Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be made on the specific implementation and effects of the human body detection method and the human body detection device according to the present invention with reference to the accompanying drawings and preferred embodiments.
An embodiment of the present invention provides a human body detection method, which is used for a human body detection device, as shown in fig. 1, and includes:
and step S10, acquiring the current preset working mode of the human body detection device.
In an embodiment, in order to enable the human body detection device to meet different use requirements of different crowds, a preset working mode can be performed on the human body detection device.
Specifically, the operation mode may include an all-day operation mode, a night operation mode, and the like. For example, when a person moves in a room for a long time (for example, when the old person lives in a home), the human body detection device is frequently triggered, so that when the human body detection device detects a human body, the server is frequently reported, and further, resources are wasted. When the human body detection device is powered by a battery, the service life of the battery is shortened due to frequent detection or information reporting, and the battery needs to be replaced frequently. Under the condition, the user only needs to perform human body detection after falling asleep, and therefore the working mode only needs to be adjusted to the night working mode. When no person is in the room (for example, the user needs to work in the daytime), the all-day working mode can be started to ensure that no person is in the room to monitor the room. Of course, the detection device can be used when the whole family is out, when no person exists in the room, the detection device is started, and when a person exists in the room, the detection device is closed.
Regarding the preset working mode, the preset working mode can be realized by adding a mode selection unit on the human body detection device, for example, a dial device can be added in the human body detection device, and a user only needs to set the working mode of the human body detection device by the dial mode. The working mode of the human body detection device can be set in a software mode. For example, the operation mode of the human body detection device is set by the mobile phone APP.
Step S20, when the current operating mode is the first operating mode, obtaining the current illumination intensity of the current environment.
Specifically, when the user turns on the night operation mode (i.e., the first operation mode) of the human body detection device, it cannot be said that no person is moving in the room. For example, during night work or watching television. Therefore, even if the night mode of the human body detection device is turned on, there still occurs a case where the human body detection device frequently detects or reports.
Therefore, when the obtained current working mode of the human body detection device is the night working mode, the current illumination intensity in a room (namely the current environment) can be detected, and then corresponding operation can be performed according to the detected current illumination intensity.
And step S30, controlling the human body detection device to operate according to the current illumination intensity.
Specifically, whether the current illumination intensity is smaller than or equal to the preset illumination intensity is judged to obtain a judgment result, and then the operation of the human body detection device is controlled according to the judgment result.
The preset illumination intensity can be set according to the current environment, and different preset illumination intensities can be set in different environments. For example, when an infant sleeps in a night room, a night light with weak illumination intensity needs to be turned on so that parents can observe the condition of the infant at night, and at this time, the preset illumination intensity may be set to be relatively high. When a user with poor sleep quality sleeps at night, the user needs a darker sleep environment, and at the moment, the user can set the preset illumination intensity to be relatively low illumination intensity.
And then, judging whether the current illumination intensity of the current environment is less than or equal to the preset illumination intensity set according to the user condition, and controlling the operation of the human body detection device.
In an embodiment, when the human body detection device is in the first operating mode and detects that a human body exists in the current environment, whether to report the detection result that the human body exists in the current environment is determined according to the determination result whether the current illumination intensity of the current environment is less than or equal to the preset illumination intensity.
Specifically, when the current illumination intensity is less than or equal to the preset illumination intensity, the human body detection device is controlled to report the detection result that the human body exists in the current environment.
More specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is less than or equal to the preset illumination intensity, it is indicated that the illumination intensity in the room of the user is the illumination intensity during sleep, and therefore, when a person in the room walks away and is detected by the human body detection device, reporting is needed so as to prompt or warn the user that other persons exist in the room.
And when the current illumination intensity is greater than the preset illumination intensity, controlling the human body detection device not to report the detection result of the human body existing in the current environment.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is greater than the preset illumination intensity, it is indicated that the user in the room is working or watching television, and the like.
In another embodiment, when the current illumination intensity is less than or equal to the preset illumination intensity, the human body detection device is controlled to perform human body detection.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is less than or equal to the preset illumination intensity, it is indicated that the illumination intensity in the room of the user is the illumination intensity during sleep, and therefore, the human body detection device needs to be controlled to perform human body detection so as to prevent a person from entering the room during sleep of the user.
And when the current illumination intensity is greater than the preset illumination intensity, controlling the human body detection device not to carry out human body detection.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is greater than the preset illumination intensity, it indicates that the user in the room is working or watching television. At this time, in order to further save resources, particularly, the power of the power supply battery of the human body detection device, the human body detection device is controlled not to perform human body detection.
