Abstract

An embodiment relates to an emergency broadcasting control system. Specifically, such an emergency broadcasting control system switches and broadcasts only a relevant area/group/channel when disasters and disasters are detected from various nearby disasters/disaster detection sensors, for example, through fire receivers and fire voice recognition boards, under the situation of internal broadcasting as before. Also, in the case of switching broadcasting in this way, each disaster/calamity detection sensor device is given a different priority according to the disaster/calamity type and performed sequentially for each device. Therefore, basically, when a variety of information is broadcasted, network broadcasting is performed by each group or individually at the same time, and thus multi-channel multi-cross broadcasting is performed. Also, in this case, if disasters and calamities are detected by nearby fire receivers and fire detection sensors under the circumstances of network broadcasting, switchover broadcasting is selectively performed in a corresponding area/group/channel to provide immediate broadcasting in an emergency.

1 is a supplementary view for conceptually explaining an emergency broadcast control system according to an embodiment.

As shown in Figure 1, the emergency broadcast control system according to an embodiment is first, as before, when broadcasting in schools, offices, various premises, etc., by a number of different areas (see a in Figure 1, here A W, B, etc.) In the installed network broadcasting system, the area/group/channel is grouped according to the administrator's wish and broadcast over the network, so that broadcasting is provided according to various broadcasting environments and broadcasting targets.

For example, in such a broadcast, there are A zone, B zone, C, D, E inside, and F, G, ... N, etc. In the network broadcasting system, partial broadcasting is performed by grouping A, B, and D within the same network (see b). At this time, C and E perform cross broadcasting with different broadcasting information.

In addition, only a specific area A is individually broadcast, and the entire broadcast is performed in all internal and external areas using A to N, etc., and furthermore, in area A, each grade level in school, for example, with several groups and channels. This type of broadcasting is achieved by performing broadcasting for each (group) and each class (channel).

So, in this state, according to an embodiment, when disasters and disasters are detected by the surrounding fire receivers and fire detection sensors, etc., under the situation where broadcasting is performed for each area/group/channel in this way, each area/group/channel Only that part is transferred and broadcast.

And, in the case of performing the switchover broadcast in this way, different priorities are given to each disaster/disaster detection sensor device for each disaster/disaster type, and each device is sequentially performed.

In addition, since settings related to areas/groups/channels are synchronized in real time with each of these related devices, etc., the related DB is matched and maintained to broadcast the actual help.

First of all, before explaining the transfer broadcasting, the above-mentioned conventional broadcasting is briefly described, so that the understanding of the transfer broadcasting is to be aided.

Specifically, the existing system largely includes a main information processing device 100 , a power distributor 150 , and a network I/O master 140 for internal network broadcasting. In addition, it also includes a plurality of amplifiers 160, a speaker selector 170, and an audio output unit including a speaker.

And, in this case, the remote microphone 110 is further included to provide network broadcasting directly in the field.

In addition, such a system may include a mobile terminal such as a mobile phone 100-11 or a tablet 100-12 of an administrator in order to perform network broadcasting even in a remote location.

For example, in the network broadcasting system of area A, in order to perform network broadcasting with the network broadcasting system and/or the manager mobile terminals 100-11 and 100-12 in another area B from the outside, the audio encoder 130 is includes

In particular, the transceiver 180 is further included in order to directly transmit broadcast information from the manager mobile terminals 100-11 and 100-12 in relation to one embodiment to perform network broadcast immediately.

And, additionally, for networking inside and outside, a hub (h) and a gateway (g) are also included.

For reference, the basic configuration will be described a little more as follows.

