Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements throughout the different drawings, unless indicated otherwise. It should be understood that in the description of all embodiments of the invention, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a schematic structural diagram of a control system according to the present invention is shown, the control system is adapted to be disposed in a space to intelligently control environmental states (e.g. turning on, turning off, turning on an air conditioner, turning off the air conditioner, etc.) of the space, and as can be seen in fig. 1, the control system at least includes a detecting device 100 and a controlled device 200; the controlled device 200 is directly or indirectly operatively coupled to the probe device 100 to establish a communication connection therebetween; the detecting device 100 is configured to detect whether a person exists in the current space, and perform corresponding operations according to the detection result (e.g., determining that the current space exists, determining that the current space does not exist, determining that the current space maintains the time when the current space exists, determining that the current space exists far away, determining that the current space exists near, etc.), so that the controlled device 200 can perform intelligent linkage work on the detection result of the current space based on the detecting device 100 to perform intelligent adjustment of the space environment state.

It should be noted that "coupled" as referred to herein and hereinafter is to be understood in a broad sense, for example, may be electrically connected or may communicate with each other, or may be indirectly connected through an intermediate medium to form a linkage relationship, or may be a communication between two elements or an interaction relationship between two elements. Furthermore, any connection means capable of achieving an operable coupling relationship between the probe apparatus 100 and the controlled apparatus 200 can be used as an alternative of the present embodiment. In one example, the detection apparatus 100 and the controlled apparatus 200 are integrated into one device, thereby establishing an operable coupling relationship for direct electrical connection, such as through IIC, serial communication, etc. In another example, the probe device 100 and the controlled device 200 are separately configured and wirelessly connected by any wireless communication protocol, such as bluetooth communication protocol, WIFI communication protocol, ZIGBEE communication protocol, etc., to establish an operable coupling relationship. In another example, the probe device 100 and the controlled device 200 are separately provided and wired connected by wired communication means such as power carrier communication (PLC), KNX, etc. to establish an operable coupling relationship.

The controlled device 200 may be understood as any intelligent device capable of being controlled by a wireless control signal and/or a wired control signal to perform a related operation to change an operating state; which may be, for example, but is not limited to: lighting equipment, air conditioners, sound boxes, curtain partners, intelligent window pushers, intelligent wall switches and the like. The operations that can be performed by them can be, for example, but not limited to: is controlled to enter a certain working state; such as turning on or off a light, turning on or off an air conditioner, turning on or off a sound box, turning on or off a window shade, turning on or off a window, etc.

It will be appreciated that the specific type and executable functions of the controlled apparatus 200 may be arbitrarily changed based on the application field of the detection apparatus 100 or the change of the detection target, and should not depart from the scope of the embodiments of the present invention. For convenience of description, in most of the following embodiments, an illumination apparatus will be exemplarily set forth as the controlled device 200. It will be appreciated that the lighting device should at least have the function of turning on and off the lamp.

The space may be understood as an area associated with the environment of the space that the user wants to control, e.g. the user wants to operate the lighting device by means of the detection means 100, the space should be at least a partial area or an adjacent area within the coverage of the lighting device lighting area; the current space is understood to be at least a partial area in the whole space, and when the detecting device 100 detects that the current space is occupied, the lighting device can be linked to perform corresponding operation so as to change the lighting state of the area which the user wants to control.

It should be noted that fig. 1 is only an exemplary schematic diagram of a detection device 100 and a controlled device 200; however, in an actual control system, the number of the detecting devices 100 and the number of the controlled devices 200 may be plural, for example, the plurality of controlled devices 200 are controlled by one detecting device 100, or the plurality of controlled devices 200 are controlled by the detecting device 100, or one controlled device 200 is controlled by the plurality of detecting devices 100.

The detection device 100 may be understood as a component or combination of components adapted to be arranged in a space to identify whether the current space is a person or not based on detecting an action in the current space, which should be the whole space or at least a part of the space; as shown in fig. 2, the detection device 100 includes a processing module 102 and a detection module 101, where the detection module 101 is communicatively connected to the processing module 102, and the connection manner may be, for example, but not limited to, serial communication or IIC.

The processing module 102 should be understood as any component or combination of components that may implement the data analysis determination process. In a specific example, the processing module 102 may include a single chip microcomputer, a system on a chip (e.g. a bluetooth module, a WIFI module, a ZIGBEE module, etc.) integrated with an MCU and an RF, or a conversion circuit formed by separate components.

The detection module 101 is configured to obtain an action signal in the current space, and provide the action signal to the processing module 102, so that the processing module 102 determines whether a person is in the current space. The motion signal may be understood as any data that can be used to support the processing module 102 to analyze and determine whether a person is present in the current space.

In one example, the detection module 101 may perform preliminary processing after acquiring the motion signal, and obtain a motion signal representing whether a person exists in the space, and then send the motion signal to the processing module 102.

In another example, the detection module 101 may only acquire the original data of the motion signal in the space, send the data to the processing module 102, and the processing module 102 processes and analyzes the data according to a preset algorithm to determine whether a person is in the space.

As a further example, as shown in fig. 2, the detection module 101 may be a single-mode sensor having only a microwave-based radar module. The method comprises the steps of radiating detection microwaves (such as frequency modulation continuous waves) into a current space, receiving response echoes generated based on the detection microwaves, and analyzing the response echoes to obtain Doppler intermediate frequency signal data of frequency change, phase change and the like between the detection microwaves and the response echoes, wherein the Doppler intermediate frequency signal data can be transmitted to the processing module 102 as an action signal representing whether actions exist in the current space, and the processing module 102 analyzes the action signal to judge whether people exist in the current space.

In still another example, the detection device 100 may also be a dual-mode sensor including a microwave-based radar module and an infrared pyroelectric sensor based on infrared radiation; when the dual-mode sensor is adopted, the working principle of the radar module can still be understood by referring to the single-mode sensor, and the infrared pyroelectric sensor can be used as auxiliary detection to improve the detection precision of the human body.

