Detailed Description
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 should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
It should be understood that, although the steps in the flowcharts in the embodiments of the present application are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and may be performed in other orders unless explicitly stated herein. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, in different orders, and may be performed alternately or at least partially with respect to other steps or sub-steps of other steps.
It should be noted that, step numbers such as S100 and S200 are used herein for the purpose of more clearly and briefly describing the corresponding contents, and do not constitute a substantial limitation on the sequence, and those skilled in the art may perform S200 first and then S100 in the specific implementation, but these should be within the protection scope of the present application.
It needs to be understood that intelligent security equipment has all been used in present many places, like intelligent doorbell, intelligent monitoring camera etc. detect someone and get into after treating the detection zone, just open camera, microphone and loudspeaker module to make user side can carry out the video telephony with the personnel before the intelligent security equipment and communicate, but if there are other people to speak beside the user, perhaps there is the environmental disturbance sound, make user side can not hear the content of speaking of the personnel before the intelligent security equipment, lead to the conversation quality to descend.
Therefore, the invention provides an intelligent security control method which is applied to intelligent security equipment.
It should be understood that, referring to fig. 10, in practical applications, in order to improve the call quality and reduce the influence of ambient noise, a dual-microphone endfire array may be used to pick up sound. At this time, the double microphones in the whole machine are symmetrically arranged with the middle position of the whole machine, that is, if the user stands at the position of the center line of the whole machine, the speaking voice can be simultaneously acquired by the left microphone and the right microphone.
If the audio signal picked up by the left microphone in the array is added to the audio signal picked up by the right microphone, a "superimposed audio signal" is formed. If the sound comes from 90 degrees and the user is in the middle position of the left microphone and the right microphone, namely the left microphone and the right microphone acquire the same amplitude and the same phase of the audio, the sound after superposition becomes 2 times, namely the reception is enhanced.
In an embodiment of the present invention, referring to fig. 1, the present invention provides an intelligent security control method including:
s100, detecting whether a person enters a detection area to be detected;
step S200, when a person is determined to enter a zone to be detected, a left microphone and a right microphone are started, and a first audio signal picked up by the left microphone and a second audio signal picked up by the right microphone are obtained;
in this embodiment, intelligent security equipment can include that a person gets into the determine module and rather than the controller of electricity connection, and the person gets into determine module and is used for detecting whether someone has got into in waiting to detect the area, in intelligent security equipment's the distinguishable region promptly.
Optionally, personnel get into the detection subassembly and can adopt infrared sensing device to realize, infrared sensor for example, infrared sensor can acquire treat in the detection zone that infrared sensor predetermines the infrared radiation value in the detection range promptly, and generate infrared radiation detection information to controller, because the human body can be to external radiation infrared ray, consequently the controller can be based on infrared radiation detection information and confirm that there is the people to get into when treating the infrared radiation value in the detection zone about conventional human infrared radiation value.
Optionally, personnel's detection subassembly can also adopt photoelectric sensor to realize, for example set up a set of grating in waiting to detect the district, when waiting that there is the personnel in the detection zone to enter into, can block the route between photoelectric sensor's transmitting terminal and the receiving terminal, make the receiving terminal can't receive the infrared light that the transmitting terminal launches, photoelectric sensor output someone entering signal to controller this moment, low level signal for example, when nobody gets into in waiting to detect the district, the receiving terminal can normally receive the infrared light that the transmitting terminal launches, photoelectric sensor can output nobody entering signal to controller this moment, high level signal for example, the controller alright whether someone gets into waiting to detect the district according to the signal determination that photoelectric sensor transmitted.
In this embodiment, after determining that a person enters the area to be detected, the controller may control the left microphone and the right microphone to switch from the stop operating state to the start operating state, so as to obtain the first audio signal picked up by the left microphone and the second audio signal picked up by the right microphone.
Step S300, calculating a time difference between the acquired first audio signal and the acquired second audio signal, adjusting audio parameters of the first audio signal and the second audio signal according to the time difference so that the adjusted audio parameters of the first audio signal are consistent with the adjusted audio parameters of the second audio signal, and overlapping the adjusted first audio signal and the adjusted second audio signal to generate audio information of the region to be measured.