In the case of network broadcasting, the main information processing device 100 sets and transmits basic broadcasting information to be broadcast according to an administrator key operation for each region/group/channel desired by the administrator, and manages the whole. For example, such basic broadcasting information is systematically provided by a broadcasting company, etc. through a CD player and a tuner, and also directly provided by a manager in the field through the remote microphone 110 . In this case, in general, the main information processing apparatus 100 operates a broadcasting system by frequently changing network broadcasting setting information and the like with various programs. In addition, related services are, for example, a speaker selector and control system that checks for abnormalities for each channel of a speaker line, and turns on/off while listening to an output sound state. In addition, the main information processing device 100 is configured with a window-based GUI in case of public address broadcasting, and thus efficiently controls, manages, searches, and broadcasts public address broadcasting. At this time, it is manufactured as an industrial server so that it has excellent durability and safety, and is suitable for 24-hour operation. And, the software is a form used for remote control support by the mobile terminal, that is, the mobile phone 100-11 and the tablet 100-12.

When the network broadcast is performed through the main information processing device 100 in this way, the power distributor 150 receives broadcast driving power from a plurality of different power sources and distributes it to each internal unit. So, through this, the power of the rack equipment is normally supplied, and in the event of a power outage, it is systematically converted from AC power to DC power (battery) and DC power is supplied preferentially.

When the network I/O master 140 transmits the broadcast information of the main information processing device 100 by different regions/groups/channels from the inside, the network I/O master 140 receives the broadcast information from the main information processing device 100 and receives the corresponding channel. etc. to multiplex and broadcast.

On the other hand, in addition to this, in the case of network broadcasting in this way, the existing system transmits broadcasting information for each network broadcasting system through the administrator's mobile terminals 100-11, 12, etc. even at a remote location, so even if the administrator is far away Remote broadcasting from outside.

Therefore, through this, the network broadcasting system provides broadcasting to many areas at once, or provides broadcasting to various buildings or relatively distant places, thereby providing various user convenience services.

That is, network broadcasting is also performed internally/externally from other network broadcasting systems in the vicinity or the administrator's tablet or mobile phone, and for this purpose, the following configuration is included.

First, when the audio encoder 130 transmits broadcast information to the outside through the main information processing device 100, the audio encoder 130 converts the corresponding broadcast information into a network signal to be converted into a network signal in another external network broadcasting system or a mobile terminal of an administrator. (100-11, 12) and so on. In this case, the audio encoder 130 receives, for example, up to 8 channels of line output signals from source devices such as CD players and tuners and analog audio signals such as remote microphones, and converts them into 8 channels of network signals and transmits them. do. Also, at this time, the audio input state for each channel can be easily checked.

In particular, the transceiver 180 related to an embodiment collects internal/external broadcasting information transmitted by the audio encoder 130 or the mobile terminals 100-11 and 12 when performing network broadcasting with the outside in this way, and It is broadcast by multiplexing for each area/group/channel. For example, the transceiver 180 receives up to 5 channels of network audio signals of the audio encoder !30 and mixes and outputs them without a separate audio mixer.

At this time, in order to actually transmit the broadcast to the outside, a plurality of amplifiers 160, speaker selectors 170, and speakers are installed differently for each area/group/channel, and network broadcast is performed only at the location desired by the administrator.

For reference, the plurality of amplifiers 160 are installed for each internal/external, that is, for each network I/O master 140 and transceiver 180, and are also installed to correspond to a number of different areas/groups/channels, In this way, a plurality of broadcast information is amplified.

In addition, the plurality of speaker selectors 170 select to broadcast only through a specific channel or the like when an abnormality occurs. In this case, the plurality of speaker selectors 170 operate the speakers by, for example, 16 individual, group, and total selection switches of the output signals of up to 8 power amplifiers. In particular, each channel has a 3-wire speaker line checker function during normal real-time broadcasting. Also, a function of transmitting a real-time audio output signal during broadcasting to a network for remote monitoring for each channel is provided.

In addition, a plurality of speakers subdivide broadcasting information into respective channels, etc. and output, for example, by being installed for each area and assigned an individual IP address. At this time, such a speaker may also be used in parallel with the form 190 using a digital amplifier or the amplifier built-in speaker 191.

On the other hand, in the existing system, when the hub (h) performs network broadcasting from the inside and the outside, the broadcast information inside each system is transmitted between the respective units, for example, in the main information processing device 100, the network I/ It relays to the O master 140 or from the audio encoder 130 to the gateway g. And in this case, the hub (h) is, for example, composed of a network gateway, is used in connection with the internal network and the external network, and is TCP/IP capable of using multicast packets used in the internal network in the external network. to send and receive.

