  However, in the technique described in Patent Document 1, the shortest guidance distance is specified by excluding the disaster occurrence area, but there is room for improvement because the state of the guidance route is not considered.

  Further, in the technique described in Patent Document 2, since the evacuation direction is guided in the direction opposite to the direction of smoke generation, there is room for improvement in the selection of the evacuation route.

  In the technique described in Patent Document 3, the shortest guidance route is obtained by weighting with a failure coefficient indicating the degree of obstacle in the passage. However, in obtaining the evacuation route, the degree of obstacle in the passage is taken into consideration. However, there is room for improvement because the capacity of the evacuation route and the distance to the disaster location are not considered.

  The present invention has been made in consideration of the above facts, and has an object to comprehensively determine the state of an evacuation route and to select an evacuation route for safely and surely guiding a building facility user. To do.

  In order to achieve the above object, the evacuation guidance system according to claim 1, the location information including the distance of each section when the facility information indicating the building facility provided with the evacuation exit is divided into a plurality of rectangular sections, Storage means for storing map information in which attribute information of each section including the evacuation capacity of the section and the flatness of the floor surface of each section is added to the facility information, detection means for detecting the occurrence of a disaster, and the detection means Search means for searching a plurality of evacuation routes starting from each section to the section having the evacuation exit based on the map information stored in the storage means when occurrence of a disaster is detected by A predetermined coefficient for each of the distance from the section to the section where the occurrence of the disaster is detected, the distance from the starting point to the section having the evacuation exit, the evacuation capacity of each section, and the flatness of the floor surface of each section; The memory On the basis of the attribute information stored in the search means, a calculation means for calculating a route state value representing a safety state for each evacuation route searched by the search means, and the route state value calculated by the calculation means And a selection means for selecting an optimal evacuation route based on the above.

  According to the first aspect of the present invention, the storage means includes position information including the distance of each section obtained by dividing the building facility into a plurality of rectangular sections, the evacuation capacity of each section, and the flatness of the floor surface of each section. Map information to which attribute information of each section including is added is stored.

  The detection means detects the occurrence of a disaster. For example, a fire is detected by a fire detection sensor that detects a fire, an earthquake is detected by a seismometer, an inundation sensor detects inundation, a disaster (fire, earthquake) , Disasters, floods, etc.) can be detected. The detection means may detect the occurrence of at least one disaster such as fire, earthquake, disturbance, and flood.

  In the search means, when a disaster is detected by the detection means, a plurality of evacuation routes from each section to the section having the evacuation exit are searched based on the map information stored in the storage means.

  In addition, the calculating means calculates the distance from the predetermined section to the section where the occurrence of the disaster is detected (for example, the section closest to the section where the disaster occurred among the sections included in each searched evacuation route, The distance to the detected section, the average distance from each section included in each searched evacuation route to the section where the occurrence of the disaster was detected, etc.), the distance from the start point to the section having the evacuation exit, A route state representing the safety state of the evacuation route searched by the search means based on the predetermined coefficient for each of the evacuation capacity and the flatness of the floor surface of each section and the attribute information stored in the storage means A value is calculated. That is, since the position information of the section is stored as attribute information in the storage means, the distance from the predetermined section to the section where the occurrence of the disaster is detected from the position information, and the distance from the start point to the section having the evacuation exit Since the storage means stores the evacuation capacity of the section (for example, passage width, etc.) and the flatness of the section as attribute information, the evacuation capacity of the section and the flatness of the section can be obtained, A route state value representing a comprehensive state of the evacuation route can be calculated by converting the coefficient into a coefficient.

  Then, the selection unit selects an optimum evacuation route based on the route state value calculated by the calculation unit. That is, since an evacuation route is selected by comprehensively judging the state of the evacuation route using a route state value considering the distance and safety of the evacuation route, an optimum evacuation route can be selected. Accordingly, it is possible to comprehensively determine the state of the evacuation route and select an evacuation route for safely and reliably guiding the building facility user.

It is possible to select an evacuation route that comprehensively determines the state of the. The selection of the shortest route may be performed by selecting a route having a maximum calculated route state value, or by obtaining a route state value having a predetermined value or more as a shortest route. The selecting means may select an evacuation route by excluding an evacuation route whose route state value is equal to or less than a predetermined threshold. As a result, an inappropriate evacuation route can be excluded.

  The coefficient is a coefficient used to calculate the route state value indicating the safety state of the evacuation route, and decreases as the distance from the predetermined section to the section where the occurrence of the disaster is detected increases. A predetermined value may be applied such that the distance to the section having the mouth becomes smaller, the smaller the evacuation capacity of each section becomes, and the smaller the flatness of each section becomes. In this case, the selection means can select an optimum evacuation route by selecting a route having a small route state value.

