Step e also comprises, with depositing the mapping unit in the volatile memory respectively in behind the accumulative total driving mileage data interpolation check code; Through the enforcement of step F and A, after the mileage record device restarted, at first the Backup Data of map over unit carried out its validity of verification judgement, if Backup Data is effective, then used the Backup Data of mapping unit to recover the accumulative total driving mileage data, continued to add up.
To add up driving mileage data in the step e and deposit in the nonvolatile memory simultaneously and back up, be accumulative total driving mileage data in the accumulative total driving mileage data mapping unit in the volatile memory to be deposited in back up in the nonvolatile memory; After system restarts,, then use the effective Backup Data in the nonvolatile memory backup units to recover the accumulative total driving mileage data at every turn, continue statistics if the Backup Data of mapping unit is invalid.
At vehicle out of service or continue to go reach regular time during section execution in step E with mapping unit in Backup Data deposit in the nonvolatile memory respectively and back up.
The utility model workflow is referring to Fig. 2, and at first execution in step S01 judges the current travelling speed of vehicle, when travelling speed during more than or equal to 5km/h; Execution in step S02; From the reflection of data storage cell internal memory ram buffer, read the Backup Data of accumulative mileage data, and calculate its effect sign indicating number, if the effect sign indicating number that calculates is consistent with the effect sign indicating number of Backup Data; Then the Backup Data of accumulative mileage data is effective; Execution in step S03 removes the effect sign indicating number of Backup Data, and it is subsequent use to put into internal memory RAM accumulative mileage data variable unit, changes step S07.Otherwise the accumulative mileage Backup Data is invalid in the internal memory ram buffer; Execution in step S04; Read the Backup Data of accumulative mileage data nonvolatile memory from data storage cell---the flash memories, and calculate its effect sign indicating number, if the effect sign indicating number that calculates is consistent with the effect sign indicating number of Backup Data; Then the Backup Data of these accumulative mileage data is effective in the flash memories; Execution in step S05 removes the effect sign indicating number of this Backup Data in the flash memories, and it is subsequent use to put into internal memory RAM accumulative mileage data variable unit, changes step S07.Otherwise the Backup Data of this accumulative mileage is invalid in the flash memories; Get the Backup Data of another accumulative mileage data from the nonvolatile memory flash memories is stressed, and calculate its effect sign indicating number, if the effect sign indicating number that calculates is consistent with the effect sign indicating number of Backup Data; Then the Backup Data of these accumulative mileage data is effective in the flash memories; Execution in step S05 removes the effect sign indicating number of this Backup Data in the flash memories, lets in internal memory RAM accumulative mileage data variable unit subsequent use, changes step S07; Otherwise can't read correct mileage statistics in above-mentioned two types of backups, need carry out the mileage statistics again, execution in step S06 is subsequent use with accumulative mileage data variable unit zero clearing among the internal memory RAM, changes step S07.
Step S07 starts every timer that sent a look-at-me at a distance from 1 second in the analytical calculation module, and counting variable unit zero clearing among the internal memory RAM second is subsequent use, changes step S08.
Step S08, the analytical calculation module is received a look-at-me that above-mentioned timer sends with regard to execution in step S09, otherwise the analytical calculation module is carried out other program.
Step S09, the analytical calculation module is received the vehicle location signal that the signals of vehicles sending module of cab signal receiver module transmission sends, and judges whether to receive effective position signalling.If the data received are effective, execution in step S10 then, otherwise return step S08.
Step S10, the analytical calculation module obtains the position of vehicle according to the effective vehicle location signal that receives, and carries out S11 then.
Step S11, the distance of second adjacent 2 vehicle ' before and after the analytical calculation module goes out according to adjacent two time points that receive (hereinafter to be referred as front and back seconds) vehicle positional information calculation on the line.Execution in step S12 then.
Step S12; The analytical calculation module is added to above-mentioned distance and adds up in the data of driving mileage data variable unit; Execution in step S13 backs up the mapping unit in the internal memory ram buffer that deposits data memory module behind the data interpolation check code that adds up driving mileage data variable unit in then.Next execution in step S14, the analytical calculation module adds one with the data of among the data storage cell internal memory RAM second counting variable unit.
Get into step S15, in the analytical calculation module judgment data memory module among the internal memory RAM data of second counting variable unit whether equal 28800, promptly vehicle goes continuously and writes 8 hours all over, is execution in step S16 then, otherwise execution in step S08.This is frequent flash memories to be carried out erasable in order to prevent, only revises the mileage of the per second statistics in the internal memory ram buffer mapping unit, Cai per eight hours are saved in the Backup Data in the internal memory ram buffer mapping unit in the flash memories.
Step S16, the analytical calculation module is with the data zero clearing of among the data memory module internal memory RAM second counting variable unit.For next circulation is prepared.Then step S17, the analytical calculation module is deposited data memory module among the RAM that the Backup Data of mapping unit deposits two storage unit in the data storage cell flash memories respectively in the buffer zone, and the total kilometrage data are backed up.Execution in step S08 then.
Receive in the process of the look-at-me that timer sends that in analytical calculation module execution in step S08 wait the program that the analytical calculation module is carried out other comprises that the log-on message display unit shows the statistics in the accumulative total driving mileage data variable unit.
The processing procedure of data memory module when Vehicle Speed does not reach setting value.Comprise that also the Backup Data with mapping unit in the buffer zone among the data storage cell internal memory RAM deposits two storage unit in the data memory module flash memories respectively in, backs up the total kilometrage data.
