[0039] Please refer to Figures 1-6 The present application provides a technical scheme: an intelligent garbage can with automatic classification function, comprising a garbage can shell 1 and a garbage guiding assembly arranged inside the garbage can shell 1;The garbage guiding assembly is arranged as an actuator driven by a motor 17 controlled by a controller, the controller is connected with a garbage sensing module, a voice intercom module, a power module, a classification module and a first Wifi data interface, the voice intercom module communicates wirelessly with a distributed mobile terminal through the first Wifi data interface;Wherein the garbage sensing module is an identification camera 4 with sensing capability;

[0040] The garbage guiding assembly comprises a cross plate 18 welded inside the lower half of the garbage can shell 1, a rotating shaft 11 penetrating the cross plate 18 and extending to the upper and lower ends of the cross plate 18, a motor 17 mounted on the bottom of the cross plate 18 through screws, a disc piece 15 fixedly sleeved on the output shaft of the motor 17, a cylindrical piece 16 welded on the disc piece 15, an arc-shaped plate piece 14 welded on the side of the disc piece 15 away from the cylindrical piece 16, a mounting piece 12 fixedly sleeved on the lower end of the rotating shaft 11, the surface of the mounting piece 12 being in contact with the surface of the arc-shaped plate piece 14, four recesses 13 being formed in the surface of the mounting piece 12, the cylindrical piece 16 being in contact with the recesses 13 through the driving of the disc piece 15, and a rotating plate 10 welded on the upper end of the rotating shaft 11.

[0041] The rotating shaft 11 in the garbage guiding assembly is driven by the mounting piece 12 to rotate by 90° each time, so that the rotating shaft 11 can drive the guiding plate 8 to rotate by 90° each time and stop at the corresponding garbage storage barrel 19, and meanwhile, the arc-shaped plate piece 14 is in contact with the mounting piece 12 to limit the movement of the mounting piece 12 during the process that the garbage enters the garbage storage barrel 19 through the guiding plate 8, so that the accuracy of garbage throwing is ensured.

[0042] Moreover, the garbage needs to be placed in the garbage can for a certain period of time, so that the garbage is easy to have an odor, and it is difficult to clean up the garbage after it is splashed out due to the open form. The garbage can shell 1 is a relatively closed shell, so that the garbage is semi-sealedly placed in the garbage can shell 1, thereby avoiding the problem that the garbage is difficult to clean up due to splashing, and the beauty of the surrounding environment of the garbage can shell 1 is ensured.

[0043] The mounting piece 12 is in the shape of a cross, the four recesses 13 are arranged at the four corners away from the axis of the mounting piece 12, and the arc-shaped plate piece 14 can be driven by the disc piece 15 to be in contact with the mounting piece 12.

[0044] The left and right sides of the garbage can shell 1 are both hingedly connected with a hinged door 2, and the upper end of the garbage can shell 1 is provided with a garbage throwing port 3.

[0045] The left and right sides of the upper half inside the garbage can shell 1 are both provided with a sliding groove 6, and the interiors of the two sliding grooves 6 are both provided with an electric push rod 5 through screws.

[0046] Each of the two electric push rods 5 has a movable baffle 7 fixedly installed at its opposite end. The two movable baffles 7 are closed by being pushed by the corresponding electric push rods 5.

[0047] A recognition camera 4 is installed on the upper left side of the inside of the outer shell 1 of the trash can, and the trash disposal port 3 is located directly above the guide plate 8.

[0048] When it is necessary to use this trash can for waste sorting;

[0049] First, external force drives the garbage through the garbage disposal port 3 into the upper part of the two movable baffles 7 inside the garbage bin shell 1. Then, the recognition camera 4 detects and determines the location where the garbage needs to be disposed of. Subsequently, the recognition camera 4 starts the motor 17 to drive the disc component 15 to rotate. The rotation of the disc component 15 drives the cylindrical component 16 to move. The movement of the cylindrical component 16 drives the corresponding groove 13 to move. The movement of the groove 13 drives the mounting component 12 to rotate. The rotation of the mounting component 12 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the rotating plate 10 to rotate 90°. Subsequently, the rotation of the rotating plate 10 drives the two trapezoidal plates 9 to rotate. The rotation of the two trapezoidal plates 9 drives the corresponding guide plate 8 to rotate 90° toward the garbage storage bin 19 to be disposed of.

