摘　　要：传统的圆规通常采用人字形结构,先通过直尺量取的方式来确定画圆的半径,进而通过改变角度来实现画圆,二次量取和旋转圆规脚都会增大数据的误差,且给使用者带来诸多不便。本研究经深入调研和实践,在传统的圆规基础上进行创新,通过红外线传感测距来取代传统圆规通过直尺量取直径的方式,并采用滑动式改变直径,消除了传统圆规因频繁变化角度导致齿轮啮合不可靠的因素,在此基础上通过LED显示屏可视化读取半径值,且精度到小数点后三位。本研究的设计和制作具有创新型,将加快学生圆规制图速度,确保绘图的准确性,大大提高绘图的便利性与舒适性,具有重要的使用价值和推广价值。The traditional compass usually adopts herringbone structure.First,the radius of drawing a circle is determined by taking a ruler,and then the circle is drawn by changing the Angle.The quadratic measurement and rotating the compass foot will increase the error of the data and bring a lot of inconvenience to the user.After in-depth investigation and practice,this research is innovated on the basis of traditional compasses.It uses infrared sensor to replace the traditional compasses to measure the diameter through a ruler.At the same time,the diameter is changed by a sliding,which eliminates the unreliable factor of gear meshing caused by frequent angle changes of traditional compasses.On this basis,the radius value is visually read through the LED display,and the accuracy is to three decimal places.The design and production of this study is innovative,which will accelerate the drawing speed of students’compasses,ensure the accuracy of drawing,greatly improve the convenience and comfort of drawing,and have important use value and promotion value.
