摘要
由于实验室嵌入式系统日志数据丢失量较大,现有的数据恢复方法在实际应用中无法实现数据最大比例恢复,数据恢复量较少。为此,提出基于时效规则的实验室嵌入式系统日志数据恢复方法。阐述了实验室嵌入式系统日志数据恢复现状,针对传统方法存在的问题,对基于时效规则的实验室嵌入式系统日志数据恢复方法进行设计。首先对建立的数据组遍历,根据遍历信息确定数据是否为丢失数据,并根据映射关系确定丢失数据所对应的物理地址。然后提取实验室嵌入式系统日志数据状态时效规则,在此基础上通过对提取的时效规则支持度计算,确定数据属性的时效顺序。按照顺序对数据进行还原和恢复,从而完成基于时效规则的实验室嵌入式系统日志数据恢复。经实验证明,设计方法数据恢复量大于传统方法,更优于传统方法。
Due to the large amount of data loss in the embedded system,the existing data recovery methods can not achieve the maximum proportion of data recovery in practical applications,and the amount of data recovery is less.A method for the recovery of embedded system log data based on the rule of time limitation is proposed.In this paper,the present situation of the data recovery of the laboratory embedded system is described,and the embedded system data recovery method based on the aging rule is designed according to the problems existing in the traditional methods.Firstly,through traversing the set of data,whether the data is lost data or not is determined according to traversal information,and the corresponding physical address is determined according to the mapping relationship.Then,the time-effect rules of the embedded system log data are extracted,and the time-effect order of the data attributes is determined by calculating the support degree of the extracted time-effect rules.The data is restored and recovered sequentially,thus completing the embedded system data recovery based on the aging rule.The experimental results show that the data recovery of the design method is larger than that of the traditional method,which is better than the traditional method.
