The invention discloses a device power-down operation parameter read-write exception protection method and system and a storage medium, and the method comprises the steps: determining that a device ispowered down, and obtaining an operation record of an operation parameter; determining that the operation record is not null, and storing power-down backup data of the plurality of operation parameters; determining that the equipment is powered on, and obtaining the power-down backup data; and determining that the data verification of the power-down backup data is correct, and reading the power-down backup data as an operation parameter. According to the embodiment of the invention, the operation record of the equipment operation parameter can be obtained after the equipment is powered off, and the operation parameter of the equipment can be stored as a plurality of backup power-off backup data under the condition that the operation record is not empty. Compared with an existing power-down memory method, the reliability of reading and writing of the power-down operating parameters of the equipment is improved by increasing the backup number of the power-down backup data. The method and system can be widely applied to the technical field of power failure protection.
Description
technical field [0001] The present application relates to the technical field of power-off protection, and in particular to a protection method, system and storage medium for abnormal reading and writing of equipment power-off operation parameters. Background technique [0002] The existing power-off memory method is to store the operating parameters of the device in the power-off holding register before the device is powered off. After the device is powered on again, the operating parameters in the power-off holding register can be read and restored according to the operating parameters. The operating state of the device. In the current power-off memory method, when the device is over-discharged or the storage device is abnormal, part of the backup data is lost, and it is easy to have an abnormal data verification during the reading process of the backup data, which makes the reliability of the device power-off memory low. . Contents of the invention [0003] In view of...
