[0034] The operation of the pet dog waste collection system according to one embodiment of the present invention, based on the above-described configuration, is as follows.

[0035] First, the user connects to the server (40) using the user terminal (50), and then logs into the defecation collection application program to sign up for membership, thereby receiving the user's own personal identification QR code.

[0036] After the user is assigned their own personal identification QR code, when the pet dog defecates while walking the pet dog, the user logs into the feces collection application program to check the installation location of the nearby feces collection device (10).

[0037] The user can move to a waste collection device (10) near the walking path and check whether there are waste bags loaded in the waste bag storage container (12) through the waste bag checking window (121), and can take out and use waste bags through the waste bag discharge port (122).

[0038] If the waste collection device (10) is far from the walking path, use a waste bag that you are carrying to collect the dog's waste in the waste bag.

[0039] After collecting the dog's feces using a poop bag, when the user scans the personal identification QR code assigned to the poop collection application program with the QR code reader (21) of the poop collection device (10), the controller (23) of the control unit (20) transmits the user's personal identification QR code information to the server (40) via the communication unit (27) and the network (30), and the server (40) confirms whether the user is a member of the poop collection application program using the personal identification QR code information, and then transmits an authentication code to the controller (23) of the control unit (20).

[0040] The controller (23) of the control unit (20), having received an authentication code from the server (40), controls the door drive unit (24) to open the envelope insertion door (13).

[0041] When the bag insertion door (13) of the waste collection device (10) is opened in this way, the user inserts a waste bag containing the dog's waste into the bag insertion door (13).

[0042] When a waste bag is inserted into the bag insertion door (13), the sensor unit (22) of the control unit (20) detects this and transmits it to the controller (23), and the controller (23) then transmits this to the server (40) through the communication unit (27) and the network (30).

[0043] The server (40) accumulates reward points for each user, and then, when the user's reward points accumulate to a certain amount or more in the future, rewards the user by allowing them to use the accumulated reward points through a waste collection application program, thereby encouraging the user to actively perform waste disposal for the dog that occurs on the walking path.

[0044] Meanwhile, the waste bag inserted into the bag insertion door (13) of the waste disposal unit (10) falls into the body (141) of the elastic spray drop unit (14). As the waste bag collides with the elastic spray plates (142) installed alternately on the left and right inner sides of the body (141), the elastic spray plates (142) are bent by the elastic force, and accordingly, the falling speed of the waste bag is delayed.

[0045] At the same time, when the controller (13) detects through the sensor unit (22) that a waste bag has been inserted into the bag insertion door (13), it operates the conveyor drive unit (26) and simultaneously controls the spray drive unit (25) so that the disinfectant is sprayed through the elastic spray plate (142) and the elastic spray nozzle (143), thereby sterilizing and disinfecting the falling waste bag.

[0046] The sterilized waste bag is dropped onto the slide inclined surface (144) formed on the lower surface of the body (141), then slides down the slide inclined surface (144) by its own weight and is discharged out of the body (141) through the discharge port (141a), thereby being transported onto the conveyor belt (154) of the conveyor unit (15).

[0047] The controller (23) of the control unit (23) controls the conveyor drive unit (26) so that the conveyor belt (154) rotates counterclockwise by the front transfer roller (152) and the rear transfer roller (153), thereby transferring the feces bag to the storage space (not shown).

[0048] The feces bag transported to the front of the conveyor frame (151) by the conveyor belt (154) is placed on the seating plate (158) installed at the front of the frame (151), and the feces bag seating sensor (159) installed on the seating plate (157) detects this.

[0049] When the controller (13) detects that a waste bag has been placed on the placement plate (158) through the waste bag placement sensor (159) of the sensor unit (22), it drives the rotary motor (157) to rotate the placement plate (158) 90 degrees counterclockwise together with the rotation axis (156), thereby allowing the waste bag to be safely dropped into the storage space without bursting due to the impact of the fall.
