基于ARM9的船载海水监测系统设计

为满足对海岸线水域监测海量数据的需求,设计一种随航船运行的海水参数测量系统。该系统在ARM9平台上,对电源、通信接口、控制接口及A/D等硬件电路进行了扩展,并通过EVC 4.0编写的应用程序实现自动控制,依次完成对水质参数的测量,对GPS定位参数的读取,通过GPRS短信发送终端将数据发送到数据中心,以及将数据存储在机带SD卡中等工作。系统可同时完成8路A/D转换,适于多种海水参数的测量,体积小,应用灵活,且自带LCD触摸屏,操作方便。由Visual Studio 2010中C#编写的数据中心PC程序,是整个系统的一部分。以GPRS为载体,实现了远程数据传输及简单的远程控制。

Design of FerryBox: ARM9-based shipborne automatic monitoring system of coastal waters

In this paper,a fully automated measuring system on ferries or ships-of-opportunity,called FerryBox,is designed to monitor and analyze mass data collected from coastal waters.The circuits of hardwares such as power port,communication interface,control interface and AD are extended on the ARM9 platform.And by application program written in EVC4.0,the system realizes automatic control,which accomplishes multiple steps: measuring seawater quality,reading GPS locating parameter,sending data to the data center by GPRS,and storing data on SD-card in order.The system can implement A/D converter of 8 channels,and is suitable for the measurement of seawater multi-parameter.With a LCD touch screen,it is small in size,flexible in application,and convenient to operate.The PC program,used in data center,which is written in C# on Visual Studio2010,is part of the whole system.Taking GPRS as a carrier,the system achieves remote data transmission and simple remote control.
