FIG. 1 shows a plan layout of facilities such as shopping malls, department stores, underground malls, etc. where there are a plurality of stores or sales floors. Although only one floor is displayed here, the facility may be composed of a plurality of floors.

  As shown in FIG. 1, the guidance system using the double-sided display 10 of the present invention has the double-sided display 10 disposed at an appropriate position on the traffic path 30 in the facility, and is provided on the A and B sides of the double-sided display 10 described later. This is a guidance system that improves guidance efficiency to the destination 40 by displaying guidance information 20 corresponding to the positional relationship with the destination 40.

  FIG. 2 is a perspective view of the double-sided display 10 used in the guidance system of the present invention. The double-sided display 10 includes a box-shaped casing 1, a first display unit 2 and a second display unit 3 having display surfaces arranged on the front and back surfaces of the casing 1, and a circuit board 4.

  The first display unit 2 and the second display unit 3 are portions for displaying guidance information 20 for guiding a passerby in the facility to the destination 40. In the present embodiment, a TFT (Thin Film Transistor) substrate and Although it is realized by a liquid crystal display panel configured by enclosing liquid crystal between a CF (Color Filter) substrate, other types of display panels may be used.

  Hereinafter, of the display surface of the first display unit 2 and the display surface of the second display unit 3, the display surface that faces the destination direction as the traveling direction is referred to as A surface, and the display surface is opposite to the traveling direction. Is called the B side. In the guidance system of the present invention, as shown in FIG. 1, a double-sided display 10 is installed on a traffic path 30 so as to face a passerby who travels between A side and B side.

  The double-sided display 10 includes a circuit board 4 for generating guidance information 20 in the housing 1. The circuit board 4 includes a position sensor 5 such as a GPS (Global Positioning System), an orientation sensor 6 such as an electronic compass, A communication unit 7 that can communicate with an external device or another double-sided display 10, a memory 8 that stores various data, and a control unit 9 that controls the entire system are provided.

  FIG. 3 shows a display pattern of the guidance information 20 displayed on the A side or the B side of the double-sided display 10. In the guidance system using the double-sided display 10 of the present invention, since the destination 40 to be guided is different between the normal time and the emergency time, several display patterns of the guidance information 20 are prepared.

  In FIG. 3, (a) is the display pattern of the A surface displayed at normal time, and (b) is the display pattern of the B surface at normal time. Further, (c) is a display pattern of the A surface displayed in an emergency, and (d) is a display pattern of the B surface in an emergency. Each display pattern is composed of several display areas.

  As shown in FIGS. 3 (a) and 3 (b), in a normal state, a store in the facility is set as the destination 40, and an image of store product information is displayed and displayed in the display area A of the display pattern. In the area B, position information indicating the store name and the direction and distance of the store is displayed. For example, when guiding to one store using the A side and the B side of the double-sided display 10, the same image is displayed in the display area A on the A side and the B side, but the display area B on the A side and the B side. Then, it displays so that each guidance direction becomes opposite.

  In addition, as shown in FIGS. 3C and 3D, in the event of an emergency such as a fire, an emergency exit or evacuation site is set as the destination 40, and a message indicating an emergency is displayed and displayed in the display area A. In the area B, position information indicating the direction and distance of the emergency exit is displayed.

  In the guidance system using the double-sided display 10 of the present invention, even when the guidance system is normally guided to a store or the like, when an emergency occurs, the destination 40 is immediately changed to an emergency exit and priority is given to evacuation guidance. To do it.

  As described above, by displaying the guidance information 20 separately in the display area A and the display area B of a predetermined display pattern, the position of various information is fixed and can be easily displayed to passers-by, and only a part of the information is displayed. It is possible to easily generate the guidance information 20 simply by changing.

  For example, in the plurality of double-sided displays 10, the guidance information 20 can be generated only by changing only the distance display portion of the display area B according to the installation position, and the distance display changes for a passerby moving according to the guidance information 20. Since it can be confirmed that the vehicle is approaching the destination without fail, the guidance efficiency can be improved.

  In addition, when the destination 40 to be guided is a store, it is possible to provide a lot of information about the store by changing and displaying the advertisement video of the store in the display area A at regular intervals.

  FIG. 4 is a process flow diagram showing an overview of the entire guidance system of the present invention.

