摘要

本研究旨在設計與製作掌上型藍芽無線傳輸點字顯示器之控制系統；系統概由數位控制機板、點字顯示方控制機板與點字顯示方三大模組整合而成。數位控制機板包含傳輸介面、微控制器、邏輯IC組與功能鍵。點字傳輸訊號經由藍芽與USB所組成之傳輸介面所接收；接而由微控制器與邏輯IC將訊號傳送至後端的點字顯示方；點字顯示時可使用功能鍵進行顯示功能控制。點字顯示方控制機板為連接數位控制機板與點字顯示方的橋樑；它可依顯示方的樣式而變更設計。本研究點字顯示方採壓電薄樑為驅動元件以提升顯示器的攜帶性。整體控制系統經電腦端藍芽無線傳輸器與測試程式驗證確可正確傳輸點字訊息。

The object of this study is to accomplish the control system design and implementation for Braille pod with Bluetooth interface. The system includes the digital control system board, the Braille display cells board and Braille display cells. The digital control system board integrates transmission interface, microcontroller, logic IC and function key. The transmission interface which is designed to transmit Braille signals, has both Bluetooth and USB interfaces. Then, the signals are transmitted through the microcontroller and logic ICs to Braille display cells. Besides that the function keys are used to control the display of Braille display cells. The Braille display cells board is the connection between the digital control system board and Braille display cells. It can be redesigned with different Braille display cells. The piezoelectric beams are used to drive the Braille display cells and make the Braille pod be carried easily. At the end, the control system is validated that the Braille signals can be transmitted through the Bluetooth dongle to the Braille pod accurately.
