Abstract
The utility model relates to a mobile communication portable emergency communication repeater comprising a main machine unit, a power supply unit, a receiving antenna and a transmitting antenna, wherein the main machine unit comprises a radio frequency unit and a monitoring panel; the main machine unit is connected with the power supply unit and respectively connected with the receiving antenna and the transmitting antenna by ultra-flexible cables. In the scene of needing emergency communication, the mobile communication portable emergency communication repeater can reduce the difficulty of selecting points when in emergency installation, and greatly reduce the response time.
Description
[technical field]
The utility model relates to a kind of repeater, is meant a kind of mobile communication portable emergency communication repeater especially.
[background technology]
Traditional repeater is in some emergent occasions, and for example, small space, high telephone traffic region, disaster area happen suddenly, under the not high situation of space isolation, traditional direct discharging station can't satisfy requirement for signal coverage, and traditional repeater volume is big, Heavy Weight is unfavorable for installing and debugging.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of portable emergency communication direct discharging station, in needing the scene of emergency communication, can reduce the difficulty of emergent installing type reconnaissance, has reduced the response time greatly.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of mobile communication portable emergency communication repeater comprises main computer unit, power subsystem, reception antenna, transmitting antenna; Wherein main computer unit comprises radio frequency unit and monitoring panel; Described main computer unit connects power subsystem; Described main computer unit is connected with reception antenna, transmitting antenna respectively by the super flexible cable line.
Described radio frequency unit comprises BS end duplexer, a MS end duplexer and place two-way amplification link between two duplexers; Described two-way amplification link is respectively up link and down link; Described up link and down link comprise a LNA respectively, a upconverter, self-excitation interference eliminated (ICM) digital module, a low-converter, a power amplifier.
Described monitoring panel comprises debugging button, working station indicator, electric weight display screen and LCDs.
Advantage of the present utility model is: owing to adopt digital interference to offset treatment technology, system gain can reach 100dB, and power output can reach 40dBm, and adaptability is strong, can satisfy the covering requirement.The cabinet of whole system adopts small size, portable cabinet, and the antenna-feedback system of lightweight, equipment are convenient for carrying, install simple, are bringing into play positive and far-reaching effect in emergency communication.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model system block diagram.
Fig. 2 is a radio frequency unit schematic diagram in the utility model.
[embodiment]
A kind of mobile communication portable emergency communication repeater as shown in Figure 1, comprises main computer unit, power subsystem, reception antenna, transmitting antenna; Wherein main computer unit comprises radio frequency unit and monitoring panel; Described main computer unit connects power subsystem; Described main computer unit is connected with reception antenna, transmitting antenna respectively by the super flexible cable line.The monitoring panel comprises debugging button, working station indicator, electric weight display screen and LCDs.Main computer unit is a kind of ICS (an Interference Cancellation System self-excitation interference cancelling system); Power subsystem is that colloid battery and water proof type charge controller are formed, and main computer unit is supported multiple supply power mode.Be respectively equipped with reception antenna and transmitting antenna on the top of two sleeve pipe poles, level interval between two sleeve pipe poles is 10～30 meters, isolation can be than complete machine little 15 dB that gain between reception antenna and the transmitting antenna, the repeater main frame is portable packaged type, the repeater main frame through the super flexible cable line respectively with reception antenna, transmitting antenna connects.
As shown in Figure 2, radio frequency unit comprises BS end duplexer, a MS end duplexer and place two-way amplification link between two duplexers; Described two-way amplification link is respectively up link and down link; Described up link and down link comprise a LNA respectively, a upconverter, self-excitation interference eliminated (ICM) digital module, a low-converter, a power amplifier.Antenna in the radio frequency unit receives the downstream signal from the base station, after spuious outside the BS end duplexer filtering band, send into descending LNA and carry out the low noise amplification, faint received signal is brought up to the appropriate signals level, the signal that LNA is come out is through the following change part of descending frequency converter, frequency is changed to medium-frequency IF (70MHZ), the ICM module is carried out AD/DA to the IF signal of input again, digital processings such as estimation of FPGA feedback channel and interference cancellation, IF signal is after treatment sent into going up of descending frequency converter and is become partly, signal on the process after the change is sent into the power amplification link and is carried out power amplification, signal is brought up to enough power levels, again through the outer spurious signal of the duplexer filtering band of MS end, by retransmitting antenna signal is transmitted into service area at last, thereby finishes the dual-use function of descending interference eliminated and power amplification.
Equally, the up course of work and descending similar, just the frequency difference of signal.
The utility model is owing to adopt digital interference to offset treatment technology, and system gain can reach 100dB, and power output can reach 40dBm, and adaptability is strong, can satisfy the covering requirement.The cabinet of whole system adopts small size, portable cabinet, and the antenna-feedback system of lightweight, equipment are convenient for carrying, install simple, are bringing into play positive and far-reaching effect in emergency communication.
