In fig. 1, the network communication module is mainly used for connecting to a server and performing data communication with the server; the processor 1001 may call the control program of the smart audio stored in the memory 1005 and execute the control method of the smart audio according to the embodiment of the present invention.
The embodiment of the invention provides a control method of an intelligent sound box.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of an intelligent sound system according to a first embodiment of the present invention.
In this embodiment, the control method of the smart audio includes the following steps:
step S10, obtaining the current signal intensity of a target wireless earphone corresponding to a target user, and determining the target distance between the target user and the intelligent sound equipment based on the current signal intensity;
if the intelligent sound does not receive the relevant user instruction within a period of time, the intelligent sound enters a screen saver mode or a sleep mode. If the user needs to use the intelligent sound box again, the intelligent sound box needs to be awakened manually or through voice. However, the voice wake-up sound needs to be based on a specific vocabulary, so that an erroneous operation is easily generated, and the manual wake-up sound increases user operations. In order to solve the above problem, the present embodiment determines the target distance between the target user and the intelligent sound device based on the signal strength of the target wireless headset, and when it is detected that the target distance between the target user and the intelligent sound device is very close, that is, the target distance is not greater than the first distance threshold, controls the intelligent sound device to exit the screen saver mode, and enters the working mode, so that the user can perform related operations, thereby improving the user experience, avoiding the wakeup error caused by the abnormal wakeup instruction, and improving the wakeup efficiency of the intelligent sound device. Specifically, the current signal strength RSSI of the target wireless headset for identifying the target user's location may be obtained through an intelligent sound control program installed in the intelligent sound. And then converting the current RSSI into distance data to be used as the target distance between the target user and the intelligent sound box. Thus, when the target distance is determined to be smaller than a certain set value, it indicates that the user wants to perform an operation close to the smart audio. In this embodiment, a target bluetooth headset is used as a target wireless headset.
Before step S10, the method further includes:
when a connection instruction triggered by user operation is received, acquiring a wireless earphone in the connection instruction as the target wireless earphone;
and establishing wireless connection between the target wireless earphone and the intelligent sound equipment, so that the intelligent sound equipment can acquire the signal intensity of the target wireless earphone based on the wireless connection.
In this embodiment, there are two ways to obtain the RSSI of the target bluetooth headset:
1) the RSSI of the target bluetooth headset is determined by searching for nearby bluetooth devices, i.e., for situations where no wireless connection (e.g., bluetooth connection) is established between the devices.
2) And sending a signal strength acquisition instruction to the target Bluetooth headset through Bluetooth connection to acquire the RSSI of the target Bluetooth headset, namely the RSSI is suitable for the condition that wireless connection is established between the devices.
Specifically, the target user can carry out bluetooth connection with own bluetooth headset and intelligent stereo set in advance to the intelligence stereo set confirms self position based on bluetooth headset that the bluetooth is connected, in order to carry out the control process of relative intelligent stereo set. When a connection instruction triggered by user setting operation is received, a target Bluetooth earphone is determined based on the connection instruction, and Bluetooth pairing connection is carried out on the target Bluetooth earphone and the intelligent sound equipment, so that the intelligent sound equipment can acquire the signal intensity of the target wireless earphone based on the Bluetooth connection. In a specific embodiment, under the condition that the user does not connect the bluetooth headset in advance, the smart sound box exits the screen saver mode and wakes up the smart sound box when detecting that the bluetooth headset which is not more than the first distance threshold from the smart sound box exists by searching the RSSI of the nearby bluetooth devices.
Wherein, the step S10 specifically includes:
acquiring the current signal intensity of the target wireless earphone, and calculating a preset conversion formula and the current signal intensity to calculate the target distance, wherein the conversion formula is as follows:
d ^ 10^ ((abs (RSSI) -A)/(10 x n)), where d is the target distance, RSSI is the signal strength value, abs () is a function of the absolute value, A is the signal strength of the smart audio and the target wireless headset one meter away, and n is the ambient attenuation factor.
