Description

TECHNICAL FIELD

[0001] The present specification relates to the field of environmental protection, in particular to a garbage can with voice and visual auxiliary classification and throwing function. BACKGROUND

[0002] In the past, due to the lack of awareness of garbage classification, people often mixed all garbage together and threw it away. This practice has many drawbacks, not only wasting recyclable resources, but also increasing the cost of garbage disposal. If the garbage can be properly handled, the value contained in it is enormous.

[0003] With the acceleration of urbanization, the number of urban residents has increased dramatically, leading to the following challenges for the management department in promoting garbage classification policies. Due to the large number of regional residents, the management department is difficult to cover comprehensively, resulting in omissions in the setting of garbage classification throwing points and insufficient supervision, which not only affects the daily life of residents, but also weakens the implementation effect of the garbage classification policy. In addition, the fixed-time and fixed-point garbage throwing system does not fully consider the actual needs of the working population at different time periods, causing inconvenience. At the same time, the breaking of bags during the throwing of kitchen waste can easily cause hand pollution, increasing the resistance of residents in the process of garbage classification. The existence of these problems not only affects the effective implementation of the garbage classification policy, but also has a negative impact on the quality of life of residents. How to make up for the management shortcomings and achieve the goal of both reasonably solving the actual difficulties of a large number of residents and conveniently and accurately improving the work efficiency of the management department has become a key problem that needs to be solved for community management and resident users.

One skilled in the relevant art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures and functions have not been described in order to avoid obscuring the application.

[0033] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0034] Referring to Figures 1-6 The present application provides an environmentally friendly community garbage can with voice and visual auxiliary classification and dispensing functions, comprising a voice and visual capture board 1, a clamping groove outer box 5, an open-pull inner box 6, and a solar panel 9. The voice and visual capture board 1 is vertically connected between the clamping groove outer box 5 and the solar panel 9, and a camera 3 is installed in the middle of the voice and visual capture board 1. A microphone 2 and a loudspeaker 4 are respectively installed on both sides of the camera 3. The clamping groove outer box 5 has eight clamping grooves 7, which are divided into four groups every two. A dispensing opening 16 and a sliding cover plate 17 are provided on the top. The open-pull inner box 6 has two grooves 8 at the bottom, and the back plate 13 can be rotated. A rotating handle 14 is installed on the left side. The solar panel 9 is arranged at the top at an angle of 60° with the horizontal line. A single-crystal silicon solar panel 15 is embedded in the middle of the solar panel 9, and is electrically connected with a lithium battery replacement compartment 11 at the lower left side of the clamping groove outer box 5. Replaceable lithium batteries 10 are stored in the compartment. The lithium batteries 10 are electrically connected with the inside of the voice and visual capture board 1, and supply power to the camera 3, the microphone 2, and the loudspeaker 4.

[0035] The voice and visual capture board 1 is vertically placed, and the camera 3 arranged in the middle is 1.3 m away from the bottom of the card slot outer box 5, and cooperates with the microphones 2 and loudspeakers 4 on the left and right sides to control the front and back sliding of the sliding cover plate 17. At the most common garbage disposal height, the sound and action of the disposal user are accurately captured, so as to control the opening and closing of the garbage can.

[0036] The card slot outer box 5 is internally uniformly transversely arranged with four garbage can cavities 18 of the same size and a lithium battery replacement bin 11, and each garbage can cavity 18 is provided with two card slots 7 at the bottom, and the size and shape of the card slot 7 are consistent with the size of the recessed space of the pull-out outer box groove 8. When the top sliding cover plate 17 slides forward to the top of the cavity, it can completely cover and close the disposal opening 16. It is convenient to replace the garbage can and lithium battery.

[0037] The pull-out inner box 6 is provided with four, and the back plate 13 is designed to be pull-out rotation with the frame rod 12 as the shaft, and the left rotating handle 14 at the back is pressed to realize the opening and closing of the box. The pull-out design allows the system to be emptied without the need for overall replacement, but to directly replace the garbage bag at the back, reducing the workload of the staff, so as to more efficiently manage and clean.

[0038] The lithium battery replacement bin 11 is located at the leftmost bottom of the card slot outer box 5, and is internally hollow, and electrically connected to the monocrystalline silicon solar panel 15 and the voice and visual capture board 1. The solar energy charges the lithium battery, and the lithium battery is chargeable and replaceable to ensure the continuous power supply of the system, while achieving the effect of energy saving and emission reduction.

