Embodiment 1 FIG.
FIG. 1 is a block diagram showing a user guidance system according to Embodiment 1 of the present invention. In the figure, the user guidance system has a guidance information distribution device 10 and an information provision device 20. The guidance information distribution device 10 is installed in a building that is a management area. The information providing apparatus 20 according to the first embodiment is a robot that automatically moves to a destination in a building, that is, a moving body.

The guidance information distribution device 10 includes a map information storage unit 11, a distribution control unit 12, and a distribution device communication unit 13. The map information storage unit 11 stores map information in the building. The distribution control unit 12 transmits guide information that is at least part of the map information to the information providing device 20 via the distribution device communication unit 13. The distribution control unit 12 has a timer (not shown).

Further, when transmitting the guide information to the information providing device 20, the distribution control unit 12 adds restriction information, which is information regarding a condition that makes the use of the guide information unusable, to the guide information, and sends the guide information and the limit information to the information. To the providing device 20. The restriction information defines the effective range of permission to use the guidance information.

The restriction information includes at least one of the following a to e.
a: Information that disables the use of guide information when the information providing apparatus 20 receives a deletion command.
b: Information that disables the use of guidance information when the information providing apparatus 20 exits the designated area.
c: Information that disables the use of the guidance information by connecting or disconnecting the designated communication to the information providing apparatus 20.
d: Information on the time at which guide information cannot be used.
e: Time information from when the guidance information is transmitted until the guidance information becomes unusable.

The information providing device 20 receives the guide information from the guide information distribution device 10 and provides it to the user. Even when the information providing apparatus 20 moves unattended, the guide information is indirectly provided to the user who uses the information providing apparatus 20 by transmitting the guide information to the information providing apparatus 20. .

The information providing device 20 includes an information providing control unit 21, a providing device communication unit 22, a guide information storage unit 23, a reproduction unit 24, a drive unit 25, and a drive control unit 26.

The information provision control unit 21 receives guidance information and restriction information from the guidance information distribution device 10 via the provision device communication unit 22. The guide information storage unit 23 stores guide information and restriction information.

The information provision control unit 21 deletes the guidance information and the restriction information from the guidance information storage unit 23 when a condition that prohibits the use of the guidance information in the restriction information is satisfied. Further, the information provision control unit 21 has a timer (not shown).

Also, when the guide information is deleted from the guide information storage unit 23, the information provision control unit 21 stores the deletion history information in the guide information storage unit 23. The deletion history information includes at least one of information regarding the deletion time, information regarding the reason for deletion, and information regarding the position of the information providing apparatus 20 at the time of deletion.

Also, the information provision control unit 21 transmits the deletion history information to the guidance information distribution device 10. The guidance information distribution device 10 stores the received deletion history information.

The distribution control unit 12 monitors whether or not the number of times the guidance information is transmitted to the same information providing apparatus 20 matches the number of times the deletion history information is received from the information providing apparatus 20. Then, when the number of transmissions and the number of receptions do not match, the distribution control unit 12 prohibits subsequent transmission of guidance information to the information providing apparatus 20.

In addition, the information provision control unit 21 requests the guide information distribution apparatus 10 for a file format of the received guide information. The distribution control unit 12 selects the guide information in the file format requested from the information provision control unit 21 and transmits it to the information provision apparatus 20.

FIG. 2 is a block diagram showing an example of the device configuration of the guidance information distribution device 10 of FIG. The guidance information distribution device 10 includes a communication device 31, a processor 32, a memory 33, and a display 34. The function of the guidance information distribution apparatus 10 is realized by a computer shown in FIG. The memory 33 stores map information and a program for executing the function of the guidance information distribution device 10. The processor 32 executes arithmetic processing according to a program.

The apparatus configuration of the information providing apparatus 20 is the same as that shown in FIG. That is, the function of the information providing apparatus 20 is realized by a computer different from the guidance information distribution apparatus 10.