In the present embodiment, the unit of RSSI is dBm, which is generally a negative value, and reflects the degree of attenuation of a signal, and ideally, the RSSI is 0dBm without attenuation, but in practice, even if a bluetooth device is very close, the RSSI has only a strength of-50 dBm, and in the transmission process, attenuation exists, and different RSSI values can be obtained, and a relative distance can be calculated according to a conversion formula. Wherein the conversion formula is as follows: d ^ 10^ ((abs (RSSI) -A)/(10 x n)), where d is the target distance, RSSI is the signal strength value, abs () is a function of the absolute value, A is the signal strength of the smart audio and the target wireless headset one meter away, and n is the ambient attenuation factor. Because the environment is different, the corresponding parameter value of bluetooth equipment is different, therefore different bluetooth headset are connected to intelligent stereo set, and every parameter in the formula needs to do the calibration according to actual demand to confirm the environmental attenuation factor.
And step S20, when the target distance is not greater than the first distance threshold, controlling the intelligent sound box to be switched from a screen saver mode to a working mode so that the target user can perform related operations based on the display interface of the intelligent sound box.
In this embodiment, when it is determined that the converted target distance is not greater than the first distance threshold, that is, the distance between the target user and the intelligent sound device is very close, the intelligent sound device is awakened, a screen saver mode is released, that is, the intelligent sound device is controlled to be switched from the screen saver mode to a working mode, so that the target user performs related operations based on the display interface of the intelligent sound device. The first distance threshold value can be set according to actual needs.
The embodiment provides a control method of an intelligent sound device, which includes the steps of obtaining current signal intensity of a target wireless earphone corresponding to a target user, and determining a target distance between the target user and the intelligent sound device based on the current signal intensity; and when the target distance is not greater than a first distance threshold value, controlling the intelligent sound equipment to be switched from a screen saver mode to a working mode so that the target user can conveniently perform related operations based on a display interface of the intelligent sound equipment. Through the mode, the target distance between the target user and the intelligent sound box is determined based on the signal intensity of the target wireless earphone, and when the target distance between the target user and the intelligent sound box is detected to be very close, namely the target distance is not greater than the first distance threshold, the intelligent sound box is controlled to exit the screen saver mode and enter the working mode, so that the user can conveniently perform related operations, the user experience is improved, meanwhile, the awakening error caused by the abnormal awakening instruction is avoided, the awakening efficiency of the intelligent sound box is improved, and the technical problem that the awakening efficiency of the existing intelligent sound box awakening mode is low is solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of an intelligent sound system according to a second embodiment of the present invention.
Based on the foregoing embodiment shown in fig. 2, in this embodiment, after step S10, the method further includes:
step S30, when the target distance is greater than the first distance threshold, determining whether the target distance is not greater than a second distance threshold, where the first distance threshold is smaller than the second distance threshold;
step S40, when the target distance is not greater than the second distance threshold, determining whether the current movement state of the target user is an approaching state based on the target distance;
when the target distance is not greater than the second distance threshold, the step of determining whether the current moving state of the target user is a close state based on the target distance specifically includes:
when the target distance is not greater than the second distance threshold, acquiring a historical distance corresponding to the target user from pre-stored historical data;
and judging whether the current moving state is the approaching state or not based on the target distance and the historical distance.
And sequencing the historical distance and the target distance according to the sequence of distance detection time, and determining that the current moving state is the approaching state when the sequenced distance value is in a descending state.
And step S50, when the current movement state is the approaching state, controlling the intelligent sound equipment to be switched from a screen saver mode to a working mode so that the target user can conveniently perform related operations based on the display interface of the intelligent sound equipment.
