Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, an embodiment of the present application provides a sensing device 10, including: the human body induction system comprises a controller 101, an infrared pyroelectric human body induction module 102 and a distance measurement module 103. The controller 101 is electrically connected with the infrared pyroelectric human body induction module 102 and the distance measurement module 103 respectively. That is, the sensing device 10 provided in the embodiment of the present application includes two detection modules, namely, an infrared pyroelectric human body sensing module 102 and a distance measuring module 103.
The infrared pyroelectric human body sensing module 102 is used for collecting human body infrared signals within a detection range. The detection range is determined according to the performance of the infrared pyroelectric human body induction modules 102, for example, the detection range of some infrared pyroelectric human body induction modules 102 is 0-5 m, and the detection range of other infrared pyroelectric human body induction modules 102 is 0-10 m. Referring to fig. 2, structurally, the infrared pyroelectric human body sensing module 102 includes a filter 1021, a pyroelectric detecting element 1022, and a pre-amplifier circuit 1023. In order to prevent the external environment from interfering with the output signal of the module, the above components are vacuum-sealed in a metal enclosure. The filter 1021 of the pyroelectric infrared human body sensor module 102 is a band-pass filter, which is packaged at the top of the housing of the pyroelectric infrared human body sensor module 102 to selectively pass the infrared radiation with specific wavelength, and the infrared radiation reaching the pyroelectric detecting element 1022 outside the cut-off range cannot pass. The pyroelectric detecting element 1022 is a core element of the infrared pyroelectric human body induction module 102, and is manufactured by plating metal electrodes on two sides of a pyroelectric crystal and then applying electric polarization, and is equivalent to a flat capacitor taking the pyroelectric crystal as a dielectric medium. When the infrared light source is irradiated by infrared light with non-constant intensity, the charge density of the surface electrode of the infrared light source is changed due to the generated temperature change, and therefore pyroelectric current is generated. The preamplifier circuit 1023 is composed of a field effect transistor source follower with high internal resistance, and converts a weak current signal of the pyroelectric detector 1022 into a useful voltage signal through impedance conversion and outputs the useful voltage signal to the controller 101.
The distance measurement module 103 is configured to collect a distance to a target.
Optionally, in order to improve the ranging accuracy and effectively acquire the distance to the target in an environment with a poor sight line, in this embodiment, the ranging module 103 employs an ultrasonic ranging module. The principle of ultrasonic ranging is that the propagation speed of ultrasonic waves in the air is known, the time of the sound waves reflected back when encountering a target after being transmitted is measured, and the actual distance from a transmitting point to the target is calculated according to the time difference between transmitting and receiving. Structurally, the ultrasonic ranging module comprises an ultrasonic generating circuit, an ultrasonic receiving and amplifying circuit and a counting and displaying circuit. Since the specific structure of the ultrasonic ranging module is well known to those skilled in the art, it is not described herein.
Optionally, in order to avoid interference of temperature and wind direction in the environment and improve accuracy of ranging, the ranging module 103 may further adopt an optical ranging module, such as a laser range finder or a Time of flight (TOF) ranging module. The present application is not limited thereto.
In the embodiment of the present application, the sensing device 10 includes two status modes, i.e., an unattended status mode and a attended status mode. The unmanned state mode is that the two detection modules do not detect human bodies. When the sensing device 10 is in the unattended mode, the controller 101 sends a first control command to the triggering device connected thereto, so that the triggering device connected thereto is turned off. For example, if the triggering device connected to the controller 101 is an LED (Light Emitting Diode) lamp, the controller 101 sends a first control instruction to the LED lamp when the LED lamp is in the unattended mode, so that the LED lamp is in the off state. Correspondingly, the human state mode is that the detection module detects a human body. When the sensing device 10 is in the unattended mode, the controller 101 sends a second control command to the trigger device connected thereto, so that the trigger device connected thereto is turned on. For example, if the triggering device connected to the controller 101 is an LED lamp, the controller 101 sends a second control command to the LED lamp to turn on the LED lamp when the person is in the person state mode.
