Description

Technical Field

[0001] The present invention relates to the technical field of fighting monitoring and prevention, and in particular to a fighting prevention and early warning device based on audio and video fusion. Background Art

[0002] Fighting is a kind of illegal and disorderly behavior that is not tolerated by the society, which has a negative impact on social stability and people's lives. At present, the handling of fighting incidents is mainly based on post-event notification and calling the police. It is difficult for the public security organs to obtain the alarm information in the first time, and it is also difficult to collect evidence in the first time, which brings difficulties to the subsequent investigation and handling. For the analysis of fighting in the monitoring system, because only the information of the video is used, it is difficult to make an accurate judgment on the fight. For example, it is difficult to distinguish between fighting and more intense activities such as fast running, playing, exercising and doing exercises through video, which will produce more false alarms.

[0003] The existing patent (Announcement No.: CN102098492A) discloses a fight detection system and a detection method for audio and video joint analysis. The fight detection system for audio and video joint analysis includes a video acquisition module, an audio acquisition module, an algorithm detection module and a management module. The video acquisition module and the audio acquisition module use a camera, a capture card and a computer. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: when the device is used, the detection system directly detects the video and audio, and directly alarms when it meets the adjustment. However, the behavior of the crowd is difficult to detect, so when the system detects and directly alarms, it is easy to generate false alarms. Summary of the invention

[0004] In order to improve the above-mentioned device, when in use, the detection system is used to directly detect the video and audio, and an alarm is directly issued when the adjustment is met. However, the behavior of the crowd is difficult to detect. Therefore, when the system directly issues an alarm after detection, it is easy to cause a false alarm. The present invention provides a fight prevention and early warning device based on audio and video fusion.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-8 The present invention is described in further detail.

[0043] Please refer to the attached figure in the instruction manual Figure 1-8 An embodiment of the present invention is: a fighting prevention and early warning device based on audio and video fusion, including a detection mechanism 100, which includes a monitoring device body 101, the monitoring device body 101 includes a monitoring module 102, an algorithm detection module 103, an early warning module 104, an automatic control module 105, a manual control module 106 and an alarm module 107, the signal output end of the monitoring module 102 is electrically connected to the signal input end of the algorithm detection module 103, the algorithm in the algorithm detection module 103 is an existing technology, and the specific parameters can be adjusted according to the actual situation.

[0044] The monitoring module 102 monitors through the cameras installed in the area, and then transmits the collected signals to the algorithm detection module 103, judges the video and audio through the program set in the algorithm detection module 103, monitors the movements and language of the people in the monitoring range through the monitoring module 102, and transmits the monitoring data to the algorithm detection module 103 in real time, and compares the movements and language of the people through the program set in the algorithm detection module 103.

[0045] The signal output end of the algorithm detection module 103 is electrically connected to the signal input end of the early warning module 104, the signal output end of the algorithm detection module 103 is electrically connected to the signal input ends of the automatic control module 105 and the manual control module 106, the signal output ends of the automatic control module 105 and the manual control module 106 are electrically connected to the signal input end of the alarm module 107, the automatic control module 105 and the manual control module 106 are connected to the alarm module 107 in parallel, and the parallel connection enables the automatic control module 105 and the manual control module 106 to independently control the start-up of the alarm module 107, thereby reducing the problem of difficulty for police officers to respond in time when the operator is not in charge.

[0046] It should be noted that the carrier of the algorithm detection module 103 is a processor, and the processor is installed in the monitoring device body 101. The operator can directly watch the video and audio transmitted by the monitoring module 102 through the monitoring device body 101, and automatically judge through the algorithm detection module 103. When the judgment is successful, the algorithm detection module 103 starts timing when it transmits a signal to the early warning module 104. When the time reaches a certain time, for example two minutes, the algorithm detection module 103 transmits the signal to the automatic control module 105 again, thereby controlling the alarm module 107 to start through the automatic control module 105, and at the same time controlling the early warning module 104 to close through the algorithm detection module 103.

[0047] The adjustment mechanism 200 includes a portable housing 201, a telescopic rod 202 is fixedly provided on the inner wall of the portable housing 201, a buffer base 203 is fixedly provided on the extended end of the telescopic rod 202, the monitoring device body 101 is arranged on the buffer base 203, the buffer base 203 includes a fixed plate 203a and a movable shell 203b, the fixed plate 203a is fixedly provided on the extended end of the telescopic rod 202, the fixed plate 203a is movably provided in the movable shell 203b, and the fixed plate 203a and the movable shell 203b are both provided with a limiting groove 203c on the opposite side, and the fixed plate 203a and the movable shell 203b are provided with a limiting groove 203c. Two piston members 203d are symmetrically arranged between the movable shells 203b, and the upper ends and lower ends of the two piston members 203d are slidably matched with the inner wall of the limiting groove 203c. A baffle 203e is fixedly arranged at the bottom of the movable shell 203b for limiting the fixed plate 203a. When the monitoring device body 101 is impacted, the monitoring device body 101 drives the movable shell 203b to move downward. At this time, the movable shell 203b is buffered by the piston member 203d, thereby reducing the possibility of damage to the monitoring device body 101, and reducing the possibility of separation of the fixed plate 203a and the movable shell 203b through the baffle 203e.

[0048] The piston member 203d includes a groove plate 203d1 and a plug plate 203d2. The groove plate 203d1 and the plug plate 203d2 are fixedly provided with a limit block 203d3 at the opposite ends thereof. The limit block 203d3 is located in the limit groove 203c and slidably cooperates with the inner wall of the limit groove 203c. The plug plate 203d2 is movably plugged into the groove plate 203d1 and connected by setting a plurality of second springs 203d4. The groove plate 203d1 and the plug plate 203d2 are fixedly provided with a limit block 203d3 at the opposite ends thereof. The limit block 203d3 is located in the limit groove 203c and slidably cooperates with the inner wall of the limit groove 203c. The plug plate 203d2 is movably plugged into the groove plate 203d1 and connected by setting a plurality of second springs 203d4. A sealing strip is provided, which is slidably matched with the opposite sides of the groove plate 203d1 and the plug plate 203d2. When the movable shell 203b moves, it drives the plug plate 203d2 to move and insert into the groove plate 203d1. At this time, the second spring 203d4 is used to buffer the impact force on the movable shell 203b and the plug plate 203d2, and the sealing strip cooperates with the two piston members 203d to divide the space between the fixed plate 203a and the movable shell 203b into three independent spaces.

[0049] A scraping member 204 is provided on the buffer base 203, and the scraping member 204 is slidably matched with the outer wall of the monitoring device body 101. A tooth plate 205 is fixedly provided on the inner wall of the portable housing 201, and the tooth plate 205 is engaged with the scraping member 204. As the buffer base 203 moves downward, the tooth plate 205 is engaged with the scraping member 204, thereby prompting the scraping member 204 to operate to scrape the dust on the surface of the monitoring device body 101, thereby reducing the possibility of dust affecting the subsequent operator's use of the device.

[0050] It should be noted that a slide groove 201b is provided at the top of the inner wall of the portable housing 201, and two sealing plates 201c are symmetrically arranged in the slide groove 201b. A steel cable 201d is fixedly arranged on the bottom surface of the sealing plate 201c. The other end of the steel cable 201d passes through the portable housing 201 and is fixedly connected to the outer wall of the movable housing 203b. The bottom surface of the sealing plate 201c is connected to the inner wall of the portable housing 201 by setting a plurality of third springs 201e. Limiting strips 201f are fixedly arranged on the front and rear sides of the sealing plate 201c. The limiting strips 201f are located in the slide groove 201b and slide with the inner wall of the slide groove 201b. When the movable shell 203b moves up, it pulls the steel cable 201d to move synchronously. At this time, the steel cable 201d pulls the sealing plate 201c to move and prompts the portable shell 201 to open, and at the same time prompts the third spring 201e to compress and deform, so as to facilitate the monitoring device body 101 to move to the outside of the portable shell 201, and then facilitate the operator to use the monitoring device body 101. When the movable shell 203b moves down, the steel cable 201d loses its pulling force. At this time, the sealing plate 201c is pushed to reset and the portable shell 201 is sealed through the third spring 201e. At this time, the device completes its contraction, so that the operator can carry the device conveniently.

[0051] It should be noted that the outer wall of the portable housing 201 is provided with several cooling fans 201g, and the outer wall of the portable housing 201 is provided with a handle 201h. The handle 201h makes it easy for the operator to carry the device, thereby facilitating the transportation of the device, and the cooling fans 201g facilitate heat dissipation of the monitoring device main body 101.

[0052] It should be noted that the inner bottom wall of the portable housing 201 is fixedly provided with an outer spiral groove rod 201a, the bottom of the fixed plate 203a is movably plugged with a rotating cylinder 203f, the inner side of the rotating cylinder 203f is fixedly provided with a semicircular block 203g, the upper end of the rotating cylinder 203f passes through the fixed plate 203a and is fixedly sleeved with a cam 203h, the outer spiral groove rod 201a is movably plugged into the rotating cylinder 203f, and the semicircular block 203g is slidably matched with the inner wall of the outer spiral groove rod 201a, the two groove plates 203d1 are connected by setting a first spring 203d5, and a resisting rod 203d6 is fixedly provided on the side of the groove plate 203d1 facing the cam 203h. The resistance rod 203d6 slides with the outer wall of the cam 203h. When the telescopic rod 202 pulls the fixed plate 203a to move downward, the outer spiral groove rod 201a is inserted into the inside of the rotating cylinder 203f. At this time, the semicircular block 203g slides along the outer wall of the outer spiral groove rod 201a, thereby prompting the rotating cylinder 203f to drive the cam 203h to rotate, and pull the two groove plates 203d1 to shrink at the same time through the first spring 203d5, and prompt the resistance rod 203d6 to always contact with the outer wall of the cam 203h. As the cam 203h rotates, it continuously pushes the groove plate 203d1 and the plug plate 203d2 to move between the fixed plate 203a and the movable shell 203b.

