Description

Smart block guidance system for the traffic weak {SMART BLOCK GUIDE SYSTEM}

The present invention relates to a smart block directions system for the traffic weak.

A technology for providing walking guide information so that a user can reach a desired destination using a portable terminal such as a smart phone or a tablet PC is becoming increasingly common. The walking guidance system receives destination information from the user, identifies the user's location using a GPS sensor, and displays the searched route information on the screen of the terminal or outputs it as a voice. Since walking guidance information is provided based on visual or auditory information, even visually impaired persons who cannot receive walking guidance information through images such as maps can conveniently use it.

However, in the case of providing walking guide information based on the time of day, the use of the portable terminal during the movement leads to insensitivity to the surrounding situation and increases the probability of an accident because the surrounding danger cannot be detected. Therefore, in the case of providing walking guide information based on the time of day, the user is inconvenient in having to check the walking guide information displayed on the portable terminal while the movement is stopped.

In addition, when walking guide information is provided based on hearing, it is very inconvenient for the visually impaired and the hearing impaired to use it. In addition, when walking guide information is provided using earphones, etc., the risk of accidents increases because the sound of surrounding car horns cannot be heard.

In addition, since blind people cannot recognize surrounding information through sight, when a blind person moves, information about the ground of the movement path is obtained using a cane for the blind, or braille blocks constructed on a pedestrian crossing or a pedestrian path. Braille boards attached to stairs or entrance walls are used to enable people to move while obtaining information about their surroundings.

However, it is very difficult to identify the exact path of movement using only a cane in a state where objects cannot be identified, and even if a Braille block is installed or a Braille plate is attached, it takes a considerable amount of time to find the actual Braille block and Of course, it is not easy to find, so the utility is very low in case of receiving a directions service or an emergency situation.

Recently, the area of the Internet of Things (IoT), which is called the food of the future and the core of the trend, is expanding. In particular, with the spread of smart phones, personalization of IT is spreading, and accordingly, various contents are being released through interlocking with various home appliances and various smart devices.

In particular, due to the development of wireless communication technologies such as Wi-Fi and Bluetooth, various information may be collected or monitored using mobile devices and smart devices in various places. For example, in the case of Bluetooth, which is one of short-range wireless communication, a pairing process was required between devices in order to use Bluetooth. Since such a pairing process consumes power continuously, it is difficult to use it for a long time in a mobile device having a battery.

However, recently, mobile devices or smart devices that support Bluetooth smart and Bluetooth Low Energy (BLE) can transmit information between devices without a pairing process, and transmit data compared to the existing Bluetooth method. Since the cycle is long, power consumption is relatively small. In addition, since the manufacturing cost of mobile devices is low, it can be used as a Bluetooth beacon that provides various information for various purposes.

These Bluetooth beacons can be installed in a desired location and easily accessed through a Bluetooth-enabled mobile device or smart device that can be used without a pairing process, and is used in various fields with various information provided from the Bluetooth beacons at the installation location. It is possible.

In addition, when a user needs to change direction, a change of direction notification may be provided to the user.

3 is a diagram for explaining a directions service based on a smart braille block system according to an embodiment.

Referring to FIG. 3, a map 500 showing a user 510 and braille blocks 522 to 528 disposed on a movement path of the user 510 is shown.

For example, the map 500 shown in FIG. 3 may represent the interior of a subway station, but is not limited thereto. In addition, the braille blocks shown in FIG. 3 may each include a beacon terminal, but a beacon terminal may be included in a braille block corresponding to a predetermined interval or a specific event.

In an embodiment, the server 400 may determine the location of the user 510 based on information received from the user terminal 300. The method of determining the location of the user 510 is not limited, for example, comparing beacon signals corresponding to each of several braille blocks received from the user terminal 300, but corresponding to the beacon signal having the largest RSSI value. It may be determined that the user 510 is located within a predetermined range from the braille block.

