The another structure schematic diagram of signal intensifier that Fig. 3 provides for the embodiment of the present application.
Embodiment
Below in conjunction with the accompanying drawing of the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those skilled in the art are not paying the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the application's protection.
Referring to Fig. 1, the signal intensifier that the embodiment of the present application provides can comprise: the exterior aerial 1, signal amplifier 2 and the domestic aerial 3 that connect successively.
Above-mentioned exterior aerial, signal amplifier and domestic aerial have formed Miniature repeater, and wherein exterior aerial can be used as the donor antenna of repeater, and domestic aerial can be used as the retransmitting antenna of repeater.Wherein, donor antenna can pick up the base station signal in the public network, and signal amplifier can amplify base station signal, then utilize the base station signal after retransmitting antenna will be amplified to be transferred to collecting device, thereby realized improving public network signal intensity, strengthening the purpose that collecting device obtains the dynamics of signal.
Below, will be take domestic GSM public network as example, the application's technical scheme is elaborated.960MHz and two frequency ranges of 1800MHz that the GSM public network adopts, now carry out in detail with the 960MHz frequency range:
Applicable cases according to reality is different, and in other embodiment of the application, the specific design that above-mentioned signal strengthens equipment is as follows:
A, for former public network signal weak strength but stable applicable cases:
In such cases, general uplink communication can automatically be regulated by the GPRS module and transmit, and therefore, only need to amplify the base station signal of downgoing communication and process, and domestic aerial and/or chamber antenna can adopt whip antenna.
After will receiving the signal amplification, also need to reduce the noise effect of self, otherwise the noise effect of self will cause communication undesired.Therefore, after base station signal is amplified, also need to be with logical frequency-selective filtering to process to the frequency of downgoing communication again, the downgoing communication frequency of GSM is 935～954MHz, and frequency-selecting is amplified by overpower, sends by domestic aerial again.
Therefore, in the case, referring to Fig. 2, above-mentioned domestic aerial 3 comprises the first domestic aerial 31, and above-mentioned signal amplifies 2 devices and comprises noiselike signal amplifier 21, the first frequency-selecting filter 22, the first power amplifier 23.And exterior aerial 1, noiselike signal amplifier 21, the first frequency-selecting filter 22, the first power amplifier 23 and the domestic aerial 31 of being connected connect successively.
B, for the strong but unsettled applicable cases of former public network signal intensity:
The appearance of this situation, mostly because collecting device is in the plotted point of two or more base stations, each base station all provides certain signal strength signal intensity, but all not high enough, the solution of this kind situation and the solution of above-mentioned situation A are similar, but need to set up an arc signal reflex sheet at exterior aerial 1, allow the strongest base station direction of its directional signal, to reach the directed purpose of selecting.
C, for the former public network signal intensity applicable cases that is nothing:
For example, some local signal shielding is relatively more severe, and may cause former public network signal intensity is the appearance of nil case.At this moment, not only descending base station signal needs to amplify, and the upward signal that collecting device sends also needs to amplify the normal remote meter reading work of just finishing.Therefore, need to be designed to the signal intensifier to have the small base station function this moment, and keep scope and can constrain in 0.5 square meter.
Therefore, referring to Fig. 3, above-mentioned domestic aerial 3 also comprises the second domestic aerial 32, and above-mentioned signal amplifier 2 also can comprise the second frequency-selecting filter 24 and the second power amplifier 25.Above-mentioned exterior aerial 1, the second power amplifier 25, the second frequency-selecting filter 24 and the domestic aerial 32 of being connected can connect successively.Certainly, also can be with the location swap of the second power amplifier 25 and the second frequency-selecting filter 24.Therefore not to repeat here.
As seen from Figure 3, up link is compared with down link, up link is not used the noiselike signal device, this be because the antenna of the second domestic aerial 32 and collecting device when mounted relative position fix, direction is clear and definite, therefore, the signal that the second domestic aerial 32 receives is relatively strong, thereby can save the noiselike signal amplifying element.The uplink communication frequency of GSM is 890～909MHz.Above-mentioned the first domestic aerial 31 and the second domestic aerial 32 can be integrated.
In the C situation, domestic aerial and exterior aerial can adopt whip antenna, and in case of necessity, domestic aerial and exterior aerial all can be set up arc signal reflex sheet and improve signal strength signal intensity and reduce disturbance.
For example, can increase an arc signal reflex sheet at domestic aerial and collecting device antenna limit separately, this arc signal reflex sheet can adopt aluminum material, and its height is few with the difference in height of each self-corresponding antenna.When mounted, allow signal intensifier and collecting device two arc signal reflex sheets just in time cambered surface make the signal between the two the strongest to cambered surface, reduce the signal transmission loss between signal intensifier and the collecting device as far as possible and reduce to infect.
In addition, if signal is too poor, exterior aerial 1 can adopt Yagi antenna.
It should be noted that and consider the external radiation interference, the signal intensifier among above-mentioned all embodiment also can comprise metal-back, above-mentioned exterior aerial, domestic aerial and power supply can be placed in outside the metal-back, and all the other devices are placed in the metal-back.In other words, whole signal intensifier all places the metal-back of shielding except antenna and power supply, disturbed by external radiation to reduce circuit.
In addition, be to reduce the self-excitation of antenna, when mounted, basic principle is that the antenna of domestic aerial and collecting device is as far as possible close, and the distance between domestic aerial and the exterior aerial should be at least 3 times of distance between the antenna of domestic aerial and collecting device.
Need to prove, each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the application.It will be easy to do concerning those skilled in the art that the non-creativeness of these embodiment is revised, and General Principle as defined herein can in the situation of the spirit or scope that do not break away from the application, realize in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will protect principle disclosed herein and features of novelty the widest consistent scope.
