Embodiment two
Shown in reference picture 2, Fig. 2 shows a kind of low power loss communication node two provided in an embodiment of the present invention
The another kind of secondary wake/sleep method realizes flow, for the ease of description, illustrate only and implements with the present invention
The related part of example.Specifically, the secondary wake/sleep method of the low power loss communication node, including following step
Suddenly：
The wake-up period of S201, Section Point in current awake/dormancy period receives first node transmission
Predetermined length packet in n-th wake-up chip segment, n is positive integer, and the packet includes
Wake up code and positioned at the communication data for waking up code end, the wake-up code includes the m continuous wake-up
Chip segment, m is positive integer.
That is, waking up the different existing skill of code in the packet that sends to Section Point of first node
Intraoperative waken-up code, in the present invention, the wake-up code that first node sends is to wake up chip segment by multiple is continuous
Composition, Section Point can receive any one and wake up chip segment, and it is whole complete no longer to receive one
Wake-up code.And multiple continuous chip segments that wake up sequentially are continuously transmitted when sending, i.e., from the 1st
Individual wake-up chip segment starts to send, until after last wake-up chip segment is sent completely, then sending logical
Letter data.For example：Waking up code includes that 10 wake up chip segment (i.e. during m=10), are followed successively by the 1st
Chip segment, the 2nd wake-up chip segment, the 10th wake-up chip segment of the 3rd wake-up chip segment ... are waken up,
First node sends when sending waking up chip segment since the 1st, until the 10th wake-up chip segment
Communication data is retransmited after being sent completely.
It is two nodes in wireless network due to first node and Section Point, and two nodes are all
Work is periodically waken up, the wakeup time point of Section Point is with the wakeup time point of first node not necessarily
It is synchronous, therefore, may when wakeup time point wakes up Section Point within a wake/sleep cycle
It not is the 1st wake-up chip segment to receive, such as when the Section Point wakes up, first node sends
The 3rd wake up fragment reach, then Section Point can receive the 3rd wake-up chip segment.
Each described transmission time length t for waking up chip segment is equal, and in each described wake-up chip segment
Fragment Count is carried, the continuous Fragment Count for waking up chip segment is continuous natural number, and institute
The minimum value for stating Fragment Count is 0 or 1.
It should be noted that the transmission time length for waking up chip segment refers to that first node is sent completely one
Time required for waking up chip segment.Fragment Count is to indicate the wake-up chip segment continuous multiple
The position in chip segment is waken up, and then front and rear each how many wake-up code of the wake-up chip segment conveniently judged
Fragment.
That is, each length for waking up chip segment is equal, and multiple continuous wake-up chip segments
It is continuous counter, the quantity for for example waking up chip segment is 10, the 1st wakes up chip segment to the 10th
Wake up chip segment distinguishing corresponding Fragment Count can be 1,2,3 ... 10 etc..
S202, the Fragment Count a and the transmission time length obtained in n-th wake-up chip segment
t.Specifically, after Section Point receives n-th wake-up chip segment, you can obtained from fragment is waken up
Its Fragment Count a for carrying, and transmission time length can be predetermined set, such as one wake-up code
The conveying length of fragment is 100 milliseconds.
S203, the Fragment Count a waken up in chip segment according to described n-th are extrapolated in the wake-up code
The quantity x of the wake-up chip segment not sent also, then the quantity x is done into multiplication with the time span t
Computing obtain current time apart from the communication data reach when required time interval Δ T.
Because each wake-up chip segment is continuous counter, therefore, when n-th wake-up code for knowing reception
During Fragment Count a in fragment, it is possible to know the quantity x of the wake-up chip segment not sent also.And call out
Awake chip segment is sequentially continuously transmitted, and, each wakes up equal during the transmission time length of chip segment
, so, when the quantity x of the wake-up chip segment that will do not sent also is multiplied by the transmission that each wakes up chip segment
Between length can just obtain sending it is follow-up wake up chip segment required for time.Because first node has sent
Begin to send communication data after follow-up wake-up chip segment, so, send follow-up wake-up chip segment
Time interval Δ T required when reaching of required time i.e. current time range communication data.
That is, when Section Point wake-up after, receive one wake up chip segment after, just no longer
The follow-up wake-up chip segment of reception, but the Fragment Count meter in the wake-up chip segment for receiving
Calculate the communication data in packet also needs to how long can be only achieved.
