House dog task dispatching, and glittering LED lamp indicates that system mode is normal in timer, and in this design, timing uses
Timer 0 carries out timing.In initialization, microcontroller timer 0 is arranged to 10ms Interruptions, i.e. microcontroller is every
10ms enters an Interruption.When microcontroller enters Interruption every time, system is counted using a timer interruption to be become
Amount counts 10ms Interruptions, when the variable is added to 10 multiple, illustrates that the system passes by 100ms, will
100ms timing indexs set one.Similarly, be added to 50 multiple i.e. 500ms be timed to come, system flow chart is illustrated in fig. 5 shown below：
Design of Software Anti-interference：In order to which system can normally be run, the factor of external interference should be by the weight of height
Depending on so this graduation project is provided with the program of Software Anti-interference.
To prevent program to be absorbed in endless loop, system uses " house dog " this Software for Design.Many times, due to some
Inevitable disturbing factor, either interruption subroutine can be in card machine or the state when machine, whole system to system main program
It cannot be monitored as usual, life property safety can be jeopardized.Therefore, setting in the defence of this graduation project this respect
It sets." house dog " technology is exactly the Software for Design of this subsystem design, its working principle is that：After system electrification is run, " guard the gate
Dog " timer starts therewith, in normal system operation, " house dog " timer self-clocking, and under normal condition, timing
Device automatic clear " house dog " after the numerical value for reaching setting；If " house dog " is not cleared and causes to overflow in a period of time
If, illustrate that system is absorbed in abnormal operating state, at this moment system can automatically reset, to re-start work.House dog work
It is illustrated in fig. 6 shown below as flow chart.
The realization of cell phone application end software function is as follows：
1. Software Development Tools
Android Studio (ends PC Android application development software)
2. software function upgrades
2.1 share (electronics) key
1, user selects to ask for key to good friend.
2, using generating a pair of of public-key cryptographic keys at random according to RSA Algorithm, and key is hidden and is stored in internal system, it will be public
Key addition is asked for key text (or Quick Response Code) and is encrypted.Key text (or Quick Response Code) is asked for what user's return generated.
3, user shares link (or Quick Response Code) to good friend.
4, application (or opening application scanning Quick Response Code) is opened after good friend's replication link text.
5, the interior RSA public keys for including of key text (or Quick Response Code) are asked in analytic application and acquisition, according to good friend's selection point
Receipt text (or Quick Response Code) is generated after the key encryption enjoyed.
6, good friend returns to receipt text (or Quick Response Code) to user (side of asking for).
7, application (or opening application scanning Quick Response Code) is opened after user's replication link text.
8, the information in analytic application receipt text (or Quick Response Code) and the RSA key decrypted text by generating before,
Successful decryption by the key shared after user's confirmation operation then by being added database.
2.2 opening door lock

System.
The key restrictive condition is inquired when 2, using by enabling the key every time to determine whether to send door open command.
(usage time interval etc. is limited in use, user carries out the operations such as offline adjustment time in order to prevent, using strong
User processed must connect network to ensure that the time is correct when using the key containing time restriction)
This software uses three-tier architecture, and project is roughly divided into presentation layer, Business Logic and data access layer.
1, presentation layer (User Interface Layer)：User interface.User's operation is transferred to service logic
Layer simultaneously responds user's operation according to the data of user logic layer return.
2, Business Logic (Business Logic Layer)：Function realizes module.Pass through data access layer execution pair
The operational set of data reaches the realization of function.
3, data access layer (Data Access Layer)：Data operation modules.The data progress additions and deletions of storage are changed and are looked into
The simple module of operation.
Specifically interaction design such as Fig. 7 between Software Architecture Design and each layering：
1.RSA public key encryption algorithms
RSA public-key encryptosystems.So-called public-key encryptosystem is exactly to use different encryption key and solution
Key is a kind of " it is infeasible to go out decruption key computationally by known encryption key derivation " cipher system.Open
In secret key cipher system, encryption key (i.e. public-key cryptography) PK is public information, and decruption key (i.e. privacy key) SK is to need
It to be maintained secrecy.Encryption Algorithm E and decipherment algorithm D is also disclosed.Although decruption key SK is determined by public-key cryptography PK,
But SK cannot be calculated according to PK.
