一种深水网箱鱼群状态监测的数据采集与远程传输技术研究

Research on Data Acquisition and Remote Transmission for Monitoring Fish in Net-cage of Deep Water

为了满足抗风浪深水网箱中鱼群远距离监测的要求,本文提出了一种鱼群监测数据采集和基于无线模块的远程传输方案.该方案由海上现场监测系统和岸上控制及显示主机构成.在海上现场监测系统中,单片机把采集到的回波数据存储到扩展存储器62256,再通过无线模块发送回岸上控制及显示主机,由主机对接收数据进行处理和显示.厦门海域的海上实验结果表明,该方案能够简便、有效地对深水网箱中的鱼群状态进行数据采集,并在距网箱500 m的距离内实现数据的可靠传输和显示,为正在新兴发展的抗风浪深水网箱养殖提供了一种简单、有效的鱼群状态安全监测技术.

In order to monitor fish in deep-sea cage far from the shore,a remote data acquisition and transition system based on wireless module is developed. The system consists of local devices on sea and a host computer on shore. In this system,echo data is collected and stored in external RAM 62256 by mcu on the local device and the remote wireless transmission to host computer is realized in wireless module. Finally Data analyzing and result displayed is processed on the host computer. The experimental results demonstrate that the design makes gaining of monitoring data more convenient. It can precisely get and process echo data from local device which is fixed on the net-cage and within 500 meters from the shore. So it provided a simple and effective plan for monitoring fish in deep-sea cage with heave sea resistance.
