摘　　要：智能型重力加速度测试仪,是在原单摆实验装置的基础上,采用单片机和红外光电传感器实现对摆球的检测和控制,进而实现自动释放摆球、自动计数、自动计时、同时将检测信号进行自动处理,算出重力加速度。使传统单摆测量重力加速度的方法得到了较大的改进,提高了测量精度。The proposed intelligent instrument for acceleration of gravity is based on the original simple pendulum experiment device. It uses SCM and infrared photoelectric sensor to monitor and control the ball. It is capable of automatically releasing ball, timing, counting, and processing the detected signals to calculate acceleration of gravity. The method of measuring the acceleration of gravity and the measurement accuracy are significantly improved compared with traditional simple pendulum method.
