Its main function is to continuously collect optical information within the visual range through image sensors and transmit the signals to the monitoring center to realize real-time monitoring, event tracing and safety warning. Outdoor cameras are usually equipped with protective shells to resist environmental factors such as sunlight and rain.

DETAILED DESCRIPTION
[0021] To make the objectives, technical solutions, and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described below in connection with the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.
[0022] Embodiment, refer to Figures 1-4 A building intelligent security monitoring device, comprising a mounting frame 1, the top of the mounting frame 1 is fixedly connected with a bottom cover 2, the top of the bottom cover 2 is fixedly connected with a top cover 3, the bottom cover 2 and the top cover 3 jointly form an internal cavity for accommodating and protecting internal components. The top of the top cover 3 is fixedly connected with a plurality of arc-shaped arranged spotlights 4, which have a wider light coverage. The end of the top cover 3 is fixedly connected with a first guard plate 5, which plays a role of rain protection. The end of the bottom cover 2 is fixedly connected with a second guard plate 6 for protecting the components on the inner side thereof. The end of the bottom cover 2 is provided with a protective lens 7, the top of the mounting frame 1 is fixedly connected with a first support 11 and a second support 12, further comprising: a surrounding component, the surrounding component is arranged on the second support 12, and the surrounding component is used for circularly moving the camera; a shading component, the shading component is arranged on the first support 11, and the shading component is used for shielding strong light; a cleaning component, the cleaning component is arranged on the bottom cover 2, and the cleaning component is used for removing dirt on the protective lens 7.
[0023] The ring assembly comprises a main shaft 13 rotatably connected to the second support 12 as the central axis of the rotational movement. The main shaft 13 is fixedly connected with a connecting frame 14, and the connecting frame 14 is fixedly connected with the camera 10. The camera 10 can be fixed in the mounting ring of the connecting frame 14 by screws. The main shaft 13 is fixedly connected with a balance frame 15, and the end of the balance frame 15 is fixedly connected with a counterweight 16. The balance frame 15 and the connecting frame 14 are arranged symmetrically at both sides of the main shaft 13. The counterweight 16 installed at the end of the balance frame 15 is used to balance the eccentric mass generated by the camera 10 and its connecting parts, so as to ensure good dynamic balance when the main shaft 13 rotates.
[0024] The second support 12 is fixedly connected with a motor 17 and a gearbox 18. The output end of the motor 17 is in transmission connection with the gearbox 18, and the output end of the gearbox 18 is fixedly connected with the end of the main shaft 13. The gearbox 18 is used for speed reduction and torque increase. The side wall of the second support 12 is fixedly connected with a fixed tube 21, which is sleeved on the main shaft 13. The fixed tube 21 is coaxially arranged with the main shaft 13. The fixed tube 21 is bolted to the second support 12, and there is a gap between the inner hole of the fixed tube 21 and the main shaft 13. The first synchronous wheel 22 is fixedly sleeved on the fixed tube 21. The end of the camera 10 is fixedly sleeved with a connecting cover 23, and the axis of the connecting cover 23 is fixedly sleeved with a second synchronous wheel 24. The first synchronous wheel 22 and the second synchronous wheel 24 are in transmission connection through a synchronous belt. When the main shaft 13 drives the connecting frame 14 and the camera 10 to revolve, the second synchronous wheel 24 and the camera 10 fixedly connected with the second synchronous wheel 24 will generate a reverse rotation movement due to the transmission of the synchronous belt. The final result is that the optical axis direction of the camera 10 can always remain unchanged while revolving around the main shaft 13, only the spatial position is changed.
[0025] It should be noted that the motor 17 is started, and the main shaft 13 is driven to rotate through the gearbox 18. The connecting frame 14 fixed on the main shaft 13 rotates, and the camera 10 on the connecting frame 14 moves together, so that the camera 10 moves in a circle around the axis of the main shaft 13. The camera 10 changes from a fixed spatial coordinate point to a point moving continuously along a circular track. When an external laser or other directional energy tries to irradiate and damage the camera, since the position of the lens of the camera 10 is constantly changing, it is difficult for the attacker to continuously and stably focus the laser beam on the moving target of the lens. The difficulty of aiming and tracking is increased, and the probability of damaging the camera by continuous irradiation of a single point is reduced.
[0026] Reference Figures 4-6The light shielding assembly comprises a driven rod 31 connected with the main shaft 13 through a spline pair. The driven rod 31 is connected with the outer spline at the end of the main shaft 13 through an inner spline, so as to realize power transmission and allow a certain installation freedom in the axial direction. The outer side wall of the annular frame at the top of the first support 11 is fixedly connected with a gear box 32. The driven rod 31 is rotatably connected with the gear box 32 and is supported by a bearing to pass through the gear box 32. The end of the gear box 32 is rotatably provided with a connecting seat 33 fixedly connected with the protective lens 7.
