本論文的設計概念是採用系統晶片實現智慧型控制的方式，以極簡型式設計「病床紅外線防跌語音警示系統」，此架構具有體積小、外型輕巧、架設快速、使用容易等特色，方便第一線醫護人員防止特定住院病患任意離開病床或病患不小心跌下床時，除了可使用語音提醒病患請勿隨意離開病床外，同時會發出警示聲響提醒醫護人員前來處理；而本文所採用之智慧型控制與檢測法則可避免其他光源的干擾；此外，住院病患在床上正常活動下，如坐起、躺下、翻身、移動等，也不會引起系統誤動作，如果病患意圖離開病床或病患不小心跌下床時，「病床紅外線防跌語音警示系統」就會發出警告聲響。另外，本文採用智慧型控制與檢測法則，所以能夠避免系統誤動作，可減低對住院病患的干擾，同時降低醫護人員的工作負擔。

關鍵字：紅外線、防跌、智慧型控制、檢測法則

The design concept of this thesis is to achieve the intelligent control of An Infrared Falling-Prevent Warning System with Voice Alert for Hospital Bed by using a system-on-chip. This structure is small, compact in size and lightweight, fast to react, and easy to use. It can help front-line medical personnel to prevent specific inpatient out of bed intentionally or accidentally. In addition to use voice alert to remind patients do not get out of bed, at the same time the system will issue a alarm sound to remind health care workers to handle the case. By using intelligent control and detection algorithm, this method can avoid disturbances from other light sources. In addition, normal activities such as sitting up, lying down, standing up, movement for the hospitalized patients in bed, will not cause system to malfunction. If a patient attempt to get out of bed or accidentally fell out of bed, this infrared falling-prevent warning system can issue a alarm sound with voice alert. This infrared falling-prevent warning system with intelligent control and detection rules can avoid system malfunction, thus, reduce the unnecessary interference for the hospitalized patients and lessen the work loading of medical staff.

Keywords: infrared、fall prevention、intelligent control、detection rules
