The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
As shown in fig. 1, an embodiment of the present invention provides a garbage classification apparatus based on a drone vehicle, which includes a drone vehicle 100 and a classification apparatus 200. Specifically, the sorting device 200 is installed on the unmanned vehicle 100 and fixed by a fixing groove (not shown).
In the embodiment of the present invention, the classification apparatus 200 includes: lid 1, detection storehouse 2, locker 3 and control module A.
As shown in fig. 2, in the embodiment of the present invention, the cover 1 is provided with a first through hole 11 and an installation area 12, the first through hole 11 is used for placing garbage, and the installation area 12 has an interactive module (not shown). Optionally, the interaction module is connected with the control module and the background server, and comprises a plurality of indicator lights, an operable screen and a voice module, wherein the interaction module comprises three indicator lights as an example, and respectively represents three states of ready, running and abnormal; the operable screen is used for information prompt, two-dimensional code display and simple operation; the voice module is used for playing voice and prompting a user to know operation steps and garbage classification results conveniently.
In the embodiment of the present invention, the control module is housed in the cover body 1, and it needs to perform tasks of three aspects of control, communication and operation, and has a power supply, a processing chip, an ADC analog-to-digital conversion channel, a timer, a basic level input/output, a serial communication, a PWM, an auxiliary module, and the like. The auxiliary module comprises a mobile network module, SDRAM data records, a TFTLCD display screen, an electric frequency conversion circuit, an isolation and protection circuit and the like. It should be noted that the control module receives signals of various sensors, processes data received by the sensors through a preset algorithm, and controls the motors to complete the garbage classification process.
Optionally, the processing chip must have functions of a multi-channel ADC analog-to-digital conversion module, GPIO basic input and output, UART serial interface communication, second and millisecond timers, external interruption, PWM pulse width modulation, and the like, and can adapt to outdoor temperature and humidity conditions, operate stably for a long time, and have low power consumption, so that the model of STM32F407 is selected. In the embodiment of the invention, the GPIO is mainly used for outputting and controlling various switches in equipment, such as a relay, an indicator light, a buzzer and the like, and the display content of the LCD screen can be controlled by matching a plurality of IO outputs. In order to improve the sensitivity and the real-time performance, the input switching signal is mainly interrupted by external processing, for example, when the time of the triggering signal of the switching sensor is recorded, the recording is required to be more accurate (the identification accuracy is influenced).
The core processor is driven to run by mainly generating pulse frequency signals which can be accepted by the stepping motor through PWM. The higher the frequency of the input, the faster the motor moves. Currently the speed of each motor is constant, i.e. the pulse frequency output by the core processor is constant. The UART serial port communication is used for carrying out control operation with other expansion modules, such as wifi and voice modules. In addition, the TF card is read and written by using the SPI interface, and a simple FAT32 file system needs to be established at the same time, so that data needing to be stored in a power-off mode is backed up in a file form. Except for the switch type sensor, the pressure sensor and the ultrasonic wave are all output as analog signals. STM32 multichannel ADC analog-to-digital conversion can monitor the analog signals of a plurality of sensors simultaneously, and combines ADC interruption and DMA, can more accurately save denser discrete data record.

Timers, including a millisecond timer and a second timer, each start interrupt accumulation at system start-up, and other programs may obtain count values as needed.
As shown in fig. 2 and 3, in the embodiment of the present invention, the detecting chamber 2 is accommodated in the cover body 1, and includes an installation plate 21, an accommodating body 22, a tray 23, a sensor module, and a motor module.
As shown in fig. 2 and 3, optionally, both the sensor module and the motor module are connected with the control module, the sensor module including an inductive proximity switch sensor 41, a capacitive proximity switch sensor 42, a diffuse reflective photoelectric switch sensor 43, an ultrasonic sensor 44, a pressure sensor (not shown) and a position sensor (not shown). Wherein the pressure sensor is located in the tray 23.
