Equipment usage time recording method and device thereof

The invention relates to the computer field, and discloses an equipment usage time recording method and a device thereof; the method comprises the following steps: updating data, representing equipment usage time and stored in a first, second and third storage space, according to an updating cycle when the equipment is in a running state; reading three sets of data stored in the storage spaces when the equipment is started; selecting the larger data from the two sets of data as the initial data of the equipment usage time, wherein difference value of the two sets doubles the update cycle, or selecting the largest data from the three sets of the data as the initial data of the equipment usage time; using the selected initial data to update the data in the first, second and third storage spaces. When data is inputted in the storage space, equipment shutdown or sudden power off will cause inputting data errors, thus causing the whole usage time recording failure; the novel method and device can solve said proble
