Description

Presence detection device, presence detection control apparatus, and presence detection method

Technical Field

The present invention relates to the field of presence detection, and more particularly to a presence detection apparatus, a presence detection control device, and a presence detection method.

Background

With the development of the internet of things technology, the requirements of artificial intelligence, smart home and intelligent security technology on environment detection, particularly on the detection accuracy of the existence or non-existence of a human body and the behavior state of the human body in the existing state are higher and higher, and only if a detection result which is accurate enough is obtained, an accurate judgment basis can be provided for the intelligent terminal device. The existing technologies for detecting and sensing human bodies mainly comprise: 1. the human body and the human body behavior state are identified by corresponding algorithms based on image acquisition, but the method is difficult to accept due to the risk of invading and leaking privacy, and has the defects of complex algorithm and high requirement on hardware performance, so that the method has higher cost. 2. The method comprises the steps that a Fresnel lens is used for partitioning a corresponding detection area, the trans-regional action of a human body in the detection area is detected through an infrared pyroelectric sensor (PIR), but the method is limited in that the partition precision of the Fresnel lens on the detection area cannot detect human body activity corresponding to human body respiration or heartbeat action, so that misjudgment is easily generated on the existence of the human body, and if the human body exists in the detection area in a static state, the human body is judged not to exist in the detection area, so that abnormal work of corresponding electric equipment controlled based on the detection result of the existence of the human body is caused. 3. The microwave detection technology based on the doppler effect principle specifically includes transmitting a microwave beam and receiving a reflected echo formed by the microwave beam reflected by a corresponding object, and generating a doppler intermediate frequency signal corresponding to a frequency difference between the microwave beam and the reflected echo in a mixing detection manner, where the doppler intermediate frequency signal is a feedback of a motion of the corresponding object. The microwave detection technology based on the Doppler effect principle is used as a person and an object, and an important junction connected between the object and the object has unique advantages in behavior detection and existence detection technology, can detect moving objects such as action characteristics, movement characteristics and micro-movement characteristics of the person and even heartbeat and respiration characteristic information of the person under the condition of not invading the privacy of the person, and has wide application prospect.

However, in order to obtain a sufficiently accurate detection result, specifically based on the detection result of the presence or absence of the heartbeat and/or respiratory action of the human body, to achieve accurate detection of the presence or absence of the human body, so as to still obtain a sufficiently accurate detection result in a static behavior state of the human body, such as a behavior state of sitting still or sleeping on the stomach, the existing microwave detection device based on the doppler effect principle has a requirement on the duration of the transmission of the microwave in the order of seconds or has a requirement on a duty ratio greater than 10%, and accordingly the existing microwave detection device is caused to operate in a mode of continuously transmitting the microwave or operate in a mode of intermittently transmitting the microwave with a pulse operation time in the order of seconds or greater than 10% of the duty ratio, and accordingly the operating current of the microwave detection device is 10 to 50mA and cannot be adapted to the power supply of the battery, specifically, taking the battery with a capacity of 2000mAh as an example for supplying power to the microwave, when the operating current of the microwave detection device is 25mA, the microwave detection device needs to be charged or replaced when operating for at most 80 hours, and the microwave detection device is mostly fixedly installed on the ceiling in a vertical detection manner, that is, the charging frequency or the battery replacement frequency of 80 hours/time is too frequent and impractical, so the existing microwave detection devices are designed to be connected into the power grid through corresponding lines in a power grid supply manner.

