Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to illustrate the technical solutions proposed in the present application, the following description is made by specific embodiments.
The following describes a power adjustment method for underwater communication according to the embodiment of the present application. The power adjustment method is applied to the wearable intelligent device. The wearable smart device is equipped with a mechanical wave transceiver such that the wearable smart device is capable of transmitting and receiving mechanical wave signals (e.g., ultrasonic signals) through the mechanical wave transceiver. Referring to fig. 1, the implementation flow of the power adjustment method is described in detail as follows:
step 101, when a user wearing the wearable intelligent device is in a wading scene, acquiring a distance between the user and a preset target, or establishing mechanical wave communication connection with the preset target through the mechanical wave transceiver.
In the embodiment of the application, the wearable intelligent device can acquire the use scene where the user (i.e. the wearer) is currently located. Specifically, when entering a wading scene (for example, a user swimming in a place such as a reservoir, a sea, a river or a swimming pool, or entering a water park for playing, etc.), the user can manually click a virtual button of "scene selection" on the wearable intelligent device to input a scene selection instruction, so that the wearable intelligent device can passively learn that the user is currently in the wading scene based on the scene selection instruction; or, the wearable intelligent device can sense the moisture in the environment through the humidity sensor and the like carried by the wearable intelligent device, and if the moisture in the environment is too much, the wearable intelligent device can also actively know that the user is in the wading scene currently; or, the wearable intelligent device can determine the current position of the user through the positioning system carried by the wearable intelligent device, if the user is currently located in a wading place (such as a water park, a reservoir, a sea, a river or a swimming pool, etc.), the wearable intelligent device can also actively know that the user is currently located in the wading place, and the means for the wearable intelligent device to know the current use place of the user is not limited.
In one application scenario, once the user is found to be currently in a wading scenario, the distance between the user and the preset target may be obtained from the safety consideration of the user. By way of example only, the preset target may be other users than the user (i.e., wearer) of the wearable smart device, who may also be wearing other wearable smart devices (hereinafter other devices), through which the user may communicate with other devices worn by other users in time when play with water is dangerous, so that the other users may arrive at the user to provide assistance. Alternatively, the preset target may be a shore (e.g., a coast, a river bank, or a pool bank). This is because in a practical scenario, when a user is in the sea, in a river or in a swimming pool, there is not necessarily other people who are also playing, but the bank usually has a security guard, and the security guard may wear other devices, and when the user is in danger, the user can communicate with other devices worn by the security guard on the bank in time through the wearable intelligent device, so that the security guard can arrive at the user to provide assistance. The preset target may be set to be shore in view of the low body position of the user in the sea, in the river or in the swimming pool. Alternatively, the preset target may be other devices directly.
In another application scenario, once the user is found to be currently in a wading scenario, the wearable smart device may be triggered to establish a mechanical wave communication connection with other devices through the mechanical wave transceiver for user safety considerations. The explanation of this other device is explained above and will not be repeated here. It should be noted that the mechanical wave communication connection should follow the following protocol: the wearable intelligent device and other devices can send out signals with the same transmitting power, and the information of the currently used transmitting power can be encoded in the signals sent out by the wearable intelligent device. Assuming that the wearable smart device emits a signal at a transmit power x, the transmit power x will be encoded in the signal; once other devices receive the signal, the transmitting power currently used by the wearable intelligent device can be decoded and obtained, and the other devices can feed back the signal to the wearable intelligent device by using the same transmitting power (namely transmitting power x) so as to establish the mechanical wave communication connection between the two devices.
And 102, determining the target transmitting power of the mechanical wave transceiver according to the distance or the mechanical wave communication connection.
In this embodiment of the present application, for the application scenario in which the distance between the user and the preset target is obtained in step 101, the developer of the wearable intelligent device may perform multiple test operations on the communication between the wearable intelligent device and other devices based on the mechanical wave signal in advance in the wading scenario for testing, so as to find the minimum transmission power of the mechanical wave transceiver required by each different communication distance under the condition that the communication quality is satisfied. Based on the test result, the research and development manufacturer can preset a comparison table, and the comparison table stores the corresponding relations between different distance intervals and the target transmitting power. Referring to the table, table 1 gives a simple example of this comparison table.
Distance interval Target transmit power
(0,x1] P1
(x1,x2] P2
…… ……
TABLE 1
After the distance between the user and the preset target is obtained, the wearable intelligent device can firstly determine a distance interval in which the distance falls, and then determine the corresponding target transmitting power by referring to a preset comparison table.
Alternatively, a developer of the wearable intelligent device may fit a calculation formula of the target transmitting power based on the test result. The wearable intelligent device can directly determine the corresponding target transmitting power through the calculation formula after obtaining the distance between the user and the preset target.
