Description

Technical Field

[0001] The present invention relates to the field of intelligent security technology, in particular to a self-cleaning intelligent security monitoring device and a working method thereof. Background Art

[0002] Outdoor security monitoring equipment is easily contaminated by rain, snow, dust, and bird droppings, resulting in blurred monitoring images;

[0003] In related technologies, traditional manual wiping methods remove pollutants through physical contact, but have the disadvantages of low efficiency and high labor costs;

[0004] After improvements, a fixed spraying scheme was adopted to spray cleaning liquid at a fixed time through a preset program. Although it reduced manual intervention, the cleaning blind spots were large and resources were seriously wasted. The cleaning path and intensity could not be adjusted according to the actual pollution type (such as rain and snow adhesion or air pollutant adhesion), resulting in a high residual rate of stubborn stains, and the spraying operation was still performed during the pollution-free period, exacerbating the ineffective consumption of resources. Summary of the Invention

[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a self-cleaning intelligent security monitoring device and a working method thereof, which can perform self-cleaning based on the type of pollution, without the need for human intervention, and with a high degree of cleaning.

[0006] The technical solution adopted by the present invention is as follows: a self-cleaning intelligent security monitoring device, comprising:

[0007] Support seat;

[0008] A frame assembly is fixed on the support base, and is provided with a camera cavity and a scraping cavity inside the frame assembly. A pipeline fixing block with multiple pipeline jacks is provided above the camera cavity, and a guide rail is provided below the camera cavity.

[0009] A camera, mounted in the camera cavity;

[0010] The scraping assembly includes a turntable driven by a motor, a connecting rod with one end fixed to the turntable, and a slider hinged to the other end of the connecting rod through a connecting portion; the slider is provided with a guide groove that cooperates with the guide rail;

[0011] The air and water supply assembly cooperates with the pipe fixing block and includes water supply pipes symmetrically arranged on both sides of the pipe fixing block, the water inlet end of which is connected to the water supply unit, and the water outlet end is provided with a water nozzle inclined toward the camera lens;

[0012] Multiple air supply pipelines are arranged between the water supply pipelines on both sides, with the air inlet end connected to the air supply unit and the air outlet end arranged vertically downward;

[0013] The system further includes a control module for controlling the scraping assembly and the air and water supply assembly based on external meteorological data.

[0014] As a further improvement of the above technical solution:

[0015] In one embodiment, the turntable is connected to the motor output shaft via a coupling, and the slider is driven by the connecting rod to reciprocate along the length direction of the guide rail when the turntable rotates.

[0016] In one embodiment, there are multiple air supply pipelines, and the air outlets are arranged linearly just above the lens, forming a continuous air curtain barrier by simultaneously exhausting air.

[0017] In one embodiment, the control module includes:

[0018] Data acquisition unit, used to obtain environmental humidity, temperature and air pollutant concentration data;

[0019] an algorithm unit, configured to trigger an instruction based on whether the humidity exceeds a first threshold or whether the concentration of air pollutants exceeds a second threshold;

[0020] The execution unit is used to control the air supply unit to form an air curtain according to the instructions of the algorithm unit; or to trigger a cleaning instruction.

[0021] In one embodiment, the algorithm unit of the control module executes the following rules:

[0022] When the humidity is ≥60%, the air supply unit is triggered to output dry gas with a temperature higher than the ambient temperature to form an air curtain;

[0023] When PM2.5 concentration is ≥75 μg / m 3 , triggers a cleaning instruction every hour.

[0024] In one embodiment, the cleaning instructions are:

[0025] Water is supplied to the water supply pipes on both sides through the water supply unit and sprayed toward the lens position of the camera through the water nozzle. After the water spraying is completed, the turntable starts to rotate, driving the slider to reciprocate along the length direction of the guide rail. At this time, the flexible scraper scrapes off the water stains and contaminants on the lens.

[0026] In one embodiment, when the cleaning instruction ends, the contact end between the turntable and the connecting rod is located on the left side of the turntable, and the slider is located on the side close to the turntable, thereby preventing the slider from blocking the camera.

[0027] In one embodiment, the flexible scraper is made of rubber or silicone, and its length covers the horizontal width of the lens.

[0028] On the other hand, the present application also provides a method for operating a self-cleaning intelligent security monitoring device, comprising the following steps:

[0029] Real-time acquisition of environmental humidity, temperature and air pollutant concentrations through the data acquisition unit;

[0030] When the humidity is ≥60%, the air supply unit is controlled to deliver dry gas to the air supply pipeline to form an air curtain at the lens position;

[0031] When PM2.5 concentration is ≥75 μg / m 3 Execute cleaning instructions once an hour;

[0032] The cleaning instructions are:

[0033] a. Control the water supply unit to spray water toward the lens through the water nozzle;

[0034] b. Start the motor to drive the turntable to rotate, and the connecting rod drives the slider to reciprocate along the guide rail, so that the flexible scraper scrapes away the pollutants;

[0035] c. After cleaning is completed, the control slider is reset to its original position close to the turntable.

[0036] In one embodiment, the temperature of the drying gas forming the air curtain is 5-10° C. higher than the ambient temperature, and the air curtain continues until the humidity is lower than 60% and then stops.

