Research on all-optical redundancy networks underground coal mines

In view of the serious environmental interference coal mine underground, inconvenient power supply underground equipment and existence passive serial series number existing F5G network network, explore a new all-optical redundancy technology networking scheme, realize multi-stage light branches mine, Solve problem low optical in anti-interference communication. Based on principle this paper expounds protection mechanism group, designs wide-ranging coverage scheme fiber optic whole through precision calculation analysis. Through laboratory verification roadway simulation experimental data show that can serialization, while ensuring priority reliability gas system. At same time, system are guaranteed; parameter comparison table is suitable for various types mines be used as reference users construction networks.