It should be noted that according to described n-th wake up chip segment in Fragment Count a extrapolate described in
The quantity x of the wake-up chip segment not sent also in code is waken up, with specific reference to multiple continuous wake-up codes
The Fragment Count mode of fragment is different and different, for example：
In an embodiment of the invention, multiple continuous Fragment Counts for waking up chip segment increase successively
Greatly, it is corresponding, wake up the Fragment Count a in chip segment according to described n-th and extrapolate what is do not sent also
The step of quantity m for waking up chip segment, is specially：
The total number m and the Fragment Count a of the wake-up chip segment are done into subtraction and obtains described going back
The quantity x of the wake-up chip segment not sent.
If that is, it is multiple continuous wake up chip segment Fragment Count be since 0 or 1 successively
Incremental count, then the total quantity for waking up chip segment is subtracted the fragment meter waken up in chip segment for receiving
Number can obtain the quantity of the wake-up chip segment not sent also also.
For example during m=10, and the minimum value of Fragment Count is 1, then multiple continuous wake-up chips
The Fragment Count of section is followed successively by 1,2,3 ... 10.Assuming that the wake-up chip segment that Section Point is received is the 3rd
Individual wake-up chip segment, then the 3rd Fragment Count waken up in chip segment is also 3, and 3 are subtracted by 10
The quantity of the wake-up chip segment not sent is 7.
For example during m=10, and the minimum value of Fragment Count is 0, then multiple continuous wake-up chips
The Fragment Count of section is followed successively by 0,1,2 ... 9.Assuming that the wake-up chip segment that Section Point is received is the 3rd
Individual wake-up chip segment, then the 3rd Fragment Count waken up in chip segment is also 2, and 2 are subtracted by 9
The quantity of the wake-up chip segment not sent is 7.
In another embodiment of the present invention, multiple continuous Fragment Counts for waking up chip segments according to
Secondary reduction, and minimum value is 0.It is corresponding, according to the Fragment Count a in described n-th wake-up chip segment
The step of quantity x for extrapolating the wake-up chip segment not sent also, is specially：
The Fragment Count a is defined as the quantity x of the wake-up chip segment not sent also.
That is, in the case, Fragment Count a and calling out for not sending also in the wake-up chip segment
The quantity x of awake chip segment is equal.
For example during m=10, then multiple continuous Fragment Counts for waking up chip segments be followed successively by 9,8,
7……0.Assuming that the wake-up chip segment that Section Point is received is the 3rd wake-up chip segment, then call out for the 3rd
Fragment Count in awake chip segment is also 7, then the quantity of the wake-up chip segment not sent is 7.
In yet another embodiment of the present invention, multiple continuous Fragment Counts for waking up chip segments according to
Secondary reduction, and minimum value is 1；It is corresponding, according to the Fragment Count a in described n-th wake-up chip segment
The step of quantity x for extrapolating the wake-up chip segment not sent also, is specially：
The Fragment Count a is subtracted into the 1 quantity x for obtaining the wake-up chip segment not sent also.
For example during m=10, then multiple continuous Fragment Counts for waking up chip segments be followed successively by 10,9,
8、7……1.Assuming that the wake-up chip segment that Section Point is received is the 3rd wake-up chip segment, then the 3rd
Fragment Count in individual wake-up chip segment is also 8, and the 1 wake-up code that can not sent is subtracted by 8
The quantity of fragment is 7.
S204, Section Point with current time be a dormancy time point, with the time interval as once
The dormancy that dormancy time length enters in the current awake/dormancy period.
After the n-th wake-up chip segment received due to Section Point, first node also may proceed to send
Follow-up is the wake-up chip segment being sent completely, and if Section Point continues to follow-up wake-up chip segment,
Then necessarily causing Section Point will for a long time be in reception state, and then increase power consumption.Therefore, the step
In rapid S204, in the wake-up chip segment that Section Point is received, and calculate communication data and reach
After the time interval Δ T of Shi Suoxu, i.e., into a dormancy in current awake/dormancy period.And should
Time span for dormancy is just that first node continues to send and wakes up follow-up after chip segment for n-th
Time required for waking up chip segment, in this way, accurate after first node has sent follow-up wake-up chip segment
When preparation send communication data, just a dormancy terminates and wakes up Section Point, this time wakes up and is properly termed as
Secondary wake-up.
S205, at the end of a dormancy, wake up and receive the communication number for just reaching immediately
According to, and gone successively to after the communication data has been received secondary in the current awake/dormancy period
Dormancy, until the wakeup time point in next wake/sleep cycle wakes up again when reaching.
