Abstract
The invention discloses an underground wireless communication system, which comprises wireless interphones. The wireless interphones communicate with photoelectric conversion modules through wireless communication modules. The photoelectric conversion modules are connected with a single mode optical fiber, and communicate with a ground monitoring center. Relays are arranged at intervals on the single mode optical fiber, and are used for filtering received signals, and amplifying useful signals. Wireless signals of the interphones are transmitted and converted through the communication modules and the photoelectric conversion modules, and are divided into two paths of optical signals for output, so that the long-distance transmission stability and long-distance transmission of the signals are ensured; and by the relays, communication stability, anti-interference performance and security are ensured, the aim of real-time communication is fulfilled, underground conditions can be mastered at any time, and safety production is effectively guaranteed.
Description
Technical field
