摘要/Abstract

摘要： 为改善海上深水网箱监测中系统体积大、移动性差的问题，本文基于ARM LPC1788嵌入式控制技术，开发了一套便携式深水网箱鱼群远程声学监测系统。该系统主要包括三个功能主体：深水网箱声学探测终端、用户便携式监控终端以及远程数据传输模块。首先网箱探测端采用200kHz的脉冲探测信号，回波信号经信号检测与采集后通过无线数据传输模块实时传送至用户监控终端；用户监控端将获得的结果通过7寸液晶屏幕进行显示。实验结果表明，基于嵌入式的用户监控端具有操作简便，移动性好，信息显示清晰明确等优点，与无线传输模块相结合，可在2000m的开阔范围内进行监测工作，更好的实现网箱鱼群监测工作实施的机动性和优越性。

Abstract: In order to realize the monitoring of offshore cage fish more flexible and mobile, a portable remote monitoring system is designed based on ARM embedded in this paper. It is composed of three major functional subjects: net-cage acoustic detecting terminal, portable monitor terminal and wireless transmission module. Firstly, net-cage detecting terminal emits an acoustic signal by the transducer, which is a short pulse (duration 0.2ms) single-frequency (200kHz) sinusoid, and collects the data of the echo envelope by an analog-to-digital converter. Then, the collected data is send to the portable monitor terminal in real time by wireless transmission module. To make it easier for providing the detection result to the user, the echo signals are displayed as an echogram on the 7-inch liquid crystal display screen. The experiment has been conducted to verity the good performance of this system. The powerful portable monitor terminal can meet the high maneuverability and superiority requirement of monitoring.