  According to a fourth aspect of the present invention, there is provided a display means for displaying an evacuation route provided in a building facility, and a control for controlling the display means to represent the evacuation route selected by the selection means. And a notifying means for notifying disaster information corresponding to the disaster state detected by the detecting means, provided in the building facility, wherein the storage means detects the disaster state detected by the detecting means The notification contents corresponding to the predetermined disaster level and emergency level are further stored, and the notification means reads out the notification contents corresponding to the disaster detected by the detection means from the storage means and notifies them. It may be. In other words, by further providing a display means and a control means, it is possible to comprehensively determine the state of the evacuation route, guide the building facility user to a safe and reliable evacuation route, further comprising a notification means, Corresponding to the predetermined disaster level and emergency level of the detected disaster by further storing the notification contents by the notification means corresponding to the predetermined disaster level and emergency level of the disaster detected by the detection means by the storage means It is possible to notify the contents that have been performed.

  9A and 9B show an example of a display device provided in, for example, a T-shaped passage. 9A and 9B, a plurality of LED light sources are arranged in a T shape. And the example which shows the direction of an evacuation route is shown by controlling lighting and light extinction of an LED light source so that light may move according to an evacuation route. FIG. 9B shows, as an example, a blinking state of the LED light source when the evacuation route is from the left to the bottom of the page.

  Further, as shown in FIG. 9C, LED light sources arranged in a T shape may be arranged in a plurality of rows. In this case, the display corresponding to the disaster level or the emergency level can be performed by changing the numerical value of the above-mentioned level correspondence map, that is, the number of the LED light source columns blinking according to the disaster level or the emergency level. Moreover, the light emission color of the LED light source may be changed to display according to the disaster level or emergency level.

  By the way, in the evacuation guidance system 10 according to the present embodiment, when a disaster occurs, the evacuation route for evacuating safely by avoiding the disaster occurrence section is searched. Searching for a route may not be safe depending on the state of the evacuation route. For example, when the passage width of the evacuation route is narrow, or when there are stairs or steps in the passage of the evacuation route, the evacuation route that avoids the narrow passage or stairs or steps is safer and more reliable Evacuation is considered possible.

  Therefore, in the present embodiment, not only searching for the shortest evacuation route, but also calculating a route state value for comprehensively determining the state of the evacuation route, and based on the calculated route state value, it is safe and reliable. Evacuation routes that can be evacuated are selected.

  The route state value is calculated by, for example, deriving each coefficient for all searched evacuation routes using the coefficient map shown in FIGS. Then, the cumulative sum of the coefficients is calculated as a route state value representing the state of the evacuation route. In other words, by calculating the route state value considering the distance and safety of the evacuation route, the state of the partition of different events is treated as the same event by expressing it as a coefficient, and the state of the partition, that is, the state of the evacuation route is comprehensively calculated. Can be evaluated.

  More specifically, the disaster section distance coefficient is A, the evacuation exit section distance coefficient is B, the evacuation capacity coefficient is C, the section flatness coefficient is D, and the coefficients representing the characteristics of each facility for each element are W1 to W4. , For the evacuation route of interest, the distance to the disaster-occurring division, the distance to the division with the evacuation exit, the smallest evacuation capacity among the divisions included in the evacuation route, and the worst flatness among the divisions included in the evacuation route Is appropriately calculated from the attribute information stored in the HDD 38 and converted into a coefficient using the coefficient map of FIG. And the state of a division can be judged by calculating | requiring a route state value with the following (1) Formula. As a determination method, a route state value that is not suitable as an evacuation route is set in advance as a threshold value, and an evacuation route that can be evacuated safely, reliably and quickly by eliminating an evacuation route whose route state value is equal to or less than the threshold value Can be explored. At this time, the evacuation route can be eliminated step by step by gradually increasing the threshold value.

Route state value = W1 × A + W2 × B + W3 × C + W4 × D (1)

In addition, about W1-W4, the route state value corresponding to various facilities is computable by setting according to the facility to apply.

  Next, an evacuation guidance program, an evacuation route search program, and an evacuation route display program executed by the evacuation guidance computer 30 stored in the HDD 38 will be sequentially described.

  FIG. 10 is a flowchart showing an example of the processing flow of the evacuation guidance program executed by the evacuation guidance computer 30 of the evacuation guidance system according to the embodiment of the present invention.

  When the evacuation guidance program is activated by the evacuation guidance computer 30, first, in step 100, disaster monitoring is started. That is, detection of the fire detection sensor 48, seismic intensity meter 50, and inundation sensor 52, photographing of the camera 54, and the like are started, and the process proceeds to step 102.

