Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a master station 1 provided in a local government in a fixed system of a disaster prevention administrative radio system, and an outdoor loudspeaker 2 connected to the master station 1 by a wireless line and installed in a plurality of outdoor child stations. One of them is shown,
Illustration of other outdoor loudspeakers is omitted.

The outdoor loudspeaker 2 includes a transmission / reception unit 3 for transmitting information to a master station via a wireless line, an external speaker 4 for performing outdoor loudspeaker broadcasting, a monitor speaker 5 for confirming broadcast contents, and an outdoor loudspeaker. An operation unit 6 for an operator of the loudspeaker 2 to perform an operation input; a microphone 7 for inputting broadcast content; an overwriting memory 8 for storing the input broadcast content by an overwriting method; The system includes a registration memory 9 for registering broadcast contents transmitted from the station 1 and a control unit 10 for controlling the above-described units.

Next, the operation will be described with reference to FIGS. FIG. 2 is a flowchart showing a procedure for processing a local station broadcast in the outdoor publicity method of the emergency radio system according to the present invention. In the case of the own station broadcast mode in which the own station broadcast is performed in the outdoor slave station, first, the control unit 10 receives an instruction signal input from the operation unit 6 by the operator (Step 1; S1),
It is determined whether or not it is in its own station broadcast mode (S2). As a result of the determination, in the case of the own station broadcast mode, the broadcast content to be continuously received is stored in the overwrite memory 8 (S3).

Next, a play button (not shown) on the operation unit 6
Is pressed, the control unit 10 detects this and outputs the broadcast content stored in the overwrite memory 8 to the monitor speaker 5,
The operator is made to check in advance whether there is any error in the broadcast contents (S4).

As a result of the monitoring, the control unit 10 detects a signal indicating a loudspeaker broadcasting instruction by a recording / playback button (not shown) input from the operation unit 6 when there is no error in the broadcast contents (S5). The contents stored in the writing memory 8 are broadcast through the external speaker 4 (S6).
