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.

In addition, because the controller in every group of rubbish classified collection station still with the host computer, the server communication is connected, therefore the controller can be with the operation condition of each group's rubbish classified collection station upload to the server, the server is saved the operation condition who receives, the staff can visit relevant data through the PC, so that relevant staff can in time master the operation condition of each group's rubbish classified collection station, in time handle according to the operation condition (for example, rubbish surpasss preset position in the rubbish classified collection bucket, and still surpass preset position after automatic compression mechanism compresses, then can show corresponding condition in the display screen of host computer, the staff sees the back can in time carry away rubbish in the bucket, in order to avoid rubbish too much to spill over). Meanwhile, the controller can also send the running condition of the garbage classification collecting station to the upper computer, and the running condition is displayed to a user by the upper computer.
