Road.The radiofrequency signal module is used to produce radiofrequency signal;The frequency error factor module is used to control radiofrequency signal
Module produces the radiofrequency signal of different frequency;The signal emission module is used to launch radiofrequency signal;The signal
Receiver module is used to receive radiofrequency signal;The frequency matching module is used to judge that the radio frequency signal frequency for receiving is
It is no identical with audio range frequency residing for receiving terminal;The audio frequency output channel is used to export and receiving terminal wave band same frequency
The voice signal loaded in rate.
Improved as one kind of said system, penetrated according to following two Mode Launch for |input paramete drives terminal
Frequency signal:Pattern one, the parameter of input is used for triggering terminal and is sent out according to a permanent order, difference on the frequency and time difference
Send radiofrequency signal;Pattern two, the parameter of input is used for the radio frequency letter that drives terminal preferentially sends some CFs
After number, then launch radiofrequency signal by pattern one.
The present invention compared with prior art, with advantages below:(1) terminal launches the radio frequency of different frequency automatically
Signal is matched for receiving terminal, and without artificial operation, operation is simple, and driver's sight line can be avoided to shift institute's band
The danger for coming;(2) in order to be quickly that daytime is short and receiving end signal is matched, one group of CF can be set
Radiofrequency signal preferential emission matching.
The present invention is described further with reference to Figure of description.

Specific embodiment
With reference to Fig. 1, a kind of method of occupancy receiving terminal channel playback terminal sound, the method is applied to receiving terminal
Under FM FM signals modulation working condition, and on a certain channel.The method is comprised the following steps:
Step 1, the terminal to receiving terminal channel to be connected receives the instruction for taking receiving terminal channel;
Step 2, sends a frequency RF signal in receiving terminal;
Step 3, receiving terminal is matched to the radiofrequency signal for sending with the frequency on the channel residing for itself;
Step 4, if the frequency that terminal sends is differed with audio range frequency residing for receiving terminal, goes to step 2, again
Send the radiofrequency signal of a different frequency;If frequency and audio range frequency phase residing for receiving terminal that call terminal sends
Together, receiving terminal is set up and is contacted with call terminal;
Step 5, terminal sound is played by receiving terminal.
Above-mentioned receiving terminal is the terminal with frequency modulation function and with audio playing function such as radio or intercom.
Specifically, press China's standard, radio under the working condition of FM FM signals, the electromagnetic wave signal of reception
It is 88MHz~108MHz.Therefore, the scope for setting the radiofrequency signal that terminal sends also is defined as in the frequency
In the range of, terminal is the modulated signal for being loaded with characteristic sounds to the signal that receiving terminal sends.If receiving terminal is right
Say machine, the frequency range of intercom is general to be concentrated between 136~470MHz, therefore, the radiofrequency signal that terminal sends
Scope should be also determined in the range of this.When terminal receives the instruction for taking receiving terminal channel, start from low frequency
Rate sends radiofrequency signal to high-frequency.If such as terminal is mobile phone, when mobile phone has incoming call call, broadcasting music etc.
Situation can be as the instruction for taking receiving terminal channel;When for example terminal is navigator again, navigator is initially entered
Navigation pattern can be as the instruction for taking receiving terminal channel.When terminal launches a radiofrequency signal each time, connect
Receiving end receives the radiofrequency signal, starts to judge the frequency of the frequency with channel wave band residing for receiving terminal of the radiofrequency signal
It is whether consistent.If consistent, that sets up between terminal and receiving terminal contacts, and receiving terminal plays this feature sound,
Voice-grade channel in receiving terminal is to open-destination, there is provided to the passage that terminal is exported as terminal audio frequency.If frequency
Inconsistent, terminal sends the radiofrequency signal of next frequency.In the case of frequency is consistent, terminal sends loading sound
The radiofrequency signal of message number is played in after receiving terminal, receiving terminal demodulation.
Described matching process can not possibly be carried out the unconfined time in step 3, therefore set a week time
Phase, when the time cycle is exceeded in matching process, judge that matching is unsuccessful.
For step 2, terminal transmission radiofrequency signal is carried out according to certain order.User sets in terminal in advance
Put radio frequency signal frequency scope, such as 88MHz~108MHz;Then terminal according to low frequency to high-frequency
Order successively transmission signal in receiving terminal.During transmission signal, in addition in accordance with the above-mentioned time cycle,
Difference on the frequency between the adjacent signals of terminal transmission is a fixed value, such as 0.1MHz.
One kind for step 2 is improved, and before terminal transmission radiofrequency signal, user can listen extensively according to oneself
The custom broadcast pre-sets several wave bands, and terminal preferentially sends the frequency signal for pre-setting, if these signals do not have
Have that the match is successful, radiofrequency signal is being sent successively to high-frequency according to low frequency.
In order to realize the above method, the present invention also provides a kind of device, the device include radiofrequency signal module 1,
Frequency error factor module 2, signal emission module 3, signal receiving module 4, frequency matching module 5.
With reference to Fig. 2, the radiofrequency signal module 1, frequency error factor module 2, signal emission module 3 are arranged at
In terminal, signal receiving module 4, frequency matching module 5 are arranged in receiving terminal.The radiofrequency signal module
1 is used to produce radiofrequency signal;The frequency error factor module 2 is used to drive radiofrequency signal module 1 to produce different frequencies
The radiofrequency signal of rate;The signal emission module 3 is used to launch radiofrequency signal;The signal receiving module 4
For receiving radiofrequency signal;The frequency matching module 5 is used to judge the frequency of radiofrequency signal.
With reference to Fig. 3, the device also includes clock unit 6, for receiving terminal provides clock reference signal, if one
Frequency matching module 5 fails that the match is successful in cycle, then the frequency error factor module 2 for sending a signal to terminal switches
Next frequency.
In order to realize that the device sends a certain frequency RF signal in sequence or preferentially, can add in the apparatus
Plus input module 7, the input module 7 include both of which:The input of pattern one can trigger the device according to
One permanent order and difference on the frequency and time difference send radiofrequency signal;The input of pattern two can send out the assembly first
After giving the signal of some special frequencies for setting radiofrequency signal is sent according still further to the mode of pattern one.
With reference to Fig. 4, Fig. 5, based on above-mentioned input module 7, it includes the of input radio frequency signal frequency range
One module 7-1, the second module 7-2 of input adjacent radio frequency signal frequency difference;Three above module combines remaining
Module completes the working method of pattern one jointly.The input module 7 also includes the of input set specific frequency signal
Four module 7-4;4th module 7-4 completes the working method of pattern two with remaining module jointly.
As a modification of the present invention, multiple difference on the frequencies can be set, when having traveled through one to set frequency range
After, frequency is not matched, go to next difference on the frequency and re-start matching.