[0053] It should be noted that nozzles 203i are fixedly connected to the left and right ends of the movable shell 203b, and the nozzle 203i is connected to the inner wall of the movable shell 203b. The air outlet end of the nozzle 203i faces the monitoring device body 101. When the groove plate 203d1 and the plug plate 203d2 move between the fixed plate 203a and the movable shell 203b, the airflow between the fixed plate 203a and the movable shell 203b is continuously pushed into the nozzle 203i, so that the dust on the surface of the monitoring device body 101 is blown away by the airflow sprayed by the nozzle 203i.

[0054] It should be noted that the scraper 204 includes two support plates 204a and a reciprocating screw rod 204b. The two support plates 204a are fixedly arranged on the top of the movable shell 203b. The reciprocating screw rod 204b is rotatably arranged between the two support plates 204a. Both ends of the reciprocating screw rod 204b pass through the two support plates 204a and are fixedly provided with gears 204c. The gears 204c are meshed with the toothed plate 205. The reciprocating screw rod 204b is threadedly sleeved with a scraper plate 204d. The scraping plate 204d is slidably matched with the outer wall of the monitoring device body 101, and bristles are provided on the side of the scraping plate 204d facing the monitoring device body 101. When the telescopic rod 202 pulls the fixed plate 203a and the movable shell 203b to move downward, the gear 204c and the reciprocating screw 204b are driven to rotate through the tooth plate 205. As the reciprocating screw 204b rotates, the scraping plate 204d and the bristles cooperate to scrape the dust on the surface of the monitoring device body 101.

[0055] Working principle: When using the fight prevention and early warning device based on audio and video fusion, the actions and language of the people within the monitoring range are first monitored by the monitoring module 102, and the monitoring data is transmitted to the algorithm detection module 103 in real time, and the actions and language of the people are compared through the program set in the algorithm detection module 103;

[0056] When a crowd is detected to have fighting-related behaviors, the control warning module 104 issues a warning, thereby prompting the operator to come to the monitoring device body 101 to make a secondary judgment on the video and audio, thereby increasing the accuracy of the judgment. When the operator determines that it is a fighting phenomenon, the manual control module 106 is activated to trigger the alarm module 107 to start the alarm, and the alarm of the warning module 104 is released at the same time, thereby notifying the police to go out and stop the fighting phenomenon in time;

[0057] When the alarm of the early warning module 104 is not turned off for a certain period of time, it means that there is no operator to make a judgment at this time. At this time, the algorithm detection module 103 directly controls the alarm module 107 through the automatic control module 105 to sound an alarm, thereby notifying the police to go out in time to stop the fighting, thereby reducing the problem that the police are difficult to go out in time when there is no operator;

[0058] When the device is not in use, the telescopic rod 202 pulls the buffer base 203 and the monitoring device body 101 into the portable housing 201, so that the monitoring device body 101 is protected by the portable housing 201, and as the buffer base 203 moves downward, the tooth plate 205 is engaged with the scraping member 204, so that the scraping member 204 is driven to operate to scrape the dust on the surface of the monitoring device body 101, thereby reducing the possibility that the dust affects the subsequent use of the device by the operator;

[0059] When the telescopic rod 202 pushes the monitoring device body 101 to the outside of the portable housing 201, it is convenient for the operator to use the monitoring device body 101, and when the monitoring device body 101 is hit, the buffering base 203 buffers the monitoring device body 101, thereby reducing the possibility of damage to the monitoring device body 101;

[0060] When the telescopic rod 202 pulls the fixed plate 203a and the movable shell 203b downward, the gear 204c and the reciprocating screw 204b are driven to rotate through the tooth plate 205. As the reciprocating screw 204b rotates, the scraping plate 204d cooperates with the bristles to scrape the dust on the surface of the monitoring device body 101.

[0061] When the telescopic rod 202 pulls the fixed plate 203a to move downward, the outer spiral groove rod 201a is inserted into the rotating drum 203f. At this time, the semicircular block 203g slides along the outer wall of the outer spiral groove rod 201a, thereby prompting the rotating drum 203f to drive the cam 203h to rotate, and pull the two groove plates 203d1 to shrink at the same time through the first spring 203d5, and prompt the abutment rod 203d6 to always abut against the outer wall of the cam 203h. As the cam 203h rotates, it continuously pushes the groove plate 203d1 and the plug plate 203d2 to move between the fixed plate 203a and the movable shell 203b, and continuously pushes the airflow between the fixed plate 203a and the movable shell 203b into the nozzle 203i, thereby spraying airflow through the nozzle 203i to blow away the dust on the surface of the monitoring equipment body 101.

[0062] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
