Description

Technical Field

[0001] The present application is applicable to the field of wireless communication technology, and in particular, relates to a wireless call control method and apparatus, wireless call equipment, a controller and a medium. Background Art

[0002] Intercom systems are widely used in film and television shooting scenes for communication between directors and cameramen, lighting, sound engineers, stage control personnel, and for internal communication needs between staff members during large-scale events such as sports events and concerts. Commonly used intercom systems include wired intercom systems and wireless intercom systems.

[0003] Walkie-talkie is one of the most common internal communication devices. Generally, walkie-talkie is in PTT working mode. Its advantages are high transmission power, low working frequency and long transmission distance. The disadvantage is that it is a half-duplex communication mode. When speaking, you need to press the PTT button by hand to send the voice. Because the staff usually have to handle other matters with both hands, it is very inconvenient to press the PTT button to speak. In addition, since you need to use your hands to trigger the voice sending function when speaking, the beginning and end of the speech are often lost in the actual use scenario, which is fatal for film and television shooting scenes with extremely high requirements for stability and reliability. In addition, walkie-talkies generally adopt the broadcast working mode, and only one user can be in the speaking (transmitting) state at any time, which greatly limits the efficiency of communication. Another point is that the sampling rate of walkie-talkies is generally only 8kHz, and the audio quality is relatively poor. Although there are some multi-channel full-duplex wireless call systems based on walkie-talkie solutions on the market, the sound quality and the number of full-duplex are still very limited. In the case of meeting the communication scheduling time of one day, the overall equipment size is large.

[0004] During a call, the existing call system devices need to continuously transmit and process signals, which results in high power consumption and limited device usage time. In particular, in mobile intercom terminal devices, the power consumption problem is particularly prominent, affecting the user experience. Therefore, based on the need for a more lightweight wireless call system, full-duplex communication must be maintained during the call to support multiple users at the same time, and the wearing experience and comfort must be enhanced. At the same time, it can continue to ensure long-term dispatching and command, and ensure that the stability and distance of the call are not affected.

[0005] Call headsets based on Bluetooth technology can meet the needs of lightweight call terminals, but this solution lacks a sleep mechanism and cannot meet the requirements of long battery life.

[0006] Therefore, how to control the wireless communication device during a wireless call to reduce the power consumption of the wireless communication device has become an urgent problem to be solved. Summary of the invention

[0039] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0040] like Figure 1 As shown, a structural schematic diagram of a wireless call device provided in Embodiment 1 of the present application, the wireless call device includes a main control module, a voice collection unit, a voice processing module, a wireless protocol stack module, a wireless transmission module and a vibration sensor detection module, wherein the voice collection unit is connected to the voice processing module to collect audio signals in real time; the vibration sensor detection module is connected to the main control module to collect vibration sensor signals in real time; the voice processing module and the wireless protocol stack module are both connected to the main control module, and the wireless protocol stack module is connected to the voice processing module and the wireless transmission module.

[0041] The main control module is connected to the corresponding modules to realize the control of wireless calls. Specifically, the main control module realizes a wireless call control method, which can refer to the wireless call control method described in the following embodiments.

[0042] In one embodiment, if Figure 1 As shown, the wireless call device also includes a voice playback module and a wireless receiving module, wherein the voice playback module is connected to the voice processing module, and the wireless receiving module is connected to the wireless protocol module. The solution of this example can realize the reception and playback of voice, thereby realizing two-way communication.

[0043] In addition, Figure 1 A power management module is also provided in the wireless communication device, and the power management module is connected to the main control module so as to realize power supply to other modules in the wireless communication device through the main control module. Of course, when the main control module is connected to the power management module, it can also obtain the corresponding parameters (for example, power, etc.) in the power management module, and can realize more control over other modules by combining other methods and parameters in the power management module.

[0044] The wireless communication device described above records the connection relationship between the modules. For the function of each module, reference may be made to the description in the following method embodiment.

[0045] See also Figure 2 , is a flow chart of a wireless call control method provided in Embodiment 2 of the present application, wherein the wireless call control method is applied to Figure 1 Wireless communication equipment in. Figure 2 As shown, the wireless call control method may include the following steps:

[0046] Step S201, acquiring vibration sensor signals and audio signals in real time.

[0047] Among them, based on the above-mentioned wireless call device, the vibration sensor detection module is used to collect vibration sensor signals, and the voice collection unit is used to collect audio signals. Specifically, the vibration sensor detection module includes but is not limited to a wearable vibration sensor, and the voice collection unit includes but is not limited to a microphone.

