You can give priority. When any one standby standby device among the plurality of standby broadcast devices 120 replaces the active broadcast device 110, the standby broadcast device replacing the active broadcast device 110 performs local broadcasts and central broadcasts that were previously in charge. All must be done. Therefore, the main control unit 130 has an advantage in that it is possible to select a standby broadcast device capable of focusing on outputting the central broadcast rather than the local broadcast by selecting the local broadcast output frequency as a reference.

In another embodiment, when the main control unit 130 has an abnormality in the active broadcasting device 110, one standby broadcasting device 120 is randomly selected for the N standby broadcasting devices 120-1 to 120-N. ) To control to perform the role of the active broadcasting device 110. However, the present invention is not limited thereto, and any method of selecting any one of the plurality of standby broadcast devices 120 may be applied.

Thereafter, the main control unit 130 may diagnose the state of the standby broadcast device 120-1 of the first priority selected in step S130 (S140). For example, the main control unit 130 confirms whether the standby communication device 120-1 of the first priority performs network communication or transmits/receives data, that is, the state of the active broadcasting device 110. Through the same method as the method for diagnosing, it is possible to diagnose the state of the standby broadcast device 120-1 of the first priority.

Here, as a result of the diagnosis by the main control unit 130, when the status of the standby broadcasting device 120-1 of the first priority is settled, the main control unit 130 serves as the active broadcasting device 110 as the first priority. By transferring to the standby broadcasting apparatus 120-1 of the, it is possible to control the standby broadcasting apparatus 120-1 of the first priority to output a broadcast to the entire broadcasting zone.

If, in step S150, the status of the first priority standby broadcast device 120-1 is diagnosed as an abnormal state, the main control unit 130 based on the priority, the standby broadcast device of the second priority ( 120-2) to the N-th priority standby broadcasting device 120-N may be sequentially selected, and the status of the selected standby broadcasting device may be diagnosed.
