When, matcher can be entered.Second consistent for the messaging parameter of 12 script of signal receiver 11 and sender unit, but makes
When user asks to start matcher to change pairing parameter, matcher can be entered.However, (the step in the second situation
S211), if user does not require to start matcher, S210 can be entered step and terminate by wirelessly communicating the flow of pairing.Work as nothing
After the flow of line communication partner enters step the startup matcher of S207, according to step S208, host apparatus 10 will produce pair
It should be in the wireless communication parameters after at least one pairing that user sets.However, it has been observed that host apparatus 10 can also utilize
Application program launching matcher, therefore the wireless communication parameters after at least one pairing can also be automatic using application program
It generates.Wireless communication parameters after pairing can be the radio frequency identification parameter after pairing, connection golden key, advanced encryption standard gold
Key, serial number or radio channel parameter etc..Then, according to step S209, host apparatus 10 can be by the nothing after at least one pairing
Line messaging parameter stores the second storage device 18 to the first storage device 15 of signal receiver 11 and sender unit 12
In, and complete pairing according to step S210.Therefore, after completing to match, due in signal receiver 11 and sender unit 12
The wireless communication parameters after pairing are stored, user sends in can directly initiate signal receiver 11 and signal later
The wireless communication function of device 12 and carry out wireless data transmission.Also, in step S201 to step S211, due to host apparatus
The step of 10 detection signal receivers 11 and sender unit 12, host apparatus 10 recognize at least one first wireless communication parameters
And the step of at least one second wireless communication parameters, host apparatus 10, generate at least one the matching for corresponding to user's setting
The step of wireless communication parameters to after, is completed using wired data transmission, and any wireless signal can't be broadcasted.
Therefore, the probability that wireless communication parameters are stolen can be greatly reduced in wireless communication pair system 100.
Fig. 3 is wireless communication pair system 100, executes the flow chart of path setting.Fig. 4 be path setting flow in,
By the schematic diagram for selecting selected radio channel in multiple available wireless channels.In this explanation, wireless communication of the invention is matched
To flow can have only comprising the step S201 described in Fig. 2 to step S211 and wireless communication parameters are greatly reduced are stolen
Probability technique effect.However, being set to optimize the radio channel between signal receiver 11 and sender unit 12
It is fixed.The invention also discloses the flows of path setting.In other words, the flow of the path setting of Fig. 3 can be step S210 it
Subsequent step afterwards.Therefore, after executing the pairing flow of Fig. 2 and the flow of the path setting of Fig. 3, signal receiver 11 and letter
The stolen risk of the wireless communication parameters of number transmitter 12 can not only be greatly reduced, signal receiver 11 and sender unit
Path setting between 12 can also be optimized, therefore can promote the quality of wireless communication.The flow of path setting includes step
Rapid S301 to step S306.However, any reasonable step transformation and newly-increased/omission step come under scope of the invention.
Step S301 to step S306 is described in down:
Step S301:The information in multiple available wireless channels between identification signal receiver 11 and sender unit 12;
Step S302:Detect in multiple available wireless channels whether at least one available wireless channel is disturbedIf so, into
Enter step S303;If it is not, entering step S306;
Step S303:Host apparatus 10 starts path setting program, and informs user;
Step S304:User is at least one selected by being selected in multiple available wireless channels by host apparatus 10
Radio channel;
Step S305:Path setting is completed.
Step S306:Whether user asks to start path setting program to set transmission channelIf so, entering step
S303;If it is not, entering step S305 and completing path setting.
