| 摘 要： | 基于北斗双模工作模式,设计一种将全海深海洋装备的地理位置信息提供给母船或控制中心的定位与通信系统。提出使用卫星无线电导航业务RNSS模式进行定位,并将位置及待传输信息通过卫星无线电测定业务RDSS模式发送至接收模块;采用光敏、倾角和温度多传感器组合冗余实现海洋装备作业环境的全天候有效检测,进而通过单片机控制北斗模块的休眠与唤醒及北斗系统RDSS／RNSS模式间切换。定位测试试验和马里亚纳海沟海试结果表明,所设计的全海深定位与通信系统不仅具有很高的快速定位成功率,而且能够有效节约电池电量和实现短报文信息传输。

| Abstract: | Based on the dual-mode working pattern of BeiDou satellites, a position and communication system is designed to transmit the geographic location of full ocean depth marine equipment to the mother ship or control center. This paper adopts the radio navigation satellite system (RNSS) model for positioning and the radio determination satellite service (RDSS) model for sending the location or the transmission information to the receiver’s module. Such system uses photosensitive, angle and temperature sensors combination redundancy working mode to achieve all-weather effective detection for marine equipment operating environment, and then controls the sleep and wake modes of the Beidou module, and the switch between RDSS or RNSS mode by single-chip microcomputer. The experiment results of both location test and sea trials in the Mariana trench show that the system proposed in this paper not only has a high success rate of rapid positioning, but also can effectively save power supply and realize the transmission of short-message communicating. |
