Smart band for autonumously recognizing crisis situation and automatically requesting rescue on the basis of sound and motion patterns

摘要

Disclosed is a wearable device for sensing a crisis situation and requesting rescue. The smart band has: a microphone for collecting sound patterns emitted in a crisis situation; a sound/speech signal pattern library for storing keyword sound patterns generated in each crisis situation; sensors installed to sense abrupt movement of a wearer; a motion analysis memory for storing a waveform determination algorithm for collecting signals inputted from the sensors, analyzing a motion signal pattern, and categorizing the motion signal pattern as impulse, pulsation or steady; a crisis situation recognition processor for deriving a crisis situation code; a microcontroller for automatically transmitting a request for rescue, together with the crisis situation code, GPS position and personal information of the wearer; a Bluetooth communication interface unit; a smart phone monitoring circuit; and a switch for recording sexual harassment speeches or manually initiating a crisis situation when the wearer is sexually harassed.
