METHOD FOR ACTIVELY GUIDING EMERGENCY EVACUATION ROUTE

According to the present invention, a smart device carried by a person in the management area is informed of a dangerous area learned when an evacuation situation occurs, the smart device itself creates an evacuation route evading the dangerous area and guides the evacuation route along the evacuation route. By locating the additional dangerous areas along the route of the smart device and remotely supporting it to be shared by all smart devices in the management area, while minimizing the communication data volume and communication cycle of the smart device, solving the data traffic problem during evacuation situations, It is related to a method of guiding an active emergency evacuation route to safely evacuate everyone in the management area.

In the event of a fire in buildings such as apartments, officetels, buildings, shopping malls, multi-use facilities, exhibition halls, and event venues, it is necessary to promptly issue a fire alarm and guide the user to move along a safe evacuation route to prevent a human accident caused by the fire. It is the only way to reduce.

In recent years, when an emergency evacuation situation occurs, a technology for transmitting an evacuation situation and guiding an evacuation route using a smart device has been disclosed.

According to the registered patent No. 10-1185405 as a prior art, an application for installing a plurality of wireless repeaters in a structure, and outputting zone information, evacuation route information, and evacuation guidance message information of the evacuee location through a display window It is driven by the mobile terminal, and provides escape route information to the evacuee mobile terminal in the structure.

As another prior art, according to published patent No. 10-2017-0101657, the location of a user terminal entering a building is monitored, and an evacuation route based on the location of the user terminal and whether the communication infrastructure in the building is lost in an evacuation situation. Determine and provide to the user terminal.

However, the above-mentioned conventional technologies need to select an evacuation route that avoids the danger zone, and since Patent No. 10-2017-0101657 determines the danger zone based on whether or not the communication infrastructure in the building is lost, the actual danger zone is omitted. I can do it. For example, a dangerous area actually generated in a building due to fire or earthquake can be accurately determined by a person who judges that it is difficult to pass.

That is, as in Patent Publication No. 10-2017-0101657, it is determined that the communication infrastructure is damaged, or when it is detected by a sensor, it may be different from a case where a person directly determines. Eventually, there is a risk of misinformation of the hazardous area, which may lead to personal injury, and it may prevent you from evacuating quickly.

In addition, since a number of smart devices in the building need to be communicated with the server when an evacuation situation occurs, communication may not be smooth due to heavy traffic. In particular, such as large buildings and multi-use facilities.

In addition, since an application for guiding the evacuation route must be installed in advance on a smart device or connected to a server by a user in a building, it is inconvenient to use and may not be used because the evacuation route guidance system is not established. As a result, when an evacuation situation occurs, it may not be possible to prepare to safely evacuate everyone in the building.

In addition, it should be simple to guide the evacuation route. In other words, in an actual evacuation situation, even if accurate evacuation route information is transmitted in a complicated manner, it is determined that it is desirable to simply guide the evacuation direction because the evacuation route information may not be properly utilized.

The smart device 40 shown in FIG. 3 may be exemplified by a smart phone, a tablet PC, and the like, and only components necessary for carrying out the present invention are illustrated.

The active emergency evacuation route guidance system illustrated in FIGS. 1 to 3 is a wireless positioning infrastructure (10: 11, 12) distributed in a management area (1), and an entrance (entrance, entrance, 2) of the management area (1). It includes a tag 20 installed in), a smart device 40 entering the management area 1 and a server 30 that communicates with the smart device 40 through the communication network 3.

The wireless positioning infrastructure (10: 11, 12) is a communication infrastructure that allows the smart device 40 to know its location, as shown in the beacon 11 periodically transmitting a beacon signal, and within the management area It may be an AP (Access Point, 12) installed to be connected to the communication network (3).

The technology for identifying one's own position in the management area 1 using the wireless positioning infrastructure 10: 11 and 12 in the smart device 40 is a technique known in the art.

When describing an embodiment of the present invention, it is assumed that the beacon 11 is used.

