It is understood that the specific range of the area to be detected may be set by the developer, or may be set by the user according to the requirement.
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, the controller is electrically connected with the loudspeaker module, and when it is determined that a person enters the to-be-detected region, the behavior state of the person, such as the behavior states of "speaking voice, facial action, gesture action" and the like, can be detected and collected to generate corresponding behavior state information, and whether the person in the to-be-detected region needs to communicate with the user side of the intelligent security device or not is judged according to the behavior state information, namely whether the person in the to-be-detected region has an intention to communicate is judged. When the controller judges that the person in the current detection area to be detected has the speaking intention, the controller can control the current loudspeaker module to start working so as to meet the actual requirement of communication between the user and the person in the detection area to be detected.
It can be understood that, referring to fig. 6, in an embodiment of the present invention, the intelligent security control method further includes:
and S400, controlling the horn module to be in a stop state when determining that the personnel in the area to be detected do not have the intention of communication according to the behavior state information.
In this embodiment, if according to the behavior state information of personnel, for example, wait to detect the sound size that the personnel in the district spoken, perhaps wait the action of the mouth of the personnel in the district, confirm that the personnel in waiting the detection zone need not carry out the conversation at present, the controller in the intelligent security equipment just can not control loudspeaker module and open, just also can not make the amplifier circuit inside loudspeaker module begin to work, has reduced the consumption of intelligent security equipment effectively.
According to the technical scheme, whether a person enters the to-be-detected area is detected, the behavior state of the person in the to-be-detected area is collected when the person is determined to enter the to-be-detected area, corresponding behavior state information is generated, and the horn module is controlled to be started when the person in the to-be-detected area is determined to have the call intention according to the behavior state information. So, just can not open loudspeaker module the very first time earlier when confirming someone gets into and treats that the detection zone is interior, but when the personnel have the intention of speaking in the confirmation is treated the detection zone, control loudspeaker module again and open to when confirming that the personnel that treat the detection zone is interior do not speak the intention, control loudspeaker module and keep out of operation state, thereby reduced intelligent security equipment's consumption effectively.
Optionally, referring to fig. 3, in an embodiment of the present invention, the intelligent security device includes an image sensing component, and the step of acquiring the behavior state of the person in the area to be detected and generating corresponding behavior state information when it is determined that the 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 shooting image information of the person in the area to be detected;
step S230, performing action recognition on the image information to generate corresponding personnel action information;
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, waits to detect the image of the intraductal personnel of district, when confirming personnel's position, still can carry out action recognition, for example facial action recognition to image information, and generate corresponding personnel action information.
When determining that the personnel in the area to be detected has the intention of communication according to the behavior state information, the step of controlling the horn module to be opened specifically comprises the following steps:
and S310, controlling the loudspeaker module to start working when determining that the mouth movement of the person in the detection area is a speaking movement according to the person movement information.
In this embodiment, if the face image can be normally recognized according to the person action information, and when the mouth action of the person in the region to be detected is recognized as the speaking action, it is determined that the person in the current region to be detected has the intention of calling, and the speaker module is controlled to start working. For example, in a certain preset time, when the mouth opening ratio action times of the personnel in the area to be detected reach the preset times, the mouth action of the personnel in the current area to be detected is determined to be a speaking action, and the horn module is controlled to start working.
In addition, in another 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 speaker module to maintain the inactive state. Therefore, whether the personnel in the current detection area to be detected have the conversation intention can be judged through personnel action identification, and the horn module is controlled not to be started when the conversation intention is absent, so that the power consumption of the intelligent security equipment is reduced.
Optionally, referring to fig. 4, in an embodiment of the present invention, the intelligent security device includes a microphone, and the step of acquiring the behavior state of the person in the area to be detected and generating corresponding behavior state information when it is determined that the person enters the area to be detected includes:
step S240, when it is determined that a person enters the area to be detected, a microphone is started, the audio frequency in the area to be detected is obtained, and corresponding audio frequency information of the area to be detected is output;
when determining that the personnel in the area to be detected has the intention of communication according to the behavior state information, the step of controlling the horn module to be opened specifically comprises the following steps:
and step S320, controlling the loudspeaker module to start working when the audio amplitude of the area to be detected reaches the preset audio amplitude according to the audio information of the area to be detected.
In this embodiment, the controller is electrically connected with the microphone, the microphone can pick up the audio frequency in waiting to detect the district, and the audio signal who will pick up for analog signal carries out analog-to-digital conversion and then generates the district audio information that waits to detect that becomes digital signal, the controller can be according to waiting to detect the district audio information, confirm that the audio amplitude of waiting to detect the district currently, if audio amplitude has reached and has predetermine amplitude, for example, the sound intensity of predetermineeing the amplitude sign is 30 decibels, if the sound intensity that the audio amplitude sign is 40 decibels, then can confirm that the personnel that wait to detect the district currently have the conversation demand, just can open the loudspeaker module, in order to satisfy the user and wait to detect the conversation demand of personnel in the district.
In addition, in another embodiment, it can be understood that if the current audio amplitude does not reach the preset amplitude, it may be stated that the person currently in the detection area to be detected only speaks to another person, and does not have a requirement for communicating with the user side of the intelligent security device, and then the controller does not start the speaker module, so that the power consumption of the intelligent security device is reduced.
