摘要
普通船舶导航信息处理系统,不能在最短时间完成导航信息分类处理,且极易发生船舶信息丢包现象。为解决上述问题,设计基于DSP技术的嵌入式数字船舶导航信息处理系统。通过DSP船舶导航图像处理硬件系统框架设计、信息同步子模块设计,完成系统硬件设计。通过导航信息系统嵌入式通信串口设计、多任务调度流程设计、通信协议设计,完成系统软件设计。模拟系统应用环境,设计对比实验结果表明,新型数字船舶导航信息处理系统,与普通系统相比,大幅缩短导航信息分类处理所需时间,降低船舶信息丢包现象发生几率。
The navigation information processing system of general ship can not complete the classification and processing of navigation information in the shortest time,and it is very easy to lose the packet of ship information.In order to solve the above problems,an embedded digital ship navigation information processing system based on DSP technology is designed.The system hardware design is completed through the design of the hardware system framework and the information synchronization sub module of the DSP navigation image processing system.Through the design of the embedded communication serial port,the multi task scheduling process and the communication protocol design,the system software is designed.The simulation system application environment and design contrast experiment results show that the new digital ship navigation information processing system greatly reduces the time needed to classify and process navigation information,and reduces the probability of ship information packet loss.
