Description
Technical Field
The invention relates to the technical field of human body presence detection control, in particular to a control system and a control method based on human body presence detection.
Background
For a long time, the sensor can only recognize the motion of a human body, such as a PIR human body motion sensor, but cannot recognize whether the human body exists in a certain space, now with the progress of technology, whether a human body exists in a certain space can be recognized, and a lamp or other equipment can be controlled based on logic of whether the human body exists, so that the experience is greatly improved. For example, only human body movement can be recognized before, when human body movement is recognized, a lamp can be turned on, then the lamp is turned off after a few minutes, and at the moment, although a person is still in the space, the sensor cannot recognize the human body movement because the human body movement is very weak. Therefore, the application scene of the prior sensor is only the occasion of human body movement such as corridor, passageway and the like, and can not cover the application scene of some human body micro-movements.
By taking the light control field as an example, the light control device can be applied to a wider range based on the existence of a human body, for example, in places such as a conference room or an office, when people exist in the conference room or the office, the light is controlled to be turned on, and when people do not exist, the light is controlled to be turned off. Therefore, the active control of the whole space is realized, and the lamp does not need to be manually turned on or off. The active control is very good in experience in most occasions, but has exceptional scenes, such as meeting rooms needing to play projection or offices needing noon break, and the situation that the light is turned off and how to meet the requirements of more scenes on the basis of the presence of a human body sensor is still hoped to be solved is a urgent problem.

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 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.
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.
In the existing control system based on human body presence detection, the execution device in the detection result control system of the human body presence detection device generally directly works through the execution device, for example, when a person exists in the environment, the execution device does not work when no person exists in the environment. If the user wants to execute the device, the user can trigger the execution device in the corresponding environment, and if the user is outside the detection environment of the human body presence detection device, the user cannot trigger the execution device, so that the triggering mode of the execution device is too single, and the user experience is affected. Based on this, referring to fig. 1, an embodiment of the present invention provides a control system based on human presence detection, wherein the execution device 200 can be operated not only by the human presence detection device 100 but also by an external signal. As shown in fig. 1, the control system based on human presence detection at least includes: a human presence detection device 100 and an execution device 200.
The executing device 200 may be any controlled device that can be controlled by the human body presence detecting device 100 in a linkage manner and can receive and respond to external control signals, and in particular examples, the executing device 200 may be an intelligent wall switch, an illumination device, a television, a sound box, an air purifier, an intelligent electric fan, a window opener, a curtain motor, etc.; the control it is subjected to may be, for example, but not limited to: is controlled to enter a certain state; such as relays to turn on or off wall switches, lights to turn on or off lighting, televisions to turn on or off speakers, air cleaners to turn on or off fans, windows to turn on or off curtains, etc.
The human presence detection apparatus 100 should be understood as any device or combination of devices that can implement human presence detection, and in a specific example, the human presence detection apparatus 100 may be a device that can implement human presence detection and unmanned presence detection, such as a microwave-based human body sensor, an image recognition-based camera, a TOF-based structured light sensor, an infrared thermal imaging-based sensor, and the like. It is further understood that any detection device capable of detecting the presence of a person in the environment may be used as an alternative to the human presence detection apparatus 100 of the present embodiment. In one example, the human presence detection device 100 includes a microwave-based human presence sensor that is characterized by very small movements of the human body that can be identified and thus used to determine whether a person is present. Of course, in other embodiments, the human presence detection device 100 may also be combined with a microwave-based human presence sensor and an infrared pyroelectric sensor to more accurately detect the presence of a human body.
It will be appreciated that the specific type and controlled function of the device 200 may be arbitrarily changed based on the change in the application field of the human presence detection device 100, and should not depart from the scope of the embodiments of the present invention.
According to an embodiment of the invention, the human presence detection means 100 are arranged to detect the presence of a human in an environment and to generate a first signal for characterizing the presence of a person in the environment and a second signal for characterizing the absence of a person in the environment; the environment should be understood as a detection area to which the human presence detection device 100 is directed, the detection area including a target area when the execution device 200 is operated, such that the operation between the human presence detection device 100 and the execution device 200 is interrelated; the execution means 200 is arranged to be in a coupled relationship with the human presence detection device 100 directly or indirectly and to be controllable by the human presence detection device 100 and an external third signal, respectively, to be adapted to perform a first operation in response to a first signal, a second operation different from the first operation in response to a second signal, and a third operation for switching between the first operation and the second operation in response to the third signal.
It should be noted that "coupling" referred to herein and hereinafter is to be understood in a broad sense, and may be, for example, a connection manner capable of establishing communication, such as a direct electrical connection, an indirect electrical connection, a wireless connection, a wired connection, or the like. After establishing the connection, the executing device 200 may receive the detection result (the first signal or the second signal) sent by the human presence detecting device 100 and respond accordingly, or may send configuration data to the human presence detecting device 100 to change some setting items (such as unmanned detection time, detection distance, detection sensitivity, etc.) of the human presence detecting device 100.
It can be seen that, based on the above-mentioned scheme, the executing device 200 in the embodiment of the present invention can be controlled by the human presence detecting device 100 to execute the related operation, and can be controlled by an external device (third signal) while being controlled by the human presence detecting device 100. Wherein the external third signal is used to trigger the execution device 200 to switch the first operation and the second operation, so that the user temporarily switches the operation of the execution device 200 by the external third signal in case the execution device 200 is associated with the detection result of the human presence detection device 100. In one example, the executing device 200 is a lighting device, the first signal triggers the lighting device to turn on, and the second signal triggers the lighting device to turn off. Further, when someone is in the environment, the lighting device is linked to turn on the lamp. If the user does not want to turn on the lamp at this time (e.g. watching a movie or sleeping), a third signal may be sent by the external device to trigger the lighting device to switch from the on state to the off state.
In some embodiments, the second operation is a reverse operation to the first operation; for example, turning on the lamp (first operation) or turning off the lamp (second operation), turning on the television (first operation) or turning off the television (second operation), turning on the sound box (first operation) or turning off the sound box (second operation), turning on the air cleaner (first operation) or turning off the air cleaner (second operation), turning on the electric fan (first operation) or turning off the electric fan (second operation), etc. as described in the above embodiments.
According to an embodiment of the present invention, the execution device 200 is further configured to execute a third operation in response to an external third signal after the corresponding operation is executed by the human presence detection device 100, so as to temporarily disengage from the control of the human presence detection device 100, until the first signal and the second signal are alternated once, and then to be controlled again by the human presence detection device 100. Further, when the execution device 200 is triggered by the human presence detection device 100 and is in a certain operation state, if the user sends a third signal through the external device to switch the current operation state of the execution device 200, it indicates that the user wants to temporarily change the operation state of the execution device 200 in the current period, and if the human presence detection device 100 again controls the execution device 200 to switch back to the original operation state, the control intention of the user is contradicted, so that the detection result of the human presence detection device 100 will not temporarily control the execution device 200 at this time, that is, the execution device 200 can temporarily be disconnected from the control of the human presence detection device 100 at this time. Furthermore, according to the solution of the present embodiment, it is possible to prevent the execution device 200 from repeatedly switching between the first operation and the second operation due to the difference between the target operations to which the human presence detection device 100 and the third signal are directed (for example, the human presence detection device 100 detects no person to control the light turning-off, and after the third signal triggers the light turning-on, the human presence detection device turns off due to the detection of no person, and the execution device 200 repeatedly jumps between the light turning-on and the light turning-off). Illustratively, the executing device 200 temporarily disengages from the control of the human presence detecting device 100, including when the executing device 200 receives the detection result of the human presence detecting device 100, but remains in the current operation state without any response. Illustratively, the executing device 200 temporarily disengages from the control of the human presence detecting device 100, including that the human presence detecting device 100 no longer transmits a trigger signal to the executing device 200 if it is continuously the current detection result.
It can be seen that, in this embodiment, the human presence detection device 100 is at least capable of generating a first signal and a second signal, the execution device 200 is at least capable of performing a first operation and a second operation, the first operation and the second operation are opposite, the first signal correspondingly triggers the first operation, and the second signal correspondingly triggers the second operation. If the execution device 200 is triggered once by the external third signal again in a duration that the human presence detection device 100 sends a corresponding signal to trigger the execution device 200 to enter a certain operation state based on the detection result of the current environment, the execution device 200 will maintain the operation state triggered by the third signal and will not be controlled by the human presence detection device 100 until the human presence state changes once in the current environment, so that the execution device 200 can temporarily disengage from the control of the human presence detection device 100.
In a further embodiment, the executing device 200 is configured to have a switching function, and correspondingly, the first operation is implemented as an on operation and the second operation is implemented as an off operation; the execution device 200 is further configured to:
Is adapted to perform an off operation in response to an external third signal after performing an on operation in response to the first signal, and to maintain the off operation to be out of control of the human presence detection device 100 in a case where the detection result of the human presence detection device 100 is continuously the first signal, and to be controlled again by the human presence detection device 100 after the first signal and the second signal are alternated once. Further, the user can forcibly control the execution apparatus 200 to perform a turn-off operation by an external one-time remote control while in the home environment to turn off the corresponding device.
And the executing device 200, if being controlled by an external third signal to execute the opening operation after executing the closing operation in response to the second signal, maintains the opening operation to be separated from the control of the human presence detecting device 100 in the case that the detection result of the human presence detecting device 100 is continuously the first signal, and is controlled by the human presence detecting device 100 again after the first signal and the second signal are alternated once. Further, the user can control the execution apparatus 200 to perform an opening operation by an external one-time remote control to open the corresponding device when not in the environment.
Based on the present embodiment, the user can temporarily interrupt the predetermined control logic between the human presence detection device 100 and the execution device 200 through the external remote control, so that the execution device 200 switches and maintains the target operation that the user currently wants to control.
In one example, the executing device 200 is implemented as a lighting device, and further, the first operation is a light-on operation and the second operation is a light-off operation. The following working procedure is followed: if the user enters the environment, the human presence detection device 100 detects the presence of the user and generates a first signal, the lighting device performs a lighting operation in response to the first signal, and if the user does not want to turn on the light (for example, when the user needs to watch a movie or sleep), a third signal may be sent through a remote controller 300 to trigger the lighting device to perform a lighting operation, and at this time, even if the human presence detection device 100 still detects that a person exists in the environment, the lighting device will not turn on again until the user leaves the environment and enters the environment again, and the lighting device is controlled by the human presence detection device 100 again. In the process that the user leaves from the environment and reenters, the human presence detection device 100 first recognizes that the user exists to generate a first signal, then recognizes that the user leaves from the environment to generate a second signal, that is, the first signal and the second signal alternate once, and then recognizes that the user reenters from the environment to generate the first signal, the lighting device is triggered to turn on.
Similarly, if the user does not enter the environment, the human presence detection device 100 will detect the presence of the human being and generate a second signal, and the lighting apparatus performs and maintains the light-off operation in response to the second signal. At this time, if the user wants to turn on the light and does not want to enter the environment, the third signal may be sent by a remote controller 300 to trigger the lighting device to perform the light-on operation, and even if the human existence detection device 100 still detects that no person exists in the environment, the lighting device will not turn off the light again because of no person in the environment, but keeps the light-on operation; the lighting device is not controlled again by the human presence detection means 100 until the user enters the environment and leaves again. In other words, in the process that the user enters the environment from a place far away from the environment and moves away again, the human presence detection device 100 first recognizes that no person exists to generate the second signal, then recognizes that the user enters the environment to generate the first signal, that is, the first signal and the second signal are alternated once, and then recognizes that the user leaves the environment to generate the second signal, the lighting device is triggered to turn off.
In some embodiments, the second operation is a reverse operation to the first operation; the execution apparatus 200 is further configured to: after the corresponding operation is performed by being controlled by the human presence detection device 100, if the external third signal controls the operation to be performed twice, the operation is directly controlled by the human presence detection device 100 again, so as to avoid the control of the human presence detection device 100 from being separated. It should be noted that, the two third operations should be triggered based on the two third signals, for example, after the human presence detecting device 100 controls the executing device 200 to execute the first operation, the user performs the third operation to turn over the second operation through the external third signal controlling the executing device 200, and during the period that the human presence detecting device 100 continuously detects the presence of a person and generates the first signal, the user performs the third operation again through the external third signal controlling the executing device 200 to turn over to the first operation, and then the executing device 200 can directly respond to the second signal of the human presence detecting device 100 to execute the second operation without departing from the control of the human presence detecting device 100. Therefore, according to the present embodiment, the user can operate the execution device 200 twice by the third signal so that the execution device 200 returns to the operation state before being operated by the third signal, preventing the human presence detection device 100 from disengaging the control of the execution device 200.
In some embodiments, before the remote controller 300 controls the execution device 200, binding the two needs to be performed, it is understood that the execution device 200 may be bound with a plurality of remote controllers 300 to be controlled by the plurality of remote controllers 300, one remote controller 300 may also be paired with a plurality of execution devices 200 to remotely control the plurality of execution devices 200, and after the binding, the remote controller receives a third signal from the remote controller 300 to switch the first operation and the second operation; specifically, the execution apparatus 200 is configured to: the binding mode can be entered via a trigger instruction, and intrinsic identification information (e.g., MAC address, product ID, etc. from the remote controller 300 and unique information from the factory) can be received and maintained in the binding mode, so as to establish a correspondence with the remote controller 300, and complete the binding with the remote controller 300. In the control after the correspondence is established, it is determined whether or not the identification information contained in the received third signal is at least one of the plurality of pieces of identification information held; if yes, responding to the third signal, otherwise, not responding. The inherent identification information may be included in a binding message sent by the remote controller 300, for example, a network allocation message based on a predetermined protocol format (standard protocols such as bluetooth, wifi, etc., or a custom protocol).
In one example, the trigger is a trigger formed by physical manipulation, for example, by pressing a button of the execution device 200 for a long time to trigger it into a binding mode. However, when the actuator 200 is installed in a location that is not easily touched (e.g., in a suspended ceiling), it may cause inconvenience in operation. Thus, in a further example, the trigger instruction originates from a mobile smart terminal, and the execution device 200 receives the trigger instruction and the third signal wirelessly. Further, the triggering command is a triggering command generated based on a wireless control signal, for example, the triggering command is sent by an application program of a mobile phone, and after receiving the wireless control signal, the executing device 200 enters a signal receiving state to receive a binding message which is emitted by the remote controller 300 and carries inherent identification information capable of representing the identity of the remote controller 300. After the execution device 200 receives the third signal sent by the remote controller 300 based on the peer-to-peer communication manner after the execution device establishes a correspondence with the remote controller 300, for example, the third signal may be sent in a WiFi direct connection manner, a bluetooth direct connection manner, a 433MHz radio frequency communication manner, an NFC manner, etc., so as to increase the sending efficiency of the third signal, reduce the control delay, and prevent the security risk that the third signal may be intercepted and attacked due to the fact that the third signal is too far in transmission distance (for example, passes through a network).
The remote controller 300 may be understood as any wired control device or wireless control device capable of implementing a remote control function, for example, a wall switch with a wireless control function, a wall switch with a power carrier communication function, a battery wireless switch, a self-generating wireless switch, a bluetooth speaker with a voice control function, and the like. In a specific example, the remote controller 300 is powered by a self-generating mode, and may specifically use an electromagnetic induction micro-generator or a piezoelectric ceramic micro-generator to supply power, and correspondingly, the third signal is sent outwards in a broadcast mode, so as to reduce energy consumption, and meanwhile, the self-generating mode is used for supplying power, so that the use of a battery can be reduced, and the energy-saving and environment-friendly effects are achieved.
In some embodiments, the human presence detection device 100 and the execution device 200 are directly electrically connected and integrally provided, i.e. the human presence detection device 100 is integrated with the execution device 200 to establish a direct electrical connection therebetween. As shown in fig. 2, the present embodiment provides a specific block diagram of the human presence detection device 100 and the executing device 200 when integrated, wherein the human presence detection device 100 includes an HLK-LD2410 radar module 100, and the executing device 200 includes a lighting control circuit for controlling the power on/off of a lamp 400, which is composed of a relay 202, a bluetooth module 201, and peripheral circuits (rectification, voltage conversion, driving, etc.) necessary for normal operation of some circuits; the radar module 100 and the lighting control circuit are both disposed on a circuit carrier (e.g., PCB), and are packaged in a housing to form a device integrating a human body detection function and an on-off control function, and the working principle thereof is as follows: the bluetooth module 201 drives the relay 202 to be closed and opened through the driving circuit, so as to control the power on and power off (turning on and off) of the lamp 400 powered by the relay 202; the radar module 100 is electrically connected to the bluetooth module 201, and detects the presence of a person in the environment by radiating a detection microwave into the environment, and transmits the detection result to the bluetooth module 201, and the bluetooth module 201, as a center for data processing and control, performs control of the relay 202 based on the detection result to control the lamp 400 to perform related operations (turning on or off a lamp, etc.). In addition, the bluetooth module 201 can also receive a wireless control signal of the external remote controller 300 (such as a wireless battery) through bluetooth communication, so as to control the on and off of the relay 202 based on the wireless control signal.
Furthermore, in some embodiments, the human presence detection apparatus 100 and the execution apparatus 200 may also be two separate devices separately configured and communicatively connected by a wired or wireless signal, for example, by a bluetooth communication protocol, a WIFI communication protocol, a ZIGBEE communication protocol, and/or a power carrier communication protocol to establish a communicable connection relationship.
Referring to fig. 3, based on the control system, an embodiment of the present invention further provides a control method based on human body detection, and further, in this embodiment, the description of the control method may be understood as a description of the working process, the function, and the specific implementation of software and/or hardware in the control system.
Specifically, as shown in fig. 2, the control method based on human body detection at least includes steps S1 to S3:
s1, detecting whether a human body exists in an environment or not through a human body existence detection device, generating a first signal when a person exists in the environment, and generating a second signal when the person does not exist in the environment;
s2, directly controlling an executing device through the human body existence detecting device, so that the executing device is suitable for responding to a first signal to execute a first operation and responding to a second signal to execute a second operation different from the first operation;
S3, controlling the execution device to execute a third operation through an external third signal; wherein a third operation is used to switch the first operation and the second operation.
The order of steps S1 to S3 may be adaptively adjusted based on practical applications, and the order of steps S1 to S3 is only for convenience of description and should not be construed as limiting the execution order of the steps of the method in this embodiment. The human body presence detecting device, the executing device, etc. in this embodiment can be understood by referring to the descriptions in the above embodiments, and the same parts will not be repeated in this embodiment.
Based on this, an embodiment of the present invention proposes a control method based on human body detection, in which the execution device can be operated not only by the human body presence detection device but also by an external signal. Specifically, the executing device in the embodiment of the invention can be controlled by the human body presence detecting device to execute the related operation, and can be controlled by the external device (third signal) while being controlled by the human body presence detecting device. Wherein the external third signal is used for triggering the execution device to switch the first operation and the second operation, so that a user can temporarily switch the operation of the execution device through the external third signal under the condition that the execution device is related to the detection result of the human body presence detection device.
In some embodiments, the second operation is a reverse operation to the first operation; as shown in fig. 4, the method further includes:
and S4, if the execution device is controlled by an external third signal to execute a third operation within a duration after the execution device is controlled by the human body existence detection device to execute the corresponding operation, the execution device is temporarily separated from the control of the human body existence detection device until the first signal and the second signal are alternated once, and the execution device is controlled by the human body existence detection device again.
It can be seen that, in this embodiment, the human presence detecting device is at least capable of generating a first signal and a second signal, and the executing device is at least capable of performing a first operation and a second operation, where the first operation and the second operation are opposite, the first signal correspondingly triggers the first operation, and the second signal correspondingly triggers the second operation. If the execution device is triggered once by the external third signal within a duration that the human body presence detection device sends a corresponding signal to trigger the execution device to enter a certain operation state based on a detection result of the current environment, the execution device keeps the operation state triggered by the third signal and is not controlled by the human body presence detection device before the human body presence state changes once in the current environment, so that the execution device can be temporarily separated from the control of the human body presence detection device.
In some embodiments, the executing means is provided with a switching function, and correspondingly, the first operation is implemented as an on operation and the second operation is implemented as an off operation; step S4 is further configured to:
and S41, if the executing device is controlled by an external third signal to execute the turn-off operation after responding to the first signal to execute the turn-on operation, the turn-off operation is maintained to be separated from the control of the human body presence detecting device under the condition that the detection result of the human body presence detecting device is continuously the first signal, and the first signal and the second signal are controlled by the human body presence detecting device again after alternating once. Further, the user can forcibly control the execution device to perform the turn-off operation by an external one-time remote control while in the home environment to turn off the corresponding device.
And S42, if the execution device is controlled by an external third signal to execute the opening operation after responding to the second signal to execute the closing operation, the opening operation is maintained to be separated from the control of the human body presence detection device under the condition that the detection result of the human body presence detection device is continuously the first signal, and the first signal and the second signal are controlled by the human body presence detection device again after alternating once. Further, the user can control the execution device to perform the opening operation by the external one-time remote control to open the corresponding apparatus when not in the environment.
In some embodiments, the second operation is a reverse operation to the first operation; as shown in fig. 5, the method further includes:
s5, in the duration of the execution device controlled by the human body presence detection device to execute the corresponding operation, if the execution device is controlled by an external third signal to execute the third operation twice continuously, the execution device is directly controlled by the human body presence detection device again, so that the execution device is prevented from being separated from the control of the human body presence detection device. Therefore, according to the present embodiment, the user can operate the execution device twice by the third signal to return the execution device to the operation state before being operated by the third signal, preventing the human presence detection device from being out of control of the execution device.
In some embodiments, step S3 is preceded by:
s21, triggering the execution device to enter a binding mode through a triggering instruction, wherein the execution device receives and holds inherent identification information from a remote controller in the binding mode so as to establish correspondence with the remote controller. And further, after the correspondence with the remote controller is established, receiving a third signal from the remote controller to switch the first operation and the second operation.
In some embodiments, the trigger instruction originates from a mobile smart terminal; the execution device receives the trigger instruction and the third signal in a wireless mode.
In some embodiments, the remote control is powered by self-generating electricity; the third signal is transmitted outwardly in the form of a broadcast.
In some embodiments, the execution means comprises at least one of: intelligent lamps, curtain motors, intelligent window pushers, air conditioners, televisions, humidifiers and sound boxes;
