便携式S4海流计数据采集仪的设计与实现

为解决S4海流计在海上进行测量作业时,需携带计算机等诸多不便,研制出了便携式S4海流计数据采集仪。采集仪以Atmega128单片机为控制核心,利用Atmega128单片机的双路通用串行接口,同时采集S4海流计和PC机发送的数据,实现了数据的实时采集、存储和显示,便于事后数据处理和分析。本文重点介绍了采集仪的工作原理和具体软硬件实现方法。试验结果表明,该采集仪工作稳定,能够很好地满足采集要求。

Design and Realization of Portable Data Collection Instrument for S4 Ocean Current Meter

In order to overcome the inconvenience of taking PC when doing some measurements with S4 Ocean Current Meter,portable data collection instrument for S4 was made.Using Atmega128 as the controlling core,the instrument utilizes its double currency serial interface and collects data both from S4 Ocean Current Meter and PC as well,so real-time data collection,store and display are realized.This paper mainly introduces the working pringciple and the realization process of software program and hardware circuit in detail.The experiment results indicate that the collection instrument can work steadily and can meet the requirement of date collection very well.
