Abstract

The utility model provides a portable intelligent fall-down detector which is used for detecting fall-down of the olds. By detecting the change of severe acceleration along with the change of human body positions, the portable intelligent fall-down detector obtains a real-time signal and transmits the real-time signal to an information processing center to perform storage and analysis, so that whether fall-down happens can be determined. If the fall-down happens, the detector firstly performs local 10-second audible and visual alarm. If a key for canceling the alarm is not input within ten seconds of the audible and visual alarm, after the audible and visual alarm, the detector automatically sends an alarm short message to a mobile phone of an assigned guardian through general packet radio service (GPRS) and simultaneously sends alarm information to an intelligent household remote control monitoring homepage and a mobile phone to perform alarm prompt through wireless Zigbee. The portable intelligent fall-down detector can further actively trigger an alarm key to seek help under other emergency situations.
