Abstract
The utility model discloses a device for preventing pirating by using a serial number chip, which comprises a processor, wherein the processor also comprises the serial number chip and is connected with a pin of the serial number chip. The serial number chip connected with the processor is arranged in the device, thereby facilitating directly using the chip to tell the true from products utilizing the chip provided with an exclusive serial number.
Description
Technical field
The utility model belongs to the computer hardware technology field, relates to a kind of anti-piracy device, relates in particular to a kind of with the anti-piracy device of sequence number chip.
Background technology
The sequence number chip uses same bus for different products is general, and such purpose is to make different places place chip and because main frame can be discerned, just can not produce and not obscure.General product encryption method is a mode of checking key, product self release.In a single day this method is grasped by the imitator, can copy counterfeit products easily, and therefore, the mode and the imperfection of key, product self release checked in above-mentioned employing.
The utility model content
Technical problem to be solved in the utility model is: a kind of effectively anti-piracy device of sequence number chip that utilizes is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of described device comprises a processor with the anti-piracy device of sequence number chip, and described device comprises a sequence number chip, and described processor is connected with a pin of sequence number chip.
As a kind of preferred version of the present utility model, described sequence number chip is the digital temperature sensor chip.Further, described digital temperature sensor chip is digital temperature sensor 18B20.
As a kind of preferred version of the present utility model, the 2nd pin of described digital temperature sensor 18B20 is connected with processor, described the 2nd pin connects a pull-up resistor, the 3rd pin of described digital temperature sensor 18B20 is connected with processor by this pull-up resistor, described the 3rd pin connects power supply, the 1st pin ground connection of described digital temperature sensor 18B20.
As a kind of preferred version of the present utility model, the resistance of described pull-up resistor is 3000-6000 ohm.Further, the resistance of described pull-up resistor is 4700 ohm.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1, the utility model has disclosed a kind of anti-piracy device of sequence number chip of using, and described device comprises a single-chip microcomputer and a sequence number chip, and described single-chip microcomputer comprises a processor, and described single-chip microcomputer is connected with a pin of sequence number chip.
In the present embodiment, described single-chip microcomputer is MSP430, and described digital temperature sensor chip is digital temperature sensor DS18B20.
As shown in Figure 1, the 2nd pin of digital temperature sensor DS18B20 is connected with single-chip microcomputer MSP430, described the 2nd pin connects a pull-up resistor, the 3rd pin of described digital temperature sensor DS18B20 is connected with single-chip microcomputer by this pull-up resistor, described the 3rd pin connects power supply, the 1st pin ground connection of described digital temperature sensor DS18B20.
In the present embodiment, the resistance of described pull-up resistor is 4700 ohm.Certainly, the resistance of described pull-up resistor can be the arbitrary value in 3000-6000 ohm.
Fig. 2 is the process flow diagram of single-chip microcomputer working procedure, at first be this digital temperature sensor of initialization DS18B20, read the sequence number in the DS18B20 then, comprise 64 unique long sequence numbers in each DS18B20, the value of this sequence number leaves among the ROM of chip internal (ROM (read-only memory)).Judging that sequence number whether in the single-chip microcomputer product library, can use the method for partly searching of tearing open.At first be in subordinate ordered array, from the centre sequence be divided into two parts at every turn,, just continue to look for, till finding in less half if the data of looking for are littler than intermediate data.When sequence number not by the checking of single-chip microcomputer, then product reports an error and stops down to move.If by checking, the single-chip microcomputer detected temperatures is transferred to single-chip microcomputer, system normally moves.
The utility model is by adding the sequence number chip be connected with processor in device, thereby has in the product of chip of unique sequence number in utilization, can directly utilize this chip to distinguish the true and false of product easily.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only.Any modification or partial replacement that does not break away from the utility model spirit and scope all should be encompassed in the middle of the claim scope of the present utility model.
