It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] Refer to the following Figures 1 to 2 A multi-channel communication intercom device and method according to some embodiments of the present invention will be described.

[0052] like Figure 1 As shown, one embodiment of the present invention provides a multi-channel communication intercom device, which is applied to a motor vehicle and includes: a plurality of communication channels for receiving and sending data, a processing module, an acquisition module, a scene determination module, and a channel selection module;

[0053] The processing module is configured to receive a communication connection instruction triggered by a user;

[0054] The acquisition module is configured to acquire communication environment data when the communication connection instruction is an intercom communication connection instruction;

[0055] The scenario determination module is used to determine the current intercom communication scenario based on the communication environment data;

[0056] The channel selection module is configured to select a corresponding first communication channel from a plurality of communication channels for communication according to the current intercom communication scenario.

[0057] It will be appreciated that, in the embodiments of the present invention, multiple communication channels for receiving and sending data are included, which may be mobile communication network communication units, wireless local area network communication units, broadband wireless access network communication units, broadband wireless mobile communication network communication units, wireless metropolitan area network communication units, cellular mobile network communication units, etc. Each communication channel has different communication quality parameters such as communication performance and power consumption, thereby being able to adapt to communication needs in different scenarios.

[0058] In the present invention, the current intercom communication scenario is determined based on the communication environment data, and the corresponding first communication channel is selected for communication based on the correspondence between the intercom communication scenario and the communication channel (which can be set by the user or automatically set through big data analysis).

[0059] In some possible implementations of the present invention, the multi-channel communication intercom device may further include an adjustment module (not shown in the figure), which can adjust its own angle according to the direction of the user's sound source to facilitate the collection of the user's sound data.

[0060] Using the technical solution of this embodiment, the multi-channel intercom device includes multiple communication channels for receiving and sending data, a processing module, an acquisition module, a scenario determination module, and a channel selection module; the processing module is used to receive a communication connection instruction triggered by the user; the acquisition module is used to obtain communication environment data when the communication connection instruction is an intercom communication connection instruction; the scenario determination module is used to determine the current intercom communication scenario based on the communication environment data; and the channel selection module is used to select a corresponding first communication channel from multiple communication channels for communication based on the current intercom communication scenario. The solution of the present invention not only provides multiple communication channels for communication to accommodate different communication needs, but also automatically selects the corresponding first communication channel based on different intercom scenarios, making it more intelligent.

[0061] It should be known that Figure 1 The block diagram of the multi-channel communication intercom device is for illustration only, and the number of modules shown therein does not limit the protection scope of the present invention.

[0062] In some possible implementations of the present invention, the multi-channel communication intercom device further includes a verification module and a rights management module:

[0063] The acquisition module is further used to obtain the identity information of the user;

[0064] The verification module is used to perform security verification on the identity information;

[0065] The authority management module is used to grant the user the authority to trigger the communication connection instruction when the user passes the security verification.

[0066] It is understandable that the user's identity information may be one or more of voice (voiceprint) data, face data, fingerprint data or iris data.

[0067] When the identity information is sound (voiceprint) data, the process of security verification of the identity information may be: obtaining the user's historical sound data, preprocessing the historical sound data, removing noise (i.e., non-speech signals and silent speech signals, etc.) to obtain a speech signal s; obtaining the length L of the speech signal; pre-emphasizing s according to the formula s1(i)=s(i)-0.99*s(i-1) to obtain a new signal s1, where i belongs to [2, L]; calculating the power spectrum density based on the number of sampling points per frame being 320 and the offset between the starting points of adjacent frames being 160; taking the integer part of (L-320) / 160 and adding 1 to obtain the value obtained as the number of frames and using this value to verify the new signal. Signal s1 is framed; each frame is windowed to obtain a short-term signal; each short-term signal is fast Fourier transformed to obtain the corresponding linear spectrum; the linear spectrum is squared modulo the square to obtain a discrete power spectrum; the obtained discrete power spectrum is filtered through a triangular bandpass filter bank, and the logarithmic energy X of the filter bank output is calculated; X is discrete cosine transformed to obtain MFCC parameters; the MFCC parameters are input into a neural network for training to obtain a voiceprint recognition model; the sound (voiceprint) data is preprocessed, and the MFCC parameters of the voiceprint to be identified are extracted and input into the voiceprint recognition model to determine whether it is a registered and legitimate voiceprint, that is, whether the user is a legitimate user. When the user passes security verification, the user is granted permission to trigger the communication connection instruction. This solution ensures communication security.

[0068] It is understandable that, in the embodiments of the present invention, different communication channels may be set for different voiceprints to carry out communication, so as to meet the personalized communication needs of users and further ensure communication security.

