深水网箱鱼群监测仪中数据采集系统的研究

Study of a Data Acquisition System for Shoals Monitor in Net-cage of Deep Water

为了实时采集和处理深水网箱中鱼群动态监测数据,提出了在LabVIEW平台上用EPP并行口采集数据,并在微机中处理的研究方案.实验结果表明:本研究开发时间短,编程效率高,能够实时准确的采集处理水下鱼群信号,取得了较满意的实验结果.本方案除适用于海洋外还可以推广应用于其他野外作业中.

In order to acquire and process monitoring data of shoals in net-cage of deep water in real time, a data acquisition system design with EPP based on LabVIEW was proposed. The results demonstrate that the design makes signal process more convenient and rapid. It can precisely get and process echo data of shoals in real time. We have got the satisfied results. It is applicable to sea and many other outdoor occasions.
