3 is a flowchart illustrating a method of setting nodes in spatial information in a fire evacuation resource device according to an embodiment of the present invention.

4A to 4F are diagrams illustrating that nodes are set in spatial information.

3 and 4, the node setting module 210 extracts spatial information from the database 260 (S301). In addition, the node setting module 210 checks an independent space separated by a wall from the extracted spatial information. The independent space may be a space divided into a room, a conference room, a material room, a copy room, a restaurant, and a corridor.

Subsequently, the node setting module 210 sets each reference node as the center point of each independent space, sets the entrance node at the point where the entrance door is located, and sets the point where the window is located as a window node that can be selectively passed (S305). ). Specifically, the node setting module 210 may set the reference node for each independent space by using the center point of the independent space as a reference node. In addition, the node setting module 210 sets a door that can be accessed from the spatial information as an entrance node, and sets a window temporarily accessible as a door when evacuating as a window node. Here, a window that can be temporarily used as an entrance door when evacuating and is set as a window node means a window that is located between the independent space and the independent space, can be opened and closed, and has a predetermined size through which a user can pass.

4A is a diagram illustrating spatial information, divided into a total of 11 independent spaces, and a plurality of entrance doors and windows are arranged in the space.

4B illustrates a state in which a reference node, an entrance node, and a window node are respectively set in the spatial information of FIG. 4A. Referring to FIG. 4B, the node setting module 210 sets a point located at a center point in each spatial information as a reference node 41-N, and sets a point where an entrance door is located as the entrance node 42-1. In FIG. 4B, reference numeral 41-N is illustrated as a reference node set in an independent space, and as a result, the number of reference nodes increases according to the number of independent spaces. In addition, in FIG. 4B, reference numeral 42-N is illustrated as an entrance node set according to the position of the entrance door. In addition, reference numeral 43-N in FIG. 4B exemplifies a window node 43-N set for a window that can be temporarily used as an entrance door.

When the setting of the reference node, the entrance node, and the window node is completed, the node setting module 210 matches and stores the set reference nodes and entrance nodes with spatial information of the database 260.

Next, the node setting module 210 checks the location where each fire detection sensor is installed in the database 260. In addition, the node setting module 210 sets a plurality of sensor nodes in the spatial information so that the sensor nodes are arranged in the spatial information in correspondence with the installation location of the fire detection sensor 300, and spaces the plurality of sensor nodes thus set. The information is matched and stored in the database 260 (S307). 4C illustrates a state in which sensor nodes 44-N are set in spatial information corresponding to the positions of the fire detection sensors 300.

Subsequently, the node setting module 210 sets a plurality of virtual nodes used in an emergency from spatial information, groups the plurality of virtual nodes as a first group, and matches the nodes of the first group with spatial information. It is stored in the database 260 (S309). Specifically, the node setting module 210 forms a plurality of virtual lines spaced apart from the wall by a predetermined distance in an independent space and extending along the length direction of the wall, and then a plurality of virtual lines arranged at regular intervals in each virtual line. Virtual nodes are set in spatial information, and the plurality of virtual nodes are grouped into a first group.

4D is a diagram illustrating a plurality of virtual nodes corresponding to a first group. As shown in FIG. 4D, the node setting module 210 is spaced apart from the wall by a predetermined distance and forms a plurality of virtual lines L1 extending along the wall. In addition, the node setting module 210 sets a plurality of virtual nodes 45-N arranged at regular intervals along the virtual line L1 from spatial information, and removes the plurality of virtual nodes 45-N. Grouped into 1 group. The virtual nodes 45-N included in the first group are used to create an evacuation route in a state in which a view is not secured when a fire occurs.

Subsequently, the node setting module 210 sets a plurality of virtual nodes that are normally used in spatial information, groups the plurality of virtual nodes as a second group, and matches the virtual nodes of the second group with the spatial information. Then, it is stored in the database 260 (S311). Specifically, the node setting module 210 sets a virtual line equally dividing the horizontal space and the vertical space of the passage space into n (n is a natural number of 2 or more), and a plurality of virtual lines arranged at regular intervals along the virtual line. Virtual nodes are set in spatial information, and the plurality of virtual nodes are grouped into a second group.

4E is a diagram illustrating a plurality of virtual nodes corresponding to a second group. As shown in Figure 4e, the node setting module 210 forms a virtual line (L2) equally dividing the horizontal space of the passage and the vertical space of the passage by n, along the virtual line (L2) at regular intervals. A plurality of virtual nodes 46-N to be arranged are set in spatial information, and the plurality of virtual nodes 46-N are grouped as a second group. In FIG. 4E, a virtual line L2 dividing the passage space into two is illustrated, but a virtual line equally dividing the passage space into three or four equal portions or five or more may be formed from spatial information. The virtual nodes 46-N included in the second group are used to create a moving path during normal times when no fire has occurred.

