The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the invention discloses a safety monitoring method and an intelligent sound box, which can send alarm information in time when a child is monitored to be dangerous. The following are detailed below.
In order to better introduce the security monitoring method disclosed in the embodiment of the present invention, the following description is first made on an intelligent sound box to which the method is applied. Referring to fig. 1, fig. 1 is an exemplary diagram of an intelligent sound box according to an embodiment of the present invention. As shown in fig. 1, a display screen 11 may be disposed on one side of the smart sound box body 10. The smart sound box may further include a camera device 20, the camera device 20 may be lifted, and after the camera device 20 is lifted, the camera device 20 may further rotate, so as to change a viewing range of the camera device 20. For example, the camera 20 may be disposed on the top of the main body 10, and the camera 20 may be turned around a rotation axis parallel to the top of the main body 10, so that the viewing range of the camera 20 may be changed at least from a placement plane (as shown in fig. 1) facing the smart sound box to a position facing the front of the display screen 11. Alternatively, the camera device 20 can rotate around a rotating shaft perpendicular to the top of the main body 10, so that the view range of the camera device 20 includes a circle with the smart sound box as the center. When the camera device 20 descends, the camera device 20 can be hidden in the groove of the main body 10, so that the intelligent sound box is more attractive in appearance.
In addition, one or more of a human body proximity sensor, a microphone, and a speaker may be provided inside the main body 10. The human body proximity sensor is used for detecting the action of a human body approaching the intelligent sound box. Illustratively, the human proximity sensor may include at least one of a pyroelectric infrared sensor, an ultrasonic sensor, and an infrared sensor. When the pyroelectric element of the pyroelectric infrared sensor detects that the infrared radiation temperature of a human body changes, electric charges are released outwards, so that a signal for indicating that the human body is detected is triggered. The ultrasonic sensor can detect the movement of a human body by using the Doppler effect of ultrasonic waves; the infrared sensor can judge that the human body approaches by detecting the infrared energy reflected after the emitted infrared rays are blocked by the outside.
Example one
Referring to fig. 2, fig. 2 is a schematic flow chart of a security monitoring method according to an embodiment of the present invention. As shown in fig. 2, the security monitoring method may include the steps of:
201. and the intelligent sound box outputs prompt information at regular time.
In the embodiment of the invention, the intelligent sound box can be placed on furniture such as a desk, a cabinet, a storage rack and a chair. Generally speaking, the placement position of the smart speaker is relatively fixed within a period of time, so that the smart speaker can be used as a card-punching point. The intelligent sound box outputs prompt information at regular time, and the prompt information is used for indicating a monitored person to arrive at a position where the distance from the intelligent sound box is smaller than a preset distance threshold value, namely indicating the monitored person to be close to the intelligent sound box so as to punch a card. The frequency of the intelligent sound box for outputting the prompt message at regular time can be preset. For example, the prompt message may be output every 1 hour or 1.5 hours.
Optionally, the prompt message may be at least one of multimedia contents such as games, videos, music, and the like. The intelligent sound box can output text or image content in the prompt message through the display screen 11; and outputting the voice content in the prompt message through a loudspeaker. Through outputting the multimedia content, the interestingness of the prompt message can be improved, and the monitored person is attracted to be close to the intelligent sound box actively.
202. The intelligent sound box judges whether the monitored person arrives at the position within a preset time after the prompt message is output; if yes, ending the process; if not, step 203 is performed.
In the embodiment of the present invention, the preset time duration may be set by referring to an average time taken by a monitored person to travel from any position of a house to a position of the smart speaker. For example, the preset time period may be set to 5 minutes, 8 minutes.
As an alternative implementation, in the embodiment of the present invention, step 202 may include, but is not limited to, the following implementation manners:
(1) the intelligent sound box controls the camera device 20 to shoot images within a preset time after the prompt information is output; if the monitored person is not identified from the image, the intelligent sound box determines that the monitored person is not detected to reach the position within the preset time.
In the embodiment of the invention, the intelligent sound box can continuously shoot within the preset time after the prompt message is output. It will be appreciated that the camera device 20 may be raised from the recess of the body 10 prior to capturing an image, to facilitate the capture by the camera device 20.
