光电效应实验智能装置的设计

An intelligent device test design for photoelectric effect

介绍了一种光电效应实验智能型装置,阐述了利用单片机系统组建一个智能仪器实验系统的实现方案;给出了系统总体框图和软件程序流程图;阐述了实验测量的工作原理;提出同时用零点法和拐点法测量的方案;解决因测量时间长、环境的变化对仪器测量精度的影响问题;避免主观随意性,减小实验误差,减少微弱光电流受干扰的几率,达到即快速又准确的测量目标。

An intelligent device applied in photoelectric effect experiment and a implementation scheme using chip microcomputer- based system to establish the intelligent device experiment system were introduced. The system schematic diagram and the operating measurement principle were illustrated also. It was proposed using the measure plan method of Zero and inflection point simultaneously, to solve the accuracy problems of long time measuring and environment exchanging, to reduce experiment error and disturbed opportunity of weak photoelectric current, to actualize rapid and accurate measurement.
