1. A method for assisting proximity sensor-based product picking, which is performed by an apparatus for assisting product picking, the method comprising:
deriving a current picking target product from a picking product list;
selecting a first user terminal positioned in a first region where the current picking target product is displayed;
moving a cart including a plurality of picking boxes within a predetermined distance from the first user terminal;
stopping the movement of the cart when the cart is positioned within the predetermined distance from the first user terminal;
providing information on the current picking target product to the first user terminal; and
deriving a next picking target product from the picking product list when picking completion information is received from the first user terminal,
wherein a proximity sensor determines whether the cart is positioned within the predetermined distance from the first user terminal,
the proximity sensor includes a location-based service (LBS)-based proximity sensor,
the proximity sensor is positioned at a reference point corresponding to the first user terminal,
the moving of the cart within the predetermined distance from the first user terminal includes moving the cart to the reference point through a rail installed in advance,
a light emitting diode (LED) is positioned at the reference point,
the stopping of the movement of the cart includes:
stopping the movement of the cart when the cart is positioned within the predetermined distance from the reference point; and
visually indicating reaching of the cart to a first user corresponding to the first user terminal by emitting a light from the LED,
the method further comprises controlling a movement speed of the cart based on information on a distance between the cart and the first user terminal, information on whether the first user is positioned within a designated region of the first user, and grade information of a past processing speed of the first user,
the grade information of the past processing speed is derived based on an average of information on a past number of pickings per hour of the first user based on past processing history information,
the movement speed of the cart is determined based on Mathematical Formula:
 where v represents a movement speed of a cart, d represents information on a distance between a cart and a first user terminal, a represents a value according to information on whether a first user is positioned within a designated region, and b represents a value according to grade information of a past processing speed of a first user,
the a is derived as a value of 1 when the user is positioned within the designated region, and derived as a value of 0 when the user is not positioned within the designated region,
the b is derived as 0 when the average of the information on the past number of pickings per hour of the first user is less than a first threshold, the b is derived as 1 when the average of the information on the past number of pickings per hour of the first user is greater than or equal to the first threshold and less than a second threshold, and the b is derived as 2 when the average of the information on the past number of pickings per hour of the first user is greater than or equal to the second threshold,
the b is derived as 0 even when the average of the information on the past number of pickings per hour of the first user is greater than or equal to the first threshold when the past processing history information does not include information of past one month or more,
the b is derived as 1 even when the average of the information on the past number of pickings per hour of the first user is greater than or equal to the second threshold when the past processing history information does not include information of past three months or more, and
the movement speed of the cart is fixed to a preset maximum movement speed when the determined movement speed of the cart exceeds the preset maximum movement speed.
