Description

Technical Field

[0001] The present invention relates to the technical field of human presence detection control, and in particular to a control system and a control method based on human presence detection. Background Art

[0002] For a long time, sensors could only identify human movement, such as PIR human motion sensors, but could not identify whether a person was present in a certain space. Now, with the advancement of technology, it is possible to identify whether a person is present in a certain space, and control lights or other devices based on the logic of whether a person is present, which greatly improves the experience. For example, in the past, it could only identify human movement. When human movement was identified, the light could be turned on, and then turned off after a delay of a few minutes. At this time, although the person is still in this space, the sensor cannot identify the person because the movement of the person is very weak. Therefore, the application scenarios of previous sensors were limited to corridors, aisles and other occasions where people move, and could not cover some application scenarios of micro-movement of the human body.

[0003] Taking the field of lighting control as an example, controlling lights based on the presence of human bodies can be applied in a wider range, such as in conference rooms or offices. When there are people in the conference room or office, the lights are turned on, and when there are no people, the lights are turned off. Therefore, the entire space is actively controlled without the need to manually turn on and off the lights. This active control experience is very good in most occasions, but there are exceptions. For example, when a conference room needs to play a projection or an office needs a lunch break, although there are people present, they still want to turn off the lights. How to meet the needs of more scenarios based on the human presence sensor is an urgent problem to be solved. Summary of the invention

[0004] One object of the present invention is to provide a control system and a control method based on human presence detection, wherein the execution device can be controlled by the human presence detection device to perform related operations, and can also be controlled by an external device while being controlled by the human presence detection device.

If the execution device is triggered by an external third signal again during the period in which the human presence detection device sends a corresponding signal based on the detection result of the current environment to trigger the execution device to enter a certain operating state, the execution device will maintain the operating state after being triggered by the third signal, and will no longer be controlled by the human presence detection device until the human presence state in the current environment changes once, so that the execution device can temporarily break away from the control of the human presence detection device.

[0006] Another object of the present invention is to provide a control system and control method based on human presence detection, wherein a user can temporarily interrupt the predetermined control logic between the human presence detection device and the execution device through an external remote control, so that the execution device switches and maintains the target operation that the user currently wants to control.

[0029] The embodiments of the present invention will be described in detail below. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] It should be understood that in the description of all embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the existing control system based on human presence detection, the execution device in the system is generally directly controlled by the detection result of the human presence detection device. For example, when there is a person in the environment, the execution device works, and when there is no one in the environment, the execution device does not work. This means that if the user wants the execution device to work, he must be in the corresponding environment to trigger the execution device. If the user is outside the detection environment of the human presence detection device, the execution device cannot be triggered. This makes the triggering method of the execution device too simple, affecting the user experience. Based on this, please refer to Figure 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. Figure 1 As shown, the control system based on human presence detection at least includes: a human presence detection device 100 and an execution device 200.

[0032] Among them, the execution device 200 can be any controlled device that can be linked and controlled by the human presence detection device 100 and can receive and respond to external control signals. In a specific example, the execution device 200 can be, for example, an intelligent wall switch, lighting equipment, television, speaker, air purifier, intelligent electric fan, window pusher, curtain motor, etc.; the control it receives can be, for example but not limited to: being controlled to enter a certain state; for example, turning on or off the relay of the wall switch, turning on or off the lamp of the lighting equipment, turning on or off the TV, turning on or off the speaker, turning on or off the air purifier, turning on or off the electric fan, opening or closing the window, opening or closing the curtain, etc.

[0033] The human presence detection device 100 should be understood as any device or combination of devices that can detect the presence of a human body. In a specific example, the human presence detection device 100 can be a microwave-based human sensor, an image recognition-based camera, a TOF-based structured light sensor, an infrared thermal imaging-based sensor, and other devices that can detect the presence of a person or no one. It can be further understood that any detection device in the art that can detect whether a person is present in an environment can be used as an optional solution for the human presence detection device 100 of this embodiment. In one example, the human presence detection device 100 includes a microwave-based human presence sensor, which is characterized in that it can recognize very small movements of the human body, so it can be used to determine whether a person is present. Of course, in other solutions, the human presence detection device 100 can also be a combination of a microwave-based human presence sensor and an infrared pyroelectric sensor to more accurately detect whether a human body exists.

