Description

Technical Field

[0001] This invention relates to a walkie-talkie device and its communication method, and more specifically, to a wireless walkie-talkie device for motorcycles and its communication method. Background Technology

[0002] Motorcycle riders often travel in groups, and the noise from motorcycle engines makes it difficult for riders to communicate with each other.

[0003] Riders communicate with each other while riding using talkback devices mounted on their motorcycle helmets.

[0004] Conventional walkie-talkies are primarily designed for communication via Bluetooth. However, because Bluetooth communication is mainly configured for point-to-point communication, there are some issues when multiple cyclists communicate with each other.

[0005] To enable multiple cyclists to communicate with each other via Bluetooth, their walkie-talkies can be configured to be connected in a daisy-chain configuration. Alternatively, to allow multiple cyclists to communicate with each other, their walkie-talkies can be configured to be connected in a mesh configuration.

[0006] However, the following problems exist: In group rides, as the distance between riders increases, the Bluetooth communication connection between riders may drop; furthermore, if the Bluetooth communication of any one intercom device drops, all Bluetooth communication connections between riders may also drop. Moreover, the Bluetooth pairing process between intercom devices is very complex, difficult, and time-consuming.

[0007] Therefore, when four or more cyclists form a group, they cannot use walkie-talkies, but instead use group calls, instant messaging group calls, or products that support mesh communication over mobile networks.

[0008] However, the problem is that it is not easy to create a group call network by adding dozens of phone numbers one by one on a mobile communication network, and in the case of instant messaging group calls, the instant messaging group will be disconnected immediately when a mobile communication call comes in.

[0009] In conclusion, when four or more cyclists ride together as a group, conventional Bluetooth walkie-talkies are likely to become useless.

[0024] Here, when pairing the motorcycle walkie-talkie with the plurality of other motorcycle walkie-talkies and establishing the Bluetooth connection, the Bluetooth connection can be established by daisy-chaining the motorcycle walkie-talkies with the plurality of other motorcycle walkie-talkies.

[0025] Furthermore, when a Bluetooth connection is established by daisy-chaining with the other motorcycle walkie-talkies, the motorcycle walkie-talkies can conduct group calls with the other motorcycle walkie-talkies via the Bluetooth connection.

It will also be understood that terms—such as those defined in common dictionaries—should be interpreted as consistent with their meaning in the relevant field context and should not be interpreted in an idealized or overly formal manner unless explicitly defined herein.

[0069] In the following, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0070] Figure 1 This is a schematic diagram of a wireless intercom system for motorcycles according to an embodiment of the present invention.

[0071] Reference Figure 1 Motorcycle intercom systems can be configured to enable group calls between motorcycle intercom devices in various ways.

[0072] In a first embodiment, the motorcycle radio system can be configured to allow motorcycle radio devices to conduct group calls via Bluetooth communication. Here, Bluetooth communication enables motorcycle radio devices to be connected in a daisy-chain configuration and conduct group calls.

[0073] In the second embodiment, the motorcycle intercom system may include a mobile Wi-Fi router 100 and at least one mobile Wi-Fi repeater 200 connected to the mobile Wi-Fi router 100. The system can be configured such that multiple motorcycle intercom devices 300 constituting a motorcycle group are connected to the mobile Wi-Fi router 100 or the mobile Wi-Fi repeater 200 to form a Wi-Fi subgroup capable of communication with each other. This Wi-Fi communication enables group calls between the motorcycle intercom devices. Here, a Dynamic Host Configuration Protocol (DHCP) server can be configured to assign an IP (Internet Protocol) address to each motorcycle intercom device to enable group calls between them.

[0074] When 20 to 30 riders ride in a group, the motorcycles sometimes form a line of about 100 meters. In this case, the line is quite long, and the Bluetooth communication connection is frequently dropped due to changes in the position of the motorcycles. Therefore, by configuring the mobile Wi-Fi router 100 and the mobile Wi-Fi repeater 200 as hosts, group calls can be made between the motorcycle wireless intercom devices 300, thereby enabling stable communication.

[0075] Even if the motorcycle's location changes, it can be reconnected to the mobile Wi-Fi router 100 or mobile Wi-Fi repeater 200 with the strongest Wi-Fi signal, thus preventing communication interruptions due to the motorcycle's location change.

[0076] Specifically, when the motorcycle wireless intercom device 300 is far from a specific Wi-Fi signal range, the motorcycle wireless intercom device 300 that is outside the Wi-Fi signal radius can pair with the nearest other motorcycle wireless intercom device 300 via Bluetooth to establish a Bluetooth connection, and can switch between Bluetooth and Wi-Fi connections to maintain the two motorcycle wireless intercom devices 300 in a group call.

