基于嵌入式Linux的车载监控系统

Vehicle Monitor System based Embedded Linux

介绍了一个用于汽车环境的嵌入式监控系统。系统包括两个模块:用户交互模块和汽车监控模块。其中用户交互模块的主要功能是显示汽车监控模块传送过来的汽车状态,并负责完成用户与监控模块的交互。汽车监控模块的主要功能是监视车内主要部件的状态,并在部件状态发生改变时能对其做出相应的控制,同时通过无线网络与监控中心通讯。本系统使用Minigui来实现用户界面模块,使用串口通讯技术完成与汽车部件的交互,使用802.11b无线局域网完成与监控中心的通讯。

It introduce a embedded monitor system used in the car environment. The system includes twomodules ：user interactive module and car monitor module. The key function of the user interactive module is to display the car status which is transmitted from the car monitor module. The car monitor module monitors the status of the main components in the car. It will take corresponsive control when the status of the components changes, and communicate with the monitor center by wireless network. Our system uses Minigui to accomplish user interface module, serial communication technique to accomplish the interaction of the car＇ s components and 802.11 b wireless LAN to accomplish the communication with the control center.
