The preservation of event log data also can be preserved each data after storage triggers the time on date of taking place successively.
Fig. 3 (A) to (C) is the key diagram of expression at the continuous trigger respective operations of present embodiment.
300 have represented to trigger 310, and the state that wait before triggers takes place.In waiting for triggering state 300, preceding event log data take place owing to needing to preserve triggering 310, continue to be saved in data (carrying out data acquisition process) to SDRAM as basic operation.
320 have represented to become the scope of event log data of the conservation object of CF/SD.Expression be M second for trigger take place before, N second is for triggering between the storage life after taking place 320.
During CF/SD preserves 330, also can become halted state, not accept other operations.
The figure of the operation under the situation that Fig. 3 (A) takes place once to trigger for explanation.
After triggering 310 generations, wait for N after second (320 finish the back between storage life), beginning deposits (330) in to CF/SD.And, be that the state that next time triggers does not take place in CF/SD deposits the process of (330) in.After preservation is finished 340, restart data acquisition process, receive new triggering as basic operation.But, also have when preserving under the situations that finish back 332 generation triggerings at once the non-existent situation of event log data of M second.
Fig. 3 (B) is for illustrating the figure of the operation under the situation that recurs triggering.
After initial triggering 310-1 took place, N triggered 310-2 next time and takes place within second.In the case, 352 data became the data that deposited in CF/SD when finished the N second (350) after secondary triggering 310-2 takes place.As a result, 320 ' event log data are kept among the CF/SD between increased shelf-life.When transferring to for the second time, also take place equally just to prolong between storage life under the situation that back N triggers with interior generation second next time.But,, promptly stop to store to SDRAM if after SDRAM is filled with data.
Under the situation that SDRAM is filled with, the data of obtaining in for example between storage life have surpassed the capacity of SDRAM.The SDRAM that ring buffer constitutes in this case, will cover initial data.Therefore, under the situation about exceeding schedule time between storage life, can be to not carrying out above-mentioned data acquisition process during exceeding schedule time yet.
The SDRAM 50 of 128MB for example has been installed, has distributed under the situation of 112MB, if the full-size of jpeg data is 70KB then in the storage area of view data, can preserves about 26 seconds view data as the storage area of view data.Therefore, when surpassing under the situation of 26 seconds (stipulated time), between storage life for also can not carrying out above-mentioned data acquisition process during exceeding schedule time.

The situation that SDRAM is filled with for example also can be judged by the number of times that receives the triggering that takes place during the continuous trigger.That is, when the number of times that can work as the triggering that the continuous trigger reception period takes place reaches setting (triggering continuous maximal value), end above-mentioned data acquisition process.In addition, when the number of times that also can work as the triggering that takes place in the continuous trigger reception period reaches setting (triggering continuous maximal value), end between the prolongation storage life and during the continuous trigger.
The figure of the operation when Fig. 3 (C) takes place to trigger when data are saved to CF/SD 330 for explanation.
After initial triggering 310-1 ' took place, next triggering 310-2 ' had taken place in the process N above time of second.In the case, owing to begun to preserve data, ignore secondary triggering 310-2 ' to CF/SD (330).Promptly preserve during 330, do not carry out data acquisition process, also do not carry out the preservation to CF/SD for this reason from the SDRAM of correspondence as basic operation when data.
The processing flow chart when taking place is obtained and triggered to event log data when Fig. 4 takes place for triggering separately.
Simultaneously, Fig. 4 has represented to trigger the triggering generation task 410 that (with reference to Fig. 3 (A)) under the once situation takes place, the treatment scheme that data are preserved Processing tasks 420, data acquisition process task 440.
Preserve incident (for example collision waits, can judge the generation that collides according to the measured value of crash sensor) (412) if data take place, trigger generation task 410 sign is notified to data preservation Processing tasks 420.
Data are preserved task 420 receiving flags and are notified 414, obtain current time (422) earlier, and the N of regulation after the dormancy (424), generates event log data recording catalogue between second in CF/SD, and record constantly.Afterwards, use catalogue, then delete old catalogue (430) if generate the event log data preservation of Duoing than defined amount.After the dormancy of N between second finishes, data preserve Processing tasks 420 trigger take place with interrupting factor forbid requirement (426), data acquisition process task 440 stop requirement 428.
Deposit the event log data in CF/SD (430) successively by each tabulation afterwards.When preserve finishing at last, each of restarting to have stopped being handled requires 434 and trigger and take place to allow to require 432 with interrupting factor.
The processing flow chart when taking place is obtained and triggered to event log data when Fig. 5 takes place for the expression continuous trigger.
Simultaneously, Fig. 5 has represented to trigger the triggering generation task 510 of (with reference to Fig. 3 (B)) under the situation about recurring, the treatment scheme that data are preserved Processing tasks 520, data acquisition process task 540.
The initial data holding time 512 triggers generation task 510 sign is notified to data preservation Processing tasks 520 (514) after taking place.Data are preserved Processing tasks 520 receiving flags notice, at first obtain current time (522), in N dormancy between second (524) of regulation.Between this rest period, when data preservation incident 516 took place once more, triggering task 510 was waken data up and is preserved Processing tasks 520, sign is notified to data preserves Processing tasks 520 (518).Data are preserved Processing tasks 520 receiving flags and are notified 518, prolong between rest period (526).But, be N second of regulation between rest period in principle, but the M second before the initial triggering with initial triggering after the elapsed time and can not surpass maximum permitted hours.In the above processing, trigger and take place constantly can store 50 at most.After the dormancy of stipulated time finishes, in CF/SD, generate event log data recording catalogue, write down maximum 50 and trigger generation (532) constantly.
After dormancy finishes, data preserve Processing tasks 520 trigger the generation task with interrupting factor forbid requirement 528, data acquisition process task 540 stop requirement 530.
Deposit the event log data in CF/SD (532) successively by each tabulation afterwards.During this period,, also ignore this triggering inevitably even trigger again.After preserve finishing at last, each of restarting to have stopped being handled require 536 and the permission that triggers the interrupting factor that usefulness takes place require 534.