The beacon 11 preferably transmits a beacon signal including a beacon ID at regular intervals, and is preferably distributedly distributed to receive a beacon signal anywhere in the target area 1. More preferably, the beacon 11 is distributed to receive the beacon signal and measure the position by a triangulation technique.

As will be described later, the beacon arrangement map indicating the location and beacon ID of the beacon 11 distributedly distributed in the target area 1 is stored in the DB of the server 30.

On the other hand, the beacon 11 is operating at low power, it is preferable to use a BLE beacon (Bluetooth Low Energy Beacon) that can operate for a long time while consuming the power of the built-in battery.

The tag 20 is provided at the entrance 2 of the management area 1 to provide an access environment for the App Store 5 for installing the evacuation guidance application 50 when tagging with the smart device 40. .

For example, the tag 20 is composed of a QR code, an NFC tag, and the like, but stores and stores an access address of the App Store 5 that can download the evacuation guidance application 50, so that the smart device 40 After tagging, read the access address, access the App Store 5 through the communication network 3, download the evacuation guidance application 50, and install and execute it on the smart device 40.

However, in the embodiment of the present invention, the smart device 40 also reads the ID of the tag 20 when reading the access address of the app store 5 from the tag 20.

Then, the evacuation guidance application 50 is executed on the smart device 40 and simultaneously accesses the server 30 through the communication network 3, and arranges evacuation route maps and beacons related to the management area 1 identified by the tag ID. Request the map, receive the evacuation route map and beacon arrangement map transmitted in response to the request from the server 30 and store it in the storage unit 47 of the smart device 40 to match the tag ID.

Accordingly, the smart device 40 entering the management area 1 is equipped with a readiness to guide the evacuation of the entrant safely when an evacuation situation occurs within the management area 1.

The smart device 40 and the evacuation guidance application 50 will be described with reference to FIG. 3.

As shown in FIG. 3, the smart device 40 includes a mobile communication module 42 for LTE wireless communication, a WiFi module 43 capable of communicating with a wireless access point in the management area 1, and a beacon 11 Bluetooth module 44 capable of receiving the beacon signal transmitted from, tagging means 45 capable of reading the stored information by tagging the tag 20, user UI 46 for touch input and screen output, It has a resource including a motion sensor 47 for detecting the motion and orientation of the smart device 40, and a storage unit 48 for storing data, and executes an application in the processor 41 to use resources. Can perform a function.

Here, the tagging means 45 is different depending on the type of the tag 20, for example, if the tag 20 is a QR code, an application that scans and recognizes an image, and the tag 20 is an NFC tag And become an NFC module.

The evacuation guidance application 50 installed in the smart device 40 includes a map management unit 51 for performing functions, a location identification unit 52, an evacuation route generation unit 53, an evacuation direction guidance unit 54, and It includes a route departure monitoring unit 55, is executed in the processor 41 immediately after being installed in the smart device 30, checks the stored map and selectively stores it, and within the management area 1, the server 30 ) Is executed in the background until the evacuation status notification message and the danger zone are transmitted, and is executed in the foreground from the time when the evacuation status notification message and the danger zone transmitted from the server 30 are received. .

Specifically, the map management unit 51 receives the tag ID when tagging the tag 20 while entering the management area 1, and stores the evacuation route map and the beacon arrangement map matched with the tag ID. If it is confirmed that it is in this storage unit 48, if not, the evacuation route map corresponding to the tag ID (or related to the management area) and the beacon arrangement map are downloaded from the server 30, and the storage unit 47 matches the tag ID. ). Of course, when the tag 20 is initially tagged, the evacuation guidance application 50 is installed, and the tag ID obtained by tagging is used.

That is, when the tag tag 20 is tagged when the smart device 40 passes through the entrance 2 again, the process of saving the map may be omitted, and the tag 20 may be entered and entered into another management area where the map is not stored. When tagging), since the new tag ID is confirmed, the corresponding evacuation route map and beacon arrangement map corresponding to the new tag ID are received and stored.