FIG. 3 is a flowchart showing the operation of the guidance information distribution apparatus 10 of FIG. The guidance information distribution apparatus 10 repeatedly executes the process of FIG. 3 at a set cycle. In the process of FIG. 3, the guidance information distribution apparatus 10 first checks whether or not deletion history information has been received (step S11). When the deletion history information is received, the number of times of deletion history information reception is added once (step S12), and the processing for that time is terminated.

If the deletion history information has not been received, it is confirmed whether a request for guidance information has been received from the information providing device 20 (step S13). If the guide information request is not received, the process is terminated. When a request for guidance information is received, it is determined whether or not the guidance information can be transmitted to the requested information providing apparatus 20 from the comparison result between the number of times the guidance information is transmitted and the number of times the deletion history information is received (step S14). ).

When permitting transmission of guide information to the information providing apparatus 20, guide information and restriction information are created (step S15), and the created guide information and restriction information are sent to the information providing apparatus 20 (step S16). If transmission of guidance information is not permitted, the process is terminated without doing anything. In this case, information indicating that transmission of the guidance information is rejected may be transmitted to the information providing apparatus 20.

The guidance information distribution device 10 transmits the guidance information and the restriction information to the information providing device 20, and then adds the number of times the guidance information is transmitted (step S17), and ends the processing of that time.

FIG. 4 is a flowchart showing the operation of the information providing apparatus 20 of FIG. When the information providing device 20 enters the building, the information providing device 20 requests the guide information distribution device 10 to transmit the guide information, and repeatedly executes the processing of FIG. 4 at a set cycle.

4, the information providing apparatus 20 confirms whether or not the guide information has been received (step S21). If not received, it is confirmed whether or not the guide information has been received (step S22). If it has not been received, the process is immediately terminated. When the guide information is received, the guide information and the restriction information are stored (step S23), and the process for that time is terminated. When the guide information is received, the restriction information is always added to the guide information.

If the guide information has been received in step S21, it is determined whether or not a condition for disabling use of the guide information in the restriction information is satisfied (step S24). If the condition is not satisfied, the process is immediately terminated.

If the condition that prohibits the use of the guidance information in the restriction information is satisfied, the guidance information and the restriction information are deleted (step S25). Then, the deletion history information is transmitted to the guidance information distribution apparatus 10 (step S26), and the operation of FIG.

In such a guide information distribution device 10, since restriction information is added to the guide information, inappropriate use of the map information in the management area can be suppressed.

Also, the burden on the information providing apparatus 20 can be reduced as compared with the case where the local secure navigation module shown in Patent Document 1 is downloaded.

In addition, the restriction information includes at least one of the above a to e. For this reason, improper use of the map information in the management area can be more reliably suppressed.

For example, if the restriction information d or e is used, the use of the guidance information can be disabled even when the position of the information providing device 20 cannot be recognized.

In addition, the information provision control unit 21 deletes the guide information from the guide information storage unit 23 when a condition that prohibits the use of the guide information in the restriction information is satisfied. For this reason, improper use of the map information in the management area can be more reliably suppressed. In addition, it is possible to use a function for deleting guide information while maintaining the operational quality of services under various environments.

Also, there is a case of moving from the security area to another security area across the open area that is a space outside the security area. In this case, it is not necessary to download the local secure navigation module every time the security area is entered, which is highly convenient.

It should be noted that “by designated communication connection...” In the restriction information c may be either at the time of designated communication connection or after a set time has elapsed since the designated communication connection. Similarly, “by disconnection of designated communication” may be either when the designated communication is disconnected or after a set time has elapsed since the designated communication was disconnected.

Suppose, for example, that the map information in the management area cannot be used unless communication with the designated server is connected. For Wi-Fi, LTE, etc., unintended communication disconnection and connection may occur depending on the communication environment. Considering this point, it is preferable to disable the use of the guidance information after a set time has elapsed since the disconnection of the designated communication.

For example, a case will be described in which the Wi-Fi communication area of SSID001 moves to the Wi-Fi communication area of SSID002. In this case, in order to delete map data valid in the area 001 more reliably, it is desirable to set a condition of disconnection of communication with SSID001 or connection of communication with SSID002.

