Description

[0001] The present invention relates to an indoor evacuation route guidance system and method,

The present invention relates to an indoor evacuation route guidance system and method, and more particularly, it relates to an improved method of constructing an existing emergency evacuation graph to reduce a route search operation time, And more particularly, to an indoor evacuation route guidance system and method.

Recently, large-scale facilities that many people can work in order to utilize limited land effectively have been increasing. In case of a disaster situation in such an indoor environment with a large-scale complex structure, many people may suffer damage. To prevent this, it is necessary to provide a precise evacuation route to the occupants who have fallen short of judgment in an urgent situation in an intuitive manner.

In this paper, a disaster evacuation graph is proposed by dividing indoor space into grid units in order to calculate evacuation routes when an indoor disaster occurs and to provide accurate travel route information to users.

In this disaster evacuation graph, a grid is superimposed on a two-dimensional space drawing, and the intersections of the grids expressed in the space where the human can move are formed as vertices of the graph, and the lines of the grid connecting the vertices are connected by an edge Create a grid graph. This topology configuration method has the advantage that the actual moving path of the user can be expressed precisely because the space is subdivided as the size of the grid is small, but a plurality of vertices may be unnecessarily constructed in one closed space. When the indoor space to be represented by the graph is large, the number of vertices becomes very large, which is disadvantageous in that it takes a long time to search the route.

Considering this point, a method of constructing the intersection points of interior space such as a room or a hall and the corridor connecting the space with the apex of the graph was studied. It consists of a closed space such as a room or a hole in a two-dimensional space drawing and a vertex at the intersection of the corridor connected to the space.

Such a configuration scheme is advantageous in that it does not constitute unnecessary vertices unlike a lattice graph because it displays a single closed space as a single vertex. However, in an indoor structure where a plurality of rooms are connected to one hallway, the hallway can be composed of a plurality of vertices in the graph. When the path is calculated, the hallway is connected to the stairs or the exit Taking into account the following points, the number of vertices on the corridor space increases the scale of the graph more than necessary.

Accordingly, there is a growing demand for an indoor evacuation route guidance system capable of overcoming the unreasonable point of the conventional evacuation route calculating method and constructing a disaster evacuation graph with a small number of vertexes to quickly search for the evacuation route.

FIG. 2 is a block diagram showing a main configuration of a map server according to the present invention, and FIG. 3 is a diagram illustrating an example of generating a disaster relief graph according to the present invention.

Referring to FIG. 1, a map server 100 according to the present invention includes a map information database 110, a disaster relief graph generation module 120, and a trunk attribute information database 130.

The map information database 110 stores architectural drawing image information of a specific building, unique ID information and coordinate information of a plurality of positioning beacons 400 installed in a specific building. In addition, trunk information and vertex coordinate information generated by the disaster relief graph generation module 120 are separately stored.

The disaster evacuation graph generation module 120 divides the location of the beacons 400 for each positioning beacon 400 into a predetermined area based on the coordinate information of each positioning beacon 400 stored in the map information database 110 The trunk and the vertex are set, and the disaster relief graph information is calculated.

The method of generating such a disaster evacuation graph will be described in detail with reference to FIG.

In FIG. 3A, a positioning beacon 400 is installed in a specific building. The unique ID number and coordinate information of the building drawing information and the positioning beacon 400 are stored in the map information database 110. Here, the positioning beacon 400 may be installed at all of the entrance, the stairs, the corridor, and the like. In the architectural drawing, there are eleven rooms, a central stairway that can be moved to another floor, and two entrances to the outside of the building. .

FIG. 3B shows a process of generating a disaster evacuation graph on the architectural drawing plane, in which an arbitrary area is divided in the architectural drawing centering on the plurality of positioning beacons 400 installed. This arbitrary area is constituted by a certain section for each beacon 400, and an arbitrary area is set around an entrance toward the passage in the building and the safety zone.

A plurality of vertexes are formed in each arbitrary region, and a single trunk line interconnecting the two vertices is formed in an arbitrary region.