Also, as a method of determining the location of the user 510, methods of determining the location of the user 510 based on the strength of a GPS signal or a Wi-Fi signal received from an AP may be used, but are not limited thereto.

In one embodiment, the server 400 determines the location of the user 510, determines the current moving direction of the user 510, and provides directions information to the user based on the moving direction of the user 510. I can.

For example, when the user 510 is located in a straight section, the server 400 guides the user 510 to continue going straight, and obtains information about an intersection, a crossroad, a staircase, a dead end, or a point where direction change is necessary in advance. Guidance may be provided to the user 510.

In addition, the server 400 may obtain destination information from the user 510, generate route guidance information for guiding the user 510 to a corresponding destination, and provide route guidance information to the user.

In addition, the server 400 may obtain information on a section, an object, an event, etc. around the user 510 based on the location of the user 510 and provide the information to the user 510.

In an embodiment, the server 400 may obtain one or more section information included on a route corresponding to the route guidance information. For example, section information may be determined based on the type of the at least one braille block and at least one object included in the path.

For example, the section information may be determined by a space in which linear braille blocks are continuous, that is, the section may be separated by point-shaped braille blocks. For example, when linear braille blocks are continuous, the corresponding section can be determined and classified as a straight section, and when a point-shaped braille block appears, the direction is changed or there is a crossroads, so it can be classified as a new section later.

As another example, section information may be classified based on various objects such as stairs, toilets, elevators, obstacles, pillars, and stores. For example, in the case of a subway station, if there is a staircase on the path, the steps before the staircase are classified as one section, the staircase is classified as another section, and the path after the staircase is classified as another section.

Accordingly, the server 400 may determine the location of the user terminal and determine a section in which the user terminal is located.

The server 400 may obtain information on a next section of the section in which the user terminal is located, and transmit the information on the next section to the user terminal.

For example, the section in which the user terminal is located, that is, the section in which the user 510 shown in FIG. 3 is located, and the next section in which the user 510 is located is a section in which the user 510 is located is a section in which the next section is rotated to the right, a staircase, or a cross-section By providing information such as, such as, in advance, the user 510 can prepare in advance for walking in the next section.

Also, the user terminal may output information on the next section of the user 510 according to the location of the user terminal based on information received from the server 400 or based on a processing result of itself.

In an embodiment, the server 400 may obtain information on a destination to which the user intends to move, and generate a route for moving to the corresponding destination. In generating a route, the server 400 may obtain information on a route on which the braille block is placed, and generate a route through which the braille block is placed to the destination.

In one embodiment, in guiding the user 510, the server 400 provides a guide for the user 510 to advance when the linear braille block 522 is recognized, and the next point-shaped braille block 524 The distance information to is obtained or calculated, and information about the distance to the next point-shaped braille block 524 may be provided to the user 510.

In addition, when the user 510 reaches the dot-shaped braille block 524, information for causing the user to rotate to the right may be provided.

In one embodiment, the server 400 generates a movement path of the user, but the information on the movement path may include only information on a braille block to which the user should change direction.

In this case, the capacity of information on the movement path may be reduced, and thus, there is an advantage in that information can be transmitted quickly. For example, when the user 510 wants to go to the destination 530, the server 400 may determine the location of the user 510 and transmit information on the braille blocks 526 and 528 to the user terminal.

In this case, the user terminal 300 guides the user 510 in the direction of the braille block 526, and when the user 510 reaches the braille block 526, the user terminal 300 guides the user 510 in the direction of the next braille block 528. When 510 reaches the braille block 528, it may be guided to move to the destination 530 by moving to the left.

In one embodiment, changes may occur in the actual site. For example, obstacles that did not exist in the past may occur, facilities may be damaged, roads may be damaged, and facilities may be newly constructed or closed.

In one embodiment, when a change occurs in the site where the one or more braille blocks are arranged, the information on the change is included in the beacon module of one or more braille blocks located within a predetermined range from the position corresponding to the change. Can be saved.

For example, a worker at a corresponding location may use a worker terminal to communicate with a corresponding beacon terminal to store new information.

