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。
Experiment innovativeness research is a very important direction of college physics experimental research where the digital reconstruction of experimental equipment and tools is a distinctive direction. The key of the digitization is that how to convert the physic value to voltage or current signal.Based on the perspective of experiment equipment digitization,using many technique of electronic design. At first,transform the value of the physic quantity to electric signal by sensor,such as resistance sensor,ultrasonic wave sensor and hall sensor. Then using the conditioning circuit amplifying and shaping the signal. At last,signal digitized in MCU and processed signal display in LED or LCD.
