Description

  The present invention relates to a route guidance system for pedestrians, for example, and more particularly to a route guidance system for guiding a route to a destination by optical display.

  Conventionally, a car navigation system for guiding a route to a destination of an automobile has been put into practical use. This system grasps the position of an automobile by GPS (Global Positioning System) and guides a route by map information and voice on a display.

  By the way, development of a route guidance system (navigation system) for pedestrians other than automobiles is being promoted. This system provides a service that uses a mobile phone equipped with GPS to determine the location of the user carrying the mobile phone using the GPS, and provides route guidance to the destination by means of map display and voice. .

  However, since the system uses GPS, it can be used outdoors. However, in particular indoors, GPS satellites cannot capture the position, and thus cannot perform route guidance. In particular, when targeting pedestrians, the method of displaying a map on a mobile phone screen and guiding the route causes the user to walk while looking at the screen, which also causes a safety problem.

Thus, a route guidance system has been proposed that uses a portable terminal not equipped with GPS to provide guidance information to the portable terminal (for example, see Patent Document 1). In addition, a system has been proposed in which guidance information for route guidance is displayed not only on a user's portable terminal but also on a display device installed in an environment around the route (see, for example, Patent Document 2).
JP 2002-162246 A JP 2002-54945 A

  If the system is proposed by the above-mentioned prior art document, indoor route guidance is possible. Further, the route can be confirmed by displaying on the display device without looking at the screen of the portable terminal carried by the pedestrian.

  However, in particular, when guiding routes to a plurality of destinations to a plurality of users, merely displaying on the display device is not sufficient for providing easy-to-understand guidance to the users.

  Accordingly, an object of the present invention is to provide a route guidance system capable of realizing route guidance that is easy for the user to understand by optical display.

  An aspect of the present invention is a route guidance system that communicates with a terminal device carried by a user who is a pedestrian, for example, and optically displays a route to a destination designated by the user.

A route guidance system according to an aspect of the present invention provides ID information for identifying a terminal device with a terminal device moving in a guidance target area, and a purpose indicating a destination specified in the guidance target area. Means for communicating information including location information by wireless communication, and position information communication for transmitting current position information of the terminal device by wireless communication when the terminal device has moved to a position set in the guidance target area A route determining unit that calculates, for each ID information, route information corresponding to a guide route to a destination based on the current location information and the destination information transmitted from the location information communication unit, and the route Light for controlling the light indicator arranged in the guidance target area according to the route information calculated by the determining means and emitting and displaying the guidance route in a designated display color示制a control means, a configuration in which a light display control means for transmitting information indicating the status of the guidance route determined by a visible light communication by said route determination means.

  According to the present invention, since the guidance route to the destination can be displayed by changing the display color for each user, it is possible to realize easy-to-understand route guidance.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a conceptual diagram for explaining a configuration of a route guidance system according to the present embodiment.

  The present embodiment is a system that, for example, assumes an indoor traffic museum as the guidance target area 1, and guides a user who is, for example, a pedestrian (visitor) to the exhibition rooms 3 to 6, which are destinations. .

  The user rents the portable terminal device 12 at the reception 2 of the traffic museum, for example. The terminal device 12 is a portable information terminal such as a PDA, for example, and is transmitted from a radio frequency identification (RFID) tag 10 described later and a function of performing wireless communication with the server 11 that is the main control device of the system. A reader function for receiving (reading) information (ID information and position information). In addition, the terminal device 12 includes a display screen (see FIG. 3) that displays information transmitted from the server 11 and a sound output device such as a speaker that reproduces sound information transmitted from the server 11.

  In the guidance target area 1 indoors of the traffic museum, an RFID tag 10 is installed under the floor or wall near the entrance of the exhibition rooms 3 to 6 corresponding to the destination. In addition, RFID tags 10 are installed under a plurality of floors or walls necessary for setting a guide route to each destination. Each RFID tag 10 wirelessly transmits position information for identifying each installation position.

  Here, the position information transmitted from each RFID tag 10 is code information indicating the position or ID information (identification code) for identifying each RFID tag 1. The server 11 receives the position information via the terminal device 12 and recognizes the position of the RFID tag 10 existing in the vicinity of the terminal device 12.