In one embodiment, when the information on the change is received through the user terminal 300, the server 400 compares the information stored in the server 400 with the information on the change, and the change When the information on is different from the information stored in the server 400, the information stored in the server may be updated.

In one embodiment, when the information on the change is received from the wand, the user terminal 300 compares the information on the change with the directions information received from the server 400, and the change When the information on the matter and the directions information are different, the directions voice may be output based on the information on the change.

That is, even if there is information received from the server 400, when site information different from the corresponding information is received, the user terminal 300 may prioritize the site information and provide guide information to the user.

In an embodiment, the user terminal 300 may perform a method for specifying a section in which the user 510 is located.

In an embodiment, the user terminal 300 may obtain one or more beacon signals received by the wand and obtain an RSSI value of the one or more beacon signals.

In an embodiment, the user terminal 300 may determine one or more candidate sections in which the user terminal is located based on the RSSI value of the one or more beacon signals.

In an embodiment, the user terminal 300 may determine that the user terminal 300 is located in a candidate interval with the highest score calculated based on the RSSI value of the one or more beacon signals among the one or more candidate intervals. have.

For example, a beacon signal received from each beacon terminal may include information on a section to which the corresponding beacon terminal belongs.

Accordingly, the user terminal 300 acquires section information included in different beacon signals, and specifies the section to which the user 510 belongs based on the RSSI value of the beacon signals received from beacon terminals belonging to each section. can do. For example, it may be determined that the user 510 belongs to a section in which more signals with a large RSSI value are received, and a method of calculating a score for this is not limited, but, for example, the following method may be used. have.

In an embodiment, the user terminal 300 may calculate an RSSI value received from each beacon signal by scoring it, and may calculate a score range of 0.0 to 1.0 using an RSSI value corresponding to each beacon signal.

In an embodiment, the user terminal 300 may process 0.0 as an invalid value. In addition, 0.6 to 1.0 can be corrected to 0.5. For example, these values can be regarded as co-located signals because the actual RSSI value is less than -50.

As a result of the above processing, beacon signals may be grouped by a score of tens.

The user terminal 300 may count zone grouping for each score zone and count the number of beacons in the same zone for each score zone.

If there is only a single zone in the same score band, the user terminal 300 may determine the corresponding zone information, and if other zones exist in the same score band, the user terminal 300 may determine the zone by summing the beacon values having the largest value of each zone.

In one embodiment, the user terminal 300 obtains information on the type of braille block corresponding to each of the one or more beacon signals, and based on the RSSI value of the beacon signal corresponding to at least one dot-shaped braille block and its change. Thus, the position and direction of at least one branch point can be determined.

The user terminal 300 may output information on the location and direction of the branch point. That is, the user terminal 300 can determine the location of the user based on the RSSI values of the beacon signals received from the wand 200, even when there is no determination of the server 400, as well as the surrounding point-shaped braille blocks. Recognizes and can judge its distance. Based on this, the user terminal 300 may provide information on the location of the point-shaped braille block to the user, thereby guiding the user to change direction or respond to other objects, events, etc. in advance.

In an embodiment, the user terminal 300 may provide feedback to the wand 200. For example, when it is recognized that the pattern of the braille block located in front of the user is a pattern that advances five blocks and then turns right, the user terminal 300 transmits the information to the cane 200 and the cane 200 Can transmit the information to the user by voice or vibration.

For example, in the case of transmitting information by vibrating, if it vibrates five times and then turns right, it can vibrate twice briefly, if it turns left, it can vibrate three short times. It may be slightly shaken with, but this is not limited.

As another example, the wand 200 may notify the user through vibration when the point-shaped braille block is located within a predetermined distance on the user's path. In this case, the user can easily receive information from a noisy place or outside through vibration, and can prepare in advance for changes in the path.

In addition, the wand 200 may provide information on a change on a path through vibration. According to an embodiment, the wand 200 may vibrate in a preset pattern to provide information to a user.

