Description
Technical field
The present invention relates to a kind of communication system, particularly relate to a kind of emergency communication system for mine production.
Background technology
Because underworkings is long and narrow, the more specific condition that waits of bend can't cover the communication range of whole down-hole by an antenna as ground.This just must make wireless signal can continue in the down-hole by special means.Existing base station radio communication system adopts is main level communication network with the 150MHz-170MHz frequency range, the terrestrial wireless communication system is to set up base-station (BS) at machine room, by radio frequency coaxial-cable signal is guided to the antenna of eminence, realize that the radio communication of certain radius scope covers.For under ground portion, the signal of base-station be by leaky cable to downhole transmitted, for providing uniform field intensity to cover in the tunnel,, can seal in various noises in the air simultaneously simultaneously because in the transmission course of long distance, signal can be decayed.In order to make data that receiving terminal receives near initial data, this just must take certain filtering and indemnifying measure.The compensation of used signal and amplification are the repeaters that adopts the 150MHz frequency range.Because the single base radio area of coverage of the communication system of 150MHz is subject to disturb the restriction with power, can not resembles and set up big net the 450MHz-470MHz trunked communication system.Particularly in built-up urban district or high mountain area with a varied topography, the multipath delay serious interference, covering radius is approximately three, 1/4th of 450MHz cluster net.Cover same zone, the base station number of 150MHz wants ten times over the 450MHz trunked communication system, needs more system equipment, makes system too complicated, and quantities is big, has reduced the fail safe and the reliability of system.In mining tunnel, its applied environment, electric power environmental are more abominable, because there is loose contact in the raceway surface dust with locomotive, to such an extent as to the instability of backflow; Awarding the electricity bow cremates frequently and longer duration with the stringing power cable; Being extensive use of of power equipments such as thyristor convertor more aggravated the clutter noise on the power cable, and these clutter noises and wireless communication signals exist simultaneously, and filter can't solve, and can only let alone to exist, and raises background noise, interfere with communications.And all clutters, the distribution on frequency spectrum is clocklike, promptly near the 180MHz frequency, be watershed a: 50Hz up to the 180MHz frequency, clutter is very abundant, and energy is bigger; Be higher than the 180MHz frequency, clutter spectrum descends rapidly.Owing to leaky cable and power cable parallel lay-up, the clutter product energy of 150MHz frequency is higher than the 450MHz frequency simultaneously; The propagation characteristic of 450MHz frequency is excellent and coupling index 150MHz frequency 450MHz frequency leaky cable is excellent and the 150MHz frequency.This just 150MHz and 450MHz frequency intercom communication efficiency is similar on the ground, and the reason place that differs greatly in the down-hole.Because the communication system of 450MHz frequency range realizes signaling digitlization, integrated, miniaturization, be suitable for the private network mobile communication especially, and be easy to realize networking requirement, so, how will use 450MHz frequency radio communications system in mine is that the dealer pursues, but 450MHz frequency radio communications system only uses (as shown in Figure 1) on the ground at present, does not also use in mine.
Summary of the invention
The object of the present invention is to provide a kind of can effectively cover whole down-hole emergency communication system for mine production.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of emergency communication system for mine production, and it comprises at least one base-station, repeater, leaky cable, the fibre optic data transmission interface; Described base-station is connected with the leaky cable that leads to the down-hole, and the base-station signal, keeps at a certain distance away on the leaky cable of long distance the repeater that a pair of signal carries out filtering and compensation is set to downhole transmitted by leaky cable.
Described base-station has two, connects by the leaky cable that is placed through underworkings between two base-station.
Described repeater is the repeater of 450M frequency range.
Described fibre optic data transmission interface is the interface that relaying and signal switch, and reaches the purpose of Loop Protection.
The present invention also comprises server, switch, monitor terminal, remote control terminal; Described base-station connects by switch-to-server, is connected with the monitor terminal that is used for personnel positioning video monitoring and locomotive tracking between base-station and switch; Described remote control terminal passes through TCP/IP network connection service device, thereby monitor terminal is operated.
After adopting such scheme, the present invention is a 450MHz frequency range communication system, the signal of base-station by leaky cable to downhole transmitted, simultaneously for providing uniform field intensity to cover in the tunnel, and utilize dedicated channel to carry out various transfer of data, constitute a wireless system for transmitting data.For the decay of signal in the transmission course that overcomes long distance and the various noises that can seal in the air, better make data that receiving terminal receives near initial data, the present invention takes certain filtering and indemnifying measure, adopt the repeater of 450MHz frequency range, utilize the various noises in its inner duplexer filtering transmission course, by the controllable gain frequency selective amplifier, useful signal is amplified compensation simultaneously.Because native system utilizes the 450M frequency range to have bandwidth, has realized the voice signal of down-hole, the transmission of data such as locomotive tracking, personnel positioning and track switch control.Ground maneuvers personnel not only can converse with underground operators and trainman, but also can come locomotive and personnel positions under the monitor well according to the software that I take charge of independent development, and conveying track track switch state under the control well.By the cascade of relay system, the 450MHz communication system not only can satisfy the communication service of tunnel 10-100 kilometer, realizes simultaneously that the mine activity in production to underground exploitation takes remote measurement, remote signalling, remote control.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
