Description
Technical field
The utility model is related to a kind of destruction state monitoring apparatus of the storage medium based on feedback mechanism.
Background technology
Existing storage medium high pressure destroys technology based on timing, and measure is to apply certain time on a storage medium
High pressure, enable storage medium burn failure.Its shortcoming includes：
1. if in Destruction mesohigh module error, storage medium is within a specified time unable to get correct pin
It ruins.
2. even with the storage medium of model, there is also inter-individual differences.Individual storage mediums may can bear longer
The high pressure of time is without being burned out.
3. often there are multiple storage mediums by destroying on product, if multiple storage mediums are carried out while being destroyed, that
Some storage medium may be burnt after high pressure destruction, at this point, the storage medium can absorb main high voltage electric current, enable it
Its storage medium can not be destroyed effectively.Therefore, current high pressure burns technology, needs to sell all storage mediums one by one
It ruins, causes to destroy overlong time, reduce product competitiveness.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and is provided a kind of based on feedback mechanism
The destruction state monitoring apparatus of storage medium.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
The utility model provides a kind of destruction state monitoring apparatus of the storage medium based on feedback mechanism, is stored at every piece
In medium power source path, detection circuit and ON-OFF control circuit is separately provided, and implements following control logic：In Destruction
In, the voltage difference between test point A and B in each storage medium power source path is monitored in real time；According to voltage difference, by high-precision current
Monitoring resistor resistance value, by I=U/R formula be calculated storage medium by current value；Due to electronic component failure original
Generally there are two kinds of situations after burning in reason, device：A. burn through-impedance becomes minimum；B. blow-impedance becomes very big；Therefore,
Detection confirms real-time current value not in normal range (NR) and is more than certain threshold value, and judgement storage medium is destroyed.
Further, in order to accelerate Destruction, electronic switch is individually set up for each storage medium, when storage medium pin
After ruining, that is, the storage medium power source path is turned off, influences high voltage power supply to avoid the storage medium destroyed.
The advantageous effect that the utility model is reached is：
1. if in Destruction mesohigh module error, controller can know that storage medium is not sold correctly
It ruins, and is according to circumstances further processed.
2. avoiding individual storage mediums that from can bearing the case where high pressure of long period is without being burned out, Destruction is enabled to continue
Until destruction.
3. during destroying storage medium one by one, as long as judging that certain medium is destroyed, you can terminate the medium immediately
Destruction and go to destruction stage of next medium, can shorten and overall destroy the time.
4. as high-pressure side electric current is enough, all storage mediums can be destroyed simultaneously.During destruction, to institute
There is storage medium to carry out poll one by one to judge, as long as judgement medium is destroyed, that is, disconnects the destruction voltage of the medium.With such
It pushes away, until the last one storage medium destroys completion, can substantially reduce and destroy the time.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not constitute limitations of the present invention together.In the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, a kind of destruction state monitoring apparatus of the storage medium based on feedback mechanism, in every piece of storage medium
In power source path, detection circuit and ON-OFF control circuit is separately provided, and implements following control logic：It is real in Destruction
When monitor voltage difference in each storage medium power source path between test point A and B；According to voltage difference, monitored by high-precision current
Resistance, by I=U/R formula be calculated storage medium by current value；Due to electronic component failure principle, device
Generally there are two kinds of situations after burning in part：A. burn through-impedance becomes minimum；B. blow-impedance becomes very big；Therefore, it detects
Real-time current value is confirmed not in normal range (NR) and is more than certain threshold value, and judgement storage medium is destroyed.
In order to accelerate Destruction, electronic switch is individually set up for each storage medium, after storage medium is destroyed, that is, is closed
The disconnected storage medium power source path influences high voltage power supply to avoid the storage medium destroyed.
The advantageous effect that the utility model is reached is：
1. if in Destruction mesohigh module error, controller can know that storage medium is not sold correctly
It ruins, and is according to circumstances further processed.
2. avoiding individual storage mediums that from can bearing the case where high pressure of long period is without being burned out, Destruction is enabled to continue
Until destruction.
3. during destroying storage medium one by one, as long as judging that certain medium is destroyed, you can terminate the medium immediately
Destruction and go to destruction stage of next medium, can shorten and overall destroy the time.
4. as high-pressure side electric current is enough, all storage mediums can be destroyed simultaneously.During destruction, to institute
There is storage medium to carry out poll one by one to judge, as long as judgement medium is destroyed, that is, disconnects the destruction voltage of the medium.With such
It pushes away, until the last one storage medium destroys completion, can substantially reduce and destroy the time.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