It should be noted that, the detection apparatus 100 is further configured to implement a detection method, and further, the following description of the detection method may be understood as a description of a working process, a function, and a specific implementation of software and/or hardware of the detection apparatus 100, and an embodiment of a detection method corresponding to the detection apparatus 100 of the same embodiment will not be explained in detail herein, where effects, principles, functions, and the like of terms, features, and the like in the embodiment of the detection method may be understood with reference to descriptions of embodiments of the corresponding detection apparatus.

The inventor finds that the motion amplitude of a human body in different states is very different, for example, the motion amplitude of the human body is very large when the human body walks, the motion amplitude is very small when the human body sleeps (possibly only the respiratory floating of the thoracic cavity), but the existing detection device based on motion detection to identify whether the human body exists generally carries out the human body detection based on fixed sensitivity, so that the single sensitivity cannot be compatible with various motion amplitudes, the identification precision is not high, the application scene is single, and the complex and changeable use requirements cannot be met. Based on this, the detection device 100 provided in an embodiment of the present invention can adjust the sensitivity setting in a segmented manner, so that the user can implement a rich and varied detection sensitivity configuration through different setting modes of the sensitivity.

Specifically, in one embodiment of the present invention, the processing module 102 is configured to be capable of operating in:

a first recognition state to detect whether a person is present in the current space after determining that no person is present in the current space; and a second recognition state to detect whether the current space is occupied after determining that the current space is occupied;

It should be noted that, according to this embodiment, the processing module 102 acquires the motion signal of the current space through the detecting module 101 after starting the operation, and identifies that the current space is occupied when the motion signal exceeds the first identification threshold, and enters the second identification state to compare the acquired motion signal with the second identification threshold after confirming that the current space is occupied, identifies that the current space is unoccupied when the motion signal does not exceed the second identification threshold, and enters the first identification state again after determining that the current space is unoccupied to judge whether the current space is occupied based on the first identification threshold, so as to alternately realize whether the current space is occupied or not. It should be noted that the identification of the current spatial presence is not simply equivalent to the determination of the current spatial presence, and the identification of the current spatial presence may be understood that the processing module 102 determines that the primary motion signal exceeds the first recognition threshold or the second recognition threshold, and the determination of the current spatial presence may be understood that the processing module 102 determines that the at least one motion signal exceeds the first recognition threshold or the second recognition threshold. In other words, according to the solution provided in this embodiment, the processing module 102 will first enter the first recognition state to detect whether there is a person in the current space after starting the operation (after power-up), and trigger to enter the second recognition state after determining that there is a person in the space, to detect whether there is a person in the current space continuously (maintaining the presence of a person), and the first recognition state and the second recognition state are continuously and alternately performed. So that the processing module 102 can adaptively adjust the trigger someone's sensitivity at different stages before and after the target enters the current space to achieve different detection sensitivity requirements.

It will be further appreciated that the first recognition threshold is used by the processing module 102 to recognize whether the current space is occupied or not in the first recognition state, and that a change in the value of the first recognition threshold can cause a change in the sensitivity of triggering the occupied person in the first recognition state, that is, the greater the value of the first recognition threshold, the greater the magnitude of the motion required to recognize that the occupied person is occupied in the current space in the first recognition state (i.e., the lower the sensitivity), and the smaller the value of the first recognition threshold, the lesser the magnitude of the motion required to recognize that the occupied person is occupied in the current space in the first recognition state (i.e., the higher the sensitivity). Similarly, the second recognition threshold is used by the processing module 102 to recognize whether the current space is continuously occupied in the second recognition state, and a change in the value of the second recognition threshold can cause a change in the sensitivity of triggering the occupied in the second recognition state, that is, the greater the value of the second recognition threshold, the greater the magnitude of the action required to recognize that the occupied in the current space in the second recognition state (that is, the lower the sensitivity), and the smaller the value of the second recognition threshold, the lesser the magnitude of the action required to recognize that the occupied in the current space in the second recognition state (that is, the higher the sensitivity). And then the user can adjust the trigger sensitivity of first discernment state and second discernment state based on actual demand to improve the detection precision to the human body.

In an example, the detection device 100 is disposed in a living room, a bedroom, etc. and works in parallel with the lighting device, wherein the detection device 100 determines that the lighting device is turned on when the current space has people, and determines that the lighting device is turned off when the current space has no people; the first recognition threshold is set to be larger than the second recognition threshold, i.e. the first recognition state has a lower sensitivity and the second recognition state has a higher sensitivity. It can be understood that the motion amplitude of the person when the human body enters the current space is generally larger (such as walking or running), so that the first recognition state can avoid the small-amplitude motion (such as curtain jogging, fan interference, sound box vibration interference and the like) generated by the false recognition of the interference source through the higher first recognition threshold, and can also recognize the larger-amplitude motion generated when the human body enters the current space, thereby enhancing the anti-interference capability when the person is triggered and improving the accuracy of the person is triggered; when the human body is in the current space, the state of almost no movement or micro movement is likely to occur (for example, when sleeping or watching, only micro movement generated by breathing and heartbeat is likely to occur), and at the moment, if the difficulty of triggering someone is still relatively high, the small-amplitude movement of the human body can not be identified, so that when the condition that the current space is determined that someone enters the second identification state, the movement of the human body is identified by the lower second identification threshold value, and further, the movement of the human body only needs to generate smile amplitude can be identified, so that the sensitivity of the maintainer is improved, and the misjudgment probability is reduced. In other words, the processing module 102 will first enter the first recognition state after starting the operation (after power-up), detect whether there is a person in the current space with a higher first recognition threshold, trigger to enter the second recognition state and turn on the light after determining that there is a person in the space, and then detect whether there is a person in the current space continuously (maintain the person) with a lower second recognition threshold, enter the first recognition state when determining that there is no person in the current space, and turn off the light. The first recognition state and the second recognition state are continuously and alternately performed, so that the processing module 102 can adaptively adjust the sensitivity of the trigger person at different stages before the target enters the current space and after the target enters the current space, thereby realizing the accurate trigger person and maintaining the sensitive effect of the person.

