Embodiment 1

[0025] A data storage method for self-contained applications. The method first separates the storage of data and the writing process of file system information. According to the number and capacity of cards in the system, the data format and location of the file system are planned, and the data The related operations of the storage and file system are carried out separately; multiple SD / TF cards are mapped into a virtual SD / TF card, and the collected data is written into each SD / TF card in turn in blocks; from the entire virtual From the perspective of SD / TF card, the storage format and location of the data meet the needs of building a file system, which is convenient for subsequent direct reading from the computer host; from multiple physical SD / TF cards, the data of the same file is parallel in blocks When writing to each SD / TF card, in the subsequent reading process from the host computer, it can support parallel reading through the multi-card controller.

Abstract

The invention relates to a data storage method and data storage system for a self-contained application, and belongs to the marine instrument field. According to the method, a plurality of SD / TF cardsare mapped into a virtual SD / TF card, collected data are sequentially written into the SD / TF cards in turn for storage; for the whole system, the write-in process is that the data is sequentially andalternately written into the SD / TF cards, the throughput of the SD / TF cards is fully utilized, and stable SD / TF card write-in performance is obtained to the maximum extent; and the data of the same file is written into each SD / TF card in parallel in a partitioning manner, so that the parallel reading through the multi-card controller can be supported in the subsequent reading process from the computer host. A required file system is unifiedly constructed, the data can be directly read by a computer, the reading process can be read from a plurality of SD / TF cards in parallel, and the data exporting speed is higher.

Description

Technical field [0001] The invention belongs to the field of marine instruments, and specifically relates to a data storage method and a storage system oriented to self-contained applications. Background technique [0002] Self-contained acquisition equipment currently has a wide range of applications in the field of marine instruments. The self-contained collection equipment storage system is characterized by sequential storage of sampled data and batch export after equipment recovery. Self-contained collection usually has a long working time and a large amount of data; the data storage rate is required to be stable during the storage process, and the data should not be lost; the data export process is fast, simple and easy to use. Considering the requirements of implementation complexity, cost, power consumption, etc., SD / TF cards are usually used to store sampling data, and file systems are used to organize and export data files. [0003] Traditional implementation methods usu...
