Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the workflow diagram of the present invention.
Fig. 2 is the principle schematic of the present invention.
Detailed description of the invention
With reference to Fig. 1, the workflow of the present invention is as follows: one be 5V power supply be that solid state hard disc is powered, it starts normally to work；
Two is that energy supply control module monitors self-destruction signal level state in real time；
Three is that energy supply control module judges whether self-destruction signal level state is level "0" state, if it is judged that no, then hold
Row step S4, if a determination be made that, then perform step S5；Four is that energy supply control module is powered also still in off state, 5V
Not being input in each low-voltage chip of solid state hard disc, hard disk normally works；Five is that energy supply control module becomes conducting state, 5V
Power supply is directly inputted in each chip of solid state hard disc；Six is that 5V powers and is directly inputted to controller and the storage of solid state hard disc
In the low-voltage chip such as unit, burn all chips, complete hard disk self-destruction operation.
The 5V that hard-disk interface provides only is powered by the design of conventional solid-state hard disk and is converted into the voltage of 3.3V or 1.8V
Change-over circuit, controller and memory element for hard disk power, and conventional hard disk self-destruction method is that computer is transmitted by data
Passage is write " 0 " in hard disk controller and memory element, and till hard disk is fully written, the method that data destroyed by this clock is the longest
And having the possibility that data are resumed, it can be seen that the method operability and reliability are the most relatively low, can not meet some field again
The demand of emergency.