The microwave detection device adopts a wired networking mode, so that the wiring is complex, on one hand, the installation cost is high, such as the wire rod cost, the wire rod wiring cost, especially the hidden wire rod wiring cost of the wire rod, and is far higher than the cost of the microwave detection device per se in practice, on the other hand, the complex wiring is not beneficial to maintenance and repair and causes the substantial increase of the maintenance and repair cost, namely, the popularization of the microwave detection device is mainly limited by the installation and maintenance and repair cost of the microwave detection device. Therefore, the implementation of the wireless networking of the microwave detection device by the battery power supply is beneficial to simplify the installation and maintenance of the microwave detection device and reduce the installation and maintenance cost of the microwave detection device, thereby being beneficial to the popularization of the microwave detection device, and as mentioned above, in order to obtain a sufficiently stable detection result, the power consumption of the existing microwave detection device is difficult to reduce, for example, in the chinese invention publication with application publication No. CN111867025A, a low power consumption microwave sensor and a control circuit thereof are disclosed, which are used for providing periodic pulse operation to a low noise amplifier, a mixer, a radio frequency oscillator, a power amplifier and a low frequency filter amplifier respectively through a power management module, and the pulse operation time TON is several microseconds, the pulse operation gap TOFF is several milliseconds, and the corresponding duty ratio is far lower than 1% and is only suitable for the movement detection of a human body, that is, a wireless network system for implementing the microwave detection device by battery power supply has a great commercial value, but the current microwave detection device has difficulty in simultaneously considering the stability of detection results and low power consumption, and accordingly, the microwave detection device is impractical to frequently charge or replace batteries in a battery power supply state.

In addition, the chinese utility model publication with the authorized bulletin number of CN204632030U discloses an infrared microwave dual-technology detector, which only senses signals when an infrared detection circuit senses signals and restarts a microwave emission and detection function to save power by combining the infrared detection with the microwave detection, and alarms when infrared and microwave simultaneously detect signals, i.e. it limits the application scene to an environment of "no human exists in most cases" based on alarm application, i.e. for environments with long human body stay time or frequent human body movement, such as bedrooms, office places, public places, etc., based on "only senses signals when an infrared detection circuit senses signals and restarts a microwave emission and detection function" to cause frequent microwave emission and unable to save power, and the scheme based on "infrared and microwave simultaneously detect signals and then alarm" cannot adapt to human body in a static state or intermittent static state The scenario in which the state exists.

In addition, the penetration characteristic of the microwave is used as a unique advantage of microwave detection, and adverse effects may also be generated in a corresponding usage scenario, specifically, in a doppler intermediate frequency signal obtained based on the doppler effect principle, where the amplitude of the doppler intermediate frequency signal is directly related to the motion amplitude of a human body under the same distance limitation, where since the motion of the human body has a larger amplitude span and the amplitude of the corresponding doppler intermediate frequency signal has a larger amplitude span, the detection range of the motion of the human body cannot be accurately defined according to the corresponding threshold setting of the amplitude of the doppler intermediate frequency signal, that is, effective coverage of a target detection space is satisfied, a transmitted microwave beam has a coverage area beyond the target detection space based on the penetration characteristic and the reflection characteristic of the microwave, and human body motion interference in a non-target detection space cannot be, thereby affecting the accuracy of the detection of the presence or absence of a human body in the target detection space.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be constructed and operated in a particular orientation and thus are not to be considered limiting.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 of the drawings accompanying the present specification, the operating logic of a presence detection apparatus according to an embodiment of the present invention is illustrated, wherein the presence detection apparatus has a first detection mode in which the presence detection apparatus is capable of reducing power consumption requirements for the presence detection apparatus by obtaining a detection result of the presence or absence of a human body based on the detection of an activity presence characteristic corresponding to a movement of the human body, and a second detection mode in which the presence detection apparatus is capable of ensuring accurate detection of the presence or absence of a human body based on the detection result of the presence or absence of a human body based on the detection of a static presence characteristic corresponding to a heartbeat and/or a breathing movement of the human body.

Specifically, in view of the fact that the entering or leaving motion of the human body with respect to the corresponding detection zone necessarily forms the moving motion of the human body, after the presence detection means detects the presence of the active presence feature of the detection zone based on the first detection mode until the detection zone does not have the active presence feature for a continuous time period of t1, the human body entering the detection zone is in a static presence state or a state of leaving the detection zone, the presence detection means activates the second detection mode only at least once after the presence of the active presence feature of the detection zone based on the first detection mode until the detection zone does not have the active presence feature for a continuous time period of t1, then in the second detection mode, the detection result of the presence of the static presence feature of the detection zone corresponds to the presence state of the human body entering the detection zone, and the detection region is in a state of leaving the detection region corresponding to the detection result of the static existence characteristic, so that the average power consumption of the existence detection device is reduced and the accuracy of the detection result of the existence detection device is ensured.

