AUTOMATIC VOICE-GUIDING SYSTEM FOR EMERGENCY EVACUATION

摘要

PURPOSE: An automatic voice induction system for emergency evacuation is provided to control playback time in each of multiple speakers, thereby indicating a direction by generating sound. CONSTITUTION: An automatic voice induction system for emergency evacuation includes an acoustic signal transmission apparatus(100), a series transmission board(200), and a speaker(300). The series transmission board receives an acoustic signal transmitted from the acoustic signal transmission apparatus. The speaker plays the acoustic signal transmitted through the series transmission board. The acoustic signal transmission apparatus transmits the acoustic signal to be played in the speaker. The acoustic signal transmission apparatus comprises an analog/digital converter(120) and a channel encoding module(140). The series transmission board transmits the acoustic signal received in the acoustic signal transmission apparatus to the speaker.
