中文摘要：

针对浮标技术在海洋环境监测中的应用，研究并改进了现有的浮标系统，设计并实现了自升降式浮标控制系统，以获取水下不同深度的环境数据，具有很好的安全性和隐蔽性。系统以MSP430处理器为核心，以Si4432为无线收发模块，结合温湿度、光照、加速度、倾角、CTD、溶解氧传感器和SD卡，实现了对海洋数据的采集、存储和传输。经测试，能可靠地将数据传输至岸基模块，满足了设计要求。

英文摘要：

Aimming at the application of the buoy technology in the ocean environmental observation, the conventional platform was updated by including a self-lifting buoy control system, in order to collect the underwater environmental data simultaneously in dif]~rent depth, and to satisfy the security and concealment. The data-collection system consists of MSP430 as MCU, Si4432 as wireless module, SD card as storage medium and several sensors such as the sensors of temperature and humidity, illuminometer, accelerators, inclinometer, CTD and dissolved oxygen analyzer. All the functions including data collection, data storage and data transmission were been realized. The communication test showed that, the data from the system could be transmitted to shore station in reliability, which could meet the requirement of the design.
