对测量重力加速度实验装置的改进

Improving the measurement device of gravity acceleration

在当前自由落体测量重力加速度实验基础上,增设光路指示灯、改造铅垂线,确保实验支架铅垂度.利用设计的输入接口电路、单片机电路、输出接口电路和电磁铁控制电路进行取样、处理和发送实验数据,提高时间测量精度.开发了测量重力加速度实验专用软件,实现了自动计算、保存和显示实验数据,避免手工计算、提高实验效率.改进后的自由落体测量重力加速度实验装置,简化了实验过程、减小了实验误差.

Based on the experiment free falling acceleration, the verticality of the bracket was ensured by adding optical indicators and improving the plumb line. To improve the accuracy of the experiment, input interface eircuit, mieroeontroller circuit, output interface circuit and control circuit of electromagnet were used in sampling, processing and transmitting the experimental data. Measurement software was designed to realize automatic calculation, storage and display of experimental data to improve the experimental efficieney. These improvements on the free fall acceleration device could simplify the experimental process and reduce experimental error.
