In order further to improve the present invention, the present invention also makes full use of the effect of above-mentioned bell button, and its input end as the singly-bound password, the user just can make this device withdraw from the state of alert as long as push bell button by the preset password mode.Like this, the user damages, loses at telepilot etc. under the situation, can withdraw a garrison with this method, for the higher user of rule of life, by this method, even can carry telepilot.The ultimate principle of this button cipher code method is to have enrolled the button password program in the single-chip microcomputer, this program allows user to compile into one less than 16 password, as old-fashioned telegram emission key, the user is as long as press password, just can withdraw a garrison, for the guest, he is common bell button, and owner knows that but it has purposes in addition.If the thief wants that mala fide by repeatedly trying by coming decryption, this device also can be reported to the police.The detailed principle of singly-bound password, secrecy provision and programming method are as follows:

Detect with the input signal of single-chip microcomputer,, determine the numeral of input according to the time and the button different arrangements of trip time of pressing button in the input signal to button.During input digit, the user presses the certain speed pressing button, connect by under several, for example: connect by 5 times, representative is pressed into one-bit digital " 5 ", have a rest (time of this " a little while " will obviously be longer than with " connecting by under several " inner interval time in the one-bit digital), again by several (for example companies) down by 6 times, then import another one numeral " 6 " again, so press down, then available buttons input set of number, meanwhile, single-chip microcomputer carries out record timely to button information, and these information are analyzed, and just can determine one group of input digit " 56-----".

This device replaces " keyboard " with a button, and structure is simple especially, except this warning device uses, also can be installed in the place of bad installation common keyboard such as motorcycle handle; In addition, button profiles commonly used such as button in this device and common door bell button, car horn button are as broad as long, even available these buttons come dual-purpose, therefore, needs hide keyboard with the situation of maintaining secrecy under, use this device, be difficult for being found, destroyed; In addition, this device is because simple in structure, and failure rate is lower, and reliability is higher.

Is Fig. 5 a scm software theory diagram in this method, k among the figure? the expression single-chip microcomputer detects " button is arranged ".

SET represents the setting of the relevant constant of software, imports the number of times of error code etc. as initial number, initial figure place and permission;

T detects the time of pushing the ammonium button, calls compressing time in the following text, and for the button of normally opened contact, this is for connecting the circuit time.

T0 is detected relieving button time (the release button time).

T1 generally can be taken as about 10 milliseconds for allowing minimum compressing time.

T2 exceeds this time explanation user and does not understand input method or misoperation for allowing the longest compressing time, and general desirable T2 is 1-2 second.

T3 is for allowing the minimum button time of decontroling, and the too little relieving button time may be that the button shake causes that do not consider, general desirable T3 is about 10 milliseconds.

When T4 is a certain item sign indicating number of continuously input, allow the maximum quiescent interval (in the position intermittently) between adjacent secondary pressing button, the quiescent interval is judged to input next bit numeral when surpassing T4 (general about 1 second).

T5 is for allowing the quiescent interval of the maximum between position and the position, and it is too of a specified duration promptly to decontrol button above T5, means and does not understand operation (error), has perhaps imported to finish, and stops pressing button; The desirable 2-3 of T5 is about second; Greater than T4 a period of time, it is exactly above said " a little while " time less than T5.

Di is the size of button inputted i bit digital; Mi is the size that has the i bit digital of original code in the single-chip microcomputer (being stored in the password as the standard of comparison of input digit in the single-chip microcomputer in advance), and di=Mi illustrates that input i bit digital is correct.

Bi represents the figure place of input digit, Bm represents the original code figure place, bi=Bm represents that the figure place of input digit is enough, figure place is enough when importing, and the bits per inch word all equates, illustrate with button inputted set of number to be consistent expression button input digit correct (deciphering success) with the password of former setting.

Owner at one's side the time, several may the observed and memory for the stranger by sign indicating number, in order not allow stranger's memory cipher, prevents to reveal password, must take measures to upset stranger's memory during software design, has taked two kinds of measures among the present invention as stranger (onlooker):

(1) time-delay of certain hour is arranged after the deciphering success, if during this period, single-chip microcomputer detects pressing button (invalid button) in addition, and time-delay will continue so, after the deciphering success just, allow the unlimited invalid code of input.Begin part from t=0 among Fig. 5 to ok, the principle of having represented invalid key, wherein, t=0 represents to calculate above-mentioned delay time since 0, T0 represents to allow delay time under the unmanned pressing button situation, OK represents the relevant operation after the deciphering success, as withdraws from the state of alert or output signal is opened door lock etc. to start electromagnet.

(2) prevent to reveal the password purpose for same, also in order to prevent that the careless misoperation of owner from causing trouble, the software design of this device becomes to allow several times input password mistake, when the stranger is on the scene, owner can be deliberately one group of bad password of input earlier.The lower right corner is its software principle figure in this block scheme, and ni represents the factual error number of times among the figure; N represents to allow the number of times of input error; If actual input error number of times does not surpass the number of times that allows input error, then can re-enter, allow number of times then report to the police (WAR) if surpass.

In single-chip microcomputer, except compiling the listed software of Fig. 1, also should compile into password (above-mentioned original code) in advance, the software design of single-chip microcomputer should guarantee that the figure place of original code and numeral allow the user to select and compile voluntarily and revise.Significant datas such as original code and permission input error code number of times preferably are stored in the nonvolatile memory, also store with serial input nonvolatile memory 93C46 among the embodiment.

Far away from main frame when the button location, perhaps new house is decorated good inconvenience when line is installed, and can consider to utilize aforementioned bell button to launch the button password.
