- A driving method for a modular electric cart comprising: a cart body on which a cargo box is installed; and a detachable cart control device detachably attached to the cart body, communicating with a management server, receiving work instruction information regarding items loaded in the cargo box from the management server and displaying it on a screen, and controlling the driving of the cart body. A step of receiving loading target item information including item identification information assigned to each loading target item from a management server; A step of collecting an image of a specific item loaded in a cargo compartment, and extracting item identification information corresponding to the specific item from the image of the item; If the above-mentioned extracted item identification information is not included in the above-mentioned received item information to be loaded, the step of transmitting loading item error information for the specific item to the management server; and A step of receiving work instruction information for the specific item from the management server, and outputting the work instruction information as voice or on a screen so that the worker loading the item can recognize it; Includes, A driving method for a modular electric cart, characterized in that the above-described detachable cart control device is separated from the cart body when work instruction information is not received from the management server during a time interval.
- In paragraph 4, The step of extracting the above-mentioned item identification information is, A wireless control device installed on the modular electric cart generates an image of a specific item loaded into the cargo compartment; and When the wireless control device transmits the image of the item to the electric module installed on the modular electric cart, the electric module extracts item information attached to a certain area of the specific item from the image of the item as item identification information; A driving method for a modular electric cart characterized by including
Description
Modular type electric cart and driving method thereof The present invention relates to a modular electric cart and a driving method thereof, and more specifically, to a modular electric cart and a driving method thereof that reduces the cost of purchasing an expensive electric cart by creating a modular electric cart by attaching an electric module in a modular manner to an existing manual cart, and not only allows the electric module to be controlled by a detachable wireless control device, but also enables the electric cart to be automatically controlled by simple movements of pushing or pulling the cart based on an intuitive user experience. Goods transport carts are primarily used in various settings, such as courier/cargo warehouses and factories, to move large quantities of goods or cargo. Manual carts, operated by workers using physical strength, are commonly used. However, when the size or weight of the goods or cargo makes it difficult to move them using manual carts, electric carts such as cargo trolleys, carts, and roll containers are utilized. However, existing electric carts have limitations that make them difficult to use widely due to their heavy weight and high price, as they utilize high-torque motors. Additionally, since the electric cart must be controlled using a designated wireless control device, it becomes impossible to control the cart if the device is lost. These conventional manual or electric carts are widely used by workers for picking operations in sites such as logistics centers. Picking refers to the process of selecting products from storage locations based on customer orders and placing them into picking boxes. Picking accounts for more than 80% of the total working time in a logistics center, and because picking errors in products delivered to the supplier can lead to claims from the supplier, accurate picking must be completed within a set time. The shipping operation is the final stage of the logistics center, following receiving, storage, and outbound (picking) operations. Once sorted by destination, products are returned to the shipping waiting area to await loading. At this stage, even if shipping and sorting are done properly, incorrect loading onto a vehicle can lead to misdelivery; therefore, large-scale errors at the pallet or roll container level must be prevented. However, since on-site workers manually load products, there is a problem in that it is difficult to determine in real time whether the loading operation has been properly carried out.
