Design And Research Of Indoor Precise Real-time Location System Based On UWB

With increasing global demand for data services and multimedia services,the demand for indoor and guide people is also increasing,especially in complex indoor environments such as shopping malls,airports,attractions,mines,underground car parks and other environments,often need determine the user,valuables,important infrastructure location in the room.However,limiting the building block,indoor environmental conditions,resulting in GPS and Beidou navigation and positioning system in the room is almost paralyzed because microwave signals emitted by the satellite is too weak,and very high frequency,that is,to propagate along a straight line,and difficult to pass through the wall,so it can't get a signal indoors.Based Indoor Positioning System for further research,the article synchronization algorithm from the radio clock,tag collision algorithms and scalable network protocols were carried out corresponding research,and based on the above studies were completed the design and implementation of hardware,protocol design algorithms and implementation,while the implementation of the system were carried out to test the system,positioning accuracy testing,stress testing,data backhaul testing,etc.,further evidence of the reliability and validity of the system.The success of the system can help achieve complete flow monitoring retail statistics and data analysis,and data analysis and insight through the large consumer behavior,to better provide quality services for consumers and further obtain a higher commercial value;on the one hand can improve the supplementary medical institutions,enterprises,mines,services and other operational efficiency,real-time monitoring and in-room property staff to ensure financial security and personal safety,and in the case of the efficient implementation of various emergency rescue personnel;on the other hand can assist service robots complete real-time path planning to ensure better quality of service,while in first aid,restaurant service,power line patrol and other fields to play a more important role.
