Description

Technical Field

[0001] The utility model relates to the technical field of campus monitoring, and in particular to a campus monitoring and management system based on the Internet of Things. Background Art

[0002] Campus safety is a crucial aspect of educational institutions, and campus surveillance and management systems are a key technology for maintaining campus safety. With technological advancements, campus surveillance and management systems have evolved from traditional analog monitoring to today's digital, networked, and intelligent monitoring. However, traditional surveillance cameras often face significant challenges at night or in low-light conditions, significantly reducing their effectiveness and making it difficult to capture critical monitoring information. This poses a potential risk to campus safety.

[0003] Currently, most surveillance cameras on the market are equipped with night vision capabilities, but the switching methods for night vision filters are insufficient. Some cameras use automatic switching of night vision filters, which improves surveillance effectiveness to a certain extent. However, this automatic switching relies on complex electronic systems and algorithms, which is not only costly, but also often inaccurate and in-time due to the complex changes in ambient light. In practice, this automatic switching is often not accurate or timely, resulting in blurred, overexposed, or dark images.

[0004] On the other hand, some cameras use fixed night vision filters. This means the camera is factory-installed with a fixed night vision filter that cannot be switched based on ambient light conditions. While this approach reduces costs, it sacrifices flexibility and adaptability in the surveillance image. This is especially true when there is a significant difference in light between day and night, where fixed night vision filters often fail to meet monitoring needs. Therefore, it is necessary to propose an IoT-based campus surveillance management system to address these issues. Utility Model Content

In the accompanying drawings, for clarity, the thickness of layers and regions is exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0022] See also Figures 1 to 4 The embodiment of the utility model provides a campus monitoring and management system based on the Internet of Things, including: a monitoring device 1, a camera mounting frame 2, a filter storage box 3, a filter fixing frame 4 and a filter 5.

[0023] Specifically, a lens 11, a magnetic positioning hole 12, and a filter identification sensor 13 are provided at the front end of the monitoring device 1. The magnetic positioning holes 12 are located at the four corners of the front end of the monitoring device 1. The four magnetic positioning holes 12 are distributed in a rectangular shape. Magnets are provided in the magnetic positioning holes 12, which can adsorb the metal fixing columns 44 to fix the filter 5.

[0024] The monitoring device 1 is internally equipped with a microcontroller 14 and a wireless communication module 15. A filter recognition sensor 13 is connected to the microcontroller 14, which in turn is connected to the wireless communication module 15. The filter recognition sensor 13 can be a light sensor. The filter recognition sensor 13 transmits signals to the microcontroller 14, which in turn communicates with the campus monitoring and management system server via the wireless communication module 15.

[0025] A camera mounting bracket 2 is provided at the rear bottom of the monitoring device 1. The bracket 2 comprises a base plate 21, fastening screws 22, a support plate 23, a connecting plate 24, and a wall mounting plate 25. The base plate 21 is mounted to the rear bottom of the monitoring device 1 using the fastening screws 22. The support plate 23 is connected to the lower rear end of the base plate 21. One end of the connecting plate 24 is pivotally connected to the support plate 23, and the other end of the wall mounting plate 25 is fixedly connected to the connecting plate 24. Through-holes 26 are provided in the wall mounting plate 25. The angle between the monitoring device 1 and the base plate 21, as well as the angle between the support plate 23 and the connecting plate 24, can be adjusted to adjust the position of the monitoring device 1 to meet actual monitoring needs. The wall mounting plate 25 can be secured to the wall by inserting fixing nails through the through-holes 26 of the wall mounting plate 25 to achieve installation of the monitoring device 1.

[0026] A filter storage box 3 is provided at the bottom front end of the monitoring device 1. This box comprises a body 31 and a lid 33. The body 31 is provided with several layers of filter cavities 32 from top to bottom. The lid 33 is hinged to the bottom front end of the body 31. The dimensions of the filter cavities 32 match those of the filters 5, allowing different filters, such as ultraviolet filters, neutral density filters, and infrared filters, to be placed in different filter cavities 32.

[0027] The filter fixing frame 4 includes a limiting cylinder 41, a sliding rod 42, a fixing column mounting rod 43 and a metal fixing column 44. The limiting cylinder 41 is arranged at the upper and lower positions on both sides of the monitoring device 1. One end of the sliding rod 42 is slidably connected to the inside of the limiting cylinder 41 and a positioning pin is provided at the end to prevent the sliding rod 42 from falling off from the limiting cylinder 41. The other end of the sliding rod 42 is vertically connected to the fixing column mounting rod 43, and the metal fixing column 44 is provided on the inner side of the fixing column mounting rod 43; the four corners of the filter 5 are provided with fixing holes 55, and the metal fixing column 44 passes through the fixing hole 55 and is attracted into the magnetic positioning hole 12 to fix the filter 5 in front of the lens 11.

[0028] The filter 5 comprises a filter frame 51, a filter body 52, and a handle 53. The filter body 52 is positioned in the center of the filter frame 51, opposite the lens 11. A filter identification hole 54 and a fixing hole 55 are provided on the filter frame 51. The handle 53 is positioned in the center of the bottom of the filter frame 51 to facilitate removal of the filter 5 from the filter storage box 3. A recessed portion 16 is provided at the lower front end of the monitoring device 1 to accommodate the handle 53. When the filter 5 is installed in front of the lens 11, the handle 53 enters the recessed portion 16, preventing interference between the handle 53 and the monitoring device 1. A strip-shaped hollow groove 34 is provided in the center of the cover 33. The position of the strip-shaped hollow groove 34 corresponds to that of the handle 53, preventing interference between the handle 53 and the cover 33 after the filter 5 is placed in the filter accommodating cavity 32.

[0029] The filter 5 is provided with several filter identification holes 54 in an area outside the corresponding lens 11. Each of these holes 54 is provided with a shield. The shields corresponding to different filter identification holes 54 are located in different positions. The number and position of the filter identification sensors 13 correspond to the various filter identification holes 54. When different filters 5 are installed, the shields of the filter identification holes 54 are located in different positions, allowing them to be sensed by different filter identification sensors 13. This facilitates remotely determining the type of filter 5 currently installed from the campus monitoring and management system server.

[0030] The present invention provides an Internet of Things-based campus monitoring and management system. The method for using it is as follows: When the filter 5 needs to be replaced, the cover 33 is opened and the filter 5 to be replaced is pulled out via the handle 53. The sliding rod 42 is pulled out to remove the existing filter 5, and the filter 5 to be replaced is replaced. The filter fixing frame 4 is then pushed to the front of the monitoring device 1. The metal fixing post 44 passes through the fixing hole 55 and engages with the magnetic positioning hole 12, securing the filter 5 in front of the lens 11. Different filters can be flexibly replaced according to the usage requirements of the monitoring device. The filter can be switched between daytime and nighttime to adapt to different lighting conditions. The structure is simple and reliable.