That is, the presence detecting means operates in the first detection mode after being powered on, in which the corresponding human body enters the detection zone in an active state when the presence detecting means detects that the detection zone has the active presence feature based on the first detection mode, and subsequently, when the presence detecting means detects that the detection zone does not have the active presence feature for a continuous period of t1 based on the first detection mode, the presence detecting means corresponds to the detection of the presence of the static presence feature in the detection zone in a static state corresponding to the presence of the human body in the detection zone based on the second detection mode, and corresponds to the human body entering the detection zone in a state of leaving the detection zone based on the detection of the absence of the static presence feature in the detection zone.

Specifically, the presence detecting device includes a processor module, wherein the processor module triggers the timing of the duration t1 by the processor module after the presence detecting device acquires the detection result of the presence of the active presence feature in the detection region based on the first detection mode, and triggers the timing of the duration t1 by the processor module based on the duration t1 formed based on the detection result of the presence of the active presence feature in the detection region within the duration t1 (including but not limited to resetting the timing of the duration t1 with the current time node as the timing start and re-timing the duration t1 with the time node after the duration t1 as the timing start), and after the timing of the duration t1 by the processor module ends (corresponding to the situation that the duration t1 by the duration t1 formed based on the detection result of the absence of the active presence feature in the detection region), the second detection mode is activated at least once under the control of the processor module, namely, the second detection mode is activated only in the case that all the human bodies entering the detection area leave the detection area and in the case that all the human bodies entering the detection area keep static for a time longer than t1, so that the activation scenario of the second detection mode is limited for general indoor use scenarios, such as offices, meeting rooms, bedrooms and the like, so as to reduce the average power consumption of the presence detection device and guarantee the accuracy of the detection result of the presence detection device.

Further, in the first detection mode, the presence detection device detects the cross-zone action of the human body in the detection area by an infrared pyroelectric sensor (PIR) based on the zone division of the detection area by a fresnel lens, or detects the human body activity in the detection area by microwaves with pulse working time in the microsecond order and duty ratio lower than 1% based on the doppler effect principle, so as to obtain the detection result of whether the activity presence feature exists in the detection area based on the corresponding threshold setting, and can realize a low power consumption state that the presence detection device has the working current lower than 1mA in the first detection mode; in the second detection mode, the presence detection device detects human body activities including human heartbeat and/or respiratory actions in the detection region based on the Doppler effect principle by continuously emitting microwaves or microwaves with pulse working time as the second level or duty ratio larger than 10% so as to obtain a detection result of whether the detection region has static presence characteristics or not by setting corresponding threshold values, thereby ensuring accurate detection of the presence or absence of the human body.

Referring to fig. 2 to 3B of the drawings of the present specification, a block diagram of the structure and the operation logic of the presence detection apparatus according to an optimized embodiment of the above-mentioned embodiment of the present invention are respectively illustrated, wherein in this optimized embodiment of the present invention, in the first detection mode, the presence detection apparatus detects the trans-regional action of the human body in the detection region by an infrared pyroelectric sensor (PIR) based on the fresnel lens for the partition of the detection region with the first detection module 20, so as to obtain the detection result of whether the activity presence feature exists in the detection region based on the corresponding threshold setting, and can realize the low power consumption state of the presence detection apparatus having the operation current lower than 1mA in the first detection mode, wherein based on the partition of the detection region by the fresnel lens, the detection range of the activity presence feature by the presence detection apparatus can be accurately controlled to avoid the activity outside the fresnel detection region The interference of the dynamic presence characteristic correspondingly improves the stability of the presence detection device.

In the second detection mode, the presence detection apparatus detects static presence features corresponding to human heartbeat and/or respiratory motion by microwaves with a second detection module 30 based on the doppler effect principle, and preferably detects static presence features corresponding to human heartbeat and/or respiratory motion by microwaves with pulse duty time of second or more than 10% duty cycle, so as to reduce power consumption of the second detection module 30 while ensuring detection accuracy of the static presence features corresponding to human heartbeat and/or respiratory motion.

