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
The present invention relates to a kind of communication system, especially a kind of undershaft communication system.
Background technology
Minepit environment is severe, and potential hazards are many.The communication of down-hole ensures particularly important.Present downhole communication device ubiquity poor stability, configuring dumb, easily causing whole communication network to paralyse when breaking down.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of undershaft communication system, the deficiencies in the prior art can be solved, by rationally arranging position and the quantity of 3 grades of communication architectures, and the repeater that can carry out mutually data transmission being set at each communication terminal, ensure that the stability of communication.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of undershaft communication system, comprise several signal terminals being arranged on aboveground switch He being arranged on down-hole, and several communication terminals, switch and signal terminal adopt Fiber connection, and signal terminal carries out wireless telecommunications with communication terminal by radio-frequency antenna and is connected; Switch and signal terminal are provided with external power source, and each communication terminal is provided with a repeater.
As preferably, described switch and signal terminal are also equipped with stand-by power supply.
As preferably, described signal terminal one has two, is separately positioned on returnairshaft place and winding shaft place.
As preferentially, between described signal terminal and communication terminal, frequency division multiplexing mode is adopted to carry out communication.
The beneficial effect adopting technique scheme to bring is: the present invention, by arranging two signal terminals in down-hole, improves quorum sensing inhibitor intensity, adopts optical fiber to carry out communication between signal terminal and switch, and antijamming capability is strong, and speed is fast.The stand-by power supply of switch and signal terminal improves the stability of whole communication system.When some communication terminals cannot be connected to signal terminal, by repeater, communication data can be transferred to another neighbouring communication terminal, then carry out communication by the communication terminal accepting data with signal terminal and be connected.Substantially increase the unimpeded of downhole communication like this, eliminate signal blind spot.Adopt frequency division multiplexing mode to carry out communication between signal terminal and communication terminal, ensure that the speed of communication, the transfer of data of mobile data terminal can not influence each other transmission rate.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention's embodiment.
In figure: 1, switch; 2, signal terminal; 3, communication terminal; 4, optical fiber; 5, radio-frequency antenna; 6, external power source; 7, repeater; 8, stand-by power supply.
Embodiment
With reference to Fig. 1, the present invention includes several signal terminals 2 being arranged on aboveground switch 1 and being arranged on down-hole, and several communication terminals 3, switch 1 and signal terminal 2 adopt optical fiber 4 to be connected, and signal terminal 2 carries out wireless telecommunications with communication terminal 3 by radio-frequency antenna 5 and is connected; Switch 1 and signal terminal 2 are provided with external power source 6, and each communication terminal 3 is provided with a repeater 7.
It should be noted that described switch 1 and signal terminal 2 are also equipped with stand-by power supply 8.
It should be noted that described signal terminal 2 one has two, be separately positioned on returnairshaft place and winding shaft place.
In addition, frequency division multiplexing mode is adopted to carry out communication between described signal terminal 2 and communication terminal 3.
Operation principle of the present invention is: the present invention, by arranging two signal terminals 2 in down-hole, improves quorum sensing inhibitor intensity, adopts optical fiber 4 to carry out communication between signal terminal 2 and switch 1, and antijamming capability is strong, and speed is fast.The stand-by power supply 8 of switch 1 and signal terminal 2 improves the stability of whole communication system.When some communication terminals 3 cannot be connected to signal terminal 2, by repeater 7, communication data can be transferred to another neighbouring communication terminal 3, then carry out communication by the communication terminal 3 accepting data with signal terminal 2 and be connected.Substantially increase the unimpeded of downhole communication like this, eliminate signal blind spot.Adopt frequency division multiplexing mode to carry out communication between signal terminal 2 and communication terminal 3, ensure that the speed of communication, the transfer of data of mobile data terminal 3 can not influence each other transmission rate.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