  In step 102, it is determined by the evacuation guidance computer 30 whether a disaster has been detected. This determination may be made by, for example, determining whether a fire or smoke has been detected by the fire detection sensor 48, determining whether an earthquake has been detected by the seismic intensity meter 50, or whether inundation has been detected by the inundation sensor 52. Whether or not a collapse due to an earthquake or a collapse of an article installed in the facility is detected from the difference image between the image captured by the camera 54 and a predetermined reference image, or the camera 54 The security officer monitors the captured images to determine whether or not information relating to the occurrence of a disaster has been input via the keyboard 40, or whether or not information relating to an earthquake or flood has been received from the external network 56 If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process proceeds to step 114.

  In step 104, it is determined by the evacuation guidance computer 30 whether or not the disaster occurrence section has already been registered. In this determination, it is determined whether or not the determination in step 102 has already been affirmed and the disaster occurrence section has been registered. If the determination is negative, the process proceeds to step 106, and if the determination is affirmative, step 108 is performed. Migrate to

  In step 106, the section corresponding to the disaster detected by the fire detection sensor 48, seismometer 50, inundation sensor 52, camera 54, etc. is registered in the RAM 34 etc. and the process proceeds to step 110.

  In step 108, since the disaster occurrence zone has already been registered, the disaster occurrence zone registered in the RAM 34 is updated, and when the evacuation route is searched, the updated disaster occurrence zone is considered. The searched evacuation route is reset to search for an evacuation route, and the process proceeds to step 110.

  In step 110, the evacuation route search process is performed by the evacuation guidance computer 30, and the process proceeds to step 112. In the evacuation route search process, an evacuation route search is performed by starting the evacuation route search program.

  Here, the evacuation route search program will be described in detail. FIG. 11 is a flowchart showing an example of the processing flow of the evacuation route search program executed by the evacuation guidance computer 30 of the evacuation guidance system according to the embodiment of the present invention.

  When the evacuation route search program is activated, in step 200, a predetermined section is set as the evacuation route start point, and the process proceeds to step 202. That is, one of the sections divided into a plurality of rectangular sections of the map information is set as a noticed evacuation route start point. In the present embodiment, a rectangular section having an attribute “a” is excluded from the evacuation route starting point because the section is a wall or a step.

  In step 202, usable entrance / exit information is acquired by the evacuation guidance computer 30. For example, information input by the security officer through the keyboard 40 from the monitoring result such as a captured image of the camera 54, the detection result of the lock detection sensor 64, and the like are acquired by the evacuation guidance computer 30.

  In step 204, all evacuation routes including sections excluding the adjacent section of the disaster occurrence section are searched by the evacuation guidance computer 30, and the process proceeds to step 206. That is, an evacuation route from a set evacuation route start point to a section including an available entrance / exit is searched from the map information and attribute information stored in the HDD 38. At this time, all evacuation routes including a section excluding a section adjacent to the section registered in the disaster occurrence section are searched. Note that the available entrances and exits are determined from the information acquired in step 202.

  In step 206, the route state value of the evacuation route is calculated by the evacuation guidance computer 30 for each evacuation route, and the process proceeds to step 208. That is, a route state value representing the state of the evacuation route searched for by the above-described equation (1) is calculated. Thereby, the state of the section included in the searched evacuation route can be determined.

  Subsequently, in step 208, the evacuation route whose calculated route state value is equal to or less than a predetermined threshold is excluded by the evacuation guidance computer 30, and the process proceeds to step 210. In other words, evacuation routes including narrow passages, evacuation routes including stairs and steps, evacuation routes that are relatively close to the disaster-occurring divisions, evacuation routes that have long distances to evacuation exits, etc. are excluded and are safe and reliable. Only an evacuation route that can evacuate (an evacuation route whose route state value is higher than others) is selected. Note that, depending on the threshold, it may be possible to eliminate all of them, so that the threshold may be gradually increased so that a predetermined number of evacuation routes remain.

  In step 210, the shortest evacuation route is selected from the evacuation routes not excluded, and the process proceeds to step 212. Although the shortest evacuation route is selected here, an evacuation route having a high route state value (for example, an evacuation route having the maximum route state value) may be selected.

  In step 212, it is determined by the evacuation guidance computer 30 whether or not the route search using all sections as the evacuation route start point has been completed. If the determination is negative, the process proceeds to step 214 to end the evacuation route search. Then, the process proceeds to step 112 in FIG.

  In step 214, the new section is set as the evacuation route start point, the process returns to step 200, and the above-described processing is repeated. When the route search using all the sections as the evacuation route start point is completed, the determination in step 212 is affirmed. Then, the process proceeds to step 112 in FIG.

