Three basic steps of this requirements of process, and be to use serial to queue up under the communication environment of one-to-many
Mode receives with each one by one and clicks on the exchange of row data, and the most not only flow process is loaded down with trivial details, and when carrying out with a bit
When data exchange is hampered for some reason, this point can be rested on and be iteratively repeated said process, so may result in whole
The inefficiency of data exchange process, the efficiency of whole system cannot ensure, energy-conservation low-power consumption is also difficult to.
Summary of the invention
The application provides a kind of method for interchanging data, is specifically related to a kind of clearance-type request of data and data response
Exchange method.This method it is critical only that data requester subsidiary all data in each inquiry request
The data of respondent exchange success or failure information rather than each data respondent are notified independently serially.On the one hand,
Inquiry request is united two into one with response feedback, improves communication efficiency, meet high efficiency demand；Another
Aspect, the data requester time that accurately exchange of notice next round data occurs in inquiry request so that
The data respondent being successfully completed the exchange of this secondary data can calculate the most voluntarily in the exchange of next round data
Before beginning, the dormancy length of oneself, thus meets the demand of energy saving.This method can be used for a little right
In point or point-to-points wired or wireless communication environment.
According to first aspect, the present embodiment provides a kind of data request method, it is characterised in that including:
Start request of data flow process；
Obtain the ID of data respondent；
Sending inquiry request to data respondent, described inquiry request includes: the ID of data respondent, all
The response results mark of data respondent, the time required for request of data next time；
Receive the response data packet of data respondent；
The reception labelling of flag data respondent.
The ID of described data respondent is the address information of data respondent.
Described data respondent is receiving before inquiry request in a dormant state.
According to second aspect, the present embodiment provides a kind of data response method, it is characterised in that including:
Starting data responding process, data respondent terminates resting state；
Receive the inquiry request of data requester；
Resolve data inquiry request；
Judge that the data of described data requester have the most been received and obtained dormancy time；
Enter resting state.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of request-response method in the application one embodiment；
Fig. 2 is the flow chart of request of data in the application one embodiment；
Fig. 3 is the flow chart of data response in the application one embodiment.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is described in further detail.
The term definition used in the application, is explained as follows:
Data exchange: a side sends order or request, and the opposing party gives the communication process of response or response.
Batch (-type) data exchange: periodically or non-periodically repeat the data exchange occurred.
Dormancy: enter low power operation state.
Revive: enter normal power consumption running status.
Efficient: satisfactorily to complete communication process by minimum step and data volume.
Energy-conservation: to be in wake states, after communication completes in a dormant state when communication.
Fig. 1 schematically illustrates the procedure of " request-response " of the present embodiment.Data requester 10
Sending inquiry request to data respondent 11, this inquiry request includes: the ID of data respondent；Total data
The response results mark of respondent；Time required for request of data next time.Data respondent 11 receives
After this inquiry request, changed from resting state, resolve the content of this inquiry request, it is judged that sending of oneself
Response data whether be successfully received, if being received by data requester 10, then continue dormancy: if not counted
Receive according to requestor 10, then continue waiting for, until oneself being queried.
Fig. 2 shows the flow chart of request of data.
Step 21: after request of data flow process starts, data requester is it is first determined whether arrived looking into of a new round
The inquiry time, without arriving query time, then request of data Fang Ze enters waiting state, and enters wait
State, continues thereafter with and judges whether arrive query time and repeat this action；If arrival query time, then
Enter step 22.
Step 22: it is first determined whether the response feedback of all of data respondent is all successfully received, if
All be successfully received, then data query flow process terminates；Without being all successfully received, then data are looked into
Inquiry person can carry out following operation to data respondent: 1. data query person can inquire about next data respondent,
I.e. be not queried the id information of person, described in the id information of the person of being queried be the address information of data respondent；2. exist
After obtaining the address information of this person of being queried, data query person sends inquiry request to this person of being queried；3. quilt
After inquiry receives inquiry request, can be to data query person's feedback response packet.
Step 23: data query person is after receiving the response data packet of feedback, it is judged that whether data respondent
It is properly received the inquiry request of data query person, if data respondent has been properly received data query person's
Inquiry request, then these data respondent is labeled as successfully by data query person；Whereas if data respondent
Be not successfully received the inquiry request of data query person, then these data respondent is labeled as not by data query person
Success.
Step 24: data query person judges that this querying flow is the most overtime, if querying flow is overtime, then
Terminate inquiry；If querying flow has not timed out, then jump to step 22.
Fig. 3 shows the flow chart that data respond.
Step 31: after data responding process starts, first data responder be invoked from resting state, then
Receive the inquiry request that data query person sends.
Step 32: data respondent judges whether to have received inquiry request, without receiving inquiry request,
Then continuing to determine whether it is to receive time-out, if receiving time-out, then entering resting state, a length of system of dormancy
Unite default value set in advance, if not receiving time-out, then jump back to step 31 and continue to inquiry request；
If receiving inquiry request, then first data respondent resolves the inquiry packet of inquiry request, then judges
Whether oneself is query object, if query object, then sends response data feedback, jumps to step 31 and continue
Inquiry request is received in continued access, if not query object, then enters step 33.
Step 33: data respondent judges to be successfully received when the corresponding data oneself sent, if not by
It is properly received, then jumps to step 31 and continue to inquiry request；If be successfully received, then enter step
34。
Step 34: when data respondent is according to the beginning of the acquisition of information next round inquiry request in inquiry request
Between, thus try to achieve data respondent self can be with the time span of dormancy.Data respondent enters dormancy subsequently
State is until whole inquiry response flow process terminates.
