摘要
针对常规定位系统接收到的位置信号间产生干扰,导致实时定位结果误差较大,针对该问题,设计一种电子海图的舰船远海航行中实时定位系统。硬件部分设计舰船位置信号接收装置,构建实时数据转换电路结构。软件部分将相同信号强度划定为相同区域范围后,构建电子海图定位算法,使用JAVA编程实现定位数值的实时共享,完成定位系统的设计。搭建测试结构后,调试测试架构性能,测试2种常规定位系统与设计的定位系统,测试结果表明:设计的定位系统最终的定位误差结果最小。
In view of the interference between the position signals received by the conventional positioning system,which leads to a large error of the real-time positioning results, a real-time positioning system based on electronic chart is designed for ships sailing in the far sea. The hardware part designs the ship position signal receiving device and constructs the real-time data conversion circuit structure. In the software part, after the same signal strength is divided into the same area,the electronic chart positioning algorithm is constructed, and the real-time sharing of positioning values is realized by using Java programming to complete the design of the positioning system. After the test structure was built, the performance of the architecture was tested, and the two conventional positioning systems and the designed positioning system were tested. The test results showed that the positioning error of the designed positioning system was the smallest.
