Description

Technical Field

[0001] The present application relates to vehicle communication technology, and more particularly to a vehicle real-time full-duplex digital multi-person intercom transmission method and device. Background Art

[0002] Traveling in groups of motorcycles has become a fashionable and popular leisure activity. When traveling in groups of motorcycles, communication between each other is mainly achieved through mobile phones or intercoms. Unlike the indoor call environment of a car, when driving a motorcycle, it is necessary to use a call device built into the helmet to establish communication with other vehicles. In the prior art, a Bluetooth adapter is usually set on the helmet, and the helmet establishes Bluetooth communication with the mobile phone, or the helmet establishes Bluetooth communication with the car radio, and it is usually a one-to-one or one-to-many transmission mode. When there are two people on a motorcycle, the two people can still communicate in a traditional way. When there are two people on multiple motorcycles, it is often necessary to switch the in-car channel and the out-of-car channel. If there is a sudden call on the mobile phone, it will switch from the car radio to the mobile phone transmission, which makes the communication effect very unsatisfactory when multiple people are networked. During the intercom process, different intercom people can only be distinguished by the tone, and it is not clear how far the intercom person is from oneself. Therefore, it is necessary to provide an intercom transmission method that can achieve clear and orderly communication for a multi-person networking communication scenario with two people riding on multiple motorcycles. Summary of the invention

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] Embodiment 1 Please refer to Figure 1 - Fig.11The first embodiment provides a vehicle real-time full-duplex digital multi-person intercom transmission method, which is applied to multi-person network intercom transmission between multiple two-person motorcycles 100. The method includes the following steps: S10 The helmet communicators 10 and mobile phones 20 of the front and rear users of the motorcycle 100 respectively establish Bluetooth transmission with the onboard radio 30 of the motorcycle 100, and the mobile phone 20 starts satellite positioning.

[0021] The motorcycle 100 is a two-person motorcycle 100, with one user sitting in front and one in the back, and both users are equipped with a helmet communicator 10 and a mobile phone 20, and the motorcycle 100 is equipped with a car radio 30. The traditional practice is that the helmet communicator 10 establishes Bluetooth communication with the mobile phone 20 and the car radio 30 respectively, and the incoming call of the mobile phone 20 is directly connected to the helmet communicator 10. The practice of this embodiment is that the helmet communicator 10 and the mobile phone 20 establish Bluetooth communication with the car radio 30 respectively, and if the mobile phone 20 has an incoming call, it will first be connected to the car radio 30, and then transmitted to the helmet communicator 10 via the car radio 30.

[0022] At the same time, the user's mobile phone 20 can be bound to the vehicle-mounted radio 30 , and the satellite positioning of the mobile phone 20 can be enabled, and the positioning of the mobile phone 20 can be used as the positioning of the vehicle-mounted radio 30 .

[0023] S20, based on the satellite positioning of the mobile phone 20, when multiple motorcycles 100 enter the signal coverage range of each other's vehicle radios 30, the vehicle radios 30 of the multiple motorcycles 100 switch to the preset networking frequency band and construct an independent audio track for the audio stream output by each vehicle radio 30.

[0024] The speed of the motorcycle 100 is relatively fast. When multiple people travel together, they can be one or two kilometers apart in one or two minutes. Currently, satellite positioning is still the most reliable. The signal coverage range of the vehicle radio 30 is usually known. When multiple motorcycles 100 enter the signal coverage range of each other's vehicle radio 30, they can only contact each other through the mobile phone 20. The mobile phone 20 can only contact one-to-one, which is very inconvenient. When multiple motorcycles 100 enter the signal coverage range of each other's radio, the vehicle radio 30 can be switched to a preset networking frequency band.

[0025] Alternatively, before traveling, the user switches the frequency band of the vehicle radio 30 to the networking frequency band in advance, and when multiple motorcycles 100 enter the signal coverage range of each other's vehicle radios 30, they can automatically enter into networking communication.

[0026] In this embodiment, an independent audio track is constructed for the audio stream output by each vehicle radio 30. The audio stream output by the vehicle radio 30 can be the voice of one user on the motorcycle 100, or a mixture of the voices of two users. The independent audio track is used for independent adjustment of subsequent sound intensity. In terms of geographical location, the positions of the two users of the same motorcycle 100 and the position of the vehicle radio 30 can be considered to be roughly the same. The location of the mobile phone 20 is used to represent the position of the vehicle radio 30, and the position of the vehicle radio 30 is used to represent the positions of the two users.

