Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and in particular to a big data-based smart building monitoring device. Background Art

[0002] Monitoring devices refer to equipment or systems used to monitor and record the operating status of specific areas, places or systems. They are usually used in a variety of scenarios such as security monitoring, production monitoring, and environmental monitoring. They aim to improve safety, management efficiency, and resource utilization. Through data collection, analysis, and reporting, they help managers and operators to understand and respond to changes and events in the monitored areas in a timely manner, thereby improving efficiency, reducing risks, and supporting intelligent decision-making and predictive analysis.

[0003] The existing patent publication number CN211956199U discloses a smart building monitoring device based on big data, which relates to the technical field of monitoring devices, including a protective shell, a camera is fixedly installed on the inner top wall of the protective shell, a bottom plate is fixedly installed on the bottom surface of the protective shell, and two slide grooves are fixedly installed on the inner side wall of the protective shell, and the two slide grooves are symmetrical, and a protective plate is slidably connected between the two slide grooves. The design structure of the utility model is reasonable. It can be designed through the coordination of the slide groove, protective plate, ejection component, rotating plate, electromagnet and controller. When someone maliciously damages the camera with a stick, the protective shell is vibrated and triggers the control circuit inside the controller, controls the electromagnet to shrink the electric rod of the electromagnet, and ejects the protective plate and the rotating plate to the right through the ejection component, so that the camera can be blocked by the protective plate and the rotating plate inside the protective shell, thereby realizing the protection function of the camera and preventing the camera from being maliciously damaged.

[0004] Although the above patent application effectively protects the camera in the monitoring device, the method of using a protective plate to block the camera directly affects the normal monitoring angle of the camera, and then it is impossible to effectively monitor the vandals below, and thus it is impossible to grasp their movements, which will make it easier to commit crimes.

DETAILED DESCRIPTION

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] Reference Figure 1-Figure 6 A big data-based smart building monitoring device includes a control terminal and an installation box. The control terminal is a computer in the monitoring room. It is a prior art and is a control device with monitoring facilities in existing smart buildings. The installation box consists of a top plate 1, a bottom plate 2, a back plate 3 and two side plates 4. The top plate 1 is used for top installation, and the back plate 3 and the two side plates 4 are used for wall installation, which are used for both installation and protection. The front end of the installation box is open and the front end of the bottom plate 2 is shorter than the top plate 1, providing a sufficient field of view for the monitoring camera 5.

[0030] The installation box is provided with a monitoring mechanism, a protection mechanism, a cleaning mechanism and an infrared sensor mechanism. The monitoring mechanism includes a monitoring camera 5 fixedly installed at the lower end of the top plate 1. The protection mechanism includes a semi-circular limit arc plate 6 fixedly connected to the lower end of the top plate 1. The limit arc plate 6 is provided with a movable groove concentric with it. Two curved glass plates 7 symmetrically arranged on the left and right are slidably connected in the movable groove. The central angles of the two curved glass plates 7 are both 90 degrees. The two curved glass plates 7 can be received in the limit arc plate 6, and the two can be rotated forward and contact each other, thereby forming a whole ring with the limit arc plate 6. It is used to protect the monitoring camera 5. The upper end of the top plate 1 is provided with an arc sliding opening 8 concentric with the curved glass plate 7. The upper front positions of the two curved glass plates 7 are fixedly connected with sliding rods 9. The sliding rods 9 play a limiting role and move with the movement of the curved glass plates 7. The upper ends of the two sliding rods 9 are both slidably passed through the arc-shaped sliding opening 8 and are fixedly connected with contact columns 10. When the front ends of the two curved glass plates 7 are in contact, the two contact columns 10 are also in contact with each other. A second electric telescopic rod 22 is fixedly installed on the upper end of the top plate 1. The telescopic end of the second electric telescopic rod 22 is fixedly connected with a U-shaped limit frame 23. The limit frame 23 is located in the middle and rear position of the arc-shaped sliding opening 8. The second electric telescopic rod 22 can drive the limit frame 23 to move forward, so that it wraps the two contact columns 10 in contact with each other, so that the two cannot move, thereby locking the two curved glass plates 7.

[0031] A cylinder 11 is fixedly passed through the upper end of the bottom plate 2 and is arranged concentrically with the curved glass plate 7. A petal-shaped glass plate 12 is arranged between the cylinder 11 and the two curved glass plates 7. The petal-shaped glass plate 12 is in a quarter bowl shape. The petal-shaped glass plate 12 is fixedly connected to the lower end of the curved glass plate 7 and is in sliding contact with the outer circumference of the cylinder 11. Two rotating rings 13 are rotatably sleeved on the outer circumference of the cylinder 11 and are spaced apart from each other. A connecting block 14 is fixedly connected to the two rotating rings 13. The lower ends of the two connecting blocks 14 are fixedly connected to the two petal-shaped glass plates 12 respectively. The arrangement of the two rotating rings 13 and the connecting block 14 allows the two petal-shaped glass plates 12 to rotate independently. The curved glass plate 7 and the corresponding petal-shaped glass plate 12 together form a protective glass cover. The two protective glass covers can rotate independently, and when the curved glass plate 7 rotates to the front, the front ends of the two petal-shaped glass plates 12 also contact each other to form a half bowl shape. At this time, the protective glass cover can completely wrap the front and lower positions of the surveillance camera 5, effectively protecting the surveillance camera without blocking the surveillance field of view.

[0032] It should be noted that the petal-shaped glass plate 12 and the curved glass plate 7 are both tempered glass and have good impact resistance.

