Description

An alarm system capable of broadcasting immediately upon receiving a disaster and civil defense alert, a terminal device used thereto, and an operation method {A system and method for broadcasting civil alerts in real-time and the terminal apparatus used thereto}

The present invention relates to a warning system capable of broadcasting immediately upon receiving a disaster and civil defense warning, and to a terminal device used therein. In particular, the disaster and civil defense warning (hereinafter used in this specification as a concept including 'civil and public warning') It relates to an alarm system and a terminal used therein that enable immediate broadcasting by temporarily broadcasting only priority broadcasting speakers, skipping the normal public address system, as a separate alarm terminal device upon reception.

In addition, a method of operating an alarm system that enables immediate broadcasting is provided.

A public address system centrally controls voice information such as music, announcements, and emergency broadcasts in large buildings such as schools, apartments, department stores, shopping malls, and office buildings, or in large areas such as amusement parks, ski resorts, and sports stadiums. It is a broadcasting system that can be transmitted by simple operation of the equipment. It normally makes music or announcements, but when a disaster such as an earthquake, tsunami, or fire occurs, or during civil defense training, disaster and disaster warnings are broadcast according to a designated program or central control device. Civil defense broadcasts or emergency broadcasts are made.

As technology related to the public address system that also serves as emergency broadcasting, Republic of Korea Patent No. 0420165 (name: Public address management system) (first prior art) and Korea Patent No. 1605661 (name: speaker switch added to the public address system and Controller) (second prior art) is disclosed.

However, in the first and second conventional technologies, the public address management system or central control equipment performs both general broadcasting and emergency broadcasting, so it is not easy to respond immediately in an emergency. Conversely, in order to respond immediately, the entire system must wait. Therefore, there was a problem that it was uneconomical.

Meanwhile, it is a technology related to a public address-compatible audio mixer that effectively delivers emergency broadcasts (evacuation broadcasts) to personnel in a building by incorporating a broadcast congestion function through emergency contact input, Republic of Korea Patent No. 2245197 (name: Emergency contact input) A public address-compatible audio mixer with a broadcast congestion function has been disclosed, and this will be described as a third prior art with reference to FIGS. 1 and 2.

As shown in FIG. 1, the public address-compatible audio mixer according to the third prior art has a function of receiving an emergency contact input to the audio mixer 100 and a function of staging mixed audio output. In the third prior art, the control signal transmission/reception interface between the public address equipment 20 and the audio mixer 100 is configured as a dry contact.

First, the audio mixer 100 checks the emergency contact input provided from the public address equipment 20, and if the emergency contact point is in the ON state as a result of the confirmation, this means that the public address equipment 20 is broadcasting emergency information in the building due to a fire, etc. This means that the audio mixer 100 activates the emergency output control signal to make an emergency announcement broadcast, and sets the ON/OFF control circuit of the mixer output to OFF to provide general broadcast output. Stop it.

Through this, general broadcasting, such as in-house music broadcasting or radio broadcasting, is stopped in an emergency, and only emergency information broadcasting is output through speakers in the building.

Next, the audio mixer 100 rechecks the emergency contact input provided from the public address equipment 20, and if the emergency contact point is in the OFF state, this means that the public address equipment 20 is no longer broadcasting emergency information. Since this means that it is in a state, in response, the audio mixer 100 deactivates the emergency output control signal to return to the normal state and sets the ON/OFF control circuit of the mixer output to ON to resume normal broadcasting output.

Referring to FIG. 2, the audio mixer 100 according to the third prior art includes a multiple audio input unit 110, an audio mixing processor 120, a multiple audio output unit 130, an audio status display unit 140, and an emergency detection unit. It is comprised of a contact input unit 150, an emergency detection detection circuit unit 160, and an emergency response blocking control unit 170.

First, the multiple audio input unit 110 is a configuration that receives a plurality of analog or digital audio inputs from the outside.

The audio mixing processing unit 120 is a component that performs analog or digital audio mixing processing on a plurality of audio inputs provided through the multiple audio input unit 110 in response to user manipulation of the audio mixer 100.

The multi-audio output unit 130 is configured to externally output audio signals on which analog or digital audio mixing processing has been performed by the audio mixing processor 120 in analog or digital form.

