导航雷达图像显示的多线程编程

摘要

The software of displaying the navigational radar images on SoPC platform was designed. The task of code was divided according to the system running engineering and radar image display task which includes radar circle and character data. The divided code task includes hardware initialization, data sampling, range set, window display and system shutdown.Corresponding to the divided task, a method af multi-thread programming in Windows OS was taken to compile the software for the radar image display. The results of the software ruuning on the SoPC platform indicates that it can meet the needs of the navigational radar image display.%设计了导航雷达图像在SoPC硬件平台上显示的软件系统,根据雷达图像显示任务和系统的运行工程对代码的任务进行划分,雷达图像显示任务包括雷达圆和文字数据两部分,划分后的代码任务包括硬件初始化、开始数据接收处理、量程设置、窗口显示、关机等5个任务,对应划分后的任务采用了Windows下的多线程方法编写雷达图像显示的软件系统.经过在SoPC硬件平台上调试运行,效果显示能够满足导航雷达图像显示的各项要求.