[0034] It can be understood that, based on the changes in the application fields of the human presence detection device 100, the specific type and controlled functions of the execution device 200 can be arbitrarily changed, and should not deviate from the scope of the embodiments of the present invention.

[0035] According to an embodiment of the present invention, the human presence detection device 100 is configured to detect whether a human body exists in an environment, and can 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 the detection area pointed to by the human presence detection device 100, and the detection area includes a target area when the execution device 200 is working, so that the work between the human presence detection device 100 and the execution device 200 is interrelated; the execution device 200 is configured to be suitable for directly or indirectly forming a coupling relationship with the human presence detection device 100, and can be controlled by the human presence detection device 100 and an external third signal respectively, so as to be suitable for performing a first operation in response to the first signal, performing a second operation different from the first operation in response to the second signal, and performing a third operation for switching the first operation and the second operation in response to the third signal.

[0036] It should be noted that the "coupling" mentioned here and in the following text should be understood in a broad sense, for example, it can be a direct electrical connection, an indirect electrical connection, a wireless connection, a wired connection, etc., which can establish communication. After the connection relationship is established, the execution device 200 can receive the detection result (the first signal or the second signal mentioned above) sent by the human presence detection device 100 and make a corresponding response, and can also send configuration data to the human presence detection device 100 to change some setting items of the human presence detection device 100 (such as unmanned detection time, detection distance, detection sensitivity, etc.).

[0037] It can be seen that based on the above scheme, the execution device 200 in the embodiment of the present invention can be controlled by the human presence detection device 100 to perform related operations, and can also be controlled by an external device (third signal) while being controlled by the human presence detection device 100. 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 can temporarily switch the operation of the execution device 200 through the external third signal when the execution device 200 is associated with the detection result of the human presence detection device 100. In one example, the execution device 200 is a lighting device, the first signal triggers the lighting device to turn on the light, and the second signal triggers the lighting device to turn off the light. Then, when there are people in the environment, the lighting device will be linked to turn on the light. If the user does not want to turn on the light at this time (for example, watching a movie or sleeping), a third signal can be sent through an external device to trigger the lighting device to switch from the light-on state to the light-off state.

[0038] In some embodiments, the second operation is the opposite operation of the first operation; for example, turning on the lights (first operation) or turning off the lights (second operation), turning on the TV (first operation) or turning off the TV (second operation), turning on the speakers (first operation) or turning off the speakers (second operation), turning on the air purifier (first operation) or turning off the air purifier (second operation), turning on the electric fan (first operation) or turning off the electric fan (second operation), etc.

[0039] According to an embodiment of the present invention, the execution device 200 is further configured to be adapted to execute a third operation in response to an external third signal after being controlled by the human presence detection device 100 to execute a corresponding operation, so as to temporarily escape from the control of the human presence detection device 100, until the first signal and the second signal are alternated once, and then the execution device 200 will be controlled by the human presence detection device 100 again. Furthermore, 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 an external device to switch the current operation state of the execution device 200, it means that the user wants to temporarily change the operation state of the execution device 200 in the current period. If the human presence detection device 100 controls the execution device 200 to switch back to the original operation state at this time, it will be contrary to the user's control intention, so the detection result of the human presence detection device 100 will temporarily not control the execution device 200, that is, the execution device 200 can temporarily escape from the control of the human presence detection device 100 at this time. In addition, based on the solution of this embodiment, it is possible to prevent the execution device 200 from repeatedly switching between the first operation and the second operation due to the different target operations pointed to by the human presence detection device 100 and the third signal (for example, the human presence detection device 100 detects that there is no one and controls the light to be turned off. At this time, after the third signal triggers the light to be turned on, the no-one detection device will turn off the light because it detects that there is no one, and then the execution device 200 will repeatedly jump between turning the light on and off). Exemplarily, the execution device 200 temporarily breaks away from the control of the human presence detection device 100, including that the execution device 200 receives the detection result of the human presence detection device 100, but does not respond and still maintains the current operation state. Exemplarily, the execution device 200 temporarily breaks away from the control of the human presence detection device 100, including that the human presence detection device 100 no longer sends a trigger signal to the execution device 200 when the current detection result continues.