[0077] In other words, when the motorcycle wireless intercom device 300 is far away from the Wi-Fi group, the group call can be stably maintained through Bluetooth communication.

[0078] Specifically, the motorcycle radio intercom 300 and the mobile Wi-Fi repeater 200 can be configured to register the intercom ID and Wi-Fi repeater ID in the mobile Wi-Fi router 100 via near field communication (NFC) tags. Here, the NFC tag enables the motorcycle radio intercom 300 to register the intercom ID with each other.

[0079] Wi-Fi connection can only be established by pre-registering the walkie-talkie ID and Wi-Fi repeater ID, thus preventing other terminals or walkie-talkies from connecting to the corresponding motorcycle group via Wi-Fi.

[0080] In a third embodiment, the motorcycle wireless intercom system can be configured to enable group calls between motorcycle wireless intercom devices via a mobile communication network. In this case, a dedicated group call server can be configured to establish call sessions between users' terminals (i.e., smartphones), thereby enabling Voice over Internet Protocol (VoIP) group calls. In this VoIP group call, communication will not be interrupted even if the motorcycles (i.e., users) are far apart. Each user terminal can communicate via Bluetooth with the earpiece microphone of the motorcycle wireless intercom device mounted on the helmet.

[0081] When a specific user is excluded from a Wi-Fi subgroup, preventing Wi-Fi communication, group calls can be maintained via Bluetooth communication as described above, or via VoIP communication. For VoIP communication, the DHCP server can be configured to pre-assign IP addresses to each pre-registered user terminal.

[0082] Figure 2a and Figure 2b This is a block diagram of a wireless intercom device for motorcycles according to an embodiment of the present invention.

[0083] Reference Figure 2a and Figure 2b According to an embodiment of the present invention, a motorcycle wireless intercom device may include a mobile Wi-Fi router 100, a mobile Wi-Fi repeater 200, and a motorcycle wireless intercom device 300.

The router-side Wi-Fi connection enable / block module 108 can match the IP address assigned by the DHCP server 10 with the intercom ID or Wi-Fi repeater ID to obtain matching data, and can use the obtained matching data to enable or block the Wi-Fi connection.

[0097] The router-side Wi-Fi node sharing module 109 can be configured to share the Wi-Fi router ID stored in the Wi-Fi router ID storage module 101 and the walkie-talkie ID stored in the router-side walkie-talkie ID storage module 104 with the mobile Wi-Fi repeater 200. In this case, matching data that matches the IP address assigned by the DHCP server 10 will also be shared.

[0098] The mobile Wi-Fi repeater 200 can be configured to relay Wi-Fi communications performed by the mobile Wi-Fi router 100.

[0099] Here, the mobile Wi-Fi repeater 200 can be carried by the user or installed on the user's motorcycle.

[0100] The mobile Wi-Fi repeater 200 may include a Wi-Fi repeater ID storage module 201, a repeater-side NFC tag 202, a repeater-side Wi-Fi communication module 203, a repeater-side Wi-Fi node storage module 204, and a repeater-side Wi-Fi connection enable / block module 205.

[0101] Its detailed configuration will be described below.

[0102] Wi-Fi repeater ID storage module 201 can be configured to pre-store Wi-Fi repeater IDs.

[0103] The repeater-side NFC tag 202 can be configured to store the Wi-Fi repeater ID corresponding to the Wi-Fi repeater ID pre-stored in the Wi-Fi repeater ID storage module 201, and allow the stored Wi-Fi repeater ID to be transmitted to the NFC module 102 of the mobile Wi-Fi router 100 via NFC communication.

[0104] The repeater-side Wi-Fi communication module 203 can be configured to communicate with the mobile Wi-Fi router 100 and the motorcycle wireless intercom device 300 via Wi-Fi, and pre-receives the Wi-Fi router ID and intercom ID shared with the router-side Wi-Fi node sharing module 109.

[0105] The repeater-side Wi-Fi node storage module 204 can be configured to store the Wi-Fi router ID and walkie-talkie ID that are pre-received by the repeater-side Wi-Fi communication module 203.

[0106] The repeater-side Wi-Fi connection enable / block module 205 can be configured to enable or block the Wi-Fi connection between the mobile Wi-Fi repeater 200 and the motorcycle wireless intercom device 300 by referring to the Wi-Fi router ID and intercom ID stored in the repeater-side Wi-Fi node storage module 204, via the repeater-side Wi-Fi communication module 203. Here, the repeater-side Wi-Fi connection enable / block module 205 can enable or block the Wi-Fi connection by referring to the Wi-Fi router ID, intercom ID, and matching data matching each IP address.

