Abstract
The invention belongs to structure-design technique field, particularly a kind of antiwithdrawal device.Its technical scheme is: under abnormal condition, ensure that upper shell and the lower house of card charge machine are opened, tamper compressing tablet between upper shell and lower house flicks, tamper compressing tablet is in off-state, described power supply unit cannot provide power supply to described control chip, and the time of described clock unit reverts to initial time; When the upper shell and lower house that ensure card charge machine close tightly, after tamper compressing tablet is in and closes, described control chip detects that the time showing of described clock unit is abnormal, then stop starting the whole system work ensureing card charge machine, and by described display unit prompting input tamper password.It is high that the present invention has tamper rank, the feature that tamper principle is hidden, as long as ensure that card charge machine shell was opened, even if just in a flash, also can be detected by control chip.
Description
Technical field
The invention belongs to structure-design technique field, particularly a kind of antiwithdrawal device.
Background technology
Now decomposing prevention circuit commercially generally only adopts hardware tamper design, tamper rank is not strong, than if any tamper design only adopt a kind of microswitch reality, as long as microswitch is pressed, equipment can normally work, this kind of tamper design concept is simple, is very easy to be disassembled personnel and gets around, lose the object of tamper.
Summary of the invention
The object of the invention is: a kind of antiwithdrawal device is provided, prevent the potential safety hazard that unwarranted illegal detaching equipment causes.
Technical scheme of the present invention is: a kind of anti-dismantle security card consumption machine, is characterized in that, it comprises: upper shell, lower house, central circuit plate and display screen;
Described central circuit plate comprises: power supply unit, tamper compressing tablet, control chip U14 and clock unit; Described power supply unit is divided into two-way to input, one tunnel connects power supply, another road meets button cell BT2, the anode of Power supply access diode D11, the anode of button cell BT2 mono-tunnel access diode D12, separately lead up to electric capacity C53 ground connection, diode D11 is connected with the negative electrode of diode D12, and its contact is communicated with described control chip U14 by described tamper compressing tablet; The two ends of the clock Y2 in described clock unit are respectively by electric capacity C54, C55 ground connection, and resistance R42 is connected in parallel on clock Y2 two ends, two tip node Access Control chip U14;
There is a raised structures below of described upper shell, described central circuit plate is arranged between described upper shell, lower house, tamper compressing tablet on it is just to the projection of the below of described upper shell, when the upper shell of guarantee card charge machine and lower house close tight, the two ends of tamper compressing tablet are compacted, described display location in the surface of described upper shell, and is connected with the output of control chip U14.
The invention has the beneficial effects as follows: it is high that (1) the present invention has tamper rank, the feature that tamper principle is hidden, as long as ensure that card charge machine shell was opened, even if just in a flash, also can be detected by control chip.
(2) clock unit is used for decomposing prevention circuit design by the present invention, tamper action can be remembered by hardware, and become the key Design that control chip can detect tamper action.
(3) after ensureing the dismounting of card charge machine, must input tamper password, the system be disassembled like this has to pass through genuine process and could use further, the system be disassembled can be known by genuine, really reach the object of tamper.
Accompanying drawing explanation
Fig. 1 is principle of the invention block diagram;
