It can store software code that includes it.

Hereinafter, various operation examples of the smart trash can 20 will be described. The following various operation examples may be included in the above-described operation of the processor 230 .

The smart trash bin 20 may receive an identification signal including an identification ID of one trash bin among a plurality of preset identification IDs from the user terminal 10 through the transceiver 220 . Here, each of the plurality of preset identification IDs may correspond to each of the plurality of trash cans as described above. In other words, in the present disclosure, the identification ID means an identifier assigned to each trash bin to identify a trash bin in which a specific type of garbage is accommodated.

The smart trash can 20 identifies one trash can selected by the user of the user terminal 10 based on the identification signal received from the user terminal 10 . To this end, a plurality of identification IDs for each of the plurality of trash cans may be allocated and stored in the memory 240 .

Thereafter, the smart trash can 20 may control one trash can corresponding to the received identification signal to output an identification voice. Here, the identification voice is set differently for each of the plurality of trash bins. Accordingly, the user can identify the location of the trash can by listening to the identification voice output from one trash can selected by the user.

For example, if the identification ID included in the identification signal is assigned to the plastic trash bin, the smart trash bin 20 may control the plastic trash bin among the plurality of trash bins to output an identification voice, in which case the identification voice is different It may be uniquely used only for the plastic waste bin in order to identify the waste bin and the plastic waste bin.

Thereafter, the smart trash can 20 may measure pressure sensing data when one trash can is opened from one trash can corresponding to the received identification signal. The pressure sensing data may be measured by a pressure sensor (not shown) when the user steps on the footrest 215 included in the trash can.

When the pressure sensing data is measured, the smart trash can 20 may control one trash can corresponding to the received identification signal to output an identification voice again. In other words, when the processor 230 included in the smart trash bin 20 receives the pressure sensing data measured from the pressure sensor (not shown), the processor 230 detects one trash bin corresponding to the received identification signal with an identification voice. can be controlled to output again.

Accordingly, the visually impaired can primarily receive an identification voice for identifying the location of the trash bin selected by them, and check whether the trash bin they have selected is correct when they step on the footrest 215 after approaching the trash bin. You can receive an identification voice for the second time again. Therefore, according to the separate collection system for the visually impaired of the present disclosure, the visually impaired can safely and conveniently identify the location of the trash can without touching the trash accommodated in the trash can.

Alternatively, the smart trash can 20 may sense the state of the amount of garbage in each of the plurality of trash cans, and transmit a warning signal according to the sensed amount of garbage to the user terminal 10 .

Specifically, the smart trash can 20 may measure distance sensing data through the ultrasonic sensor 214 and determine whether the measured distance sensing data is equal to or greater than a preset threshold. When it is determined that the distance sensing data is equal to or greater than a preset threshold, the smart trash can 20 may transmit a warning signal to the user terminal 10 . In other words, when the processor 230 included in the smart trash bin 20 receives the distance sensing data measured from the ultrasonic sensor 214 , the processor 230 sends a warning signal to the user terminal 10 through the transceiver 220 . can be sent to

For example, the warning signal may be a signal for notifying the user terminal 10 that there is a trash bin having a trash amount equal to or greater than a certain level in the inner space 212 among the plurality of trash bins. Accordingly, upon receiving the warning signal, the user terminal 10 may notify the user that there is a trash bin having a garbage amount equal to or greater than a certain level in various forms (eg, audio output, etc.).

Hereinafter, an interface that can be provided to a user by the user terminal 10 included in the separate collection system for the visually impaired will be described. The interface may be provided together when a separate application implemented for the separate collection system for the visually impaired is executed in the user terminal 10 .

In the user terminal 10, one of the first mode in which the first interface is provided and the second mode in which the second interface is provided is set according to an input from the user. Also, a first interface or a second interface corresponding to each mode may be provided according to whether one set mode is the first mode or the second mode.

