Problems solved by technology

Since the communication system in the 450MHz frequency band realizes digitalization, integration and miniaturization of signaling, it is especially suitable for private network mobile communication, and it is easy to meet the networking requirements. Therefore, how to use the 450MHz frequency wireless communication system in mines is what the industry is pursuing. , but the current 450MHz frequency wireless communication system is only used on the ground (such as figure 1 shown), not yet used in mines

Embodiment Construction

[0015] like figure 2 As shown, the present invention is a mine production emergency communication system, which includes a server 1, a switch 2, a monitoring terminal 3, a base station 4, a repeater 5, a leakage cable 6, and a remote control terminal 7.

[0016] Described base station 4 is connected with server 1 through switchboard 2, is connected with the monitoring terminal 3 that is used for personnel positioning video monitoring and locomotive tracking between base station 4 and switchboard 2; Described base station 4 is connected with lead to underground Leaky cable 6, the base station 4 signal is transmitted downhole through the leaky cable 6, and a pair of repeaters 5 for filtering and compensating the signals are arranged at a distance on the long-distance leaky cable 6, and the repeater 5 is a 450MHz frequency band Repeater, through the cascading of the relay system, the 450MHz communication system can meet the communication service of 100 kilometers in the roadway....

Abstract

The invention discloses a system for emergency communication in mine production which includes a server, an exchanger, a monitoring terminal, a base station, a repeater and a leakage cable; the base station connects with the server through the exchanger, the monitoring terminal for location video monitoring person and tracking vehicle is connected between the base station and the exchanger; the base station connects with the leakage cable leading to the mine, the base station sends signal to the mine through the leakage cable, a pair of repeaters are set at a certain distance away on the leakage cable with long distance for processing filtering and compensating to signal. The method uses the repeater with 450MHz frequency band which can filter various noise in transmitting process by using the inner duplexer, and process amplifier compensation to the useful sign. The 450M frequency band has wide band that realize data transmition for voice signl under the mine, vehicle tracking, person location and railroad switch control.

Description

technical field [0001] The invention relates to a communication system, in particular to a mine production emergency communication system. Background technique [0002] Due to the special conditions such as narrow and long underground roadways and many curves, it is impossible to cover the entire underground communication range with one antenna like on the ground. This requires special means to enable the wireless signal to continue underground. The existing base station wireless communication system uses a basic level communication network in the 150MHz-170MHz frequency band. The ground wireless communication system is to set up a base station (BS) in the computer room, and lead the signal to a high antenna through a radio frequency coaxial cable to realize Wireless communication coverage within a certain radius. For the underground part, the signal of the base station is transmitted underground through leaky cables, and at the same time provides uniform field strength co...
