Abstract

Disclosed are a public address apparatus and time synchronization method using time-triggered CAN communication and a public address apparatus and time synchronization method using time-triggered CAN communication, for synchronizing time between a master node (1000) and a slave node (2100, 2200). The public address apparatus includes first node unit configured to transmit a public address signal including a sound source signal, a voice signal and a media signal, and a control signal according to a communication protocol, a second node unit configured to receive a public address signal and control signal from a main controller (100) and to perform control so that a public address signal is output, and a time synchronization unit configured to synchronize times of the first node unit and the second node unit so that the first node unit and the second node unit transmit the public address signal according to time-triggered CAN communication.