Also, by deleting after waiting for a certain time from connection or disconnection of communication, inconvenient events at the boundary between communication areas can be suppressed. An inconvenient event is, for example, an event in which map data of 001 is deleted while it is still in the area of 001 during movement between communication areas.

Further, since the information provision control unit 21 stores the deletion history information in the guidance information storage unit 23, it is possible to confirm whether or not the guidance information is properly deleted by confirming the recording in the guidance information storage unit 23. it can.

Further, the information provision control unit 21 transmits the deletion history information to the guidance information distribution device 10, and the guidance information distribution device 10 stores the received deletion history information. For this reason, it is possible to monitor on the guide information distribution apparatus 10 side whether or not the guide information is properly deleted.

Further, the distribution control unit 12 monitors whether or not the number of times the guidance information is transmitted to the information providing apparatus 20 and the number of times the deletion history information is received from the information providing apparatus 20 match. Thereby, the reliability of the information provision apparatus 20 can be determined more appropriately.

The deletion history information includes at least one of information regarding the time of deletion, information regarding the reason for deletion, and information regarding the position of the information providing apparatus 20 at the time of deletion. For this reason, it can be confirmed more reliably whether guidance information was deleted appropriately.

Note that the deletion history information may be transmitted to the guide information distribution device 10 without being stored in the guide information storage unit 23.

Further, even after the restriction information condition is satisfied, the information providing apparatus 20 may permit the information providing apparatus 20 to hold the information as long as the information is simplified. The simplified information is, for example, map information simplified as a polygon box.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. The configuration of the user guidance system of the second embodiment is the same as that of the first embodiment. Therefore, the second embodiment will also be described with reference to FIG.

The distribution control unit 12 according to the second embodiment encrypts the guide information when transmitting the guide information to the information providing apparatus 20. The information providing apparatus 20 according to the second embodiment decodes the guide information and provides it to the user. The encryption key is provided separately to the user.

Also, the information provision control unit 21 receives the guidance information via the provision device communication unit 22. In addition, the information provision control unit 21 decrypts the guide information using the encryption key. The information provision control unit 21 adds signature information indicating at least one of the guidance information distribution device 10 and the information provision device 20 to the guidance information when decoding the guidance information. Other configurations and operations are the same as those in the first embodiment.

In such a user guidance system and information providing apparatus 20, since signature information is added to the guidance information when the guidance information is decrypted, even if the guidance information is not properly deleted and leaked, The original can be traced. For this reason, improper use of the map information in the management area can be suppressed.

In the user guidance system and the information providing apparatus 20 according to the second embodiment, the guidance information does not necessarily have to be automatically deleted based on the restriction information. When the restriction information is not added to the guide information, the guide information may be deleted by the user. Even in this case, by letting the user know that the signature information is added to the guide information, the outflow of the guide information can be suppressed.

In the first and second embodiments, the distribution control unit 12 may select only a part of the map information as guide information according to the destination information received from the information providing device 20. However, in some cases, the distribution control unit 12 may use the entire map information as guidance information.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described. The configuration of the user guidance system of the third embodiment is the same as that of the first embodiment. Therefore, Embodiment 3 will also be described based on FIG.

The map information of the third embodiment includes a plurality of pieces of divided map information respectively corresponding to a plurality of security areas in the management area. When the guide information includes one or more pieces of divided map information, the distribution control unit 12 according to the third embodiment transmits the guide information encrypted with a different encryption key for each piece of divided map information to the information providing apparatus.

The information provision control part 21 of Embodiment 3 designates and decodes division | segmentation map information separately. The encryption key is provided separately to the user. The information provision control unit 21 adds signature information similar to that of the second embodiment to the guide information when decoding the divided map information. Other configurations and operations are the same as those in the first embodiment.

In such a user guidance system and guidance information distribution apparatus 10, when at least one divided map information is included in the guidance information, the divided map information is encrypted with a different encryption key. For this reason, even if one divided map information flows out, it is suppressed that other divided map information flows out. Thereby, improper use of the map information in the management area can be suppressed.

