Therefore, it is often necessary to use fog visibility detection devices to detect fog;

In foggy environments, the air is often mixed with dust, water vapor condensation, tiny particles and other pollutants.

[0021] S2, then the whole set of equipment is powered to monitor the fog in the highway environment;

[0022] S3. During monitoring, the operation of the first motor can be driven by remote control to rotate the first rotating rod, which in turn can drive the fan blades to rotate. The rotation of the fan blades can then allow air from the external environment to enter the detector through the air intake pipe. The optical sensor inside the detector detects fog in the air. When fog is detected in the air, a controller (not shown) controls a black light camera to take a picture of the sign board, processes and analyzes the captured graphic information, and determines the visibility of the fog by observing the clarity of the sign board at each position.

[0023] S4. During the visibility test, the position of the black light camera can be adjusted to take photos of signboards at different heights, so that the visibility of the fog can be judged by comparison, and corresponding early warning processing can be made.

[0024] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0025] 1. A fog detection component is provided. On the one hand, it can detect whether there is fog in the air in real time, so as to facilitate timely response and treatment. On the other hand, it can effectively remove impurities and particulate matter in the air during detection. These impurities and particulate matter may interfere with the normal operation of the detection equipment and affect the accuracy and reliability of the test results. Through filtering, interference factors are reduced, so that the test results can more truly reflect the characteristics of the fog. At the same time, the filtered air can protect the precision components of the detection equipment. Impurities and particulate matter may wear, clog or damage the sensitive components of the detection equipment, reducing the service life and performance of the equipment. Good air filtration can extend the service life of the detection equipment and reduce maintenance costs;

[0026] By providing a detector, an air inlet pipe, a filter cartridge, an L-shaped bracket, a first motor, a fan blade, a fixing block, a fixing ring, a brush plate and a filter plate, when detecting fog, impurities in the air can be filtered through the filter plate to ensure the accuracy of fog detection, and by providing a brush plate, impurities attached to the surface of the filter plate can be reciprocated to clean, thereby avoiding clogging of the filter plate and ensuring that air can smoothly enter the detector during detection;

[0027] And by arranging the T-shaped plate, the U-shaped frame, the third rotating rod, the second gear and the arc-shaped tooth plate, during use, the third rotating rod is controlled to reciprocate to drive the second gear to reciprocate, and the reciprocating rotation of the second gear can make the arc-shaped tooth plate reciprocate on the surface of the second gear through meshing, thereby driving the brush plate to clean the filter plate;

[0028] And through the use of the U-shaped block, the U-shaped frame, the second rotating rod, the belt connecting mechanism, the turntable, the first fixed shaft, the rotating rod, the moving rod, the fan-shaped toothed plate, the first teeth, the second teeth, the third rotating rod and the first gear, the power of the first motor can be transmitted to the second rotating rod, and then the third rotating rod is driven to rotate through the cooperation of the fan-shaped toothed plate, the first teeth, the second teeth and the first gear, thereby realizing the reciprocating rotation of the third rotating rod.

[0029] 2. A visibility monitoring component is provided to measure the visibility of fog, so as to facilitate corresponding emergency treatment according to different visibility;

[0030] By providing a second motor, a first screw, a limit guide rail, a screw sleeve, a black light camera and a protective cover, when the detector detects fog, a fog signal is sent to the controller, and the controller controls the black light camera to take a picture of the sign board, and then analyzes the photographed image to determine the visibility of the fog, so as to facilitate timely response and processing;

[0031] In addition, with the use of the resistance rod, the second limit switch and the first limit switch, the height position of the black light camera can be adjusted according to the fog visibility, so that the sign plates at different heights can be photographed, avoiding the sign plates in the front position blocking the sign plates in the back position, facilitating the analysis of the taken pictures and improving the accuracy of visibility detection.

