Description

Technical Field

[0001] The present invention belongs to the technical field of domestic waste cleaning, and in particular relates to a method and system for classifying, cleaning and transporting domestic waste. Background Art

[0002] With the progress of urbanization and the improvement of people's living standards, more and more garbage is generated in cities. The unreasonable layout of urban garbage bins and the low degree of automation of the removal method have brought a lot of inconvenience to life. In the era of "smart city", Internet of Things technology and information and communication technology have become an indispensable part of modern urban domestic waste management planning and design. At the same time, due to the rapid increase in the amount of garbage and the complexity of garbage types, it is urgent to implement garbage classification to promote resource recycling and achieve sustainable development. There are also methods in the prior art for garbage collection classification and dispatching the walking routes of garbage collection vehicles based on the Internet of Things.

[0003] For example, a Chinese patent with application number 202111616323.X in the prior art discloses a classified garbage intelligent transportation management system and method, in which weighing sensors are set at the bottom of the classified garbage bins at all garbage bin placement points within the jurisdiction of the garbage recycling station, and the weight data of all garbage bins are collected into the garbage bin database; then, according to the preset route, the weights of the garbage bins in sequence along the preset route are accumulated to obtain the maximum actual load of the classified garbage transport vehicle, that is, the transportation route is calculated. Garbage collection and transportation according to the transportation route makes classified garbage transportation management smarter and more efficient. However, the technology disclosed in this patent does not accurately classify garbage of different dryness and wetness.

[0004] For example, a Chinese patent with application number 202111015308.X in the prior art discloses a garbage collection and dispatching method and device, which obtains the garbage distribution map by obtaining the status information of the garbage can, calculates the garbage collection routes of each sanitation vehicle according to the number and location information of the sanitation vehicles and the information of the full garbage bucket points, and sends the garbage collection routes to the corresponding sanitation vehicles, so that the sanitation vehicles can clean up the garbage at the garbage station according to the garbage collection routes. Compared with the traditional manual timed and fixed-point garbage processing, this method can obtain the garbage can information of the garbage point in real time, automatically generate a full garbage bucket cleaning route, and can process the full garbage bucket in time. For garbage points without full buckets, they are not put into the garbage cleaning route, saving cleaning time and cleaning costs.

[0005] However, the domestic waste collection and transportation method disclosed in the above prior art does not make an optimized choice for the direction of travel within each garbage collection point, nor does it determine the route plan for whether the garbage collection vehicle turns at each garbage collection point to reach the next garbage collection point or directly connects in a straight line to reach the next garbage collection point. In addition, different garbage collection vehicles have different models and lengths, which leads to congestion at the garbage collection point when turning from one garbage collection point to another, or the scattering of the collected garbage when a collision occurs due to incomplete turns, which can easily cause the duration of the entire walking route to exceed the specified time, causing delays. Summary of the invention

[0070] The beneficial effects of the present invention are:

[0071] 1. The method for classifying, cleaning and transporting domestic waste provided by the present invention firstly weighs and roughly classifies the monitored domestic waste, and uses ultrasonic signal parameters and attenuation coefficient, refractive coefficient, mixed polarization coefficient, dryness composite specific gravity coefficient, and wetness composite specific gravity coefficient to subdivide the dryness and humidity calculation model and dynamically set the humidity threshold value. After classifying domestic waste with different dryness and humidity, the angle and geographic coordinates of domestic waste cleaning and transport vehicles at different intermediate waste collection points in a plane rectangular coordinate system are monitored in real time. The minimum turning radius is limited by the front and rear wheelbases of the domestic waste cleaning and transport vehicles, and then the total plane Euler distance D between the starting point and the target end point is determined. toatalThe relationship between the turning angle at each intermediate garbage collection point, the turning arc walking path, the straight-line distance between the common tangent segments of the turning circles of the two intermediate garbage collection points, and the turning angle and turning walking path to reach the next intermediate garbage collection point are used to construct a calculation model for minimizing the total length of the turning walking path of the circular turning method, and then the optimal angle between the plane rectangular coordinate system and the geodetic coordinate system of each intermediate garbage collection point is determined, and this is used as the judgment standard. , determine the left or right turn direction of each intermediate garbage collection point to make all the overall circular arc turning walking paths of each intermediate garbage collection point the shortest; then determine the predicted value of the angle of each intermediate garbage collection point with the x-axis of the geodetic coordinate system in the plane rectangular coordinate system as its angle update value, use genetic algorithm to iteratively optimize, and judge whether it is the optimal angle through the constructed fitness value, and then substitute it into the constructed circular arc turning mode turning walking path total length calculation model, further optimize the angle of each intermediate garbage collection point with the x-axis of the geodetic coordinate system in the plane rectangular coordinate system when turning, so as to improve the accuracy of the calculation result.

