1 is a view for explaining a bus guidance system related to the riding of the weak in traffic according to an embodiment of the present disclosure. Referring to FIG. 1 , the bus guidance system may include a terminal for the disadvantaged in transportation 100 , a bus terminal 200 , and a stop terminal 300 .

The transportation-disabled person terminal 100 may be a public remote control for operating the voice guidance device as a terminal device possessed by the transportation-disabled person, and may be a smartphone in which an app for operating the voice guidance device is installed. The transportation-disabled person terminal 100 may communicate with the bus stop terminal 300 within a predetermined distance. The stop terminal 300 may be a terminal installed at a bus stop. When the transportation-disabled person terminal 100 transmits an information request signal to the stop terminal 300 , the stop terminal 300 may transmit an information request signal to the bus terminal based on the received information request signal.

Meanwhile, the bus stop terminal 300 may maintain an inactive state in a normal standby state (idle state).

The traffic-disabled person may move to a bus stop where the stop terminal 300 is installed, and input an activation command of the stop terminal 300 to the traffic-impaired terminal 100 . When receiving an activation command from the traffic-impaired within a predetermined distance from the stop terminal 300 , the traffic-impaired terminal 100 may transmit an activation signal to the stop terminal 300 . When the stop terminal 300 receives an activation signal from the terminal 100 for the weak in traffic, the stop terminal 300 may switch from an inactive state (idle state) to an active state (active state).

A person with disabilities may input a stop guide command to the terminal 100 for the handicapped in transportation. When the traffic-disabled person terminal 100 receives a stop guide command from the traffic-poor person, it may transmit a stop guide command signal to the stop terminal 300 . The stop terminal 300 receiving the stop guide command signal may output stop information. As an embodiment, when a person with reduced traffic who arrives at the stop in front of the AA building inputs a stop guide command to the terminal 100 for the weak in traffic, the terminal 100 for the weak in traffic provides a stop guide command to the stop terminal 300 at the stop in front of the building AA. signal can be transmitted. In addition, the stop terminal 300 may output a voice such as “a stop in front of the AA building.”

Also, when the stop terminal 300 is switched to the active state, the stop terminal 300 may communicate with the bus terminal 200 . The bus terminal 200 is a terminal installed inside the bus and can communicate with the activated stop terminal 300 . When the bus 1 enters the bus stop, the bus terminal 200 may transmit bus information to the activated stop terminal 300 . For example, the bus information may include bus number information. When the stop terminal 300 receives bus information from the bus terminal 200 , the stop terminal 300 may output bus entry guide information. As an embodiment, when the stop terminal 300 receives the bus information of the 120 bus, the stop terminal 300 may output a voice such as “Bus 120 is entering.” When the bus 1 stops at the stop and the door is opened, the bus terminal 200 located in the bus may output its own bus information. As an embodiment, when the 120 bus stops at the bus stop and the door is opened, the bus terminal 200 of the 120 bus may output a voice such as “This is the 120 bus.” Accordingly, the traffic-disabled person listens to the bus entry guide information output from the stop terminal 300 and the bus information output from the bus terminal 200 of the bus stopped at the stop, and determines whether the bus 1 he or she will board enters the bus 1 or not. You can check the stop position.

On the other hand, there may be a situation in which the traffic weak person re-checks the stop information and the bus information. A person with disabilities may input an information re-output command to the terminal 100 for the weak in transportation. Upon receiving the information re-output command, the transportation-disabled person terminal 100 may transmit an information re-output command signal to the bus terminal 200 and the bus stop terminal 300 . The bus terminal 200 that has received the information re-output command signal may re-output bus information, and the stop terminal 300 that has received the information re-output command may re-output the stop information.

So far, the bus guidance system has been described. Hereinafter, the configuration of the handicapped terminal 100, the bus terminal 200, and the bus stop terminal 300 included in the bus guide system will be described.

2 is a block diagram of a terminal for the weak in transportation according to an embodiment of the present disclosure. Referring to FIG. 2 , the transportation-disabled person terminal 100 may include an input unit 110 , a control unit 120 , and a communication unit 130 .

The input unit 110 may receive a variety of commands from the vulnerable in traffic. For example, the input unit 110 may be implemented in the form of a button, a touchpad, or the like. When the input unit 110 is implemented as a button, the input unit 110 may include a plurality of buttons. Each button of the input unit 110 may receive different commands, and one button may receive a plurality of commands. For example, when a person with disabilities selects the first button of the input unit 110 , the terminal 100 for the person with reduced mobility may recognize it as an information request command. Alternatively, when a person with disabilities selects the first button of the input unit 110 , the terminal 100 for the weak in traffic may recognize the terminal as a stop terminal activation command. After the stop terminal is activated, when the traffic weak person selects the first button again, the traffic vulnerable terminal 100 may recognize it as a stop guide command.

