Abstract
The invention provides an anti-counterfeiting recognition device provided with a self-destructive protection assembly. The device comprises a top shell, a bottom shell, a battery fixed into the bottom shell and a circuit board connected with the battery, and further comprises at least one voltage detection device used for detecting voltage signals. The voltage detection device is connected with a main control module. The top shell is further provided with at least one convex column extending to the inside of the bottom shell, and the bottom of the convex column is in contact with the voltage detection device so as to generate the voltage signals. A method for using the device includes the steps that the main control module reads the voltage signals input by the voltage detection device in real time; when the main control module can not detect the voltage signals input by the voltage detection device in real time, the main control module starts a self-destructive program so as to delete data stored in a memory. When the device is detached illegally, the main control module can quickly delete all the data and programs in the memory at the moment that the top shell is separated from the bottom shell, so that the data and the programs in the memory are prevented from being read illegally.

Summary of the invention
For the weak point existing in the problems referred to above, the invention provides a kind ofly in the time that anti-counterfeit recognition equipment is illegally dismantled, can delete rapidly the anti-counterfeit recognition equipment with self-destruction guard assembly and the self-destruction means of defence of total data and program in storer.
For achieving the above object, the invention provides a kind of anti-counterfeit recognition equipment with self-destruction guard assembly, the circuit board that comprises top shell, drain pan and be fixed on the battery of described drain pan inside and be connected with described battery, also comprise at least one pressure-detecting device for pressure signal is detected, described pressure-detecting device is connected with the main control module being solidificated on described circuit board; In described top shell, be also provided with at least one to the inner projection extending of described drain pan, the bottom end face of described projection contacts with described pressure-detecting device, to produce pressure signal.
The above-mentioned anti-counterfeit recognition equipment with self-destruction guard assembly, wherein, described main control module is connected with described pressure-detecting device by I/O interface.
The above-mentioned anti-counterfeit recognition equipment with self-destruction guard assembly, wherein, described pressure-detecting device is pressure transducer, its quantity is identical with the quantity of described projection.
The self-destruction means of defence that the invention provides a kind of anti-counterfeit recognition equipment with self-destruction guard assembly, comprises the following steps:
S10, device initialize;
S20, pressure-detecting device input to generation pressure signal in main control module;
Whether S30, master control module judges have detected pressure signal input, if the determination result is YES, perform step S40, make the system continuation maintenance duty with the equipment of self-destruction protective device; If judged result is no, perform step S50, main control module is deleted the program of the data and system in storer self;
S60, judge whether the system of equipment to be switched to battery saving mode, if the determination result is YES, perform step S70, the operational mode of system is switched to battery saving mode; If judged result is no, perform step S80, make system continue to remain current running status;
Main control module is triggered in S90, wake-up waiting source, to return to execution step S40.
Compared with prior art, the present invention has the following advantages:
To invention while illegally dismantling, main control module can be in top shell and the drain pan time of releasing be deleted storer rapidly total data and program, to avoid data and program in storer illegally to be read.

Embodiment
As shown in Figure 2, the present embodiment provides a kind of anti-counterfeit recognition equipment with self-destruction guard assembly, comprise top shell 1, drain pan 2 and be fixed on the battery 4 of drain pan inside, and the circuit board 3 being connected with battery 4, and be solidificated on circuit board and be connected with main control module (not describing in figure), pressure-detecting device 6 for pressure signal is detected.
In top shell 1, be also provided with the projection 5 extending to the inner surface direction of drain pan 2, the bottom end face of this projection 5 contacts with pressure-detecting device 5, to produce pressure signal.Main control module is connected with pressure-detecting device by I/O interface, to receive the real-time pressure signal of pressure-detecting device input.
Wherein, pressure-detecting device is pressure transducer, and its quantity is identical with the quantity of projection.
The present invention is by the projection that has increased pressure-detecting device and matched with it in device case inside, therefore, in the time that top shell and drain pan are interlocked, thereby projection contacts with pressure-detecting device and produces pressure, is solidificated in the pressure signal that the main control module on circuit board produces by I/O interface detected pressures pick-up unit.Merge while remaining intact state when top shell and drain pan interlock, main control module can normally detect pressure signal, and therefore, the system in device can keep normal duty.In the time that top shell is separated with drain pan, the projection in top shell also no longer contacts with pressure-detecting device, cannot produce pressure signal.Because main control module cannot detect the pressure signal that pressure-detecting device produces, therefore, main control module starts self-destruction program, and the data and system program in storer is deleted, to avoid data and program in storer illegally to be read, and device cannot normally be worked.
In the time that the pressure signal that pressure-detecting device is produced detects in real time, main control module adopts the method for I/O interface external interrupt, that is, in the time that the level of I/O interface changes, the interrupt routine that operation is specified at once.Like this, when the equipment with self-destruction protective device under normal operation mode without any problem, and also can from battery saving mode, be waken up at once during at battery saving mode when equipment, be switched to the interrupt routine that normal mode of operation operation are specified, can power saving can in the time that apparatus casing be disassembled, wake rapidly and delete again data up like this.
As shown in Figure 3, the invention provides a kind of self-destruction means of defence of the anti-counterfeit recognition equipment with self-destruction guard assembly, comprise the following steps:
S10, device initialize;
S20, pressure-detecting device input to generation pressure signal in main control module;
Whether S30, master control module judges have detected pressure signal input, if the determination result is YES, perform step S40, make the system continuation maintenance duty with the equipment of self-destruction protective device; If judged result is no, perform step S50, main control module is deleted the program of the data and system in storer self;
S60, judge whether the system of equipment to be switched to battery saving mode, if the determination result is YES, perform step S70, the operational mode of system is switched to battery saving mode; If judged result is no, perform step S80, make system continue to remain current running status;
Main control module is triggered in S90, wake-up waiting source, to return to execution step S40.
Only as described above, be only preferred embodiment of the present invention, such as professional who are familiar with this art.After understanding technological means of the present invention, natural energy, according to actual needs, is changed under instruction of the present invention.Therefore all equal variation and modifications of doing according to the present patent application the scope of the claims, once should still remain within the scope of the patent.