Aiming at the shot image, the intelligent sound box can extract the image characteristics of the image and match the extracted image characteristics with the preset human body image characteristics to identify whether a monitored person exists in the image. Or, a large amount of image information of the monitored person can be collected and marked in advance, and the marked image information of the monitored person is utilized to train the image recognition model; the image recognition model can be a deep neural network model, a support vector machine model and the like; the trained image recognition model can be stored at the cloud end of the intelligent sound box or the intelligent sound box locally, after the intelligent sound box shoots an image within a preset time after the prompt information is output, the image recognition model can be called, the shot image is input into the image recognition model, the output result of the image recognition model is obtained, and the output result can indicate whether a monitored person exists in the shot image or not.
In addition, as an optional implementation manner, before controlling the camera device 20 to shoot an image, the smart sound box may further obtain a first audio signal collected by a microphone of the smart sound box;
the intelligent sound box identifies the sound source position in the first audio signal;
the smart speaker controls the camera device 20 to rotate, so that the viewing range of the camera device 20 faces the sound source position.
The rotation mode of the image capturing device 20 may be rotation or inversion. In the embodiment of the invention, when the monitored person approaches the sound box, sounds such as footsteps and the like are generated. By implementing the above embodiment, the smart sound box adjusts the viewing range of the camera device 20 according to the recognized sound source position, so that the camera device 20 can face the walking direction of the monitored person, thereby increasing the possibility that the camera device 20 can shoot the monitored person.
(2) The intelligent sound box judges whether a human body proximity sensor of the intelligent sound box detects a human body within a preset time after the prompt information is output; if not, the intelligent sound box determines that the monitored person does not arrive at the position within the preset time length.
In the embodiment of the present invention, the maximum detection distance of the human body proximity sensor may be set as a preset distance threshold. When the monitored person comes within the detection range of the human body proximity sensor, the human body proximity sensor may trigger a signal indicating that a human body is detected.
Further optionally, in the implementation (2) above, after the human body proximity sensor detects a human body, the following steps may be further performed:
the intelligent sound box acquires a second audio signal acquired by a microphone of the intelligent sound box;
the intelligent sound box verifies the user voiceprint characteristics in the second audio signal by utilizing the legal voiceprint characteristics of the monitored person;
and if the user voiceprint characteristics are not consistent with the legal voiceprint characteristics, determining that the monitored person arrives at the position within the preset time length.
That is to say, by executing the above steps, it can be further determined whether the human body approaching the smart speaker is a specific monitored person or not through the voiceprint feature, so that the monitoring target of the smart speaker can be locked, and the smart speaker can monitor the safety of the specific monitored person.
In the embodiment of the present invention, if it is not detected that the monitored person reaches the above position within the preset time period, it may be considered that the monitored person may encounter a danger, so that the instruction given by the prompt message (i.e. approaching the smart speaker) cannot be executed.
203. And the intelligent sound box sends alarm information to the terminal equipment bound with the intelligent sound box.
In the embodiment of the present invention, the terminal device bound to the smart speaker may be a smart phone, a smart tablet, a smart watch, a bracelet, a personal computer, or the like, and is not limited specifically. The alarm information sent by the smart speaker may be sent to the terminal device in one or more forms of text, voice, and image through communication manners such as mail, short message, instant messaging message, and notification message, which is not limited specifically. The alarm information is used for indicating that a monitored person possibly encounters danger so as to remind a user of the terminal equipment to confirm.
In addition, the intelligent sound box attracts a monitored person to approach the intelligent sound box in a mode of outputting prompt information at regular time, so that the safety of the monitored person can be monitored, and the monitored person can be reminded of pausing in the processes of learning, working and entertainment. For example, when a child learns at home alone, the smart sound box outputs prompt information at regular time, and after seeing or hearing the prompt information, the child needs to put down the content being learned and walk from a study room to a living room where the smart sound box is placed; if intelligent sound box does not detect that child is close to intelligent sound box in predetermineeing the duration, can send alarm information to parent's terminal equipment, this alarm information is used for instructing that child's study time is too long, and the parent can contact with child in due time, reminds child's the combination of working and ease.
