In the present embodiment, when being compiled to onboard system program, a controlling switch, the controlling switch are provided with
Control unlatching/closing loading daily record process；The startup of loading process is forbidden in triggering controlling switch and then triggering；Receive this
After one control instruction, forbid loading daily record process, to reduce I O access, so as to discharge CPU usage.
Forbid loading process to forbid loading the daily record process described in the basis, with reduce the step S2 of I O access it
Afterwards, including：
Step S20, receives the second control instruction；
Step S21, forbids loading process according to second control instruction is out of service.
It is out of service it is described forbid loading process after, daily record process can then be recovered to load.
In the above-described embodiments, the classification of the daily record process or rank be a variety of, and described to forbid loading process to include pre-
If the classification or rank of forbidding loading daily record process, forbid described in the basis loading process forbid loading the daily record into
Journey, is specifically included with reducing the step S2 of I O access：
According to the default classification or rank for forbidding loading daily record process, forbid loading day of corresponding classification or rank
Will process, to reduce I O access.
Daily record process is used to load daily record, and the method that the present invention reduces onboard system I O access can be incited somebody to action according to the grade of daily record
Daily record process is classified by different brackets, the grade can be it is advanced, intermediate and rudimentary, specifically, advanced daily record pair
Loaded in requisition for advanced daily record process..In other embodiments, when the default classification for forbidding loading daily record process can be
Less than advanced, then forbid loading at this time it is intermediate with rudimentary daily record process, and then, it is intermediate to be not loaded with rudimentary daily record process
Level and rudimentary daily record, i.e. will only export high level daily record without output less than advanced daily record.
In conclusion for the method for the reduction onboard system I O access provided in the embodiment of the present invention, start onboard system,
The onboard system includes forbidding loading process and daily record process, according to it is described forbid loading process forbid loading the daily record into
Journey, to reduce I O access, and then can discharge CPU usage, the lifting system speed of service and system fluency, lift user
Experience.
