SELF-CONTAINED DETECTION METHOD AND DEVICE |
摘要 |
The detection device comprises a sensor, a power supply, an alarm and an acousto-electric transducer. The activated acousto-electric transducer receives an acoustic signal and emits an electrical signal representative of the acoustic signal. The detection device further comprises a means of recognizing a predefined acoustic signal according to the electrical signal emitted by the transducer and triggering an emission of a message by the alarm when the predefined acoustic signal is recognized. The acoustic-electric transducer is only activated at regular intervals. Preferably, the transducer also serves an alarm to emit the message when the predefined acoustic signal is recognized. |
