摘要

为满足搭载平面反射镜的高精度二轴机械转台为核心的激光点目标球幕投影系统仿真目标点的时间精度与位置精度要求,提出在具有高实时性和时间精度的RTX (real-time extension)64实时扩展系统环境下开发和运行的计算机控制软件的设计方案。使用实时CAN总线通信与以太网结合的通信控制方法,实现各子系统之间的数据通信和协同控制,提升运动目标模拟的位置精度和时间精度。在20 ms的同步控制时钟周期下,重复实验中模拟目标点的误差最大值分别为0.005 34°与0.004 04°,符合激光点目标球幕投影系统的模拟精度要求,证明该实时控制软件的设计方案可行。

Abstract

In order to satisfy the time and position accuracy requirements of the simulated target point for the laser spot target dome projection system which takes the high-precision two-axis mechanical turret with a planar mirror as the core, a design scheme of computerized control software that running in RTX64 real-time extended system environment with high real-time and time accuracy. This design scheme combines the real-time controller area network (CAN) bus with Ethernet to realize data communication and cooperative control among subsystems. Meanwhile, the position accuracy and the time accuracy of moving target simulation are effectively improved. Keep the clock synchronization period 20 ms, in the experiment, the maximum errors of the simulated target point are 0.005 34° and 0.004 04°, respectively. The errors meet the simulation precision requirement of the laser point target spherical screen projection system, which proves that the design scheme of the real-time control software is feasible.
