Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
With reference to Fig. 1, Fig. 1 is a kind of flow diagram of engine data acquisition method provided in an embodiment of the present invention；Institute
Stating engine data acquisition method includes：
S10：Obtain constant transmissions period and the acquisition time interval of engine data；
Specifically, the constant transmissions period of the engine data is that the fixed of XCP/CCP synchronous data transmission mode passes
Defeated period, for example, 10ms or 100ms, but the constant transmissions period be cannot adjust or be continuously 10ms progress
Data, which are transmitted or are continuously 100ms, to be carried out data transmission.
In order to meet in real data collection process to the needs in different acquisition period, the acquisition time interval ginseng is introduced
Number, the acquisition methods at the acquisition time interval are specially：
Obtain the constant transmissions period and collection period；
According to the collection period and the constant transmissions period, the acquisition time interval is obtained.
Specifically, the collection period is the real data collection period of setting, such as collection period is 1000ms, fixed to pass
The defeated period is 10ms, then acquisition time interval is just 100.
That is, being just acquired to the engine data that the constant transmissions period for going to the 100th time is transmitted.
S11：Data are sent to engine controller and send instruction, to control the engine controller according to the fixation
Transmission cycle sends the engine data；
S12：When receiving the first packet engine data, judgement receive the engine data number whether
More than or equal to the acquisition time interval；
Specifically, when receiving the first packet engine data, to receive the number of the engine data into
Row counts, and whether the number that judgement receives the engine data is greater than or equal to the acquisition time interval.
The number for receiving the engine data is expressed as the fixed biography that engine sends the engine data
The number in defeated period.
S13：If so, the engine data being currently received is stored, and docking receives the hair again
The number of motivation data is counted.
Specifically, for example, being divided between acquisition time 5 times, then the 5th constant transmissions periodic transfer of engine is started
Machine data are stored, and after the completion of storage, are counted to the number for receiving the engine data, are persistently followed again
Ring.
As can be seen from the above description, even if engine controller carries out engine data transmission according to the constant transmissions period,
But the engine data acquisition method passes through flexible setting collection period, only when the number for receiving engine data meets
Acquisition time interval, such as at five times, the 5th received engine data is stored, preceding engine number received several times
According to without storage.And then the adjustable of data collection cycle is realized indirectly, improve the flexibility of data acquisition.
Based on the above embodiment of the present invention, in an alternative embodiment of the invention, mentioned with reference to Fig. 2, Fig. 2 for the embodiment of the present invention
Another flow diagram of the engine data acquisition method of confession；The engine data acquisition method further includes：
S14：If it is not, then abandoning the engine data being currently received, and return step S12；
Specifically, the engine data is persistently received, until the number for receiving the engine data is greater than or waits
In the acquisition time interval.
Specifically, for example, being divided between acquisition time 5 times, then the 1-4 constant transmissions period of engine controller is passed
Defeated engine data abandons, and the engine data is persistently received, by the 5th constant transmissions periodic transfer of engine controller
Engine data stored, after the completion of storage, the number for receiving the engine data is counted again, is held
Continuous circulation.
It should be noted that needing the engine data of storage being uploaded to cloud platform after the completion of data storage, refer to
Fig. 3, Fig. 3 are the flow diagram that engine data provided in an embodiment of the present invention uploads cloud platform, particularly spread journey such as
Under：
S20：Judge whether the engine data of upload in need；
Specifically, the upload period due to engine data is not defined, to upload state in real time, work as acquisition time
Between when being divided into 5, then there will be no the engine datas that needs upload, therefore are uploading within first constant transmissions period
When engine data, need to judge whether the engine data of upload in need.
S21：If so, obtaining the engine data, and execute step S22；
It should be noted that if no, then return step S20.
S22：Judge whether data transfer communications are in normal operating conditions；
S23：If so, uploading engine data to cloud platform, and execute step S24；
It should be noted that if no, then return step S22.
S24：Judge whether the engine data sends success；
Specifically, due in engine data transmission process, it may appear that the case where going offline, it is therefore desirable to engine number
According to whether sending and successfully judged；
S25：If so, judging whether the engine data uploads completion；If it is not, then return step S22, again on
It passes；
S26：If so, return step S20；
Specifically, return step S20 starts to transmit next bag engine data after the completion of a bag data uploads, continue
Circulation completes the upload to engine data to cloud platform.
It should be noted that if no, then return step S21, i.e., persistently obtain present engine data and uploaded.
Based on the above-mentioned whole embodiments of the present invention, a kind of engine data is additionally provided in an alternative embodiment of the invention and is adopted
