摘要
激光粒度仪是一种应用广泛的颗粒测量仪器。文中提出采用DSP和ARM嵌入式系统的设计方案,取代传统激光粒度仪所采用的数据采集卡,PC机,意在实现激光粒度仪的小型化,低成本。阐述了粒度仪数据采集系统的硬件组成,工作原理,电路的设计。设计提高了粒度仪的抗干扰能力和测量精度。
As measuring instrument for particle laser particle size analyzer are applied widely. DSP and ARM embedded system for laser particle size analyzer are proposed, which replaced the data acquisition card and PC in the conventional laser particle size analyzer to realize miniaturization and low cost. In this article introduced hardware structure and principle of the data collect system and circuit design. Laser particle size analyzer＇s anti-interference ability and the precision of measurement are enhanced.
