Description

  The present invention relates to a route information management system, and more particularly to a route information management system for guiding a passerby who passes through public facilities such as indoor and outdoor pedestrian walkways, roads, and pedestrian bridges.

2. Description of the Related Art In recent years, geographical information including the location of major facilities and transportation facilities in a certain region has been provided through a mobile phone connected to the Internet (Patent Document 1). However, this information is public information for the general public, and the information that each user really needs is often not understood unless they go to the local area. Often people who call will get the information they need faster. For example, when you visit a store that is difficult to understand on a map, you will not get lost if you follow the directions of someone who has already been there. In addition, users who use bicycles or wheelchairs have a need to select a route with less unevenness or steps on the road surface, but if they can follow a route recommended by other users, they can easily reach the site. Furthermore, traffic safety can be ensured by storing and supplying information on dangerous locations such as steps that are inconspicuous in such routes to server devices on the network as warnings to users who come later.

  Here, conventionally, as a system for recording the travel route of another person, the location information transmitted from a transmitter installed at the entrance of a transportation facility such as a railway or at a transfer point is received and recorded by a card carried by the user. In addition, there is known a path information management device that reads the record with a receiver placed at the exit (Patent Document 2).

  As a means for guiding a route of a moving body, there is a car navigation system that uses a global positioning system (GPS) to show a shortest route to a destination on a map (Patent Document 3).

In addition, as a means for measuring the position of a moving body as a premise of route guidance and recording, an apparatus for performing three-point positioning using a short-range radio (such as Bluetooth) (Patent Document 4) and inertial navigation using an inertial sensor. An apparatus (Patent Document 5) is known. Furthermore, a device for measuring the position of a person by mounting an inertial sensor in a shoe has been proposed (Non-Patent Document 1).

    The system of Patent Document 2 is merely for recording a route when using a transportation facility, and cannot record a route when traveling through a city. Although the system of Patent Document 3 can guide a route through a city, there is an error of several meters in a stopped state, and it is difficult to reproduce a highly accurate route avoiding a dangerous level difference. It cannot be applied to other routes. Furthermore, although the devices of Patent Documents 4 to 5 can also measure the position of an object or a person who moves indoors, there is no idea of recording and managing the route of the moving body.

  Therefore, the present invention provides a system that can easily follow another person's route to the destination and provide route information with high added value, and has an interval over the entire length of the traffic route including the branch point. It is an object of the present invention to provide a system in which a number of position signers are provided, a route determined from a position signer passed by a passer-by is stored in a relay device, and supplied to other passers-by.

  The first means is an indoor or outdoor traffic in a route information management system for transmitting and recording route information between a plurality of position marking machines fixed in the middle of the route and a portable terminal for passers-by. A number of position marking machines 2 are installed at intervals over the entire length of the road S in the traffic direction, and these position marking machines 2 or terminals 10 are connected to a relay device 28 through an electric communication line N. Each terminal 10 is provided with guidance means for storing the order of the position marker 2 that the passer has passed as a route in the apparatus and indicating the path of the route left by another passerby.

  “Traffic road” refers to all passages through which people pass, such as pedestrian roads on both sides of a roadway, underground corridors, corridors and lobbies inside buildings such as department stores, libraries and office buildings. In many cases, this route has at least one branch point because of the function of this system for guiding a passerby, but the route is not necessarily limited to this. Even if it is a one-way sidewalk, for example, a visually impaired user (especially a blind person with a loss of vision) can be relieved if there is a system that guides them away from the sidewalk. It would be even more convenient if there was a system to be careful about dangerous parts such as steps. In addition, the direction of travel refers to the direction in which the road extends.

  The “position marker” is provided so that it can oscillate radio waves and infrared rays and record that at least a passerby has passed by the position marker. Each transmitter can be a wireless IC tag. As the communication technology, conventionally known Bluetooth, ZigBee, and IrDA (Infrared Date Association) can be used. Bluetooth is a wireless communication technology for morphological information devices, which connects notebook computers and mobile phones without using cables and exchanges voice and data. To use a frequency band (2.45 GHz) that can be freely used without a license, to be able to use even if there is an obstacle if the distance between devices is within 10 m, to use a small 0.5 inch square transceiver It has characteristics suitable for this system, such as low power consumption and low manufacturing cost. ZigPee is the same type of technology as Bluetooth, but it has lower transfer speed and shorter transmission distance than this, and is more power saving and lower cost. IrDA is a short-range communication standard using infrared rays, and the communicable distance is about 1 m.

