Description
Technical Field
The invention belongs to the field of garbage classification.
Background
Along with the increase of population and the acceleration of urban and rural integrated footsteps, urban population is more and more concentrated, living habits and environments are greatly changed, and along with the increase of the accumulation of household garbage, the household garbage is treated into things which are closely related to our lives. According to data of 'Chinese city construction statistics yearbook' issued by the Ministry of civil engineering in 2018, the clear and transported quantity of domestic garbage in China rises year by year in 2010, wherein 2016 exceeds 2 hundred million tons and reaches 2.04 hundred million tons, and the year-by-year increase is 6.81%; 2017 reaches about 2.16 ten thousand tons, and the increase is 5.82 percent.
Under the background, the statistics, the treatment and the classification of the quantity of the garbage are very important, and the quantity of the garbage in the garbage can cannot be monitored at any time due to the fact that the existing garbage can in the market has no monitoring system, so that the garbage can is pulled away by a garbage collection vehicle to dump sometimes when the garbage can is not full. This wastes the public resources of society to some extent. Such as manpower, material resources, and financial resources. And the strict monitoring of the garbage quantity can more accurately count the garbage quantity, and then analyze the corresponding problem through big data statistics. Countermeasures are found as soon as possible. And the environmental pollution is reduced. Contributes to the greening of the earth.
Because traditional dustbin does not have the positioning mechanism, rubbish recovery car driver can perhaps come back to the dustbin around unnecessary way sometimes, and in addition, the location technique can also effectually prevent that the dustbin from suffering accidents such as destroying, moving and even stealing.
The main bright spot on this product lies in the vision technique on the dustbin, and he can assist waste classification, and when the people who will throw away rubbish did not know what rubbish belongs to of oneself, can use vision classification technique help people to distinguish the rubbish type fast, lets rubbish get back to the position of oneself. Improving the environmental protection will of people.
The automatic cover opening (closing) technology on the dustbin ensures that the peculiar smell of the dustbin can not fly everywhere, frees the hands of people, does not touch polluted places under the condition that the shadow of the current new crown still exists, and indirectly blocks a way of possibly infecting the new crown.
The automatic closing and sealing type dustbin can prevent the rubbish from being exposed to the air, thus indirectly beautifying the city.

the single chip microcomputer controller controls a corresponding motor (9), the motor (9) drives an elliptical far-end point (10.1) of an elliptical control wheel (10) to move to a second action lever (8.1) pressing a second microswitch (8), the second microswitch (8) feeds a signal back to the single chip microcomputer controller after being pressed, then the single chip microcomputer controller sends an instruction of locking the motor (9), the motor stops moving, and at the moment, according to the transmission relation, a corresponding movable feeding door (6) is just in a closed state;
a control method when the person throwing the garbage knows what type of garbage is thrown;
the person throwing the garbage automatically walks to the front of the corresponding garbage bin cabinet (1), the first photoelectric switch (4) at the front side of the corresponding garbage bin cabinet (1) recognizes that a person approaches, signals are fed back to the single chip microcomputer controller, and then the single chip microcomputer controller independently controls a movable feeding door (6) in front of the person throwing the garbage to be automatically opened for preset time;
a control method when the person throwing the garbage does not know the type of the garbage thrown;
at this time, a person who throws the garbage spontaneously takes the garbage to be thrown in front of the lens of the visual camera (102), the third photoelectric switch (999) recognizes that an article is arranged at the lens of the visual camera (102), the controller starts the visual camera (102), and the visual camera (102) acquires garbage image data at the lens; then, the collected images are subjected to image processing such as enhancement, denoising and threshold segmentation, the planar image distortion of the garbage formation image is corrected through a calibration and compensation algorithm, the image of each plane is segmented, the images of the same plane collected by a left camera and a right camera of the same garbage formation image piece are spliced together from the central equator position of the garbage formation image to obtain an image with a complete plane, parameters such as gray level, RGB or HSV, texture and the like are extracted, and the image characteristics of the garbage formation images with different sizes are distinguished through a three-dimensional modeling method, so that the garbage type is obtained; then controlling a loudspeaker (101) to broadcast to a person throwing the garbage, and finally, the person throwing the garbage walks to the front of the corresponding garbage bin cabinet (1) according to the instruction of the loudspeaker, and at the moment, the corresponding movable feeding door (6) is automatically opened for a preset time;
the method for monitoring and controlling the garbage amount of each garbage bin cabinet (1) comprises the following steps:
when the garbage accumulation amount of a garbage can (2) of garbage in a garbage can cabinet (1) reaches the preset highest height, the second photoelectric switch (14) recognizes that the corresponding garbage can (2) is full of garbage, and then the second photoelectric switch (14) is switched on; then the singlechip controller receives a signal sent by a second photoelectric switch (14), and the singlechip further processes information and feeds the garbage condition of the current garbage can back to the garbage station by using a wireless communication module; meanwhile, the single-chip microcomputer controller controls a motor (9) corresponding to a garbage can (2) filled with garbage, the motor (9) drives an elliptical far-end point (10.1) of an elliptical control wheel (10) to move to a second action lever (8.1) which just presses a second microswitch (8), at the moment, according to the transmission relation, a corresponding movable feeding door (6) is just in a closed state, and the controller controls the corresponding motor (9) to be locked; therefore, the movable feeding door (6) corresponding to the full garbage can (2) is forcibly locked, and the garbage is effectively prevented from overflowing.