Optionally, the microphone outputs an analog signal, the controller may be integrated with an analog-to-digital converter and a digital-to-analog converter, and the controller may convert the received first audio signal and the second audio signal, which are analog signals, into digital signals, and then adjust audio parameters of the first audio signal/the second audio signal according to the time difference, that is, adjust the phase and amplitude of the first audio signal/the second audio signal.
Optionally, the microphone may further directly integrate an analog-to-digital converter, and directly output the first audio signal and the second audio signal as digital signals.
In this embodiment, a timing module and a calculating module may be disposed inside the controller, so as to calculate a time difference between the acquisition of the first audio signal and the acquisition of the second audio signal. Alternatively, the controller may start timing when the first/second audio signal is received and stop timing when another audio signal is received, and the timing time is the time difference.
It should be understood that, in practical applications, because it is difficult for a person in the detection area to be located at a position facing the intelligent security device, that is, facing a midpoint position on a connection line where the left microphone and the right microphone are located (as can be seen from the above, the left microphone and the right microphone can simultaneously receive audio signals with the same amplitude and phase, and after superposition, the audio signals are 2 times the amplitude of the actual audio), a certain difference may exist between the phase and the amplitude of the first audio signal picked up by the left microphone and the amplitude of the second audio signal picked up by the right microphone, and therefore, the audio parameter of the first audio signal and the audio parameter of the second audio signal can be adjusted through the time difference, so that the adjusted audio parameter of the first audio signal is consistent with the adjusted audio parameter of the second audio signal.
Specifically, referring to fig. 3, in this embodiment, the step of adjusting the audio parameters of the first audio signal and the second audio signal to make the adjusted audio parameters of the first audio signal and the adjusted audio parameters of the second audio signal consistent, and superimposing the adjusted first audio signal and the adjusted second audio signal to generate the audio information of the region to be measured specifically includes:
step S310, when the first audio signal is obtained, after the first audio signal is delayed according to the time difference and the second audio signal is subjected to audio amplitude compensation according to the time difference, the first audio signal and the second audio signal are superposed to generate audio information of the area to be detected;
step S320, when the second audio signal is obtained first, after the second audio signal is delayed according to the time difference and the first audio signal is subjected to audio amplitude compensation according to the time difference, the second audio signal and the first audio signal are superimposed to generate audio information of the region to be detected.
In this embodiment, referring to fig. 9, when the controller receives the first audio signal first, that is, receives the first audio signal from the left microphone first (which indicates that the person in the area to be detected is closer to the left microphone at this time), the controller performs delay processing on the obtained first audio signal according to the currently obtained time difference. At this time, the phase of the first audio signal after the delay processing is consistent with the phase of the second audio signal, but since the distance between the person to be detected and the left microphone is closer, the amplitude of the audio signal picked up by the two microphones at this time is different, that is, the audio amplitude of the first audio signal is different from the audio amplitude of the second audio signal, in this embodiment, the audio amplitude of the second audio signal is smaller than the audio amplitude of the first audio signal, that is, the volume (unit: decibel dB) of the second audio signal picked up by the second microphone is smaller than the volume (unit: decibel dB) of the first audio signal, and the difference value of the volumes can be obtained by the volume difference calculation formula (1) preset in the controller
Δ ═ 20 × lg (1+ T × 340) volume difference calculation formula (1)
Where T is equal to the time difference and 340m/S is the speed of sound.
In this embodiment, the controller may perform gain on the audio amplitude of the second audio signal adjusted to be the digital signal, so as to increase the volume of the second audio signal by the difference calculated by the volume difference, so that the audio amplitude of the first audio signal is as large as the audio amplitude of the second audio signal. At this time, the controller superimposes the first audio signal after the delay processing and the second audio signal after the gain processing to generate audio information of a region to be detected.
Similarly, in this embodiment, when the controller receives the second audio signal first, the controller performs delay processing on the second audio signal according to the same process, performs gain processing on the first audio signal, and superimposes the first audio signal after the gain processing and the second audio signal after the delay processing to generate the audio information to be detected.
It can be understood that, in this embodiment, intelligent security equipment still generally will be being provided with loudspeaker module to the realization will treat the sound output in the detection zone to the user side, so that the user can communicate with the personnel in treating the detection zone. Therefore, in the present embodiment, the controller outputs the audio information of the region to be detected to the user side through the speaker module. Therefore, the reception quality of the speaking voice of the personnel in the detection area to be treated by the intelligent security equipment can be improved, the voice of the visitor heard by the user side is loud and clear, and the call quality of the intelligent security equipment is effectively improved.
