Is transmitted to the control room device 20.

The collecting operation of the user terminal identification information of each of the disaster situation display devices 11-1n may be performed periodically at set time intervals.

Accordingly, when a disaster occurs, user identification information for a driver of a vehicle or a user terminal of a person located around the disaster situation display device 11-1n is obtained within a set time from the time the disaster occurs.

Next, with reference to FIGS. 4A to 4D, an operation of the disaster situation display system according to an embodiment of the present invention, that is, data flow between components of the disaster situation display system will be described.

For convenience of explanation, one of the plurality of access road display devices searched among the plurality of disaster display devices 11-1n is assumed to be the first disaster display device 11 and one of the plurality of searched disaster location display devices Is assumed to be the second disaster situation display device 12.

In addition, one of the plurality of access road user terminals searched among the plurality of user terminals 41-4p is assumed to be the first user terminal 41, and one of the plurality of searched disaster location user terminals is the second user terminal 42. I assume.

First, when a disaster occurrence signal such as a fire report is received or detected in the situation room, the person in charge of the situation room inputs the disaster occurrence information using the user input unit of the situation room server 21 (S21). At this time, the disaster occurrence information may include the type of the disaster (that is, the type of disaster) and the location of the disaster.

In this way, when the disaster occurrence information is input (S21), the control unit of the situation room server 21 determines the location of the disaster (that is, the location of the disaster occurrence) using the location of the disaster occurrence and Disaster-related organizations related to the type of are determined (S22).

Then, the control unit of the situation room server 21 searches the location of the disaster occurrence and the location of the disaster-related institution on the map using the map database 23 (S23), and is located at the shortest distance from the location of the disaster occurrence among the searched disaster-related organizations. The disaster-related technology is searched and the shortest entry route to the disaster occurrence location is searched (S24).

Next, the control unit of the control room server 21 checks the location information of the searched shortest entry path, and searches for a disaster situation display device, that is, the display device 11 on the access road, located in the entry path searched in the display device database 22 (S25).

In this way, when the access road display device 11 located on the shortest access route to the disaster occurrence location is searched, the control unit of the control room server 21 performs the driving sequence of the detected plurality of access road display devices (i.e., lights up). Order) is determined (S26).

Since the control unit of the situation room server 21 already knows the location of the searched disaster-related agency and the location of the disaster, it is possible to know the entry direction when the related vehicle (i.e., disaster-related vehicle) of the disaster-related agency is dispatched to the disaster-related location. have.

Accordingly, the control unit of the control room server 21 uses the installation location information of each disaster situation display device 11-1n stored in the display device database 22 to provide the access road located closest to the disaster-related institution. First, the driving sequence of the display device on the access road located at the farthest from the disaster-related organization (ie, the closest location to the disaster occurrence location) is determined last. For this reason, the order of lighting of the searched display devices on the plurality of access roads is sequentially turned on from the disaster-related organization toward the disaster occurrence location.

In this way, when the driving order of the detected plurality of access road display devices is determined, the control unit of the control room server 21 transmits a disaster notification request message including the corresponding driving order determined to each access road display device 11 Do (S27).

The disaster notification request message may include a method of driving a disaster notification unit, an order of driving a display device, a type of disaster, information on a location of a disaster, and the like. However, in the disaster notification request message, at least one of these information may be omitted or new information may be added.

Therefore, when a disaster notification request message is transmitted from the control room server 21 through the control room communication module 1011, the control unit 102 of the display device 11 on the access road stores the transmitted disaster notification request message. ), and then determines the transmitted driving sequence (S28), and drives the indicator 105 to a corresponding state (eg, a first state) at a driving time that matches the determined driving sequence (S29).

At this time, the first state of the indicator 105 is a sequential blinking state in which the indicator 105 of the display device on each access road blinks in a predetermined order.

