Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to a video monitoring device and method for a smart community. Background Art

[0002] The monitoring system is composed of five major parts: video recording, transmission, control, display, and record registration. The camera transmits the video image to the control host through coaxial video cable, network cable, and optical fiber. The control host then distributes the video signal to each monitor and recording equipment. At the same time, the voice signal to be transmitted can be synchronously recorded into the recorder. Through the control host, the operator can issue instructions to control the up, down, left, and right movements of the pan / tilt head and to focus and zoom the lens. The control host can also be used to switch between multiple cameras and pan / tilt heads. Using a special recording processing mode, the image can be recorded, played back, processed, and the best recording effect can be achieved.

[0003] The existing video surveillance devices have the following inconveniences:

[0004] When the humidity is too high or there is some foggy weather, the surface of the monitoring equipment is prone to fogging or forming water droplets. These fog and water droplets will block the field of view of the monitoring equipment, making it impossible for the monitoring equipment to capture clear images, which seriously affects the normal operation of the monitoring equipment;

[0005] During the long-term operation of the monitoring equipment, the dust generated by vehicles in the community and some dust in the air are easily accumulated on the screen of the monitoring equipment, thus affecting the shooting of the monitoring equipment. At this time, the staff needs to climb to a high place to clean the monitoring equipment, but this cleaning method is very troublesome and also has certain risks;

[0006] In hot weather, monitoring equipment easily generates heat during operation. At the same time, the heat dissipation efficiency of monitoring equipment is poor. Once the internal temperature is too high, it is easy to affect the internal components of the monitoring equipment, thereby shortening the service life of the monitoring equipment. Summary of the invention

[0016] Preferably, a through slot is provided at one end of the mounting plate, and the cover plate is located inside the through slot.

[0017] A method for using a video surveillance device for a smart community, the steps of use are as follows:

[0018] Step 1: When there is some water mist on the surface of the protective cover, which affects the shooting of the device, first start the drive motor, and then the drive motor drives the shaft A and gear A to rotate, and the gear A drives the protective cover to rotate through the gear ring A, and then the protective cover and the scraper are rubbed to scrape off the water mist on the surface of the protective cover;

[0019] Step 2: When the surface of the protective cover needs to be cleaned, first open the solenoid valve, and then the cleaning liquid in the purification liquid tank falls to the bottom of the liquid passage pipe. At this time, start the injection pipe to drive the rotating shaft A, gear A and gear ring A to rotate, so that the gear ring A drives the fan plate and the rotating shaft B to rotate, and then the incomplete gear rotates, and then the incomplete gear drives the gear ring B and the slide bar to move up and down reciprocatingly, so that the purification liquid flowing into the liquid passage pipe drips into the surface of the protective cover through the gap of the injection pipe, and the surface of the protective cover is cleaned by the action of the protective cover and the scraper;

[0020] Step three: When the temperature of the surveillance camera gradually rises during operation, the temperature inside the surveillance camera is transferred to the surface of the surveillance camera, and then after the airbag absorbs the heat of the surveillance camera, the gas inside it gradually expands due to the heat, which opens the airbag, pushes the sliding plate upward, and squeezes the start button, thereby starting the servo motor, and then the servo motor drives the cover to rotate. After the cover rotates to a certain position, it no longer moves due to the restriction of the limit groove and the limit block, and then the other set of cover plates at the bottom continues to rotate with the servo motor until multiple sets of cover plates overlap and the servo motor stops running, thereby opening the through slot, increasing the ventilation of the equipment, and allowing the equipment to dissipate heat quickly.

[0021] Compared with the prior art, the present invention provides a video surveillance device for a smart community, which has the following beneficial effects:

[0022] 1. The present invention cooperates with the driving motor, the rotating shaft A, the gear A, the mounting bin B, the gear ring A, the arc plate and the scraper. When water droplets or mist are formed on the surface of the monitoring equipment, the staff can control the protective cover to rotate so that the protective cover rubs against the scraper, and then the water droplets or mist on the surface are scraped off, effectively preventing the situation that the normal use of the monitoring equipment is affected, and the cleaning operation is easy.

[0023] 2. The present invention, through the cooperation of the rotating shaft B, the gear ring B, the sealing plate, the sliding rod, the incomplete gear and the fan-shaped plate, starts the solenoid valve and controls the protective cover to rotate when there are stains on the surface of the protective cover that affect the normal use of the monitoring equipment. Then, the force generated by the rotation of the protective cover can be used to intermittently drip cleaning liquid onto the surface of the protective cover, thereby saving the amount of cleaning liquid. At the same time, the surface of the protective cover is cleaned by the scraper to ensure the cleanliness of the surface of the protective cover. At the same time, the cleaning liquid inside the purification liquid tank can also absorb the heat of the monitoring camera, thereby improving a certain heat dissipation effect.

[0024] 3. The present invention, through the cooperation of the fan-shaped plate, servo motor, cover plate, limit groove, rotating rod, airbag, sliding plate and start button, when the temperature inside the surveillance camera reaches a certain value, multiple sets of cover plates will be folded to open the through groove, increase the ventilation volume, speed up the heat dissipation speed of the equipment, thereby preventing the internal components of the equipment from being damaged due to the high temperature generated during operation, and ensuring the normal operating environment of the equipment.
