Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0013] The optical fiber energy and data parallel transmission method involved in the present invention is characterized in that the laser energy and data transmission are completed through the same optical cable. The method of energy transmission is: the high-energy laser emitted by the power laser 1 at the host end is coupled to the energy fiber 4 through the fiber interface 3, the energy fiber 4 transmits the light energy to the slave end, and the divergence lens 5 at the slave end outputs the light energy from the fiber interface 3 The high-energy laser spot diverges into parallel light and irradiates the photovoltaic cell 6 to generate electric energy, which is stored in the battery 7 for use by low-power consumption appliances, thereby completing energy transmission. The method of data transmi...

Abstract

The invention provides a method and a device for parallel transmission of optical fiber energy and optical fiber data. High-energy lasers transmitted by a power optical maser at a host machine end and lasers transmitted by an optical fiber data transceiver and subjected to data modulation are coupled to energy optical fibers through an optical fiber interface, optical energy and data are transmitted to a slave machine end by the energy optical fibers, high-energy laser spots output by the optical fiber interface are diffused to be parallel light by a diverging lens at the slave machine end, the parallel light irradiates on a photocell to generate electric energy, generated electric energy is stored in a storage battery to be used by a low power consumption electrical appliance, meanwhile the data transceiver receives laser modulation signals transmitted by the energy optical fibers, and thus the parallel transmission of the energy and the data is completed. The method and the device for the parallel transmission of the optical fiber energy and the optical fiber data has the advantages of being good in anti-interference performance, small in size and strong in explosion-proof performance, and can be widely applied to the oil and gas field environment or the industry environment which are low in energy consumption, small in data transmission quantity and high in explosion-proof requirement.

Description

technical field [0001] The invention relates to a method and device for parallel transmission of energy and data through the same optical cable, in particular to a method and device for parallel transmission of optical fiber energy and data, and belongs to the field of wired communication. Background technique [0002] In optical fiber transmission, due to the iterative effect formed between different optical fibers, the optical pulse tends to transmit data along the line rather than energy optical fiber lines. According to the principle of total reflection, light hardly overflows from the optical fiber, which makes the optical fiber have high safety performance and light weight. , Small size, small attenuation, wide frequency range, low loss, strong anti-interference, high capacity, good confidentiality and other advantages, has become one of the main wired communication methods today. Existing optical fiber transmission methods and devices can only complete single data or ...