[0050] Secondly, by activating the two electric push rods 5 to retract, the retraction of the two electric push rods 5 drives the corresponding movable baffle 7 to move and open the garbage disposal port 3, and the garbage falls onto the guide plate 8. Subsequently, the garbage falls into the interior of the corresponding garbage storage bin 19 through the guide plate 8.

[0051] Both sides of the guide plate 8 are provided with baffles. The cross plate 18 divides the bottom space of the trash can shell 1 into four spaces. Four trash storage bins 19 are arranged on the bottom surface of the trash can shell 1. The four trash storage bins 19 are respectively arranged inside the four spaces divided by the cross plate 18.

[0052] It should be noted that: in the initial state, the two movable baffles 7 are in a closed state. When the waste guide plate 8 falls, the arc-shaped plate 14 comes into contact with the mounting piece 12.

[0053] like Figures 7-12 As shown, in the above embodiment, the identification camera 4 with sensing capability includes an image processing module and a sensor group, an infrared detector, and a second Wi-Fi data interface connected to the image processing module. The sensor group includes at least a liquid sensor, a solid-state sensor, a gas sensor, an energy sensor, and a pollution sensor. The sensing process of the identification camera 4 is as follows:

[0054] After the garbage enters the upper end of the movable baffle 7 through the garbage throwing port 3, the identification camera 4 identifies and confirms the type of garbage, and then the controller controls the start of the motor 17 to drive the guide plate 8 to rotate towards the corresponding garbage storage barrel 19, and then the controller controls the two electric push rods 5 to drive the corresponding movable baffle 7 to move in opposite directions, thereby completing the intelligent classification of the garbage.

[0055] This identification camera with sensing capability is a smart device integrated with multiple sensors, and its working principle is as follows:

[0056] Image processing module: This module is the core of the camera, responsible for capturing and processing image data. It converts the light information received by the camera lens into digital signals, and then processes these signals to identify and extract useful information from the image.

[0057] Sensor group: The sensor group is an auxiliary detection unit of the camera, which consists of multiple sensors, each with its specific function: Liquid sensor: used to detect the presence of liquid in the environment, which can be used to identify leaks, humidity or the presence of other liquid substances. Solid-state sensor: used to detect the presence of solid objects, such as metal, plastic, etc., which can help identify different types of garbage or objects. Gas sensor: used to detect gas components in the air, which can be used to monitor harmful gases, smoke or other gas concentrations. Energy sensor: used to detect the presence of energy, such as electricity, heat, etc., which can be used for energy management or safety monitoring. Pollution sensor: used to detect the degree of environmental pollution, such as PM2.5 concentration, chemical pollutants, etc. Infrared detector can detect the infrared radiation emitted by objects, which is usually used for night vision, thermal imaging or object detection. In a smart camera, the infrared detector can enhance image recognition capabilities, especially in low-light environments.

[0058] Second Wifi data interface: In addition to the main image processing and sensor functions, the camera is also equipped with a second Wifi data interface. This interface can be used for: wireless communication with external devices (such as cloud servers, smartphones, etc.), transmission of image data and sensor data. It can also receive remote control instructions, allowing users or systems to remotely control the operation of the camera.