In particular, with reference to fig. 3B, in the second detection mode, the detection of the static presence features corresponding to the heartbeat and/or respiratory actions of the human body by the presence detection means with microwaves based on the doppler effect principle comprises the following steps:

(a) transmitting at least one microwave beam corresponding to an excitation signal frequency;

(b) receiving a reflected echo formed by the microwave beam reflected by a corresponding object to generate a corresponding echo signal;

(c) generating a Doppler intermediate frequency signal based on the frequency/phase difference between the excitation signal and the echo signal by means of mixed detection;

(d) converting the Doppler intermediate frequency signal into a fluctuation signal based on the change of the frequency/amplitude of the Doppler intermediate frequency signal along with time, namely converting the fluctuation signal into a change signal of the frequency/amplitude of the Doppler intermediate frequency signal along with time; and

(e) the undulation signal of a particular frequency range in the undulation signal is selected in a filtered manner, wherein the particular frequency range lies within a frequency range smaller than 50Hz, i.e. the set of particular frequency ranges is a subset of the set of frequency ranges smaller than 50 Hz.

It is to be understood that, in the step (c), the frequency of the doppler intermediate frequency signal corresponds to the movement velocity of the corresponding object, the amplitude of the doppler intermediate frequency signal corresponds to a range of amplitude of the movement of the corresponding object to some extent and also corresponds to the movement velocity of the corresponding object, so that when the step (d) converts the doppler intermediate frequency signal into the fluctuation signal based on the change of the frequency/amplitude of the doppler intermediate frequency signal with time, the fluctuation of the amplitude of the fluctuation signal corresponds to the fluctuation of the movement velocity of the corresponding object with time, and when the corresponding object is a human body and the fluctuation signal represents human body motion, one fluctuation of the amplitude of the fluctuation signal corresponds to one motion in which the relative velocity tends to zero from beginning to end of the human body, such as one thoracic cavity expansion motion caused by human body inhalation motion, that is, the fluctuation frequency of the fluctuation signal corresponds to the frequency of the corresponding action, so that in the step (e), since the specific frequency range is in the frequency range less than 50Hz and is in the electromagnetic silence frequency, the fluctuation signal corresponding to the specific frequency range is a very low frequency signal, the high-magnification amplification of the fluctuation signal of the specific frequency range does not affect the accuracy of the fluctuation signal of the specific frequency range, and the corresponding fluctuation in the fluctuation signal corresponding to the human body static existence feature of the specific frequency range is allowed to be identified by means of the high-magnification amplification, thereby realizing the detection of the static existence feature corresponding to the human body heartbeat and/or respiratory action by microwaves.

It is worth mentioning that, in which the amplitudes of the respective wave signals are directly related to the amplitude of the movement of the person under the same distance limitation, wherein the respective threshold settings for the amplitude of the wave signals mainly correspond to the definition of the detection distance for the static presence feature due to the narrower amplitude span of the heartbeat and/or respiration movement of the person and the narrower amplitude span of the corresponding amplitude for the amplitude of the wave signals, and the attenuation of the microwaves due to the penetration behavior and the reflection behavior of the microwaves based on the penetration characteristic and the reflection characteristic is equivalent to a reduction in the detection distance, i.e. the static presence feature of the non-target detection space that is propagated based on the penetration characteristic and the reflection characteristic of the microwaves has a relatively low wave amplitude in the wave signals, thereby allowing the shielding based on the respective threshold settings for the amplitude of the wave signals, so that the microwave detection device can detect the static presence feature based on the wave signals of extremely low frequencies The interference of the static existence characteristics of the non-target detection space, such as the interference of the static existence characteristics of the non-target detection space based on the penetration characteristic and the reflection characteristic of the microwave through-wall diffusion and the reflection/diffusion, is accurately defined according to the corresponding threshold setting.

That is, in the preferred embodiment of the present invention, in which the presence detection means detects the active presence feature with an infrared pyroelectric sensor (PIR) based on a fresnel lens for the partition of the detection area in the first detection mode and detects the static presence feature with microwaves based on the doppler effect principle in the second detection mode, the disadvantages that the state in which the static presence feature is not detected in the first detection mode and thus the presence or absence of a human body is easily misjudged are avoided, and the problem that the detection range in detecting the active presence feature with microwaves based on the doppler effect principle is not accurately controlled and is easily interfered by the active presence feature outside the detection area is avoided, and the detection range of the presence detection means can be accurately controlled, while the average power consumption of the presence detection means can be reduced based on the activation rule of the second detection mode, and can realize the accurate detection of the existence of the human body and the state of the human body in the detection area, and allow the behavior state of the human body in the detection area to be simultaneously judged according to the detection of the human body activity existence characteristic and the static existence characteristic based on the corresponding judgment rule.