In another example, the detecting device 100 is disposed in a space such as a corridor or a vestibule, and works in parallel with the lighting device, wherein the detecting device 100 determines that the lighting device is turned on when the current space has people, and determines that the lighting device is turned off when the current space has no people; the first recognition threshold is set smaller than the second recognition threshold, and therefore the first recognition state has higher sensitivity, and the second recognition state has lower sensitivity. It will be appreciated that the passage of a person through a corridor, vestibule or the like is generally transient, and therefore, the first recognition state, through a lower first recognition threshold, can quickly respond to lights to provide illumination when the person briefly passes through the current space, optimizing the user experience. The second recognition state can be switched to the recognition result of determining the unmanned person in time after triggering the unmanned person through the second higher recognition threshold value, so that the lamp is turned off in time in a linkage way after the short-term lamp is turned on for the user to illuminate, and the situation that the unmanned person cannot be recognized as the late person and the lamp cannot be turned off in a delay way after the person leaves is prevented from wasting electric energy due to curtain jogging, fan interference, loudspeaker box vibration interference and the like. In other words, the processing module 102 will first enter the first recognition state after starting the operation (after power-up), detect whether there is a person in the current space with a lower first recognition threshold, trigger to enter the second recognition state and turn on the light after determining that there is a person in the space, and then detect whether there is a person in the current space continuously (maintain the person) with a higher second recognition threshold, enter the first recognition state when determining that there is no person in the current space, and turn off the light. The first recognition state and the second recognition state are continuously and alternately performed, so that the processing module 102 can adaptively adjust the sensitivity of the trigger person at different stages before the target enters the current space and after the target enters the current space, so as to achieve the effects of fast response speed of the trigger person and high accuracy of the trigger person.

According to an embodiment of the present invention, the detecting device 100 further includes: a data acquisition module 103, configured to acquire spatial configuration data; the space configuration data is defined by interval L ₁ ～L _m Is generated after being freely selected; wherein L is ₁ ～L _m The 1 st to m th intervals of a space divided into m consecutive intervals are characterized, m being an integer greater than 1. The processing module 102 is further configured to: forming the current space based on the space configuration data; the current space is made up of all selected intervals. Furthermore, the detection device 100 can form a current space according to the plurality of intervals selected by the space configuration data, so that a user can freely select a target detection area covered by the current space based on actual requirements and configure the current space in a mode of issuing the space configuration data.

The data acquisition module 103 should be understood as any component or combination of components capable of implementing data transceiving. In particular examples, the data acquisition module 103 may be, for example, but not limited to, a WIFI communication unit, a bluetooth communication unit, or other radio frequency communication unit. Further, for example, the detection device 100 may establish a communication connection with a mobile terminal of a user through the data acquisition module 103, an application program (APP) corresponding to the detection device 100 is running on the mobile terminal, and the user freely selects L according to a target detection area detected by actual needs through a user operation interface of the APP ₁ ～L _m And further, issue relevant spatial configuration data to the detection device 100 to form the current space capable of covering a target detection area. Referring to FIG. 3, in one example, L ₁ ～L _m A section divided at 1m intervals from the space in the detecting device 6m, namely L ₁ The interval is [0m,1m ]]，L ₂ The interval is [1m,2m]，L ₃ The interval is 2m,3m]Of L of ₄ The interval is [3m,4m]，L ₅ The interval is 4m,5m]，L ₆ The interval is [5m,6m]. The user can arbitrarily select a desired target detection area (L is selected as in fig. 3) ₂ ～L ₄ Three intervals constitute the current space) to meet the actual demand.

In some embodiments, the processing module 102 is further configured to: and determining the section where the person is located as a trigger section, and sending trigger data representing the trigger section outwards so that an electronic device receives the trigger data and displays the section where the person is located. Furthermore, according to the scheme provided by this embodiment, when a person is triggered in a certain section, if the person is not actually triggered by an action generated by a human body (for example, the person is triggered by a drift of a curtain), the person is determined to be an interference source, and the user can reject the section where the interference source is located from the current space by looking at the display of the triggered section so as to quickly shield the interference source area, that is, the current space configuration data is generated after the user at least excludes the section where the interference source is located and then freely selects the section in the rest sections. In an example, a user can check the triggering condition of the current space in real time through an app user interface on a mobile phone, if a certain interval is found to be triggered but not the action generated by a human body, then the existence of an interference source in the triggering interval is judged, and the area where the interference source is located is accurately shielded by not selecting the triggering interval as a target detection area.

Further, the trigger data includes one shot data; and the one-time triggering data records a triggering interval where a person is when the person is switched to the unmanned one and/or the triggering interval where the person is when the person is switched to the unmanned one, so that the electronic equipment displays the historical triggering record of the space. In other words, when the processing module 102 determines that the current space is occupied by a person and when the current space is occupied by a person, the processing module performs the operation of reporting the one-shot data so that the user can view the one-shot data through the electronic device, and the user can locate the position of the triggered interference source (the interference source which is recovered to be normal after short triggering) according to the history of the one-shot data, thereby shielding the triggered interference source.

Further, the trigger data includes real-time trigger data; the real-time trigger data records the current states (whether someone exists or not) of all the intervals in the current space, so that the electronic equipment can display the real-time state of the current space, and a user can conveniently position the position of the continuous interference source according to the display of the real-time trigger data so as to carry out quick shielding. It will be appreciated that if one interferer is continuously present, the corresponding interval will continuously detect a person without switching to the unmanned state, so the interferer for that interval will be continuously present, such interferer being understood to be a persistent interferer. For the persistent interference source, the position of the interference source cannot be checked in a history record mode (because the history record is generally recorded in a record of switching from person to person or from person to person), so that the position of the persistent interference source can be rapidly positioned for shielding by triggering the display of data in real time.