The triggering device may also be a speaker, for example, the speaker may not sound when the sensing device 10 is in the unattended mode, and the speaker may sound when the sensing device 10 is in the manned mode. The present application is not limited thereto.
Next, how the sensing device 10 is switched from the unattended state mode to the manned state mode will be described. When the sensing device 10 is in the unattended state mode, the controller 101 is specifically configured to continuously obtain a first signal acquired by the infrared pyroelectric human body sensing module 102; when the first signal is a human infrared signal; acquiring a first distance between the target and the distance measurement module 103; and when the first distance is within the detection range, controlling the sensing device 10 to be in the manned state mode.
That is, when the sensing device 10 is in the unattended mode, the controller 101 may continuously obtain the first signal collected by the infrared pyroelectric human body sensing module 102, when the infrared pyroelectric human body sensing module 102 detects a human body infrared signal, the controller 101 further obtains the first distance between the distance measuring module 103 and the target, and when the first distance is within the detection range, the sensing device 10 is controlled to be in the manned mode. When the first distance is out of the detection range, it indicates that the infrared pyroelectric human body sensing module 102 is triggered by mistake, and at this time, the sensing device 10 is kept in an unmanned state mode.
To sum up, the human body induction by the infrared pyroelectric body induction module 102 and the distance measurement module 103 is completed together in the embodiment of the present application, after the infrared pyroelectric body induction module 102 collects the infrared signal of the human body, the secondary verification is performed by the distance measurement module 103, and when the first distance detected by the distance measurement module 103 from the target is within the detection range, the induction device 10 is switched to the manned state mode. When the sensing device 10 is switched to the manned state mode, if the human body is still after the detection range, the human body in the detection range may be detected based on the distance measuring module 103. Through the mode, the accuracy of triggering the human body sensing event is improved, so that the equipment connected with the human body sensing event can be effectively controlled, the condition of false triggering is reduced, the service life of the whole system is prolonged, and the user experience is enhanced.
Next, how the sensing device 10 is switched from the manned state mode to the unmanned state mode will be described. When the sensing device 10 is in the manned state mode, the controller 101 is specifically configured to continuously obtain a second distance from the target, which is detected by the ranging module 103; when the second distance is not within the detection range, acquiring a second signal acquired by the infrared pyroelectric human body induction module 102; when the second signal is a non-human infrared signal, the sensing device 10 is controlled to be in the unmanned state mode.
That is, when the sensing device 10 is in the unattended mode, the controller 101 may continuously obtain the second distance between the sensing device and the target, which is detected by the distance measuring module 103, and when the second distance is not within the detection range, the controller 101 further obtains the second signal collected by the infrared pyroelectric human body sensing module 102; when the second signal is a non-human infrared signal, the sensing device 10 is controlled to be in the unmanned state mode. When the second signal is a human infrared signal, the distance measuring module 103 is triggered by mistake, and the sensing device 10 is kept in the manned state mode.
In summary, in the embodiment of the application, the infrared pyroelectric human body induction module 102 and the ranging module 103 jointly complete induction on the human body, and when the ranging module 103 detects that the second distance from the target is not within the detection range, the second signal acquired by the infrared pyroelectric human body induction module 102 is acquired; when the second signal is a non-human infrared signal, the sensing device 10 is switched to the unattended mode. Through the method, the accuracy of triggering the human body induction event is improved, the condition of false triggering is reduced, the service life of the whole body is prolonged, and the user experience is enhanced.
Optionally, the sensing device 10 further comprises a power module. The power module is electrically connected with the infrared pyroelectric human body induction module 102, the distance measurement module 103 and the controller 101 respectively. The power module is used for supplying power to the infrared pyroelectric human body induction module 102, the distance measurement module 103 and the controller 101.
Referring to fig. 3 as another power supply method, optionally, the sensing device 10 further includes a power management module 105 in addition to the power module 104. The power management module 105 is electrically connected with the infrared pyroelectric human body induction module 102, the distance measurement module 103, the power module 104 and the controller 101 respectively.
