Description

Technical Field

[0001] The invention relates to the technical field of cleaning vehicles, and in particular to a variable frequency energy-saving fog cannon vehicle and an energy-saving method thereof. Background Art

[0002] Due to the continuous updating of new energy special vehicles, the driving range and working hours of new energy special vehicles have always been a major pain point for new energy vehicles. Therefore, as new energy vehicles continue to develop, the energy density of battery packs and cells has developed to a new height. For a special vehicle company, how to reduce the energy consumption of vehicles is a problem faced by every special vehicle company. Therefore, the energy consumption problem of urban special vehicles is not only new energy vehicles, but also the energy consumption problem of traditional fuel-powered special vehicles has received great attention. How to achieve energy conservation and emission reduction, reduce power loss, and increase vehicle mileage and working hours are issues that every special vehicle worker needs to consider.

[0003] For the regulation of urban air quality, dust suppression vehicles are mostly used to regulate air humidity and air quality. The work of dust suppression vehicles can be used to reduce dust and some suspended fine particles (PM2.5) in the air. After visiting and counting the dust suppression vehicles in various cities, it was found that at present, almost all dust suppression vehicles are running with the fog cannon at the highest displacement and highest wind speed when driving. Regardless of the air quality and humidity, they are running at full power. This is a huge loss of energy and greatly reduces the driving distance under the same energy. Summary of the invention

[0004] The problem solved by the present invention is: in order to solve the problems of large energy loss and long distance of fog cannon vehicles in the prior art, a variable frequency energy-saving fog cannon vehicle and an energy-saving method thereof are provided.

[0005] The present invention is implemented through the following technical scheme: a variable frequency energy-saving fog cannon vehicle, comprising:

[0006] Car body,

[0007] An air quality analyzer, which is installed on the vehicle and can detect at least PM2.5 and PM10 particles;

[0008] A fog cannon comprises a cannon barrel, a spray mechanism and an air blowing mechanism, wherein the power of the spray mechanism and the air blowing mechanism are both variable frequency adjustable;

[0009] A base, wherein the base is used to connect the fog cannon and the vehicle body, and the base can be adjusted in pitch and azimuth.

[0010] Furthermore, the fan motor of the spray mechanism and the water pump motor of the blower mechanism are both variable frequency motors.

[0011] Furthermore, it also includes a visual detection mechanism, which includes a camera and an image processing module. The camera faces backward, and the image processing module is electrically connected to the camera.

[0012] Another aspect of the present invention provides an energy-saving method for a variable frequency energy-saving fog cannon vehicle: an air quality analyzer carried on the vehicle is used to perform real-time detection of road air quality, and the detection data is transmitted to the controller of the fog cannon machine, and the controller of the fog cannon machine automatically adjusts the power of the spray mechanism and the blowing mechanism of the fog cannon according to the detection data.

[0013] Furthermore, the fog cannon includes the following working modes:

[0014] 1. Low power mode: when the air quality is good, that is, the content of particulate matter in the air is lower than the first set value, the low power mode is adopted, and the power of the spray mechanism and the blower mechanism is limited to the first set power;

[0015] 2. Normal mode: when the air quality is normal, that is, the content of particulate matter in the air is between the first set value and the second set value, the normal mode is adopted, and the power of the spray mechanism and the blower mechanism changes with the change of the content of particulate matter in the air;

[0016] 3. High power mode: when the air quality is poor, that is, the particulate matter content is higher than the second set value, the high power mode is adopted, and the power of the spray mechanism and the blower mechanism is limited to the second set power.

[0017] Furthermore, in the normal mode, the power of the spray mechanism and the blowing mechanism varies according to a particle-power curve, and the particle-power curve passes through two points: (first set value, first set power) and (second set value, second set power).

[0018] Furthermore, it also includes a visual detection mechanism, which includes a camera and an image processing module, the camera faces backward, and the image processing module is electrically connected to the camera. During the experimental stage, a large amount of image data taken under different PM2.5 concentrations is collected, and the image data covers different environments, lighting conditions and time periods to ensure the generalization ability of the model. These images are analyzed using image processing technology to extract image features related to PM2.5 concentrations, including image grayscale values, color distribution, texture information, etc. A computational model is trained based on the extracted image features and known PM2.5 concentration data using machine learning or deep learning algorithms. This model can calculate the PM2.5 concentrations corresponding to each area in the image based on the new image data, adjust the azimuth and pitch angles of the fog cannon, and align it with the area with the highest PM2.5 concentration in the image.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention can analyze the air quality of the driving section and set a standard value. When the air quality is below the standard value, the power of the fog cannon is reduced, which can reduce the power consumption of the vehicle and increase the single working time and distance of the vehicle.