[0107] The motorcycle wireless intercom device 300 can be detached from the motorcycle helmet and connected to the mobile Wi-Fi router 100 or the mobile Wi-Fi repeater 200, thereby enabling group calls with other motorcycle wireless intercom devices 300 connected to the mobile Wi-Fi router 100 or the mobile Wi-Fi repeater 200 via Wi-Fi communication.

[0108] The motorcycle wireless intercom device 300 may include an intercom ID storage module 301, an intercom-side NFC tag 302, an intercom-side Wi-Fi communication module 303, an intercom-side Wi-Fi node storage module 304, a group call module 305, an earpiece microphone 306, a Wi-Fi signal strength measurement module 307, a Wi-Fi connection control module 308, an automatic pairing control module 309, a Bluetooth module 310, a one-to-one call module 311, a call selection switch module 312, and an automatic communication protocol conversion module 313.

[0109] Its detailed configuration will be described below.

[0110] The walkie-talkie ID storage module 301 can be configured to pre-store walkie-talkie IDs.

[0111] The walkie-talkie side NFC tag 302 can be configured to store the walkie-talkie ID corresponding to the walkie-talkie ID pre-stored in the walkie-talkie ID storage module 301.

[0112] Additionally, the walkie-talkie-side NFC tag 302 can be configured to allow the walkie-talkie ID pre-stored in the walkie-talkie ID storage module 301 to be transmitted via NFC communication to the NFC module 102 of the mobile Wi-Fi router 100.

[0113] The walkie-talkie-side Wi-Fi communication module 303 can be configured to communicate with the mobile Wi-Fi router 100 and the mobile Wi-Fi repeater 200 via Wi-Fi.

[0114] Additionally, the walkie-talkie-side Wi-Fi communication module 303 can be configured to receive in advance the Wi-Fi router ID and Wi-Fi repeater ID shared with the router-side Wi-Fi node sharing module 109.

[0115] The walkie-talkie-side Wi-Fi node storage module 304 can be configured to store the Wi-Fi router ID and Wi-Fi repeater ID that are pre-received by the walkie-talkie-side Wi-Fi communication module 303.

[0116] The group call module 305 can be configured to conduct group calls with another motorcycle wireless intercom device 300 via Wi-Fi communication through the walkie-talkie-side Wi-Fi communication module 304.

[0117] The earpiece microphone 306 can be configured to receive user voice during group calls conducted by the group call module 305, and output the voice of other users in the group call.

[0118] The Wi-Fi signal strength measurement module 307 can be configured to measure in real time the strength of the Wi-Fi signal previously received by the walkie-talkie-side Wi-Fi communication module 303.

[0119] The Wi-Fi connection control module 308 can be configured to control the walkie-talkie-side Wi-Fi communication module 303 to connect via Wi-Fi to a mobile Wi-Fi router 100 or a mobile Wi-Fi repeater 200 that has the highest Wi-Fi signal strength measured in real time by the Wi-Fi signal strength measurement module 307, by referring to the walkie-talkie-side Wi-Fi node storage module 304.

[0120] The automatic pairing control module 309 can automatically pair with another pre-set motorcycle wireless intercom device 300 via Bluetooth when the Wi-Fi signal strength of the mobile Wi-Fi router 100 or mobile Wi-Fi repeater 200, as measured in real time by the Wi-Fi signal strength measurement module 307, is less than or equal to a preset reference value. Therefore, even if a specific motorcycle's dedicated intercom device 100 is excluded from the motorcycle group and cannot conduct Wi-Fi communication, group communication can still be maintained.

[0121] The Bluetooth module 310 can be configured to communicate with another pre-paired motorcycle radio 300 via Bluetooth. When the Bluetooth connection is lost during riding, the Bluetooth module 310 can automatically re-pair with the other motorcycle radio 300 that currently has the strongest signal and resume Bluetooth communication.

[0122] Meanwhile, the Bluetooth signal strength monitoring module (not shown in the figure) can be configured to monitor in real time whether the Bluetooth signal strength is lower than a specific reference value. When the real-time monitoring result is that the Bluetooth signal strength is lower than the specific reference value, the corresponding user is notified in real time through the ear-worn microphone 306 that the Bluetooth signal strength is low.

[0123] In addition, the GPS distance monitoring module (not shown in the figure) can be configured to monitor the GPS location information of the user terminal 400 of the corresponding user connected to each motorcycle wireless intercom 300, so as to calculate the distance between users in real time.

