Research On Vehicle Location System Based On Wireless Sensor Technology

The rapid development of intelligent public transportation system has positive significance for solving traffic problems and environmental problems.It is one of the main contents in the development of major cities.The development of intelligent public transportation system depends on the vehicle location base.GPS as the core of vehicle location technology plays an important role in the development of intelligent public transportation,and has been applied in all directions.But from the current actual situation of the vehicle positioning technology,using GPS technology,high cost,may be due to various factors lead to signal interruption and other related problems in the application,so how to solve these problems has become one of the problems to be solved in the development of intelligent transportation system.Based on the analysis and Study on bus,vehicle positioning system carries on the comprehensive analysis and research: first,analysis of the routing protocol for wireless sensor networks,and combined with the characteristics of intelligent vehicle positioning system,the routing protocol of bus location system based on wireless sensor network is designed;secondly,the wireless sensor network node automatically an algorithm is discussed and analyzed comprehensively,combined with the needs and characteristics of bus location service,and puts forward the positioning algorithm;finally,based on nRF905 RF transceiver chip,ATmega16 L as wireless sensor bus location system based on microprocessor,the full realization of the design and development of hardware and software.Compared with the traditional GPS positioning system,wireless sensor network positioning technology has the main advantages and features of low operating cost and simple system maintenance.It has a broad market in the future positioning field.The wireless sensor network positioning technology in the process of design and development of vehicle positioning system in this thesis,combined with the technology of routing protocol and localization algorithm related to the system,conducted a comprehensive analysis,through the analysis and research to the future development of intelligent public transportation system play a certain significance.
