[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] The content of the present invention is described in detail below with reference to embodiments.

[0028] Reference Figure 1 The figure is a flow chart of a multi-person collaborative smart grid emergency drill method provided by an embodiment of the present invention.

[0029] In this embodiment, the method includes: S11, receiving a drill request from a first user, and presenting a plurality of emergency drill virtual scenes of a power grid emergency drill to the first user according to the drill request, wherein each of the emergency drill virtual scenes has a plurality of preset drill roles, and each drill role is configured with a corresponding drill task; S12, automatically recommending a drill scene from the plurality of emergency drill virtual scenes as a target simulation training scene according to the personalized knowledge graph of the first user, and / or using the drill scene selected by the first user as a target simulation training scene; S13, creating a virtual room based on the target simulation training scenario, and adding the first user to the virtual room; S14, determining whether a second user joins within a preset time, and if so, adding the second user to the virtual room, and determining exercise roles and exercise tasks for the first user and the second user; S15, obtaining a drill result obtained by the first user and the second user performing a multi-person collaborative interactive drill according to the drill steps of the target simulation training scenario according to the corresponding assigned drill task; S16: Update the personalized knowledge graphs corresponding to the first user and the second user according to the drill results.

[0030] Furthermore, the method further comprises: S17, if the main training device in the training room is turned on, the desktop fusion software of the secondary training device connected to the main training device is run to present the training scene, and the real-time training process of the target simulation training scene is displayed by multi-projector fusion using the desktop fusion software.

[0031] In this embodiment, the method is implemented based on the constructed power grid emergency drill system. Figure 2As shown. The power grid emergency drill system includes user terminals (APP running terminals), servers and training room terminals in different spaces. The power grid emergency drill system realizes the multi-person collaborative interactive smart grid emergency drill function through the collaborative work of the user terminal, the training room terminal (including the main training equipment and the secondary training equipment) and the server. Among them, the user terminal is used to realize the selection or personalized recommendation of drill scenes, virtual rooms and roles, including the user logging in to the APP. The server is connected to the user terminal and the training room terminal through the websocket protocol. The server is responsible for processing the data transmission and interaction instructions between the user terminal and the training room terminal. The server receives the voice interaction data and drill operation data from the user terminal and transmits them to the training room terminal for the presentation of the simulation scene. The training room includes main training equipment and secondary training equipment. The main training equipment mainly runs the drills of AI simulation training software. The secondary training equipment works together with the main training equipment to jointly build a training space. The secondary training equipment mainly runs the desktop fusion software, and displays the real-time drill process of the simulation training scene through the fusion of multiple projectors, that is, the fusion of multiple projectors on the four sides of left, middle, right and ground into the same side, so as to form a naked-eye training space on the main training room side, so that all personnel in the physical space in the training room can watch the entire training and drill process with naked eyes without wearing any hardware equipment such as 3D glasses.

[0032] Furthermore, in step S12, taking the exercise scenario selected by the first user as the target simulation training scenario includes: According to the first user selecting one of the emergency drill virtual scenes as the target simulation training scene; or One of the drill scenarios automatically recommended according to the personalized knowledge graph of the first user is selected as the target simulation training scenario.

[0033] In this embodiment, users Y1, Y2, Y3, Y4 and others only need to log in to the user terminal and run the APP to enter the power grid emergency drill system. Then, a different personalized knowledge graph recommendation module will appear for each user. Users can select one of the drill scenes from the multiple emergency drill virtual scenes presented in the interface as the target simulation training scene for drill according to their own needs or the scenarios they want to train. They can also select one of the drill scenes automatically recommended by the personalized knowledge graph as the target simulation training scene, or directly use a drill scene automatically recommended by the personalized knowledge graph as the target simulation training scene.