As shown in fig. 2 and 3, the mounting plate 21 may be provided with a second through hole (not shown), a moving rail 211, and a sensor rail 212. Wherein, the tray 23 is movably disposed on the moving track 211, and the sensor module is movably disposed on the sensor track 212. It should be noted that the sensor module is movably disposed on the sensor track 212, which means that at least one sensor in the sensor module is movably disposed on the sensor track 212, in the embodiment of the present invention, the inductive proximity switch sensor 41, the capacitive proximity switch sensor 42, and the diffuse reflection photoelectric switch sensor 43 are movably disposed on the sensor track 212, the ultrasonic sensor 44 is disposed on the mounting plate 21 on one side of the accommodating body 22, and the position sensor is disposed on one side of the accommodating body 22. Optionally, the longest distance of the sensor track 212 is 25 cm.
As shown in fig. 2 and fig. 3, optionally, the accommodating body 22 includes an accommodating space 221 penetrating up and down and a plurality of hollow structures 222. The first through hole 11 is communicated with the accommodating space 221, the second through hole is located below the accommodating space 221, and the sensor module is used for detecting garbage in the accommodating space 221. The hollow structure 222 is connected to the accommodating space 221 and is disposed corresponding to the sensor module. It should be noted that, the hollow-out structures 222 and the sensor modules are arranged correspondingly, that is, at least one sensor in the sensor modules faces the hollow-out structures 222, so that the sensor can acquire data of the garbage in the accommodating space 221 through the hollow-out structures 222, in the embodiment of the present invention, the inductive proximity switch sensor 41, the capacitive proximity switch sensor 42, the diffuse reflection photoelectric switch sensor 43, and the ultrasonic sensor 44 correspond to one hollow-out structure 222, respectively, so that each sensor acts on the garbage at a proper angle. In the embodiment of the present invention, by providing multiple types of sensors, information such as a position, a weight, and a material property of the garbage can be detected, so that the control module can perform recognition processing to classify the garbage.
It should be noted that the inductive proximity switch sensor 41 is very sensitive to metal (including aluminum), and when the recycled product is a pop can or other metal material, the sensor is activated very quickly, i.e., the activation distance is large. The capacitive proximity switch sensor 42 is effective for all materials including metal, glass, plastic, wood, and the sensor excitation distance may vary depending on the material. The diffuse reflection photoelectric switch sensor 43 is inferior to metal, mirror surface, and paper in effect to transparent articles such as white plastic and transparent glass, and therefore can be one of the main bases for identifying the material of garbage. Any material of the ultrasonic sensor 44 can absorb sound, but the degree of absorption is very different, so according to the characteristic, the sound absorption performance of the recycled product is monitored by matching the ultrasonic transmitter and the receiver. The pressure sensor can acquire the weight of the garbage, and the material range of the recycled product or whether the recycled product is filled with sundries or not can be roughly known according to the weight by matching with data parameters of other sensors.

It should be noted that, the initial position of the tray 23 is located on the moving track 211 and below the accommodating body 22, i.e. between the accommodating space 221 and the second through hole, the communication state is "closed", and after the tray 23 moves on the moving track 211 from the initial position, the communication state between the accommodating space 221 and the second through hole is "communicated", and at this time, the garbage in the accommodating space 221 can enter the storage cabinet 3 through the second through hole.
As shown in fig. 2 and 4, the storage cabinet 3 may alternatively include a guiding structure 31, a second motor 32 and a plurality of storage spaces 33, wherein the plurality of storage spaces 33 are respectively used for placing different types of garbage, and each storage space 33 may store one type of garbage, or each two storage spaces 33 may store one type of garbage, without limitation. For example, the types of the garbage respectively corresponding to the four storage spaces 33 are glass, plastic, metal, and others. The guiding structure 31 is located below the second through hole and connected with the second motor 32, the second motor 32 is connected with the control module, and the second motor 32 is used for controlling the rotating direction of the guiding structure 31 to guide the garbage to enter the storage space 33 of the type corresponding to the garbage. Specifically, after the control module analyzes the sensor data acquired by the sensor module to determine the type of the garbage, the control module controls the guiding structure 31 to guide the garbage to enter the storage space 33 of the type corresponding to the garbage. It will be appreciated that the guide structure 31 has a cushioning effect on the waste in addition to a guiding effect.
Optionally, a compressor, a shock absorber or a packaging device can be arranged below or at the side of the storage cabinet 3, for example, the pop can needs to be flattened during storage and is not too space-consuming; the shock absorber is used for preventing the glass bottle from being broken when falling; the packaging equipment is convenient for recovery personnel to collect in order to arrange the recovered materials.