  Further, in the guidance target area 1, a plurality of light indicators 20 made of, for example, LEDs (light emitting devices) which are color light emitting elements are arranged on, for example, a floor surface or a wall surface. The optical display 20 is usually arranged based on a route that can be guided in advance. Moreover, the light indicator 20 may be arrange | positioned in the designated range in the guidance object area 1, for example in a matrix structure. Furthermore, the light indicator 20 may be disposed on the entire surface of the guidance target area 1.

  The server 11 is configured to turn on or off each of the arranged optical indicators 20 and control lighting with a designated display color. In addition, as shown in FIG. 1, each light indicator 20 is visually easy for the user by a band or arrow shape of light that flows (moves) in the traveling direction so that the guide direction can be visually confirmed. It has a light emitting surface to the extent that can be confirmed.

(Route guidance procedure in the first embodiment)
Hereinafter, the route guidance procedure in this embodiment will be described with reference to the flowchart of FIG. 2 together with FIG.

  First, when the user borrows the terminal device 12 at the reception 2, the user operates the terminal device 12 to set a destination (step S1). Here, as shown in FIG. 3A, the terminal device 12 has a function of displaying a setting screen for selecting and setting the exhibition rooms 3 to 6 which are destinations. On the setting screen, the user sets, for example, an automobile exhibition room 3 as a destination.

  The terminal device 12 transmits, to the server 11, destination information indicating the set destination (here, the car exhibition room 3) by wireless communication. Here, the server 11 and the terminal device 12 perform wireless communication based on the Bluetooth (registered trademark) standard, which is a short-range wireless standard, for example.

  As the user moves, the terminal device 12 receives position information from the RFID tag 10 installed in the reception 2 and outputs, for example, guidance information stored in advance as voice (steps S2 and S3). Here, as shown in FIG. 3B, the terminal device 12 may display guide information prepared in advance on the display screen.

  When the server 11 receives the position information, the destination information, and the ID information transmitted from the terminal device 12, the server 11 stores them in the internal storage device (step S4). Based on the acquired position information, destination information and ID information, the server 11 determines a guide route to the destination (vehicle exhibition room 3), and calculates route information indicating the guide route (step S5). .

  Here, the guide route is related to the arrangement of the light indicators 20 described above. Further, the server 11 may determine the congestion status at each point based on the position information transmitted from the plurality of terminal devices 12 and execute a process of excluding the crowded route from the guidance route.

  Next, in accordance with the calculated route information, the server 11 sequentially turns on each light indicator 20 corresponding to the determined direction of the guide route at regular intervals, and displays each light so as to light-display the route to the destination. The device 20 is controlled (step S6). Here, when controlling each light indicator 20, the server 11 performs control so that light is displayed in a different display color for each ID information.

  By the route guidance processing as described above, the user moves according to the route optically displayed by each light indicator 20 as shown in FIG. When the terminal device 12 moves and receives position information at the point where the RFID tag 10 is installed, the terminal device 12 transmits it to the server 11 together with the ID information and the destination information. The server 11 determines the next route from the current position to the destination, and controls each light indicator 20 so as to light-display the route (steps S4 to S6).

  Then, when the terminal device 12 receives the position information at the point where the RFID tag 10 installed at the entrance of the exhibition room 3 of the automobile which is the destination is installed and transmits it to the server 11, the route guidance is completed. In this case, as shown in FIG. 3C, the terminal device 12 may display guidance information indicating arrival at a destination prepared in advance on the display screen.

  In the system according to the present embodiment, the user simply operates the terminal device 12, and the route to the vehicle exhibition room 3, which is the destination, emits light from each of the optical indicators 20 arranged on the floor or wall surface. It can be easily grasped simply by confirming the display. Here, even if a plurality of users are simultaneously guided in the same direction, the display color is different for each ID information (for each user), so that each user can easily distinguish his / her own guidance route.

  In addition, the display color for every user is determined by the display color when light-displaying, for example when starting guidance from the reception desk 2, for example. Alternatively, the server 11 may transmit information indicating a display color to the terminal device 12 and display the information on the display screen of the terminal device 12.

(Processing procedure of the server 11)
Hereinafter, the processing procedure of the server 11 will be described with reference to FIGS. 12 to 14.

  First, the server 11 establishes wireless communication with the terminal device 12 and enters a reception waiting state in which information from the terminal device 12 is received (step S50). As described above, when the server 11 receives the position information, the destination information, and the ID information transmitted from the terminal device 12, the server 11 stores them in the internal storage device (steps S51 and S52).