[0032] 3. An intermittent lens cleaning component is provided to intermittently clean the dust on the surface of the blacklight camera lens to ensure the accuracy of the test data. Dust attached to the lens surface will scatter and block light, resulting in a reduction or distortion of the amount of light entering the test equipment, thereby affecting the accuracy of the test results. Regular cleaning can effectively avoid such errors and prevent dust accumulation from gradually changing the light transmission performance of the lens, ensuring that the conditions for each test are basically the same. Intermittent cleaning can keep the optical performance of the lens relatively stable, thereby ensuring the repeatability and reliability of the test results;

[0033] Through the coordinated use of an elastic airbag, an air delivery pipe, a curved hollow plate, a nozzle and an air intake pipe, the elastic airbag can be squeezed intermittently during the height adjustment of the blacklight camera, so that the gas in the elastic airbag can be sprayed toward the lens surface of the blacklight camera through the nozzle, and the airflow is used to blow away the dust attached to the lens surface, which is beneficial to improving the shooting quality.

[0071] During this process, the reciprocating rotation of the first gear 420 can drive the reciprocating rotation of the third rotating rod 421, and the reciprocating rotation of the third rotating rod 421 can drive the reciprocating rotation of the second gear 422, and the reciprocating rotation of the second gear 422 can make the arc-shaped tooth plate 427 move back and forth on the surface of the second gear 422 through meshing, thereby driving the brush plate 425 to clean the filter plate 426, which can effectively remove impurities and particulate matter in the air. These impurities and particulate matter may interfere with the normal operation of the detection equipment and affect the accuracy and reliability of the detection results. Through filtering, interference factors are reduced, so that the detection results can more truly reflect the characteristics of the fog. At the same time, the filtered air can protect the precision components of the detection equipment. Impurities and particulate matter may wear, block or damage the sensitive components of the detection equipment, reducing the service life and performance of the equipment. Good air filtration can extend the service life of the detection equipment and reduce maintenance costs;

[0072] When fog is detected in the air, the black light camera 513 is controlled by a controller (not shown) to take a picture of the sign board 510, and the photographed graphic information is processed and analyzed, and the visibility of the fog is judged by observing the clarity of the sign board 510 at each position;

[0073] During this process, when the signboard 510 located at 50 meters cannot be seen, it means that the visibility of the fog is less than 50 meters. At this time, a signal is sent to a controller (not shown), which controls the yellow flashing light 511 to flash, reminding the driver and passengers where the boundary of the highway is, and sends visibility information to the traffic management department to implement highway road closure. At the same time, the directional tweeter 512 is controlled to emit a sound to guide vehicles to leave the highway from the nearest exit as soon as possible, and reminds the vehicle to turn on the fog lights, low beam lights, clearance lights, front and rear position lights and hazard warning flashers, the speed shall not exceed 20 kilometers per hour, and keep a safe distance from the vehicle in front, and try to avoid sudden braking and sharp turns;

[0074] When the sign board 510 located at 50 meters can be seen, it means that the visibility of the fog is greater than 50 meters, and a visibility signal is sent to the controller. At this time, the controller controls the second motor 51 to run, and the operation of the second motor 51 can then drive the first screw 52 to rotate, and the rotation of the first screw 52 can then drive the blacklight camera 513 to rise through the cooperation of the screw sleeve 54. When the resistance rod 56 contacts the first limit switch 57, the first limit switch 57 sends a signal to the controller, and the controller controls the second motor 51 to stop running. At the same time, the controller controls the blacklight camera 513 to rise. The light-level camera 513 takes a picture. When the picture cannot see the signboard 510 at the position of 100 meters, it means that the visibility of the fog is between 50 meters and 100 meters. At this time, the visibility information of the fog can be sent to the controller, and the controller controls the yellow flashing light 511 to flash at a high frequency to remind passing vehicles, and controls the directional tweeter 512 to make a sound to remind vehicles to turn on fog lights, low beam lights, clearance lights, front and rear position lights, maintain a safe distance, and the speed should not exceed 40 kilometers per hour, and remind drivers to concentrate and pay close attention to the road conditions and traffic signal instructions ahead;