  The position sign machine is provided along the city road as the city infrastructure. For example, if existing facilities such as telephone poles, streetlights, guardrails, etc. are used as installation locations, IC tags are simply attached to these facilities, so location signs can be attached to the main roads of the city within a reasonable cost. it can.

  The “relay device” may be, for example, an Internet server device.

  “Passers” mainly refers to pedestrians or wheelchair users or bicycle users.

  As the “guidance means”, conventionally known voice or visual guidance means may be used. For example, as is well known in car navigation devices, the position and orientation of the device are automatically recognized so that the actual geographical orientation matches the orientation on the screen. A mobile phone that has been configured to match is already adopted (Patent Document 6). Further, the guidance means is not necessarily limited to the guidance from the starting point of the route of the previous passer-by, but can be guided from any midway point of the route. As a result, the guidance function can be resumed from the interrupted point at any time even when the guidance is interrupted even if the user goes to the toilet in the process of following the route of the person.

  The second means includes the first means and measures the position of the position marker 2 in advance, and the position marker 2 is connected to either the position marker 2 or the terminal 10. Positioning means for determining the relative position of the terminal 10 with respect to is provided so that the position of the passerby on the road surface of the traffic path S can be determined.

  “Positioning means” accurately measures the position of the target (terminal) on the road surface using the conventionally known three-point positioning method or the like from the direction and distance of the target. For example, the relay device is formed by at least a pair of transmitters at regular intervals, and the relative position of the target object with respect to these transmitters is determined by the distance between the transmitters and the distance from each transmitter to the target. Good. As a means for measuring the distance, for example, it is common to receive the radio wave transmitted from one of the transmitters and the terminal on the other side and return to the other side at the same time and measure the distance in the time required for the round trip. . By using such positioning means, the position of the user on the road surface of the traffic road can be accurately grasped with an accuracy of about 1 m, for example. If three transmitters arranged at intervals from each other are used as positioning means, the three-dimensional coordinates of the target can be uniquely determined, which is more convenient.

  The coordinates of the transmitter and the terminal may be specified by absolute coordinates such as longitude and latitude, but may be specified by relative coordinates applied within a certain area. The latter can be applied in special areas such as the floor of one building. Further, for example, a combination of relative coordinates and absolute coordinates can be used inside and outside the building.

  The third means includes the first means or the second means, and stores the position information of the passer's own route on the route marked by the passer-by through the passer's terminal 10 in the relay device 28, and The position information can be taken out via the terminal 10 of another passerby.

  “Marking” refers to recording the coordinates of a place where there is a step or the like on the road on the relay device by operating the terminal. In addition, it can comprise so that comments, such as "with a level | step difference", can be attached | subjected with the coordinate information.

  The fourth means includes the third means, and the position of the passerby from the positioning point near one position marker 2 to the positioning point near another position marker 2 on the route, The inertial sensor 22 built in the terminal 10 is used for determination.

  The reason why the inertial sensor is used in combination to measure the position between the position marking machines is to save the number of position marking machines installed on the traffic path.

  If an inertial sensor is used, there is an error of about 10% of the walking distance. Therefore, in order to determine the position with an accuracy of 1 m, the position is about 10 m (or about 20 m when using the correction means of the fifth means). A sign machine should be installed. Conversely, if the position marker is installed at such an interval, sufficient accuracy can be obtained compared to GPS.

  The fifth means includes the fourth means described above, and the position information marked by the passerby from one position marker 2 to the adjacent position marker 2 is sent to both position markers 2. It is configured to be able to correct based on the coordinates of the measured point.

Specifically, when the movement time T until from one location indicator machine to another position indicator apparatus, the moving time from one location indicator machine until the marking locations and T _1, the inertia at the other position indicators The position error at the sensor may be Δe = (X, Y, Z), and the error at the marking location may be Δe × (T ₁ / T).

