【Abstract】 To meet the demands of repeated experiments, partitioned storage, and multi-channel data recording in various testing environments such as ground tests and flight tests for guided munitions, a design for a multi-partition, multi-channel recorder is proposed. This recorder uses NAND FLASH as the storage medium. By designing a storage state detection algorithm, data can be stored in partitions based on the current recording status and the number of records since the last erasure. An ARM Cortex-M7 based microcontroller serves as the main controller, utilizing dual-port buffers to transfer data from the buffer to storage, and implementing appropriate interrupt operations to achieve multi-channel analog and digital data acquisition. This design not only improves the storage utilization of the projectile-borne data recorder but also enhances testing efficiency in various projectile-borne testing environments. Ground and flight test validations and analysis results demonstrate that this recorder can reliably achieve partitioned recording of 8-channel analog signals and 5-channel digital signals as needed. It provides valuable insights for the design of recorders in other projectile-borne recording environments.更多还原
