光电跟踪系统控制器硬件设计

摘要

In order to improve the performance of the controller of the optical tracking system, the hardware part of the optical tracking system controller is designed. Firstly, the optical tracking system controller hardware circuit diagram is presented. Then the minimum system is introduced, including memory expansion, the external clock, reset circuit, power circuit, the CPU board interference analysis and other parts of the design. Finally, elaborate design of analog module, digital module and communication module in detail. Using the controller not only enhanced the flexibility and adaptability of the optical tracking system to ensure system performance requirements, but also has a good real-time.%为了提高光电跟踪系统控制器的性能，文中对光电跟踪系统控制器的硬件部分进行了设计。首先给出光电跟踪系统控制器硬件电路框图。接着介绍最小系统的设计方案，其中包括存储器扩展，外部时钟，复位电路，电源电路，CPU板的抗干扰分析与设计等部分。最后对模拟量、数字量模块和通信模块设计进行了详细阐述。采用该控制器不仅增强了光电跟踪系统的灵活性和适应性，保证了系统性能要求，而且还具有良好的实时性。
