Design Of Grading Intelligent Software System For Bluetooth Based On Android

In the process of preparation for athletics competitions, the host and the judgeschoose what kinds of scoring tools and how to create an atmosphere that isconducive to interact, which are issues considered by organizers. From thisperspective, combined with the advantages of the Android system and wirelesscommunication, this paper implements grading intelligent software system forBluetooth based on Android. It not only meets the need of grading, but also forms theatmosphere of interactive real-time effect.Grading intelligent software system for Bluetooth based on Android is dividedinto two parts of grading software and live software. On the basic of one-to-onecommunication mechanism for Bluetooth based on Android, this paper proposes anscheme of one-to-many communication. First of all, the scheme uses a thread poolunder Android system to achieve socket of multiple Bluetooth devices, which savesto the local cache in an collection and traverse the collection when it need anone-to-many communication, and then completes one-to-many communication forBluetooth based on Android by means of a thread pool and completes the function ofgrading. The scheme has been applied in grading software for the use of the host andthe judges. In addition, grading software also joined the design of small Sqlitedatabase to store and managed data information during the competitions. The gradingsoftware is good mobility and small volume and fast transfer speed and feature-rich,extensibility, simple operation, visual interface and good mobility. Live software isanother application for the use of the audience. it uses streaming media transmissionscheme and achieve audio and video signals from the network camera andtransplants VLC decoding library on Android to complete decode of streaming media.In addition, the live software also includes live function, switching live scene, pauseand resume play, screenshots, playing a local file, video recording function, which is a good real-time, good fluency, quickly connection.This paper has a functional test and performance about grading intelligentsoftware system for Bluetooth based on Android, which solves the problems in theprocess of test and improves the stability of the system. Finally, grading intelligentsoftware system for Bluetooth based on Android realizes the result which meets theexpectations for design and achieves to the requirements of the use of the athleticscompetitions and provides a certain theoretical significance and reference value forapplication extension for Bluetooth communication in Android platform.