[0072] The method provided by the present invention can accurately classify the dryness and wetness of domestic garbage, thereby avoiding the low efficiency of domestic garbage treatment caused by the rough classification in the early stage and the mixing of dry and wet garbage, which leads to the later domestic garbage treatment method specifically for dry garbage or wet garbage. In addition, according to the front and rear wheelbases of different domestic garbage cleaning and transportation vehicles, it is determined that it is more appropriate to adopt an arc turning or a straight turning point at each intermediate garbage collection point, thereby avoiding the situation that the domestic garbage cleaning and transportation vehicle is inconvenient to turn and causes road congestion, or the turning causes collision with surrounding buildings or vehicles, and the garbage scattered in the garbage truck causes environmental pollution and unnecessary cleaning. Finally, a genetic algorithm is used to iteratively optimize the angle of the x-axis of the earth coordinate system in the plane rectangular coordinate system when the circular arc turning method of each intermediate garbage collection point is used, thereby optimizing the control of the walking direction of the domestic garbage cleaning and transportation vehicle, avoiding the deviation of the overall walking path caused by inaccurate control and causing the path to be too long, and improving the precision and accuracy of control.

[0073] 2. The method for classifying, cleaning and transporting domestic waste provided by the present invention integrates the attenuation coefficient η and the reflection coefficient κ of the ultrasonic signal caused by domestic waste, and finally constructs a calculation model for the dryness and humidity DH(t) of the subdivided domestic waste, and determines whether it is greater than the humidity threshold DH thresTo subdivide the dryness and wetness of the monitored domestic waste, and calculate the dryness composite gravity coefficient λ1 and the moisture composite gravity coefficient λ2 of the domestic waste after rough classification and weighing, so as to effectively and accurately judge the dryness and wetness of the domestic waste, avoiding the unclear distinction of domestic waste caused by rough classification, which leads to inaccurate classification in the later stage.

[0074] 3. In the method for classifying, cleaning and transporting domestic waste provided by the present invention, the judgment basis for the garbage subdivision in step S1 is: the humidity threshold value, which changes dynamically with various influencing factors and the total monitoring time, thereby more effectively determining the humidity threshold value of different environmental factors and the monitored waste conditions, and effectively dividing the monitored waste into a measurement scale for the mixed dry and wet waste, thereby avoiding misjudgment when performing dry and wet waste subdivision when the temperature threshold is only at one point value.

[0075] 4. In the method for sorting, cleaning and transporting domestic waste provided by the present invention, in step S2, the straight-line plane Euler distance between each intermediate waste collection point and the first intermediate waste collection point (starting point) and the last intermediate waste collection point (target end point) is monitored in real time, and the value r is calculated according to the front and rear wheelbase d of different domestic waste cleaning and transport vehicles. min The multiple of is used as the limiting threshold, thereby taking into account the different situations of domestic waste collection and transportation vehicles and determining the turning method of the domestic waste collection and transportation vehicles at each intermediate collection point, thereby avoiding congestion or inconvenience in turning of the domestic waste collection and transportation vehicles at each intermediate garbage collection point.

[0076] 5. After determining that the turning method of the domestic waste cleaning and transportation vehicle at each intermediate garbage collection point is a circular turning method, in order to make the arc turning path the shortest, the total length of the arc turning path is constructed by taking the angle between the next (q+1th) intermediate garbage collection point and the x-axis of the geodetic coordinate system in the plane rectangular coordinate system as a variable. Minimize the model to determine the optimal angle of the x-axis of the geodetic coordinate system in the plane rectangular coordinate system of the next intermediate garbage collection point in the walking path The absolute value is used as a standard to determine whether the angle of the x-axis of the geodetic coordinate system in the plane rectangular coordinate system in the real-time arc turning walking path is greater than the standard, and then the direction of left or right turn is determined, and the walking path and direction are planned to make the overall path of multiple intermediate garbage collection points the shortest, thereby achieving the optimal effect of path planning.

