Description of the drawings
Fig. 1 show the work flow diagram of the main side of a preferred embodiment of the invention.
Fig. 2 is shown in Fig. 1 embodiments from the work flow diagram at end.
It is the communication connection statistical form of embodiment illustrated in fig. 1 shown in Fig. 3.
Specific embodiment
The specific embodiment further illustrated the present invention with reference to a specific embodiment.It is provided by the invention wireless
Communicate frequency-hopping method, for re-establishing connection after communication outages, belongs to a kind of passive type frequency-hopping method, i.e. communication outages
Frequency hopping stops frequency hopping after communication connection.The present embodiment includes a main side and one from end, and the present invention also includes multiple main sides
With one from end, a main side and multiple from end or multiple main sides and multiple embodiments from end.
It is the work flow diagram that connection is re-established after main and slave terminal breaks respectively as depicted in figs. 1 and 2.In this implementation
In example, wireless frequency-hopping method step according to the present invention is as follows：
First, 8 wireless frequency points are preset.Wireless frequency point in the present embodiment belongs to 2.4G frequency ranges, specific to be respectively：
2414.5MHz,2419.5MHz,2424.5MHz,2429.5MHz,2434.5MHz,2439.5MHz,2444.5MHz,
2449.5MHz。
As it can be seen that being divided into fixed 5MHz between each frequency point, selected foundation is：With leading to for existing Bluetooth and WIFI
Frequency point is believed to be utmostly staggered.The frequency range 2402MHz-2480MHz of Bluetooth, using AFH (Adaptive
Frequency Hopping) technology, frequency point is integer MHz, between each frequency hopping point between be divided into 1MHz；The communication frequency of WiFi
Point 2412MHz, 2417MHz, 2422MHz, 2427MHz, 2432MHz, 2437MHz, 2442MHz, 2447MHz, 2452MHz,
2457MHz、2462MHz、2467MHz、2472MHz、2484MHz.It can be seen that the whole in the present embodiment preset wireless frequency point with
Existing communication frequency point is staggered.Obviously, there can also be the predetermined manner of other a variety of wireless frequency points, include other default numbers its
He is wireless frequency point or frequency point interval.
2nd, main side current frequency point broken string after, as shown in Figure 1, current frequency point or leap to another frequency point send out it is pre-
Determine formatted data, be in this example instruction of shaking hands, if received within predetermined time T1=1.8 millisecond from end returned data
It responds, then main side stops frequency hopping, and reconnection success, whereas if main side is not received from end returned data, then main side is not receiving
The number record N of response increases by 1 time.In the present embodiment, from main side send out predetermined format data to determine whether complete once connect
The process of receipts takes about 3 milliseconds (chip of use is different, this data may be different).Then repetition above-mentioned transmission in main side is held
Finger enables, and receives the process from end returned data.When the number that main side does not receive response records N=8, i.e., main side repeats above-mentioned
During transmitting and receiving process 8 times, if do not received yet from end returned data, after T2=25 milliseconds of main side suspend mode first time, skip to
Another frequency continues to send instruction of shaking hands, and will not receive response number record and be initialized as 0.
It can be seen that the time interval that the present embodiment main side skips to next frequency from current frequency is about 50 milliseconds.Main side suspend mode
The purpose of one time T2=25 millisecond is to reduce power consumption, reduces frequency interferences and the possibility of conflict, improve system possibility.
3rd, the work flow diagram from end being illustrated in figure 2 in the present embodiment.When finding to be in broken string state from end,
Reconnection starts.The predetermined format data that send out of main side, such as instruction of shaking hands are received from continued access is supported, if in a listening period
It is interior, for 5ms in the present embodiment, the instruction of shaking hands that main side sends out is received from end, then is maintained at current frequency point and communicates with main side, instead
It, does not receive predetermined format data in a listening period from end, another wireless frequency point is immediately jumped to from end.
Wherein, the frequency point sequence of the frequency hopping of main and slave terminal is to determine, can ensure that main and slave terminal can be covered in this way
The whole frequency points of lid, and ensure that the reconnection probability of each frequency point is consistent, so as to ensure consistency of the system in different frequent points.
Further, in the present embodiment, the frequency hopping of main and slave terminal is using sequence frequency-hopping mode, i.e., if current frequency point leads to
Believe unsuccessful, then jump to next adjacent wireless frequency point, if current wireless frequency point has been the last one wireless frequency point,
Initial first wireless frequency point is jumped to, this sequence is fairly simple.If certain main side frequency hopping using sequence frequency-hopping mode and from
End is also allowed using reverse sequence frequency-hopping mode.Only the frequency point sequence of guaranteed frequency hopping is to determine, and can be covered all
Predetermined frequency point.
Further, the predetermined format data that main side is sent in this implementation are instruction of shaking hands.
The present invention also provides a kind of main side using above-mentioned wireless communication frequency-hopping method or from end.
It is the communication connection statistical form of the present embodiment as shown in Figure 3 below by table detailed analysis this example.For
For the sake of intuitive, each frequency point is numbered, and with number reference frequency point, it is to be understood that when main and slave terminal is same
When identical frequency point is in one period, the communication of main and slave terminal could reconnection success.As shown in figure 3, wherein boldface letter is located at
Main side sends two boundary times of starting and ending for instruction of shaking hands, and is 50% with passing through the successful possibility of reconnection from end,
And dash area, main and slave terminal centainly can reconnection success, therefore the successful possibility of its reconnection be 100%.It is listed in table
Main side handles all 8 kind possibility of current frequency point.As can be seen that in 400 milliseconds, it is current no matter which kind of main side is in
Frequency point, main and slave terminal reconnection can successfully have the possibility of 3 times 100% and 2 times 50%, add up to successful connection 4 times.I.e. every time
The theoretical used time successfully linked up is 100 milliseconds, in the embodiment reconnection used time greatly improve compared with prior art.If into one
Step shortens main side dormancy time, and the reconnection used time can further reduce, and corresponding power consumption can increased, people in the art
Member can need to select suitable dormancy time, reconnection number, frequency and number of frequencies etc. according to application.
Wireless communication frequency-hopping method provided in this embodiment is simple, efficient, reliability is high, and the wireless frequency point of use is existing logical
Letter frequency point is staggered, it is possible to prevente effectively from outside electromagnetic interference；In addition main side introduces dormancy mechanism in the present embodiment, avoids cover more
Identical equipment is simultaneously using generation conflict, while power consumption can be saved.
It is clear that a kind of specific embodiment that above-described embodiment is illustrative of the invention, and be not specific to its
The limitation of feature, those skilled in the art in the case where not departing from disclosure range, can also make a variety of changes
And modification, therefore the range disclosed herein that should also belong to of the lower deformation of with good grounds present invention enlightenment or equivalent program, it is of the invention
Protection domain should be defined by the claims.