[0034] Reference Figure 3As shown. In this embodiment, the learning process based on the personalized knowledge graph can be achieved by adopting the CNN convolutional neural network and introducing the ResNet algorithm structure through data preprocessing (including data set preparation, data cleaning, and extraction of data features, etc.), model construction, model training, and model evaluation and optimization. The knowledge graph recommended for each user is personalized. Among them, the data set can be constructed by obtaining the user's rehearsal results, which includes the training role age, training role selection, training role interest, training role expertise, the dwell time of each rehearsal step, and the role interaction score of each rehearsal scene obtained through multiple rehearsals.

[0035] For example, Xiao Zhang is a staff member of a county-level substation monitoring center in the power grid. His main responsibilities include monitoring the operating status of power equipment, analyzing and judging the causes of equipment failures, coordinating the handling of equipment failures, maintaining and managing the monitoring system, keeping relevant records and reports, and being familiar with power equipment and monitoring systems. Xiao Zhang can send a drill request by logging into the APP in the actual job position or the actual physical space. After logging in, the system will display multiple emergency drill virtual scenes for Xiao Zhang to choose independently. For example, Xiao Zhang can not only choose the drill scenes that need to be trained for his position (such as virtual scenes such as power equipment operating status monitoring and fault analysis and judgment), but also choose the drill scenes that need to be trained for other positions (such as the role of the ground dispatching exercise dispatcher A, such as the grid dispatching coordination emergency handling, simulated transmission line fault repair, simulated substation switch cabinet flooding repair, simulated low-lying substation flood prevention, simulated hazardous chemicals enterprise power supply emergency, etc.) to understand and familiarize himself with the work of the ground dispatching exercise dispatcher A; it will also display a personalized knowledge map recommendation, which can recommend suitable drill scenes for Xiao Zhang by combining Xiao Zhang's current position and historical reference data. Furthermore, user Xiao Zhang conducts multiple drills and uses the drill results he obtains (including the age of the training role, the selection of the training role, the interests of the training role, the expertise of the training role, the dwell time of each training role in the corresponding step, and the role interaction score of each drill scenario) to build the above-mentioned personalized knowledge graph.

[0036] Furthermore, in step S13, creating a virtual room based on the target simulation training scenario and adding the first user to the virtual room includes: By detecting whether the main training device at the training room end is turned on, if so, the first user is added to the virtual room created by the main training device; otherwise, the current device of the first user is used as the training device and a virtual room is created, and the first user is added to the virtual room.

[0037] Furthermore, in step S14, adding the second user to the virtual room and determining the exercise roles and exercise tasks for the first user and the second user include: receiving a first role selected by the first user, assigning a corresponding exercise task to the first role, and obtaining remaining exercise tasks; The second role selected by the second user is received, and corresponding training tasks are assigned to the first role from the remaining training tasks.

[0038] Furthermore, in step S14, adding the second user to the virtual room and determining the exercise roles and exercise tasks for the first user and the second user include: The second user is added to the virtual room and the second role selected by the second user is received. After the corresponding exercise tasks are assigned to the second role, the remaining unassigned exercise tasks are assigned to the first user.

[0039] Further, in step S14, the determining whether a second user joins within a preset time includes: If no second user joins within the preset time, all the practice tasks corresponding to the target simulation training scenario are assigned to the first user, and the first user performs the practice according to the practice steps of the target simulation training scenario.

[0040] In this embodiment, when user Y1 selects a certain drill scene (such as simulating the repair of a power transmission line fault), the system will detect whether the virtual room of the main training device at the training room end is open. If it is open, user Y1 will join the virtual room that has been created and set, and start the multi-person training drill according to the currently selected role within the preset time (such as 10 seconds). If the virtual room of the main training device is not open, then user Y1 will automatically create a virtual room and wait for the second user to join as the main training device. If a second user Y2 joins within the preset time (such as 10 seconds), a multi-person collaborative drill will be carried out. User Y2 selects a certain role J1 and assigns the corresponding drill task (such as including 6 interactive drill steps). The remaining X (such as including 25) interactive steps are all executed by Y1; if no second user Y2 joins within the preset time (such as 10 seconds), then all interactive steps (31 interactive steps) are executed by user Y1 himself.

