WIRELESS ENERGY AND DATA TRANSMISSION SYSTEM USING LASER FOR MOVING OBJECT

摘要

The present invention relates to a system for wirelessly transmitting energy and data using laser for a moving object. The present invention provides a system for wirelessly transmitting energy and data using laser for a moving object comprises: a main tracking module which is rotatably provided on a frame to track a moving object toward the moving object; a main laser module which is mounted in the main tracking module to transmit a first optical signal for power conversion and a second optical signal corresponding to data to be transmitted; a power generation unit which generates driving power for the main laser module; a main laser driving unit which drives the main laser module using power generated by the power generation unit; a main optical detection unit which is mounted in the main tracking module to receive a third optical signal transmitted from the moving object; a main demodulation unit which demodulates a signal outputted from the main optical detection unit; a main modulation unit which modulates data to be transmitted to the moving object and provides the main laser driving unit with the modulated data such that the second optical signal can be generated; and a main processing unit which processes the signal received from the main demodulation unit, outputs, to the main modulation unit, the data to be transmitted to the moving object, and controls the driving of the main tracking module, wherein the moving object processes reception of the second optical signal transmitted from the main laser module, transmits the third optical signal, and converts the first optical signal into an electrical signal to charge a built-in battery. The system for wirelessly transmitting energy and data using laser for a moving object can provide a moving object with optical energy for power conversion and communication information using laser.
