Description
Technical field
The utility model relates to the GSM repeater, particularly a kind of energy-conservation GSM repeater.
Background technology
GSM full name is: Global System for MobileCommunications, Chinese is global system for mobile communications, be commonly called as " Global Link ", it is a kind of mobile communication technology standard that originates from Europe, it is second generation mobile communication technology, its exploitation purpose is to allow all parts of the world can use a mobile telephone network standard jointly, allows the user use a mobile phone just can manage it all over the whole world.
Gsm system adopts the mobile communication technology of time division multiple access (TDMA), and the GSM Mobile communication direct base station is actually a kind of two-way communication amplifier, plays a part to extend base station range and mends blind.Because the overlay area of which kind of wireless communication all will produce weak signal area and blind area, and for some remote districts and the fewer blind area of user, the construction cost of base station is higher, and the construction of infrastructure is also comparatively complicated.Simultaneously, current mobile communication market presents the situation that maintains sustained and rapid growth, and each operator is in order to satisfy the demand of user to network, and is increasing again to the scale of investment of network.Therefore provide a kind of cost low, build and have simply, but that base station functions, cost-effective equipment--the repeater is necessary.Therefore, there is important effect the GSM repeater in the GSM networking.
For general GSM repeater, its power consumption is mainly produced by power amplifier, its power consumption accounts for more than 80% of whole repeater equipment power consumption, its power amplifier also is an operate as normal under the situation of user's communication not having in present GSM repeater, particularly in the lower areas of telephone traffic such as night, remote countryside areas, consequent power consumption is very big, and is uneconomical, under national energy situation in short supply, cause the waste of certain energy.And along with the expansion of network size, the quantity of repeater increases fast.So, guaranteeing the network coverage, when satisfying the user, need a kind of energy-conservation GSM repeater to network requirement.
The utility model content
In order to address the above problem, the utility model has been announced a kind of energy-conservation GSM repeater, comprise reception antenna, forwarding antenna, duplexer, low noise amplifier, power amplifier, described GSM repeater also comprises time delay device, GSM time slot power wave detector, the time slot on-off controller, the low noise amplifier output is connected with the time delay device input with GSM time slot power wave detector respectively, the time delay device output is connected with the power amplifier input, GSM time slot power wave detector output is connected with time slot on-off controller input, and time slot on-off controller output is connected with the power amplifier input.
By detecting the time slot power of GSM repeater up-downgoing input signal, judge whether the GSM time slot is occupied, if the occupied bias voltage of then opening the up and down power amplifier of time slot, there is not occupied bias voltage of then closing power amplifier, by the operating time of dynamic control power amplifiers, directly effectively reduce the power consumption of repeater.
By the use delayer GSM signal main signal is delayed time simultaneously, make the GSM coupled signal by after the detection of GSM time slot wave detector and judging, at the bias voltage of main signal arrival amplifier front opening up and down power amplifier, the assurance main signal is not lost.
Thereby when guaranteeing network, significantly reduced the repeater power consumption, energy-conservation, reduced the repeater network cost, the energy-conservation while has also reduced the caloric value of repeater and has slowed down the aging speed of main devices, prolongs the service time of amplifier.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
For the easier quilt of the utility model is understood, below in conjunction with Fig. 1 to being done more detailed description by utility model.
The utility model has been announced a kind of energy-conservation GSM repeater.Comprise reception antenna 6, forwarding antenna 7, duplexer 8, low noise amplifier 5, power amplifier 4, described GSM repeater also comprises time delay device 1, GSM time slot power wave detector 2, time slot on-off controller 3, low noise amplifier 5 outputs are connected with time delay device 1 input with GSM time slot power wave detector 2 respectively, time delay device 1 output is connected with power amplifier 4 inputs, GSM time slot power wave detector 2 outputs are connected with time slot on-off controller 3 inputs, and time slot on-off controller 3 outputs are connected with power amplifier 4 inputs.
Signal enters up-downgoing low noise amplifier 5 after receiving by dual-mode antenna 6,7, and after the up-downgoing small-signal was amplified, main signal entered time delay device 1.Secondary signal detects the GSM time slot power by being coupled into GSM time slot power wave detector 2 by GSM time slot power wave detector 2 simultaneously.Time slot on-off controller 3 is a comparator, presets a fixedly comparison value.After GSM time slot power wave detector 2 detected the GSM time slot powers, time slot on-off controller 3 was by the comparison of preset value and detected value, then opened the bias voltage of power amplifier 4 as if detected value greater than preset value, otherwise, just close the bias voltage of power amplifier 4.More definite says, time slot on-off controller 3 compares by preset value and detected value, when detected value is worth greater than preset value output one, if detected value is exported another value less than preset value, controls the switch of bias voltage thus.
Main signal is by time delay device 1, and its time delay is 3～5 microseconds, and secondary signal is about 1 microsecond by the time delay that is coupled into GSM time slot power wave detector 2, and the laggard input time slot on-off controller 3 of detection judges that the time with switch is about 1 microsecond.Thus, before main signal arrives power amplifier 4 through time delay device 1 back, the bias voltage of power amplifier 4 is being opened in advance or closed, guaranteeing that signal can not lose, also reducing the power consumption of repeater.
