These volatile data are usually written into the non-volatile storage device at fixed time intervals. If a power failure occurs during the data writing process, the data being written may be abnormal error data. Air conditioner operating parameters If there is an error in the stored data, usually you can only restore the factory settings, then the historical data stored in the air conditioner will be lost, affecting the normal use of the air conditioner

The invention discloses an air conditioner parameter storage method and device and a storage medium, and belongs to the field of air conditioners. The method comprises the steps that when the air conditioner control panel is powered on, data of a read-write area of a nonvolatile memory are read, and the data of the read-write area are verified; when the verification of the data in the read-write area fails, the data in the backup area of the nonvolatile memory are read, and the data in the backup area are verified; and when the verification of the data in the backup area succeeds, the data inthe backup area are written into the read-write area. The normal data of the backup area of the nonvolatile memory is written into the reading area, so that the data of the reading area is recovered to be normal, and the air conditioner can be switched into normal operation according to the data of the reading area. Meanwhile, the air conditioner does not need to restore factory settings, historical data stored in the air conditioner are not lost, and normal use of the air conditioner is guaranteed.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner parameter storage method, device and storage medium. Background technique [0002] With the development of electronic information technology, high-end air conditioner control panels are generally equipped with non-volatile storage devices, such as EEPROM, FLASH, etc., to record some variable data, such as running time, operating mode, set temperature, Important data such as wind speed. These volatile data are usually written into the non-volatile storage device at fixed time intervals. If a power failure occurs during the data writing process, the data being written may be abnormal error data. Air conditioner operating parameters If there is an error in the stored data, usually you can only restore the factory settings, then the historical data stored in the air conditioner will be lost, affecting the normal use of the air conditioner.
