[0059] The embodiments of the present invention provide a loop filling method, device, equipment and medium for a power grid communication system, which are used to solve the technical problems that existing optical cable looping methods, main network looping methods, etc., have the risk of external optical cable damage and cannot improve the stability of the power grid communication system.

[0060] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0061] See also Figure 1 , Figure 1 A flowchart of a loop filling method for a power grid communication system provided by an embodiment of the present invention.

[0062] The present invention provides a loop filling method for a power grid communication system, which is applied to the power grid communication system and includes:

[0063] Step 101: respond to a grid communication loop filling request and obtain a communication topology diagram corresponding to the grid communication system.

[0064] The power grid communication system refers to the communication link composed of multiple power room switches and terminals.

[0065] A power grid communication loop filling request refers to an analysis request issued by operation and maintenance personnel to find the best node for filling the power grid communication system loop.

[0066] The communication topology diagram refers to the abstraction of power room switches and terminals in the power grid communication system into nodes, and the abstraction of optical cable lines into lines, which are represented in the form of a topology diagram.

[0067] In an embodiment of the present invention, a communication topology diagram corresponding to the power grid communication system is obtained in response to a parsing request for an optimal ring filling node of the power grid communication system.

[0068] Step 102: Determine whether the communication topology is a multi-branch topology.

[0069] A multi-branch topology diagram refers to a communication topology diagram with at least two branch links.

[0070] In the embodiment of the present invention, it is determined whether the communication topology graph has at least two branch links.

[0071] Step 103: If the communication topology is a multi-branch topology, any two non-adjacent communication nodes in the communication topology are selected for connection to generate multiple complementary ring communication topologies.

[0072] The ring filling communication topology diagram refers to selecting any two non-adjacent communication nodes from the communication topology diagram and connecting them, thereby simulating the situation of filling the ring through any two adjacent power room switches on the power grid communication system in the form of a topology diagram.

[0073] In an embodiment of the present invention, if the communication topology graph has at least two branch links, any two non-adjacent communication nodes in the communication topology graph are selected for connection to generate multiple ring-complementing communication topologies.

[0074] Step 104 : Determine the impact value corresponding to the patch ring communication topology diagram according to the patch ring communication topology diagram and a preset impact analysis model.

[0075] In an embodiment of the present invention, a patching ring communication topology graph is input into a pre-trained influence analysis model, wherein the influence analysis model includes a patching ring node marking network and an influence value analysis network. Any two non-adjacent communication nodes in the communication topology graph are selected through the patching ring node marking network for connection to generate multiple patching ring communication topology graphs. Then, any communication node in the patching ring communication topology graph is selected as a target node, and the communication link associated with the target node is feature-marked to generate multiple influence feature graphs. The influence feature graph is input into the influence value analysis network to generate node influence values ​​corresponding to the influence feature graphs. All node influence values ​​are summed to generate a first sum value. A first ratio of the first sum value to the number of communication links in the patching ring communication topology graph is calculated, and the first ratio is determined as the influence value corresponding to the patching ring communication topology graph.

[0076] Step 105: Select the ring-filling communication topology with the largest impact value as the target topology, and perform a ring-filling operation on two communication nodes corresponding to the target topology.

[0077] In the embodiment of the present invention, the ring-filling communication topology with the largest influence value is selected from multiple ring-filling communication topologies as the target topology, and the ring-filling operation is performed on two communication nodes in the target topology that are different from the communication topology.

[0078] It should be noted that if the required number of ring filling is multiple, the ring filling communication topology with the largest influence value and the ring filling communication topology with the second best value are selected as the target topology, and the two communication nodes corresponding to the target topology are subjected to the ring filling operation.

[0079] In an embodiment of the present invention, a request for parsing the optimal ring-filling node of a power grid communication system is responded to, a communication topology corresponding to the power grid communication system is obtained, and it is determined whether there are at least two branch links in the communication topology. If there are at least two branch links in the communication topology, any two non-adjacent communication nodes in the communication topology are selected for connection to generate multiple ring-filling communication topologies. Based on the ring-filling communication topologies and a preset impact analysis model, the impact values ​​corresponding to the ring-filling communication topologies are determined, and the ring-filling communication topology with the largest impact value is selected as the target topology. The two communication nodes corresponding to the target topology are subjected to a ring-filling operation. This solves the technical problem that existing optical cable ringing and main network ringing methods have the risk of external optical cable damage and cannot improve the stability of the power grid communication system. This method realizes signal ring-filling of star-shaped communication links, avoids the inability of subsequently connected nodes to communicate due to the failure of a node. By using the impact analysis model to analyze multiple ring-filling communication topologies that simulate ring-filling situations, the optimal ring-filling connection point in the communication topology is found, thereby improving the stability of the power grid communication system.

[0080] See also Figure 2 , Figure 2A flowchart of a loop filling method for a power grid communication system provided by an embodiment of the present invention.

[0081] The present invention provides a loop filling method for a power grid communication system, which is applied to the power grid communication system and includes:

[0082] Step 201: respond to a grid communication loop filling request and obtain a communication topology diagram corresponding to the grid communication system.