That is, in the arbitrary area 1, a vertex b intersecting the arbitrary area 2 and the arbitrary area 3 is formed, and a vertex a is formed at the end of the corridor passage to generate the trunk line 1. In the arbitrary area 2, the vertex c is formed at the entrance and exit of the end of the corridor passage so that the trunk 2 is formed in the arbitrary area 2. [

As described above, arbitrary regions 1 to 6 are divided for each of the positioning beacons 1 to 6, vertices a to g are generated at the intersections or entrance / exit sides, and trunks 1 ~ 6 are formed.

3C, the generated vertex information and trunk information are separately stored in the map information database 110. The generated vertex information and trunk information are stored separately in a file, . Here, the vertex information stored in the database is the coordinate information of the vertices, and the trunk information includes the length information of the trunk.

The trunk attribute information database 130 stores trunk attribute information based on features in a certain area formed around each positioning beacon 400. [ The weights of the trunk line attribute values are determined according to the attribute information of the trunk line. The attributes of the trunk line for determining the weights of the trunk line attribute values include the degree of crowded people in the trunk line, A fixed value that is fixed as environmental information such as a distance between the beacon 400 for positioning, a width of the escape route, and a width of the exit opening width at all times depending on the position.

FIG. 4 is a block diagram showing a main configuration of a path server according to the present invention, and FIG. 5 is a block diagram showing a detailed configuration of an edge weight calculation module.

Referring to the drawings, the path server 200 according to the present invention receives trunk attribute information from the map server 100, calculates trunk attribute value weights, applies the calculated weights to a disaster relief graph, 300 in real time to calculate the evacuation route based on the disaster evacuation graph.

The path server 200 includes an edge weight calculation module 210, a user information reception module 220, a trunk attribute information update module 230, and an evasion path calculation module 240.

Here, the trunk weight calculation module 210 calculates a weight value to add an attribute according to the characteristics of the trunk to each trunk of the disaster evacuation graph generated by the map server 100. The trunk weight calculation module 210 includes a dense weight calculation block 211, a moving speed weight calculation block 212, a trunk distance decay calculation block 213 and an environment information weight calculation block 214.

The dense weight calculation block 211 calculates the number of users occupying an arbitrary area in the trunk based on the user location information in the trunk based on the user location information transmitted from the user terminal 300 to the path server 200 .

The movement speed weight calculation block 212 calculates the movement speed according to the change of the position information value of the user terminal 300 received in real time from the user terminal 300 as described above.

The dense weight calculating block 211 and the moving speed weight calculating block 212 calculate the density of indoor occupants and the average traveling speed in the trunk in real time in an arbitrary area in the trunk, .

The trunk distance calculation block 213 calculates a distance value to a neighboring trunk based on the distance information between neighboring positioning beacons 400. The environment information weight calculation block 214 calculates a trunk path distance The width of the corridor, the width and width of the entrance, and the location information of the fire-fighting and smoke-free facilities.

The trunk weight calculation module 210 updates the attribute based on the weight value calculated in the calculation block.

The user information receiving module 220 receives the personal information received from the user terminal 300 and the location information including the beacon 400 unique ID information.

The trunk attribute information update module 230 receives the disaster relief graph information from the map server 100 and calculates the attribute information of the specific trunk in the disaster relief graph information in consideration of the trunk attribute value weight in the trunk weight calculation module 210 .

This is because the passage in the wide hall differs from the passage in the narrow corridor, and the degree of escape is different depending on the degree of density in the space and the size of the doorway. Therefore, It is designed to reduce the average evacuation time of people or to create a path that prevents people from getting into a specific space.

The evacuation path calculating module 240 calculates the evacuation path based on the current location information of the specific user terminal 300 received by the user information receiving module 220 based on the disaster evacuation graph information for which the trunk property value has been updated, .

In order to search for an optimal evacuation path by changing the attribute value of the trunk and changing the value of the trunk, the trunk property value is changed according to the real time location information of the user terminal 300, In order to mitigate this load, trunk attribute information updated according to the weights of the trunk attribute values is stored in the buffer 250 at regular intervals, and the specific user terminal 300 received by the user information receiving module 220, With reference to the trunk property information stored in the buffer 250. [0064] FIG.

6 is a block diagram illustrating a main configuration of a user terminal according to the present invention.

