As such, step S500 displays in real time at least one or more of the status information of the plurality of field control devices 400 output diagnosis information, list inquiry, and waveform information obtained by converting the on-site broadcasting sound signal into a waveform.

At this time, the display in the waveform is a function of displaying the audio data received from the field broadcasting area module 200 as a waveform so that the operator of the central center module 100 can visually check the site sound state that is currently remote warning broadcast. Do this.

10 is a flowchart illustrating a method of receiving output diagnostic information according to FIG. 9.

Referring to FIG. 10, a field broadcasting area module connected to a field control device 400 while simultaneously inputting a field broadcasting sound to the field control input unit 440 of the field broadcasting device 400 included in the field broadcasting area module 300. The output diagnosis unit 500 included in 300 requests the measurement value of the field control output unit 420 (S10).

Next, on-site control output by comparing the reference value (W) by the wattmeter method through the on-site control measuring unit 460 based on the measured value of the on-site control output unit 420 received by the output diagnostic unit 500 The measured value of the unit 420 is diagnosed to calculate a result value of the output diagnosis information (S20).

Next, the result value diagnosed by the field control measurement unit 460 is displayed through the field control display unit 470 (S30).

Next, the result value is transmitted to the remote broadcasting device 200 (S40).

Although a preferred embodiment according to the present invention has been described above, it is possible to modify in various forms, and those skilled in the art to various modifications and modifications without departing from the claims of the present invention It is understood that it may be practiced.
