Embodiment Construction

[0047] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0048] Such as figure 1 As shown, a method for improving the reliability of underground terminal access described in this embodiment includes:

[0049] Step 1, establish a ground base station to provide various communication services for the ground area;

[0050] Step 2, set up underground signal points to provide various communication services for underground areas;

[0051] Step 3, at the entrance from the ground to the underground, set up a signal receiving and amplifying device to receive and amplify the downlink signal of the ground base station, and feed the downlink signal to the leaky cable located underground;

[0052] Step 4, the leakage cable transmits the downlink signal of the ground base station to t...

Abstract

The invention relates to a method for improving underground terminal access reliability. The method comprises the steps that (1) a ground base station is established, (2) underground signal points are set, (3) a signal receiving and magnifying device is arranged at the position of an inlet from the ground to the underground so that a down-going signal of the ground base station can be received and magnified, the down-going signal is fed into leaky cable located underground, (4) the leaky cable transmits the down-going signal of the ground base station to the underground in a manner of signal leakage, and (5) when an underground terminal sends an up-going signal, the leaky cable receives and transmits the up-going signal to the signal receiving and magnifying device for magnification, and then sends the up-going signal to the ground base station. Further provided is a system for improving the underground terminal access reliability. According to the method and the system for improving the underground terminal access reliability, the signal covered on the ground is introduced to the underground, and therefore simultaneous covering for an underground area position simultaneously through a ground communication device and an underground communication device is achieved, and the method and the system for improving the underground terminal access reliability are low in cost, high in access reliability and simple in construction.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for improving the reliability of underground terminal access. Background technique [0002] For some high-risk coverage scenarios (such as coal mines, etc.), the access reliability of the communication system is high, that is, in the event of a dangerous accident, it is also necessary to ensure that the terminal can be accessed. However, for some private network (such as coal mines, subways, etc.) scenarios, special ground and underground communication equipment are generally used for separate coverage. This will lead to a situation where there is generally only one set of communication equipment covering an area. Once this set of equipment fails or there is a transmission problem, it will cause the terminals in the area to be unable to access; in this case, the inability to access Sometimes it can be fatal. [0003] In order to solve the problem of p...