[0040] It can be seen that in this embodiment, the human presence detection device 100 can at least generate a first signal and a second signal, and the execution device 200 has at least the ability to perform a first operation and a second operation, the first operation and the second operation are two opposite operations, and the first signal triggers the first operation, and the second signal triggers the second operation. If the execution device 200 is triggered by an external third signal again during the period in which the human presence detection device 100 sends a corresponding signal based on the detection result of the current environment to trigger the execution device 200 to enter a certain operating state, the execution device 200 will maintain the operating state after being triggered by the third signal, and will no longer be controlled by the human presence detection device 100 before the human presence state in the current environment changes once, so that the execution device 200 can temporarily break away from the control of the human presence detection device 100.

[0041] In a further embodiment, the execution device 200 is configured to have a switch function, and correspondingly, the first operation is implemented as an opening operation, and the second operation is implemented as a closing operation; the execution device 200 is further configured as:

[0042] It is suitable for performing a shut-off operation in response to an external third signal after performing an opening operation in response to the first signal, and maintaining the shut-off operation to escape from the control of the human presence detection device 100 when the detection result of the human presence detection device 100 continues to be the first signal, and being controlled by the human presence detection device 100 again after the first signal and the second signal alternate once. Furthermore, when the user is in the environment, he can forcibly control the execution device 200 to perform a shut-off operation through an external remote control to turn off the corresponding device.

[0043] And if the execution device 200 is controlled by an external third signal to perform an opening operation after performing a closing operation in response to the second signal, the opening operation is maintained to break away from the control of the human presence detection device 100 when the detection result of the human presence detection device 100 continues to be the first signal, and after the first signal and the second signal alternate once, the execution device 200 is controlled by the human presence detection device 100 again. Furthermore, the user can control the execution device 200 to perform an opening operation through an external remote control when not in the environment to turn on the corresponding device.

[0044] Based on this embodiment, the user can temporarily interrupt the predetermined control logic between the human presence detection device 100 and the execution device 200 through an external remote control, so that the execution device 200 switches and maintains the target operation that the user currently wants to control.

[0045] In one example, the execution device 200 is implemented as a lighting device, and then the first operation is a light-on operation, and the second operation is a light-off operation. Then there is the following working process: if the user enters the environment, the human presence detection device 100 will detect the presence of the user and generate a first signal, and the lighting device will perform a light-on operation in response to the first signal. At this time, if the user does not want to turn on the light (for example, when watching a movie or sleeping), a third signal can be sent through a remote controller 300 to trigger the lighting device to perform a light-off operation. At this time, even if the human presence detection device 100 still detects the presence of someone in the environment, the lighting device will not turn on the light again until the user leaves the environment and re-enters the environment, and the lighting device will be controlled by the human presence detection device 100 again. In the process of the user leaving the environment and re-entering, the human presence detection device 100 will first recognize the presence of the user and generate a first signal, and then recognize that the user has left the environment and generate a second signal, that is, the first signal and the second signal are alternated once, and then the lighting device will be triggered to turn on the light when the user enters the environment again and generates the first signal.