In some embodiments, each interval L _i Correspondingly provided with a first sub-recognition threshold S _1i And a second sub-recognition threshold S _2i ；S _1i For defining an interval L in which the processing module 102 can recognize in the first recognition state _i The magnitude of the motion amplitude of the man; s is S _2i For defining an interval L in which the processing module 102 can recognize in the second recognition state _i The magnitude of the motion amplitude of the man; i epsilon [1, m]，S ₁₁ ～S _1m Composing the first recognition threshold S ₁ ，S ₂₁ ～S _2m Composing the second recognition threshold S ₂ . Wherein S is ₁₁ ～S _1m Respectively can be adjusted within a first specified threshold range, S ₂₁ ～S _2m Respectively, can be adjusted within a second specified threshold range, the first and second specified threshold ranges not being fully coincident, so that S can be adjusted ₁ And S is ₂ A greater range of sensitivity adjustments is achieved to cover more complex usage scenarios.

One specific judgment mode is described as follows:

the processing module 102 identifies whether a person exists in the current space if the action signal exceeds the first identification threshold value when identifying whether the person exists in the first identification state. Specifically, it can be understood that: if the action signal exceeds a first sub-recognition threshold corresponding to any section of the current space, judging that the action signal exceeds the first recognition threshold; otherwise, determining that the action signal does not exceed the first recognition threshold.

The processing module 102 identifies whether a person exists in the current space when the action signal exceeds the second identification threshold value in the second identification state. Specifically, it can be understood that: and if the action signal exceeds a second sub-recognition threshold corresponding to any section of the current space, judging that the action signal exceeds the second recognition threshold.

Further, the data acquisition module 103 is further configured to: acquiring threshold configuration data; the threshold configuration data is a threshold value of S on an electronic device by a user ₁₁ ～S _1m S and S ₂₁ ～S _2m Is generated after free definition; the processing module 102 is further configured to: based on threshold configuration data (definitionS at last ₁₁ ～S _1m ) A first recognition threshold S for determining a first recognition state ₁ A second recognition threshold S of a second recognition state ₂ 。

Furthermore, according to the present embodiment, the processing module 102 has a function of adjusting sensitivity in a partition, that is, by finely dividing the space, finer sensitivity setting can be achieved to adapt to a more complex usage space. In other words, the user can raise or lower the first sub-recognition threshold and/or the second sub-recognition threshold corresponding to any interval according to the spatial environment of the area actually required to be detected, that is, the triggering sensitivity (the lower the first sub-recognition threshold is, the higher the sensitivity is, the lower the sensitivity is), and the maintaining sensitivity (the lower the second sub-recognition threshold is, the higher the sensitivity is, the lower the sensitivity is) of each interval are reasonably set so as to realize the shielding effect of finer granularity, and the application requirements are more abundant.

Further, the processing module 102 is further configured to be capable of retaining the first sub-recognition threshold and the second sub-recognition threshold corresponding to the non-selected section, so that the user can quickly recover the previous setting in the later period. For example, the user sets the first section L for the first time ₁ Is the first sub-recognition threshold S of (2) ₁₁ Set to A, the second sub-recognition threshold S ₂₁ Set to B and shield L at the second setting ₁ When the user operates the mobile phone, L ₁ Corresponding S ₁₁ And S is ₂₁ Will be inoperable but can see S ₁₁ Is A, S ₂₁ B, and if the latter user wants to recover L ₁ Is easier to set up for the first time.

In some embodiments, the threshold configuration data is automatically generated by a user selecting one of a plurality of preset gear positions on an electronic device, so that the user can quickly switch to the corresponding sensitivity through the selection of the preset gear position according to the embodiment. In one example, the electronic device is preset with four gears of high sensitivity, medium sensitivity, low sensitivity and custom sensitivity, wherein three of the gears are high sensitivity, medium sensitivity and low sensitivityThe gear is preset with corresponding S ₁₁ ～S _1m S and S ₂₁ ～S _2m Threshold configuration data, the user can directly match preset threshold configuration data by selecting the corresponding gear, and the user can freely adjust S under the self-defined gear ₁₁ ～S _1m S and S ₂₁ ～S _2m To implement custom threshold configuration data. Based on the scheme, a user can conveniently and rapidly switch to the wanted sensitivity according to the selection of the high, medium and low gears, and personalized sensitivity configuration can be performed through the self-defined gears.

Further, when any one of the high-sensitivity, medium-sensitivity and low-sensitivity gear setting interfaces is detected, if the control of the first recognition threshold or the second recognition threshold for any one section is detected, the user is automatically switched to the self-defined sensitivity gear setting interface, and corresponding first recognition threshold and second recognition threshold data are synchronized to the self-defined sensitivity gear, so that a user can conveniently set the self-defined threshold on the basis of the preset thresholds of the high-sensitivity, medium-sensitivity and low-sensitivity gears, and the sensitivity is more convenient to adjust.

In a further example, when the sensitivity is set by selecting a gear, the threshold configuration data includes gear data and corresponding preset threshold data that are issued synchronously, so as to prevent the derangement of the gear and the threshold caused by network reasons (such as that one of the gear data or the preset threshold data issues an instruction to drop a packet or delay a longer time, etc.) when the two are issued separately.

Referring to fig. 4 to 6, a detection method according to the above embodiment of the present invention is specifically illustrated, as shown in fig. 4, the detection method at least includes step S1 and step S2, wherein:

s1, detecting whether a person exists in a current space;

s2, if no person is determined in the current space, detecting whether the current space is occupied or not in a first identification state; and if the person is determined to be in the current space, detecting whether the person is in the current space or not in a second identification state;

Referring to fig. 5, before detecting whether there is a person in the current space according to an embodiment of the present invention, further includes:

s0, acquiring space configuration data; the space configuration data is defined by interval L ₁ ～L _m Is generated after being freely selected; wherein L is ₁ ～L _m Characterizing a 1 st section to an m-th section of a space divided into m consecutive sections, m being an integer greater than 1;

Referring to fig. 6, the probing method further includes:

s3, determining the section where the person is located as a trigger section, and sending trigger data representing the trigger section outwards to enable electronic equipment to receive the trigger data and display the section where the person is located.

