项目摘要

This research is to realize the oceanic sensor network including the sensor node in underwater and bottom of the sea at shallow water area near harbor based on highly accurate location information. As a result of the investigation at first year about similar research on land where many systems has been developed and evaluated, the research object was shifted from a ubiquitous environment to the sea field where the research results were little.The main result is as follows. Especially, it is given priority in the sensor network research that uses highly accurate GPS that can be achieved in the ocean.1. Ubiquitous, wireless network in larger areaThe density of marine sensor network nodes was sparse, and the distance between nodes for marine sensor network at sea is longer than on land. The long distance PAN was evaluated, and the original very low power communication of about 300m was enabled by GPS synchronous method and efficient Crystal filter narrowband SS method.2. Highly accurate measurement with low end L1,CAGPS/antennaThe possibility of RTK GPS by using L1/CA GPS module u-blox 4T was evaluated by original software in the vicinity of the surface of the sea. The fix success rate of 30-40% was obtained for one second by a single epoch Kinematic GPS method.3. Practical use research on supersonic wave communication in shallow water areaThe buoy was designed, which was produced to compose the sensor network node where the supersonic wave in water had been used, and it experimented on the sending and receiving wave in region of about 2m in depth. To exclude the influence of phasing, the FSK method is adopted. Because of rapid change and many multipath wave from sea surface and from the bottom, the communication DFE (Decision Feedback Equalizer) method was used.4. The position estimation of sea bottom sensors.Research of autonomous navigation by MEMS was started. and MEMS sensor was evaluated as first step. These study will be continued.

本研究的目的是实现基于高精度定位信息的海洋传感器网络，包括位于港口附近浅水区域的水下和海底的传感器节点。由于第一年在开发和评估了许多系统的陆地上进行了类似研究，因此研究对象从普遍存在的环境转移到研究成果很少的海洋领域。主要结果如下。特别是，它被优先考虑在传感器网络的研究，使用高精度的GPS，可以在海洋中实现。1.海洋传感器网络节点密度稀疏，海上传感器网络节点之间的距离比陆地上长。对长距离PAN进行了评估，采用GPS同步方法和高效的Crystal Filter窄带扩频方法实现了原有的300 m左右的极低功耗通信.使用低端L1，CAGPS/天线进行高精度测量使用L1/CAGPS模块u-blox 4 T进行RTK GPS的可能性在海面附近使用原始软件进行了评估。单历元动态GPS定位方法获得了30-40%的1秒定位成功率.超声波通信在浅水区域的实际应用研究设计了浮标，制作成传感器网络节点，利用水中超声波进行通信，并在水深约2 m的区域进行了收发波实验。为了排除相位的影响，采用FSK方法。由于海洋环境变化快，海面和海底多径波多，采用了通信DFE（Decision Feedback Decisionizer）方法.海底传感器的位置估计，MEMS自主导航研究开始。并对MEMS传感器进行了初步评价。这些研究将继续进行。