For the application scenario of step 101 of establishing a mechanical wave communication connection with other devices through the mechanical wave transceiver, the wearable intelligent device may directly determine the transmit power used for the mechanical wave communication connection as the target transmit power.
It will be appreciated that, considering that the user is likely to move during play, this may cause a change in the distance between the user and the preset target, and also may cause a change in the communication distance between the wearable smart device and other devices, based on this, steps 101 and 102 may be triggered and executed periodically, so as to implement an update of the distance between the user and the preset target and an update of the target transmitting power.
Step 103, when receiving the communication request, controlling the mechanical wave transceiver to send out a communication signal with the target transmitting power.
In the embodiment of the application, when the user encounters an emergency in the wading scene, the user can actively input a communication request to the wearable intelligent device. By way of example only, a physical distress button may be provided on the wearable smart device, and the user may simply press the physical distress button to input a communication request to the smart device. In order to avoid false touch, a preset time period can be set, and the communication request is input to the intelligent device only when the user presses the physical distress key for a long time to reach the preset time period.
The wearable intelligent device can also autonomously detect whether a user encounters an emergency in the wading scene. By way of example only, considering that a user is drowned, often both hands may shake involuntarily and irregularly, the wearable smart device may detect its own motion state through its mounted gyroscopes and/or inertial measurement units. If the motion state of the communication device in a certain time period is detected to be irregular shaking, the communication request can be actively generated. Or if the wearable intelligent device is provided with a water pressure sensor, whether the wearable intelligent device enters a deep underwater area or not can be detected through the water pressure sensor. If the communication request is detected to enter the underwater deeper region, the communication request can be actively generated.
It will be appreciated that the communication request received by the wearable smart device is used to indicate that the user is currently in an emergency situation, at which time the wearable smart device is required to communicate with other devices in time via the mechanical wave transceiver, so that the wearer of the other devices can be notified to go to the wearable smart device (i.e. the user's place) to provide assistance. Since the target transmit power of the mechanical wave transceiver has been determined by step 102, the mechanical wave transceiver may be controlled to transmit a communication signal at the target transmit power.
In some embodiments, referring to fig. 2, the wearable smart device can also be equipped with a camera. The wearable intelligent device may acquire the distance between the wearable intelligent device and the preset target through the camera, and the operation of acquiring the distance between the user and the preset target may specifically include:
a1, acquiring the current environment image of the user through a camera.
After the user is determined to be in the wading scene, the camera can be started, and the current environment of the user is shot through the camera, so that an environment image is obtained.
A2, detecting whether the preset target exists in the environment image.
The environmental image is analyzed through the trained object recognition model, so that whether a preset object exists in the environmental image, such as whether other users exist, whether other devices exist or whether the shoreside exists or not, can be detected. It will be understood that the operation of detecting whether other users exist in the environmental image by this step specifically refers to detecting whether face images of other users exist in the environmental image.
It will be appreciated that the camera may also capture images of the user's face when capturing images of the environment. In order to distinguish the face image of the user from the face images of other users, the wearable intelligent device may pre-capture and record the face image of the user. And subsequently, after the environment image is obtained, matching each face image in the environment image with the face image of the user. If the matching is successful, the face image of the user is determined, and if the matching is failed, the face images of other users are determined.
A3, if the preset target exists in the environment image, calculating the distance between the user and the preset target through a preset image ranging technology.
Once it is determined that a preset target exists in the environmental image, the wearable intelligent device can calculate the distance between the user and the preset target according to a preset image ranging technique. The image ranging technique may be embodied as a monocular ranging technique considering that the camera that the wearable smart device is typically mounted on is a monocular camera.
In some embodiments, considering that many tourists in a wading place such as a water park may exist, when the preset target is other users, a situation that a plurality of other users exist in the environment image may occur. To cope with this, the above step A3 may specifically include:
A31, if more than two other users exist in the environment image, determining the target other users based on the size of the picture occupied by each other user in the environment image.
The target other user refers to the other user closest to the user. Since each other user presented in the environment image necessarily follows the imaging rule of "near-far-small", it can be determined that the face image of the other user closer to the user generally occupies a larger picture, and the face image of the other user farther from the user generally occupies a smaller picture. Therefore, when more than two face images of other users can be detected in the environment image, the target other users can be determined based on the size of the picture occupied by the face images of the other users in the environment image; that is, the other user corresponding to the face image having the largest screen occupied in the environment image is determined as the target other user.
Referring to fig. 3, fig. 3 shows a schematic representation of an environment image. In the environment image, a face image 1 corresponds to other users A, a face image 2 corresponds to other users B, and a face image 3 corresponds to other users C. Since the face image 2 occupies the largest screen in the environment image, the other user B can be determined as the target other user.
A32, calculating the distance between the user and other users of the target through the image ranging technology.
