基于单片机的弱荧光测量仪系统设计

摘要

本文通过简要分析直流程控增益放大器的原理,介绍了一种采用单片机AT89C51为主控制器的弱荧光测量仪系统设计方案,具有功耗低、精度较高、操作方便等特点.%Through a brief analysis of the theory of the direct current gain-programmed amplifier, this paper introduces the system design schema of a weak fluorescence measuring apparatus which uses the single-chip AT89C51 as the main controller. It has its own features, such as low power dissipation, high precision, easy operation and so on.