The audio status display unit 140 is configured to output and display the audio input/output status of the audio mixer 100 through a user display of the audio mixer 100, for example, a level meter. To this end, the audio status display unit 140 receives audio input status information from the multiple audio input unit 110 and audio output status information from the multiple audio output unit 130. In the third prior art, there may be a case where the mixed audio output is blocked in response to an emergency contact input, but it is desirable that the audio status display unit 140 displays normally even during this time. This is because music broadcasts or radio broadcasts are transmitted through speakers. Although it is not output, this is to confirm to the operator that the audio mixer 100 is operating normally.

The emergency detection contact input unit 150 is configured to receive a control signal from the external public address equipment 20 through a non-voltage contact point, and the emergency detection detection circuit unit 160 receives a control signal provided from the emergency detection contact input unit 150. This is a configuration that detects an emergency detection signal from.

The emergency response blocking control unit 170 is configured to control the external output of the audio signal through the multiple audio output unit 130 in response to whether an emergency detection signal is detected by the emergency detection detection circuit unit 160.

Figure 2 shows a configuration in which the emergency response blocking control unit 170 controls blocking the external output of an audio signal in the third prior art. Referring to FIG. 2, the audio mixing processing unit 120 is connected to perform audio mixing processing on a plurality of audio inputs and directly provide the results to the multiple audio output unit 130. At this time, the emergency response blocking control unit 170 outputs the audio mixing processing unit 120 to the multiple audio output unit 130 in response to whether or not the emergency detection signal is detected by the emergency detection detection circuit unit 160. Block and control to prevent it from happening. Components related to audio processing of the audio mixer 100 originally use high-quality elements, so according to the embodiment of FIG. 2, the high sound quality of SR broadcasting can be maintained without a significant increase in price.

However, according to the third prior art, it is assumed that all broadcasting systems, including the audio mixer 100, must operate 24 hours a day. If, in Figure 2, the audio mixing processing unit 120, etc. is in a deactivated state, there is no mention of how to respond when an emergency detection signal is received. Even if some functions are alive, the emergency detection signal is sensed and the entire Even when configured to wake up, there is a limitation in that it takes a considerable amount of time to wake up the entire broadcasting system.

Meanwhile, as a technology related to a disaster warning broadcasting system, Republic of Korea Patent No. 2278793 (name: multiple disaster warning broadcasting system with program controller for multiple emergency broadcasting) (fourth prior art) is disclosed, Figures 3 to 5 With reference to , this is explained as the fourth prior art.

The multi-disaster warning broadcasting system equipped with a multi-emergency broadcasting program controller according to the fourth prior art includes a multi-emergency broadcasting program controller (MEPC; Multi Emergency Broadcasting Program Controller) 100 and a multi-emergency broadcasting audio controller (MEAC; Multi Emergency It consists of a Broadcasting Audio Controller (200) and a central control unit (CPU) (300).

The multiple disaster warning broadcasting system equipped with a program controller for multiple emergency broadcasting of the fourth prior art is intended to transmit disaster warning emergency broadcasting in the event of a disaster, and can be configured as a part of the overall broadcasting system that performs general broadcasting such as announcement broadcasting. It is configured to use the output amplifier and speaker together for disaster emergency broadcasting and general broadcasting.

The multiple emergency broadcasting program controller (MEPC) 100 and the multiple emergency broadcasting audio controller (MEAC) 200, which are components of the fourth prior art, do not operate during general broadcasting, and voice or sound data for general broadcasting is not part of MEAC. Bypassing the configuration, it can be operated to broadcast through the output amplifier and speakers.

When a disaster signal is input, the multi-emergency broadcasting program controller 100 provided in the fourth prior art controls the device so that the broadcasting system of the fourth prior art transmits a disaster warning broadcast.

The central control unit (CPU) 300 provided in the fourth prior art prioritizes disaster recovery regardless of what state the system is in, that is, regardless of whether the system is in a standby state or a general broadcasting state. The system is controlled so that emergency broadcasts for warnings are transmitted. In particular, if a disaster signal is input while a general broadcast is being transmitted, the broadcasting system is activated (WakeUp) and controlled so that a disaster warning broadcast can be transmitted immediately.

The MEPC (100) receives disaster signals through one or multiple input channels and supplies the signals to the system. The MEPC of the fourth prior art is equipped with a plurality of input channels (configured to correspond 1:1 to the input terminals) that supply disaster signals input through a plurality of input terminals (provided on the rear) into the interior of the system. there is. The input channel of the fourth prior art is a physically constructed disaster signal input path and includes an input terminal, a communication line, and a disaster display unit.

