Description

Exceeding-normal coding high safety coded lock

A kind of exceeding-normal coding high safety coded lock belongs to the lock technology field, is mainly used on the burglary insurance facilities such as all exigent bank vault of degree of safety and confidentiality, safety cabinet, safe deposit box safe care registry, document databse, automobile, motorcycle, security door.

In prior art, coded lock miscellaneous is a lot, as mechanical, electronics, magnetic control or the like, but their coded system all is represent the conventional coding of the decimal system of one digit number with a numeral or letter, expressed information content very little, runin decoding easily, security is poor, as three-figure coded lock, at most only need runin 1000 times, No. 10000 locks of runin that only need of four figures can be opened.

The purpose of this utility model be to provide a kind of not only can be decimally but also other system exceeding-normal coding methods establishment passwords such as the available duodecimal notation, structure is unlike existing electronic password lock complexity, but its information content increases a lot, three-figurely increase by 1,000,000 times as metric, four figures increase several hundred million times, promptly Suo degree of safety and confidentiality can improve 1,000,000 to several hundred million times, may not decode with the runin method, be convenient to produce in enormous quantities and reduce cost, do not have double sign, of many uses, can remotely-controlled exceeding-normal coding high safety coded lock.

According to the basic principle and the implementation method of exceeding-normal coding, promptly as metricly can press on the lower keyboard several in 0～9 10 numeric keys simultaneously and represent one, be several digit codes with regard to simultaneously by several times, as

Three digit codes, press for the first time 1 and 4 two key simultaneously, for the second time press 6 simultaneously, 7,8 three keys, press 5 simultaneously more for the third time, 6,8,9 four keys, whenever by sending out a pulse behind the one digit number again, write down the number of at every turn pressing by trigger and can form one group of exceeding-normal coding, design the supporting with it electronic circuit that can realize this coding in view of the above, circuit is pressed right unconventional password electric motor starting by micro machine that is contained on the mechanical lock of relay control thus again, use one group of key again, dead bolt withdrawal coded lock promptly is opened, and key is extracted in the motor stall, dead bolt stretches out, and lock is locking once more.Thereby realization purpose of design.

Of the present utility modelly be characterised in that described exceeding-normal coding high safety coded lock, by the discrete separately keyboard [1] that is contained in usefulness lock device external surface, be contained in the mechanical lock [3] on the lock device wall and be contained in and constitute with controlling organization (micro computer) three major parts of locking the device inner surface, its distinguishing characteristics is: its above-mentioned keyboard [1] is for which is provided with power switch key # as shown in Figure 1, pulse generation key * and the button keyboard that is suitable for the decimal system number ten key of exceeding-normal coding, its above-mentioned mechanical lock [3] is by dead bolt [4], need simultaneously the supporting with it key [23] of usefulness (to draw in the structural representation when unblanking, only in wiring diagram, occur, and note is made K2) and the micro machine [2] that is fitted together with lock and the travel switch [21] that is contained in the lock (also draw in the structural representation, in wiring diagram, be labeled as K1 and K3) form, its above-mentioned controlling organization is then by according to eliminating waveform dither circuit [18], cryptochannel [19] and code signal amplification and motor start-up circuit [20] are installed in the hex inverter integrated package [5] on two wiring boards [7], two inputs four and door integrated package [6], two and the door integrated package [8] of four-input terminal, winding displacement [9], three inputs three and door integrated package [10], trigger integrated package [11], ternary R～S latched flip flop integrated package [12], resistance [13], electric capacity [14], triode [15], diode [16], controllable silicon [17] and relay [22] constitute, and are connected with inner wire by above-mentioned winding displacement [9] respectively between the micro machine [2] of above-mentioned keyboard [1] and mechanical lock [3] and the controlling organization.

The numerical key that is suitable for exceeding-normal coding that above-mentioned keyboard [1] which is provided with can be by pairing numeral of any system in other systems such as octal system, the duodecimal notation and hexadecimal and/or the strong replacement of letter.

Above-mentioned elimination waveform dither circuit [18] by above-mentioned ternary R～S latched flip flop [12] and be connected on its R and the resistance [13] of S end in R2, R1 forms, above-mentioned cryptochannel [19] is by above-mentioned hex inverter integrated package [5] two inputs four and door integrated package [6], two and the door integrated package [8] of four-input terminal, three inputs three and door integrated package [10], trigger integrated package [11] with respectively with resistance [13] that the Q4 end of the R of each trigger end and last trigger is connected in R3～4 and electric capacity [14] form, above-mentioned code signal amplification and motor start-up circuit [20] are by above-mentioned triode [15], diode [16], controllable silicon [17], R5～6 in the resistance [13], travel switch [21] (being K1 and K3) in the lock, relay [22] and micro machine [2] are formed, its preceding termination dc source VDD of above-mentioned circuit [18], and the pulse generation key * in the keyboard [1], the CP of each trigger end in its rear end connection circuit [19], its front end of circuit [19] is by above-mentioned hex inverter integrated package [5], two and the door integrated package [8] of four-input terminal, in two inputs four and the door integrated package [6] one with door and three inputs three and door integrated package [10] in one connect above-mentioned keyboard [1] with the four password Y1～Y4 and a winding displacement [9] of composition, its rear end is by R4 and triode [15] in electric capacity [14] connection circuit [20] and diode [16] in the resistance [13], diode [16] above-mentioned in the circuit [20] meets dc source VID, and relay [22] and microelectrode [2] respectively have a termination AC power.

The utility model has the advantages that: structure is unlike prior art like product complexity, but the information encoded amount increases a lot, and as decimal system routine: unconventional double figures is 10 * 10: $(C_{10}^1+C_{10}^2+C_{10}^3+C_{10}^4+C_{10}^5+C_{10}^6+$ $C_{10}^7+C_{10}^8+C_{10}^8+{C^{10}}_{10}{)}^2$ Promptly 100: 1023 ²=100: 1046529, three figure places are 100 * 10: 1023 ³=1000: 1070599167, four figures then is 1000 * 10: 1023 ⁴=10000: 10952229 * 10 ¹²And be that the multiple of the many more increases of figure place is many more, as with the duodecimal notation or hexadecimal, the multiple that increases is just more, therefore this coded lock is as getting four figures, then can not have the double sign sign indicating number in trillion sign indicating numbers, more difficult method with runin is decoded, and its security performance can't be compared with the existing like product of safe coefficient thus; Because information content is especially big, then is more convenient for producing in enormous quantities, thereby reduces cost.This lock can be used for the highly confidential and safe place of all needs in addition, arrives national treasury greatly, security door, and safety cabinet, strongbox, it is little that purposes is very extensive to the suitcase etc. of travelling, but also far distance controlled and the use of cooperation acousto-optic anti-theft alarm signal.
