Figure 1 shows the overall configuration of the route guidance system according to the present invention.

The present invention aims to collect location information through an RFID (Radio Frequency IDentification) system, calculate a route to a destination based on the location information, and guide the user by voice. Here, the RFID system refers to an automatic recognition technology through radio frequency recognition, and is mainly composed of an RFID reader and an RFID tag, also called a transponder, while a predetermined ID is transmitted while the reader's antenna emits radio waves. And when the RFID tag is stored in the magnetic field and other information is activated and transmits the ID and other information owned by the reader to the reader through the antenna, the reader operates by converting the received signal into predetermined data. With this principle in mind, the route guidance system of the present invention will be described in detail.

First, the RFID tag 110 is mounted on various objects installed at certain distances on a sidewalk for human traffic, that is, a sidewalk block, a power pole, a street lamp, a signboard, and the like, as the RF reader approaches. It is responsible for providing predetermined position information previously stored to the RF reader. Herein, an embodiment in the case of being mounted on a braille footpath block among the various objects, particularly for the blind, will be described. For reference, Figure 2 shows the internal configuration of the RFID tag 110 of the route guidance system of the present invention as a block, Figure 3 shows a structure in which the RFID tag 110 is mounted on the sidewalk block.

The RFID tag 110 is a memory unit 111 for storing the location information of the location where the tag is located, and the RF communication module 112 and antenna 113 for transmitting the stored location information as the RF reader approaches within a predetermined distance. In this case, it is preferable that the memory 111 and the RF communication module 112 be implemented as a micro one chip. Therefore, the micro one chip is mounted between the top plate 101 and the bottom plate 102 of the sidewalk block to prepare for the impact from the outside, the antenna 113 is the top plate 101 of the sidewalk block so that the electric field effect can be maximized ) And the lower plate 102 are preferably mounted in the form of an inlay of overlapping quadrangular or circular shape with one end concentric and one end cut off. In addition, the micro one chip and the antenna is preferably waterproofed with a material such as PVC compressed vinyl.

Next, the path detector 120 primarily plays a role of receiving location information from the RFID tag 110 and delivering the location information to the portable terminal 130. The direction of the current path detector is to determine the direction to guide the voice, the RF reader mentioned in the description of Figures 2 and 3 refers to the path detector 120 here. In this embodiment, it is assumed that a cane for the visually impaired person is used as the path detector, and a detailed internal configuration will be described below with reference to FIG. 4.

The path detector 120 may include an RF reader unit 121 for receiving location information from an RFID tag, a communication interface 124 for performing data communication with the portable terminal 130, and location information received through the RF reader unit.

In the latter case, the controller 125 drives the electronic compass 127 to determine the current direction when the user inputs a direction command of the current direction, and outputs the current direction as a voice through the speaker 128. It should include more.

In addition, each time the position information is received from the RFID tag 110, the control unit 125 may further include a function of driving the electronic compass 127 to determine the current direction and transmit it to the portable terminal. The current direction information thus transmitted helps the portable terminal to perform a more specific route guidance considering the current user's moving direction together with the position information of the RFID tag 110.

In addition, the RF reader 121 includes an RFID receiving module 122 and an antenna 123 for receiving location information from the RFID tag 110. In addition, the path detector 120 includes an RFID tag ( Various functions for smoothly driving the path detector 120 such as a memory unit (not shown) for temporarily storing the position information received from the 110 and a power unit (not shown) for supplying power to the respective components. It includes a configuration by default.

In addition, the communication interface 124 may be implemented by wired or wireless communication. In general, assuming that the path detector 120 and the portable terminal 130 are spaced apart from each other, a short range wireless device such as Bluetooth or IrDA may be used. More preferably implemented in communication.

Meanwhile, the path detector 120 may be implemented as belongings such as a wallet, a ballpoint pen, glasses, a necklace, or the like, or may be implemented in a manner that is embedded in the portable terminal 130 for calculating a path, but is not limited thereto. However, as described above, the present invention intends to implement a cane type in particular in view of the visually handicapped or the elderly. In the following, the present invention will be described with reference to FIG. do. 5 is a perspective view of one embodiment when the path detector 120 is implemented as a cane.

As shown here, the components except for the antenna 123 such as the RFID receiving module 122, the communication interface 124 and the control unit 125 are provided in the handle portion of the stick, the antenna 501 is a circular shape at the end of the stick It is preferably formed in the form of an inray (Inray) and is connected to the RFID receiving module 122 through the rod portion of the stick so that the maximum field effect occurs.

In addition, when the path detector 120 is provided with an input unit 126 for giving a current direction command, such an input unit 126 is a thumb formed in the handle portion of the cane as can be seen in the embodiment shown in FIG. Part of the groove for gripping is implemented as a button 601 so that the wand is always facing each time the user releases the wand.