[0069] It should be noted that in order to further ensure security, secondary security verification can be performed by collecting facial data. The process of using facial data for security verification can be: S0, obtain a facial image, grayscale process and normalize the facial image, and calculate the gradient of each pixel; S1, select a detection window from the image according to the window sliding step; S2, select a block from the detection window according to the block sliding step; divide the block into sub-block units, perform bin direction projection in the sub-block, calculate the projection sum, perform normalization in the block, construct HOG features in the block, and check whether it reaches the last block. If not, return to S2; if so, determine whether it reaches the last window. If not, return to S1. If so, output the feature description; S3, input the feature description into the trained face recognition model to obtain the recognition result, and determine whether the user is a legitimate user based on the recognition result.

[0070] In some possible implementations of the present invention, the communication environment data includes voice data, video data, natural environment data, operation data of the motor vehicle, time data, and location data; the scene determination module is configured to determine the current intercom communication scene based on the communication environment data, specifically:

[0071] Recognizing the voice data and extracting key language information therefrom;

[0072] Identifying the video data and extracting key image information therefrom;

[0073] The key language information, the key image information, the natural environment data, the operation data of the motor vehicle, the time data, and the location data are input into a pre-stored intercom communication scene model to determine a current intercom communication scene.

[0074] It can be understood that in order to more intelligently determine the current scenario in which the user uses intercom communication, in an embodiment of the present invention, a pre-trained intercom communication scenario model is stored. By inputting the collected / extracted key language information (such as "the engine is broken", "the car is stalled", "there is a big mud pit ahead", "I need to contact my teammates", etc.), the key image information (such as vehicle smoking images, accident scene images, etc.), the natural environment data (such as temperature, light intensity, smoke concentration, etc.), the motor vehicle operation data (such as rotation speed, speed, water tank temperature, fuel consumption, etc.), the time data, the location data and other data into the intercom communication scenario model, the current intercom communication scenario can be determined.

[0075] In some possible implementations of the present invention, the multiple communication channels include a 5G communication channel, a WIFI communication channel, and an Internet of Things communication channel; the channel selection module is configured to select a corresponding first communication channel from the multiple communication channels for communication according to the current intercom communication scenario, specifically:

[0076] When the current intercom communication scenario is that the motor vehicle fails, selecting the 5G communication channel as the first communication channel for communication;

[0077] When the current intercom communication scenario is communicating with vehicles in a traveling fleet, the WIFI communication channel or the Internet of Things communication channel is selected for communication.

[0078] It is understandable that in an embodiment of the present invention, when the current intercom communication scenario is that the motor vehicle has a malfunction, a 5G communication channel with a wider communication range and guaranteed communication quality can be selected as the first communication channel for communication to ensure timely rescue; when the current intercom communication scenario is communicating with vehicles in a fleet of vehicles, it means that the communication distance may not be too far, and a WIFI communication channel or an IoT communication channel with lower power consumption can be preferentially selected for communication. Of course, communication channel matching situations can also be set in various scenarios. For example, when making confidential calls, a special encrypted communication channel can be used; when conducting video communication, voice and image data can be divided into multiple communication channels for transmission to ensure high communication quality.

[0079] In some possible implementations of the present invention, when the first communication channel is the Internet of Things communication channel, the processing module is further configured to:

[0080] Search for all IoT communication base stations on the road in real time;

[0081] Sort the IoT communication base stations by signal strength;

[0082] When the ranking position of the signal strength of the current base station connected to is less than a preset value, the communication connection is switched to the IoT communication base station with the strongest signal strength.

[0083] It is understood that the IoT communication base station may be a facility such as a smart streetlight or smart traffic light integrated with an IoT communication base station. When a motor vehicle is on the move, it generally travels through the coverage areas of different communication base stations. To provide a stable and continuous communication connection, in an embodiment of the present invention, a real-time search is performed for all IoT communication base stations on the road and the base stations are ranked by signal strength. When the ranking position of the signal strength of the current base station connected to the vehicle is less than a preset value, the communication connection is switched to the IoT communication base station with the strongest signal strength to ensure that good communication quality is maintained.

[0084] See Figure 2 Another embodiment of the present invention provides a multi-channel intercom communication method, which is applied to a motor vehicle. The multi-channel intercom communication method includes:

[0085] receiving a communication connection instruction triggered by a user;

[0086] When the communication connection instruction is an intercom communication connection instruction, acquiring communication environment data;

[0087] Determining a current intercom communication scenario based on the communication environment data;

[0088] According to the current intercom communication scenario, a corresponding first communication channel is selected from a plurality of communication channels for communication.

[0089] It will be appreciated that, in the embodiments of the present invention, multiple communication channels for receiving and sending data are included, which may be mobile communication network communication units, wireless local area network communication units, broadband wireless access network communication units, broadband wireless mobile communication network communication units, wireless metropolitan area network communication units, cellular mobile network communication units, etc. Each communication channel has different communication quality parameters such as communication performance and power consumption, thereby being able to adapt to communication needs in different scenarios.

[0090] In the present invention, the current intercom communication scenario is determined based on the communication environment data, and the corresponding first communication channel is selected for communication based on the correspondence between the intercom communication scenario and the communication channel (which can be set by the user or automatically set through big data analysis).