[0046] Similarly, if the user does not enter the environment, the human presence detection device 100 will detect that there is no human presence and generate a second signal, and the lighting device will execute and maintain the light-off operation in response to the second signal. At this time, if the user wants to turn on the light but does not want to enter the environment, a third signal can be sent through a remote controller 300 to trigger the lighting device to turn on the light. At this time, even if the human presence detection device 100 still detects that there is no one in the environment, the lighting device will not turn off the light again because there is no one in the environment, but will maintain the light-on operation; until the user enters the environment and leaves again, the lighting device will be controlled by the human presence detection device 100 again. In other words, in the process of the user entering the environment from a place far away from the environment and leaving again, the human presence detection device 100 will first recognize that there is no one and generate a second signal, and then recognize that the user enters the environment and generates a first signal, that is, the first signal and the second signal are alternated once, and then recognize that the user leaves the environment and generates the second signal to trigger the lighting device to turn off the light.

[0047] In some embodiments, the second operation is the opposite operation to the first operation; the execution device 200 is further configured to: after being controlled by the human presence detection device 100 to perform the corresponding operation, if it is controlled by an external third signal to perform the third operation twice, it will be directly controlled by the human presence detection device 100 again to avoid being out of the control of the human presence detection device 100. It should be noted that the two third operations should be triggered based on the two third signals respectively. For example, after the human presence detection device 100 controls the execution device 200 to perform the first operation, the user controls the execution device 200 to perform the third operation once to flip the second operation through the external third signal. During the period when the human presence detection device 100 continuously detects a person and generates the first signal, the user controls the execution device 200 to perform the second third operation again through the external third signal to flip to the first operation. After that, the execution device 200 will be able to directly respond to the second signal of the human presence detection device 100 to perform the second operation and will not be out of the control of the human presence detection device 100. Therefore, based on this embodiment, the user can operate the execution device 200 twice through the third signal to return the execution device 200 to the operating state before being operated by the third signal, thereby preventing the human presence detection device 100 from losing control of the execution device 200.

[0048] In some embodiments, before the remote controller 300 controls the execution device 200, the two need to be bound. It is understandable that the execution device 200 can be bound to multiple remote controllers 300 to be controlled by multiple remote controllers 300, and one remote controller 300 can also be paired with multiple execution devices 200 to remotely control multiple execution devices 200. After 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 device 200 is configured to: be able to enter a binding mode via a trigger instruction, and be able to receive and maintain inherent identification information (such as MAC address, product ID, etc., which is factory-provided and unique information) from the remote controller 300 in the binding mode 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 the identification information contained in the received third signal is at least one of the multiple identification information being maintained; if so, respond to the third signal, otherwise do not respond. The inherent identification information may be included in a binding message sent by the remote controller 300 , such as a network configuration message based on a predetermined protocol format (a standard protocol such as Bluetooth, WiFi, or a user-defined protocol).

[0049] In one example, the trigger instruction is a trigger instruction formed by physical manipulation, for example, by long pressing a button of the execution device 200 to trigger it to enter binding mode. However, when the execution device 200 is installed in a position that is not easily touched (for example, installed in a suspended ceiling), it will cause inconvenience in operation. Therefore, 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. Furthermore, the trigger instruction is a trigger instruction generated based on a wireless control signal, such as a trigger instruction sent by an application on a mobile phone. After receiving the wireless control signal, the execution device 200 enters a signal receiving state to receive the binding message emitted by the remote control 300 and carrying inherent identification information that can characterize the identity of the remote control 300. After establishing a correspondence with the remote control 300, the execution device 200 receives the third signal sent by the remote control 300 based on a point-to-point communication method, for example, through WiFi direct connection, Bluetooth direct connection, 433MHz radio frequency communication, NFC, etc., to increase the transmission efficiency of the third signal, reduce control delays, and prevent the third signal from being intercepted and attacked due to a long transmission distance (for example, through a network). Security risks.