Referring to the drawings, a user terminal 300 according to the present invention includes a user information transmission module 310, a guide image information generation module 320, and a display module 330.

FIG. 7 is a flowchart showing an overall procedure for generating and guiding an indoor evacuation route according to the present invention, and FIG. 8 is a view illustrating a method for guiding the evacuation route through each component of the indoor evacuation route guidance system according to the present invention .

Referring to the drawings, an indoor evacuation route guiding method according to the present invention is a method of guiding an indoor evacuation route based on architectural drawing information of a specific building previously stored in the map server 100 and location information of a plurality of positioning beacons 400 installed in a specific building (S710), receiving the disaster relief graph information from the path server 200, and updating the trunk attribute information by assigning each trunk attribute weight value to the beacon 400 (S720) (S730) of recognizing the location of the user terminal 300 from the location information of the user terminal 300 and transmitting the recognized location information to the path server 200 to calculate the evacuation path information based on the location information of the current user terminal 300, And transmitting the evacuation path information to the user terminal 300 and outputting the evacuation path guiding information on the screen (S740).

The disaster relief graph information generated by the map server 100 is provided to the path server 200, and the disaster relief graph information is updated in the path server 200. The user terminal 300 receives the building drawing information from the map server 100 and recognizes the location of the user terminal 300 using the beacon 400 for positioning.

That is, as shown in FIG. 8, when the beacon 1 recognizes the user terminal 300 and provides the beacon 1 ID information to the user terminal 300, the user terminal 300 transmits the beacon 1 ID information to the path server 200 And the path server 200 provides the trunk attribute weight value according to the location of the user terminal 300 to the specific trunk of the disaster evacuation graph to update the trunk attribute information.

The route server 200 calculates escape route information with the location of the user terminal 300 as a starting point through the updated route attribute information and provides the calculated escape route information to the user terminal 300.

The evacuation route information provided to the user terminal 300 is outputted as evacuation route guidance information on the screen of the user terminal 300 and is transmitted from the other positioning beacon 400 to the user terminal 300 The beacon 2 ID information recognized as the position of the beacon 2 is transmitted to the path server 200. In the path server 200, the weight of the beacon attribute value is changed by the change of the position of the user terminal 300, And recalculates the evacuation path information.

As described above, the trunk attribute value weight for updating the trunk attribute information is calculated by the dense weight calculation for calculating the number of people in the trunk based on the position information positioned through the positioning beacon 400 in the user terminal 300 And a movement speed weight calculation value for calculating a movement speed according to the movement of the position of the user terminal 300.

In addition, the trunk line attribute value weight is calculated based on the distance information between neighboring beacons 400 for positioning, the trunk line distance for calculating the distance value to the neighboring trunk is calculated based on the tooth cavity calculation value, the width of the escape route, And an environmental information weight value calculation value for calculating an environmental information value based on at least one of information of the fire-fighting equipment and the smoke-free equipment location, so as to provide a more efficient evacuation route to the user terminal 300. [

Furthermore, the disaster evacuation graph according to the present invention is a disaster evacuation graph according to the present invention, which divides an arbitrary area into beacons for each positioning provided for a plurality of buildings in a building, and determines each arbitrary area as an apex The beacon coordinate information of the arbitrary area, the coordinate information of each vertex generated in the arbitrary area, and the trunk information are managed in the database, and the position of the user terminal 300 , Only the weight of the trunk attribute value of the trunk in the arbitrary area where the user terminal 300 is located is updated again to speed up the computation speed when the weighted weight calculation value or the moving speed weight calculation value is changed.

That is, in the conventional graph construction method, arbitrary area spaces such as passages which are unnecessary for route representation are each formed as vertices, and when the position of the user terminal 300 is changed as described above, However, the disaster evacuation graph according to the present invention reduces the scale of the graph so that the evacuation passage area is formed only by the trunk line, and changes the attribute of the trunk line only to shorten the path search time.

The coordinate information and the vertex information on the path are matched with each other to generate a path image (B) having a line-shaped truncated line for each vertex (S920).

The generated path image B is superimposed on the construction drawing image A to generate the evacuation path output image C in operation S930. The evacuation path output image C thus generated is output on the screen of the user terminal 300 so that the user can confirm it (S940).