[0091] In some possible implementations of the present invention, the multi-channel communication intercom device may further include an adjustment module (not shown in the figure), which can adjust its own angle according to the direction of the user's sound source to facilitate the collection of the user's sound data.

[0092] The technical solution of this embodiment receives a user-triggered communication connection instruction. When the communication connection instruction is an intercom communication connection instruction, communication environment data is obtained; based on the communication environment data, the current intercom communication scenario is determined; and based on the current intercom communication scenario, a corresponding first communication channel is selected from multiple communication channels for communication. This solution not only provides multiple communication channels to accommodate different communication needs but also automatically selects the corresponding first communication channel based on the intercom scenario, making it more intelligent.

[0093] In some possible implementations of the present invention, before the step of receiving a communication connection instruction triggered by a user, the step further includes:

[0094] Obtaining identity information of the user;

[0095] Performing security verification on the identity information;

[0096] When the user passes the security verification, the user is granted permission to trigger the communication connection instruction.

[0097] It is understandable that the user's identity information may be one or more of voice (voiceprint) data, face data, fingerprint data or iris data.

Signal s1 is framed; each frame is windowed to obtain a short-term signal; each short-term signal is fast Fourier transformed to obtain the corresponding linear spectrum; the linear spectrum is squared modulo the square to obtain a discrete power spectrum; the obtained discrete power spectrum is filtered through a triangular bandpass filter bank, and the logarithmic energy X of the filter bank output is calculated; X is discrete cosine transformed to obtain MFCC parameters; the MFCC parameters are input into a neural network for training to obtain a voiceprint recognition model; the sound (voiceprint) data is preprocessed, and the MFCC parameters of the voiceprint to be identified are extracted and input into the voiceprint recognition model to determine whether it is a registered and legitimate voiceprint, that is, whether the user is a legitimate user. When the user passes security verification, the user is granted permission to trigger the communication connection instruction. This solution ensures communication security.

[0099] It is understandable that, in the embodiments of the present invention, different communication channels may be set for different voiceprints to carry out communication, so as to meet the personalized communication needs of users and further ensure communication security.

[0100] It should be noted that in order to further ensure security, secondary security verification can be performed by collecting facial data. The process of using facial data for security verification can be: S0, obtain a facial image, grayscale process and normalize the facial image, and calculate the gradient of each pixel; S1, select a detection window from the image according to the window sliding step; S2, select a block from the detection window according to the block sliding step; divide the block into sub-block units, perform bin direction projection in the sub-block, calculate the projection sum, perform normalization in the block, construct HOG features in the block, and check whether it reaches the last block. If not, return to S2; if so, determine whether it reaches the last window. If not, return to S1. If so, output the feature description; S3, input the feature description into the trained face recognition model to obtain the recognition result, and determine whether the user is a legitimate user based on the recognition result.

[0101] In some possible implementations of the present invention, the communication environment data includes voice data, video data, natural environment data, operation data of the motor vehicle, time data, and location data; and the step of determining the current intercom communication scenario based on the communication environment data includes:

[0102] Recognizing the voice data and extracting key language information therefrom;

[0103] Identifying the video data and extracting key image information therefrom;

[0104] The key language information, the key image information, the natural environment data, the operation data of the motor vehicle, the time data, and the location data are input into a pre-stored intercom communication scene model to determine a current intercom communication scene.

[0105] It can be understood that in order to more intelligently determine the current scenario in which the user uses intercom communication, in an embodiment of the present invention, a pre-trained intercom communication scenario model is stored. By inputting the collected / extracted key language information (such as "the engine is broken", "the car is stalled", "there is a big mud pit ahead", "I need to contact my teammates", etc.), the key image information (such as vehicle smoking images, accident scene images, etc.), the natural environment data (such as temperature, light intensity, smoke concentration, etc.), the motor vehicle operation data (such as rotation speed, speed, water tank temperature, fuel consumption, etc.), the time data, the location data and other data into the intercom communication scenario model, the current intercom communication scenario can be determined.

[0106] In some possible implementations of the present invention, the multiple communication channels include a 5G communication channel, a WIFI communication channel, and an Internet of Things communication channel; and the step of selecting a corresponding first communication channel from the multiple communication channels for communication according to the current intercom communication scenario includes:

[0107] When the current intercom communication scenario is that the motor vehicle fails, selecting the 5G communication channel as the first communication channel for communication;

[0108] When the current intercom communication scenario is communicating with vehicles in a traveling fleet, the WIFI communication channel or the Internet of Things communication channel is selected for communication.

[0109] It is understandable that in an embodiment of the present invention, when the current intercom communication scenario is that the motor vehicle has a malfunction, a 5G communication channel with a wider communication range and guaranteed communication quality can be selected as the first communication channel for communication to ensure timely rescue; when the current intercom communication scenario is communicating with vehicles in a fleet of vehicles, it means that the communication distance may not be too far, and a WIFI communication channel or an IoT communication channel with lower power consumption can be preferentially selected for communication.