[0083] In an embodiment of the present invention, a communication topology diagram corresponding to the power grid communication system is obtained in response to a parsing request for an optimal ring filling node of the power grid communication system.

[0084] Step 202: Determine whether the communication topology is a multi-branch topology.

[0085] In the embodiment of the present invention, it is determined whether the communication topology graph has at least two branch links.

[0086] Furthermore, the method further comprises the steps of:

[0087] S11. If the communication topology is a single-link topology, two communication nodes at the beginning and the end of the communication topology are selected as second ring complement nodes.

[0088] In the embodiment of the present invention, please refer to Figure 3-4 As shown in the figure, if there is only one link in the communication topology, then Figure 3 The single-station link in Figure 4 In the dual-station links, the two communication nodes at the head end and the end end in the communication topology diagram are selected as the second complementary ring nodes.

[0089] It should be noted that Figure 3-4 In the figure, the communication node represents the location of the interactive machine in the power distribution room.

[0090] S12. Obtain communication strength values ​​between the second complementary ring nodes.

[0091] In an embodiment of the present invention, a power grid communication system sends an instruction to query the communication strength value between the second ring patch nodes.

[0092] It should be noted that before obtaining the communication strength value between the second complementary ring nodes, the position of the single link is also found.

[0093] S13: Determine whether the communication strength value is greater than or equal to a preset communication threshold.

[0094] The communication threshold refers to the signal strength value when the switch is running stably, which is generally 0.2FF.

[0095] In the embodiment of the present invention, it is determined whether the communication strength value is greater than or equal to the signal strength value of the switch during stable operation.

[0096] S14: If the communication strength value is greater than or equal to the communication threshold, perform a ring filling operation on the second ring filling node.

[0097] In the embodiment of the present invention, if the communication strength value is greater than or equal to the signal strength value of the switch during stable operation, the second ring patching node is subjected to a ring patching operation.

[0098] S15. If the communication strength value is less than the communication threshold, mark the second patching ring node as a failed node, determine a new second patching ring node from the communication nodes adjacent to the second patching ring node, and jump to the step of obtaining the communication strength value between the second patching ring nodes.

[0099] A failed node refers to a communication node that cannot perform ring patching operations.

[0100] In this embodiment of the present invention, if the communication strength value is less than the signal strength value of the switch during stable operation, the second patching ring node is marked as a failed node, and the previous adjacent communication node of the second patching ring node is determined as a new second patching ring node, and the process jumps to the step of obtaining the communication strength value between the second patching ring nodes.

[0101] Step 203: If the communication topology is a multi-branch topology, any two non-adjacent communication nodes in the communication topology are selected for connection to generate multiple complementary ring communication topologies.

[0102] In the embodiment of the present invention, see Figure 5 As shown, if there are at least two branch links in the communication topology, any two non-adjacent communication nodes in the communication topology are selected to connect to generate multiple complementary ring communication topologies.

[0103] Step 204: Select any communication node in the ring-filling communication topology diagram as a target node, perform feature marking on the communication link associated with the target node, and generate multiple impact feature diagrams.

[0104] The target node refers to the communication node that simulates the fault in the power grid communication system.

[0105] In an embodiment of the present invention, any communication node in the ring-filling communication topology diagram is selected as a target node to simulate a line fault, and characteristic marking is performed on the communication link associated with the target node to generate a plurality of impact characteristic diagrams.

[0106] Step 205: Input the impact characteristic graph into a preset impact analysis model to generate a node impact value.

[0107] In an embodiment of the present invention, the influence characteristic graph is input into a preset influence analysis model to generate a node influence value.

[0108] In a specific implementation, the impact analysis model can be improved and trained by selecting any one of the models such as convolutional neural networks CNN (Convolutional Neural Networks), regional convolutional neural networks R-CNN (Region with CNN Feature), Faster R-CNN (FasterRegion with CNN Feature), Mask R-CNN (Mask Region with CNN Feature), GraphSAGE, etc., which is not limited in this embodiment.

[0109] In a preferred implementation, the impact analysis model in this embodiment can be improved and trained by CNN. The traditional CNN model generally adopts the ResNet-FPN architecture for feature extraction, but the impact analysis model in this embodiment only includes 1 feature extraction network, 2 pooling layers and a fully connected layer. The feature extraction network is composed of a 1*1 standard convolution layer, a first convolution layer, a second convolution layer, an activation function layer and a 1*1 standard convolution layer connected in sequence. In the first convolution layer, the kernel size is 9*9 and the input channel is 1, the output channel is 16, the stride is 1, and the padding is 1. In the second convolution, the kernel size is 3*3, the input channel is 16, the output channel is 32, the stride is 1, and the padding is 1. The pooling layer is 3*3 maximum pooling, and the fully connected layer is 32*(L / 4)*(L / 4)*1. The activation function layer of the model is the ReLU function. The improved CNN model can more accurately calculate the corresponding node influence value in the influence feature map, and compared with the existing lightweight network, it can identify and analyze the influence feature map faster and reduce latency.