According to an embodiment of the invention, interval L _i The corresponding arrangement is:

first sub-recognition threshold S _1i Which characterizes the section L identifiable in the first identification state _i The magnitude of the motion amplitude of the middle person can be adjusted within a first appointed threshold range, and the lower the value is, the smaller the motion amplitude can be identified; and a second sub-recognition threshold S _2i Which characterizes a section L identifiable in a second identification state _i The magnitude of the motion amplitude of the middle person can be adjusted within a second specified threshold range, and the lower the value is, the smaller the motion amplitude can be identified;

According to an embodiment of the present invention, the detection method further includes:

determining S based on threshold configuration data ₁ And S is ₂ 。

In addition, in view of the problem that the existing detection device generally immediately performs state switching when a person is identified and is easy to cause false triggering, an embodiment of the present invention further provides a detection device 100 that does not immediately output a detection result after the person is identified, so as to be capable of shielding short-term interference.

Specifically, in one embodiment of the present invention, the processing module 102 is configured to be operable to: a first recognition state to detect whether a person is present in the current space after determining that no person is present in the current space; and a second recognition state to detect whether the current space is occupied after determining that the current space is occupied;

detecting whether a person exists in the current space in a first identification state, wherein the first identification state is specifically used for:

if the current space is identified as the existence of the person, detecting whether the current space exists or not in the first delay time; if yes, determining that people exist in the current space and entering a second identification state; otherwise, determining that the current space is unmanned, and maintaining the first identification state.

Further, in this way, the processing module 102 will not immediately determine that there is a person in the current space when it recognizes that there is a person, but continues to determine whether there is a person within the first delay time, so as to shield some short disturbances (such as mosquito flying, curtain being blown up instantaneously, etc.), so as to further improve the anti-interference capability.

According to an embodiment of the present invention, the processing module 102 is further configured to set the first delay time according to an instruction from an application program. Further, the first delay time may be freely set by the user according to the requirement, for example, when the detecting device 100 is set in a space such as a corridor or a vestibule, the effect that the human body passes through the current space briefly without triggering the controlled device 200 may be achieved by properly increasing the first delay time. For example, the controlled device 200 is a lighting device, when a person is detected in the current space, the light is turned on, when no person is detected in the current space, the light is turned off, when a person briefly passes through the current space, if the passing time does not exceed the first delay time, the person is not determined, and then the light is not turned on, thereby avoiding electric energy waste.

According to an embodiment of the present invention, the processing module 102 detects whether a person exists in the current space within a first delay time, which is specifically configured to: identifying whether the current space has a person or not at intervals for M times before the first time delay is finished by using the first time to identify that the current space has the start of the first time delay; if the M times of results are yes, determining that people exist in the current space; otherwise, determining that the current space is unmanned; wherein M is an integer greater than or equal to 1. Further, based on this embodiment, during the first delay time, the processing module 102 determines whether the current space is occupied by a person in a sampling manner at intervals, so as to prevent the aging speed of the processing module from being increased under the condition of sampling detection continuously, which results in the reduction of the whole service life of the product. And the instantaneous interference can be shielded to a certain extent by detecting M times at intervals, so that the anti-interference performance of the product is improved.

In one example, M takes 1, and the processing module 102 detects whether a person exists in the current space within the first delay time, which is specifically configured to: identifying whether a person is in the current space at the end of the first delay time; if yes, determining that the current space is occupied; otherwise, determining that the current space is unmanned. Furthermore, the processing module 102 starts the timing of the first delay time when the first identification state (i.e. the state of waiting for triggering the existence of the person when no person exists) and respectively identifies whether the person exists at the start point and the end point of the first delay time, when the start point and the end point of the first delay time respectively detect the existence of the person, the conclusion that the person exists in the current space is determined, and then the processing module 102 enters the second identification state (maintains the state of waiting for triggering the existence of the person) and does not detect the person between the start point and the end point, so as to further slow down the aging and reduce the power consumption.

According to an embodiment of the present invention, as shown in fig. 2, the detection module 101 of the detection device 100 directly adopts a radar module, that is, the detection device 100 further includes a radar module, and the radar module is electrically connected to the processing module 102; the processing module 102 detects whether the current space is occupied, specifically: acquiring an action signal of a current space through a radar module; the radar module sends the action signal to the processing module 102, and the processing module 102 analyzes the action signal to identify whether a person exists in the current space; the interval time of the radar module for transmitting the action signal changes randomly, so that the anti-interference performance is improved by introducing natural random numbers. For example, the interval time varies randomly within 60ms-100 ms.

Based on the scheme provided by the embodiment, the time of the action signal sent to the processing module 102 by the radar module is not fixed, so that the overall anti-interference capability is improved in a random manner, and the task of introducing the random number is completed by the radar module, so that the pressure of the processing module 102 is relieved to a certain extent, namely, the load of the processing module 102 is relieved while the anti-interference capability is improved.

Furthermore, according to the embodiment of the present invention, the probe apparatus 100 has a networking function, and thus the probe apparatus 100 can implement network connection with a controlled apparatus connected to the same network (for example, the network where the same server is located) for data interaction and control. The user can customize a plurality of control rules by the mobile phone to be pre-stored in the server, wherein the control rules define a mapping relationship between at least one detection result and at least one executable function of one controlled device 200. After receiving the detection result reported by the detection device 100, the server issues a control result defined by a control rule matched with the detection result to the controlled device 200, and the controlled device 200 executes a corresponding operation based on the control result, so as to realize an automatic linkage function based on the detection result.

The inventor has found that in the actual use process, when the detecting device 100 is linked with the controlled device 200, a need often arises to briefly turn off the linkage function of the detecting device 100, for example, after the sweeping robot is turned on, after sleeping, or the like, the linkage function of the detecting device 100 needs to be turned off to prevent false touch. However, the existing detection device 100 does not have such a function, and therefore, an embodiment of the present invention provides a detection device 100, in which the processing module 102 is configured to turn off the reporting function based on the detection result obtained by the radar module according to a turn-off instruction from the application program, so that the user can quickly turn off the automatic linkage function of the detection device 100 when needed.