Meanwhile, the node setting module 210 may remove the virtual nodes from the first group or the second group when there are fewer than a threshold number (eg, less than two) of virtual nodes in one independent space. In addition, if a small number of virtual nodes are set in a specific independent space, a moving route or an evacuation route can be sufficiently generated using only the sensor node and the reference node set in the corresponding space. The virtual node can be removed from the first group or the second group.

When node setting is completed in this way, a virtual node of a first group, a virtual node of a second group, a sensor node, a reference node, an entrance node, and a window node are set in the spatial information. 4F shows the spatial information, a virtual node 45-N of a first group, a virtual node 46-N of a second group, a reference node 41-N, an entrance node 42-N, and a window node 43. -N) exemplifies a set state.

Referring back to FIG. 2, the fire monitoring module 220 communicates with the fire detection sensor 300 and performs a function of checking whether a fire has occurred. When the fire monitoring module 220 receives the fire occurrence information from the fire detection sensor 300, it may check the identification information of the fire monitoring sensor 300. In addition, when a fire occurs, the fire monitoring module 220 requests the route generation module 250 to create an evacuation route.

The field of view analysis module 230 performs a function of determining whether a field of view can be secured at a point where a fire occurs. In one embodiment, the field of view analysis module 230 acquires an image from the CCTV camera 400 installed at the point where the fire occurs, analyzes the image to analyze whether smoke is generated near the point where the fire occurs, As a result of the analysis, when the area occupied by smoke in the image exceeds a predetermined threshold area, it may be determined that the view cannot be secured, and when the area occupied by the smoke is less than the critical area, it may be determined that the view is secured. . The field of view analysis module 230 may extract an object corresponding to smoke in the image and calculate the area of the smoke object by using known image analysis techniques such as RGB analysis, wavelet analysis, and machine learning analysis. . In another embodiment, the field of view analysis module 230 checks whether smoke is generated at the point of fire through a smoke detection sensor (not shown in the drawing), and confirms that no smoke is generated through the smoke detection sensor. If so, it can be determined that the field of view is secured. As another embodiment, the field of view analysis module 230 counts the fire time from the time when the fire is first detected, and then determines that the field of view is secured if the fire time is less than a preset threshold time, and the counted time is If the threshold time is exceeded, it may be determined that the fire has spread and the view cannot be secured.

The location measurement module 240 receives the radio wave strength for each access point measured at the current location from the user terminal 100, and records a radio wave pattern most similar to the radio wave strength for each access point received from the user terminal 100 The area is checked in the propagation map of the database 260, and the center point is determined as the user's position in the checked grid area.

The path generation module 250 provides a moving path to the user terminal 100 in normal times. At this time, the path generation module 250 connects one or more of the reference node, the entrance node, and the virtual nodes included in the second group to generate a moving path from the user's current location to the entrance node, and the user terminal 100 Provided as On the other hand, when a fire occurs, the path generation module 250 checks the location of the sensor node corresponding to the fire monitoring fine wire 300 detected by the fire in spatial information, and determines a danger radius previously set at the location of the sensor node. Set the danger zone to have. In addition, after recognizing the location of the user, the path generation module 250 checks whether or not the current field of view is secured in connection with the field of view analysis module 230. When the view is secured, the path generation module 250 generates an evacuation path having the shortest path from the user's location to the entrance node without passing through the danger area. On the other hand, when the view is not secured, the path generation module 250 is not included in the danger area among virtual nodes, reference nodes, sensor nodes, window nodes, and entrance nodes included in the first group. Unless nodes are selected, an evacuation route having a path from a user's location to an entrance node is created using the selected nodes, and virtual nodes included in the first group are included in the evacuation route.

5 is a flowchart illustrating a method of generating and providing an evacuation route in a fire evacuation support apparatus according to an embodiment of the present invention.

6A is a diagram illustrating a moving route, and FIGS. 6B and 6C are diagrams illustrating an evacuation route.

5 and 6, the path generation module 250 interlocks with the location measurement module 240 to measure the current location of the user, and the reference node, the entrance node, the sensor node, and the second group from the spatial information. By connecting one or more of the included virtual nodes, a moving path from the current location of the user to the entrance is generated and provided to the user terminal 100. When a movement path from the user terminal 100 to the entrance is requested, the path generation module 250 may generate the movement path and provide it to the user terminal 100.

Next, the fire monitoring module 220 communicates with the fire detection sensor 300 to continuously monitor whether a fire has occurred (S501).

When the fire monitoring module 220 receives fire occurrence information through the fire detection sensor 300 as a result of monitoring (ie, when a fire is detected), the fire monitoring module 220 checks the identification information of the fire detection sensor 300 that has detected the fire (S503). ). In addition, the fire monitoring module 220 requests the path generation module 250 to generate an evacuation path, and provides identification information of the fire detection sensor 300 that detects a fire to the path generation module 250.

