Description

Wireless electron reaction type random cipher lock based on ARM9

Technical field

This practicality newly relates to a kind of coded lock, in particular, designs a kind of electronic lock of reaction type random cipher of Tong Guo the radio communication based on the ARM9 microprocessor.

Background technology

Coded lock is the main flow that contemporary society is put into technology, popular various forms of coded lock on the market, mechanical code lock is arranged, finger-print puzzle lock, card-scanning type coded lock etc., these locksets all have characteristics separately, but be accompanied by the now development of society, the single mode of unblanking coded lock can not be satisfied with people fully to the requirement of coded lock, single password can not play the effect of enough insurances, when the user tells other people password temporarily, worry again the problem of the permanent leakage of password, when making the user not near coded lock, when other people need to use the article that locked by coded lock, the user such as can not bring key again fast at the problem of some row, so, existing coded lock can not use existing high-tech art fully as the measure of maintaining secrecy, and also can't solve password in case reveal the series of problems that occurs, and very large hidden danger is arranged for like this information such as user's money and individual privacy.There is technological deficiency in existing technology, becomes the problem that those skilled in the art are badly in need of solving.

The utility model content

The ground problems such as password leakage appear for solving the secrecy provision imperfections such as the mode of unblanking that nowadays coded lock is single and password leakage, invented the wireless electron reaction type random cipher lock based on ARM9, this coded lock has been done larger improvement on function and aspect the encryption technology, abandoned the mode of conventional cipher lock employing single password, use the wireless technology based on ARM9 instead, and take full advantage of nowadays high-end network transmission technology, form by GPRS or 3g network insertion, realize the at random change of password and realize synchronous mode with terminal, also by senior AES, password is carried out superencipher and deciphering, solved the stolen problem of encrypted message in transmission course, and integrated embedded OS, for the user provides good pattern manipulation interface.

The technical scheme that the present invention adopts in the technical solution problem

Technical elements

1. the technology of encrypting and decrypting aspect: be locked in two places based on the wireless electron reaction type random cipher of ARM9 and adopted encryption technology, the firstth, the encryption technology between true form and the correspondence code, second is to containing the encryption technology of encrypted message in by the remote de-locking process, to encrypting in several ways between true form and the correspondence code, the user can set up on their own, but the user must remember this cipher mode that oneself is set, in order to directly calculate correspondence code by true form at random, cipher mode can be that Fourier changes cipher mode, Y=Ax2+bX+c etc.;

Internet Transmission and with the technology of mobile terminal synchronization aspect: based on the wireless electron reaction type random cipher Lock Lee of ARM9 with existing internet advantage, can this principle of real-time transmission data by gprs or 3g network, can realize the synchronous of information data with remote terminal, like this, can be by the method input correspondence code of remote de-locking, correspondence code is sent to this above coded lock from long-range terminal, realize authorization unlocking;

3. based on the technology of ARM9 microprocessor intelligence watch-dog aspect

The ARM9 microprocessor is most popular so far processor, adopt 5 level production lines, the pipeline design that increases has improved clock frequency and parallel processing capability, disposal ability to information data is also stronger, also increased simultaneously the better support to 3G network, so select the ARM9 microprocessor as core, by the fast processing of ARM9 microprocessor to the enciphered message of complexity, also can reach better the encrypting and decrypting effect, ARM9 microprocessor intelligence watch-dog just is responsible for monitor portion, as the mid portion of user and electronic lock, as long as the user wants to unblank, by inputting corresponding information, this intelligent monitor is determined the correctness of input message, if correct, unblank or information to the electromechanical lock transmission, if input message is not inconsistent, then do not send corresponding information, electromechanical lock still is in the lock state;

4. the technology of embedded OS aspect

Wireless electron reaction type random cipher lock based on ARM9 adopts embedded OS, and this embedded system is based on the ARM9 microprocessor, and the optimal design of doing for this coded lock specially, makes operation interface directly corresponding with the function of coded lock;

5. electromechanical lock

What the major part of locking based on the wireless electron reaction type random cipher of ARM9 adopted is common electromechanical lock, can realize unblanking and release by high-low level or the specific signal of input signal, like this, just with based on ARM9 microprocessor intelligence monitoring system be connected, electromechanical lock only is responsible for receiving unblanking or locking signal, is responsible for sending based on ARM9 microprocessor intelligence monitoring system and unblanks or locking signal.

For realizing the purpose of above technical scheme, content of the present utility model is:
