Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
FIG. 1 is an implementation environment of intercom device communication, including a second intercom device and a first intercom device, according to an exemplary embodiment; the second intercom device and the first intercom device establish communication connection through a frequency modulation mode, so that communication between the second intercom device and the first intercom device is achieved. The second intercom device and the first intercom device are adjusted to the same frequency, so that communication connection is established. The second intercom device may be any device having an intercom function, for example, the second intercom device may be an intercom, or a wearable device such as a watch and a bracelet having an intercom function. The first intercom device may be any device having an intercom function, for example, the first intercom device may also be an intercom, or a wearable device such as a watch or a bracelet having an intercom function. The maximum output power of the second intercom device may be 0.5W, 2W, 5W, 10W, or the like, and similarly, the maximum output function of the first intercom device may be 0.5W, 2W, 5W, 10W, or the like. The maximum output power of the second intercom device may be the same as or different from the maximum output power of the first intercom device.
It should be noted that the implementation environment may include a plurality of second intercom devices, where the first intercom device may establish communication connection with the plurality of second intercom devices through a frequency modulation manner, so as to implement communication between the first intercom device and the plurality of second intercom devices.
In the embodiment of the disclosure, when the second intercom device and the first intercom device communicate, the second intercom device and/or the first intercom device may adjust output power of the second intercom device and/or the first intercom device according to a communication distance between the second intercom device and the first intercom device.
Fig. 2 is a flow chart illustrating a method of intercom communication according to an exemplary embodiment, as shown in fig. 2, including the following steps.
In step S201, the first intercom device receives the first audio signal transmitted by the second intercom device, and determines the signal quality of the first audio signal.
In step S202, the first intercom device determines a first output power of the first intercom device according to the signal quality.
In step S203, the first intercom device sets the output power of the first intercom device to a first output power, and transmits the second audio signal acquired by the first intercom device through the first output power.
In the embodiment of the disclosure, the quality of the first audio signal is determined by receiving the first audio signal sent by the second intercom device, so that the first output power of the first intercom device is determined, and compared with the case that the audio signal is transmitted by using the maximum transmission power, the second audio signal obtained by transmitting the first output power reduces the loss of the battery of the intercom device and prolongs the service time of the intercom device.
Fig. 3 is a flow chart illustrating another method of intercom communication, according to an exemplary embodiment, including the following steps, as shown in fig. 3.
In step S301, the first intercom device establishes a communication connection with the second intercom device.
When the first intercom device and the second intercom device are communicated, the first intercom device and the second intercom device are communicated through a frequency modulation mode.
In step S302, the second intercom device transmits the first audio signal to the first intercom device via the communication connection.
It should be noted that, the first audio signal may be a first audio signal sent after the first intercom device and the second intercom device establish a communication connection, or may be a non-first audio signal sent after the second intercom device and the first intercom device establish a communication connection.
Another point to be noted is that after the first intercom device establishes a connection with the second intercom device, the first intercom device may actively transmit the third audio signal to the second intercom device through the communication connection. When the first intercom device transmits the third audio signal for the first time, the first intercom device can transmit the third audio signal through the maximum output power of the first intercom device, can transmit the third audio signal through the minimum output power of the first intercom device, and can transmit the third audio signal through the appointed output power. The specified output power may be any output power between the minimum output power and the maximum output power, for example, the specified output power may be an average value of the minimum output power and the maximum output power, or the like.
In step S303, the first intercom device receives the first audio signal transmitted by the second intercom device, and determines the signal quality of the first audio signal.
The signal quality may be characterized by a signal to noise ratio or signal strength. In one possible implementation, when the signal quality is characterized by a signal-to-noise ratio, the step of the first intercom device determining the signal quality of the first audio signal may be: the first intercom equipment obtains the voice, the noise and the harmonic wave of the first audio signal according to the first audio signal, obtains first audio power according to the power of the voice, the power of the noise and the power of the harmonic wave, obtains second audio power according to the power of the noise and the power of the harmonic wave, and determines the ratio of the first audio power to the second audio power as the susceptance ratio of the first audio signal.
The first intercom device determines the sum of the power of voice, the power of noise and the power of harmonic wave as first audio power, and determines the sum of the power of noise and the power of harmonic wave as second audio power.
In another possible implementation, when the signal quality is characterized by an audio signal strength, the step of the first intercom device determining the signal quality of the first audio signal may be: the first intercom device determines the signal strength of the first audio signal and takes the signal strength of the first audio signal as the signal quality of the first audio signal.
Wherein the stronger the signal strength of the first audio signal, the higher the quality of the first audio signal; the weaker the signal strength of the first audio signal, the lower the quality of the first audio signal.
