某导弹仿真训练系统分布式控制器的设计与实现

A Universal Distributed Controller for a Missile Simulation Training System

针对某导弹训练系统实际需求,设计了一种基于485总线的一主多从分布式测控系统通用控制器,给出了微控制器、RS-485总线接口、A/D转换、I/O扩展和LCD驱动接口电路及控制器软件的实现方法.系统联调和测试结果表明,该控制器功能齐全、性能稳定,具有一定的通用性,可用于其它训练系统.

Aimed at designing a missile simulation training system, a one-master and multi-slave distributed system based on RS-485 bus is adopted. Considering the training requirements, a universal controller hard- ware including circuits of micro control unit（MCU）, RS-485 bus, analog to digital, I/O expander and LCD driver is designed and the software realization is given. The experiment results indicate that the capability and performance of the controller meets the design requirements, the controller has powerful universal characteris- tic and can be applied to other simulation training system design.