If the circular turning method is used to turn at the intermediate garbage collection point, step S3 is used to further optimize the angle of the domestic garbage collection and transportation vehicle at each intermediate garbage collection point relative to the x-axis of the newly established plane rectangular coordinate system, and then after step S2 determines whether the turn of each intermediate garbage collection point is left or right, the angle with the x-axis of the plane rectangular coordinate system during the turn is further optimized, so that the garbage collection and transportation path is further optimized to the shortest.

[0101] S13: Determine whether the real-time dryness and wetness of the monitored domestic waste is greater than or equal to the humidity threshold within the monitored time period n. If it is greater than or equal to the humidity threshold, classify the domestic waste as subdivided wet waste; otherwise, classify the domestic waste as subdivided dry waste.

[0102] As another preferred embodiment of the present invention, specifically, Figure 3As shown, the method for constructing a real-time subdivided dryness and wetness calculation model for domestic waste in step S12 includes the following steps:

[0103] S121: Construct the dryness coefficient D related to the height L(t) of the domestic garbage from the horizontal plane where the ultrasonic signal emission source point is located. L (t) calculation model and the dryness coefficient D related to the radial distance R(t) from the horizontal plane of the domestic garbage to the central axis of the ultrasonic signal emission source point R (t) Calculation model:

[0104]

[0105]

[0106] Among them, λ1 is the composite density coefficient of dryness of domestic waste, w1 is the total weight of dry garbage roughly sorted and weighed in step S1, and w2 is the total weight of wet garbage roughly sorted and weighed in step S1;

[0107] S122: According to the results calculated in S121, the first household waste dryness and humidity mixing coefficient DH is constructed respectively. L (t) Calculation model and second household waste dryness and humidity mixing coefficient DH R (t) Calculation model:

[0108]

[0109]

[0110] Among them, λ2 is the humidity composite specific gravity coefficient of domestic waste, Q is the polarization mixing coefficient of the ultrasonic signal caused by the wet garbage in the domestic garbage. μ(β(t)) is the refraction coefficient of the ultrasonic signal due to the presence of wet garbage, with an angle of β(t) in the direction of the refraction of the ultrasonic signal at the incident point of the ultrasonic wave. G(θ(t)) is the influence coefficient of the angle θ(t) between the horizontal plane of the ultrasonic incident point of the monitored garbage and the ultrasonic emission source point on the wet garbage detection. G(θ(t)) = λ2 / cos 2 θ(t),

[0111] S123: Construct a calculation model for the dryness and humidity DH(t) of subdivided domestic garbage:

[0112] DH(t)=T(t)[1-(DH L (t)+DH R (t))]e -η +T(t)(1-κ)(1-e -η )[1+e-η (1-(DH L (t)+DH R (t)))]

[0113] Among them, η is the attenuation coefficient of the ultrasonic signal caused by the monitored garbage, η is generally 0.002-0.009dB / (cm·MHz), κ is the reflection coefficient of the ultrasonic signal caused by the monitored garbage, κ is generally 0.05-0.10; and then the real-time dryness and wetness of the subdivided domestic garbage are calculated;

[0114] As shown in Table 1, in step S122, the polarization mixing coefficient Q of polarization caused by wet garbage in domestic garbage has different values ​​when ultrasonic wave transmitting signals have different powers.

[0115] Table 1

[0116] Ultrasonic emission signal power Polarization mixing coefficient Q 1.4GHz 0.01~0.15 5GHz 0.15~0.30 10.7GHz 0.20~0.50