[0048] For an object wearing a wireless communication device, the vibration sensing detection module can collect the vibration condition of the object, for example, characterize the vibration sensing signal with vibration acceleration. Therefore, the vibration sensing signal can characterize at least the vibration state of the object.

[0049] The audio signal is collected by driving the collector in the voice collection unit to vibrate due to the sound propagation medium, that is, the voice collection unit does not need to be in direct contact with the wearer.

[0050] The above audio signal can be Figure 1 The signal sent to the main control module after being processed by the voice processing module. In one example, the audio signal can be a signal collected by the voice collection unit. The main control module includes the voice processing module, thereby being able to process the audio signal.

[0051] Step S202, when the vibration sensing signal does not match the vibration characteristics of human tissue when speaking, or when there is no human voice feature in the audio signal, control the wireless transmission module to be in a dormant state and not transmit any signal.

[0052] The vibration characteristics of tissues when a person is speaking may refer to collecting the vibration of at least one tissue when a person is speaking, and analyzing the tissue vibration to obtain a characteristic feature, that is, when a vibration corresponding to the feature occurs, it can be determined that the person is speaking. For example, the wireless communication device is worn in the ear canal of a person, and the vibration of the tissue in the ear canal of a person is collected to analyze the unique vibration characteristics of the tissue in the ear canal when the person is speaking.

[0053] Human voice features may refer to features that characterize the spoken sounds of humans, including but not limited to Chinese, English, etc., wherein it is necessary to distinguish other sounds in nature from human voices, for example, distinguishing the noise when a machine is running from human voices, distinguishing animal calls from human voices, so as to accurately identify whether there are human voice features in the audio signal.

[0054] When the vibration sensing signal does not indicate human speech, it can be determined that at least the current wearer is not speaking, and the wireless transmission module can be controlled to sleep to avoid sending other audio data in the transmission environment, thereby reducing the power consumption of the wireless transmission module.

[0055] When there is no human speech represented in the audio signal, it can be determined that no one in the surrounding environment (including the wearer) is speaking, and the wireless transmission module can be controlled to sleep to avoid sending other audio data in the transmission environment, thereby reducing the power consumption of the wireless transmission module.

[0056] If the wireless transmission module is in a dormant state at the last moment, the dormant state is maintained after the above determination; if the wireless transmission module is in an active state at the last moment, the dormant state is changed after the above determination.

[0057] based on Figure 1A wireless call device, the audio signal is a signal collected by the voice collection unit and sent to the main control module after being processed by the voice processing module, wherein the voice processing module can complete voice noise reduction, mixing, and echo cancellation processing and then send it to the main control module, and the main control module can realize human voice recognition. Of course, in one example, the voice processing module can perform human voice recognition based on voice activity detection (VAD) and give the recognition result directly to the main control module. At this time, the voice processing module can be understood as a part of the main control module.

[0058] Step S203, when the vibration sensing signal matches the vibration feature and the human voice feature exists in the audio signal, control the wireless transmission module to be in a working state to transmit the audio signal.

[0059] Among them, only when the vibration sensing signal represents human speech and the audio signal also represents human speech, the wireless transmission module is controlled to work, so as to transmit the collected audio signal.

[0060] As the main control processor of the wireless call device, the main control module can complete audio Codec driving, peripheral control processing, sensor detection data processing, and real-time interface data interaction with the wireless protocol stack module and the voice processing module, thereby running the above control method to achieve low power consumption control of the voice processing module and the wireless protocol stack module.

[0061] In addition, the voice processing module can also complete the audio encoding and decoding functions to complete the voice data interaction with the wireless protocol stack module through structural communication or memory sharing to realize wireless transmission of signals.

[0062] The wireless protocol stack module can send and receive unlimited data, including the wireless communication protocol stack, adaptive adjustment of wireless transmission power, and switching control between sleep state and working state. The above wireless protocol stack includes but is not limited to WiFi protocol, 5G protocol, etc., and even an improved Bluetooth protocol can be used.

[0063] Optionally, after the real-time collection of the vibration sensor signal and the audio signal, the method further includes:

[0064] Extracting features from the audio signal to obtain at least one audio feature;

[0065] Matching each audio feature with a human voice feature respectively, and if there is an audio feature matching the human voice feature among all the audio features, determining that the human voice feature exists in the audio signal;

[0066] If there is no audio feature matching the human voice feature among all the audio features, it is determined that the human voice feature does not exist in the audio signal.

[0067] Among them, the method of collecting voice matching to realize the detection of voice features can effectively improve the recognition accuracy and efficiency.