Only the target other users may be considered in performing ranging. That is, only the distance between the user and the other users of the target is calculated, so that the influence of the other users far away from the user on the calculation of the distance is avoided.
In some embodiments, whether or not the wearable smart device is equipped with a camera, the distance between the user and the preset target can be obtained directly through the mechanical wave transceiver. In this case, the preset target specifically refers to other devices. The operation of obtaining the distance between the user and the preset target may specifically include:
b1, transmitting a first detection signal at a specified first transmission power through the mechanical wave transceiver.
The specified first transmit power may be a predetermined fixed power, for example, a theoretical maximum transmit power. Considering that the scheme of the application is mainly used for guaranteeing the endurance of the wearable intelligent device, the specified first transmission power can be gradually increased from the first preset power to the second preset power in each preset detection period until the second detection feedback signal is received. For example, the first preset power is recorded as P 10 The second preset power is recorded as P 20 The mechanical wave transceiver may be controlled by P at a specified first transmit power for the first 200 milliseconds every 1 second 10 Gradually increase to P 20 To emit a first probe signal, and the mechanical wave transceiver is controlled not to emit the first probe signal for the next 800 milliseconds. For example only, the first preset power may be 0 and the second preset power may be a theoretical maximum transmit power of the mechanical wave transceiver. It will be appreciated that once the first probe feedback signal transmitted by the other device based on the first probe signal is received, the transmission of the probe signal (i.e., suspending other devices in the vicinity of the probe) may be suspended until the next time the distance from the preset target needs to be acquired, and the mechanical wave transceiver may be triggered again to transmit the probe signal at the specified first transmission power.
And B2, when the mechanical wave transceiver receives a first detection feedback signal sent by the other equipment based on the first detection signal, calculating the distance between the user and the other equipment according to the sending time of the first detection signal and the receiving time of the first detection feedback signal.
The propagation speed of mechanical waves emitted by the wearable smart device itself in a medium (e.g. water and air) is known. Thus, when receiving the first detection feedback signal fed back by other equipment based on the first detection signal, the distance between the user and the detected other equipment can be estimated approximately by a time-of-flight method according to the emission time of the first detection signal, the receiving time of the first detection feedback signal and the propagation speed of the mechanical wave.
In some embodiments, the wearable smart device can establish a mechanical wave communication connection with other devices by:
c1, transmitting a second detection signal with a designated second transmitting power through the mechanical wave transceiver.
And C2, if the mechanical wave transceiver receives a second detection feedback signal sent by the other equipment based on the second detection signal, and the signal intensity of the second detection feedback signal is not lower than a preset first signal intensity threshold value, gradually reducing the second transmitting power until the signal intensity of the second detection feedback signal reaches the first signal intensity threshold value.
And C3, if the other equipment does not receive the second detection feedback signal transmitted by the second detection signal, or if the signal intensity of the received second detection feedback signal is lower than the first signal intensity threshold value, gradually increasing the second transmitting power until the second detection feedback signal is received and the signal intensity of the second detection feedback signal reaches the first signal intensity threshold value.
The specified second transmit power may initially be a predetermined fixed power. From the protocol given in the foregoing, it is known that other devices remain synchronized with the transmit power of the wearable smart device. In order to ensure subsequent cruising, the wearable intelligent device should find the minimum transmitting power required for normal communication with other nearest devices through the established mechanical wave communication connection. Based on the method, after the mechanical wave communication connection is initially established, the wearable intelligent device can adjust the adopted second transmitting power until the adopted second transmitting power can just enable the wearable intelligent device to be in normal communication with other devices, the current second transmitting power can be determined to be the target transmitting power subsequently, and the wearable intelligent device can just conduct normal communication with the other devices based on the determined target transmitting power.
For example only, assume that the second transmit power is initially set to an intermediate value x1. After the wearable intelligent device sends out the second detection signal based on the second transmission power x1, if the second detection feedback signal is not received or the signal strength of the second detection feedback signal is too small (smaller than the first signal strength threshold), the second transmission power can be increased to x2 (x 2 > x 1), and the second detection signal is continuously sent out based on the second transmission power x 2; similarly, assuming that a second sounding feedback signal having a signal strength up to (i.e., equal to or slightly greater than) the first signal strength threshold is received until the second transmit power increases to xn, the stopping may occur. Subsequent step 102 may determine xn as the target transmit power.
For example only, assume that the second transmit power is initially set to an intermediate value y1. After the wearable intelligent device sends out the second detection signal based on the second transmission power y1, if the second detection feedback signal is received and the signal intensity of the second detection feedback signal is too large (far larger than the first signal intensity threshold value), the second transmission power can be reduced to y2 (y 1 > y 2), and the second detection signal is continuously sent out based on the second transmission power y 2; similarly, assuming that a second sounding feedback signal having a signal strength up to (i.e., equal to or slightly greater than) the first signal strength threshold is received until the second transmit power decreases to yn, the stopping may occur. Subsequent step 102 may determine yn as the target transmit power.
