[0064] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0065] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in one or more embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0066] The technical solutions of the present disclosure are further described in detail below through specific embodiments.

[0067] In one aspect, an embodiment of the present application provides a method for preventing mislocking of a substation system.

[0068] like Figure 1 As shown, one or more optional embodiments of the present application provide a method for preventing mislocking of a substation system, comprising:

[0069] S1: Obtain equipment information of the substation system, and create a ladder diagram based on the equipment information.

[0070] The device information includes device status signals, device action signals, device measurement value signals, and anti-mislocking condition signals of multiple devices in the substation system.

[0071] The ladder diagram can be created based on the device status signals, device action signals and other status quantity signals of each device in the substation system, as well as the device measurement signals (such as electrical measurement values, etc.) and the anti-mislocking condition signals sent by other devices received through the station control layer network or hard wiring as graphic elements in the ladder diagram.

[0072] like Figure 2 , which is an exemplary ladder diagram created based on the equipment information in the substation system. In some optional embodiments, the overall input and output of the ladder diagram corresponding to the substation system are also considered as a graphic element and reflected in the ladder diagram.

[0073] S2: Extracting data on the connection relationship between each pair of graphic elements in the ladder diagram and constructing a data structure.

[0074] In the ladder diagram, the AND or OR logical relationships between multiple devices in the substation system are represented by parent-child and sibling relationships between the graphics elements. A data structure corresponding to each graphics element can be determined based on the parent-child and sibling relationships between the multiple graphics elements. The data structure can include the corresponding graphics element's name information, a list of parent and child nodes, graphics element node attribute information, and other relevant remarks.

[0075] S3: Simplify the data structure and determine an anti-error locking logic expression.

[0076] The data structure corresponding to the graphic element contains information related to the logical connection relationship between multiple graphic elements. By comprehensively considering the data structures corresponding to multiple graphic elements and simplifying the contents of the data structures, the anti-mislocking logic expression corresponding to the entire ladder diagram can be determined.

[0077] In some optional embodiments, the graphic elements can be used as tree nodes, and the node relationship data corresponding to the graphic elements can be used as the node data of the tree nodes. The connection relationship between multiple tree nodes is determined based on the parent-child relationship and sibling relationship between multiple graphic elements, so as to convert the ladder diagram into a logical relationship tree. The overall input graphic element of the ladder diagram corresponds to the root node of the logical relationship tree, and the overall output graphic element corresponds to the terminal node of the logical relationship tree. The data structure can be simplified by simplifying the tree structure.

[0078] S4: performing anti-error locking monitoring on the substation system according to the anti-error locking logic expression.

[0079] A rule file for locking logic judgment may be generated according to the anti-error locking logic expression, and then the rule file may be used to perform anti-error locking monitoring on the substation system.

[0080] The proposed method for preventing mislocking in a substation system creates a ladder diagram based on the substation system's equipment information, extracts and analyzes the logical dependencies between the various elements in the ladder diagram to determine the corresponding node data. Based on this node data, each element is converted into a logical relationship tree for analysis and simplification, resulting in a compact and accurate logical expression for monitoring against mislocking. This method efficiently and quickly generates accurate and simplified locking logic expressions, even for highly complex substation systems, making them easy to understand and apply.

[0081] like Figure 3 As shown, in a method for preventing mislocking of a substation system provided by one or more optional embodiments of the present application, extracting data on the connection relationship between each pair of elements in the ladder diagram and constructing a data structure includes:

[0082] S301: Determine the node name of the graphic element according to the identification name of the graphic element.

[0083] The identification name can be determined based on the device name of the corresponding device of the graphic element, or identity IDs can be assigned to multiple graphic elements in the ladder diagram, and the identity IDs are used as identification names to determine the node names. Figure 2 As shown, the node names corresponding to the multiple graphic elements can be Input, Output, or A, B, C...

[0084] S302: Determine the node data content of the graphic element according to the device information corresponding to the graphic element.