Optionally, referring to fig. 5, the intelligent security device includes a microphone and an image sensing component, and when it is determined that a person enters the region to be detected, the step of collecting the behavior state of the person in the region to be detected and generating corresponding behavior state information includes:
step S250, when a person is determined to enter the area to be detected, starting an image sensing assembly, and shooting image information of the person in the area to be detected;
step S260, performing action recognition on the image information to generate corresponding personnel action information, and controlling a microphone to be started to acquire audio in the area to be detected and output corresponding audio information of the area to be detected when determining mouth movement of personnel in the area to be detected as speaking action according to the personnel action information;
when determining that the personnel in the area to be detected has the intention of communication according to the behavior state information, the step of controlling the horn module to be opened specifically comprises the following steps:
and S330, controlling the loudspeaker module to start working when the audio amplitude of the detection area reaches the preset audio amplitude and the mouth movement of the person in the detection area is determined as a speaking action according to the audio information of the detection area.
In this embodiment, it can be understood that, in order to improve the accuracy of detecting whether the person in the area to be detected has the call intention, the scheme combining the two embodiments can be simultaneously adopted to detect the call intention of the person in the area to be detected.
In this embodiment, as can be seen from the above embodiment, when it is determined that a person enters the region to be detected, the controller may control the image sensing component, for example, the camera is turned on to capture image information of the person in the current region to be detected, and after performing motion recognition on the image information, generate corresponding person motion information, when it is determined that mouth motion of the person in the region to be detected is a speaking motion according to the person motion information, the controller may turn on the microphone again, and then determine whether the audio amplitude in the region to be detected reaches the preset amplitude according to the audio information in the region to be detected as in the above embodiment.
If the audio amplitude of the area to be detected reaches the preset audio amplitude and the mouth movement of the person in the area to be detected is used as a speaking action, controlling the loudspeaker module to start working so as to meet the conversation requirement of the person in the area to be detected and the user; if the audio amplitude of the to-be-detected area does not reach the preset audio amplitude, it is judged that the person in the to-be-detected area does not have the speaking intention, and therefore the loudspeaker module is controlled to keep a working stop state, and the power consumption of the intelligent security equipment is 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.
In addition, in another embodiment, if the current controller determines that the mouth movement of the person in the to-be-detected area is not a speaking movement according to the person movement information, that is, it determines that the person in the to-be-detected area does not have any speaking intention, the microphone is not turned on, so that the power consumption of the intelligent security device is further reduced.
Referring to fig. 2, in an embodiment of the present invention, the intelligent security device includes an infrared sensor, 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 method for determining that a person enters a detection area specifically comprises the following steps:
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.
It should be understood that, in the practical use of the intelligent security device, if someone else beside the user speaks or there is an environmental interference sound, the user cannot hear the speaking content of the person in front of the intelligent security device, which results in the degradation of the communication quality.
To this end, referring to fig. 7, in an embodiment of the present invention, the intelligent security device includes a complete machine and a driving component in driving connection with the complete machine, and a front microphone and a rear microphone in an end-fire array are disposed in the complete machine;
in the present embodiment, it should be understood that, referring to fig. 10 and 12, the front microphone and the rear microphone are in an end-fire array, that is, the front microphone and the rear microphone are arranged on the same straight line in the whole machine, the front microphone is arranged at the front end of the whole machine, and the rear microphone is arranged at the rear end of the whole machine. In practice, in order to improve the speech quality and reduce the effect of ambient noise, a two-microphone end-fire array may be used to form a beam-form, which forms a "difference" if the signal from the front microphone in the array is added to the inverted delayed signal from the rear microphone. If the sound comes from 0 degrees, the superposed sound is 2 times, namely the voice enhancement area, and the closer the angle of the sound comes from 0 degrees, the higher the audio amplitude of the audio information of the area to be detected generated by superposing the front and rear microphones finally and the smaller the noise in the audio information; if the sound comes from 90 deg., the superposition exactly cancels each other, i.e. the speech attenuation zone. Alternatively, the front microphone may be composed of a plurality of small microphones to form a front microphone array, and similarly, the rear microphone may be composed of a plurality of small microphones to form a rear microphone array.
When the execution determines that the personnel in the area to be detected has the intention of communication according to the behavior state information, the intelligent security control method further comprises the following steps of controlling the loudspeaker module to be opened:
s500, acquiring the position of a person in a region to be detected;
in this embodiment, intelligent security equipment still includes a personnel position detection subassembly that is used for detecting personnel's position, and personnel position detection subassembly is connected with the controller electricity, and after the controller confirmed that current personnel have got into to wait to detect the district, the controller can control personnel position detection subassembly and detect the personnel position of waiting in the detection district.
Optionally, the personnel position detection assembly may be implemented by a camera, and an image recognition chip may be integrated in the controller. The camera can be when personnel get into and treat in the detection zone, shoot the image of treating in the detection zone and generate corresponding image information to controller, the controller not only shows image information and uploads to external terminal such as user's cell-phone on the user side of intelligent security equipment or through the intercom subassembly, the controller can also treat the position of the personnel's image in the image of treating in the zone according to image information identification, thereby confirm the personnel's position of treating in the detection zone.
Optionally, the personnel position detection assembly can be realized by an ultrasonic positioning assembly or a microwave positioning assembly except that the camera for shooting the image in the area to be detected is directly adopted, the controller can start the ultrasonic positioning assembly after confirming that a person enters the area to be detected, and the ultrasonic positioning assembly can position the position of the area to be detected where the current personnel are located in an ultrasonic positioning mode.
And S600, controlling the driving assembly to drive the whole machine to move according to the position of the person in the area to be detected, so that the front microphone, the rear microphone and the person in the area to be detected are on the same straight line.
In this embodiment, as can be seen from the above, since the front microphone and the rear microphone form an end-fire array, the angle between the straight line where the front and rear microphones are located and the straight line where the person and the whole device are located is closer to 0 °, and the audio amplitude of the audio information of the region to be detected, which is finally output through the speaker module, is closer to 2 times of the amplitude of the sound signal emitted by the person to be detected, and is clearer.
