In the following, embodiments of the present invention will be described clearly and in detail with reference to the accompanying drawings. The devices described in this specification may be entirely hardware or may have aspects that are partially hardware and partially software. For example, the agricultural machinery device (100) and each system, device, server, and each module or unit included therein that communicates with it may collectively refer to devices and related software for exchanging data of a specific format and content via electronic communication. In this specification, terms such as “unit,” “module,” “server,” “system,” “platform,” “device,” or “terminal” are intended to refer to a combination of hardware and software driven by said hardware. For example, the hardware here may be a data processing device including a CPU or other processor. Additionally, the software driven by the hardware may refer to a running process, object, executable file, thread of execution, program, etc. Additionally, in this specification, the units constituting the agricultural machinery device (100) are not intended to refer to physically distinct components. That is, although each unit of the agricultural machinery device (100) in FIG. 1 is depicted as a distinct block from one another, this is a functional distinction of the agricultural machinery device (100) based on the operation performed by it. Depending on the embodiment, some or all of the aforementioned servers may be integrated within a single device, or one or more servers may be implemented as separate devices physically distinct from other servers. For example, each unit of the agricultural machinery device (100) may be components connected to communicate with one another in a distributed computing environment.

Referring to FIG. 1, the agricultural machinery device (100) may include a communication unit (110), a driving unit (120), and a control unit (130). In some embodiments, the agricultural machinery device (100) may be a vehicle that can be used in agriculture and may be a device for moving agricultural work and farmland, etc. For example, the agricultural machinery device (100) may be a tractor, rice transplanter, combine harvester, etc. that can be used in agriculture, but may mean a means of transportation that is not limited to being used in agriculture, such as a passenger car or truck. The communication unit (110) can collect GPS (Global Positioning System) based location data. More specifically, the communication unit (110) can receive multiple location data including coordinates for each unit area by performing wireless communication with a GPS base station and a GPS satellite. Here, a unit area may be a divided zone within the farmland. For example, a unit area may be a rectangular area with a 2M interval, and the unit interval may be determined as a common multiple of the work interval of the farm machinery device (100A), but is not limited thereto. The communication unit (110) can receive locatio
