The voice interactor 11 can have a built-in instruction self-learning algorithm for the SNR9816 voice chip and the STM32 microcontroller. After the collected human voice is processed by noise reduction filtering, it is converted into a digital signal and compared with the preset garbage name-garbage category comparison relationship, thereby Establish the corresponding relationship between garbage names and garbage categories to achieve garbage classification. The human body sensor 12 may be a pyroelectric sensor. It should be understood that the above implementation is only an example and is not a limitation of the present invention.

Further, in this embodiment, as shown in Figures 3 and 8, the garbage classification collection bucket 13 includes an outer bucket 131, an inner bucket 132 arranged inside the outer bucket, and an automatic lid opening mechanism that controls the opening and closing of the lid on the top of the outer bucket. 133.

The top is hinged with the bucket lid, the pressure sensor is set at the bottom of the inner bucket, the garbage position identifier 134 and the automatic compression mechanism 135 are set on the inner bucket.

The controller 10 is electrically connected to the voice interactor 11, the automatic lid opening mechanism 133, the pressure sensor, the garbage location identifier 134, and the automatic compression mechanism 135, thereby realizing the control of the voice interactor 11, the automatic lid opening mechanism 133, the pressure sensor, and the garbage.

The controller 10 of the collection station sends the data to the back-end server. The monitoring personnel access the database in the server through the PC to obtain the garbage capacity and working status of each collection station. , data such as whether it is overflowing or not, provides data support for integrated management of smart sanitation. The controller 1 is connected to the host computer via Ethernet wired connection (OPC protocol). The host computer is installed at the main collection station and serves as a human-machine interface to display the internal status (including the garbage capacity, remaining space, compression stroke, and ultraviolet light). status, etc.) to the user.

Furthermore, a garbage door can be provided on the outer bucket 131, and the inner bucket 132 is movably connected to the outer bucket 131. The inner bucket can be taken out from the garbage door to facilitate the removal of garbage.

The working process of the speech recognition-based garbage classification system provided in this embodiment is:

The human body sensor detects whether a pedestrian is passing by in real time, and when it detects a pedestrian passing by, it sends a signal to the voice interactor to wake up the voice interactor. The voice interactor emits a "Welcome" tone, broadcasts the user guide, and communicates with the user via voice Interact, guide the user to say the name of the garbage to be thrown, and after collecting the name of the garbage to be thrown, send the name information of the garbage to be thrown to the controller, and the controller determines the garbage category based on the correspondence between the preset garbage name and the garbage category. And generate corresponding control instructions to control the automatic lid opening mechanism of the corresponding garbage classification collection bucket to open the lid, so that the user can throw the garbage to be thrown into the corresponding garbage classification collection bucket. Furthermore, the lid opening time can be preset (such as a 10-second countdown). When the preset lid opening time is reached, the controller controls the automatic lid opening mechanism to close the lid. Furthermore, the voice interactor can also feedback the corresponding garbage category and the operating status of the garbage classification collection bucket ("Compressing, please wait" or "Sorry, this bucket is full") to the user through voice."

The garbage position identifier in each garbage classification collection bucket detects the position of the garbage stored in the inner bucket in real time. When the garbage position exceeds the preset position, the garbage position identifier will send an overflow signal to the controller, and the controller will control the corresponding garbage classification. The automatic compression mechanism in the collection bucket compresses the garbage.

Specifically, in this embodiment, the garbage position identifier can be an infrared tube sensor, which is arranged at a preset position inside the inner barrel. The infrared tube sensor includes an infrared transmitting tube and an infrared receiving tube, which are respectively arranged on the inside of the inner barrel. On the two opposite inner walls, when the garbage contained in the inner bucket exceeds the preset position (that is, the garbage capacity in the garbage sorting and collection bucket reaches the maximum limit), the infrared ray emitted by the infrared emission tube will be blocked, thus infrared tube sensor Send an overflow signal to the controller to trigger the corresponding automatic compression mechanism for compression.

Furthermore, when the controller receives the overflow signal, in addition to controlling the automatic compression mechanism to compress the garbage, it can also send the overflow signal to the host computer for display, and can also control the voice interactor to issue "Compressing, please "Later" and other sounds to prompt the user.

Furthermore, if the remaining space after automatic compression reaches the set threshold, the overflow lock is triggered and the overflow signal is sent to the regulatory authority. Data can also be uploaded to the cloud platform to provide data support for integrated smart environmental sanitation management. The setting threshold is set by the staff according to actual needs, and the present invention does not limit this.

In addition, since the controller in each group of garbage classification collection stations is also connected to the host computer and server, the controller can upload the operation status of each group of garbage classification collection stations to the server, and the server will store the received operation status. , staff can access relevant data through PCs, so that relevant staff can promptly grasp the operation status of each group of garbage classification collection stations, and promptly respond according to the operation conditions (for example, the garbage in the garbage classification collection bin exceeds the preset position, and After being compressed by the automatic compression mechanism and still exceeding the preset position, the corresponding situation can be displayed on the display screen of the host computer, and the staff can promptly transport the garbage in the barrel away after seeing it to avoid excessive overflow of garbage). At the same time, the controller can also send the operation status of the garbage classification collection station to the host computer, which will be displayed to the user. Specifically, in this embodiment, the server can communicate wirelessly with the controller through a WIFI wireless connection, and the host computer can be connected to the controller through a wired Ethernet (OPC protocol). More specifically, the operation status can also include the garbage capacity, remaining space, compression stroke of the automatic compression mechanism, lid closing countdown, warning prompt, overflow indication, voltage display, etc. of each garbage classification collection bin in each group of garbage classification collection stations. , (More specifically, weight sensors, for example, can be set in each garbage classification collection bucket to monitor garbage weight and capacity sensors to detect garbage capacity. Afterwards, the controller calculates the remaining space percentage of the garbage classification collection bucket and feeds it back to the host computer for display. ). The above operating conditions are only examples, and may also include other operating conditions. For example, when an ultraviolet disinfection lamp is installed in the garbage classification collection bin, the operating conditions also include the status of the ultraviolet disinfection lamp, etc.

The garbage classification and collection system based on speech recognition provided in this embodiment guides the user to classify garbage through voice interaction, uses the voice interactor to collect the garbage names spoken by the user, determines the category according to the garbage name, and triggers the corresponding garbage classification. The collection bucket automatically opens its lid and provides voice feedback to the user based on the operating status, making garbage classification simple and effective and solving the problem of garbage classification from the source. At the same time, the garbage classification and collection system includes at least one group of garbage classification and collection stations and a server used to collect the operation status of each group of garbage classification and collection stations. Staff can access the database of the server through a PC to conduct unified management of each group of garbage classification and collection stations. ,More convenient. The system is equipped with a human body sensor, which will wake up the voice interactor only when a pedestrian is detected to reduce energy consumption. The system is also equipped with an automatic compression mechanism. When it is detected that the garbage capacity exceeds the preset capacity (the garbage position reaches the preset position), the controller controls the automatic compression mechanism to compress the garbage to prevent garbage from overflowing and sewage flowing across the way.