[0027] The protective lens 7 is provided with a filter film. Most of the area of the filter film is dark to attenuate strong light. The filter film is provided with a first light transmission part 34 and a second light transmission part 36. The first light transmission part 34 corresponds to the axial position of the camera 10. The light transmission part is a region with a higher light transmission rate on the filter film. The lens position of the camera 10 is provided with a first detection ring 35 in the form of an annular ring. The second light transmission part 36 corresponds to the axial position of the connecting seat 33. The side of the connecting seat 33 corresponding to the protective lens 7 is provided with a camouflage camera profile. The end of the camera 10 is fixedly connected with a second detection ring 37. The second detection ring 37 is sleeved on the outer side of the annular top of the first support 11. The second detection ring 37 is a larger-diameter annular photoelectric sensor array fixed to the front end of the lens of the camera 10 and surrounds the periphery of the first support 11, and is used for monitoring abnormal light rays incident from a wider angle.
[0028] It should be noted that the first detection ring 35 itself is formed by a plurality of discrete photosensitive elements uniformly distributed and welded along a non-metal annular substrate. These elements collectively form a complete photosensitive ring. The annular substrate is fixed to the lens plastic of the camera 10 through buckling, and is used for monitoring the light intensity directly incident in front of the lens. The output signals of each photosensitive element are collected through a flexible circuit to an analog-to-digital converter. After the light intensity signal is digitized, it is transmitted to the main control unit (such as a microcontroller) of the device. The main control unit can determine whether there is an abnormal strong light incident on the lens by monitoring the mutation of these data in real time (for example, the readings of a certain quadrant or multiple adjacent sensors far exceed the average level of ambient light in a very short time).
[0029] A control signal input end is provided on the internal circuit board of the camera 10. The control signal input end is electrically connected with the image sensor driving circuit or shutter control circuit of the camera 10. The main control unit is connected with the control signal input end. When the main control unit sends a strong light threat signal, a level signal is applied to the control signal input end. The internal circuit of the camera 10 responds to the level signal to drive the image sensor into a protection state. The control signal input end is an expansion pin interface.
[0030] It should be noted that when the main shaft 13 rotates, the driven rod 31 connected by the spline pair rotates synchronously. The first gear 41 at the end of the driven rod 31 drives the rotation of the two second gears 42 in the gear box 32, and the second gears 42 are in meshing with the inner ring gear fixed on the connecting seat 33. The transmission makes the connecting seat 33 and the protective lens 7 installed thereon produce a rotary motion in the opposite direction of the main shaft 13. The light filtering film attached to the protective lens 7 is provided with a first light transmission part 34, which is initially corresponding to the lens of the camera 10. When the protective lens 7 rotates in the opposite direction, the first light transmission part 34 rotates relative to the lens of the camera 10. Only when the two are coincident in angle, the light can pass through the first light transmission part 34 into the lens. This action periodically blocks the continuous light reaching the lens of the camera 10, thereby decomposing the continuous incident light energy in time.
[0031] The annular inner side wall of the first support 11 is fixedly connected with a first bearing 38, the inner ring of the first bearing 38 is fixedly sleeved at the stepped position of the connecting seat 33 and is axially positioned by a circlip, thereby providing stable radial and axial support for the connecting seat 33. The end of the driven rod 31 is fixedly sleeved with a first gear 41, the two sides of the first gear 41 are engaged with second gears 42, the second gears 42 are rotationally connected with the inner side wall of the gear box 32, and the annular inner side wall of the connecting seat 33 is fixedly connected with an inner ring gear, the second gears 42 are in meshing arrangement with the inner ring gear.
[0032] Referring to Figures 7-10 The cleaning assembly comprises a stabilizing groove 51 fixedly connected to the bottom cover 2, the inner side wall of the stabilizing groove 51 is vertically arranged, the horizontal section of the inner wall of the stabilizing groove 51 is rectangularly arranged to provide stable linear guidance. The outer side wall of the bottom cover 2 is fixedly connected with a first fixed frame 52 and a second fixed frame 53, the second fixed frame 53 is fixedly connected with an electric telescopic rod 54 inside, the inner side wall of the first fixed frame 52 is slidingly connected with a valve housing 55, the outer side of the valve housing 55 is provided with a convex strip which cooperates with the groove in the inner side of the stabilizing groove 51 to make it only slide along the length direction of the stabilizing groove 51. The telescopic end of the electric telescopic rod 54 is fixedly connected with a driven frame 56, the end of the driven frame 56 is fixedly connected with the outer side wall of the valve housing 55, the inner wall of the first fixed frame 52 is slidingly connected with a rotating rod 57, the end of the rotating rod 57 is fixedly connected with the end side wall of the driven frame 56.