[0027] S30 Multiple vehicle radio stations 30 correspond to multiple audio tracks. When a vehicle radio station 30 receives an audio stream of an audio track input by other vehicle radio stations 30, the distance between the current vehicle radio station 30 and other vehicle radio stations 30 of the audio stream of the input audio track is obtained according to the satellite positioning of the mobile phone 20, and the volume of different audio tracks is adjusted based on the distance.

[0028] Multiple vehicle radio stations 30 correspond to multiple independent audio tracks. The audio stream of each vehicle radio station 30 is output as an independent audio track. When a vehicle radio station 30 receives the audio stream of the audio track input by other vehicle radio stations 30, the audio track is processed first. The multiple audio tracks input by multiple vehicle radio stations 30 can be processed separately. The specific processing method is: according to the satellite positioning of the user's mobile phone 20, the distance between the current vehicle radio station 30 and other vehicle radio stations 30 that input the audio stream of the audio track is obtained, and the sound intensity of different audio tracks is adjusted based on the distance. The closer the audio track input by other vehicle radio stations 30 is to the current vehicle radio station 30, the closer the original sound intensity is. The farther the audio track input by other vehicle radio stations 30 is from the current vehicle radio station 30, the smaller the sound intensity is adjusted, so as to simulate the effect that the voice of a person who is close is louder, and the voice of a person who is far away is quieter. Therefore, the user can judge the distance of other motorcycles 100 from him according to the sound volume.

[0029] Furthermore, when the audio track of each vehicle-mounted radio 30 is output externally, conventional processing such as noise reduction can be performed first to retain only the clear user voice. This part adopts the existing technology and will not be elaborated.

[0030] More preferably, the helmet intercoms 10 of the front and rear users of the motorcycle 100 output audio streams to the vehicle radio 30 of the motorcycle 100, and the vehicle radio 30 mixes the audio streams output by the two helmet intercoms 10 into an independent audio track and then outputs it externally. The helmet intercoms 10 of the front and rear users of the motorcycle 100 receive the audio stream from the vehicle radio 30 from the external audio stream.

[0031] When the audio stream comes from the helmet intercom 10 of another user of the same motorcycle 100, the audio stream maintains the original sound intensity. The other user of the same motorcycle 100 is always the person closest to the user, and maintains the original sound intensity to clearly distinguish from the users of other motorcycles 100.

[0032] When the audio stream comes from other vehicle-mounted radio stations 30 of other motorcycles 100, the volume of the audio stream is adjusted according to the distance between the two motorcycles 100. The farther the distance between the two motorcycles 100, the smaller the volume of the audio stream is adjusted, and the closer the distance between the two motorcycles 100, the larger the volume of the audio stream is adjusted, and the adjustment range of the audio stream is 30% to 95% of the original volume. Within this range, the user can hear the voice of other users clearly without confusing the voice of other vehicle users with the voice of another user in the same vehicle.

[0033] More preferably, when a call comes in from the user's mobile phone 20, the mobile phone 20 outputs an audio stream to the vehicle radio 30, which is then sent to the user's helmet communicator 10 via the vehicle radio 30. The audio stream sent by the user is sent to the vehicle radio 30 via the helmet communicator 10, and then sent to the user's mobile phone 20 via the vehicle radio 30. Thus, the vehicle radio 30 is used as a relay, rather than directly connecting the mobile phone 20 to the helmet communicator 10.

[0034] In the first embodiment, when a call comes in from the user's mobile phone 20, the vehicle radio 30 switches to one-way transmission with other vehicle radios 30, which means that the vehicle radio 30 only receives audio streams from other vehicle radios 30, and does not output audio streams to other vehicle radios 30. The audio streams of other vehicle radios 30 are input to the vehicle radio 30, and the audio intensity of the audio streams is lowered in the vehicle radio 30, and the vehicle radio 30 stops outputting audio streams to other vehicle radios 30.

[0035] Furthermore, the sound intensity of the audio stream from the mobile phone 20 is recorded as K, and the sound intensity of the audio stream from the other vehicle-mounted radio 30 is recorded as H, satisfying the relationship: K>2H.

[0036] The above relationship is satisfied, so that when the user is communicating on the phone 20, he can still hear the voices of other people in the network, but the voices of other people will not be too loud to affect the communication of the phone 20. At the same time, since the vehicle radio 30 and other vehicle radios 30 are one-way transmission, the voice of the phone 20 will not be heard by other people in the network.

[0037] Embodiment 2 See also Figure 1-Figure 7 The difference between the second embodiment and the first embodiment is that the vehicle radio 30 establishes the first audio track 41 based on the audio stream received from the mobile phone 20, and the vehicle radio 30 establishes the second audio track 42 based on the audio stream received from other vehicle radios 30.