The broadcasting system of the fourth prior art can configure the contents of emergency broadcasts to be transmitted differently depending on the type of input disaster. In other words, the content of the emergency broadcast message transmitted can be set to be different depending on the type and location of the disaster input through the input channel.

The audio controller 200 for multi-emergency broadcasting is a means for controlling the input and output of broadcast comments and sound data for disaster warning emergency broadcasting in the fourth prior art broadcasting system. The MEAC (200) controls the operation of each component through the MCU (201) provided therein.

The MEAC (200) of the fourth prior art includes a MIC input unit (211) through which a voice signal is input through a microphone as a sound source input means, and an MP3 module (212) where broadcast comments and/or sound data to be output are stored in the form of an MP3 file. ) is provided, and an external sound source input unit 213 is provided through which sound signals output from an external audio device, etc. are input. The MP3 module 212 stores sound source data (data including comments and sounds for warning broadcasting) selected according to the content of the disaster broadcast, and the microphone switch 203 allows the administrator to voice the disaster warning emergency broadcast in an emergency situation. It is intended to carry out. The MCU (201), which is a control means of the MEAC (200), sends alarm sound source data selected from files stored in the MP3 module (212) and broadcast comments input through the microphone switch (203) to the output amplifier (221) and the speaker. Control the system so that it is transmitted through (222).

The test switch (205; TEST SW) is a means for testing whether the broadcasting system of the fourth prior art operates normally. When this switch is pressed, voice comments, etc. input through the microphone 204 are transmitted through the output amplifier and speaker. It is a means to test whether it is transmitted correctly.

Meanwhile, when a disaster signal is input to the broadcasting system of the fourth prior art and a situation arises in which an emergency broadcast for disaster warning must be transmitted, the MEAC (200) stops transmitting general broadcasting and gives priority to emergency broadcasting for disaster warning. Operate the device to transmit. The operation for converting the broadcasting system of the fourth prior art to an emergency broadcasting state for disaster warning is performed under the control of the central control unit 300 (CPU), which will be described below.

In the fourth prior art, when a disaster signal is input through the input channel of the MEPC (100), the disaster signal is transmitted to the MEAC (200) and CPU (300) through RS485 communication. The MEAC 200 and CPU 300, which have received the disaster signal, control the device so that an emergency broadcast for disaster warning is transmitted through the output channel matched with the input channel according to the contents of the input disaster signal.

The output channel of the fourth prior art may be matched 1:1 with the input channel, or may be set so that a plurality of output channels are matched to one input channel.

The MEAC of the fourth prior art is equipped with an MP3 module 212 that stores broadcast contents for each disaster as digital sound data. Sound data for disaster warning broadcasting stored in MP3 coding can be selected and used among those stored in the MP3 module 212. The MP3 module 212 of the fourth prior art is equipped with a USB port, so sound data stored in an external device can be freely updated and used for disaster broadcasting.

When the device of the fourth prior art switches to the emergency broadcasting state for disaster warning, the MCU (201) of the MEAC (200) sends sound data to the MP3 module through an output channel determined according to the type or location of the input disaster. The selector is controlled to select at (212), and the sound data for disaster warning selected in this way is transmitted through the output amplifier 221 and speaker 222 included in the range of the corresponding channel.

However, the central control unit (CPU) according to the fourth prior art preferentially sends a disaster warning regardless of what state the system is in (i.e., regardless of whether the system is in a standby state or a general broadcasting state). The system is controlled so that emergency broadcasts are transmitted, but if a disaster signal is input while a general broadcast is being transmitted, the broadcasting system is activated (WakeUp) and controlled so that a disaster warning broadcast can be transmitted. Therefore, a delay of several seconds occurs, and even if the delay is only 3 to 10 seconds (mostly 5 to 9 seconds), it is a time that cannot be ignored in disaster warnings such as earthquake or tsunami warnings.

In addition, as mentioned above, if the broadcasting system is always turned on, it is possible to prevent a delay of several seconds required to wake up the disaster broadcasting system, but it is also reasonable to blindly turn on the disaster broadcasting system, which consumes a lot of power. is not

In other words, will both the first to fourth prior technologies tolerate a delay of several seconds required to activate (WakeUp) the disaster broadcasting system? We are at a crossroads as to whether to keep the expensive disaster broadcasting system active (WakeUp).

This is an example of the rear part of the terminal device used in the system.