It is understood that the narrower the specific frequency range, the lower the ambient motion with motion frequency in the specific frequency range, the lower the interference probability of the corresponding ambient motion on the fluctuation signal, therefore, to further improve the correlation degree of the fluctuation signal of the specific frequency range and the human heartbeat and/or respiratory micro-motion, so as to ensure the accuracy of the feedback of the vital signs corresponding to the human heartbeat and/or respiratory micro-motion by the fluctuation signal of the specific frequency range, the specific frequency range is preferably set in a very low frequency range less than 1Hz, wherein since the frequency of the human respiratory motion is generally less than or equal to 1Hz, i.e. the number of respiratory motions per second is less than 1, and the fluctuation frequency corresponding to the human respiratory motion in the fluctuation signal is less than or equal to 1Hz, by setting the specific frequency range in a very low frequency range less than or equal to 1Hz, the specific frequency range is narrowed, wherein the interference probability of the corresponding environmental action on the fluctuation signal is reduced because the environmental action with the action frequency less than or equal to 1Hz is less, the association degree of the fluctuation signal and the human respiration micro action in the specific frequency range is improved, and the amplitude of the fluctuation signal in the specific frequency range is ensured because the action amplitude of the human respiration micro action is far higher than the action amplitude of the human heartbeat action, so that the association degree of the fluctuation signal and the human respiration micro action in the specific frequency range is improved, and the strength of the fluctuation signal is ensured, thereby being beneficial to improving the accuracy of the feedback of the fluctuation signal in the specific frequency range on the vital signs corresponding to the human respiration micro action.

In particular, to further reduce the average power consumption of the presence detection means while ensuring the accuracy of the detection of the presence or absence of a human body by the presence detection means, with reference to fig. 3A, in this preferred embodiment of the invention, wherein the timing of the duration of t2 by the processor module 10 is triggered after the timing of the duration of t1 (corresponding to the detection result of the absence of the active presence feature of the detection region during the duration of t1 not forming a continuation condition of the duration of t 1), wherein the second detection mode is activated at least once during the duration of t2 under the control of the processor module 10 and is deactivated after the timing of the duration of t2 or is deactivated during the duration of t2 based on the detection result of the presence of the static presence feature of the detection region, so as to reduce the average power consumption of the presence detection means and achieve the accuracy of the presence or absence of a human body based on this cyclical operating logic, and simultaneously, the behavior state of the human body in the detection area is allowed to be simultaneously judged according to the detection of the human body activity presence characteristic and the static presence characteristic based on the corresponding judgment rule.

Further, in a state where the second detection mode is turned on, the first detection mode is maintained to be turned on, and the second detection mode is turned off when the presence detection apparatus returns the timing of the time duration t1 after acquiring the detection result of the detection zone with the active presence feature based on the first detection mode, and preferably ends the timing of the time duration t2, that is, in the cyclic working logic of the presence detection apparatus, the detection result of the detection zone with the active presence feature has a higher priority than the detection result of the detection zone with the static presence feature, corresponding to any time duration, and the timing of the time duration t1 is returned after acquiring the detection result of the detection zone with the active presence feature based on the first detection mode, so as to avoid that the behavior state of the human body in the detection zone leaving the detection zone during the timing of the time duration t2 is misjudged as that the detection zone is in a static presence state The state exists, so that the accuracy of the detection result of the presence detection device is guaranteed, and the average power consumption of the presence detection device can be further reduced.