[0068] Optionally, the vibration characteristics of the tissue when the human body speaks include target vibration acceleration, and after the real-time acquisition of the vibration sensing signal and the audio signal, the method further includes:

[0069] Processing the vibration sensing signal using the capacitance change to obtain a first vibration acceleration representing the vibration of human tissue;

[0070] Matching the first vibration acceleration with the target vibration acceleration, and if the first vibration acceleration matches the target vibration acceleration, determining that the vibration sensing signal matches the vibration characteristics of the tissue of the human body when speaking;

[0071] If the first vibration acceleration does not match the target vibration acceleration, it is determined that the vibration sensing signal does not match the vibration characteristics of the tissue of the human body when speaking.

[0072] Among them, the wearable vibration sensor is attached to the side of the wireless call device that is worn close to the human skin. It can capture the tiny vibrations of the tissue when the human body speaks, and send the information to the main control module. The capacitance change is used to obtain the acceleration of the tissue vibration, thereby measuring whether a sound is being made.

[0073] Audio data is collected through the microphone of the wireless call device and sent to the voice processing module. The model-based VAD voice recognition technology distinguishes between voice and non-voice and tests it. The test results are shown in Table 1:

[0074] Table 1

[0075]

[0076] In actual application scenarios, the time that people wear headsets for voice calls is generally less than 10%. Based on 10%, the power saving rate is 40-26 / (25 + 40) = 21%.

[0077] The embodiment of the present application acquires a vibration sensor signal and an audio signal in real time. When the vibration sensor signal does not match the vibration characteristics of the tissue when the human body speaks, or when the human voice characteristics do not exist in the audio signal, the wireless transmission module is controlled to be in a dormant state and not to transmit any signal. When the vibration sensor signal matches the vibration characteristics and the human voice characteristics exist in the audio signal, the wireless transmission module is controlled to be in a working state to transmit the audio signal. The working state of the wireless transmission module is controlled by the vibration sensor signal and the audio signal, thereby reducing power consumption and improving the battery life of the device when no one is speaking in wireless communication.

[0078] See also Figure 3 , is a flow chart of a wireless call control method provided in Embodiment 3 of the present application. After the wireless transmitting module is controlled to be in working state in the above step S203, as Figure 3 As shown, the wireless call control method may include the following steps:

[0079] Step S301: Acquire the wireless air interface signal strength and packet loss rate of the wireless transmission module.

[0080] Step S302: determining a target encoding mode and a target audio sampling rate for adjusting the quality of the audio to be transmitted according to the wireless air interface signal strength and the packet loss rate.

[0081] Step S303: Process the audio signal using the target encoding method and the target audio sampling rate to obtain a wireless signal to be transmitted.

[0082] Among them, the system stability can be improved to a certain extent by dynamically adjusting the voice quality. The voice adoption rate and encoding method can be adjusted comprehensively according to the wireless air interface signal strength and packet loss rate to ensure that the voice data sent is reduced during long-distance communication.

[0083] The above determination of the target encoding method and the target audio sampling rate may be performed in the form of a matching table, and the matching table is as shown in Table 2:

[0084] Table 2

[0085]

[0086] Based on the real-time calculation of the packet loss rate and signal strength of wireless air interface data transmission, the wireless voice encoding method and sampling rate are dynamically adjusted to reduce the data sent over the air interface and the power consumption during the communication process, while achieving the best experience of call stability.

[0087] See also Figure 4, is a flow chart of a wireless call control method provided in Embodiment 4 of the present application. After obtaining the wireless air interface signal strength and packet loss rate of the wireless transmission module in the above step S301, as Figure 4 As shown, the wireless call control method may include the following steps:

[0088] Step S401: determining a target transmit power according to the wireless air interface signal strength and the packet loss rate.

[0089] Step S402: using the target transmission power, adjusting the parameters of the wireless protocol stack module that controls the wireless transmission module, so that the wireless protocol stack module controls the wireless transmission module to transmit the wireless signal to be transmitted.

[0090] Among them, the transmission power matching the voice quality requirements of the call, the wireless air interface signal strength, and the packet loss rate are comprehensively adjusted to achieve dynamic adjustment of the transmission power and reduce the power consumption of the call system device as much as possible.

[0091] The above determination of the target transmission power may be performed by using a matching table, and the matching table is as shown in Table 3:

[0092] Table 3

[0093]

[0094] Among them, when the packet loss rate is 0, the transmit power is selected mainly based on the signal strength. When the packet loss rate is not 0, the transmit power is selected mainly based on the packet loss rate. At this time, during close-range voice communication, the power consumption saving rate is (40 - 25) / (25 + 40) = 23%. Therefore, according to the packet loss rate and signal strength of wireless air interface data transmission in real time, the wireless transmit power is dynamically adjusted to reduce power consumption during communication.