On the other hand, when the input unit 110 is implemented as a touch pad, a vibration function may be included so that a person with reduced traffic can recognize whether or not a touch has been made. For example, when the touch pad and the vibration motor are connected and the touch pad recognizes a touch, the vibration motor may perform a vibration function. If it is, the touch pad of the input unit 110 may recognize the command of the traffic weak according to the touch gesture. For example, when the touch pad of the input unit 110 receives a touch gesture that is continuously pressed for a certain period of time, the traffic-impaired terminal 100 recognizes it as an information request signal transmission command, and the touch pad of the input unit 110 sweeps upward. When a touch gesture is input, the terminal 100 for the weak in traffic recognizes it as a stop terminal activation command, and when a touch gesture for sweeping down is input, the terminal 100 for the weak in traffic can recognize it as a stop guide command.

The above-described number of buttons, touch gestures, and commands corresponding to inputs of the input unit 110 are an example, and the number of buttons, touch gestures, and commands corresponding to inputs of the input unit 110 may be set in various ways.

The communication unit 130 may communicate with the bus terminal and the bus stop terminal. The communication unit 130 may transmit an information request signal to the bus stop terminal. Alternatively, the communication unit 130 may transmit an activation signal to the stop terminal upon receiving an activation command of the stop terminal. When receiving a stop guide command, the communication unit 130 may transmit a stop guide command signal to the stop terminal. In addition, the communication unit 130 may transmit an information re-output command signal to the bus terminal and the bus stop terminal upon receiving the information re-output command.

For example, the communication unit 130 may include a short-range communication module and a mobile communication module. For example, the short-distance communication module may communicate with an external device in a short distance using a communication method such as Bluetooth, Wi-Fi, RFID, infrared communication, Zigbee, or NFC. In addition, the mobile communication module may communicate with a server or other terminal device according to a mobile communication method such as CDMA, GSM, WCDMA, LTE, LTE-A, 5G, or the like. Meanwhile, the terminal device 100 may transmit/receive data to and from a server or other terminal device according to wireless Internet technologies such as Wi-Fi, wireless LAN, WiBro, LTE, LTE-A, and 5G, and wireless Internet communication is performed through a mobile communication network. In view of the fact that it is made, a communication module for wireless Internet communication can also be viewed as a type of mobile communication module.

The controller 120 may control the input unit 110 and the communication unit 130 . That is, it is possible to determine the command input from the input unit 110 and control the communication unit 130 to transmit a signal corresponding to the determined command to an external device.

3 is a block diagram of a bus terminal according to an embodiment of the present disclosure. Referring to FIG. 3 , the bus terminal 200 may include a communication unit 210 , a control unit 220 , and an output unit 230 .

The communication unit 210 may receive activation state information from the stop terminal and transmit bus information to the stop terminal. In addition, the communication unit 210 may receive the information re-output command signal from the transportation-disabled terminal.

The output unit 230 may output bus information when the door of the bus is opened. In addition, bus information may be output in response to the information re-output command signal. For example, the output unit 230 may be implemented as a speaker.

The controller 220 may control the communication unit 210 and the output unit 230 . That is, it is possible to determine the signal received by the communication unit 210 and control the communication unit 210 to transmit a signal corresponding to the determined signal to an external device or control the output unit 230 to output a voice.

On the other hand, the stop terminal may also include a configuration similar to that of the bus terminal 200 . That is, the bus stop terminal may also include a communication unit, a control unit, and an output unit.

The communication unit of the stop terminal may receive an activation command signal, a stop guide command signal, an information re-output command signal, and the like from the terminal for the weak in traffic. In addition, the communication unit of the bus stop terminal may transmit activation state information to the bus terminal and receive bus information from the bus terminal.

The output unit of the stop terminal may output bus guide information or stop information in response to the received signal. For example, the output unit of the bus stop terminal may also be implemented as a speaker.

The control unit of the stop terminal may control the communication unit and the output unit of the stop terminal. That is, the control unit of the bus stop terminal may determine the signal received from the communication unit, control the communication unit to transmit a signal corresponding to the determined signal to an external device, or control the output unit to output a voice. In addition, when receiving an activation signal from the terminal for the weak in traffic, the control unit of the stop terminal may convert the stop terminal in the standby state to the active state.

4 is a flowchart of a method for controlling a bus guidance system for providing information to the traffic-disabled person according to an embodiment of the present disclosure. The method of controlling the bus guidance system of FIG. 4 is a flowchart of an embodiment in which a person with reduced traffic arrives at a stop and gets on a bus.