  The calculation based on the travel time is because the error in the positioning system that uses the inertial sensor to measure the position of the passerby is the most dominant time required to travel from the starting point. This is because the measurement error of acceleration accumulated per unit time is larger than the effect of walking speed and distance on error. In this specification, the “movement time” means the entire time used to move from a certain point to another point, and the time during which the vehicle has stopped halfway is counted. More specifically, assuming that the processing speed of the program routine of the microcomputer built in each position marker as the whole system is the same, the length of the movement time may be determined by the number of processing times of this routine.

  The sixth means includes the fifth means, and when a passer who passes the vicinity of one position marker 2 and a passer who passes the vicinity of another position marker 2 are encountered, The position coordinate of the passer with the longer travel time from the position marker 2 is corrected based on the position coordinate of the passer with the shorter travel time from the position marker 2.

  This means is to adopt the correct position information by transmitting the more reliable data of the position information of passing users to the other when the interval of the position marker cannot be made close. is there. The users who pass each other may be other people.

  The seventh means includes the third means to the sixth means, and the terminal 10 is an alarm means for issuing a warning when the passerby approaches a place that should not approach such as a dangerous place on the passage. It has.

  Ensuring the safety of places where people pass, such as roads and station premises, is important not only for users but also for those responsible for managing these facilities. As described above, according to this system, the position of a passerby on the road surface can be ascertained with an accuracy of about 1 m depending on the distance of the position marker. For example, the roadway and the sidewalk are not separated by a guardrail. When a person or a child is walking near the center of the road, he says, "I'm sticking out on the side of the roadway." It is better to issue a warning by voice or the like. Further, it may be configured such that the terminal vibrates to notify the danger for an elderly person with a long ear or a hearing impaired person.

The invention according to the first means has the following effects.
Since the route left by a certain passer-by is stored in the relay device 28 and output to the terminal 10 of another passer-by, the destination can be reached easily and reliably.
○ Route information such as small stores and alleys that cannot be put on a general map can be provided, and diversity of information can be secured.
○ Route information such as road construction and deterioration of road surface condition due to weather can be provided one after another, and it is possible to ensure the early information availability.
○ Unlike GPS, it can also be applied to indoor roads (such as condominiums at homes and station premises). For example, detailed route guidance from home to work can be provided.

  According to the invention relating to the second means, the positioning means for determining the relative position of the terminal 10 with respect to the position marker 2 is provided so that the position of the passerby on the road surface of the traffic path S can be determined. The route avoiding the stepped portion on the road surface can be recorded in the relay device 28.

  According to the third aspect of the invention, since the passerby can mark any point on the route, it is possible to warn other users of dangerous places on the route.

  According to the fourth aspect of the invention, the position of the passerby from one position marker 2 to another position marker 2 is determined by the inertial sensor 22 built in the terminal 10. Therefore, the initial cost can be reduced by saving the number of the position marker 2.

  According to the fifth aspect of the invention, the coordinates of the position information measured by the passerby from one position marker 2 to the adjacent position marker 2 are measured with respect to both position markers 2. Therefore, the position of the marking portion can be accurately measured while taking a certain distance between the position markers.

  According to the sixth aspect of the invention, when a passer who passes the vicinity of one position marker 2 and a passer-by who passes the vicinity of another position marker 2 are encountered, Since the position coordinate of the passer with the longer travel time is corrected on the basis of the position coordinate of the passer with the shorter travel time from the position indicator 2, there is more traffic and the position sign It is possible to improve the accuracy of positioning by using the position coordinates of passers-by even in places where the interval for installing the machine becomes wide (for example, an intersection or a plaza).

  1 to 6 show a route information management system according to the first embodiment of the present invention.

  This system includes a position marker 2, a user terminal 10, and a relay device 28.

  The position marker 2 is a device in which a pair of transmitters 4 and 4 using communication technology such as Bluetooth are installed at a certain distance. It is convenient that these transmitters are attached to the surface of the substrate 6 such as a label or seal for sticking to the target surface at a predetermined distance in advance. Each transmitter 4 is configured to receive a radio wave from the terminal 10 and send back a return radio signal.

