Description

Technical Field

[0001] This invention relates to the field of base station video surveillance technology, specifically to an intelligent video surveillance system for monitoring base stations. Background Technology

[0002] The base station remote video monitoring system consists of two parts: anti-theft alarm and video monitoring. Utilizing the different characteristics of these two systems, they are organically combined. The anti-theft detector and camera work together to achieve automatic alarm recording and video uploading, implementing closed-loop management of the entire base station. This achieves real-time monitoring and effective management of the base station. It can conduct remote monitoring via wireless networks such as 3G and 2G. The video monitoring part mainly uses cameras to record images. Early cameras were mostly fixed, resulting in large blind spots due to their single shooting direction. Therefore, cameras with adjustable orientation were developed, which automatically adjust their trajectory to enhance the monitoring area of ​​a single camera. For example, Chinese utility model patent CN209218243U discloses a video monitoring device for a communication base station. Its structure includes a fixed platform, a power supply, a monitoring probe mounting shell, a monitoring probe mounting base, a monitoring probe, and a protection mechanism. The power supply is provided on the top surface of the fixed platform, and the monitoring probe mounting shell is welded to the bottom of the angle adjustment mechanism.

[0003] While adjusting the angle can slightly increase the monitoring position of a single camera, its limitations remain significant, only increasing the monitoring area by about 2 times. In addition, the budget for the number of monitoring cameras in a typical server room is limited, and most can only be concentrated in the central position. This means that images in the corners cannot be captured, making them easy for criminals to avoid. Furthermore, as in the case mentioned above, adding cameras with rotating structures, although slightly increasing the shooting range, mostly uses motors in the transmission structure. This makes it difficult to disassemble and reassemble the motor or replace the camera itself when maintenance is needed, which is not conducive to subsequent maintenance work.

[0004] Therefore, we propose an intelligent video surveillance system for monitoring base stations to solve the above problems. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figure 1-5 This invention provides a technical solution: an intelligent video surveillance system for monitoring base stations, comprising a centralized monitoring center, multiple base station field monitoring subsystems, and a base station equipment room 1. The base station field monitoring subsystems include an indoor monitoring module 2, an outdoor monitoring module 3, a base station monitoring host 4, and a wireless transmission unit 5. The indoor monitoring module 2 and the outdoor monitoring module 3 are connected to the base station monitoring host 4, the base station monitoring host 4 is connected to the wireless transmission unit 5, and the wireless transmission unit 5 is connected to the centralized monitoring center. The indoor monitoring module 2 and the outdoor monitoring module 3 collect images and noise information, and the wireless transmission unit 5 transmits the image signals to the centralized monitoring center for real-time monitoring.

[0034] The indoor monitoring module 2 includes two mounting plates 21 fixed to both sides of the top surface inside the base station equipment room 1 and four microphones 25 fixed to the four corners of the top surface of the base station equipment room 1. Multiple horizontal plates 22 are evenly fixed to the bottom surface of the two mounting plates 21. The horizontal plates 22 are perpendicular to the mounting plates 21. A first T-shaped groove 221 is opened on the bottom surface of the horizontal plate 22. A first T-shaped slider 222 is slidably connected in the first T-shaped groove 221. The monitoring camera assembly 24 is fixed to the bottom surface of the first T-shaped slider 222.

[0035] One of the mounting plates 21 has a transmission chamber 23 fixedly connected to one side of its bottom surface. The side wall of the transmission chamber 23 contacts the ends of multiple horizontal plates 22. A dual-axis reduction motor 231 is fixedly connected inside the transmission chamber 23. Two shafts 232 are fixedly connected to the shaft end of the dual-axis reduction motor 231. The shafts 232 are located at the same horizontal position of multiple horizontal plates 22 and are respectively fixedly sleeved with multiple active bevel gears 233. A first reciprocating screw 223 is rotatably connected inside the first T-shaped slide groove 221. A first threaded sleeve 224 is fixedly connected inside the first T-shaped slider 222. The first reciprocating screw 223 meshes with the first threaded sleeve 224. Through the meshing action of the first reciprocating screw 223 and the first threaded sleeve 224, the first T-shaped slider 222 can be driven to move laterally when the first reciprocating screw 223 rotates.

[0036] The first reciprocating screw 223 passes through the side wall of the horizontal plate 22 and is fixed to the first splined shaft 225 at one end near the transmission chamber 23. The side wall of the transmission chamber 23 is located at the same horizontal position of multiple horizontal plates 22 and is rotatably connected to multiple sub-shafts 234. One end of the sub-shaft 234 is located inside the transmission chamber 23 and is fixed to the driven bevel gear 235, and the other end is located outside the transmission chamber 23 and has a horizontally formed first spline groove 236. The first splined shaft 225 is inserted into the first spline groove 236. The driving bevel gear 233 meshes with the driven bevel gear 235. By using the driving bevel gear 233 meshing with the driven bevel gear 235, the rotation of the shaft 232 can drive the sub-shaft 234 to rotate, thereby driving the first reciprocating screw 223 to rotate, thus realizing the lateral movement of the monitoring camera assembly 24. This invention collects images and noise information through the indoor monitoring module 2 and the outdoor monitoring module 3, and transmits the images through the wireless transmission unit 5. The signal is transmitted to the centralized monitoring center for real-time monitoring. Meanwhile, the monitoring camera assembly 24 in the indoor monitoring module 2 and the waterproof camera 39 in the outdoor monitoring module 3 can continuously slide slowly horizontally under the action of a reciprocating screw. This greatly increases the monitoring range of a single camera, allowing a small number of cameras to cover the monitoring area inside the base station room 1 and at the outer entrance, avoiding blind spots. In addition to satisfying the horizontal movement and rotation of the camera, the sub-shaft 234, which provides power to the transmission chamber 23, is connected to the horizontal plate 22 via a spline connection, facilitating the disassembly and assembly of the transmission chamber 23. Similarly, the disc reduction motor 247 at the monitoring camera assembly 24 is also connected to the spherical camera 245 via a spline connection. This avoids complications during later motor maintenance and camera replacement due to the added transmission structure, making subsequent maintenance easier.