  Then, when the process proceeds to step 112 in FIG. 10, the evacuation route display process is performed by the evacuation guidance computer 30 and the process proceeds to step 114. The evacuation route display process performs processing for displaying the evacuation route searched by the evacuation route search program when the evacuation route display program is activated.

  Here, the evacuation route display program will be described in detail. FIG. 12 is a flowchart showing an example of the processing flow of the evacuation route display program executed by the evacuation guidance computer 30 of the evacuation guidance system 10 according to the embodiment of the present invention.

  When the evacuation route display program is activated, in step 300, the disaster level and the emergency level are determined by the evacuation guidance computer 30, and the process proceeds to step 302. That is, the disaster level and the emergency level are determined from the disaster detected by various sensors and cameras, and the contents thereof.

  In step 302, values representing the notification contents and the notification level by the route display device 58, the monitor 60, and the speaker 62 are acquired by the evacuation guidance computer 30, and the process proceeds to step 304. That is, values representing the disaster level and the emergency level are acquired from the level correspondence map of FIG. 6 based on the detected disaster and its contents.

  In step 304, the route display device 58, the monitor 60, and the speaker 62 are controlled by the evacuation guidance computer 30 by a predetermined notification method according to the value acquired in step 302, and the process proceeds to step 118 in FIG. That is, the notification content stored in advance corresponding to the numerical value of the level correspondence map of FIG. 6 is selected from FIG. 7, and the display of the selected notification content and voice output are performed. In addition, display on the route display device 58 according to the disaster level and the emergency level is performed. When applying an example in which a plurality of LED light sources are arranged as the route display device 58, for example, by controlling the light emission of the LED light source so that the moving speed of the light looks faster as the disaster level and the emergency level are higher, Display according to the disaster level and emergency level can be performed. Further, by combining the color changes, it is possible to display both the disaster level and the emergency level.

  Then, when the process proceeds to step 118 in FIG. 10, the evacuation guidance computer 30 determines whether or not the system is stopped. The determination determines whether or not an instruction to stop the evacuation guidance program has been issued, or whether or not an instruction to stop the power supply of the evacuation guidance system 10 has been issued. The process described above is repeated, and the evacuation guidance program is terminated when the determination in step 118 is affirmed.

  As described above, in the evacuation guidance system 10 according to the present embodiment, when searching for an evacuation route when a disaster occurs, a route state value representing the state of the evacuation route is obtained to search for an optimum evacuation route, and the building facility Since the evacuation route is displayed on the route display device 58 provided therein, a safe and reliable evacuation route can be guided to the building facility user.

  More specifically, when determining the status of the sections included in the evacuation route, the distance from the start point to the disaster occurrence section, the distance from the start point to the evacuation exit section, the evacuation capacity of each section, and the flatness of each section are calculated. By expressing it as a coefficient, it is possible to select an optimum evacuation route because the evacuation route is selected by comprehensively judging the state of the evacuation route by evaluating as the same event.

  In addition, since evacuation routes are displayed according to the disaster level and emergency level, and disaster information is notified (display on the monitor 60 and audio output from the speaker 62), it is possible to provide the building facility users according to the disaster. Evacuation guidance is possible.

  Furthermore, since various disasters are detected by various sensors and cameras to search for an evacuation route, the evacuation route can be searched in real time according to the expansion of the disaster or the reduction of the disaster. Evacuation guidance is possible.

  In the above embodiment, an example in which an LED light source is used as the route display device 58 has been described. However, the present invention is not limited to this. For example, a display device that lights an arrow or the like may be applied. .

  Further, in the above embodiment, as an example of the predetermined coefficient, the distance to the disaster occurrence section, the distance from the start point to the section having the entrance, the evacuation capacity of each section, and the flatness of the floor surface of each section, As shown in FIG. 5, the distance from the starting point to the section having the entrance / exit increases as the distance to the disaster occurrence section increases, increases as the evacuation capacity of each section increases, and is flat in each section. As an example, a preset value that increases as the degree becomes flat is shown, but the present invention is not limited to this. For example, the distance from a predetermined section to a section where the occurrence of a disaster is detected decreases as the distance increases. The smaller the distance from the starting point to the section having the evacuation opening, the smaller the evacuation capacity of each section and the smaller the flatness of each section. It may be applied as previously set to be smaller enough that. In this case, an evacuation route whose route state value is equal to or greater than a predetermined threshold may be excluded. Further, by selecting an evacuation route having a small route state value (for example, an evacuation route having a minimum route state value), an optimum evacuation route can be selected.