[0110] In a preferred implementation method, all distribution room interaction machine Pi signals are first measured, and the distribution room nodes are marked as PAi. The distribution room nodes are connected in pairs, and the number of computer rooms affected under different interruption depths is calculated. The distribution room nodes are constructed into a training set, and the corresponding number of affected computer rooms is set as the affected sample label. The training set and the corresponding affected sample label are input into the preset impact analysis model for training, and during the training process, any one or more combination strategies of gradient descent, gradient accumulation, schedule and gradient clipping are introduced to optimize the model parameters for training.

[0111] In the specific implementation of this embodiment, first, the training set (generating feature matrices and labels for all communication nodes) is used to train the improved CNN model, and then any network is selected to generate feature matrices for all unlabeled communication nodes. The impact feature map is then input into the trained impact analysis model to generate the node impact value corresponding to the impact feature map.

[0112] Step 206: sum up all node influence values ​​to generate a first sum value.

[0113] In the embodiment of the present invention, the node influence values ​​in all cases are summed to generate a first sum value.

[0114] Step 207: perform ratio processing on the first sum value and the number of communication links in the complementary ring communication topology diagram to generate an influence value corresponding to the complementary ring communication topology diagram.

[0115] In the embodiment of the present invention, a first ratio between the first sum and the number of communication links of the complementary ring communication topology is calculated, and the first ratio is determined as the influence value corresponding to the complementary ring communication topology.

[0116] Step 208: Select the ring-filling communication topology with the largest impact value as the target topology, and perform a ring-filling operation on the two communication nodes corresponding to the target topology.

[0117] Furthermore, step 208 includes the following sub-steps:

[0118] S21. Determine two communication nodes corresponding to the target topology graph as first complementary ring nodes.

[0119] In the embodiment of the present invention, wireless gateways are deployed on two communication nodes corresponding to the target topology graph and are determined as first ring patching nodes.

[0120] It should be noted that the wireless gateway is primarily used to connect two different distribution room networks. It also enables simultaneous communication with the switches in both distribution rooms. However, the switches cannot communicate directly; they must communicate through the wireless gateway. The wireless gateway operates at the application layer.

[0121] S22. Select any one of the two first complementary ring nodes as the initiating end, and the other first complementary ring node as the terminating end.

[0122] In the embodiment of the present invention, after the wireless mesh is laid out at the first patching ring nodes, any one of the two first patching ring nodes is selected as the initiating end, and the other first patching ring node is selected as the terminating end.

[0123] S23. Obtain the channel identifier of the terminating end through the initiating end.

[0124] In the embodiment of the present invention, the channel identifier of the terminating wireless gateway is obtained by the initiating wireless gateway.

[0125] It should be noted that the channel identifier is a 32-bit channel identifier.

[0126] S24. Compare the channel identifier with the preset port permission table.

[0127] The port permission table refers to a data list consisting of multiple port identifiers.

[0128] In the embodiment of the present invention, the channel identifiers are matched one by one with the port identifiers in the preset port permission table.

[0129] S25. If the comparison result of the channel identifier and the port permission table is consistent, the channel identifier of the terminating end is modified to be consistent with the channel identifier of the initiating end.

[0130] In the embodiment of the present invention, when the channel identifier is compatible with any port identifier, the channel identifier of the terminating end is modified to be consistent with the channel identifier of the initiating end.

[0131] It should be noted that, when the channel identifier does not match any port identifier, an alarm signal is sent to the initiating end, and a prompt is given that the current terminating end is not compatible with the initiating end.

[0132] It should be noted that only when the channel identifiers of the initiating end and the terminating end are consistent can the two establish a data channel.

[0133] S16. Establish a data channel between the initiating end and the terminating end.

[0134] In the embodiment of the present invention, a GRE data channel is established between the initiating end and the terminating end, so that the interactive machine protocol changes from layer 3 to layer 2, allowing the STP signal of the distribution room switch and the interactive machine layer 2 data packet to pass.

[0135] In an embodiment of the present invention, in response to a request for parsing the optimal ring patching node of a power grid communication system, a communication topology corresponding to the power grid communication system is obtained, and a determination is made as to whether the communication topology contains at least two branch links. If so, any two non-adjacent communication nodes in the communication topology are selected for connection, generating multiple ring patching communication topologies. Based on the ring patching communication topologies and a preset impact analysis model, the impact values ​​corresponding to the ring patching communication topologies are determined. The ring patching communication topology with the largest impact value is selected as the target topology, and a ring patching operation is performed on the two communication nodes corresponding to the target topology. This solves the technical problem that existing optical cable ringing and main network ringing methods, such as those with the risk of external optical cable damage, cannot improve the stability of the power grid communication system. This method implements signal ring patching for star-shaped communication links, preventing the failure of a single node from causing communication loss among subsequently connected nodes. By analyzing multiple ring patching communication topologies simulating ring patching scenarios using an impact analysis model, the optimal ring patching connection point in the communication topology is found. This allows the routing protocol of the distribution room switch to automatically switch to another line for connection when the original link is damaged, thereby improving the stability of the power grid communication system.
