Heterogeneous dual-redundancy equipment running state data storage device and access method

The invention discloses a heterogeneous dual-redundancy equipment running state data storage device and an access method, the data storage device comprises a first storage unit and a second storage unit, and the first storage unit and the second storage unit adopt different hardware systems and different software systems; same equipment operation state data are stored in the first storage unit and the second storage unit, and the second storage unit serves as a redundant structure of the first storage unit. The storage unit provided by the invention adopts completely different hardware schemes and different software schemes to realize effective storage of running state information data of certain control equipment. According to the data storage device, the dual-redundancy design is adopted, the two storage units with the same function are used for completing effective storage of the operation state information data of a certain control device, and the dual-redundancy design enables the data storage device to