  First, in step S1, the map information of the facility, the location information and priority of the store serving as the destination 40, the location information of the emergency exit, etc. are acquired as the facility information necessary for generating the guidance information 20, and the memory 8 To remember. Such facility information may be acquired by communicating with an external server, or may be acquired using information registered in a USB memory, a DVD-ROM, or the like.

  Next, in step 2, the position where the double-sided display 10 is installed and the orientations of the A side and the B side are acquired as installation information. Here, the position and direction are detected using a position sensor 5 and an orientation sensor 6 provided on the circuit board 4 of the double-sided display 10.

  Steps 1 and 2 above are executed as an initialization process when the guidance system is started up, and are repeatedly executed when there is no change in facility information such as stores and emergency exits or installation information of the double-sided display 10. do not have to.

  In step 3, the presence or absence of emergency information such as a fire or earthquake is confirmed. Emergency information communicates with the disaster detection system etc. in a facility by the communication part 7, and receives the emergency information emitted from a disaster detection system. If there is no emergency information, the process proceeds to step 4 to generate normal guidance information 20. If there is emergency information, the process immediately proceeds to step 5 to generate emergency guidance information 20. Details of the method for generating the guidance information 20 in steps 4 and 5 will be described later.

  In step 6, as shown in FIG. 3, guidance information 20 corresponding to the positional relationship with the destination 40 is displayed on the A and B surfaces of the double-sided display 10. Thereafter, the process returns to step 3 to confirm the emergency information again. If there is no emergency information, the guidance to the store is continued.

  As described above, in the guidance system using the double-sided display 10 of the present invention, when an emergency occurs, the destination 40 is immediately changed to an emergency exit and priority is given to evacuation guidance during normal times when guiding to a store or the like. Can be done.

  Next, generation of the guidance information 20 at the normal time in step 4 will be described in detail with reference to the processing flowchart shown in FIG.

  The normal destination 40 where emergency information has not been transmitted can be set automatically, for example, every predetermined time, or manually by specifying a predetermined store. Yes. In the processing flow of FIG. 5, after confirming the time in step 41, a store corresponding to the time is extracted and set from the registered stores in the memory 8 in step 42. Alternatively, step 41 can be omitted, and a predetermined store can be specified and set in step 42.

  In step 43, the route and distance to the set store are calculated. Here, the route and distance to the store can be calculated by comparing the location information of the store with the installation information of the double-sided display 10 against the map information of the facility.

  In step 44, since the direction of the store is known from the route, it is determined which display surface of the double-sided display 10 is the A surface (traveling direction) and the B surface (reverse direction).

  In step 45, guidance information 20 to be displayed on each of the A side and B side of the double-sided display is generated. Here, a display pattern suitable for the A side and the B side is acquired from the normal display pattern registered in the memory 8, the store image displayed in the display area A, the store direction and distance displayed in the display area B, and the like. Rewrite.

  As described above, the normal guidance information 20 can be generated.

  Next, generation of emergency guidance information 20 in step 5 will be described in detail with reference to the processing flowchart shown in FIG.

  If emergency information is received and it is determined that there is an emergency, in step 51, the route and distance from the installation position of the double-sided display 10 to each emergency exit in the facility is calculated. Here, the route and distance to each emergency exit can be calculated by collating the location information of each emergency exit and the installation information of the double-sided display 10 against the map information of the facility.

  In step 52, the emergency exit located at the shortest distance from the double-sided display 10 is set as the destination 40.

  In step 53, since the direction of the emergency exit is known from the route, it is determined which display surface of the double-sided display 10 is the A surface (traveling direction) and the B surface (reverse direction).

  In step 54, guidance information 20 to be displayed on each of the A side and B side of the double-sided display is generated. Here, a display pattern suitable for the A and B planes is acquired from the emergency display pattern registered in the memory 8, and the emergency message displayed in the display area A and the direction and distance of the emergency exit displayed in the display area B are displayed. Rewrite etc. Thereby, the passerby who confirmed guidance information 20 of double-sided display 10 can evacuate to the nearest emergency exit safely from the position.

  As described above, in the guidance system using the double-sided display 10 of the present invention, the A-side and B-side of the double-sided display 10 are automatically determined, and the guidance corresponding to the positional relationship with the destination 40 on each display surface. Information 20 can be easily generated. For this reason, it is not necessary to align the direction of the A side and the B side of the double-sided display 10 with respect to the destination 40 and to prepare display contents according to the A and B sides. Can be easily changed.