In addition, since the encryption key can be managed by the right holder for each security area, even if one encryption key is leaked, the divided map information of the security area other than the security area corresponding to the leaked encryption key Never become public.

In addition, since signature information is added to the guide information when the divided map information is decrypted, the outflow source can be traced even if the guide information is leaked without being properly deleted. For this reason, improper use of the map information in the management area can be more reliably suppressed.

In the user guidance system and guidance information distribution apparatus 10 according to the third embodiment, the guidance information does not necessarily have to be automatically deleted based on the restriction information. When the restriction information is not added to the guide information, the guide information may be deleted by the user. Even in this case, improper use of the map information in the management area can be suppressed by performing encryption with different encryption keys for each piece of divided map information.

In the user guidance system and the information providing apparatus 20 according to the third embodiment, it is not always necessary to add signature information to the guidance information.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described. The configuration of the user guidance system of the fourth embodiment is the same as that of the first embodiment. Therefore, the fourth embodiment will also be described based on FIG.

The information providing apparatus 20 according to the fourth embodiment transmits the destination information to the guidance information distribution apparatus 10. The distribution control unit 12 according to the fourth embodiment creates guidance information for guiding the information providing apparatus 20 to the destination according to the destination information received from the information providing apparatus 20. The guidance information includes a plurality of pieces of image information corresponding to the position of the information providing apparatus 20, a plurality of traveling direction information corresponding to the position of the information providing apparatus 20, and a plurality of traveling distance information corresponding to the position of the information providing apparatus 20. And are included.

The guidance information distribution device 10 can detect the current position of the information providing device 20 by at least one of a plurality of sensors installed in the management area and a signal from the information providing device 20.

When the management area is in a building, the map information includes a plurality of feature information. Each feature information is an image of an object in the building for the user to determine which location in the building. The image information of the guidance information includes feature information.

Characterization information includes, for example, floor patterns, wall patterns, stairs, doors, indoor installations, and elevator halls. Examples of the indoor installation include a counter and a lighting fixture.

The traveling direction information and the traveling distance information are message information such as “turn right after 100 m”, for example. Other configurations and operations are the same as those in the first embodiment.

In such a guidance information distribution device 10 and a user guidance system, guidance information including traveling direction information and traveling distance information corresponding to the position of the information providing device 20 is created according to the destination information. For this reason, map data does not remain in the information providing device 20, and inappropriate use of map information in the management area can be suppressed.

Also, by adding image information to the guide information, the guide information can be made easier to understand.

Also, by adding feature information to the image information, the guide information can be made easier to understand.

Note that the guidance information may be deleted after use or may not be deleted as in the first embodiment.

Further, if the information providing device 20 can grasp its own position in the management area, the guide information distributing device 10 may collectively transmit all the guide information to the information providing device 20 at the departure place.

Further, the distribution control unit 12 may divide the route from the departure place to the destination into a plurality of sections and divide the guide information into divided guide information corresponding to each section. In this case, the distribution control unit 12 sequentially transmits the division guide information corresponding to the position of the information providing device 20. Thereby, the outflow of the information in a management area can be suppressed more reliably.

In addition, the guidance information may not include image information.

Embodiment 5 FIG.
Next, FIG. 5 is a block diagram showing a user guidance system according to Embodiment 5 of the present invention. The guidance information distribution device 40 according to the fifth embodiment includes a distribution device main body 41, a guidance information transmitter 42, an identification information receiver 43, and a request signal transmitter 44.

The distribution apparatus main body 41 has the same configuration as the guidance information distribution apparatus 10 of the first embodiment. The guide information transmitter 42 is installed at the intersection of a plurality of indoor passages in the management area. The guide information transmitter 42 is installed on the ceiling of the intersection. The guide information transmitter 42 can individually transmit infrared signals to a plurality of indoor passages.