  These position markers 2 are installed at an appropriate interval over the entire length in the passage direction of the outdoor or indoor passage S in the area to which the present system is applied. For example, it can be installed in roads of certain urban areas, passages of stations and underground malls, passages of various buildings such as office buildings, lobbies, and parks. In addition, as shown in FIG. 2, it is desirable that the position marker 2 is attached to a part of existing facilities such as a utility pole, street light, guardrail, and the like. However, it is also possible to embed as a fixed sign on a part of the road surface. The position marker 2 may be configured to receive a signal transmitted from a terminal device, which will be described later, and send it back simultaneously.

  The terminal 10 is formed by the main body 12 and the measuring unit 20. As shown in FIG. 1, a plurality of terminals 10 are connected to the Internet, which is a telecommunications line N.

    The terminal body 12 has an input button 14 and an operation screen 16 like a mobile phone, and preferably has the function of a mobile phone. The operation screen 16 is formed so that the route of another person can be displayed on the map and the current position of the user can be displayed. Further, the terminal main body 12 is provided with warning means (not shown) for notifying by sound or vibration when the user approaches a dangerous place. In addition, the terminal itself uses a communication function similar to that of a mobile phone, along with the personal identification number of the user carrying this machine, as well as various information about the route (the route itself, comments about the route, and the time passed through each point on the route Etc.), and the route of another user can be received.

  The measurement unit 20 is provided so as to be detached from the main body 12 and to be attached to a portion of the body that moves less. The measuring unit 20 includes an inertial sensor 22 and a short-range communication unit 24. The inertial sensor measures a path of movement from a specific reference point, and the short-range communication unit 24 uses the measuring unit and the position marker. The distance between each transmitter 4 is measured and the measured value is output to the terminal body 12.

  The relay device 28 is connected to the telecommunications line N, and each user's route data and mark data can be uploaded (input) and downloaded (output) to the data bank of the relay device 28 through the line. It is configured to be able to. In addition, the data bank stores personal information such as identification numbers, map data, facility information, position information of position markers, and other information related to routes collected from each user. Information about the route can be exchanged within the specific group that registered the member. Moreover, according to the content of information, for example, it can classify | categorize like information advantageous for an elderly person and information advantageous for a wheelchair user, and can take out for every specific area.

  In the relay device, route data and marking data are accumulated as discrete point data arranged at a very fine pitch as shown in the following table.

  In the table, Sign-a is the name of the position marker that serves as a reference for the relative coordinates Xn, Yn, and Zn. The time is displayed in units of 1 / 100th of a second.

  The absolute coordinates of each position marker are stored in the server's Sign table. In addition, “Q” in the table is marking information, and when this element is 0, it means that the route is not marked. The meaning of the mark “Q” (for example, the content of a warning such as “with unevenness”) is stored in the mark table of the server.

In the above configuration, when the own route is stored in the relay device of the system, the terminal is turned on and linked with the relay device of the system. At this time, the surrounding map information is downloaded, the map is displayed on the operation screen, and the route S where the support of this system is received, that is, the route where the position display device 2 is attached at regular intervals is confirmed. . This check is not necessary if all the roads in your area are supported by this system. When the user enters the traffic route S, the system measures the user's position and records the route according to the following procedure. That is, as shown in FIG. 2, when the user A who is passing the sidewalk crosses the side of the position marker 2 attached to the street light, the transmission of the terminal 10 carried by the user A and the position marker 2 Transmit and return radio signals to and from devices 4 and 4, measure each distance between each transmitter 4 and terminal 10 from the round trip time, and download from this measured distance and relay device 28 and a coordinate information of the transmitter of the position indicator unit is provided to be able accurately determine the user's location P ₁ carrying the terminal 10 by a three-point positioning method. Further, the path of the passerby from the place P ₁ until passing by the next position marker 2 is measured by measuring the acceleration by the inertial sensor 22. By the time the depression there is such a road pavement as the middle illustration, with walking to bypass the recess, the detour portion P ₂ marked by button operation of the terminal body 12, a comment the user coming later It is stored in the relay device 28.

