Bus Management And Positioning System Of Internet Of Things Based On ZigBee

With the development of urban traffic congestion,public transportation is an important way to ease urban traffic pressure and realize the sustainable development of road traffic.This paper designs and realizes the bus management system based on ZigBee,realizes the real-time monitoring of the bus and the remote control,as well as the positioning function on bus station,and improves the efficiency of the bus operation and reduces the unnecessary waste of resources.This paper studies the development course and the research status of the domestic and foreign intelligent public transportation system.The basic principle and characteristics of the wireless sensor network,802.15.4 IEEE protocol and ZigBee protocol are studied.The feasibility of the integration of the Internet of things based on ZigBee is analyzed.Based on the analysis of the RSSI based wireless location technology,this paper presents a fingerprint positioning algorithm for engineering application.The algorithm optimizes the data processing of the fingerprint database,reduces the amount of data in the database,optimizes the sampling data,and adds the weighting factor based on the K correlation,and improves the computing efficiency and the location accuracy of the positioning algorithm.Finally,the paper focuses on the design and implementation of bus positioning and management system,introduced the ZigBee network in three parts:vehicle terminal,roadside equipment and roadside equipment routing convergence hardware module design and the software process,then introduces the design and Realization of some specific software function and system optimization function.The test shows that the system runs stably and smoothly,and can realize the business process of the system,and have a reliable positioning accuracy,fully meet the application needs of the project.