Of course, the smart device 40 in which the evacuation guidance application is installed, even if the tag 20 of any management area is tagged, the app installation process is omitted. However, the portable accessor of the smart device 40 will check whether or not the evacuation guidance application is executed in the tagging process and execute it if the execution is stopped.

On the other hand, the map management unit 51 in the process of downloading the map or omitting the download according to the tag ID stored in the storage unit 48, the phone number of the smart device 40 (that is, the access phone number) server ( 30), and notifies that the management area 1 has been entered.

Here, the evacuation route map is an electronic map showing passages through which people can move to safely evacuate. That is, the evacuation route map includes the entire travel area of the management area 1.

The evacuation route is a route to evacuate the danger zone from the location where the smart device 40 is located, and is obtained from the evacuation passage map according to the location of the danger zone and the location of the smart device 40.

The beacon arrangement map is an electronic map showing the location of each beacon 11 distributed in the management area 1 and the ID of the beacon 11.

If the AP 12 in the management area 1 is used as the wireless positioning infrastructure 10, a deployment map of the AP 12 in the management area 1 must also be prepared and utilized.

As such, the evacuation guidance application 50 can use the evacuation route map and the beacon arrangement map related to the management area 1, so that the smart device 40 is prepared to guide the evacuation route when an evacuation situation occurs. It is equipped.

After the smart device 40 passes through the entrance 2 and enters the management area 1, the evacuation guidance application 50 is executed in the background and then the evacuation situation is notified from the server 10 and the danger zone When receiving the location of, it is executed in the foreground, and activates the location identification unit 52, the evacuation route generation unit 53, the evacuation direction guide unit 54, and the route departure monitoring unit 55.

The location identification unit 52 searches for a beacon ID of a beacon signal transmitted and received from the beacon 11 in the beacon arrangement map to identify the location of the smart device 40. When identifying the position, the distance from the beacon 11 may be estimated according to the strength of the beacon signal to more accurately identify the position.

The evacuation route generation unit 53 matches the identified location and the received dangerous area to the evacuation route map, and starts at the identified position, avoids the received dangerous area and obtains an evacuation route that can escape.

The evacuation direction guide unit 54 determines the evacuation direction for moving along the evacuation route with the help of the motion sensor 47 and outputs it to the screen of the user UI 45. That is, since the orientation can be detected from the motion sensor 47, the evacuation direction can be determined and guided, and the entrant can move in the evacuation direction output to the smart device 40 and evacuate along the evacuation route.

Even while guiding the contrast direction, the position identification unit 52 continues to operate, real-time identifying the changed position, and periodically transmitting it to the server 30.

The route departure monitoring unit 55 is based on the movement and direction of the smart device 40 to be detected with the help of the motion sensor 47, and the location identified by the position identification unit 52, the smart device 40 Obtaining the moving path of, monitors whether the evacuation path is deviated.

If the evacuation route is deviated, the evacuation route is generated to add the evacuation route starting position, i.e., the evacuation route to the danger zone, to create an evacuation route that avoids the danger zone added by the evacuation route generation unit 53. And to guide the evacuation direction along the evacuation route modified by the evacuation direction guide unit 54.

Then, the route departure monitoring unit 55 notifies the server 30 of the added danger zone according to the departure location.

On the other hand, the danger zone added by the smart device 40 itself may be designated as an access person carrying the smart device 40 as described later with reference to FIG. 5.

The server 30 stores an evacuation route map and a beacon arrangement map classified for each management area 1, and furthermore, a database 31 provided for storing an access phone number (smart device phone number) and an evacuation passage A map support unit 32 that provides a map and a beacon arrangement map to the smart device 40 and receives and stores the phone number of the smart device 40, and an evacuation situation that receives the evacuation situation and the danger zone from the alarm means 4 It includes a reception unit 33, and a transmission unit 38 that delivers each smart device 40 in the management area 1 using an access phone number as soon as an evacuation situation and a danger zone are received.