[0039] The camera 3 is designed to cope with weak light scenes such as rain, fog, haze or night. The target detection algorithm first performs weak light enhancement preprocessing, then uses Gaussian filter to smooth the image and remove noise, calculates the gradient amplitude and direction of the image, performs non-maximum suppression on the gradient amplitude, detects potential edge regions within the double threshold and retains them, and finally uses morphological dilation operation and connected component labeling algorithm to further extract the geometric features of the region, and selects the region that meets the target shape. In order to ensure the capture of the disposal action in weak light environment such as fog, overcast or night.

[0040] The visual auxiliary system and the voice auxiliary system work in coordination. When a primary wake-up word is heard, the password mode is added, the system calls the camera 3 to detect the garbage target, and controls the sliding cover plate 17 to work to completely open the disposal opening 16. At this time, the visual auxiliary system enters the listening state, the camera 3 continues to work, and when the target disappears, the sliding cover plate 17 is controlled to work to completely cover the disposal opening 16. It can timely accept and feedback the type of garbage, so as to work in coordination with the visual auxiliary system.

[0041] Working principle: when using an environmentally friendly community garbage can with voice and visual auxiliary classification and delivery function, first according to Figures 1-7 The operation process of the environmentally friendly community garbage can is based on the cooperative work of the voice and visual auxiliary classification and delivery system. The system is composed of a camera 3, a microphone 2 and a loudspeaker 4, and uses an LD3320 voice recognition module and a visual detection algorithm for intelligent control. The core part of the device is the voice and visual capture board 1, which is installed with a camera 3 in the middle, and a microphone 2 and a loudspeaker 4 on the left and right sides, respectively, for capturing sound instructions and visual information. The voice and visual capture board 1 is vertically installed between the card slot outer box 5 and the solar panel 9, and is electrically connected to the lithium battery replacement compartment 11 for power supply, ensuring the normal operation of the system.

[0042] When the device is in standby state, the system is maintained in low power consumption mode, and the user's voice input is listened through the microphone 2. When the user utters the set wake-up word "start", the LD3320 voice recognition module starts into password mode, and the control system of the camera 3 and the sliding cover plate 17 is activated. The system controls the mechanical movement of the four garbage can doors through an 8-way relay, realizing intelligent management of garbage classification. The camera 3 starts working and captures the user's delivery behavior, and at the same time performs image preprocessing, including weak light enhancement, Gaussian filter denoising, gradient amplitude calculation, non-maximum suppression, double threshold detection, morphological dilation operation and connected component labeling algorithm, etc., to ensure that the garbage type and position can still be accurately identified in weak light scenes such as rain, fog or night. After detecting the target garbage object, the system controls the sliding cover plate 17 to slide along the card slot 7 to the fully open state through the intelligent control of the sliding cover plate 17, exposing the delivery port 16 and allowing the user to deliver garbage. Four garbage can cavities 18 of the same size are distributed inside the card slot outer box 5, and two card slots 7 are arranged at the bottom of each cavity, matched with the grooves 8 of the open-pull inner box 6, so as to accommodate and fix the garbage can. When the user finishes the delivery, the camera 3 continues to work to detect the disappearance of the target object.

[0043] When the garbage delivery is completed, the system automatically controls the sliding cover plate 17 to slide forward to cover and close the delivery port 16, preventing external pollutants from entering. In order to ensure the stability and long-term work of the system, a single crystal silicon solar panel 15 is designed at the top of the device, installed in the solar panel 9 and at an angle of 60° with the horizontal line to optimize the light absorption efficiency. The solar panel 15 is electrically connected with the lithium battery replacement compartment 11 to provide sustainable power supply for the device. The lithium battery replacement compartment 11 is located at the bottom left side of the card slot outer box 5, and the inside is hollow for storing replaceable lithium batteries 10, and the positive electrode 20 and negative electrode 21 sockets are located at the top of the battery for easy replacement and maintenance.

[0044] After completing the garbage disposal and classification work, the user can close the system through the voice instruction "shutdown" to make the device enter the low-power standby mode, so as to save energy and improve the service life of the device. The whole system can efficiently complete the whole process of garbage classification and disposal through the cooperation of voice and visual auxiliary classification and disposal system, and ensure the continuous and stable operation of the device through the design of solar power supply and replaceable lithium battery.

[0045] The same and similar parts among the various embodiments in the specification can be referred to each other, and each embodiment focuses on the difference from other embodiments. Especially, for the method embodiments described later, since they are corresponding to the system, the description is relatively simple, and the relevant parts can refer to the part of the system embodiment.

[0046] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
