Design Of Signal Receiving And Dispatching System Based On Android Bluetooth

With the rapid development of mobile Internet.Smart phone market competition is very intense.Its related areas of competition has been reflected in the automotive industry.Traditional vehicle information service system has the advantages of large maintenance cost,weak expansion and long update period.It can not fully meet the needs of users.Car network as the future direction of development of the car.There are many car companies to increase investment in related research."Intelligent terminal + vehicle terminal" is a new model of vehicle information service system.It brought new life to the industry.It has important research significance.This topic is aimed at the shortcomings of traditional vehicle information service system.For it can not fully meet the needs of users of the phenomenon.This paper designed a simple,convenient Android-based operating system and used in automotive tire monitoring of the Bluetooth signal transceiver system.The system not only real-time monitoring of tire tire pressure and temperature parameters and can achieve the tire alarm,the standard temperature and standard pressure settings.It can adapt to the complex environment.Its application is more flexible.It realizes the user's grasp of the real-time status of the car tire.It improves the safety of the car.The development needs of today's Tire Pressure Monitoring System(TPMS).To send and receive the Bluetooth signal as the focus of the study.Based on the system requirements analysis,the overall scheme of signal transceiver system based on Android Bluetooth is designed.This paper studies the underlying computer and Android client Bluetooth communication principle.This article designed the lower computer to send data packets and handheld Android client to receive data packets between the communication protocol.This article designed the lower computer to receive data packets and handheld Android client to send data packets between the communication protocol.This paper designed the underlying hardware circuit and the lower computer signal receiving and sending procedures.This article designed the hand-held Android client application to receive and send data programs and human-computer interaction interface and passed the final test of the software.The test results show that the system meets the design requirements.The system can realize the real-time monitoring of the temperature and pressure of the automobile tire,the alarm,the standard temperature of the tire and the setting of the pressure value.It has a good sense of user experience.It has a broad application prospects and significant social significance.
