Detailed description of the invention
In order to technical scheme is explained further, below by specific embodiment, the present invention is explained in detail
State.
As it is shown in figure 1, the present invention provides a kind of transmitter receiver, including transmitter receiver body, described transmitter receiver body has shell,
And MCU controller 1, baseband processor 2, high frequency divider 3, MIC mike 4 and the loudspeaker that integrated installation is in shell raise one's voice
Device 5.Transmitter receiver body is received by antenna and sends signal.MCU controller 1 respectively with baseband processor 2 and high frequency divider 3
Being bi-directionally connected, antenna passes sequentially through low pass filter, TX/RX handover module and high frequency amplifying module and is connected to Base-Band Processing
The input of device, antenna is connected to the input of high frequency divider also by low pass filter simultaneously.The output of MCU controller 1
End is directly connected in horn-type loudspeaker 5 by audio amplification block, or, the outfan of MCU controller 1 passes sequentially through voice reporting
Number module and audio amplification block are connected to horn-type loudspeaker 5.The outfan of baseband processor 2 is also by audio amplification block even
It is connected to horn-type loudspeaker 5.MIC mike 4 is connected to the input of baseband processor 2 by words amplification module.Baseband processor 2
Outfan passes sequentially through excitation amplification module, promotes amplification module, power amplifier module, TX/RX handover module and low-pass filtering
Device is connected to antenna.
High frequency divider 3 has three optional frequency dividing ratios, respectively 64 frequency dividings, 128 frequency dividings and 256 frequency dividings.High frequency divides
The frequency dividing ratio of device 3 selects to perform to be controlled by the driving of MCU controller 1 with frequency dividing.MCU controller 1 has memorizer, can be used for counting
According to storage.This memorizer is bi-directionally connected with MCU controller 1.The outfan of MCU controller 1 connects LCD display 6,
LCD display 6 is located on the shell of transmitter receiver body.The present invention is also associated with power module, power module be whole intercommunication
The normal work of machine provides working power.And on the output loop of power module, it is provided with power on off switch, to realize intercommunication
The keying of machine.MCU controller 1 is preset with three frequency bands corresponding with the three of high frequency divider 3 optional frequency dividing ratios.Base
Provided with processor 2 can record dumb sound frequency according to radiofrequency signal.Function conventional in being additionally provided with industry on the shell of transmitter receiver body
Key, can realize the regulation etc. of volume.
When receiving signal, antenna receives the radiofrequency signal from the other side's transmitter receiver, and this radiofrequency signal is through low pass filter
Enter high frequency divider 3, carry out rectification by high frequency divider 3, sine wave is made into square-wave signal, then square-wave signal is sent
To MCU controller 1, radiofrequency signal is used for quickly detecting by MCU controller 1, primarily determines that its rf frequency falls within above three
Which section in frequency band, thus select corresponding frequency dividing ratio, and this selection information is sent to high frequency divider 3, high frequency
Frequency divider 3 performs the fractional frequency signal of MCU controller 1, divides radiofrequency signal, and after frequency dividing terminates, high frequency divider 3 will divide
Radio-frequency information after Pin issues MCU controller 1, MCU controller 1 finally accurately record the radio frequency frequency after its frequency dividing
Rate, data are stored in memorizer, and show in LCD display 6.
Meanwhile, the radiofrequency signal that antenna receives is through low pass filter, after carrying out TX/RX switching and High frequency amplification further
Entering baseband processor 2, the radio-frequency information after frequency dividing is sent to baseband processor 2, baseband processor 2 basis by MCU controller 1
This radio-frequency information records the dumb sound frequency of received radiofrequency signal, and baseband processor 2 is by the dumb sound frequency of this radiofrequency signal
Being sent to MCU controller 1, data are stored in memorizer, and show in LCD display 6.
Radiofrequency signal changes into audio signal through MCU controller 1, and audio signal is successively through speech number resume module and sound
Frequency conducts to horn-type loudspeaker 5 after amplifying, it is achieved speech number.
When sending signal, sound is incoming from MIC mike 4, and MIC mike 4 converts audio signals into the signal of telecommunication, passes through
Words amplification module carries out words and puts process, and sends to baseband processor 2.Exported by the outfan of baseband processor 2 further, warp
Excitation is amplified, is promoted amplification, power amplification, TX/RX switching and low pass filter to be sent to antenna after processing, then via antenna
Launch.
Compared with conventional art, the present invention is provided with LCD display 6, can directly display the radio frequency frequency from the other side's transmitter receiver
Rate and dumb sound frequency.Create conditions for the proper communication between different transmitter receivers, other transmitter receivers can by this rf frequency and
Dumb sound frequency is arranged accordingly, and engages in the dialogue with this transmitter receiver.
Further, the present invention arranges high frequency divider 3, is divided by high frequency divider 3, and then changes into grazing shot
Again and again rate, to reduce related electronic devices, such as the performance requirement of MCU controller 1, reduces production cost.
Above-described embodiment and accompanying drawing the product form of the non-limiting present invention and style, any art common
