摘要

摘 要
本論文研製出一套隨插隨用耗電量低的無線傳輸人體單點動態訊號之核心系統，該系統可以適用於量測人體單點位置的X座標與Y座標的絕對向量與Z座標的相對向量，並使用無線技術傳輸經由USB介面記錄於個人電腦平台，且具有以下優點:高解析度與低耗電量，體積小重量輕且無需接線使得容易貼附人體並符合ISM規範，以及支援大量資料儲存的系統。
此系統包含發送端裝置;發送端微處理器;接收端裝置與接收端USB微處理器;以及電腦應用介面。人體的單點動態生理訊號可以經由發送端模組以無線傳輸通訊協定傳送到接收模組處理，經由USB介面傳送到電腦主機做儲存與記錄。無線傳輸的方式提供方便且不受限制的生理訊號監控模式，USB介面提供高速與隨插隨用的電腦通訊方式改變了以往低速的電腦介面。
系統經測試的結果，RF無線收發器在十公尺的範圍內可以提供 38.4K bps的傳輸速率，有障礙物的情況也能提供至少14.4K bps的傳輸率，動態訊號能穩定的傳送到電腦，接收端隨插隨用的特性使得一般人也可操作此系統。

Abstract
Develop a wireless system to transmit human body motion signal and have low power consumption，plug and play characteristic. It can suit to measure the X axis; Y axis absolute vectors and Z axis relative vector of single point on the human body motion by RF transceiver , recording data and saving in the Personal Computer through Universal Serial Bus( USB ) in order to have a high resolution, low power consumption, light weight and small size to attached human body easily.
This system includes front-side wireless transceiver unit, back-side wireless transceiver unit, USB mid-interface unit and computer user interface. Three axis sensor capture the human body motion signal and pass in the microcontroller which is driver the wireless device to transmit data to the back-side, and the back-side microcontroller receiver data make a check and feedback a acknowledge. USB interface unit will transmit the data to the computer user interface software at the same time; this system has been completed recording human body motion date with wireless.
In no barrier equipment, this system can provide 38.4K bps transmit speed around ten meter range, even has a barrier that’s still can provide 14.4K bps in stable transmit speed. Actually people can operate the system very easy by the plug and play characteristic.