In an embodiment, when the current operating mode is the second operating mode and the human body detection device detects that a human body exists in the current environment, the human body detection device is controlled to report a detection result that the human body exists in the current environment.
Specifically, when the obtained current working mode of the human body detection device is the all-day working mode (second working mode), the detection of the illumination intensity of the current environment is not required, and as long as the human body detection device detects a human body, the detection result is reported to the server. To prompt or alert the user that someone has entered the room.
An embodiment of the present invention further provides a human body detection device, as shown in fig. 2, the device includes: a human body detection unit 21, an illumination detection unit 22, and a control unit 23.
The human body detection unit 21 is configured to detect whether a human body exists in the current environment. The human body detection unit 21 is preferably a PIR sensor, but the present application is not limited thereto, and may be other devices capable of detecting a human body.
The illumination detection unit 22 is configured to detect a current illumination intensity within the current environment. The illumination detection unit 22 is preferably an illumination sensor, but the present application is not limited thereto, and may be other devices capable of detecting the illumination intensity.
The control unit 23 is configured to obtain a current working mode, and control the operation of the human body detection unit 21 according to the current illumination intensity when the current working mode is the first working mode.
Specifically, in an embodiment, in order to enable the human body detection device to meet different use requirements of different people, a preset working mode may be performed on the human body detection device.
Specifically, the operation mode may include an all-day operation mode, a night operation mode, and the like. For example, when a person moves in a room for a long time (for example, when the old person lives in a home), the human body detection device is frequently triggered, so that when the human body detection device detects a human body, the server is frequently reported, and further, resources are wasted. When the human body detection device is powered by a battery, the service life of the battery is shortened due to frequent detection or information reporting, and the battery needs to be replaced frequently. Under the condition, the user only needs to perform human body detection after falling asleep, and therefore the working mode only needs to be adjusted to the night working mode. When no person is in the room (if the user needs to work in the daytime), the all-day working mode can be started to ensure that no person monitors the room at home. Of course, the detection device can be used for starting detection when no person exists in a house when the detection device goes out, and closing detection when a person exists in the house, and certainly, the detection device is not limited by the application.
Regarding the preset working mode, the preset working mode can be realized by adding a mode selection unit on the human body detection device, for example, a dial device can be added in the human body detection device, and a user only needs to set the working mode of the human body detection device by the dial mode. The working mode of the human body detection device can be set in a software mode. For example, the operation mode of the human body detection device is set by the mobile phone APP.
In an embodiment, the control unit 23 is configured to determine whether the current illumination intensity is less than or equal to a preset illumination intensity to obtain a determination result, and control the operation of the human body detection unit 21 according to the determination result.
Specifically, when the user turns on the night operation mode (i.e., the first operation mode) of the human body detection device, it cannot be said that no person is moving in the room. For example, during night work or watching television. Therefore, even if the night mode of the human body detection device is turned on, there still occurs a case where the human body detection device frequently detects or reports.
Therefore, when the obtained current working mode of the human body detection device is the night working mode, the current illumination intensity in a room (namely the current environment) can be detected, and then corresponding operation can be performed according to the detected current illumination intensity.
The preset illumination intensity can be set according to the current environment, and different preset illumination intensities can be set in different environments. For example, when an infant sleeps in a night room, a night light with weak illumination intensity needs to be turned on so that parents can observe the condition of the infant at night, and at this time, the preset illumination intensity may be set to be relatively high. When a user with poor sleep quality sleeps at night, the user needs a darker sleep environment, and at the moment, the user can set the preset illumination intensity to be relatively low illumination intensity.
Further, the control unit 23 determines whether the current illumination intensity of the current environment is less than or equal to a preset illumination intensity set according to the user condition, to control the operation of the human body detecting unit 21.
In an embodiment, the control unit 23 is configured to determine whether to report the detection result of the human body existing in the current environment according to a determination result of whether the current illumination intensity of the current environment is less than or equal to the preset illumination intensity when the human body detection device is in the first working mode and the human body detection unit 21 detects that the human body exists in the current environment.
Specifically, when the current illumination intensity is less than or equal to the preset illumination intensity, the control unit 23 reports a detection result that a human body exists in the current environment.
More specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is less than or equal to the preset illumination intensity, it indicates that the illumination intensity in the room of the user is the illumination intensity during sleep, and therefore, when a person in the room moves and is detected by the human body detection unit 21, reporting is needed so as to prompt or warn the user that other persons exist in the room.
When the current illumination intensity is greater than the preset illumination intensity, the control unit 23 does not report the detection result of the human body existing in the current environment.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is greater than the preset illumination intensity, it is indicated that the user in the room is working or watching television, and the like.
In another embodiment, the control unit 23 controls the human body detecting unit 21 to perform human body detection when the current illumination intensity is less than or equal to the preset illumination intensity.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is less than or equal to the preset illumination intensity, it indicates that the illumination intensity in the room of the user is the illumination intensity during sleep, and therefore, the human body detection unit 21 needs to be controlled to perform human body detection to prevent a person from entering the room during sleep of the user.
The control unit 23 controls the human body detecting unit 21 not to perform human body detection when the current illumination intensity is greater than the preset illumination intensity.
Specifically, when the human body detection device is in the night mode and the current illumination intensity in the room is greater than the preset illumination intensity, it indicates that the user in the room is working or watching television. At this time, in order to further save resources, particularly, the power of the power supply battery of the human body detection device, the human body detection unit 21 is controlled not to perform human body detection.
In an embodiment, when the current working mode is the second working mode and the human body detecting unit 21 detects that a human body exists in the current environment, the control unit 23 reports a detection result that a human body exists in the current environment.
Specifically, when the obtained current working mode of the human body detection device is the all-day working mode (second working mode), the detection of the illumination intensity of the current environment is not required, and as long as the human body detection unit 21 detects a human body, the detection result is reported to the server. To prompt or alert the user that someone has entered the room.
In a specific embodiment, as shown in fig. 3, the human body detecting device is a PIR detector, comprising: a PIR sensor 31 (i.e. a human body detection unit), an illumination sensor 32 (i.e. an illumination detection unit), a main control module 33 (i.e. a control unit) and a power supply 34.
That is, the illumination sensor 32 is added to the existing PIR detector to detect the illumination intensity of the current environment.
As shown in fig. 4, the PIR detector may further include a dial switch 35, and the setting of the operating mode of the PIR detector can be realized through the dial switch 35, or certainly, the setting of the operating mode of the PIR detector can also be realized through a software mode, for example, through a mobile phone APP.
As shown in fig. 5, the PIR sensor 31 includes: a probe circuit 311, an amplifier circuit 312, and a comparator circuit 313. The three circuits are conventional circuits of the PIR sensor, and are not described herein again.
The PIR detector of this embodiment can be configured in two operating modes:
all-day working mode
In the all-day working mode, when the PIR sensor 31 detects a person 24 hours in an all-day period, the PIR sensor reports the detected person to the server through the main control module 33 to prompt or warn the user that the person is in the area.
(II) night mode
In night working mode, the PIR probe is started to detect, and only when the ambient light intensity is lower than a certain value (namely the preset light intensity), for example, 30 lux. At this time, the PIR sensor 31 reports when it detects someone.
Further, in order to save more power of the power supply (e.g., battery), the main control module 33 directly turns off the detection of the PIR sensor 31 when the ambient light intensity is lower than a certain value.
In the use process, other sensors such as door and window magnets can be matched for simultaneously monitoring the condition of personnel intrusion in the daytime. For example, door and window magnetic sensors can be protected all day long, and PIR detectors are only used for protection at night.
Of course, if the PIR detector is started to report in the daytime, the all-day mode can be started, and the PIR detector can be used flexibly.
This application only keeps the paster position of illumination sensor 32 even in hardware circuit design, does not paste corresponding device when need not using, can adopt a PCB, has saved PCB's design cost.
The embodiment of the invention also provides a controller, which comprises a memory and a processor, wherein the memory stores a computer program, and the program can realize the steps of the human body detection method when being executed by the processor.
Embodiments of the present invention also provide a computer-readable storage medium for storing a computer program, where the computer program is executed by a computer or a processor to implement the steps of the human body detection method.
The human body detection method and the human body detection device of the embodiment can set various working modes, so that the human body detection device can be more suitable for the current use environment, and the use requirements of personnel under different conditions are met. According to the method and the device, by judging the illumination intensity of the current environment, the human body detection device does not detect the human body or does not report after detecting the human body under the condition that the illumination intensity is large (such as in the daytime), so that the problems of frequent detection or frequent reporting and resource waste of the human body detection device are solved.