[0085] S303: Determine the parent node list and the child node list of the graphic element according to the parent-child logical relationship between the multiple graphic elements in the ladder diagram.

[0086] In the ladder diagram, the parent node list can be determined based on the graphics elements that have a parent-child relationship with a certain graphics element, and all the parent-relationship graphics elements of the graphics element can be determined to determine the parent node list, and all the child-relationship graphics elements of the graphics element can be determined to determine the child node list.

[0087] S304: Determine the node attributes of the graphic element according to the device information corresponding to the graphic element, where the node attributes include a root node, a terminal node, and a child node.

[0088] like Figure 2 In the ladder diagram shown, the node attributes of the graphic elements Input and Output are the root node and the terminal node respectively, and the node attributes of other graphic elements are child nodes.

[0089] The data structure includes the node name, the node data content, the parent node list, the child node list and the node attributes.

[0090] Table 1 below is a schematic diagram of the data structure. The data structure includes: node name, node data content, parent node list, child node list and node attributes.

[0091] Data Structure Node Name Node data content Parent node list Child node list Node properties

[0092] Table 1

[0093] In some optional embodiments, the data structure may further include other note-related information related to the primitive.

[0094] like Figure 4 As shown, in a method for preventing mislocking of a substation system provided in one or more optional embodiments of the present application, simplifying the data structure and determining a mislocking prevention logic expression include:

[0095] S401: Constructing a logical relationship tree with the plurality of graphic elements as nodes and the corresponding data structures as node data.

[0096] like Figure 5 The figure shows a schematic diagram of the logical relationship tree corresponding to the components of the ladder diagram. The input corresponding to the overall substation system is represented as a graphic element in the ladder diagram, and its corresponding node attribute is the root node, which is mapped to the root node in the logical relationship tree. The output corresponding to the overall substation system is also considered a graphic element and represented as a terminal node in the logical relationship tree.

[0097] S402: Simplifying the logical relationship tree according to the parent-child relationship and the sibling relationship among multiple nodes in the logical relationship tree.

[0098] S403: Determine the anti-mislocking logic expression according to the node data of the child nodes in the logic relationship tree after simplification.

[0099] In the substation system anti-error locking method, the graphic elements can be used as tree nodes, and the node relationship data corresponding to the graphic elements can be used as the node data of the tree nodes. The connection relationship between multiple tree nodes is determined based on the parent-child relationship and sibling relationship between multiple graphic elements, thereby converting the ladder diagram into a logical relationship tree. The overall input graphic element of the ladder diagram corresponds to the root node of the logical relationship tree, and the overall output graphic element corresponds to the terminal node of the logical relationship tree. The data structure can be simplified by simplifying the tree structure.

[0100] In a method for preventing mislocking of a substation system provided in one or more optional embodiments of the present application, simplifying the logical relationship tree according to the parent-child relationship and the sibling relationship between multiple nodes in the logical relationship tree includes:

[0101] Step 1: Starting from the root node, determine whether the root node has only one child node and whether the degree of the logical relationship tree including the root node and the terminal node is 3. If so, simplification ends.

[0102] Step 2: Starting from the root node, multiple tree nodes in the logical relationship tree are traversed and merged according to the depth-first search algorithm, first merging the sibling relationship nodes in the child nodes of the current tree node, and then merging the parent-child relationship nodes of the current tree node;

[0103] Step 3: After traversing all tree nodes, return to step 1.

[0104] In some optional embodiments, the merging of sibling relationship nodes can first determine the sibling node of the current tree node. If the tree node and the sibling node have the same parent node and child node, the sibling node is merged with the tree node, and the node data of the sibling node are merged according to the OR relationship during the merging.

[0105] like Figure 6 FIG. 1 is a schematic diagram of the process of merging brother nodes in the logical relationship tree.

[0106] In the exemplary logical relationship tree, node A and node B are brother nodes with the same parent node and child node. The two are merged according to an OR relationship, and the merged node is represented as "A|B".

