摘要
本作品是电磁控制运动装置。此装置包括电磁控制装置、摆杆、单片机、声光报警、液晶显示器、键盘、角度传感器等,利用STC12C5A60S2单片机,通过线圈驱动电路对小型磁感线圈进行通电,使得单摆在磁场作用下摆动,来达到实现题目的要求。在设计此作品时,我们的独特之处就是采用角度传感器,能够测量出高精度的旋转角度,通过单片机内部AD转换器,转变成数字量进行识别,线圈采用LM298作为驱动器。
The electromagnetic control device consists of electromagnetic control unit,pendulum rod,SCM,sound and light alarm unit,LED screen,keyboard,and anglar sensors.Single pendulum is driven to swing in a magnetic field through coil driving circuitry inducing miniature magnetic induction loop,which is driven by LM298,to generate electricity.The device is characterized by the use of angular sensors,which is capable of measuring the exact angle of rotation.Then the data is converted into digital code through the AD converter within the SCM.
