Problems solved by technology

[0002] Because alarm fault analysis requires high-frequency historical data, but the frequency of historical real-time data uploaded to the platform cannot meet the needs of fault alarm analysis. If the frequency of uploading real-time information is increased, the traffic consumption will be large, and for the fault analysis requirements, no faults will occur A large amount of historical data uploaded from time to time is redundant. This patent proposes to save high-frequency real-time data to the SD card, and to process redundant data in a timely manner, and reissue effective historical data when a failure occurs.

Embodiment 2

[0036] like figure 2 Shown, a kind of SD card redundant data processing method based on alarm function of the present invention comprises the following steps:

[0037] Step 1: Initialize, counter i=0, create a driving cycle file, and save the data in real time;

[0038] Step 2: Judging whether it is a new driving cycle, if it is, the counter i+1, then proceed to the next judgment, otherwise, there is no need to create a new file, and continue to save real-time information.

[0039] Step 3: Determine whether there is an alarm message. If there is an alarm message, determine whether the driving cycle counter is greater than five. If it is greater than five, only keep the five driving cycles before the fault occurrence point, delete the previous driving cycle information, and perform fault Analysis, if the driving cycle counter i<5, then keep all the data and perform fault analysis; if there is no alarm information, then judge whether the current driving cycle counter i is grea...

Abstract

The invention relates to the field of Internet of Vehicles, in particular to an SD card redundant data processing method based on an alarm function. The method comprises the steps of judging whether alarm information exists or not in real time, when the alarm information exists, driving cycles before M pieces of driving cycle data of the alarm information are deleted, reserving M nearest driving cycle data, and if the number of the driving cycles is smaller than M, reserving all the data, and uploading the reserved data to a cloud platform after fault backup; and when the stored driving cycleexceeds N, deleting the driving cycle before the M driving cycles. The function of storing real-time data in the research and development process can be met, redundant data can be deleted to relieve the storage pressure of an SD card, and it can be guaranteed that effective data is obtained for analysis during alarming.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to an SD card redundant data processing method based on an alarm function. Background technique [0002] Because alarm fault analysis requires high-frequency historical data, but the frequency of historical real-time data uploaded to the platform cannot meet the needs of fault alarm analysis. If the frequency of uploading real-time information is increased, the traffic consumption will be large, and for the fault analysis requirements, no faults will occur A large amount of historical data uploaded from time to time is redundant. This patent proposes to save high-frequency real-time data to the SD card, and process redundant data in time, and reissue effective historical data when a failure occurs. Contents of the invention [0003] The embodiment of the present invention provides an SD card redundant data processing method based on the alarm function, which can meet the functi...