The distribution apparatus main body 41 transmits guide information to the information providing apparatus 20 via the guide information transmitter 42. The guidance information includes travel direction information and travel distance information at the intersection. The traveling direction information is information indicating which indoor passage to proceed from the intersection. The travel distance information is information indicating how far the vehicle travels from the intersection.

The configuration of the information providing apparatus 20 is the same as that of the first embodiment, and details are omitted in FIG.

The identification information receiver 43 is installed on the ceiling of the intersection of the indoor passage. The information providing apparatus 20 can transmit identification information to the identification information receiver 43. The identification information is an infrared signal. The identification information receiver 43 individually receives the identification information from the information providing apparatus 20 for each indoor passage and sends it to the distribution apparatus main body 41.

The distribution control unit 12 transmits guide information corresponding to the identification information to the information providing device 20 via the distribution device communication unit 13 and the guide information transmitter 42.

The request signal transmitter 44 is installed near the identification information receiver 43 in the vicinity of the intersection of the indoor passage. The request signal transmitter 44 periodically transmits a request signal for requesting the information providing apparatus 20 to transmit identification information to the corresponding indoor passage. When receiving the request signal, the information providing apparatus 20 transmits the identification information to the identification information receiver 43.

The distribution apparatus main body 41 monitors the reception state of the identification information. Thereby, the distribution apparatus main body 41 detects that the information providing apparatus 20 has moved to a position outside the receivable range of the identification information receiver 43 after starting transmission of the identification information.

For example, when the information providing apparatus 20 is located in a range of 1 m to 2 m immediately below the identification information receiver 43, the identification information receiver 43 is set so that the reception of the identification information from the information providing apparatus 20 is not possible. Is set. Thereby, the distribution apparatus main body 41 can detect from the reception state of the identification information that the information providing apparatus 20 is located within a range of 1 m to 2 m immediately below the identification information receiver 43.

Here, for example, since Wi-Fi communication is omnidirectional, the information provision range cannot be limited. Moreover, the method of sticking the member which absorbs an electromagnetic wave on a wall and taking a countermeasure is expensive.

In contrast, in the fifth embodiment, inexpensive and directional infrared rays are installed at intersections, and information is provided by narrowing the elevation angle for each indoor passage. Guidance information is information which does not include map information and indicates a traveling direction and a traveling distance.

In such a guide information distribution device 40 and a user guide system, guide information is transmitted to the information providing device 20 from the guide information transmitter 42 installed at the intersection of the indoor passage using an infrared signal. . The guidance information includes travel distance information at the intersection. For this reason, it is not necessary to provide map information to the information providing apparatus 20, and inappropriate use of the map information in the management area can be suppressed.

Further, since the guidance information distribution device 40 receives the identification information from the information providing device 20 and sends the guidance information corresponding to the identification information to the information providing device 20, it sends more appropriate guidance information for each information providing device 20. Can do.

Further, the guidance information distribution device 40 transmits a request signal to the indoor passage, and the information providing device 20 transmits identification information in response to reception of the request signal. For this reason, it is not necessary for the information providing apparatus 20 to continue transmitting identification information, and the risk in terms of security can be reduced.

Moreover, the power consumed by the information providing apparatus 20 for communication can be reduced. In particular, when the information providing apparatus 20 is a mobile body that operates on a battery, it is important to reduce power consumption.

Further, the distribution apparatus main body 41 can detect the position of the information providing apparatus 20 from the reception state of the identification information. In particular, by using the identification information as an infrared signal, it is possible to detect the position with relatively high accuracy at a low cost. Wi-Fi can transmit information, but the position specifying accuracy is not good because it is non-directional.

In the fifth embodiment, the guide information transmitter 42 and the identification information receiver 43 may be integrated and installed at the same location on the ceiling of the intersection.

In the fifth embodiment, the intersection may include a waiting space in front of the elevator entrance / exit and the inside of the elevator car.

Also, in Embodiments 1 to 4, it is possible to transmit / receive identification information using infrared rays and guide information using infrared rays.

Further, instead of the above-described infrared communication, directional optical communication such as visible light communication or laser communication may be used.