Then, when network broadcasting is performed in this way, the gateway g transmits broadcast information from the outside of each system to each other, for example, by connecting the system of area a and the system of area b, or the system of area a and Since the manager mobile terminals 100-11 and 12 are connected, it is relayed.

Therefore, the conventional broadcasting is performed through this.

On the other hand, in this state, according to one embodiment, in addition, at this time, in the case of detecting the occurrence of disasters and disasters through various sensors in the vicinity, for example, a fire receiver and a fire detection sensor, transfer broadcasting is performed. to perform (see FIG. 2).

Therefore, if a disaster/disaster occurs while broadcasting for each area/group/channel, it is immediately broadcast by switching only the corresponding area, group, and channel. In addition, these transfer broadcasts include emergency/information broadcasts through the manager.

In addition, if you look at the actual situation that is the technical background, when it is checked whether a fire has occurred through the fire receiver, in an emergency situation that needs to be broadcasted to the area/group/channel where the fire occurred, the You have to connect and turn on only the relevant part, and turn off the rest and other broadcasts to broadcast.

The configuration of such a transfer broadcast will be described in more detail with reference to the following drawings and the like.

2A is a diagram for conceptually explaining an emergency broadcast control system according to an embodiment.

First, as shown in FIG. 2A, the emergency broadcast control system of an embodiment determines whether a disaster or disaster has occurred through the surrounding fire receiver 100, etc. when the emergency broadcast controller 200 performs the existing broadcast as described above. When detected, it switches and broadcasts for each area/group/channel, that is, to a place related to the disaster/disaster occurrence (refer to a).

In this case, specifically, the emergency broadcast controller 200 switches the broadcast information of the main broadcast information processing device (for internal use) differently for each corresponding area/group/channel according to whether a disaster/disaster is detected, Broadcast through each speaker (300).

In addition, in the case of performing the switchover broadcast in this way, different priorities are given to each disaster/disaster detection sensor device for each disaster/disaster type, and the respective devices are sequentially performed.

In this case, the priority is, for example, first to give a priority order to the surrounding fire receiver, and secondly to give the order to the fire detection sensor, fire voice recognition board, etc.

Therefore, when switching broadcasting is required, broadcasting information is preferentially transmitted only in the corresponding area/group/channel, and an important situation is immediately notified to the people around the group.

And, in addition to this, since the settings for the area/group/channel are synchronized with each other in real time in various related devices, etc., the related DB is matched and maintained to broadcast the actual help.

2B is a diagram for explaining another concept applied to an emergency broadcast control system according to an embodiment.

As shown in FIG. 2B , the emergency broadcast control system according to an embodiment is a different concept, and various convenience services are provided by using various methods from the example below.

First, such a system broadcasts only the corresponding area/group/channel portion in the emergency broadcast controller 200 by turning on and broadcasting under an emergency situation in which a disaster/disaster should be broadcast to an area/group/channel. Then, other broadcasts in the remaining part are turned off to perform transfer broadcast.

In this case, in connection with the manager mobile terminal 110, different types of transfer broadcasting are provided differently, for example, additional transfer broadcasting or multimedia transfer broadcasting, which gives a little more convenience.

And, these additional transfer broadcasts are as follows.

1. Example 1

First, the manager mobile terminal 100 provides a number of different remote additional broadcast information including disaster/disaster/safety guide text, notice and alarm, manager guide text including reservation, manager event text, manager guide voice, manager event voice It is broadcast by the corresponding area/group/channel with the setting mobile app.

Then, the emergency broadcast controller 200 of an embodiment performs the following operation.

a) First, when performing the transfer broadcast, the broadcast information type of the remote supplementary broadcast information by the manager mobile terminal 110 is checked from the setting format.

b) As a result of the above check, if the broadcasting information type is text, it is converted into broadcasting information by the internal TTS engine and turned on/off, and if the broadcasting information type is voice, it is turned on/off without conversion make a breakout broadcast.

