Description
TECHNICAL FIELD

[0002] The induction detection device using the sensor of passive infrared detection is used for automatically detecting whether a person enters the detection range of the sensor, and the induction detection device is used in combination with a lighting monitoring system. When the sensor detects that no person enters the detection range, the induction detection device sends a no-person-entering signal to the monitoring system, and then the monitoring system controls the lighting lamp to be powered off. When the sensor detects that a person enters the detection range, the induction detection device sends a person-entering signal to the monitoring system, and then the monitoring system controls the lighting lamp to be powered on for lighting.
[0003] In many lighting application scenarios, in the detection range covered by the sensor, there is a part of the range that does not need to be detected by the user.

[0040] like Figures 1 to 4 As shown, according to a first aspect of this application, the sensing and detection device provided in the embodiments of this application includes a housing 10, an electrical component 20, a lens 30, and a shield 40. The housing 10 has a receiving space 11. The electrical component 20 is disposed within the receiving space 11. The electrical component 20 includes a circuit board 21 and a sensor 22 and an infrared receiver 23 electrically connected to the circuit board 21. Both the sensor 22 and the infrared receiver 23 extend to the outside of the receiving space 11. The sensor 22 is used to receive low-frequency signals, and the infrared receiver 23 is used to receive high-frequency signals for debugging. The lens 30 is mounted on the housing 10 and covers the sensor 22 and the infrared receiver 23. The shield 40 is connected to the housing 10 and covers at least a portion of the lens 30. The shield 40 has a detection window 41 and a plurality of signal through holes 42 located around the detection window 41. The detection window 41 is provided corresponding to the lens 30, and the signal through holes 42 are configured to block low-frequency signals and allow high-frequency signals to pass through.
[0041] The sensing and detection device of this application is installed at the high ceiling of an indoor space to detect a predetermined area within the room. In this sensing and detection device, a shielding cover has a detection window 41 through which both low-frequency signals (i.e., low-frequency infrared signals from the human body) and high-frequency signals used for debugging can be transmitted to the lens 30. The low-frequency infrared signals from the human body are then received by the sensor 22, and the high-frequency signals used for debugging are received by the infrared receiver 23. Furthermore, the shielding cover 40 also has multiple signal passage holes 42 located around the detection window 41. These signal passage holes 42 are used to block low-frequency infrared signals from the human body while allowing high-frequency signals used for debugging to pass through. Thus, the range through which the shielding cover 40 allows high-frequency signals to pass is larger than the range through which low-frequency infrared signals from the human body can pass. The high-frequency signals can be transmitted through the detection window 41 and the multiple signal passage holes 42 to the lens 30 for signal amplification and then received by the infrared receiver 23, thereby better completing the debugging work. Furthermore, the signal is blocked by the hole 42 from being transmitted from the human body to the sensor 22. The human body low-frequency infrared signal can only be transmitted through the detection window 41 to the lens 30 to amplify the signal and then to the sensor 22, thus achieving the purpose of blocking the area that does not need to be detected in the detection range of the sensor 22.
[0042] The human body low-frequency infrared signal refers to low-frequency infrared radiation, belongs to far infrared, is a low-energy electromagnetic wave radiation, and the wavelength is 25-1500 μm. The corresponding frequency range can be obtained through the relationship between the wavelength and the frequency Calculation, wherein the speed of light c is about 3*108m / s, and λ is the wavelength. The human body infrared radiation belongs to low-frequency infrared radiation, that is, the human body low-frequency infrared signal. In the embodiments of the present application, the low-frequency signal can be the human body low-frequency infrared signal, and can also be other low-frequency wave signals. Hereinafter, the human body low-frequency infrared signal is taken as an example for description.
[0043] In the embodiments of the present application, the high-frequency signal can be a high-frequency infrared signal, and the high-frequency infrared signal refers to high-frequency infrared radiation, belongs to near infrared, and is a high-energy high-frequency electromagnetic wave radiation of 0.75-3 μm. In addition, the high-frequency signal of the present application can also be other high-frequency wave signals. Hereinafter, the high-frequency infrared signal is taken as an example for description.
[0044] In some embodiments of the present application, the sensor 22 of the sensing detection device includes but is not limited to a passive infrared sensor, referred to as a PIR sensor, and the lens 30 correspondingly adopts a passive infrared sensor lens, referred to as a PIR lens. The PIR sensor is a non-contact sensor based on pyroelectric effect, which can detect the infrared radiation changes emitted by warm-blooded organisms such as human bodies and animals, and determine whether an object (such as a human body) is moving by sensing the temperature change of infrared radiation in the environment. Correspondingly, the PIR lens is a key optical element in the PIR sensor system, which is mainly used to enhance the detection capability and sensitivity of the sensor.
[0045] In some embodiments of the present application, the sensor 22 can also adopt an optical sensor, such as an infrared optical sensor, a TOF sensor (TOF is the abbreviation of Time of Flight), a camera, etc. At this time, the lens 30 correspondingly adopts an optical lens.