Optionally, the unmanned vehicle comprises a sensing module, a core processing module and a communication module, wherein the sensing module is connected with the core processing module, and the communication module is connected with the core processing module, the server and the control module and used for receiving instructions and feedback information. Optionally, the communication module communicates with the classification device via a CAN bus.
Specifically, the sensing module comprises a front binocular camera and a rear binocular camera, a front laser radar, a rear laser radar, eight millimeter wave radars and a differential positioning module, wherein the front binocular camera and the rear binocular camera are used for imaging an obstacle in front of the unmanned trolley and identifying a marked scenery; the front and the back laser radars respectively obtain the far and near depths of the barrier, namely ranging; the periphery of the trolley is provided with eight millimeter wave radars which are used for detecting objects close to the periphery of the trolley body; and the differential GPS positioning module is used for acquiring the differential positioning module, so that the walking route can be conveniently planned. It should be noted that the relevant information, namely the environmental information, the environmental information and the positioning information obtained by the front and rear two binocular cameras, the front and rear two laser radars and the eight millimeter wave radars are transmitted to the core processing module for processing,
the system comprises a core processing module, a vehicle-mounted control module and a vehicle-mounted control module, wherein the vehicle-mounted control module is used for controlling the electronic driving direction, braking and an accelerator; and the trolley control module is used for calculating the current running environment according to the instruction sent by the classification device and the environment information and the positioning information, planning a route and coordinating the trolley control module to control the unmanned trolley. Alternatively, the instruction issued by the recycling device may be an instruction input through the interaction module or an instruction issued when the sorting device receives garbage, or an instruction received by the sorting device from a server, or the like.
It should be noted that the unmanned vehicle provided by the embodiment of the invention has an L4-level automatic driving capability, and a map is built in a core processing module, so that functions of low-speed cruising, obstacle avoidance, situation perception and the like can be realized. The user can obtain the position state information of all the garbage classification devices through a mobile phone application program, a WeChat applet or an APP, and can also reserve a certain classification device loaded on an unmanned trolley to go to a certain place (target position) on a specified line for garbage recycling service.
As shown in fig. 5, an embodiment of the present invention further provides a classification method applied to the above garbage classification apparatus, including steps S100 to S600:
s100, the unmanned trolley moves to a target position.
Optionally step 2100 comprises step S101 or step S102:
s101, when the unmanned trolley is in a moving state and when the classification device receives garbage or an object approaches the unmanned trolley, determining the position of the current unmanned trolley as a target position.
Specifically, the unmanned vehicle has two service modes, namely a fixed service mode and a mobile service mode, and the service modes can be controlled by a server or a classification device. When the unmanned trolley is in a mobile service mode, the server sends a 'tracing instruction' through a preset route to control the unmanned trolley to move according to the preset route to execute a tracing task, and when the unmanned trolley is in the moving state, the classifying device receives garbage input from a user, the current position of the unmanned trolley is determined as a target position, the unmanned trolley moves to the target position and stays in the 'service state', and the unmanned trolley exits the 'service state' until garbage classification is completed. And when the unmanned trolley is in a fixed service mode, the unmanned trolley stops at a fixed position to wait for a user to throw garbage. Alternatively, when the unmanned vehicle is in a moving state and an object (e.g., a person) approaches the unmanned vehicle (e.g., the distance from the unmanned vehicle is less than an approach threshold), the unmanned vehicle may take the current position as the target position and then enter a "pause state" to notify the classification device of the information, and the classification device starts timing. If the sorting device does not enter the waste recycling workflow (namely, the garbage is not received) within the timing threshold (for example, 30 seconds), a 'tracing instruction' or a 'position instruction' is sent to the unmanned trolley, namely, the unmanned trolley enters the flow service mode or the target task mode, the unmanned trolley is enabled to avoid obstacles and leave, and if the waste recycling workflow (namely, the garbage is received) is triggered within the timing threshold (for example, 30 seconds), the sorting device sends a 'service state' instruction, and the trolley enters the 'service state'.
And S102, determining a target position by receiving a user instruction so that the unmanned trolley moves to the target position.
