Background technology
Locomotive EMS needs to record the consumption information of locomotive, the including but not limited to energy of locomotive consumption, machineEnergy that the energy of car resistive braking consumption, locomotive regenerative braking produce etc..Locomotive EMS utilizes the energy consumption of locomotiveThe energy consumption of locomotive is analyzed in Information Statistics, is that data supporting is done in locomotive energy consumption optimization.The effectiveness of energy consumption data just seems outstandingFor important.Locomotive energy consumption information Store, in mobile unit, periodically can import to ground system by number of ways, by groundPlane system completes energy consumption analysis.Mobile unit is to the key link that the storage of consumption information is EMS.Consumption informationIt is incremented by with locomotive operation, if equipment replacement, storage failure or random power-off etc. cause energy information to lose, canConsumption management system tanglewracks, irrecoverable.
Locomotive energy consumption information backup and the synchronous mode generally relying on redundancy backup solve.Storage dress in consumption informationOutside putting, other car-mounted devices back up energy information.According to certain cycle, energy information is stored back-up device, can be byAccording to certain strategy, as above during electricity, consumption information is fetched, and determines selected value etc. using voting mechanism between multiple backup informations.ButHave the following disadvantages：(1) back up between mobile unit：Each equipment room operating mode difference, is all unmanned equipment, does not have foreign interventionIn the case of, the selection of backup cycle, the selection of synchronized algorithm, coordination of the maintainer of different majors etc., all can affect numberAccording to effectiveness.It is impossible to play the effect of backup, there is the wind of consumption information loss using backup information in long backup cycleDanger；The backup cycle of overfrequency, affects service life of equipment, and particularly, not all equipment all possesses the ability of specialty storage；WithThe maintainer of the selection of step algorithm and different majors is coordinated, and energy backs up on different devices, by the maintenance of different majorsPersonnel safeguard, back-up device quantity is less than 3, then can not form voting mechanism；Particularly back-up device needs to overhaulWhen exchanging between different locomotives, the energy information between locomotive necessarily causes confusion；Using the backup of more devices, then increase systemComplexity, be simultaneously introduced more uncertain factors.(2) energy information storage redundant configuration：Increase cost.
