基于LPC1769的特种纤维强密度检测系统设计

摘要

Special fiber is a kind of chemical fiber which has special physical and chemical structure,performance and usage,or has special functions.As its special performance,it is applied to some fields of the industry,national defense,medical care,environmental protection and the advanced science.Considering how to detect density of the special fiber,the paper designs a detection system for density of special fiber based on LPC1769.The NXP's LPC1769 microprocessor,EE-SX1042 mini EO sensor,UV sensor and the stepper motor driver A3967SLB drive circuit are used in the hardware of the system.EE-SX1042 mini EO sensor is used to detect the density of special fiber.The application shows that the system has high sampling accuracy,good real-time,low cost,and stable and reliable performance.%特种纤维是具有特殊的物理化学结构、性能和用途,或具有特殊功能的化学纤维,由于它的特殊性能,广泛应用于工业,国防,医疗,环境保护和尖端科学各方面.针对如何检测特种纤维密度的问题,设计了一种基于LPC1769的特种纤维密度检测系统.该系统的硬件部分主要采用NXP公司的LPC1769微处理器,微型光电传感器EE-SX1042以及A3967SLB步进电机驱动电路,EE-SX1042微型光电传感器用于检测特种纤维密度.应用实践表明,该系统采样精度高,实时性好,成本低廉,且性能稳定、可靠.