Since the lighting time and the light-off time of each indicator 105 for sequential flashing are already determined in the storage unit 103, the control unit 102 flashes its own indicator 105 by using the set lighting time and the light-off time. The operation is controlled according to the specified driving sequence.

At this time, the driving time of the indicator 105 is determined according to the time when the disaster notification request message is transmitted and the driving sequence.

For example, if the driving sequence is the first, the control unit 102 starts flashing the indicator 105 immediately at the time of transmission, and if the driving sequence is the second, the delay time (e.g., 0.5 seconds) is determined from the transmission time. After) elapses, the corresponding indicator 105 can be started to blink. That is, a delay time for controlling blinking of the corresponding indicator 105 may be determined according to a predetermined driving sequence.

Accordingly, the plurality of searched access road display devices are controlled to blink according to a predetermined order by performing a disaster occurrence location, so that the lighting conditions of the plurality of access road display devices that are controlled to be blinked have a directionality indicating the disaster occurrence location.

Therefore, by using the lighting situation of the display devices on the plurality of access roads, drivers of nearby vehicles and people around them can recognize the driving direction of the disaster-related vehicle to enter the disaster occurrence location. Driving or walking in a direction that is not possible.

Next, the control unit 102 of the access road display device 11 searches the storage unit 103 for a voice warning message (eg, a first preliminary voice warning message) corresponding to the type of the transmitted disaster. A voice warning message (eg, a first voice warning message) including contents related to the type of disaster and the location of the disaster occurrence in the preliminary voice warning message is output to the voice message output unit 104 (S210). Accordingly, the first voice warning message is output to the outside through the voice message output unit 104.

At this time, since the first preliminary voice warning message includes content to refrain from accessing people, the first voice warning message may include the type of disaster, the location of the disaster, and the content of refraining from accessing vehicles and persons on the access route to the disaster occurrence location . The type of disaster and the location of the disaster occurrence of the first voice warning message may be determined by the content of the disaster notification request message transmitted from the situation room server 21.

Next, the control unit 102 of the access road display device 11 reads the collected user terminal identification information (eg, user terminal identification information related to the access road) stored in the storage unit 103 (S211), and The communication module 1011 is used to transmit it to the control room server 21 (S212).

The control room server 21 stores the user terminal identification information transmitted from the display device 11 on each access road through the communication unit in a storage unit corresponding to the display device 11 on the access road (S213), and then The disaster occurrence notification message along with the user terminal identification information is transmitted to each communication company device 31-3m (S214).

In this case, the disaster occurrence notification message may include a disaster type, disaster location information (eg, address of a disaster occurrence location) and a map, and a disaster situation message (eg, a first disaster situation message).

In this case, the first disaster situation message may include content about refraining from entering a vehicle to a disaster-related vehicle in order to quickly enter a disaster-related vehicle and requesting a rapid movement of a vehicle located at the disaster-occurring location.

In addition, the map may be obtained by using map data stored in the map database 23 as a map of the location of the disaster.

In this way, when a disaster notification message is transmitted from the control room device 20, the communication company server 311-3m1 of each communication company device 31-3m identifies the user terminal using its member information database 312-3m2. It is determined whether a member corresponding to the information exists (215), and if a member corresponding to the user terminal identification information exists, a phone number corresponding to the member, that is, a phone call of the user terminal 41-4p given the user terminal identification information The number is searched (S216).

Then, each communication company server 31-3m transmits the disaster occurrence notification message transmitted from the control room server 21 to the searched phone number using a message (SMS) server (not shown) (S217).

At this time, the first disaster situation message may be already stored in the storage unit of the communication company server, and in this case, the disaster occurrence notification message does not include the first disaster situation message. Accordingly, each communication service provider server 311-3m1 reads the first disaster situation message stored in the storage unit and transmits the disaster occurrence notification message to the searched phone number.

Accordingly, the user terminal having the searched corresponding phone number, that is, the access road user terminal 31 outputs the transmitted disaster occurrence notification message (S218), and the user of the access road user terminal 31 checks the disaster occurrence notification message. Make it possible.