According to the technical scheme, whether a person enters a to-be-detected area is detected, when the person enters the to-be-detected area, a left microphone and a right microphone are started, a first audio signal picked up by the left microphone and a second audio signal picked up by the right microphone are obtained, the time difference between the first audio signal and the second audio signal is calculated, audio parameters of the first audio signal and the second audio signal are adjusted, the adjusted audio parameters of the first audio signal are consistent with the adjusted audio parameters of the second audio signal, and the adjusted first audio signal and the adjusted second audio signal are superposed to generate audio information of the to-be-detected area. Therefore, the reception quality of the speaking voice of the personnel in the detection area to be treated by the intelligent security equipment can be improved, the voice of the visitor heard by the user side is loud and clear, and the call quality of the intelligent security equipment is effectively improved.
Referring to fig. 2, in an embodiment of the present invention, an infrared sensor is further disposed in the whole device, and the step of detecting whether a person enters the detection area specifically includes:
step S110, detecting an infrared radiation value in a region to be detected, and generating infrared detection information;
the steps of determining that a person enters a detection area to be detected specifically comprise:
step S210, determining that a person enters the region to be detected when the infrared radiation value in the region to be detected is determined to be within a preset human body radiation value range according to the infrared detection information.
In this embodiment, the infrared sensor detects an infrared radiation value in the region to be detected, and generates corresponding infrared detection information to the controller. When personnel enter the infrared detection area, because the human body can radiate infrared rays outwards, the controller can determine that the personnel currently enter the area to be detected when the infrared radiation in the current area to be detected is within a preset human body radiation value range according to the infrared detection information. The preset human body radiation value interval can be preset by research personnel according to the conventional value of the human body infrared radiation value and stored in the controller of the intelligent security equipment. Therefore, whether a person enters the detection area to be detected or not can be detected in an infrared identification mode. Simultaneously, whether the infrared sensor is adopted to carry out personnel and get into and wait to detect the region, adopt surveillance camera head to compare, can the effectual consumption that reduces whole intelligent security equipment.
Referring to fig. 4, in an embodiment of the present invention, the intelligent security device further includes an image sensing component, and the step of turning on the left microphone and the right microphone and acquiring the first audio signal picked up by the left microphone and the second audio signal picked up by the right microphone when it is determined that a person enters the area to be detected includes:
step S220, when a person is determined to enter the area to be detected, starting an image sensing assembly and acquiring image information of the person in the area to be detected;
in this embodiment, can also integrate face identification module in the controller, when confirming to wait to detect the intraductal personnel that have, the controller in the intelligent security equipment controls image sensor subassembly earlier, for example the camera is opened to shoot the image of waiting to detect the intraductal personnel of district and carry out action recognition, for example facial action recognition to image information, and generate corresponding personnel action information.
Step S230, performing action recognition on the image information to generate corresponding personnel action information;
step S240, when it is determined that the mouth movement of the person in the region to be detected is a speaking movement according to the person movement information, turning on the left microphone and the right microphone, and acquiring a first audio signal picked up by the left microphone and a second audio signal picked up by the right microphone.
In this embodiment, if the controller can normally recognize the face image according to the person motion information, and recognizes the mouth motion of the person in the region to be detected as a speaking motion, it is determined that the person in the current region to be detected has an intention to talk, and the left microphone and the right microphone are turned on to obtain a first audio signal picked up by the left microphone and a second audio signal picked up by the right microphone. For example, within a certain preset time, when the mouth opening ratio action times of the person in the area to be detected reaches the preset times, the mouth movement of the person in the current area to be detected is determined as the speaking action, and the left microphone and the right microphone are turned on when the person in the area to be detected has the conversation intention.
In another embodiment, referring to fig. 5, when it is determined that a person enters the area to be detected, the step of turning on the left microphone and the right microphone and acquiring the first audio signal picked up by the left microphone and the second audio signal picked up by the right microphone further includes:
and step S250, controlling the left microphone and the right microphone to keep a non-operating state when determining that the mouth action of the person in the region to be detected is not a speaking action according to the person action information.