[0033] The end of the rotating rod 57 away from the driven frame 56 is fixedly connected with a scraping frame 58, and the scraping frame 58 is arranged on the inner side of the second guard plate 6. In the non-working state, the scraping frame 58 and the scraping strip 65 installed thereon are located outside the field of view of the protective lens 7 and are stored in the inner side of the second guard plate 6, so as to avoid blocking the view and deforming due to long-term extrusion.
[0034] The two side walls of the valve housing 55 are fixedly connected with a first one-way valve 61 and a second one-way valve 62, the end of the first one-way valve 61 is arranged in communication with an external water tank, the inner side wall of the valve housing 55 is slidably provided with a plunger rod 63, the top end of the plunger rod 63 is fixedly connected with a pressing block 64, the side wall of the pressing block 64 is in sliding contact with the inner side wall of the stabilizing groove 51, the balancing frame 15 is provided with a pressing portion corresponding to the position of the pressing block 64, the side wall of the scraping frame 58 close to the protective lens 7 is fixedly connected with a scraping strip 65, the side wall of the scraping frame 58 is fixedly connected with a water spraying nozzle 66, the water spraying nozzle 66 is arranged in a hollow strip shape, a plurality of water spraying openings 67 are formed in the side wall of the water spraying nozzle 66 close to the protective lens 7, and a water injection nozzle 68 is arranged on the water spraying nozzle 66 and arranged in communication with the second one-way valve 62.
[0035] The valve housing 55, the plunger rod 63, the pressing block 64 and the two one-way valves jointly constitute a plunger pump. The first one-way valve 61 is a water inlet valve, the outlet of which is connected to the inner cavity of the valve housing 55, and the inlet is connected to the external water tank through a hose, allowing water to flow in but preventing backflow. The second one-way valve 62 is a water outlet valve, the inlet of which is connected to the inner cavity of the valve housing 55, and the outlet is connected to the water injection nozzle 68 through a hose. The plunger rod 63 is in sealing sliding fit with the inner cavity of the valve housing 55. The specific position of the balancing frame 15 is provided with a protrusion as a pressing portion. The scraping strip 65 is made of elastic material such as rubber and is used for scraping the mirror surface.
[0036] An arc-shaped groove 69 is formed in the first fixed frame 52, and a sliding pin 70 is fixedly connected to the rotating rod 57 and is arranged in sliding fit in the arc-shaped groove 69.
[0037] It should be noted that the electric telescopic rod 54 is extended to push the driven frame 56 and the valve housing 55 connected thereto to slide along the stabilizing groove 51. At the same time, the rotating rod 57 moves with the driven frame 56, and the sliding pin 70 thereon slides in the arc-shaped groove 69, so that the scraping frame 58 at the end of the rotating rod 57 swings from the side of the protective lens 7 to the center of the mirror surface, and the scraping strip 65 is attached to the mirror surface. At this time, the pressing block 64 moves to the position below the movement track of the pressing portion of the balancing frame 15. When the motor 17 is started, the main shaft 13 drives the balancing frame 15 to rotate, and the pressing portion thereof presses the pressing block 64 to push the plunger rod 63 to compress the inner cavity of the valve housing 55. The water pressure makes the first one-way valve 61 close and the second one-way valve 62 open, and the clean water is sprayed from the water spraying openings 67 of the water spraying nozzle 66 through the pipeline to be sprayed on the rotating protective lens 7. The rotating mirror surface and the fixed scraping strip 65 rub against each other to scrape off the wet dirt, and the adhering matter on the mirror surface is removed.
[0038] The working principle of the building intelligent security monitoring device is as follows: in the normal camera working state, all moving parts remain stationary. The camera 10 is fixed for monitoring, and the scraping frame 58 and the scraping strip 65 are located at the side of the protective lens 7 and do not contact the mirror surface, so as to avoid deformation caused by long-term extrusion. Figure 11As shown in the top view, the pressing block 64 on the cleaning assembly and the extrusion part on the balance frame 15 are in spatial positions that avoid interference and are not on the same vertical projection line. The second detection ring 37 arranged in a ring shape is in a low-power monitoring standby state with the first detection ring 35 at the lens, and the multiple spotlights 4 at the top are not lit.
