Description
Technical Field
The invention relates to an intelligent garbage classification method and an intelligent garbage classification processing system for completing garbage classification by using the method.
Background
The garbage classification is an important ring of garbage recycling, the accurate classification can greatly save the cost of garbage recycling treatment, improve the garbage treatment efficiency and the garbage utilization rate, and the state is greatly pushing the garbage classification at present, however, the resistance for pushing the garbage classification is huge, and the reason is that the knowledge popularity of the garbage classification in the masses is insufficient and the awareness of the garbage classification is lower; secondly, the garbage classification rules are not completely the same due to different garbage treatment capacities of different cities, so that the popularization of garbage classification knowledge in the public and the cultivation of garbage classification consciousness are more difficult; thirdly, if the garbage classification rule is changed due to the improvement of garbage disposal capability, new knowledge is popularized again in the people and new habits are developed, which clearly means huge cost and time expenditure.
In order to solve the above problems, patent CN 109969639A and CN 109516037A propose schemes for identifying garbage by machine vision and helping users to classify, but the types of garbage that can be classified are limited by solely acquiring image information of garbage by machine vision.
The problems and the disadvantages of the prior art are that firstly, a clear garbage classification system structure is not defined, secondly, the design of the garbage classification system is not modularized, the requirements of the garbage classification occasions on the number, the form and the kind of the garbage storage modules and the data acquisition modules are different, and the non-modularized design cannot adapt to changeable application scenes; thirdly, the image acquired by the camera is not fused with the information acquired by other sensors by using an information fusion technology, and is identified by using a relevant technology (such as a deep neural network identification technology) related to machine vision, so that the acquired and utilized information is limited, and the garbage types and the upper limit of classification performance which can be classified by the system are limited; fourth, all schemes do not describe a protection method of user privacy, which is very important in intelligent classification, especially in a household intelligent garbage classification system, and is a necessary means for ensuring user information security.
In addition to the above drawbacks, the conventional trash recognition device has the following drawbacks:
the first, garbage identification device is relatively costly.
Because the key CPU and the integrated CPU are needed by the garbage identification device, and various information of image, sound and metal detection obtained by the sensor of the garbage identification device are identified, a relatively high CPU calculation chip is required to complete operation, and therefore, a CPU calculation chip and a calculation circuit main board with higher cost are required, and the cost of the garbage identification device is very high. For example, to achieve a CPU calculation chip and a calculation circuit main board for classifying thousands of kinds of garbage which may be generated in daily life normally, at the current production cost, at least 1000-2000 Yuan Renzhen, and the garbage recognition device equipped with the CPU calculation chip and the calculation circuit main board has an overall cost of at least 3000 Yuan Renzhen after other structures are included. Therefore, the price is a small burden for most families in China, and the device is difficult to popularize to most families in China.
Secondly, although the user has already classified the garbage at his home, when he packs the obtained classification and mentions the garbage transfer station (for example, when the user mentions the garbage which has already been classified at home to the garbage classification transfer station of the district), the garbage classification transfer station of the district needs to classify the garbage provided by the user again, and then the user is allowed to put the garbage provided by the user into the corresponding garbage can of the district transfer station, during which the user needs to wait for the district transfer station to complete classification analysis of the garbage, and the user can normally put the garbage.
For example, when a user lifts two garbage bags with cans and paper scraps, which are classified, to a garbage transfer station in a district, the garbage transfer station in the district needs to identify the two garbage bags again, whether the two garbage bags are identified manually or automatically by a computer system, and each garbage bag needs to take at least 50 seconds. Therefore, a garbage is classified and identified twice, not only is the resource waste and the energy waste caused, but also the energy and the time of the user can be occupied when the garbage is classified again, and bad experience is caused for the garbage loss of the user.
Meanwhile, in the garbage classification system, garbage data recording equipment (such as a camera, a metal sensor and the like) is designed to be independent equipment or is arranged on a recycling system such as a garbage can, so that a user needs to place garbage in a specific area to finish data recording when putting garbage in the garbage classification system, and recognition is waited to finish, which clearly increases waiting time and waiting anxiety of putting garbage in the garbage by the user and seriously influences user experience.