In this embodiment, if the controller cannot normally recognize the face image in the region to be detected according to the person action information, for example, if the person currently in the region to be detected is only a passerby that passes by, the face image of the person currently in the region to be detected cannot be recognized, or if the mouth action of the person currently in the region to be detected is not a speaking action, it is determined that the person currently in the region to be detected has no intention to talk. At this time, the controller controls the left microphone and the right microphone to keep the non-operating state. Therefore, when the personnel in the area to be detected are determined to have no conversation intention, the left microphone and the right microphone are not controlled to be started, and therefore the power consumption of the intelligent security equipment is reduced.
Referring to fig. 6, in an embodiment of the present invention, when the step of turning on the left microphone and the right microphone and acquiring the first audio signal picked up by the left microphone and the second audio signal picked up by the right microphone and the step of calculating a time difference between the acquisition of the first audio signal and the acquisition of the second audio signal are performed when it is determined that a person enters the region to be detected, and the step of adjusting the audio parameters of the first audio signal and the second audio signal according to the time difference, so that the audio parameters of the adjusted first audio signal and the adjusted audio parameters of the second audio signal are consistent, and the adjusted first audio signal and the adjusted second audio signal are superimposed to generate audio information of the region to be detected, the intelligent security control method further includes:
step S400, when the audio amplitude in the to-be-detected area is determined to reach the preset audio amplitude according to the first audio signal or the second audio signal, judging that the person in the to-be-detected area has the conversation intention;
calculating the time difference between the acquired first audio signal and the acquired second audio signal, adjusting the audio parameters of the first audio signal and the second audio signal according to the time difference so as to make the audio parameters of the adjusted first audio signal consistent with the audio parameters of the adjusted second audio signal, and superposing the adjusted first audio signal and the adjusted second audio signal to generate audio information of the region to be measured:
step S340, when the fact that the person in the area to be detected has the conversation intention is determined, calculating and acquiring the time difference between the first audio signal and the second audio signal, adjusting the audio parameters of the first audio signal and the second audio signal to enable the audio parameters of the adjusted first audio signal to be consistent with the audio parameters of the adjusted second audio signal, and overlapping the adjusted first audio signal and the adjusted second audio signal to generate the audio information of the area to be detected;
step S500, when the audio amplitude in the zone to be detected is determined not to reach the preset audio amplitude according to the first audio signal or the second audio signal, judging that the person in the zone to be detected does not have the intention of communication;
calculating the time difference between the acquired first audio signal and the acquired second audio signal, adjusting the audio parameters of the first audio signal and the second audio signal according to the time difference so as to make the audio parameters of the adjusted first audio signal consistent with the audio parameters of the adjusted second audio signal, and superposing the adjusted first audio signal and the adjusted second audio signal to generate audio information of the region to be measured:
and step S350, when the fact that the person in the area to be detected does not have the intention of calling is determined, the first audio signal and the second audio signal are not adjusted.
In the present embodiment, it can be seen from the above that when the mouth movement of the person in the region to be detected is determined as the speaking movement, the left microphone and the right microphone are turned on. In this embodiment, when the controller receives the first audio signal and the second audio signal, the controller does not start the audio signal processing on the two signals according to the time difference at the first time. But the audio amplitude of the first audio signal/the audio amplitude of the second audio signal is compared with the preset audio amplitude.
If the audio amplitude of any one of the audio amplitude of the first audio signal and the audio amplitude of the second audio signal is greater than the preset audio amplitude, it may be determined that the audio amplitude in the current detection region reaches the preset audio amplitude. The controller can regard that the person in the current detection area actually has the speaking intention at this moment, and then the first audio signal and the second audio signal are subjected to signal processing according to the content of the embodiment to obtain the audio information of the detection area. Wherein the preset audio amplitude is set by a research and development staff.
If the audio amplitude of the first audio signal and the audio amplitude of the second audio signal are not greater than the preset audio amplitude, that is, the audio amplitude in the detection region does not reach the preset audio amplitude, for example, the sound volume represented by the preset audio amplitude is 30 decibels, the sound volume represented by the audio amplitude of the first audio signal is 20 decibels, and the sound volume represented by the audio amplitude of the second audio signal is 15 decibels. At this moment, the controller judges that the person in the current detection area does not have the speaking intention, and the first audio signal and the second audio signal are not processed until the audio amplitude of any audio signal reaches the preset audio amplitude. Therefore, the power consumption of the intelligent security equipment is effectively reduced.