2. Example 2

Next, the manager mobile terminal 110 also performs the following operations.

a) First, when the remote supplementary changeover broadcast information is broadcast, the information is also provided to a plurality of broadcast target mobile terminals 110 belonging to the corresponding area/group/channel.

b) Then, the broadcast information type of the information is checked in the format for each of the plurality of broadcast target mobile terminals.

c) As a result of the check, if the broadcast information type of the remote additional broadcast information is text, it is converted into broadcast information by the internal TTS engine of the corresponding mobile app and turned on/off, and if the broadcast information type is voice, it is not converted Since it is turned on/off without being on/off, an additional transfer broadcast is performed at a remote location.

3. Example 3

On the other hand, the main broadcast information processing apparatus performs the following types of operations.

First, a plurality of different basic additional broadcasting information including manager guide text including management notice, alarm, and reservation, manager event text, manager guide voice, and manager event voice are broadcast for each corresponding area/group/channel.

Then, the emergency broadcast controller 200 performs the following operation.

a) That is, when performing the switchover broadcasting, the basic additional broadcasting information broadcasting information type from the main broadcasting information processing device is checked in the format.

b) As a result of the check, when the broadcast information type of the basic additional broadcast information is text, it is converted into broadcast information by the internal TTS engine and turned on/off, and when the broadcast information type is voice, it is turned on/off without conversion. , real-time supplementary transfer broadcasting is performed.

4. Example 4

On the other hand, the following types of operations are also performed.

First, when the manager mobile terminal 110 broadcasts the remote supplementary transfer broadcast information, the corresponding broadcast information for disaster/disaster/safety guide text is systematically transmitted at the time of reception.

Then, the emergency broadcast controller 200 systematically converts the disaster/disaster/safety guide text from the manager mobile terminal 110 into broadcast information in the format by the internal TTS engine when performing the transfer broadcast. /off, so an emergency sub-transfer broadcast is made.

Next, such multimedia transfer broadcasting is, for example, as follows.

First, the manager mobile terminal 110 performs the following operation.

a) Specifically, when the remote supplementary transfer broadcasting information is transmitted, the shooting operation of the internal camera is started and performed according to the administrator setting, or by extracting the recorded broadcasting, moving picture, and photo corresponding to the inside, the on-site situation Acquire a broadcast image about

b) Then, the broadcast image information is provided in real time as a set communication channel for each corresponding area/group/channel.

Then, the emergency broadcast controller 200 converts the broadcast image of the manager mobile terminal 110 according to the resolution information for each different broadcasting device and turns it on/off in the case of the transfer broadcasting, so that the multimedia transfer broadcasting is performed.

On the other hand, such supplementary transfer broadcasting and multimedia transfer broadcasting, etc. provide broadcasts that actually help by extracting broadcast target information from the inside of the manager mobile terminal 110 when each broadcast is performed.

Specifically, the manager mobile terminal 110 extracts and registers the broadcast target information from the internal phone number list or the SNS list in real time for each area/group/channel when broadcasting information for remote supplementary transfer broadcasting to the broadcast target, and registers the corresponding It provides actual information to the target audience.

3A is a diagram illustrating an emergency broadcast control system as a whole according to an embodiment.

As shown in Figure 3a, the system according to an embodiment provides a plurality of different disaster/disaster detection sensors (100-1, etc.) provided in various places around and a plurality of voice recognition functions connected thereto through a self-network. It includes an emergency broadcast controller 200 used.

And, in this case, the emergency broadcast controller 200 connects the aforementioned internal main broadcast information processing device (not shown) to a speaker, etc. for each different area/group/channel.

In this case, the self network uses a TCP/IP network, an LTE network, a wireless communication network, or the like.

Additionally, such a system interworks with an external linkage in relation to network broadcasting, such as a hospital management device (not shown), an education management device 400-1, a police station management device 400-2, and the like.