In step S301, what host apparatus 10 can be between identification signal receiver 11 and sender unit 12 is multiple available
The information of radio channel (Available Wireless Channel).For example, as shown in figure 4, host apparatus 10 can be distinguished
Know the preset multiple radio channel CH1 to CH4 of script, wherein radio channel between signal receiver 11 and sender unit 12
The corresponding frequency ranges of CH1 are B1, the corresponding frequency ranges of radio channel CH2 are B2, the corresponding frequency ranges of radio channel CH3
It is B4 for B3, the corresponding frequency ranges of radio channel CH4.Since wireless communications environment can cause certain frequency spectrums that channel gain occurs
(Channel Gain) decay, such as shadow effect (Shadow Effect) or with band signal interfere.Therefore for multiple
For radio channel CH1 to CH4, corresponding received signal strength index (the Received Signal in each channel
Strength Indicator, RSSI) information also can be different.Then, in step s 302, host apparatus 10 detects multiple available
Whether at least one available wireless channel is disturbed (Channel Interference) in radio channel.And sense channel is done
The foundation disturbed can be that RSSI information above-mentioned, the news of training signal (Pilot Signals) are miscellaneous than (SNR) or any judgement
Whether the channel gain of radio channel decays the algorithm of (Fading).For example, in Fig. 4, radio channel CH4 occur compared with
The case where interfering greatly, channel gain deep fades and RSSI caused seriously to reduce.At this point, according to step S303, host apparatus
10 can start path setting program, and inform user.Conversely, if multiple radio channels are all no disturbed, according to step
S306, host apparatus 10 will inquire whether user asks to start path setting program to change transmission channelIf so, into
Step S303;If it is not, entering step S305 and completing path setting.In other words, the startup path setting of S303 is entered step
There are two types of the conditions of program.The first is disturbed at least one available wireless channel in multiple available wireless channels, host dress
Path setting program can be started by setting 10.Second is that multiple available wireless channels are not disturbed, but user asks to start
When path setting program, host apparatus 10 can also start path setting program.Later, according to step S304, user passes through master
Machine device 10 in multiple available wireless channels by selecting at least one selected radio channel.For example, as shown in figure 4,
User can be by selecting the radio channel CH2 of an annoyance level minimum in multiple available wireless channel C H1 to CH4.However,
The step of also being rationally changed to any radio channel for having and avoiding and using and be disturbed of step S304.For example, in step
In rapid S304, if multiple available wireless channels, by severe jamming, user can set new radio channel CH5 (such as Fig. 4 institutes
Show), and set its corresponding frequency range B5.Then, user can select new radio channel CH5 as wireless transmission
Signal spectrum range.It is at least one selected after user selects at least one selected radio channel according to step S304
The radio channel selected will be applied to the wireless transmission between signal receiver 11 and sender unit 12, and according to step
S305 terminates path setting program.Therefore, after executing step S301 to step S306, signal receiver 11 and sender unit
12 will not use by the correspondence frequency band progress signal transmission of the radio channel of severe jamming.Even all preset radio channels
When all by severe jamming, user still can be with custom signal transmission bandwidth to avoid received signal strength serious distortion.In other words
It says, the path setting program of step S301 to step S306 ensure that wireless between signal receiver 11 and sender unit 12
Signal transmitting quality, so that the operation between signal receiver 11 and sender unit 12 has higher reliability.
The wireless communication pair system 100 of the present invention, in addition to being sent out signal receiver 11 and signal using host apparatus 10
Device 12 is sent to carry out wireless communication except pairing, in other embodiments, signal receiver 11 and sender unit 12 can also be real
The function of self existing pairing.For example, sender unit 12 can retain an accommodating groove.As signal receiver 11 (USB Dongle)
When putting the accommodating groove of sender unit 12 into, as long as keeping electric power starting, sender unit 12 and signal receiver 11 can
It is connected with built-in wired connection end, and completes self pairing of wireless communication.
In conclusion the present invention describes a kind of wireless communication matching method and its system.Signal receiver and signal
Transmitter is connect by wired connection end with host apparatus.Software/application on host apparatus can obtain signal reception
Device and the relevant paired data of sender unit are simultaneously compared, if identical, then it represents that signal receiver and signal are sent
Device is pairs of, except non-user requires modification pairing parameter, otherwise will not do additional processing.If it is different, software/apply journey
Sequence can actively inquire user make it is no synchronize and match, while operate interface can be also provided, the custom pairing of user is allowed to join
Number, or handled according to the default pairing parameter of system recommendations.Since all pairing steps utilize wire transmission
Data are communicated and are completed, and can't broadcast any wireless signal, host apparatus is considered merely as data transmission during pairing
Medium.Therefore, the probability that wireless communication parameters are stolen can be greatly reduced in wireless communication pair system of the invention.Also,
In order to reduce the disturbed probability of wireless communication, wireless communication matching method of the invention can execute the step of path setting again