And the realization with algorithm is based on a foolproof number theory fact：It is very easy that two big prime number is multiplied, but
It is intended to carry out factorization to its product extremely difficult, therefore product can be disclosed as encryption key[2]。
The algorithm of RSA is related to three parameters, n, e1、e2。
Wherein, n is the product of prime number p, q two big, when binary representation of n occupied digit, be exactly so-called key
Length.
e1And e2It is a pair of relevant value, e1It can arbitrarily take, but require e1It is relatively prime with (p-1) * (q-1)；Reselection e2,
Seek (e2*e1) mod (p-1) * (q-1)=1.
(n,e1),(n,e2) it is exactly key pair.Wherein (n, e1) it is public key, (n, e2) it is private key.
The algorithm of RSA encryption and decryption is identical, if A is in plain text, B is ciphertext, then：
(in public encryption system, generally using public key encryption, private key decryption)
E1 and e2 may be used interchangeably, i.e.,：
2. Quick Response Code transmits information
Quick Response Code usually described in everybody is to refer to matrix two-dimensional barcode, is built upon computer image processing technology
With a kind of basic raw encoding mechanism such as assembly coding principle.Principle is black by white point mainly in the region of a rectangle
The permutation and combination of point transmits information, and on some position, white point (null point) represents binary " 0 ", stain represent two into
" 1 " of system.
Square on three angles of Quick Response Code is called the anchor point of this Quick Response Code, there is these three points, no matter Quick Response Code
From which direction discernment, information can be correctly identified.A plane just be can determine due to 3 points, so the 4th of Quick Response Code the
A angle then saves come to store more information.
Just it is called the positioning pattern of Quick Response Code in two right-angle sides of the triangle that three anchor points are constituted, it determines two dimension
The coordinate of module in code.Separator is then the stray line being centered around around anchor point, its effect is by anchor point and other letters
Breath separates.
For each Quick Response Code there are one version number, the information of this version number is then stored at Quick Response Code lower left corner anchor point
Top.And the encoding format information of Quick Response Code just is then stored at the periphery of three anchor points.
In other regions of Quick Response Code, storage is exactly data information and error correction code information, when scanning input Quick Response Code,
It cannot be guaranteed that scanning is all correct to all information, at this moment error correcting code just works.
In addition, when Quick Response Code is maliciously torn to pieces, the correction figure positioned at Quick Response Code center then ensure that not by
Still it can normally be read the part torn to pieces.
The basic structure of one ordinary QR code is as shown in Figure 8：
Test and analysis of experimental results are as follows：
1. hardware system：Under the system primary condition, electromagnetic lock is closed, and is swiped the card, is identified successfully using correct IC card,
Lock is opened, and after maintaining 5 seconds open states, electromagnetic lock is automatically closed, and is connected fingerprint module, is inputted correct fingerprint, lock is opened.
2. mobile phone end system is as shown in table 1-4：
Table 1 adds door latch device test case
2 unlocking test case of table
3 door lock of table asks for test case
Table 4 shares the use limitation test case of door lock
3. analysis of experimental results
Find that 90% or so can be reached with the effective unlocking times of fingerprint by swiping the card, and failure conditions are happened at company by test
(if continuously swiped the card, unlocked by fingerprint etc.) when continuous progress unlocking operation.It, can be by each operation lock in improvement later
It is fixed, come the conflict for avoiding continuous operation from bringing and unlocking failure conditions.
In the test of Bluetooth information transmission, bluetooth connection success rate is 95% or so, when connection carries out bluetooth unlocking for the first time,
Send unlocking instruction after, it may appear that lose instruction the case where, but it is in stable condition after, lose instruction the case where can disappear.Through dividing
It analyses, flow of entirely unlocking under bluetooth original state is not very stable, but concrete reason is also to be determined.
To sum up, which realizes the requirement of initial design substantially under current state, but in system stability also
It needs to continue to improve.
Mobile phone terminal APP is applied at many aspects or cannot be met expectation of the user in terms of " convenient, safety ", such as
Share the cumbersome of key step, the insecurity of key information storage, and can not achieve user information between multiple equipment
Transfer operation etc..
In view of these situations, the cloud server that can subsequently establish the application, sale sex is ensured to high in the clouds.It will
All key informations store beyond the clouds, to replace dangerous situation key information being stored on personal mobile phone.It simultaneously can be with