[0050] The remote controller 300 can be understood as any wired control device or wireless control device that can realize the remote control function, such as a wall switch with wireless control function, a wall switch with power carrier communication function, a battery wireless switch, a self-generated wireless switch, a Bluetooth speaker with voice control function, etc. In a specific example, the remote controller 300 is powered by self-generation, and can be powered by an electromagnetic induction micro-generator or a piezoelectric ceramic micro-generator. Correspondingly, the third signal is sent out in a broadcasting manner to reduce energy consumption. At the same time, the self-generation mode can reduce the use of batteries and save energy and protect the environment.

[0051] In some embodiments, the human presence detection device 100 and the execution device 200 are directly electrically connected and integrated, that is, the human presence detection device 100 is integrated into the execution device 200 to establish a direct electrical connection between the two. Figure 2As shown, this embodiment provides a specific structural block diagram when the human presence detection device 100 and the execution device 200 are integrated into one, wherein the human presence detection device 100 includes an HLK-LD2410 radar module 100, and the execution device 200 includes a lighting control circuit for controlling the on and off of a lamp 400 composed of a relay 202, a Bluetooth module 201 and some peripheral circuits (rectification, voltage conversion, drive, etc.) necessary for the normal operation of the circuit; wherein the radar module 100 and the lighting control circuit are both arranged on a circuit carrier (such as a PCB circuit board) and are packaged in a shell to form an integrated The working principle of the device with human detection function and on-off control function is as follows: the Bluetooth module 201 drives the relay 202 to be attracted and disconnected through the driving circuit, thereby controlling the power on and 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, which detects whether there is a person in the environment by radiating detection microwaves into the environment, and sends the detection result to the Bluetooth module 201. The Bluetooth module 201, as the hub of data processing and control, will implement control of the relay 202 based on the detection result to control the lamp 400 to perform related operations (turning on or off the light, etc.). In addition, the Bluetooth module 201 can also receive the wireless control signal of the external remote control 300 (such as a wireless battery) through Bluetooth communication, and then control the attraction and disconnection of the relay 202 based on the wireless control signal.

[0052] In addition, in some embodiments, the human presence detection device 100 and the execution device 200 may also be two independent devices that are separately arranged and are communicatively connected through wired or wireless signals, for example, through Bluetooth communication protocol, WIFI communication protocol, ZIGBEE communication protocol, and / or power carrier communication protocol to establish a communicative connection relationship.

[0053] See also Figure 3 Based on the above control system, an embodiment of the present invention further provides a control method based on human body detection. Furthermore, the relevant description of the control method in this embodiment can be understood as a description of the working process, function, and specific implementation method of the software and / or hardware in the above control system.

[0054] Specifically, Figure 2 As shown, the control method based on human body detection at least includes steps S1 to S3:

[0055] S1. Detecting whether a human body exists in an environment by a human body presence detection device, and generating a first signal when a human body exists in the environment, and generating a second signal when no human body exists in the environment;

[0056] S2. directly controlling an execution device through the human presence detection device, so that the execution device is suitable for executing a first operation in response to a first signal, and is suitable for executing a second operation different from the first operation in response to a second signal;

[0057] S3. Control the execution device to execute a third operation through an external third signal; wherein the third operation is used to switch the first operation and the second operation.

[0058] The order of steps S1 to S3 can be adaptively adjusted based on actual applications, and the serial numbers S1 to S3 are only used for the convenience of description and should not be understood as limiting the execution order of the steps of the method in this embodiment. The human presence detection device, execution device, etc. in this embodiment can be understood by referring to the records in the above embodiments, and the same parts will not be repeated in this embodiment.

[0059] Based on this, an embodiment of the present invention proposes a control method based on human body detection, wherein the execution device can be operated not only by the human body presence detection device, but also by an external signal. Specifically, the execution device in the embodiment of the present invention can be controlled by the human body presence detection device to perform related operations, and can also be controlled by an external device (third signal) while being controlled by the human body presence detection device. The external third signal is used to trigger the execution device to switch the first operation and the second operation, so that the user can temporarily switch the operation of the execution device through the external third signal when the execution device is associated with the detection result of the human body presence detection device.

[0060] In some embodiments, the second operation is the opposite operation to the first operation; Figure 4 As shown, the method also includes:

[0061] S4. During the continuous period after the execution device is controlled by the human presence detection device to execute the corresponding operation, if it is controlled by an external third signal to execute a third operation, it will temporarily be separated from the control of the human presence detection device until the first signal and the second signal alternate once, and then it will be controlled by the human presence detection device again.

[0062] It can be seen that in this embodiment, the human presence detection device can at least generate a first signal and a second signal, and the execution device has at least the ability to perform a first operation and a second operation, the first operation and the second operation are two opposite operations, and the first signal corresponds to triggering the first operation, and the second signal corresponds to triggering the second operation. If the execution device is triggered by an external third signal again during the period when the human presence detection device sends a corresponding signal based on the detection result of the current environment to trigger the execution device to enter a certain operation state, the execution device will maintain the operation state after being triggered by the third signal, and will no longer be controlled by the human presence detection device before the human presence state in the current environment changes once, so that the execution device can temporarily break away from the control of the human presence detection device.

[0063] In some embodiments, the execution device has a switch function, and correspondingly, the first operation is implemented as an opening operation, and the second operation is implemented as a closing operation; step S4 is further configured as follows:

[0064] S41, if the execution device is controlled by an external third signal to execute a shut-down operation after executing an opening operation in response to the first signal, the shut-down operation is maintained to break away from the control of the human presence detection device when the detection result of the human presence detection device continues to be the first signal, and after the first signal and the second signal alternate once, the execution device is controlled by the human presence detection device again. Furthermore, the user can forcibly control the execution device to perform a shut-down operation through an external remote control when in the environment to shut down the corresponding device.

[0065] S42: If the execution device is controlled by an external third signal to execute an opening operation after executing a closing operation in response to the second signal, the opening operation is maintained to break away from the control of the human presence detection device when the detection result of the human presence detection device continues to be the first signal, and after the first signal and the second signal alternate once, the execution device is controlled by the human presence detection device again. In addition, the user can control the execution device to perform an opening operation through an external remote control when not in the environment to turn on the corresponding device.

[0066] In some embodiments, the second operation is the opposite operation to the first operation; Figure 5 As shown, the method also includes:

[0067] S5. During the period after the execution device is controlled by the human presence detection device to execute the corresponding operation, if it is controlled by an external third signal to execute two consecutive third operations, it is directly controlled by the human presence detection device again to avoid being out of control of the human presence detection device. Therefore, based on this embodiment, the user can operate the execution device twice through the third signal to make the execution device return to the operating state before being operated by the third signal, thereby preventing the human presence detection device from being out of control of the execution device.

[0068] In some embodiments, before step S3, the method further includes:

[0069] S21, triggering the execution device to enter a binding mode via a trigger instruction, wherein the execution device receives and maintains inherent identification information from a remote controller in the binding mode to establish a correspondence with the remote controller. After establishing a correspondence with the remote controller, the execution device receives a third signal from the remote controller to switch between the first operation and the second operation.

[0070] In some embodiments, the trigger instruction originates from a mobile smart terminal; the execution device receives the trigger instruction and the third signal wirelessly.

[0071] In some embodiments, the remote controller is powered by self-generation; and the third signal is sent out in the form of broadcast.

[0072] In some embodiments, the execution device includes at least one of the following: a smart light, a curtain motor, a smart window pusher, an air conditioner, a television, a humidifier, and a speaker;

[0073] The human presence detection device is integrated into the execution device to establish a direct electrical connection between the two; or,

[0074] The human presence detection device and the execution device are separately arranged, and a communicative connection relationship is established through a Bluetooth communication protocol, a WIFI communication protocol, a ZIGBEE communication protocol, and / or a power carrier communication protocol.

[0075] In some embodiments, the execution device receives the third signal via at least one of Bluetooth, WIFI, ZIGBEE, and / or power carrier communication.
