基于INtime的雷达实时操控显示终端设计

Design of Radar Real-time Operation Control Display Terminal Based on INtime

为了解决雷达操控显示终端的强劲的图形显示能力与实时性能相结合的问题,本文提出了一种在XPE下基于INtime实时扩展的雷达实时操控显示终端设计方案。通过INtime实时进程完成雷达实时控制、数据处理等实时任务,通过Windows进程完成雷达目标、原始视频、状态数据等的快速显示,利用INtime的共享内存和信号量机制实现两之间通信。经过测试与仿真以及与雷达实装的现场试运行,验证了该方案的适用性。

In order to solve the problem of combining strong graphics display capabilities of radar operation control terminal with real-time performance, a radar real-time operation control display terminal design plan based on IN-time in XPE to perform real-time extension is presented. The real-time tasks such as radar real-time control and data processing by INtime real-time process are accomplished ; the task of fast display of radar target, the original video and state data by Windows process is completed. The communication between two sides is fulfilled based on share memory of INtime and semaphore mechanism;and the test, simulation and onsite preoperation of real installed on radar verify the adaptability of this plan.
