In the design, the intelligent monitoring equipment can be one part of an intelligent monitoring network system and also can be an intelligent doorbell for the Internet of things.

Referring to fig. 1 and 2, the housing 1 includes a rear shell 11, a middle frame 12 fixed in front of the rear shell 11, a panel 13 fixed in front of the middle frame 12, and a mounting plate 14 fixed in back of the rear shell 11. An opening-shaped accommodating cavity 110 is formed in the front of the rear case 11, and the monitoring module 2, the camera module 3, the infrared lamp module 4, the speaker module 5, the microphone module 6 and the key module 7 are installed in the accommodating cavity 110. The middle frame 12 is substantially plate-shaped and is used for covering the opening in front of the rear shell 11, and assisting in fixing and supporting the monitoring module 2, the camera module 3, the infrared lamp module 4, the horn module 5 and the key module 7. A plurality of windows 120 are formed in the middle frame 12 in a penetrating mode and used for matching with the corresponding monitoring module 2, the camera module 3, the infrared lamp module 4, the horn module 5 and the key module 7 in the abdicating mode. The periphery of the middle frame 12 is sleeved with a middle frame sealing ring 121 (located between the matching surfaces of the middle frame 12 and the rear shell 11) for waterproof sealing. The panel 13 is correspondingly attached and fixed on the front surface of the middle frame 12, waterproof adhesive layer materials such as sealant are arranged between the panel 13 and the middle frame 12, the panel 13 mainly plays a role of an appearance piece and has a sealing waterproof effect.

Referring to fig. 1 to 3, the monitoring module 2 is fixed to the middle frame 12, the camera module 3, the infrared lamp module 4, the speaker module 5 and the key module 7 are all fixed to a circuit board 8, and the circuit board 8 is accommodated in the accommodating cavity 110 and fixed to the rear housing 11.

Referring to fig. 2 to 4, the monitoring module 2 includes a sensor support 21, an infrared sensor 22 assembled and fixed on the sensor support 21, and a lens 23. The lens 23 is correspondingly mounted on one of the windows 120 of the middle frame 12. The infrared sensor 22 in this design is preferably a pyroelectric infrared sensor, wherein the lens 23 is actually a fresnel lens, and the lens 23 has two functions: firstly, focusing, namely refracting the pyroelectric infrared signals on the pyroelectric infrared sensor; secondly, the interior of the detection area is divided into a plurality of bright areas and dark areas, so that moving objects (people) entering the detection area can generate variable pyroelectric infrared signals on the pyroelectric infrared sensor in a temperature change mode. The output signal is used for feeding back to a control module (not labeled) of the intelligent monitoring device, and is matched with the communication module to realize further processing control functions (for example, controlling the speaker module 5 to give an alarm and/or notifying a user through the communication module (which may be feedback and operation on a mobile phone of the user through a wireless communication technology)).

The intelligent monitoring device in this design is provided with two infrared sensors 22 arranged side by side, and the two infrared sensors 22 correspond to the same window 120 (shown in fig. 3 and 4). For the sake of convenience of description of the principle, the monitoring module 2 of the intelligent monitoring device of the present design is shown by the model diagrams shown in fig. 4-1 to 4-4, which respectively show 5 different positions and angle states of the infrared sensor 22. The infrared sensor 22 includes a first infrared sensor a and a second infrared sensor B. The infrared sensor 22 in this design can achieve a 120 degree angle monitoring range.

Referring to fig. 4-1, it is shown that the first infrared sensor a and the second infrared sensor B are both horizontally disposed (in the direction of the dotted line, i.e., in the left-right direction). Wherein the leftmost monitoring boundary of the first infrared sensor a is a1, and the rightmost monitoring boundary is a 2. Wherein the leftmost monitoring boundary of the second infrared sensor B is B1 and the rightmost monitoring boundary is B2. The left and right monitoring boundaries of the monitoring module 2 when the first infrared sensor a and the second infrared sensor B are used simultaneously are a1 to B2. The actual monitoring angle of the monitoring module 2 is still in the 120 degree range of a1 to b2, regardless of factors such as refraction of the lens 23 (fresnel lens) assembled on the window 120.