When a disaster occurs, national agencies provide disaster information based on information obtained from disaster and civil defense detection equipment, and competent agencies such as the Ministry of Public Administration and Security issue disaster and civil defense warnings and provide disaster and civil defense information through broadcasting and media. It is designed to broadcast warnings (breaking news).

After the revision of the Framework Act on Civil Defense, the government has opened standard protocol sources for free through national projects and encouraged widespread use. In the future, the disaster and civil defense-related market has a strong public aspect, so continuous investment is expected to be made in relation to disaster and civil defense broadcasting. Accordingly, NFTC202 of the Fire Service Act stipulates that existing broadcasting systems must be broadcast within 10 seconds, taking into account the time limit required to start broadcasting. Previously, due to the time required to start such broadcasting, the broadcasting system had to be broadcast within 10 seconds after the seismic wave had passed and after the tsunami had struck. There was a problem that immediate broadcasting was not possible, such as , etc.

In order to solve this existing problem, in the present invention, as shown in FIG. 6, an alarm terminal device 200, which is connected to the alarm control system 100 and Ethernet, LTE, etc., and transmits an alarm, is connected to the existing public address system ( 300), when receiving a disaster or civil defense alert, priority broadcasting using the emergency broadcasting speaker (400) equipment begins without delay, and after the existing public address equipment (300) is activated (5 to 10 seconds later) ), the existing problem is solved by automatically switching to the existing public address system (300) to prevent delay in disaster-related broadcasting.

To achieve this, the following functions must be added to the entire alarm system, including the alarm terminal device 200 of FIG. 6.

1) As a disaster and civil defense warning terminal, it has the function of responding to the Ministry of Public Administration and Security's civil defense standard protocols.

2) A function that includes a contact point for controlling public address equipment or a serial communication unit to transmit warning information received from disaster and civil defense alarm terminals.

3) A function to immediately start disaster and civil defense broadcasting using the built-in power amplifier when an alarm is received.

4) When a disaster or civil defense alert is received, a function that switches the switch on the built-in terminal board to connect the speaker connected to the existing broadcasting system and the output of the built-in power amplifier.

5) A function that monitors the output signal of the amplifier of the existing public address system and immediately disconnects the built-in power amplifier by switching the switch so that it is not connected to the existing speaker when the amplifier output signal is input.

6) Alert display function that always monitors the line status of speakers designated for priority broadcasting and allows response when line problems occur

7) A function that monitors the current status and automatically switches to a normal line when a problem occurs to transmit broadcasts.

8) First, when connecting speakers for broadcasting, dualization is configured with primary and secondary speakers, and if a line problem occurs in the primary speaker, it is automatically switched to the secondary speaker to ensure that disaster and civil defense broadcasts are transmitted without any problems.

9) If the amplifier output of the public address equipment is not detected for more than a certain period of time, the alarm terminal device of the present invention continues broadcasting, displays a notification of abnormal conditions on the equipment itself, and does not switch to the existing public address equipment line. .

10) If the amplifier output of the public address equipment is not detected for more than a certain period of time, a function that sends a warning text message to the administrator about the abnormal condition using the built-in LTE module.

11) A function that enables quick initial evacuation by first driving only some speakers in the main broadcasting area through the built-in power amplifier.

In normal times, the public address controller 310 of the public address system 300 outputs general broadcasting signals such as music amplified through the amplifier 320 to the speaker 400, and even in the deactivated state, the emergency panel 340 ), when a start signal is received from the alarm terminal device 200, it wakes up and outputs the alarm broadcast sound source received from the alarm terminal device 200 to the speaker 400. Unexplained symbol 330 is a speaker controller.

However, when a disaster and civil defense alert is propagated from the government's alert control system 100 to the alert terminal device 200 via Ethernet, LTE, etc., it is received by the alert standard protocol receiver 240 of the alert terminal device 200, The external amplifier monitoring and speaker control unit 210 immediately switches the switch unit 270 so that the emergency broadcasting signal amplified through the power amplifier 220 is output to the priority broadcasting speakers 411, 421, and 431 in each area. Control. Accordingly, disaster and civil defense broadcasts can be broadcast through priority broadcasting speakers without any time delay.

At the same time, the external broadcasting equipment linked data processing unit 230 of the alarm terminal device 200 is used as an emergency panel 340 of the public address system 300 for wake-up of the public address system when an alarm is received. By outputting contact or serial communication data, the public address system 300 is wake-up and the sound source stored in the alarm information storage unit 250 is transmitted according to the received alarm standard protocol. And, all of these operating situations are displayed through the information display unit 260 of the alarm terminal device 200 so that the manager can easily understand the situation.

