基于RCM5700的分布式仪表设计

摘要

With respect to the requirement of simulator, using RCM5700, which has high performance, low power and low cost, combined with control of stepping motor technology, designed a simulate instrument, RCM5700 simplified circuit design and develop environment, optimized software programming, This system full utilized high bandwidth, high scalability, simple structure, low-cost feathers of the Ethernet. Base on enough experimentation, this instrument had advantages of high performance, good stability and expandability. The scheme of system structure, software and hardware were described in detail.%为了满足飞行模拟器的需要，利用RCM5700能够支持快速以太网技术开发、具备较强性能的特点．结合步进电机控制设计了模拟器所需要的仿真仪表；优化了系统编程；数据传输部分充分利用了以太网带宽大，可扩展性强，结构简单，成本低廉的特点。通过实践检验，该仪表设计具有指示精度高、实时性好、速度快等优点。文章详细介绍了仪表的组成、工作原理以及软硬件设计。
