[0042] like Figure 1 As shown, the present invention provides a unified coding method for collecting park equipment assets using the Internet of Things, including:

[0043] S100, uniformly encode equipment assets;

[0044] The unified coding of building and park equipment assets, including intelligent IoT equipment and non-intelligent IoT assets, including but not limited to the dedicated ID coding of equipment assets, becomes the basis of IoT construction and forms data assets; intelligent equipment assets and non-intelligent equipment assets form a unified coding format, fully apply IoT technology to realize intelligent asset inventory, and accurately and comprehensively realize asset inventory management; as an important application of building digital twins, realize the positioning, display, interaction, information attribute definition and other applications of equipment and assets in digital space; the unified equipment asset coding method goal makes the intelligent collection application scope of IoT equipment assets expand from single buildings to building complexes, and from building complexes to building parks, and the data collection scope of IoT can cover multiple regions and multiple parks. The unified management and automated inventory of intelligent equipment and non-intelligent equipment assets are realized through IoT technology. Intelligent devices can collect information and transmit data, while non-intelligent devices can be included in the unified management system through additional identification. This combination improves asset management efficiency, reduces the need for manual intervention, and can monitor equipment status in real time and update information on the asset management platform in a timely manner.

[0045] S200, build a 3D model of the corresponding building based on digital twin technology;

[0046] Create a 3D model of a campus or building, and use digital twin technology to display the layout of the entire environment and the distribution of equipment. Provide an intuitive visual experience so that managers can quickly understand the location and status of equipment. At the same time, based on the unified coding characteristics of spatial information, the equipment is associated with the space, and the spatial relationship between equipment is also generated. Build a 3D model and align it in space, providing an intuitive visual experience so that managers can quickly understand the location and status of equipment, facilitating management and decision-making.

[0047] S300, optimizing spatial data processing in the video surveillance system using a spatial optimization search algorithm;

[0048] By dividing the monitoring area into multiple grids and assigning a code to each grid, refined management of the monitoring area is achieved. The heuristic algorithm is used to automatically select the optimal monitoring angle and area to ensure that key areas are fully covered. In addition, the monitoring range of the camera is dynamically adjusted according to actual needs to improve monitoring efficiency and resource utilization.

[0049] S400, ensuring accurate spatial alignment of the video surveillance image with the 3D building model;

[0050] By extracting key feature points from the video image and matching them with corresponding points in the 3D building model, the geometric transformation matrix is ​​calculated and the position of the video image is adjusted to perfectly align it with the 3D model. This process also requires adjusting the camera parameters and model coordinate system to ensure that the video image and the 3D model are completely consistent in space, providing an accurate monitoring perspective.

[0051] S500, integrating the real-time video data with the state information of the building model to achieve accurate mapping of the target or event in the video in the three-dimensional model;

[0052] Realize the integration of video data and building model status information, ensure data consistency and integrity, and improve data utilization efficiency.

[0053] S600, detects data through intelligent analysis technology;

[0054] Automatically detect abnormal behaviors and trigger alarm mechanisms to promptly identify and address potential safety hazards and improve the safety management level of the park.

[0055] S700: Provide visual feedback on the processing results.

[0056] The system displays the results of system processing to users in the form of charts, maps, animations, etc., supports multi-terminal access, and provides a friendly user interface. Users can quickly obtain key information through these visualization tools to assist in decision making and execution.

[0057] In one embodiment, if Figure 2 As shown, the unified coding of equipment assets includes the following steps:

[0058] S101. Define the coding principles for equipment assets;

[0059] S102, adding spatial level coding information to the coding;

[0060] The coded information at the spatial level includes but is not limited to analyzing the characteristics of building space, defining the spatial hierarchy and integrating geographic information systems. The purpose of analyzing the characteristics of building space is to understand the spatial layout of the building, including functional divisions such as floors, rooms, and areas. This can be achieved by collecting relevant information such as architectural design drawings and construction documents and using BIM models to assist in analysis. The purpose of defining the spatial hierarchy is to define the spatial hierarchy. The spatial levels can be divided from large to small, such as countries, cities, parks, buildings, floors, rooms / areas, and equipment point arrangements. Each level can be represented by short letters or numbers. The purpose of integrating geographic information systems is to combine spatial coding with geographic location information to provide more accurate positioning services. This can be achieved by introducing GIS technology to give each spatial unit specific latitude and longitude coordinates, so that the location of the equipment can be accurately displayed on the map.

[0061] S103. Subdivide and classify the coding attributes.

[0062] Adding space-level coding information to the equipment asset coding facilitates the management and positioning of equipment. Through a unified coding system, unique identification and standardized management of equipment assets are achieved, thereby improving the efficiency and accuracy of equipment management.

[0063] In one embodiment, the coding principles include uniqueness, stability, bit limit, operability and scalability of the coding.

[0064] Coding should ensure that each type of information element has a unique identifier, which is mainly used for data storage and retrieval. If the code is not unique, the smart park will not be able to summarize the data of its entire life cycle; the code should be relatively stable and should not change for a period of time. It is advisable to select the most stable essential attributes or characteristics of the coding object as the basis and basis for classification; the number of coding digits should take into account the category and quantity. In order to facilitate the management of all codes, the number of coding digits should be considered as comprehensively as possible and minimized; the coding should be easy to understand, identify, browse and query to meet the actual needs of the smart park; considering future development, leave room for adding new coding objects to facilitate coding maintenance. One is the expansion of categories, and the other is logarithms; the usual practice is to set up containment categories to ensure that when new things are added, the established classification and coding system is not disrupted, and at the same time, conditions should be created for extension and refinement under this system. The coding attributes of the subdivided classification include feature code attribute coding, system category attribute coding, organization coding, equipment coding definition and extended attribute coding.

[0065] In one embodiment, if Figure 3 As shown, using the spatial optimization search algorithm to optimize the spatial data processing in the video surveillance system includes the following steps:

[0066] S301, dividing the monitoring area into multiple grids, and assigning a code to each grid;

[0067] S302, finding the most suitable monitoring angle or area through a heuristic algorithm;

[0068] S303: Dynamically adjust the monitoring range of cameras and other equipment within the monitoring area according to actual needs.

[0069] In one embodiment, if Figure 4 As shown, ensuring accurate spatial alignment of the video surveillance image with the 3D building model includes the following steps:

[0070] S401, extracting key feature points from the video image and matching them with feature points in the three-dimensional building model;

[0071] S402, calculating a geometric transformation matrix according to the matching result, and adjusting the video image to a position aligned with the building model;

[0072] S403: Adjust the camera parameters and the model coordinate system to ensure that the video image and the three-dimensional model are completely aligned in space.

[0073] In one embodiment, if Figure 5 As shown, detecting data through intelligent analysis technology includes the following steps:

[0074] S601, using a pre-trained deep learning model to detect targets in the video;

[0075] S602: Track the motion trajectory of the target in the video screen using corresponding algorithms according to different targets, and provide continuous monitoring information and calibration of abnormal behavior;

[0076] S603: When abnormal behavior is detected, an alarm mechanism is triggered.