Therefore, there is a need for a more rationally designed garbage classification method, and an intelligent processing system that can accomplish the garbage classification method.

The computer referred to herein is a single-chip microcomputer, and the CPU processor (computer) is a central processing unit of the single-chip microcomputer chip, and is mainly used for completing arithmetic or logic operation of data, and simultaneously coordinating and managing the operation of the whole single-chip microcomputer chip system.
The single chip microcomputer is also provided with a storage area for storing data and programs, wherein the data storage area is used for storing intermediate results of the data, finishing functions of data temporary storage, data buffering and the like, and the storage area of the single chip microcomputer chip is generally divided into an on-chip storage area and an off-chip storage area, wherein the on-chip storage area can be divided into a read-only memory for storing the programs and a random access memory for storing the data. The off-chip memory is an extension of the on-chip memory and may be implemented by an erasable programmable read-only memory, an electrically erasable programmable read-only memory, or the like.
When the data management module works, the CPU (computer) for calculating the data firstly performs block compression on the data to be stored before the data is stored, then stores the data in the storage space of the computer, firstly decompresses the instructions in the storage space before executing the instructions in the storage space, and then provides the decompressed instructions for an external chip of the singlechip chip for processing. The function of performing block compression on instruction data may be performed by a compiler external to the monolithic chip, and the function of performing decompression may be performed by a processor internal to the monolithic chip.
After the processor of the singlechip chip finishes executing the current instruction, the processor judges whether the next instruction to be executed is positioned in the address range associated with the current instruction; if yes, the processor continues to execute the next instruction in the address range of the current instruction; if not, the processor extracts the corresponding instruction from the storage space again, decompresses the instruction, and then executes the instruction after solving the shrinkage.
And a data recording module: and acquiring data of the garbage to be classified through a sensor.
The data recording module is also arranged on the wearable device, such as a smart watch and a bracelet. The intelligent watch and the bracelet can be provided with a plurality of sensors, the types of the sensors comprise cameras, and the sensors can also comprise metal detectors, distance sensors and other types of sensors (infrared image cameras, microwave radar, laser radar detection data, X-ray imaging data and the like) according to the types of garbage to be classified and the needs of scenes, and the data recording module also comprises an illumination system to help the cameras to acquire images of the garbage to be classified more accurately; the triggering condition of the illumination subsystem is that the distance between the garbage and the camera is within a certain range, a ranging module (the specific ranging mode can be ultrasonic ranging, infrared ranging, laser ranging or radar ranging and the like) is arranged beside the camera, the distance between the garbage and the camera is measured, and when the distance is within a set range, the camera and a flash lamp are turned on to obtain an image.
The smart watch and the bracelet can be provided with partial sensors according to the needs and the implementation difficulty, but at least should be provided with: camera, distance sensor, illumination subsystem, range finding module, sound recording (microphone).
The metal detector adopts an all-metal detector: all metal impurities of different materials can be detected, and the current market share of the metal detector is highest. The alarm device of the existing all-metal detector is electrically connected to the data recording module of the invention, when metal is detected, the alarm current sent out is received into the data recording module to generate an analog signal quantity, and the data processing module marks the analog signal quantity as a metal label.
The method for acquiring images and processing data by using the camera is mature in the current technology.
According to the different processing capacity and the different recording scenes, the means of data recording are two types, one type is that a data recording module continuously records a plurality of groups of data, and garbage data which is favorable for the identification of a server is selected and transmitted to the server; the other is to use technical means to guide the user to create favorable conditions for recording the garbage data which is favorable for the server to identify, for example, a distance sensor is arranged beside a camera to measure the distance of the garbage, when the distance of the garbage is positioned in a preset distance section, the user is prompted by means of optics, acoustics or combination of the optics and acoustics, the data recording conditions are met currently, the data is recorded, the recording action refers to multiple times of measurement on the same target, and multiple groups of data of the same target are recorded.