For example, as a modification, a plurality of guidance lighting devices having a visible light communication function may be arranged along the passage.

¡If this guidance lighting device is installed at a position close to the floor surface, it is inconspicuous and not easily noticeable by humans, so it is desirable for maintaining an indoor landscape. Further, it is assumed that this guidance illumination device can only communicate with the information providing device 20 existing in the surrounding 1 to 3 m from the guidance illumination device.

Also, the guidance information display device 40 and the guidance illumination device may be output as guidance information indicating which distance and how much distance should be advanced from the base point.

Embodiment 6 FIG.
The above-described user guidance system indirectly provides necessary information such as a traveling direction and a distance without distributing the indoor map itself to the information providing apparatus in order to suppress unintentional outflow of the indoor map.

However, it is desirable to increase the amount of information provided to users for guidance information to pedestrians, etc., except for mobile devices such as robots that automatically move unattended. For this reason, it may be desirable that the display is an overhead view of the entire floor, not information on the traveling direction and distance.

The distribution control unit 12 according to the sixth embodiment creates and distributes guide information according to the type of information providing apparatus, that is, whether it is a robot or a person carrying it.

The information providing apparatus 20 according to the sixth embodiment notifies the guide information distribution apparatus 40 of type information indicating the type of the information providing apparatus. Upon receiving the type information, the distribution control unit 12 checks whether the type information is “robot”.

When the type information is “robot”, the distribution control unit 12 distributes the traveling direction of the robot and the traveling distance information as in the first to fifth embodiments. At this time, feature information that can be used by the robot to recognize the position and orientation, for example, image data, may be distributed together.

If the type information is not “robot”, the distribution control unit 12 checks whether the type information is “person”. If the type information is not “person”, the process ends. When the type information is “person”, the distribution control unit 12 creates guidance content based on the indoor map and distributes it to the information providing apparatus 20.

Guidance content is composed of facility names, icons representing each facility, appearance map data representing the appearance of the floor, and the like.

For the facility name, public attribute information indicating public or private at the time of display is given in advance to the map data. For the icon data, display position information is previously assigned to the map data.

For the appearance map data, the attribute information indicating the line for appearance and the appearance map data attribute information are assigned in advance to the line indicating the wall or boundary line of the map data. The appearance map data attribute information is information such as thickness, line type, and color at the time of display. The line type information is information such as a broken line and a solid line.

The image information generated using the appearance map data attribute information may be the appearance map data of the floor, or arbitrary guidance content prepared in advance may be included in the map data as appearance map data.

It should be noted that this guidance content is preferably interactive content that responds to input from a user who uses HTML5, Flash content, or the like in which icons function as buttons.

Also, it is desirable that this guidance content has a button that allows the user to search for the facility that the user wants to search with few steps.

For example, buttons with categories, such as rest lines, children's clothes, shoes, etc., are arranged on the screen. Then, the user of the information providing device 20 may touch the button to highlight the target facility or display the location floor and position of the target facility as text information. The highlighting includes, for example, a display that surrounds the target facility with a thick line, a display that blinks the icon of the target facility, and a display that adds a marker on the target facility.

If the facility displayed as guidance content is out of business hours, or if the business end time is likely to pass before arrival, an icon or text information indicating that the business hours of the facility will end may be displayed.

That is, it is desirable that the map data includes category information including product information handled by the facility and service information such as business type, and information on business hours.

In addition, it is desirable that the information providing apparatus 20 be provided with an input unit that can specify an arbitrary icon or facility name from the user, such as a touch panel, a button, and a voice recognition input unit.

According to such a configuration, the guide information distribution device 40 can provide the guide information to the user in an appropriate format according to the use purpose of the guide information.

In addition, conventionally, guidance content such as image data for performing facility guidance on a floor has been manually created individually without being automatically generated from map data. For this reason, the cost for producing the content for guidance according to the change of a facility or the change of a layout was required. On the other hand, in this embodiment, since the guidance content can be automatically generated from the map data, the cost for creating the guidance content can be reduced.