[0041] Reference Figure 4As shown. The specific allocation situations include: in the first situation, user Y1 joins the virtual room mode of the main training equipment (the virtual room of the main training equipment is turned on at this time), user Y1 can only practice the drill steps corresponding to the role he chooses, such as choosing role J1 to practice the corresponding 6 steps; in the second situation, user Y1 builds the virtual room R1 by himself, and no other user joins the virtual room R1 created by himself within 10 seconds, user Y1 needs to perform the entire 31 interactive steps of the virtual drill scene of simulating the emergency repair of a power transmission line fault in a certain place; in the third situation, user Y1 builds the virtual room R1 by himself, user Y2 joins and chooses role J2, user Y2 needs to complete the 7 steps corresponding to the role J2, and the remaining 24 steps (31-7=24) are all completed by user Y1; In the fourth case, user Y1 builds virtual room R1, user Y2 joins and selects role J2. User Y2 needs to complete the 7 steps assigned to role J2. User Y3 joins and selects role J3. User Y3 needs to complete the 3 steps assigned to role J3. The remaining 21 steps (31-7-3=21) are all completed by user Y1. There are many cases later. The role selection adopts the priority selection in the order within 10 seconds. The same exercise scene has been selected by default and cannot be selected again until the step corresponding to the last role is given to Y1 who created the virtual room. The steps X required for Y1 to interact = (31-the sum of the exercise steps of the selected role). This multi-person collaborative role allocation principle is conducive to the formation of multi-person collaborative interactive exercises for two, three, four, and five people. For users who are conducting exercises, they can independently select the simulation scene that corresponds to the current position or the position they expect to engage in. It is both real and has a strong autonomous allocation principle, so that the multi-person interactive exercises learned are more in line with the needs of real work scenarios.

[0042] The above simulation exercise scenario involves 31 interactive steps, which are executed by different roles at different times and in a certain order. The roles in the simulation exercise scenario include a provincial surveyor, a municipal surveyor A, a municipal surveyor B, a county surveyor, a dispatch director, and a substation monitoring team member. For example, when user Y2 joins the virtual room created by user Y1, the two conduct practical training in the simulation exercise scenario within 10 seconds and select a role J1 (a surveyor A). Then the drill steps that role J1 needs to interact with are: step 2 to notify a county operation and maintenance team to go to the site, step 3 to notify the transmission operation and inspection center, step 5 to discuss during the shift, and step 6 to report to a provincial dispatcher (a surveyor is the abbreviation of a regional dispatcher; a provincial dispatcher is the abbreviation of a provincial power dispatching center).

[0043] Further, in step S15, the acquisition of the drill result obtained by the first user and the second user performing the multi-person collaborative interactive drill according to the drill steps of the target simulation training scenario according to the corresponding assigned drill task includes: During the rehearsal process, the voice interaction data, rehearsal operation data and rehearsal progress of the first user and the second user are collected in real time to obtain the rehearsal results including the completion status of each rehearsal step, the role interaction score and the stay time.

[0044] In this embodiment, the drills that different users can conduct through the user end (such as the mobile phone APP end) are mainly telephone voice communications. The interactive mode of the power grid emergency drill system mainly adopts real-time speech recognition technology, combined with the algorithms of models such as CNN and LSTM to more accurately output the two-way transmission of user input voice, especially for some county-level personnel with local dialects, which can better recognize related voices and realize human-computer interaction. That is, different users mainly interact with each other by voice, and the user ends in different spaces transmit the recognized voice interaction data to the server through the websocket protocol, while the training room end obtains the interactive instructions of the training drill scene through the websocket protocol, and simulates the process of daily emergency drills through the implementation of these instructions.
