Description
Technical field
The utility model belongs to communication technique field, more specifically refers to a kind of wireless communication of radio frequency active differential cloth
Number covering system.
Background technique
Currently, the place of some relative closures for example underground parking, subway, railway, airport, station, residential quarters,
Commercial building, stadiums, exhibition center, government organs' building etc., base more severe to the shielding attenuation of wireless communication signals
The covering signal emitted of standing forms many blind areas indoors, or in the region of covering, the covering quality of signal is unstable, makes
It can not normal use at the communication function of certain customers.
In order to solve the above problem, it mostly uses greatly at present and provides information source by base station, indoor distribution system is then introduced by optical fiber
System, indoor distributed system mainly use the equipment such as power splitter, coupler, combiner, indoor passive distribution antenna to form.The system
Equipment composition is more complex, increases the investment of equipment cost, and needs to introduce fiber optic cables transmission, must mention in many occasions
Preceding pre-buried fiber optic cables, increase difficulty of construction.In addition, without monitoring function, operator is difficult to pair the indoor distributed system at present
Indoor distributed system carries out unified management and centralized control.
Utility model content
The utility model provides a kind of radio signal coverage system of radio frequency active differential cloth, and main purpose is to overcome
Existing base station information source needs to introduce interior by fiber optic cables, and indoor distributed system can not monitor, it is difficult to be managed collectively and concentrate and control
The disadvantages of processed.
The utility model adopts the following technical solution:
A kind of radio signal coverage system of radio frequency active differential cloth, including control host, expansion equipment, remote terminal with
And network management monitoring center, the control host are connect by open antenna with base station radio, the control host output end with it is described
The input terminal of expansion equipment connects, and the expansion equipment is equipped with a power supply device, and the output end of the expansion equipment connects respectively
A plurality of remote terminals are connect, each remote terminal is equipped with a whip antenna, and the expansion equipment is short by one
Message server is connect with the network management monitoring center.
Further, between the open antenna and control host, the control host and expansion equipment, described extend set
It is standby to be connected respectively by 3DFB coaxial cable between each remote terminal, the control host and expansion equipment and expansion equipment
3DFB coaxial cable between each remote terminal is all not less than 30 meters.
Further, the model GRMDMU, the model GRMDEU of the expansion equipment of the control host.
Further, the control host is equipped with power supply indicator, power indication lamp and isolation indicator light.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the advantages that
1, the utility model radio signal coverage system, control host couple base station signal by open antenna in the air, so
After being amplified afterwards by expansion equipment, then automatic distribution realizes that remote transmission and seamless coverage, base station signal are kept away to multiple remote terminals
Exempt to access using fiber optic cables, reduces difficulty of construction and cost；And network management monitoring center also passes through short message service server and extension
Equipment connection can carry out overall monitor to whole system, and monitoring information is uploaded to operator's monitor supervision platform, realize unified pipe
Reason and centralized control.
2, the 3DFB coaxial cable controlled between host and expansion equipment and expansion equipment and each remote terminal is not small
In 30 meters, it is ensured that system has optimum Working in outdoor signal intensity satisfaction -75dbm.
Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model.
