Step S104: if not, sending incremental data corresponding with current state mark.
In specific implementation, when slave judge the data acquisition being currently received instruction in current state mark with it is upper
Historic state mark in the secondary data acquisition instruction received is different, illustrates incremental data and history shape that host needs to obtain
State identifies corresponding incremental data difference, represents the incremental data transmission success of last time transmission, then slave sends current state mark
Know corresponding incremental data.Further, the incremental data that slave can send the last time is deleted, so that memory space is saved,
It can also preferably avoid sending and make mistakes.
In one embodiment, incremental data is specially encrypted data.When slave sends incremental data to host, first
Data are subjected to cryptographic operation, prevent data to be tampered with this, safety is higher.It should be noted that the specific method of encryption
The present invention is not construed as limiting, as long as host and slave are using adaptable encryption method and decryption method.In addition, in other realities
It applies in example, in order to improve the efficiency of transmission, incremental data can also be compressed, corresponding, host is also needed according to increment

Identical, the status indicator of different incremental datas is different；
Step S202: data acquisition instruction is sent to slave.
In specific implementation, host needs to generate data acquisition and instructs and be sent to slave when obtaining incremental data.Number
According to including status indicator in acquisition instruction, wherein when the incremental data of acquisition and last time obtain it is identical when, by status indicator
It is set as identical as the status indicator of last time；When the incremental data of acquisition and the difference of last time acquisition, data acquisition is instructed
In status indicator be set as different from the status indicator of last time.It should be understood that when host receives incremental data not successfully,
Then send again and identify identical data acquisition with last state and instruct, make slave tell host occur in last time transmission it is different
Often, need to retransmit the incremental data of last time；When host has successfully received incremental data, then send with last state mark not
Same data acquisition instruction, makes slave tell host last time transmission success, need to send new incremental data.For example, host is sent out
Sending includes that the data acquisition of status indicator X is instructed to slave, after slave receives the instruction, sends incremental data accordingly
To host；If host receives incremental data, transmission includes that the data acquisition of status indicator Y is instructed to slave, slave root
It is judged that status indicator Y is different from status indicator X, it is known that last time incremental data is sent successfully, then is sent next increment data
To host；If host does not receive incremental data, the data acquisition instruction that transmission includes status indicator X is repeated, slave connects
After receiving known to last time incremental data transmission failure, then again send with status indicator X relative to incremental data.
A kind of incremental data transmission method provided by the present invention, host send data acquisition instruction in include shape
State mark, the status indicator for obtaining equal increments data is identical, and the status indicator for obtaining different incremental datas is different.Keep slave logical
In the data acquisition instruction that the current state mark crossed in the data acquisition instruction that judgement is currently received was received with last time
Historic state identify whether it is identical, so that it is determined that out the incremental data of last time whether transmission success；Think if different transmission at
Function, slave send current state and identify corresponding incremental data, avoid due to not knowing whether last incremental data is sent out
It repeats to send caused by sending successfully；Transmission failure is then thought if they are the same, and historic state is identified corresponding incremental data weight by slave
It is new to send, the transmission problem for successfully avoiding loss of data is sent until confirming.It can be seen that the present invention passes through data acquisition
Status indicator in instruction can accurately judge incremental data whether transmission success, corresponding processing is then made, to keep away
The data transmission problems for having exempted from loss of data or Data duplication reduce the error rate in incremental data transmission process, ensure that
Safety in incremental data transmission process.

Step S301: host generation includes the data acquisition instruction of status indicator, wherein the state of equal increments data
Identify identical, the status indicator difference of different incremental datas.
Step S302: data acquisition instruction is sent to slave by host.
The slave mentioned in the present embodiment can be the instrumentation devices for measurement, and host can be upper to communicate with slave
Position machine, it is generally the case that the communication mode of host and slave is wire communication.Certainly, those skilled in the art can be according to reality
Situation uses wire communication, and the present invention is not construed as limiting.
Specifically, host needs to generate data acquisition and instructs and be sent to slave when obtaining incremental data.Data acquisition
It include status indicator in instruction, wherein when the incremental data of acquisition is identical as last time, set status indicator to and last time
Status indicator it is identical；When the incremental data of acquisition and when last time difference, by data acquisition instruct in status indicator be set as
It is different from the status indicator of last time.It should be understood that then being sent and last time shape again when host receives incremental data not successfully
State identifies identical data acquisition instruction, so that slave is told host and exception occurs in last time transmission, needs in retransmission
The incremental data of secondary transmission；When host has successfully received incremental data, then sends and identify different data acquisitions from last state
Instruction, makes slave tell host last time transmission success, need to send new incremental data.
Step S303: slave receives data acquisition instruction, and judges current in the data acquisition being currently received instruction
The historic state in data acquisition instruction that status indicator and last time receive identify whether it is identical, if so, send again with
Historic state identifies corresponding incremental data, if not, sending incremental data corresponding with current state mark.
Specifically, slave can determine whether host succeeds according to the status indicator in the data acquisition instruction received
Receive an incremental data.After slave receives data acquisition instruction, status indicator therein is obtained first, judgement is worked as
Before historic state in the data acquisition instruction that receives with last time of current state mark in the data acquisition instruction that receives
Identify whether it is identical, if the same illustrate host be not received by slave last time transmission incremental data, last time data transmission
Failure needs to obtain the incremental data of last time transmission again.If current status indicator and the last status indicator obtained
Difference then illustrates that host needs to obtain the incremental data different from the incremental data that last time obtains, that is, can be regarded as the increasing of last time
Measure data transmission success.
It is to be appreciated that the data acquisition instruction being currently received can be to refer to for obtaining the reading of new incremental data
It enables, can also be the stressed instruction of the incremental data due to last time unsuccessful transmission, for obtaining last transmission.It needs to illustrate
It is that the data acquisition instruction received the last time mentioned in the present embodiment refers to the number that receives nearest with current time interval
According to acquisition instruction；The current state mark mentioned in the present embodiment and the state that historic state mark is in data acquisition instruction
Mark is only to distinguish herein.