[0117] The method for classifying, cleaning and transporting domestic waste provided by the present invention first monitors the ultrasonic parameter data of domestic waste in real time: the height L(t) of the horizontal plane where the domestic waste is located from the ultrasonic signal emission source point, the radial distance R(t) from the horizontal plane where the domestic waste is located to the central axis of the ultrasonic signal emission source point, the angle θ(t) between the horizontal plane where the ultrasonic incident point of the monitored waste is located and the ultrasonic emission source point, and the angle β(t) between the horizontal plane where the ultrasonic incident point of the monitored waste is located and the refraction direction of the ultrasonic wave by the monitored waste, and then respectively constructs the dryness coefficient D with L(t) and R(t). L (t) and D R (t), then according to D L (t) and D R (t) Calculate the first household garbage dryness and humidity mixing coefficient DH L (t) and the second household waste dryness and humidity mixing coefficient DH R (t), the first household waste dryness and humidity mixing coefficient DH L (t) and the second household waste dryness and humidity mixing coefficient DH R (t) takes into account the polarization mixing coefficient of the ultrasonic signal caused by wet garbage in the domestic garbage, the refraction coefficient μ(β(t)) affected by the refraction angle β(t) of the ultrasonic signal caused by the wet garbage, and the influence coefficient G(θ(t)) of θ(t) on the detection of wet garbage;

[0118] According to the first household garbage dryness and humidity mixing coefficient DH L (t) and the second household waste dryness and humidity mixing coefficient DH R(t), the attenuation coefficient η and the reflection coefficient κ of the ultrasonic signal caused by domestic garbage are integrated, and finally the calculation model of the dryness and humidity DH(t) of the domestic garbage is constructed, and it is judged whether it is greater than the humidity threshold DH thres To subdivide the dryness and wetness of the monitored domestic waste, and calculate the dryness composite specific gravity coefficient λ1 and the moisture composite specific gravity coefficient λ2 of the domestic waste after rough classification and weighing, so as to effectively and accurately judge the dryness and wetness of the domestic waste, avoiding the unclear distinction of domestic waste caused by rough classification, resulting in inaccurate classification in the later stage. When dry waste or wet waste is treated separately in the later stage, if the early classification is inaccurate, resulting in a lot of wet waste mixed in the dry waste, it will cause the treatment process specifically for dry waste to incompletely treat the wet waste, or the treatment process specifically for wet waste to incompletely treat the dry waste, resulting in low efficiency of domestic waste treatment.

[0119] The first household garbage dry-humidity mixing coefficient DH provided by the present invention L (t) and the second household waste dryness and humidity mixing coefficient DH R (t) is the dryness coefficient D related to the height L(t) calculated in step S121 L (t) and the dryness coefficient D related to the radial distance R(t) R (t), and then the two dryness coefficients D L (t) and D R (t) considers the detection factors of the dryness and wetness of the monitored domestic waste caused by the height L(t) of the ultrasonic signal to the monitored domestic waste and the radial distance R(t) from the central axis of the ultrasonic signal emission source point on the horizontal plane where the domestic waste is located, thereby improving the accuracy and comprehensiveness of the final constructed detailed dryness and wetness calculation model DH(t).

[0120] In the method for sorting, cleaning and transporting domestic waste provided by the present invention, a first domestic waste dryness and humidity mixing coefficient DH is adopted, which takes into account the composite specific gravity coefficient λ1 of the domestic waste dryness at each time point within the total time n monitored in real time, the composite specific gravity coefficient λ2 of the humidity, the polarization mixing coefficient of the ultrasonic signal caused by the wet waste, the ultrasonic refraction coefficient μ(β(t)) that should be absorbed by the refraction angle β(t), and the influence coefficient G(θ(t)) of the angle θ(t) between the emission direction at the ultrasonic incident point and the horizontal plane. L (t) and the second household waste dryness and humidity mixing coefficient DH R (t) The humidity threshold DH caused by the calculated average value and the temperature at each monitoring time point thresTherefore, the humidity threshold also changes dynamically with various influencing factors and the total monitoring time, thereby more effectively determining the humidity threshold of different environmental factors and the monitored garbage conditions, and effectively dividing the monitored garbage into a measurement scale for the subdivision of domestic garbage mixed with dry garbage and wet garbage, avoiding misjudgment when subdividing dry and wet garbage when the temperature threshold is only at one point value.