In some embodiments, to ensure that the wearable smart device can establish a good mechanical wave communication connection with other devices in an emergency, the wearable device may make dynamic adjustments to the target transmit power. Based on this, after step 103, the power adjustment method further includes:
if the mechanical wave transceiver receives the communication feedback signal based on the communication signal and the signal strength of the communication feedback signal is not lower than a preset second signal strength threshold value, the current target transmitting power is maintained.
If the communication feedback signal based on the communication signal is not received, or if the signal strength of the received communication feedback signal is lower than the second signal strength threshold, the target transmitting power is gradually increased until the communication feedback signal is received and the signal strength of the communication feedback signal reaches the second signal strength threshold.
It can be understood that if the communication signal is sent at the current target transmission power and then feedback (i.e. the communication feedback signal) is received, and the signal strength of the communication feedback signal is good (greater than the second signal strength threshold value), the wearable intelligent device can normally communicate with other devices under the current target transmission power, so that the user can be ensured to be notified to other people in time under the emergency. At this point, the wearable smart device may remain in communication with other devices at the current target transmit power until the user is out of emergency and the operation of the mechanical wave transceiver is not stopped. For example only, after receiving a command to stop communication entered by a user, or after the location of the wearable intelligent device leaves the wading location, the user may be considered to be away from the emergency.
Otherwise, if the communication feedback signal based on the communication signal is not received, or if the signal strength of the received communication feedback signal is still lower than the second signal strength threshold, it is considered that other users possibly closest to the user cannot wear other devices capable of communicating with the wearable intelligent device, or the positions of the user and/or other users are moved, so that the communication distance is increased. In this regard, the wearable smart device may gradually increase the target transmit power such that the communication signal may be communicated farther based on the increase in the target transmit power. Therefore, if other remote users wear other devices capable of communicating with the wearable intelligent device, the communication feedback signal with good signal intensity can be received by the communication of the wearable intelligent device. At this time, the wearable intelligent device can maintain the target transmitting power when receiving the good communication feedback signal, so as to realize continuous communication with other devices. In addition, if the signal strength of the received communication feedback signal is lower than the second signal strength threshold, the current wearable intelligent device is considered to have poor communication quality although being capable of communicating with other nearest devices. In order to ensure good communication between the two parties in the wading scene, the wearable intelligent device can gradually increase the target transmitting power, so that the wearable intelligent device and the other devices are connected with each other in a good communication mode based on mechanical waves.
In some extreme cases, it may be that no other user in the vicinity of the user is carrying another device capable of communicating with the wearable smart device, which may result in that the communication feedback signal cannot be received or the signal strength of the received communication feedback signal is still below the second signal strength threshold even if the wearable smart device communicates to increase its target transmit power to the theoretical maximum transmit power. In this regard, the wearable smart device may be triggered to initiate its secure alert functions, such as: outputting a reminding message in the form of an audio signal and/or an optical signal to attract the attention of other users; and/or the current location is sent to emergency contacts or the like set by the user, without limitation to the specific form of the secure alert function.
In some embodiments, if the preset target cannot be detected by the camera and the preset target cannot be detected by the mechanical wave transceiver or a mechanical wave communication connection is established with other devices while the user is in the wading scene, the current user is considered to be in the wading scene alone. In this case, the user is at risk, whether or not in an emergency situation. Therefore, in this case, it is possible to try to send the current location to the emergency contact set by the user in a short message or the like, so as to remind the other party of the danger of the user who is looking at the user as soon as possible.
As can be seen from the above, according to the embodiment of the present application, for a wearable intelligent device having a mechanical wave transceiver mounted thereon, when a user is in a wading scene, the distance between the user and a preset target may be obtained, or a mechanical wave communication connection may be established between the mechanical wave transceiver and the preset target, and a target transmitting power of the mechanical wave transceiver may be determined according to the distance or the mechanical wave communication connection, so that, subsequently, when a communication request is received, the mechanical wave transceiver may be controlled to transmit a communication signal with the target transmitting power. The process can adaptively adjust the transmitting power of the mechanical wave transceiver according to the distance between the user and a preset target (such as other users) or the mechanical wave communication connection established with the preset target (such as other equipment) in the wading scene, so that the communication between the user and the preset target is not affected, the resource waste caused by the fact that the mechanical wave transceiver adopts unnecessary overlarge transmitting power is avoided, and the cruising duration of the wearable intelligent equipment is ensured.
Corresponding to the power adjustment method for the underwater communication provided above, the embodiment of the application also provides a power adjustment device for the underwater communication. The power adjustment device is applied to a wearable smart device that includes a mechanical wave transceiver. As shown in fig. 4, the power adjustment device 400 includes:
