Embodiment

Preferred embodiment of the present utility model is described in detail below.

The false proof chip circuit of the utility model equipment consumptive material, as depicted in figs. 1 and 2, in existing common anti-tseudo circuit On basis, mainly set and use control chip for safety chip, can be, but not limited to BCM5892 series, fly this karr K21 series etc., key is stored using safety chip and is decoded, and sets self-destruction program when meeting with physics decryption, simultaneously All or part of mathematical algorithm needed for equipment to be completed to its Core Feature is completed by the chip, such as, but not limited to printer Ink-jet algorithm, analytical instrument signal or parameter algorithm etc., the safety chip may also be used for storage and completes calculation function Sequential or driver etc., are data necessary to being realized by false proof equipment in a word, and the data should be not easy to be imitated Complicated random data.It can thus cause：1st, chip meeting self-destruction during physics is decrypted, it is impossible to decrypt；2nd, chip Output is not simple License Info but complicated result of calculation, even if code breaker has method to get around chip, also cannot Correct result, it is impossible to get around chip counterfeit.

As shown in figure 1, the utility model is typically used in anti-fake consumable item, print cartridge, the toner cartridge of such as printer, or, doctor The kit used in the in-vitro diagnosis equipment for treating equipment；Anti-fake consumable item generally comprises consumption part and main part, such as body The reagent bottle that outer diagnostic device is used, reagent bottle is the toner cartridge that reagent is consumption part, for another example printer in main part, bottle, Powder/selenium cartrige is that the ink powder in main body, powder/selenium cartrige is consumption part.Anti-counterfeit bar code is generally located in the main part of anti-fake consumable item, Bar code or Quick Response Code 100 are for example set, as shown in figure 1, including bar code input module 200 using the equipment of consumptive material（Such as bar code Scanner）, using the control chip 500 of safety chip（Such as BCM5892 series, fly the K21 series of this karr）, a performing module 300（Such as the measurement module of the document input module of printer, or, in-vitro diagnosis equipment）, and an output module 400（As printed The print module of machine, the display module of diagnostic device）.Decoding unit 501 and device core algorithm are provided with safety chip 500 Unit 502（Such as ink-jet algorithm, the analytical instrument parameter algorithm of printer）.

Wherein bar code 100 is used for the authentication information for preserving anti-fake consumable item, to determine anti-fake consumable item really for production The qualified products that business is produced.Authentication information is information of the manufacturer by encryption, such as encrypted characters string, these encryption letters Breath is that can uniquely refer to the anti-fake consumable item after decryption, so as to play false proof effect.The false proof principle is existing Known to technology, do not repeating herein.

The bar code input module 200 is used to obtain the authentication information preserved in bar code 100, and it is to bar code 100 The corresponding false proof data of acquisition are scanned, and by the information data transmission to safety chip 500.

A decision circuitry is provided with the safety chip 500, for the function of being cracked with resistance against physical, is judging described When safety chip receives physics and cracks action, self-destruction program can be started, you can to improve the voltage of chip, to burn safe core Piece.The decision circuitry of the safety chip ensure that chip is removed also reading data；Once physics is detected to crack Behavior, chip will improve voltage self-destruction.

Be stored with decoding program in the decoding unit 501, for being decoded to the false proof data from the bar code, Its authentication information is determined, so as to judge whether consumptive material is qualified products, and decoded result the performing module is transferred to 300。

The performing module 300, which is used to obtaining equipment, completes data needed for its Core Feature.Device core function refers to Equipment with name function, the printing function of such as printer, the blood count function of cellanalyzer etc., with respect to this reality For the new anti-tseudo circuit of safety chip, the work system of original function can be regarded as.

Wherein described core algorithm unit 502 is calculated for all or part of data processing needed for equipment completes its Core Feature Method, as realizes the core data Processing Algorithm of original function, the print data processing of such as printing function, vitro detection function Detection data processing and judgement.

The output module 400 is exported for the result for handling core algorithm 502, can be display dress Put or printer in print module.

Carried out furtherly below in conjunction with chip circuit method for anti-counterfeit false proof to equipment consumptive material of the present utility model Fig. 2 It is bright：

As shown in Figure 2, its method for anti-counterfeit comprises the following steps：

S1 the false proof data preserved in bar code 100, i.e. authentication information) are obtained by bar code input module 200, And it is sent to safety chip 500.

S2）Decoding unit 501 in safety chip 500 is decoded to authentication information, then, judges that the bar code is It is no effective.Whether the foundation of judgement is consistent with prior art, that is, judge whether to meet default coding rule, and used Cross, etc..

S3）If the result of determination in S2 steps is invalid, judge that recognized consumptive material to be invalid, does not then perform phase Answer function and terminate.

S4）If the result of determination in S2 steps is effective, recognized consumptive material is judged to be effective, the safety chip Useful signal is sent to performing module 300 by 500.

S5）In the case of consumptive material identification is effective, performing module 300 performs corresponding action acquisition and performs data, and will Perform data and send safety chip 500 to.

S6）After 502 pairs of execution data of core algorithm unit in safety chip 500 are handled, and send result to Output module 400.

S7）Output module 400 is exported the result that core algorithm unit 502 is handled, and is finally completed the core of equipment Function.What is stored in the core algorithm unit 502 can be the crucial processing routine required for core algorithm or functions of the equipments, The sequential or driver element of such as control, prevent that evading realization by simple substituted after being destroyed for safety chip breaks through The problem of.

Fig. 3 is that the utility model is used for the circuit theory diagrams of the false proof chip circuit of analytical instrument reagent.Peace wherein used The MAPBGA of model K21 144 of full chip, USB interface is used for connecting bar code scanner, and 12pin-HEADER joints are used to control The performing modules such as motor processed, valve, pump, MAX197 chips are used to gather measurement data, and Ain0-Ain7 is signal input channel, LCD Module interfaces are used to connect LCD display.Method for anti-counterfeit in the utility model is realized in the chip circuit.

The false proof chip circuit of equipment consumptive material described in the utility model, by the safety chip set in a device, is used Safety chip stores key and decoding program, and is provided with determining program, starts when judging to receive physics decryption acts Self-destruction program, safety chip is destroyed, so that adding key cracks difficulty.Meanwhile, equipment consumption described in the utility model The false proof chip circuit of material makes user can not get around peace by the way that device core algorithm is stored in into processing mode in safety chip Full chip perform function, so as to ensure that the real control function of safety chip.

It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted, And all these modifications and variations should all belong to the protection domain of the utility model appended claims.
