本研究的目的是开发一种太阳能自主水面航行器（SASV），用于海洋环境监测和海洋哺乳动物的水下被动声学监测。采用光学快速DO传感器的记录仪型CTD的测量项目有深度、温度、电导率、盐度、溶解氧、叶绿素和浊度。作者还开发了各种水下被动声监测系统（upams），用于建立海洋健康指数，为高速船只和鲸类避碰提供预防性安全措施。SASV的一个实际应用是监视群智能水下航行器。这款SASV由一对带有充放电控制器的太阳能电池板、一台嵌入式PC、一对推进器、一个GPS设备和一个用于导航的3轴数字指南针组成。SASV可以通过一个小游戏控制器在自主控制模式和手动控制模式下操作。这款体积小，重量轻，成本低的SASV的特点是易于操作和长期运行。本文介绍了该系统的设计思想、硬件组成、控制软件及试运行情况。
The purpose of this research is to develop a solar-powered autonomous surface vehicle (SASV) for the use of ocean environment monitoring and underwater passive acoustic monitoring of marine mammals. Measuring items of the logger version CTD with optical fast DO sensor are depth, temperature, conductivity, salinity, dissolved oxygen, chlorophyll and turbidity. The authors have also developed kinds of underwater passive acoustic monitoring systems (UPAMSs) for establishing a soundness index of the ocean, and contributing to preventative safety measures for collision avoidance of high-speed vessels and cetaceans. A practical application of the SASV can be watching over swarm intelligent underwater vehicles. This SASV consists of a couple of solar panels with a charge-and-discharge controller, an embedded PC, a couple of thrustors, a GPS device and a 3-axis digital compass for navigation. The SASV can be operated in autonomous control mode and manual control mode by a small game controller. Feature of this small-sized, lightweight and low-cost SASV is easy handling and long-term operation. This paper deals with its design concept, hardware components, control software, and trial run.
