新型手持式智能曲面尺的设计

Design ofa hand-held smart curved ruler

文中介绍了一款基于TI CC2540的手持式智能曲面尺的设计。该尺通过记录精密滚轮在物体表面滚动的距离,实现长距离不间断测量。设计采用自制的磁电编码组件,利用径向充磁的柱状磁铁作为转轴,将磁电编码器AS5145B和滚轮合二为一,并利用TP4056充电模块实现充电功能,采用OLED屏幕进行显示,结合软件设计,实现了测量数据的读取、存储和显示。

A hand-held smart ruler based on TI CC2540 is introduced in this paper. By measuring the rolling distance of an idler wheel on the surface of the irregular objects, the long distance and uninterrupted measurement can be achieved. The design uses the self-made magnetoelectric coding component, uses the radial magnetized columnar magnet as the rotating shaft, combines the magnetoelectric encoder AS5145 B and the roller into one,uses the TP4056 charging module to realize the charging function,and uses the OLED screen for display. Combined with the software design,this smart ruler can achieve measurement,data storage and display.