Referring to fig. 4-2, it is shown that the first infrared sensor a 'and the second infrared sensor B' are disposed in an inverted-splayed inclined manner, i.e. inclined at an angle β with respect to the left-right direction shown in fig. 4-1. At this time, the leftmost monitor boundary of the first infrared sensor a 'is a 1', the rightmost monitor boundary is a2 ', the leftmost monitor boundary of the second infrared sensor B' is B1 ', and the rightmost monitor boundary is B2'. When the first infrared sensor a 'and the second infrared sensor B' are used simultaneously, the left and right monitoring boundaries of the monitoring module 2 are B1 'to a 2', and the monitoring angle between B1 'and a 2' is 120 degrees plus twice the β angle by geometric relationship. It is apparent that the monitoring angle between b1 'and a 2' is greater than the monitoring angle between a1 and b 2. Therefore, the monitoring angle of the monitoring module 2 of fig. 4-2 is larger than the monitoring angles between a1 and b2 of fig. 4-1, regardless of refraction of the lens 23 (fresnel lens) assembled on the window 120, and the like.

Referring to fig. 4-3, in practice, the first infrared sensor a "and the second infrared sensor B" are moved to both sides respectively on the basis of fig. 4-2 until the first infrared sensor a "and the second infrared sensor B" are respectively located right behind two edges of the window 120. In this case, the actual monitoring angle range of the monitoring module 2 is also b1 "to a 2", i.e. also 120 degrees plus twice the β angle. It is clear that the monitoring angle between b1 "to a 2" is still larger than the monitoring angle between a1 to b 2. Therefore, the monitoring angle of the monitoring module 2 of fig. 4-3 is larger than the monitoring angles between a1 and b2 of fig. 4-1, regardless of refraction of the lens 23 (fresnel lens) assembled on the window 120, and the like.

Referring to fig. 4-4, in practice, the tilt angles of the first infrared sensor a '"and the second infrared sensor B'" are further increased on the basis of fig. 4-3. Until the leftmost monitoring boundary a1 '″ of the first infrared sensor a is perpendicular to the left-right direction (that is, the leftmost monitoring boundary a 1' ″ of the first infrared sensor a is located at the leftmost edge of the window 120); meanwhile, the rightmost monitoring boundary B1 '"of the second infrared sensor B'" is also perpendicular to the left-right direction (i.e., the rightmost monitoring boundary B1 '"of the second infrared sensor B'" is located at the rightmost edge of the window 120). At this time, the actual monitoring angle range of the monitoring module 2 is a2 "'to b 2"'. However, as shown in connection with fig. 4-3, it can be easily found that the monitoring angle between a2 '"and b 2'" is actually equal to the monitoring angle between b1 "and a 2" in fig. 4-3. The monitoring angle between a2 "'to b 2"' is therefore also greater than the monitoring angle between a1 to b 2. Therefore, the monitoring angle of the monitoring module 2 of fig. 4-3 is larger than the monitoring angles between a1 and b2 of fig. 4-1, regardless of refraction of the lens 23 (fresnel lens) assembled on the window 120, and the like. In combination with the design, the monitoring angle of the single infrared sensor 22 is 120 degrees, which can be easily calculated, and the first infrared sensor a '"and the second infrared sensor B'" in fig. 4-4 are actually inclined by 60 degrees. It follows that in other embodiments, for example, when the monitoring angle of the single infrared sensor 22 is α, in the embodiment shown in fig. 4-4, the actual tilt angle of the corresponding first infrared sensor a '"and second infrared sensor B'" is one-half α.

Referring to fig. 4-5, the first infrared sensor a "" and the second infrared sensor B "" are further tilted with respect to the tilt angles shown in fig. 4-4. At this time, the actual monitoring angle range of the first infrared sensor a "" is a1 "" to a2 "" (here, a2 "", that is, a2 '"in fig. 4 to 4), and the actual monitoring angle range of the second infrared sensor B" "is B1" "to B2" "(here, B2" ", that is, B2'" in fig. 4 to 4), respectively. This obviously creates a dead zone within the section where a1 "" and b2 "" extend and intersect. However, because the actual monitoring distance of the single infrared sensor 22 is limited (generally, 6 to 10m), a1 "" and B2 "" extend and intersect within the actual monitoring distance range of the two infrared sensors 22 to generate a blind area, and therefore, through experimental tests, in the case of the embodiment in the design, under the condition that the inclination angles of the first infrared sensor a "" and the second infrared sensor B "" are not more than 70 degrees, the blind area does not occur within the actual monitoring distance range of the two infrared sensors 22.

