基于ARM-Linux的自动站设计

Design of automatic weather stations based on the ARM-Linux

针对目前使用的气象观测自动化程度低,实时性差的问题,本文提出了基于ARM-Linux的气象自动站设计方法,介绍了基于ARM-Linux的气象观测系统的总体结构和CAN总线控制和通信的实现。软件系统主要包括Linux驱动程序和应用程序。硬件主要包括ARM芯片,CAN总线控制器和传感器。该系统易操作,低成本,高性能,具有广泛的应用前景。

Aiming at the problem of the current use of the Automatic weather stations （AWS）weak degree of automation,poor real-time,this paper proposes a design of intellectualized Automatic weather stations which based on the ARM-Linux and CAN （Controller Area Network）Bus. This illustrated intellectualized AWS＇s gross structure, realization of CAN Bus control and communication. The software system mainly includes the Linux device driver and Application procedure, and the hardware system includes ARM, CAN Bus controller and sensors. From experience, the characteristics of the system are convenient to debug, small, lost-cost, high-prerformance, and it has the wide prospect of application.
