Based On The GPS And Accelerometer Sports Smart Terminal Application Design And Implementation

With the further development of broadband wireless mobile communication technology and the Web application innovation, the business development of mobile internet will become another driving force in development of the Internet following the broadband technology to provide a new platform for the Internet, making the Internet more popular, along with the inherent advantages of portable, multi-functional integration, personal customization and provide new space for development and sustainable development, new business models for the Internet class business.The same time, the development of mobile Internet services for mobile network endless space, social, sports and fitness, navigation category has gradually become the main direction of the mobile Internet business.This thesis focus on sports and fitness, design and implement a sports-based intelligent teminal application.Firstly, this thesis describes the user real-life movement’s demand for elaboration, extensively investigates and analysises available in the market movement class hardware and software, organizes into several major categories, and picks out on behalf of products of the trial, the purpose is to discove its strengths and weaknesses, advantages as a learning direction of this thesis, less as the focus. The main work is divided into two directions, distance statistics and the user pace identification:through the mobile phone GPS module for the user’s real-time latitude and longitude information, with the distance formula to calculate the user’s movement away from the Earth’s sphere between two points, at the same time, using the Lander rule metadata in the multi-path effects in the calculation process of error analysis and correction; programming acceleration sensor module from the phone to get the user’s real-time acceleration data to determine the current state of motion by analyzing the characteristics of continuous change, the pace of the user’s behavior to identify. In the actual test, the two algorithms to provide reliable and accurate service, also played a role in guiding, at the same time, improve the user experience of other similar applications.In addition, the completion of the core functionality of the pedometer software, this thesis also completed the design and implementation of the corresponding auxiliary functions, including user interface design, sports historical data record query and application software power consumption control.
