Abstract:
PURPOSE: A method for transmitting and receiving data between a digital motor control unit and a centralized monitor control center using hybrid communication and an operating method thereof are provided to efficiently construct a system which collects and controls data transmitted to the digital motor control unit and easily control a user environment set. CONSTITUTION: A digital motor control unit(100) is comprised of a current detection block(101), a user interface block(102), a comparison operation process block(103), an output control block(104), and a wireless communication block(105). The current detection block detects a leakage current and a measurement current. The user interface block displays the detection result, set a motor protection and a use environment. The comparison operation process block operates various data and performs a comparison process algorithm. The output control block outputs the comparison operation result to an output terminal. The wireless communication block transmits and receives data to and from a wire/wireless relay server(200). The wire/wireless relay server includes a wire communication block(202), a wireless communication block(203), and a data analysis process block(201). A centralized monitor control center(300) includes a wireless communication block(301), a transmission and reception data analysis block(303), and a central server PC(302).