  Here, the server 11 determines whether or not the acquired ID information of the terminal device 12 has already been registered, and identifies whether the user has started guidance for the first time or has already started guidance (step S53). ). When the received ID information is unregistered, the server 11 sets a display color for displaying the light emission of each light indicator 20 (step S54). Specifically, as shown in FIG. 12, the server 11 creates display color table information 200 and manages display colors set for each ID information.

  Next, as described above, the server 11 determines a guide route to the destination (the vehicle exhibition room 3) based on the position information, the destination information, and the ID information, and creates route information (step S55). ). Specifically, as shown in FIG. 13, the server 11 creates table information 210 in which destination information, current position information, and display numbers of the respective light indicators 20 to be lit and displayed are set.

  And the server 11 performs the light emission display control of each light indicator 20 according to the said route information (table information 210) (step S56). At this time, the server 11 refers to the display color table information 200 and sets a display color for each ID information (user).

  The server 11 may use a method of setting the display color for each destination information instead of the ID information when creating the display color table information 200. In this case, if the user is guided in advance about the display colors for each of the exhibition rooms 3 to 6, the user can easily reach the destination by moving the guide route indicated by the light emission display color of each light indicator 20. be able to.

  The transmission unit 134 transmits the information stored in the transmission information storage unit 133 to the server 11a by wireless communication.

Next, the route guidance procedure of this embodiment is demonstrated with reference to the flowchart of FIG.19 and FIG.20.
First, as shown in FIG. 20, the user inputs destination information via the input unit 131 (step S72). Next, the terminal device 12 a reads terminal ID information from the terminal ID storage unit 132.

  Next, the terminal device 12a acquires position information transmitted by the RFID tag 10 (step S73). In the terminal device 12a, the destination information, terminal ID information, and position information are stored in the transmission information storage unit 133 (step S74).

  The terminal device 12a compares the destination information stored in the transmission information storage unit 133 with the position information (step S75). If the current position indicated by the position information acquired by the terminal device 12a is not the destination indicated by the destination information, for example, the voice output unit 128 outputs voice information stored in advance as a voice (NO in step S75, S76). ). The guide information may be displayed on the display screen of the terminal device 12a by the information display unit 130.

  Next, the terminal device 12a performs transmission processing for transmitting the destination information, terminal ID information, and position information stored in the transmission information storage unit 133 to the server 11a by wireless communication (step S77). On the other hand, when the current position indicated by the position information is the destination indicated by the destination information, the terminal device 12a outputs an arrival message (YES in step S75, S78).

  Next, processing performed by the server 11a will be described with reference to FIG.

  The route calculation processing unit 114 calculates the destination from the current position based on the destination information, the terminal ID information and the position information transmitted from the terminal device 12a, and each information stored in the database (DB) 113 of the server 11a. Route information indicating the guide route up to is created (step S63). The route calculation processing unit 114 refers to a terminal ID database, a location database, and a map database included in the database (DB) 113 to determine a guide route for each terminal ID information.

  Next, the light emission control information creating unit 122 creates light emission control information for controlling the light indicator 20a based on the created route information (step S64).

  The input unit 116 inputs information on the status of the guidance route indicated by the route information by the operation of the operator (step S65). The additional information creation unit 117 creates additional information based on the input information and each information stored in the database 113 (step S66).

  The transmission processing unit 118 performs a transmission process for transmitting the light emission control information and the additional information created in steps S64 and S66 to the optical display 20a by the wireless communication 15 (step S67).

  On the other hand, as shown in FIG. 19, the light display control unit 204 controls the light indicator 20a based on the light emission control information transmitted by the server 11a (step S68). Next, the modulation unit 205 modulates the fixed information and the additional information into a signal that allows visible light communication with the terminal device 12a (step S70). Here, the fixed information is information read from the fixed information storage unit 202 (step S69). The light emitter 206 emits light according to control by the light display control unit 204 (step S71).

  In the portable terminal 12a, as shown in FIG. 20, the fixed information and the additional information transmitted from the optical display 20a by visible light communication are output by the audio output unit 128 (step S79). Here, the voice conversion processing unit 127 converts the fixed information and the additional information into a data format that can be output as voice. The fixed information and the additional information may be displayed on the display screen by the information display unit 130.