[0124] In addition, the Bluetooth module 310 can be configured to automatically pair with another pre-set motorcycle wireless intercom device 300 under the control of the automatic pairing control module 309 for Bluetooth communication.

[0125] The one-to-one calling module 311 can be configured to make one-to-one calls with another pre-paired motorcycle wireless intercom device 300 via Bluetooth communication performed by the Bluetooth module 310.

[0126] The call selection switching module 312 can be configured to switch between group calls of the group call module 305 and one-to-one calls of the one-to-one call module 311.

[0127] Users can make one-on-one calls with specific users whose devices have been pre-paired via Bluetooth, and also make group calls.

[0128] The automatic communication protocol conversion module 313 can be configured to automatically and in real-time convert the communication protocols between the following two devices: one is Bluetooth communication between the Bluetooth module 310 and another motorcycle wireless intercom device 300 that has been automatically paired under the control of the automatic pairing control module 309; the other is Wi-Fi communication between the walkie-talkie-side Wi-Fi communication module 303 and another motorcycle wireless intercom device 300 that has been automatically paired under the control of the automatic pairing control module 309. Since both Bluetooth and Wi-Fi communication are essentially based on data packets, by converting the Bluetooth and Wi-Fi protocols to data packets, the call can be kept within a single group call.

[0129] Meanwhile, the router-side connected user ID monitoring module (not shown in the figure) of the mobile Wi-Fi router 100 can be configured to monitor the currently connected motorcycle wireless intercom device 300 in real time, generate a router-side connected user list in real time, and store the generated router-side connected user list in the router-side connected user list storage module (not shown in the figure).

[0130] In addition, the repeater-side connected user ID monitoring module (not shown in the figure) of the mobile Wi-Fi repeater 200 can be configured to monitor the currently connected motorcycle wireless intercom device 300 in real time, generate a repeater-side connected user list in real time, and store the generated repeater-side connected user list in the repeater-side connected user list storage module (not shown in the figure).

[0131] Meanwhile, the repeater-side connected user list sharing module (not shown in the figure) of the mobile Wi-Fi repeater 200 can be configured to share the repeater-side connected user list stored in the repeater-side connected user list storage module (not shown in the figure) with the mobile Wi-Fi router 100 in real time.

[0132] The excluded user monitoring module (not shown in the figure) of the mobile Wi-Fi router 100 can be configured to collect the router-side connected user list stored in the router-side connected user list storage module (not shown in the figure) and the repeater-side connected user list shared in real time with the repeater-side connected user list sharing module (not shown in the figure), generate a group call list in real time, compare the real-time generated group call list with the walkie-talkie ID stored in the router-side walkie-talkie ID storage module, and identify excluded users of the Wi-Fi group in real time.

[0133] Furthermore, the excluded user notification module (not shown in the figure) of the mobile Wi-Fi router 100 can be configured to output excluded users identified in real time by the excluded user monitoring module (not shown in the figure) to the group call channel in the form of voice notifications. Users can easily identify excluded users from among the many users in the group while cycling. In other words, users who have had accidents, fallen behind, or gone astray can be easily identified.

[0134] On the other hand, the mobile Wi-Fi router 100 or mobile Wi-Fi repeater 200 can be implemented as an application on each user's smartphone. The aforementioned mobile Wi-Fi router 100 or mobile Wi-Fi repeater 200 can be implemented using the built-in Wi-Fi module (not shown in the figure) of each user terminal 400 (i.e., the user's smartphone). Wi-Fi relaying can be performed using the hotspot function of the user terminal 400. The user terminal 400 can be divided into a hotspot host terminal, a hotspot relay terminal, and a hotspot terminal. The hotspot host terminal can be configured to correctly implement the function of the mobile Wi-Fi router 100, the hotspot relay terminal can be configured to correctly implement the function of the mobile Wi-Fi repeater 200, and the hotspot terminal can be configured to correctly implement the function of the motorcycle wireless intercom device 300. All user terminals 300 can function as a hotspot host terminal, a hotspot relay terminal, and a hotspot terminal respectively, according to the settings on the application. In this paper, the hotspot host terminal can be configured to collect GPS location information of each hotspot relay terminal and each hotspot terminal in real time, and can automatically grant hotspot relay terminal permissions to specific hotspot terminals in real time using the collected GPS location information. In this way, even if the positions of each motorcycle change frequently and there are lagging motorcycles, the group call status can be maintained stably through signal strength.

