Description
Technical field
The utility model relates to wireless communication technology field, specifically, relates to a kind of NodeB.
Background technology
At present, domestic and international Groups of Mine-used Wireless Communication System mainly contains Leakage Communication System, Induction Communications System, ground through communication system, PHS (Personal Handyphone System) communication system and 3G (well-informed greatly) communication system etc.Wherein, ground through communication system because have that equipment volume is large and heavy, channel capacity is little, ground installation power large, ground-plane antenna difficult arrangement and can only the problem such as one-way communication (ground is to down-hole), so should not Underground Wireless Communication System be used as.Because there is the problem such as sex change energy and series connection relaying poor reliability of combating a natural disaster, so also should not Underground Wireless Communication System be made in Leakage Communication System.Induction Communications System is same because have that volume is large, Heavy Weight, channel capacity are little and the problem such as communication distance is short, so should not make multi-functional Underground Wireless Communication System equally.In addition, PHS (Personal Handyphone System) communication system and 3G (well-informed greatly) communication system, because base station controller and base station non-intrinsically safe explosion-proofing safe, anti-accident ability are poor, base station, down-hole to ground maximum communication distance does not meet the problems such as the requirement of underground communica tion 10 kilometers, are not suitable for Underground Wireless Communication System yet.
Now, along with 3G mechanics of communication maturation and extensively use, simultaneously in order to provide high-quality Communications service to users, 3G communication base station is all set up preparing in each area.Wherein, for the communication module housing being arranged on base station outdoor, because it not only needs in the face of complicated external environment condition, also must meet the inner unique circuit structure of NodeB and wire laying mode, and need to reach index of dispelling the heat preferably, therefore to its structure, there is higher requirement when designing.At present for the machine frame structure of central control unit, normally backboard made by employing monoblock heating panel, the machine frame of this structure owing to not only needing to lay chip circuit plate in machine frame, also need supporting filter etc. is installed, and during the work of chip circuit plate, have amount of heat generation to need heat radiation, the heat that filter produces is but very little need not configure heating panel, therefore heating panel is also adopted not only to reduce the inner space of machine frame the backboard of filter, also make the production cost of housing higher, thus make heating panel more easily damaged.And, the mining wireless communication technology is because of the restriction of the problems such as handover mechanism, information security and anti-interference, transmitting power and stand-by time in the market, cause voice call quality poor, switch easy packet loss, the problems such as poor anti jamming capability, stand-by time are short, have a strong impact on the underground work safety of workman.
For the problem in above-mentioned correlation technique, at present effective solution is not yet proposed.
Utility model content
The utility model proposes a kind of NodeB, poor to overcome voice call quality of the prior art, switch easy packet loss, poor anti jamming capability, stand-by time are short, complex structure and be awkward the problems such as use.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of NodeB, comprise wireless receiving module, optical cable transmission module, Double-strand transmission module and power supply, described wireless receiving module, described optical cable transmission module and described Double-strand transmission module and central control unit are bi-directionally connected, and described power supply is connected with described central control unit is unidirectional.Wherein, described wireless receiving module comprises transducer, transceiver, demodulator, receiver, synthesizer, comparator and processor, and described wireless receiving module and described central control unit are bi-directionally connected by described processor.
Further, the optical signal interface quantity of described optical cable transmission module is 2, and maximum transmission distance is 20km; The twisted pair signal interface quantity of described Double-strand transmission module is 1, and maximum transmission distance is 5km.
Further, described base station meets at most the communication simultaneously of 8 mobile phones.
Further, described base station is connected by two core twisted-pair feeders or optical cable with between base station, and wireless WIFI signal carries out data interchange by two directional antennas.
The beneficial effects of the utility model: by adopting 3G technology and networking mode thus make its place system have stronger autgmentability and upgrading space flexibly, and then make this system not only be not easy net under mine laneway operational environment, and antijamming capability is strong, voice call effect and downhole wireless covering effect of signals good, effectively ensure that the safety and efficiency of workman's underground work.
