船载自动气象站DTU通信机制及降耗方法探讨

Discussion on DTU communication mechanism and consumption reduction method of shipborne automatic weather station

使用DTU(Data Transfer Unit)通信是船载自动气象站与陆地上数据处理中心进行数据传输的一种方式。文章对DTU通信方式、参数配置、功耗进行了阐述,提出调整配置参数以降低DTU功耗的方法,从而降低船载自动气象站整体功耗,使其电力供应时间得到延长,为船载自动气象站在特殊天气情况下的工作提供有效供电保障。

Data transfer unit(DTU) communication is a way of data transmission between shipborne automatic weather station and data processing center on land.This paper describes the communication mode, parameter configuration and power consumption of DTU.A method to reduce DTU power consumption by adjusting configuration parameters is proposed, so as to reduce the overall power consumption of shipborne automatic weather station and prolong its power supply time, which can provide effective power supply guarantee for shipborne automatic weather station in special weather conditions.
