Specific embodiment
It due to SD card limited storage space, needs to delete redundant data in time, but alarms and need to analyze again when occurring to go through
History data, this patent propose data delete with backup method as shown in Figure 1, SD card store real time data during, often
One driving cycle creates a file, and every ten driving cycles are one and judge the period: when alarming, before retaining alarm
The historical data of five driving cycles, and reissue to platform, remainder data is considered as redundant data and is deleted；If alarm free, protect
Five driving cycle data after staying, first five driving cycle data is deleted.Guarantee to alarm by above scheme
When can reissue effective data and reduce flow waste and can guarantee that SD card possesses enough memory spaces.
As shown in Figure 1, the present invention provides a kind of SD card redundant data processing method based on warning function, comprising:
Real-time judge whether there is warning message,
When there are warning message, the driving cycle before M driving cycle data of warning message is deleted, nearest M is retained
A driving cycle data, and if driving cycle less than M when, retain all data, will reservation data fault back up after upload
To cloud platform；
When the driving cycle of storage is more than N, the driving cycle before M driving cycle is deleted.
Preferably, when the interval of fault message twice is less than M, the driving cycle data at the interval of fault message are uploaded
To cloud platform.In this way, the problem of repetition uploads can be effectively reduced, flow loss is reduced.
Preferably, M can be 3-6, it is preferred that can be 5, N can be 7-12, it is preferred that can be 10.
Embodiment two
As shown in Fig. 2, a kind of SD card redundant data processing method based on warning function of the present invention, comprising the following steps:
Step 1: initialization, counter i=0 creates a driving cycle file, and saves data in real time；
Step 2: judging whether is new driving cycle, if it is counter i+1, then carry out next step judgement, otherwise, nothing
New files are needed, continue to save real time information.
Step 3: judging whether there is warning message, whether driving cycle counter is then judged if there is warning message
Greater than five, first five driving cycle of point occurs if it is greater than five items retention faults, driving cycle information deletion before,
And accident analysis is carried out, if driving cycle counter i < 5, retains all data and carry out accident analysis；If do not deposited
In warning message, then judge whether current driving cycle counter i is greater than 10, if continuing to save real time data no more than 10,
Otherwise, retain last five driving cycle information to delete remaining driving cycle data.
It reissues step 4: carrying out failover backup data to platform, terminates after the completion of reissuing.
SD card real-time data memory carries out as procedure described above, until failover backup data reissue completion.
As shown in figure 3, a kind of SD card redundant data processing system based on warning function, including fault detection module, follow
Ring determination module, cloud platform,
