摘要
惠斯通电桥电路是大学物理教学中一个基本实验电路,其广泛应用于电阻、温度、压力、频率等物理量的测量,受制于实验设备和学生基础知识的局限,往往实验开展效果不是很好.该设计采用Proteus仿真软件结合AT89C51单片机对惠斯通电桥测温电路进行仿真,较好地阐述了实验原理和展示整个实验的过程,对大学物理电路部分的教学具有一定的帮助.
Wheatstone bridge circuit is a basic experimental circuit in college physics teaching. It is widely used in the measurement of resistance, temperature, pressure, frequency and other related physical quantities. Subject to the limitations of the experimental equipment and the basic knowledge of students, often experiment to carry out the effect is not very good. The design is the use of Proteus simulation software and AT89C51 microcontroller on the Wheatstone bridge circuit simulation of temperature measurement, it can better demonstrate the whole process of the experiment and introduces the principle, has certain help to the college physics teaching circuit.