In addition, through the transmitted message, the user can know the type of disaster and the location of the disaster, and can wisely determine the current action to be taken through the content of the first disaster situation message. Therefore, the vehicle located on the access path to the disaster occurrence place and the people around it quickly move to a safe place so as not to interfere with the entry operation of the disaster-related vehicle.

As a result, the time to enter the disaster-related vehicle to the disaster occurrence location is greatly shortened, and the risk of vehicle damage or personal injury upon entry is greatly reduced.

By this operation, when a disaster-related vehicle dispatched from a disaster-related agency and a disaster-related personnel arrive to the disaster-related location and suppress the disaster that occurred, the person in charge of the situation room sends the vehicle and the person to the location of the disaster to the situation room server 21. A signal for requesting restraint of access (eg, an access restraint request signal) is input (S219).

In this way, when the access control request signal is input, the control unit of the control room server 21 is a disaster situation display device located within a predetermined range centering on the disaster occurrence location determined by the disaster location information stored in the storage unit ( 11-1n) is searched to select a plurality of disaster location display devices (S220).

Then, the control unit of the control room server 21 transmits a driving end message to the display device 11 on each access road currently operating by using the information stored in the storage unit (S221).

Accordingly, the display device 11 on the access road stops the operation of the voice message output unit 104 and the indicator light 105 by the driving end message transmitted from the control room server 21, so that the voice message output unit 104 The output of the first voice warning message outputted to is stopped and the indicator 105 is turned off (S222).

Next, the control unit of the control room server 21 transmits an access control request message to each selected disaster location display device 12 (S223).

In this case, the access prohibition request message may include at least one of a method of driving a disaster notification unit, a type of a disaster, and information on a location of a disaster, and may include other information or data.

Therefore, when the access control request message is transmitted, the control unit 102 of each disaster location display device 12 drives the corresponding indicator 105 to the corresponding state (eg, the second state) (S224), and Voice in which a voice warning message corresponding to the type (for example, a second preliminary voice warning message) is searched in the storage unit 103, and the content related to the type of disaster and the location of the disaster is included in the searched second preliminary voice warning message A warning message (eg, a second voice warning message) is output to the voice message output unit 104 (S225).

At this time, the second state of each indicator 105 is driven to blink immediately from the time when the access control request message is transmitted, and even in this case, the lighting time and the light-off time have already been determined.

In addition, since the second preliminary voice warning message includes contents of refraining access to the disaster occurrence location, the second voice warning message may include the type of disaster, the location of the disaster, and contents of refraining access to the disaster occurrence location. And the location of the disaster occurrence may be determined by the content of the disaster control request message transmitted from the control room server 21.

Accordingly, the indicators 105 of all the searched disaster location display devices are simultaneously lit and flashed simultaneously, so that the area where the indicators 105 of the disaster location display device blink is the current disaster occurrence area. Is displayed to the outside, and the voice message output unit 104 periodically outputs a second warning voice message.

For this reason, drivers of vehicles located near the disaster site display device 12 or people around them recognize that they are located near the disaster site, and quickly evacuate to a safe place with the vehicle and access the disaster site. You will refrain from doing it.

Then, the control unit 102 of the disaster site display device 12 transmits the user terminal identification information stored in the storage unit 103 according to the transmission of the access control request message (for example, user terminal identification information related to the disaster site). Is read and transmitted to the control room server 21 using the control room communication module 1011 (S226, S227).

For this reason, the control unit of the control room server 21 stores the user terminal identification information transmitted from the disaster location display device in the storage unit (S228), and then sends an access control notification message along with the transmitted user terminal identification information to each communication company device 31-3m) (S229). The communication company server 311-3m1 of each communication company device 31-3m stores the transmitted access control notification message in the storage unit.