That is, since the alert means 4 identifies the danger zone when an evacuation situation occurs, the evacuation situation has occurred, and the server 30 so that the server 30 knows where the identified danger zone is. It is linked with.

The object to receive the evacuation situation and the danger zone through the evacuation situation reception unit 33 is installed in the management area 1 as an alarm means 4 for emergency broadcasting, but is not limited thereto, and the evacuation situation and danger It is just a means to identify the zone. For example, as disclosed in Patent No. 10-1536876, a sensor that detects a danger zone may be used.

In addition, the server 30 transmits an evacuation status notification message indicating that an evacuation situation has occurred due to a cause in a certain management area 1 to all smart devices 40 in the management area 1, and also locates the danger zone. To propagate.

In addition to this, the server 30 includes a collection unit 34 for collecting the location of the smart device 40 and the dangerous area added by the smart device 40, and the dangerous device having the same number of smart devices 40 with a preset number or more. When adding, the risk zone selection unit 35 to determine the corresponding danger zone, the density calculation to calculate the density (or congestion) on the evacuation route according to the location of the smart device 40 in the management area 1 (36), and further comprises an alternative information generating unit 37 for generating alternative information that can be evacuated by avoiding the dense section and screening the smart device 40 toward the dense section, the danger zone selection unit 35 As soon as the danger zone is determined, the information is propagated to the smart devices 40 in the management area 1 to be mutually shared, and the alternative information generation unit 37 immediately generates the alternative information to the selected smart devices 40. Deliver Depending on the solution information to modify the evacuation route.

That is, the server 30 obtains a dangerous area not identified by the alarm means 4 through the smart device 40 carried by the entrant in the management area 1, and all smart devices in the management area 1 Make it possible for (40) to share, avoiding the shared danger zone and evacuating safely.

In addition, in order to prevent a plurality of users from being in danger due to the wrong movement path of some people, the danger zone estimating unit 35 occurs when the smart devices 40 deviating from the same location have more than a preset number. To, add the escape location to the danger zone. For example, if three or more people at the same location leave the evacuation route, the area is added as a danger area.

The denseness (or congestion) calculated by the denseness calculation unit 36 is satisfactory as long as it is an indicator of a stagnant section when the people carrying the smart devices 40 move along the evacuation route. For example, it may be determined according to the width of the evacuation route, the number of smart devices 40 for each section on the evacuation route, the increasing speed or the moving speed of the number of smart devices 40 for each section, and the like. However, since there is a possibility that the accessor may lose the smart device 40, it is desirable to exclude the smart device 40 that does not move beyond a predetermined threshold time from the calculation of the density.

As an embodiment, the alternative information generating unit 37 determines an area in which a density higher than a predetermined set reference value appears as an avoidance area, sets the avoidance area as alternative information, and selects the smart device 40 directed to the avoidance area. . In addition, the transmission unit 36 propagates the evasion zone to the selected smart devices 40, so that the smart device 40 guides the evacuation zone along the evacuation route in addition to the danger zone.

As another embodiment, the alternative information generating unit 37 may be a danger zone collected through the alarm means 4 and the smart device 40 and a avoidance zone obtained according to the density (or congestion) of the smart device 40. Generates an alternative route to avoid itself, and propagates the generated alternative route to the selected smart device 40. Accordingly, the smart device 40 guides to move along the evacuation route generated by itself, and when receiving the alternative route, guides to move along the alternative route. However, it is also possible to allow an access person carrying the smart device 40 to select a user UI whether to use an alternative route or a self-generated evacuation route.

4 is a flowchart of an active emergency evacuation route guidance method according to an embodiment of the present invention.

Since the method for guiding an active emergency evacuation route according to an embodiment of the present invention is made by the system described with reference to FIGS. 1 to 3, detailed overlapping description will be omitted and the present invention will be described to a clear understanding.

According to the active emergency evacuation route guidance method according to an embodiment of the present invention, the tag 20 provided in the entrance 2 of the management area 1 in the smart device 40 of the entrant entering the management area 1 Tagging starts from the preparation step (S10) where an app store access environment is provided.

