Description

Technical Field

[0001] This utility model relates to the field of fighting prevention and early warning technology, and in particular to a fighting prevention and early warning device based on audio and video fusion. Background Technology

[0002] Fighting refers to the act of two or more parties using force, such as fists, feet, or weapons, to achieve victory. Specifically, fighting refers to the act of two or more opposing parties, when their conflict reaches a breaking point, resorting to violence to subdue the other. The characteristics of fighting include a violent tendency and the intention to cause physical harm to others. This behavior usually stems from various conflicts. Regardless of the cause, fighting is an irrational and uncivilized act, and serious fights may even violate criminal law. Therefore, different approaches are needed depending on the circumstances, thus requiring the use of fight prevention and early warning devices to meet people's needs.

[0003] Currently, most anti-fighting and brawling prevention and early warning systems on the market rely on police patrols. However, cameras can only record fights and cannot provide prevention and early warning. Therefore, it is impossible to enable cameras to have prevention and early warning functions by integrating audio and video. Thus, there is a need for a fight prevention and early warning device to meet people's needs. Utility Model Content

[0042] Example 1: Refer to Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides a fight prevention and early warning device based on audio and video fusion. It can realize that most fight prevention and early warning on the market currently rely on police patrols to prevent and warn of fights. However, cameras can only record the people fighting and cannot provide prevention and early warning. Therefore, it is impossible for cameras to have prevention and early warning functions by fusing audio and video. Therefore, there is a need for a fight prevention and early warning device to meet people's needs. The device includes a mounting and fixing mechanism 1, which includes a mounting plate 101. A positioning plate 102 is mounted on one end of the mounting plate 101, and a support plate 103 is mounted on one end of the positioning plate 102.

A camera body 107 is mounted on the top end of the second hinge seat 106.

[0043] An infrared tracker 1072 is installed on the side wall of the camera body 107, and a microphone body 1071 is installed on the top of the camera body 107. The microphone body 1071 is designed to monitor the sound of people fighting.

Through the design of the voice and motion analysis device 1010, the device can monitor, prevent, and warn of fights among people.

[0046] The specific working principle is as follows: when it is necessary to prevent and warn of fights, the camera body 107 and the microphone body 1071 are designed so that the microphone body 1071 can perform sound recognition within the monitoring range of the camera body 107. At the same time, the microprocessor 104 uses the data monitored by the camera body 107 and the microphone body 1071 to intelligently identify the sound and human movements through the voice and action analysis device 1010. The microprocessor 104 has a built-in large model algorithm. When it detects that the sound and human movements are consistent with a fight, the microprocessor 104 analyzes the video and sound through the large model algorithm. When it analyzes the characteristics that match a fight, it triggers the alarm device 108 to quickly sound an alarm, thus providing real-time prevention and warning of fights. At the same time, the monitored images can also be displayed on the public security agency's display body 1011 and the operator's mobile phone through the signal transmission device 109, so that the fight can be dealt with in a timely manner.

[0047] Example 2: Refer to Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides a fight prevention and early warning device based on audio and video fusion. It can realize that most fight prevention and early warning on the market currently rely on police patrols to prevent and warn of fights. However, cameras can only record the people fighting and cannot provide prevention and early warning. Therefore, it is impossible to make the camera have the function of prevention and early warning by fusing audio and video. Therefore, there is a need for a fight prevention and early warning device to meet people's needs. The rotating adjustment mechanism 2 includes a mounting frame 201, which is installed at the bottom of the support plate 103. A first drive motor 202 is installed at the middle position of the bottom of the mounting frame 201. The top of the mounting frame 201 is rotatably mounted with a turntable body 204 that penetrates the support plate 103 through a bearing.

[0048] The output end of the first drive motor 202 is equipped with a first drive shaft 203 via a coupling, and the top end of the first drive shaft 203 is fixedly connected to the bottom end of the turntable body 204. By starting the first drive motor 202, the first drive shaft 203 and the turntable body 204 are driven to rotate simultaneously.

[0049] Angle adjustment mechanism 3 includes a fixed plate 301 and a sliding rod 307. The fixed plate 301 is mounted on the top of the outer wall of the turntable body 204. A fixed block 302 is mounted on the top of the fixed plate 301, and a second drive motor 303 is mounted on the top of the fixed block 302. The output end of the second drive motor 303 is mounted on the lead screw body 304 through a coupling.

[0050] The outer wall of the lead screw body 304 is threadedly connected to a threaded sleeve 305, and the outer wall of the threaded sleeve 305 is hinged to a hinge plate 306. The end of the hinge plate 306 away from the threaded sleeve 305 is hinged to the bottom end of the camera body 107. The threaded sleeve 305 can slide on the outer wall of the sliding rod 307 through the cooperation of the sliding sleeve 308 and the sliding rod 307.

The outer wall of the sliding sleeve 308 is fixedly connected to the outer wall of the threaded sleeve 305. The threaded sleeve 305 can slide on the outer wall of the sliding rod 307 through the sliding sleeve 308 in cooperation with the sliding rod 307.

[0053] The specific working principle is as follows: When fighting prevention and early warning are needed, the infrared tracker 1071 is designed so that when it detects a person, it can simultaneously activate the first drive motor 202 and the second drive motor 303 via the microprocessor 104. The first drive motor 202 drives the first drive shaft 203 and the turntable body 204 to rotate, thereby adjusting the monitoring angle of the camera body 107. At the same time, the second drive motor 303 drives the lead screw body 304 to rotate. The lead screw body 304 is threadedly connected to the threaded sleeve 305. Through the cooperation of the sliding rod 307 and the sliding sleeve 308, the rotation of the lead screw body 304 causes the threaded sleeve 305 to slide on the outer wall of the lead screw body 304 and pull the hinge plate 306 to rotate, thereby adjusting the up and down monitoring angle of the camera body 107. This allows the camera body 107 to follow people for real-time detection, thus improving the fighting prevention and early warning effect.