The emergency broadcast controller 200 basically provides an internal broadcast. At this time, when information on disasters and disasters is additionally collected from a number of different disaster/disaster detection sensors (100-1, etc.) provided in various places around By transmitting through , transfer broadcasting is provided. And in this case, the emergency broadcast controller 200 controls the broadcast operation for each area, group, and channel in a broadcast format desired by the manager, for example, individually broadcast, all broadcast, cross broadcast, etc. Because it controls, various kinds of broadcasting are basically provided. At this time. In this state, according to an embodiment, the emergency broadcasting controllers 200-1, 200-2, ... , perform switchover broadcasting according to an embodiment in connection with the above-described broadcasting, so that the emergency broadcasting controller 200-1, 200-2, ... It offers a lot of broadcasts.

3B is a block diagram illustrating the configuration of an emergency broadcast controller applied to an emergency broadcast control system according to an embodiment.

As shown in FIG. 3B , the emergency broadcast controller 200 according to an embodiment includes an interface unit 201 and a switching unit 202 , a voice driving unit 203 , a key signal input unit 204 , a display unit 205 and a control unit 206 .

Additionally, the emergency broadcast controller 200 according to an embodiment includes an FPGA 207 and a sensor unit 208 .

The interface unit 201 includes a main broadcast information processing device inside, and a plurality of different disaster/disaster detection sensors 100 including a fire receiver or a voice recognition board for recognizing a fire sound, and an earthquake sensor in one batch Connect. Additionally, in this case, the interface unit 201 collectively collects disaster/disaster sensing information from various A/I modules, D/I modules, and communication modules. In addition, the interface unit 201 is also connected to a speaker installed for a plurality of different areas/groups/channels in the main broadcast information processing apparatus for outputting broadcast information.

The switching unit 202 turns on/off the broadcast information of the main broadcast information processing device for each corresponding area/group/channel.

The voice driving unit 203 converts the broadcasting information turned on/off by the switching unit 202 into voice and outputs it to a speaker. For example, the voice driver 203 provides sound and tone suitable for current broadcasting. In this case, the voice driver 203 separates the broadcasting-related digital signal for each channel and individually adjusts the sound and tone.

When the broadcast information converted by the audio driver 203 is digital, the key signal input unit 204 converts it to analog and outputs it to the speaker.

The display unit 205 displays notification information for outputting the broadcast information.

The control unit 206 controls the operation of each unit. That is, when receiving various types of broadcasting information, the administrator transmits the broadcasting information in different areas/groups/channels desired, so that broadcasting is performed to various places at different times. In this case, according to an embodiment, the controller 206 a) controls the on/off operation of the switching unit 202 when outputting the broadcast information to transmit the broadcast information of the main broadcast information processing device. Depending on whether each disaster/disaster detection sensor detects a disaster/disaster, it switches and broadcasts differently for each corresponding area/group/channel. b) Also, in the case of the switching, different priorities are given to each disaster/disaster detection sensor device for each disaster/disaster type, and each device is sequentially performed.

The FPGA 207 registers in advance a first format for converting broadcast information for a plurality of different audio formats when delivering such broadcast information, and converts the current broadcast information according to the audio format designated by the manager. is provided at an appropriate volume and tone. In this case, the audio format is MP3-1, MP3-2, PC audio, digital audio, and the like. As a specific example, the FPGA 207 has 2 I2S 2 channels of MP3, 1 I2S 1 channel of PC audio, and 16 digital audio TDM channels at the input terminal. In addition, the output terminal has 16 TDM channels of two ports and 8 TDM channels of one port. Also in this state, the FPGA 207, for example, under the control of the control unit 206, the conversion data format related to the bit and sampling for each different audio format is defined and determined, so that the data conversion between audio formats do. At this time, when the broadcast information is converted by the FPGA 207 , the controller 206 registers in advance a second format for adjusting the sound for each audio format, so that the broadcast information can be recorded differently according to the current audio format desired by the administrator. Adjust. In addition, in this case, there is a situation in which it may be a little difficult to smoothly listen to the broadcast sound and tone according to the surrounding broadcast conditions in the actual field.