Specifically, the user instruction can be applied to the server by the user through modes such as APP, public numbers and the like, the server generates the user instruction and sends the user instruction to the classification device and the unmanned trolley, and therefore the target task mode is entered. For example, when a user applies through an APP, a server sends a user instruction including a user position (i.e., a target position) to a classification device and an unmanned vehicle according to the application and the position (i.e., the target position) of the user, a core processing module of the unmanned vehicle generates a planned route and controls the unmanned vehicle to move to the target position according to the planned route, the unmanned vehicle stays at the target position for a preset stay time (e.g., 30 seconds), the user is waited to throw garbage into the unmanned vehicle, if the unmanned vehicle operates within the preset stay time, the unmanned vehicle automatically enters a fixed service mode or a mobile service mode, and if the user instruction includes a plurality of target positions, the core processing module is responsible for completing optimal path selection and preferentially reaches one of the target positions.
Optionally, the server or the classification device queries the state of the unmanned vehicle at regular time, and the control module of the classification device sends query information to the classification device through the CAN bus every 2 seconds to know various information on the classification device, including: an operation state, a position (corrected GPS information), a power supply state, a vehicle body abnormality, and the like, and the operation is continued without being interfered by other operations. Optionally, when the garbage classification device is in an abnormal maintenance state, for example, when the classification device or the unmanned vehicle has a fault, including but not limited to abnormal information such as too low battery voltage, the server may stop the service itself, the server may send a "return command" to the unmanned vehicle, and the unmanned vehicle may return to the maintenance point according to a preset fixed path.
S200, acquiring sensor data of the current garbage through a sensor module.
In an embodiment of the invention, the sensor data comprises detection data of the ultrasonic sensor and a distance set, wherein the distance set comprises a first trigger distance of the inductive proximity switch sensor, a second trigger distance of the capacitive proximity switch sensor and a third trigger distance of the diffuse reflectance optoelectronic switch sensor.
In order to identify the recycled product in a non-visual manner, it is necessary to consider the characteristics of the material, and the material may have different properties, such as sound wave absorption, light reflection, dielectric constant, conductivity, and weight. The single attribute information of the detection objects with different materials may be similar, but the difference can be highlighted by fusing a plurality of information. Therefore, based on the multi-information difference, different types of sensors are combined, and the garbage classification result can be obtained through the analysis of the difference of the trigger distances of the different types of sensors.
Optionally, step S200 includes the steps of: S110-S120:
and S110, controlling the sensor module to move on the sensor track at a preset speed, and recording the movement starting time and the trigger time of each sensor.
Optionally, the sensor module is arranged at an initial position, so that the inductive proximity switch sensor, the capacitive proximity switch sensor and the diffuse reflection photoelectric switch sensor of the sensor module cannot detect the garbage in the accommodating space at the initial position, and the sensor module is controlled to move, specifically, the inductive proximity switch sensor, the capacitive proximity switch sensor and the diffuse reflection photoelectric switch sensor are controlled to move at a preset speed on the sensor track, the triggering time of different sensors is different due to the difference of garbage types in the moving process, and the triggering time of each sensor is recorded at the moment. It should be noted that, when the sensor module starts to move, the time at this time, i.e., the movement start time, is recorded. In addition, the preset speed can be set according to actual needs and is not limited.
And S120, determining a distance set according to the preset speed, the movement starting time and the trigger time.
Specifically, the formula for calculating the trigger distance is as follows: the triggering distance is [ total length of the sensor track- (triggering time-movement starting time) × preset speed ], and the first triggering distance of the inductive proximity switch sensor, the second triggering distance of the capacitive proximity switch sensor and the third triggering distance of the diffuse reflection photoelectric switch sensor can be obtained through calculation according to the triggering time of the inductive proximity switch sensor, the capacitive proximity switch sensor and the diffuse reflection photoelectric switch sensor. It should be noted that the detection data of the ultrasonic sensor can be obtained by detecting the garbage with the ultrasonic sensor. In some embodiments, the trigger distance may also be (trigger time-movement start time) a preset speed, and is not particularly limited.
S300, determining weights corresponding to the detection data, the first trigger distance, the second trigger distance and the third trigger distance respectively according to a preset database.