In one example, the processing module 102 controls the power of the radar module via a switching element, such as, but not limited to, a switching element formed by an electronic switch, such as a MOS transistor, a triode, or the like. When the processing module 102 receives the closing instruction, the switch component is turned off to cut off the power supply of the radar module, and any detection result related to the radar module is not reported any more, so that false triggering caused by that the processing module 102 detects the unmanned detection result in the current space in the closing process of the radar module is prevented. However, directly turning off the power of the radar module may result in the need to turn on the radar module again when the automatic linkage function of the detection apparatus 100 needs to be activated again, and the need to turn on the radar module again (for example, 2 seconds is required for initializing some radar module), which may cause response delay of the detection apparatus 100 due to the need to initialize the radar module when the user activates the radar module again, and may possibly cause false triggering of the processing module during the process of turning on the radar module again. In another example, the processing module 102 stops reporting the detection result based on the radar module after receiving the shutdown command, but does not shutdown the power supply of the radar module. That is, the radar module is still in a normal working state, but the processing module 102 does not report the related detection results (detection results of the current space having a person, the current space having no person, the current space having a person maintaining time, the current space having no person maintaining time, the person approaching, the person leaving, etc.), so that the detection device 100 can only close the data reporting of the detection device 100 without closing the power supply of the radar module, and the above problem is well solved.

Further, for example, the detection device 100 may establish communication connection with a mobile terminal of a user through a data acquisition module such as a WIFI unit or a bluetooth unit, an application program (APP) corresponding to the detection device 100 is running on the mobile terminal, and the user may operate a corresponding control on an interactive interface provided by the APP to issue the closing instruction, so that the user may conveniently close the detection function of the detection device 100 by a quick one-touch operation.

Referring to fig. 4 and fig. 7 to fig. 9, a detection method according to the above embodiment of the present invention is specifically illustrated, and it can be seen that the detection method at least includes step S1 and step S2, wherein:

s1, detecting whether a person exists in a current space;

Referring to fig. 7, in step S2, detecting whether a person exists in a current space within a first delay time specifically includes:

s21, when the person in the current space is identified for the first time, the first time is taken as the starting point of the first delay time, and whether the person in the current space is located or not is identified when the first delay time is ended; if yes, go to step S22; otherwise, go to step S23;

s22, determining that people exist in the current space;

s23, determining that the current space is unmanned.

Referring to fig. 8, in step S1, detecting whether a person is present in a current space includes:

s11, acquiring an action signal of a current space; the action signal is generated by a radar module based on radar detection of the current space; the interval time of the radar module for transmitting the action signal is randomly changed;

s12, analyzing the action signals to identify whether a person exists in the current space.

In addition, in view of the problem that the existing detection device can trigger the unmanned state immediately if the unmanned state is identified once while maintaining the unmanned state, and is easy to cause misjudgment, an embodiment of the present invention provides a detection device 100, which improves the problem of mistriggering of unmanned judgment by reasonably setting a second delay time.

Specifically, according to an embodiment of the present invention, the processing module 102 is configured to operate as:

wherein, the processing module 102 detects whether a person exists in the second recognition state, specifically is used for:

and if the current space is identified as unmanned, detecting whether the current space is occupied or not in the second delay time.

Further, according to this aspect, when the processing module 102 switches from the first recognition state to the second recognition state (i.e., from determining that the current space is unmanned to determining that the current space is occupied), the determination of whether the current space is occupied will be continuously performed, and in order to improve the accuracy of the determination of the occupied space, the determination of the unmanned current space will not be immediately made after the second recognition state is recognized as the unmanned current space, but the determination is continued within the second delay time, and if the unmanned current space is still recognized as occupied within the second delay time, the existence of the current space is determined and the second recognition state is maintained; otherwise, determining that the current space is unmanned and entering a first identification state. To ensure that the accuracy of the state switch from the human-free state is maintained, and to prevent false triggering of the controlled device 200 associated with the state switch event.

According to an embodiment of the present invention, the processing module 102 is further configured to set the second delay time according to an instruction from an application program. And the second delay time can be freely set by the user according to the requirement, for example, when the detection device 100 is set in a living room, a bedroom and other spaces, the probability that the user is judged to be unmanned under the condition of small motion amplitude such as sleeping and film watching can be reduced by properly increasing the second delay time, so that the user experience is improved.

According to the embodiment of the invention, whether the current space is occupied or not is detected in the second delay time, and the method is particularly used for: the first time of identification is used as the starting point of the second delay time after the switch to the second identification state, if the selected space is identified to be occupied N times in the second delay time, the selected space is determined to be occupied; otherwise, determining that the selected space is unmanned; n is an integer greater than or equal to 2. That is, when determining that the current space is occupied, the processing module 102 determines that the current space is occupied at least 2 consecutive times within the second delay time, and if the current space is not determined to be occupied 2 consecutive times (for example, 1 time or 2 times that are discontinuous), ignores and continues to count the time, until the end of the count, and when the current space is determined to be occupied at least 2 times that are not continuously determined to be occupied, the processing module 102 switches to the state of determining that the current space is occupied. Compared with the scheme that only 1 time of identification is carried out in the second delay time to determine the state of the current space with the person, the method and the device can further improve the accuracy of maintaining the state of the person and improve the misjudgment resistance.

In one example, if the second delay time is denoted by T, for example, t=10s, n=3, the specific working principle is as follows: after the processing module 102 switches from determining that the current space is unmanned to determining that the current space is occupied, it needs to enter a determination of maintaining the occupied state (i.e., the second identification state), where t=10s; if people are always in the space, the processing module 102 always recognizes that the current space is occupied and then continuously maintains the state of the people (namely, continuously maintains the second recognition state), after the people in the current space leave, the processing module 102 recognizes that the current space is unmanned, further triggers T to start counting down from 10s when the people in the current space are recognized as unmanned for the first time, and if the processing module 102 does not continuously recognize that three times of people are occupied in the current space in the 10s counting down, the processing module 102 is switched to a state of determining that the current space is unmanned after the 10s counting down is finished; if people exist in the current space once or twice continuously within 10 seconds, neglecting and continuing counting down (the instantaneous interference can be shielded); if the existence of the person in the current space is recognized for three times in 10s, the time of T is ended by recognizing the existence of the person in the current space for the third time, and the T is reset to 10s until the next time of recognizing that the person is not present, and the countdown of the T is triggered again. Space of

According to the embodiment of the invention, the selected space is identified for N times at intervals, namely N times at intervals in the second delay time, and then the selected space is determined; the interval time may be set to 10-100ms, for example, 50ms, then the processing module 102 samples once every 50ms (for example, acquires the action signal of the radar module), and completes the judgment of whether there is a person or not within a microsecond level (for example, if the action signal exceeds the second recognition threshold value, the person is considered to be present, and if the action signal does not exceed the second recognition threshold value, the person is considered to be not present), so that the probability that the interference source with the action duration within 50ms is unidentified will increase, and the transient interference is shielded to a certain extent.