The sensor unit 208 interlocks with various sensors that measure earthquakes, smoke, flames, air pollution, etc. using the Internet of Things, etc. in connection with the actual surrounding conditions, so that the broadcast volume is adjusted to suit the actual broadcasting environment. Provides convenience. To this end, the embodiment further includes a sensor unit that is installed for a plurality of different speakers, senses the surrounding state information in which each speaker is installed, and provides the information to the control unit 206 . Therefore, the control unit 206 a) registers in advance an audio format or a third format for converting a sound differently in response to a plurality of different ambient conditions. b) So, when the ambient information is provided in this way, the audio format conversion operation of the FPGA or the audio conversion operation of the audio driver is controlled from the third format, and the audio format and the sound are converted differently for each current ambient state. do.

On the other hand, the emergency broadcast controller 200 implements an improved broadcast system by collecting surrounding state information to be broadcast from various sensing data when performing a switchover broadcast.

To this end, the control unit 206 sequentially performs the following operations.

First, the control unit 206 collects overall sensing data for each of a plurality of different sensors that collect ambient state information of the speaker terminal.

And, since the required time and the sensing amount are learned for each of a plurality of different sensors, and the required time and the sensing amount are predicted for each different model from the learning result, a predictive data model is generated according to the following contents.

# predictive data model

1. First, the prediction data model defines a learning model for the required time and sensing amount for a plurality of different sensors.

2. Then, based on the initial point of the sensing data, a sensing amount and a data set are generated.

3. Next, the properties of the required time and sensing amount are added for each of a number of different sensors.

4. Then, the properties of the required time and sensing amount are determined for each of a number of different models.

5. So, normalized data is generated from the determined result.

6. Then, set the independent and dependent variables by setting the required time and sensing amount for each model.

7. Next, learning and training data are generated for the set result.

8. So, through this, a deep learning-based learning model is generated from the generated result.

Next, when the surrounding state information is provided by the sensor in such a state, each sensing data related to the current surrounding state information is collected as a whole to check a required time and a sensing amount.

Then, the required time and the sensing amount are compared with the previously predicted required time and the sensing amount of the corresponding model.

As a result of the comparison, if the difference between the two values is a value corresponding to the preset lower limit threshold and the upper limit threshold, it is confirmed as normal, whereas the difference between the two values is a value corresponding to the lower limit threshold and the upper limit threshold. If it is out of , check above.

So, when the above abnormality occurs, an alarm is generated by itself.

In addition, a method of generating the aforementioned predictive model, that is, a learning model, will be described in more detail.

First, this method of generating a learning model generates a learning model for the required time and sensing amount for each of a plurality of different sensing devices. In addition, since the required time and sensing amount patterns vary according to ambient conditions, for example, temperature, weather, and location, a model is created by classifying the dataset. Therefore, a model may be newly created for each issue of the speaker, or a model may be created with a bundle of several facilities by setting standards. This allows us to determine the appropriate method according to the characteristics of the data.

Next, in the case where a large number of data cannot be collected due to errors in ambient conditions and devices from the data collected in real time, or when a significant low temperature anomaly occurs, the corresponding data file is removed. Then, after the basic data set is created, additionally required accumulated time required and sensing amount attributes are added.

In addition, when some data is not collected due to data interruption, the corresponding data is removed.

Next, we determine valid attributes for different models, generate normal values, and then determine independent and dependent variables. For example, the required time model may use cumulative minutes, accumulated sensing amounts, and temperature as valid independent variables, and set required time as dependent variables.

Then, in order to generate a learning model, learning and training data are generated from the entire data. In general, 70% of the entire dataset is used as training data, and 30% is used as training data to test the model after model creation. Next, we create a learning model. At this stage, it is decided which learning model to use. For example, it refers to a configuration in which the number of final outputs is set by configuring the necessary layers based on deep learning to configure the input and output layers. If the generated model is evaluated and the error rate is satisfied with the model, the model is simulated with new data. If the model update is not required, the training model is saved and used as a predictive model.