The data recording module transmits the recorded data to the data management module. The method involves data conversion, or data conversion is carried out by a digital recording module or obtained data is converted by a data management module, and the realization method is as follows through a data conversion circuit: the data conversion circuit, a device that converts an analog quantity into a digital quantity, is called an analog-to-digital converter, and is simply called an a/D. The a/D conversion process is completed through 4 steps of sampling, holding, quantizing and encoding, which is called an analog-to-digital converter, and when the a/D conversion is finished, the ADC outputs a conversion finish signal data. The CPU can read the conversion result in a variety of ways: (1) a query mode; (2) an interrupt mode; (3) DMA mode. The present invention may employ CMOS components with 8-bit a/D converters, 8-way multiplexing switches, and microprocessor compatible control logic. The successive approximation type A/D converter can be directly connected with a singlechip. The system consists of an 8-way analog switch, an address latch and decoder, an A/D converter and a tri-state output latch. The multi-way switch can gate 8 analog channels, allows 8 analog quantity to be input in a time sharing way, and is used for conversion by the common A/D converter. The tri-state output latch is used for latching the digital quantity after A/D conversion, and the converted data is taken out from the tri-state output latch.
In the practical system, various physical parameters (such as pressure, electromagnetic induction, sound and the like) are measured by a sensor and converted into electric signals, and then the electric signals are transmitted to a CPU of a computer through an A/D converter; after the processing of the CPU, the D/A converter is used for controlling various parameter quantities.
The main work of the garbage storage module is to finish garbage storage. The main structure of the garbage storage module is a garbage can, a garbage can cover plate capable of controlling opening and closing, a mechanical structure for controlling the cover plate, a sensor for judging the garbage amount in the can, a garbage compression mechanical structure, an embedded third computer for receiving control instructions, sending a garbage can state communication subsystem and a third communication subsystem for controlling the mechanical structure; the embedded third computer receives the storage instruction sent by the data management module through the third communication subsystem, controls the barrel cover and the garbage compression mechanical structure according to the instruction, and sends the state of the garbage can to the data management module through the third communication subsystem.
The garbage collection module is implemented as follows:
the garbage collection module provides various state data of the garbage can to the man-machine interaction module, and the man-machine interaction module displays various state data to a system user, wherein the data comprise, but are not limited to, statistical data of garbage throwing and residual capacity of the garbage collection module.
The man-machine interaction module can accept data and instructions input by a user, and the content of the man-machine interaction module comprises, but is not limited to, definition of garbage types stored in the garbage storage module and system function setting.
The data management module comprises a second communication subsystem and a second computer, and has the functions of providing display content for the man-machine interaction module, receiving data and instructions input by the man-machine interaction module, controlling various states of the system according to the data and the instructions, and transmitting system data which can be transmitted by the system user authorization to the server so as to ensure the privacy of the user; the method comprises the steps of receiving garbage data to be classified, which is acquired by a data recording module, and transmitting the garbage data to a server to finish identification; receiving the identification result and inquiry and control data and instructions sent by the server, generating a storage instruction according to the identification result, sending the storage instruction to the corresponding garbage storage module, and executing the inquiry and control instructions of the server according to the authorization of the system user.
The server module comprises a high-performance server and a first communication subsystem, and has the functions of identifying the garbage type according to the garbage data to be classified, which is sent by the data management module, and sending the identification result to the data management module; system status is obtained or queried from the data management module, system data is collected and analyzed, and necessary control instructions are generated and sent.
Further, the number of the garbage storage modules and the kinds of garbage stored therein may be defined by a user. The definition of waste is determined based on local requirements for waste classification, e.g. local regulations require classification of waste into kitchen waste and recyclable waste, and the user can only define waste bins into these two categories.
Further, the garbage storage module can pack and bag stored garbage, and after the garbage storage module packs, the district garbage transfer station can identify the garbage bag and throw the garbage bag into the corresponding garbage storage module.
Furthermore, the data management module, the data recording module and the user interaction module can be integrated into a single hardware device in hardware, such as a portable device such as a mobile phone or a wearable device such as a smart bracelet and augmented reality glasses. The server module is cloud computing, and the garbage storage module is a small garbage can with a third computer. The communication modes between the data management module and the server and between the data management and garbage storage modules are 5G networks, and other communication modes with transmission rate higher than 500KB/s, such as 4G, WIFI and Bluetooth, can be adopted under the condition of no 5G. The better choices are: the communication mode between the data management module and the server can select WIFI and 4G/5G networks. And the connection mode between the data management and the garbage storage module can be Bluetooth or WIFI.
