Abstract

The invention discloses a down-hole communication system, comprising a switch arranged above a well, a plurality of signal transfer stations arranged under the well and a plurality of mobile communication terminals, wherein the switch is connected with the signal transfer stations via an optical fibre; the signal transfer stations and the mobile communication terminals are communicated in a wireless manner via an RF antenna; the switch and the signal transfer stations are provided with external power supplies, and each mobile communication terminal is provided with a repeater. The system of the invention overcomes the shortcoming of the prior art and ensures the stability of the communication via rationally arranging position and quantity of three-level communication architectures and arranging the repeaters, which can be used for carrying out data transmission mutually, at the mobile communication terminals respectively.

Description

technical field [0001] The invention relates to a communication system, in particular to an underground communication system. Background technique [0002] The mine environment is harsh and there are many potential risk factors. Underground communication guarantee is particularly important. The current underground communication devices generally have poor stability and inflexible configuration, which will easily cause the entire communication network to be paralyzed when a failure occurs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an underground communication system, which can solve the deficiencies of the prior art, by reasonably setting the position and quantity of the three-level communication framework, and setting up a middle ground for mutual data transmission in each mobile communication terminal The repeater ensures the stability of communication. [0004] In order to solve the above technical pro...