[0037] The beneficial effects of the present invention are as follows:

[0038] The invention has a compact structure. The turntable drives the slider to reciprocate linearly along the guide rail via a connecting rod, ensuring that the flexible scraper always moves perpendicular to the lens surface. The scraping track covers the entire width of the lens, eliminating blind spots in cleaning. At the same time, the inclined water nozzles on both sides of the water supply pipeline form cross-flows, covering the curved surface of the lens. In conjunction with the flexible scraper, pollutants on the lens surface can be removed. The multiple air outlets of the air supply pipeline are vertically downward to form a continuous air curtain barrier, which is used for air curtain protection against rain and fog, avoiding lens fogging.

[0039] In addition, the present invention also has the following advantages:

[0040] The camera cavity and the scraping cavity of the present invention are independent of each other, thus avoiding the influence of mechanical vibration on imaging stability to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] See also Figure 1-Figure 4 , showing a structural diagram of a self-cleaning intelligent security monitoring device in this application.

[0057] The present application provides a self-cleaning intelligent security monitoring device, including a support base 100, a frame assembly 200 fixed on the support base 100, a camera 300 assembled in the frame assembly 200, a scraping assembly 400, an air and water supply assembly 500, and a control module 600.

[0058] In some embodiments, the support base 100 is a metal casting and is fixed to an outdoor wall or pole by bolts.

[0059] like Figure 2As shown, in some embodiments, the frame assembly 200 adopts a waterproof aluminum alloy shell, the interior of which is divided into an independent camera cavity 210 and a scraping cavity 220 by a partition. The scraping cavity 220 is located on one side of the camera cavity 210 and is used to accommodate the scraping assembly 400. The two cavities are independent of each other to minimize the transmission of mechanical vibration to the camera 300.

[0060] Furthermore, a pipeline fixing block 230 is provided on the top of the camera cavity 210 of the frame assembly 200. The fixing block includes a fixing block body 231 and a plurality of pipeline insertion holes 232, and a guide rail 240 is provided on the bottom.

[0061] In some embodiments, the camera 300 is installed at the center of the camera cavity 210, with the lens facing downward toward the open end of the camera cavity 210; further, a flexible shock-absorbing pad is configured at the bottom of the camera 300.

[0062] like Figure 3 As shown, in some embodiments, the scraping assembly 400 includes:

[0063] The turntable 410 is connected to the output shaft of the motor 470 through a coupling, and the motor 470 is fixed to the side wall of the scraping cavity 220;

[0064] A connecting rod 420, one end of which is eccentrically fixed to the surface of the turntable 410;

[0065] The slider 440 is hinged to the other end of the connecting rod 420 through the connecting portion 430. The bottom of the slider 440 is provided with a guide groove 460 that slides with the guide rail 240;

[0066] The flexible scraper 450 is made of silicone, has a length that matches the width of the lens, and is fixed vertically to the side of the slider 440 facing the lens;

[0067] When the motor 470 drives the turntable 410 to rotate, the connecting rod 420 drives the slider 440 to perform linear reciprocating motion along the guide rail 240, so that the flexible scraper 450 is in contact with the lens surface and scrapes it throughout the entire process.

[0068] Please continue reading Figure 2 In some embodiments, the air and water supply assembly 500 includes:

[0069] The water supply pipe 510 is symmetrically distributed on both sides of the pipe fixing block 230. The water inlet end is connected to the water supply unit 520 of the external water tank, and the water outlet end is equipped with an inclined water nozzle 530. The dual nozzles form a cross water flow to cover the lens surface;

[0070] The air supply pipeline 540 is located between the water supply pipelines 510 on both sides and includes multiple parallel gas pipelines. The air inlet end is connected to the air supply unit 550 with a heating module, and the air outlet end is arranged vertically downward to form a continuous air curtain.

[0071] See also Figure 4 In some embodiments, the control module 600 integrates a control circuit board including:

[0072] The data acquisition unit 610 is connected to the temperature and humidity sensor and the PM2.5 detector;

[0073] The algorithm unit 620 presets a threshold judgment rule, wherein the first threshold is humidity ≥ 60%, and the second threshold is PM2.5 ≥ 75 μg / m 3 ;

[0074] The execution unit 630 compares the data uploaded by the data acquisition unit 610 with the threshold value based on the algorithm unit 620, and controls the motor 470, the water supply unit 520 and the air supply unit 550 according to the instruction.

[0075] In actual work, the workflow of the present invention includes:

[0076] In anti-fog mode, when the data acquisition unit 610 detects that the ambient humidity is ≥ 60%, the algorithm unit 620 triggers the air supply unit 550 to output dry gas (the temperature of the dry gas is 5-10°C higher than the ambient temperature) to form an air curtain barrier through the air supply pipeline 540 until the humidity is less than 60%;

[0077] Cleaning mode, when PM2.5≥75μg / m 3 , execution unit 630 triggers every hour:

[0078] a. The water supply unit 520 sprays water through the water nozzle 530 to soften the pollutants, and stops after 10 seconds and proceeds to step b;

[0079] b. The motor 470 drives the turntable 410 to rotate, driving the slider 440 and the flexible scraper 450 to complete a single reciprocating scraping;

[0080] c. When the turntable 410 stops rotating, the fixed end of the connecting rod 420 is located at the limit position on the left side of the turntable 410, so that the slider 440 is reset to its initial position close to the turntable 410 to avoid blocking the lens field of view.

[0081] In summary, the camera cavity 210 and the scraping cavity 220 of the present invention are designed as independent cavities to ensure imaging stability; the air curtain anti-fog and the water spray mechanical scraping work together to solve the problems of rain and fog adhesion and air particulate matter residue; at the same time, the present invention collects environmental data based on the data acquisition unit 610, triggers self-cleaning on demand, and reduces resource consumption.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-described embodiments merely illustrate the implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