The handicapped terminal transmits an information request signal to the bus stop terminal (S410). On the other hand, the transportation-disabled terminal may transmit an activation signal of the bus stop terminal before or together with the information request signal. For example, the bus stop terminal may be normally in an inactive state (standby state). Upon receiving a command for activation of the stop terminal from the traffic vulnerable terminal, the terminal may transmit an activation signal of the stop terminal to the stop terminal located at the bus stop. Upon receiving the activation signal, the bus stop terminal may switch from an inactive state to an active state. On the other hand, when receiving a stop guide command from the traffic vulnerable terminal, the terminal may transmit a stop guide command signal to the stop terminal. In addition, the stop terminal receiving the stop guide command signal may output information on the stop.

The bus stop terminal communicates with the bus terminal in the bus. That is, the bus stop terminal that has received the information request signal transmits the information request signal to the bus terminal (S420). And, when the bus enters within a preset distance from the stop terminal, the bus terminal receiving the information request signal transmits bus information to the stop terminal (S430). The bus stop terminal that has received the bus information outputs bus entry guide information (S440). When the bus stops at the bus stop and the door of the bus is opened, the bus terminal outputs bus information (S450). On the other hand, the transportation-disabled terminal may receive an information re-output command from the transportation-disabled person. The transportation-disabled terminal receiving the information re-output command may transmit an information re-output command signal to the bus terminal and the bus stop terminal. The bus terminal receiving the information re-output command signal may re-output bus information, and the bus terminal receiving the information re-output command signal may re-output information on the bus stop.

Up to now, an embodiment of the bus guidance system that operates until a person with reduced mobility gets on the bus has been described. Hereinafter, an embodiment of a bus guidance system that operates when a person with reduced mobility gets off the bus will be described.

5 is a view for explaining a bus guidance system related to getting off the traffic weak person according to an embodiment of the present disclosure.

Referring to Figure 5 (a), the bus terminal 200 is shown a process of adding the identification information of the traffic-weak terminal to the alighting bell operation list to the getting off bell operation list.

The handicapped terminal 100 may broadcast a signal. The signal broadcast by the transportation-disabled terminal 100 may be a short-range wireless communication connection signal for communicating with the bus terminal 200 . The transportation-disabled terminal 100 may broadcast a signal according to a selection command of the transportation-disabled person, and may periodically broadcast the signal after performing communication with the bus stop terminal 300 .

When the bus door is opened, the bus terminal 200 may receive opening/closing information of the bus door. The bus terminal 200 may receive information on opening/closing a bus door based on a wired/wireless communication method from an electronic system of a bus that detects whether the bus door is opened or closed. When the bus terminal 200 receives the bus door opening/closing information indicating that the bus door has been opened, it may scan a signal of the transportation vulnerable terminal 100 located within a certain range. When the bus terminal 200 scans the signal 100 of the terminal for the weak in traffic, it receives the identification information from the terminal 100 for the weak in traffic that the signal is scanned, and removes the received identification information of the terminal 100 for the weak in traffic to get off the bell operation list can be added to For example, the identification information of the terminal 100 for the weak in traffic may include MAC address information of the terminal 100 for the weak in traffic, unique information of the traffic weak, or unique information of the terminal 100 for the weak in traffic.

Referring to Figure 5 (b), the bus terminal 200 is shown a process of deleting the identification information of the terminal for the weak in traffic from the get-off ring operation list. The bus terminal 200 may repeatedly scan the signal of the traffic-impaired terminal 100 a plurality of times at a preset time interval for a preset number of times, and receive identification information from the traffic-impaired terminal 100 for which the signal is scanned. As an embodiment, the bus terminal 200 may scan the signal of the terminal 100 for the weak in traffic every 30 seconds for 5 minutes after the bus door is opened. Similarly, the transportation-disabled terminal 100 may also broadcast a signal periodically for 5 minutes after receiving the bus opening/closing information. If a person with a disability in transportation having a first terminal is riding a bus, and a person with a weakness in transportation having a second terminal is at a stop, the bus terminal 200 receives the signals from the first and second terminals Since they can all be scanned, identification information of the first and second handicapped terminals can be added to the alighting bell operation list. After the bus departs, when the bus terminal 200 scans the signal of the terminal for the vulnerable in traffic, only the signal of the first terminal for the weak in traffic is scanned, and the signal of the terminal for the weak in traffic is not scanned at the stop. have. The bus terminal 200 may remove the identification information of the second terminal for the weak in traffic for which a signal is not scanned from the alighting bell operation list. That is, the bus terminal 200 may delete identification information for which a signal is scanned for less than a preset number of times among identification information included in the alighting bell operation list from the alighting bell operation list.

