    Abstract: 電流尺的概念來自於右手定則—導線上的電流產生環狀磁場,利用這種電流尺電路以S形走線,排列成電流尺的線路,量測其所產生的磁場分佈做線性編碼,特性類似磁性尺,卻擁有更佳的性能與精度。本論文內容主要設計一個電流尺的量測實驗平台,使用新一代GMR作磁場量測,以UDS系統作為開發主軸。驅動裝置方面設計使用線性馬達機台,並以光學尺提供一組精度達5 的線性位移參考數據。電路方面由DSP主控,配合週邊類比數位轉換、FPGA設計、磁場量測等電路,成為電流尺系統實驗平台,發展以低成本、高精度的新一代線性尺,並針對電流尺所產生的波形模擬、分析、量測與討論,提供日後進一步發展電流尺編碼參考。 The new type of Linear Encoder. The new encoder decrease the disadvantage of other linear encoder. We use new sensor to sense the magnetic field which is generated by PCB. This paper research the wave form of Electrical Linear Encoder. Hope to find the most fit of PCB and MR sensors to get the best signal to encode.