[0135] Meanwhile, each user terminal 400 can be pre-installed with a dedicated group call application. Under the control of the dedicated group call server 400, user terminals 400 can conduct VoIP voice calls. The dedicated group call server 400 can be configured to use the IDs and IP addresses of the router-side Wi-Fi nodes shared with the router-side Wi-Fi node sharing module 109 to set up group call sessions.

[0136] In this scenario, when excluded users exist during Wi-Fi communication, as described above, the connection can be maintained via Bluetooth communication and the group call status can be maintained through communication protocol conversion. Alternatively, the dedicated group call server 400 can maintain the group call status for the respective excluded users. In this case, the automatic communication protocol conversion module 313 can convert VoIP voice call data packets into Wi-Fi communication call data packets, enabling the excluded users to connect to the corresponding group call session.

[0137] On the other hand, the motorcycle-mounted intercom device 300 may include an acceleration sensor (not shown). This acceleration sensor (not shown) may be configured to detect 3D acceleration greater than or equal to a predetermined angular acceleration. 3D acceleration greater than or equal to the predetermined angular acceleration may be, for example, a left or right turn at an intersection at 70 to 80 degrees or greater.

[0138] In this case, the walkie-talkie-side Wi-Fi communication module 303 can transmit in real time the 3D acceleration detected by the accelerometer (not shown) that is greater than or equal to the predetermined angular acceleration to the router-side Wi-Fi communication module 107 or the repeater-side Wi-Fi communication module 203.

[0139] In addition, the router-side Wi-Fi communication module 107 of the mobile Wi-Fi router 100 can receive 3D acceleration in real time from the walkie-talkie-side Wi-Fi communication module 107 or the repeater-side Wi-Fi communication module 203.

[0140] In addition, the excluded user monitoring module (not shown) can compare the 3D acceleration received in real time from the Wi-Fi communication module 107 on the router side within a predetermined time interval, and identify the motorcycle-mounted intercom device 300 whose 3D acceleration exceeds the predetermined range as an excluded user based on the comparison result.

[0141] The mobile Wi-Fi router 100 may also include a GPS module (not shown in the figure) and an excluded user information transmission module (not shown in the figure).

[0142] In this paper, the GPS module (not shown) can be configured to generate real-time router GPS location information.

[0143] The excluded user information transmission module (not shown) can be configured to transmit real-time router GPS location information generated by the GPS module (not shown) and excluded users identified by the excluded user monitoring module (not shown) to the group call dedicated server 400 in real time.

[0144] In addition, the group call dedicated server 400 can receive real-time router GPS location information and excluded users from the excluded user information transmission module (not shown) of the mobile Wi-Fi router 100, and request the real-time GPS location information of the excluded users from the user terminal 500 of the received excluded users and receive the real-time GPS location information of the received excluded users.

[0145] In addition, the user terminal 500 can be configured to generate real-time route guidance information for heading to the pre-received real-time router GPS location information based on the received real-time GPS location information of the excluded user, and provide the generated real-time route guidance information to the user terminal 500 of the excluded user in real time.

[0146] User terminal 500 can be controlled to receive real-time route guidance information from group call dedicated server 400 and output voice through motorcycle-mounted intercom device 300 of excluded users, who can easily join the group through voice route guidance.

[0147] Figure 3 This is a flowchart of a communication method for a motorcycle wireless intercom device according to an embodiment of the present invention.

[0148] Reference Figure 3 The motorcycle wireless intercom device 300 connects via Bluetooth by pairing with another motorcycle wireless intercom device 300 (S101).

[0149] In this configuration, the motorcycle radio 300 can be configured to perform Bluetooth connectivity by daisy-chaining with multiple other motorcycle radios 300.

[0150] Next, the motorcycle wireless intercom 300 connects with another motorcycle wireless intercom 300 via Bluetooth to conduct a voice call (S102).

[0151] In this configuration, the motorcycle walkie-talkie 300 can be configured to conduct group calls with multiple other motorcycle walkie-talkies 300 when a Bluetooth connection is established by daisy-chaining with them.

[0152] Next, when the Bluetooth connection is lost, it automatically pairs with another motorcycle wireless intercom device 300 that has the strongest Bluetooth signal strength among multiple other motorcycle wireless intercom devices 300, thereby establishing a Bluetooth connection in a daisy chain manner (S103).

[0153] Next, the motorcycle walkie-talkie 300 establishes a Bluetooth connection through automatically performed Bluetooth pairing to conduct voice communication with another motorcycle walkie-talkie 300 (S104).

[0154] Although the invention has been described above with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made without departing from the spirit and scope of the invention as described in the appended claims.