At this time, the access control notification message includes at least one of a disaster type, disaster location information and map, and a disaster situation message (e.g., a second disaster situation message) that includes content to refrain from accessing the disaster location. It is not limited to information or data.

Therefore, the communication company server 311-3m1 of each communication company device 31-3n searches for user terminal identification information corresponding to its member by using the member information of the member information database 312-3m2 from what has already been described, The user terminal corresponding to the searched user terminal identification information, that is, the phone number of the disaster location user terminal 42 is searched (S230, S231).

Then, the communication company server 311-3m1 transmits a notification message to refrain from accessing each disaster location user terminal 42 corresponding to the corresponding phone number using a message server, etc., and accesses the disaster location user terminal 42 The self-control notification message can be output (S232, S233).

Since the second disaster situation message may also be already stored in the storage unit of the communication service company server 311-3m1, in this case, the access control notification message does not include the second disaster situation message. Accordingly, each communication service provider server 311-3m1 transmits a second disaster situation message stored in the storage unit together with an access control notification message to the searched phone number.

Accordingly, the user of the disaster location user terminal 42 checks the content of the message output to the user terminal, and uses the current location information and a map of the disaster to identify the location of the disaster. If it is located adjacent to the occurrence site, evacuate to a stable place unrelated to the occurrence of a disaster to prevent damage to vehicles or people.

In addition, even if not located adjacent to the disaster location, the user of the disaster location user terminal 42 refrains from entering the disaster location so as not to increase the degree of congestion of the disaster location.

When the time passes and the generated disaster is extinguished, a signal for completing the disaster suppression is inputted to the situation room server 21 by the manager of the control room (S234).

Accordingly, the situation room server 21 transmits a drive end message to each of the currently operating disaster location display devices 12 (S235), and each disaster location display device 12 transmits a voice message output unit 104 and an indicator ( 105) can be stopped (S236).

Then, the user terminal identification information (i.e., user terminal identification information related to the disaster site) transmitted from the disaster location display device 12 stored in the storage unit is read, and the read disaster location-related user terminal identification information is provided. The termination notification message is transmitted to each communication company server 311-3m1 (S238).

In this case, the disaster termination notification message may include a disaster type, information on a location of a disaster, and information such as the occurrence of a disaster has been suppressed, but is not limited thereto, and at least one of them may be omitted or other information may be added.

Accordingly, each communication company server 311-3m1 searches for the phone number of the user terminal corresponding to the transmitted user terminal identification information, that is, the user terminal at the disaster location, and ends the disaster with the searched phone number. The notification message is transmitted (S239-S241).

For this reason, the user of each disaster location user terminal 42 to which the corresponding phone number is assigned uses the contents of the disaster end notification message output through their terminal to indicate that the disaster (eg, fire) that occurred in the corresponding place has been extinguished. By checking, it is known that the vehicle or the like can enter and access the disaster location (S242).

Referring to FIGS. 4A to 4D, the corresponding disaster situation display device (eg, 11) transmits the user terminal identification information collected by itself at the request of the control room server 21 to the control room server 21.

However, as another example, when a disaster notification request message is transmitted from the situation room server 21, the corresponding disaster situation display device may simultaneously transmit the user terminal identification information to the situation room server 21 and each communication company server 311-3m1. .

In this case, the communication unit 101 of each disaster situation display device 11-1n adds a communication company communication module that transmits to each communication company server 311-3m1 in addition to the control room communication module 1011 and the communication unit 1012 for information collection. It can be equipped with.

In this case, the operation of the disaster situation display system will be described with reference to FIG. 5.

The data flow diagram illustrated in FIG. 5 shows only steps in which different operations are performed as compared with FIGS. 4A to 4D, and steps in which the same operations are performed are omitted.

When a disaster notification request message is transmitted from the control room server 21 to the display device 11 on the access road through the same process as previously described with reference to FIGS. 4A and 4B, the display device 11 on each access road Reads the collected user terminal identification information stored in the storage unit 103 after operating the voice message output unit 104 and the indicator light 105 (S21-S211).