In some cases, if the output of the amplifier 320 of the public address system 300 is not detected even after a certain period of time, not only does a warning appear on the information display unit 260, but the manager can also use the built-in LTE module 280 to alert the manager to an abnormal condition. It is possible to send a warning text message. This is because the warning terminal device 200 has a limited temporary disaster and civil defense broadcasting function or a limited number of speakers, so disaster and civil defense broadcasting must continue to be made stably through the public address system 300 after a certain period of time.

More preferably, among the local speakers 410, 420, 430 of the emergency broadcasting speaker 400, not only one pair of priority broadcasting speakers is designated, but in addition to the first priority broadcasting speakers 411, 421, 431, 2 Additional speakers (not shown) for primary priority broadcasting are designated, but the speaker line is monitored and, in case the primary priority broadcasting speakers (411, 421, 431) are disabled, this is detected and transmitted through the secondary priority broadcasting speakers. It is a good idea to make emergency broadcasts available.

Now, the alarm terminal device 200 monitors the output signal of the amplifier 320 of the public address system, and when the amplifier output signal is input, it immediately switches the switch unit 270 so that it is not connected to the existing speaker to connect the built-in power amplifier. The connection must be separated.

The alarm terminal device 200 always monitors the line status of the broadcasting speakers 411, 421, and 431, and when a problem occurs on the line, displays a notification to enable response, and also provides the manager with the built-in LTE module 280. Use to send a warning text message about abnormal conditions.

As described above, the alarm terminal device 200 of the present invention must always be in a wake-up state, so it has no choice but to be configured with minimal resources in consideration of economic efficiency. It continuously monitors the current status and automatically switches to a normal line when a problem occurs. Switch to so that the broadcast is transmitted (preferably through the primary priority broadcasting speaker rather than the secondary priority broadcasting speaker, and through the amplifier 320 of the public address system rather than the power amplifier 220 of the alarm terminal device).

Therefore, if the amplifier output of the public address equipment 300 is not detected even after a certain period of time, the broadcast continues with the alarm terminal device 200 of the present invention, and a notification of the abnormal condition is displayed on the equipment itself, Broadcasting equipment must be restored.

In Figure 8, an example of the rear part of the alarm terminal device 200 of the present invention is shown, where reference number 201 is a DMB antenna connection end, reference number 202 is an LTE antenna connection end, and reference number ( 203) is the FM-Radio antenna connection terminal, (204) is the power input terminal, and (205) is the ground terminal.

In Figure 7, an example of the alarm control system 100 is schematically shown. The Ministry of Public Administration and Security server 101 is linked to the central first alarm control center server 110 and the central second alarm control center server 120, and is used for exclusive use. Through the information network 102, which is a line, the first disaster warning is issued to each city/provincial warning control center server 130, and each city/provincial warning control center server 130 is connected to the city/county warning control center server 140, A disaster warning is issued to the broadcasting company/major organization server 150 and the first alarm terminal device 200. In some cases, some of the second alarm terminal devices 200' may receive warnings from the city/county alarm control server 140.

Ultimately, according to the "alarm system capable of broadcasting immediately upon receiving a disaster and civil defense alert and a terminal device used therein" according to the present invention, upon receiving a disaster and civil defense alert, disaster and civil defense broadcasting is possible immediately through the priority broadcasting speaker without time delay. Then, when the public address system wakes up (after a few seconds) and broadcasting is possible, the switching is returned to the amplifier of the public address system. Therefore, it can be applied to the existing public address system even at a low cost.

(Method of operating an alarm system according to the optimal embodiment of the present invention)

Now, a method of operating an alarm system capable of broadcasting immediately upon receiving a disaster and civil defense warning according to an optimal embodiment of the present invention will be described in detail below, mainly referring to FIGS. 9 and 10 and auxiliary to FIG. 6.

Figure 9 is a conceptual diagram of the operation of the alarm terminal device of the alarm system according to the present invention, and Figure 10 is a flowchart of the operation of the alarm terminal device of the alarm system according to the present invention.

The method of operating the alarm system of the alarm system according to the present invention corresponds to the control operation of the terminal device, where the control unit: i) may be provided with a separate MCU, but ii) is implemented with the minimum number of elements. The external amplifier monitoring and speaker control unit 210 may replace it, or iii) an additional control unit that includes the external amplifier monitoring and speaker control unit 210 and controls the overall operation of the terminal device may be configured. This embodiment will also be described based on the iii)th case above.