Specifically, in a state that the presence detection apparatus is connected to a power supply, the processor module 10 is electrically connected to a corresponding power supply, such as a battery or commercial power, the first detection module 20 is communicatively connected to the processor module 10 and is electrically connected to the power supply, such as being electrically connected to the power supply in a state of being directly electrically connected to the power supply, or being electrically connected to the power supply in a state of being electrically powered by the power supply via the processor module 10, wherein the second detection module 30 is communicatively connected to the processor module 10 and is electrically powered to the power supply under the control of the processor module 10, and the switch 11 is exemplarily provided between the second detection module 30 and the power supply in a state of being controlled by the on-off of a switch 11, such as but not limited to an electric control switch, a relay, a triode, a MOS transistor, a silicon controlled thyristor, and the like, wherein the switch 11 is electrically connected to the processor module 10 and is controlled by the processor module 10 to be switched on and off.

That is, the presence detection apparatus operates in the first detection mode after being powered on, wherein when the processor module 10 acquires a detection result of the presence of activity of the detection zone by the first detection module 20 based on the corresponding threshold setting, the processor module 10 triggers timing of a time period t1 and judges that the human body enters (exists) the detection zone in an active state, wherein within the time period t1, the processor module 10 forms a continuation condition for a time period t1 based on the detection result of the presence of activity of the detection zone and continues the timing of a time period t1 and judges that the human body exists in the active state in the detection zone, and subsequently, when the processor module 10 acquires a detection result of the presence of activity of the detection zone by the first detection module 20 based on the corresponding threshold setting for the absence of activity of the detection zone within a continuous time period t1, the processor module 10 triggers timing of a time duration of t2 and controls the second detection module 30 to start at least once within a time duration of t2, wherein the processor module 10 determines, based on corresponding threshold settings, that the human body is present in the detection zone in a static state when the second detection module 30 acquires the detection result of the detection zone that the static presence feature is present, determines, based on the detection result of the detection zone that the static presence feature is not present, that the human body entering the detection zone is in a state of leaving the detection zone, and controls the second detection module 30 to turn off after the timing of the time duration of t2 is finished, or controls the second detection module 30 to turn off within a time duration of t2 based on the detection result of the detection zone that the static presence feature is present.

It is worth mentioning that, in the second detection mode, when the processor module 10 acquires the detection result of the presence of the static presence feature of the detection region by the second detection module 30 based on the corresponding threshold setting, it is determined that the human body is present in the detection region in a static state, and after the timing of the time period t2 is ended, the second detection module 30 is controlled to be turned off, or the second detection module 30 is controlled to be turned off within the time period t2 based on the detection result of the presence of the human body in the detection region, and subsequently, when the processor module 10 acquires the detection result of the presence of the activity feature of the detection region by the first detection module 20 based on the corresponding threshold setting, it is determined that the human body is changed from the static state to the active state and is present in the detection region, so as to implement the detection of the human body to the presence feature of the activity and the static presence feature of the human body based on the corresponding determination rule under the above-mentioned cyclic working The determination of the behavior state of the detection region includes, for example, entering (existing) the behavior state of the detection region in an active state, existing the behavior state of the detection region in a static state, changing from the static state to the activity state, existing the behavior state of the detection region, and leaving the behavior state of the detection region.

It can be understood that, when the first detection module 20 detects the cross-zone action of the human body in the detection area by using an infrared pyroelectric sensor (PIR) based on the partition of the detection area by the fresnel lens, the higher the accuracy of the first detection module 20 configured as the infrared pyroelectric sensor (PIR), the higher the trigger frequency of the processor module 10 for the time duration t2 can be reduced, thereby being beneficial to reducing the average power consumption of the presence detection device, whereas the existing infrared pyroelectric sensor (PIR) has a lower operating current, generally 30uA to 50uA, but the detection accuracy thereof cannot meet the human body presence detection in a static state, and the present invention starts and stops the second detection mode according to the above cyclic operating logic, while ensuring the stability of the detection result of the presence detection device, the average power consumption of the presence detection means can be reduced.

That is, the presence detecting apparatus detects the active presence feature by an infrared pyroelectric sensor (PIR) based on a fresnel lens for a partition of the detection region in the first detection mode and detects the static presence feature by microwaves based on the doppler effect principle in the second detection mode, which avoids both the defect that the state of the presence or absence of a human body is easily misjudged due to the failure to detect the static presence feature in the first detection mode and the problem that the detection range is not accurately controlled and is easily interfered by the active presence feature outside the detection region when the active presence feature is detected by microwaves based on the doppler effect principle, and the detection range of the presence detecting apparatus can be accurately controlled based on the activation and deactivation of the second detection mode according to the above-described cyclic operation logic, and the average power consumption of the presence detecting apparatus can be reduced, and can realize the accurate detection of the existence of the human body and the state of the human body in the detection area, and allow the behavior state of the human body in the detection area to be simultaneously judged according to the detection of the human body activity existence characteristic and the static existence characteristic based on the corresponding judgment rule.