In the preparation step (S10), by tagging the tag 20 in the smart device 40, an access point of the app store 5 capable of installing the evacuation guidance application and a tag ID assigned to the tag 20 are obtained. Thus, by using the App Store 5 access address, the evacuation guidance application can be installed (S11), and the evacuation guidance application is installed and simultaneously connected to the server 30, thereby evacuation route map corresponding to the tag ID And receiving and storing the beacon arrangement map from the server 30 (S12).

Accordingly, the smart device 40 is ready to cope with the evacuation situation.

If the evacuation guidance application is installed in the smart device 40, the installation process of the evacuation guidance application is omitted. However, if the evacuation guidance application is stopped, the entrant will call and execute the evacuation guidance application.

In addition, since the map management unit 51 of the evacuation guidance application first checks whether the evacuation route map and the beacon arrangement map corresponding to the tag ID are stored in the smart device 40, if not, requests to the server 30 After receiving and storing it to match the tag ID, if it is stored, the server 30 is not requested.

At this time, the evacuation guidance application sends the phone number of the smart device 40 to the server 30 whether or not the server 30 requests the evacuation route map and the beacon arrangement map. Accordingly, the server 30 may store and store phone numbers of the smart devices 40 that have entered the management area 1 for each management area 1.

Then, the smart device 40 is carried by the entrant with the evacuation guidance application running in the background, and enters the management area 1.

When the server 30 receives an evacuation situation and a dangerous area due to a fire or an earthquake through the evacuation situation reception unit 33 (S21), a message informing the evacuation situation and a dangerous area (S23) alert step (S20) To perform.

The alert step (S20) is a smart device 40 in the management area (1) where the evacuation situation occurred using a phone number to transmit a danger zone and evacuation status notification message.

The smart device 40 receiving the danger zone and evacuation status notification message operates the evacuation guidance application 50 in the foreground, and performs the guiding step S30 to evacuate the person who carried the smart device 40. Guide the direction of movement.

First, the location is identified with the help of the wireless positioning infrastructure 10 built in the management area 1, and the identified location and the received danger zone are applied to the evacuation route map, thereby avoiding the danger zone at the identified location. An evacuation route that can be evacuated is generated (S31).

In the embodiment of the present invention, since the wireless positioning infrastructure 10 is a beacon 11, the evacuation guidance application of the smart device 50 is a beacon signal that is transmitted and received from the surrounding beacon 11 and a stored beacon arrangement The location is identified based on the map.

Then, the generated evacuation route is guided to the user UI 46 (S32).

As described above, the location of the smart device 40 that is changed while guiding the evacuation route is periodically acquired and transmitted to the server 40, and the smart device 40 monitors whether the evacuation route deviates (S33), if the evacuation route When the departure, the departure location is added to the danger zone and the added departure location is transmitted to the server 30 (S34). In addition, according to the danger zone and the departure location received from the server 30, all added danger zones are avoided and an evacuation route capable of evacuation is generated (S35). At this time, it is guided to move along the generated evacuation route.

Referring to the screen configuration diagram of the user UI 46 illustrated in FIG. 5, a route change button 45b is provided to guide the evacuation direction to the direction indicator 45a and tap when changing the evacuation route.

That is, the smart device 40 determines the evacuation direction to move along the evacuation route by applying the position of the smart device 40 and the orientation or movement detected by the motion sensor 47, and guides the direction indicator 45a do.

The route change button 45b is a button to obtain an alternative route by tapping when there is another dangerous area in addition to the dangerous area transmitted from the server 30.

In other words, the accessor taps the route change button 45b if there is a danger zone while moving in the evacuation direction guided by the smart device 40. Then, the smart device 40 becomes a forward location close to the current location, but adds a location on the evacuation route to the danger zone, obtains an alternative route according to the addition of the danger zone, and guides the evacuation direction. Since the path change button 45b may be accidentally tapped, the path change button 45b may be double-taped. Of course, the added danger zone is delivered to the server 30.