[0121] As another preferred embodiment of the invention, Figure 4 As shown, in the method for classifying, cleaning and transporting domestic waste provided by the present invention, during the process of cleaning and transporting waste by a domestic waste collection vehicle, a plurality of intermediate waste collection points will be passed. At each intermediate waste collection point, a straight line connecting route between points can be used to travel, or a curved arc walking route can be used to pass through each intermediate waste collection point, such as Figure 5 As shown, step S2 in the method provided by the present invention comprises the following steps:

[0123] S22: Calculate Figure 6 As shown, the total distance D between the starting point and the target end point of the domestic garbage cleaning and transportation vehicle toatal :

[0124] S23: According to the diameter of the domestic waste collection and transportation vehicle, the minimum turning circle radius r of the domestic waste collection and transportation vehicle at the intermediate waste collection point is limited min : Wherein, d is the front and rear wheelbase of the domestic waste cleaning and transport vehicle;

[0125] S24: If the total distance D between the starting point and the target end point of the household garbage cleaning and transportation vehicle calculated in step S22 is toatal ≥50r min , then the domestic waste cleaning and transport vehicle uses an arc turning path at the intermediate garbage collection point; if the total distance between the starting point and the target end point of the domestic waste cleaning and transport vehicle calculated in step S32 satisfies the following conditions: 30r min <D total <50r min , the domestic waste collection and transportation vehicle adopts a straight-line turning path at the intermediate garbage collection point.

Then calculate the value r based on the front and rear wheelbase d of different domestic garbage cleaning and transportation vehicles min As the threshold, 50 times r min As a criterion for whether to use the arc turning method to turn at each intermediate garbage point, the walking path is judged, and 30 times the r min As the minimum limit for straight-line turning at each intermediate garbage collection point, it effectively considers the minimum turning radius r required by the front and rear wheelbases of different types of domestic garbage collection and transportation vehicles if circular turning is adopted at each intermediate garbage collection point. min , and then the total distance required for the circular turning method of each intermediate collection point is calculated by the minimum turning radius r min Then the total plane Euler distance D between the starting point and the target end point is determined. toatal With the judgment standard 50r min For comparison, if D toatal ≥50r min , it indicates that the domestic garbage collection and transportation vehicles are suitable for the following use at the intermediate garbage collection points: Figure 7-11 If you walk along the arc turning path shown in the figure, at 30r min <D toatal <50r min range, you can choose a straight-line turning path, that is, do not use the circular turning method as shown in Figure 7-11.

Then, the optimal angle between the turning direction of each intermediate garbage collection point and the x-axis direction of the plane rectangular coordinate system and the geodetic coordinate system is obtained. After reinforcement learning of this model, for the domestic garbage cleaning and transportation vehicle controlled by this method, the included angle α between the travel direction of the q+1th intermediate garbage collection point obtained by real-time monitoring and the x-axis direction of the geodetic coordinate system in the plane rectangular coordinate system is q+1 The absolute value of |α q+1 |Absolute value of the angle with the optimal angle Comparative judgment analysis is performed to determine whether the turn at the q+1th intermediate garbage collection point is a left turn or a right turn, and the total length of the arc turning walking path from the qth intermediate garbage collection point to the q+1th intermediate garbage collection point The shortest total length of the walking path of the entire arc turning method from the starting point to the target end point Shortest.

[0155] As another preferred embodiment of the present invention, Fig.12 As shown, in step S3, the garbage collection and transportation path of the domestic garbage collection and transportation vehicle is further optimized to the shortest possible level, including the following steps:

[0156] S31: According to the left or right turn direction of each intermediate garbage collection point determined in steps S201-S205, the domestic garbage cleaning and transportation vehicle turns in an arc, and monitors in real time the angle α between the direction of travel of each intermediate garbage collection point and the x-axis of the geodetic coordinate system in the plane rectangular coordinate system j As initial value, j = 2, 3, ... m-1;

To correct the angle update value of each intermediate domestic waste collection point That is, the angle update value of each intermediate domestic waste collection point is used Repeat steps S31-S34 as the initial value of step S31 to optimize the angle between the path direction of each intermediate domestic waste collection point and the x-axis of the geodetic coordinate system in the plane rectangular coordinate system, and then select the direction of the circular turning mode as left turn or right turn in steps S201-S205 of step S2, so that the total path length of the circular turning mode turning path is The shortest total length of the walking path for the entire arc turning method In the shortest case, the variables that affect the total length of the arc turning path are further analyzed from the perspective of accuracy: the angle α between the jth intermediate garbage collection point and the x-axis of the geodetic coordinate system of the plane rectangular coordinate system j , and further optimize the garbage collection and transportation routes of domestic garbage collection and transportation vehicles in the shortest possible time.