It should be further noted that, because the first intercom device may establish communication connection with the plurality of second intercom devices at the same time, when the first intercom device communicates with the plurality of second intercom devices at the same time, the first intercom device may receive a plurality of first audio signals within a preset time range, and the first intercom device selects one first audio signal with the lowest signal quality from the plurality of first audio signals, and then determines the signal quality of the selected first audio signal. The first intercom device may further select one of the plurality of first audio signals whose signal quality is close to the average value, and then determine the signal quality of the selected first audio signal.
In step S304, the first intercom device determines a communication distance between the second intercom device and the first intercom device according to the signal quality.
In one possible implementation manner, the correspondence between the signal quality and the communication distance is stored in the first intercom device, and the communication distance between the second intercom device and the first intercom device is determined from the correspondence between the signal quality and the communication distance according to the signal quality.
In another possible implementation manner, the relation between the signal quality range and the communication distance is stored in the first intercom device, the signal quality range in which the signal quality is located is determined according to the signal quality, and the communication distance between the second intercom device and the first intercom device is determined from the corresponding relation between the signal quality range and the communication distance.
In step S305, the first intercom device determines the first output power of the first intercom device according to the communication distance.
In this step, the disclosed embodiments enumerate three possible implementations:
in a first possible implementation, different communication distance ranges correspond to different output powers. The first intercom device determines a communication distance range in which the communication distance is located according to the communication distance, and determines first output power of the first intercom device from a corresponding relation between the communication distance range and the output power according to the communication distance range.
The first intercom device stores a correspondence between a communication distance range and output power, and each different communication distance range corresponds to one output power, for example, the first intercom device may be an intercom with a transmitting power of 0.5W, and the correspondence between the communication distance range and the output power is as follows: within 100 meters, 0.1W,100-500 meters 0.2W,500-1000 meters 0.3W,1000-2000 meters 0.4W and above 2000 meters 0.5W. When the communication distance is 1200 meters, the first intercom device determines that the first output power of the first intercom device is 0.4W from the corresponding relation between the communication distance range and the output power.
In a second possible implementation manner, the first intercom device determines an adjustment coefficient, where the adjustment coefficient is used to characterize a ratio between the communication distance and the output power of the first intercom device, and adjusts the current second output power of the first intercom device through the adjustment coefficient to obtain the first output power. After the first intercom device determines the adjustment coefficient, the ratio of the communication distance to the adjustment coefficient is determined as the first output power.
The adjustment coefficient may be an adjustment coefficient preset by the first intercom device; the first intercom device may also be determined according to the historical output power and the historical communication distance corresponding to the historical output power. The historical output power and the historical communication distance corresponding to the historical output power can be the output power and the communication distance of the audio signal with better quality.
In the embodiment of the disclosure, the first intercom device determines the adjustment coefficient according to the historical output power and the historical communication distance corresponding to the historical output power, and then adjusts the current second output power based on the adjustment coefficient, so that the accuracy of adjustment can be improved.
For example, the first intercom device may be an intercom with a transmitting power of 0.5W, the adjustment coefficient is 6000, the current second output power is 0.2W, when the communication distance between the second intercom device and the first intercom device is 900 meters, the first intercom device may need to be adjusted to 0.15W according to the adjustment coefficient, and the first intercom device reduces the current second output power to obtain the first output power.
In a third possible implementation manner, the first intercom device stores a preset communication distance, and the first intercom device compares the communication distance with the preset communication distance. When the communication distance is larger than the preset communication distance, the second output power is increased to obtain the first output power, wherein the second output power is the current output power of the first intercom equipment; when the communication distance is equal to the preset communication distance, the second output power is used as the first output power; and when the communication distance is smaller than the preset communication distance, reducing the second output power to obtain the first output power.
In a first implementation manner, the first intercom device determines a first value, and increases the second output power by the first value to obtain the first output power. The first intercom equipment stores a preset first value, and the second terminal acquires the stored first value. The first intercom device may also determine a first value based on a first difference between the preset communications distance and the communications distance. Accordingly, the step of determining the first value by the first intercom device may be: the first intercom equipment determines a first difference value, and obtains a first value corresponding to the first difference value from the corresponding relation between the difference value and the first value according to the first difference value.
The first intercom equipment determines a second numerical value, and reduces the second output power by the second numerical value to obtain the first output power. The first intercom device stores a preset second value, and the second terminal acquires the stored second value. The first intercom device may also determine the second value based on a first difference between the preset communications distance and the communications distance. Accordingly, the step of determining the second value by the first intercom device may be: the first intercom equipment determines a first difference value, and obtains a second value corresponding to the first difference value from the corresponding relation between the difference value and the second value according to the first difference value.
In a second implementation manner, the first intercom device stores a preset communication distance, a third output power, a fourth output power and a fifth output power, wherein the third output power is smaller than the fourth output power, and the fourth output power is smaller than the fifth output power. The first intercom device compares the communication distance with a preset communication distance. When the communication distance is larger than the preset communication distance, taking the fifth output power as the first output power; when the communication distance is equal to the preset communication distance, taking the fourth output power as the first output power; and when the communication distance is smaller than the preset communication distance, taking the first output power as the first output power.
