Design And Implementation Of Smart Building Location Management Subsystem Based On Real-time Indoor Positioning

With the rapid development of information technology,smart buildings have been increasingly mentioned and become a direction strongly supported by governments and a significant application scene for software and hardware services.Traditional smart building systems or solutions focused on using various sensors to collect building data,analyzing the results and visualizing the display to assist personnel management and decision-making.Alternatively,based on video real-time monitoring of rooms or assets,they used video processing algorithms to achieve intelligent building security and reduce manpower input.Or based on building energy consumption data,they designed intelligent adjustment algorithms to reduce energy consumption without causing inconvenience to personnel.These smart buildings achieved good results in the above areas,but lacked effective ways to obtain real-time location information of personnel inside the building and have not fully utilized the value of personnel location information,missing the opportunity to provide more intelligent services.Based on the above background,this paper designed and implemented a smart building positioning management subsystem based on real-time indoor personnel location data for building management personnel.Following the software engineering development process,this paper first analyzed the background and research status of the project and introduced the technologies required for the system,such as Unity3D and Spring Boot.Then,this paper took the school research building as the target scenario and conducted a comprehensive analysis of the system requirements using use cases and other forms.Based on the results of the requirement analysis,this paper performed a high-level design of the system,including the layered design of the system architecture.Subsequently,in the functional module diagram,this paper designed six major modules and their sub-modules for this system:user module,personnel location module,electronic fence module,personnel attendance module,personnel trespass module,and patrol module.The logical structure of the database was analyzed using an E-R diagram,and the table structure design was completed.Furthermore,based on the high-level design,this paper conducted detailed design and implementation of each functional module using class diagrams and sequence diagrams.Finally,appropriate test cases were written to test the system’s functional and nonfunctional requirements,ensuring that the system operated correctly,reliably,and securely.In addition,for the patrol module,this paper experimentally compared multiple route planning algorithms and conducted real tests in a 7-floor research building model with a realistic scale.The results were evaluated from the perspectives of execution efficiency and route length,and the suitable implementation solution for the scenario was determined.Ultimately,by combining indoor positioning,this paper supervised and recorded the patrol tasks,standardizing the patrol process and ensuring task quality.This paper completed the development and testing of the positioning management subsystem,providing a comprehensive application service for building location management.The system ultimately extended the capabilities and boundaries of building management personnel,bringing higher efficiency and more convenience to building management work,and had great social application value.
