Description
Technical field
The utility model relates to the mobile phone signal trunking, specifically is a kind of mobile phone feeble field district compensation equipment, makes the faint zone of any mobile phone signal field intensity obtain reliable and stable communication service.
Background technology
Fast development along with mobile communications network; Network coverage just constantly enlarges; But owing to the exploitation of various buildings, traffic route, consequently indoor mobile communication still exists some weak links can not satisfy user's demand, mainly has following problems at present.
1, blind area: signal is accepted sensitivity through being lower than mobile phone after consuming, and causes mobile phone communication bad.
2, weak district: signal is accepted sensitivity through consuming near mobile phone, causes mobile phone communication bad.
3, battleground: mainly be the high-rise district wireless signal from a plurality of sub-districts, and the unstable reflected signal of multiaspect ground, metope causes shielding to be switched, and has a strong impact on the undesired communication of mobile phone.
4, busy district: mainly be the big area of telephone traffic, the base station capacity is difficult to satisfy the communication needs, and the user can't carry out proper communication by access to mobile network.
Mobile phone feeble field district compensation equipment can be realized the wireless coverage of internal home network; Improve speech quality; But existing mobile phone feeble field district compensation equipment does not possess the automatic gain function, and is still in running order under the place signal is mourned in silence situation, not only increased power consumption and reduced working life yet.
The utility model content
The utility model technical problem to be solved provides a kind ofly can discern feeble field district mobile phone signal intensity automatically; Automatically collocating uplink gain and downstream signal power level possesses the place of identification signal and mourns in silence and make it be in the mobile phone feeble field district compensation equipment of resting state.
The described a kind of mobile phone feeble field of the utility model district compensation equipment; The uplink and downlink part that connects antenna, external antenna in it comprises and connect two antennas; Wherein ascender comprises first duplexer that connects antenna in the connection; First duplexer connects up LNA (low noise amplifier), upstream filter, up isolator, up PA (power amplifier) and second duplexer more successively, and second duplexer is connected with outer reception antenna again; Descender comprises the descending LNA that connects second duplexer, and descending LNA connects downstream filter, descending isolator, descending PA to the first duplexer successively; Also be connected to signal detector and controller in the first duplexer rear end, wherein the input of signal detector connects up PA and descending PA respectively, and the output of controller connects up PA and descending PA respectively.
Mobile phone feeble field district compensation equipment is that a kind of two-channel wireless communication feeble field is mended equipment of blind; After external antenna receives in descending LNA, to amplify and handle to the call signal of base station; Form radio-frequency power by descending PA again and radiate through internal antenna through first duplexer, after the cellphone subscriber receives call signal, reply the callback signal and receive and amplify by up LNA by the interior antenna that connects; Launch through external antenna through up PA output, the base station receives its signal and has promptly accomplished the blind task of mending.The utility model has increased the test section, and its effect is the intensity that receives signal according to external antenna, judges the required power of passback output, does not call out and the passback mobile phone signal if having, and then controls PA constant power device and is in resting state automatically.
Major function:
1) up turn-off function
Mobile phone feeble field district compensation equipment will detect area of coverage user automatically; If do not detect the user when in use in the overlay area; To automatically shut down up amplification channel, and guarantee network is not produced interference, when in network, detecting customer call; Automatically open up amplification channel, guarantee that the user well uses.
2) digital ALC
Device interior possesses digital ALC and simulation ALC function, and the dynamic auto adjustable range that gains reaches 20dB, and system ALC dual redundant guarantees system's high reliability and high stability.
3) Self-excitation Detection deixis
After mobile phone feeble field district compensation equipment installs; Can detect the isolation of antenna automatically; If the installation requirement of the discontented pedal system of isolation between antennas, equipment will have indicator light indication will be provided, and automatic control equipment reduces gain; Till equipment did not produce the amplification self-excitation, protection device security and network were interference-free.
4) the up-downgoing debugging that links automatically
After system installs energising, system will detect input power automatically, and the size of control power output; After calculating the descending gain of system, the up gain of automatic adjustment system, the amplification balance of maintenance system; The realization equipment up-downgoing debugging that links automatically; The gain of automatic control system is less than the path attenuation of signal, guarantees that mobile phone feeble field district compensation equipment does not have any interference noise to network and brings into, guarantees that a base station can be with more a plurality of mobile phone feeble fields district compensation equipment.

Embodiment
As shown in Figure 1; The uplink and downlink part that connects antenna, external antenna in the utility model comprises and connect two antennas; Wherein ascender comprises first duplexer that connects antenna in the connection; First duplexer connects up LNA, upstream filter, up isolator, up PA and second duplexer more successively, and second duplexer is connected with outer reception antenna again; Descender comprises the descending LNA that connects second duplexer, and descending LNA connects downstream filter, descending isolator, descending PA to the first duplexer successively; Also be connected to signal detector and controller in the first duplexer rear end, wherein the input of signal detector connects up PA and descending PA respectively, and the output of controller connects up PA and descending PA respectively.
Its design philosophy be with detect, monitoring is core, each functional circuit is the control technology at intercommunication terminal, incoming call, exhalation level of RF signals and antenna standing wave is gathered, is isolated and amplify, with detection and the monitoring of realization to radiofrequency signal.Equipment can determine the operating state such as power setting, dormancy of incoming call exhalation radio frequency output according to detection signal, thereby has improved the Electro Magnetic Compatibility of equipment and the reliability of system greatly.