In order to make the detection window 41 better avoid the top of the spherical cap-shaped lens 30, the middle position of the detection window 41 is expanded into an arc-shaped edge, and at this time, the spherical cap top of the lens 30 can be embedded on the arc-shaped edge. And a plurality of signal passing holes 42 are respectively arranged on both sides of the extension direction of the detection window 41.
[0047] In some embodiments of the present application, as shown in Figure 5 and Figure 6As shown in the figure, the plurality of signal passing holes 42 on the shielding cover 40 are arranged in an array. And, in the longitudinal and transverse directions, the spacing between adjacent two signal passing holes 42 is equal, that is, the plurality of signal passing holes 42 are uniformly distributed.
[0048] In some embodiments of the present application, as shown in the figure, Figure 5 and Figure 6 As shown in the figure, the plurality of signal passing holes 42 on the shielding cover 40 are symmetrically arranged relative to the middle surface 100 parallel to the extension direction of the detection window 41. That is, the number and distribution of the signal passing holes 42 on both sides of the detection window 41 are the same, so that the performance of allowing the passage of the high-frequency infrared signal for debugging while blocking the passage of the low-frequency infrared signal of the human body is the same, thereby being able to more accurately and quickly complete the debugging work.
[0049] In the embodiments of the present application, the aperture of the signal passing hole 42 on the shielding cover 40 is 0.5mm-1.5mm. Preferably, the aperture of the signal passing hole 42 on the shielding cover 40 is about 1.0mm, which can allow the passage of the high-frequency infrared signal, thereby maintaining the receiving debugging function of the infrared receiver 23, but can block most of the low-frequency infrared signal. And, even if the shielding cover 40 is rotated at any angle relative to the shell 10, the function of the infrared receiver 23 receiving the high-frequency infrared signal can be maintained.

And, the second shell 120 is provided with a first through hole 12 and a second through hole 13, the sensor 22 is arranged in the first through hole 12, and the infrared receiver 23 is arranged in the second through hole 13, that is, the sensor 22 and the infrared receiver 23 are respectively arranged outside the accommodation space 11 from the first through hole 12 and the second through hole 13. The shielding cover 40 is detachably connected to the second shell 120, and the lens 30 is provided with a circumferential mounting plate 31, and the circumferential mounting plate 31 is clamped between the circumferential edge of the second shell 120 and the circumferential edge of the shielding cover 40.
[0051] As shown in the figure, Figure 3 and Figure 4As shown, the inner wall of the first shell 110 is provided with a first clamping part 111, the second shell 120 is provided with a second clamping part 121 and a third clamping part 122, the shielding cover 40 is provided with a fourth clamping part 43, the first clamping part 111 and the second clamping part 121 are detachably clamped, and the third clamping part 122 and the fourth clamping part 43 are detachably clamped. In the induction detection device of the present application, the first shell 110 and the second shell 120, and the second shell 120 and the shielding cover 40 are assembled by the clamping mode which is convenient to assemble and convenient to disassemble, so that the assembly efficiency can be improved. Moreover, when the electronic elements of the electrical assembly 20 of the induction detection device need to be repaired due to failure, the shielding cover 40, the first shell 110 and the second shell 120 can be conveniently disassembled and separated by the staff, so that the repair work is convenient, and thus the whole induction detection device does not need to be replaced, which is beneficial to save cost.
[0052] As shown, Figures 1 to 4 The first shell 110 is provided with an electric wire 51, and the electric wire 51 extends into the accommodation space 11 and is electrically connected to the circuit board 21. The electric wire 51 is used for electrically connecting to an external power supply to provide power for the induction detection device.

In the induction detection device of the present application, the third shell 130 serves as a surface shell covering the second shell 120, so that the appearance of the induction detection device is neat and simple. Moreover, as shown, Figure 4 The outer wall of the first shell 110 is provided with a fifth clamping part 112, the third shell 130 is provided with a sixth clamping part 132, and the fifth clamping part 112 and the sixth clamping part 132 are detachably clamped.

Moreover, the first shell 110 and the third shell 130 are sealed by the O-shaped sealing ring 52, so as to realize the dustproof and waterproof performance, and better protect the circuit board 21 arranged in the accommodation space 11.

Wherein, the lighting lamp comprises a lighting light source part and the aforementioned sensing detection device, and the driving device of the lighting light source part is electrically connected with the sensing detection device.
[0055] When a person walks into the detection range of the sensing detection device, the infrared radiation emitted by the human body is detected by the sensor 22 after being enlarged by the lens 30, and then the sensor 22 sends a signal to the control circuit of the circuit board 21 that a person is walking, so that the control circuit of the circuit board 21 controls the indoor lighting lamp to be powered on for lighting, which is convenient for the activities of the personnel in the room. When the personnel leave the room, the sensor 22 does not detect the infrared radiation of the human body continuously within a predetermined time, and then the control circuit of the circuit board 21 controls the lighting lamp to be powered off to be closed, thereby achieving the purpose of energy saving and power saving.
