[0045] The principles and characteristics of the application are described below in combination with the drawings, and the embodiments are only used to explain the application, and are not used to limit the scope of the application.

[0046] As Figure 1 shown, a flowchart is provided for an embodiment of the model automatic mapping method of the application, and the model automatic mapping method comprises:

[0047] obtain a model file, a scene file and a twin data file for a newly created scene;

[0048] It should be noted that the model file contains a model for creating a scene. Taking a building as an example, the model can be a wall, a pipeline, a texture map, etc. Figure 2 As shown in the example of uploading a model file, the model file can be pre-written and then uploaded to the system to create a scene.

[0049] The twin data file contains twin data, for example, as shown in Figure 4 Taking a rack device in a certain park scene as an example, the twin data can include various models of access switches, etc.

[0050] Save the model file to the model table in the database, save the twin in the scene file and the twin in the twin data file to the twin table in the database, and the model table stores a model field and the twin table stores a device model field;

[0051] Obtain all device models from the twin table and save them as a device model array, and obtain all models from the model table and save them as a model array;

[0052] Initialize the model mapping table and save it as a model mapping array;

[0053] It should be understood that the model mapping table is pre-established, and the model mapping array stores the correspondence between the model and the device model.

[0054] For example, a certain type of cabinet can have a corresponding model of a cuboid.

[0055] According to the device model array, query each device model in the model mapping table, determine whether the current device model exists in the model mapping according to the query result, when the model mapping exists, determine whether the ID field of the device model in the model mapping table and the model ID field in the model table are consistent, modify the ID field of the device model in the model mapping array according to the determination result, and delete the current device model from the device model array, continue to query the next device model, until the device model array is empty.

[0056] It should be understood that if the device model in the device model array exists in the model mapping table, it means that the device model has been mapped to the model, and if the queried device model does not exist in the model mapping table, it means that the device model has not been mapped to the model.

[0057] When the model mapping does not exist, the device name of the current device model is matched with the names of all models in the model array, a model mapping record is added in the model mapping array according to the matching result, the current device model is deleted from the device model array, and the next device model is continuously queried until the device model array is empty;

[0058] When the device model array is empty, the data in the model mapping array is updated to the model mapping table, the model automatic mapping time is recorded, and the last modification time field in the twin table is updated.

[0059] It should be understood that the model automatic mapping will be performed immediately after the upload scene is saved successfully; after the twin data is added or modified, the model automatic mapping will be performed after the timing task, for example, the timing task is performed once every 5 seconds, and the timing task performs the model automatic mapping on the added or modified twin data by comparing the last modification time field.

[0060] In the embodiment, the device model array and the model array are established, the device models are queried in the model mapping table, and corresponding processing is performed according to the query result, the model mapping table is automatically updated after the model mapping is completed, the model automatic mapping is performed on the added or modified twin data at a timing, and the twin can be seen in the scene after the model automatic mapping is completed, so that the scene updating speed is fast, and the added twin can be displayed in time.

[0061] Optionally, in some possible implementation manners, after all the device models are obtained from the twin table, the following further includes:

[0062] The repeated device models are filtered out.

[0063] By filtering out the repeated device models, subsequent judgment and processing on the repeated device models can be avoided, so that the processing speed is provided.

[0064] Optionally, in some possible implementation manners, before the model mapping table is initialized and saved as the model mapping array, the following further includes:

[0065] It is judged whether the device model array is empty and whether the model array is empty, when the device model array and the model array are not empty, the model mapping table is initialized and saved as the model mapping array, otherwise the process is stopped.

[0066] By judging whether the device model array and the model array are empty, program errors can be avoided.

[0067] Optionally, in some possible implementation manners, when the model mapping exists, it is judged whether the ID field of the device model in the model mapping table is consistent with the model ID field in the model table, the ID field of the device model in the model mapping array is modified according to the judgment result, the current device model is deleted from the device model array, the next device model is continuously queried until the device model array is empty, and the specific operations include the following:

[0068] When the model mapping exists, it is judged whether the ID field of the device model in the model mapping table is consistent with the model ID field in the model table, when the ID field is consistent with the model ID field, the current device model is deleted from the device model array, the next device model is continuously queried until the device model array is empty;

[0069] When the ID field is not consistent with the model ID field, the ID of the device model in the model mapping array is modified to the model ID in the model table, the current device model is deleted from the device model array, the next device model is continuously queried until the device model array is empty.

[0070] By modifying the ID field of the device model in the model mapping array, the mapping relationship between the device model and the model can be automatically established, so that the system can automatically perform model mapping.

[0071] Optionally, in some possible implementation manners, when the model mapping does not exist, the device name of the current device model is matched with the names of all models in the model array according to the matching result, a model mapping record is added in the model mapping array, the current device model is deleted from the device model array, the next device model is continuously queried until the device model array is empty, and the specific operations include the following:

[0072] When the model mapping does not exist, the device name of the current device model is matched with the names of all models in the model array, when the corresponding model name is not matched, the first model name in the model array and the device name of the current device model are regarded as matching success;

[0073] When the corresponding model name is matched, the device name of the current device model and the corresponding model name are matched successfully;

[0074] The matching successful model mapping record is added in the model mapping array, the current device model is deleted from the device model array, the next device model is continuously queried until the device model array is empty.

[0075] For example, assuming that a certain model device needs an A model for display, the model array includes a B model, a C model and a D model in sequence, and the A model does not exist, the B model can be specified as the matching model of the device.

[0076] By matching the device name of the current device model with all model names in the model array, each newly added twin can be matched to the corresponding model, thereby realizing automatic scene updating, and when no corresponding model is matched, automatically selecting a model can enable each twin to be matched to the corresponding model, thereby facilitating later maintenance, and only the corresponding model needs to be added, thereby improving the usability of the scene.

[0083] When no model mapping exists, the device name of the current device model is matched with the names of all models in the model array, a model mapping record is added in the model mapping array according to the matching result, the current device model is deleted from the device model array, the next device model is continued to be queried, and the device model array is empty until the device model array is empty.

[0084] A data update unit is configured to update the data in the model mapping array to the model mapping table when the device model array is empty, record the model automatic mapping time, and update the last modification time field in the twin table.

[0085] The embodiment can automatically update the model mapping table after the model mapping is completed, so as to automatically map the model of the newly added or modified twin body data at regular time, and the twin body can be seen in the scene after the model automatic mapping is completed, so that the scene updating speed is fast, and the newly added twin body can be displayed in time.

[0086] Optionally, in some possible implementation manners, the first array generating unit is further configured to check the all device models for duplication, and filter out the duplicated device models.

[0089] When the ID field is inconsistent, the ID of the device model in the model mapping array is modified to the model ID in the model table, the current device model is deleted from the device model array, the next device model is continued to be queried, and the device model array is empty.