  When starting from a point where the position marker is not installed, the absolute coordinate is not determined and the route from that point is recorded by the inertial sensor, enters the traffic route S and passes by the first position marker 2. At that point, the coordinates of the route up to that point can be determined retrospectively.

    Next, when tracing the route of another person using the system of the present invention, the terminal body 12 is operated to search and instruct the destination, and the route information and marking information to the destination are downloaded. . At this time, the route to the destination and the current position of the user may be displayed on the operation screen. If the current position and the route including the destination are separated and are not supported by the route information, move to an existing navigation method such as using the map on the operation screen to any point along the route Just do it. There is another route that intersects one route to the destination, and when you are near this other route, you can follow the other route to the intersection and change to the one route at the intersection. it can.

  In this way, it is possible to reliably reach the destination by following the route of the previous user recorded in the relay device, and to pass safely with reference to the comments.

  Next, a usage example of the present invention will be described more specifically with reference to FIGS.

  FIG. 5 shows the route until the starting user A reaches the destination 40 on the operation screen 16 of the terminal body 12. A exits the ticket gate 42 of the subway station C and tries to go to the ground through the underpass 44, but the nearest entrance 46 must go up the stairs. A decides to use the entrance / exit 48 with a lift (elevator) through the underpass 44, but with a slight detour, so that the user B who has injured his leg can easily walk with a cane. Here, marking is performed by operating the button of the terminal 10 in front of the elevator 48, and a comment “entrance / lift is present” is transmitted to the relay device 28. Furthermore, since there was a large depression 50 on the road surface at the second corner after exiting the entrance 48, A remarked here and left a comment such as "T-junction / recessed". Furthermore, A went too far without turning the corner that should be turned on the road ahead, so mark the alley that entered from that corner, leave a comment “Alley, go too far”, and pass this alley 52 And reached destination 40.

  FIG. 6 depicts a process in which the later user B reaches the destination 40 while following the route of A. B exits the ticket gate 54 of the subway station D, operates the terminal 10, and downloads the map information near the current position and the route information of A. When the user moves on the route A and activates the guidance function, the route ahead is displayed on the operation screen 16 even in the middle of the route A. In FIG. 6, the entire route from the starting point to the destination is displayed. However, as is conventionally known, a part of the route is enlarged, and the geographical environment on the screen advances toward the destination side according to the step of the user B. Can be configured to go on. B then goes to the ground via the doorway 48 and further bypasses the depression 50 according to the comment. Further, at the corner in front of the alley 52, when B ignores the route A and enters the alley 52, the terminal 10 automatically starts guidance to the next route from there. As a result, it is possible to follow the shortest route while omitting useless portions of the path of the preceding person A.

  FIG. 7 shows a second embodiment of the present invention. When marking a route portion between the position indicators 2-1 and 2-2, the positions of the marks α and β can be corrected. It is something that can be done.

Here, assuming that the calculation speed of the program routine for calculating the path using the inertial sensor 22 in this system is constant, the error in position measurement using the inertial sensor is considered to be approximately proportional to the number of calculation of the program routine. . Therefore, in moving from the position indicator unit 2-1 to the position indicator unit 2-2, N times the total number of calculations from the starting point, the number of calculations to Mark-α _{N a} of times, the number of calculations to Mark-beta N _b times.

Then, the accurate coordinates of the user in the position marker 2-2 are represented by (X _2t , Y _2t , Z _2t ), and the measured coordinates of the position marker 2-2 are represented by (X ₂ , Y ₂ , Z ₂ ). When the error in the position indicator unit _{2-2 (e x, e y,} e z) = (X 2 -X 2t, Y 2 -Y 2t, Z 2 -Z 2t) becomes.

Then, the position correction of Mark-α is as follows.
_{(X at, Y at, Z} at) = (X a -e x × (N a / N), Y a -e y × (N a / N), Z a -e z × (N a / N) )
Further, the position correction of Mark-β is as follows.
_{(X bt, Y bt, Z} bt) = (X b -e x × (N b / N), Y b -e y × (N b / N), Z b -e z × (N b / N) )
FIGS. 8 and 9 show a third embodiment of the present invention. In the case where the position marker 2 cannot be installed at an appropriate interval on the traffic path, instead of positioning based on the position marker, The position correction is performed using the coordinates recorded in each terminal between users who have come from different position markers.