  Further, by communicating with and interlocking with the other double-sided display 10, it is possible to collectively change the guidance information 20 of the plurality of double-sided displays 10, and it is possible to eliminate setting errors of the guidance information 20.

  Further, by displaying the guidance information 20 corresponding to the positional relationship between the destination 40 on the A and B sides of the double-sided display 10, a passerby traveling on the traffic path 30 can see the A-side or B-side of the double-sided display 10. From any direction, since the outline (store, emergency exit) and position (direction, distance) of the destination 40 can be confirmed, the user can be guided to the destination 40 regardless of the traveling direction.

(Embodiment 2)
The guidance system according to the second embodiment enables guidance to a plurality of destinations 40 at the same time. What is different from the guidance system of the first embodiment is the method for generating the guidance information 20 in step 4 or step 5, and the others can be configured in the same manner as in the first embodiment, and therefore by adding the same reference numerals. A duplicate description is omitted.

  In the guidance system of the second embodiment, priority is set for a plurality of destinations 40 for each double-sided display 10 according to the positional relationship between the double-sided display 10 and the destination 40, and a high-priority purpose for each double-sided display 10. It is characterized by setting the ground 40.

  FIG. 7 is a processing flowchart when generating the normal guidance information 20 in the guidance system of the second embodiment.

  First, in step 401, the route and distance to each store are calculated for a plurality of stores that are candidates for the destination 40. The location information of a plurality of stores uses the information acquired in the memory 8 in step 1.

  In step 402, since the direction of each store is known from the route, it is determined which display surface of the double-sided display 10 is the A surface (traveling direction) and the B surface (reverse direction) for each store.

  FIG. 8 shows the distance of each store and the orientations of the A and B surfaces with respect to each store as an example of the processing results of the above steps 401 and 402. For example, the processing result of the double-sided display 10 shown in FIG. 8 indicates that the store A is 200 m away from the store 1, the A-side is facing the traveling direction, and the B-side is facing the direction opposite to the traveling direction. Yes.

  Next, in step 403, a priority for each store is set for each double-sided display 10. Here, a priority setting method using a priority setting sheet will be described.

  FIG. 9 is a priority setting sheet for setting the priority of each store. In this priority setting sheet, the priority is set based on a basic score set in advance for each store and a total score obtained by adding each prescribed score according to the positional relationship between the double-sided display 10 and the store.

  In FIG. 9, the basic points are points given to each store in advance, separately from the positional relationship with the double-sided display 10, and are set according to, for example, advertisement fees. The distance point is set so that the closer the distance between the double-sided display 10 and the store, the higher the score. The direction point is set so that, on the A and B surfaces of the double-sided display 10, the store direction is higher than the reverse direction when the store direction is the traveling direction.

  The total score shown in FIG. 9 is the sum of the above scores, and in this double-sided display 10, the store having a higher priority with respect to the A side becomes the store 1, and the store with a higher priority with respect to the B surface. It becomes store 2. Based on this result, the guidance information 20 with the store 1 as the destination 40 is displayed on the A side of the double-sided display 10, and the guidance information 20 with the store 2 as the destination 40 is displayed on the B surface. Thereby, it becomes possible to guide to a different store using one double-sided display 10.

  In addition, since the double-sided display 10 at another installation location can also be linked and guided to a plurality of stores, it is possible to eliminate the concentration of people at a specific store and causing congestion. Can be efficiently guided to other stores.

  As described above, in the guidance system using the double-sided display of the present invention, the priority is set for the plurality of destinations 40 according to the priority time zone, the orientation of the double-sided display 10, the distance to the destination 40, and the like. Since the destination 40 and its display contents can be changed, for example, the guidance to each store can be improved, and efficient guidance according to the request of each store can be performed.

  In the second embodiment, the method for generating the normal guidance information 20 has been described. However, the emergency guidance information 20 can also be generated in the same manner as described above. For example, evacuation guidance can be performed more safely by setting priority for each emergency exit in consideration of safety.

  As mentioned above, although Embodiment 1 and 2 of this invention were demonstrated concretely, this invention is not limited to them. Embodiments obtained by appropriately combining the technical means disclosed in the above-described two embodiments are also included in the technical scope of the present invention.
