Abstract

Disclosed is an optical sensing and communication integrated active photoelectric transmission system. The optical sensing and communication integrated active photoelectric transmission system comprises a communication transmission system, a sensing data transmission system and power transmission cables, wherein the communication transmission system, the sensing data transmission system and the power transmission cables are integrated into a whole. The communication transmission system comprises a first photoelectric sending / receiving assembly TOSA / ROSA and a second photoelectric sending / receiving assembly TOSA / ROSA, wherein one end of the first photoelectric sending / receiving assembly TOSA / ROSA is connected with one end of the second photoelectric sending / receiving assembly TOSA / ROSA through the first cable. The sensing data transmission system comprises an optical grating temperature sensor, a fiber bragg grating vibration sensor, a broadband light source, an optical fiber coupler, an optical circulator, an edge filter, an analog photoelectric receiver, a low-power-consumption microprocessor and a solar cell, wherein light from the broadband light source is received by the optical fiber coupler through a port a of the optical fiber coupler and is partially transmitted to the solar cell through a port c of the optical fiber coupler, converted to electric energy and supplied to the low-power-consumption microprocessor.

Description

technical field [0001] The invention relates to a wireless communication base station and an information transmission system, in particular to an active photoelectric transmission system integrating optical sensing and communication, which can realize highly reliable energy supply and information transmission for a mobile communication antenna feeder system. Background technique [0002] Mobile communication is an indispensable and important part of modern communication system. Mobile communication base stations and antenna feeder systems have strict requirements on information communication, energy transmission and safe operation, and are indispensable components of mobile communication networks. Due to man-made (such as theft) and natural (such as lightning strikes) and other reasons for the power facilities of the base station and antenna feeder system, the failure of power supply and information transmission directly affects its normal operation and reduces the reliabili...