Further, in the actual implementation process, two timers may be set: the first timer and the second timer are used for judging whether the human actions are continuous or not, so that the anti-interference capability is further improved. Specifically, the first timer is configured to sample the action signal once every interval time (e.g., 50 ms), and determine whether the action signal exceeds the second recognition threshold, if so, start the second timer, which is configured to continue sampling the interval time (e.g., continue sampling for 50 ms) at a sampling rate of a subtle level after recognizing that the current space is occupied, so as to determine whether the action duration continues for the interval time, and if so, recognize that the current space is occupied once. And similarly, if the current space is identified as being occupied by three times in succession, determining that the current space is occupied by the person, and maintaining a second identification state so as to prevent misjudgment caused by unmanned triggering. In this way, the source of the disturbance of the action duration in the interval will not be identified, further improving the immunity against transient disturbances.

According to an embodiment of the invention, the processing module 102 is further configured to stop the timing of the delay period when the nth time identifies that the selected space is occupied, so as to reduce power consumption.

According to an embodiment of the present invention, the detecting device 100 further includes a radar module, and the radar module is electrically connected to the processing module 102; the processing module 102 detects whether the current space is occupied, specifically: acquiring an action signal of a current space through a radar module; the radar module sends the action signal to the processing module 102, and the processing module 102 analyzes the action signal to identify whether a person exists in the current space; the interval time of the radar module for transmitting the action signal changes randomly, so that the anti-interference performance is improved by introducing natural random numbers. For example, the interval time varies randomly within 60ms-100 ms.

Referring to fig. 4, 9 and 10, a detection method according to the above embodiment of the present invention is specifically illustrated, and as shown in fig. 3, the detection method at least includes step S1 and step S2, wherein:

s1, detecting whether a person exists in a current space;

as shown in fig. 9, in step S2, whether a person is detected in the second recognition state is specifically configured to:

and S24, if the current space is identified to be unmanned, detecting whether the current space is occupied or not in the second delay time.

Further, if the current space is still identified as someone in the second delay time; then go to step S25; otherwise go to step S26;

s25, determining that people exist in the current space and maintaining a second identification state;

s26, determining that the current space is unmanned and entering a first identification state.

Referring to fig. 10, in step S24, the processing module detects whether a person is in the selected space within the second delay time, which is specifically configured to:

s241, judging whether people in the selected space are identified for N times in the second delay time; if yes, go to step S242; otherwise, go to step S243;

S242, determining that the selected space is occupied;

s243, determining that the selected space is unmanned;

wherein N is an integer greater than or equal to 2.

According to the embodiment of the invention, the starting point of the second delay time when the selected space is not manually identified for the first time, and the timing of the delay time period is stopped when the Nth time identifies that the selected space is occupied.

According to an embodiment of the present invention, detecting whether a person is present in a current space includes:

acquiring an action signal of a current space; the action signal is generated by a radar module based on radar detection of the current space; the interval time of the radar module for transmitting the action signal is randomly changed;

the motion signal is analyzed to identify whether a person is present in the current space.

In addition, the function of identifying people approaching and moving away from the existing detection device 100 is obtained by analyzing the trend of people near the boundary, and the inventor finds that when the detection module 101 is implemented as a single-target detection scheme such as a radar module, the detection module 101 will preferentially identify the person with the largest action amplitude in the current space, and when the current space has a plurality of people, the misjudgment that people still exist in the current space but one person with larger action amplitude moves away from the current space triggers a moving away event may occur. Based on this, in an embodiment of the present invention, a detection apparatus 100 is provided, in which the approaching/separating determination is not dependent on the movement trend of the human body near the boundary, but based on whether the space within the boundary is occupied or not, so that the above-mentioned problem can be effectively avoided.

Specifically, in one embodiment of the present invention, the processing module 102 is configured to operate as:

wherein the processing module 102 is further configured to: after the first recognition state is switched to the second recognition state, if the position of the person is recognized to be within the designated boundary, the person is recognized to be approaching.

Furthermore, according to the present solution, when the current space is switched from the unmanned state to the keep-alive state, even if a person crosses the designated boundary, the processing module 102 will not immediately output a person approaching event, and the determination result of approaching event/keeping away event will not only depend on the person trend when crossing the boundary, but will combine with whether there are any persons in the boundary after the person crosses the boundary to perform the comprehensive determination, so that when there are multiple targets in the current space, the determination result of approaching event/keeping away event is more accurate, and further the misjudgment resistance is improved. For example, when there are multiple people in the current space, if a person with a larger action amplitude passes through the designated boundary and moves away from the designated boundary, the processing module 102 recognizes that the person is not located in the boundary, but does not trigger the person to move away from the boundary, and continues to determine whether the person is located in the designated boundary within a delay period.

Wherein, the detecting device 100 may acquire boundary data through a data acquisition module; the boundary data is used to delineate a specified boundary of approach/departure. The data acquisition module should be understood as any component or combination of components capable of implementing data transceiving, and in particular examples, the data acquisition module may be, for example, but not limited to, a WIFI communication unit, a bluetooth communication unit, or other radio frequency communication unit. Further, for example, the detection device 100 may establish a communication connection with a mobile terminal of a user through the data acquisition module, and the mobile terminal is running an application program (APP) corresponding to the detection device 100, so that the user may freely set a specified boundary on an interactive interface provided by the APP.