[0059] Comprehensive explanation of working principle:

[0060] When the smart camera 4 is working, the image processing module first captures the environmental image. At the same time, each sensor in the sensor group starts working, collecting data about liquids, solid substances, gases, energy sources, and pollution in the environment. The infrared detector provides additional information, especially in low light conditions, which can assist the image processing module in better identifying objects. The data collected by the sensors combined with the image information analyzed by the image processing module, the camera can more comprehensively identify and classify objects and conditions in the environment. The second Wifi data interface allows the camera to transmit processed data to external systems, while also receiving instructions from external systems, enabling intelligent monitoring and management. Through such comprehensive sensing and data processing capabilities, the smart camera 4 can achieve comprehensive perception and intelligent identification of the environment, suitable for various scenarios such as intelligent garbage recycling, environmental monitoring, security monitoring, etc.

[0061] In a further specific embodiment, the controller is an ARM9 single-chip microcomputer-based controller; the first Wifi data interface and the second Wifi data interface are ESP8266 WiFi modules, and the ESP8266 WiFi module includes a serial circuit, a PWM control circuit, and a GPIO control circuit.

[0062] In a specific embodiment, the controller in this embodiment is an ARM9 kernel-based single-chip microcomputer. ARM9 is a 32-bit Reduced Instruction Set (RISC) processor core, widely used in embedded systems for its low power consumption, high performance, and low cost. ARM9 single-chip microcomputers usually have multiple peripheral interfaces, including timers, ADCs (Analog-to-Digital Converters), UARTs (Universal Asynchronous Receiver-Transmitter), etc., which can communicate with cameras, sensors, and other electronic devices. In this embodiment, the ARM9 single-chip microcomputer serves as the main controller, responsible for coordinating and managing the work of the camera, sensor group, infrared detector, and WiFi module components. It performs the following functions: receives sensor group data, including inputs from liquid, solid, gas, energy, and pollution sensors. Process image data output by the image processing module for image recognition and analysis. According to the sensor data and image processing results, control the classification module to automatically classify garbage or objects. Manage WiFi module communication, including sending and receiving data.

[0063] In this embodiment, the first WiFi data interface and the second WiFi data interface both use ESP8266 WiFi modules. ESP8266 is a low-power WiFi chip that integrates WiFi functionality, allowing devices to connect to WiFi networks.

[0064] The main components of the ESP8266 WiFi module include:

[0065] Serial port circuit: used for communication with ARM9 single-chip microcomputer, transmitting instructions and data through serial data transmission.

[0066] PWM control circuit: Pulse Width Modulation (PWM) is an analog signal control technology, and ESP8266 can use PWM control circuit to control external devices such as LED lights, motors, etc.

[0067] GPIO control circuit: General Purpose Input Output (GPIO) is another important feature of ESP8266, which allows the module to interact with external devices through digital signals.

[0068] In this embodiment, the functions of the ESP8266 WiFi module are as follows:

[0069] First WiFi data interface: used to connect to the main WiFi network, allowing the camera to send image data and sensor data to the cloud server or other devices.

[0070] Second WiFi data interface: can be used as a backup or to connect to different networks, or for local control, such as controlling the camera through a smartphone APP.

[0071] The ESP8266 WiFi module communicates with the ARM9 single-chip microcomputer through its serial port circuit, controls external devices through the PWM control circuit, and reads the status of external devices through the GPIO control circuit.

[0072] Through this configuration, the smart camera 4 can achieve wireless network connection, real-time data transmission, and remote control and management through the WiFi module, improving the flexibility and practicality of the device.

[0073] In further specific embodiments, the controller is controlled based on an ARM9 single-chip microcomputer. The ARM9 single-chip microcomputer has excellent performance, with high operating frequency, capable of quickly processing various complex data operations and instruction execution tasks, ensuring the timeliness of the entire system response. Its rich internal resources, such as multiple General Purpose Input Output interfaces (GPIO), timers, and interrupt controllers, can easily connect and control a variety of external devices, laying the foundation for the diversification of system functions. At the same time, the ARM9 single-chip microcomputer is stable and reliable, and can adapt to more complex working environments, greatly reducing the error probability during system operation.

