Description

Technical Field

[0001] The present invention relates to the field of computer science and technology, and in particular to a hybrid office efficiency optimization system based on digital twins and spatial computing. Background Art

[0002] With the rapid development of information technology and the profound transformation of office models, hybrid office models, with their advantages of combining flexibility and collaboration, have become a mainstream trend in modern corporate offices. In this model, the integration of physical office spaces and remote working scenarios places higher demands on optimizing office efficiency. Digital twin technology, by constructing a virtual mapping of physical space, can mirror the relationships between people, objects, and space in an office environment in real time. Spatial computing provides key technical support for processing complex three-dimensional scene data and optimizing spatial resource allocation. In this context, how to leverage digital twin and spatial computing technologies to dynamically model and intelligently optimize elements such as workstation layout, equipment scheduling, and personnel collaboration in hybrid office scenarios has become an important research direction for improving office efficiency and reducing operating costs.

[0003] However, current efficiency optimization solutions for hybrid office environments still leave much to be desired. On the one hand, traditional office space management systems often limit their data collection of the physical environment to a single dimension, such as focusing solely on workstation usage or equipment energy consumption. They lack the integrated perception and in-depth analysis of multiple sources of data, including personnel movement trajectories, environmental parameters, and collaboration needs. This results in an inaccurate and comprehensive digital mapping of the office scene. On the other hand, existing optimization models often rely on static layout planning and fixed policy configurations, making them difficult to adapt to the dynamic scenarios of hybrid offices, characterized by high personnel mobility and changing task demands. They also have significant shortcomings in balancing multi-objective optimization objectives such as space utilization, equipment energy efficiency, and personnel collaboration efficiency, and lack mechanisms for coordinating optimization between remote collaboration tools and physical office resources. Furthermore, some systems oversimplify the calculation of key parameters such as spatial topology and accessibility metrics during data processing and model construction, ignoring practical constraints such as obstacle occlusion and path attenuation. This limits the feasibility and effectiveness of optimization solutions. To address this issue, we propose a hybrid office efficiency optimization system based on digital twins and spatial computing.

[0062] Figure 2 It is a system workflow diagram of the present invention. DETAILED DESCRIPTION

[0063] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0064] Reference Figure 1 As shown in the figure, the hybrid office efficiency optimization system based on digital twin and spatial computing includes:

[0065] The data acquisition module is the foundation of the entire system, acting as its "senses," capturing key information about the physical office space in real time. An IoT sensor array, comprised of positioning base stations, thermal imagers, smart meters, and acoustic sensors, is deployed here. The workstation status perception submodule utilizes a pressure sensor array to accurately collect workstation contact time data and, by calculating workstation utilization rates per unit time, provides real-time insights into each workstation's usage. The environmental parameter acquisition submodule utilizes a distributed sensor network to construct three-dimensional thermal maps incorporating information such as temperature, humidity, and gas concentration, providing detailed data support for understanding office comfort and air quality. The personnel trajectory tracking submodule, utilizing a positioning system comprised of positioning tags and base stations, accurately calculates the deviation between a person's actual movement path and a theoretical straight-line path, providing a clear understanding of their movements within the office space. To ensure data quality, the data preprocessing unit uses filtering algorithms to remove noise from the raw data and constructs a time series database containing timestamps, spatial coordinates, and motion vectors, providing a clean and organized data foundation for subsequent analysis and processing.

[0066] The 3D modeling module, serving as one of the system's "brains," builds a virtual twin based on a spatial computing engine, mirroring the physical space. It utilizes voxelized reconstruction technology to convert point cloud data into a regular grid model. It automatically adjusts spatial resolution based on site dimensions using dynamic thresholds, ensuring both accurate and efficient models. A dynamic update mechanism triggers model reconstruction by calculating the rate of change in the model volume over time, enabling the virtual model to reflect changes in the physical space in real time. For workstation unit modeling, parametric templates are used to define dimensions, interface types, and viewing angles, ensuring each workstation has a precise digital representation in virtual space. Personnel avatars map their real-world postures using skeletal joint coordinates, making human movement in virtual space more realistic and believable. Furthermore, the spatial topology analysis submodule calculates distance-attenuated accessibility metrics between workstations, providing crucial spatial relationship data for subsequent simulation analysis and configuration optimization.

[0067] The simulation and analysis module applies a multi-objective optimization algorithm to establish a space-time constraint model, aiming to find the optimal solution for office space utilization through scientific calculation and analysis. This module uses a multi-objective genetic algorithm framework to define a set of decision variables, including a workstation layout matrix, a set of meeting time intervals, and a remote tool weight vector. These variables cover the key factors in office space management. Constraints include a lower limit on workstation spacing, equipment service radius limits, and collaboration path length thresholds to ensure the feasibility of the optimization solution in practical applications. The objective function is set as a weighted indicator that comprehensively optimizes space utilization, energy efficiency, and time efficiency. Space utilization is measured by the proportion of used area, energy efficiency is calculated by the sum of the products of equipment operating power and usage time, and time efficiency is evaluated by a linear combination of waiting time, communication delay, and meeting preparation time, comprehensively considering all aspects of office efficiency.

[0068] The optimization configuration module generates the optimal solution set based on the iterative genetic algorithm, which is a key link in achieving precise optimization of the system. In the initialization phase, the appropriate population size and maximum number of iterations are set, and a hybrid encoding method is used to perform chromosome encoding on the workstation layout, meeting time and tool combination, converting the actual problem into a form that the algorithm can handle. The fitness function balances the various optimization objectives through dynamic weight coefficients to ensure that the algorithm does not favor a certain goal and ignore other goals during the optimization process. The selection operator adopts a competitive screening strategy to retain excellent individuals and eliminate poor individuals to improve the overall quality of the population. The crossover operation implements the block exchange of the workstation layout matrix and the reorganization of the meeting time interval. The mutation operation includes the replacement of workstation positions, the offset of time windows and the random adjustment of tool weights. These operations increase the diversity of the population, prevent the algorithm from falling into the local optimum, and thus find a better solution.

[0069] The configuration output module serves as a bridge between the system and actual applications. It generates an executable strategy package containing the optimal space layout plan, equipment configuration list, and schedule planning table, and outputs control instructions through the building management system interface to effectively apply the optimization plan to the actual office environment. This module includes a space utilization optimization submodule and a space overlap detection submodule. The space utilization optimization submodule implements a multi-level optimization strategy. At the macro level, it divides functional areas through geometric shapes and calculates the compactness of regional morphology to make the functional zoning of office space more reasonable; at the meso level, it uses mechanical models to adjust the layout spacing of workstations, improving space utilization while ensuring employee comfort; at the micro level, it optimizes the orientation angle of workstations through visibility scoring to enhance the employee work experience. The space overlap detection submodule uses the bounding box projection method to identify layout conflicts, ensuring that there are no physical conflicts in the optimized space layout, ensuring the feasibility and safety of the plan.

[0070] In summary, the hybrid office efficiency optimization system based on digital twins and spatial computing achieves intelligent management and optimization of office space through the collaborative work of various modules. From data acquisition to 3D modeling, from simulation analysis to optimized configuration, and finally to configuration output, each link is closely interconnected and interconnected, providing strong technical support for improving hybrid office efficiency.
