example one
Referring to fig. 1, a hard disk destruction triggering method includes the steps of:
s1, receiving trigger signals sent by trigger terminals corresponding to different hard disk destruction types;
the hard disk destruction type comprises physical destruction and logical destruction, and if the triggering end is in a key form, the function of triggering physical destruction and logical destruction can be realized by one key;
s2, determining the duration of the trigger end in the first state according to the trigger signal;
specifically, when a first trigger signal indicating that the trigger terminal is in a first state and sent by the trigger terminal is received, timing is started;
when a second trigger signal which is sent by the trigger end and indicates that the trigger end is in a second state is received, timing is finished;
determining the time length of the triggering end in the first state according to the timing time length;
for example, if the trigger end is a key, when a first trigger signal that the key is pressed is received, timing is started, and timing can be performed by a timer;
when a second trigger signal for releasing the key is received, timing is ended;
determining the time length of the pressed key according to the timing time of the timer;
if the touch screen is the touch screen, the time of the touch screen being contacted can be timed to be used as the trigger duration;
if the trigger time is the toggle switch, the time for the toggle switch to be toggled to the preset position can be timed to serve as the trigger time;
s3, determining corresponding hard disk destruction types according to the time length, wherein the time length ranges corresponding to different hard disk destruction types are different;
specifically, the duration range corresponding to each hard disk destruction type may be set in advance, and the correspondence between the duration ranges may be stored, where the physical destruction corresponds to a first preset time range, and the logical destruction corresponds to a second preset time range, for example, the duration ranges may be set as follows:
the trigger duration range corresponding to the logic destruction is [3,5), namely the range is greater than or equal to 3 seconds and less than 5 seconds;
the trigger time length range corresponding to the physical logic is [5, + ∞), namely, the trigger time length range is greater than or equal to 5 seconds;
when the triggering duration of the triggering end is determined, searching which duration range the triggering end falls into from the corresponding relation stored in advance according to the triggering duration, and determining the corresponding hard disk destruction type according to the duration range in which the triggering end falls, wherein if the duration range in which the triggering end falls is 4 seconds, the duration range in which the triggering end falls is [3,5 ], and the corresponding destruction type is logic destruction; if 6 seconds, it falls into [5, + ∞), the corresponding type of destruction is physical destruction; if the time is 2 seconds, the operation is not performed within the preset time range corresponding to any hard disk destruction type, namely, no operation is performed within 3 seconds, and the condition that a user carelessly presses a key to trigger the destruction operation is prevented;
in another optional embodiment, the preset time range corresponding to each hard disk destruction type may be adjusted, specifically:
receiving a duration setting request, wherein the duration setting request comprises a hard disk destruction type and an updating duration range corresponding to the hard disk destruction type;
updating the corresponding duration range of the hard disk destruction type according to the updating duration range;

in another optional embodiment, in the timing process, a current timing value is obtained in real time, and when it is determined whether the current timing value is equal to a first preset value, if so, the destruction operation corresponding to the first hard disk destruction type is triggered to be executed, by such setting, it is avoided that the hard disk destruction operation is started after the triggering of the triggering end is finished, and in the triggering process, when a set triggering condition is met, the hard disk destruction operation is immediately triggered to be executed, for example:
assuming that a preset time length range corresponding to physical destruction is set to be [5, + ∞ ];
when the detected final time length that the key is pressed is 7 seconds, the triggered time length is counted, and if the corresponding physical destruction operation is executed after the counting is finished, 2 seconds of time will be wasted, and the physical destruction operation cannot be executed quickly;
by the processing mode of the embodiment, the current timing time can be acquired in real time in the timing process, if the timing time reaches 5 seconds, the physical destruction operation is executed immediately without waiting for the completion of the whole timing, so that the speed of executing the physical destruction operation is increased, the corresponding destruction type can be known in advance when the triggering operation is not completed, and the corresponding destruction operation can be executed immediately; the judgment of the hard disk destruction type and the execution of the destruction operation are advanced, and when the timing is finished, the subsequent judgment of the hard disk destruction type and the execution of the destruction operation are not required;
s4, executing corresponding destruction operation according to the determined hard disk destruction type;
after the hard disk destruction type is determined, corresponding destruction operations, such as logical destruction or physical destruction, can be executed according to the determined hard disk destruction type;
the above method steps may be performed by an MCU.

if physical destruction is triggered, physical destruction is executed when the triggering time length is counted to 5 seconds, so that judgment time length does not need to be executed when a key is released subsequently, and a corresponding type of destruction operation is executed according to the time length;
when the destruction function is completely executed, an indication instruction is sent to the indicator light, and the indicator light is normally off;
whether the button is pressed down, whether the destroying function is executed, what type of destroying function is executed and whether the destroying function is finished can be clearly known through the state indicating lamp;
in another alternative embodiment, the indication of different proceeding stages can be performed by the color of the indicator light, such as displaying red when the key is pressed, displaying green when physical destruction is performed, and displaying yellow when logical destruction is performed;
in another alternative embodiment, different hard disk destruction types can be distinguished through the flashing frequency of the indicator light or the color of the indicator light, and when the key is pressed, the indicator light is controlled to be on constantly, and when the destruction is completed, the indicator light is controlled to be off constantly.
