Fig. 2 is the structural representation of near-end machine;
Fig. 3 is the structural representation of remote termination.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As a kind of execution mode of the present utility model, consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises GSM base station, near-end machine and a plurality of remote termination, described near-end machine is provided with transmitting antenna, remote termination is provided with reception antenna and cover antenna, also comprise monitoring unit, described GSM base station links to each other with the near-end machine by coupler, described near-end machine comprises radio frequency duplex filtration module, digital frequency-selecting local module, intermediate frequency duplex filtration module, and described digital frequency-selecting local module is provided with the near-end monitoring module; Described remote termination comprises intermediate frequency duplex filtration module, digital frequency-selecting remote end module and radio frequency duplex filtration module, described digital frequency-selecting remote end module is provided with the remote monitoring module, described near-end monitoring module all links to each other with monitoring unit with the remote monitoring module, and described digital frequency-selecting local module links to each other with intermediate frequency duplex filtration module through descending intermediate frequency power amplifier; Be provided with up radio frequency power amplification modules and noise suppression module between digital frequency-selecting local module and the radio frequency duplex filtration module, described digital frequency-selecting remote end module links to each other with radio frequency duplex filtration module through the downlink radio frequency power amplifier; Be provided with up intermediate frequency power amplifier module and noise suppression module between digital frequency-selecting remote end module and the intermediate frequency duplex filtration module.
GSM signal shift frequency is carried out the system of long-distance transmissions to the intermediate frequency frequency range.At the near-end machine GSM frequency band signals is converted to the 230MHz frequency range, signal is reduced in former frequency range, carry out covering behind the linear amplification at remote termination.The Gain Adjustable scope of this system is greater than 60dB, and maximum gain can reach 110dB, and debugging is convenient; Applied widely; System's diffracting power is strong, after diffraction is crossed the barrier that is higher than 50 ~ 70 meters on antenna, still can carry out good covering to the area of coverage in the practical application, is particularly suitable for areas such as dense city, mountain region, forest, hills.
Solving traditional GSM network puts with tower, zoom out solution mountain area or personnel inhabitation and relatively disperse local communication issue, described near-end monitoring module all links to each other with monitoring unit with the remote monitoring module, realized the operating state of real-time monitoring near-end machine and remote termination, brought certain convenience for staff's maintenance, be provided with noise suppression module between digital frequency-selecting local module and the radio frequency duplex filtration module, when being provided with noise suppression module between digital frequency-selecting remote end module and the intermediate frequency duplex filtration module and can detecting up nothings business automatically, software can carry out upstream noise control, can eliminate the interference of upstream noise to the base station, one drags the time marquis of many remote terminations, and advantage is more obvious.
