The feature of the technical program is as follows：
Firstth, which has excellent protection as follows with using feature：
1) image input unit is constituted by the paintbrush for inlaying neodymium iron boron ball with the Hall array for adopting, defeated with " password "Enter mode and key materials exclusiveness physically.
2) lattice point of array quickly drawn on drawing board by paintbrush, and the track image for not producing paintbrush shows, improves figureThe disguise of shape input so that person agaainst the law is difficult to spy on.
3) as graphics track contains repeatability, unlike numerical ciphers are unique determinations and can not change, as long as thusFigure input ensures that intercepting the position of graphics track and track order meets " password ", and scheme can be opened with changeable graphics trackLock, with extremely strong strong fraudulence.
4) only identification intercepts the tablet pattern track of part for scheme unblock, is the innovative design that figure " password " is arranged, poleThe earth simplifies the memory difficulty to complicated figure.
Secondth, according to the " password for arranging：35207 ", and by " password " to tablet pattern and the agreement of intercepting figure, intelligenceLock system is only processed to the figure for intercepting and is recognized.If tablet pattern, intercepting figure and figure lattice point quantity meet " closeCode：35207 " agreement, the i.e. input of identification figure are correct, and then control to unlock.The execution implementation process of scheme is as follows：
1) main points of unblock figure input
1. " lighting drawing board " key is pressed, is pointed out：" can be with tablet pattern password " shows that intelligent lock system has been enter into reception figureThe state of shape input.At this point it is possible to passing through paintbrush drew Hall lattice point input unblock figure.Meanwhile, it is input into expiration timer TsrStart timing, a figure input restriction time is 20S.
2. need to only notice " password：35207 " description requirement, drew last three lattice points for intercepting successively：H3, H5, H2,And paintbrush drew lattice point quantity must not be less than 7 points outside, paintbrush can draw the Hall lattice point that you think that picture is crossed on drawing board.
2) process of unblock figure input
①Px.i=1？Identification microprocessor Px.iWhether mouth has signal input.If Px.i=1, show that paintbrush is drawn on drawing boardCross certain lattice point.Paintbrush every drew a Hall lattice point when, in microprocessor Px.iMouth will produce a signal input.
2. the precedence (or precedence of input signal generation) of lattice point is crossed in order to know picture, K is setjsOrder countDevice, executes Kjs=Kjs+ 1, accumulated counts were carried out when often drawing a lattice point.Meanwhile, execute DPx.i=Kjs, would indicate that successivelyThe count value of order is sent and deposits the sequence register DP being correspondingly arranged with Hall lattice pointx.iIn.
③Px.i=0 >=5S or Px.i=1 >=5S？Identification paintbrush leaves lattice point (Px.i=0) or Px.i=1 stagnates on lattice pointTime whether reach 5S.If Px.i=0 >=5S or Px.i=1 >=5S, then judge this figure end of input.
3) points of figure input are checked
1. figure end of input, first has to whether effectively check figure input points.Meet unblock figure input" password：35207 " point requirement, figure input is effectively.
②DPx.i≠ 0, Kds=Kds+ 1, check sequence register DP corresponding with Hall lattice point one by onex.iIn numerical value.AllIt is DPx.i≠ 0, then it represents that when figure is input into, the lattice point drawn by paintbrush.Dot counters execute Kds=Kds+ 1, thus, statistics is originallyAmount to the lattice point number that picture is crossed when secondary figure is input into.
③Kds≥7？When identification figure is input into, paintbrush drew whether the points of lattice point meet the requirements.Kds>=7, judge thisFigure input is effectively.
4) it is identified to intercepting figure
Figure input is intercepted.Identification：Intercept position of the figure in tablet pattern track, intercept figure lattice pointWhether ordering meets " password：35207 " description is input into by figure.
1. A=Dp1.3, B=Dp1.5, C=Dp1.2, intelligent lock system according to unblock figure " password " (35270) defeated to figureThe description for entering, automatically by corresponding for H3, H5, H2 lattice point sequence register DPx.iIn numerical value extract, and give successivelyA, B, C comparand register.
2. A ＞ Dpx.i＜ Dp1.5＜ Dp1.2？The order of H3 lattice points crossed by identification picture, if the secondary numerical sequence for drawing H3 lattice points is more thanThe secondary numerical sequence of other lattice points, is only smaller than the secondary numerical sequence of H5, H2 lattice point, then judge that H3 lattice points are the head for intercepting graphics trackPosition.
3. B ＞ Dpx.i＜ Dp1.2？The order of H5 lattice points crossed by identification picture, if the secondary numerical sequence for drawing H5 lattice points is more than other battle arraysThe secondary numerical sequence of point, is only smaller than the secondary numerical sequence of H2 lattice points, then judge that H5 lattice points are the secondary positions for intercepting graphics track.
4. C ＞ Dpx.i？The order of H2 lattice points crossed by identification picture, if the secondary numerical sequence for drawing H2 lattice points is secondary more than all lattice pointsNumerical sequence, then judge that H2 lattice points are the last positions for intercepting graphics track.
5. by unlocking figure input and the identification to unlocking figure input, track such as Fig. 4 of its figure input is accorded with completelyClose " password：35207 " description is input into by figure.Thus intelligent lock system display reminding：" the correct lock of input is opened ".
Process is realized from above-mentioned：If not attempt the requirement description that person of unlocking knows that " password " is input into figure, then" 352 " lattice point was drawn by paintbrush, was leaked through by paintbrush, not to mention was all placed on last three and was pointed with the finger or gesticulate, andAnd or by the picture of ordered arrangement.Therefore, method in scheme is succinct and safe.
5) restriction of figure input is processed
In order to improve unblock difficulty and the mental pressure of person agaainst the law, scheme has done some restrictions and place to unlocking figure inputReason is main as follows：
①Tsr≥20S？Recognize the cumulative time of this figure input, if reach the time limit.If the timer time limit does not arrive Tsr＜ 20S, then continue this figure input.If reaching time limit Tsr>=20S, then calculate this figure input error.
2. execute to error counter Kcw=Kcw+ 1, accumulated counts.Kcw=3？Errors number is identified, if Kcw＜ 3, intelligent lock system point out " input error is re-entered ".
If 3. Kcw=3, identification figure input error adds up to three times.For protecting the safety of householder's household, smart lockSystem closes figure input.Prompting：" three inputs of mistake are closed ".Event report is carried out to householder by GSM and is warnedAudible alarm.Close timer TgbStart timing.
④Tgb=30min？Identification closes whether timing reaches the time limit.If Tgb=30min, system voluntarily release input and closeClose.
⑤Tgb＜ 30min, " deblocking input " key are pressed, and input deblocking password correctly, then input is closed and released.
Beyond figure input is unlocked, lattice point in paintbrush contact array, then lattice point sort by number, can as 1,2 ... 9 numeral keys use.
Disclosed above is only the preferred embodiment of the present invention, but the present invention is not limited to this, any this areaWhat technical staff can think does not have a creative change, and some improvement that is made without departing from the principles of the present invention andRetouching, should all be within the scope of the present invention.
