Embodiment
Now the utility model is described, but Fig. 1-4 a kind of structure and mutual relationship of rotating disc type cipher input of input character have been shown with an embodiment.But the utility model be input character rotating disc type cipher input (Fig. 1) it by the electronic recognition control device with and the password input mechanism formed of turning handle 1, rotating shaft 7, positioning disk 8, infrared-emitting diode and infrared receiving diode 6 form; Electronic recognition control device (Fig. 5) comprising: single-chip microcomputer, storer, control interface, LCDs and function button.The password input mechanism is made up of turning handle 1, positioning disk 8, infrared-emitting diode and infrared receiving diode 6; Turning handle 1 is installed on the casing 9, and can rotate, turning handle and positioning disk are fixed in the rotating shaft 7, and infrared-emitting diode and infrared receiving diode are in the both sides of positioning disk respectively, be fixed on the photoelectricity support 5 of shell 9, infrared receiving diode sends the positional information of accepting to single-chip microcomputer.Be carved with character on the circumference of turning handle equably, come input digit and character by rotating the turning handle position; Be carved with 0-9 numeral and 26 English alphabets on the turning handle in this example, positioning disk has the concentric circles of three regular circular holes that distributing, the circular hole on these concentric circless respectively with turning handle on digital and English alphabet is corresponding.
The course of work of electronic recognition control device is:
Cipher input is that core is carried out work with the single-chip microcomputer." control interface " wherein is responsible for the message exchange of single-chip microcomputer and external unit." storer " is non-volatile electric erasable chip, and its content can be read and write and wipe, and is used to preserve password." infrared electro receiving tube " sends the positional information of accepting to single-chip microcomputer, and single-chip microcomputer at first finds the benchmark position, and the reposition of Zhuan Donging is calculated by single-chip microcomputer subsequently.Press the button on " function button ", can finish the management work of deletion to password, increase and decrease, modification etc." liquid crystal display " then is used to show various system informations and password.When password and the storage of input secret consistent, single-chip microcomputer sends corresponding signal by " control interface ", notifies external unit.
Be the scheme of wherein a kind of " numeral+English alphabet " below:
Setting by function button can the password input pattern be set to any one in following three kinds of patterns:
1, rotating " pattern.Any direction rotates turning handle 1 (supposing that password is abc), and when the letter on the turning handle 1 " a " arrived alignment point 2, (opposite with primary direction) rotated turning handle in the other direction, imports first character; Be rotated further turning handle, when the letter on the turning handle " b " arrived alignment point, (opposite with secondary direction) rotated turning handle in the other direction again, imports second character; In like manner import last character " c ", (opposite with direction for the third time) rotates turning handle in the other direction.The method for unlocking of this pattern and common traditional rotating disk coded lock is similar.Missing in the process can not be reverse behind the position of this character, need forward next circle to and select required character again.
2, " affirmation " pattern.Rotate turning handle 1 (supposing that password is abc), when the letter on the turning handle 1 " a " arrives alignment point 2,, import first character by " input " key (Fig. 5); Be rotated further turning handle, when the letter on the turning handle 1 " b " arrives alignment point 2,, import second character by " input " key; In like manner import last character " c " again.In alignment procedures turning handle at any time any direction rotate, but miss backward rotation behind the position of character.
3, " no turning handle " pattern.By " ∧ " or " ∨ " (Fig. 2 " on ", the D score key) key (suppose that password is abc), liquid crystal display 3 can show " 0～9 " individual numeral and " a～z " individual letter successively.When letter " a " occurring on the liquid crystal display,, import first character by " input " key; Continue by " ∧ " or " ∨ " key, when letter " b " occurring on the liquid crystal display,, import second character by " input " key; In like manner import last character " c " again.Emergent input after this pattern makes things convenient for turning handle malfunctioning.
More than in three kinds of patterns, if imported wrong character, can press the zero clearing of " restarting " key at any time, re-enter password.
The password input mechanism course of work is: when turning handle 1 rotated, positioning disk 8 and then rotated.Photoelectricity support 5 is fixed on the shell and does not rotate with turning handle 1, and three groups of infrared emission, infrared receiving diode 6 are installed on the photoelectricity support 5, and they are in the both sides of positioning disk 8 respectively, and the dish 8 that is positioned blocks.Three circle circular holes are arranged on the positioning disk 8, and when the position of circular hole is in the middle of the infrared emission, receiving tube, infrared light will pass on the infrared receiving diode that positioning disk 8 shines opposite side, and this signal is high level signal " 1 ".When sheltering from power valve, the signal that the reception infrared receiving diode receives is low level signal " 0 ".
At three concentric circless of positioning disk (Fig. 4) position distribution circular hole clocklike.If binary code " 1 " expression of porose position, the position that covers represents that with binary code " 0 " inner ring is represented a high position, and low level is represented in the outer ring, and then (ten) position can be represented with " 101 " among Fig. 4; (11) position can be represented with " 011 "; (12) position can be represented with " 001 ".Unique exception be exactly benchmark position (nine) it be expressed as " 111 ", and be only one, with its starting point as positioning disk.Repeat on disk remaining three value " 101 ", " 011 " and " 001 ".Can represent the rotation direction (Fig. 4) of positioning disk with these three values, if variation is " 101 " → " 011 " → " 001 " in proper order, then positioning disk clockwise rotates (among Fig. 4 shown in 14); If variation is " 001 " → " 011 " → " 101 " in proper order, then positioning disk rotates counterclockwise (among Fig. 4 shown in 13).
Its condition of work is to know the benchmark bit position, knowing rotation direction, knows that reposition can clearly be determined under the situation of rotating step number.Similar with the principle of mechanical mouse, MouseAcross disk with holes excessively passes through photoelectric tube successively, confirms rotation direction, rotates step number, and only mechanical mouse does not have the benchmark position.In secret sign indicating number input process, at least to need three circles of idle running earlier to reset the same with the rotating disc type mechanical code lock, and this cipher input needs sky to turn around at least, so that electronic-controlled installation finds the benchmark position, turn to any position then, control device can calculate.
Advantage: only need three groups of infrared diodes just can realize the judgement of any a plurality of positions to pipe, otherwise 36 (10 numeral+26 letters) positions need six groups of infrared diodes to pipe, 100 positions need 7 groups of infrared diodes to pipe, and 300 positions need 9 groups of infrared diodes to pipe ....And adopt such scheme even 1,000,10,000, and just can realize managing with three groups of infrared diodes, only need to revise Control Software and get final product.Can save cost, reduced volume, enhancing adaptability.