[0039] When there is an external threat of using laser irradiation to attempt to damage the camera, the attacker is first easily confused by the camouflage camera profile corresponding to the second light-transmitting part 36 on the protective lens 7. Since the attacker usually needs to remain hidden and hold the laser device at a distance, the light beam is easily offset, so there is a high probability that it will first irradiate the second detection ring 37 arranged on the periphery of the device. After the second detection ring 37 detects an abnormal strong light signal, it transmits the signal to the main control unit of the device. The main control unit then issues an instruction to the camera 10, which immediately closes the electronic shutter to protect the image sensor.
[0040] Subsequently, the main control unit starts the motor 17, which drives the main shaft 13 to start rotating through the gearbox 18. The main shaft 13 drives the camera 10 to move in a circle through the connecting frame 14. The camera 10 is preset with an appropriate rotation speed to minimize the dynamic impact on the imaging quality. Its circular motion causes the lens to continuously change its position in space, reducing the probability of being continuously and stably irradiated by a fixed-direction laser beam. At the same time the camera 10 starts to move, the rotation of the main shaft 13 drives the driven rod 31 to rotate synchronously through the spline pair. The first gear 41 at the end of the driven rod 31 drives the two second gears 42 in the gear box 32 to rotate, and the second gears 42 engage with the internal gear ring on the connecting seat 33, thereby driving the connecting seat 33 and the protective lens 7 thereon to produce a movement opposite to the rotation direction of the main shaft 13. At this time, the light filter and its first light-transmitting part 34 attached to the protective lens 7 also rotate in the opposite direction. The relative motion between the lens of the camera 10 and the first light-transmitting part 34 rotating in the opposite direction causes the lens to receive light only in the short moment when their angles coincide. This relative motion causes the camera 10 to quickly enter a "periodic light-shielding" state from an "optically fully transparent" state. In the light-shielding state, even if there is an instantaneous laser irradiation to the lens, its energy is greatly attenuated. The circular motion of the camera 10 itself (changing the spatial position) and the reverse rotation of the protective lens 7 (changing the light-transmitting timing) cooperate to improve the ability to defend against continuous laser irradiation. At the same time, the main control unit lights up the multiple spotlights 4 arranged in an arc on the top cover 3. The spotlights 4 irradiate the front area, on the one hand, providing supplementary light for the camera 10 in the dynamic light-shielding state, which may reduce the amount of incoming light, to ensure the available clarity of the monitoring picture; on the other hand, the strong light can interfere with the attacker's visual observation and precise aiming behavior, further increasing the difficulty of using laser irradiation to move small-sized camera lenses.
[0041] In the normal maintenance state, the automatic cleaning program can be started regularly. The electric telescopic rod 54 extends and pushes the driven frame 56 to move. The driven frame 56 drives the valve housing 55 to slide along the stable groove 51 and simultaneously drives the rotating rod 57 to move. The sliding pin 70 on the rotating rod 57 slides in the arc-shaped groove 69 of the first fixed frame 52, so that the scraping frame 58 at the end of the rotating rod 57 swings from the position offset from the edge of the protective lens 7 to the working position in which the scraping strip 65 of the scraping frame 58 is attached to the central area of the lens. As shown in Figure 12 the figure, the end of the scraping frame 58 points to the center of the protective lens 7. In this process, the pressing block 64 also moves to the vertical position directly below the pressing part of the balancing frame 15. Then, the motor 17 is started, and the main shaft 13 drives the balancing frame 15 to rotate. When the pressing part on the balancing frame 15 is above the pressing block 64, the pressing block 64 is pressed down. The pressing block 64 pushes the plunger rod 63 down to compress the inner cavity of the valve housing 55. The water pressure makes the first one-way valve 61 close and the second one-way valve 62 open, and the clean water stored in the valve housing 55 is pressed out through the pipe and enters the water injection nozzle 68, and finally is sprayed out from the multiple water injection ports 67 on the side wall of the water injection nozzle 66, and is sprayed on the surface of the protective lens 7 which is rotating in the opposite direction. The sprayed water cooperates with the rotating lens and the fixed scraping strip 65 attached to the lens to remove the dust and other attachments on the lens. The cleaning program uses the rotation of the main shaft 13 as the driving power source of the plunger pump, so that the overall structure is compact, and the water spraying cleaning in the rotating movement of the protective lens 7 is realized. This regular operation mechanism also makes the gear pair and other movement mechanisms in the gear box 32 move, which helps to keep the lubricating oil from drying out due to long-term inactivity, and at the same time can detect potential movement mechanism failures in the early stage, so as to ensure that the core anti-laser rotating function remains stable and reliable.
