符合多主多從之自動導航輪椅與遠端監控系統

Abstract

電動輪椅是老年人與身心殘障人士重要的行動輔具之一，但常因為人為操作疏失而造成意外的發生，如果能夠發展出一套自動導航系統，將可以降低人為操作的不當及看護等人力資源的浪費，此外，在電動輪椅裝置日益增加的情況下，若能透過一套共同的介面規範來將這些裝置整合在一起，不但能降低系統的複雜性，更可對於電動輪椅操控的安全性與便利性有所提升。 本研究的目標是要發展出一套符合M3S規範的自動輪椅導航系統，此套導航系統利用全球定位系統(GPS)與電子羅盤來做定位與定向，只要輪椅使用者在本論文所開發的電子地圖中輸入所欲前往的目的地後，這套導航系統便會自動地驅駛輪椅開往該地，相信藉由此系統的開發，將可替身心障礙者帶來許多便利，尤其是在特定的場所中(如機場、學校)，更能發揮此套系統的效果。 此外，為了提升該自動輪椅導航系統的安全性，本系統採用國際電動輪椅標準規範 — M3S系統 — 做為本系統的運作核心，在此架構的運作下，電動輪椅上各項裝置的整合將會更加便利與安全。最後，再加上遠端監控系統，透過無遠弗界的網路，讓在遠端的醫護人員或相關人士都可透過網頁瀏覽器，隨時監控電動輪椅的位置與使用者的生理狀態。

Power wheelchair is an important mobility aided for the elder and the disabled persons. However, accident may happen due to personal mistakes. If there is an auto-navigating system, mistaken manipulation and the waste of nursing will be decreased. Besides, the devices of power wheelchair are getting more diversified so a common interface to integrate these devices together is necessary. The purpose of this study is to develop a M3S-Based GPS navigation system for power wheelchair. The wheelchair steered with GPS and electronic compass can move automatically toward a specific destination through a GIS-Map in the computer. The topic of this study is to help people with disabilities regain independence of transportation in specific areas of their daily activities. This system is now designed to operate in special locations, for example, campuses or airports. Safety of the system is enhanced according to “M3S”, which is an international standard for power wheelchair. In the proposed architecture, modules are easily and securely integrated to the wheelchair. These include a tele-monitoring system implemented with computer network, mobile-phone and physiological sensors. Bio-signals, wheelchair location and other information of the user can be obtained by the nursing staff or any other medical personnel through using this system.
