【摘要】：海洋监测技术是海洋技术的主要组成部分,是海洋资源开发的技术支撑,为海洋环境综合治理和防灾减灾提供技术手段和科学依据。基于浮标的海上无线监测系统是海洋监测的主流手段之一。本文针对现有浮标监测系统浮标节点间通信距离的不足,并结合海洋监测的应用需求对基于浮标的监测系统进行研究和开发。 本文首先提出了一种基于波束成型技术的浮标间远距离通信方法,并在规则波条件下进行仿真,验证了本方法的天线增益效果。其次,根据我国海域的海洋监测应用需求,开发了基于ZigBee和General Packet Radio Service (GPRS)技术的无线通信网络样机。然后,完成了水下多通道数据采集系统的开发,并针对海底观测网项目需求开发了科学仪器插座模块(Scientific Instrument Interface Module, SIIM)远程数据采集系统,为后续的数据采集系统开发提供参考。最后完成了水下多通道数据采集系统和SIIM远程数据采集系统的组装和调试。 本文所研究的基于浮标的海洋监测系统,为我国海域实现全方位实时海域监测提供重要支撑。
[Abstract]:Marine monitoring technology is the main component of marine technology, is the technical support of marine resources development, and provides technical means and scientific basis for comprehensive management of marine environment and disaster prevention and mitigation. Marine wireless monitoring system based on buoy is one of the main methods of ocean monitoring. Aiming at the deficiency of communication distance between buoy nodes in the existing buoy monitoring system, this paper studies and develops the monitoring system based on buoy combined with the application requirement of ocean monitoring. In this paper, a method of long-distance communication between buoys based on beamforming technology is proposed and simulated under regular wave conditions, which verifies the antenna gain effect of this method. Secondly, a wireless communication network prototype based on ZigBee and General Packet Radio Service (GPRS) technology is developed according to the application requirements of marine monitoring in China's sea area. Then, the development of underwater multi-channel data acquisition system is completed, and the scientific instrument socket module (Scientific Instrument Interface Module, SIIM) remote data acquisition system is developed to meet the requirements of submarine observation network project, which provides a reference for the subsequent development of data acquisition system. Finally, the assembly and debugging of underwater multi-channel data acquisition system and SIIM remote data acquisition system are completed. The ocean monitoring system based on buoy is studied in this paper, which provides important support for the realization of all-round real-time sea area monitoring in our country.
