Abstract

The invention discloses an airborne environment serial advanced technology attachment (STAT) bus storage control system and a control method of the airborne environment STAT bus storage control system. The system comprises a communication interface module, a cache module, a control module, a processing module, a SATA controller, a photoelectric sensor, a power module and a storage medium. The communication interface module provides an interface for connection with a host computer. The cache module is used for receiving and storing data to be read in temporally and informs the host computer of the read-in data through the communication interface module. The control module is used for logic control, processing signals of the photoelectric sensor and informing the host computer to operate correspondingly, and controlling the power module to conduct power management of the storage medium. The processing module is used for data package transportation and computing processing, and storing the processing core for the SATA bus. The SATA controller is used for integrating a SATA bus protocol and conducting SATA bus connection and communication through the storage medium. The airborne environment STAT bus storage control system and the control method of the airborne environment STAT bus storage control system are safe and reliable in data storage and usage.

Description

technical field [0001] The invention relates to a storage control technology, in particular to an airborne environment SATA bus storage control system and a control method thereof. Background technique [0002] The SATA protocol is a SATA standard formulated by the International Serial ATA Organization SATA-IO. Its main performance characteristics are: [0003] (1) The transmission speed is fast, the transmission rate of SATA1.0 is 1.5Gbps, and the transmission rate of SATA2.5 is 3.0Gbps; [0004] (2) The cable width is reduced and the length is increased. The width is reduced from 40 / 80 pins of IDE to 7 pins, and the length is increased from 18 inches to 1 meter; [0005] (3) Support hot swap; [0006] (4) Improve the accuracy of data transmission, SATA improves the error detection of CRC on data, commands and status packets, and improves the accuracy of data transmission; [0007] (5) Low-voltage differential signal is used, the voltage difference at the sending end is...