4 is a flowchart sequentially illustrating the operation of the emergency broadcast control system according to an embodiment (refer to FIG. 3).

As shown in FIG. 4 , the emergency broadcast control system of an embodiment first converts the broadcast information of the main broadcast information processing device to the manager setting information in the emergency broadcast controller 200 when broadcasting to multiple broadcast areas as in the prior art. Since the broadcast is grouped differently for each specific area/group/channel, multi-channel multi-cross-broadcasting is performed for each location desired by the manager.

In this state, the emergency broadcast controller 200 according to an embodiment additionally performs a switchover broadcast.

That is, as described above, when outputting the existing broadcast information, the emergency broadcast controller 200 controls the on/off operation of the switching unit to transmit the broadcast information of the main broadcast information processing device to the surrounding area. Depending on whether the fire receiver and the fire voice recognition board 100 detect disasters/disasters, the broadcasting is performed differently for each corresponding area/group/channel.

And, in the case of switching in this way, different priorities are given to each disaster/disaster detection sensor device for each disaster/disaster type, and each device is sequentially performed.

Therefore, when disaster/disaster broadcasting is required, broadcasting information is preferentially transmitted only in the corresponding area/group/channel to immediately notify people in the vicinity of an important situation.

As described above, one embodiment detects disasters and disasters by interworking with various disaster/disaster detection sensors such as fire receivers, fire detection sensors, and fire voice recognition boards in the vicinity under the condition of broadcasting by area/group/channel as before. In this case, only the relevant area/group/channel is switched and broadcast.

And, in the case of performing the switchover broadcasting in this way, different priorities are given to each disaster/disaster detection sensor device differently for each disaster/disaster type, and the respective devices are sequentially performed.

Therefore, when disaster/disaster broadcasting is required through this, broadcasting information is preferentially transmitted through only the corresponding area/group/channel, and an important situation is immediately notified to the people around it.

On the other hand, additionally, in case of such an emergency broadcast controller, when performing this transfer broadcast, the transfer broadcast is performed variously by various hardware, software, and line for broadcasting, so that the transfer broadcast is performed according to the actual situation in which broadcasting facilities are used in different ways. do.

To this end, the switching unit in the emergency broadcast controller is configured as follows.

That is, the switching unit presets the matrixed I/O on/off conversion operation in correspondence with different hardware and software for broadcasting and for each line type, and performs I/O on/off conversion according to the current hardware, software, and line type. It is performed differently and the broadcast is switched for each broadcasting facility.

For example, hardware is a broadcasting server, software is a broadcasting program or mobile app, and lines are various types of networks.

So, if the hardware performance is good, I/O on all the speakers belonging to the corresponding channel even if it is the same channel in a specific situation, and in the case of general performance, I/O on only some of the speakers, and I/O on each hardware. The off-conversion is performed differently.

Alternatively, in addition to this, a switchover broadcast is also performed for each broadcast abnormal situation, and for this purpose, it has the following configuration.

Specifically, the switching unit presets the matrixed I/O on/off conversion operation in response to each abnormal type for network broadcasting, and performs I/O on/off conversion differently according to the current abnormal type to perform a broadcast abnormal situation. Broadcast not so much.

For example, this type of abnormality is a broadcasting server error or line error, etc., and when an error occurs in the line of a specific channel, I/O on/off conversion is performed instead of the channel designated by the administrator as a spare, so that more It provides a transfer broadcasting service.

Furthermore, under such an abnormal situation, a slightly better form of switching broadcasting is provided for each area/group/channel.

Specifically, when there is an abnormality in broadcasting, the switching unit controls the I/O on/off operation from a neighboring broadcasting facility or an external control device belonging to the current region/group/channel to switch broadcasting for each broadcasting region/group/channel. do

For example, this control first registers the first format.

That is, with respect to the first format, if the broadcasting state of the broadcasting server corresponds to the set normal state, the broadcasting is maintained as it is, and if it does not correspond to the normal state, the other management information processing apparatus and the manager currently perform the same group broadcasting. It is set to perform redundant control as a mobile terminal or the like. In this case, other devices perform in such a way that the I/O master authority is granted in the order of proximity due to the adjacent distance or the like.

