Description
Technical field
The utility model relates to communication product, specifically, relates to a kind of double antenna cordless telephone.
Background technology
At present, cordless telephone day by day miniaturization, ultrathin and employing metal shell etc., and the handset of cordless telephone adopts is the technology of built-in single antenna, when using such cordless telephone, position limitation residing for single antenna or be subject to the impact of complicated shell, cause the signal weaker receiving machine tool, affect speech quality; When its Received signal strength weak to a rated value time, handset for guaranteeing that communication distance and communication quality increase transmitting power automatically, thus causes radiation to increase, the increase of power consumption.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of double antenna cordless telephone, and to overcome, to receive machine tool signal by handset aerial position affects weak, the problem that radiation is high, power consumption is high, ensures communication quality.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of double antenna wireless telephone set, comprise machine tool and handset, the diverse location of described handset shell is provided with two antennas, the diode that described handset inside is also provided with two common cathodes and the high frequency Transmit-Receive Unit, baseband processing unit, the primary processor that are electrically connected successively, described antenna output end is electrically connected on the anode of diode respectively, the negative electrode of described diode and the input of high frequency Transmit-Receive Unit are electrically connected, and the anode of described primary processor output and diode is electrically connected.
Further illustrate, described diode is high-frequency diode.
Compared with prior art, the utility model has following beneficial effect: adopt the inner diverse location near shell of handset to be provided with two antennas, make handset when receiving machine tool transmission signal by the impact of aerial position, the signal receiving machine tool is strong, ensure speech quality, thus cordless telephone enters the probability of high power transmission in a power-save mode and the time all can greatly reduce, thus reduce the power consumption of handset, increase the service time of battery, reduce electromagnetic radiation power, reduce radiation, meet environment protection requirement.
Accompanying drawing explanation
Fig. 1 is for illustration of the circuit theory schematic diagram of the utility model embodiment.
Parts title and sequence number in figure: 1-antenna 2-diode 3-high frequency Transmit-Receive Unit 4-baseband processing unit 5-primary processor
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection range of the present utility model and range of application:
As shown in Figure 1, a kind of double antenna wireless telephone set, comprise machine tool and handset, the diverse location of described handset shell is provided with two antennas 1, such as antenna 1 is positioned at two sides of the adjacent of handset shell 2 or opposition, the diode 2 that described handset inside is also provided with two common cathodes and the high frequency Transmit-Receive Unit 3 be electrically connected successively, baseband processing unit 4, primary processor 5, described antenna 1 output is electrically connected on the anode of diode 2 respectively, the negative electrode of described diode 2 and the input of high frequency Transmit-Receive Unit 3 are electrically connected, the anode of described primary processor 5 output and diode 2 is electrically connected.Described diode 2 is high-frequency diode.Described high frequency Transmit-Receive Unit 3 is for receiving and sending signal, and described baseband processing unit 4 is responsible for data processing and storage, and major function is baseband coding/decoding, acoustic coding and speech coding etc.Described primary processor 5 is for the computing of data, control and storage.
The diverse location of handset shell is adopted to be provided with two antennas 1, make handset when receiving machine tool transmission signal by the impact of antenna 1 position, the signal receiving machine tool is strong, ensure speech quality, thus cordless telephone enters the probability of high power transmission in a power-save mode and the time all can greatly reduce, thus reduce the power consumption of handset, increase the service time of battery, reduce electromagnetic radiation power, reduce radiation, meet environment protection requirement.Adopt high-frequency diode, switching speed is fast, self-reparability good, and operating frequency is high.
The utility model double antenna cordless telephone course of work is as follows: double antenna cordless telephone in the course of the work, primary processor 5 can select from the antenna of two in handset 1 wherein one as main antenna, other one is slave antenna.High-frequency signal sends and receives first from main antenna; During main antenna work, the signal that high frequency Transmit-Receive Unit 3 receives is analyzed by primary processor 5, judges the power of signal.When Received signal strength is strong, the using state maintaining main antenna is constant; When detecting that the Received signal strength of main antenna is faint, the slave antenna short time can connect by primary processor 5, strong and weak with the Received signal strength detecting slave antenna, can not interrupt the operating state of main antenna in detection time.The receipts that primary processor 5 determines slave antenna connect signal stronger than main antenna time, the use of main antenna can be interrupted, connect simultaneously and use slave antenna; Slave antenna in the process used, primary processor 5 also can the Received signal strength of real-time judge two strip antenna 1 strong and weak, to judge and to select the antenna 1 that wherein signal is strong to use.
More than that the utility model double antenna cordless telephone is set forth; the utility model is understood for helping; but execution mode of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
