Specific embodiment
Now each aspect of the present invention and example are described.Description below is for comprehensive understanding and illustrates these realities
Example and provide specific details.It will be appreciated by those of skill in the art that even if without these details, it can also be real
Apply the present invention.In addition, some well known structure or functions may be not shown or described in detail, to avoid unnecessary fuzzy phase
It speaks on somebody's behalf bright.
Term used in the description being provided below is intended to wish to explain with its widest rational method, though its with
The detailed description of some embodiments of the invention is used together.Even if certain data may be emphasized below, so
And any term that will be explained in restrictive manner is all to be disclosed and is specifically defined in the part of detailed description.
Fig. 1 is the flow diagram according to an embodiment of the invention without the wireless communications method 100 of matching ID in advance.
In one embodiment, for example, equipment A is mouse or keyboard, and equipment B is softdog.This method can be also used for telecontrolled aircraft,
Intercom system or other any systems that need to match in advance ID.Each equipment is identified by 16 ID.Therefore, in practical application
In, it is insignificant a possibility that a certain working region encounters the product of identical ID.ID is set by fuse or other mechanism
In on the chip of equipment.Only the equipment with identical ID can communicate with one another.The equipment typically operates in industrial scientific medical
(ISM) frequency range has about 100 frequency points.In order to avoid interference, which can choose 16 frequency points as frequency hopping.
In Fig. 1, firstly, being powered (105) to equipment A.Then, equipment A is with certain power (such as the first power or maximum work
Rate) in first passage with several frequency points send signal (110).In one embodiment, which includes the address letter of equipment A
Breath.The address information can be the ID (i.e. first identifier) of equipment A.First power is maximum power.Equipment A is in first passage
Equipment B (i.e. the 2nd ID) most five circulations are searched for, ID (i.e. the 2nd ID) possessed by equipment B is matched with the ID of equipment A
(115).If (120) discovering device B in first passage, equipment A is switched to second channel from first passage, and will include
The message of the ID of equipment A is sent to equipment B (125).Then, equipment A terminates the communication on frequency point.In one embodiment, such as
Fruit does not have discovering device B in first passage, then equipment A is sent matching code on public frequency point with several incremental power and asked
Ask (130).In one embodiment, 100 matching code requests are in public passage with the transmission of respective power.Then, if
There is the ID of equipment disposably to match with the ID of equipment A, then equipment A, which is received, matches code request for one from the equipment
ACK (confirmation character) (135).The number of ACK received from distinct device is compared (140) by equipment A.Judging equipment A is
It is no to obtain the maximum number of ACK from an equipment.If it is, equipment A is switched to third channel (150) from public passage,
In, third channel is the channel for receiving the equipment of the maximum number of ACK.Then, equipment A sends matching code on public frequency point
It wraps to the equipment of the maximum number ACK of transmission, wherein matching code packet includes the ID (155) of equipment A.That is, sending most
The equipment of big figure ACK is equipment B, and being can be with the matched equipment of equipment A.Then, equipment A terminates logical on frequency point
Letter.In another embodiment, if equipment A does not obtain the maximum number of ACK from an equipment, equipment A is powered off one section
Time (170).Hereafter, terminate this method.
In one embodiment, method 100 further includes receiving the message comprising noiseless working frequency points from equipment B, wherein setting
Standby A and equipment B is configured as communicating in working frequency points.
Fig. 2 is the continuity of method 100 shown in Fig. 1.In one embodiment, the code of equipment A and equipment B has been
Match, and equipment A does not power off (205).If equipment A is in second channel there are communication disruption (210) in working frequency points
Or message (215) are transmitted in third channel.Method 100 judges whether equipment A from equipment B receives ACK (220).If it is determined that
It as a result is yes, the then return of this method 100 210.If it is judged that being no, then equipment A retransmission message (225).Method 100
Rejudge whether equipment A from equipment B receives ACK (230).If it is judged that being yes, the then return of this method 100 210.Such as
Fruit judging result be it is no, then equipment A searches for most five circulations (235) of ID of equipment B on several frequency points.Method 100 is sentenced
Whether disconnected equipment A obtains the ID of equipment B.If it is judged that being yes, the then return of this method 100 210.If it is judged that being
No, then equipment A uploads defeated matching code (245) in public frequency point.This method 100 judges whether equipment A receives from equipment B
ACK(250).If it is judged that be it is yes, then equipment A communicates (255) with equipment B.If it is judged that be it is no, then equipment A close
Close a period of time (260).Hereafter, terminate this method.
Fig. 3 is the flow diagram according to another embodiment of the present invention without matching the wireless communications method 300 of ID.It is first
First, equipment B is powered (310).Then, equipment B is waited with public frequency point in second channel or public passage and is received message
(320).If equipment B receives matching code request (330) in public passage, equipment B sends the ID's comprising equipment B
ACK goes back to equipment A (340).Equipment B receives matching code packet (350) from equipment A and stores the ID of equipment A.Then, equipment B with set
Standby A is communicated.If equipment B, which receives matching code request in second channel and sends ACK, goes back to equipment A (360), equipment B
It is switched to first passage from public passage, while terminating the code matches (370) on public frequency point.Then, equipment B is from common frequency
Point is switched to glitch-free working frequency points, into reception pattern (380).Equipment B communicates (390) with equipment A in working frequency points.
Then, this method 300 terminates.
Fig. 4 is the continuity of method 300 shown in Fig. 3.In one embodiment, equipment A and equipment B-code are matched,
And without powering off (410).Then, equipment B selects glitch-free working frequency points and subsequently enters reception pattern (420).If
Equipment B receives message (430) in the second channel, then method 300 judge the ID for including in the message whether the ID with equipment A
Identical (440).If it is judged that be it is yes, then equipment B handles the message (450).If it is judged that being no, then equipment B
Abandon the message (460).Then, method 300 returns to 420.In one embodiment, if equipment B is received in first pipe
Message (470), (for example, equipment A restarts and transmits message by first passage), then equipment B sends the ID's comprising equipment B
ACK goes back to equipment A (480).This method 300 returns to 420.