According to an embodiment of the invention, the processing module 102 is further arranged to: after the person is identified to be approaching, continuously judging whether the position of the person is within a designated boundary; if the position of the person is not within the appointed boundary, judging whether the position of the person is outside the appointed boundary in a delay period; if yes, identifying that a person is far away; otherwise, the judgment result of the approach of the person is maintained. Furthermore, according to this embodiment, when a human body enters the designated boundary, it will be identified that a person approaches, and the position of the person will be continuously tracked at this time, and when the person crosses the designated boundary and is located outside the designated boundary, the person away event will not be output immediately, but the judgment is continued within the delay period, so as to prevent the processing module 102 from frequently triggering the person approaching event and the person away event when the human body crosses the designated boundary rapidly and back.

The following description will be made with respect to the motion amplitude of a person representing a human body by using an energy value, that is, the larger the energy value is, the larger the motion amplitude of the human body is represented, and the smaller the energy value is, the smaller the motion amplitude of the human body is represented. The existing approach/distancing judgment scheme is as follows: and setting a boundary distance, judging that a person approaches when the human body is recognized to cross the boundary distance and the energy value is gradually increased, and judging that the person approaches when the human body is recognized to cross the boundary distance and the energy value is gradually reduced. This results in: when a plurality of persons exist in the current space, if some persons are watching a movie (energy value is low) and some persons are running (energy value is high), when the running persons leave, it is likely that the running persons are judged that the running persons leave, and misjudgment is caused. The scheme provided by the embodiment can continuously judge whether the position of the person is within the appointed boundary after the person is identified to be close, if the position of the person is identified to be not within the appointed boundary, the person is not immediately triggered to be far away, but a delay period is started, and whether the position of the person is outside the appointed boundary is judged within the delay period; if so, the situation that the person is far away is determined, and further the person in the current space is still effectively avoided, but the person is misjudged to be far away.

According to an embodiment of the present invention, the probe apparatus 100 has a networking function, so that the probe apparatus 100 can implement network connection with a controlled apparatus connected to the same network (for example, the network where the same server is located), so as to perform data interaction and control. The user can customize a plurality of control rules by the mobile phone to be pre-stored in the server, wherein the control rules define a mapping relationship between at least one detection result and at least one executable function of one controlled device 200. After receiving the detection result reported by the detection device 100, the server issues a control result defined by a control rule matched with the detection result to the controlled device 200, and the controlled device 200 executes a corresponding operation based on the control result, so as to realize an automatic linkage function based on the detection result.

The processing module 102 is further configured to report the approach event or the separation event as a detection result to the server, so as to trigger the executable function of the corresponding controlled device 200 according to the preset control rule. Further, the setting of the delay period enables the controlled device 200 to have the effect of delay response after the person leaves, for example, the controlled device 200 is a lighting device, and the light is not turned off immediately after the person is determined to be away, but is turned off again after the delay period.

According to an embodiment of the invention, the processing module 102 is further configured to: after the person is identified as approaching, if the second identification state is switched to the first identification state, the person is identified as moving away. And when the current space is determined to be unmanned, the remote control of the someone is directly triggered without depending on the judgment of whether the human body passes through the appointed boundary, so that the judgment accuracy of the remote control of the someone is improved. That is, after the state of the current space is switched from the occupied state to the unoccupied state, whether the human body passes through the boundary or not, and whether the human body exists in the boundary area or not can be judged as the occupied state. For example, in the application scenario shown in fig. 11, the detection device 100 is disposed at a doorway, where a designated boundary is located in a living room, and a kitchen is located between the living room and the doorway, when a person is located in the designated boundary, the person is triggered to approach, and if the person directly enters the kitchen, the person does not cross the designated boundary again, but is recognized as no person in the whole current space, so that the person is also recognized as being far away.

Further, the processing module 102 may further obtain spatial configuration data through a data obtaining module; the space configuration data is defined by interval L ₁ ～L _m Is generated after being freely selected; wherein L is ₁ ～L _m Characterizing a 1 st section to an m-th section of a space divided into m consecutive sections, m being an integer greater than 1; the processing module 102 is further configured to: forming a current space based on the space configuration data; the current space is made up of all selected intervals.

Furthermore, the detection device 100 can form a current space according to the plurality of intervals selected by the space configuration data, so that a user can freely select a target detection area covered by the current space based on actual requirements and configure the current space in a mode of issuing the space configuration data.

Further, the processing module 102 determines, during a delay period, whether the location of the person is outside the specified boundary, specifically: if the state that all the selected intervals in the designated boundary are free of people is maintained for more than the time delay period, the judgment is that the people are far away, and the approach/the distance are judged in a partition identification mode, so that the judgment efficiency and the judgment precision can be further improved. The delay period is set to 1-20 seconds, for example, 10 seconds, so that the accuracy of the distance judgment of a person is improved, a certain response speed is considered, and the user experience is improved.

In some embodiments, when the processing module 102 determines that the current space is occupied/determines that the current space is unoccupied, the processing module delays reporting the detection result to the network platform (server) after a specified time to relieve an abnormal situation caused by data reporting congestion when the state of the current space is rapidly switched. When the state of the current space is rapidly switched, the corresponding data after the switching is not immediately reported, but is reported after a time delay of a designated time, so that the completion of the last data reporting is ensured. For example, if the specified time is set to 1.5s, if the person in the current space immediately enters the current space again after leaving, the processing module 102 recognizes that the current space is switched from someone to no person for the first data reporting, and immediately detects that the current space is switched from no person to someone, if the corresponding second data reporting is immediately performed, the second data reporting is crowded if the first data reporting is not completed yet, and then unexpected anomalies (such as a crash, etc.) occur, and the second data reporting is performed after delaying for 1.5s, so that the first data reporting can be guaranteed to be completed with a large probability within 1.5s, so as to improve the problem.

Further, the processing module 102 is further configured to report an unmanned duration to the network platform (server) in a first identification state, and report a manned duration to the network platform (server) in a second identification state, where the unmanned duration and the manned duration may be used as the detection result to trigger a corresponding control rule to link related executable functions of the controlled device. Further, the processing module 102 is configured to report the relevant data when the duration of the person or the duration of the person is changed for more than 1 minute, so that the user can view the state of the current space in time.