As analyzed by the above embodiments of fig. 4-1 to 4-5, when the effective monitoring angle of the single infrared sensor 22 is 120 degrees, the first infrared sensor a and the second infrared sensor B of the present design are obliquely placed in an inverted eight shape, and the range of the inclination angle β is in the range of 0 degree to 70 degrees (preferably 20 degrees to 70 degrees in the present design), the actual monitoring angle of the monitoring module 2 is greater than the actual monitoring angle of the single infrared sensor 22. From this calculation, it is easy to find that, in the case of not considering the actual monitoring distance of the single infrared sensor 22, a general case is that when the effective monitoring angle of the single infrared sensor 22 used is α, and when the first infrared sensor a and the second infrared sensor B are placed in an inverted-eight-character-shaped inclination and the inclination angle β range is in the range of 0 degree to one-half α angle, the actual monitoring angle of the monitoring module 2 is greater than the actual monitoring angle α of the single infrared sensor 22 used.

It should be understood that the designs of fig. 4-1 through 4-5 and all of the possible scenarios in the description are based on the actual effective monitoring angle of the single infrared sensor 22 being used being no less than 90 degrees.

Referring to fig. 2, 3, 5 and 6, the intelligent monitoring device further includes a reset switch assembly 9, where the reset switch assembly 9 includes a reset switch 91 fixed to the circuit board 8, a reset elastic sheet 92 engaged with the reset switch 91, a reset pressing plate 93 and a reset pressing member 94.

The reset pressing plate 93 is located right behind the reset spring 92, and includes a main body portion 931, an extending portion 932, and a connecting portion 933 for connecting the main body portion 931 and the extending portion 932. The body portion 931 is fixed to the rear case 11 by bolts, a through hole 934 is formed at a middle position of the body portion 931, and the reset pressing member 94 is located at the position of the through hole 934 so as to be restrained between the reset pressing plate 93 and the rear case 11. In this design, the reset pressing member 94 and the elastic member 923 are actually made of silica gel material with high elasticity.

This design is through designing into the shell fragment 92 that resets and connecting the pressing plate 921 and the fixed end piece 922 structure of making by the metal material by elastic component 923, so can guarantee that the pressing plate 921 of shell fragment 92 that resets can have sufficient rigidity for the shell fragment 92 that resets is being pressed the overall process, and most deformation takes place on elastic component 923, thereby prevents that the metal part of shell fragment 92 that resets from taking place plastic deformation. In addition, in this design, the pressing piece 921 is designed to be longer, and the fixing end piece 922 is designed to be shorter, that is, the elastic member 923 is located at a position close to the fixing bolt of the reset elastic piece 92, and when the elastic member is used, the pressing piece 921 serves as an operation portion (directly presses the pressing piece 921), so that the elastic deformation amount of the metal part structure of the reset elastic piece 92 can be effectively reduced. Preventing the reset spring 92 from being plastically deformed.

In this design, the extension 932 of the reset pressing plate 93 is attached to a chip (not labeled) on the circuit board 8 for passive heat dissipation of the chip, and the main body 931 is located right above the reset elastic sheet 92, and on the one hand, the main body is used for limiting and fixing the reset pressing member 94, and meanwhile, the main body can play a certain limiting role in the reset elastic sheet 92. An operation hole (not labeled) is formed at the position of the rear shell 11 corresponding to the through hole 934. In use, a user firstly inserts a tool (needle) into the operation hole of the rear shell 11 and presses against the reset pressing member 94, the reset pressing member 94 deforms and presses against the pressing sheet 921 through the through hole 934 of the reset pressing plate 93, and the free end of the pressing sheet 921 presses the reset switch 91 downwards to realize the reset function.
