embodiment of the invention, the power communication state data of each load node is acquired in real time through a network communication system and is forwarded to a communication safety control center, when the power communication state data is not received in a monitoring time period, the power communication is judged to be interrupted, at the moment, the communication safety control center can acquire fault data from a sensor of each load node through the network communication system, perform global optimization based on the fault data and determine the communication recovery time corresponding to each load node; sending each communication recovery time to a communication emergency repair center; the communication emergency repair center is used for generating a communication emergency repair scheme based on each communication recovery time. Therefore, the technical problem that the existing electric power communication network rush-repair process is lack of effective information safety protection measures to cause low rush-repair efficiency is solved, and based on the length of communication recovery time, a communication emergency rush-repair scheme corresponding to each load node is generated more efficiently, so that the rush-repair efficiency is improved, and the sustainable use of electric power communication is guaranteed.