For example, referring to fig. 4, the foregoing second intercom device and the first intercom device are both an intercom, where the preset communication distance of the first intercom device is 1000 meters, the signal-to-noise ratio is 12db, the first intercom device receives a first audio signal sent by the second intercom device, and the first intercom device characterizes signal quality according to the signal-to-noise ratio of the first audio signal, and when the signal-to-noise ratio is greater than 12db, it indicates that the communication distance between the second intercom device and the first intercom device is smaller than the preset communication distance; when the signal-to-noise ratio is equal to 12db, the signal quality of the first audio signal is unchanged, which means that the communication distance between the second intercom device and the first intercom device is equal to a preset communication distance; when the susceptance ratio is less than 12db, the signal quality of the first audio signal is reduced, indicating that the communication distance between the second intercom device and the first intercom device is equal to the preset communication distance.
It should be noted that, before the first intercom device adjusts up the current second output power, the first intercom device determines whether the second output power is already the maximum output power of the first intercom device; when the second output power is not the maximum output power of the first intercom device, executing the step of increasing the second output power to obtain the first output power; when the second output power is already the maximum output power of the first intercom device, the second output power is taken as the first output power.
In step S306, the first intercom device sets the output power of the first intercom device to a first output power, and transmits the second audio signal acquired by the first intercom device through the first output power.
The first intercom device sets the output power to the first output power at which the second audio signal is transmitted. After the transmission is completed, the first intercom device enters a standby state until receiving the first audio signal transmitted by the second intercom device, and the step S303 starts to be executed.
The second audio signal may be an audio signal that replies to the first audio signal, and after the first intercom device receives the first audio signal, whether there is an audio signal is detected; if the audio signal exists, the audio signal is collected, and the collected audio signal is used as a second audio signal.
It should be noted that, the step of the first intercom device collecting the second audio signal and the steps S304 to S305 have no time sequence. It is possible to collect the second audio signal first and then perform steps S304-S305, or it is possible to perform steps S304-S305 first and then collect the second audio signal, or collect the second audio signal during the process of performing steps S304-S305.
It should be further noted that, after the first intercom device receives the first audio signal sent by the second intercom device, the user identifier corresponding to the first audio signal may also be identified based on the first audio signal; when the user identifier is a user identifier of a specified type, setting the output power of the first intercom device as the maximum output power of the first intercom device; when the user identification is not the user identification of the specified type, a step of determining a communication distance between the second intercom device and the first intercom device according to the signal quality is performed, that is, step S304 is performed.
For example, the step of the first intercom device identifying the user identification may be: the first intercom equipment identifies the user identification corresponding to the first audio signal through a voiceprint identification technology on the received first audio signal; or the first intercom device analyzes the received first audio signal, wherein the first audio signal comprises the user identification, and the first intercom device identifies the user identification corresponding to the first audio signal.
After the first intercom device identifies the user identifier corresponding to the first audio signal, the step of judging the user type may be: the first intercom device stores a corresponding relation table of the user identification and the user type, and the first intercom device determines whether the user identification is the user identification of the appointed type according to the corresponding relation table.
The appointed type can be a boss, a family, appointed personnel and the like, the output power of the first intercom equipment is set to be the maximum output power of the first intercom equipment, and at the moment, the problem of electric quantity saving is not considered, so that the communication quality is preferentially ensured.
After the first intercom device collects the second audio signal, the content of the second audio signal can be judged. It is determined whether to adjust the output power of the first intercom device based on the content of the second audio signal. The step of the first intercom device judging the content of the second audio signal may be: the first intercom equipment analyzes the acquired second audio signal to obtain the content contained in the second audio signal; setting the output power of the first intercom device to the maximum output power of the first intercom device when the specified keyword is included in the content of the second audio signal; when the specified keyword does not exist in the content of the second audio signal, step S304 is performed to determine the communication distance between the second intercom device and the first intercom device according to the signal quality. The keywords may be a bank card, a password, a time point, a word preset by a user, and the like, and the content of the keywords is not particularly limited in the embodiment of the disclosure.
It should be noted that, after the second intercom device receives the second audio signal sent by the first intercom device, the output power of the second intercom device may also be adjusted according to the above method.
In the embodiment of the disclosure, the quality of the first audio signal is determined by receiving the first audio signal sent by the second intercom device, so that the communication distance between the second intercom device and the first intercom device is determined, the first output power of the first intercom device is adjusted according to the communication distance, and the obtained second audio signal is transmitted through the first output power, compared with the mode that the audio signal is transmitted by using the maximum transmission power, the consumption of a battery of the intercom device is reduced, and the service time of the intercom device is prolonged.
