摘要
针对北斗通信效率低、通信并非百分百可靠等问题,提出了一套新的大型海洋浮标北斗通信机制,包含一套通信协议、一种适用于通信数据的"位拼接-LZW"两重数据压缩机制以及一套适用于通信系统的"主-从"两重状态机通信控制机制。该机制有效地提高了通信传输效率,节约了通信成本,保证了北斗通信的可靠性,并且已成功应用于大型海洋浮标中。
For the problems such as low communication efficiency and unreliability of communication, a new communication mechanism for large buoy based on Beidou satellite was proposed, including a set of communication protocols, a double data compression mechanism called ＂bit splicing-LZW＂ for communication data and a ＂master-slave＂ double state machine communication control mechanism for communication system. The mechanism could improve the communication transmission efficiency, save communication cost and ensure the reliability of communication. The mechanism has been successfully applied to the large buoy.
