摘要
抛弃式温度剖面测量系统(Expendable Bathy Thermograph,XBT)是一种可在测量船航行状态下进行海洋温度剖面测量的测量仪器,它具有实时、快速和低成本的特点,广泛地应用于大洋科学考察和海洋物理特性研究。基于时分多址原理设计了机载抛弃式温度剖面测量系统(Airborne Expendable Bathy Thermograph,AXBT),该系统允许8个AXBT浮标同时工作,可以大幅度提高测量效率。给出了AXBT机载单元和AXBT浮标的硬件设计,并根据AXBT浮标温度测量的特点给出了通信时隙分配方案和数据冗余编码方案。最后给出了AXBT系统湖上试验结果,试验结果表明AXBT系统工作稳定可靠。
The Expendable Bathy Thermograph（XBT） is a measuring instrument for the temperature profile of sea water.Because of its advantage of real-time,fast measuring and low cost,XBT is widely used in ocean survey and physical property research.Based on TDMA principle,the system design of airborne Expendable Bathy Thermograph（AXBT） is reported in this paper.The hardware design of airborne receiver unit and the AXBT buoy are also reported.The time slot allocation scheme and redundant encoding of temperature data are carefully designed.The test of AXBT system on the lake indicates that the AXBT system is reliable and stable.
