Description

A kind of without key cipher door lock method

Technical field

The present invention relates to a kind of electronic cipher lockset, particularly a kind of without key cipher door lock method.

Background technology

Electronic password lock is used on door lock, lock or Safe lock as one safety, easily lockset in a large number, the same with existing lockset, electronic cipher lockset also needs key (except finger-print puzzle lock), electronic password lock adopts IC-card or radio-frequency card or Digiplex, it is good that radio-frequency card has safety, do not need the advantage of power supply, but electronic cipher lockset wants interval to power up provide power supply to radio-frequency card in time and read its encrypted message.

But be no matter that IC-card or radio-frequency card or Digiplex are once lose or forget to take with oneself, to open electronic cipher lockset, general mechanical lock can also look for people's idea of specialty to open lockset, but IC-card or radio-frequency card or Digiplex do not say general professional person, and expert also can not open lockset at short notice.

Finger-print puzzle lock then so not many troubles in this, refer to want your fingerprint stored in coded lock, in the process after, as long as gently press with finger, coded lock is then opened at the sound.Then, the price of finger-print puzzle lock is very high, is several times of general electronic cipher lockset.Secondly, to clean when your finger opens the door, earth or not dry quiet pollutant can not be had to exist.Otherwise want many stored in several finger print.

Summary of the invention

The object of the invention be to provide a kind of price low, easy to use without key cipher door lock method.

The present invention seeks to realize like this, a kind of without key cipher door lock method, it comprises lock body, lock body executing agency and controlling organization, lock body, lock body executing agency and controlling organization are arranged on latch position, it is characterized in that: have vibrating sensor at door body internal fixtion, controlling organization is by detecting vibration wave interval and the number of times of vibrating sensor induction, when the vibration wave interval produced by tap-tap is identical with the password formed by vibration wave interval and number of times that number of times and controlling organization store, controlling organization controls lock body executing agency and opens door lock, when the password bad of tap-tap input, controlling organization does not drive executing agency to open door lock.

The described vibration wave interval that produced by tap-tap and number of times are that to strike once door be 1 password, and striking secondary door is 2 passwords, tiredly in proper order push away.When password is 253986, first strike secondary door, then strike five doors, strike three subsequently, nine, eight, Lu Cimen, be interposed between in identical scope between knocking at the door at every turn.

Described vibrating sensor is piezoelectric transducer or miaow head.

The described vibration wave interval that produced by tap-tap and number of times are that to strike once door be 1+1 password, and striking secondary door is 2+1 password, tiredly in proper order push away.

The vibration wave interval produced by tap-tap due to the present invention and number of times form the encrypted message being input to controlling organization, this information forms the signal of telecommunication by vibrating sensor, by amplification and shaping circuit process, or directly sampled by the A/D converter of single-chip microcomputer, again by single-chip microcomputer process, form safe and reliable Password Input signal, by the codon pair ratio stored with memory, upon a match, controlling organization controls lock body executing agency and opens door lock, when not mating, controlling organization does not drive executing agency to open door lock.As long as be that anyone in family knows that encrypted message all can open door lock easily like this.

Detailed description of the invention

As shown in Figure 1, a kind of without key cipher door lock method, install lock body 2 in the position of the lock of door body 1, lock body 2 internal fixtion has controlling organization 4, vibrating sensor 3 and battery 5.

As shown in Figure 2, controlling organization 4 comprises: amplify and shaping circuit 401, single-chip microcomputer 402, lock body executing agency 403, the vibration signal that amplification and shaping circuit 401 pairs of vibrating sensors 3 produce carries out amplification shaping, the signal amplifying shaping, to the input port of single-chip microcomputer 402, carries out identifying processing by single-chip microcomputer 402 pairs of vibration signals.

Fig. 3 is given by the vibration signal schematic diagram that vibrating sensor 3 detects, it is the vibration signal figure of an input 3, as seen from the figure, the time t1, t2, t3 have three vibration signals respectively, the time interval of t1 and t2 and the time interval of t2 and t3 are in regular hour thresholding.

Fig. 4 is that the signal after amplification and shaping circuit 401 process is the square-wave signal of rule, and this signal delivers to the I/O mouth of single-chip microcomputer 402, carries out time interval measurement by single-chip microcomputer 402 to Fig. 3 signal through the signal amplified and obtain after shaping circuit 401 process.

Fig. 5 is undertaken knocking the sequential chart inputting complete password by opposite house body 1,6 passwords that have input one group 247491 are knocked by opposite house body 1, the time interval inputted between 2 and input 4 is greater than the time interval of t1 and t2 or the time interval of t2 and t3 as can be seen from Figure 5, equally, the time interval between input 4 and input 7 is greater than the time interval of t1 and t2 or the time interval of t2 and t3, by that analogy.That is, after every password figure input, when input Next Password numeral, will there be the time interval much larger than each password figure at its interval.This also does the correct identification be conducive to an input password figure.

In the present invention, vibrating sensor adopts the piezoelectric film vibrating sensor that piezoelectric film is manufactured, or adopts miaow head.

To amplify and amplifying circuit in shaping circuit 401 adopts automatic gain amplifier, be conducive to can effectively identifying the vibration signal of the tap-tap generation of little strength or micro-strength.In order to prevent tap-tap input password time password stolen by others.

On the other hand, door there is flexible sound absorption material 6, flexible sound absorption material 6 is knocked at the door produce sound very little, identify to single-chip microcomputer 402 to the shaping circuit energy signal that accurately shaping goes out when the amplifying circuit in amplification and shaping circuit 401 is enough to amplify this signal, only in this way just can not affect the safety and reliability of coded lock.