[0033] A first driving mechanism is provided under the base plate 2, and the first driving mechanism includes two right-angle blocks 15 fixedly connected to the upper ends of the two connecting blocks 14. The upper ends of the two right-angle blocks 15 extend to the top of the cylinder 11 and are fixedly connected to connecting columns 16 vertically penetrating the cylinder 11. The two connecting columns 16 are fixedly connected to the first connecting rods 17 at one end located under the base plate 2. The two first connecting rods 17 are symmetrically distributed on the left and right. Through the connecting action of the connecting columns 16, the first connecting rods 17 can rotate synchronously with the corresponding petal-shaped glass plate 12. The ends of the two first connecting rods 17 away from the connecting column 16 are both rotatably connected to the second connecting rod 18. The two second connecting rods 18 are V-shaped and are rotatably connected to the I-shaped block 19 at the ends away from the first connecting rod 17. The first electric telescopic rod 20 is fixedly installed at the lower end of the base plate 2. The telescopic end of the first electric telescopic rod 20 is fixedly connected to the rear end of the I-shaped block 19. The lower end of the base plate 2 is provided with an annular groove 21 arranged concentrically with the cylinder 11. The upper ends of the two first connecting rods 17 are both fixedly connected to a slider sliding in the annular groove 21. The annular groove 21 and the slider play a limiting role, so that the two first connecting rods 17 can stably rotate about the axis of the cylinder 11. Specifically, when the first electric telescopic rod 20 drives the I-shaped block 19 to move forward, the second connecting rod 18 can be used to push the corresponding first connecting rod 17 to rotate forward. The two first connecting rods 17 rotate forward at the same time, which can drive the two protective glass covers to rotate forward, thereby completing the protection of the surveillance camera 5. When the first electric telescopic rod 20 drives the I-shaped block 19 to move backward, the combined protective glass cover can be separated again to release the protection of the surveillance camera 5.

[0034] The infrared sensing mechanism includes two extension rods 24 fixedly connected to the front end of the bottom plate 2 and arranged at intervals on the left and right sides. The extension rods 24 are each provided with an infrared sensor 25 on the opposite side. The infrared sensor 25 is a prior art, which is divided into a transmitting end and a receiving end, and is distributed on the two extension rods 24 to form an infrared network between the two extension rods 24. When an object passes between the two extension rods 24, the infrared sensor 25 can transmit a signal to the control terminal, and then the control terminal can directly control the first driving mechanism to work, so that the protection mechanism can protect the surveillance camera 5. At the same time, the control terminal can determine whether it is malicious damage according to the number of times the signal is received. When the number of received signals exceeds two times, the control terminal will issue an alarm and control the second electric telescopic rod 22 to drive the limit frame 23 to move, wrapping the two contact columns 10, thereby playing the role of locking the protective glass cover, preventing the first driving mechanism from being opened due to human damage, and further improving the protection.

[0035] The cleaning mechanism includes cleaning rods 26 located on both sides of the limiting arc plate 6 and matching the contours of the two protective glass covers. The cleaning rods 26 are provided with bristles at one end close to the protective glass cover, and the bristles are arranged in close contact with the protective glass cover. An arc groove 27 arranged concentrically with the limiting arc plate 6 is provided at the lower end of the top plate 1 and at the outer side of the limiting arc plate 6. The upper ends of the two cleaning rods 26 are slidably connected in the arc groove 27. The ends of the two cleaning rods 26 away from the limiting arc plate 6 are fixedly connected with an arc tooth plate 28 arranged concentrically with the limiting arc plate 6. An arc-shaped slide bar 29 is fixedly connected to the lower position of the arc-shaped tooth plate 28, and two sliding blocks 30 are fixedly connected to the lower ends of the two arc-shaped tooth plates 28. The lower ends of the sliding blocks 30 are slidably connected to the arc-shaped slide bar 29. Under the limiting action of the arc-shaped slide bar 29 and the arc-shaped groove 27, the cleaning rod 26 can stably perform an arc-shaped movement. When the protective glass cover is closed, the cleaning rod 26 can move along the surface of the protective glass cover, thereby cleaning the surface of the protective glass cover, and when the protective glass cover is opened, the cleaning rod 26 can also clean its surface.

[0036] A second driving mechanism is provided on both side panels 4, and the second driving mechanism includes a driving motor 32 fixedly installed on the inner side of the side panel 4. A gear 31 is fixedly sleeved on the output end of the driving motor 32, and the gear 31 is meshed with the arc-shaped toothed plate 28 on the same side. The driving motor 32 can drive the arc-shaped toothed plate 28 to make an arc-shaped motion through the meshing of the gear 31 and the arc-shaped toothed plate 28, and then actively control the corresponding cleaning rod 26 to perform cleaning work.

[0037] A jet pump 33 is fixedly installed at the center of the front end of the top plate 1, and the jet end of the jet pump 33 extends below the top plate 1 and is tilted toward the installation box. Specifically, after the protective mechanism performs protective work, if the monitoring camera 5 captures dirt on the protective glass cover, the second driving mechanism can be controlled by the control terminal to drive the two cleaning rods 26 to move forward to clean the dirt on the surface of the protective glass cover. During the cleaning process, the jet pump 33 can continuously blow air toward the surface of the protective glass cover to assist the cleaning rods 26 to better remove dirt, effectively preventing others from maliciously covering the monitoring camera 5 and ensuring the monitoring effect of the monitoring camera 5.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