  After the above operation, the process returns to step S75 and the above processing is repeated. In step S75, when the current position indicated by the position information is the destination indicated by the destination information, the terminal device 12a outputs an arrival message (step S78). This is because it is determined that the user has already arrived at the destination.

  Here, the arrival message output by the terminal device 12a is, for example, an audio output by the audio output unit 128. The arrival message may be displayed on the display screen by the information display unit 130. Moreover, the structure output by both the audio | voice output part 128 and the information display part 130 may be sufficient.

This is a system that provides route guidance to exhibition rooms 3-6.

  In the present embodiment, the terminal device 12b includes a light emitter, and the terminal device 12b and the optical display device 20b are configured to be capable of visible light communication in both directions. In the present embodiment, the server 11 b and the optical display 20 b are configured to be able to communicate bidirectionally by the wireless communication 15. In FIG. 16, the same components as those described in the first embodiment and the sixth embodiment described above are denoted by the same reference numerals and description thereof is omitted.

Next, the configuration of the route guidance system in this embodiment will be described with reference to FIG.
FIG. 18 is a block diagram showing the configuration of the route guidance system of this embodiment. The route guidance system of this embodiment is a modification of the sixth embodiment, and includes a server 11b, a terminal device 12b, and an optical display 20b. In FIG. 18, the same components as those described in the sixth embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The server 11b includes a transmission / reception unit 120 and a reception information storage unit 121 instead of the reception unit 111 and the transmission unit 119 of the server 11a illustrated in FIG.

  The transmission / reception unit 120 has a function of transmitting light emission control information and additional information to the optical display 20b through the wireless communication 15, and includes destination information, terminal ID information, and the like transmitted from the optical display 20b through the wireless communication 15. It has a function of receiving position information. The reception information storage unit 121 is used as a storage unit that stores destination information, terminal ID information, and position information received by the transmission / reception unit 120.

  The optical display 20b includes a transmission / reception unit 210 instead of the reception unit 201 of the optical display 20a illustrated in FIG. 17, and further includes a visible light reception unit 207, a reception information storage unit 208, and a transmission information creation unit 209.

  The visible light receiving unit 207 includes a light receiving unit 207a and a demodulating unit 207b. The light receiving unit 207a has a function of receiving destination information and terminal ID information transmitted from the terminal device 12b by visible light communication and generating reception information. The demodulating unit 207 b has a function of demodulating the destination information and terminal ID information received by the light receiving unit 207 a into a readable data format and sending it to the received information storage unit 208. The reception information storage unit 208 is used as a storage unit for storing destination information and terminal ID information data received and demodulated by the visible light reception unit 207.

  The transmission information creation unit 209 performs processing for transmitting the destination information and the terminal ID information stored in the reception information storage unit 208 to the server 11b by wireless communication. Here, processing for transmitting the positional information stored in the fixed information storage unit 202 of the optical display 20b to the server 11b is also performed.

  The transmission / reception unit 210 has a function of transmitting destination information, terminal ID information, and position information to the server 11b, and a function of receiving light emission control information and additional information transmitted from the server 11b.

  The terminal device 12b includes a modulation unit 135 and a light emitter 136 instead of the RFID reception unit 125 and the RFID reception information storage unit 126 of the terminal device 12a illustrated in FIG.

  The modulation unit 135 modulates the destination information and terminal ID information stored in the transmission information storage unit 133 into a data format that allows visible light communication. The light emitter 136 is, for example, an LED which is a color light emitting element used for visible light communication.

Next, the route guidance procedure of this embodiment is demonstrated with reference to the flowchart of FIG.21 and FIG.22.
First, as shown in FIG. 22, the user inputs destination information via the input unit 131 (step S100). Next, the terminal device 12b reads the terminal ID information from the terminal ID storage unit 132.

  Next, as shown in FIG. 21, the optical display 20b reads the position information stored in the fixed information storage unit 202 (step S88). Next, the modulation unit 205 performs modulation processing to transmit the read position information by visible light communication (step S89). By this modulation processing, the position information is modulated into a data format that allows visible light communication. The modulated position information is transmitted by visible light communication (step S90).

