The application provides a vehicle battery management system parameter backup synchronization method, system and storage medium. The method comprises the following steps: an external diagnosis device sends a parameter backup instruction to an original battery management controller, the instruction comprising a backup instruction identifier and a cloud storage unit identifier; the original battery management controller sends a vehicle identifier, the cloud storage unit identifier and vehicle battery management system parameters to the cloud storage unit via an over-the-air technology module; after replacement with a new battery management controller, the external diagnosis device sends a parameter synchronization instruction to the new battery management controller; the new battery management controller sends a parameter acquisition instruction to the over-the-air technology module; and the over-the-air technology module acquires the vehicle battery management system parameters from the cloud storage unit and sends them to the new battery management controller for storage. The application solves the problems of parameter loss and failure to synchronize after replacement of the battery management controller.

This invention discloses a method for measuring the spatial distribution of the Fabry-Perot filter plate spacing based on solar observation, relating to the field of optical technology. The method includes the following steps: constructing an observation optical path so that sunlight, after passing through a lens group to form a telecentric beam, is perpendicularly incident on a Fabry-Perot filter composed of two parallel plates. The beam is then converged to a detector via an imaging mirror. The detector is used to acquire a two-dimensional spatial image of the sun, and the detector pixels correspond one-to-one with the plate areas of the filter. This invention directly utilizes the solar observation optical path during the measurement process, eliminating the need for additional dedicated measurement optical paths and equipment, significantly reducing system complexity, minimizing the risk of errors during equipment installation and debugging, and effectively controlling development costs. The spatial distribution of the plate spacing can be measured synchronously during normal solar observation without interrupting the observation process, enabling real-time monitoring of the Fabry-Perot filter's status and ensuring the continuity and integrity of the observation data.
