Description

technical field [0001] The invention relates to the field of laser-powered communication, in particular to a laser-powered communication device, a communication method, and a power supply method. Background technique [0002] In the context of the rapid construction and development of the Global Energy Internet, the demand for real-time perception of the operating status of the power grid continues to deepen. The development of power system automation and smart grid has made the application of intelligent electronic devices and monitoring sensors in power transmission and transformation equipment more and more extensive. In order to accurately monitor various physical quantities of electrical equipment, a large number of sensor nodes of various types will be densely distributed in the area to be measured. [0003] Using laser transmission in optical fiber to transmit electric energy to remote nodes is an effective way to supply power to high-potential monitoring nodes. It c...

Problems solved by technology

[0004] However, the existing laser energy supply equipment is equipped with a VCSEL laser and a photoelectric detection module between the high-potential node and the low-potential node to realize two-way data communication, but the use of the laser leads to high power consumption of the high-potential node itself, reducing the The power that can be output to peripheral devices affects the energy supply effect

At the same time, the existing laser energy supply equipment still has the problem of poor system reliability, and the power supply module often fails, which seriously affects the reliability and safety of energy supply
