平面或曲面曲线长度测量仪的设计实现

以单片机为核心，采用光电传感技术，加之适当设计的机械传动装置，将曲线上的位移转换为脉冲；使用电池供电，设计制作了便携、滚轮式曲线测量仪，推动滚轮沿曲线运动，显示器显示测量的结果。该测量仪适用于服装设计、打板过程中对袖隆、领口等部位进行曲线长度的测量。经服装厂实际使用，完全能够满足使用要求，可以取代进口弯尺。同时，此测量仪也可以推广应用到其他领域各种曲线的长度测量。

Design and Realization of the Length Gauge of Curves of Plane or Curved Surface

With single chip computer as the core, and by using photoelectric sensing technology and properly designed mechanical transmission device, the portable rolling wheel type length gauge of curves is developed. The instrument is powered by batteries and converts the displacement on curves into pulses. The measuring results are displayed on monitor when rolling wheel being impelled along the curve. The instrument is suitable for clothing measurement, e.g. measuring the length of curves for sleeves arm hole and collar bands. Through the practical application in garment factories ,it replaces the imported crooked - ruler and satisfies the operational requirements. The gauge can be also used for length measurement of various curves in other areas.