In this embodiment, in order to further improve the control accuracy of the smart audio, when it is determined that the target distance is greater than the first distance threshold, that is, the distance between the target user and the smart audio is not very close to each other, it is further determined whether the target distance is not greater than a second distance threshold. And when the target distance is not greater than the second distance threshold, namely the target user is close to the intelligent sound box, further combining the current movement state of the target user to determine whether to wake up the screen of the intelligent sound box. The first distance threshold is smaller than the second distance threshold, and the second distance threshold can be set according to actual needs. Specifically, the process of determining the current moving state of the target user is as follows: and acquiring historical data prestored in a database or a cache, wherein the historical data is obtained by carrying out signal intensity detection on the target Bluetooth headset based on each signal intensity detection period and converting the signal intensity detection to obtain corresponding historical distance data. The distance of the target Bluetooth headset is detected every 3 seconds within 1 minute of 9:00-9:01, and the detection time and the distance data are stored in an associated mode to serve as historical data. And sequencing according to the sequence of the distance detection time, such as the distances corresponding to 3 seconds, 6 seconds, 9 seconds and the like of 1 minute. And when the sorted distance values are determined to be in a descending state, the descending state is mainly presented as a whole, namely the target user is determined to be approaching to the intelligent sound gradually, namely the current moving state of the target user is determined to be the approaching state. Namely, the target user is closer to the intelligent sound box, and the target user is approaching the intelligent sound box gradually, so that the intelligent sound box can be controlled to be switched from a screen saver mode to a working mode, and the target user can perform related operations based on the display interface of the intelligent sound box.
Referring to fig. 4, fig. 4 is a flowchart illustrating a control method for an intelligent sound system according to a third embodiment of the present invention.
Based on the foregoing embodiment shown in fig. 3, in this embodiment, after step S10, the method further includes:
step S60, when the target distance is greater than a second distance threshold, determining whether the current moving state of the target user is a distant state based on the target distance;
wherein, if the target distance is greater than a second distance threshold, the step of determining whether the current moving state of the target user is a far state based on the target distance specifically includes:
if the target distance is greater than a second distance threshold, acquiring a historical distance corresponding to the target user from pre-stored historical data, and sequencing the historical distance and the target distance according to the distance detection time sequence;
and judging whether the current moving state of the target user is a far state or not based on the change state of the sorted distance values.
And step S70, when the current movement state is a far-away state, controlling the intelligent sound equipment to be switched from the working mode to the screen saver mode so as to reduce the power consumption of the intelligent sound equipment.
In this embodiment, in order to reduce power consumption of the smart audio, when it is detected that the target user is far away from the smart audio, the smart audio is controlled to be switched from the working mode to the screen saver mode. When the target distance between the target user and the intelligent sound box is larger than a second distance threshold value, namely the target user is far away from the intelligent sound box, the current moving state of the target user is further obtained. And when the current moving state of the target user is far away, controlling the intelligent sound equipment to enter a low power consumption mode, such as a screen saver mode. Specifically, the process of determining the current moving state of the target user is as follows: and acquiring historical data prestored in a database or a cache, wherein the historical data is obtained by carrying out signal intensity detection on the target Bluetooth headset based on each signal intensity detection period and converting the signal intensity detection to obtain corresponding historical distance data. The distance of the target Bluetooth headset is detected every 3 seconds within 1 minute of 9:00-9:01, and the detection time and the distance data are stored in an associated mode to serve as historical data. And sequencing according to the sequence of the distance detection time, such as the distances corresponding to 3 seconds, 6 seconds, 9 seconds and the like of 1 minute. And when the sorted distance values are determined to be in the increasing state, the increasing state is mainly displayed on the whole, namely the target user is determined to be away from the intelligent sound box gradually, namely the current moving state of the target user is determined to be the away state. And controlling the intelligent sound to be switched from the working mode to the screen saver mode so as to reduce the power consumption of the intelligent sound. In a specific embodiment, when it is detected that the target distance between the target user and the smart audio is greater than a third distance threshold, the smart audio may be directly controlled to be switched from the working mode to the screen saver mode, so as to reduce power consumption of the smart audio. The third distance threshold is greater than the second distance threshold, and the third distance threshold can be set according to actual needs.
In further embodiments, to reduce false positives, the first distance threshold, the second distance threshold, and the third distance threshold may be determined through a number of experiments. The RSSI can be read repeatedly by reducing the time interval of the RSSI in a circulating manner, and the RSSI is compared with a set distance threshold value, so that the distance values measured repeatedly are smaller than the threshold value.
