More specifically, in the present embodiment, the garbage classification collecting bin 13 may include a recyclable garbage classification collecting bin, a kitchen garbage classification collecting bin, a harmful garbage classification collecting bin, and other garbage classification collecting bins, which respectively correspond to the recyclable garbage, the kitchen garbage, the harmful garbage, and other garbage collection.
In this embodiment, the Controller 10 may utilize a single chip or a PLC (Programmable Logic Controller) to implement a control function. The voice interaction device 11 can be an instruction self-learning algorithm built in an SNR9816 voice chip and an STM32 singlechip, collected human voice is converted into a digital signal after being subjected to noise reduction and filtering, and the digital signal is compared with a preset garbage name-garbage category contrast relation, so that the corresponding relation between garbage names and garbage categories is established, and garbage classification is realized. The body sensor 12 may be a pyroelectric sensor, and it should be understood that the above implementation is only an example and not a limitation of the present invention.
Further, in the present embodiment, as shown in fig. 3 and 8, the garbage sorting and collecting bin 13 includes an outer bin 131, an inner bin 132 disposed inside the outer bin, an automatic lid opening mechanism 133 for controlling opening and closing of a bin cover on the top of the outer bin, a garbage position identifier 134 for identifying the amount of garbage stored in the inner bin, a pressure sensor for measuring the weight of the garbage and the degree of compaction, and an automatic compression mechanism 135 for compressing the garbage stored in the inner bin, wherein the automatic lid opening mechanism 133 is fixedly disposed on the top of the outer bin 131 and hinged to the bin cover, the pressure sensor is disposed at the bottom of the inner bin, and the garbage position identifier 134 and the automatic compression mechanism 135 are disposed on the inner bin.
The controller 10 is electrically connected to the voice interactor 11, the automatic uncovering mechanism 133, the pressure sensor, the garbage position identifier 134 and the automatic compressing mechanism 135 respectively, so as to control the voice interactor 11, the automatic uncovering mechanism 133, the pressure sensor, the garbage position identifier 134 and the automatic compressing mechanism 135.
The body sensor 12 is electrically connected to the voice interactor 11 so as to wake up the voice interactor when a person is detected to pass.
The controller 10 is in communication connection with the server 2 and the upper computer 14. Specifically, through WIFI wireless connection between controller 10 and the server, the controller 10 of collection station sends data to the rear end server, and monitoring personnel acquires data such as each collection station rubbish capacity, operating condition, whether overflow through the database in the PC access server, provides data support for wisdom sanitation integration management. The controller 1 is connected with an upper computer through an Ethernet wired connection (OPC protocol), and the upper computer is arranged in a main collection station and used as a human-computer interface to display internal states (including the garbage capacity, the residual space, the compression stroke, the ultraviolet lamp state and the like) for users.
Furthermore, a garbage door can be arranged on the outer barrel 131, the inner barrel 132 is movably connected with the outer barrel 131, and the inner barrel can be taken out from the garbage door, so that garbage can be taken out conveniently.
The working process of the garbage classification system based on the voice recognition provided in the embodiment is as follows:
the human body sensor detects whether pedestrians pass through in real time, and sends a signal to the voice interaction device when the pedestrians pass through is detected, the voice interaction device is awakened, the voice interaction device sends out prompting sound of 'welcome use', a use guide is broadcasted, voice interaction is carried out with a user, the user is guided to speak out the name of garbage to be thrown, after the name of the garbage to be thrown is collected, name information of the garbage to be thrown is sent to the controller, the controller determines the garbage category according to the corresponding relation between the preset garbage name and the garbage category, and generates a corresponding control instruction, and the automatic cover opening mechanism corresponding to the garbage classification collecting barrel is controlled to open a cover, so that the garbage to be thrown is thrown into the corresponding garbage classification collecting barrel by the user. Further, the uncovering time (such as counting down for 10 seconds) can be preset, and when the preset uncovering time is reached, the controller controls the automatic uncovering mechanism to close the barrel cover. Further, the voice interactor can also voice-feed back to the user the corresponding garbage category and the running status of the garbage classification collection bucket ("compress please later" or "apology this bucket is full").
The position of the rubbish that the interior bucket was deposited is detected in real time to the rubbish position recognizer in every waste classification collecting bin, and when the rubbish position exceeded and predetermine the position, rubbish position recognizer can send overflow signal to controller, and the automatic compressing mechanism in the waste classification collecting bin that corresponds is controlled by the controller compresses rubbish.
Specifically, in this embodiment, rubbish position identification ware can be infrared geminate transistor sensor, set up the inboard preset position department in interior bucket, infrared geminate transistor sensor includes an infrared emission pipe and an infrared ray receiver tube, set up respectively on two relative inside walls of interior bucket, rubbish that holds in the interior bucket surpasss preset position (also the rubbish capacity in the categorised collection bucket of rubbish reaches the biggest upper limit promptly), then can shelter from the infrared ray of infrared emission pipe transmission, thereby infrared geminate transistor sensor sends the overflow signal to the controller, trigger corresponding automatic compression mechanism and compress.
Furthermore, after the controller receives the overflow signal, the automatic compression mechanism is controlled to compress the garbage, the overflow signal can be sent to the upper computer to be displayed, and the voice interaction device can be controlled to send voices such as 'compressing, please later' and the like so as to prompt a user.
Furthermore, if the residual space after automatic compression reaches a set threshold, an overflow lock is triggered, and an overflow signal is sent to a supervision department. And the data can be uploaded to a cloud platform, so that data support is provided for intelligent environmental sanitation integrated management. The set threshold is set by the operator according to actual needs, and the invention is not limited to this.