However, in an evacuation situation, there may be no intention to tap the path change button 45b, and according to an embodiment of the present invention, an alternative path can be obtained by itself according to the movement path of the smart device 40.

That is, when the direction of movement deviates from the evacuation route, the anterior zone of the departure position is added as a danger zone, and the alternative route according to the received danger zone and the added danger zone is self-selected and replaced based on the evacuation route map. Guide the evacuation direction along the route.

Referring to the drawing illustrated in FIG. 6, the smart device 40 selects the optimal evacuation route L1 among the passages in the building by matching the dangerous area a1 to the evacuation route map, and then evacuating from the current location ( It is possible to guide the evacuation direction to move along L1).

While moving along the evacuation route L1, it is monitored whether the escape route L1 is deviated by acquiring the travel route through the motion sensor 47 or the beacon 11. If the escape route L1 is deviated, it is determined that there is a new danger zone a2 not included in the danger zone a1 received from the server 30 in front of the escape location S, and the alternative route ( L2) is generated on its own, and the evacuation direction is guided along the alternative route L2. That is, even if the shortest distance evacuation route is selected, the lane evacuation route may be selected if a danger zone is added.

And, by notifying the server 40 of the newly discovered danger zone a2, it is shared by being transmitted to other smart devices 40 by relaying the server 40 as described later.

On the other hand, the danger zone (a2) to be added has been described as the front position (or zone) of the departure position (S), but the danger zone (a2) can diffuse over time, so even if selected as the departure position (S) It can be regarded as obtaining the same result. Thus, the additional danger zone (a2) has been described as the exit position (S). Of course, the front position of the departure position may be determined as a position spaced apart by a predetermined distance determined in advance based on the moving direction.

Next, the server 30 propagates the dangerous area identified when the evacuation situation occurs to the smart devices 40 in the management area 1 to guide the evacuation even after the dangerous area sharing support step (S41) and the evacuation route distribution The remote support step (S40) including the support step (S42) is performed.

In the dangerous zone sharing support step (S41), when a smart zone 40 added by the smart devices 40 in the management area 1 is collected, when the number of smart devices 40 having more than a preset number adds the same zone as a dangerous zone , The corresponding danger zone is transmitted to another smart device 40, that is, the smart device 40 that has not added the corresponding danger zone, to be shared.

Accordingly, even if the smart device 40 in the management area 1 receives the dangerous area identified at the time of receiving the evacuation situation from the server 30 and determines and guides the evacuation route, it deviates from the evacuation route and creates the dangerous area. When adding, and when receiving the dangerous zone added by the other smart device 40 as a relay of the server 30, the evacuation route is modified to guide the modified evacuation route.

The evacuation route distribution support step (S42) collects the location of the smart device 40 transmitted from the smart device 40 in the management area 1, and calculates the density (or congestion) for each passage section on the evacuation route map. Then, when a section in which a density is higher than a predetermined set reference value occurs, the corresponding team is determined as an evasion zone and transmitted to the smart device 40.

That is, since the smart device 40 in the management area 1 avoids both the danger zone and the avoidance zone and creates an escape route that can escape, it is possible to guide the evacuation direction safely and quickly.

As a modified embodiment, the server 30 may generate an alternative route that avoids both the danger zone and the avoidance zone, and transmit it to the smart device 40. However, in order to reduce the amount of data to be transmitted, it is better to make the avoidance zone a smart device 40 capable of acquiring an evacuation route by itself.

On the other hand, when determining and propagating the evasion zone according to the density (or congestion), it is preferable to limit the smart devices 40 to be propagated to the smart devices 40 moving to the evasion zone.

Also, in the evacuation situation, since the smart device 40 may be lost by the entrant, the smart device 40 that does not move beyond a predetermined threshold time is excluded from the density calculation, and the density (or congestion) of the entrant is accurately calculated. It is desirable to do.