Next, when the user's route guidance command is input, the portable terminal 130 primarily calculates a route to a destination and guides the user by voice. It is responsible for providing various information by voice.

The portable terminal 130 includes a memory 131 in which a geographic information program 131-1 and a geographic information DB 131-2 are stored for searching and guiding a movement path, and a geographic information program 131-1. And a communication interface 133 for performing data communication with the path detector 120 and receiving location information therefrom.

Here, the geographic information program 131-1 is a destination input module 11 for receiving a destination from a user, and a destination input to the destination input module 11 with the location information transmitted from the path detector 120 as a starting point. It consists of a path search module 12 for extracting the movement route to the destination point from the geographic information DB 132 through a predetermined algorithm, and a voice guidance module 14 for outputting the extracted movement route as a voice. Whenever the location information is transmitted from the path detector 120, the information program 131 analyzes whether the corresponding location exists on the extracted moving path, and if the location is out of the moving path, the new path using the recently received location information as a starting point. Path rescan module 13 for searching for may be further included.

In addition, in view of the present invention is mainly conceived in consideration of the visually impaired, the destination input module 11 of the geographic information program (131-1) is a voice recognition for converting into a text by receiving a route guidance command from the user by voice It is preferably implemented in modules.

In addition, the voice guidance module 14, when the user accesses a particular sidewalk block and the path detector 120 receives the position information from the RFID tag 110 mounted on the sidewalk block, the position information from the path detector 120 When is transmitted is preferably implemented in a way to guide the direction to be moved forward after confirming the location in advance to calculate the movement route. In this case, the user said, "You are in ○○○. From here, move 40 meters north and go to △△△." The announcement is output, and the user first grasps the current moving direction through the path detector 120 and then moves to the right (if the current direction is west).

In addition, the voice guidance module 14 accesses a particular sidewalk block, the path detector 120 receives the location information from the RFID tag 110 mounted on the sidewalk block and simultaneously drives the electronic compass 127 When the current direction at the point is determined, when the location information and the current direction information are transmitted from the path detector 120, the current direction is determined as the direction to be moved forward after confirming the corresponding position and the current direction in the previously calculated moving path. In consideration of this, it may be implemented to guide the voice. In this case, a message is output to the user, such as "The current position is ○○○. (Since the current direction is west.) Move 40 meters to the right and go to △△△." The user operates the path detector 120 separately. There is no need to know the current direction.

Meanwhile, the route guidance system of the present invention may further include a profile server 140 for providing a customized geographical information DB to a portable terminal of a specific user and / or a content server 150 for providing region-related contents of a specific point. have.

That is, the profile server 140 may search for profile DB 141 and path search that store personal information such as names and addresses of a plurality of users, and information about a movement pattern of a user, such as a place frequently visited and a place of accident history. While maintaining the geographic information DB 142 including various geographic information, guide voice information, etc. necessary for the mobile communication network, the geographic information DB 142 extracts only a specific part related to the profile of the specific user and the movement pattern of the user. Or the Internet or the like transmits to the portable terminal of the user through a communication network.

Therefore, the portable terminal 130 in this case should further include a wireless communication unit 134 for wireless data communication with an external server through a predetermined communication network, the geographic information program 131 of the portable terminal 130 The pattern collecting module 15 for collecting a moving pattern, such as a place where the user frequently goes, a place with an accident power, and transmits to the profile server 140 should be further included. Here, the wireless communication unit 134 may be implemented as a mobile communication module supporting a mobile network communication such as CDMA, WCDMA, or a data communication module supporting wireless Internet communication. The portable terminal 130 employing the same may be a cellular phone or a PCS. A phone, a PDA phone or an internet phone can be used.

On the other hand, while the content server 150 maintains a local content DB 151 for storing local content such as weather, news, specialties, tourism information, etc. of a specific region, when location information is transmitted from a specific portable terminal 130 Local-related content corresponding to the location information is extracted from the local content DB 151 and provided to the portable terminal 130 through a communication network.

Therefore, the portable terminal 130 in this case also needs to further include a wireless communication unit 134 for wireless data communication with an external server through a predetermined communication network, the geographic information program 131 of the portable terminal 130 It should further include a location notification module 16 for transmitting the location information received from the path detector 120 to the outside, and the voice guidance module 14 of the geographic information program 131 is transmitted from the content server 140 It should further include a function of outputting the received region-related content by voice.

Now, a specific embodiment of the process for the visually impaired person seeking a specific destination through the route guidance system having the above configurations will be described in detail with reference to FIGS. 8 to 10. FIG. 8 is a flowchart sequentially showing the operation of the route guidance system of the present invention, FIG. 9 is a layout view of an RFID tag on a road for explaining the embodiment, and FIG. 10 is a location stored in a specific RFID tag. A structural diagram of one embodiment of information.