Then, the path generation module 250 checks the identification information of the fire detection sensor 300 that detected the fire, and identifies the sensor node matched with the fire detection sensor 300 from the spatial information of the database 260 ( S505). Next, the path generation module 250 sets a danger area so that the location of the identified fire node becomes a central point, and has a danger radius previously set at the location of the sensor node (S507).

6B and 6C, when a fire is detected by the sensor node 44-4 of reference numeral 44-4, a danger area 61 having a predetermined danger radius is set in spatial information. When the risk area based on the center point of the sensor node 44-4 is formed beyond the wall, the path generation module 250 may adjust the risk area by removing some areas formed beyond the wall from the risk area.

Next, the path generation module 250 checks the location of the user through the location measurement module 240 (S509). The location measurement module 240 receives the radio wave strength of each access point measured at the current location of the user terminal 100 from the user terminal 100, and the radio wave strength of each access point received from the user terminal 100 The grid area recording the most similar propagation pattern can be checked in the propagation map of the database 260, and the center point of the checked grid area can be determined as the user's position.

Next, the path generation module 250 determines whether a view is secured around the current user location through the view analysis module 230 (S511). The field of view analysis module 230 acquires an image from the CCTV camera 400 installed at the point where the fire occurs, analyzes the image to analyze whether smoke is generated near the point where the fire occurs, and then analyzes the result of the analysis. When the area occupied by smoke exceeds a predetermined threshold area, it may be determined that the view cannot be secured, and when the area occupied by the smoke is less than the critical area, it may be determined that the view is secured. In another embodiment, the visual field analysis module 230 checks whether smoke is generated around the point where the fire has occurred through a smoke detection sensor (not shown in the drawing) installed around the user's location, and If confirmed, it can be determined that the field of view is secured. As another embodiment, the field of view analysis module 230 counts the fire time from the time when the fire is first detected, and then determines that the field of view is secured if the fire time is less than a preset threshold time, and the counted time is If the threshold time is exceeded, it may be determined that the fire has spread and the view cannot be secured.

If the path generation module 250 is in a state in which the field of view can be secured (Yes in step S513), the evacuation path having the shortest path from the user's location to the entrance without passing through the set danger area is generated, and this evacuation The path is provided to the user's terminal 100 (S515). In this case, the route generation module 250 may transmit to the user terminal 100 a kind of indoor map data in which a user's location and an evacuation route are displayed in spatial information. On the other hand, if the path generation module 250 is in a state in which it is impossible to secure a view (No in step S513), the risk area among virtual nodes, reference nodes, sensor nodes, entrance nodes, and window nodes included in the first group. Nodes that do not belong to are selected, and an evacuation route having a path from the user's location to the entrance node is generated using the selected nodes and provided to the user's terminal 100 (S517). In this case, the route generation module 250 generates the evacuation route so that some of the virtual nodes included in the first group are included in the evacuation route as an intermediate route.

6B illustrates that the shortest path from the user's location to the entrance is generated as an evacuation path as a view is secured. 6C illustrates that at the user's location as a view is not secured, a first group of virtual nodes (ie, virtual nodes formed along the wall) is included as an intermediate route. A user who is provided with an evacuation route as shown in FIG. 6C may reach the entrance while moving along the wall.

A reference node for a center point of an independent space, one or more sensor nodes, and an entrance node are set in the spatial information, and a plurality of virtual nodes of the first group and a plurality of virtual nodes of the second group are added to the spatial information. A node setting module to set;
A location measurement module for measuring a user's location;
A field of view analysis module that determines whether a field of view can be secured at the user's location; And
When a fire is detected by any one sensor node, a danger area having a predetermined size is set around the sensor node that detects the fire, and if it is possible to secure a view at the user's location, the nodes are used at the user's location. An evacuation route that has the shortest distance to the entrance node and does not pass through the danger area is created, and when it is impossible to secure a view at the user's location, at least one of the virtual nodes of the first group is included, and the danger area is Including a path generation module for generating an evacuation path from the user's location to the entrance node so as not to pass,
The plurality of virtual nodes of the first group are disposed at predetermined intervals in a plurality of virtual lines that are spaced apart from the wall by a predetermined distance and extend along the length direction of the wall,
The plurality of virtual nodes of the second group form a plurality of virtual lines dividing the passage, and the fire evacuation support device is arranged at regular intervals in the virtual lines. delete delete The method of claim 12,
The field of view analysis module,
A fire evacuation support apparatus, characterized in that it is determined that it is impossible to secure a view when an area occupied by smoke in the image exceeds a predetermined threshold area by acquiring an image around the user's location and analyzing the image. The method of claim 12,
The field of view analysis module,
After counting the fire time based on the time when the fire was first detected, if the fire time is less than the preset threshold time, it is determined that the field of view is secured, and if the counted time exceeds the threshold time, the fire spreads and Fire evacuation support device, characterized in that it is determined that is not secured. delete
