发布时间:2019-07-27 09:47
【摘要】:大学物理创新性实验研究是实验研究的重要方面,而实验设备和工具的电化改造是其中的一个特色方向。数字化的关键是把被测物理量转换为电压或电流信号,从实验的数字化角度出发,介绍了大学物理实验中拓展性和创新性实验的设计方法。首先选择电阻传感器、超声波传感器、霍尔传感器将被测量转换成电量,然后通过调理电路对其进行放大和整形,最后使用电子设计的方法将信号取回微控制器,信号处理结果送入数码管和LCD液晶显示器等器件进行显示。
[Abstract]:Innovative experimental research in college physics is an important aspect of experimental research, and the electrification of experimental equipment and tools is one of the characteristic directions. The key of digitization is to convert the measured physical quantity into voltage or current signal. From the point of view of digitization of the experiment, the design method of expansibility and innovative experiment in university physics experiment is introduced. Firstly, resistance sensor, ultrasonic sensor and Hall sensor are selected to convert the measurement into electric quantity, and then the signal is amplified and reshaped by conditioning circuit. Finally, the signal is recovered by electronic design method, and the signal processing results are sent to digital tube and LCD liquid crystal display for display.