[0074] The first and second Wifi data interfaces both adopt ESP8266 WiFi modules. The serial circuit in the module plays a crucial role, which is responsible for realizing data transmission with external devices, such as host computers or other serial communication devices. Through standard serial communication protocols, data can be stably and quickly transmitted and received, whether it is transmission control instructions or feedback device status information, which can be accurate and error-free.

[0075] The PWM control circuit provides flexible power regulation function for the system. For example, when connecting some peripherals with special power supply requirements, the PWM control circuit can accurately output pulse signals with different duty cycles according to the requirements, and then regulate the power supply voltage of the peripherals, realizing fine adjustment of the device working state, such as brightness, speed, etc., to meet various application scenarios.

[0076] The GPIO control circuit further expands the functional boundaries of the ESP8266 WiFi module. With these GPIO pins, various digital or analog devices such as sensors, indicator lights, relays, etc. can be connected. When environmental data needs to be collected, connect the corresponding sensor and quickly read the data into the module through the GPIO pin; when the control signal needs to be output externally, the relay and other execution elements can be quickly driven to complete operations such as switch control, device start and stop, etc., fully improving the interactive ability and automation level of the system.

[0077] In further specific embodiments, the classification module is a classification module control module based on a dial switch circuit.

[0078] The classification module adopts a design based on a dial switch circuit, and its working principle is unique and ingenious. As the core component, the dial switch is a manually operated switch combination, each dial switch usually has different gears, representing different binary values.

[0079] At the beginning of system operation, the operator manually adjusts the dial switch to the corresponding position according to the pre-set classification rules. For example, when the system needs to distinguish different types of input signals, such as monitoring data from different sensors, or classify and select different device operation modes, by adjusting the gear combination of the dial switch, a specific code can be generated. These codes are input as control signals to the subsequent circuit.

[0080] From the circuit level, the different positions of the DIP switch are connected to corresponding pull-up or pull-down resistors. When the switch is set to a specific position, the circuit generates a corresponding high or low level signal. These discrete level signals are combined into binary codes, which are recognized by the decoding circuit in the classification module. The decoding circuit converts the binary codes into classification instructions that the system can understand based on the pre-set decoding logic, and then controls the data flow, triggers the operation of specific function modules, or adjusts the parameter configuration inside the system to accurately adapt to different working requirements, achieving efficient and reliable classification control.

[0081] In this way, the classification module based on the DIP switch circuit gives the system flexible and variable classification control ability with a simple and intuitive manual operation method, greatly improving the adaptability of the system in complex task scenarios.

[0082] In the utility model, the classification module adopts a control module based on a DIP switch circuit, and the following is a further explanation of its working principle:

[0083] The DIP switch circuit is a simple digital input circuit composed of a series of DIP switches. Each switch can be set to a connected or disconnected state, corresponding to a specific binary value. In the classification module, the DIP switch circuit is used to convert different types of garbage information detected by the sensor into controllable signals to control the mechanical classification mechanism of the garbage can for garbage classification.

[0084] The following is the working principle of the DIP switch circuit in the classification module:

[0085] 1. Sensor detection:

[0086] The sensor group (including liquid sensor, solid-state sensor, gas sensor, energy sensor and pollution sensor) detects the type and characteristics of the garbage.

[0087] For example, when the liquid sensor detects that the garbage is liquid, it will output a signal; when the solid-state sensor detects metal garbage, it will also output a signal.

[0088] 2. Signal conversion:

[0089] The output signal of each sensor is converted to the corresponding binary code by the DIP switch circuit. For example, the liquid sensor may correspond to binary code "0", while metal garbage corresponds to "1".

[0090] Each position of the DIP switch represents a binary bit, usually with 2^n switches (where n is the number of switches), which can represent 2^n different states.

[0091] 3. Signal input:

[0092] The dial switch circuit inputs the converted binary code into the control module of the sorting module.

[0093] The control module is usually a microcontroller or single-chip microcomputer that can read these binary codes and perform corresponding operations.

[0094] 4. Control sorting:

[0095] The control module determines the type of garbage according to the input binary code and controls the action of the mechanical sorting mechanism.