The method comprises the steps that a server identifies garbage by deep learning and information fusion (including but not limited to a deep neural network technology), the garbage image is identified by the deep learning, and then the final classification of the garbage is completed by fusing an image identification result and other sensor data by the information fusion technology. Further, the communication between the modules is encrypted communication, and a public key encryption algorithm, such as an RSA encryption algorithm, is adopted, which is that the information receiver generates a pair of public key and private key, sends the public key to the information sender, encrypts the information sent by the public key, and decrypts the encrypted information by the private key.
Server identification garbage adopts deep learning and information fusion modes (including but not limited to deep neural network technology) to identify garbage images, for example:
after the server acquires the image samples, the image samples are input into an original neural network model, and the neural network model suitable for configuration parameter information is obtained through learning training of each network in the original neural network model. According to the neural network model obtained through training of a large number of high-frequency garbage image samples, the image data can be identified rapidly and efficiently when a later user collects the image data. For example, the training process is to preprocess the image sample, extract the image feature vector of the preprocessed image sample by using the DNN feature extraction network, calculate the loss value by using the forward conduction algorithm and the loss function according to the extracted image feature vector and the image label, and optimize the parameters of each layer of DNN by using the backward conduction algorithm.
Further, the data processing module only transmits data transmittable by user authorization to the server to protect user privacy. The user privacy information comprises specific types of garbage in the garbage can, the time for throwing garbage by a user, the quantity of garbage thrown by the user and the statistical data of the three contents, and further comprises photos shot by a camera, distance sensor data, mechanical sensor data and operation records of all modules. The user opens the information transmission authorization settings through the human-machine interface, and the user authorization settings can be transmitted to the information of the server.
The Computer (CPU) involved in the data processing module of the present invention comprises a computer readable storage medium and a computer program mechanism embedded therein, said computer program mechanism comprising instructions for performing the steps of any of the above-described methods.
The above-described parts of the apparatus are described separately in terms of functional division into various modules. The functions of the modules or units may be implemented in the same piece or pieces of software or hardware.

The intelligent garbage classification method comprises the following steps:
firstly, acquiring garbage data to be classified by using a wearable device (hereinafter, an intelligent watch is exemplified, an information recording module is arranged on the intelligent watch), and arranging various sensors on the intelligent watch according to the requirement; the garbage data which can be acquired can be one or a combination of images, sound, metal detector detection data, infrared images, microwave radar, laser radar detection data and X-ray imaging data of garbage; wherein at least an image (picture or video) needs to be obtained.
The invention is mainly used for acquiring image information and mainly acquired through a camera. When other information is incomplete, only the obtained image information may be sent to the data processing module of the present invention, and of course, when only other information (sound, metal detector detection data, infrared image, microwave radar, etc.) is not included, the image information is optimally selected not to be sent to the data processing module of the present invention.
Secondly, a data processing module (also arranged on the intelligent watch) preprocesses the obtained garbage data to be classified; the method mainly refers to preprocessing images of garbage to be classified, and comprises the following steps:
(1) The garbage data acquisition is automatically completed in normal life without the need of the user to do with the watch. However, if some junk data is difficult to acquire, the acquisition is unsuccessful for many times, and the intelligent watch can be manually operated to acquire the junk data. For example: the intelligent watch is provided with a distance meter, the distance between the garbage and the camera is measured through the distance meter, the brightness of a camera light filling lamp is controlled according to the distance, when the garbage is positioned in an ideal data acquisition area, the light filling lamp is brightest, and the intelligent watch sends a 'click' sound to inform the user that the garbage position meets the data acquisition requirement, and the data is being acquired.
After a plurality of images of garbage to be classified are acquired, deleting the images of garbage to be classified, which are unfavorable for intelligent recognition of the server, and re-acquiring a plurality of images when the acquired images of garbage to be classified do not meet the requirements for intelligent recognition of the server, wherein the standards for intelligent recognition of the server are as follows: the expected success rate of the identification of the image by the server is more than 60%; a final selected image is obtained. For example, 10 pictures are obtained through a camera, then screening is carried out on the 10 pictures, from the first picture, if the first picture meets the requirements, the rest 9 pictures are directly deleted, if the first picture does not meet the requirements, the first picture is deleted, the second picture is continuously analyzed, and at least one picture beneficial to intelligent recognition of a server is obtained through flow analysis.