In addition, in another embodiment, it should be understood that, when detecting that there is a person in the detection area, the current intelligent security device may start the camera and the working function module, such as a communication system. However, in practical application, people in the detection area often just pass by, rather than performing voice conversation, and at this time, if the working module other than the camera is turned on, the working power of the working module is generally more than watt level, so that the working power consumption of the intelligent security device is easily increased.
Therefore, it can be understood that the controller can start other working modules after determining that the person in the area to be detected has the speaking intention so as to meet the conversation requirement of the user and the person in the area to be detected; optionally, the working module may include a speaker module, and when it is determined that the person in the area to be detected has the intention to speak, the speaker module may be turned on to realize that the audio information of the area to be detected, which is picked up by the microphone, is played to the user side through the speaker module; optionally, the working module may also be a wireless communication module, such as a bluetooth module, and when it is determined that a person in the area to be detected has an intention to speak, the sending function of the wireless communication module may be started, so that the audio information of the area to be detected, which is picked up by the microphone, is transmitted to a mobile terminal, such as a mobile phone, of a user through a wireless communication network. If the fact that the person in the current region to be detected does not have the speaking intention is determined, other working modules can be controlled to be in a stop working state or a standby state, and therefore power consumption of the intelligent security equipment is reduced.
Referring to fig. 7, in an embodiment of the present invention, a speaker module is further disposed in the whole device, and when it is determined that the audio amplitude in the to-be-detected area reaches a preset audio amplitude according to the first audio signal or the second audio signal, the step of determining that the person in the to-be-detected area has the call intention further includes:
step S410, when the audio amplitude in the to-be-detected area is determined to reach the preset audio amplitude according to the first audio signal or the second audio signal, judging that the person in the to-be-detected area has the conversation intention, and starting a horn module;
the step of calculating a time difference between the acquired first audio signal and the acquired second audio signal, adjusting audio parameters of the first audio signal and the second audio signal according to the time difference so that the audio parameters of the adjusted first audio signal are consistent with the audio parameters of the adjusted second audio signal, and generating audio information of the region to be measured by overlapping the adjusted first audio signal and the adjusted second audio signal specifically comprises:
and S360, when the fact that the person in the area to be detected has the conversation intention is determined, calculating and acquiring the time difference between the first audio signal and the second audio signal, adjusting the audio parameters of the first audio signal and the second audio signal to enable the adjusted audio parameters of the first audio signal to be consistent with the adjusted audio parameters of the second audio signal, superposing the adjusted first audio signal and the adjusted second audio signal to generate the audio information of the area to be detected, and outputting the audio information of the area to be detected to the loudspeaker module to be played.
In this embodiment, if the controller confirms that the audio amplitude in waiting to detect the region reaches when predetermineeing audio amplitude according to signal or second audio signal, can think that the personnel in waiting to detect the region have the intention of speaking, just can control loudspeaker module and open, just will generate wait to detect audio information output to loudspeaker module broadcast to realize the user and wait that the personnel in the detection region converse.
In another embodiment, referring to fig. 8, when it is determined that the audio amplitude in the to-be-detected region does not reach the preset audio amplitude according to the first audio signal or the second audio signal, the step of determining that the person in the to-be-detected region does not have the intention of talking further includes:
step S510, when it is determined that the audio amplitude in the detection area does not reach the preset audio amplitude according to the first audio signal or the second audio signal, it is determined that the person in the detection area does not have the intention of calling, and the loudspeaker module is controlled to stop working.
In this embodiment, if the controller determines that the person in the area to be detected does not have the speaking intention, the horn module is not started, so that the power consumption of the intelligent security equipment is effectively reduced.
Optionally, in another embodiment, with reference to the above embodiment, if the controller finds that, according to the person movement information, when the person in the detection area has no intention to talk, that is, the mouth movement is not a speaking movement, it may also control the speaker module to stop working at the same time. Therefore, when someone enters the to-be-detected area, if the person does not have the conversation intention, the intelligent security equipment cannot start to work with related components in the conversation system, and the power consumption of the intelligent security equipment is further reduced.
Whether the behavior of the personnel in the current region to be detected meets the mouth speaking action and the intensity of the speaking sound reaches the decibel of the preset amplitude representation or not is judged, the accuracy of judging whether the personnel have the conversation requirement or not by the intelligent security equipment can be effectively improved, the working reliability and stability of the intelligent security equipment are further ensured, and the situation that the power consumption is increased due to the fact that the intelligent security equipment is started by mistake by misjudgment is prevented.
