A Kind of Electronic Cipher Lock
Based on Digital Circuit
[Abstract] A kind of new-type safe and more reliable lock which is called the electron chipher lock has been drawn from the problem of" opening each other" of the mechanical lock .This paper has analysed its characteristics and market prospects, introduced two kinds of electron chipher lock .One kind is based on circuit,whose characteristics is that if the key order of electron chipher lock is pressed wrongly ,the circuit is locked as the state of shutting of.The other kind is based on 74LS112 JK trigger a double-digital logic circuits which has simplify order collection with their easy to learn and cheap price which makes the developer able to get the dominant high-tech content electronic product from price, performance to privacy with low cost, short period, high return.At last,this paper has gived the improvement of electron chipper lock.
[Key words] Rate of opening each other；electron cipher lock；Interference bond；sleepmode