Optionally, in some embodiments of the present invention, wherein in the second detection mode, the processor module 10 shunts the second detection module 30 for detecting activity presence features corresponding to human body movement actions and static presence features corresponding to human body heartbeat and/or respiratory actions based on respective threshold settings, wherein in a state in which the second detection mode is turned on, the first detection mode is turned off to reduce the average power consumption of the presence detection apparatus, and the processor module 10 turns off the second detection mode by triggering the timing of the time period of t1 and preferably ending the timing of the time period of t2 after the second detection module 30 acquires detection results of the detection zone presence activity presence features in accordance with human body activities corresponding to human body movement actions based on respective threshold settings, so as to avoid that the behavior state of the human body in the detection area leaving the detection area during the timing process of the time length t2 is misjudged as the presence state of the detection area in a static state, and further reduce the average power consumption of the presence detection device, thereby ensuring the stability of the detection result of the presence detection device.

Further, in this preferred embodiment of the invention, the timing of the duration of t2 by the processor module 10 is optionally time-delayed, i.e., after the processor module 10 times the duration of t1, the delay triggers the timing of the duration of t2, so as to avoid frequent triggering of the timing of the time duration t2 by the transient static state and frequent in and out behavior of the human body in the detection area through the delayed triggering of the timing of the time duration t2, i.e., during a time delay, when the processor module 10 triggers the timing of the duration t1 after the acquisition of the detection result of the presence of activity characteristic of the detection zone by the first detection module 20 based on the corresponding threshold setting, the average power consumption of the presence detection means is further reduced by correspondingly avoiding frequent triggering of the second detection mode, and can keep t1 for a suitable length of time to ensure timely feedback of the human behavior state by the presence detection apparatus based on the first detection mode.

It is worth mentioning that the presence detection apparatus triggers the timing of the time duration t2, that is, the second detection mode is only activated during the time duration t2 when the processor module 10 sets the first detection module 20 to obtain the detection result that the activity presence feature exists in the detection region from the detection result that the activity presence feature does not exist in the detection region within the continuous time duration t1, that is, only when the human body entering the detection region completely leaves the detection region and when the human body entering the detection region completely remains static for a time duration exceeding t1, so that the setting of the time duration t1 is advantageous to avoid frequent triggering of the timing of the time duration t2 and is advantageous to reduce the average power consumption of the presence detection apparatus, whereas the setting of the time duration t1 which is too long is disadvantageous to the presence detection apparatus to feed back the activity state of the human body in time based on the first detection mode and cannot be based on human being unable to detect the activity state in time based on the first detection mode The body behavior state enables real-time control of the corresponding electrical device, and therefore, in this embodiment of the present invention, the time duration t1 is preferably set to be greater than or equal to 5 seconds, so as to facilitate reduction of frequent activation of the second detection mode and reduction of average power consumption of the presence detection apparatus while ensuring timely feedback of the body behavior state by the presence detection apparatus based on the first detection mode.

Further, in this embodiment of the present invention, the time period t2 is preferably set to be 1 minute or less to ensure the accuracy of the detection result of the presence detection apparatus for the presence or absence of a human body in the detection region in the second detection mode while reducing the average power consumption of the presence detection apparatus, and taking the case where the presence detection apparatus has an operating current of 100uA in the first detection mode and an operating current of 25mA in the second detection mode, when the time period t2 is set to a state of 10 seconds, even if the activation trigger for the second detection mode is triggered 60 times every 24 hours, the presence detection apparatus has an average operating current of 273uA, that is, further taking a battery with a capacity of 3000mAh as an example, in a state where the presence detection apparatus is powered by the battery, the presence detection apparatus can theoretically operate 457 days, thus accommodating battery power without requiring frequent charging or replacement of the battery.