  Next, returning to FIG. 22, the processing of the terminal device 12b will be described. In the terminal device 12b, the destination information, the terminal ID, and the position information are stored in the transmission information storage unit 133 (Step S101). Next, the terminal device 12b compares the destination information stored in the transmission information storage unit 133 with the position information (step S102). If the position information acquired by the terminal device 12b is not the destination indicated by the destination information, for example, the voice output unit 128 outputs the stored guidance information by voice (NO in step S102, S103). The guide information may be displayed on the display screen of the terminal device 12b by the information display unit 130.

  Next, the terminal device 12b modulates and transmits the destination information and terminal ID information stored in the transmission information storage unit 133 so as to be transmitted to the optical display 20b by visible light communication (steps S104 and S105). On the other hand, when the position information acquired by the terminal device 12b is the destination indicated by the destination information, the terminal device 12b outputs an arrival message (YES in S102, S106).

  Next, with reference to FIG. 21, the process performed by the optical display 20b will be described. The optical display 20b determines whether the destination information and the terminal ID information transmitted by the terminal device 12b have been received (step S91). If the optical display 20b has not received the information, it waits until it is received (NO in step S91). When the optical display 20b receives the information, the optical display 20b processes the received data (YES in step S91, S92). Here, the demodulator 207b demodulates the destination information and terminal ID information received by the light receiver 207a into a readable data format.

  Next, the transmission information creation unit 209 creates data to be transmitted to the server 11b from the demodulated destination information and terminal ID information (step S93). At this time, the transmission information creation unit 209 creates data to be transmitted to the server 11b from the position information stored in the fixed information storage unit 202. Then, this data is subjected to transmission processing, and then transmitted to the server 11b by the transmission / reception unit 210 (step S94).

  Next, the route calculation processing unit 114 of the server 11b presents the current information based on the destination information, the terminal ID information and the position information transmitted from the optical display 20b, and each information stored in the database (DB) 113. Route information indicating a guide route from the position to the destination is created (step S83). Further, the route calculation processing unit 114 refers to the terminal ID database, the position database, and the map database included in the database (DB) 113 to determine a guide route for each terminal ID information.

  Next, the light emission control information creating unit 122 creates light emission control information for controlling the light indicator 20b based on the created route information (step S84).

  The input unit 116 inputs information about the status of the guidance route indicated by the route information by the operation of the operator (step S85). The additional information creation unit 117 creates additional information based on the input information and each information stored in the database 113 (step S86).

  The transmission processing unit 118 performs a transmission process for transmitting the light emission control information and the additional information created in step S84 and step S86 to the optical display 20b through the wireless communication 15 (step S87).

  Next, the light indicator 20b determines whether or not the light emission control information and the additional information transmitted by the server 11b have been received (step S95). If the optical display 20b has not received the information, it waits until it is received (NO in step S95). When the light display 20b receives the information, the light display control unit 204 controls the light display 20b based on the light emission control information transmitted by the server 11b (YES in step S95, S96).

  Next, the modulation unit 205 modulates the fixed information and the additional information so as to be transmitted to the terminal device 12 by visible light communication (step S98). Here, the fixed information is information read from the fixed information storage unit 202 (step S97). The light emitter of the optical display 20b emits light according to control by the optical display control unit 204 of the optical display 20b (step S99).

  Next, as shown in FIG. 22, in the terminal device 12b, the fixed information and the additional information transmitted from the optical display 20b by visible light communication are output by the audio output unit 128 (step S107). Here, the voice conversion processing unit 127 converts the fixed information and the additional information into a data format that can be output as voice. The fixed information and the additional information may be displayed on the display screen by the information display unit 130.

  After the above operation, the process returns to step S102 and the above-described processing is repeated. In step S102, when the current position indicated by the position information is the destination indicated by the destination information, the terminal device 12b outputs an arrival message (step S106). This is because it is determined that the user has already arrived at the destination.

  Here, the arrival message output by the terminal device 12b is, for example, an audio output by the audio output unit 128. The arrival message may be displayed on the display screen by the information display unit 130. Moreover, the structure output by both the audio | voice output part 128 and the information display part 130 may be sufficient.

  As described above, with the system according to the present embodiment, the user can easily reach the destination by moving the guidance route indicated by the light emission display of each light indicator 20b. Further, since the terminal device 12b reads position information from the optical display 20b and sends information to the server 11b via the optical display 20b, the terminal device 12b also uses a light flow that guides the user without using the RFID tag 10. Information can be transmitted by visible light communication. Therefore, it becomes possible to provide more information.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment.
