基于Windows平台的实时信息处理方法

Real-time Information Processing Method Based on Windows Platform

摘要:

微软的Windows操作系统由于具备良好通用性、图形用户界面以及众多的技术支持基础而成为测试设备的首选解决方案,但基于抢占式多任务调度策略就决定了Windows系统的非实时性属性,对于实时性要求较高、时序控制要求严格的武器系统测试,Windows系统系统不适于作为地面测试使用。针对基于Windows平台武器地面测试设备存在的非实时性问题,提出了一种排他性线程独占技术和高精度软时钟技术,可以实时处理以太网、串口等IO信息,低成本且低复杂度的解决武器地面测试设备的实时性问题,进一步保障武器系统测试的准确性和可靠性。

Abstract:

As good versatility, graphical user interface and numerous technical supporting foundations, Microsoft Windows Operating System has become the preferred solution for ground test equipment of weapon. However, the preemptive multi-task scheduling strategy determines the non-real-time property of Windows system, which is not suitable for ground test of weapon system with strong real-time performance. Aiming at the non-real-time problem of weapon ground test equipment based on Windows platform, this paper presents an exclusive thread exclusive technology and high precision soft clock technology, which can processes I/O information in real time such as Ethernet and serial port and et al. This method can realize the real-time problem of ground test equipment with low cost and complexity.