The power module 104 is configured to supply power to the power management module 105, the power management module 105 is configured to supply power to the controller 101, continuously supply power to the infrared pyroelectric human body sensing module 102 when the sensing device 10 is in the unattended state mode, and supply power to the ranging module 103 when the first signal is a human body infrared signal.
The power management module 105 may be a power management chip. Power Management chips (Power Management Integrated Circuits) are chips that take on the responsibility of transforming, distributing, detecting and other Power Management in electronic device systems. The CPU power supply amplitude is mainly identified, corresponding short moment waves are generated, and a post-stage circuit is pushed to output power. In the embodiment of the present application, the power management chip may be, but IS not limited to, HIP6301, IS6537, RT9237, ADP3168, KA7500, and TL 494.
That is, when induction system 10 is in the unmanned state, at this moment, controller 101 is the first signal that acquires infrared heat release electricity human body induction module 102 earlier and detects, so in order to avoid this in-process range module 103 still to be in operating condition and cause unnecessary waste, consequently, when induction system 10 is in the unmanned state, last supplying power for infrared heat release electricity human body induction module 102, only when first signal is human infrared signal, power management module 105 receives the instruction back to the range module 103 power supply that controller 101 sent, just supplies power to range module 103.
Correspondingly, the power management module 105 may be further configured to continuously supply power to the distance measurement module 103 when the sensing device 10 is in the manned state mode, and supply power to the infrared pyroelectric human body sensing module 102 when the distance measurement module 103 detects that the second distance to the target is within the detection range.
That is, when the sensing device 10 is in the manned state, at this moment, the controller 101 firstly obtains the second distance between the sensing module 103 and the target, so as to avoid unnecessary waste caused by the fact that the infrared pyroelectric human body sensing module 102 is still in the working state in the process, therefore, when the sensing device 10 is in the manned state, the power is continuously supplied to the sensing module 103, and only when the sensing module 103 detects that the second distance between the sensing device and the target is not in the detection range, the power is supplied to the infrared pyroelectric human body sensing module 102.
Referring to fig. 4, based on the same inventive concept, an embodiment of the present invention further provides an electronic apparatus 100, which includes a triggering device 20 and the sensing device 10 electrically connected to the triggering device 20.
In the embodiment of the present application, the triggering device 20 is an advertisement screen. The advertising screen is electrically connected to the controller 101 in the sensing device 10. When the sensing device 10 is in the unattended state, the advertisement screen is in the closed state, and when the sensing device is in the manned mode, the advertisement screen is in the open state. That is, after the controller 101 acquires the human body infrared signal collected by the infrared pyroelectric human body sensing module 102, it also acquires that the first distance to the target detected by the distance measuring module 103 is within the detection range, and controls the sensing device 10 to be in the manned state mode. And at this time, the controller 101 transmits a second control command to the advertisement screen to cause the advertisement screen to be opened. When the controller 101 acquires that the second distance to the target detected by the distance measurement module 103 is not within the detection range, and also acquires that the second signal acquired by the infrared pyroelectric human body sensing module 102 is a non-human body infrared signal, the sensing device 10 is controlled to be in the unmanned state mode. At the moment, a first control instruction is sent to the advertising screen, so that the advertising screen is in a closed state.
As an embodiment of disposing the infrared pyroelectric human body sensing module 102 and the distance measuring module 103, referring to fig. 5, the electronic device 100 further includes a sensing board 30, and the sensing board 30 is disposed at the bottom of the advertisement screen 21. The infrared pyroelectric human body induction module 102 and the distance measurement module 103 are arranged on the induction plate 30.
Optionally, for convenience of detection, the included angle between the sensing board 30 and the horizontal plane is in the range of (0, 90 °), for example, the included angle between the sensing board 30 and the horizontal plane is 30 ° and 40 °, and the present application is not limited thereto.
Of course, in other embodiments, the electronic device 100 may also be directly attached to a wall, and the application is not limited thereto.