  For example, in a large square, there are fences surrounding the square in the area around the square, and you can install position signers at appropriate intervals. This is a case where it cannot be secured. The same applies to the rotor square in front of the station and the shrine approach. In such a case, it is conceivable to store the position marker in a suitable protective case and embed it in the road surface. However, in this case, the cost becomes considerably higher than a case where it is simply attached to a utility pole or the like.

  In this embodiment, there is a possibility of encountering other users (whether or not they are acquainted) using this system in a place where there is a lot of traffic even in a space (especially a wide space) where it is difficult to install such a position sign. Pay attention to the fact that it is high, and send and receive mutual coordinate data, specifically, adopt the coordinate of the shorter travel time from the position marker as the other coordinate as the more accurate coordinate The content of that.

When a user A who has departed the position marker 2-1 and a user B who has departed the position marker 2-2 have encountered, when the number of calculations until the encounter is Na> = Nb, the position of B (X _b2 , Y position (X _a2 , Y _a2 , Z _a2 ) is corrected with Y _b2 , Z _b2 ) being positive.

  Here, the short-range wireless communication used by the terminals of the users A and B to recognize each other and exchange position information is a radio wave having no directivity (a radio wave spreading in a spherical shape). The maximum reachable distance (sphere radius) is R.

FIGS. 8 and 9 show positional relationships measured by the inertial sensors of the users A and B when the terminals of the users A and B recognize each other. In the drawing, the user A is located away from the circle with the radius R centering on the user B. However, since the terminals A and B actually recognize each other at this time, the user A is actually You must be on this circle. That is, the correction position (X _a2t , Y _a2t , Z _a2t ) of the user A is a sphere whose radius is R with (X _b2 , Y _b2 , Z _b2 ) as the center, and (X _b2 , Y _b2 , Z _b2 ) and _{(X a2, Y a2, Z} a2) and out of the intersection of the straight line passing through _a point close to the _{(X a2, Y a2, Z} a2).

Where L = [((X _a2 −X _b2 ) ² + (Y _a2 −Y _b2 ) ² + (Z _a2 −Z _b2 ) ² )] ^1/2
Then, the correction position [X _a2t , Y _a2t , Z _a2t ] of A is given by the following equation.

[X _a2 t, Y _a2 t, Z _a2 t] = [((X _2b + (X _2a −X _2b ) × R / L), (Y _2b + (Y _2a −Y _2b ) × R / L), (Z _2b + (Z _2a −Z _2b ) × R / L)]
In the present embodiment, information is basically exchanged regardless of the user's intention. Therefore, it is desirable not to transmit route information (starting point or destination) other than the position coordinates of the encounter place. .

  FIG. 10 shows an embodiment of the present invention. In this embodiment, in order to secure a route for the wheelchair user B to go to the destination, the route information of the predecessor A and the geographic information of the area opened in the present system are used.

  First, in order to confirm the geography from B's home 58 to the destination station 60, A calls the geographic information of the area on the terminal 10. This geographic information is the map data with information on traffic and security in the vicinity of the station and its surroundings (comments enclosed in double frames in the figure), and associations such as neighborhood associations can access the shopping street in front of the station. It is collected and made available to the public for local revitalization and citizen services. Looking at these data, the shortest geographical course from home to the station has a long waiting time, and the road surface is also uneven. Therefore, A selected a detour that has a pedestrian bridge with a slope and a barrier-free toilet even if it is a little far away, so that it can pass relatively safely and comfortably. And A decided to pass this detour in accordance with the commuting time zone in which B uses this route. Then, even on a detour with low traffic volume, a point that crosses the school road and requires attention to contact with the bicycle or a point with a small step is found. Commented on the matter. Furthermore, at the station 60, the position of the lift lift 62 with a slope was confirmed. In addition, A confirmed that there was a space in the toilet that could be used with the wheelchair. By following the route confirmed by A in this way, B can travel to the station comfortably.
