Abstract: A hardware queue handling system and method, a solid state drive controller, and a solid state drive are disclosed. A main module of a hardware queue handler module and a mapping module of the hardware queue handler are connected respectively to one of the processing module or hardware module through an internal bus in a vicinity; a synchronizer module is configured to actively synchronize information between the main module and the mapping module.

Abstract: Disclosed is a decision method of condition-based maintenance to a power grid risk. The method includes: calculating a contribution of each device to be maintained of a plurality of devices to be maintained to the power grid risk in a current operation mode of a power grid, and determining the contribution of the each device to be maintained to the power grid risk as a set value corresponding to the each device to be maintained; determining a maintenance decision order of the devices to be maintained according to a descending order of set values corresponding to the devices to be maintained; and sequentially making maintenance decisions on the devices to be maintained according to the determined maintenance decision order.