[0107] The child node of the tree node is merged with the tree node, and during the merging, the data contents of the parent node and the child node are merged according to an AND relationship.

[0108] like Figure 7 FIG. 1 is a schematic diagram of the process of merging parent and child nodes in the logical relationship tree.

[0109] In the exemplary logical relationship tree, the C node and the E|F node are parent and child nodes, and the two are merged according to the AND relationship. The merged node is represented as "C&(E|F)".

[0110] The simplification is completed when the root node in the logical relationship tree has only one child node and the degree of the logical relationship tree including the root node and the terminal node is 3.

[0111] When simplifying the logical relationship tree, the node data contents of the brother nodes and the parent-child nodes are merged, and the logical relationship between the nodes is also simplified. Finally, the logical relationship tree can be simplified to include only one child node, which contains the node data information of all nodes.

[0112] Here, sibling nodes refer to tree nodes with the same parent node. The same parent node includes both a single parent node and multiple parent nodes. If there is a single parent node, the parent node can be the same. If there are multiple parent nodes, it is necessary to ensure that every parent node of sibling node A is in the parent node list of sibling node B, and every parent node of sibling node B is in the parent node list of sibling node A.

[0113] In a method for preventing mislocking of a substation system provided in one or more optional embodiments of the present application, merging sibling nodes in child nodes of a current tree node includes:

[0114] Determining a master node and a slave node among the sibling relationship nodes;

[0115] Merging the node data content of the slave node with the node data content of the master node;

[0116] Deleting the slave node from the child node list of the parent node of the slave node;

[0117] The slave node is deleted from the parent node list of the child nodes of the slave node.

[0118] In the method for preventing mislocking of the substation system, when merging brother relationship nodes, the node data of other related nodes are also adjusted accordingly to ensure that after the merger, the node data of each node still meets the data structure of the node relationship data. After the merger, the node data format of multiple tree nodes in the logical relationship book remains consistent, thereby avoiding affecting subsequent simplified operations.

[0119] In a method for preventing mislocking of a substation system provided in one or more optional embodiments of the present application, the merging of parent-child relationship nodes of the current tree node includes:

[0120] In the parent-child relationship node, merging the node data content of the child node with the node data content of the parent node;

[0121] Deleting the child node from the child node list of the parent node;

[0122] The child node list of the child node is merged with the child node list of the parent node.

[0123] In the method for preventing mislocking of the substation system, the node data of the child node is adjusted accordingly when the parent and child nodes are merged to ensure that after the merger, the node data of each node still meets the data structure of the node relationship data. After the merger, the node data format of multiple tree nodes in the logical relationship book remains consistent, thereby avoiding affecting subsequent simplified operations.

[0124] One or more optional embodiments of the present application provide a method for preventing mislocking of a substation system. After determining node relationship data of a plurality of elements in the ladder diagram, the method further includes:

[0125] The completeness of the ladder diagram is judged according to the node relationship data.

[0126] The determining the completeness of the ladder diagram according to the node relationship data includes:

[0127] Determine whether the graphic element with the node attribute of child node exists in the parent node list or the child node list is empty;

[0128] In response to the existence of the parent node list or the child node list being empty, it is determined that the ladder diagram is incomplete.

[0129] It can be understood that the method can be executed by any device, equipment, platform, or device cluster with computing and processing capabilities.

[0130] It should be noted that the method of one or more embodiments of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied in a distributed scenario and completed by multiple devices working together. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of one or more embodiments of the present application, and the multiple devices will interact with each other to complete the described method.

[0131] It should be noted that the above description is of specific embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims can be performed in an order different from that described in the embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order shown or the sequential order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0132] On the other hand, based on the same inventive concept as any of the above method embodiments, an embodiment of the present application also provides a substation system anti-mislocking device.

[0133] like Figure 8 As shown, one or more optional embodiments of the present application provide a substation system anti-mislocking device, including:

[0134] The device information acquisition module 801 is used to acquire device information of the substation system and create a ladder diagram based on the device information;
