Communication method by using light in mines or oil and gas fields and light communication system

Abstract

The invention discloses a communication method by using light in mines or oil and gas fields and a light communication system. The system comprises base station equipment and terminal equipment, wherein the base station equipment and the terminal equipment comprise the following modules: a communication module, a lighting control module and a light receiving module; the communication module is used for coding and modulating the transmission information to obtain the transmission signals, and demodulating and decoding the receiving signals to obtain the transmission information; the lighting control module is used for controlling lighting equipment to transmit the light signals according to the transmission signals, and the lighting signals are spatially reused in the transmission lines; and the light receiving module is used for receiving the light signals to obtain the receiving signals.. According to the invention, the light is utilized to transmit the information, so that the illumination needs of the mines and the oil and gas fields are ensured, the information is transmitted by using the visible light in free space, detonating risks of the radio frequency devices of the communication equipment in coal ash or oil and gas environment are prevented, and the self-healing and anti-damage abilities are realized in the event of failure.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and an optical communication system using light for communication in mines or oil fields. Background technique [0002] In recent years, with the rapid economic growth, my country's energy industry has also been booming, and has entered a high-input, high-efficiency, high-output economic development path. However, in coal mines and oil and gas fields, the safety production situation is still severe. A little carelessness will cause heavy losses to the country and people's lives and property, and pose a major threat to environmental safety. The emergency communication systems for mines and oil and gas fields in the prior art use cables to transmit signals. When there are emergencies such as mine water seepage, gas and petroleum gas explosions, gas and petroleum gas exceeding the standard, and collapse, the power supply is usually cut off, resulting in unexpected pow...
