AUTOMATIC FALLING DETECTION AND ALERT SYSTEM

摘要

An automatic falling detection and alert system is provided to grasp the situation of a field by providing a bidirectional sound communication function. An acceleration sensor(104) monitors the falling in real time. A wireless alarm transmitting device transmits the falling by a wireless communication network. An automatic falling detection and alert system includes an emergency button(111), a cancel button(112), a voice encoder(103), and a voice decoder(105). A DTMF(Dual Tone Multi Frequency) generator performs the connection with a previously stored phone number. The voice encoder and the voice decoder support the two-way voice communication. The voice is stored to transmit the previously stored voice message to the voice recording chip.
