Description

Technical Field

[0001] The present invention relates to the field of video alarm devices, and particularly to a video alarm all-in-one machine. Background Art

[0002] A video alarm machine is a brand-new security prevention device, often installed in important monitoring places such as indoors, factories, warehouses, etc. It is equipped with a camera and a wireless signal transmission module inside. The camera continuously checks for suspicious personnel in real time. At the same time, the camera is capable of intelligently judging whether a fire occurs in the monitoring area through image analysis means. When an illegal intruder appears or a fire is detected in the monitoring area, the video alarm machine will promptly transmit the picture in the form of video transmission to the alarm center through the wireless signal transmission module. For example, a video linkage-based fire remote alarm monitoring and processing system disclosed in Patent CN113990020A can actively send a signal to the remote monitoring end when an abnormality is found during use. After receiving the signal, the remote monitoring end can detect the surrounding environment by adjusting the angle of the monitoring camera, with simple operation and wide application.

[0003] However, the video linkage-based fire remote alarm monitoring and processing system described in this patent has the following problems during operation:

[0004] Since the video alarm machine is usually installed in a high-altitude area, when a fire occurs, smoke will quickly fill the high-altitude area. A large amount of soot will cover the transparent cover protecting the camera, seriously affecting the monitoring vision of the camera, resulting in limited content of the video information transmitted by the video alarm machine. In addition, if the fire is too large, the environment temperature where the video alarm machine is located is relatively high. The camera and the signal transmission module are prone to component failures and cannot work properly in a high-temperature environment for a long time, affecting the durability of the video alarm machine to continuously transmit video signals for a long time. Summary of the Invention

[0040] The illegal intrusion alarm work of this video alarm all-in-one machine:

[0041] The video alarm integrated machine is installed in an area with a wide view at a high altitude through the fixed installation shell 1, and the air inlet pipe 52 and the exhaust pipe 92 penetrate through the building wall, so that the outer ends of the air inlet pipe 52 and the exhaust pipe 92 are communicated with the external air outside the building. The external circuit system supplies power to the camera 45 and the infrared induction module 48 synchronously. An infrared induction module 48 is installed below the camera 45. After the infrared induction module 48 recognizes the infrared rays emitted by the body of the person entering the monitoring area, the image recognition system built in the camera 45 checks the person. During this period, the output shaft of the first motor 53 slowly drives the first rotating shaft 54 to rotate, the first rotating shaft 54 drives the first straight gear 56 to rotate, the first straight gear 56 meshes with the second straight gear 63 and drives it to rotate, the second straight gear 63 meshes with the tooth ring 42 to drive the turntable 41 to rotate inside the fixed cover 3, and the turntable 41 drives the connected camera 45, reserve battery 46, signal transmission module 47 and transparent cover 44 to rotate. By continuously changing the monitoring area of the camera 45, the monitoring range of the camera 45 is expanded.

[0042] When the image recognition system built in the camera 45 cooperates with the infrared induction module 48 to recognize the intrusion of illegal personnel, the camera 45 actively transmits the video images to the alarm center continuously through the signal transmission module 47, and tracks and monitors the illegal intruders in real time, helping the police or security personnel to understand the on-site situation, which is conducive to the police or security personnel to quickly capture the illegal intruders.

[0043] The fire alarm work of this video alarm integrated machine:

[0044] During the continuous monitoring and checking of illegal intruders by the camera 45 of this video alarm integrated machine, at the same time, the gas detection module 32 on the outer surface of the fixed cover 3 monitors the temperature and humidity of the air in real time. When the image recognition system built in the camera 45 recognizes a fire phenomenon in the monitoring field of view, and the gas detection module 32 detects that the temperature and humidity of the air are abnormal, the camera 45 actively transmits the video images to the alarm center continuously through the signal transmission module 47, and tracks and monitors the fire situation at the monitoring site in real time, helping the police or security personnel to understand the on-site situation, which is conducive to the police or security personnel to quickly make corresponding solutions to the fire situation.

[0045] When the fire situation is severe and affects the normal power supply of the camera 45 by the external circuit, the reserve battery 46 supplies emergency power to the camera 45 to ensure that the camera 45 can continuously feedback the on-site images to the alarm center in the form of video signals.

[0046] During the continuous monitoring of the fire situation at the scene by the camera 45, the telescopic end of the electric push rod 61 drives the slider 62 to move upward along the air duct 51. The slider 62 drives the second spur gear 63 to move upward away from the first spur gear 56 and the toothed ring 42, so that the monitoring view of the camera 45 stays at the fire scene. Subsequently, the delivery pump in the spray water tank 2 transports the spray water inside the spray water tank 2 to the atomizer 71 through the liquid suction pipe 72. The atomizer 71 sprays the spray water in the form of spray water mist into the tee pipe 73. At the same time, the output shaft of the first motor 53 quickly drives the first rotating shaft 54 to rotate. The first rotating shaft 54 drives the first fan 55 to rotate. The rapidly rotating first fan 55 sucks the outside cold air into the air duct 51 through the air inlet pipe 52. The cold air flow in the air duct 51 enters the annular liquid pipe 74 through the tee pipe 73. During this process, the cold air flow drives the spray water mist in the tee pipe 73 into the annular liquid pipe 74. The cold air flow drives the spray water mist to be sprayed downward from the nozzle 75 onto the outer surface of the transparent cover 44, realizing that the spray water mist is continuously sprayed on the transparent cover 44 to wash away the soot adhering to its surface. At the same time, the cold air drawn in from the outside is sprayed onto the outer surface of the transparent cover 44 to cool it, preventing the temperature of the spray water mist from rising rapidly in a high-temperature environment and ensuring that the temperature of the outer surface of the transparent cover 44 is controlled.

[0047] At the same time that the cold air flow drives the spray water mist to be sprayed downward from the nozzle 75 onto the outer surface of the transparent cover 44, the spray water mist sprayed from the nozzle 75 above the shooting direction of the camera 45 is collected in the liquid collecting groove 82 of the collecting plate 81. The spray water mist continuously accumulates in the liquid collecting groove 82 and converges into complete spray water. The spray water flows downward along the drainage sieve wool 84 through the liquid guide pipe 83, so that the spray water flows along the drainage sieve wool 84 to the area of the outer surface of the transparent cover 44 within the monitoring range of the camera 45, preventing the imaging clarity of this area of the transparent cover 44 from being affected by the spray water droplets formed by the adhesion of a large amount of spray water mist. At the same time, during the downward flow of the spray water along this area of the transparent cover 44, it can effectively wash away the soot adhering to the outer surface of this area of the transparent cover 44 downward.

[0048] The spray water dripping downward from the outer surface of the transparent cover 44 is collected by the return hopper 21. After the spray water filters out impurities through the filter screen 22, it flows back to the spray water tank 2, enabling most of the spray water in the spray water tank 2 to be recycled and increasing the duration of the continuous cleaning and cooling work of the transparent cover 44.

[0049] During the continuous cleaning and cooling of the transparent cover 44 by the sprayed water, the output shaft of the second motor 93 drives the second fan 94 to rotate at a high speed. The second fan 94 rotating at a high speed timely sucks the flue gas around the video alarm integrated machine into the annular air pipe 91 through the ventilation groove 31 and the air collecting groove 911, and discharges the flue gas in the annular air pipe 91 outwards through the exhaust pipe 92, reducing the accumulation of flue gas around the camera 45, and ensuring that the camera 45 and the signal transmission module 47 in the transparent cover 44 can continuously and stably transmit the video picture to the alarm center in real time for a long time.