[0037] Example 2:

The monitoring camera assembly 24 includes a frustum 241 fixed to the bottom surface of the first T-shaped slider 222. The center of the bottom surface of the frustum 241 is fixed to the motor compartment 242. The bottom surface of the frustum 241 is located outside the motor compartment 242 and is fitted with a sleeve 243. The bottom surface of the sleeve 243 is rotatably connected to a circular plate 244. The bottom surface of the circular plate 244 is fixed to a spherical camera 245.

[0039] A disc geared motor 247 is fixedly connected inside the motor compartment 242. The shaft end of the disc geared motor 247 passes through the motor compartment 242 and is fixedly connected to a second splined shaft 248. A second splined groove 246 is opened on the top surface of the circular plate 244. The second splined shaft 248 is inserted into the second splined groove 246. The insertion of the second splined shaft 248 and the second splined groove 246 facilitates the disc geared motor 247 to drive the spherical camera head 245 to adjust its orientation. The splined insertion method also makes it easier to separate the spherical camera head 245 from the disc geared motor 247, which is convenient for subsequent maintenance.

[0040] A ring plate 2410 is fixedly connected to the outer side of the top surface of the sleeve 243. Multiple through holes 2411 are vertically opened on the ring plate 2410. Multiple threaded posts 249 are vertically fixed to the bottom surface of the frustum 241 at the same vertical position corresponding to the multiple through holes 2411. The multiple threaded posts 249 pass through the through holes 2411 and are threadedly connected to the locking nut 2412. The sleeve 243 is connected to the frustum 241 through the ring plate 2410. The sleeve 243 can be easily removed by removing the locking nut 2412.

[0041] Two side blocks 211 are fixed to both ends of the bottom surface of the mounting plate 21, and two mounting side plates 237 are fixed to both ends of the transmission chamber 23. A plug plate 212 is fixed to the side block 211 near the mounting side plate 237. A horizontal insertion port 238 is opened on the mounting side plate 237. The plug plate 212 passes through the insertion port 238 and is fixed to a horizontal threaded post 213. A hexagonal nut 214 is threaded on the horizontal threaded post 213. The transmission chamber 23 can be easily removed by removing the hexagonal nut 214, which facilitates the later maintenance of the dual-shaft geared motor 231.

[0042] Example 3:

[0043] Please see Figure 2 and 10 -11 is the third embodiment of the present invention. This embodiment is based on the first embodiment. A rotating door 11 is rotatably connected to one side of the base station equipment room 1. The outdoor monitoring module 3 includes two brackets 31 fixed to both ends of the top surface of the base station equipment room 1 near the rotating door 11. The ends of the two brackets 31 are fixed to rods 32. A second T-shaped groove 33 is opened on the bottom surface of the rod 32. A second T-shaped slider 34 is slidably connected in the second T-shaped groove 33. A vertical pole 37 is fixed to the bottom surface of the second T-shaped slider 34. A rotating rod 38 is rotatably connected to the bottom end of the vertical pole 37. A waterproof camera 39 is fixed to the free end of the rotating rod 38.

[0044] The second T-shaped slide groove 33 is rotatably connected to the second reciprocating screw 35, and the second T-shaped slider 34 is fixedly connected to the second threaded sleeve 36. The second reciprocating screw 35 is engaged with the second threaded sleeve 36. A small motor 314 is fixedly connected to one of the brackets 31. The shaft end of the small motor 314 is fixedly connected to the end of the second reciprocating screw 35. The sliding effect of the waterproof camera 39 is achieved through the meshing action of the second reciprocating screw 35 and the second threaded sleeve 36.

[0045] The bottom side wall of the upright 37 is fixed to the side compartment 310. The shaft end of the small geared motor 311 is fixed to the side compartment 310 and the worm gear 312 is fixed to it. The shaft end of the rotating rod 38 is located inside the side compartment 310 and is fixed to the worm wheel 313. The worm gear 312 meshes with the worm wheel 313, and the orientation position of the waterproof camera 39 is achieved through the worm gear 312.

[0046] Example 4:

[0047] This invention collects images and noise information through an indoor monitoring module 2 and an outdoor monitoring module 3, and transmits the image signals to a centralized monitoring center for real-time monitoring via a wireless transmission unit 5. Simultaneously, the monitoring camera assembly 24 in the indoor monitoring module 2 and the waterproof camera 39 in the outdoor monitoring module 3 can continuously and slowly slide horizontally under the action of a reciprocating screw, greatly increasing the monitoring range of a single camera. A small number of cameras can cover the monitoring area inside the base station room 1 and at the outer entrance, avoiding blind spots. In addition to satisfying the horizontal movement and rotation of the cameras, the sub-shaft 234, which provides power to the transmission chamber 23, is connected to the horizontal plate 22 via a spline connection, facilitating the disassembly and assembly of the transmission chamber 23. Similarly, the disc reduction motor 247 at the monitoring camera assembly 24 is also connected to the spherical camera 245 via a spline connection. This avoids complications during later motor maintenance and camera replacement due to the added transmission structure, making subsequent maintenance work easier.
