Reinforced multi-solid-state hard disk and power-up automatic hard burning method thereof

Abstract

The invention discloses a reinforced multi-solid-state hard disk and a power-up automatic hard burning method thereof. The reinforced multi-solid-state hard disk comprises N solid-state hard disks, adecision circuit, a constant current source circuit, a DC-DC conversion circuit, a burning controller, a decoder, N constant current power switches and a soft destruction switch. The decision circuitis connected with an external burn-out power supply, a hard disk working power supply and a burn-out controller; the DC-DC conversion circuit converts the burning power supply into a working power supply for burning the controller and the decoder; the constant-current source circuit is connected with a burning power supply; two ends of the constant-current power supply switch are respectively connected with the constant-current source output power supply and the corresponding solid-state hard disk; the address end of the decoder is connected with the burnout controller, and the data end of thedecoder is connected with the corresponding constant-current power switch control end; and each constant-current power switch is controlled to be switched on and off by a digital decoding signal output by the decoder, namely whether a power supply output by the constant-current source is allowed to supply power to the corresponding solid-state hard disk for hard burning or not. According to the invention, hard burnout control in a complex electromagnetic environment is more stable.

Description

technical field [0001] The invention relates to the field of burning solid-state hard disks, in particular to a reinforced multi-solid-state hard disk and a method for automatically burning hard disks when power is applied. Background technique [0002] At present, more and more attention has been paid to the issue of information security. In special application environments, it is necessary for solid state drives to have the ability to be hard destroyed under certain conditions. When the hardened solid state drive is lost, there is a risk of data loss, so it is particularly important to completely burn the data in time. [0003] If the burning time of the solid-state hard disk is short, the FLASH in the electronic disk will be burned incompletely, and the purpose of completely burning the information of the electronic disk cannot be achieved; if the burning time of the solid-state hard disk is long, it will easily cause a short circuit and cause the circuit board to burn ou...