In the present disclosure, the first mode may be a mode set for the visually impaired who can identify a little color among the visually impaired. In addition, the second mode may be a mode in which the visually impaired can operate the user terminal 10 without touching the user terminal 10 .

Referring to FIG. 4 , in the first mode, the user terminal 10 may provide the first interface 101 to the user through the screen 100 . The first interface 101 includes a first layout 102 and a second layout 103 .

In common, each of the first layout 102 and the second layout 103 may be displayed in different colors. Accordingly, the user can execute a desired function according to the color of the layout.

The first layout 102 is related to application driving or setting. For example, the first layout 102 may include a plurality of first sub-layouts 102a, 102b, 102c, and the plurality of first sub-layouts 102a, 102b, 102c may include an app usage method, Bluetooth settings and functions related to application driving or setting, such as voice setting.

Here, in particular, the voice setting layout is intended to provide a function for variously setting the above-described identification voice for each trash bin.

The second layout 103 is for trash can selection. For example, the second layout 103 may include a plurality of second sub-layouts 103a, 103b, 103c, and the plurality of second sub-layouts 103a, 103b, 103c correspond to each of the plurality of trash bins. can be

When the user selects (eg, touch, etc.) any one of the plurality of second sub-layouts 103a, 103b, 103c, the user terminal 10 generates an identification signal corresponding to the selected one layout to generate the smart trash bin 20 ) is sent to

For example, when the user selects 'plastic' from among the plurality of second sub-layouts 103a, 103b, 103c, the user terminal 10 generates an identification signal including the identification ID of the plastic trash bin to generate a smart trash bin ( 20) to the Thereafter, the smart trash bin 20 controls the plastic trash bin to output an identification voice so that the user can identify the location of the plastic trash bin.

Referring to FIG. 5 , in the second mode, the user terminal 10 may provide the second interface 104 to the user through the screen 100 . The second interface 104 may be a voice interface.

Specifically, the second interface 104 may be a voice interface for receiving a selection voice for selecting one trash can from the user. Accordingly, when the user speaks a selection voice for selecting a specific trash can in the second mode, the selection voice is input to the user terminal 10 through the second interface 104, and the user terminal 10 responds to the selection voice. An identification signal may be transmitted to the smart trash bin 20 .

For example, when the user says 'plastic' by voice, the user terminal 10 recognizes the selected voice through the second interface 104, and generates an identification signal including the identification ID of the plastic trash bin to create a smart It is transferred to the trash can (20). Thereafter, the smart trash bin 20 controls the plastic trash bin to output an identification voice so that the user can identify the location of the plastic trash bin.

According to the first interface 101 and the second interface 104 described above, the visually impaired can easily and conveniently operate the user terminal 10 for each type of visually impaired.

In S130, the smart trash bin 20 controls one trash bin corresponding to the identification signal among the plurality of trash bins to output an identification voice. The identification voice is set differently for each of the plurality of trash bins.

In S140 , the smart trash bin 20 controls one trash bin to output an identification voice again, based on measuring pressure sensing data generated when one trash bin is opened from one trash bin.

In S150, the smart trash can 20 measures distance sensing data.

In S160, the smart trash can 20 determines whether the measured distance sensing data is equal to or greater than a preset threshold.

If it is determined that the distance sensing data measured according to S160 is equal to or greater than the preset threshold value, the smart trash can 20 transmits a warning signal to the user terminal 10 in S170 .

As described above, S150 to S170 are shown to be performed after S140 in FIG. 6 as described above. However, S150 to S170 may be performed before S110, and may be performed simultaneously with or at the same time as S110 to S140.

According to the above-described separation and collection method for the visually impaired, an identification voice for identifying the location of the trash can selected by the person can be primarily guided, and when the step 215 is stepped on after approaching the trash can, the trash can selected by the user An identification voice to check whether it is correct may be secondarily guided again. Accordingly, the visually impaired can safely and conveniently identify the location of the trash can without touching the trash accommodated in the trash can.