It is assumed that the user starts to use the route guidance system at the branch point ③ of FIG. 9. When the path detector is activated and the geographic information program of the portable terminal is executed, the path detector receives the location information from the RFID tag installed in the braille sidewalk block at the branch point 3 near to the portable terminal (S801). At this time, the received location information is from the ID (1001) of the sidewalk block, the name of the sidewalk block (1002), the ID and distance (1003) of the sidewalk block located closest to the north from the sidewalk block, from the sidewalk block ID and distance of the sidewalk block nearest to the south (1004), ID and distance of the sidewalk block nearest to the east from the sidewalk block (1005), nearest to the west side from the sidewalk block It contains the ID and distance 1005 of the sidewalk block.

Subsequently, when a voice such as "Dangsan Station" or "Dangsan Station Guide" or "Route Guide"-"Dangsan Station" is input to the portable terminal to instruct route guidance to a specific point (803), the geographic information program of the portable terminal is described in the above. Based on the position information received at the branch point 3, the branch point 3 is regarded as the current position and is set as a starting point, and the corresponding position information (ID value of the RFID tag of the ticket gate of Dangsan station ⑥) to go to the voice input "Dangsan Station". Search and find the geographic information DB and set it as the arrival point. Then, the moving path between the starting point and the arrival point is extracted from the geographic information DB through a predetermined path search algorithm (S805).

The geographic information program voices the direction to be moved at the branch point ③ which is the current point among the extracted movement paths by voice, and the user starts moving accordingly. When the RFID tag of the next point (the branch point ⑤) is received during the movement and the position information is received from the RFID tag, it is checked whether the position information is included in the calculated movement path to check whether the position is correctly moved (S811).

If it does not move correctly and goes to the wrong point, the navigation path is re-searched using the branch point ⑤ as a new starting point (S813), and the process is repeated from step S811.

If you move correctly and reach the ⑤ branch, you will receive a voice prompt, "There is a Dangsan station ticket gate (the branch ⑥) in the west 30 meters ahead." In this case, in the case of receiving the current direction information through the electronic compass in addition to the position information of the branch point ⑤ in step S811, whether the position information is included in the calculated movement route and whether the current direction is appropriate for the movement route. You can also check to see if you are moving correctly. If you are moving correctly, the current user is facing north, so in consideration of this, "Tangsan Station ticket gate (junction ⑥) is located 30 meters in the left direction." You will be guided.

In the case of receiving the former voice guidance, the future direction of movement is west, but the current direction of movement may be wondering. On the other hand, in addition to receiving such a route guidance, there are times when you want to check the current direction of movement. At this time, the user can press the button provided on the handle of the path detector to command the current direction guidance (S815), the path detector drives the built-in electronic compass to determine the current direction and "The current direction is west. In the same manner as the "through the speaker to inform the user (S817).

If it moves correctly and reaches the branch point ⑤, the location information received from the RFID tag of the sidewalk block is transmitted to the content server through the portable terminal, and the content server receives the predetermined local information content corresponding to the received location information. The mobile terminal transmits the information to the portable terminal (S819), and the portable terminal receives the corresponding content as a voice such as, "At the point ⑤, the charity fundraising event is underway at present." (S821).

On the other hand, if the correct movement to reach the junction ⑤, the location information received from the RFID tag of the sidewalk block is transmitted to the profile server through the portable terminal, the profile server stores the location information as the movement pattern of the user After managing and managing the personal information of the user, the mobile terminal by extracting only the location information related to the movement pattern and personal information from the location information DB according to a predetermined period or the user's request and transmits it to the portable terminal of the user Keep only the local information for this user's usual location.

In this manner, steps S807 to S821 are repeated until the final destination is reached, and when the destination is reached (S823), the route guidance of the geographic information program is terminated.

As described above, the present invention has been described using embodiments, but these embodiments are merely exemplary, and those skilled in the art may make various modifications and changes without departing from the spirit of the present invention. I can understand that. In particular, the input unit 126 of the path detector 120 is an additional button for giving the portable terminal 130 various commands related to route guidance, such as destination input, route re-search, listening to local content, in addition to the button for the current direction guidance command. Buttons may be further provided, and these buttons are preferably separated by Braille for the blind.

According to the present invention having the configuration as described above, the current position through the cane-type path detector equipped with an RFID tag and an RF reader mounted on sidewalk blocks around the road, the voice to route to the destination through a portable terminal Because they can be guided, the visually impaired can set their own destination without the help of guide dogs. In addition, even when the visually impaired person is wondering which direction he is moving while moving to a destination, the electronic compass built in the path detector can check it at any time.

On the other hand, since the optimized geographic information DB can be maintained according to a behavior pattern of a specific visually impaired person, such as an activity range and a frequently visited place, the memory of the portable terminal can be efficiently used.

In addition, as the user reaches a specific location, the local content such as local specialties, festivals, news, weather, etc. for the local area is automatically provided through voice, thereby providing rich information to the visually impaired in addition to the simple route guidance. .