[0021] 2. The present invention includes a visual detection mechanism that uses visual tracking to find the area with the highest particle concentration and perform fixed-point spraying to achieve the best dust suppression effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 2 This is the particle matter-power curve of the present invention.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-2 As shown, a variable frequency energy-saving fog cannon vehicle comprises:

[0027] The vehicle body 1 adopts a conventional truck head and chassis and is equipped with a water tank;

[0028] Air quality analyzer 2, the air quality analyzer 2 is installed on the vehicle, and can at least detect PM2.5 and PM10 particles, and can also be used for temperature and humidity detection. The air quality analyzer 2 of this scheme uses 485 type, and is connected to the controller of the fog cannon system through 485 signal.

[0029] The fog cannon 3 comprises a cannon barrel, a spray mechanism and an air blowing mechanism, wherein the power of the spray mechanism and the air blowing mechanism are both variable frequency adjustable;

[0030] The base 4 is used to connect the fog cannon 3 and the vehicle body 1, and the base 4 can be adjusted in pitch and azimuth.

[0031] In this solution, the air quality of the driving section can be analyzed and a standard value can be set. When the air quality is below the standard value, the power of the fog cannon is reduced. This can reduce the power consumption of the vehicle and increase the single working time and distance of the vehicle.

[0032] In practical applications, the fan motor of the spray mechanism and the water pump motor of the blower mechanism are both variable frequency motors, which control the spray volume and fan speed through the motor frequency, thereby achieving energy saving.

[0033] In practical applications, it also includes a visual detection mechanism 5, which includes a camera and an image processing module. The camera faces backward, and the image processing module and the camera are electrically connected. Through visual tracking, the area with the highest concentration of particulate matter can be found, and targeted spraying can be performed to achieve the best dust suppression effect.

[0034] Another aspect of the present invention provides an energy-saving method for a variable frequency energy-saving fog cannon vehicle: the air quality on the road is detected in real time using an air quality analyzer 2 carried on the vehicle, and the detection data is transmitted to the controller of the fog cannon machine 3, and the controller of the fog cannon machine 3 automatically adjusts the power of the spray mechanism and the blowing mechanism of the fog cannon according to the detection data. The fog cannon vehicle is equipped with an on-board air quality analyzer 2 to detect air humidity, temperature, PM2.5, PM10, and upload the detection data to the controller of the fog cannon. The power of the water pump and the fan of the fog cannon can be automatically adjusted through the fog cannon controller to reduce the energy consumption of the vehicle and increase the single working time and distance of the vehicle.

[0035] In practical applications, the fog cannon 3 includes the following working modes:

[0036] 1. Low power mode: when the air quality is good, that is, the content of particulate matter in the air is lower than the first set value, the low power mode is adopted, and the power of the spray mechanism and the blower mechanism is limited to the first set power;

[0037] 2. Normal mode: when the air quality is normal, that is, the content of particulate matter in the air is between the first set value and the second set value, the normal mode is adopted, and the power of the spray mechanism and the blower mechanism changes with the change of the content of particulate matter in the air;

[0038] 3. High power mode: when the air quality is poor, that is, the particulate matter content is higher than the second set value, the high power mode is adopted, and the power of the spray mechanism and the blower mechanism is limited to the second set power.

[0039] The working mode of the fog cannon can be automatically adjusted according to the temperature and humidity changes in different environments and different road sections; such working state can effectively reduce the energy consumption of the fog cannon and increase the working time.

[0040] In actual applications, in the normal mode, the power of the spray mechanism and the blowing mechanism changes according to the particle matter-power curve. The particle matter-power curve passes through two points: (first set value, first set power) and (second set value, second set power), ensuring that the power changes smoothly with the change of particle matter and meets the dust suppression requirements of different air qualities.

[0041] In practical applications, it also includes a visual detection mechanism 5, which includes a camera and an image processing module. The camera faces backwards, and the image processing module is electrically connected to the camera. In the experimental stage, a large amount of image data taken under different PM2.5 concentrations is collected. The image data covers different environments, lighting conditions and time periods to ensure the generalization ability of the model. The images are analyzed using image processing technology to extract image features related to PM2.5 concentrations, including the grayscale value, color distribution, texture information, etc. of the image. A computing model is trained based on the extracted image features and known PM2.5 concentration data using machine learning or deep learning algorithms. This model can calculate the PM2.5 concentration corresponding to each area in the image based on the new image data, adjust the azimuth and pitch angle of the fog cannon 3, and align it with the area with the highest PM2.5 concentration in the image. Through visual tracking, the area with the highest concentration of particulate matter is found, and fixed-point spraying is performed to achieve the best dust suppression effect.

[0042] To sum up, the variable frequency energy-saving fog cannon vehicle described in the present invention can analyze the air quality of the driving section and set a standard value. When the air quality is below the standard value, the power of the fog cannon is reduced. This can reduce the power consumption of the vehicle and increase the single working time and distance of the vehicle.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above implementation is only to illustrate the technical concept and features of the present invention, and its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention.