[0096] For example, if the control module receives a "0" signal, it may activate a channel to send liquid waste into the liquid waste collection tank; if it receives a "1" signal, it may activate another channel to send metal waste into the metal waste collection tank.

[0097] 5. Feedback and adjustment:

[0098] The sorting module may also include a feedback mechanism to make real-time adjustments during the sorting process. For example, if the action of the mechanical sorting mechanism leads to sorting errors, sensors may detect abnormalities and feedback to the control module through the dial switch circuit to adjust the sorting strategy.

[0099] In this way, the dial switch circuit-based sorting module can convert complex sensor signals into simple control signals to achieve automatic sorting of garbage. This method is simple, reliable, and low-cost, suitable for simple garbage sorting scenarios. However, for more complex sorting requirements, more advanced digital signal processing and control logic may be required.

[0100] As Figure 12 shown in the voice recognition part schematic diagram, the LD3320 data manual published by ICRoute was referred to for design. LD3320 integrates fast and stable optimization algorithms internally, without external Flash, RAM, and the need for user pre-training and recording to complete non-specific voice recognition, with high recognition accuracy. The main controller is an STM32F103C8T6 chip from ST. Based on ARM Cottex-M3 32-bit RISC core, the chip has a maximum working frequency of 72MHz, with built-in high-speed memory (64 KB flash memory and 20 KB SRAM)

[0101] LD3320 adopts a parallel mode to directly interface with STM32F103C8T6, both using 1kΩ resistors for pull-up, A0 is used to determine whether it is a data segment or an address segment; control signals RDB, WRB, CSB, reset signal RSTB and interrupt return signal INTB are directly connected with STM32F103C8T6, using 10kΩ resistors for pull-up, to assist the system to work stably; and STM32F103C8T6 uses the same external 8 MHz clock; light-emitting diodes D1, D2 are used for power-on indication after reset; MBS (pin 12) is used as bias, connected with an RC circuit to ensure that a floating voltage can be output to. LD3320 speech recognition chip is a chip that integrates speech recognition function, which is released by ICRoute company. The chip integrates optimized algorithms inside, which can realize fast and stable speech recognition. The characteristics of LD3320 include no need to externally connect flash and RAM, and no need for users to perform voice training and recording in advance, which can complete the speech recognition task of non-specific people. The recognition accuracy is high, which makes LD3320 have high practical value in speech recognition applications. STM32F103C8T6 main controller selects STM32F103C8T6 chip of ST company, which is a microcontroller based on ARM Cortex-M3 32-bit RISC kernel. The working frequency of STM32F103C8T6 can be up to 72 MHz, and it is built-in with high-speed memory, including 64 KB flash and 20 KB SRAM, which provides enough resources for system storage requirements. Communication interface LD3320 adopts a parallel mode to directly interface with STM32F103C8T6, which makes the data transmission fast and efficient. Both use 1kΩ resistors for pull-up to ensure signal stability. When determining the data segment and the address segment, A0 pin is used to determine whether it is a data segment or an address segment. Through the level state of A0 pin, STM32F103C8T6 can distinguish whether it is sending data or receiving data. Control signals, reset signals and interrupt return signal INTB are directly connected with STM32F103C8T6. These signals also use 10kΩ resistors for pull-up to ensure signal stability and assist the system to work stably. LD3320 and STM32F103C8T6 use the same external 8 MHz clock, which ensures the clock synchronization between the two, avoiding communication problems caused by clock desynchronization. Light-emitting diodes D1 and D2 are used for power-on indication after reset. When the system is powered on and works normally, these two LEDs will light up, indicating that the system is running normally. MBS (pin 12) is used as bias, connected with an RC circuit to ensure that a floating voltage can be output to (possibly a circuit part not described in detail).

[0102] The voice recognition system realizes the capture and recognition of voice through the LD3320 chip, and the STM32F103C8T6 as a main controller is responsible for processing the data sent by the LD3320 and controlling the operation of the whole system.