Then, the access road display device 11 simultaneously transmits the read user terminal identification information to the control room server 21 and each communication company server 311-3m1 (S31, S32).

For this reason, each communication company server 311-3m1 uses the member information stored in the corresponding member information database 312-3m2 to correspond to the user terminal identification information transmitted by the member's phone number, that is, the access road user terminal 41 Search the phone number of (S33, S34).

In addition, the control room server 21 stores the user terminal identification information transmitted from the user terminal 11 of each access road in a storage unit (S35), and then transmits a disaster notification message to each communication company server 311-3m1. (S36).

Therefore, each communication company server 311-3m1 transmits a disaster occurrence notification message to the searched phone number when a disaster occurrence notification message is transmitted from the control room server 21 (S37), and a disaster occurs to the user terminal 41 on each access road. By allowing a notification message to be output (S38), a rapid evacuation of the vehicle located on the entry route of the disaster-related vehicle is made.

In this case, since the time to search for the phone number of the user terminal 41 on the access road in the communication service company server 311-3m1 is further shortened, the timing of transmitting the disaster occurrence notification message to the user terminal 41 on each access road It gets faster.

6 shows another example when the user terminal identification information read by the access road display device 11 is simultaneously transmitted to the control room server 21 and each communication company server 311-3m1.

6 also shows only steps in which different operations are performed as compared with FIGS. 4A to 4D, and steps in which the same operations are performed are omitted.

Referring to FIG. 6, according to a disaster notification request message applied from the control room server 21, the display device 11 on each access road operates the voice message output unit 104 and the indicator light 105 and then stores it. After reading the collected user terminal identification information stored in the unit 103, the display device 11 on each access road transmits the read user terminal identification information to the control room server 21 and each communication company server 311-3m1. At the same time (S41, S32).

Therefore, as described with reference to FIG. 5, each telecommunication company server 311-3m1 uses the member information stored in the corresponding member information database 312-3m2 to be used for the member corresponding to the user terminal identification information. The phone number, that is, the phone number of the access road user terminal 41 is searched (S43, S44). At this time, the phone number of the searched access road user terminal 41 is stored in the storage unit by the corresponding communication company server 311-3m1.

Then, a preliminary disaster occurrence notification message is transmitted to the searched phone number (S45), and a preliminary disaster occurrence notification message is output to the user terminal 41 of each access road (S46).

In this case, the preliminary disaster occurrence notification message is already stored in the storage unit of the communication company server 311-3m1, and may include a content that a disaster has occurred in the vicinity of the current location.

For this reason, the user terminal 41 on the access road that received the preliminary disaster occurrence notification message does not know the exact location of the disaster and the type of disaster, but quickly recognizes the situation where the disaster has occurred, so it is necessary to prepare accordingly. You will be able to.

In addition, the control room server 21 stores the user terminal identification information transmitted from the user terminal 11 on each access road in the storage unit (S47), and then transmits a disaster notification message to each communication company server 311-3m1. (S48).

Therefore, each communication company server 311-3m1 reads the phone number of the access road user terminal stored in the storage unit when a disaster notification message is transmitted from the control room server 21, and the disaster occurrence notification message transmitted to each phone number. Is transmitted as a formal disaster occurrence notification message (S49).

Accordingly, each access road user terminal 41 outputs a disaster occurrence notification message (eg, a formal disaster occurrence notification message) including the type of disaster, information on the location of the disaster, and a map, and a first disaster situation message (S410). . Accordingly, the user of each access road user terminal 41 quickly moves his or her vehicle located on the access path to the disaster occurrence location according to the official disaster occurrence notification message output and moves to another safe place on the access route. do.

In this case, not only the effect of shortening the phone number search time of the user terminal 41 on the access road by the communication company server 311-3m1, but also the disaster occurrence situation to the user terminal 41-4p located in the entry route more quickly As a result, the evacuation of people and vehicles is made more quickly.

As a result, a disaster-related vehicle enters a disaster-related location more quickly, and the risk of damage to a vehicle located on the entry route and personal injury is greatly reduced.

As described above, due to the rapid movement of the vehicle parked and stopped at the fire location, the firefighter can easily and quickly enter the fire location, thereby increasing the fire entry efficiency and reducing human and property damage.

In this example, the plurality of disaster display devices 11-1n communicate with at least one of the control room device 20 and the communication company device 31-3m to function as a disaster road display device or a disaster situation display device when a disaster occurs. Therefore, the identification information of the user terminal 41-4p collected by the user is transmitted to the corresponding device 20, 31-3m, and the disaster occurrence situation or current disaster status is transmitted to the user terminal 41-4p collected by the user. Make it possible.

However, in addition to the occurrence of a disaster, such a plurality of disaster display devices 11-1n may be configured with external devices (for example, a fire department device, a traffic control server, a bus company or a taxi company server, etc.) through the operation shown in FIG. ), after collecting information (e.g., communication packet) transmitted from a terminal located within its communication range by communication with, and extracting the identification information of the corresponding terminal from the collected information, and periodically or at a request from the external device. Identification information can be transmitted every time. In this case, each disaster situation display device 11-1n functions as a terminal information collecting device.

Accordingly, each terminal information collecting device 11-1n is a communication unit that is located within a communication range and communicates with a terminal to receive information transmitted from a terminal located within the communication range, and is connected to the communication unit, and is input from the communication unit. A control unit for extracting the identification information of the terminal from the information, and transmitting the extracted identification information to an external device through the communication unit, and a storage unit for storing the extracted identification information.

In addition, the external device determines a terminal located within the communication range of the terminal information collecting device 11-1n using the identification information transmitted from the terminal information collecting device 11-1n, and the state of the terminal (ie, At what point the terminal information collecting device 11-1n is located, a moving path, a current position, etc.] is determined.

Since identification information corresponding to each terminal is stored in the external device, it is possible to determine a terminal corresponding to the transmitted identification information among a plurality of terminals.

As described above, the control unit of each terminal information collection apparatus may store only terminal information collected for a predetermined period of time due to the storage space of the storage unit and the like, and delete previously collected identification information.

In the embodiment of the present invention described above, a user searched by the disaster situation display device 11 through the situation room server 21 and the communication company server 311 or through the disaster situation display device 11 and the communication company server 311 A disaster occurrence notification message is transmitted to the terminal 41-4p.

However, unlike this, as another example, the disaster occurrence notification message may be directly transmitted from the disaster situation display device 11 to the corresponding user terminal 41-4p.

To this end, the disaster situation display device 11 uses the communication company server 311 to the user terminal 41-4p located within the communication range through the communication technology of Wi-Fi or Bluetooth of the communication module 102 for collecting information. Contents set by the push notification function, that is, disaster occurrence notification messages, are randomly transmitted using a personal area network (PAN) rather than a text service (SMS).

At this time, the disaster occurrence notification message is already stored in the storage unit 103 of the disaster situation display device 11.

Accordingly, when a disaster alarm request message is transmitted from the control room server 21, the control unit 102 reads the disaster occurrence notification message stored in the storage unit 103, and, as described above, the Wi-Fi communication method using a personal communication network. Or, it is randomly transmitted to the user terminals 41-4p located within the communication range by using the Bluetooth communication method.

In this case, since a disaster notification message is directly transmitted to the user terminal 41-4p without passing through a separate communication company server 311, a rapid disaster notification operation can be performed.

In the above, embodiments of the disaster situation display system and control method thereof according to the present invention have been described. The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations are possible from the perspective of those of ordinary skill in the field to which the present invention pertains.
