摘要：

基于我国自主研发的北斗卫星,设计了一套潜标数据回收系统,采用卫星通信方式对潜标数据进行实时传输,卫星通信方式选用北斗一代卫星进行数据传输。由主控芯片STM32L控制系统工作状态,通信定位芯片RD0538对位置信息进行采集并解析,最后将待传回数据和定位数据通过北斗一代卫星进行报文传输。测试结果表明,该系统定位精度误差符合海上使用要求。该系统结构简单、占用体积小,用户可以设置系统发送频率。对该系统进行降低功耗的改进后,可将其工作时间延长至9天。

Abstract:

A set of submarine data recycling system was designed based on the Beidou satellite independently developed by China. The main control chip STM32L was responsible for controlling the working status. The communication positioning chip RD0538 collected and analyzed position information. Finally, the data to be transmitted back and the positioning data were transmitted through the Beidou first generation satellite. The test result showed that the positioning accuracy met the requirements for maritime use. The system had a simple structure and a small size, and the user could set the system transmission frequency.By reducing the power consumption, the system was able to extend its working time to 9 days.

Key words: Beidou satellite, short message, date recycling, low power, submerged buoy, satellite communications