First, the control unit 210 of the alarm terminal device 200 asks, has the alarm standard protocol receiver 240 received the disaster and civil defense warning? It is checked (S1), and if not received, it is continuously checked. If received, a switching control signal (a) is issued to the switch unit 270, and the connection terminal (b) of the priority broadcasting speakers 411, 421, and 431 is transmitted. ) is switched from the first terminal (c) of the amplifier 320 of the public address system 300 to the second terminal (d) of the power amplifier 220 of the alarm terminal device 200 (S3) .

Afterwards, disaster and civil defense broadcasts are immediately transmitted to the first priority broadcasting speakers (411, 421, 431) through the power amplifier 220 (S5). At this time, the disaster and civil defense broadcasts are stored in the alarm information storage unit 250. It is desirable to use pre-stored sound sources.

Immediately thereafter, through the external amplifier monitoring and speaker control unit 210, the lines of the first priority broadcasting speakers 411, 421, and 431 are inspected (S7), and line abnormalities are checked (S9). Otherwise (if the output is normal), a wake-up signal is immediately output to the emergency panel 340 of the public address system 300 through the external broadcasting equipment-linked data processing unit 230 (S11), and for a moment After waiting, has the public address system 300 woke up? The presence or absence is checked (S13).

Therefore, if it is determined that the wake-up state is in the wake-up state as a result of the check in step S13, the stored sound source pre-stored in the alarm information storage unit 250 according to the reception protocol is transmitted to the emergency panel through the external broadcasting equipment linked data processing unit 230. It is transmitted to (340), so that disaster and civil defense broadcasts are made to all speakers (400) by the public address system (300) (S15).

Afterwards, the amplifier 320 inspects the broadcasting line output to all speakers (S17) and checks whether the broadcast signal is being output normally (S19). If the broadcast signal is being output normally, at S3 Contrary to the step, a switching control signal (a) is issued to the switch unit 270, and the connection terminal (b) of the priority broadcast speakers (411, 421, 431) is connected to the power amplifier (220) of the alarm terminal device (200). A switching return is performed to switch from the second terminal (d) to the first terminal (c) of the amplifier 320 of the public address system 300 (S21).

Meanwhile, if it is determined that the broadcast signal is not being output normally as a result of the check in step S19, it is determined that there is a problem with the public address system, and an audio and visual alarm is sent through the information display unit 260 or LTE. After sending a warning text to the manager's mobile device through the module 280 (S23), it returns to the beginning.

Similarly, in step S13, did the public address system 300 wake up after outputting the startup signal and waiting for a while? When the public address system 300 does not wake up, an alarm and warning text is issued to notify the manager. However, in this case, the public address system 300 wakes up. Considering time, has a certain amount of time (usually about 10 seconds) elapsed since the startup signal was output? (S14), and if a certain period of time has not yet elapsed, steps S11 to S13 are repeatedly performed to output a startup signal again and check whether or not to wake up. Conversely, as a result of the determination in step S14, a certain period of time ( Only when 10 seconds (usually about 10 seconds) has elapsed, the process proceeds to step S23, and an alarm and warning text is issued.

On the other hand, as a result of the check in step S9, if it is determined that the line of the first priority broadcast speaker (411, 421, 431) is abnormal (not normal output), an alarm and warning text is issued to notify the manager. Let's do it.

However, since it is an emergency situation, it is inevitable that it will take time to repair even if the manager is notified. More preferably, as a result of the check in step S9, if the line of the first priority broadcast speaker (411, 421, 431) is abnormal. Even if it is determined that the output is not normal, before issuing the alarm and warning text, after transmitting the disaster and civil defense broadcast through the second priority broadcasting speaker (not shown) (S31), the alarm and warning text are issued. (S33), check once or twice whether the line of the first priority broadcasting speaker (411, 421, 431) has been restored (S35), and if it has not been restored, an alarm and warning text is issued (S33) ), if it is determined that the line of the first priority broadcast speaker (411, 421, 431) has been restored, it is better to return to step S5 and proceed again from the beginning.

Although the present invention has been described above according to an embodiment of the present invention, changes and modifications made by those skilled in the art without departing from the technical spirit of the present invention do not fall within the scope of the present invention.
