中文摘要： 针对我国近海海洋生态环境浮标监测集中于海面和海底的现状，项目在申请单位现有表底层实时监测浮标的基础上，通过集成创新方式解决水下温跃层数据的传输技术问题，在保证浮标系统安全性不受影响条件下将水下跃层测量数据实时传输至水面浮标平台中，从而实现对近海水体的全剖面5层实时监测。跃层数据的实时传输利用感应耦合与水声通讯相结合的无线通讯方式实现，通过选用并组合成熟技术设备、增加数据集成处理单元和改造浮标系留布局等工作，建立有线电缆最少化的跃层数据集成与通讯子系统。 项目着眼于技术设备的工程应用创新，新增的跃层数据实时传输子系统将不影响浮标原有的安全性和稳定性，集成时选用现有海洋常用设备，潜在用户基本可以较低代价方便地将此功能集成于已有的各类水质监测浮标系统中，从而提高监测能力，更好地服务于科学研究和社会需求。

英文摘要： Owing to the fact that the buoy monitoring for coastal ecosystem is focus on the surface and bottom, this study aims to transmit the data in thermocline to surface buoy which is already able to acqiure tha data at surface and bottom, through resolving the key technical points in the way of integration innovation. Thus, the buoy would get the data in five layers in real-time without lossing the safety performance. The data transmition from thermocline to surface will be achieved by the way of integrating inductive telemetry with acoustic communication. We bend ourself to set up an effective module for data integration and communication by assembling instruments, integrating data logger and improving mooring style. This study is focus on the innovation in engineering application of marine technologies and instuments. The thermocline data integration and communication module will be integrated with marine general equipments without lossing the safety and stability of the buoy. Therefore, the module will be easily applied in the existing buoys with very low cost. We hope that we will improve our ability to service scientific research and socail requirement by accomplishing this work.
