Problems solved by technology

At present, commonly used large-capacity storage media include SD / TF card and hard disk. The former has low power consumption, but the storage capacity is limited; the latter can provide relatively large storage capacity, but the power consumption is much higher than SD / TF card. Even solid-state drives (SSDs) still consume an order of magnitude more power
In addition, conventional embedded system controllers are equipped with limited SD / TF interfaces and hard disk interfaces, limited by the maximum capacity of a single memory, and the maximum capacity of the storage system is also very limited

Abstract

The invention relates to a low-power-consumption large-capacity storage system and an application, within the field of ocean instruments. The system is extended to a plurality of paths through a matrix controller, and a plurality of TF / SD cards are mounted on each SDIO bus. The data writing process adopts the time division mode, only one SDIO channel and one TF / SD card on the SDIO channel are selected by the MCU, and the other TF / SD card closes the power supply and carries out low power consumption processing. The data reading process simultaneously selects all the SDIO channels, and the TF / SDcard data of each channel are output in parallel so as to achieve fast reading.

Description

technical field [0001] The invention belongs to the field of marine instruments, and in particular relates to a low-power consumption large-capacity storage system and its application. Background technique [0002] Self-contained acquisition equipment is currently widely used in the field of marine instruments. The self-contained acquisition device storage system is characterized by sequential storage of sampled data and batch export after device recycling. The storage process requires low power consumption and the export process requires high speed. Typically, the two main factors affecting the operating time of a self-contained capture device are storage capacity and power consumption. At present, commonly used large-capacity storage media include SD / TF card and hard disk. The former has low power consumption, but the storage capacity is limited; the latter can provide relatively large storage capacity, but the power consumption is much higher than SD / TF card. Even solid...