In one embodiment, the wand 200 transmits a beacon signal received from a beacon terminal of different braille blocks to the user terminal 300, and the user terminal 300 may specify the user's location based on this.

For example, different identifiers (IDs) may be assigned to each beacon terminal, and such identifiers may be included in the beacon signal. Accordingly, the user terminal 300 may determine that the user is located at a location corresponding to the identifier of the strongest beacon signal.

As another example, the user terminal 300 may calculate a predetermined position determination reference value based on information received from different beacon signals and each beacon signal. The user terminal 300 may determine a location on a map corresponding to the location determination reference value, and the location determination reference value calculated at each location may be measured in advance, matched on the map, and stored. The user terminal 300 may determine that the user is located at a location where the location determination reference value calculated on the map matches. That is, since the beacon signals measured at each location and the strength of the signal will be different according to the arrangement of the braille block, the position determination reference values calculated at each location will be different from each other. Accordingly, the user's location can be accurately determined based on the location determination reference value. In this case, there is an advantage of being able to accurately determine the location of a user in a location where the braille block is not placed.

In this case, when it is determined that the user is in a place where the braille block is not placed, the user terminal 300 provides guide information for guiding the user to move to the location where the braille block is placed based on map information or received beacon information. Can be printed.

In one embodiment, the server 400 collects information received from a plurality of user terminals 302-306, and may update changes or additional information for each location based on the collected information.

In addition, the server 400 builds big data collected from a plurality of user terminals, corrects incorrect information based on this, and analyzes the movement patterns of different visually impaired people to improve safety and convenience of the visually impaired. Guide information can be created and provided.

In addition, when a new facility is built or a facility for the visually impaired is supplemented, a system that enables the safety and convenience of the visually impaired to be improved based on the built big data can be built.

In an embodiment, the server 400 may transmit information provided from the user terminal to the external server 600.

For example, the server 400 shares information obtained from user terminals with a server that manages public transportation (bus, subway, taxi, etc.), so that the visually impaired people are provided with public transportation information conveniently You can support to use transportation. In addition, the server 400 may provide a service such as pre-reserving a taxi according to the time when the blind person leaves the subway station by providing information to an external server.

In one embodiment, the user may request help by using the cane 200 or the user terminal 300 when the user needs help or is in an emergency situation. In this case, the server 400 may transmit the request information to the external server 600 in order to transmit the request information to other users such as fire departments, hospitals, and guardians.

For example, the user may transmit the request information using the wand 200 or a button (including a physical button or a button on a touch screen) provided on the user terminal 300.

As another example, the user may generate request information using the motion of the wand 200. For example, the user moves the end of the cane 200 in a circular or 8 shape, or hits the end of the cane 200 against the floor a predetermined number of times, and is matched to each motion in advance. The present request signal may be transmitted through the user terminal 300.

In one embodiment, the wand 200 may be provided with a motion sensor or a shock sensor for detecting motion in advance. As another example, the user terminal 300 may determine the motion of the wand 200 based on a change in a beacon signal received according to the motion of the wand 200. For example, while acquiring information on a change in the intensity of a beacon signal received from a specific braille block or a plurality of braille blocks, the RFID provided in the wand 200 according to the change in the intensity of the beacon signal received from each braille block The moving direction and speed of the receiver can be calculated. The user terminal 300 may determine the motion of the wand 200 based on the calculation result.

In this case, the location information of the user can be transferred to an external organization to rescue the user. In addition, the user may transmit additional information about his or her state, and accordingly, information useful for the user's structure may be transmitted in advance. For example, information may be transmitted through a user's voice, but is not limited thereto.

In addition, the server 400 may receive various safety information and guide information corresponding to the user's location from the external server 600 and provide it to the user terminal 300.

For example, the server 400 may provide the user terminal 300 with arrival information of public transport, information about the distance from the platform, etc., and also the current location information of the user, information on facilities around the user (for example, , Various information about the presence or absence of stairs, the height and number of stairs, the location of obstacles, etc.
