摘要
光电头盔性能测试系统主要用于头盔瞄准系统的地面测试。以该系统为研究对象,结合其应用,明确以位置控制为核心的功能指标,提出硬件采用上下位机的结构模式。根据其功能需求,基于模块化设计思想,设计了模块化的控制系统层次结构。为了提高控制系统的定位精度,减少机械误差的影响,提出误差的分段软件补偿方法。对于用户单位与指令单位转换过程中出现的精度损失,采用四舍五入的处理方法,降低了误差出现的概率。通过原点开关定位与Z脉冲的双重寻零,可以获得高精度的原点定位。采用管理层与执行层分离的设计方法可以实现用户的系统定制。现场的实际测试表明:该系统运行定位稳定可靠,功能完善,安全性高,达到了预期效果。
Electromagnetic helmet test system is used to make ground test for helmet aiming system. Taking this system as re- search object, combining with its application, function indexes centered on position controlling were determined, a architecture mode of hardware system was proposed. According to its function desire, based on module design idea, modularized architecture for this system was designed. To promote the positioning accuracy and decrease the influence of mechanical error, a software compensation method for the error of each section was put forward. For the accuracy loss of conversion between user unit to instruction unit, a pro- cessing method using rounding was adopted to decrease the error probability. By two homing methods of home switch and Z pulse, a high homing accuracy was achieved. A design method that management layer and executing layer were separated could be used to real- ize the system custom of user. The practical test in the lab proves that this system runs steadily and reliably. It has perfect function and high security and the goal is reached.
