Optical fiber energy supply system based on multi-junction concentrating photovoltaic battery and energy supply method

Abstract

The invention relates to the technical field of optical fiber energy supply, in particular to an optical fiber energy supply system based on a multi-junction concentrating photovoltaic battery and an energy supply method. The optical fiber energy supply system based on the multi-junction concentrating photovoltaic battery is characterized by comprising four parts such as a laser module, an optical fiber coupling module, a light splitting module, photovoltaic conversion modules; the laser module uses a multiband laser module, laser beams output by the multiband laser module are incident to an energy transmission optical fiber after being merged through the optical fiber coupling module and then are incident to the light splitting module after a certain distance of transmission, the light splitting module is used for splitting a laser beam into multiple laser beams, and the split laser beams supply power for load circuits and sensing equipment through the corresponding photovoltaic conversion modules.

Description

technical field [0001] The invention relates to the technical field of optical fiber energy supply, in particular to an optical fiber energy supply system based on multi-junction concentrating photovoltaic cells and an energy supply method thereof. Background technique [0002] The Internet of Things can realize remote network digital transmission and storage systems, remote network data communication and storage, and remote multi-network integration, and has become one of the strategic commanding heights of the current world economic and technological development. The construction of the Internet of Things is inseparable from the sensor network, including the collection and transmission of information; in fact, the sensor device is equivalent to each information collection point in the entire network, and the sensor arrangement in a wider range of fields and environments can realize "ubiquitous perception" is the ultimate goal. [0003] However, in some special environment...