Therefore, in case of internal broadcasting, the current broadcasting state is checked in real time according to the first format.

As a result of the check, if the current broadcasting state corresponds to the normal state, the broadcasting is maintained as it is. On the other hand, if it does not correspond to the normal state, the same group broadcasting is currently performed, that is, the broadcasting information processing device adjacent to the same area/group/channel or the manager mobile terminal is controlled in a redundant manner.

On the other hand, in a newer form, the emergency broadcast controller according to another embodiment provides a more diverse switchover broadcast service because, in this case, the switchover broadcast is performed at a remote location and in the vicinity from the following technical features.

For example, such a transfer broadcast is as follows.

First, such broadcasting is performed, for example, in case of disasters, disasters, or fires such as wildfires in a specific place. And, additionally, it is performed when there are various announcements, alarms, reservation notifications, etc. to specific groups and individuals, repair and maintenance of the device in use, and when events such as various celebrations occur.

Specifically, first, a disaster and information on whether a disaster has occurred are transmitted remotely from the manager's mobile terminal or the like.

That is, information on disasters and disasters, or disaster/disaster/safety guide text, notice and alarm, manager guide text including reservation, manager event text, manager guide voice, etc. Broadcast transmission by /group/channel.

Then, for each area/group/channel, that is, the corresponding switching unit receives the corresponding information remotely and checks the data format type.

As a result of the above check, if the data format type of this information is text, it is converted into voice by its own TTS engine in the switching unit, and if the data format type is voice, I/O is turned on/off without conversion.

And, as a specific example, when specific information such as disaster/disaster/safety guide text is received from the outside in the mobile terminal, emergency guide information is received within the disaster area or in the area/group/channel of some area desired by the manager. By providing the system immediately at the time, transfer broadcasting is performed immediately in an emergency situation.

At this time, the corresponding switching unit converts it into voice by its own TTS engine.

On the other hand, in addition, in such a transfer broadcasting, since the broadcasting target information is secured and maintained in real time from the following configuration, the transfer broadcasting service is also provided to groups and individuals.

To this end, each broadcast target information is registered in advance for a plurality of different areas/groups/channels in the main broadcast information processing apparatus or the mobile terminal.

In this case, such related broadcast target information is detected from a list of phone numbers within itself or a list of registered SNS groups. That is, when there is the same name as the broadcast target in each list, it is detected through real-time synchronization and the same is maintained.

Therefore, when the corresponding remote information is broadcast, broadcast target information is extracted for each area/group/channel, and a switchover broadcast service is collectively provided to each group and individual.

Therefore, a practical example can be given. In the case of receiving a disaster/disaster/safety notice message sent from the outside to the general public from the manager's cell phone, the text information is immediately sent to the disaster area or to specific groups and individuals desired by the manager. send.

In this case, the emergency/disaster/safety guide text is determined according to, for example, a set risk level, and is transmitted immediately if it is higher than the risk level.

So, through this, if there is a specific school in a place belonging to disaster/disaster/safety, broadcasting is performed in each classroom for a specific grade and class in a remote location, and broadcasting is also performed to each teacher and students, so the corresponding target provides a comprehensive transfer broadcasting service to

In addition to this, as another form of such transfer broadcasting, it is additionally provided as multimedia broadcasting as follows.

To this end, such a system initiates and performs its own camera shooting operation in the main broadcasting information processing device or in the administrator mobile terminal according to the administrator setting, when transmitting switching information, or performing the corresponding recorded broadcasting, the corresponding moving picture, By extracting photos, broadcast images related to the field situation are obtained.

Then, such broadcast image information is immediately provided as a communication channel set for each area/group/channel.

Therefore, since the main broadcasting information processing device and the manager mobile terminal convert and provide such a broadcasting image according to the resolution information for each broadcasting device designated in advance, the switching broadcasting is provided in the form of multimedia broadcasting.
