| Abstract: | 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. |