When the bus arrives near the stop where the traffic-disabled person is scheduled to get off, the traffic-disabled person may input a get-off command to the transportation-disabled person terminal 100 . When the transportation-disabled person terminal 100 receives a get-off command, the transportation-disabled person terminal 100 may transmit identification information to the bus terminal 200 . When the bus terminal 200 receives the identification information from the transportation vulnerable terminal 100, the bus terminal 200 may compare it with the identification information included in the alighting bell operation list. When the received identification information matches the identification information included in the getting off bell operation list, the bus terminal 200 may output a get off bell notification.

As described above, the transportation-disabled person terminal 100 may include an input unit, a control unit, and a communication unit. The input unit of the terminal for the disadvantaged in transportation may receive an alighting command from the disabled in traffic. The communication unit of the terminal for the weak in traffic may periodically broadcast a signal and transmit identification information to the bus terminal according to a get-off command inputted from the weak in traffic. The control unit of the transportation-disabled person terminal may control the input unit and the communication unit.

In addition, the bus terminal 200 may include a communication unit, a control unit, and an output unit. The communication unit of the bus terminal may perform communication with the transportation vulnerable terminal. In addition, the communication unit may receive a get-off request signal from the transportation vulnerable terminal. In addition, the control unit of the bus terminal may compare the received identification information of the terminal for the weak in traffic with the identification information included in the alighting bell operation list. The control unit may control the output unit to output a notification of getting off when the received identification information of the terminal for the vulnerable in traffic matches the identification information included in the getting off bell operation list.

6 is a view for explaining an embodiment of managing a get-off bell operation list.

Referring to FIG. 6 , an embodiment in which the identification information of the traffic-weakened terminal is MAC address information is illustrated. The bus terminal may receive a signal including the MAC address a plurality of times, and may determine the signal including the same MAC address each time as a signal of the terminal of a person with reduced mobility on board.

According to FIG. 6 , the bus terminal may first receive signals from a plurality of terminals for the weak in traffic. For example, the MAC addresses included in the first received signal of the mobile terminal are (11:22:33:44:55:66), (21:32:45:65:72:ab), (ab: 41:54:32:34:73). The MAC addresses included in the second received signal from the handicapped terminal after a certain time are (11:22:33:44:55:66), (34:71:54:44:ba:73), (ab: 41), respectively. :54:32:34:73), (21:43:56:91:84:44). The MAC addresses included in the signal from the terminal for the third time received after a certain period of time are (11:22:33:44:55:66), (21:32:45:65:72:ab), (31:45), respectively. :82:98:33:78), (bc:11:48:cd:47:ff). The MAC address commonly included every time from 1st to 3rd is (11:22:33:44:55:66). Accordingly, the bus terminal may determine the terminal for the weak in traffic that has transmitted the signal including the MAC address (11:22:33:44:55:66) as the terminal of the weak in transport riding the bus. On the other hand, the bus terminal may delete the remaining MAC addresses from the get-off ring operation list except for the MAC addresses commonly included in each scan of the traffic-disabled terminal. Similar to the above, even when the identification information of the terminal for the weak in traffic is unique information of the terminal 100 or the like, the bus guidance system may operate in the same manner as in the above-described embodiment.

7 is a flowchart of a bus guidance system control method for operating a get-off bell according to an embodiment of the present disclosure.

The handicapped terminal may broadcast a signal (S710).

When the bus door is opened, the bus terminal may receive opening/closing information of the bus door (S720).

The bus terminal that has received the bus door opening/closing information may scan a signal of the terminal for the weak in traffic located within a preset range (S730).

The bus terminal may receive the identification information of the terminal for the weak in traffic for which the signal is scanned and add it to the alighting ring operation list (S740). On the other hand, the bus terminal may scan the signal of the terminal for the weak in traffic a plurality of times at regular time intervals for a certain number of times. In addition, the bus terminal may delete identification information added to the get-off ring operation list according to a certain condition. For example, the bus terminal may delete identification information of the terminal for the weak in traffic in which a signal is scanned less than a predetermined number of times from among the identification information included in the alighting bell operation list, from the alighting bell operation list. Alternatively, the bus terminal may scan the signal of at least one terminal for the weak in traffic at each number of times of scanning the signal of the terminal for the weak in traffic. In addition, the bus terminal may delete the remaining identification information except for the identification information commonly included in all the times among the identification information of at least one terminal for the weak in transportation for which the signal is scanned for each number of times.

The bus terminal may receive a get-off request signal including identification information from the terminal for the weak in traffic (S750). When the identification information included in the received getting off request signal is included in the getting off bell operation list, the bus terminal may output a get off bell notification (S760).

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications may be made by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