In order to ensure that the identification is more accurate, the success rate of the standard which is beneficial to intelligent identification of the server is improved to 80%; the judging method comprises the following steps: the requirements of the server on parameter values of some items of smoothness, texture, gray scale, color, spectrum characteristics, spatial characteristics, geometric shape analysis, size, color density, spectrum and the like of the photo before recording are superior to the parameter values, namely the server is considered to be identifiable, otherwise, the server is considered to be difficult to identify.
(2) Separating the garbage image from the background from the selected image, wherein the garbage image comprises the following steps:
A. acquiring garbage background data, including the background of a garbage image, the light intensity in the background, the light intensity in the view field of a camera and the like; when the background is static, directly storing the background; when the background is dynamically changed, for example, a moving object such as branches swaying with wind exists in the background, the dynamic background is modeled through a statistical model, the form and parameters of the statistical model (such as Gaussian mixture distribution) are stored, as the background, a data recording module opens a distance sensor and a camera to sense the environment according to a certain strategy, and when the measured distance is found to be changed (meaning that the camera is possibly moved), or the background, the light color, the light intensity and other environmental factors in the view of the camera are changed, garbage background data can be obtained again.
B. Performing target detection on the selected image, and separating garbage from the background to obtain an image only containing garbage;
separating the spam images from the background can increase the spam recognition rate of the server, but not just the essential components of the spam classification system, whether or not this approach is used depends on the processing power of the head-end equipment and the requirements of the server recognition algorithm.
(3) Filtering the collected multiple groups of garbage-only data, filtering out wild values in multiple measurements, and calculating an unbiased estimated value of the measurement based on a statistical model of the data; the accuracy of this unbiased estimate should be higher than the accuracy of a single measurement; and obtaining a high-precision garbage image, finishing preprocessing, and finally obtaining garbage data which is favorable for server identification. The calculation of the unbiased estimate is based on the probability distribution of the data.
At present, more methods for image processing are mature, for example: filtering (smoothing, noise reduction), enhancement, edge sharpening, texture analysis (de-skeletons, connectivity), image segmentation (gray scale, color, spectral features, texture features, spatial features), geometry analysis (Blob analysis) (shape, size, length, area, edges, circularity location, orientation, quantity, connectivity, etc.), blob analysis (number, location, shape, and orientation of blobs in an image can be provided for machine vision applications, and topology between related blobs can also be provided applications: two-dimensional target images, high contrast images, presence/absence detection, numerical range, and rotational invariance requirements), color analysis (chromaticity, color density, spectrum, automatic white balancing). The present invention may utilize some of the above methods for processing or judging background images, garbage images (foreground images).
Thirdly, the data processing module in the intelligent watch sends the junk data which is favorable for the identification of the server to the server, and the server performs intelligent identification to complete the classification judgment of the junk to be classified; the garbage data which is favorable for the identification of the server is sent to the server, specifically, the servers which are in charge of the identification are connected with each other to form a network, each data management module calculates the efficiency index of the server in real time according to factors such as the processing capacity of each server, the task queue condition, the data transmission speed and the like, and the higher the efficiency index is, the faster the identification task speed of the terminal is processed by the server, the data management module entrusts the identification task (garbage data which is favorable for the identification of the server) to the server with the highest efficiency index, so that the optimal identification efficiency is ensured.
The data management module determines the type of data to be transferred according to the processing capacity of the identification server corresponding to the data management module, when the processing capacity of the server is weak, the data management module only transfers static data, such as data composed of static photos and the identification result of the single metal detector, and if the processing capacity of the server is strong, the data management module transfers the time sequence of the static data, such as a section of video composed of a plurality of photos.
Fourthly, the server adopts an information fusion algorithm based on a Bayesian theory to comprehensively process the junk data to be classified; the server sends the information of completing the classification judgment of the garbage to the user, and prompts the user about the classification of the garbage to be classified according to the following steps:
