【摘要】：随着电子信.息技术的发展、移动互联网的爆发式发展和物联网的提出,现有的汽车电子已远远的不能满足人们的需求。对于未来车联网的发展国外提出了车载信息服务系统(Telematics),它是远距离通信的电信(Telecommunications)与信息科学(Informatics)的合成词。本论文提出了一种基于S5PV210+Android平台的Telematics实现方案。该方案在实验室原有的“车载信息娱乐系统”之上进行了改进,并针对原有系统的不足该系统做了重新设计。论文对系统的整体方案、硬件设计、软件设计、操作系统移植以及对应的应用程序设计做了详细的介绍。为实现与司机的语音交互,本论文借鉴Android对于TTS(Text To Speech)框架的支持,使用讯飞语音包扩充了系统对于中文的TTS的支持。使用Google的Voice Control语音云服务来做对于语音命令的识别,可以实现语音控制音乐播放、辅助倒车等程序的控制。通过温度传感器和酒精传感器实时监控车内环境变量,当车内酒精浓度超过阀值时可以实现短信通知家人,及时的阻止酒驾的发生。并且通过OBD接口可以实时的监控车辆状态,可以对车辆故障等信心进行预警。同时扩展了RFID模块,可以实现近距离信息的获知。设计交互式车载短信功能,以解决行车时短信阅读和回复不方便的问题。
[Abstract]:With the electronic letter. With the development of information technology, the explosive development of mobile Internet and the Internet of things, the existing automobile electronics can not meet the needs of people. For the future development of vehicle networking, a vehicle information service system (Telematicsn) is proposed abroad, which is a combination of telecommunication telecommunications for remote communication and Informatics for information science. This paper presents a Telematics implementation scheme based on S5PV210 Android platform. The scheme is improved on the basis of the original "vehicle information entertainment system" in the laboratory, and the system is redesigned in view of the shortcomings of the original system. The whole scheme, hardware design, software design, operating system transplantation and corresponding application program design of the system are introduced in detail in this paper. In order to achieve voice interaction with drivers, this paper uses Android to support TTS text to speech framework, and extends the support of the system for Chinese TTS with iFLYTEK voice package. The voice control voice cloud service of Google can be used to recognize the voice command, which can realize the control of voice control music playing, auxiliary reversing and so on. The temperature sensor and alcohol sensor are used to monitor the environmental variables in the vehicle in real time. When the alcohol concentration in the vehicle exceeds the threshold value, the short message can be realized to notify the family and prevent the occurrence of alcohol driving in time. And the OBD interface can monitor the state of the vehicle in real time, and can alarm the confidence of the vehicle failure and so on. At the same time, the RFID module is extended to realize the close information. Design interactive vehicle short message function to solve the problem of short message reading and reply inconvenient.