[0038] A further difference between the second embodiment and the first embodiment is that when a call comes in from the user's mobile phone 20 , the vehicle radio 30 maintains two-way transmission with other vehicle radios 30 instead of switching to one-way transmission.

[0039] Specifically, the audio stream in the first audio track 41 is bidirectionally transmitted between the vehicle radio 30 and the helmet intercom 10, the audio stream output by the helmet intercom 10 is incorporated into the first audio track 41, and the audio stream in the first audio track 41 is also output to the helmet intercom 10. The audio stream in the second audio track 42 is unidirectionally transmitted between the vehicle radio 30 and the helmet intercom 10, the audio stream in the second audio track 42 is output to the helmet intercom 10 after reducing the sound intensity, but the audio stream output by the helmet intercom 10 is not incorporated into the second audio track 42.

[0040] The second audio track 42 is bidirectionally transmitted with other vehicle radio stations 30. The audio stream in the second audio track 42 is output to other vehicle radio stations 30. The audio stream input by other vehicle radio stations 30 is also merged into the second audio track 42. Before being merged into the second audio track 42, the audio intensity is adjusted based on the distance between the vehicle radio station 30 and other vehicle radio stations 30. Therefore, there is no need to frequently switch the communication mode between the vehicle radio station 30 and other vehicle radio stations 30, ensuring the stability of communication transmission. Only the internal communication mode is switched between the vehicle radio station 30 and the helmet intercom 10 and the mobile phone 20, which can not only meet the needs of the user for mobile phone 20 calls, but also will not exit the network discussion, and will not let the content of the call be leaked to people in other vehicles, ensuring privacy.

[0041] Further, when the user's mobile phone 20 does not receive a call, but the user is listening to music through the mobile phone 20.

[0042] The audio stream in the first audio track 41 is transmitted unidirectionally between the vehicle radio 30 and the helmet intercom 10. The audio stream output by the helmet intercom 10 is not incorporated into the first audio track 41, but the audio stream in the first audio track 41 is output to the helmet intercom 10. The audio stream in the second audio track 42 is transmitted bidirectionally between the vehicle radio 30 and the helmet intercom 10. The audio stream in the second audio track 42 is output to the helmet intercom 10, and the audio stream output by the helmet intercom 10 is also incorporated into the second audio track 42.

[0043] The second audio track 42 is bidirectionally transmitted with other vehicle radio stations 30. The audio stream in the second audio track 42 is output to other vehicle radio stations 30, and the audio stream input by other vehicle radio stations 30 is also merged into the second audio track 42. Before the audio stream is merged into the second audio track 42, the audio intensity is adjusted based on the distance between the vehicle radio stations 30 and other vehicle radio stations 30. Therefore, the user can listen to music without affecting other people in the network. The user can listen to music while communicating with other people in the network, which greatly improves the user experience.

[0044] Embodiment 3 See also Figure 1-Figure 10In this embodiment, the front and rear users of the two-person motorcycle 100 are respectively recorded as user A and user B; the mobile phone 20 of user A is recorded as mobile phone A21, and the helmet communicator 10 of user A is recorded as helmet communicator A11. The mobile phone 20 of user B is recorded as mobile phone B22, and the helmet communicator 10 of user B is recorded as helmet communicator B12.

[0045] When the vehicle radio 30 obtains the distance between the current vehicle radio 30 and the vehicle radio 30 inputting the audio stream according to the satellite positioning of the mobile phone 20, either the mobile phone A21 or the mobile phone B22 is used as the reference of the satellite positioning to represent the position of the current vehicle radio 30.

[0046] Furthermore, the car radio 30 establishes a first audio track A411 based on the audio stream received from the mobile phone A21, establishes a first audio track B412 based on the audio stream received from the mobile phone B22, and establishes a second audio track 42 based on the audio stream received from other car radios 30.

[0047] When a call comes in from mobile phone A21 and no call comes in from mobile phone B22, the vehicle radio 30 maintains bidirectional transmission with other vehicle radios 30, and the audio stream in the first audio track A411 is bidirectionally transmitted between the vehicle radio 30 and the helmet talker A11, the audio stream output by the helmet talker A11 is incorporated into the first audio track A411, and the audio stream in the first audio track A411 is also output to the helmet talker A11. The audio stream in the first audio track B412 is unidirectionally transmitted between the vehicle radio 30 and the helmet talker B12, the audio stream output by the helmet talker B12 is not incorporated into the first audio track B412, but the audio stream in the first audio track B412 is output to the helmet talker B12.