[0075] When the sign board 510 at a distance of 100 meters can be seen, it means that the visibility of the fog is greater than 100 meters, and a visibility signal is sent to the controller. At this time, the controller controls the second motor 51 to continue to run. The operation of the second motor 51 can then drive the first screw 52 to rotate. The rotation of the first screw 52 can then drive the black light camera 513 to rise through the cooperation of the screw sleeve 54. When the contact rod 56 contacts the second limit switch 58, the second limit switch 58 sends a signal to the controller, and the controller controls the second motor 51 to stop running. At the same time, the black light camera 513 is controlled by the controller. The camera 513 takes a picture. When the picture cannot see the signboard 510 at the position of 200 meters, it means that the visibility of the fog is between 100 meters and 200 meters. At this time, the visibility information of the fog can be sent to the controller, and the controller controls the yellow flashing light 511 to flash at a high frequency to remind passing vehicles. At the same time, the directional tweeter 512 is controlled to emit a sound to remind the vehicle to turn on the fog lights, low beam lights, clearance lights and front and rear position lights, keep a safe distance of more than 100 meters from the vehicle in front, control the speed within 60 kilometers per hour, and remind the driver to stay alert and be prepared for emergencies in advance;

[0076] When the signboard 510 at the 200-meter position can be seen, it means that the visibility of the fog is greater than 200 meters. At this time, only the controller directional tweeter 512 can generate sound to remind passing vehicles to pay attention to safety.

[0077] When the height position of the blacklight camera 513 is adjusted, the movement of the blacklight camera 513 can drive the fourth gear 610 to rotate on the surface of the rack 69. The rotation of the fourth gear 610 can drive the fourth rotating rod 62 to rotate. The rotation of the fourth rotating rod 62 can drive the cam 63 to rotate. The rotation of the cam 63 can intermittently squeeze the elastic airbag 65, so that the gas in the elastic airbag 65 is blown toward the lens of the blacklight camera 513 through the air pipe 66, so that the dust attached to the surface of the lens can be cleaned. Regular cleaning can effectively avoid such errors, and at the same time avoid dust accumulation that causes the light transmittance of the lens to gradually change, so as to ensure that the conditions of each detection are basically the same. Intermittent cleaning can keep the optical performance of the lens relatively stable, thereby ensuring the repeatability and reliability of the detection results.

[0078] The present invention also provides a highway fog visibility detection device and a method for using the device, comprising the following steps:

[0079] S1, transport the equipment to the location to be installed on the highway, then fix the installation base 1 on the side of the highway by bolts, then sequentially set identification plates 510 at the locations of 50 meters, 100 meters and 200 meters away from the detector 41, and fix the identification plates 510 on the side of the highway by the installation rod 59, and the installation heights of the three identification plates 510 are sequentially increased in the direction away from the detector 41;

[0080] S2, then the whole set of equipment is powered to monitor the fog in the highway environment;

[0081] S3. During monitoring, the first motor 45 is operated by remote control, and the operation of the first motor 45 can drive the first rotating rod 46 to rotate. The rotation of the first rotating rod 46 can then drive the fan blades 48 to rotate. The rotation of the fan blades 48 can then allow air in the external environment to enter the detector 41 through the air inlet pipe 42. The optical sensor inside the detector 41 detects fog in the air. When fog is detected in the air, the black light camera 513 is controlled by the controller (not shown) to take a picture of the identification plate 510, and the captured graphic information is processed and analyzed. The visibility of the fog is judged by observing the clarity of the identification plate 510 at each position.

[0082] S4. During the visibility test, the position of the black light camera 513 can be adjusted to photograph the signboards 510 at different heights, so that the visibility of the fog can be determined by comparison, and corresponding warning processing can be made.
