基于ARM的水下目标定位系统的通信模拟系统设计

水下目标定位系统被广泛应用于水下目标的定位和跟踪、水声对抗等水声领域,其系统主要由水声浮标阵、中继站和基站等构成,浮标与基站的通信通过无线网桥进行传输。为了提高该系统的通信可靠性和智能性,采用ARM板作为中继站和通信服务器,以一台电脑作为基站的显控机,一台电脑模拟浮标,设计了一种水下目标定位系统通信模拟系统,其中ARM板搭载LINUX嵌入式系统。该模拟系统可以实现基站和浮标之间的中继通信,完成从基站显控端发送各种命令和参数到ARM板,ARM板进行中继转发给浮标,浮标收到命令后进行响应,并回传相关数据至基站显控端的功能。

Design of communication simulation system of underwater target positioning system based on ARM

The underwater target positioning system has wide application in the undersea acoustic field, such as positioning and track of an undersea target, and underwater acoustic countermeasure. The system is consisted of an underwater acoustic buoy, a relay station and a base station. The communications between the underwater acoustic buoy and base station are over microwave. A communication simulation system of the underwater target positioning system is designed based on Linux embedded system to improve communication reliability and intelligence. In this communication simulation system, ARM development board is used as relay station and communication server. One computer is used to simulate display and control equipment of the base station and the other one is used to simulate the underwater acoustic buoy. The communication simulation system can complete relay communications between the base station and underwater acoustic buoy. In this system, various orders and parameters can be transmitted to the underwater acoustic buoy from the base station by relay station. When the underwater acoustic buoy received the orders, the dates of the underwater acoustic buoy will be transmitted to the base station also by relay station.