It can be seen that in the method described in fig. 2, the smart speaker attracts the monitored person to actively approach the smart speaker for card punching by outputting the prompt message at regular time. If the intelligent sound box does not detect that the monitored person reaches a position close to the intelligent sound box within the preset time length, alarm information is sent to the bound terminal equipment to prompt that the monitored person of a user of the terminal equipment is possibly dangerous, so that the user of the terminal equipment can know the safety condition of the monitored person in time. In addition, the intelligent sound box can remind a monitored person to pause in time in the process of learning, working and entertainment by outputting prompt information at regular time.
Example two
Referring to fig. 3, fig. 3 is a flowchart illustrating another security monitoring method according to an embodiment of the present invention. As shown in fig. 3, the security monitoring method may include the steps of:
301. and the intelligent sound box outputs prompt information at regular time.
In the embodiment of the invention, the prompt message is used for indicating that the monitored person reaches the position where the distance from the intelligent sound box is less than the preset distance threshold value. Optionally, the prompt message may be at least one of multimedia contents such as games, videos, music, and the like.
302. The intelligent sound box judges whether the monitored person arrives at the position within a preset time after the prompt message is output; if yes, ending the process; if not, step 303 is performed.
In the embodiment of the present invention, step 302 may include, but is not limited to, the following implementation manners:
(1) the intelligent sound box controls the camera device 20 to shoot images within a preset time after the prompt information is output; if the monitored person is not identified from the image, the intelligent sound box determines that the monitored person is not detected to reach the position within the preset time.
(2) The intelligent sound box judges whether a human body proximity sensor of the intelligent sound box detects a human body within a preset time after the prompt information is output; if not, the intelligent sound box determines that the monitored person does not arrive at the position within the preset time length; wherein, the maximum detection distance of the human body proximity sensor is set as a preset distance threshold.
303. The intelligent sound box acquires the verification information sent by the wearable device worn by the monitored person.
In the embodiment of the invention, the verification information is sent by manual triggering, and the verification information comprises the identification of the wireless local area network accessed by the wearable device.
For example, the wearable device may be a smart watch or a bluetooth headset, and the monitored person may trigger the verification information by continuously pressing a key on the wearable device; alternatively, the verification message may be triggered by tapping the housing of the wearable device, which is not limited in particular. The wlan id included in the check signal may be a name of the wlan or a media access control address (MAC) of the wlan, which is not limited specifically.
304. The intelligent sound box judges whether the wireless local area network accessed by the wearable equipment is consistent with the wireless local area network accessed by the intelligent sound box or not according to the verification information; if yes, ending the process; if not, step 305 to step 306 are executed.
In the embodiment of the invention, the intelligent sound box can specifically compare whether the identifier of the wireless local area network accessed by the wearable device is consistent with the identifier of the wireless local area network accessed by the intelligent sound box; if the intelligent sound box and the wearable device are consistent, the intelligent sound box and the wearable device can be considered to be connected to the same wireless local area network, the monitored person is located in a house where the intelligent sound box is located, and the monitored person is safe; if the two are not consistent, the monitored person may have left the house where the smart sound box is located, and the abnormal situation is considered, so that the steps 305 to 306 are triggered to be executed to perform alarm prompting.
By implementing the steps 303 to 304, the monitored person can punch a card by using the wearable device when the monitored person is inconvenient to walk near the smart sound box. For example, when the smart speaker outputs a prompt, the monitored person may be in a washroom and may not be able to leave for a short period of time. At this moment, the person being monitored can send check-up information through the wearable equipment manual trigger of wearing, and intelligent sound box does not send alarm information when verifying out the person being monitored in the house at intelligent sound box place according to this check-up information to can reduce the wrong report.
305. And the intelligent sound box sends alarm information to the terminal equipment bound with the intelligent sound box.
306. The intelligent sound box controls the camera device to rotate and shoot videos, and the shot videos are sent to the terminal equipment, so that a user of the terminal equipment confirms the safety of a monitored person according to the videos.
