基于Cortex-M3的屏蔽门门体运动检测系统设计

摘要

Considering the characteristics of the door body movements of the platform screen doors ,the paper designs a test system for the door body movements by adopting LM3S8962 chip. This system is cost effective,convenient and flexible in functions. The paper describes the system application characteristics, introduces the overall design scheme, explains the modular hardware circuits in detail and illustrates the main points in software programming. This system is of value and wild application prospects.%　　针对屏蔽门门体运动的特点，采用了Cortex-M3内核的LM3S8962芯片，设计了一种性价比高、使用方便、功能灵活的门体运动检测系统，描述了系统的应用特点，给出了系统的总体设计方案，详细介绍了模块化的硬件设计电路，阐明了软件程序编写时的要点，有着一定的应用前景和价值。
