基于Android车载终端的设备管理框架设计

Design of device management framework based on Android in vehicle terminal

为了实现对Android车载终端平台新增的许多非Android原生系统中的外围设备进行统一管理,本文提出了一种基于Android Local Socket和Service的设备管理框架。该设备管理框架的整体层次结构包括应用程序、设备管理服务、守护进程、设备功能动态库、内核设备驱动,以及设备硬件等多个层次。实际应用表明,该设备管理框架逻辑结构清晰,能够较好地支持上层和底层的数据互通,有效地将Android系统中非Android原生的设备进行统一控制和管理,显著提升了设备系统的稳定性,达到了设计要求。

In order to manage the devices which are not in the primary system of Android, a framework for management of devices which based on Local Socket and Service is proposed. The framework of the overall hierarchical structure consists of the application, the service for management of peripheral devices, the guardian process, the dynamic library for devices, the kernel device drivers, the device hardware, and so on. Practical application shows that the framework for management of peripheral devices have many advantages, including the clear framework of logic structure, better to support the data interoperability between upper layer and bottom layer, effectively control and manage the peripheral devices which are not in the primary system of Android. The stability of the system is significantly improved, and the design requirement is achieved.
