A Design Of The Simulation Of Indoor Occupant Distribution System For New Style Management Platform For Intelligent Building

At present,most large-scale public buildings in China still adopt a centralized system architecture,which cannot truly achieve “automatic control” and cannot meet the requirements of industrialization development of new buildings of green buildings.To this end,the National Key R&D Program of China has developed a new set of adaptable a new style management platform for intelligent building with flat and non-central characteristics for the intelligent needs of large public buildings.In the new style management platform for intelligent building,the number of occupant in each area of the building is an important spatial attribute,which is an important decision variable for building intelligent related applications.In order to promote the research on resource intelligent control in the building area based on indoor occupant distribution in the new style management platform for intelligent building,this thesis designs a scalable and adaptive indoor occupant distribution simulation system for the new style management platform for intelligent building.The main work and results are reflected in three aspects.Firstly,the rules of indoor occupant distribution and migration are explored.The purpose is to simulate the number of occupant in each area at any given time according to the spatial distribution information of the initial time occupant,and to provide dynamic and relatively accurate indoor occupant distribution information for the simulation system.In this thesis,under the assumption that the indoor occupant migration conforms to the Markov chain model,the basic concepts of indoor occupant distribution and migration are defined.The Markov chain is constructed to model the indoor occupant migration process,and the state transition matrix is used by statistical method.The solution is solved,and finally the above model is verified by a simple example.The results show that the model can reflect the randomness and time correlation of system state transition,and can predict the trend of system state transition well.It can be used to describe and simulate the occupant migration process.Secondly,aiming at the data sharing problem in the simulation process of indoor occupant counting device,the model is modeled by the reader and writer problem,and the scheduling mechanism based on the lock mechanism is designed to make the simulation system run correctly and stably.This thesis briefly introduces the working principle of the occupant counting device,and then designs the simulation architecture of the occupant counting device according to the structure and working principle of the device,and elaborates the data sharing problem existing in the simulation process of the occupant counting device,aiming at the data between different modules.Sharing phenomenon,different scheduling strategies are designed based on readers' problems.Finally,the output of the simulation system for the number of occupant in each area is tested,and the time of simulation is counted.The experimental results show that the simulation system can operate correctly and stably which is based on the designed sharing strategy.Finally,this thesis is supported by distributed simulation and multi-threading technology.Based on the design idea of multi-agent system,this thesis designs and implements a scalable and adaptive indoor staff distribution simulation system for new style management platform for intelligent building.The simulation system supports semi-physical simulation and pure software simulation,which can simulate the distribution of occupant in the building space,give the simulation results of the occupant distribution with confidence,and report the simulation results to the new style management platform for intelligent building.The simulation system can not only adapt to the new style management platform for intelligent building of any scale,but also provide a simulation environment for the internal calibration algorithm design and verification of the indoor occupant counting device,verify the feasibility and efficiency of the calibration algorithm in the system and Potential problems are explored and researched to provide guidance for the development of indoor occupant distribution devices for new style management platform for intelligent buildings,ensuring possible errors in the system before hardware system implementation and avoiding irreparable damage during hardware development.
